Description

Technical Field

[0001] The present invention relates to the technical field of tower welding, and specifically provides a welding and fixing tooling for tower steel structures. Background Art

[0002] Towers are mainly composed of steel structures spliced together and fixed by welding and bolt connection. The members are mainly composed of single equal-angle steel or combined angle steel. The steel pipe tower structure has relative technical and economic advantages. The steel structure tower has a small wind pressure, a large cross-sectional bending stiffness, a simple structure, and clear force transmission, and can give full play to the bearing performance of materials. On the one hand, it can reduce the weight of the tower and the foundation acting force, and on the other hand, it is beneficial to enhance the ability to resist natural disasters under extreme conditions. The cross-section of the steel pipe member is centrally symmetric, and the material is evenly distributed around the perimeter, with a large cross-sectional bending stiffness. In terms of structural connection, the main members of the steel structure tower are connected by flange intersection or welded by a welding device. The main members of the tower adopt internal and external connections, and other members are mainly connected by connecting plates and bolts.

[0003] The patent with the publication number CN117798587A discloses a welding and fixing tooling for tower steel structures, belonging to the technical field of tower welding. The welding and fixing tooling for tower steel structures includes a tooling base. The center of the top of the tooling base is provided with an auxiliary support mechanism. One side of the top of the tooling base is provided with an adjusting base mechanism. One end of the top of the tooling base far from the adjusting base mechanism is fixedly connected with a fixed base assembly. Rotating adjustment mechanisms are installed on the tops of the adjusting base mechanism and the fixed base assembly. Two support arm mechanisms are rotatably connected to each of the two rotating adjustment mechanisms. The front end faces of the tops of the adjusting base mechanism and the fixed base assembly are fixedly connected with adjusting driving mechanisms. The present invention designs two groups of support arm mechanisms and a steel pipe fixing mechanism that can move inside them, improving the applicable range of the overall tooling and making it more accurate according to the indication of the scale. The device has a simple structure and low manufacturing cost.

[0004] This application improves the applicable range of the overall tooling by designing two groups of support arm mechanisms and a steel pipe fixing mechanism that can move inside them, and makes it more accurate according to the indication of the scale. However, this device cannot fix a triangular-shaped tower during tower welding, and at the same time, it cannot change the size of the openings at both ends of the tower during welding.
