The invention provides a road-railway dual-purpose excavator walking driving system and a road-railway dual-purpose excavator, and relates to the field of mechanical equipment. The road-railway dual-purpose excavator walking driving system comprises a main pump, an excavator main control valve and a walking unit, and the excavator main control valve communicates with the main pump. The walking unit comprises a motor, a plunger motor, a first reversing valve, a control valve set, a first pipeline and a second pipeline, one end of the first pipeline and one end of the second pipeline communicate with connectors of the excavator main control valve in a one-to-one correspondence mode, the other end of the first pipeline communicates with a first connector of the control valve set, the other end of the second pipeline communicates with a second connector of the control valve set, a third connector of the control valve set communicates with a first connector of the motor, and a fourth connector of the control valve set communicates with a second connector of the motor. The first reversing valve communicates with the first pipeline, the second pipeline and the plunger motor.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a driving system for a road-rail dual-purpose excavator and a road-rail dual-purpose excavator. Background technique [0002] With the rapid development of the railway system today, the related railway maintenance and construction equipment is also developing rapidly. Various automation equipment used to replace labor are constantly appearing, and a road-rail dual-purpose excavator based on the excavator as the main body is one of them. [0003] There are following disadvantages in current road-rail dual-purpose excavator: [0004] 1), the existing road-rail dual-purpose excavator lacks the towing function; [0005] 2) When the main control valve of the excavator is combined with any motor without a control valve, it lacks the anti-slope capability; [0006] 3) When the main control valve of the excavator is combined with any motor without a control valve, it lacks effectiv...
