Description

Technical Field

[0001] The utility model relates to the technical field of round pipe welding, in particular to a round pipe welding and assembling device. Background Art

[0002] During the processing of round tubes, they will be welded with multiple branch tubes to make the application range of round tubes wider. The welding of round tubes is also an important process. The correct welding method can not only ensure the quality and stability of the round tube, but also ensure the firmness and sealing of the welding parts.

[0003] In some environments with strict construction requirements, since the circular tube is a hollow concentric circle, when it is welded with the branch pipe, it is required to realize an asymmetric tree branch steel structure with the center lines of the complex node and multiple pipe intersections in the same horizontal plane. At this time, the positioning points for welding the branch pipe and the main pipe are very clear. However, when the existing circular tube welding assembly device is in use, the branch pipe cannot be effectively positioned when it is welded to the main pipe, so that it cannot be in a stable state before welding, resulting in misalignment during welding, and ultimately causing the center lines of the branch pipes and the main pipe to be not in the same horizontal plane, affecting the use of the circular pipe after welding, resulting in waste of construction resources and reduced work efficiency.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can provide limited support for the two ends of the main pipe by arranging two side support frames, so that the main pipe is fixed and cannot move. By arranging the movable support frame, the branch pipe can be connected with the flange according to the welding angle, so as to drive the branch pipe to move and weld with the main pipe. Before welding, the magnetic plate is started to fix the movable support frame and the welding table, and then the branch pipe is fixed. At this time, the branch pipe and the main pipe are both in a fixed state, and the welding work is started. The axial center height of the movable support frame and the side support frame is the same, so the welding center line of the branch pipe and the main pipe is in the same horizontal plane, which solves the problem that when the existing round pipe welding assembly device is in use, the branch pipe cannot be effectively positioned when being welded to the main pipe, so that it cannot be in a stable state before welding, resulting in misalignment during welding, and finally causing the center lines of each branch pipe and the main pipe to be not in the same horizontal plane, affecting the use of the round pipe after welding, causing waste of construction resources and reduced work efficiency.
