Technical Field

The invention relates to the technical field of elevators, in particular to a suspension rail type escalator.

Background

At present, with the accelerated arrival of population aging, the addition of elevators in old communities becomes a civil engineering which is advocated by the nation and has urgent needs of common people. At present, the old community is additionally provided with elevators mainly by the following three modes: firstly, the traditional vertical elevator; secondly, a straight rail type escalator is installed by depending on the surface of the stairs; and thirdly, the rotary type escalator is arranged at the handrail part of the stair. The three elevators can solve the problem of going upstairs and downstairs traveling of high-rise residents due to the fact that the existing old community has no elevator to a certain extent. But because of the inherent characteristics of the old cells, various contradictions and disadvantages exist in the process of installing the elevator in the old cells, the popularization difficulty is high, and the specific analysis is as follows:

firstly, the defects and contradiction points existing in old community reconstruction of the traditional vertical elevator are analyzed:

the elevator is characterized in that an elevator shaft is additionally arranged on the outer vertical surface of an old community, an original corridor ventilating window of the community is transformed into an entrance door opening of the elevator, and an elevator shaft is connected with the flat-layer stair surface of the old community by building a corridor. The elevator car vertically runs in the elevator shaft, and vertically lifts a user to a target floor to solve the problem of going upstairs and downstairs. The elevator consists of a traction system, a safety system, a counterweight balancing device, a control system, a car and the like, and the main principle of the elevator is that a traction motor pulls the car to vertically ascend or descend so as to achieve the purpose of conveying passengers to a specific floor. Because the elevator has the advantages of mature technology, safety, reliability, elegant appearance, large carrying capacity, high operating efficiency, simple and convenient operation and the like, the elevator becomes a main mode for additionally installing elevators in the current old communities. However, in the old cell reconstruction specific implementation process of the elevator, the following problems are found:

firstly, the engineering cost is high. Currently, the cost of installing a 6-deck car type vertical lift elevator is generally about 40 to 60 ten thousand, even if the government subsidies fifty percent in some regions, more than twenty thousand costs are shared by the owners, and the cost is still not small for each household. This limits to some extent the attractiveness of an old cell to install elevators.

Secondly, the construction period is long. After the owner reaches the installation agreement, the elevator constructor needs to survey the construction site and design and manufacture the construction drawing, and can really enter the construction stage after the construction drawing is finished. In the construction process, the elevator shaft is built in a mode of increasing progressively layer by layer, namely after the frame is built on the first floor, the frame on the second floor can be constructed, and multiple layers of frames cannot be constructed simultaneously, so that the operation efficiency is limited to a certain extent. Therefore, the current work period of installing the vertical elevator generally needs more than one month, and the overlong construction period has certain influence on the normal life of the owner to a certain extent.

Thirdly, the transformation range is large. Because the old district does not have elevator shaft originally, at the elevator install the in-process additional, need reform transform into the door opening that the elevator went into the family with original corridor ventilation window, still need install annex such as elevator vestibule simultaneously, this has changed original floor structure to a certain extent, produces certain influence to aspects such as old district daylighting, fire control. Meanwhile, when the elevator shaft of the outer wall is subjected to severe weather such as typhoon and the like, the stress of the wall body is influenced to a certain extent, and potential safety hazards exist to a certain extent. Old district is when installing the vertical lift elevator additional, and the elevartor shaft can change the original sewage pipes system of district, generally is through the original straight sewage pipes of 4 elbow pipe transition of 90 degrees, and this can increase the risk that the sewage pipes of old district blockked up to a certain extent. The existence of these drawbacks inhibits to some extent the need for additional elevators in old communities.

And fourthly, flat layer arrival cannot be achieved. At present, installing additional of vertical lift elevator generally is the mode of leading into the door opening through the reformation of stair ventilation window, and the elevator position of arriving at the station generally is the transition layer in the middle of the floor, floor in the middle of promptly, rather than directly getting into resident family flat bed position, and the passenger takes the elevator to arrive at the station after still need walk half the layer and just can enter one's residence, has reduced passenger elevator's use experience to a certain extent.

