Hydraulic lifting pile righting guide device for offshore jack-up platform

A hydraulic lifting pile righting guide device for offshore jack-up platform includes a platform support pile, a platform lifting oil cylinder, a lifting ring girder, upper and lower hydraulic bolts, and a fixed lower ring girder. A righting guide sleeve is fitted outside the platform support pile, the lifting ring girder is fitted outside the righting guide sleeve and fixed with the righting guide sleeve, the fixed lower ring girder is fitted outside the platform support pile, the lifting ring girder and the fixed lower ring girder are connected by the platform lifting oil cylinder, the fixed lower ring girder is fixed on the platform body, matching bolt holes are processed at the platform support pile and the righting guide sleeve, the hydraulic bolts are evenly distributed and mounted at the circumferences of the lifting ring girder and the fixed lower ring girder, and a righting adjustment roller group is mounted outside the righting guide sleeve. As a result, the platform support pile is limited in up-and-down movement and can only operate according to the design requirements of people to therefore reduce inclination of the platform support pile, reduce resistance to pile insertion and pullout and improve working efficiency. The invention falls into the field of design and manufacturing process of jack-up platform lifting systems for exploration and exploitation of offshore oil.
