In this embodiment, before the rear trolley 200 carries the old track 300 and guides the old track 300 to be replaced to the track center or the ballast shoulder, and before the trolley 200 carries the old track 300 and conveys the old track 300 to the front trolley 100, that is, after the second step and/or before the third step, the following steps are further included:

the old rail 300 is hoisted to the rear trolley 210 using a crane or hoisting equipment.

In this embodiment, before the front trolley 100 carries the new track 400 and guides the new track 400 into the target installation position, the method includes the following steps:

(1) Before rail replacement operation, removing fasteners on the old rail 300 on the construction section through an operation train or manually;

(2) The front trolley 100 and the rear trolley 200 are accommodated in a rail-changing train carriage, and after reaching the working position along with the working train, the front trolley 100 and the rear trolley 200 are unloaded onto the old rail 300 to be replaced, and the front trolley 100 and the rear trolley 200 are sequentially arranged from front to back.

The application utilizes loop wheel machine or lifting device to hoist old track 300 to back dolly 210, includes following step:

when the rail is replaced, the rear end of the old rail 300 to be replaced is lifted to the old rail guide chute 226 of the rear trolley 200 by using a crane or lifting equipment, the old rail guide device 220 moves forwards longitudinally, and the old rail guide chute 226 stretches out to receive the rear end of the old rail 300 to be replaced;

in this embodiment, the rear cart 200 carries the old track 300 and conveys the old track 300 to the front cart 100, and further includes the following steps:

when the old rail 300 passes through the old rail guide 220, rubber pads adhered to the rail bottom of the old rail 300 are removed by the rail bottom glue removing device (223).

The application can cooperate the track transport vechicle to realize orbital "in order to unload the substitution", new track is unloaded from the operation train, and the front dolly 100 directly falls into target mounted position, and the construction method of changing rails is simpler.

The rear cart 200 can recover the old track 300 to the center of the track, avoiding the track crossing phenomenon.

The rail replacement and recovery operation can be flexibly carried out according to actual conditions, the skylight time is fully utilized, rail replacement mechanization is realized, the operation pressure of constructors is reduced, and the construction efficiency is improved.