Secondly, analyzing the defects and contradiction points of the straight rail type escalator installed on the stair surface in the old community reconstruction:

the elevator is a new type of elevator that has appeared in recent years. The elevator is characterized in that an elevator track is fixedly arranged on a stair surface on one side close to a wall and comprises a transmission mechanism, a folding pedal, a transmission gear and the like. The rack device is arranged on the track, and the gear arranged on the transmission mechanism is mutually matched with the rack under the driving of the driving motor, so that the purpose of going upstairs and downstairs is achieved, and the problem that the old people are inconvenient to go upstairs and downstairs is solved. The elevator has the advantages of low cost, convenient and efficient installation, short construction period, small transformation range and the like, has certain application value, and has the following defects in the specific use process:

firstly, the transportation volume is small. This elevator is because of the track installation near wall one side at the stair face, has a certain amount of offsets between footboard position and the track, and passenger's focus is not in track central point, leads to the track atress uneven, therefore this elevator can only transport a passenger upstairs and downstairs at every turn, and this restricts the popularization and the use of this elevator to a certain extent.

Secondly, the floor cannot reach directly. Because the elevator can not realize the turning function, after arriving at the flat bed, the passengers need to change direction through the flat bed and then transfer another pedal. Therefore, the elevator is required to be transferred for multiple times when the elevator is taken to reach the target floor, the conveying efficiency is low, and the popularization and the application of the elevator are limited to a certain extent.

And thirdly, occupying the space of the corridor. The track of this type elevator is directly laid on the step face of stair, generally about 20 centimeters apart from the wall body, can occupy certain corridor space, and track direct mount is on the stair face, and the pedestrian when the corridor walking, appears easily because of the foot takes place to fall and hinders the problem, has certain potential safety hazard.

Thirdly, analyzing the defects and contradictions of the rotary escalator installed at the handrail part of the stair in the transformation of old districts:

this elevator is a novel elevator with the rail mounting in stair railing position, has solved better that the straight rail elevator of installing on the stair face needs to transfer in succession and the problem that can not reach that appears, has advantages such as the cost is low, installation cycle is short, has certain competitiveness, nevertheless also discovers in concrete use and has certain problem, particularly, has following not enough:

one is insufficient capacity. The elevator is installed on the side of the stair handrail, passengers stand or sit on corresponding seats to achieve the purpose of going up and down, and the bearing capacity is low due to the fact that the rails of the elevator are stressed on the sides, and the passengers cannot be transported with large transport capacity to achieve the purpose of going upstairs and downstairs. Meanwhile, the turning radius of the elevator is small, the turning speed is not smooth enough, discomfort of passengers when the passengers take the elevator is increased, and the experience of the elevator is influenced to a certain extent.

Secondly, the operation efficiency is lower. Because the turning radius of the elevator is relatively small, the necessary deceleration running is a necessary choice for enhancing the safety and the comfort of the elevator. Therefore, the low running speed limits the large-scale popularization and use of the elevator to a certain extent, and the elevator can only meet the use requirements of family old people and cannot meet the use requirements of passenger flow in old communities.

Thirdly, the transformation amplitude is relatively large. The rail of the elevator is a specially-made rail and is attached to a stair or a specially-laid support, so that the original corridor handrail needs to be modified when modification is carried out, and the special handrail matched with the rail is installed, thereby causing the problem of higher construction cost to a certain extent.

Through the analysis, the three elevators can solve the problem that the old cell is lack of elevators to a certain extent, but due to inherent contradictions and shortcomings of the three elevators, the elevator installation in the old cell is urgent, the progress is slow, the management after the elevator installation is finished is lack of definition, and the problem that the elevator installation in the old cell is poor is caused. Therefore, the novel elevator with low manufacturing cost, safety, high efficiency and large carrying capacity is provided, and the requirement is urgent.

The Chinese invention patent has the patent numbers: 201810617281.3 discloses a suspended corridor elevator, which comprises an I-steel rail device and a monorail train, and is fixedly arranged on a roof corresponding to a slope section of a stair and a roof corresponding to a stair turning platform; the monorail train comprises a series-connected railcar device, the railcar device comprises a bearing support, two sides of the upper end of the bearing support are symmetrically provided with two groups of bearing wheel sets, the bearing wheel sets are respectively clamped in a groove in the belly of the railcar device, and the lower edges of the two groups of bearing wheel sets are respectively contacted with the upper end surface of the lower flange of the railcar device and can roll on the flange; the bearing support is rotatably provided with a bearing suspension rod, and the other end of the bearing suspension rod is hinged with a manned pedal; the rail car device is provided with a driving gear, the driving gear is meshed with a transmission rack at the middle part of the lower end face of the rail car device, and a driving motor drives the driving gear to rotate. This patent structure is too simple, though has solved some current problems to a certain extent, but can not effectively solve the difficulty that the elevator transformation of old district faces, in the technique that the straight rail becomes the curved rail, does not have concrete technical scheme, can not be fine make the elevator steady change rail and operation, does not make substantive progress and breakthrough in the technique.

