Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1.

Fig. 1 is a configuration diagram showing an elevator according to embodiment 1 of the present invention. In the figure, a car 3 and a counterweight 4 are provided in a hoistway 1. The car 3 and the counterweight 4 are vertically movable bodies in the hoistway 1. A machine room 2 is provided in an upper portion of the hoistway 1.

A hoisting machine 6 and a deflector sheave 7 are provided in the machine room 2. The hoisting machine 6 is a driving device that generates a driving force for moving the car 3 and the counterweight 4 in the vertical direction. The hoisting machine 6 also has a drive sheave 5 that is rotated by the drive force of the hoisting machine 6. The deflector sheave 7 is disposed apart from the drive sheave 5.

A plurality of elevator ropes 8 are wound around the drive sheave 5 and the deflector sheave 7. Examples of the elevator rope 8 include a long article formed by twisting a plurality of fibers and a long article formed by impregnating a plurality of fibers with a resin. The cross-sectional shape of each elevator rope 8 is a flat shape. That is, each elevator rope 8 is a belt having a flat-shaped cross section. The car 3 and the counterweight 4 are suspended in the hoistway 1 by elevator ropes 8. The car 3 and the counterweight 4 move in the vertical direction in the hoistway 1 in accordance with the rotation of the drive sheave 5.

A 1 st end structure 9 as an elevator rope end structure is provided at the 1 st end of each elevator rope 8. A 2 nd terminal structure 20 as an elevator rope terminal structure is provided at the 2 nd end of each elevator rope 8. Each 1 st end structure 9 is connected to an upper portion of the car 3. Each 2 nd terminal structure 20 is connected to the upper part of the counterweight 4. Thus, in this example, the car 3 and counterweight 4 are moved in a ratio of 1: 1 hanging in a rope winding way. The structure of the 2 nd terminal structure body 20 is the same as that of the 1 st terminal structure body 9.

Fig. 2 is a perspective view showing the 1 st end structure 9 of fig. 1. Fig. 3 is a front view showing the 1 st end structure body 9 of fig. 2. Fig. 4 is a side view showing the 1 st end structure body 9 of fig. 2. Fig. 5 is a side view showing the inside of the 1 st terminal structure body 9 of fig. 4. Fig. 6 is a perspective view showing the inside of the 1 st terminal structural body 9 of fig. 2. Fig. 7 is a sectional view taken along line VII-VII of fig. 5. Fig. 8 is a sectional view taken along line VIII-VIII of fig. 5.

The 1 st end structure 9 has: an insert 15 that is in contact with the elevator rope 8; a plurality of screws 13 serving as pressing portions for holding the insertion body 15 to the elevator rope 8; and a housing 10 that houses the elevator rope 8 and the insert 15.

The housing 10 has: a pair of parallel plates 101 arranged in parallel with each other; and a 1 st receiving plate 102 and a 2 nd receiving plate 103 which are disposed between the pair of parallel plates 101 so as to face each other. The 1 st receiving plate 102 is fixed to each of the pair of parallel plates 101. Further, the 2 nd receiving plate 103 is also fixed to each of the pair of parallel plates 101. That is, the housing 10 is configured by combining a pair of parallel plates 101, a 1 st receiving plate 102, and a 2 nd receiving plate 103.

The housing 10 is provided with a through hole 104 surrounded by a pair of parallel plates 101, a 1 st receiving plate 102, and a 2 nd receiving plate 103. The through hole 104 penetrates the housing 10. Thus, the through hole 104 has a cord passage opening as the 1 st opening and an insertion body opening as the 2 nd opening. The rope passage opening of the through hole 104 is provided at the longitudinal front end of the housing 10. The insertion opening of the through hole 104 is provided at the middle portion in the longitudinal direction of the housing 10. The elevator rope 8 and the insertion body 15 are held in the through hole 104.

As shown in fig. 7 and 8, the inner surface of the through hole 104 has a 1 st receiving surface 102a formed by the 1 st receiving plate 102 and a 2 nd receiving surface 103a formed by the 2 nd receiving plate 103. The 1 st receiving surface 102a and the 2 nd receiving surface 103a face each other in the width direction of the through hole 104. The distance between the 1 st receiving surface 102a and the 2 nd receiving surface 103a is continuously reduced from the insertion body opening of the through hole 104 toward the rope passage opening of the through hole 104. In this example, the 1 st receiving surface 102a and the 2 nd receiving surface 103a are inclined with respect to the axis of the housing 10.

A plurality of elongated holes 105 are provided in each parallel plate 101. The plurality of elongated holes 105 are provided at positions arranged along the 1 st receiving plate 102 at intervals from each other and at positions arranged along the 2 nd receiving plate 103 at intervals from each other. The 1 st receiving plate 102 and the 2 nd receiving plate 103 are fixed to the parallel plates 101 by a plurality of fixing screws 106 inserted through the elongated holes 105. The positions of the 1 st receiving plate 102 and the 2 nd receiving plate 103 with respect to the pair of parallel plates 101 can be adjusted by adjusting the positions of the fixing screws 106 in the respective elongated holes 105.

Each parallel plate 101 is provided with a mounting hole 107. Each mounting hole 107 is located at the rear end portion in the longitudinal direction of the housing 10. The 1 st end structure 9 is connected to the car 3 by means of mounting members passing through the mounting holes 107 of the 1 st end structure 9. On the other hand, the 2 nd terminal structure 20 is connected to the counterweight 4 via mounting members passing through the respective mounting holes of the 2 nd terminal structure 20.

The elevator rope 8 passes through the rope passage opening of the through-hole 104 from the outside of the housing 10 to the inside of the through-hole 104. The elevator rope 8 is provided with a 1 st rope surface and a 2 nd rope surface along the width direction of the elevator rope 8. The 1 st rope face and the 2 nd rope face are opposed to each other in the thickness direction of the elevator rope 8. The elevator rope 8 is inserted into the through hole 104 in a state where the 1 st rope surface faces the 1 st receiving surface 102a and the 2 nd rope surface faces the 2 nd receiving surface 103 a. Thus, the 1 st receiving surface 102a and the 2 nd receiving surface 103a are positioned on both sides in the thickness direction of the elevator rope 8.

