Description

Technical Field

[0001] The utility model belongs to the technical field of offshore platform detection, and in particular relates to an offshore platform detection lifting device. Background Art

[0002] An offshore platform is a truss structure that is higher than the sea surface and has a horizontal platform surface, which is used for production operations or other activities. During the inspection process of the offshore platform, a lifting device is required to realize the lifting and lowering of the platform body. For example, the existing patent with publication number CN114000485A discloses "a lifting device for offshore operation and maintenance and installation platform, belonging to the field of wind power operation and maintenance and installation. The platform includes a platform body and pile legs. Each pile leg is equipped with a lifting device for driving it to move relative to the platform body. A plurality of groups of axially spaced positioning sites are provided on the side walls of the pile legs. Each group of positioning sites includes a plurality of circumferentially uniformly distributed pin holes. The lifting device includes: a static ring beam, a dynamic ring beam, a static pin, a dynamic pin, a static pin push-pull cylinder, a dynamic pin push-pull cylinder, and a lifting cylinder connected between the dynamic ring beam and the static ring beam." It can be seen that the application describes a common offshore platform inspection lifting device, which relies on multiple cylinders to realize the lifting and lowering of the offshore platform during inspection.

[0003] When the existing offshore platform detection and lifting device is actually used, the ring beam and the pile legs are connected by multiple transverse oil cylinders. However, since the positions of the transverse oil cylinders on the existing offshore platform detection and lifting device are fixed, if the transverse plug holes on the pile legs do not correspond to the positions of the transverse oil cylinders on the ring beam during the actual lifting process, the connection between the ring beam and the pile legs cannot be further achieved, and the lifting of the offshore platform cannot be further achieved. Therefore, the existing offshore platform detection and lifting device has poor flexibility in actual use and has certain limitations. For this reason, the present invention needs to improve and optimize the existing offshore platform detection and lifting device. Utility Model Content
