Technical Field

The invention belongs to a vehicle-mounted dragging steel wire rope device of a mining vehicle in a stalling state, and particularly relates to the device which can be released immediately after a vehicle-mounted controller detects that the vehicle stalls, so that the stalled vehicle is dragged and decelerated.

Background

Because the environment under the coal mine is complex and the slope is more, the mine vehicle is often overloaded during underground operation, and the sliding phenomenon occurs when the brake fails or the vehicle is not engaged in the gear during the downhill. Because the vehicle is heavy in load and long in slope, the motion inertia of the vehicle is increased under the action of gravity acceleration, and the brake failure can be caused. In addition, the mining vehicle is operated for a long time, and maintenance work is rarely carried out, so that accidents caused by the fact that a brake system is out of order due to lack of regular maintenance are often caused. Because the brake pump has too many impurities, the sealing is not tight, the brake oil is seriously polluted and the like, the brake pump leaks oil after the brake system is heated, and the air storage tank or the pipeline interface leaks air, thereby causing the brake failure. The failure of the parts caused by improper operation of a driver during braking and the failure of the vehicle braking are also one of the main reasons, for example, the long-time downhill can cause the friction heat of the brake pad, the charring of the brake hub and the complete failure of the braking function. The stalling of a coal mine underground working vehicle due to brake failure is one of the main reasons for traffic accidents; when the mining vehicle runs fully and downhill, the vehicle cannot be shifted up when going downhill due to misoperation of a driver, and the main reason of accidents of the mining vehicle is also that the mining vehicle cannot be shifted up when going downhill.

With the large-scale mechanized production of coal enterprises, the transportation mode of rubber-tyred vehicles has: the auxiliary transportation system is simplified, and underground workers engaged in auxiliary transportation are obviously reduced; the multifunctional combined mining machine can realize multiple purposes, is convenient for the maintenance of fully mechanized mining working face equipment such as a hydraulic support, a coal mining machine, a conveyor and the like, and reduces the labor intensity of maintainers; the machine has the advantages of flexibility, simplicity in operation and good safety, is particularly suitable for auxiliary transportation of multi-branch roadways mined along coal seams and the like, but the safety protection problem of rubber-tyred vehicle transportation is not solved all the time.