The insertion body 15 has the 1 st insertion part 11 and the 2 nd insertion part 12. The 1 st insertion member 11 is disposed between the elevator rope 8 and the 1 st receiving surface 102 a. The 2 nd insertion member 12 is disposed between the elevator rope 8 and the 2 nd receiving surface 103 a. The 1 st insertion member 11 and the 2 nd insertion member 12 sandwich the elevator rope 8 in the thickness direction of the elevator rope 8.

The 1 st insertion member 11 is disposed in a state in which the longitudinal direction of the 1 st insertion member 11 coincides with the longitudinal direction of the elevator rope 8 and the width direction of the 1 st insertion member 11 coincides with the width direction of the elevator rope 8. The thickness direction of the 1 st insertion member 11 coincides with the thickness direction of the elevator rope 8.

The 2 nd insertion member 12 is disposed in a state in which the longitudinal direction of the 2 nd insertion member 12 coincides with the longitudinal direction of the elevator rope 8 and the width direction of the 2 nd insertion member 12 coincides with the width direction of the elevator rope 8. The thickness direction of the 2 nd insertion member 12 coincides with the thickness direction of the elevator rope 8. In this example, the width-direction dimensions of the 1 st insertion member 11 and the 2 nd insertion member 12 are larger than the width-direction dimension of the elevator rope 8.

The 1 st insertion member 11 is provided with a 1 st rope side facing surface 111 and a 1 st housing side facing surface 112. The 1 st housing-side facing surface 112 faces the 1 st rope-side facing surface 111 in the thickness direction of the 1 st insertion member 11. The distance between the 1 st cable-side facing surface 111 and the 1 st housing-side facing surface 112 decreases continuously from the insertion opening of the through hole 104 toward the cable passage opening of the through hole 104. Thereby, the 1 st insertion member 11 is formed in a wedge shape.

A pair of 1 st step portions 113 are provided at both ends in the width direction of the 1 st insertion member 11 along the longitudinal direction of the elevator rope 8. The pair of 1 st step portions 113 are located on both sides in the width direction of the 1 st case-side facing surface 112. Each 1 st step 113 is a recess recessed from the 1 st housing side facing surface 112 side toward the 1 st rope side facing surface 111.

Further, in the 1 st insertion member 11, bottom surfaces of the pair of 1 st step portions 113 are provided as the 1 st pressing surfaces 114 along the longitudinal direction of the elevator rope 8. Thus, the 1 st pressing surface 114 is located closer to the 1 st rope side facing surface 111 than the 1 st casing side facing surface 112 is. Each 1 st pressing surface 114 is parallel to the 1 st rope side facing surface 111.

The 1 st rope side facing surface 111 is in contact with the 1 st rope surface of the elevator rope 8. The 1 st housing-side facing surface 112 is in contact with the 1 st receiving surface 102 a. The 1 st pressing surfaces 114 are spaced apart from the inner surface of the through hole 104. Thereby, a space is generated between each 1 st pressing surface 114 and the inner surface of the through hole 104.

As shown in fig. 7 and 8, the 2 nd inserting member 12 is provided with a 2 nd rope side facing surface 121 and a 2 nd housing side facing surface 122. The 2 nd housing side facing surface 122 faces the 2 nd rope side facing surface 121 in the thickness direction of the 2 nd insertion member 12. The distance between the 2 nd rope side facing surface 121 and the 2 nd housing side facing surface 122 continuously decreases from the insertion body opening of the through hole 104 toward the rope passage opening. Thereby, the 2 nd insertion member 12 is formed in a wedge shape.

A pair of 2 nd step portions 123 are provided along the longitudinal direction of the elevator rope 8 at both ends in the width direction of the 2 nd insertion member 12. The pair of 2 nd step parts 123 are located on both sides in the width direction of the 2 nd housing-side opposite surface 122. Each 2 nd step part 123 is a recess recessed from the 2 nd housing side facing surface 122 side toward the 2 nd rope side facing surface 121.

Further, in the 2 nd insertion member 12, bottom surfaces of the pair of 2 nd step portions 123 are provided as the 2 nd pressing surfaces 124 along the longitudinal direction of the elevator rope 8. Thus, the position of each 2 nd pressing surface 124 is closer to the 2 nd rope side facing surface 121 than the position of the 2 nd casing side facing surface 122. Each 2 nd pressing surface 124 is parallel to the 2 nd rope side facing surface 121.

The 2 nd rope side opposite surface 121 is in contact with the 2 nd rope surface of the elevator rope 8. The 2 nd housing-side opposed surface 122 is in contact with the 2 nd receiving surface 103 a. Each 2 nd pressing surface 124 is spaced apart from the inner surface of the through hole 104. Thereby, a space is generated between each 2 nd pressing surface 124 and the inner surface of the through hole 104.

The 1 st insertion member 11 is provided with a plurality of through holes extending from the 1 st pressing surfaces 114 to the 1 st rope side facing surface 111. The plurality of through holes are provided at intervals from each other in the longitudinal direction of the 1 st insertion part 11. The 2 nd insertion member 12 is provided with a plurality of screw holes extending from the 2 nd pressing surfaces 124 to the 2 nd rope side facing surface 121. The plurality of screw holes are provided at intervals from each other in the longitudinal direction of the 2 nd insert member 12.

Each screw 13 is provided on the insertion body 15. The screws 13 are attached to the screw holes of the 2 nd insertion member 12 in a state of being inserted through the through holes of the 1 st insertion member 11. The screws 13 are disposed at intervals in the longitudinal direction of the insertion body 15. The screws 13 are disposed within a set range in the longitudinal direction of the insertion body 15. In this example, the set range in which each screw 13 is disposed is a range from the longitudinal rear end of the insertion body 15 to a position closer to the longitudinal front end than the center position of the insertion body 15.

