Description of drawings
Fig. 1 is the integral hoisting scheme drawing of ship superstructure;
Fig. 2 is whole continuous type four eyed Lifting Lug Structure scheme drawing.
The specific embodiment
Below in conjunction with concrete accompanying drawing the present invention is done further explanation.
With the 118000DWT bulge carrier is example; The integral hoisting method of brief account ship superstructure; As shown in Figure 1, first-selection is provided with whole continuous type four eyed hanger 3, every hanger lift heavy 50t at superstructure segmentation bridge wing deck two side enclosure wall (11050 peripheral walls in the distance) front end, leg two ends, back; Simultaneously 4 40t standard hangers 3 are set in chimney 4 left sides of superstructure 2; The right side is provided with 6 40t standard hangers, and the front side is provided with 4 40t standard hangers, and 2 40t standard hangers are set on the deck of chimney.For guaranteeing that suspension centre power actv. is delivered to lower tween deck, must strengthen shackle structure, as shown in Figure 2, the preferred reinforcement version 5 that increases is strengthened.CO is adopted in suspension ring and deck welding
2Gas shield welding or basic electrode welding, the beveling of the edge complete penetraction and fusion in welding, all the vertical, horizontal frameworks in the 1m scope of the back side, suspension ring zone all need add fierce, promptly on the basis of former foot welding height, increase leg 3 ~ 5mm.
It also is the most complicated part that the superstructure overall construction intensity is checked most crucial when being integral hoisting; Because being installed, the position of hanger bears whole superstructure overall weight, if this position insufficient strength then can produce local yielding; Cause plastic deformation, can occur tearing under the serious situation; Simultaneously, to superstructure generally speaking, hanger position pulling force upwards; And the superstructure gravity direction is downward, makes structure produce additional bending moment, when moment of flexure surpasses the load that structure can bear; Structure can produce flexural deformation, and when serious, the plastic deformation that moment of flexure produces can't be recovered; In addition, the flexural deformation meeting of structure causes the relative weak part of interior section to produce destruction etc.Therefore, the strength check key to the superstructure structure during lifting is to strengthen hanger position intensity, in case tear and two aspects of control structure distortion.The superstructure hoisting process mainly considers to receive the static(al) effect, for the short-cut calculation process, ignores influences such as door opening, and each lower tween deck, inner bulkhead etc. are regarded as dividing plate, and calculates with the least favorable load situation, helps the safe design of hoisting process.Wherein, concentrated load is born at the hanger position, can directly carry out the static(al) Calculation and Analysis of Force, carries out the design of hanger position Structural Strength Design and fusion length then in view of the above.And complicated to other position of superstructure stress deformation situation in hoisting process, the finite element model of simplifying is set up in superstructure, adopt PLAN42 to carry out grid and divide; Structural weight is converted into uniform load to load on the box type construction; Carry out the finite element static(al) then and find the solution, for knowing display graphics, the distortion situation on deck, intercepting hanger place; Can find out because the hanger position makes progress the distortion vertically upward of stressed generation with by the distortion of action of gravity downward direction.Analysis shows superstructure because most of structure relative deformation that lifting causes is little, can not destroy interior dress, and result of finite element shows that structural strength meets the demands.Distribution of stress on each layer deck and the leg is with maximum with the bridge deck upper stress near the leg hanger, and littler toward lower floor's deck stress, regional area need be strengthened.Need strengthen near leaning in the ship like the leg end opening under hanger place regional area, the orlop deck.In addition, also can draw hole location and have the stress concentration situation, but each layer watertight door, window need not carry out extra reinforcing because of self metal door frame, window frame plays booster action.
The integral hoisting method of ship superstructure of the present invention; Improve labour intensity, increase productivity, shorten ship building period; Time on building berth, shortened in special realization, the outfitting cycle; Thereby shorten total cycle of shipbuilding, have good practicability, can produce good economic benefits and social benefit.
