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 the hoisting crane own wt 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 14 of baseline 9100mm, and the high barrel wall of 2.2m is still arranged on A deck 2 at its top.
Because 813.20 tons of hoisting crane understructure gross weights of the present invention; When dock carried, safe load-carrying ability can reach 700 tons, for guaranteeing safe construction; Must the base of cylinder type be carried out sectional construction; This segmentation should guarantee precision, guarantees that again the intensity of cylinder self is unaffected, also will consider technology and lifting when building.It is the main and normal mode that combines of building that the build process of whole cylinder type base of the present invention has been confirmed as with counter making.
Understructure of the present invention is as depicted in figs. 1 and 2: the base radius of turn is 33m, is the end with main deck 1 with A deck 2, is divided into three layers.Each layer is equipped with deck base plate 3 in its bottom, the equidistant reinforced rib 4 that is provided with on deck base plate 3, and on the deck horizontal direction of base plate 3 is equipped with crossbeam 5, vertical welding transcerse bulkhead 6 on the crossbeam 5; The longitudinal direction of base plate 3 is laid longeron 7 on the deck, vertically is welded with longitudinal bulkhead 8 on the longeron 7.
Outer at above-mentioned base radius is established stiffener 9 straight up, and on the stiffener upper berth barrel plate 10, at base top hoop ring stiffener 11 is arranged.
For main deck 1 can connect, on the cylinder type base on main deck 1 top, have the arch hole, one deck pipe laying slideway 13 is laid in bottom, arch hole.
During fabrication, two schemes are proposed:
First scheme, as shown in Figure 3: the cylindrical shell segmentation is divided by carrying out segmentation up and down, and promptly (main deck 1) is the bottom segmentation from 9100mm A/B platform deck to 14000mm A/B, is designated as the 301B section; (A deck 2) is the top segmentation from 14000mm A/B main deck to 20300mmA/B, is designated as the 301A section.The above part of 301A section is the TUB section, and the TUB section is also as an independently segmentation, and it is built after closing up in 301A, the lift-launch of 301B section dock, sees Fig. 3.The pipe laying slideway structure is built also as a segmentation at last in addition.
The advantage of this scheme is that the 301A section is done as a whole the construction, can be better to precision control, and in addition, its height dimension drops to 6.3m, and handling and sectional turn-over are convenient.Shortcoming is that vertical stiffener 9 has been broken off at segmentation seam place.
Alternative plan; As shown in Figure 4: with tube structure by about carry out segmentation and divide; 2 segmentations about promptly the tube structure on (A deck 2) is divided into from the 9100mmA/B platform deck to 20300mm A/B; Dividing range is at the 200mm place of larboard apart from hull center line face, and larboard one side is the 301C section, and starboard one side is the 301D section.The TUB section of the part of A deck more than 2 is identical with first scheme.
This scheme advantage is that vertical stiffener 9 does not break off, and shortcoming is the segmentation handling, stand up and increased difficulty.
More than two one of schemes be that segmentation up and down, one are left and right sides segmentations, it all has limitation, influence is built.At last, preceding two schemes are merged, compromising the 3rd scheme, as shown in Figure 5:
Be mainly base in the segmentation of carrying out with A deck 2 and 1 two basal planes of main deck, its division step is following:
Bottom segmentation 301B section with 14000mmA/B main deck 1 to the 9100A/B platform deck of tube structure shown in Figure 3; 2 segmentations about being divided into; Apart from hull center line face 200mm place, larboard one side is the 301BC section to its dividing range at larboard, and starboard one side is the 301BD section.
With the 14000mmA/B (main deck 1) of tube structure shown in Figure 3 top segmentation 301A section to 20300mmA/B (A deck 2); 2 segmentations about being divided into equally; Apart from hull center line face 200mm place, larboard one side is the 301AC section to its dividing range at larboard, and starboard one side is the 301AD section.
301AC section and the part above the 301AD section, promptly the 20300mmA/B(A deck 2) above part is as a TUB section independently, no longer divides.
This scheme can be that basal plane is built with the main deck 1 of 14000mm and the A deck 2 of 20300mm respectively with 4 segmentations; Two of the left side sections 301BC sections and 301AC elder generation assembly unit then; The vertical stiffener structure of utilizing crane base self is as template barrel plate 9 in bulk; Lift by crane after standing up on the hull platform; Two segmentation 301BD sections on assembly unit the right and 301AD section then; Lift by crane after standing up on the hull platform, left and right sides two parts are closed piece together again for cylindric; At last, on the cylindric base of moulding, be the bottom with A deck 2, accurately locate vertical stiffener, be template TUB segmentation in bulk barrel plate with vertical stiffener, accomplish the TUB section and build.
This segmentation method had both solved builds choosing of basal plane; Saved the material of extra template; Guarantee the intensity of base, solved again and stood up difficulty, lift by crane difficulty, caused the difficult problem that the base out of roundness is out of shape easily, effectively realized making the accurate construction of goliath base segmentation.