As shown in fig. 5, each screw 13 is disposed at a position deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Thereby, the screws 13 are disposed so as not to penetrate the elevator rope 8. Further, each screw 13 is screwed into a screw hole of the 2 nd insertion member 12. The screws 13 fasten the elevator rope 8 and the insertion body 15 in a state of being screwed into the screw holes of the 2 nd insertion member 12.

Each screw 13 presses the insertion body 15 against the elevator rope 8 by fastening the elevator rope 8 and the insertion body 15. Thereby, the screws 13 apply pressing force to the insertion body 15 at positions deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Further, each screw 13 applies a pressing force to the insertion body 15 in a direction in which the 1 st insertion member 11 and the 2 nd insertion member 12 approach each other. The elevator rope 8 is held between the 1 st insertion member 11 and the 2 nd insertion member 12 by a pressing force applied to the insertion body 15 by tightening the screws 13.

The head of each screw 13 is disposed in a space between the inner surface of the through hole 104 and the 1 st pressing surface 114. Further, by screwing the screws 13 into the screw holes of the 2 nd insertion member 12, the heads of the screws 13 apply a pressing force to the 1 st pressing surface 114 to press the insertion body 15 against the elevator rope 8.

Each screw 13 maintains the state in which the insertion body 15 is pressed against the elevator rope 8 by maintaining the state in which the elevator rope 8 and the insertion body 15 are fastened. Thereby, the insertion body 15 is integrated with the elevator rope 8. Therefore, the state in which the insertion body 15 is held by the elevator rope 8 is maintained regardless of whether the insertion body 15 is inserted into the through hole 104.

The elevator rope 8 and the insertion body 15 are held between the 1 st receiving surface 102a and the 2 nd receiving surface 103 a. In the insertion body 15, the 1 st insertion part 11 is not fixed to the 2 nd insertion part 12, and the 1 st insertion part 11 and the 2 nd insertion part 12 are allowed to move in a direction to approach each other. Therefore, as the elevator rope 8 is pulled and the insertion body 15 moves toward the rope passage opening of the through hole 104, the 1 st insertion member 11 and the 2 nd insertion member 12 move in directions approaching each other by the guidance of the 1 st receiving surface 102a and the 2 nd receiving surface 103 a. As a result, the magnitude of the pressing force with which the insertion body 15 is pressed against the elevator rope 8 increases as the elevator rope 8 is pulled and the insertion body 15 moves toward the rope passage opening of the through hole 104.

In the 1 st terminal structure 9 and the 2 nd terminal structure 20, the state in which the insertion body 15 is pressed against the elevator rope 8 having a flat cross section is maintained by the plurality of screws 13. Therefore, the state in which the insertion body 15 is held by the elevator rope 8 can be maintained regardless of the presence or absence of the casing 10.

For example, when the elevator rope 8 is handled during the installation work of the elevator, the tension of the elevator rope 8 may be lost when the car 3 receives an impact and the elevator rope 8 swings when the car 3 is stopped in an emergency. In this case, the insertion body 15 may be detached from the insertion body opening of the through hole 104. In the present embodiment, even when the insertion body 15 is detached from the casing 10, the state in which the insertion body 15 is held by the elevator rope 8 can be maintained, and therefore the insertion body 15 can be easily inserted into the through hole 104 of the casing 10. Therefore, the state in which the insertion body 15 is inserted into the through hole 104 of the housing 10 can be easily and reliably secured.

The insertion body 15 further includes: a 1 st insertion member 11 disposed between the elevator rope 8 and the 1 st receiving surface 102 a; and a 2 nd insertion member 12 disposed between the elevator rope 8 and the 2 nd receiving surface 103 a. Therefore, the elevator rope 8 can be gripped between the 1 st insertion member 11 and the 2 nd insertion member 12. This makes it possible to easily maintain the state in which the insertion body 15 is held by the elevator rope 8. Even if the insertion body 15 falls off from the casing 10, the elevator rope 8 can be made difficult to fall off from the insertion body 15.

In the 1 st insertion member 11, the distance between the 1 st housing-side facing surface 112 and the 1 st cable-side facing surface 111 decreases as the cable passage opening extends toward the through hole 104. Therefore, the 1 st insertion member 11 can be easily inserted into the through hole 104. Further, the contact area of the 1 st insertion member 11 with respect to the elevator rope 8 and the 1 st receiving surface 102a can be increased. This can more reliably maintain the state in which the elevator rope 8 and the insertion body 15 are held in the through hole 104.

In the 2 nd insertion member 12, the distance between the 2 nd housing-side facing surface 122 and the 2 nd rope-side facing surface 121 decreases with the rope passage opening toward the through hole 104. Therefore, the 2 nd insertion member 12 can be easily inserted into the through hole 104. Further, the contact area of the 2 nd insertion member 12 with respect to the elevator rope 8 and the 2 nd receiving surface 103a can be increased. This can more reliably maintain the state in which the elevator rope 8 and the insertion body 15 are held in the through hole 104.

Further, by forming the 1 st insertion member 11 and the 2 nd insertion member 12 in the respective wedge shapes, the 1 st insertion member 11 and the 2 nd insertion member 12 can be formed in the same shape. This makes it possible to make the shapes of the components common and reduce the number of types of components. Further, the position of the elevator rope 8 in the through-hole 104 can be made close to the axis of the through-hole 104. This can reduce the lateral deviation of the force applied to the housing 10 when the elevator rope 8 is pulled.

Further, each screw 13 applies a pressing force to the insertion body 15 in a direction in which the 1 st insertion member 11 and the 2 nd insertion member 12 approach each other. Therefore, the elevator rope 8 can be gripped between the 1 st insertion member 11 and the 2 nd insertion member 12. This makes it possible to easily maintain the state in which the insertion body 15 is held by the elevator rope 8.

