The invention provides a road-rail dual-purpose excavator traveling drive system and a road-rail dual-purpose excavator, and relates to the field of mechanical equipment. The main control valve of the machine is communicated with the main pump; the traveling unit includes a motor, a plunger motor, a first reversing valve, a control valve group, a first pipeline and a second pipeline, one end of the first pipeline and all One end of the second pipeline is communicated with the interface of the excavator main control valve in a one-to-one correspondence, the other end of the first pipeline is communicated with the first interface of the control valve group, and the second pipeline The other end is communicated with the second port of the control valve group, the third port of the control valve group is communicated with the first port of the motor, and the fourth port of the control valve group is communicated with the second port of the motor The interface is communicated; the first reversing valve is communicated with the first pipeline, the second pipeline and the plunger motor respectively.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a traveling drive system of 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 automated equipment for replacing labor are constantly appearing, and a road-rail dual-purpose excavator based on the excavator as the main body is one of them. [0003] The current road and rail excavators have the following shortcomings: [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, the anti-slope ability is lacking; [0006] 3) The main control valve of the excavator lacks effective braking ability when combined with any motor without a control va...
