The invention discloses a truss pile leg hydraulic bolt lifting platform, and belongs to the field of self-elevating ocean platforms. A truss pile leg comprises a truss pile leg body, a pile fixing frame and a lifting unit arranged in the pile fixing frame. The lifting unit comprises an upper-layer movable ring beam, an upper-layer lifting oil cylinder, a lower-layer movable ring beam, a lower-layer lifting oil cylinder and a bolt assembly, the upper-layer movable ring beam slidably sleeves the truss pile leg body, and the two ends of the upper-layer lifting oil cylinder are connected to the top of the pile fixing frame and the upper-layer movable ring beam respectively. The lower movable ring beam slidably sleeves the truss pile leg body, the two ends of the lower-layer lifting oil cylinder are connected to the bottom of the pile fixing frame and the lower-layer movable ring beam respectively, and the upper lifting oil cylinder and the lower lifting oil cylinder are both parallel to the three chord members. The truss pile leg hydraulic bolt lifting platform is low in assembling precision and easy to manufacture, so that the manufacturing cost of the truss pile leg hydraulic bolt lifting platform is reduced.
Description
technical field [0001] The invention relates to the field of self-elevating offshore platforms, in particular to a truss leg hydraulic bolt lifting platform. Background technique [0002] The jack-up offshore platform is an important mobile platform. The jack-up offshore platform is usually composed of the platform main body, pile legs and lifting system. Among them, the lifting system is a key part of the self-elevating platform. [0003] The existing lifting system includes a truss-type lifting device, and the truss-type lifting device realizes the lifting operation of the self-elevating offshore platform through a rack and pinion. [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 existing truss-type lifting device, the installation and manufacturing precision of the rack and pinion is very high, and it is also necessary to cooperate with the locking mechanism to...
