Description
Technical Field
The invention relates to an aluminum helicopter platform structure for ships and maritime workers, in particular to a novel aluminum helicopter platform structure.
Background
Helicopter platforms, commonly known as helicopter decks, are sites for helicopters to land or take off from high-rise land and offshore structures (such as fixed platforms, mobile platforms, ships and the like). In offshore oil and gas development equipment such as mobile platforms, fixed platforms and engineering ships, helicopter platforms are often needed to be arranged in order to effectively realize transportation of materials and personnel.
At present, the common offshore helicopter platform materials mainly have steel structures and aluminum alloy aluminum forms. The main advantage of steel helicopter platforms is low cost and the disadvantage is heavy weight. Aluminum alloy helicopter platforms are lightweight, but costly. The design requirements of the ocean structure are different by adopting different materials.
In the current situation, the proportion of ships and marine helicopter platforms made of steel is large. This is due to several reasons: (1) in the engineering field, the design, construction, detection and installation process and technology of a steel structure are mature; (2) the steel cost is low; (3) the production period of the steel is relatively short; (4) in the design and construction process of the helicopter platform, the design scheme can be modified and adjusted according to the actual situation. Once the aluminum alloy deck is adopted, the coordination of supply manufacturers is needed to modify the deck, the procedure is complicated, and more importantly, the delay of the construction period and the increase of the cost are possibly caused. Therefore, conventional oceaneering equipment is biased to adopt steel structures to build helicopter platforms.
However, as the development of marine oil and gas is gradually moving to deep water and the popularization of new industrial materials, the application of new lightweight materials in marine engineering equipment is a main trend, and the application of aluminum alloy helicopter platforms is an important content.
Compared with a steel helicopter platform, an aluminum helicopter platform has the following main advantages: (1) maintenance-free: the aluminum alloy which does not require surface protection treatment in the marine environment is properly selected, an oxide layer with a protection function can be rapidly formed, and the metal is protected from corrosion. The aluminum alloy can be continuously used for more than 70 years in a marine environment under the condition of no maintenance; (2) the weight is small: compared with a steel helicopter platform, the weight of the aluminum helicopter platform is about 35% -50% of that of the steel helicopter platform.
However, if the entire helicopter platform is made of aluminum alloy, the following disadvantages are caused: (1) as for the steel helicopter platform, the strength of the aluminum helicopter platform is weak, and in order to meet the overall strength of the helicopter platform, the number of lower support parts is more than that of the steel helicopter platform, which is not beneficial to the overall arrangement and planning of the platform structure; (2) the structure of an all-aluminum helicopter platform is usually connected through welding, and the whole helicopter platform is large in structure and inconvenient to transport.
Disclosure of Invention
In order to solve the problems, the invention discloses a novel aluminum helicopter platform structure.
The technical scheme of the invention is as follows: the utility model provides a novel aluminium system helicopter platform structure, includes horizontal frame and helicopter deck, and horizontal frame is formed through bolted connection by the horizontal beam, and the helicopter deck forms through deck piece concatenation, and the helicopter deck passes through clamp plate and bolt fastening on horizontal frame, and horizontal frame is connected through the steel bracket of bolt and below.
Furthermore, the horizontal beam comprises vertical beams and girth beams, the vertical beams and the girth beams are at the same height, the adjacent girth beams are connected through bolts to form a girth beam frame, the vertical beams are connected through bolts, and the horizontal frame is formed by the bolts and the girth beams.
Furthermore, the deck block comprises an upper top plate and a lower bottom plate, a cavity with a rib plate is arranged between the upper top plate and the lower bottom plate, the upper top plate is of a tongue-and-groove plate structure, and connecting parts used for fixing the deck block on the horizontal frame extend from two sides of the lower bottom plate.
Further, the horizontal frame and the helicopter deck are both made of aluminum.
The invention has the advantages that: adopt aluminum alloy section bar to constitute helicopter platform structure, all aluminum alloy section bars pass through bolted connection, have accomplished to subtract heavy and be convenient for transport under the condition that satisfies helicopter platform bulk strength.