The insertion body 15 is provided with a 1 st pressing surface 114 spaced apart from the inner surface of the through hole 104. Then, the head of each screw 13 applies a pressing force to the 1 st pressing surface 114 to press the insertion body 15 against the elevator rope 8. Therefore, the head of each screw 13 can be disposed in the space generated between the inner surface of the through-hole 104 and the 1 st pressing surface 114, and the collision of each screw 13 with the inner surface of the through-hole 104 can be avoided.

The 1 st pressing surface 114 is a bottom surface of the 1 st step 113 provided as a recess of the insertion body 15. Therefore, a space can be more reliably generated between the inner surface of the through-hole 104 and the 1 st pressing surface 114.

The 1 st step 113 is provided in the insertion body 15 along the longitudinal direction of the elevator rope 8. Therefore, the insertion body 15 can be pressed against the elevator rope 8 in the longitudinal direction of the elevator rope 8. This enables the insertion body 15 to be more reliably held by the elevator rope 8.

Further, each screw 13 applies a pressing force to the insertion body 15 at a position deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Therefore, the pressing force can be applied to the insertion body 15 without penetrating the screws 13 through the elevator rope 8. This eliminates the need to form a hole for the screw 13 to pass through in the elevator rope 8.

The width-directional dimension of the insertion body 15 is larger than the width-directional dimension of the elevator rope 8. Therefore, even when the position of the elevator rope 8 with respect to the insertion body 15 is shifted in the width direction of the elevator rope 8, the insertion body 15 can be more reliably pressed against the elevator rope 8.

Further, each screw 13 presses the insertion body 15 against the elevator rope 8 by fastening the elevator rope 8 and the insertion body 15. Therefore, the state in which the insertion body 15 is pressed against the elevator rope 8 can be maintained with a simple structure.

The housing 10 is formed by combining a pair of parallel plates 101, a 1 st receiving plate 102, and a 2 nd receiving plate 103 with a fixing screw 106. Therefore, the case 10 can be manufactured using a common plate member and a common screw. This eliminates the need for a casting operation or a welding operation in manufacturing the case 10, and allows the case 10 to be easily manufactured in a short time. In addition, the case 10 of a special specification can be easily manufactured without mass production.

Embodiment 2.

Fig. 9 is a perspective view showing the 1 st terminal structure 9 as an elevator rope terminal structure according to embodiment 2 of the present invention. Fig. 10 is a front view showing the 1 st terminal structural body 9 of fig. 9. Fig. 11 is a side view showing the 1 st end structure body 9 of fig. 10. Fig. 12 is a side view showing the inside of the 1 st terminal structural body 9 of fig. 11. Fig. 13 is a perspective view showing the inside of the 1 st terminal structural body 9 of fig. 9. Fig. 14 is a sectional view taken along the line XIV-XIV of fig. 12. Fig. 15 is a sectional view taken along the XV-XV line of fig. 12.

The housing 10 is a single component. That is, the pair of parallel plates 101, the 1 st receiving plate 102, and the 2 nd receiving plate 103 of the housing 10 are formed by integral molding so as not to be disassembled. In this example, the housing 10 is a cast molded component. The 1 st receiving plate 102 and the 2 nd receiving plate 103 are respectively provided at four corners of the housing 10 with respect to the boundary of each parallel plate 101. The housing 10 has curved portions R formed at four corners thereof.

The screws 13 as the pressing portions are disposed only within a set range in the longitudinal direction of the insertion body 15. The set range in which each screw 13 is disposed is a range closer to the rear end portion side in the longitudinal direction of the insertion body 15 than the center position in the longitudinal direction of the insertion body 15. That is, each screw 13 is disposed only in a range on the side away from the rope passage opening of the through hole 104 of the two ranges obtained by dividing the longitudinal range of the insertion body 15 into two halves. Therefore, the pressing force that presses the insertion body 15 against the elevator rope 8 is applied to the 1 st pressing surface 114 within a set range of the rope passage opening apart from the through hole 104. The structure of the 2 nd terminal structure body 20 as the elevator rope terminal structure body is the same as that of the 1 st terminal structure body 9. The other structure is the same as embodiment 1.

In the 1 st and 2 nd terminal structures 9 and 20, the housing 10 is a single member. Therefore, as compared with embodiment 1, the strength of the case 10 can be increased, and the weight and size of the case 10 can be reduced.

The set range in which each screw 13 is disposed is a range closer to the rear end portion side in the longitudinal direction of the insertion body 15 than the center position in the longitudinal direction of the insertion body 15. Therefore, a space for disposing the head of each screw 13 can be ensured more reliably. That is, the space between the 1 st pressing surface 114 and the 1 st receiving surface 102a and the space between the 2 nd pressing surface 124 and the 2 nd receiving surface 103a become larger as they are closer to the rear end portion in the longitudinal direction of the insertion body 15. Thus, by concentrating the position of each screw 13 on the rear end side in the longitudinal direction of the insertion body 15, the space in which the head of each screw 13 is disposed can be enlarged. Therefore, the head of each screw 13 can be more reliably prevented from colliding with the inner surface of the through hole 104. In this case, the nut may be eliminated by providing a through hole through which the screw 13 is inserted in one of the 1 st insert member 11 and the 2 nd insert member 12, and providing a screw hole to which the screw 13 is attached in the other of the 1 st insert member 11 and the 2 nd insert member 12.

The angle of the 1 st housing-side facing surface 112 with respect to the 1 st rope-side facing surface 111 is defined as the angle of the longitudinal end of the 1 st insertion member 11, and the angle of the 2 nd housing-side facing surface 122 with respect to the 2 nd rope-side facing surface 121 is defined as the angle of the longitudinal end of the 2 nd insertion member 12. In this case, by setting the setting range for disposing each screw 13 to the rear end side in the longitudinal direction of the insertion body 15, the angle of the front end in the longitudinal direction of each of the 1 st insertion member 11 and the 2 nd insertion member 12 can be reduced. This makes it possible to make the insertion body 15 enter between the 1 st receiving surface 102a and the 2 nd receiving surface 103a further toward the rope passage opening of the through hole 104, and makes it possible to make it difficult for the insertion body 15 to come off from the through hole 104.

