Description

Technical Field

[0001] The invention relates to the technical field of branch pipe assembly support frames, in particular to a support frame for assembling branch pipes of a steel pipe tower plug plate. Background Art

[0002] With the development of social economy, the demand for electricity in industrial production and life is gradually increasing. UHV power transmission has become the first choice for power transmission due to its long transmission distance, large capacity and low transmission loss. In the installation of UHV power transmission and transformation, most of them use steel pipe towers as load towers. Steel pipe towers are equipment for supporting overhead lines used for high-voltage overhead line transmission. Due to the advantages of small footprint and high strength, the equipment itself is widely used in the installation of urban and rural internal and external lines. Steel pipe tower branches are important components of steel pipe towers. In the process of processing steel pipe tower branches, a large number of plugs need to be welded on the outside of the steel pipe tower branches. Therefore, steel pipe tower branches need to be effectively supported and fixed with support frames.

[0003] However, some existing support frames for assembling branch pipes of steel pipe tower plug plates are not convenient for fixing branch pipes of different thicknesses during use. Traditional fixing brackets are only convenient for fixing branch pipes of the same specification, which reduces the practicability of the support frame. At the same time, the existing support frames for assembling branch pipes of steel pipe tower plug plates are not convenient for adjusting the height during use. Workers need to weld a large number of plug plates on the outside of the branch pipes of the steel pipe tower. When the height of the branch pipe is too low, workers need to bend over for a long time to operate, which wastes a lot of physical strength, thereby reducing the workers' work efficiency. For this reason, we propose a support frame for assembling branch pipes of steel pipe tower plug plates to solve the above problems. Summary of the invention
