Description

Broken chain detection device of light escalator chain Technical Field The application relates to the technical field of escalators, in particular to a broken chain detection device of a light escalator chain. Background An escalator is a stationary electrically driven device with endless moving steps for transporting passengers obliquely upward or downward. The prior patent (publication number: CN 101643178A) discloses an escalator with a broken chain detection device, which can timely control a host machine to stop when a step chain is broken, so as to avoid personnel injury and damage to escalator parts. The device comprises a step chain track, wherein a step chain is arranged in the step chain track, and a detection sensor is further arranged in the step chain track, wherein the detection sensor is positioned below the step chain. Above-mentioned staircase detects the chain of staircase through detecting the sensor to the effect that makes the host computer of staircase park when reaching the broken chain, but detect the sensor and only play the guard action when the broken chain, can't monitor the running state of chain, can't in time acquire the deformation of chain, circumstances such as damage, and then can't in time maintain the chain before the broken chain, the emergence of prevention broken chain condition exists certain improvement space. Disclosure of utility model Aiming at the defects of the prior art, the application provides a broken chain detection device of a light escalator chain, which is provided with the advantages that the running state of the chain can be monitored, the deformation, the damage and other information of the chain can be timely obtained, the chain can be timely maintained, the broken chain condition can be effectively prevented, the continuous normal running of the escalator can be ensured, and the like, and the problems that the existing escalator can only play a role in stopping protection when the chain is broken, the running state of the chain can not be monitored, the deformation, the damage and other conditions of the chain can not be timely obtained, the chain can not be timely maintained before the chain is broken, and the broken chain condition can be prevented are solved.
