The invention discloses a device for preventing travelling wheels of a cart of an incoming coal sampling machine from derailing. The device comprises a fixed plate arranged on the sampling machine, a chassis assembly arranged on the fixed plate, a limiting shaft assembly arranged on the chassis assembly and a limiting disc assembly rotationally arranged on the limiting shaft assembly. According to the device for preventing the traveling wheels of the cart of the coal sampling machine from derailing, the fixing plate, the chassis assembly, the limiting shaft assembly and the limiting disc assembly are arranged, the fixing plate is installed on the sampling machine, rolling friction is conducted between the limiting disc assembly and a rail, the height of the bottom face of the sampling machine is increased through the height of an anti-falling unit in the vertical direction, and therefore the sampling machine is prevented from falling off. Further, the sampling machine is effectively prevented from being easily separated from the track or inclining when bumping due to external force; and the derailing probability and the maintenance cost are reduced.
本发明公开了一种防止入厂煤采样机大车行走轮脱轨装置,包括设置于采样机上的固定板、设置于固定板上的底盘组件、设置于底盘组件上的限位轴组件,以及转动设置于限位轴组件上的限位盘组件。该防止入厂煤采样机大车行走轮脱轨装置,设置了固定板、底盘组件、限位轴组件,以及限位盘组件,通过将固定板安装在采样机上,且限位盘组件与轨道之间进行滚动摩擦,由防脱单元在竖直方向上的高度对采样机底面的高度进行加长,进而有效防止了采样机在受到外力发生颠簸时轻易与轨道分离或者发生倾斜;降低了脱轨的概率和维护成本。
