Problems solved by technology

[0002] The brake shoes of the mine hoist are used to stop the movement of the hoist. The long-term friction between the brake shoes and the hoisting wheel will cause the wear and tear of the brake shoes to become thinner. The thinner wear of the brake shoes will lead to longer braking strokes and lower transmission efficiency. The deceleration effect is reduced, and there are safety hazards at the same time

Abstract

A mine hoist brake shoe clearance adjustment device, in the mine hoist field, including a hoisting wheel, is characterized in that it includes: a brake device, an adjustment device, an electromagnetic device, a rotating shaft, a motor, and a casing, and the casing has an inner top wall A brake device is symmetrically fixedly connected to the bottom wall, an electromagnetic device is fixedly connected to the lower end of the adjustment device, a motor base is arranged on an inner wall of the housing, the motor is fixed on the motor base, and one end of the rotating shaft is connected to the motor base. The inner side wall of the outer shell is rotationally connected, the other end of the rotating shaft is fixedly connected with the output shaft of the motor, and a lifting wheel is fixedly connected to the rotating shaft, and the lifting wheel is located between the two braking devices on the inner top surface and the bottom surface of the outer shell . The invention can adjust the gap between the worn brake shoe and the lifting wheel, ensures the deceleration effect, and avoids accidents caused by excessive wear of the brake shoe.

Description

technical field [0001] The invention belongs to the field of mine hoists, in particular to a brake shoe clearance adjustment device for mine hoists. Background technique [0002] The brake shoes of the mine hoist are used to stop the movement of the hoist. The long-term friction between the brake shoes and the hoisting wheel will cause the wear and tear of the brake shoes to become thinner. The thinner wear of the brake shoes will lead to longer braking strokes and lower transmission efficiency. The deceleration effect is reduced, and there are safety hazards at the same time. Contents of the invention [0003] The object of the present invention is to provide a mine hoist brake shoe clearance adjustment device to solve the above-mentioned problems in the prior art. [0004] To achieve the above object, the present invention takes the following technical solutions: [0005] A mine hoist brake shoe clearance adjustment device, including a hoisting wheel, is characterized ...
