Guide device for balance compensation chain of elevator

Abstract

The invention provides a guide device for a balance compensation chain of an elevator. The guide device mainly comprises a mounting part, a connecting part and a guide part; the balance compensation chain is located in a closed space formed by the guide part; the guide part is rigidly connected to the connecting part; the connecting part is connected to the mounting part through a hinge, can rotate around the mounting part and and can be automatically restored to the initial position; the connecting part can be retractable and can be automatically restored to the initial length; and rolling wheel parts are arranged on the guide device and have the buffering function. According to the guide device, when the balance compensation chain operates normally, the guide device does not make contact with the balance compensation chain, when the balance compensation chain shakes violently, the collision strength with the balance compensation chain can be buffered, noise and vibration of the elevator in the operation process can be reduced, in addition, damage to surface flexible materials by the guide device can be reduced, the friction resistance when the balance compensation chain makes contact with the guide device can be reduced, and the operation load and the potential safety hazards of the elevator can be reduced.

Description

technical field [0001] The invention relates to the technical field of a balance compensation chain of an elevator, in particular to a guide device for an elevator balance compensation chain. Background technique [0002] When the elevator is running, the car of the elevator is connected to the counterweight on the opposite side through the steel wire rope. When the car is on the top floor, the steel wire rope is on the counterweight side, and the weight of the steel wire rope is on the counterweight side; when the car is on the bottom floor, the steel wire rope Just on the side of the car, there is more weight of the steel wire rope on the side of the car. The steel wire rope moves up and down with the elevator, which will produce a dynamic imbalance. Therefore, it is necessary to use a compensation chain to compensate the weight of the steel wire rope to balance this part of the drop, so that the elevator Smooth operation; at present, in elevators with a vertical lifting d...

Problems solved by technology

[0004] In order to overcome the following problems in the prior art: when the sway of the balance compensation chain is relatively large, the rigid guide device will have a relatively large hard collision with the balance compensation chain, which will generate more collisions, noise and vibration, and damage the balance compensation chain. Or the guide device, and the collision between the rigid guide device and the balance compensation chain will damage the flexible material on the surface, increase the friction resistance when the balance compensation chain and the guide device contact, damage the balance compensation chain or the guide device itself, and cause safety hazards; The invention provides a guide device for an elevator balance compensation chain, mainly comprising: an installation part, a connection part and a guide part, the installation part and the connection part are connected by a hinge, and the connection part and the guide device are rigidly connected
