Track laying device and laying method for rail transit engineering construction

Abstract

The invention discloses a track laying device and a laying method for rail traffic engineering construction, including a track laying machine, a tail end guide assembly, a positioning seat structure, a transportation limit assembly and a joint detection assembly, and the tail end guide assembly is movably arranged on the above the track laying machine, the positioning seat structure is fixedly arranged on one side of the track laying machine, the transport limit assembly is fixed inside the track laying machine, and the joint detection assembly is fixed on the The inner bottom of the above-mentioned track laying machine; the present invention can therefore realize the effect of quickly aligning and connecting the ends of the two sections of track, speed up the progress of laying, and does not need manual guidance by the operator; The separation of the row, followed by the completion of the splicing detection work, the connection detection results are provided in time, and finally, it is convenient for the single-section track to be quickly fixed to the best balanced position.

Description

technical field [0001] The invention relates to the technical field of track laying equipment, in particular to a track laying device and a laying method for rail transit engineering construction. Background technique [0002] Track laying machinery refers to special machinery for laying track and ballast. There are two types: one is to transport the rail row assembled at the base to the laying site by a special train, and then use a track laying machine to lay the rail row on the track. On the bed, the other is a track laying unit consisting of a traction power part, a main machine of a rail laying machine, a sleeper rotating gantry crane, a double sleeper, and a rail transport vehicle. , and then put the rail on the rail bearing platform of the sleeper to complete the rail laying operation; [0003] However, the existing track laying devices have the following drawbacks: [0004] (1) The existing track laying device does not have a device for automatically aligning the t...

AI Technical Summary

Problems solved by technology

[0004] (1) The existing track laying device does not have a device for automatic alignment of the two tracks during laying work, and usually requires manual or other mechanical assistance to align and connect the tracks. These two methods are difficult to manually assist, and The degree of industrial accidents is high. In addition, the use of additional mechanical devices to assist movement will consume additional power, and it is not conducive to use under conditions of limited space;

[0005] (2) The existing track laying device does not provide a device for direct detection of the track joints during laying work. It needs to be manually inspected section by section after the laying is completed. The manual inspection method has a large workload and cannot be timely Abnormalities are detected, and remedial measures cannot be taken in time;

[0006] (3) During the continuous replenishment process of the assembled rail row, its final placement position will be shifted to some extent. Therefore, in the subsequent moving process, the best balance point needs to be continuously adjusted according to its placement position. Therefore, the progress of laying is affected, and the subsequent connection process also requires constant adjustment, which not only consumes time but also affects the work of rail splicing
