Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in an elevator suspension chain swaying device.

[Background of the invention]

First, a conventional anti-sway device will be explained with reference to FIGS. 4 and 5.

In the figure, 1 is the elevator hoistway, and 2 is the drive machine.

3 is the main rope wrapped around this, 4 is a cage, and 5 is a counterweight, each of which is suspended from both ends of the main M3. ,
6 is a suspension chain whose both ends are suspended from the car 4 and the counterweight 5, respectively; 7 is a swaying body disposed across the loop at the lower end of the suspension chain 6, which is made of resin and has a crosspiece 7a inserted therethrough; It is composed of a swing stopper 7b. 8 is a guide rail erected on the hoistway 1, 9 is fixed to this via a rail clip 10 and protrudes, and a crosspiece 7 is attached to the protruding end.
The end of a is a fixed arm that is fastened.

That is, the anti-sway body 7 is supported at a predetermined position within the hoistway 1 by the fixed arm 9. When the car 4 and the counterweight 5 are raised and lowered alternately, the balance chain 6 moves in a loop at the bottom, and the movement of the balance chain 6 causes shaking, so this shaking is limited to a predetermined range. For this reason, the anti-sway body 7 is provided. The amount of wear on the sway stopper 7b is proportional to the elevator running time.When the sway stopper 7b becomes subject to severe sliding wear and the sway stopper 7a is exposed inside the sway stopper 7b, the balance chain 6 and the sway stopper become damaged. 7a rubs against each other, producing abnormal noises and causing a sense of unease not only to the customers but also to the residents. Replacement of the anti-sway member 7b involves removing the anti-sway body 7a from the fixed arm 9 and replacing it, which takes a lot of time. (Practical No. 56-140571) [Object of the Invention] An object of the present invention is to provide a balance chain swaying device that allows the swaying element to be replaced in a short time without removing the swaying body. .

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

7C is a swing stopper in which a spiral cut 7d is added to the swing stopper 7b. That is, since the anti-sway element 7c has a spiral cut, the anti-sway element 7c can be attached while being rotated so as to be wrapped around the anti-sway body 7a as shown in FIG. 2, and can be removed without removing the anti-sway body 7a. Can be replaced.

FIG. 3 shows another embodiment of the present invention, in which 7C is a swing stopper whose notch shape is changed, and both ends of the swing stopper 7C are tied with 11 to prevent it from falling.

Further, 7c is a device in which the swing stopper is cut in the longitudinal direction and divided into two or more parts, which are attached to the swing stop body 7a and then tied together, and even in this case, it can be replaced without removing the swing stop body 7a. It goes without saying that there are a wide variety of ways to cut the vibration stopper 7b.

That is, in the embodiments shown in FIG.
Similar to the embodiment shown in FIGS. 2 and 2, the anti-sway body 7a can be replaced without being removed.

〔Effect of the invention〕

According to the present invention, the balance chain sway stopper can be replaced without removing the balance chain sway stopper, and the work that used to take a lot of time can be done in a short time.

Claims (1)

[Claims] 1. A balance chain whose both ends are suspended from a car and a counterweight that alternately move up and down the hoistway, forming a downward curved line, and which is disposed across the curved line of this chain. and an elevator suspension chain having a swaying body supported by a fixed body in the hoistway, wherein a swaying element that covers the swaying body is detachably attached to the swaying body. Device.
