A horizontal adjustment device 9 is installed on one side of the vertical adjustment device 8. The height of the horizontal adjustment device 9 can be adjusted through the vertical adjustment device 8. A chuck 10 is installed on one side of the horizontal adjustment device 9. The chuck 10 is used to fix a welding gun connected to a welding machine 25. The welding gun is an automatic feeding method. The target line of the welding machine 25 overlaps the blocking door frame. The front and rear of the chuck 10 can be adjusted through the horizontal adjustment device 9. When in use, fix the welding gun on the clamp 10, move the device to the side of the blocking door frame to be welded, make the forward direction of the trolley 1 consistent with the direction of the welding seam, move the clamp 10 back and forth through the horizontal adjustment device 9, align the bottom end of the welding gun with the welding seam, and lower the height of the horizontal adjustment device 9 through the vertical adjustment device 8, and then the height of the welding gun is lowered until the bottom end of the welding gun is at a certain height (8mm or more) from the welding seam. When welding, the welding machine 25 is powered on, the electromagnet 7 is powered on, and the first magnet 7 is powered on to attract the support plate 4, so that it descends along the guide rod 5, and further compresses the second A spring 6 is used until the bottom of the support plate 4 contacts the top of the electromagnet 7, and the support plate 4 no longer descends. When the support plate 4 descends, the welding gun is driven to further descend through the vertical adjustment device 8, the horizontal adjustment device 9 and the clamp 10, so that the bottom end of the welding gun is closer to the weld (reaching the welding distance), and then the weld is welded, pushing the trolley 1 to move, and then continuously welding the weld at the same height, and the welding quality is more stable. After welding is completed, the electromagnet 7 is powered off, so that the welding gun rises and resets under the action of the compressed first spring 6, and the bottom end of the welding gun is away from the weld, and welding stops.

The welding operation can be conveniently performed on the blocked door frame. The workers have low labor intensity and are not easily fatigued. The distance between the welding gun and the weld is stable, and the welding quality is more stable and controllable.

[0030] Embodiment 2:

[0031] like Figure 1-3As shown, two front wheels 2 and two steering wheels 3 are installed at the bottom of the trolley 1, and a scraper 11 is installed on one side of the front wheel 2. The scraper 11 is used to scrape off the debris stuck on the front wheel 2, so that the height of the trolley 1 close to the chuck 10 can be kept as stable as possible during movement, thereby keeping the distance between the bottom end of the welding gun and the weld stable, and the quality of the weld is more uniform and controllable.

[0032] Two front wheels 2 and two steering wheels 3 are installed at the bottom of the trolley 1, and a scraper 11 is installed on one side of the front wheel 2. The scraper 11 is used to scrape off the debris stuck on the front wheel 2, so that the distance between the bottom end of the welding gun and the weld is kept stable during the welding process.

[0033] Embodiment 3:

[0034] like Figure 1-3 As shown, a handle 12 is installed on the top of the trolley 1, and a switch 18 is installed on one side of the handle 12. The switch 18 is connected to the electromagnet 7. When in use, the handle 12 is held to conveniently push the trolley 1 to move. By pressing the switch 18 installed on the side of the handle 12, the power on and off of the electromagnet 7 can be conveniently controlled. Therefore, only one hand is required to hold the handle 12 to control the movement of the trolley 1 while controlling the power supply of the electromagnet 7, which is more convenient to use.

[0036] Embodiment 4:

[0037] like Figure 1-3 and Figure 5 As shown, a connecting plate 13 is installed on one side of the trolley 1, a bolt 14 is installed on the connecting plate 13, a nut is installed on the bolt 14, an adjusting plate 15 is installed on the bolt 14, a connecting rod 16 is installed between the adjusting plate 15 and the scraper 11, the connecting rod 16 passes through the connecting plate 13, and its two ends are connected to the adjusting plate 15 and the scraper 11. When in use, the nut is rotated to make the adjusting plate 15 approach the connecting plate 13, and then the scraper 11 is driven to approach the front wheel 2 through the connecting rod 16, thereby adjusting the distance between the scraper 11 and the front wheel 2.

[0038] By providing the connecting plate 13 , the bolt 14 , the adjusting plate 15 and the connecting rod 16 , the distance between the scraper 11 and the front wheel 2 can be conveniently adjusted.

