Multiple connecting blocks 4041 are fixedly connected to the inner wall of the connecting frame 403. The support tube 4042 is hinged to one end of the connecting block 4041. The plug rod 4043 is movably disposed in the middle of the support tube 4042. Multiple sockets 4044 are equally spaced on the inner wall of the connecting frame 403. The plug rod 4043 is movably connected to the socket 4044. The support spring 4045 is disposed inside the support tube 4042 and its side wall contacts the plug rod 4043. The limiting ring 4046 is fixedly connected to the side wall of the plug rod 4043. The cap 4047 is threadedly connected to one end of the support tube 4042.

[0033] Specifically, such as Figure 2 As shown, a guardrail 6 is fixedly connected to the side wall of the connecting frame 403, and a handrail 7 is fixedly connected to the side wall of the climbing ladder 2.

[0034] Specifically, such as Figure 3 As shown, multiple clips 8 are installed at equal intervals on the side wall of the guardrail 6, and the clips 8 are engaged with the support pipe 4042.

[0035] Specifically, such as Figure 3 As shown, a through hole 9 is provided in the middle of the hook 402, and a positioning bolt 10 is movably provided in the middle of the through hole 9.

[0037] Specifically, such as Figure 4 As shown, a handle 12 is provided in the middle of the insertion rod 4043, and the handle 12 is movably connected to the insertion rod 4043.

[0038] The support frame 1, as the main structure of the entire equipment, achieves flexible movement and positioning through four sets of self-locking casters 3 at the bottom, ensuring convenient use of the equipment in different maintenance sites. The climbing ladder 2 allows maintenance personnel to easily climb to different heights on the truck body for maintenance work. The quick-connect support mechanism 4, through a crossbar 401, hook 402, connecting frame 403, and detachable support assembly 404, enables quick connection and support between the two sets of climbing ladders 2. The hook 402 is movably set in... The connecting frame 403 can be easily attached and detached on the crossbar 401. The connecting block 4041 is hinged to the support tube 4042, and the support tube 4042 can be detached and rotated within the connecting frame 403, which facilitates adjustment of the space in the middle of the connecting frame 403 and allows maintenance personnel to easily inspect the top of the vehicle body. In use, the insert rod 4043 is pulled by the handle 12 to compress the support spring 4045, and then one end of the insert rod 4043 is inserted into the insert hole 4044. At this time, the support tube 4042 is installed and maintenance is complete. Personnel can step on the support tube 4042 when performing maintenance on the roof. When it is necessary to increase the space in the middle of the connecting frame 403, pull the corresponding plug rod 4043 to disengage it from the plug hole 4044, and then the support tube 4042 can be inserted into the locking block 8. The guardrail 6 and the handrail 7 provide additional safety for maintenance personnel. The handrail 7 is fixed to the side wall of the climbing ladder 2 to provide stable support for maintenance personnel during climbing. The positioning bolt 10 in the middle of the hook 402 is used to fix the hook 402 to the crossbar 401. The position of the hook 402 is designed to prevent it from sliding or falling off during operation. The rubber strip 11 at the bottom of the connecting frame 403 prevents the connecting frame 403 from rubbing against the vehicle body during installation. This allows for flexible movement of the climbing ladder 2 and quick installation and connection between the climbing ladder 2 and the connecting frame 403. This enables maintenance personnel to perform maintenance at different positions and heights on the vehicle body, facilitates maintenance personnel climbing to the roof for maintenance, and allows for adjustment of the space in the middle of the connecting frame 403, enabling flexible maintenance by maintenance personnel.

The mounting plate 501 is fixedly connected to the side wall of the support frame 1. The screw 502 is threadedly connected to the middle of the mounting plate 501. The two slide rods 503 are movably disposed in the middle of the mounting plate 501. The connecting plate 504 is fixedly connected to the side wall of the two slide rods 503. One end of the screw 502 is movably connected to the connecting plate 504. The guide wheel 505 is installed at one end of the slide rod 503.

[0040] In use, the screw 502 is rotated according to the distance between the support frame 1 and the vehicle body. The movement of the screw 502 will push and pull the connecting plate 504 to move. The connecting plate 504 drives the slide rod 503 to slide, so that the guide wheel 505 contacts the vehicle body. The two guide wheels 505 can guide the support frame 1 when it moves and protect the vehicle body to prevent the support frame 1 from colliding and rubbing against the vehicle body when it moves.

[0041] By adopting the above technical solution, the problems of existing vehicle body maintenance tooling being too large and unable to move are solved, which prevents maintenance personnel from flexibly moving to inspect different parts of the truck body and from flexibly connecting and assembling maintenance equipment.

[0042] Working Principle: In use, the support frame 1 first achieves flexible movement and positioning through four sets of self-locking casters 3 at the bottom, enabling convenient use in different maintenance sites. The climbing ladder 2 allows maintenance personnel to easily climb to different heights on the truck body for maintenance work. Based on the distance between the support frame 1 and the truck body, rotating the screw 502 causes the connecting plate 504 to move. The connecting plate 504 drives the sliding rod 503 to slide, causing the guide wheel 505 to contact the truck body. The two guide wheels 505 guide the support frame 1 during movement and protect the truck body, preventing collisions and friction between the support frame 1 and the truck body during movement. The connecting frame 403, through hanging... The hook 402 is quickly connected to the two climbing ladders 2. The connecting block 4041 is hinged to the support tube 4042. The support tube 4042 can be disassembled and rotated within the connecting frame 403, which facilitates the adjustment of the space in the middle of the connecting frame 403 and makes it easier for maintenance personnel to inspect the top of the vehicle. When in use, the handle 12 is used to pull the plug rod 4043 to compress the support spring 4045 and retract it. Then, one end of the plug rod 4043 is inserted into the plug hole 4044. At this time, the support tube 4042 is installed. Maintenance personnel can step on the support tube 4042 when inspecting the vehicle roof. When it is necessary to increase the space in the middle of the connecting frame 403, the corresponding plug rod 4043 is pulled out of the plug hole 4044, and then the support tube 4042 is inserted into the locking block 8.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
