Power unit for tracklayer which bridges nonstandard gauge railway

Abstract

The invention provides a power unit for a tracklayer which bridges a nonstandard gauge railway, relates to a power unit for automatic walking of the tracklayer which bridges the nonstandard gauge railway, and is mainly used for solving the problem that a conventional standard gauge cannot meet the requirement of the tracklayer which bridges the nonstandard gauge railway. The power unit comprises a power unit and a power wheel pair, wherein a traction motor of the power unit is hung on a motor hanging beam, a cantilever beam and a crossbeam of a vehicle bogie, and is coupled with a high-speed end of a reducer casing through a transmission shaft, and a low-speed end of the reducer casing is in press fitting with an axle of the power wheel pair through a low-speed bull gear. The power unit disclosed by the invention is welded to a side frame of the vehicle bogie through the cantilever beam, through changing the distance between the inner sides of the wheel flanges of the integral wheels at the two ends of the axle of the power unit disclosed by the invention, a nonstandard gauge can be set as needed, and the requirements for the power of the automatic walking of the tracklayer which bridges the nonstandard gauge railway are met. The power unit disclosed by the invention is compact in structure, stable to operate, and convenient to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of railway bridge erecting and track laying machines, in particular to an autonomous power unit of a railway bridge erecting and track laying machine smaller than the standard gauge. Background technique [0002] In the prior art, the running part of the track laying machine is mainly composed of a standard gauge driving wheel set, a reduction box, a transmission shaft, a DC motor, etc. The standard gauge of the driving wheel set is that the inner distance between the two wheel rims is 1435mm, and the reduction box The reduction ratio is a fixed value. However, some railways currently use non-standard gauge gauges. For example, the inner distance between the two wheel rims is 1067mm. The existing standard gauge bridge and track laying machines cannot adapt to the construction of this non-standard gauge railway. The need for bridge and track laying machines.
