ACTION STATE DETECTION APPARATUS AND DETECTION METHOD FOR ELEVATOR BRAKE

摘要

An action state detection apparatus and detection method for an elevator brake. An elevator brake comprises a pressure sensor (10) for detecting the value of a pressure between a braking shoe (8) and a braking wheel (14), or a pressure sensor (10) for detecting the value of a pressure between an adjusting bolt (5) and an iron core (4), so as to realize the real-time direct monitoring of an action state of the brake, such that the defects of an existing monitoring apparatus, such as having wearing processing of the braking shoe (8), a braking clearance that is too small and not easy to adjust, elevator operation vibration processing, a fixation mode unable to be embedded, the fixation being unreliable, and the mounting and adjustment being affected by human factors, etc. are overcome. The existing problem of asynchronization that may occur between the monitoring element used and an actual braking state is effectively avoided, the problem of false positives or failures of the monitoring apparatus used is solved, and the safety of the elevator is improved.
