Description

Technical Field

[0001] This utility model belongs to the field of pipe fitting processing and manufacturing technology, and in particular relates to an auxiliary equipment for unbalanced pipe welding. Background Technology

[0002] Unbalanced pipe welding involves welding the heavier end, completely welding the bend to the straight pipe section, and welding other auxiliary equipment such as pipe fittings, thermocouples, and thermometers during the piping process. Due to the weight difference, the lighter end often tilts up, making it impossible to weld using a welding machine.

[0003] In addition, the unbalanced pipe involved in this utility model is a large pipe fitting, and the roller base 3 is very heavy. If the two roller bases 3 are repeatedly moved and adjusted to find a precise balance point, it is time-consuming and laborious.

[0004] Secondly, the roller base 3 is generally used in a fixed position (i.e., the roller base 3 is fixed to the ground or support by fasteners), and it is difficult to ensure absolute levelness and stability after it is moved. Instability of the roller base 3 can cause slight displacement of the unbalanced pipe during welding, which directly affects the straightness of the weld, the interface gap and other critical dimensions, and in severe cases, can cause welding defects.

[0005] More importantly, if the lighter end of the unbalanced tube is not restricted, the center of gravity of the unbalanced tube will change during rotation, causing the unbalanced tube to lose balance again.

[0006] Furthermore, some existing methods involve welding a connecting pipe of equal weight to the lighter end of the unbalanced pipe, which wastes welding materials. Others have applied a counterweight of several tons above the lighter end of the unbalanced pipe, but this is difficult to manufacture and implement, and also poses a safety hazard.

[0007] Therefore, it is necessary to design an auxiliary device for welding unbalanced pipes, which can apply pressure to the lighter end of the unbalanced pipe to prevent it from tilting up, without hindering the rotation of the unbalanced pipe. Utility Model Content

[0019] As another preferred embodiment, the nut 26 of this invention is welded to the platform 27.

[0020] As another preferred embodiment, the present invention provides two pressing rollers 273 arranged laterally.

[0021] As another preferred embodiment, the pressing roller 273 of this utility model is connected to the lower end of the platform 27 via an extension column 271. The two extension columns 271 are connected in the middle by a connecting rod 272. The lower end of the extension column 271 is provided with a downwardly extending roller mounting plate.
