Embodiment Construction

[0018] exist Figure 1 to Figure 5 In the shown embodiment, two brake pawls (1) with opposite braking directions are installed on the vehicle frame (7), and are connected to the brake pawl release plate (3) through flexible ropes (2), so that the brake pawls The movable claw is suspended at the bottom of the mine car, and the wheel (6) is equipped with a slider mounting seat (5), and the slider (4) is installed in the slider mounting seat, and can move back and forth in the mounting seat. When the mine car is in normal operation, , the centripetal force required for the slider to rotate with the wheel is in balance with the elastic force generated by the spring (10). When the mine car overspeeds, the centripetal force required for the slider increases, and the spring (10) is compressed. When the centripetal force increases to a certain value, the slider The block protrudes from the mounting seat and collides with the pawl release plate (3), causing the pawl release plate (3) t...

Abstract

The invention relates to an automatic mechanical running-preventing mine car comprising a mine car bucket (8), a braking device installed on a mine car frame (7) and a speed sensing device mounted on a wheel (6). The automatic mechanical running-preventing mine car is characterized in that: firstly, the braking device comprises a pair of braking claws (1) mounted on the mine car frame (7), the braking claws (1) are connected with a braking claw releasing plate (3) arranged on the mine car frame through a flexible rope (2), and an elastic element (9) is also arranged between the braking claws and the mine car frame; and secondly, the speed sensing device comprises a slide block installing seat (5) arranged on the wheel (6) as well as a slide block and a spring (10) which are both arranged in the slide block installing seat (5). When the mine car runs with excessive speed, the braking claws can automatically fall under the action of gravity and elastic force so that the mine car is braked in time. The invention solves the problems of complex structure, high cost and short service life of a traditional running-preventing mine car, and is particularly suitable for underground transportation of a mine.

Description

technical field [0001] The invention relates to an automatic anti-running mine car, in particular to a mechanical automatic anti-running mine car for avoiding accidents of the mine car sports car. Background technique [0002] In existing mines, the mine car for the tunnel continues to use the basic form that two pairs of wheels that can rotate freely are arranged on the vehicle frame, and the mine car is lifted to the ground by a winch. When the rope breaks or comes off the hook, 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 the mine car; (2) detecting the operation of the mine car through infrared detection elements Speed, using net fen...
