Abstract

The invention discloses a hydraulic bolt type lifting device and belongs to the field of ocean platform equipment. The hydraulic bolt type lifting device comprises a pile leg, an upper ring beam, a lower ring beam, lifting oil cylinders and a plurality of bolt assemblies. The hydraulic bolt type lifting device also comprises an upper lifting oil cylinder mounting base and a lower lifting oil cylinder mounting base. The upper lifting oil cylinder mounting base comprises supporting bases and connecting bodies, wherein the quantity of the supporting bases is equal to that of the upper lifting oilcylinders; each of the supporting bases comprises an upper lifting oil cylinder mounting ear plate and two upper lifting oil cylinder mounting ear plate brackets; each of the connecting bodies comprises a lateral connecting plate, a plurality of second rib plates and a plurality of middle connecting plates. The hydraulic bolt type lifting device can bear a relatively large load, and is unlikely to deform, so that the stability of the hydraulic bolt type lifting device is improved.

Description

technical field [0001] The invention relates to the field of offshore platform equipment, in particular to an oil cylinder installation structure and a hydraulic bolt type lifting device. Background technique [0002] The jack-up offshore platform is widely used in marine engineering. The jack-up offshore platform includes a platform body and a lifting system. The commonly used lifting system is a hydraulic bolt-type lifting system. [0003] The hydraulic bolt-type lifting system includes: pile legs, pile fixing frame, upper ring beam, lower ring beam, lifting cylinder and multiple bolt components. The upper ring beam, lower ring beam and pile fixing frame are all arranged around the pile legs, and multiple bolts The components are respectively installed on the upper ring beam and the lower ring beam, and the two ends of the lifting cylinder are respectively installed on the upper ring beam and the lower ring beam. The top of the frame is a box structure and is connected to...
