Hydraulic control system of pile driver
The invention provides a hydraulic control system of a pile driver. The hydraulic control system comprises a pumping device comprising a first main pump and a second main pump; a plurality of execution elements configured to drive the pile driver to execute pile driver tool actions, wherein each execution element comprises a machine tool vibration motor; an oil supply valve group arranged between the pumping device and the execution elements, wherein the oil supply valve group has a first working state, a second working state and a third working state, in the first working state of the oil supply valve group, the first main pump supplies oil to the execution elements except the machine tool vibration motors independently, in the second working state of the oil supply valve group, the first main pump independently supplies oil to the machine tool vibration motors, and in the third working state of the oil supply valve group, the first main pump and the second main pump simultaneously supply oil to the machine tool vibration motors; and a first control valve group arranged between the pumping device and the oil supply valve group and configured to switch the working states of the oil supply valve group. The operation safety of the pile driver can be improved.
本公开提供一种打桩机液压控制系统，包括：泵送装置，包括第一主泵和第二主泵；多个执行元件，被配置为驱动打桩机执行打桩机具动作，多个执行元件包括机具振动马达；供油阀组，设置于泵送装置和多个执行元件之间，供油阀组具有第一工作状态、第二工作状态和第三工作状态，在供油阀组的第一工作状态，第一主泵单独向除机具振动马达外的执行元件供油，在供油阀组的第二工作状态，第一主泵单独向机具振动马达供油，在供油阀组的第三工作状态，第一主泵和第二主泵同时向机具振动马达供油；和第一控制阀组，设置于泵送装置和供油阀组之间，第一控制阀组被配置为切换供油阀组的工作状态。本公开有利于提高打桩机操作的安全性。
