[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

The patent uses a moving mechanism, a third positioning ring and a second positioning ring to design, and by rotating the screw rod, the moving platform is moved to adjust the position of the moving platform to achieve the linear positioning of the first positioning ring, the second positioning ring, the third positioning ring and the fourth positioning ring. The design of the bolt, the first sliding assembly, the second sliding assembly, the first positioning ring, the second positioning ring, the third positioning ring and the fourth positioning ring can clamp the round tubes in the multiple positioning rings by rotating the bolts, so that the round tubes will not shake during welding. The positions of the first positioning ring and the fourth positioning ring can be moved by the first sliding assembly and the second sliding assembly, so that the round tubes can obtain better support.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the steel pipe is clamped inside the second positioning ring and the third positioning ring by bolts, so that the positions of the two steel pipes are fixed, and the steel pipe needs to be welded circumferentially around the welding point during welding. At this time, after welding one place, the staff may need to loosen the bolts and rotate the steel pipe to adjust the position, and then the position of the steel pipe may deviate after the second clamping, which may affect the use effect of the welding adjustment device.

[0006] In view of this, we propose a steel structure butt welding adjustment device. Utility Model Content
