[0049] Referring to Figure 1 and Figure 6 , the outer periphery of the second platform module 2 is provided with a first safety fence 21, and the outer periphery of the third platform module 3 is provided with a second safety fence 33. The first safety fence 21 and the second safety fence 33 can ensure the safety of the personnel, and prevent the personnel from falling accidentally.

[0050] Referring to Figure 3 and Figure 6 , the platform carrying beam frame 1 comprises a support vertical beam 11, the lower end of the support vertical beam 11 is supported on the foundation platform, the upper end of the support vertical beam 11 is provided with a first horizontal beam 12, the second platform module 2 is installed on the first horizontal beam 12, ensuring that the second platform module 2 extends horizontally and is firmly installed, the first horizontal beam 12 is provided with a support inclined beam 13, the support inclined beam 13 extends upward and is connected with a second horizontal beam 14, the third platform module 3 is installed on the second horizontal beam 14, ensuring that the third platform module 3 extends horizontally and is firmly installed.

[0051] Further, the platform carrying beam frame 1 further comprises a door-shaped frame 15, which is arranged above the second horizontal beam 14 to avoid the bogie 101 of the train 100 to be maintained. The space inside the door-shaped frame 15 can accommodate the bogie 101 to pass through, so that the train 100 to be maintained can smoothly drive to the designated maintenance position. In addition, the arrangement of the door-shaped frame 15 can improve the strength and carrying capacity of the entire platform carrying beam frame 1, and avoid the deformation of the platform carrying beam frame 1 due to overload.

[0056] Further, referring to Figure 1 and Figure 2 , each maintenance track further comprises a connecting track beam 8. The two three-layer platform modules 3 in a single maintenance track are in butt joint through the connecting track beam 8, so that there is a certain distance between the two maintenance points, avoiding the distance between the two trains to be maintained being too close, and preventing collision when the two trains enter the maintenance track. The middle part of the connecting track beam 8 is provided with at least one platform bearing beam frame 1 to ensure the stability of the support of the connecting track beam 8.
