[0034] The protection assembly comprises a protective cover 6 located on the outer wall of the welding head 3. The protective cover 6 protects the welding area from external interference and prevents the high temperature and welding smoke generated during welding from polluting the surrounding environment. The protective cover 6 is internally provided with a plurality of holes for air circulation to ensure temperature control inside the protective cover 6 and prevent component damage due to heat accumulation. The design of the holes allows air to flow freely, effectively removing the hot air and smoke generated during welding, improving the comfort and safety of the working environment. The protective cover 6 is fixedly connected with support blocks 5 on both sides of the top, each support block 5 is fixedly connected with a connecting disc 7 on the top, each connecting disc 7 is fixedly connected with a connecting column 8 on the top, each connecting column 8 is fixedly connected with an arc-shaped clamping block two 10 on the top, the arc-shaped clamping block two 10 cooperates with the clamping column 11 to provide more stable positioning function, ensuring accurate docking and fixing of related components, preventing structural loosening or displacement, and improving the reliability of the overall device. Each connecting column 8 is slidably connected with an arc-shaped clamping block one 9, and the pipeline welding vehicle 1 is fixedly connected with a plurality of fixed shells one 4. Each fixed shell one 4 is fixedly connected with a fixed column 12 on the inner wall of both sides, and each fixed column 12 is slidably connected with a clamping column 11 on the outer wall. The clamping column 11 is engaged with the arc-shaped clamping block two 10 to achieve precise positioning between components through sliding connection. The adjacent clamping columns 11 and the arc-shaped clamping block two 10 are engaged on the outer wall. Each fixed column 12 is provided with a spring 14 on the outer wall. One end of each spring 14 is fixedly connected to the outer wall of the clamping column 11, and the other end of each spring 14 is fixedly connected with a fixed ring 13. The fixed ring 13 provides a fixed point for the spring 14, allowing the spring 14 to work normally while preventing displacement or falling of the spring 14. Each fixed ring 13 is fixedly connected to the outer wall of the fixed column 12 on the inner wall;
[0035] Specifically, during the use of the device, when the welding head 3 welds the pipe wall, high-temperature particles and debris generated by welding will splash out due to high temperature. If these high-temperature particles and debris are not effectively blocked, they will cause damage to the inside of the device and pose a threat to the health of the surrounding workers, especially after the fine particles are inhaled into the lungs, causing health problems. Therefore, effective protection by the protective cover 6 is particularly important, which can effectively block the high-temperature particles and debris generated during the welding process to prevent them from splashing into the device, thereby avoiding device failure or damage. At the same time, the design of the protective cover 6 also takes into account the safety of the workers, which can prevent fine particles from being inhaled into the air, reducing the potential threat to the health of the workers. The protective cover 6 is provided with a plurality of holes, which not only help the gas to circulate to ensure smooth airflow inside and outside the protective cover 6, but also avoid overheating problems caused by excessive sealing. During the long-term use of the protective cover 6, a large amount of welding impurities will adhere to its inner wall, which needs to be cleaned regularly to ensure the protection effect and normal operation of the device. When the protective cover 6 needs to be cleaned, it can be removed from the device by pulling it. At this time, the protective cover 6 moves by the cooperation of the supporting block 5 and the connecting disc 7, which drives the arc-shaped clamping block two 10 at one end of the connecting column 8 to move to the top. The connecting disc 7, through its structural characteristics, pushes the arc-shaped clamping block one 9 into contact with the inclined surface of the clamping column 11, which promotes the clamping column 11 to slide along the outer wall of the fixed column 12, thereby promoting the compression of the spring 14. With the movement of the outer wall of the arc-shaped clamping block one 9, the clamping column 11 gradually slides downward until the outer wall of the arc-shaped clamping block one 9 contacts the top of the clamping column 11. When the protective cover 6 is pulled down at this time, the connecting column 8 drives the arc-shaped clamping block two 10 to coincide with the arc-shaped clamping block one 9. The cooperation of the outer walls of the two further enhances the cooperation with the clamping column 11, making it difficult for the clamping column 11 to effectively fix the arc-shaped clamping block two 10 on its plane, making the disengagement of the clamping column 11 and the arc-shaped clamping block two 10 more smooth, thereby achieving the disassembly of the protective cover 6. After the cleaning work is completed, the protective cover 6 can be reinstalled by moving the arc-shaped clamping block two 10 to the side of the clamping column 11, and using the rebounding force of the spring 14 to push the clamping column 11 to firmly clamp the arc-shaped clamping block two 10, thereby achieving the quick and convenient installation of the protective cover 6. This process not only simplifies the installation and disassembly operation of the protective cover 6, but also improves the protection of the device and the convenience of the workers. The design of the protective cover 6 and its related components effectively improves the safety and convenience of the device, and also optimizes the maintenance and cleaning process. Through the ingenious mechanical structure, the high-temperature particles and debris generated during the welding process are effectively isolated, ensuring the normal operation of the device and the health of the personnel.

Each sliding strip 21 is slidably connected with an arc-shaped fixed block 22, and the arc-shaped fixed block 22 is fixedly connected with a connecting plate two 24 on one side. The connecting plate two 24 is rotatably connected with a fixed shaft 23 inside, which is used to provide support for the rotation of the cleaning brush and ensure that the cleaning brush 25 can rotate freely and effectively clean the surface of the pipe. The fixed shaft 23 is fixedly connected to the inside of the fixed shell two 18. The connecting plate two 24 is fixedly connected with a cleaning brush 25 on one side. The cleaning brush 25 is used to effectively remove the dirt or impurities attached to the surface by directly contacting the surface of the pipe with the brush part, thereby improving the cleanliness of the pipe and ensuring the quality of the pipe during subsequent welding or processing.
[0037] Specifically, during the movement of the equipment, first start the motor 17, drive the connecting block one 19 to rotate through the output end of the motor 17, the rotating action of the connecting block one 19 further drives the connecting block two 20 to move, so that the sliding strips 21 on both sides of the connecting block two 20 move, the movement of the sliding strips 21 is transmitted to the connecting plate two 24 through the arc-shaped fixed block 22, and the connecting plate two 24 reciprocates left and right with the fixed shaft 23 as the center. With the swinging of the connecting plate two 24, the cleaning brush 25 also sweeps on the outer wall of the pipe wall. The effect of this sweeping process is mainly to remove the dust particles attached to the outer wall of the pipe wall, thereby avoiding the negative influence of these dust and impurities on the adsorption effect between the magnetic wheel 2 and the pipe wall. Through the continuous operation of the cleaning device, the contact between the magnetic wheel 2 and the pipe wall can be ensured to be more closely and stably, the adsorption performance and working efficiency of the equipment during movement are improved, the stability of the equipment during movement is enhanced, and the movement task of the equipment can be smoothly and efficiently completed.
