Problems solved by technology

[0003] The existing compensation chain is fixed at the fixed end by using the connecting buckle to the bottom beam of the car or the bottom of the counterweight frame. During the operation of the elevator, the compensation chain may be twisted, and the connecting buckle cannot be rotated, which may easily cause damage to the connecting buckle. , leading to tripping of the compensation chain, resulting in safety accidents

Abstract

The invention discloses a fixing device for a compensation chain and the compensation chain. The fixing device for the compensation chain comprises a fixed barrel, wherein a turntable bearing is connected into the fixed barrel in a sliding manner, the turntable bearing slides in the axial direction of the fixed barrel, a fixed rod is fixedly connected into an inner ring of the turntable bearing, acheck ring is arranged at one end of the fixed barrel, a through hole is formed in the check ring, and the diameter of the through hole is smaller than the outer diameter of the turntable bearing; and the compensation chain comprises a compensation chain body and the fixing device for the compensation chain, and a non-end chain link of the compensation chain body penetrates through the through hole to be fixedly connected with the fixed rod. The influence of the torsion of the compensation chain on the fixed tube in an elevator operating process is reduced, and the probability that the compensation chain is separated from the fixed rod is reduced.

Description

technical field [0001] The present invention generally relates to the field of elevators, specifically to the field of elevator safety, and in particular to a fixing device for a compensation chain and a compensation chain. Background technique [0002] When the lifting height of the van elevator exceeds 30 meters, it is necessary to use the compensation chain. Because when the elevator is on the top floor, the steel wire rope is on the counterweight side, and the weight of the steel wire rope is added to the counterweight side; when the elevator is on the bottom floor, the steel wire rope is on the car side, and the weight of the steel wire rope is added to the car side. Due to the weight of the steel wire rope, as the elevator moves up and down, dynamic imbalance will be generated. Therefore, the compensation chain can be used to balance this part of the drop, which is used to compensate the weight of the steel wire rope and make the elevator run smoothly. [0003] The ex...
