[0002] At present, a large number of steel pipe scaffoldings are used in the process of engineering construction and municipal maintenance. They are mainly used in the construction of internal and external frames, unloading platforms, and safety protection of edge openings. Most of these scaffolding steel pipes are used in a rental manner throughout the entire construction period. During the entire construction process, the turnover of materials, the erection and dismantling of scaffolding, etc. will cause a considerable number of steel pipes to bend and deform. In order to make the deformed steel pipes usable again, steel pipe straightening machines are used on the construction site to straighten them.