Further, the distribution of the magnitude of the pressing force with which the insertion body 15 presses the elevator rope 8 can be made smaller from the longitudinal direction rear end portion of the insertion body 15 to the longitudinal direction front end portion. Thus, the concentration of force on the elevator rope 8 can be alleviated at the boundary between the portion of the elevator rope 8 to which the insertion body 15 is pressed and the portion of the elevator rope 8 that comes out of the insertion body 15. Therefore, the breakage of the elevator rope 8 at the longitudinal direction front end portion of the insertion body 15 can be suppressed.

That is, the position of the longitudinal direction distal end portion of the insertion body 15 is a boundary position between a portion of the elevator rope 8 gripped by the insertion body 15 and a portion of the elevator rope 8 not gripped by the insertion body 15. Therefore, the elevator rope 8 swings or the pulling angle of the elevator rope 8 changes, so that fatigue occurs in the position of the longitudinal end of the insertion body 15 of the elevator rope 8, and the elevator rope 8 may break. In the present embodiment, the distribution of the magnitude of the pressing force with which the insertion body 15 presses the elevator rope 8 is reduced toward the longitudinal direction distal end portion of the insertion body 15, so fatigue of the elevator rope 8 at the position of the longitudinal direction distal end portion of the insertion body 15 can be suppressed.

In embodiments 1 and 2, the screw 13 inserted through the through hole of the 1 st insertion member 11 is attached to the screw hole of the 2 nd insertion member 12. However, the 1 st insertion member 11 may be provided with a plurality of screw holes extending from the 1 st pressing surfaces 114 to the 1 st rope side facing surface 111, and the 2 nd insertion member 12 may be provided with a plurality of through holes extending from the 2 nd pressing surfaces 124 to the 2 nd rope side facing surface 121. In this case, each screw 13 is attached to the screw hole of the 1 st insertion member 11 in a state of passing through the through hole of the 2 nd insertion member 12. In this case, the head of each screw 13 is disposed in a space between the inner surface of the through hole 104 and the 2 nd pressing surface 124. By screwing the screws 13 into the screw holes of the 1 st insertion member 11, the head of each screw 13 applies a pressing force to the 2 nd pressing surface 124 to press the insertion body 15 against the elevator rope 8.

In embodiments 1 and 2, the bottom surface of the 1 st step 113 as the recess is the 1 st pressing surface 114. However, the 1 st insertion member 11 may not be provided with a recess. For example, a plane parallel to the 1 st rope side facing surface 111 may be formed as the 1 st pressing surface at the longitudinal direction rear end portion of the 1 st insertion member 11. In this case, the 1 st pressing surface is a plane continuous from the 1 st casing side facing surface 112. Even in this case, a space can be created between the 1 st pressing surface and the 1 st receiving surface 102a, and a pressing force for pressing the insertion body 15 against the elevator rope 8 can be applied to the 1 st pressing surface by the pressing portion.

In embodiments 1 and 2, the bottom surface of the 2 nd step 123 serving as the recess is the 2 nd pressing surface 124. However, the 1 st insertion member 11 may not be provided with a recess. For example, a plane parallel to the 2 nd rope side facing surface 121 may be formed as the 2 nd pressing surface at the longitudinal direction rear end portion of the 2 nd insertion member 12. In this case, the 2 nd pressing surface is a plane continuous from the 2 nd casing side facing surface 122. Even in this case, a space can be created between the 2 nd pressing surface and the 2 nd receiving surface 103a, and a pressing force for pressing the insertion body 15 against the elevator rope 8 can be applied to the 2 nd pressing surface by the pressing portion.

Fig. 19 is a side view showing the inside of the 1 st terminal structural body 9 of fig. 18. Fig. 20 is a perspective view showing the inside of the 1 st terminal structure body 9 of fig. 16. Fig. 21 is a sectional view taken along line XXI-XXI of fig. 19. Fig. 22 is a sectional view taken along line XXII-XXII of fig. 19.

The housing 10 is a single component. That is, the pair of parallel plates 101, the 1 st receiving plate 102, and the 2 nd receiving plate 103 of the housing 10 are formed by integral molding so as not to be disassembled. In this example, the housing 10 is a cast molded component.

The 1 st receiving surface 102a is inclined in a direction approaching the axis of the housing 10 as going from the insertion opening of the through hole 104 to the rope passage opening of the through hole 104. The 2 nd receiving surface 103a is arranged along the axis of the housing 10. Thus, the shape of the housing 10 becomes an asymmetric shape protruding to one side.

A plurality of counterbores 115 having a circular cross section are provided at both ends in the width direction of the 1 st insert member 11. The counterbores 115 are disposed at intervals in the longitudinal direction of the elevator rope 8. Each counter bore 115 is a recess recessed from the 1 st case side facing surface 112 side to the 1 st rope side facing surface 111. The depth direction of each counterbore 115 coincides with the thickness direction of the 1 st insert member 11.

Further, the 1 st insert member 11 is provided with a bottom surface of each counterbore 115 as a pressing surface 116. Thus, the position of each pressing surface 116 is closer to the 1 st rope side facing surface 111 than the position of the 1 st casing side facing surface 112. Each pressing surface 116 is parallel to the 1 st rope side facing surface 111. Each pressing surface 116 is spaced apart from the inner surface of the through-hole 104. This creates a space in the counterbore 115 between each pressing surface 116 and the inner surface of the through-hole 104.

