The lifting jack is applied to a self-moving system of the reversed loader and comprises an outer barrel, a piston rod and the stroke sensor, the piston rod and the stroke sensor are arranged in the outer barrel, the two ends of the piston rod extend up and down in the vertical direction, and the stroke sensor is arranged in the outer barrel. The piston rod stretches up and down in the outer barrel, and when the piston rod stretches, the top of the piston rod is used for abutting against the bottom of a reversed loader of the reversed loader self-moving system, and then the reversed loader is lifted upwards; an installation hole with the extending direction consistent with the axis direction of the piston rod is machined in a deep hole in the bottom of the piston rod, and then a stroke sensor is installed and used for measuring the stroke variation of the piston rod in the vertical direction. The lifting sensor can remotely monitor the stroke change of the lifting jack, so that whether the jack fails or not and the ground clearance of the reversed loader are judged, the working efficiency is improved, and technical support is provided for intelligent mining.

    本发明涉及一种转载机自移用带行程传感器的抬高千斤顶,其应用于转载机自移系统,抬高千斤顶包括:外筒体、活塞杆和行程传感器,活塞杆和行程传感器分别设置在外筒体的内部,活塞杆的两端沿竖直方向上下延伸,活塞杆于外筒体的内部上下伸缩,且该活塞杆伸长时其顶部用于抵压于转载机自移系统的转载机的底部,进而向上抬升转载机;活塞杆自其底部深孔加工有延伸方向与该活塞杆轴线方向一致的安装孔,进而安装行程传感器,以用于测量活塞杆沿竖直方向的行程变化量。本发明中的抬高传感器可以远程监测抬高千斤顶的行程变化,从而判定千斤顶是否失效、转载机离地距离等,提高了工作效率,为智能化开采提供技术支持。