4. Can be reached in flat layers. Because the elevator realizes the ascending or descending transportation of passengers by arranging the tracks, if a district is 6 floors, a straight track reaching 6 floors and a semicircular track reaching 6 floors can be additionally arranged on the 6 floors, and a track reaching 6 floors can be additionally arranged on the other side of the semicircular track reaching 6 floors, so that the elevator can reach 6 floors and the aim of entering the house from the flat floors can be realized.

Compared with the existing straight rail pedal type escalator, the escalator has the following advantages:

one is the ability to run continuously. The existing straight rail pedal type escalator is characterized in that a straight rail is additionally arranged on each stair, a running motor is arranged on the straight rail to achieve the purpose of ascending and descending for passengers, after the passengers finish running on one stair, the passengers need to descend the stairs, change the stairs into a second elevator through a flat floor, and then sequentially reciprocate until reaching a target floor, so that the operation procedure is complicated, generally cannot meet the requirement of additionally arranging elevators in old communities, and is only suitable for families. The invention realizes the direct movement of floors through a dragging motor and a pre-distributed track, and solves the defect that the elevator needs continuous transfer.

Secondly, the capacity is large. Firstly, the special arrangement mode of the track of the elevator determines that the elevator has larger bearing capacity. Because the center of the track of the elevator is the middle position of the gravity center of the lift car, the elevator is stressed uniformly, the requirement on the track is reduced, and the carrying capacity is improved; secondly, this type elevator is through a towing motor, through parts such as universal connecting rod and car supporting seat, car, before the installation of elevator, can be according to the passenger flow volume that the elevator of this district took, nimble collocation car quantity, the flat bed can berth 4 footboards simultaneously, if need increase the footboard number, only need stop on the upper stair of floor with other footboards can, satisfy the needs of heavy freight volume.

Thirdly, the conveying efficiency is high. The invention adopts the flat-layer semicircular track to realize the reversing purpose, has soft turning experience, does not need to reduce the running speed of the whole elevator due to smaller turning radius, can achieve the purpose of realizing the up-down requirement of passengers by stable running speed and stable turning experience, and improves the conveying efficiency.

Compared with a curved track type pedal escalator/seat type escalator, the escalator has the following advantages:

one is the large capacity. A curved elevator is a new type of elevator in which a track is mounted near a handrail of a staircase. The elevator has the advantage of being capable of directly reaching a target floor, but the elevator is laterally stressed, so that only one passenger can be transported in the operation process of the elevator, the transportation efficiency is low, and the popularization and application of the elevator are limited to a certain extent.

Secondly, it is more intelligent. Because the operating system of the elevator is basically the same as that of the traditional vertical lifting elevator, when in operation, a target floor can be directly hit only by pressing a floor selection button in the car, and a passenger does not need to press an uplink or downlink switch by himself in the whole process, so that the operation is simpler.

Simultaneously, this elevator still has following advantage:

one is that the space occupation is small. Because the car of this elevator adopts collapsible mode, the car expandes when the passenger uses, and the car is automatic folding after leaving the car, leaves enough space for walk stair personnel, can not cause the interference to the personnel of walking on stair in the operation process of elevator. Meanwhile, after the elevator is folded, the influence on the transportation of freight is small, the elevator occupies the space of the original staircase less, and the influence on other residents is avoided.

Secondly, the noise is low. The rail wheel of the elevator is a rubber roller wheel, so that the noise of the elevator in the operation process is low, and the influence on residents is reduced.

Detailed Description

Referring to fig. 1 and 2, the basic working principle is that a track sleeper beam 74 is installed on the back surface of the stairway in the old community, and the track 8 is fixed on the track sleeper beam 74. The power transmission device 2, the car supporting seat 3 and the universal connecting rod seat body 4 are fixedly arranged on the track 8 through a positioning track wheel 43, a vertical separation type transmission shaft assembly 47 and a horizontal separation type transmission shaft assembly 48. The car 6 is connected with the car support base 3, the universal connecting rod base 4 and the power transmission device 2 are connected with each other through the universal connecting rod 7, and the car 6 performs spiral ascending or spiral descending motion around the track 8 under the driving of the power transmission device 2.

