Horizontal pushing loading hydraulic control system and method of face shovel excavator and face shovel excavator
The invention provides a horizontal pushing loading hydraulic control system and method of a face excavator and the face excavator, and the horizontal pushing loading hydraulic control system of the face excavator comprises a detection module used for detecting target parameters and sending target signals; the control module is used for receiving the target signal and judging whether a bucket of the face excavator is located at a working node of horizontal pushing loading or not based on the target signal; the overflow valve group is communicated with a rodless cavity of a movable arm oil cylinder of the face excavator, the overflow valve group at least comprises high overflow working pressure A and low overflow working pressure B which are used for controlling the working pressure of the rodless cavity of the movable arm oil cylinder, the system pressure of the face excavator is C, and C is larger than or equal to A and larger than B; when the bucket is located at the working node of horizontal pushing loading, the control module controls the overflow valve set to operate under the low overflow working pressure B, so that when the pressure of the rodless cavity of the movable arm oil cylinder exceeds the low overflow working pressure B, hydraulic oil in the rodless cavity of the movable arm oil cylinder overflows, and automatic falling of the movable arm is achieved.
本申请提出了一种正铲挖掘机的平推装料液压控制系统、方法和正铲挖掘机，正铲挖掘机的平推装料液压控制系统包括检测模块，用于检测目标参数并发送目标信号；控制模块，接收目标信号，并基于目标信号判断正铲挖掘机的铲斗是否处于平推装料的工作节点；溢流阀组，与正铲挖掘机的动臂油缸的无杆腔连通，溢流阀组至少包括控制动臂油缸的无杆腔工作压力的高溢流工作压力A和低溢流工作压力B，正铲挖掘机的系统压力为C，其中，A≥C＞B；其中，当铲斗处于平推装料的工作节点时，控制模块控制溢流阀组在低溢流工作压力B下运行，使得动臂油缸的无杆腔压力超出低溢流工作压力B时，动臂油缸的无杆腔内的液压油溢流，以实现动臂的自动下落。
