In the field of railway engineering, railway rails need to be replaced in time when reaching a certain service life, and the conventional railway rail replacement operation mainly adopts a manual rail replacement mode or a mechanical rail replacement mode in a skylight point. The manual rail replacement method needs more construction people, has low operation efficiency and high labor intensity, is easy to cause safety accidents, and has been applied less and less in overhaul construction. The mechanical rail replacement is to replace the steel rail by rail replacement equipment or a rail replacement vehicle, the rail replacement methods are basically the same, but all the work of rail unloading, rail welding, rail replacement and rail collection cannot be completed in the same skylight point.
In the prior art, the operation mode of adopting an off-line welding vehicle, a rail changing vehicle and an on-line welding vehicle is disclosed in the Chinese invention application of 'a construction method for welding the multi-section track section and continuously changing the track section of the rail welding vehicle', which is published in 2015 at 04 and 08 days by southwest traffic university and China railway general office in China and has the publication number of CN 104499390A. The application transports and uninstalls the circuit both sides with the new rail of multistage in advance, welds the rail welding of placing the circuit both sides by the welding railcar under the line, forms continuous long rail, and in changing the new rail that welds well to the heavy rail groove by the rail replacing trolley after that, the heavy rail groove is changed out to old rail, welds the rail that the mouth of a dragon goes out by welding the rail car on the line at last. However, the construction method needs to transport and unload new rails to both sides of the road in advance, and the off-line rail welding vehicle welds the rails in front of the rail replacing vehicle, so that the running speed of the rail replacing vehicle is influenced, the operation efficiency is reduced, and all rail replacing work cannot be completed in the same skylight point.
