Road-railway excavator walking system and control method
The invention discloses a road-railway excavator walking system and a control method. The walking system comprises a pilot oil pump, a high-pressure oil pump, a hydraulic oil tank, a monitor, a controller, an electromagnetic valve assembly, a guide wheel supporting control proportional valve, a supporting control switching shuttle valve, a guide wheel lifting switching valve, a guide wheel lifting oil cylinder, a guide wheel supporting control overflow proportional valve, a left walking pedal, a right walking pedal, a gear shifting handle and a switch assembly. The pilot oil pump provides a low-pressure control oil source for the walking system; the high-pressure oil pump provides a high-pressure oil source for an execution component of the walking system. During control, a guide wheel driving running mode is switched to during transition through guide wheel driving, and the guide wheel supports the highway-railway excavator according to the current value of the guide wheel support control proportional valve; in the rapid transition and construction process, manual operation such as guide wheel supporting adjustment, guide wheel or crawler belt driving mode switching and straight line driving starting is omitted, and the working intensity of a driving operator is reduced.
本发明公开了一种公铁两用挖掘机行走系统及控制方法，行走系统包括先导油泵、高压油泵、液压油箱、监控器、控制器、电磁阀组件、导轮支撑控制比例阀、支撑控制切换梭阀、导轮升降切换阀、导轮升降油缸、导轮支撑控制溢流比例阀、左行走脚踏、右行走脚踏、换挡手柄和开关组件；先导油泵为行走系统提供低压控制油源；高压油泵为行走系统的执行部件提供高压油源。本发明在进行控制时，通过导轮驱动转场时，切换到导轮驱动行驶模式，导轮根据导轮支撑控制比例阀电流值，将公铁两用挖掘机支撑起来；在快速转场和施工过程中，取消了导轮支撑调节、导轮或履带行驶模式切换、开启直线行驶类的人为操作，降低了驾驶操控人员的工作强度。
