Description

Technical Field

[0001] The present invention belongs to the technical field of fixing devices, and in particular relates to a detachable fixing device and method for transporting and installing an offshore platform. Background Art

[0002] In fields such as offshore wind power generation, during the transportation and installation of offshore platforms, considering the complex marine transportation conditions, large equipment on offshore platforms needs to be temporarily tied up. The tying requires setting fixed points on the platform structural components. The traditional fixing method is to weld stiffening ribs and tying plates on the structural components.

[0003] At present, the fixing devices used for the transportation and installation of offshore platforms cannot be disassembled. This is mainly because connection methods such as welding can achieve stable connection with the main beam, beam wing and web of structural members to ensure installation stability, and it is necessary to consider the fixation in multiple scenarios such as deck lashing points, platform column deck rooting and lifting points. It is not easy to design a flexible and detachable fixing device that can be applied to multiple scenarios. Although fixing methods such as welding can achieve stable fixation, the fixing device cannot be recycled and reused, the cost is high, and it occupies on-site space, which will affect the normal operation of the platform and other equipment in the later stage. In summary, there is a lack of a detachable offshore platform fixing device with good fixing stability and high flexibility in scene use. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a detachable fixing device and method for offshore platform transportation and installation, wherein the primary and secondary beams are fixed by a reinforcement mechanism, and the two ends of the reinforcement mechanism are detachably connected by a first connecting mechanism and a second connecting mechanism; and, through the first connecting hole, the first screw and the fixing groove on each reinforcement mechanism, the through hole, the first screw and the second connecting hole on the first connecting mechanism, as well as the setting of the slide groove and the slide rail, a plurality of reinforcement mechanisms can be quickly and flexibly connected.
