A Drive Chain Break Detecting Device For An Escalator and A Sub-brake Control System For An Escalator

摘要

The present invention relates to an auxiliary brake control system for a horizontal walker. An auxiliary brake control system for a moving walk according to the present invention includes a drive chain break detection device for monitoring a load of a motor vehicle traveling in a horizontal walk and detecting the occurrence of breakage of the drive chain from a change in the motor load; An auxiliary brake for performing disc braking by applying an actuator lining pressure when a break of the drive chain is detected by the drive chain breaking detection device; The controller detects the motor load of the moving walk of the drive chain broken or detected by the drive chain breakage detecting device to calculate the operating pressure of the auxiliary brake actuator corresponding to the braking distance, and adjusts the actuator lining pressure of the auxiliary brake And an auxiliary brake control means for controlling the auxiliary brake.
