AI Technical Summary

Problems solved by technology

However, equipment investment is huge, crew training is difficult, electrical and hydraulic systems have a high failure rate, 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
Due to the rapid update of the new technology policy of the Ministry of Railways, the factory and section repairs required by the track-laying unit have not yet been designated for repairs, and the transportation of the track is difficult, and the safety of the track cannot be guaranteed.

Embodiment 1

[0065] Regarding the track laying of ballasted ballast bed, as attached figure 1 shown.

[0066] The track laying unit is organized in sequence in the track laying direction: long rail tractor 1, main engine 2, auxiliary machine 3, sleeper transport wagon group 6 carrying sleeper truck 4, and locomotive 7.

[0067] Construction is carried out as follows:

[0068] 1. Preparation

[0069] (1) The long rail tractor 1 enters the track laying site ahead of time; the main engine 2 and auxiliary engine 3 are pushed by the locomotive 7 to the place where the line is to be laid, stop at a distance of about 0.5m from the end of the laid track, connect the pipeline of the unit, and start the engine. Build pressure in the hydraulic system and close the gears of the bogie drive mechanism;

[0070] (2) Put the crawler traction device 13 at the front end on the ballast with the truck-mounted crane 12 that comes with the main engine 2; make the main engine 2 ride on the crawler traction de...

Embodiment 2

[0091] Regarding the track laying of ballastless ballast bed, as attached figure 2 shown.

[0092] Construction is carried out as follows:

[0093] The track laying units are grouped sequentially in the track laying direction: ballastless track laying device 5, main engine 2, auxiliary machine 3, sleeper transport wagon set 6, locomotive 7.

[0094] (1) Hoist the crawler traction device 13 to the main engine 2 with the locomotive crane 12, so that the bogie 17 at the front end of the main engine 2 is supported on the laid rail. Stop at 0.5m away from the laid steel rail;

[0095] (2) Preset a ground roller 8 every 10m on the bearing groove of the ballastless ballast bed;

[0096](3) The long rail is pulled out from the sleeper rail transport wagon group 4 by the hoisting device 11 on the main engine 2, and separated to both sides of the car body through the rail splitting device, and enters the rail pushing mechanism 20;

[0097] (4) The rail pushing mechanism 20 drives t...

Abstract

The invention discloses a multi-sleeper type long rail laying machine set and a rail laying method, wherein the multi-sleeper type long rail laying machine set comprises a long rail tractor, a ground roller, a main machine, an auxiliary machine and sleeper carriers, and is characterized in that: when a ballast track bed rail is laid, the multi-sleeper type long rail laying machine set is sequentially provided with the long rail tractor, the main machine, the auxiliary machine, a sleeper carrier group loading with the sleeper carriers and a locomotive along the rail laying direction; and when a ballastless track bed rail is laid, the multi-sleeper type long rail laying machine set is sequentially provided with a ballastless track bed laying device, the main machine, the auxiliary machine, the sleeper carrier group and the locomotive along the rail laying direction. The machine set can satisfy the requirements on laying a long rail of 500m and the sleeper at once under the condition of ballast track bed and ballastless track bed laying, and meanwhile, the cost performance of a construction method is obvious, and the operation efficiency and laying quality are as good as those of a single sleeper continuous laying method.

Description

technical field [0001] The invention relates to a railway track construction locomotive unit and a track laying method, in particular to a long rail track laying unit and a track laying method, which are mainly used in the laying construction of long steel rails on ballasted roadbeds and ballast-free roadbeds. Background technique [0002] According to the plan of the Ministry of Railways, my country will build a total of 11 passenger dedicated lines with four vertical and four horizontal lines and three regional intercity express passenger transport channels. All new passenger dedicated lines will be constructed with 500m long steel rails. The traditional construction method is the replacement of rails. This construction method is easy to operate and easy to maintain when the equipment is mature, but the process is cumbersome, the work efficiency and automation are low, and the labor intensity is high. At present, the single-sleeper continuous laying method has basically be...