The 2 nd case side opposite surface 122 is parallel to the 2 nd rope side opposite surface 121. Thereby, the 2 nd insertion member 12 is formed into a flat plate shape. In this example, the thickness of the 2 nd insertion member 12 is smaller than that of the 1 st insertion member 11 at any position in the longitudinal direction of the insertion body 15. The 2 nd rope side opposite surface 121 is in contact with the 2 nd rope surface of the elevator rope 8. The 2 nd housing-side opposed surface 122 is in contact with the 2 nd receiving surface 103 a. Thus, the elevator rope 8 inserted into the through hole 104 is disposed so as to be inclined with respect to the 1 st receiving surface 102a and parallel to the 2 nd receiving surface 103 a.

The 1 st insertion member 11 is provided with a plurality of through holes reaching the 1 st rope side facing surface 111 from the respective pressing surfaces 116. The inner diameter of each through-hole is smaller than the inner diameter of each counterbore 115. The 2 nd insertion member 12 is provided with a plurality of screw holes extending from the 2 nd rope side facing surface 121 to the 2 nd housing side facing surface 122.

Each screw 13 is attached to the screw hole of the 2 nd insertion member 12 in a state of being inserted through the through hole of the 1 st insertion member 11. The screws 13 are disposed at intervals in the longitudinal direction of the insertion body 15. The screws 13 are disposed within a set range in the longitudinal direction of the insertion body 15. In this example, the set range in which each screw 13 is disposed is a range from the longitudinal rear end of the insertion body 15 to a position closer to the longitudinal front end than the center position of the insertion body 15.

As shown in fig. 19, each screw 13 is disposed at a position deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Thereby, the screws 13 are disposed so as not to penetrate the elevator rope 8. Further, each screw 13 is screwed into a screw hole of the 2 nd insertion member 12. The screws 13 fasten the elevator rope 8 and the insertion body 15 in a state of being screwed into the screw holes of the 2 nd insertion member 12.

Each screw 13 presses the insertion body 15 against the elevator rope 8 by fastening the elevator rope 8 and the insertion body 15. Thereby, the screws 13 apply pressing force to the insertion body 15 at positions deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Further, each screw 13 applies a pressing force to the insertion body 15 in a direction in which the 1 st insertion member 11 and the 2 nd insertion member 12 approach each other. The elevator rope 8 is held between the 1 st insertion member 11 and the 2 nd insertion member 12 by a pressing force applied to the insertion body 15 by tightening the screws 13.

The head of each screw 13 is disposed in the space within counterbore 115. Further, by screwing the screws 13 into the screw holes of the 2 nd insertion member 12, the heads of the screws 13 apply pressing forces to the pressing surfaces 116 to press the insertion bodies 15 against the elevator rope 8. The other structure of the 1 st end structure body 9 is the same as that of the 1 st end structure body 9 in embodiment 1. Further, the structure of the 2 nd terminal structure body 20 as the elevator rope terminal structure body is the same as that of the 1 st terminal structure body 9. The other structure is the same as embodiment 1.

In the 1 st and 2 nd terminal structures 9 and 20, the 2 nd case side facing surface 122 is parallel to the 2 nd rope side facing surface 121. Therefore, the 2 nd insertion member 12 can be formed in a flat plate shape. This can reduce the dimension of the 2 nd insertion member 12 in the thickness direction, and can reduce the size of the housing 10. Further, the shape of the housing 10 can be formed to be asymmetrical. Therefore, by selecting a direction in which the housing 10 does not protrude and disposing the housing 10, it is possible to avoid the housing 10 from colliding with other devices.

Further, the bottom surface of the 1 st insert member 11 provided with the plurality of counter bores 115 serves as a pressing surface 116. Therefore, the space for securing the pressing surface 116 in the 1 st insert member 11 can be reduced. This can increase the area of the 1 st housing-side facing surface 112, and can make it difficult for the insertion body 15 to come off the through hole 104.

Further, a plurality of counterbores 115 are provided in the 1 st insert member 11. Therefore, the depth of the counterbore 115 can be deepened. That is, since the 1 st insertion member 11 has a wedge shape, the thickness of at least a part of the 1 st insertion member 11 is larger than the thickness of the 2 nd insertion member 12. Therefore, by providing the counterbore 115 in the portion of the 1 st insert member 11 having a large thickness, the depth of the counterbore 115 can be ensured. This enables the head of the screw 13 to be more reliably disposed in the space in the counterbore 115, and the head of the screw 13 to be more reliably prevented from colliding with the inner surface of the through-hole 104.

In addition, in the above example, a plurality of counterbores 115 are provided in the 1 st insert member 11. However, a plurality of counterbores 115 may be provided in the 2 nd insert member 12. In this case, a pressing surface 116 as a bottom surface of each counterbore 115 is provided on the 2 nd insert member 12. In this case, a plurality of through holes through which the screws 13 are inserted are provided in the 2 nd insertion member 12, and a plurality of screw holes to which the screws 13 are attached are provided in the 1 st insertion member 11. Even in this way, the insertion body 15 can be pressed against the elevator rope 8 by screwing the screw 13 inserted through the through hole of the 2 nd insertion member 12 into the screw hole of the 1 st insertion member 11.

Fig. 28 is a side view showing the inside of the 1 st terminal structural body 9 of fig. 27. Fig. 29 is a perspective view showing the inside of the 1 st terminal structural body 9 of fig. 23. Fig. 30 is a cross-sectional view taken along line XXX-XXX of fig. 28. Fig. 31 is a cross-sectional view taken along line XXXI-XXXI of fig. 28. Fig. 32 is a cross-sectional view taken along line XXXII-XXXII of fig. 26.

The width-directional dimension of the insertion body 15 is the same as the width-directional dimension of the elevator rope 8. As shown in fig. 32, both end surfaces in the width direction of each of the 1 st insertion member 11 and the 2 nd insertion member 12 are separated from the inner surface of the through hole 104. This generates a space between both end surfaces in the width direction of each of the 1 st insertion member 11 and the 2 nd insertion member 12 and the inner surface of the through hole 104.

A plurality of clips 130 as pressing portions are disposed in spaces generated between both end surfaces in the width direction of each of the 1 st insertion member 11 and the 2 nd insertion member 12 and the inner surface of the through hole 104. In this example, two clips 130 are disposed on both sides of the insertion body 15 in the width direction. Each clip 130 is provided on the insertion body 15.

