A railway track laying machine capable of carrying load and moving across the line

Abstract

The invention discloses a railway track laying machine capable of moving transversely to step over a railway line under loads, and belongs to the field of railway construction equipment. Two groups of four walking mechanisms are arranged symmetrical about the center of a main rack to be fixedly connected with a horizontal longitudinal beam of the main rack through outer walking transverse beams of the walking mechanisms. Two groups of four transverse moving mechanisms are fixedly connected with the horizontal longitudinal beam of the main rack through outer transverse beams of the transverse moving mechanisms. Inner transverse beams of the transverse moving mechanisms are in sliding fit with the outer transverse beams and move transversely in a stretching and contracting mode relative to the outer transverse beams through stretching and contracting movement of transverse moving oil cylinders arranged in the inner transverse beams, so that the main rack and the outer transverse beams stretch and contact to move transversely to step over the railway line. Inner walking transverse beams of the walking mechanisms are in sliding fit with the outer walking transverse beams and move transversely in a stretching and contracting mode relative to the outer walking transverse beams through stretching and contracting movement of horizontal oil cylinders arranged in the inner walking transverse beams, and the walking mechanisms walk through walking crawler belts. In this way, the railway track laying machine can directly step over the railway line under loads through the walking mechanisms to perform track laying in a complex terrain, the walking mechanisms and the transverse moving mechanisms can be flexibly switched, and therefore the railway track laying machine completes track laying comprehensively with the function of moving transversely to step over the railway line under loads and improves the working efficiency of track laying.

Description

technical field [0001] The invention relates to a railway track-laying machine capable of laterally moving across a line with a load, belonging to the field of railway construction equipment, in particular to railway track-laying equipment. Background technique [0002] Railway is an important part of transportation and plays a huge role in promoting economic development. In order to meet the rapidly growing demand for railway transportation, according to the national railway development plan, my country's railways, especially high-speed railways, are currently in a stage of leapfrog development. [0003] Track laying is an important part of railway construction, and its laying efficiency and accuracy are directly related to the speed and quality of railway construction. At present, track laying machines at home and abroad are used to lay or replace tracks on existing railway tracks. Most of them are composed of main engine flat car, gantry crane mechanism, machine arm, and...

AI Technical Summary

Problems solved by technology

At present, track laying machines at home and abroad are used to lay or replace tracks on existing railway tracks. Most of them are composed of main engine flat car, gantry crane mechanism, machine arm, and running mechanism. track operation, low work efficiency; my country has a vast territory and complex terrain structure, and it is difficult to lay railway tracks, and because the existing track laying machine is bulky, it affects the passage of adjacent track vehicles during operation, and cannot work across tracks. Therefore, it cannot meet the requirements of complex terrain. The track-laying requirements of landform railway construction urgently require the development of track-laying machines that can work across lines to meet the needs of fast-growing railway construction.