The above principle is further explained with reference to fig. 5, 6, 11, 12, 13, 15, 18 and 19: the track sleeper beam 74 is arranged on the back surface of the stair 73, the locking end of the track sleeper beam 74 is locked with the right angle of the stair step, the other side of the track sleeper beam is fixed with the wall body through an expansion screw, and the track connecting body 23 on the track 8 is arranged on the track sleeper beam 74. The track 8 is composed of a flat semicircular track 20 and a straight track 22, an arc rack 21 is arranged on the outer side of the flat semicircular track 20, and a rack 24 is arranged on the straight track 22. The junction of the straight track 22 and the flat-bed semi-circular track 20 is the overlapping area of the rack teeth, which is about 5-7 teeth. The purpose is as follows: when the gear 54 on the horizontal separation type transmission shaft assembly 48 on the power output device 2 is driven by the towing motor 39 to move up or down along the rack 24 on the straight rail 22, when the power transmission device 2 enters a flat layer at the end of the straight rail 22, the power transmission device automatically turns into the flat layer semicircular track 20, and the horizontal separation type transmission shaft assembly 48 installed on the power transmission device 2 automatically enters the rack 24 on the straight rail 22 under the driving of the gear 54, so that the direction change from the flat layer semicircular track 20 to the straight rail 22 is completed. The matching mode enables the car to turn and reverse on the premise of single row of racks and single power source. The elevator can be ensured to be uninterrupted and not to be blocked in the running process, the purpose of stable lifting is realized, and the comfort level of taking the elevator is improved. Install universal connecting rod fixed slot 45 in one side of power take off 2, fixed slot 45 cooperatees with the spheroid 56 of universal connecting rod 7, the other end of universal connecting rod 7 is connected with universal connecting rod pedestal 4, cooperate through universal connecting rod 7 at the opposite side of universal connecting rod pedestal 4, the other end of universal connecting rod 7 then is connected with universal connecting rod fixed slot 45 on the car supporting seat 3, its purpose is to realize that power take off 2 drags car 6 to realize the level turn, can steady reciprocating motion when transiting to horizontal semicircular orbit 20 by straight rail 22, single power supply drives multisection car and rises or descends simultaneously, thereby send the passenger to corresponding floor.

Referring to fig. 11, 12 and 13, when the towing motor 39 generates a forward rotation or a reverse rotation torque, the rotation torque is transmitted to the vertically separated transmission shaft assembly 47 through the bevel gear 46 and the transmission shaft 49, and the bevel gear 52 at the upper end of the vertically separated transmission shaft assembly 47 is engaged with the bevel gear 52 on the horizontally separated transmission shaft assembly 48. The gears 54 mounted on the vertically split propeller shaft assembly 47 and the horizontally split propeller shaft assembly 48 start to rotate synchronously. When the power transmission device 2 runs on the straight rail 22, the gear 54 arranged on the horizontal split type transmission shaft assembly 48 is meshed with the rack 24 on the straight rail 22, and the elevator is driven to move upwards or downwards on the straight rail 22 under the pushing of the dragging motor 39.

The gear 54 installed on the vertically-separated type propeller shaft assembly 47 is free from a rack gear on the side of the straight rail 22, thereby causing an idling phenomenon. After the power transmission device 2 reaches the position of the flat semicircular track 20, the overlapped rack with 5-7 teeth is overlapped in the connecting area of the straight track 22 and the flat semicircular track 20, so when the power transmission device 2 is transited from the straight track 22 to the flat semicircular track 20, the gear 54 arranged on the vertical separation type transmission shaft assembly 47 and the horizontal separation type transmission shaft assembly 48 is matched with the rack fixed on the straight track 22 and the flat semicircular track 20, and the transition of the power transmission device 2 from the straight track 22 to the flat semicircular track 20 is realized.

After the 5-7 teeth transition is completed, because the arc-shaped rack 21 is only arranged on the side surface of the flat-layer semicircular track 20, and no rack is arranged above the flat-layer semicircular track, the gear 54 on the vertical separation type transmission shaft assembly 47 is matched with the arc-shaped rack 21, and at the moment, the horizontal separation type transmission shaft assembly 48 is supported by the hollow track wheel 53, and the gear 54 idles. The power transmission device 2 performs flat turning under the pushing of the gear 54 on the vertically-split transmission shaft assembly 47.

