Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to galvanized round pipe welding equipment. Background Art

[0002] Galvanized round pipe is a pipe with a circular cross-section and a layer of zinc on its surface. This pipe is mainly made of low-carbon steel or alloy steel. Its circular structure enables it to evenly disperse force when under pressure. It is widely used in many fields such as construction and machinery manufacturing. When using galvanized round pipes, it is often necessary to weld two galvanized round pipes together.

[0003] At present, when the ends of galvanized steel pipes are positioned and fixed for welding, the equipment or fixtures are usually designed according to the vertical docking method of the steel pipe ends. However, when facing the working condition of welding two steel pipes at a certain tilt angle, the conventional positioning and clamping structure cannot adapt well to this non-vertical docking situation. At this time, manual support and pressing are generally used for operation, but this method has many disadvantages. On the one hand, workers are very likely to be burned by welding sparks during the welding process and face threats to their personal safety; on the other hand, since manual support is difficult to always maintain absolute stability, it is very easy to cause the steel pipe to shift in position during the welding process, resulting in the steel pipe being welded crookedly, which will undoubtedly have an adverse effect on the welding quality, and may further affect the overall performance and reliability of subsequent related projects or products. Therefore, how to improve this welding and fixing method to solve the problems faced when welding steel pipes at tilted angles has become one of the key issues that need to be solved urgently. To this end, we propose a galvanized round pipe welding equipment. Summary of the Invention

[0050] See Figure 6-Figure 8 As shown, the rotating assembly 5 includes two outer semicircular plates 51 and two inner semicircular plates 52. The two outer semicircular plates 51 can be combined into an outer circular plate, and the two inner semicircular plates 52 can be combined into an inner circular plate. The two inner semicircular plates 52 are rotatably arranged in the two outer semicircular plates 51, and the side walls of the two inner semicircular plates 52 are fixed with semicircular gear rings 53. The outer wall of the outer semicircular plate 51 is installed with a second motor 54. The output end of the second motor 54 is installed with a gear 55. The gear 55 is meshed and connected to the gear ring 53. An arc-shaped strip 57 is fixed to the inner wall of the circular plate 51, and an arc-shaped groove 56 is opened on the outer wall of the inner semicircular plate 52 to match the arc-shaped strip 57, so that the two outer semicircular plates 51 are combined into an outer circular plate.
