Description

Technical Field

[0001] The utility model relates to the field of scaffolding, in particular to a tower-type scaffolding. Background Art

[0002] At present, small transport vessels carry out aerial operations basically by carrying out manual hook removal operations and photovoltaic platform panel repair operations during the offshore lifting process of photovoltaic platforms using articulated boom lift aerial work vehicles. However, in offshore photovoltaic platform projects, the hook removal and panel repair operations of a single platform need to be completed in a timely manner each time. At the same time, the maritime transportation time is very long, which causes a large amount of waste of construction machinery resources and greatly consumes financial cost resources. Carrying out aerial operations by transport vessels with vertical pole scaffolding is a method to solve the above-mentioned resource waste. However, the traditional vertical pole scaffolding construction method has the disadvantages of low construction working surface, difficulty in adjusting the working surface height, and inability to ensure the stability of the working surface during offshore construction.

[0014] When the scaffold is erected, the adjusting screw is rotated to make the support plate higher than the ship deck (while tightening the limit bolt to prevent the adjusting sleeve from rotating), then the scaffold is pushed to the designated position, the limit bolt is loosened, the triangular guard is rotated to a suitable position, and then the limit bolt is tightened to limit the triangular guard (so that there is a certain angle between the triangular guard and the base frame), then the adjusting screw is rotated to make the support plate rest on the ship deck, the entire scaffold is limited, and the erection is completed;

[0015] Construction workers can climb up through the first ladder, the second ladder and the third ladder.

[0016] The beneficial effects of the utility model are: different from the traditional vertical pole scaffolding, the scaffolding construction process is simplified, the stability of the scaffolding is ensured by utilizing the stable characteristics of the tower-shaped steel structure, and at the same time, all-round rotation and movement can be achieved through the universal wheels to adapt to various working environments on the ship.