When the power transmission device 2 runs to the joint of the tail end of the flat-layer semicircular track 20 and the head end of the straight track 22, the racks are arranged at the same time, and the overlapping area is 5-7 teeth. When the power transmission device 2 passes through the overlapping area, the gear 54 on the vertical separating transmission shaft assembly 47 idles, the driving force is converted into the gear 54 arranged on the horizontal separating transmission shaft assembly 48 to be matched with the rack 24 on the straight rail 22 to drive the elevator to move upwards or downwards, and the power transmission device 2 realizes the reversing from the flat semicircular track 20 to the straight rail 22.

Fig. 12 is an exploded view of the horizontal split driveshaft assembly 48 of fig. 11, and fig. 13 is an exploded view of the vertical split driveshaft assembly 47 of fig. 11. The function of the device is to transmit the kinetic energy of the dragging motor 39 to the gear 54 through the optical axis 49 while providing the supporting force for the power transmission device 2, the gear 54 driven to rotate is meshed with the arc-shaped rack on the flat semicircular track 22 and the rack 24 on the straight track 20, and the cage is driven to move upwards or downwards while the gear rotates. The working principle is as follows: the optical axis 49 is tightly matched with the bevel gear 46 and the gear 54 and can not rotate, the hollow track wheel 53 is sleeved on the outer side of the optical axis 49, two sides of the hollow track wheel 53 are fixed on the optical axis 49 through the snap springs 50, the hollow track wheel 53 can freely rotate around the optical axis 49, when the bevel gear drives the optical axis 49 and the optical axis 49 drives the gear 54 to rotate, the hollow track wheel 53 and the optical axis 49 rotate asynchronously, the number of rotation turns is related to the advancing distance between the hollow track wheel 53 and the straight rail 20 or the flat-layer semicircular track 22, and therefore when the power transmission device 2 outputs power, the rotation of the hollow track shaft 48 is not influenced by the hollow track wheel, and the purpose of synchronously realizing two functions of a single shaft is achieved.

Referring to fig. 7, 8 and 9, a cable bracket 1 and a cable collecting and distributing device 5 on a power transmission device 2 are arranged in parallel on one side, close to a wall, of a straight rail 22 and a flat semicircular rail 20, and command signals and power cables required by an elevator are distributed in the cable bracket 1 through a cable distributing contact 30. The rotating conductive slip ring 29 attached to the cable take-up device 5 converts the rotating cable on the cable winch 33 into a static cable, and supplies the static cable to the electric parts such as the floor display floor selection button 10 and the towing motor 39, thereby completing the communication and transmission of signals. When the power transmission device 2 drags the car 6 to realize ascending or descending movement, the cable laying contact 30 of the cable collecting and laying device 5 sequentially pushes the shifting lever 27 arranged on the cable bracket slot 25 to rotate towards the same direction of the movement of the power transmission device 2, after the contact 30 of the cable collecting and laying device 5 passes through the shifting lever 27, the shifting lever 27 returns to the original state under the reaction force of the return spring 26, and the laid cable is erected on the shifting lever 27 at the moment, so that the cable laying task is realized. If the elevator does reverse motion, the cable arranged on the cable bracket 1, the cable distributing contact 30 on the cable collecting and distributing device 5 can reversely push the shift lever 27 to do reverse motion, the cable is in a loose state at the moment, the shift switch 31 on the cable distributing device 5 can push the cable under the action of the return spring 34, the contact 36 on the shift switch 31 is closed at the moment, a circuit forms a loop to drive the cable collecting and distributing motor 32 to do forward motion, one end of the cable is fixed on the cable winch 33 to start to do forward rotation, and the loosened cable is sequentially tightened on the cable winch 33; after the cable is tightened, the toggle switch 31 is pressed to move reversely, the contact 36 on the toggle switch 31 is separated, the whole circuit is disconnected, the cable collecting action is stopped, and the whole cable collecting action is completed.

Referring to fig. 16, 17 and 19, the elevator car 6 is mounted on the car support base 3, the 6 positioning rail wheels 43 are respectively mounted on the car connector 59, the 6 rail wheels are closely matched with the straight rails 22 and the flat semicircular rails 20 to ensure that the car support base 3 does not shake or deflect, and the car 6 is connected with the attitude control assembly 60 at the bottom end of the car support base 3. The fixed shaft 61 is fixedly arranged at the bottom end of the car supporting seat 3, a pin part groove is formed in one end of the fixed shaft 61, a pin part on the self-locking contact 64 is matched with a pin key groove of the fixed shaft 61, so that the self-locking contact 64 can only slide left and right but can not slide rotationally, and the lower side of the car bearing shaft 11 is connected with the car 6.

