Problems solved by technology
The traditional self-elevating platform has a complex structure and is inconvenient to operate. The positioning columns are generally solid. The solid positioning columns mainly consider the compression resistance after being inserted into the seabed. However, due to the long length of the positioning columns, the positioning columns The weight of the barge is relatively large, so the barge in the floating state needs to have a lot of buoyancy to ensure that the barge can float on the water, so the requirements for the manufacture of the barge are very high, or it can only be equipped with shorter positioning columns, so that the self-elevating The platform can only be used in shallow waters

The invention discloses an offshore platform which comprises a barge and positioning columns. First through holes are formed in the barge, a lifting mechanism is arranged above each first through hole, and the positioning columns are arranged in the lifting mechanisms and the first through holes in a penetrating mode; each lifting mechanism comprises two first panels, the two first panels are connected together through a plurality of first hydraulic cylinders, second through holes used for penetrating through the positioning columns are formed in the two first panels, the two sides of each second through hole are respectively provided with a supporting frame, the supporting frames are fixed on the first panels, tooth blocks are hinged to the supporting frames, each tooth block is in a bent shape, second hydraulic cylinders are hinged to the tooth blocks, and the second hydraulic cylinders are hinged to the first panels; each positioning column comprises a column type steel structure frame body, a plurality of supporting rods are arranged in the frame bodies, racks are arranged on two opposite outer side faces of each frame body, and the tooth blocks are matched with the racks. The offshore platform is simple and convenient to control, and the barge of the same kind can bear longer supporting rods and can work in a deeper sea area.
Description
technical field [0001] The invention relates to the technical fields of marine engineering and shipbuilding, in particular to an offshore platform. Background technique [0002] With the development of science and technology, human beings gradually explore the ocean for resources, and when exploring resources, it is necessary to set up offshore platforms at sea. Offshore platforms mainly include fixed offshore platforms and floating offshore platforms. [0003] The fixed offshore platform has a fixed position throughout its service life, and its forms include pile type, guy rope type and gravity type, etc. The piled platform consists of caps and pile foundations. Pile foundations include wooden piles, steel piles and reinforced concrete piles, etc., which are driven into the seabed during construction, and caps are installed on it. The rope-type platform, also known as the mooring tower platform, is formed by placing a prefabricated steel tower on the foundation block of t...
