1. Product description of disc brake of hoist in mining machine spare parts

The lifting system is the throat of mine production, and the brake device is the last and the most critical safety guarantee system of the hoist, and its main realization form is disc brake. In the process of mine production, disc brake shoe and brake disc frequently friction to control the normal operation of hoist, once the brake shoe failure, will lead to a serious accident hoist. Disc brake is used for working brake and emergency brake in mine hoist, and its drive and control are completed by a separate hydraulic station. The brake can replace the function of locking device, each brake is equipped with a stop valve, when repairing the brake, can be carried out one by one. Disc brake is composed of brake shoe, disc spring, hydraulic components, lining plate with cylinder, sealing ring and brake body. It is powered by a butterfly spring and released by pressure oil from a hydraulic station.

2. Notes for use and maintenance of disc brake of hoist in mining machine spare parts, common faults and handling methods

(1) The brake shoe shall not stick to oil, and the brake disc shall not have oil in use, so as not to reduce the friction coefficient of the brake shoe and affect the braking force;

(2) Check the brake shoe clearance frequently in normal use. If the brake shoe clearance exceeds 2mm, adjust it in time to avoid affecting the braking force;

(3) in the use of heavy weight in the mine, can not rely on mechanical braking, which will make the brake disc heating, once there is an emergency will affect the braking torque, resulting in a major accident, so should use dynamic braking.

(4) When replacing the brake shoe, pay attention to pressing the brake shoe tightly. If the size does not meet the requirements, it should be repaired.

(5) In the normal operation of the hoist, if the brake hydraulic cylinder is found to leak oil, the sealing ring should be replaced in time;

(6) When repairing the brake disc, the container should be separated on the bottom of the well or the tank at the wellhead (empty container), or the two containers should be lifted to the middle balance state for maintenance, and one or two brakes should be in the braking state during maintenance.

(7) The roughness of the brake disc is not enough and the deflection of the end face of the brake disc will accelerate the wear of the brake shoe, so it is recommended to load the brake disc;

(8) Single rope hoist due to the wear of the main bearing bearing bush caused by the large axial channelism of the brake disc, will accelerate the wear of the brake shoe, it is recommended to repair the main bearing bearing bush;

(9) When the lifting machine is found to loosen the brake slowly in normal operation, the relief valve should be used to deflate;