Each clip 130 has a clip main body 131 fixed to the width-direction end face of the 1 st insertion member 11 and a fixing hook 132 fixed to the width-direction end face of the 2 nd insertion member 12.

The clamp body 131 has a movable hook capable of hooking the fixed hook 132 and an operating lever for moving the movable hook with respect to the 1 st insertion part 11. Each clip 130 is pulled close to a fixed hook 132 to which a movable hook is hooked by an operation of an operation lever through a clip main body 131, and presses the insertion body 15 against the elevator rope 8. Thereby, the clamping members 130 apply a pressing force to the insertion body 15 at positions deviated from the region of the elevator rope 8 when viewed in the thickness direction of the elevator rope 8. Further, each clip 130 applies a pressing force to the insertion body 15 in a direction in which the 1 st insertion member 11 and the 2 nd insertion member 12 approach each other. Therefore, the elevator rope 8 is held between the 1 st insertion member 11 and the 2 nd insertion member 12 by the pressing force of the respective clamps 130.

Each clip 130 maintains the state in which the insertion body 15 is pressed against the elevator rope 8 by maintaining the state in which the fixed hook 132 to which the movable hook is hooked is pulled close to the clip main body 131. Thereby, the state in which the insertion body 15 is held by the elevator rope 8 is maintained regardless of whether the insertion body 15 is inserted into the through hole 104. The other structure of the 1 st end structure body 9 is the same as that of the 1 st end structure body 9 in embodiment 3. Further, the structure of the 2 nd terminal structure body 20 as the elevator rope terminal structure body is the same as that of the 1 st terminal structure body 9. The other structure is the same as embodiment 1.

In the 1 st and 2 nd terminal structures 9 and 20, the plurality of clips 130 having the clip main bodies 131 and the fixing hooks 132 are used as pressing portions. Therefore, the operation of pressing the insertion body 15 against the elevator rope 8 can be easily performed only by pulling the fixing hook 132 close by the clip main body 131 hooking the fixing hook 132.

The setting range in which each clip 130 is disposed may be set to a position closer to the rear end portion side in the longitudinal direction of the insertion body 15 than the center position in the longitudinal direction of the insertion body 15. In this way, similarly to embodiment 2, breakage of the elevator rope 8 at the longitudinal direction distal end portion of the insertion body 15 can be suppressed. Further, a space in which each clip 130 is disposed can be more reliably secured.

In the above example, the width-directional dimension of the insertion body 15 is the same as the width-directional dimension of the elevator rope 8. However, the width-directional dimension of the insertion body 15 may be made larger than the width-directional dimension of the elevator rope 8. In this way, even when the position of the insertion body 15 is shifted in the width direction of the elevator rope 8, the insertion body 15 can be more reliably pressed against the elevator rope 8.

In the above example, the clip main body 131 is provided on the 1 st insertion member 11, and the fixing hook 132 is provided on the 2 nd insertion member 12. However, the fixing hook 132 may be provided on the 1 st insertion member 11 and the clamp body 131 may be provided on the 2 nd insertion member 12.

FIG. 43 is a cross-sectional view taken along line XXXIII-XXXIII in FIG. 39.

The insertion body 15 has a 1 st insertion part 11 and a pair of 2 nd insertion parts 12. The structure of the 1 st insertion member 11 is the same as that of embodiment 1.

The pair of 2 nd insertion members 12 are disposed between the elevator rope 8 and the 2 nd receiving surface 103a along the longitudinal direction of the elevator rope 8. Further, the pair of 2 nd insertion members 12 are disposed apart from each other in the width direction of the elevator rope 8. Thereby, one widthwise end portion of the elevator rope 8 is sandwiched between one widthwise end portion of the 1 st insertion member 11 and one 2 nd insertion member 12. The other end in the width direction of the elevator rope 8 is sandwiched between the other end in the width direction of the 1 st insertion member 11 and the other 2 nd insertion member 12.

As shown in fig. 43, each 2 nd insertion member 12 is provided with a 2 nd rope side facing surface 121 and a 2 nd housing side facing surface 122. The 2 nd housing side facing surface 122 faces the 2 nd rope side facing surface 121 in the thickness direction of the 2 nd insertion member 12. The 2 nd case side opposite surface 122 is parallel to the 2 nd rope side opposite surface 121. Thereby, the 2 nd insertion member 12 is formed into a flat plate shape.

Each 2 nd insertion member 12 is provided with a plurality of screw holes extending from the 2 nd rope side facing surface 121 to the 2 nd housing side facing surface 122. In each 2 nd insert member 12, a plurality of screw holes are provided at intervals from each other in the longitudinal direction of the 2 nd insert member 12.

The screws 13 as the pressing portions are attached to the screw holes of the 2 nd inserting members 12 in a state of being inserted through the through holes of the 1 st inserting member 11. As in embodiment 1, the screws 13 fasten the elevator rope 8 and the insertion body 15 while being screwed into the screw holes of the 2 nd insertion members 12. Both ends in the width direction of the elevator rope 8 are held between the 1 st insertion member 11 and the 2 nd insertion member 12 by pressing forces applied to the insertion body 15 by tightening the screws 13.

As shown in fig. 42 and 43, the 2 nd receiving surface 103a includes: a pair of insertion body contact surface portions 21 separated from each other in the width direction of the elevator rope 8; and a rope contact surface portion 22 located between the pair of insertion body contact surface portions 21. The rope contact surface portion 22 and the pair of insertion body contact surface portions 21 are formed along the longitudinal direction of the elevator rope 8. The rope contact surface portion 22 is formed at a position closer to the 1 st receiving surface 102a than the positions of the pair of insertion body contact surface portions 21.

