[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.

[0025] Referring to Figures 1-4 , a pipeline welding rotation adjustment device includes a base 1. Two fixing blocks 9 are fixedly installed on the surface of the base 1. The two fixing blocks 9 are symmetrically arranged. A triangular chuck 13 for fixing the pipeline is rotatably connected to the surface of the fixing block 9. A driving mechanism for driving the triangular chuck 13 to rotate is arranged on the surface of the fixing block 9. A pressing mechanism for pressing the pipeline is arranged on the surface of the base 1. Support rods 3 are arranged at positions near both ends on both sides of the base 1. During use, first, the two pipelines to be welded are respectively placed in the triangular chucks 13 on the two fixing blocks 9, and the weld position is located between the two fixing blocks 9. Then, the two pipelines are fixed by using the triangular chuck 13, so as to achieve the purpose of making the two pipelines coaxial. Then, the two pipelines are pressed towards the middle by using the pressing mechanism, so that the gap between the two pipelines can be reduced. Finally, a welding gun is used to weld the gap between the two pipelines. During the welding process, the two triangular chucks 13 can be directly rotated by using the driving mechanism, so that the circumferential weld can be located above, which is convenient for welding operation and does not require manual rotation of the pipeline.

[0026] Furthermore, two moving wheels 2 are rotatably connected to the end of the base 1. A handle 5 is fixedly installed at one end of the base 1 away from the moving wheels 2. By setting the moving wheels 2 and the handle 5, it is convenient to directly move the entire base 1.

[0027] Furthermore, receiving grooves 4 are opened at positions near both ends on both sides of the base 1. One end of the support rod 3 is rotatably arranged inside the receiving groove 4 so that the support rod 3 can be received inside the receiving groove 4. By setting the support rod 3, the stability of the base 1 can be enhanced, and the support rod 3 can be received inside the receiving groove 4 when not in use, without occupying a large space.

[0028] Furthermore, a connecting ring 14 is fixedly installed on the side wall of the triangular chuck 13. A receiving groove 17 is opened on the surface of the fixing block 9. The triangular chuck 13 is arranged inside the receiving groove 17. The connecting ring 14 is rotatably connected to the inner wall of the receiving groove 17. Circular holes for the pipeline to pass through are opened on the surfaces of the fixing block 9 and the triangular chuck 13.

[0029] Further, the driving mechanism includes a transmission shaft 10 which is rotatably connected inside the fixed block 9. A worm 11 is fixedly installed on the surface of the transmission shaft 10 at a position inside the fixed block 9. A worm gear 15 is fixedly installed on the surface of the connecting ring 14. The worm gear 15 meshes with the worm 11. An embedding groove 16 is formed on the surface of the fixed block 9, and the worm gear 15 is arranged inside the embedding groove 16. Both ends of the two transmission shafts 10 penetrate through the fixed block 9. Belt pulleys 12 are fixedly installed on the surfaces of the transmission shafts 10 at positions outside the fixed block 9. The two belt pulleys 12 are connected by a belt in a transmission manner. Rotating handles are fixedly installed on the surfaces of the two transmission shafts 10 away from the belt pulleys 12. During the use of the driving mechanism, directly manually rotate the rotating handle, the rotating handle drives the transmission shaft 10 to rotate, the transmission shaft 10 drives the worm 11 to rotate, the worm 11 drives the worm gear 15 to rotate, and the worm gear 15 drives the triangular chuck 13 to rotate, so as to achieve the purpose of rotating the entire pipeline by using the triangular chuck 13. Moreover, the two transmission shafts 10 are connected by the belt pulleys 12 and the belt, so as to realize the synchronous rotation of the two triangular chucks 13, and further make the two pipelines rotate synchronously, improving the welding convenience.

[0030] Further, long grooves 8 are formed on the surface of the base 1. Two moving rods 7 are slidably connected at the positions of the long grooves 8. A screw rod 6 is rotatably connected inside the long groove 8. The screw rod 6 is provided with two sections of opposite threads with its midpoint as the demarcation line. The two moving rods 7 are respectively threadedly connected to the two ends of the screw rod 6. One end of the screw rod 6 threadedly penetrates through the base 1 and is fixedly installed with a knob. By setting the moving rods 7, the purpose of tightly pressing the pipeline from both ends can be achieved. In the specific operation, directly manually rotate the knob, the knob drives the screw rod 6 to rotate, and the screw rod 6 uses the two sections of threads on its surface to respectively drive the two moving rods 7 to move in opposite directions in the long groove 8, and then the moving rods 7 contact the end of the pipeline.

[0031] In summary, during use, first place the two pipes to be welded in the triangular chucks 13 on the two fixing blocks 9 respectively, and position the weld seam between the two fixing blocks 9. Then use the triangular chucks 13 to fix the two pipes, thereby achieving the purpose of making the two pipes coaxial. Then use the tightening mechanism to tighten the two pipes towards the middle, so that the gap between the two pipes can be reduced. Finally, use a welding torch to weld the gap between the two pipes. During the welding process, the driving mechanism can be directly used to rotate the two triangular chucks 13, so that the circumferential weld seam can be located above, facilitating the welding operation without manually rotating the pipes. By setting the moving wheels 2 and the handle 5, it is convenient to directly move the entire base 1. By setting the support rod 3, the stability of the base 1 can be enhanced, and the support rod 3 can be stored inside the storage groove 4 when not in use, without occupying too much space. During the use of the driving mechanism, directly manually rotate the rotating handle, the rotating handle drives the transmission shaft 10 to rotate, the transmission shaft 10 drives the worm 11 to rotate, the worm 11 drives the worm gear 15 to rotate, and the worm gear 15 drives the triangular chuck 13 to rotate, thereby using the triangular chuck 13 to achieve the purpose of rotating the entire pipe. Moreover, the two transmission shafts 10 are connected by a belt pulley 12 and a belt, so as to realize the synchronous rotation of the two triangular chucks 13, and then make the two pipes rotate synchronously, improving the welding convenience. By setting the moving rod 7, the purpose of tightening the pipes from both ends can be achieved. In specific operations, directly manually rotate the knob, the knob drives the screw rod 6 to rotate, and the screw rod 6 uses the two sections of threads on its surface to drive the two moving rods 7 to move in opposite directions in the long groove 8, and then the moving rod 7 contacts the pipe end.
