Abstract

The invention discloses a hydraulic plug lifting device, and belongs to the field of marine engineering equipment. The hydraulic plug lifting device comprises a pile fixing frame, pile legs, an upper ring beam, a lower ring beam, plug assemblies and multiple lifting units arranged side by side. Each lifting unit comprises a first lifting rod, a second lifting rod, a horizontal oil cylinder, upper ring beam sliding blocks, lower ring beam sliding blocks and a lifting rod pin shaft. Two upper ring beam guide rails are arranged at the position, corresponding to each lifting unit, of the upper ring beam. The two upper ring beam sliding blocks of each lifting unit are mounted on the corresponding upper ring beam guide rails in a sliding manner correspondingly. Two lower ring beam guide rails are arranged at the position, corresponding to each lifting unit, of the lower ring beam. The two lower ring beam sliding blocks of each lifting unit are mounted on the corresponding lower ring beam guide rails in a sliding manner correspondingly. According to the hydraulic plug lifting device, continuous ascending and descending of the pile fixing frame are achieved, and the work efficiency and speed of the lifting device are increased.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a hydraulic bolt lifting device. Background technique [0002] The jack-up platform is a kind of lifting device widely used in marine engineering, and the hydraulic bolt lifting device is a common lifting mechanism of the jack-up platform. [0003] The common hydraulic bolt lifting device mainly includes a moving ring beam, a fixed ring beam and a lifting cylinder. The moving ring beam and the fixed ring beam are respectively set on the pile legs. Connection, the fixed ring beam is installed on the platform of the self-elevating platform, and the fixed ring beam and the moving ring beam are equipped with bolt assemblies. When the fixed ring beam is set under the moving ring beam, when the platform is lifted, the bolt assembly in the moving ring beam is separated from the pile leg, the bolt assembly in the fixed ring beam is inserted into the pile leg, and the lifting ...