The 2 nd rope side facing surface 121 of each 2 nd insertion member 12 contacts the 2 nd rope surface at both ends in the width direction of the elevator rope 8. The 2 nd housing-side facing surface 122 of each 2 nd insertion member 12 is in contact with the pair of insertion body contact surface portions 21 of the 2 nd receiving surface 103 a. The rope contact surface portion 22 of the 2 nd receiving surface 103a contacts the 2 nd rope surface of the widthwise intermediate portion of the elevator rope 8. Therefore, the rope contact surface portion 22 of the 2 nd rope side facing surface 121 and the 2 nd receiving surface 103a of each 2 nd insertion member 12 is in contact with the 2 nd rope surface of the elevator rope 8. The other structure of the 1 st end structure body 9 is the same as that of the 1 st end structure body 9 in embodiment 3. Further, the structure of the 2 nd terminal structure body 20 as the elevator rope terminal structure body is the same as that of the 1 st terminal structure body 9. The other structure is the same as embodiment 1.

In the 1 st terminal structural body 9 and the 2 nd terminal structural body 20, the rope contact surface portion 22 of the 2 nd receiving surface 103a is in contact with the elevator rope 8. Therefore, the elevator rope 8 and the insertion body 15 can be held in the through hole 104 not only by the frictional force between the casing 10 and each 2 nd insertion member 12 but also by the frictional force between the casing 10 and the elevator rope 8. Accordingly, the frictional force of the housing 10 against the elevator rope 8 and the 2 nd insertion member 12 made of different materials can be adjusted, and the frictional force necessary to hold the elevator rope 8 and the insertion body 15 in the through hole 104 can be easily adjusted.

In the above example, the pair of insert contact surface portions 21 of the 2 nd receiving surface 103a contact the 2 nd insert member 12. However, each 2 nd inserting member 12 may not be provided. In this case only the 1 st insert part 11 is fastened to the elevator rope 8 by a number of screws 13. In this case, the screws 13 are screwed into the screw holes of the 1 st insertion member 11 with both ends of the 1 st elevator rope 8 in the width direction being sandwiched between the heads of the screws 13 and the 1 st insertion member 11. Thereby, the 1 st insertion member 11 is pressed to the elevator rope 8. Even in this way, the insertion body 15 can be held by the elevator rope 8 regardless of the presence or absence of the housing 10, and the elevator rope 8 and the insertion body 15 can be held between the 1 st receiving surface 102a and the rope contact surface portion 22.

In the above example, a plurality of through holes through which the screws 13 are inserted are provided in the 1 st insertion member 11, and a plurality of screw holes to which the screws 13 are attached are provided in each of the 2 nd insertion members 12. However, a plurality of through holes through which the screws 13 are inserted may be provided in each of the 2 nd insertion members 12, and a plurality of screw holes to which the screws 13 are attached may be provided in the 1 st insertion member 11. Even in this way, the insertion body 15 can be pressed against the elevator rope 8 by screwing the screw 13 inserted through the through hole of the 2 nd insertion member 12 into the screw hole of the 1 st insertion member 11.

In embodiments 1 to 3 and 5, the pressing portion that presses the insertion body 15 against the elevator rope 8 is the screw 13. However, the pressing portion that presses the insertion body 15 against the elevator rope 8 may have a screw and a nut. In this case, the 1 st insertion member 11 and the 2 nd insertion member 12 are provided with a plurality of through holes, respectively. In this case, the nut of the pressing portion is attached to a screw of the pressing portion which sequentially passes through the through holes of the 1 st insertion member 11 and the 2 nd insertion member 12. The 1 st insertion member 11, the 2 nd insertion member 12, and the elevator rope 8 are fastened between the head of the screw and the nut by screwing the nut into the screw. The screws and nuts press the insertion body 15 against the elevator rope 8 by tightening the 1 st insertion member 11, the 2 nd insertion member 12, and the elevator rope 8. Even in this case, the state in which the insertion body 15 is pressed against the elevator rope 8 can be maintained with a simple structure.

When the pressing portion includes a screw and a nut, a spring washer as an elastic member may be interposed between at least one of the head of the screw and the insertion body 15 and between the nut and the insertion body 15. In this case, the screw and the nut for fastening the elevator rope 8 and the insertion body 15 can be made difficult to loosen. This can more reliably maintain the state in which the insertion body 15 is pressed against the elevator rope 8.

In embodiments 1 to 3 and 5, the head of each screw 13 is in contact with the insertion body 15. However, a spring washer as an elastic member may be interposed between the head of each screw 13 and the insertion body 15. In this way, the screws 13 that fasten the elevator rope 8 and the insertion body 15 can be made less likely to loosen. This can more reliably maintain the state in which the insertion body 15 is pressed against the elevator rope 8.

In embodiments 1 to 3 and 5, the screws 13 are disposed on the outer side in the width direction of the elevator rope 8. However, the screws 13 may also penetrate the elevator rope 8.

In embodiments 3 to 5, the 2 nd insertion member 12 has a flat plate shape. However, the 2 nd insertion member 12 may be formed in a wedge shape. That is, in the 2 nd insertion member 12, the distance between the 2 nd housing side facing surface 122 and the 2 nd rope side facing surface 121 may be continuously decreased as the rope passage opening toward the through hole 104.

In each of the above embodiments, the car 3 and the counterweight 4 are arranged in a ratio of 1: 1 hanging in a rope winding way. However, the elevator ropes 8 may be wound around a car suspension sheave provided in the car 3 and a counterweight suspension sheave provided in the counterweight 4, and the 1 st terminal structure body 9 and the 2 nd terminal structure body 20 may be mounted on the upper portion of the hoistway 1, respectively, so that the car 3 and the counterweight 4 are supported by a 2: 1 hanging in a rope winding way.

In each of the above embodiments, the 1 st terminal structure 9 and the 2 nd terminal structure 20 are applied to an elevator rope terminal structure of an elevator in which a machine room is installed in an upper part of a hoistway. However, the 1 st end structure 9 and the 2 nd end structure 20 may be applied to an elevator rope end structure of a machine-roomless elevator in which no machine room is installed.
