The invention relates to a fixing structure for a stroke sensor of a hydraulic support jack, and belongs to the technical field of fully-mechanized coal mining support. The hydraulic support jack comprises a cylinder body, a piston rod, a cylinder bottom and a piston. An axial through hole and a radial through hole are formed in the cylinder bottom, the axial through hole is communicated with the radial through hole, one end of the inner side of the axial through hole is communicated with the interior of the cylinder body, one end of the inner side of the axial through hole is in threaded connection with a separation column, a cable socket is fixedly arranged on the outer side of the radial through hole, and a cable plug is fixedly arranged on the cable socket. A sensor rod body is fixedly arranged on the separation column, the sensor rod body is inserted into the piston rod in a sliding mode, the cable plug is connected with the sensor rod body through a cable, a magnetic ring is fixedly arranged at the bottom end of the piston rod, and the magnetic ring is connected to the outer side of the sensor rod body in a sliding and sleeving mode; the problems that a fixing structure of a stroke sensor of an existing hydraulic support jack is prone to being damaged and inconvenient to disassemble and assemble are solved.
本发明涉及用于液压支架千斤顶的行程传感器的固定结构,属于煤炭综采支护技术领域;所述液压支架千斤顶包括缸体、活塞杆、缸底、活塞;在缸底上设置有一个轴向通孔与一个径向通孔,轴向通孔与径向通孔相连通,轴向通孔的内侧一端与缸体内部相连通,在轴向通孔的内侧一端螺接有分隔柱,在径向通孔的外侧固定设置有电缆插座,电缆插座上固定设置有电缆插头,在分隔柱上固定设置有传感器杆体,传感器杆体滑动插接于活塞杆内部,电缆插头与传感器杆体通过电缆线相连接,在活塞杆的底端固定设置有磁环,磁环滑动套接于传感器杆体外侧;解决了现有的液压支架千斤顶的行程传感器的固定结构容易受到损坏、拆装不便的问题。