The car supporting seat 3 drives the car 6 to move up and down along the straight rail 22 through the car bearing shaft 11, the car 6 drives the car bearing shaft 11 to deflect at a certain angle around the fixed shaft 61 under the action of gravity, the contact on the self-locking contact 64 is locked with the groove on the car bearing shaft 11, so that the car 6 is vertically locked at a fixed angle between the vertical direction and the horizontal plane, and the problem that the car shakes due to the shaking of passengers is solved.

When the car support seat 3 moves to the joint of the straight rail 22 and one end of the flat semicircular track 20, the car reversing contact 71 installed between the two tracks can shift the poke rod 62 installed on the car support seat 3 to deflect at a certain angle, one end of the pull rod 62 is fixed to one end of the car reversing contact, the pull cable 63 fixed to the self-locking contact 64 at the other end of the car reversing contact can drag the self-locking contact 64 to move towards the right side, at the moment, the contact on the self-locking contact 64 is separated from the groove on the car bearing rotating shaft 11, the car support seat 3 is changed from being matched with the straight rail 22 to being matched with the flat semicircular track 20, and the car 6 starts to rotate around the fixed shaft 61 installed on the car support seat 3 together with the car 6 under the action of self gravity. When the car rotates to be vertical to the horizontal plane again, the poke rod 62 surpasses the car reversing contact 71, the poke rod 62 returns to the initial state under the action of the return spring 65, at the moment, the self-locking contact 64 slides to the left under the action of the return spring and is locked with the other groove of the car bearing shaft 11, the car bearing rotating shaft 11 stops rotating, and the second reversing action is completed.

With the continuous movement of the car supporting seat 3, the poke rod 62 can be separated from the car reversing contact 71 fixed at the joint of the two rails, the poke rod 62 returns to the initial position again under the reaction force of the reset spring 65, at this time, the contact on the self-locking contact 64 is matched with a new groove on the car bearing shaft, the car 6 is locked at a new angle, and therefore the car is always kept vertical to the horizontal plane and cannot deflect and shake.

The power transmission device 2, the car supporting seat 3 and the universal connecting rod seat body 4 are connected through the universal connecting rod 7 in sequence, and a certain distance is kept between every two of the power transmission device, the car supporting seat and the universal connecting rod seat body to be connected to the track 8. When the elevator descends, the power transmission device 2 transmits power to each section of car in sequence through the universal connecting rod 7, the car supporting seat 3 is pushed to drive the car 6 to reversely descend on the horizontal semicircular track 20, the problem that the tail car 6 stops running due to the loss of gravity at the flat bed position is prevented, and the ascending and descending of the car can be completed through a single power source.

Referring to fig. 3 and 4, the car is provided with an upper folding joint 12, a middle folding joint 13 and a folding pedal 15. The length of the upper folding joint 12 is similar to that of the folding pedal 15. The connection parts of the folding pedal 15, the car upright post 17 and the lower folding upright post 77 are provided with 4 hinges which can rotate freely. When the passenger gets off the elevator, the upper folding joint 12 is under the action of the return spring or the driving motor, the upper folding upright post 76 is folded inwards, the middle folding joint 13 starts to rotate, and the lower folding upright post 77 is driven to be connected with the pedal and folded inwards. When the upper folding joint 76 is folded to be parallel to the horizontal plane, the folding step 15 and the lower folding column 77 are in an upright state, and at this time, the car is folded.

Referring to fig. 14, the universal connecting rod 7 is composed of a spherical body 56 and a connecting rod 57. Spherical body 56 is connected with power transmission device 2, car supporting seat 3, universal connecting rod fixed slot 45 on the universal connecting rod pedestal 4 respectively, just so can guarantee that power transmission device 2, car supporting seat 3, universal connecting rod pedestal 4 move steadily when passing through flat bed semicircular track 20, flat bed semicircular track 20 and straight rail 22 handing-over department, prevents the emergence of the inhomogeneous phenomenon of orbit.

Referring to fig. 18, the track bolster 74 includes a set screw hole 66, a bolster body 67, and a clamp head 68. The clamp 68 is a right-angle clamp with a length of about 5-10 cm, the installation position is that the right-angle position of the front step of the stair 73 forms tight fit, and the width of the track sleeper beam 74 is basically the same as the width of the stair surface. The installation method comprises the following steps: after the clamping head 68 is clamped into the right-angle step of the stair 73, the sleeper beam main body 67 is attached to the back of the stair 73, and the positioning screw hole 59 is fixed with the wall body through an expansion screw, so that the rail sleeper beam 74 can be guaranteed to have larger bearing capacity, and normal walking of pedestrians from the stair surface is not influenced.

