Description

Mine winder brake shoe clearance protection detection device Technical Field The utility model relates to the technical field of mine hoists, in particular to a mine hoist brake shoe gap protection detection device. Background The mine hoist is a large lifting mechanical device, and is driven by a motor to drive a steel wire rope to drive a container to lift in a shaft, so that a conveying task is completed, and the mine hoist is developed from an original water lifting tool. Modern mine hoists have large lifting capacity, high speed and high safety, and have been developed into full-automatic heavy mining machinery controlled by an electronic computer; Therefore, the patent with the grant publication number of CN220564071U discloses a device for protecting and detecting the gap between brake shoes of a mine hoist, which comprises a mounting base and a brake disc, wherein an annular fixing seat is welded and mounted at the top of the mounting base, a hydraulic cylinder is mounted in the annular fixing seat, and a brake shoe mounting seat is fixedly mounted at the movable end of the annular fixing seat.
