The jack comprises a jack body, a sensor assembly and a fixing assembly, the jack body comprises a cylinder seat, a cylinder barrel, an end cover and a piston assembly, the cylinder seat is provided with a first mounting through hole and a wire outlet hole, a piston rod is provided with a second mounting through hole, and the sensor assembly is arranged in the cylinder seat. The sensor assembly comprises a pull rope sensor and a sensor sleeve, the pull rope sensor is assembled in the first mounting through hole, the sensor sleeve is connected with the cylinder base and surrounds the pull rope sensor, the sensor sleeve is sleeved with a sleeve guide ring, and an annular gap is formed between the sleeve guide ring and the hole wall of the second mounting through hole; the fixing assembly is assembled in the second mounting through hole, and the steel wire rope is connected with the fixing assembly. The pull rope sensor is convenient to install and maintain, and the dismounting space is small. The sensor sleeve protects the steel wire rope, the sleeve guide ring and the inner wall of the piston rod form hydraulic damping, the influence of liquid flow and pressure fluctuation on the steel wire rope is reduced, and the measurement precision is improved.

    本发明公开了一种内置拉绳行程传感器的千斤顶,所述千斤顶包括:千斤顶本体、传感器组件和固定组件,千斤顶本体包括缸座、缸筒、端盖和活塞组件,缸座上设有第一安装通孔和出线孔,活塞杆上设有第二安装通孔,传感器组件包括拉绳传感器和传感器套筒,拉绳传感器装配在第一安装通孔内,传感器套筒与缸座相连,传感器套筒环绕拉绳传感器,传感器套筒上套设有套筒导向环,套筒导向环与第二安装通孔的孔壁之间具有环形间隙,固定组件装配在第二安装通孔内,钢丝绳与固定组件相连。拉绳传感器便于安装和维护,拆装需求空间小。传感器套筒保护钢丝绳,套筒导向环与活塞杆的内壁形成液压阻尼,降低液体流量和压力的波动对钢丝绳的影响,提高测量精度。
