A mine wide-body dumper container tail plate automatic opening and closing device based on the gravity action is characterized in that the rear end of a container is hinged to a frame through a main rotating pin, the lower end of a tail plate is hinged to the container through a rotating hinge, and the device comprises traction units arranged on the two sides of the tail plate; the traction unit comprises a fixed pulley block mounted on the container, a movable pulley block mounted on the frame, a steel wire rope and a plurality of fixed pulleys mounted on the container; one end of the steel wire rope is fixed on the tail plate, and the other end of the steel wire rope sequentially bypasses the fixed pulley, the fixed pulley block and the movable pulley block and then is fixed on the container. The tail plate of the container is opened and closed under the action of thrust during lifting of the container and gravity during descending of the container, so that the container is simple and energy-saving; the problem that muck is accumulated near a retaining wall when the muck is dumped by a wide-body vehicle at present is solved, the safety risk during operation of a driver is reduced, and the cost of shoveling the accumulated muck by a mine side is also reduced.
一种基于重力作用的矿山宽体自卸车货箱尾板自动开合装置,货箱后端通过主转销与车架铰接,尾板的下端通过旋转铰链与货箱铰接,包括设在尾板两侧的牵引单元,所述牵引单元包括安装在货箱上的定滑轮组、安装在车架上的动滑轮组、钢丝绳和若干安装在货箱上的定滑轮;所述钢丝绳的一端固定在尾板上,钢丝绳的另一端依次绕过定滑轮、定滑轮组和动滑轮组后固定在货箱上。利用货箱举升时的推力及货箱下降时的重力作用实现货箱尾板的开合,简单节能;解决了目前宽体车倾倒渣土时在挡土墙附近堆积的问题,既降低了司机操作时的安全风险,也减少了矿方铲除堆积渣土的成本。
