Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a saddle-shaped pipeline welding assembly. Background Art

[0002] When installing the pipeline, a through hole is set on the main pipe, and the branch pipe is set in the through hole. The branch pipe intersects with the main pipe to form a saddle-shaped notch, which needs to be welded into a saddle-shaped weld by a welding machine. In the prior art, one person usually holds the main pipe and the branch pipe, and another person performs welding. This method not only has low welding efficiency, but also requires the cooperation of multiple people to complete, thereby increasing construction costs.

[0003] The utility model patent with application number CN202121174971.X in the prior art discloses a welding device for pipeline saddle welds, including a frame, a first clamping member and at least one second clamping member are provided on one side of the frame, and a welding assembly is fixedly connected to one side of the frame through a fixing rod. The welding assembly includes a circular ring, and an annular groove is provided on the inner ring surface of the circular ring. A slider is slidably connected in the annular groove, and one side of the slider is fixedly connected to a base block. A walking device for controlling the slider to slide along the annular groove is provided on one side of the base block. A sliding hole is provided on one side of the base block, and a crossbeam is slidably connected in the sliding hole. A suspension rod is provided on the crossbeam, and a welding gun is fixedly connected to the lower end of the suspension rod. Only one person is required to complete the welding operation, which can improve the welding efficiency. The position of the variable welding gun is suitable for main pipes and branch pipes of different diameters, and has strong applicability; but in actual use, the existing technology has the following disadvantages: 1. The installation of the frame and the alignment of the pipeline welds also require a lot of man-hours; 2. The saddle-shaped welding of the prior art is to directly cut a saddle-shaped notch in the branch pipe and align it with the weld for welding. After welding, a saddle-shaped edge is formed at the connection between the main pipe and the branch pipe, which will cause impact and kicking when used in a high-pressure and high-speed fluid environment, affecting the service life of the pipe; 3. The branch pipe is generally processed on-site. When the branch pipe is long, the processing difficulty is high and it also requires a lot of man-hours; therefore, there is room for improvement.
