A track-laying machine with automatic span change during the traveling process and its application method

Abstract

The invention relates to a track layer automatically changing the span in the advancing process and a use method. The track layer is characterized in that the track layer is composed of a guide column type upper crossbeam assembly, supporting leg assemblies, walking beam assemblies, a lifting system, a track panel carrying pole, a transversely-moving span changing system and an electrical control system. The whole guide column type upper crossbeam assembly is of an I-shaped structure. The lifting system is erected at the center of the guide column type upper crossbeam assembly. The left end and the right end of the guide column type upper crossbeam assembly are connected with the walking beam assemblies at the left end and the right end through the supporting leg assemblies vertically arranged at the left end and the right end. The guide column type upper crossbeam assembly and the supporting leg assemblies are each of a telescopic structure. Compared with the prior art, the upper crossbeam assembly and the supporting leg assemblies are connected through guide sleeves and guide columns, automatic span changing in the empty heavy load advancing process is achieved through the transversely-moving span changing system, no time is consumed during interval span changing, the track layer travels on a main track, labor is greatly saved, and the construction speed is greatly increased.

Description

[technical field] [0001] The invention belongs to engineering technology science, and relates to the design and use method of a rail laying machine for urban rail transit engineering. [Background technique] [0002] At present, in the track-laying construction of urban rail projects in my country, the traditional track-laying equipment mainly has two structural types: simple assembly and conversion type and manual and hydraulic power improved type. The simple track-laying machine for assembly and conversion needs to be shut down and disassembled before being assembled during the conversion and spanning process of the working surface. Due to the narrow space of the tunnel, it is difficult to hoist and change the span, and the work efficiency is low, labor-intensive and time-consuming; Although there is no need for disassembly during the process, it is necessary to stop the machine and manually raise and move the span at a low level. Although it saves the invalid time for chan...

Problems solved by technology

[0003] The purpose of the present invention is to design a new type of track laying machine, which has automatic span change when empty and heavy load, automatic contraction of the height and width of the whole machine, and a track laying machine that can travel on both the gauge of the working section and the gauge of the main line. To solve the problems of repeated disassembly and assembly and labor-intensive entry and exit before and after the construction of the existing track-laying machine during frequent span-changing operations, it adopts the principle of power-driven contraction of the upper part and progressive offset and indentation of the lower part along the longitudinal track. Carry out optimization and improvement to achieve zero time-consuming for the track laying machine on the working surface of the subway track construction, without dismantling the working surface transfer and long-distance transfer transportation of the whole machine, electric retractable cables, automatic clamping and semi-automatic unloading of the rail row, greatly Improve ergonomics
