New type vehicle-running preventing device for slope mine

The utility model discloses a new type of anti-derail device applicable to single-track or double-track inclined shafts less than 30 degrees in inclination at coal mines etc, wherein two ends of the bayoneted wire cable 3 are respectively linked with the wire cable bayonet pin 2 and the lifting wire cable 10; the bolt battering ram device 5 is positioned at the front and rear wall, or two sides of the front end mine car 4 on the car group; the stopper 11 or 11A is hung on the front wall of the front end mine car 4; the stopper trigger 6 is positioned beside the steel rail 8; the car arrester 7 is positioned at the down slope end of the stopper trigger 6. when the mine car 4 (or the mine car group) moves downwards in the inclined shaft due to breaking of cable, breaking of chain or breaking of pin, the fracture or forward movement of the bayoneted wire cable 3 enables the bolt battering ram 5A or 5B of the bolt battering ram device 5 to fall, through the action of gravity or the motion of spring 13 or 13A, to a certain position and hit the stopper trigger 6 that proceeds to hit the car arrester 7 to move the car arrester 7 to grasp the front axle or rear axle of the mine car 4, and with help of the buffering, energy absorbing and braking part, downward movement of the mine car 4 is slowed down and is stably halted to guarantee safety of the mine car.
