Embodiment mode 1

Fig. 1 is a configuration diagram of an elevator system to which a counterweight of an elevator in embodiment 1 is applied.

In the elevator system of fig. 1, a hoistway 1 extends through each floor of a building. A plurality of landings 2 are provided at each floor of the building. Each of the landings 2 faces the hoistway 1. Each of the plurality of landings 2 has a landing door 3.

The hoisting machine 4 is provided at an upper portion of the hoistway 1. The hoisting machine 4 has a sheave 5. The deflector pulley 6 is provided at an upper portion of the hoistway 1.

A pair of car guide rails 7 are provided in the hoistway 1. The pair of car guide rails 7 extend in the vertical direction. A pair of car guide rails 7 are parallel to each other. The pair of car guide rails 7 face each other.

A pair of counterweight guide rails 8 are provided in the hoistway 1. The pair of counterweight guide rails 8 extend in the vertical direction. A pair of counterweight guide rails 8 are parallel to each other. The pair of counterweight guide rails 8 are opposed to each other.

The main ropes 9 are wound around the sheave 5 and the deflector sheave 6.

The car 10 is supported by one side of the main rope 9. The car 10 is provided so as to be able to ascend and descend along a pair of car guide rails 7 inside the hoistway 1. The car 10 has a car door 11.

The counterweight 12 is supported on the other side of the main rope 9. The counterweight 12 is provided so as to be able to ascend and descend along the pair of counterweight guide rails 8 inside the hoistway 1. The counterweight 12 has a counterweight frame 13 and a plurality of counterweight blocks 14.

The car buffer 15 is provided at the bottom of the hoistway 1. The car buffer 15 is provided below the car 10.

The counterweight buffer 16 is provided at the bottom of the hoistway 1. The counterweight buffer 16 is disposed below the counterweight.

Next, a method of moving the weight 14 will be described with reference to fig. 2.

Fig. 2 is a front view of a counterweight to which a counterweight of an elevator in embodiment 1 is applied.

As shown in fig. 2, the hoist rope 17 hoists the main body portion 14a while penetrating a hole portion 14b formed closer to one end side than the center portion of the main body portion 14a of the weight 14. As a result, the weight 14 is stably lifted obliquely so that one end side thereof is positioned above. In this state, the counterweight 14 is attached to the counterweight frame 13 in a state where both end portions of the main body portion 14a are guided by a pair of grooves, not shown, formed in the counterweight frame 13.

These steps are sequentially repeated for each of the plurality of pairs of weights 14. A plurality of counter weights 14 are stacked in the vertical direction.

Next, the weight 14 will be described with reference to fig. 3 to 6.

Fig. 3 is a perspective view of counterweight blocks of the elevator in embodiment 1. Fig. 4 is a front view of a counterweight block of the elevator in embodiment 1. Fig. 5 is a plan view of counterweight blocks of the elevator in embodiment 1. Fig. 6 is a side view of the counterweight bodies of the elevator in embodiment 1.

As shown in fig. 3 to 6, in the counterweight body 14, the hole portion 14b is formed from one of the proximal side and the distal side of the upper surface of the body portion 14a toward the other of the proximal side and the distal side of the lower surface of the body portion 14 a. As a result, the weight 14 is stably lifted obliquely in the depth direction of the body portion 14a by the lifting rope 17 not shown in fig. 3 to 6.

The hole 14b may be formed to be inclined toward the center of the body 14a in the depth direction on the one end of the weight 14. For example, the hole 14b may be formed so as to be closer to the one end side of the body 14a from the upper surface side of the body 14a toward the lower surface side of the body 14 a. For example, the hole 14b may be formed so as to be closer to the opposite side of the one end side of the body portion 14a from the upper surface side of the body portion 14a toward the lower surface side of the body portion 14 a.

The hole 14b may be formed on the one end of the counter weight 14 so as to be inclined with respect to the depth direction and the width direction of the body portion 14 a. For example, the hole 14b may be formed so as to be closer to the distal side of the body 14a and to the one end side of the body 14a from the front side of the body 14a as going from the upper surface side of the body 14a to the lower surface side of the body 14 a. For example, the hole 14b may be formed so as to be closer to the front side of the body 14a from the far side of the body 14a and to be closer to the opposite side of the one end side of the body 14a as going from the upper surface side of the body 14a toward the lower surface side of the body 14 a. For example, the hole 14b may be formed so as to be closer to the front of the body 14a from the far side of the body 14a and closer to the one end side of the body 14a as going from the upper surface side of the body 14a toward the lower surface side of the body 14 a. For example, the hole 14b may be formed so as to be closer to the far side of the body 14a from the near side of the body 14a and to be closer to the opposite side of the one end side of the body 14a as going from the upper surface side of the body 14a toward the lower surface side of the body 14 a.

Next, a method of stacking a plurality of counter weights 14 will be described with reference to fig. 7.

Fig. 7 is a diagram for explaining a method of stacking a plurality of counterweight bodies in the elevator according to embodiment 1.

As shown in fig. 7, when the plurality of counterweight blocks 14 are stacked, the hole portions 14b of the plurality of counterweight blocks 14 are alternately arranged at a position close to one side of the counterweight frame 13 and a position close to the other side of the counterweight frame 13.

According to embodiment 1 described above, the hoist rope 17 lifts the main body portion 14a while penetrating the hole portion 14b formed in the main body portion 14a of the counterweight 14. Therefore, the counterweight 14 can be easily moved.

The hole 14b is disposed closer to one end side than the center of the body 14 a. Therefore, the counterweight 14 can be stably moved.

Further, the hole portion 14b is formed from one of the proximal side and the distal side of the upper surface of the body portion 14a toward the other of the proximal side and the distal side of the lower surface of the body portion 14 a. Therefore, the counterweight 14 can be moved more stably.

The hole portions 14b of the weights 14 are alternately arranged at a position closer to one side of the counterweight frame 13 and a position closer to the other side of the counterweight frame 13. Therefore, the weight deviation in the width direction of the counterweight 12 can be suppressed.

Embodiment mode 2

Fig. 8 is a side view showing a state of lifting a counterweight of the elevator in embodiment 2. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.

The counterweight 14 of embodiment 2 has a protrusion 14 c. The protrusion 14c is integrally provided to one of the proximal side and the distal side of the main body. The hole 14b is formed to penetrate the protrusion 14c in the vertical direction.

The hoist rope 17 is wound around the main body while passing through the hole portion 14b of the counterweight 14. In this state, the hoist rope 17 lifts the counterweight 14.

According to embodiment 2 described above, the hoist rope 17 lifts the counter weight 14 while penetrating the hole portion 14b of the protruding portion 14c provided on one of the near side and the far side of the main body portion 14a of the counter weight 14. In this case, the counterweight 14 can be easily moved.

When a plurality of counter weights 14 are stacked, the protrusions 14c of the plurality of counter weights 14 may be alternately arranged on the front side and the far side of the counterweight frame 13. In this case, the weight shift in the depth of the counterweight 12 can be suppressed.

Note that the plurality of counterweight blocks 14 according to embodiment 1 or embodiment 2 are also lifted when removed from the counterweight frame 13. Therefore, the counterweight 14 can be easily removed from the counterweight frame 13.

Industrial applicability

As described above, the counterweight block of an elevator and the method for moving the same according to the present invention can be used in an elevator system.
