Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an elevator compensating chain guide device. Background Art

[0002] During the use of the elevator, a compensation chain is needed to compensate for the weight of the wire rope. In vertical lifts, the compensation chain is an important device to ensure the stability and safety of the elevator operation, so that the elevator can run smoothly. As the elevator moves up and down, the weight of the elevator changes continuously, which will produce dynamic imbalance. The compensation chain is used to compensate for this imbalance. When the elevator is overloaded or out of control, the elevator compensation chain and the guide device work together to protect the elevator.

[0003] However, the ordinary elevator compensating chain guide device cannot adjust the position of the guide wheel when in use, and the guide is not stable enough. Therefore, we propose an elevator compensating chain guide device. Utility Model Content
