Brake static torque measuring device and passenger static torque measuring method for passenger conveyor

摘要

A brake static torque measuring apparatus for an escalator capable of separately measuring the static torque of each brake of a plurality of drive units is obtained.The brake static torque measuring device of this escalator isA control device for driving respective motors in a plurality of drive units and controlling the operation of each brakeA slip detector for detecting a brake slip andA torque measuring section for measuring torque generated in the motor is provided.Control deviceSelect one brake for multiple drive unitsThe state of the selected brake is in the braking state.The state of all other brakes except for the selected brake is releasedDrive all motors in multiple drive unitsControl deviceWhen the slip detector detects the slip of the brake, the torque generated in the motor to be measured by the torque measuring portion is assumed to be static torque.
