The invention provides a side protection jack with a built-in stroke sensor, and belongs to the technical field of jacks, the side protection jack comprises a cylinder body, the cylinder body is provided with a cavity with an opening in one side, and one end, far away from the opening, of the cylinder body is provided with a connecting structure used for being connected with external equipment; a piston is arranged on the piston rod, the piston rod is assembled in the cylinder body in a sliding mode, a piston cavity is formed after the piston rod and the cylinder body are assembled, and the piston rod is controlled to stretch out and draw back by injecting and discharging high-pressure liquid into the piston cavity; an existing side protection jack is improved, the displacement sensor is installed in the cylinder body, deep hole machining is conducted on the piston rod, and a containing space is provided for the displacement sensor, so that the displacement sensor is arranged inside, the dilemma that observation needs to be conducted with naked eyes in the past is eliminated, the probability that a coal mining machine cuts a side protection plate is reduced, and the working efficiency is improved. The labor intensity is reduced, the working efficiency is improved, and technical support can be provided for intelligent mining.

    本发明提供一种行程传感器内置的护帮千斤顶,属于千斤顶技术领域,包括缸体,所述缸体开设有单侧开口的空腔,所述缸体远离该开口的一端设置有用于连接外部设备的连接结构;活塞杆,活塞杆上设置有活塞,活塞杆滑动装配在缸体内,活塞杆与缸体装配后形成活塞腔,通过向活塞腔注入、排放高压液体,以控制活塞杆伸缩;本发明对现有的护帮千斤顶进行了改进,在缸体内部安装了位移传感器,并通过对活塞杆进行深孔加工,为位移传感器提供容纳空间,从而实现了位移传感器内置,摆脱了以往需要肉眼去观察的困境,减少了采煤机割护帮板的几率,降低了劳动强度,提高了工作效率,可以为智能化开采提供技术支持。
