[0002] Ore is an important resource, and ore mining refers to the process of mining useful minerals from the earth's interior or surface. In mining operations, mined ore is transported mainly by mine cars. When the mine car reaches the end of the track, it needs to be stopped by a car stop device. The existing track end is equipped with a car stop device.

[0003] A mine car stop device (with authorization announcement number CN217623586U) is provided with a baffle that can stop the mine car. When the baffle is subjected to force, it transmits the force to the third spring and the sliding cylinder. At this time, the third spring is compressed. When the force is large, the sliding cylinder slides in the positioning cylinder and collides with the stop ball. The force pushes the stop ball into the first sliding hole. Multiple stop balls achieve phased interception. The cooperation of the top plate and the second spring also limits the sliding cylinder.

[0004] However, this kind of mine car stop device has some shortcomings in actual use. When the mine car reaches the end of the track, it collides with the baffle. When the impact occurs, it will generate a reaction force on the mine car, causing it to move back and disengage from the unloading position at the end of the track. Therefore, the utility model is proposed to solve the above problems. UTILITY MODEL CONTENT
