Truss type supporting structure of heavy full-revolving crane of fan installation ship

Abstract

The invention discloses a truss type supporting structure of a heavy full-revolving crane of a fan installation ship, the structure comprises five main chords and a plurality of horizontal branch chords, and the five main chords enclose a platform body structure with a rectangular cross section; the outer surface of the platform body structure comprises four vertical surfaces; a plurality of horizontal branch chord members are arranged between the adjacent main chord members of each vertical surface; the horizontal support chord members positioned on the same horizontal plane form a horizontalsupport chord member group; horizontal inclined supporting rods are arranged in a rectangular area defined by the horizontal supporting chord member groups; inclined support chord members are arranged between the horizontal support chord members which are adjacent up and down, between the uppermost horizontal support chord member and the upper shell, and between the lowermost horizontal support chord member and the lower shell; and the inclined support chord members are distributed on the vertical surface. The weight of an empty ship is greatly reduced, and the variable load of a deck is effectively controlled; the wind resistance area is greatly reduced, the ship stability is effectively improved, and the ship comfort is improved; and construction is simple, and the construction cost canbe effectively controlled.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a truss-type support structure of a heavy-duty full-slewing crane for a wind turbine installation ship. Background technique [0002] With the gradual strengthening of the awareness of green environmental protection, the offshore wind power market has developed rapidly in domestic and foreign markets, and the installation of offshore wind power has also tended to be high-power and modularized. At present, the lifting capacity of the existing operating ships is far from meeting the market demand for wind turbine installation, and there is an urgent need for heavy-duty full-turn lifting operating ships. [0003] The heavy-duty full-slewing crane, as the key lifting equipment for the operation of the fan installation ship, not only needs to meet the large-diameter fan blades for the lifting installation height requirements (this fan blade needs to meet the distance from the baseline o...

Problems solved by technology

[0007] 2. The large plate support structure greatly increases the wind resistance and seriously affects the stability of the hull;

[0008] 3. When diving and sitting on the bottom, the slab support structure greatly increases the resistance of waves and water flow, which not only increases the design calculation load, but also corresponds to bottom or semi-submersible operations. Since the crane arrangement cannot ensure that it is located in the center of the ship, in the bottom working condition The buoyancy of the launch will generate an additional heeling moment on the slab support structure, seriously affecting the stability of the hull
