[0001] The utility model relates to the technical field of auxiliary support structures, and specifically relates to an auxiliary support mechanism for welding angle steel towers for large-scale safe power transmission. Background Technique

[0002] Electric power angle steel towers play a key role in supporting and protecting power transmission lines. Electric power angle steel towers have excellent load-bearing capacity, structural stability and corrosion resistance. They can withstand external loads such as high-intensity wind pressure, ice load, and earthquake, thus ensuring the stable operation of power transmission lines.

[0003] In the prior art, during the welding process of angle steel towers, a large number of angle steels need to be welded and connected. Since the angle steels are large and heavy, it is often necessary to build a support frame to support the angle steels.

[0004] However, general support frames are fixedly installed. When support at different heights is required, it is often necessary to build support frames of different heights for auxiliary support, which is not convenient for adjustment and reduces the stability. At the same time, general support frames can only support a single angle steel at a time, thus reducing the use efficiency. Therefore, the utility model proposes an auxiliary support mechanism for welding angle steel towers for large-scale safe power transmission to solve the above problems. Content of the Utility Model
