The invention discloses a tire type highway-railway dual-purpose excavator walking system and an excavator. The tire type highway-railway dual-purpose excavator walking system comprises a mounting base, a walking support, a walking device and a mode switching device. The mounting seat is connected with the walking bracket; the mode switching device is connected with the mounting base and the walking support and used for switching the road mode and the railway mode of the excavator. The walking device is connected with the walking support and comprises a supporting structure, a driving shaft and a walking guide wheel, the driving shaft is connected with the supporting structure and perpendicularly connected with the center of the end face of the walking guide wheel, and in the road mode, the mode switching device controls the walking guide wheel to be suspended, tires on the excavator make contact friction with the ground, and the excavator is driven to walk; in the railway mode, the mode switching device controls the walking guide wheels to make contact with the rails and controls the driving shaft to make contact with tires on the excavator, and the tires on the excavator and the driving shaft generate contact friction to drive the excavator to walk. The product cost can be effectively reduced, and the heights of the walking guide wheels on the two sides of the vehicle can be automatically adjusted.
本发明公开了一种轮胎式公铁两用挖掘机行走系统及挖掘机,包括安装座、行走支架、行走装置和模式切换装置;安装座安装与行走支架连接;模式切换装置与安装座和行走支架连接,用以切换挖掘机的公路模式和铁路模式;行走装置与行走支架连接,包括支撑结构、驱动轴和行走导轮,驱动轴与支撑结构相连,且与行走导轮的端面中心垂直连接,在公路模式下,模式切换装置控制行走导轮悬空,由挖掘机上的轮胎与地面接触摩擦,带动挖掘机行走;在铁路模式下,模式切换装置控制行走导轮与铁轨接触,并控制驱动轴与挖掘机上的轮胎接触,由挖掘机上的轮胎与驱动轴产生接触摩擦,带动挖掘机行走。本发明能够有效降低产品成本,并能自动调节车辆两侧行走导轮高度。