[0039] Embodiment 5:

[0040] like Figure 5As shown, the connecting rod 16 is a boss structure formed by connecting two sections of cylinders with different diameters. The end of the connecting rod 16 with a thicker diameter is fixedly connected to the tube 11, and the other end of the connecting rod 16 passes through the adjusting plate 15. A second spring 17 is sleeved on the outer circle of the end of the connecting rod 16 with a smaller diameter. When in use, the adjusting plate 15 is close to the connecting plate 13, thereby compressing the second spring 17. The second spring 17 pushes the connecting rod 16 to move, thereby making the scraper 11 close to the front wheel 2 until it is pressed on the front wheel 2, so that the scraper 11 can completely scrape off the debris on the front wheel 2. By controlling the compression degree of the second spring 7, the pressure value between the front wheel 2 and the scraper 11, that is, the friction force, can be controlled. The scraper 11 can play a soft braking role, so that the trolley 1 has a certain forward resistance during the movement, to prevent the forward resistance of the trolley 1 from being too small, resulting in an uncontrollable moving speed.

[0041] By providing a connecting rod 16 with a boss structure and installing a second spring 17 on the connecting rod 16 , soft braking of the trolley 1 can be achieved, which facilitates controlling the moving speed of the trolley 1 and helps to scrape off debris on the front wheel 2 .

[0042] Embodiment 6:

[0043] like Figure 1-4 As shown, a ruler 19 and a bogie 20 are installed on one side of the trolley 1. The ruler 19 is fixedly connected to the trolley 1. The bogie 20 is T-shaped as a whole and is rotatably connected to the trolley 1. Its two ends are connected to the steering wheel 3. A limit frame 21, a pointer 22 and a pull rod 23 are installed on the bogie 20. The scale value of the ruler 19 aligned with the pointer 22 is the steering angle of the current steering wheel 3. One end of the pull rod 23 passes through the bogie 20 and is connected to the limit frame 21. A third spring 24 is sleeved on the pull rod 23. When in use, the pull rod 23 is pulled. The limit frame 21 is separated from the scale 19 and the third spring 24 is compressed. At this time, the bogie 20 can be rotated to adjust the angle of the steering wheel 3, and the scale value reading of the alignment of the scale 19 and the support 22 is observed. When the set angle is reached, the pull rod 23 is released. Under the action of the third spring 24, the limit frame 21 is pressed tightly against one side of the scale 19, and then the bogie 20 is fixed. At this time, there is an angle difference between the front wheel 2 and the rear wheel 3, and the forward route of the trolley 1 is an arc. The curvature of the arc is consistent with the curvature of the weld, which can facilitate the welding of arc-shaped welds.

[0044] By arranging the scale 19, the bogie 20, the limit frame 21, the pointer 22, the pull rod 23 and the third spring 24, the angle of the steering wheel 3 can be conveniently adjusted so that the device can process an arc-shaped weld.

[0045] Working principle: When in use, fix the welding gun on the clamp 10, move the device to the side of the blocked door frame to be welded, make the forward direction of the trolley 1 consistent with the direction of the welding seam, move the clamp 10 back and forth through the horizontal adjustment device 9, align the bottom end of the welding gun with the welding seam, and lower the height of the horizontal adjustment device 9 through the vertical adjustment device 8, and then the height of the welding gun is lowered until the bottom end of the welding gun is at a certain height from the welding seam. When welding, the welding machine 25 is powered on, the electromagnet 7 is powered on, and the magnet 7 is powered on to attract the support plate 4, so that it descends along the guide rod 5 and further compresses it. The first spring 6 is pressed until the bottom of the support plate 4 contacts the top of the electromagnet 7, and the support plate 4 no longer descends. When the support plate 4 descends, the welding gun is driven to further descend through the vertical adjustment device 8, the horizontal adjustment device 9 and the clamp 10, so that the bottom end of the welding gun is closer to the weld, and then the weld is welded, pushing the trolley 1 to move, and then continuously welding the weld at the same height, and the welding quality is more stable. After welding is completed, the electromagnet 7 is powered off, so that the welding gun rises and resets under the action of the compressed first spring 6, and the bottom end of the welding gun is away from the weld, and welding stops.
