The invention discloses a portable ultrahigh-pressure large-load jack, and relates to the technical field of hydraulic jacks. The portable ultrahigh-pressure large-load jack specifically comprises a base and manual pump assemblies, an oil liquid tank is fixed to one side of the surface of the base, and a supporting rod is arranged in an oil liquid inner cavity. An object supporting plate is weldedto the top of the supporting rod, and a first oil pipe is arranged at the bottom of the oil liquid tank. A first one-way valve is arranged at the tail end of the first oil pipe, and liquid inlet pipes are arranged at the top of the first one-way valve and the top of a second one-way valve. The manual pump assemblies are arranged above the liquid inlet pipes. According to the portable ultrahigh-pressure large-load jack, when the object supporting plate and the supporting rod need to ascend and are not in contact with objects, liquid in the oil liquid tank is drawn into the oil liquid inner cavity through a micro pump; meanwhile, people press a lever outer pipe and a lever inner rod, the oil liquid inner cavity can be fast filled with liquid, and therefore the effect of enabling the objectsupporting plate and the supporting rod to ascend fast is achieved; and according to the arrangement, the time needed by the contact between the object supporting plate and an object support can be shortened, and therefore the work speed is increased.

    本发明公开了便携式超高压大载荷千斤顶,涉及液压千斤顶技术领域,具体为底座和手动泵组件,所述底座表面一侧固定有油液箱,所述油液内腔内部设置有支撑杆,所述支撑杆顶部焊接有撑物板,所述油液箱底部设置有第一油管,所述第一油管末端安置有第一单向阀,所述第一单向阀与第二单向阀顶部均设置有进液管,所述手动泵组件设置于进液管上方。该便携式超高压大载荷千斤顶,撑物板、支撑杆在需要上升且未接触到物体时,由微型泵将油液箱内部的液体抽送至油液内腔中,同时人们按压杠杆外管、杠杆内杆即可使油液内腔内部快速充满液体从而达到让撑物板、支撑杆快速上升的效果,该设置有利于缩短撑物板与物体支架接触所需时间,从而提高作业速度。
