Rapid pile lifting potential energy regeneration system of static pile driver and control method of rapid pile lifting potential energy regeneration system
The invention discloses a rapid pile lifting potential energy regeneration system of a static pile driver and a control method of the rapid pile lifting potential energy regeneration system. A main pressing oil cylinder and an auxiliary pressing oil cylinder are fixed to a machine body cross beam, and a pile clamping box is fixed to a piston rod lug ring of the main pressing oil cylinder through a pin shaft and moves up and down in the stroke of the main pressing oil cylinder along a guide rail; the pile clamping oil cylinder is arranged around the precast pile in the pile clamping box and moves in an oil cylinder stroke; the inlet end of the main pressure oil cylinder hydraulic control oil drain valve is communicated with a rodless cavity of the main pressure oil cylinder, the inlet end of the auxiliary pressure oil cylinder hydraulic control oil drain valve is communicated with a rodless cavity of the auxiliary pressure oil cylinder, the inlet end of the reversing valve is communicated with a rodless cavity of the auxiliary pressure oil cylinder, and the inlet end of the regeneration one-way valve is communicated with the outlet end of the reversing valve. The outlet end of the regeneration one-way valve is communicated with a rod cavity of the auxiliary pressure oil cylinder, and the inlet end of the overflow valve is communicated with a rodless cavity of the auxiliary pressure oil cylinder. The rapid pile lifting potential energy regeneration system of the static pile driver and the control method of the rapid pile lifting potential energy regeneration system are high in response speed and operation speed and small in pressure loss.
本发明公开一种静力压桩机的快速提桩势能再生系统及其控制方法，主压油缸、副压油缸固定在机身横梁上，夹桩箱通过销轴与主压油缸的活塞杆耳环固定，夹桩箱沿导轨在主压油缸行程上下运动，夹桩油缸在夹桩箱内围着预制桩布置在油缸行程内运动；所述主压油缸液控放油阀的进口端与主压油缸的无杆腔相通，副压油缸液控放油阀的进口端与副压油缸的无杆腔相通，换向阀的进口端与副压油缸的无杆腔相通，再生单向阀的进口端与换向阀的出口端相通，再生单向阀的出口端与副压油缸的有杆腔相通，溢流阀的进口端与副压油缸的无杆腔相通。此种静力压桩机的快速提桩势能再生系统及其控制方法的响应速度及运行速度快且压损小。
