Abstract

The invention discloses a self-lifting semi-submersible type underwater working platform which comprises a main ship body, a lifting mechanism, a plurality of buoyancy tanks and at least four pile legs. The lifting mechanism is fixedly installed on the main ship body, and the lifting mechanism is connected with the four pile legs in a matched mode and can drive the main ship body to slide longitudinally along the pile legs. The buoyancy tanks are symmetrically installed on the main ship body, and a main deck penetrating through the main ship body in the front-back direction is formed on the upper side face of the main ship body. By the adoption of the technical scheme, the self-lifting semi-submersible type underwater working platform is simple in structure and easy to obtain, the position of the main deck can be adjusted vertically to be flush with a wharf shore foundation, and the position of the main deck is prevented from being influenced by the wharf height and tide level change; and in addition, in the horizontal movement loading and unloading process, the pile legs are inserted so as to achieve a supporting function, the main deck is kept flush with the wharf shore foundation all the time, complex operation of load adjustment of floating shipping is avoided, and the defects of a wide tidal range, a fast tide level change and a large wharf height difference can be overcome.

Description

technical field [0001] The invention relates to the technical field of ship design and manufacture, in particular to a working platform for self-elevating and semi-submersible launching Background technique [0002] With the gradual development of marine transportation in the trade and transportation of various countries, the ship design and manufacturing industry has also gradually developed. In shipbuilding, it is usually done for flat shipbuilding, and then the translation devices such as slide shoes and wheel rails are used to move the product to and from the working boat, including floating docks, semi-submerged barges, etc. to complete the launching. Translational shipping requires that the main deck of the launching workboat be flush with the wharf, or the height difference be controlled within a reasonable range to ensure the flatness of the slide rails. The traditional way of launching is mainly to set up underwater buttresses or to use floating loading, among whic...
