Intelligent travelling-preventing mine car

Abstract

The invention relates to an intelligent run-preventing mine car used in mining, comprising a mine car, a full-automatic intelligent detection and control system arranged on the mine car and a mine car braking device of rail-clamping type. The invention is characterized in that: a. the full-automatic intelligent detection and control system comprises a car speed sensor arranged on the mine car and a braking pressure sensor, and the two sensors are connected with an electronic controller, which is also connected with an alarm, a memory extended circuit, a power circuit, a motor driving circuit for a compressing and decompressing oil pump and a driving circuit for an electromagnetic valve; b. the braking device of rail-clamping type comprises a braking box, one end of which is provided with a trailing arm which is connected with the mine car, and the other end is provided with a guide wheel of rail-clamping type. The braking box is provided with a strong rail clamping mechanism. The invention solves the problems of complicated structure, high cost, unsatisfactory effect, unreliable work and large destructiveness, etc., of the existing run-preventing mine car device and the invention is especially suitable for underground transportation in a mine.

Description

(1) Technical field: [0001] The invention relates to mine safety equipment, which is an intelligent anti-running mine car used for carrying people and ore. (two) background technology: [0002] Inclined shaft rail manned / mine car is often a main car tow three (or four) ore barrels, and the mine car is lifted to the ground by a winch and a wire rope hanging on the coupler of the main mine car; but If this mining car suddenly breaks the rope or decouples during the inclined lifting process, it will lose control immediately, causing a major sports car accident. The problem of anti-car running in inclined shafts has always been a thorny problem that needs to be solved urgently in mine production. [0003] At present, the solutions to this problem include: (1) installing car barriers, car stops, automatic car arresters, fork car stoppers, etc. in the mine to directly block mine cars; (2) detecting the running speed of mine cars through infrared detection elements, Use net fence...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the first and second schemes above are: the interception device can only be used once, which not only wastes materials, but also destroys the continuity of mine production, and it takes time and effort to deal with accidents

Especially the manned mine car, the safety of the lives of the passengers on the car has not improved at all

The disadvantage of the third scheme is: the out-of-control heavy-duty mine truck will produce an impact force of about 10 tons, and the brake knife under the car is like cutting tofu with a sharp knife, cutting off the sleepers fixed on the ground one by one, or cutting them off one by one. Pull out the spikes on the sleepers that are not firmly fixed on the ground, so that the rail sleepers are separated, and the mine car cannot be stopped at all.

It is very difficult to implement the fourth plan. It costs more than 100,000 yuan to configure a brake wire rope with a length of several hundred meters in the mine together with the brake car. Not only the cost is too high, but also how to support the brake wire rope in the shaft is also a problem. The impediment effect of the moving steel wire rope on the normal running mine car should not be underestimated

The disadvantage of the fifth solution is: the suspended wedge brake not only has sparks in the brake, but has no buffer function, and the accuracy of falling rail positioning is low, and after troubleshooting, it is extremely difficult to manually take out the wedge-shaped steel block

Moreover, relying on mechanical components to detect and transmit the broken rope signal, the error is large, the reliability is low, and the delay time is long
