Abstract

The invention discloses a hydraulic lifting device, and belongs to the field of ocean engineering. The device comprises a jacking frame sleeved on a pile leg, a fixed ring beam, a lifting cylinder, a moving ring beam, a plurality of first inserted pin modules arranged on the fixed ring beam, and a plurality of second inserted pin modules arranged on the moving ring beam, wherein both ends of the lifting cylinder are respectively connected with the fixed ring beam and the moving ring beam; one end of the jacking frame is connected with the fixed ring beam, and the other end of the jacking frame is provided with a connecting structure for detachably connecting with a ship body. The jacking frame and the ship body are detachably connected, so that the hydraulic lifting device is simple in connection and convenient to detach; and the lifting device is compact in inner structure, small in size of integral structure and convenient to transport integrally; the hydraulic lifting device is directly assembled with the ship body after reaching the destination; and all structures inside are not required to be assembled again, so that the work load is reduced.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a hydraulic lifting device. Background technique [0002] With the deepening of ocean exploration and development, more and more people pay more and more attention to the research on jack-up ocean platforms. [0003] The self-elevating offshore platform mainly includes legs, leg support structure and sinking pad, hull (platform), and lifting device. The lifting device is connected to the hull, and the lifting device can drive the hull to rise or fall along the legs. Wherein, the lifting device mainly includes a pile fixing frame and a lifting structure. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] When transferring the lifting device, since the existing pile frame is welded with the hull, it is not easy to disassemble, so the lifting structure is usually disassembled for...
