Anti-falling mine car track

Abstract

The invention discloses an anti-falling mine car track. The anti-falling mine car track comprises a track body, and a mine car slides on the track body; a mounting plate is fixed to the end of the track, a winch is fixed to the upper side wall of the mounting plate, and a steel wire rope is fixedly connected between the driving end of the winch and the mine car; a supporting rod is fixed to the upper side wall of one end, close to the track body, of the mounting plate, a first wire guide wheel is mounted at the upper end of the supporting rod, a lifting plate is inserted in the mounting plate,a second wire guide wheel is mounted at the upper end of the lifting plate, and the steel wire rope is wound around the first wire guide wheel and the second wire guide wheel; and the lifting plate is in an L shape, a vertical plate is fixed to the end of the lifting plate, and a compression spring is fixed between the end of the lifting plate and the lower side wall of the mounting plate. According to the anti-falling mine car track, when the steel wire rope breaks, by utilizing the disengagement of clamping columns from the positions between rotating plates and the track body in rotation ofa disc, the rotating plates rotate to the upper side of the track body and prevent the mine car from continuing to move, and thus the safety of the mine car in the use process is guaranteed.

Description

technical field [0001] The invention relates to the field of mine car technology, in particular to a fall-preventing mine car track. Background technique [0002] A mine car is a narrow-gauge railway transport vehicle for transporting bulk materials such as coal, ore and waste rock in a mine. Generally, it must be pulled by a locomotive or a hoist, pulled by a locomotive or a winch, and transports coal, gangue, equipment, equipment and personnel. . It is the largest and most widely used transportation equipment in coal mines. [0003] During the use of the mine car, when the wire rope of the hoist breaks, the mine car will slide from top to bottom under the action of the height drop. If the mine car cannot be stopped quickly, it will cause damage to the mine car, and Impact on machinery such as tracks, or even cause safety accidents. Contents of the invention [0004] The object of the present invention is to solve the problems in the background technology, and propose ...
