Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This specific embodiment is a welding device for the side panel of a car cargo box, and its structural schematic diagram is shown below. Figure 1 , Figure 2 As shown, the assembly includes a movable box 1, a fixed frame 3, a welding torch 2, and a ladder 4. The movable box 1 and the fixed frame 3 are fixedly connected to each other. The welding torch 2 is movably inserted into the upper surface of the movable box 1, and a connecting pipe 5 is provided at the bottom of the welding torch 2. The connecting pipe 5 passes through the interior of the movable box 1 and connects to the welding power source. The ladder 4 is movably installed inside the fixed frame 3. The ladder 4 has an inverted U-shaped structure and is slidably connected to the fixed frame 3. Support rods 7 are provided on the surfaces of the ladder 4 and the fixed frame 3 adjacent to each other, and multiple sets of support rods 7 are horizontally spaced. The bottom of the movable box 1 and the fixed frame 3 are respectively provided with pulleys, and brake pads are installed on the pulleys.

[0018] Reference Figure 3 The fixing frame 3 has a vertically oriented inner groove 8 on its surface facing the ladder 4. A sliding rod 6 protrudes from the outer wall of the ladder 4 and slides into the inner groove 8. The fixing frame 3 has a U-shaped structure, and a drive motor 10 is fixedly installed in the center of its inner side. A vertically oriented drive screw 9 is connected to the drive motor 10.

[0019] Reference Figure 4 A rotating column 12 is vertically installed on the inner wall of the top of the ladder 4. The rotating column 12 has a threaded hole inside and is threadedly connected to the drive screw 9. An installation groove 11 is provided on the inner side wall of the ladder 4, and the support rod 7 is fitted into the installation groove 11.

[0020] Working principle: The device is equipped with pulleys at the bottom, and brake pads are mounted on the pulleys. Before welding the side panels of the truck bed, the operator can push the device and use the pulleys to move it to the appropriate welding position. Once it reaches the designated position, the operator can depress the brake pads to fix the device in place, preventing it from moving during the welding process and ensuring the stability of the welding.

[0021] A welding torch 2 is movably inserted into the upper surface of the mobile box 1. The bottom of the welding torch 2 is equipped with a connecting pipe 5, which passes through the interior of the mobile box 1 and connects to the welding power source. After the device is positioned, the operator removes the welding torch 2 from the mobile box 1. At this time, the welding torch 2 is connected to the welding power source inside the mobile box 1 through the connecting pipe 5, and welding operations can be performed at any time, preparing for subsequent welding work.

[0022] The worker first climbs onto ladder 4. The movable inner rod of ladder 4 is located inside the fixed frame 3, forming an inverted U-shape and slidably connected to it. The fixed frame 3 is U-shaped, with a drive motor 10 fixedly mounted in the center of its inner side. The drive motor 10 is connected to a vertically positioned drive screw 9. A rotating column 12 is vertically mounted on the inner wall of the top of ladder 4. The rotating column 12 has a threaded hole inside, which is threadedly connected to the drive screw 9. When the height of ladder 4 needs to be adjusted according to the height of the cargo box side panel, the drive motor 10 is started. The drive motor 10 drives the drive screw 9 to rotate. Because the rotating column 12 is threadedly connected to the drive screw 9, under the action of the thread, the rotating column 12 moves up and down along the drive screw 9, thereby causing ladder 4 to slide up and down within the fixed frame 3, achieving the height adjustment of ladder 4. Meanwhile, the fixed frame 3 has an inner groove 8 vertically opened on the surface facing the ladder 4, and a slide rod 6 protrudes from the outer wall of the ladder 4. The slide rod 6 is inserted into the inner groove 8 and slides. This design ensures the stability of the ladder 4 during the up and down sliding process and prevents the ladder 4 from shaking.

[0023] The ladder 4 and the fixed frame 3 are adjacent to a plurality of horizontally spaced support rods 7. An installation groove 11 is provided on the inner wall of the ladder 4, and the support rods 7 are fitted into the installation groove 11. When the ladder 4 is adjusted to a suitable height, the support rods 7 provide auxiliary support, offering a more stable standing platform for the operator. The operator stands on the ladder 4 and uses a welding torch 2 to weld the side panel of the truck cargo box. During welding, the height of the ladder 4 can be adjusted as needed to accommodate welding requirements at different positions. The ladder can also be moved with worker assistance during welding; after repositioning, the brake pads can be pressed firmly.

[0024] After the welding operation is completed, the operator stops the drive motor 10, puts the welding torch 2 back into the movable plug-in position on the upper surface of the moving box 1, then starts the drive motor 10 to make the drive screw 9 rotate in the opposite direction, driving the ladder 4 down to the initial position, and finally releases the brake pads to push the device away from the welding site.
