Continuous hydraulic inserted pin lifting device

Abstract

The invention discloses a continuous hydraulic inserted pin lifting device, and belongs to the field of ocean engineering equipment. The device is characterized in that a pile leg axially passes through a pile fixing rack; a first ring beam and a second ring beam are sequentially arranged on the pile leg from top to bottom in a movable fitting manner; a first inserted pin oil cylinder is arranged on the first ring beam; a second inserted pin oil cylinder is arranged on the second ring beam; a first lifting oil cylinder and a second lifting oil cylinder are correspondingly arranged between the first ring beam, the pile fixing rack and the second ring beam. The device further comprises a guide assembly, wherein one end of each of two bearing rib plates of the guide assembly is arranged on the outer wall of the pile leg, and the other end of each of the two bearing rib plates is connected through a connecting rib plate; two side edges of the connecting rib plate are protruded from the bearing rib plates; first guide blocks and second guide blocks are correspondingly arranged on the side surfaces, facing the pile leg, of the first ring beam and the second ring beam; guide grooves are formed in the first guide blocks and the second guide blocks; two side edges of the connecting rib plate are correspondingly slidably inserted into the guide grooves of two first guide blocks and two second guide blocks. According to the device, the guide assembly is arranged and can save the internal space of the pile fixing rack, so that the internal arrangement of the pile fixing rack is reasonably optimized.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a continuous hydraulic bolt lifting device. Background technique [0002] The self-elevating offshore platform is a kind of tooling with lifting function widely used in marine engineering, which realizes the lifting of the platform through the lifting device. At present, the lifting devices of mainstream self-elevating platforms include hydraulic bolt lifting devices and rack and pinion lifting devices. Compared with the latter, the former has higher carrying capacity and relatively lower cost, and the latter has faster lifting speed than the former . [0003] In the prior art, the hydraulic bolt lifting device usually includes a pile-fixing frame for fixed connection with the offshore platform. There is a ring beam inside, and the ring beam is set on the pile leg. There are a plurality of lifting cylinders arranged in the vertical direction between the ring beam and...

AI Technical Summary

Problems solved by technology

[0005] When the offshore platform is raised and lowered along the length of the pile leg, a guide assembly is usually installed to ensure the lifting direction of the offshore platform. The guide assembly is usually arranged on the pile frame, so that the guide assembly occupies part of the space of the pile frame and affects the lifting Layout of the device
