A filter box 11 is fixedly connected to one end of the connecting hose 10, and the filter box 11 is fixedly connected to the inner wall of the workbench 1. A filter box 12 is slidably connected inside the filter box 11. An air pump 13 is fixedly connected to one side of the outer wall of the filter box 11, and the output end of the air pump 13 is arranged inside the workbench 1; the cleaning component 8 includes an arc box 801, the arc box 801 is fixedly connected to the output end of the hydraulic rod 7, one side of the outer wall of the arc box 801 is fixedly connected to one end of the connecting tube 9, and one side of the inner wall of the arc box 801 is fixedly connected to a plurality of suction nozzles 802;

[0031] Specifically, by starting the electric push rod 3, the sliding plate 4 is raised and lowered, and then the sliding plate 4 is used to drive the welding head 5 to contact the pipe connection for welding. Then, the pipe is rotated to complete the welding work. Then, by starting the air pump 13, a negative pressure is formed inside the filter box 11. Through the connecting hose 10, the air inside the connecting pipe 9 is extracted, and the inside of the arc box 801 is extracted through the connecting pipe 9. Welding debris and harmful gases are collected into the filter box 12 through the suction nozzle 802. An activated carbon filter plate is placed inside the filter box 12 to filter harmful gases, and the hollow net inside collects debris. This series of steps ensures the completion of high-precision welding operations. Finally, by starting the hydraulic rod 7, the cleaning component 8 can be driven to adjust according to the pipe diameter.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The upper surface of the workbench 1 is fixedly connected with a left-right symmetrical slide rail 14, and the outer wall of the slide rail 14 is slidably connected with a sliding plate 15, and the upper surface of the sliding plate 15 is fixedly connected with a fixture 16; one side of the outer wall of the workbench 1 is fixedly connected with a motor 17, and the output end of the motor 17 is fixedly connected with a screw rod 18; the outer wall of the screw rod 18 is threadedly connected with a threaded sleeve 19, and the outer wall of the threaded sleeve 19 is rotatably connected with a left-right symmetrical connecting rod 20; one side of the outer wall of the connecting rod 20 is rotatably connected with a connecting frame 21, and the connecting frame 21 is slidably connected to the inner wall of the workbench 1; the upper surface of the connecting frame 21 is fixedly connected to the lower surface of the sliding plate 15; a plurality of universal wheels 22 are arranged on the lower surface of the workbench 1, and a left-right symmetrical protective door 23 is rotatably connected inside the workbench 1;

[0033] Specifically, during the installation process, two sections of the pipe are placed between the clamps 16, and the clamps 16 are started to clamp the pipes according to their different diameters. The clamp 16 has jaws that extend in opposite directions or in the horizontal direction. This common structure does not require much explanation of its working principle. Next, the motor 17 is started to rotate the screw 18, driving the connecting rod 20 to slide the outer wall of the threaded sleeve 19. The movement of the connecting rod 20 drives the connecting frame 21 to slide inside the workbench 1, and then controls the sliding plate 2 15 to slide on the outer wall of the slide rail 14. Through such a mechanism, the stable alignment of the two sections of the pipe is ensured. This process improves the accuracy and efficiency of pipeline installation through simple and effective power transmission.

[0034] Working principle: When welding is required using a welding device, two sections of pipes are placed between the clamps 16, and the clamps 16 are started to clamp the pipes according to different diameters. It should be noted that the clamps 16 have jaws extending in opposite directions or in the horizontal direction. This structure is relatively common, and its working principle is not described in detail here. Secondly, the motor 17 is started to drive the screw rod 18 to rotate, thereby driving the connecting rod 20 on the outer wall of the threaded sleeve 19 to slide. At this time, the connecting rod 20 drives the connecting frame 21 to slide inside the workbench 1. At this time, the connecting frame 21 drives the sliding plate 15 to slide on the outer wall of the slide rail 14, thereby driving the two sections of pipes to be stably aligned.

[0035] Secondly, when the pipeline is aligned, the sliding plate 4 is raised and lowered by starting the electric push rod 3. At this time, the welding head 5 is driven by the sliding plate 4 to contact the pipeline connection for welding operation. The pipeline is rotated to achieve the effect of welding the pipeline. At this time, the air pump 13 is started to form a negative pressure inside the filter box 11. At this time, the air inside the connecting pipe 9 is extracted through the connecting hose 10. At this time, the inside of the arc box 801 is extracted through the connecting pipe 9. At this time, welding debris and harmful gases are collected into the filter box 12 through the suction nozzle 802. The harmful gases can be filtered by placing an activated carbon filter plate inside the filter box 12, and the debris can be collected by the hollow net inside the filter box 12, thereby achieving the effect of high-precision welding operation. By starting the hydraulic rod 7, the cleaning component 8 can be driven to adjust according to the pipeline diameter.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
