The core concept of the assembly mobile welding operation platform is high efficiency,flexibility, and safety. The main components of the platform are connected by standardized bolts, whichcan simplify the installation and disassembly process so that the operation platform can easily realizerepeated disassembly and rapid transfer construction, which greatly improves the construction efficiency.Tower cranes were used for integral lifting operations. The operation platform can be flexibly scheduled invarious areas of the construction site, which saves both the time and the labor cost required for theerection and demolition of the traditional frame. MIDAS finite element software was used to analyze theforce of the assembled movable operating platform. The calculation results indicate that the overall forceof the operating platform is uniform and the deformation is stable, which can ensure the constructionsafety and installation accuracy in the actual use process. Finally, the design schemes of differentoperating platforms are comprehensively compared and selected. And the erection method that best meetsthe current construction requirements is further screened out to ensure that the practicability and economyof the platform achieve the optimal balance.
