DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator counterweight device suspended by a plurality of main ropes provided in parallel.

[0002]

2. Description of the Related Art For example, as shown in Japanese Utility Model Application Laid-Open No. 58-71060, a car is provided on a hoistway, and a counterweight is disposed between the car and the peripheral wall of the hoistway. And
The car and the counterweight are connected by a plurality of main ropes provided in parallel to form a traction-type elevator.

[0003] In the elevator as described above, the main ropes are driven, and the car and the counterweight move up and down in the hoistway in mutually opposite directions. Then, in order to equalize the tension of each of the main ropes, the tension is adjusted via a nut of a stopper at the end on the counterweight side in a timely manner.

[0004]

In the elevator as described above, the nuts of the stoppers are arranged at the same position in the vertical direction. In this arrangement, the detent arranged near the peripheral wall of the hoistway is hidden by the detent arranged near the car, so that the adjusting operation becomes difficult. Therefore, there is a problem that much work time is required for leveling the tension of the main rope, and leveling becomes coarse.

[0005] The present invention has been made to solve such a problem, and an object of the present invention is to provide an elevator counterweight device capable of easily leveling the tension of a plurality of main ropes.

[0006]

According to the present invention, there is provided an elevator counterweight device having a front connecting portion near the front of the counterweight and a rear connecting portion below the front connecting portion near the rear. Provided.

[0007]

The nut of the retaining member of the main rope connected to the rear connecting portion of the elevator balancing weight device constructed as described above is disposed below the retaining member of the main rope connected to the front connecting portion. Is done.

[0008]

Embodiment 1 FIGS. 1 and 2 show an embodiment of the present invention.
Reference numeral 1 denotes a hoistway having a peripheral wall 1a, 2 denotes a counterweight for elevating the hoistway 1, and 2a denotes a front surface of the counterweight 2 formed from the side opposite to the peripheral wall 1a, and 2b denotes a rear surface of the counterweight 2 facing the peripheral wall 1a. Reference numeral 2c denotes a front connecting portion of the counterweight 2 and 2d denotes a counterweight 2 provided below the front connecting portion 2c.
The rear connecting portion 3 is erected on the hoistway 1 and has guide rails erected on both sides of the counterweight 2, and 4 is fixed to the four corners of the counterweight 2 and can be moved to the guide rail 3. 5 is a main rope, 6 is a stopper fixed to the end of the main rope 5, respectively, is inserted into the front connecting portion 2c or the rear connecting portion 2d, and a nut 6a is inserted at the insertion end. Screwed.

[0009] In the elevator weight assembly device constructed as described above, some of the retaining members 6 of the plurality of main ropes 5 are connected to the front connecting portion 2c, and the other retaining members 6 are connected to the rear side. It is connected to the connection part 2d. As a result, the nut 6a of the stopper 6 connected to the rear connecting portion 2d is disposed below the stopper 6 connected to the front connecting portion 2c. Therefore, the nut 6a of the rear connecting portion 2c for adjusting the tension of the main rope 5 can be easily operated from the center side of the hoistway 1. Therefore, the work time for tension leveling can be shortened, and highly accurate tension leveling can be achieved.

[0010]

As described above, according to the present invention, some of the retaining members of the main ropes are connected to the front connecting portion of the counterweight, and the other retaining members are located below the front connecting portion. It is connected to the rear connection part of the provided counterweight.
Thereby, the operation of the nut of the stopper connected to the rear connecting portion can be easily performed from the hoistway center side, and there is an effect that the work for equalizing the tension of the main rope is made more efficient.
