Problems solved by technology

For a ro-ro ship, the shape of the outer plate is thin and the weight is huge, so that the buoyancy of the ship is always insufficient to support the weight of the hull during the launching process. Before the stern float of the ship starts, because the slideway is supported, there will be no problem, but When the ship leaves the slideway, the lack of buoyancy will cause the ship to have a stern bend and local insufficient strength

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] refer to figure 1 As shown in the structural schematic diagram of the present invention (the accompanying drawing is the right side figure, and the left side figure is symmetrical to it), a kind of ro-ro ship gravity type launching buoyancy tank structure disclosed by the present invention is under the stern hull of the ro-ro ship 1, left and right Respectively increase a pontoon 2 on both sides of the side.

[0017] The pontoon 2 is fixed below the outer plate of the ro-ro ship 1 through a bracket 3, and has a size of 15m*6m*5m. The buoyancy of the two pontoons 2 increases by 842 tons (8.42*106N) in total, while the steel weight of a single pontoon 2 is 18.2 tons, which greatly increases the buoyancy of the stern of the ro-ro ship 1, and effectively solves the local insufficient strength of the bottom of the ro-ro ship 1 and the tail...

Abstract

The invention discloses a structure of a gravity launching buoyancy tank of a roll-on roll-off ship. A launching buoyancy tank is added to each of two sides of the left board and the right board below a ship body at the tail of the roll-on roll-off ship. According to the structure of the gravity launching buoyancy tank of the roll-on roll-off ship, the structure is simple, and the buoyancy force of the tail of the roll-on roll-off ship in the launching process is effectively increased.

Description

technical field [0001] The invention relates to a gravity type launching buoyancy tank structure of a roll-on ship. Background technique [0002] In the prior art, since the berth gravity launching has less investment, simple operation and relatively mature technology, it is widely adopted by shipyards. Conventional ships (such as bulk carriers, container ships, and multi-purpose ships, etc.) are launched, and problems such as stern bending, bow drop, and excessive pressure on the bow fulcrum may generally occur. [0003] Gravity launching of the ship is based on a certain inclination angle of the berth, usually with a slope of 1 / 22. When sliding to a relatively fixed water depth, the hydrodynamic performance of the ship mainly depends on the ship's own weight distribution and the shape of the ship's outer plate Line (shape) decision. For ro-ro ships, the shape of the outer plate is thin and the weight is huge, so that the buoyancy of the ship is always insufficient to sup...
