[0049] Walking status:

[0050] 1. When the rail replacement vehicle is in motion, all working devices are retracted, and the rail replacement vehicle travels to the construction site via bogie 3.

[0051] Track changing operation status:

[0052] 1. During the track replacement operation, the track replacement vehicle travels to the construction site. Before carrying out the track replacement operation, the on-site personnel remove the fasteners and cut off both ends of the old rail.

[0053] 2. When the rail replacement operation is underway, the rail replacement vehicle will travel to the construction site and carry out the rail replacement operation. Before that, the new rails need to be unloaded to the center of the track or the side of the track.

[0054] 3. During track replacement operations, the track replacement vehicle travels to the construction site, refer to... Figure 5 As shown, when the rail-changing vehicle moves to one end of the old rail, the robotic arm pulls the old rail out of the rail-bearing groove and pulls the new rail into the rail-bearing groove. The rail-changing vehicle moves at low speed, continuously pulling out the old rail and replacing it with the new rail.

[0055] 4. During the rail replacement operation, the rail replacement vehicle travels to the construction site and continuously performs rail replacement operations. After the rail replacement operation is completed, the on-site personnel install fasteners and weld the two ends of the new steel rail to complete the rail replacement operation.

[0056] Track winding operation status:

[0057] 1. During the track collection operation, after the track replacement vehicle completes the track replacement operation, it can be coupled with the track storage vehicle and travel to the construction site to carry out the track collection operation;

Through the rail lifter, the rail clamps are guided into the guide device at the rear of the rail-changing vehicle. The rail-changing vehicle moves and continuously picks up the old rails, completing the rail-collecting operation.

[0059] Rescue operation status:

[0060] 1. During rescue operations, if the track-changing vehicle derails or encounters an emergency while in a confined space such as a subway or tunnel, the rescue devices at both ends of the track-changing vehicle will lift the vehicle body. (See also...) Figure 7 As shown, the vehicle's position was readjusted to remove it from a dangerous position.
