Description

Technical Field

[0001] The utility model belongs to the field of offshore oil engineering, and in particular relates to a node plate hoisting assembly tool. Background Art

[0002] During the general assembly and construction phase of offshore engineering project modules, additional reinforcing ribs are required to increase the strength at the nodes, which results in the flange plates at the joints of local composite beams needing to be replaced with thickened and widened plates. This operation is called "lifting the lid" on site. Currently in conventional module projects, the replacement of flange plates of node composite beams requires the use of tools such as fall chains, and finding nearby rigid structural parts (such as main columns or other upper steel sections) to weld temporary lifting points as the suspension force points. A hand winch is hung at one end, and the node plate to be replaced is hoisted at the other end, and personnel are adjusted to assemble them in place.

[0003] During this construction process, due to the involvement of welding temporary lifting points, the subsequent cutting, grinding and repainting of the lifting points were extremely time-consuming and caused certain damage to the surrounding structural parts. In addition, the lifting of a single lifting point was not stable, and the web of the composite beam was located in the center, which was not conducive to the stable positioning of the node plate.

[0004] Therefore, it is urgent to design a node plate hoisting and assembly tooling to solve the node plate hoisting and assembly problems mentioned above. Utility Model Content
