The invention relates to a hydraulic jack with an auxiliary supporting function. The jack comprises a base, a hydraulic mechanism, a supporting mechanism and a cleaning mechanism, wherein the hydraulic mechanism comprises a hydraulic cylinder, a piston, a supporting rod and a pressing plate, and the supporting mechanism comprises a fixing plate, a sliding block, a first fixing rod, a first spring,an ejector block, a round rod, a second fixing rod, a second spring, a rubber ball and a connecting rod; the cleaning mechanism comprises a push rod, a rack, a gear, a rolling rod, a first bevel gear, a second bevel gear, a rotating shaft, a first rolling wheel, a belt, a second rolling wheel, a circular ring and a brush head. The hydraulic jack with the auxiliary supporting function supports a pressing plate through the supporting mechanism, and leakage of the hydraulic mechanism due to overload of the pressing plate is avoided; Meanwhile, the brush head rotates under the transmission actionof the rack, the gear, the belt and the rolling wheel to clean the round rod circumferentially, so that dust or rust adhering to the round rod is avoided, it is ensured that the pressing plate ascends smoothly, and therefore, the pressure of the hydraulic cylinder is reduced, and the hydraulic jack is protected from being damaged.

    本发明创造涉及一种带有辅助支撑功能的液压千斤顶,包括底座、液压机构、支撑机构和清洁机构,液压机构包括液压缸、活塞、支撑杆和压板,支撑机构包括固定板、滑块、第一固定杆、第一弹簧、顶块、圆杆、第二固定杆、第二弹簧、橡胶球和连接杆,清洁机构包括推杆、齿条、齿轮、滚动杆、第一伞齿轮、第二伞齿轮、转轴、第一滚轮、皮带、第二滚轮、圆环和刷头,该带有辅助支撑功能的液压千斤顶,通过支撑机构对压板提供支撑,避免因压板超载导致液压机构发生泄漏,同时通过齿条和齿轮以及皮带和滚轮的传动的作用下使得刷头转动,对圆杆实现周向清洗,避免圆杆上粘附灰尘或者生锈,保障压板的顺畅上升,从而减少液压缸的压力,保护液压千斤顶不受损坏。
