The invention relates to a hydraulic power unit and a continuous type lorry supporting leg with the hydraulic power unit, and relates to the field of hydraulic equipment, and the hydraulic power unit comprises a forward control oil way system, a reverse control oil way system, a power unit, a reversing valve, a plurality of overflow valves, a plurality of one-way valves and an oil return way. Communication of the power unit and the multiple hydraulic cylinders is achieved through the forward control oil way system and the reverse control oil way system, the flow direction of hydraulic oil in the forward control oil way system and the reverse control oil way system is controlled through the reversing valve, and the multiple hydraulic cylinders are controlled to stretch out and retract in order through the overflow valves. The effect that one switch controls a plurality of hydraulic cylinders to move in order is achieved, the number of switches of the lorry supporting leg is reduced, operation of people is facilitated, the response time of a whole hydraulic system is shortened, and then the response speed of the lorry supporting leg is increased.

    本申请涉及一种液压动力单元以及带有液压动力单元的连续式载重汽车支腿,涉及液压设备的领域,液压动力单元包括正向控制油路系统、逆向控制油路系统、动力单元、换向阀、多个溢流阀、多个单向阀和回油油路构成。本申请通过正向控制油路系统和逆向控制油路系统实现动力单元与多个液压缸的连通,通过换向阀控制正向控制油路系统和逆向控制油路中液压油的流动方向,通过溢流阀和溢流阀从而以控制多个液压缸有序伸出与收缩,实现一个开关控制多个液压缸有序活动的效果,减少载重汽车支腿的开关数量,方便了人们操作,且缩短了整个液压系统的反应时长,进而提高了载重汽车支腿的反应速度。
