Detailed description of the invention
The structure that Figure of description illustrates, ratio, size etc., content all only in order to coordinate specification sheets to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, is not affecting under effect that the present invention can produce and the object that can reach, and all should still drop in scope that disclosed technology contents can contain.Simultaneously, quote in this specification sheets as " on ", D score, "front", "rear", the term such as " centre ", also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
As shown in Fig. 1 to Fig. 7, wherein Fig. 1 and Fig. 2 is the installation cooperation structure schematic diagram of liquid tank 1 and hull 2, and wherein the Width of liquefied gas carrier is laterally; Fig. 3-Fig. 7 is installing condition schematic diagram of the present invention.Described liquid tank 1 is arranged in the hull 2 of large-scale liquefied gas carrier, and the bottom surface of liquid tank 1 is provided with the anti-rolling bearing 3 of multiple outwardly convex, and described hull 2 base plate is provided with and coordinates the spacing bearing of anti-rolling with anti-rolling bearing 3.The two ends, left and right of described anti-rolling bearing 3 are provided with vertical driving surface, described driving surface surrounds an oblong framework by three pieces of adapter plates 6 and one piece of portable plate 7, the spacing bearing of described anti-rolling comprises the limit body 41 that two transverse directions are oppositely arranged, 42, described limit body 41, position-limited trough is formed between 42, described anti-rolling bearing 3 card is placed in position-limited trough, the limit body 41 of described anti-rolling bearing 3 and the spacing bearing of anti-rolling, 42 coordinate after in described framework placed layer pressed wood 5, the width of described framework and be highly greater than the width of lamination wood 5 and height so that install and coordinate.For in crane lifting liquid tank 1 to hull 2 in the present embodiment, the installation of described lamination wood 5 comprises the following steps:
First preliminary examination cleaning is carried out to the framework at anti-rolling bearing 3 two ends, impurity in framework is cleaned out, then described liquid tank 1 is hung in hull 2 by crane, and in the position-limited trough that anti-rolling bearing 3 will be made to be stuck between anti-rolling spacing bearing two limit body 41,42.Because now lamination wood 5 is not installed, so need to adjust distance between anti-rolling bearing 3 two ends driving surface and limit body 41,42 by crane, guaranteeing all can mounting layer pressed wood 5 between anti-rolling bearing 3 two ends driving surface and limit body 41,42.When distance between anti-rolling bearing 3 two ends driving surface and limit body 41,42 can meet the installation requirement of lamination wood 5, the impurity such as rust staining, welding slag and greasy dirt whether are had in the framework again checking anti-rolling bearing 3 two ends, to clear up in time if had, guarantee in anti-rolling bearing 3 framework clean further.
After anti-rolling bearing 3 and the spacing bearing of anti-rolling are worked good, be placed into by lamination wood 5 on a billy gate 8, lamination wood 5 is transported near the installation site between the driving surface of anti-rolling bearing 3 and limit body 41,42 by billy gate 8.In the present embodiment, in order to ensure precision when installing, prevent from repeating adjustment, before lamination wood 5 is transported to installation site, need the actual installation height measuring lamination wood 5, the billy gate 8 of different size can be selected to reach requirement for height according to the actual installation height of lamination wood 5, or on billy gate 8, arrange hoist cylinder to adjust height.Billy gate 8 top described in the present embodiment is provided with many row's rollers 81, and described lamination wood 5 is placed on described roller 81, can be facilitated the movement of lamination wood 5 by roller 81.Described billy gate 8 is also provided with brake gear 82.
After billy gate 8 reaches installation site, by brake gear 82, billy gate 8 is fixed on original place, prevents the billy gate 8 when mobile mounting layer pressed wood 5 unstable.Composition graphs 2,6,7, the driving surface of portable plate 7 from the spacing bearing limit body 41,42 of anti-rolling is pulled down, it is inserted in the framework driving surface by staff's push layer pressed wood 5 from the side that portable plate 7 is pulled down, because lamination wood 5 is placed on roller 81, so more laborsaving when push layer pressed wood 5 moves.Composition graphs 2,4,7, the position of observed layer pressed wood 5 at any time will guarantee the midway location of lamination wood 5 in framework in the process of insert layer pressed wood 5.Portable plate 7 is reinstalled on the driving surface of anti-rolling bearing limit body 41,42 after determining by lamination wood 5 positions, removes billy gate 8 simultaneously.
Composition graphs 2,3,5, after portable plate 7 installs, the thick dividing plate of 2mm 9 is placed between lamination wood 5 and the limit body 41,42 of the spacing bearing of anti-rolling, through the tapped bore 32 on anti-rolling bearing 3 driving surface lamination wood 5 to be released laterally with bolt and lean on dividing plate 9, but lamination wood 5 can not drop from framework.Composition graphs 2,5,7, with adhesive tape (not shown) by the gap shutoff between lamination wood 5 and framework, and by the plug hole 31 on anti-rolling bearing 3 to casting epoxy resin between lamination wood 5 and limit body 41,42, dividing plate 9 is removed, the installation location of complete layer pressed wood 5 after epoxy resin cure.To be that friction when preventing real work between anti-rolling bearing 3 and limit body 41,42 is excessive cause serious wear in the 2mm gap arranged between anti-rolling bearing 3 and limit body 41,42, and then reduction of service life.
Dividing plate 9 described in the present embodiment is stainless steel sheet or polyethylene board.
In sum, the installation method of the liquid tank anti-rolling bearing middle level pressed wood of liquefied gas carrier of the present invention, can solve the problem that prior art middle level pressed wood is installed difficulty, wasted time and energy.So the present invention effectively overcomes practical problemss more of the prior art thus has very high value and use meaning.
Above-mentioned embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.The present invention also has many aspects can improve under the prerequisite of overall thought, all without prejudice under spirit of the present invention and category, can modify above-described embodiment or change for person skilled in the art scholar.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
