HYDRAULIC SAFETY BRAKE CONTROL APPARATUS FOR EMERGENCY STOP OF ESCALATOR FOR HEAVY LOAD

摘要

The present invention relates to a hydraulic emergency stop safety brake control device for a high load escalator, comprising: a reverse rotation sensor for sensing a rotational direction of an escalator rotation shaft; 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; It includes a control unit for determining whether or not according to the signal of the reverse rotation sensor and the speed detection sensor to send a signal to the relay panel for applying power to the emergency stop safety brake. The emergency stop safety brake includes a brake disc additionally provided at one end of the escalator rotation shaft, and a hydraulic caliper for applying rotational pressure at both sides of the brake disc to block rotation. The hydraulic caliper includes a main body and a brake disc between the brake disc. The hydraulic fluid is supplied to the hydraulic pressure part of the piston while being operated by a pair of brake pads installed in the main body, a piston installed in the main body to press any one of the brake pads toward the brake disc side, and an applied power supply from the relay board. A hydraulic pump for moving to the brake disc side is provided. And a rechargeable battery providing emergency power to the hydraulic pump, wherein the relay panel applies electricity of the rechargeable battery to the hydraulic pump when the main power is cut off.
