Disc Hydraulic Caliper Type Safety Brake Control Apparatus for Emergency Stop of Escalator for Heavy Load

摘要

The present invention relates to a disc hydraulic caliper emergency stop safety brake control device for a high load escalator, the reverse rotation sensor for sensing the rotation direction of the rotating shaft of the escalator; An overspeed detection sensor for detecting a rotational speed of the escalator rotation shaft; An emergency stop safety brake for blocking rotation of the escalator rotation shaft with a mechanical force; And a controller for controlling an emergency stop safety brake by determining whether an abnormality occurs according to signals of the reverse rotation detection sensor and the overspeed detection sensor. The emergency stop safety brake includes a brake disc additionally installed on an escalator rotating shaft, and a hydraulic caliper which limits the rotation of the brake disc by simultaneously applying pressure on both sides of the brake disc and operates by a signal from the controller. The brake is provided so as to correspond to the center side portion of the escalator rotation shaft so as to brake the center side portion of the escalator rotation shaft.
