SAFE-BRAKING CONTROL SYSTEM, MINE HOIST AND SAFE-BRAKING CONTROL METHOD

WIPO Patent Application WO/2018/082022

A1

Disclosed are a safe-braking control system, a mine hoist and a safe-braking control method. The safe-braking control system is used for safe-braking control of an engineering hoisting equipment, and comprises: a disk braking subsystem (100), which is used for safely braking a brake disc (3) of the engineering hoisting equipment by means of a brake shoe of a brake driven by hydraulic fluid; an electrically-controlled braking subsystem (200), which is used to brake a motor (5) of the engineering hoisting equipment when the disk braking subsystem (100) fails to brake. Because two sets of brake subsystems, namely the disk braking subsystem and the electrically-controlled braking subsystem, are provided for the engineering hoisting equipment, the electrically-controlled brake may be started in a timely manner in an abnormal situation of a mechanical brake control failing so as to ensure safe-braking function of the engineering hoisting equipment, thereby avoiding occurrence of a serious accident and improving reliability and safety of safe-braking for the engineering hoisting equipment in abnormal operating conditions.
