An anti-overturn self-elevating platform

Abstract

The invention discloses an anti-overturning self-lifting platform and belongs to the technical field of marine engineering. The platform comprises a hull, a plurality of pile legs and tilting liftingdevices corresponding to each pile leg one-to-one; a strip-shaped through hole is formed in the hull, the direction of the strip-shaped through hole is consistent with the vertical direction of the hull, and the longitudinal direction of the strip-shaped through hole is consistent with the longitudinal direction of the hull; the strip-shaped through hole is provided with the tilting lifting devices; each inclining lifting device comprises a lifting mechanism and a connecting mechanism, and the connecting mechanism is respectively connected with the hull and the lifting mechanism; the angle ofthe direction of the lifting mechanism close to a head (or a tail) of the hull conducting an ascending motion and the direction from the head (or tail) of the hull toward the tail (or head) of the hull is an acute angle; the pile legs are arranged in the lifting mechanism, and the extending direction of the pile legs and the motion direction of the lifting mechanism are the same. The platform canachieve a waste reduction in the construction cost and the design of the platform.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an anti-overturning self-elevating platform. Background technique [0002] The jack-up platform is a kind of marine engineering equipment equipped with multiple functions. It has strong offshore oil and gas production development and support capabilities, and can take into account engineering applications such as offshore construction, offshore wind power installation, bridge erection, hydraulic operations, and island and reef construction. The self-elevating platform includes a hull, a plurality of legs and lifting devices corresponding to the legs one by one. A plurality of legs are distributed on the edge of the hull, and the lifting device is arranged between the corresponding legs and the hull, and the hull or legs can be lifted and lowered freely under the action of the lifting device. During operation, the pile legs extend down to the seabed, stand on the seabe...
