Please refer to Figures 1 - 2 and Figure 14 , the cantilever crane 3 can be manually controlled to lift heavy materials and assist manual assembly work.

[0041] The present utility model streamlines the disassembly process through the movable working platform 1. Moving to one station completes one process. The staff can operate on the platform, and moving to a position completes one disassembly device. The corresponding processes at each position are carried out. Disassembly and inspection are independent and separated, and carried out synchronously. The working platform 1 is driven by steering wheels and can run omnidirectionally. It can be scheduled and controlled by the upper computer, is more flexible, and can achieve full-automatic intelligent unmanned operation. When disassembling heavy components, they can be lifted by the cantilever crane 3, such as wheel sets, motors, etc. Without the intervention of the overhead crane, the degree of freedom is higher and it is more flexible. The purpose of the present utility model is to concentrate the disassembly process on one platform to form a pulsating line for transfer operations. The staff stands on the platform to carry out various operations to form an assembly line, greatly improving production efficiency.

[0042] Please refer to Figures 1 - 2 and Figures 6 - 7, the first protection component 4 includes a bearing plate 41, a first protection plate 42, a second protection plate 43 and a linear drive component 44.

[0051] Please refer to Figure 9 and Figure 15 . After the second protection plate 43 approaches the jib crane 3, the first electric telescopic rod 452 extends, driving the baffle plate 451 to move outside the third assembly groove 433. The cross-sectional shape of the baffle plate 451 is a right triangle, and the baffle plate 451 can fill the missing corner of the second protection plate 43, further expanding the protection range of the second protection plate 43.

[0052] Embodiment 4

[0053] Based on Embodiment 3, please refer to Figure 1 , Figure 3 , Figure 10 and Figure 12 . The present utility model further includes a second protection assembly 5.

Both of the two second supplementary components 523 are arranged in the first assembly cavity 5211 and are mirror-symmetrical in structure.

[0056] Please refer to Figures 14 - 15 , the length of the first cross bar 521 is the same as the width of the working platform 1. Therefore, the end of the first cross bar 521 will not extend above the bearing plate 41. When the cantilever crane 3 hoists the bogie 8, the bogie 8 will not collide with the second protective fence 52. For this reason, when the second protective plate 43 approaches the cantilever crane 3, there will be a gap between the second protective fence 52 and the second protective plate 43. The second supplementary component 523 can form an obstacle at this gap to prevent the staff from falling from the gap.

[0057] Please refer to Figures 10 - 11 , the second supplementary component 523 includes a second electric telescopic rod 5231, an assembly plate 5232, a first elastic strap 5233 and a second elastic strap 5234. Please refer to Figure 10 and Figure 14 , when the cantilever crane 3 hoists the bogie 8, the second supplementary component 523 is in a retracted state, the second electric telescopic rod 5231 shortens, and both the first elastic strap 5233 and the second elastic strap 5234 are retracted in the first assembly cavity 5211. Please refer to Figure 11 and Figure 15 , when the second protective plate 43 approaches the cantilever crane 3, the second supplementary component 523 changes to a use state, the second electric telescopic rod 5231 extends, and the first elastic strap 5233 and the second elastic strap 5234 are pushed out of the first assembly cavity 5211 through the assembly plate 5232. Since only one end of both the first elastic strap 5233 and the second elastic strap 5234 is fixed to the assembly plate 5232, the staff can tie the first elastic strap 5233 to the baffle 451 and tie the second elastic strap 5234 to the second protective plate 43.

The jib crane 3 will lift the bogie 8 to the side of the third protective fence 53 away from the step 11. Therefore, the staff must bypass the third protective fence 53 to disassemble the bogie 8. Therefore, the third protective fence 53 can prevent the staff from falling from the step 11. The length of the second cross bar 531 is the same as the width of the working platform 1. Therefore, the end of the second cross bar 531 will not extend above the bearing plate 41, and the staff has enough space when bypassing the third protective fence 53 and will not collide with the working platform 1.

[0062] Please refer to Figure 14 , when the jib crane 3 lifts the bogie 8, the staff can stand on the side of the third protective fence 53 away from the jib crane 3 and block the spaces on both sides of the third protective fence 53 through the movement limiting components 533 to prevent the staff from approaching the bogie 8 during the lifting process and prevent the bogie 8 from accidentally falling and injuring the staff.

[0063] Please refer to Figures 12 - 14 , the movement limiting component 533 includes a slide bar 5331 and a handle 5332. A chute 5311 is provided at the top of the second cross bar 531.

The width of the chute 5311 is greater than the distance between the second cross bar 531 and the second protective plate 43, and the length of the slide bar 5331 is the same as the width of the chute 5311. Therefore, when the slide bar 5331 moves towards the side close to the second protective plate 43, it can contact the second protective plate 43.

[0064] Please refer to Figure 7 and Figure 14, jacks are provided on the side wall of the second protective plate 43. When the cantilever crane 3 hoists the bogie 8, the staff holds and pushes the handle 5332 to move outward. While the handle 5332 slides along the outer surface of the second cross bar 531, it drives the sliding rod 5331 to slide outward along the chute 5311. The sliding rod 5331 is inserted into the jack on the second protective plate 43 to prevent the staff from moving to a position close to the bogie 8.

[0065] Please refer to Figure 1 and Figure 14 , two first protective fences 51, the third protective fence 53 and two first protective plates 42 jointly enclose to form two moving channels 6. Both of the two moving channels 6 are in an L-shaped structure and are mirror-symmetrical in structure. After the staff climbs onto the step 11, they can bypass the third protective fence 53 through the moving channel 6. When the cantilever crane 3 hoists the bogie 8, that is, when the staff is blocked by the movement restriction assembly 533, they can be jointly protected by the first protective fence 51, the third protective fence 53 and the first protective plate 42, and the staff will not fall from the edge of the working platform 1 or the step 11.
