Heavy car arrester used at mine wellhead

The invention provides a heavy car arrester used at a mine wellhead, which comprises two groups of limiters, the two groups of limiters are arranged at the position of the mine wellhead in a side-by-side opening manner, the two groups of limiters are arranged to be opened in one direction, and the opening direction of the two groups of limiters is opposite to the driving-in direction of a car. According to the car arrester which is designed in a side-by-side door mode and can only be opened in one direction, all main structures are heavy parts and are subjected to reinforcement treatment, the assembly structure is simple, the strength is high, the anti-collision capacity is high, a vehicle can be forcibly stopped even if the vehicle is subjected to rapid impact, and the accident that a mine truck collides into a well hole is avoided. 本发明提供了一种矿山井口使用的重型阻车器，包括两组限位器，两组限位器之间呈对开门方式安装于矿山井口位置，两组限位器均设置成单向开启，所述两组限位器的开启方向与车辆的驶入方向相反。本发明设计的呈对开门方式、只能单向开启的阻车器，各主要结构均为重型部件且加固处理，组装结构简单、强度高、抗撞击能力强，即便是面对车辆的快速冲击也能将车辆逼停，以避免发生矿卡撞入井
