Description

Technical Field

[0001] The present invention relates to the field of vehicle arresters, and more particularly to a vehicle arrester for mining. Background Art

[0002] The car stopper, also known as the parking device, is one of the important facilities in the coal mine transportation system. It is an anti-runaway device and is generally installed on the top of a slope. The existing car stopper generally sets a car stopper mechanism on the rotating part, and drives the rotating part to rotate the car stopper mechanism to the track through the driving part. The rigid contact between the wheel and the car stopper mechanism prevents the vehicle from continuing to slide backward. When it is not necessary to stop the vehicle, the driving part drives the rotating part to rotate and rotates the car stopper mechanism away from the track to allow the vehicle to pass smoothly. With the increase in the loading capacity of the vehicle, the above-mentioned car stopper is prone to excessive impact force when stopping the vehicle, causing the car stopper structure to fall off from the rotating part and lose its car stopper function, posing a certain safety hazard.
