Description

Technical Field

[0001] The utility model relates to the technical field of modular construction of marine platforms, in particular to a modular flare arm auxiliary equipment for marine platforms. Background Art

[0002] For the size of a general flare boom, the overall prefabrication takes a long time and occupies a lot of space. In addition, the installation of the prefabricated flare boom will have an adverse effect on the equipment on the ship module and the hoisting of the deck plate. In order to avoid the above problems, the flare boom usually needs to be prefabricated in sections, and a section plan is formulated in advance. In the process of prefabricating the flare boom in sections, most of the rods in the flare boom are round tube rods, and their nodes are complex nodes, with a large number of T, K, and Y-type nodes. Most of the ports where each steel pipe intersects with the main pipe are saddle mouths. When the nodes of the flare boom in the prefabrication of sections are mainly connected in the form of saddle mouths, the crane usually cannot accurately control the position of the steel pipe during assembly, resulting in a difficult assembly process. At present, when the steel pipe of this type of segmented flare boom is closed at a low position with the saddle mouth, the steel pipe is usually lifted by a crane, and the steel pipe is aligned with the saddle mouth by manually pulling the slip rope. This method results in a large labor demand, high construction risk, and slow hoisting speed. Therefore, how to provide an auxiliary device to improve the efficiency of closing the flare arm steel pipe with the saddle mouth is a difficult problem in the segmented prefabrication of the flare arm of an offshore engineering project.
