[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The present invention uses multiple, for example three, track-changing devices at the same time. Figure 2 Figure 3 , the new rails can be installed while the old rails are lifted, achieving synchronous operation. This greatly improves the speed and efficiency of the rail replacement process. The positions of the upper rail guide frame and the lower rail guide frame are designed to allow flexible adjustment of their positions according to construction needs, as well as quick disassembly and assembly through latches, allowing the equipment to adapt to different working environments and requirements more quickly.
[0017] 2. The present invention ensures accurate guidance and stable support of the rails during the replacement process through a multi-stage guide wheel system, can accurately locate the position of the new rails, reduces the risk of deviation of the new rails, and improves the safety of the entire process. The multi-stage guide wheel system includes a first guide wheel, a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel. A rail locking mechanism is used to lock the rails, which reduces manual intervention, simplifies the operating process, reduces the labor intensity of workers, and also reduces the possibility of human error. The design takes the elastic deformation of the rails into consideration and cleverly utilizes this elastic deformation characteristic to arrange the construction position of the device, so that the device is in the best construction position, assists in the bending and replacement of the old and new rails, and enables the device to better adapt to the rail replacement needs under different specifications and conditions.

[0033] When replacing old rails with new rails, the rail replacement method includes the following steps:
[0034] S1. Prepare three light railway continuous rail changing devices, which are divided into car No. 1, car No. 2 and car No. 3. Car No. 1 and car No. 3 have the same structure. The upper rail guide frame 3 of car No. 1 and car No. 3 is located on the outside of the lower rail guide frame 4, and the upper rail guide frame 3 of car No. 2 is located on the inside of the lower rail guide frame 4 to assist in the replacement of new and old rails;
[0035] S2, arrange the No. 1 car, No. 2 car and No. 3 car in a smooth manner and install them on the new rails and the old rails;
[0036] S3, the old rail is installed on the lower rail guide frame 4 of car No. 1, and installed on the upper rail guide frame 3 of cars No. 2 and No. 3 to achieve the lifting of the old rail;
[0037] S4, the new rail is installed on the upper rail guide frame 3 of car No. 1 to assist the new rail to enter the installation position, and is installed on the lower rail guide frame 4 of cars No. 2 and No. 3, so that the old rail is lifted and the new rail is installed on the position of the old rail. Since the rail is elastic, the new rail can be installed and the old rail can be removed simultaneously by bending the new rail and the old rail, thereby improving the maintenance efficiency of the railway;
[0038] S5, when the upper rail guide frame 3 is working, the latch 8 is first pulled out, the rotating frame 6 is lifted upward, and then the rail is placed on the third guide wheel 10, the third guide wheel 10 supports the rail, the second guide wheel 9 contacts the left and right sides of the rail to limit the position, and after the placement is completed, the rotating frame 6 and the latch 8 are reset, and the first guide wheel 7 limits the top of the rail;
