Abstract

The invention discloses a hydraulic bolt lifting device, and belongs to the field of ocean engineering equipment. A pile leg of the device movably penetrates a pile fixing frame, a plurality of rows of bolt holes are formed in the pile leg, a ring beam comprises a plurality of sliding yokes, and a bolt oil cylinder capable of being inserted into the corresponding bolt hole is arranged at the middle portion of each sliding yoke; the two ends of each lifting oil cylinder are connected with the corresponding sliding yoke and the pile fixing frame corresponding, and two lifting oil cylinders are symmetrically installed at the positions, on the two sides of the corresponding bolt oil cylinder, of each sliding yoke; and the plane where the center axis of the two lifting oil cylinders on each sliding yoke is located is the first plane, a bolt oil cylinder cross section where points, in contact with the corresponding bolt holes, of the bolt oil cylinder on each sliding yoke are located is the second plane, and the second plane and the first plane are located on one plane. By means of the hydraulic bolt lifting device, under the condition that the weights of the sliding yokes are the same, the sliding yoke can bear larger loads.

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 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. [0003] At present, the lifting devices of the mainstream self-elevating offshore platforms include hydraulic bolt lifting devices and rack and pinion lifting devices. quick. Although the structure types of the hydraulic bolt lifting devices are different, the lifting principle is similar, mainly through the mutual cooperation of the vertical lifting cylinder and the horizontal bolt cylinder to realize the relative lifting of the legs and the platform. [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] In the hydraulic b...
