The invention relates to the technical field of bridge engineering equipment, and discloses a jack with a hydraulic oil leakage monitoring function. The jack with the hydraulic oil leakage monitoring function comprises a cylinder body, wherein a piston is assembled in the cylinder body, and fixedly connected with a top pillar, an oil pumping port is formed in the side wall of the cylinder body, and the cylinder body communicates with a compensation cylinder. According to the jack with the hydraulic oil leakage monitoring function, when leakage occurs, early warning is triggered while pressure in the cylinder body is compensated, due to a long and thin monitoring flow channel, small leakage can cause large-distance movement of a movable plug, and the leakage can be found in time; and meanwhile, due to the fact that pressure compensation is carried out before the early warning, adverse effects of lag of the early warning are eliminated, and secondly, the pressure in the cylinder body is compensated through the pressure of the compensation cylinder during trace leakage, original low-viscosity liquid is replaced by high-viscosity liquid during massive leakage, the pressure compensation is carried out while the leakage is inhibited, and therefore, after the leakage of the jack occurs, a normal supporting force can be maintained for a relatively sufficient period of time.

    本发明涉及桥梁工程设备技术领域,且公开了一种带有液压油泄漏监测的千斤顶,包括缸体,所述缸体的内部装配有活塞,所述活塞固定连接有顶柱,所述缸体的侧壁设有泵油口,所述缸体连通有补偿缸。该带有液压油泄漏监测的千斤顶,在发生泄漏时,先对缸体中压力进行补偿的同时触发预警,由于监测流道的细长,较小的泄漏既会引起移动塞的较大距离移动,可以及时发现泄漏,同时由于预警前进行了压力补偿,消除了预警滞后的不利影响,其次,在微量泄漏时通过补偿缸的压力对缸体中压力进行补偿,而在大量泄漏时通过高粘度液体替换原先低粘度液体,抑制泄漏的同时进行压力补偿,因此,该千斤顶在泄漏发生后,有较为充裕的时长维持正常的支撑力。
