A crown-type prefabricated offshore substation hoisting frame and method
By combining the hoisting frame with the structural frame to form a multi-layer three-dimensional truss, the problems of large weight, safety hazards and layout difficulties of the hoisting frame are solved. This enables safe and efficient hoisting of offshore substations and flexible layout of modular equipment, enhancing the structural load-bearing capacity and photovoltaic power generation function.

AI Technical Summary
Existing hoisting frames are heavy, costly, cannot participate in structural stress, pose safety hazards, and lack other functions. Traditional hoisting frames cannot meet the open layout requirements of modular equipment, and controlling the hoisting rope angle is difficult, posing a risk of hoisting accidents.
The hoisting frame is combined with the structural frame to form a multi-layer three-dimensional truss. The hoisting frame structure and the lower beams and columns share the load. The hoisting platform and photovoltaic modules are introduced, which also serve as firewalls and roof supports. Multiple connection methods are used to adapt to different working conditions.
It improves the structural safety and load-bearing capacity of the offshore substation, reduces the amount of steel used in the lower platform structure, simplifies the structural layout, enhances hoisting safety and the flexibility of modular equipment layout, and provides convenience for photovoltaic power generation and maintenance.