Referring to fig. 20, fig. 20 is a diagram of the operating posture of the pedals when the elevator is simulated to make a turn on a flat floor. The length of the pedal is about 50cm, the width of the pedal is about 30cm, and the radius of the flat semicircular track is about 50 cm. In this state, 4 cars can complete the turning action at the same leveling position. The problem that every two vertex angles of the car touch in the turning process can not be simulated through the graph. If the number of the cages needs to be increased continuously, the two cages are arranged at the same interval.

Referring to fig. 21, fig. 21 is a logical operation diagram of an elevator. The working principle is that when someone presses the upper and lower floor selection button 70 on any floor, the signal is sent to the elevator electrical control system, the elevator electrical control system sends the selection instruction to the logic control and distribution circuit, and the running direction of the elevator is judged according to the floor where the elevator is located at that time. If the button that the passenger pressed at floor 3, the elevator was at floor 1, and logic control circuit then judges that the motor needs the forward rotation this moment, after judging, sends command signal to the motor that drags through the safety circuit, drags the motor forward rotation, goes upward the operation. When the power transmission device 2 reaches the leveling floor, the leveling floor signal is sent to the elevator control system, the elevator electrical control system judges that the motor needs to stop running, the stop signal is sent to the towing motor, and the towing motor stops rotating after receiving the instruction, so that the elevator arrives at the station. After the elevator arrives at a station, passengers board the elevator, press the floor selection button 10 of floor 1, the floor selection button 10 will send the floor signal to be reached to the electrical control system of the elevator, the electrical control system of the elevator sends the signal to the logic control and distribution circuit, according to the logic relation from floor 3 to floor 1, judge that the motor needs to move in reverse direction, and send the electrical signal to the towing motor 39 through the protection circuit, the towing motor 39 after receiving the instruction starts to move in reverse direction, the power transmission device 2 drives the car to move downwards, when the elevator arrives at floor 1, the floor arrival signal will be sent to the electrical control system of the elevator, after receiving the floor signal, the electrical control system of the elevator will transmit a stop instruction to the towing motor, the towing motor 39 after receiving the instruction will stop rotating, finish the descending action, and finish the transportation process of one passenger.

The elevator electrical control box 69 is installed on the middle floor of each building, so that the cable length is saved, and the purpose of controlling the operation of the elevator can be realized only by twisting half of the cable winch 5.

Rubber layers are distributed on the outer layers of the positioning track wheels 43 and the hollow track wheels 53, so that when the elevator runs, noise among the positioning track wheels 43, the hollow track wheels 53 and the track 8 is reduced, and the quietness of the elevator during running is improved.

Because the stairway of the old community only reaches the flat position of the 6 th floor, the elevator can not continuously reach the 6 th floor or other top floors through the installation of the track sleeper beams 74. In order to achieve the aim of reaching 6 floors or other highest floors of the elevator, 1 extending track beam 78 (shown in figure 22) to 6 floors and half of 6 floors is additionally arranged on the 6 floors or other highest floors, one end of each extending track beam 78 is connected with the 6-floor flat semicircular track 20, the other end of each extending track beam 78 is connected with the 6-floor semicircular track 20, the other end of each semicircular track 20 is connected with one end of the second extending track beam 78, and the other end of each extending track beam 78 is fixed at the roof 79 of the top floor. The purpose of this is to arrange the rails at the attic position by adding the extension rail beam 78 and installing the rails 8 below the extension rail beam 78, and finally to achieve the purpose of flat-bed landing.

