[0002] With the vigorous development of the petrochemical industry, the pipeline system, as an important component, plays an irreplaceable role in transporting fluid media. In the construction process of the pipeline system, the welding quality of the pipeline interface is directly related to the safety and stability of the entire system. However, in the traditional welding process, since the pipeline needs to be manually rotated to adjust the position of the welding point, this operation method is often affected by human factors, resulting in inaccurate welding point positions, which in turn affects the welding quality and the stability of the pipeline connection; and in the traditional welding process, grinding and welding are often carried out separately, which is difficult to synchronize, which not only increases the difficulty and workload of the operation, but also may cause the polished pipeline interface to be contaminated again before welding. For this reason, we provide a petrochemical pipeline interface welding jig. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0021] Example

[0022] like Figure 1-Figure 4 As shown, a petrochemical pipeline butt welding jig proposed in one embodiment of the utility model mainly includes a fixed mounting plate 1, a through hole 2, a mounting frame 3 and a clamping mechanism 4. Among them, the through hole 2 is located at the center of the fixed mounting plate 1, which is convenient for the pipe body 5 to pass through. The mounting frame 3 is firmly mounted on the back of the fixed mounting plate 1 to support and fix the clamping mechanism 4. The clamping mechanism 4 is mounted at the lower end of the mounting frame 3, and the pipe body 5 is fixed in an appropriate position through its clamping action to ensure the accuracy of welding.

[0023] Among them, on the front side of the fixed mounting plate 1, a rotating ring 6 is installed around the periphery of the through hole 2. A sleeve ring 7 is rotatably sleeved on the periphery of the rotating ring 6, and the sleeve ring 7 can rotate freely around the rotating ring 6. A gear ring 8 is fixedly connected to the periphery of the sleeve ring 7, providing an interface for subsequent rotational drive. A welder 9 is installed at the port of the sleeve ring 7 for welding the pipe body 5; on the back side of the fixed mounting plate 1, a driving motor 10 is fixedly installed. A gear plate 11 is connected to the output end of the driving motor 10, and the gear plate 11 is meshed with the gear ring 8. When the driving motor 10 is started, the sleeve ring 7 can be driven to rotate around the rotating ring 6 through the meshing action of the gear plate 11 and the gear ring 8, thereby driving the welder 9 to perform rotational welding.

[0024] Furthermore, in order to realize the grinding operation before welding, a grinding assembly is connected to the port of the sleeve ring 7 in this embodiment. The grinding assembly mainly includes a connecting block 12, a U-shaped frame 13, a sliding sleeve block 17, a connecting rod 19 and a grinding block 20. The connecting block 12 is fixedly connected to the port of the sleeve ring 7 for connecting the U-shaped frame 13. Bar-shaped through grooves 14 are provided on both sides of the U-shaped frame 13, and vertical fixing rods 15 and springs 16 are arranged in the bar-shaped through grooves 14. The sliding sleeve block 17 is slidably sleeved on the periphery of the vertical fixing rod 15, and elastic support is provided by the spring 16. A lap plate 18 is fixedly connected between the two sliding sleeve blocks 17, and a connecting rod 19 is fixedly connected to the upper surface of the lap plate 18. A grinding block 20 is installed at the end of the connecting rod 19 for grinding the pipe body 5.

[0025] Furthermore, in order to realize the rapid replacement of the grinding block 20, a prismatic plug block 22 is fixedly connected to the end of the connecting rod 19, and a prismatic groove 21 matching the prismatic plug block 22 is formed at the end of the grinding block 20. The rapid installation and removal of the grinding block 20 can be realized through the interference fit between the prismatic plug block 22 and the prismatic groove 21.

[0026] The working principle of the utility model is as follows: first, the pipe body 5 is passed through the through hole 2 and fixed with the clamping mechanism 4. Then the driving motor 10 is started, and the sleeve ring 7 is driven to rotate around the rotating ring 6 through the meshing action of the gear plate 11 and the gear ring 8. During the rotation of the sleeve ring 7, the welder 9 is driven to perform rotational welding. At the same time, the grinding block 20 in the grinding assembly at the port of the sleeve ring 7 will also perform synchronous grinding on the pipe body 5. During the grinding process, due to the elastic support of the spring 16, the lap plate 18 and the connecting rod 19 can slide in the U-shaped frame 13 to adapt to pipe bodies 5 of different diameters. When the grinding block 20 needs to be replaced, the connection rod 19 can be quickly replaced by simply pulling it out of the prismatic groove 21.
