Problems solved by technology
[0002] In mine production, the transport vehicle is an indispensable equipment. The existing mine transportation basically uses a hoist to complete the material up and down distance. When the material is lifted to the top and the transport vehicle drops to the bottom, braking and deceleration are required. The hydraulic brake decelerates, but the current technical considerations are not perfect, and has the following disadvantages: the hydraulic brake pushes the brake lever and the brake arm to clamp through the hydraulic pusher, and uses the brake shoe to brake the traction shaft at the same time, while the hydraulic pusher When working, a layer of oil film will be formed on the surface of the piston rod, and the oil will contact the air and oxidize to form sludge during use. At the same time, the dust content in the mine is large, and the dust particles adhere to the sludge surface of the piston rod, which will increase the energy consumption of the hydraulic pusher. Larger, and with the prolongation of the working time of the hydraulic pusher, more and more dust particles and sludge will accumulate, and in severe cases, the hydraulic rod will be stuck, which will lead to brake failure and threaten the life safety of underground workers

The invention discloses a hydraulic brake for a mine hoist. The hydraulic brake structurally comprises a brake arm, brake blocks, a fixed base, a brake spring, a hydraulic pusher and a brake lever, the fixed base and the surface of a workbench are fixed together through bolts, the brake arm and the fixed base are buckled mutually, and the brake blocks and the brake arm are fixed through screws. According to the hydraulic brake of the mine hoist, by mounting a push rod cleaning device, after braking of the hydraulic brake is completed, in the downward moving process of a lever push rod, the push rod cleaning device can effectively remove residual sludge on the surface of the lever push rod thoroughly, the situation that energy consumption of the hydraulic pusher is increased or the lever push rod is stuck when pushed out is avoided, and normal work of the brake and the life safety of downhole workers are ensured.
