Abstract

The invention discloses an iron chain breaking strength detection device which comprises two opposite fixing seats, wherein two opposite clamping plates are fixedly connected between the two fixing seats; certain space is reserved between the two clamping plates; a chain ring of a compensation chain is clamped in the gap between the two clamping plates for fixing, and then the compensation chain is stretched so as to detect whether the stretched compensation chain has pseudo soldering or solder skips; after the stretching, the chain ring is taken out of the gap between the two clamping plates,without needing other fixing structures; therefore, the stretching efficiency of the compensation chain is improved, and the problems of pseudo soldering and solder skips of the compensation chain and consequent influence on the elevator running safety can be solved.

Description

technical field [0001] The present disclosure generally relates to the field of elevators, specifically to the field of detection of compensation chains, and in particular to a detection device for breaking strength of iron chains. 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. The str...