The structure also has the following safety protection measures:

first, fig. 10 is a circuit protection device. The working principle is as follows: when the elevator car 6 is in a folded state, the car fixed side contact 41 touches the car upright post 17 of the car 6, the contact 41 on the double control switch 38 is pressed, the circuit is switched on, and at the moment, the dragging motor 39 is switched on, so that the elevator running purpose of the elevator in the folded state is realized. When the passenger presses the up/down selection key, the towing motor 39 can normally perform the up and down operation. When a passenger needs to take the elevator, the elevator car 6 is opened, the contact 41 on the double-control switch 38 loses extrusion at the moment, the whole circuit is disconnected under the action of the reset spring in the double-control switch 38, at the moment, no matter other floors press the upper and lower floor selection buttons 70 or the passenger presses the floor selection button 10, the whole circuit is in a disconnected state, and the dragging motor 39 does not work, so that the elevator does not run before the unfolding action of the elevator is finished, the static state is kept, and the accidental injury of personnel is prevented; when the elevator car 6 is completely unfolded, passengers enter the car, the elevator circuit is still in an open circuit state at the moment and cannot go upwards or downwards, the passengers need to pull the handrail 14, the handrail 14 moves circularly around the folding handrail fixing seat 40, the lower end of the handrail 14 presses the contact 42 on the double-control switch 38 to act, the double-link switch 38 is triggered at the moment, the whole circuit is switched on, and after the passengers press the floor selection button, the elevator moves upwards or downwards according to the set floor. The elevator safety when many people share the elevator can be guaranteed through the scheme.

Two, both sides around the folding footboard 15 of car 6, install infrared switch 19, one side of folding footboard is infrared light source, the opposite side is the reflecting plate, it is timely to touch with footboard 15 front and back side when passenger's limbs or foreign matter are unexpected, infrared reflecting plate can not reflect the infrared light, whole circuit disconnection this moment, thereby guarantee that the car meets the barrier at the in-process of marcing, or elevator stop motion when passenger's accident contacts with footboard 15 outer fringe, thereby prevent the extrusion danger that takes place, with this guarantee the safety of elevator at the in-process of marcing.

Thirdly, each car supporting seat 3 is provided with an overspeed locking device. When fracture appears in universal connecting rod 7, or when parts such as power transmission device 2, car supporting seat 3, universal connecting rod pedestal 4 appear damaging beyond, whole elevator can lock in the twinkling of an eye, prevents to appear breaking away from the emergence of phenomenon because of the accident because of a certain section car, guarantees elevator operation safety.

Fourthly, establish ties mutually through the steel cable on power transmission device 2, car supporting seat 3, universal connecting rod pedestal 4, and its purpose is when universal connecting rod 7 fracture or other unexpected circumstances appear, and the car still can be connected each other, guarantees in proper order not to appear the swift current rail phenomenon.

And fifthly, a tension sensor is arranged on each car supporting seat 3, when the load of the car exceeds a specified value, the whole circuit is in a disconnected state, and an alarm is given to remind passengers of forbidding overload.

And sixthly, a front and rear folding fence 18 is arranged on each car. One side of the folding enclosure 18 is connected with the car upright post 17 through a joint, the other side is hollow in the middle, and the hollow part slides around the lower folding upright post 77. The purpose is that when the car is in an unfolded state, the fixing points of the front and rear folding enclosure 18 and the lower folding upright post 77 slide along the hollowed-out tracks, and the other side of the front and rear folding enclosure and the car upright post 17 do circular motion and are slowly unfolded, so that the front and rear shelters for passengers when taking the elevator are ensured, and the safety of the passengers is ensured. When passengers get off the elevator, the folding rod of the elevator car can be automatically folded under the action of the return spring.

The specific operation method of the invention is as follows:

when passengers on any floor need to go upstairs and downstairs, the passengers press the up-down selection button to call the elevator. After receiving the instruction, the elevator automatically judges whether the elevator needs to move upwards or downwards according to the logic relation. When the elevator runs to the floor where the passenger is located, the elevator automatically stops running and is in a passenger-waiting state, and at the moment, the elevator car is in a folded state. At the moment, the passenger orders the elevator to automatically unfold in a card swiping mode. After the lift car is completely unfolded, passengers enter the lift car, the folding handrails are closed, and at the moment, the circuit is in a state to be operated. And then, the passenger presses a button of the floor to be reached, after receiving the instruction, the elevator automatically judges whether the elevator ascends or descends, and after reaching the target floor, the elevator automatically stops running.

Upon arrival at the destination floor, the passenger opens the folding armrest 14, and the circuit is in a power-off state. When the passenger leaves from the car, the folding pedal 15 is automatically folded under the driving of a return spring or a motor installed in the upper folding joint 12. Before the folding pedal 15 is completely folded, the duplex switch is in a disconnected state, the whole elevator is in a load stop state at the moment, and the whole elevator is in a stop running state no matter how other floors press the floor selection buttons or other car passengers press the floor selection buttons, so that the elevator is ensured to be in the stop state in the folding process.
