Linear walking module and excavator
The embodiment of the invention provides a linear walking module and an excavator and relates to the technical field of hydraulic control. The linear walking module comprises a first pressure pump, asecond pressure pump, a pilot pump, a linear walking valve element, a left walking valve element, a right walking valve element and a one-way regulation assembly. The linear walking valve element comprises a first inlet, a second inlet, a first outlet and a second outlet. The first inlet is connected with the first pressure pump. The second inlet is connected with the second pressure pump. The first outlet is connected with the right walking valve element. The second outlet is used for being connected with a first working device. The one-way regulation assembly comprises a third inlet and a third outlet. The third inlet communicates with the second outlet. The third outlet communicates with the first inlet. The one-way regulation assembly can be used for regulating flow distribution of thesecond outlet. According to the linear walking module, the flow distribution of the second outlet can be regulated, the problem of linear walking deflection can be prevented, and the linear walking module can also adapt to operation needs under different working conditions.
本发明的实施例提供了一种直线行走模块和挖掘机，涉及液压控制技术领域。该直线行走模块包括第一压力泵、第二压力泵、先导泵、直线行走阀芯、左行走阀芯、右行走阀芯和单向调节组件。直线行走阀芯包括第一进口、第二进口、第一出口和第二出口；第一进口与第一压力泵连接，第二进口与第二压力泵连接，第一出口与右行走阀芯连接，第二出口用于与第一工作装置连接。单向调节组件包括第三进口和第三出口，第三进口与第二出口连通，第三出口与第一进口连通；单向调节组件能用于调节第二出口的流量分配。该直线行走模块能够调节第二出口的流量分配，不仅能防止直线行走跑偏的问题，还能适应不同工况下的作业需要。
