Problems solved by technology

Therefore, even if the braking characteristics at the time of installation are changed due to subsequent operation, it is difficult to detect abnormalities in the braking characteristics as long as the latter braking characteristics meet the prescribed standards.
That is, it is difficult to evaluate braking characteristics over time

Abstract

The invention provides a maintenance system for a brake device of an elevator, which can save labor for maintenance operation of the brake device and can reliably maintain brake performance of the brake device. The brake device maintenance system for elevator provided by the invention includes a detection unit, which is equipped on an counterforce exerting unit of the brake device for detecting aregulated distance for a friction member separated from a brake body. Furthermore, the counterforce exerting unit and the detection unit are connected with the control unit, and the control unit transmits a brake releasing demand signal to the counterforce exerting unit, and receives a friction member departing signal from the detection unit. The control unit figures out a brake releasing time during setting and a brake releasing time during maintenance according to the brake releasing demand signal and the friction member departing signal, and the difference between the a brake releasing time during setting and a brake releasing time during maintenance is used for judging whether the clearance between the friction member and the braked body is normal.

Description

technical field [0001] The present invention relates to an elevator braking device inspection system for inspecting the elevator braking device, and more particularly to an elevator braking device capable of saving labor in the inspection work of the braking device and reliably maintaining the braking performance of the braking device. Moving device maintenance system. Background technique [0002] In the past, there is known such a brake device, which has: a braked body mounted on the rotating shaft of the elevator hoist; a friction member freely contacting with the braked body; an urging unit of a member; an opposing force applying unit that applies a force against the urging force of the urging unit to the friction member to the friction member. [0003] In the case of overhauling such a braking device, the gap (gap) between the braked body and the friction member, the wear state of the friction member, and the braking torque generated when the brake is activated are che...
