Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, and particularly relates to a pipeline welding fixing tool. Background Technique

[0002] The pipeline welding fixing tool is an important device used to ensure that the position and direction of the pipeline do not shift during the pipeline installation and welding processes. These tools can firmly clamp the pipeline and fix it in the required position, thereby ensuring the welding quality, improving work efficiency, and reducing the manual labor intensity. Specifically, the pipeline welding fixing tools include various types, such as strong-jaws pliers, electrofusion fixing jigs, three-way electrofusion fixing jigs, etc. They each have different characteristics and uses, but all aim to ensure the stability and accuracy of the pipeline during the welding process. For example, the strong-jaws pliers can clamp the pipeline and prevent it from moving, thereby ensuring the flatness of the welding surface and the quality of the weld seam; while the electrofusion fixing jig is used to fix the pipe during electrofusion welding to ensure that the pipe does not displace during the fusion and cooling processes, ensuring good airtightness. It can ensure the stability of the pipeline, improve the welding quality, and reduce the labor intensity.

[0003] Currently, when welding two half-pipelines, it is necessary to fix the two half-pipelines before welding. However, before the two half-pipelines are connected, due to the influence of shaking and vibration, there will be small deviations at their connection points, resulting in small deviations after the two half-pipelines are welded, affecting the service quality of the welded pipeline. Therefore, a pipeline welding fixing tool is proposed. Content of the Utility Model

The first positioning frame 7 is in an inverted V shape. The second positioning frame 9 is in a V shape. The top of the second positioning frame 9 is movably connected to a half pipe. The bottom of the first positioning frame 7 is welded with a half pipe. Two reinforcing rods 10 are fixedly installed between the second positioning frame 9 and the frame body 1.

[0025] A second threaded rod 11 is threadedly connected inside the frame body 1. The right side of the second threaded rod 11 is rotatably connected to a second connecting seat 12. An adjusting plate 13 is fixedly installed on the right outer wall of the second connecting seat 12. A limiting seat 14 is fixedly installed on the right outer wall of the adjusting plate 13. The adjusting plate 13 is circular. The limiting seat 14 is in a semi-circular ring shape. The inner diameter of the limiting seat 14 is the same as the radius of the half pipe. A limiting rod 15 is fixedly installed on the left outer wall of the adjusting plate 13. A threaded hole is opened inside the frame body 1. An adjusting hole is opened inside the frame body 1. The second threaded rod 11 is threadedly connected inside the threaded hole and is of a suitable size. The limiting rod 15 is slidably connected inside the adjusting hole and is of a suitable size.

[0026] In this embodiment, the limiting seat 14 will limit and fix the bottom half pipe, so that the half pipe cannot move back and forth when it is vibrated and shaken.

[0027] In this embodiment, when the bottom half pipe is connected to the top half pipe, the staff needs to push the bottom half pipe to the left so that the bottom half pipe is closely attached to the right outer wall of the adjusting plate 13.

[0030] The working principle of the above embodiment is as follows:

[0031] First, weld the upper half of the pipe to the outer wall of the bottom of the first positioning bracket 7. At this time, place the lower half of the pipe on the outer wall of the top of the second positioning bracket 9. Then rotate the second threaded rod 11 to drive the adjusting plate 13 to move to the right. At this time, the adjusting plate 13 is restricted by the limiting rod 15 and cannot rotate. At this time, the limiting seat 14 will move to the right and connect with the lower half of the pipe. Then rotate the first threaded rod 4 to drive the first positioning bracket 7 to move downward. At this time, the first positioning bracket 7 is restricted by the sliding rod 8 and cannot rotate. When the upper half of the pipe is close to the lower half of the pipe, push the lower half of the pipe in the direction close to the adjusting plate 13 to make it closely attached and fixed. Then continue to rotate the first threaded rod 4 to make the upper half of the pipe and the lower half of the pipe closely attached to each other. At this time, they can be welded and fixed by a welding tool.
