[0002] The offshore photovoltaic project needs to build 936 steel platforms at sea. The plane projection size of each support platform is 35m×60m. The number of support platform components is 432,442, and the number of purlins is 194,460. The number of components is very large. The 936 steel platforms also need to be placed on 3,744 steel pipe piles, which makes the construction and installation control extremely difficult. It is impossible to construct by using the traditional method of high-altitude bulk installation. The number of machines and labor is incalculable, so the steel platform assembly task needs to be completed on land in advance. At present, the traditional assembly tire frame adopts the suspension method plus cranes and other lifting tools for assembly. During the construction process, when assembling components of different sizes, matching tools are needed to fix them, so a large number of machines are needed to meet the construction. In the process of fixing components, the unstable lifting will cause the qualified rate of component assembly to be low. Therefore, the traditional assembly tire frame wastes manpower and machinery, and cannot guarantee the qualified rate of components.
