Detailed description of the invention
In order to more clearly understand technology contents of the present utility model, below specific implementation method of the present utility model is described further.
As shown in figures 1 to 6, the Large LNG ship Type B containment system of the present embodiment only shakes device 10, and this only shakes the top of device 10 as containment system, comprises, and lower back-up ring, is located at lamination flitch 1 inside lower back-up ring and wedge in the overhead gage on lamination flitch 1 top,
Wherein, lamination flitch 1 inside is embedded with metallic material 9;
Overhead gage comprises bracket 4 and top panel 7, lower back-up ring comprises lower bracket 5 and lower faceplate 8, the first space is provided with between lamination flitch 1 top dual-side and upper bracket 4, Second gap is provided with between the two bottom sides limit of lamination flitch 1 and lower bracket 5, the 3rd space is provided with between the bottom of lamination flitch 1 and lower faceplate 8, the 4th space is provided with between the front and back dual-side of lamination flitch 1 and lower bracket 5, all be embedded with in stopper layer pressed wood voussoir the 2, three space and the 4th space in first space and Second gap and be cast with low temperature resistant epoxy 3.
Only shake between device 10 and containment system and bondd by low temperature resistant epoxy.Only shake device 10 surrounding and be equipped with insulation screen 6, metallic material 9 is low temperature resistant metallic material.
The quantity of only shaking device 10 decides according to the length in cabin.
Between the crossbeam panel only shaking device 10 top and hull, there is space.
Its installation procedure is each component first obtaining back-up ring under installation on strong frame component at containment system top center position, and component installation location is shown in Fig. 3 and Fig. 5, according to cabin is long, single containment system can determine that length direction need install the quantity of only shaking device 10;
Down back-up ring (in the groove surrounded by lower bracket and lower faceplate) pours the thick low temperature resistant epoxy of 10mm into, again lamination flitch is put in groove, bottom flitch, between Y-direction (hull system of axes) and lower back-up ring panel, the space of 40mm embeds stopper layer pressed wood voussoir, and bottom flitch, between X-direction (hull system of axes) and back-up ring panel, the space of 20mm is poured into a mould with low temperature resistant epoxy;
Each component of installation overhead gage on ship flying deck reverse side crossbeam, component installation location is shown in Fig. 4;
After containment system lifting puts in place, during installation ship flying deck, overhead gage just buckles into above flitch, after treating deck construction welding, between overhead gage and flitch, space embeds stopper layer pressed wood voussoir in the Y direction, and the space that between flitch top and hull crossbeam panel, reserved 50mm is high is for discharging the vertical floating distortion of whole containment system.
Last lay certain thickness insulation screen and reduce liquid goods rate of evaporation as far as possible only shaking device 10 surrounding again, design sketch is shown in Fig. 1.
The all parts design of the utility model device:
Lamination flitch is as stressed main body and " stndon sheath ", its selection there are certain requirements, the vertical compressive strength of the dehonit series layer pressed wood that such as Germany produces reaches 235MPa, shear strength reaches 56MPa, be chosen as the main material of lamination wood, derby material in flitch can adopt high strength steel stack in flitch with strength adhesive bonding closely, the thin plate that one piece of same material also respectively can be welded in the exposed both ends of steel heap X-direction carries out edge sealing process, steel is combined tightr.
Overhead gage is made up of certain thickness two groups of high strength steel top panels and upper bracket, and bracket and panel are welded on deck in ship structure reverse side crossbeam panel central authorities, and bracket line of centers aligns with the web of crossbeam, see accompanying drawing four.
Lower back-up ring is made up of certain thickness four groups of high strength steel lower faceplates and lower bracket, four pieces of panels surround four square grooves, bracket line of centers in Y-direction and containment system strong frame structure alignment, bracket line of centers in X-direction aligns with containment system centerline bulkhead, respectively one piece of little bracket is welded again outside the X, Y-direction at four angles place of square groove, totally eight pieces of little brackets, the reverse side line of bracket all installs reinforced rib, see Fig. 5 and Fig. 6.
The choice requirement of stopper layer pressed wood voussoir is the same with lamination flitch or slightly high, and its thickness can adjust according to the actual gap of lamination flitch and overhead gage and lower back-up ring, closely to wedge as principle.
Epoxy type is a lot of, and epoxy selected by the present embodiment device requires that low-temperature properties is well stable, cohesiveness is strong, have the type of some strength after solidification, extremely has practicality.
Fig. 7 is that the utility model embodiment Large LNG ship Type B containment system only shakes installation site, device 10 single storehouse design sketch.
Fig. 8 is that the utility model embodiment Large LNG ship Type B containment system only shakes the distribution graph of device 10 on liquid tank top.Known to Fig. 7 and Fig. 8, the installation site that this Large LNG ship Type B containment system only shakes device 10 and the point worked.
The Large LNG ship Type B containment system of the utility model embodiment is adopted only to shake device, there is good thermo-insulation properties, when containment system produces rolling moment due to ship motion, the rolling power that containment system top rolling motion produces is passed to lamination flitch by lower back-up ring and is passed to the overhead gage be installed in hull beam again by lamination flitch, the application force of containment system rolling is offset by the support reaction utilizing hull structural member to produce, lamination flitch body then local bears positive pressure and shearing force, the stopper layer pressed wood block embedded fits tightly pressurized generation friction force can prevent flitch catenary motion, ensure that lamination flitch Impact direction is stablized.The good mechanical properties of lamination wood, similar with common iron, but the vertical shearing stress allowable of such lamination flitch is 35 to 56MPa, and steel shearing stress 110MPa allowable, in order to improve the anti-shear ability of flitch, at flitch central part embedded part metallic material, then utilize strength adhesive by both in conjunction with close and firm, such flitch just possesses enough resistance to compressions and resistance to shear simultaneously.Device described in this makes simple, easy for installation.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets is regarded in an illustrative, rather than a restrictive.
