The rescue hydraulic pump comprises a base and a shell, the top of the shell is provided with the reciprocating structure, an inner cavity of the shell is slidably sleeved with a telescopic oil cylinder shell, an inner cavity of an oil cylinder mandrel is slidably sleeved with an oil guide pipe through a stop piston assembly, and the bottom of an oil cylinder is provided with a valve assembly. An oil bag is arranged outside the valve assembly, an oil pumping piston is slidably connected to an inner cavity of the oil pumping cylinder in a sleeved mode, and a stop valve is arranged at the top of the stop piston assembly. The rescue hydraulic pump with the reciprocating structure solves the problems that manual pressing wastes time and labor, when a large-weight object needs to be jacked, due to the fact that the weight of the object is large, the pressing resistance is increased in the jacking process, jacking is difficult, the risk of falling off is likely to occur in the jacking process, adjustment cannot be conducted on different grounds, and the working efficiency is high. And the final jacking process is not limited by the stroke, so that collision is easy to occur.

    本发明公开了一种带往复结构的救援液压泵,包括底座和外壳,外壳的顶部设置有往复结构,外壳内腔滑动套接有伸缩油缸壳,且油缸芯轴的内腔通过止停活塞组件滑动套接有导油管,打油缸的底部设置有阀门总成,阀门总成的外部设置有油囊,且打油缸的内腔滑动套接有打油活塞,且止停活塞组件的顶部设置有止停阀,本发明涉及汽车救援技术领域。该带往复结构的救援液压泵,解决了手动按压比较费时费力,以及当需要顶升大重量物品时,由于物品重量大,因此在顶升过程中按压阻力会增大,导致难以在顶升,顶升的过程中还会容易出现脱落的风险,以及在对不同的地面无法进行调整,最后顶升的过程没有行程的限制,容易出现碰撞的问题。
