The specific embodiment
Referring to Fig. 1～Fig. 5, the present invention plans to build heavy ocean engineering hoisting crane base and is positioned at the hull afterbody, and himself weight is 4000 tons.During the stern fixed mode, radius of turn is 43m, and load-carrying ability is 4000 tons; During the full circle swinging pattern, radius of turn 33m, load-carrying ability are 3500 tons.
Planning to build the hoisting crane base is that diameter is the cylinder type of 24.3m, and it highly is 13.40m, and cylindrical shell top is that wall thickness is the steel plate of EH36-Z35 for the 45mm material, and the bottom is that thickness of slab 30mm and 45mm material are the steel plate of EH36.The cylindrical shell bottom is welded on the platform deck 14 of baseline 9100mm, and the high barrel wall of 2.2m is still arranged on A deck 2 at its top.
Concrete understructure is referring to Fig. 1 and Fig. 2: be basal plane with main deck 1, be equipped with deck base plate 3, the equidistant reinforced rib 4 that is equipped with on deck base plate 3; Horizontal direction at described deck base plate 3 is laid crossbeam 5, establishes transcerse bulkhead 6 at crossbeam 5; Longitudinal direction at deck base plate 3 is laid longeron 7, establishes longitudinal bulkhead 8 at longeron 7; 58 vertical stiffeners 9 of peripheral equidistant welding of (main deck 1, A deck 2 and platform deck 14) on the deck are laid barrel plate 10 at stiffener 9.Described barrel plate 10 is 16mm * 750mm, and panel is 25mm * 250mm, and it is initial from 9100mm platform deck 14, passes through main deck 1, and the lower surface on A deck 2 ends.Be provided with the high superstructure TUB of 2.20m above the A deck 2, stiffener 9 also is set on the barrel wall of superstructure TUB, highly be 2.20m, stiffener 9 corresponding align below A deck 2, hoop has circular ring stiffener 11 at the top of the stiffener 9 of superstructure TUB, also is equipped with barrel plate 10 on this stiffener 9.
813.20 tons of hoisting crane understructure gross weights of the present invention, when dock carried, safe load-carrying ability can reach 700 tons.
The construction assemble method of hoisting crane base of the present invention comprises following three kinds of schemes:
First scheme: the base segmentation is divided by carrying out segmentation up and down, is the bottom segmentation from 9100mm A/B platform deck to 14000mm A/B main deck 1 namely, is designated as 301B; From 14000mm A/B main deck 1 to 20300mmA/B(A deck 2) be the top segmentation, be designated as 301A.The top of 301A segmentation is the TUB segmentation, and the TUB segmentation is also as an independently segmentation, and it is built after closing up in 301A, the lift-launch of 301B segmentation dock, sees Fig. 1-Fig. 3.
This scheme advantage is that as a whole the construction done in the 301A segmentation, can be better to precision control, and in addition, its height dimension drops to 6.3m, and handling and sectional turn-over are convenient, and shortcoming is that vertical stiffener 9 has been disconnected at segmentation seam place.
Alternative plan: with understructure by about carry out segmentation and divide, namely from the 9100mmA/B platform deck to 20300mm A/B(A deck 2) tube structure be divided into about 2 segmentations, dividing range is at the 200mm place of distance larboard apart from hull center line face 0, larboard one side is the 301A segmentation, and starboard one side is the 301B segmentation.Three-decker TUB segmentation is the same with first scheme, sees Fig. 1, Fig. 2 and Fig. 4.
This scheme advantage is that vertical stiffener does not disconnect, and shortcoming is the segmentation handling, stand up and increased difficulty.
Third party's case of the present invention:
The first step, the hoisting crane base is carried out segmentation:
See Fig. 5, base is divided into three sections up and down according to understructure, middle level structure and superstructure after, carry out left and right sides segmentation again.Specifically: namely from 9100mm A/B(platform deck 14) to 14000mm A/B main deck 1 be understructure, be designated as 301B; From 14000mm A/B main deck 1 to 20300mmA/B(A deck 2) be the middle level structure, be designated as 301A; 2 parts about again middle level structure 301A and understructure 301B being divided into, dividing range is at the 200mm place of distance larboard apart from hull center line face; The middle level of larboard one side and half one of lower floor are respectively 301AC section and 301BC section, and the middle level of starboard one side and half one of lower floor are 301AD section and 301BD section.
Superstructure TUB as an independently segmentation, and is carried at 301A, 301B segmentation dock and to build after closing up.In addition, also with the L5(PS of the both sides, center of base lower end) and L5(SB) between the pipe laying slideway structure also separately as a segmentation, also be to carry at 301A, 301B segmentation dock to build after closing up.
Second step was respectively 301AC section and 301BC section with above-mentioned middle level and lower floor left side, and the right-hand part of middle level and lower floor is that (except TUB segmentation and pipe laying slideway structure) assembled in 301AD section and the segmentation of 301BD section, and is specific as follows:
With above-mentioned four segmentation hoisting crane bases that are divided into main deck 1 and A deck 2 anti-assembling respectively simultaneously, counter being assembled into: be anti-left side 301BC section and the right-hand part 301BD that makes understructure 301B in the end with 14000mm A/B main deck 1, the port and starboard symmetry, build respectively, but stiffener 9 and barrel plate 10 are not installed.
And then be counter left side 301AC section and the right-hand part 301AD branch of making middle level structure 301A in the end with A deck 2; Subsequently for carrying out segmentation seam place tack welding between left side, middle level 301AC section and the lower floor's left side 301BC section; To carry out segmentation seam place tack welding between 3 middle level right-hand part 301AD and the right-hand part 301BD of the lower floor section again, and two halves base in aggregates after the tack welding is carried out 180 ° stand up.Two and half bases after righting are transferred to respectively on the hull platform deck 14, after being assembled into a cup dolly, 58 vertical stiffeners 9 conducts of peripheral equidistant welding at platform deck 14 are supported, and the shape that surrounds by stiffener outside stiffener 9 is at last laid the barrel plate 10 of 16mm * 750mm in flakes.This laying is initial from 9100mm platform deck 14, passes through main deck 1, and the lower surface on A deck 2 ends.At last, middle level structure 301A is directly carried out the assembling of superstructure TUB section with top in dock, form complete cylindrical structural.
The three-decker assemble method of base of the present invention is identical with said method, is example with middle level right-hand part 301AD section now, provides the concrete inside construction step of each part:
Be basal plane with main deck 1, lay deck base plate 3, equidistant welding reinforced rib 4 on deck base plate 3.Lay crossbeam 5 at the horizontal direction of deck base plate 3 then, on crossbeam 5, vertically weld transcerse bulkhead 6; Equally, lay longeron 7 at the longitudinal direction of deck base plate 3, on longeron 7, vertically weld longitudinal bulkhead 8.After handling above-mentioned steps, the anti-assembling of each independent segmentation finishes.
The 3rd step: superstructure TUB segmentation and the pipe laying slideway structure of A deck more than 2 carried out last assembling.
After more than construction finished, the cylinder base namely installed.
