Description

Technical Field

[0001] The utility model relates to a building steel structure welding device, belonging to the technical field of steel structure welding. Background Art

[0002] Steel structure is a structure made of steel materials and 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 sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. 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.

[0003] For example, CN219131347U discloses a welding device for building steel structures, which can perform circular welding on steel structures without manually turning over steel pipes for welding; it is also easy to install and disassemble, which is conducive to popularization and use. However, since the steel structure is placed vertically and connected, the installation height of the steel structure is relatively high, and it is necessary to use equipment such as cranes when loading and unloading, which is inconvenient to operate. In addition, the placement frame and protective pad are only convenient for clamping and fixing rectangular steel structures, and it is more difficult to clamp and fix cylindrical steel structures, making the practicality of the welding device insufficient.

[0009] Furthermore, snap rings are provided on both sides of the outer portion of the gear, and the snap rings are embedded in the annular bracket, and the snap rings are rotatably connected inside the annular bracket.

[0010] Furthermore, a plurality of balls are embedded and connected inside the clamping ring. Two groups of balls are provided on the clamping ring and are symmetrically arranged on both sides of the clamping ring. The balls are in contact with the inner wall of the annular bracket.

[0011] Furthermore, the clamp seat is rectangular, the positioning bolt is rotatably connected inside the clamp plate, and an arc groove is opened inside the clamp plate.

[0012] Furthermore, an L-shaped bracket is provided on one side above the bottom plate, an electric telescopic rod is provided on one side above the L-shaped bracket, and a welding head is connected to the bottom of the electric telescopic rod.

[0013] The beneficial effects of the utility model are:
