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
The present invention relates to a kind of roll-on-roll-off ship gravity launching floating box structure.
Background technology
In the prior art, because the investment of building berth gravity launching is less, simple to operate, technical matters is comparatively ripe, is extensively adopted by shipyard.The lower water of conventional boats and ships (such as bulge carrier, box ship and multi purpose ship etc.), the problem such as may occur generally that tail is curved, head falls and the stem dead-end pressure is excessive.
Adopt building berth gravity launching boats and ships, be based on the certain angle of inclination of building berth, usually adopt 1/22 gradient, sliding in the relatively-stationary situation of the depth of water, the own wt that launching hydrodynamic(al) performance depends primarily on boats and ships distributes and ship plank molded line (shape) decision.For the picture roll-on-roll-off ship, its outside plate shape is very thin, weight is very big, causes in the launching process, is in all the time buoyancy and is not enough to support hull weight, before the floating beginning of boats and ships tail, because slideway bears support, can not go wrong, but after boats and ships leave slideway, the buoyancy deficiency will make boats and ships exist tail curved, the not enough problem of local strength.
Therefore, the full-sized car roll-on-roll-off ship is because the speed of a ship or plane is high, hull lines are very thin, ship hull plate and the feature such as the deck is thinner, the boats and ships own wt is larger, water problem is more complicated up and down so that it is at building berth, except the problem that conventional launching may occur, afterbody buoyancy deficiency also occurs and cause the phenomenons such as hull bottom local strength is not enough, boats and ships generation tail is curved.
Defects in view of water under the prior art full-sized car roll-on-roll-off ship, the inventor increases floating box structure at the boats and ships afterbody in the situation that can't increase after draft, afterbody buoyancy increases when making under the roll-on-roll-off ship water, solve the problem that water exists under the roll-on-roll-off ship, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of roll-on-roll-off ship gravity launching floating box structure simple in structure and afterbody buoyancy when effectively increasing water under the roll-on-roll-off ship.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of roll-on-roll-off ship gravity launching floating box structure, below the afterbody hull of roll-on-roll-off ship, the port and starboard both sides respectively increase a buoyancy tank.
Further, buoyancy tank is fixed on the below of roll-on-roll-off ship outside plate by support, and size is 15m*6m*5m.
After adopting such scheme, the present invention is below the afterbody hull of roll-on-roll-off ship, and the port and starboard both sides respectively increase a buoyancy tank, so that roll-on-roll-off ship is after leaving slideway, increase roll-on-roll-off ship afterbody buoyancy, effectively solve under the roll-on-roll-off ship water and the problems such as bottom local strength's deficiency and tail be curved occur.
Description of drawings
Fig. 1 is structural representation of the present invention.
Label declaration
Roll-on-roll-off ship 1 buoyancy tank 2
The specific embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
Consult (accompanying drawing is right part of flg, and left hand view is symmetrical with it) shown in Fig. 1 structural representation of the present invention, a kind of roll-on-roll-off ship gravity launching floating box structure that the present invention discloses, below the afterbody hull of roll-on-roll-off ship 1, the port and starboard both sides respectively increase a buoyancy tank 2.
The above is preferred embodiment of the present invention only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
Claims (2)
1. roll-on-roll-off ship gravity launching floating box structure, it is characterized in that: below the afterbody hull of roll-on-roll-off ship, the port and starboard both sides respectively increase a buoyancy tank.
2. a kind of roll-on-roll-off ship gravity launching floating box structure as claimed in claim 1 is characterized in that: buoyancy tank is fixed on the below of roll-on-roll-off ship outside plate by support, and size is 15m*6m*5m.
