The invention discloses a double-cylinder transmission heavy vehicle stopping device for mine underground rail transportation, and relates to the field of mine underground auxiliary tools. Comprising a box body, two parallel air cylinders are arranged in the middle of the inner bottom face of the box body, the left portion and the right portion of the box body are each provided with a Z-shaped heavy collision block, the two heavy collision blocks are structurally symmetrical, and the upper portions of the two heavy collision blocks are main collision points. A collision block shaft penetrates through the lower inflection point of each heavy collision block, each collision block shaft is mounted on the box body through a respective collision block bearing seat, and the two collision block bearing seats are fastened on the left part and the right part of the box body through four mounting bolts respectively; and the rear shaft body parts of the two collision block shafts are sleeved with compression springs for buffering. The tail end of each heavy collision block is connected with a collision block pin shaft used for transmission, and the collision block pin shafts are correspondingly connected to piston rods of the air cylinders respectively. The device is easy to operate, high in automation degree, high in strength and convenient to install; the adaptability is high; the requirement of coal mine safety production is met, various vehicles can be smoothly passed, and the device can be used in various transportation systems of mines.
本发明公开了一种矿山井下轨道运输双气缸传动重型阻车装置,涉及矿山井下的辅助工具领域。包括箱体,箱体内底面中部设置有两个平行的气缸,箱体的左右部各设有一个呈Z形的重型撞块,两个重型撞块结构对称、且上部为主撞击点。每个重型撞块的下拐点处均穿有一根撞块轴,每根撞块轴通过各自的撞块轴承座安装于箱体上,两个撞块轴承座各自通过四个安装螺栓紧固于箱体的左右部;两根撞块轴的后轴体部分套有缓冲用的压缩弹簧。每个重型撞块的末端连接有一根用于传动的撞块销轴,分别对应连接于气缸的活塞杆。本发明操作简单,自动化程度高,强度大,安装方便;适应性强;满足煤矿安全生产的要求并能顺利通过各种车辆,可用在矿山各种运输系统。
