Highway-railway dual-purpose excavator power walking system and highway-railway dual-purpose excavator

Abstract

The invention provides a highway-railway dual-purpose excavator power walking system and a highway-railway dual-purpose excavator, the highway-railway dual-purpose excavator power walking system comprises a frame (10), a walking device, a connecting frame (20), a drive axle (30) and a walking guide wheel (40), the walking device is installed on the frame (10), the connecting frame (20) is connected with the frame (10), the drive axle (30) is connected with the connecting frame (20), and the walking guide wheel (40) is connected with the connecting frame (20). The drive axle (30) comprises a differential mechanism (31), and the walking guide wheel (40) is connected with the drive axle (30); the highway-railway dual-purpose excavator comprises the highway-railway dual-purpose excavator power walking system. The driving axle and the walking guide wheels are arranged, so that only one hydraulic motor is adopted to drive the excavator to run on a rail, and the production cost of the highway-railway dual-purpose excavator is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a power traveling system of a road-rail dual-purpose excavator and a road-rail dual-purpose excavator. Background technique [0002] With the continuous improvement of railway operation volume and operation speed, the requirements for railway repair and maintenance time and work efficiency continue to increase. The road-rail dual-purpose excavator that can be applied to the road and railway system can not only complete the work of ordinary excavators, but also can walk on the rails due to the installation of specific walking systems and working devices, and complete the required excavation on the railway along the road. Changing pillows, changing rails, pushing ballast, etc. [0003] In the related technology, there are two walking guide wheels on the driving side of the driving type road-rail dual-purpose excavator, and a hydraulic motor is installed at each walki...

AI Technical Summary

Problems solved by technology

[0003] In the related technology, there are two walking guide wheels on the driving side of the driving type road-rail dual-purpose excavator, and a hydraulic motor is installed at each walking guide wheel, and the walking guide wheels on both sides are simultaneously driven by two sets of hydraulic motors and drive The excavator is driving, and the production cost and maintenance cost of this kind of excavator are relatively high

Moreover, the height of the walking guide wheels on both sides of the road-rail excavator is the initial installation height. When the excavator travels through a road section where the heights of the two rails are inconsistent, the excavator will tilt the entire vehicle.

In addition, the speed of the walking guide wheels on both sides is the same. When the vehicle passes through a curve, due to the different travel distances of the walking guide wheels on both sides, it will cause the inner walking guide wheel to slip and the outer walking guide wheel to slip, which will increase the wear and tear of the vehicle. bad
