Hydraulic power station of travelling type high-pressure static-pressure pile planting machine
The invention belongs to the field of machinery, and particularly relates to a hydraulic power station of a travelling type high-pressure static-pressure pile planting machine. According to the technical scheme, the hydraulic power station of the travelling type high-pressure static-pressure pile planting machine comprises a shell, a diesel engine, a main pump, a gear pump, a main valve set, a main pump multistage flow control valve set and a multistage pressure output control mechanism; the diesel engine, the main pump and the gear pump are arranged in the shell; the main pump is a duplex plunger pump, and the two ends of the main pump are connected with the diesel engine and the gear pump through couplers correspondingly; the main pump multistage flow control valve set is arranged between the gear pump and the main pump; and the main valve set is connected with the main pump, and the multistage pressure output control mechanism is connected with the main valve set. According to the hydraulic power station of the travelling type high-pressure static-pressure pile planting machine, stepless adjustment of pressure and flow can be achieved, no redundant pressure or flow is generated,and the problem of power waste existing in a hydraulic power system of the existing static pressure pile planting machine is solved.
本发明属于机械领域，具体涉及一种行走式高压静压植桩机液压动力站。本发明的技术方案如下：一种行走式高压静压植桩机液压动力站，包括壳体、柴油发动机、主泵、齿轮泵、主阀组、主泵多级流量控制阀组和多级压力输出控制机构，所述柴油发动机、主泵和齿轮泵设置在所述壳体中；所述主泵为双联柱塞泵，其两端分别通过联轴器与所述柴油发动机及齿轮泵连接；所述齿轮泵与所述主泵之间设有主泵多级流量控制阀组；所述主阀组连接所述主泵，所述多级压力输出控制机构与所述主阀组连接。本发明能够实现压力和流量的无极调节，不会有多余的压力和流量产生，解决现有静压植桩机液压动力系统存在的功率浪费的问题。
