The invention discloses a plug pin lifting mechanism for a self-elevating platform and belongs to the field of marine engineering equipment. The plug pin lifting mechanism comprises a pile fixing frame, an upper ring beam, a lower ring beam, at least two upper lifting oil cylinders and at least two lower lifting oil cylinders, wherein the pile fixing frame is fixedly mounted on a platform main body of the self-elevating platform; a pile leg of the self-elevating platform penetrates the pile fixing frame and is movably inserted in the self-elevating platform; the upper ring beam and the lower ring beam movably sleeve the pile leg respectively; a plug pin component for limiting the axial movement of the upper ring beam along the pile leg is arranged on the upper ring beam; a plug pin component for limiting the axial movement of the lower ring beam along the pile leg is arranged on the lower ring beam; one end of each upper lifting oil cylinder is fixedly mounted at the top of the pile fixing frame; the other ends of the upper lifting oil cylinders are fixedly mounted on the upper ring beam; one end of each lower lifting oil cylinder is fixedly mounted at the top of the pile fixing frame; and the other ends of the lower lifting oil cylinders are fixedly mounted on the lower ring beam. The plug pin lifting mechanism improves the working efficiency of the self-elevating platform.
Description
technical field [0001] The invention belongs to the field of marine engineering equipment, and in particular relates to a bolt lifting mechanism for a self-elevating platform. Background technique [0002] Jack-up platform is a kind of lifting device widely used in marine engineering. Common jack-up platforms are mainly divided into rack-and-pinion lifting platform and pin-type lifting platform according to different lifting mechanisms. The mechanism is a latch lifting mechanism. [0003] The common bolt lifting mechanism mainly includes the upper ring beam, the lower ring beam and the lifting cylinder. The upper ring beam and the lower ring beam are respectively set on the pile legs. Beam connection, the lower ring beam is installed on the main body of the platform, the lower ring beam and the upper ring beam are equipped with latch assemblies, when the platform is lifted, the latch assemblies in the upper ring beam are separated from the pile legs, and the latch assemblie...
