Sleeper laying method and device of railway line main tracklayer

Abstract

The invention discloses a sleeper laying method and a device of a railway line main tracklayer. A one-time laying method is adopted, the main tracklayer is provided with a sleeper layer, the sleeper layer is positioned above a walking beam on the top of the front end of the main tracklayer, and the procedure for sleeper laying is implemented by the sleeper layer. The sleeper layer comprises a sleeper laying trolly, a sleeper lifting mechanism, a sleeper clamping mechanism, a hydraulic system, a transverse movement mechanism, a limiting mechanism and a milometer. The track laying of the railway line is completed by means of the coordinated operation of the sleeper laying trolly, the sleeper lifting mechanism, the sleeper clamping mechanism, the hydraulic system, the transverse movement mechanism, the limiting mechanism and the milometer. The method and the device have the advantage of simplifying construction process compared with the domestic sleeper laying at present; the sleeper layer is simple in structure, high in automated degree and convenient in maintenance, and saves the unit cost of construction; the device can complete a series of procedures at a time, including clipping and dropping of a plurality of sleepers and the like, is simple and convenient in operation, high in construction efficiency and safe and reliable, and can reach the positioning precision and the sleeper laying precision.

Description

technical field [0001] The present invention relates to a construction operation method and a system device of a railway line, in particular to a sleeper laying method and device for a track-laying main engine of a seamless railway line, which is mainly used for track-laying of new lines and existing lines of seamless lines Used in renovation work construction. Background technique [0002] In recent years, with the rapid development of high-speed and heavy-duty railways, the track structure has gradually been replaced by seamless lines from ordinary lines. Compared with ordinary lines, seamless lines have eliminated a large number of rail joints, so they have the advantages of smooth driving, low track maintenance costs, and long service life. They have become the main method of high-speed railway line construction at present. The seamless line is an important new technology of railway track. The line formed by welding ordinary steel rails into long rails of a certain leng...

AI Technical Summary

Problems solved by technology

[0006] These traditional seamless line laying methods do not require the use of special track laying machines to lay rails, and the process is cumbersome and requires a rail assembly base, low work efficiency and automation, and high labor intensity

Otherwise, the equipment investment is huge, the crew training is difficult, the failure rate of electrical and hydraulic systems is high, the troubleshooting and maintenance are difficult, and some accessories are easily damaged, resulting in the actual comprehensive operating efficiency of only 60-70% of the theoretical operating efficiency.

The pillow cloth device of the pillow continuous laying method is coordinated by many institutions, and the structure and control system are complex. As long as one of the links fails, the actions are difficult to coordinate, and the phenomenon of pillow jamming and pillow turning is prone to occur
