Description

technical field [0001] The invention relates to a brake test bench for a mine hoisting disc brake, in particular to a scale-down test device for simulating the emergency braking of a hoist in a thousand-meter-deep shaft with high speed, large inertia, and high specific pressure, and belongs to the mine hoist testing technology field. Background technique [0002] At present, the mine hoist is an indispensable construction machinery in the process of deep resource exploration and mining. It is the hub connecting the underground production system of the mine and the ground industrial square, the throat of mine transportation, and occupies an extremely important position in the whole process of mine production. As the last and most critical safety guarantee equipment of the hoist, the brake device is an indispensable and important part of the hoist. Whether the brake device can work safely and effectively is directly related to the safe operation of the hoist, which has an im...

[0004] Chinese patent document CN206960122U discloses a test device for automobile disc brakes. The device can set the number of gripping heads according to the number of brake disc mounting holes, so that the brake disc fixture is suitable for various types of brake discs. However, this disc brake device is not suitable for research on the braking performance and quality of mine hoists.

[0005] Chinese patent document CN102749205A discloses a kind of automobile disc brake simulation brake test bench, which can truly simulate the work of the automobile brake system, and is also provided with an air convection device near the brake disc. However, this disc brake test The feature of the station is that it can simulate the actual braking environment of the car, which is very different from the braking condition of the disc brake of the deep well hoist, and cannot meet the simulation of the high-speed and heavy-load braking conditions of the deep well hoist over a kilometer.

The testing machine can test the tribological properties of friction materials, and can be used as a tribological performance testing device for mine hoist brake shoe materials. However, this device cannot test the simulated braking performance quality of mine hoist disc brakes.

[0008] However, there is no report on the scaling test device for simulating the emergency braking of the disc brake of the thousand-meter deep well hoist at high speed, large inertia, and large specific pressure.
