Embodiment

[0020] The embodiment of the present invention provides a self-elevating offshore platform hydraulic bolt lifting system, such as figure 1 with figure 2 As shown, the hydraulic bolt lifting system includes: a moving ring beam 1, a fixed ring beam 2 arranged corresponding to the moving ring beam 1, a bolt 3, and a lifting cylinder 4 installed between the fixed ring beam 2 and the moving ring beam 1, and the fixed ring beam 2 and the moving ring beam 1. The ring beam 2 and the moving ring beam 1 respectively include several crossbeams a connecting end to end. The moving ring beam 1 and the fixed ring beam 2 are equipped with bolt seats 3a, and the bolts 3 are installed in the bolt seats 3a. A lift cylinder pin seat 4a, the pin seat 3a is arranged between the two lift cylinder pin seats 4a on the beam a respectively, and one end of the lift cylinder 4 is installed on the fixed ring beam 2 through the lift cylinder pin 4b. In the oil cylinder pin seat 4a, the other end of the li...

Abstract

The invention discloses a self-elevating offshore platform hydraulic latch lifting system, which belongs to the field of ocean engineering equipment. The self-elevating offshore platform hydraulic bolt lifting system, the hydraulic bolt lifting system includes: a moving ring beam, a fixed ring beam arranged correspondingly to the moving ring beam, a bolt, and a bolt installed between the fixed ring beam and the moving ring beam. There are two lifting cylinder pin seats arranged on the beam, and the pin seats are arranged between the two lifting cylinder pin seats on the beam respectively, and one end of the lifting cylinder is installed on the fixed shaft through the pin shaft of the lifting cylinder. In the pin seat of the lifting cylinder on the ring beam, the other end of the lifting cylinder is installed in the pin seat of the lifting cylinder on the moving ring beam through the pin shaft of the lifting cylinder. The lifting cylinder and the bolt of the hydraulic bolt lifting system provided by the present invention are installed on the same beam, which can reduce the requirements of the beam on the welding seam, so that the requirements for the general welding seam can be used to withstand the force transmitted by the lifting cylinder and the bolt .

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a hydraulic latch lifting system for a self-elevating offshore platform. Background technique [0002] The hydraulic bolt lifting system is applied to the jack-up offshore platform, which can cooperate with the legs of the jack-up ocean platform to drive the hull to move up and down along the legs of the jack-up ocean platform. [0003] The existing hydraulic pin lifting system includes: a moving ring beam, a fixed ring beam, a lifting cylinder, several upper pins on the fixed ring beam, and a number of lower pins on the moving ring beam, wherein the fixed ring beam and the moving The ring beams are connected end to end by multiple beams. The upper and lower pins are installed in the pin seats on the fixed ring beam and the movable ring beam. The pile frame is fixed on the hull, and the fixed ring beam is fixed on the pile frame. One end of the lifting cylinder is ins...
