Description
Technical field
The present invention relates to a kind of explosion-proof hatch cover.
Background technology
Hatch cover (hereinafter referred to as hatchcover) is one of important component part on boats and ships.Hatchcover is the closing appliance of hold deck opening.It bears plug hatch, the effect of protection goods and part support platform.Hatchcover body mostly is large-scale steel structure, and the accessory device of outfit is machine up component, drive and control mode varied.The intensity of hatchcover and close property, have influence on the safety of boats and ships; The on-off mode of hatchcover, has influence on the time of handling goods; Hatchcover body, annex and driving arrangement occupy significant proportion in shipbuilding cost, are related to the economy of boats and ships.Hatchcover is more and more paid attention to by classification society, shipowner and shipyard for this reason.Hatchcover repair also becomes impact one of single ship repairing quality and the priority project of duration.If hatchcover divides according to on-off mode, hatchcover can be divided into: rolling type, collapsible, side shifting type, lift-on/lift-off type and spool type etc.If divided according to type of drive, can be divided into again: chain-type, hinge type, rack-and-pinion and rod-pulling type etc.Rolling type hatchcover.The multiplex situation longitudinally larger at hatch opening of hatchcover of this form.Each hatch is combined by the little hatchcover of polylith, and between hatchcover, chain connects, and monolithic hatchcover length is less, and there is walking roller both sides, walking of can rolling on the track of hatch coaming horizontal plate.The space of depositing hatchcover is had before and after hatch.The feature of this hatchcover is: hatchcover is flexibly small and exquisite, easy to maintenance.But limit by load, hatch coaming height, condition such as collection rail length etc., be unfavorable for that modern ships maximizes, the demand for development of specialized and high-mobility, multipurpose, wheeled vehicle.Fade out the ship hatchcover arena of history now just gradually.
Summary of the invention
The invention provides a kind of there is withstanding corrosion, nonmagnetic, intensity is high and the explosion-proof hatch cover of explosion-proof advantage.
Technical scheme of the present invention is: a kind of explosion-proof hatch cover, described explosion-proof hatch cover comprises the alloy in lightweight layer of the superiors, the adhesive of interlayer and undermost superalloy layer and combines, described alloy in lightweight layer comprises aluminum lithium alloy, described superalloy layer is nickel cobalt (alloy), described alloy in lightweight layer accounts for the 41%-49% of the overall component of explosion-proof hatch cover, described adhesive accounts for the 9%-13% of the overall component of explosion-proof hatch cover, and described superalloy layer accounts for the 41%-47% of the overall component of explosion-proof hatch cover.
In a preferred embodiment of the present invention, described adhesive is chlorohydrin rubber.
In a preferred embodiment of the present invention, described alloy in lightweight layer accounts for 47% of the overall component of explosion-proof hatch cover, and described adhesive accounts for 11% of the overall component of explosion-proof hatch cover, and described superalloy layer accounts for 42% of the overall component of explosion-proof hatch cover.
A kind of explosion-proof hatch cover of the present invention, has withstanding corrosion, the advantage that nonmagnetic, intensity is high and explosion-proof.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, described explosion-proof hatch cover comprises the alloy in lightweight layer of the superiors, the adhesive of interlayer and undermost superalloy layer and combines, described alloy in lightweight layer comprises aluminum lithium alloy, described superalloy layer is nickel cobalt (alloy), described alloy in lightweight layer accounts for the 41%-49% of the overall component of explosion-proof hatch cover, described adhesive accounts for the 9%-13% of the overall component of explosion-proof hatch cover, and described superalloy layer accounts for the 41%-47% of the overall component of explosion-proof hatch cover.
Further illustrate, described adhesive is chlorohydrin rubber, described alloy in lightweight layer accounts for 47% of the overall component of explosion-proof hatch cover, and described adhesive accounts for 11% of the overall component of explosion-proof hatch cover, and described superalloy layer accounts for 42% of the overall component of explosion-proof hatch cover.Aluminum lithium alloy has high specific strength (disruption characteristic/density), high specific stiffness and the little feature of relative density, and as being used as present generation aircraft skin material, a frame airliner can expendable weight 50 kg.For Boeing-747, often alleviate 1 kg, within 1 year, can make a profit 2 000 dollars.Titanium alloy is lighter than steel, withstanding corrosion, nonmagnetic, intensity is high, is the ideal material for aviation and naval vessels.
Further illustrate, in general, the fusing point of superalloy is higher again, and its spendable temperature margin is higher.As represented fusing point by thermodynamic temperature, then melting point metal Tm 60%, being defined as in theory can serviceability temperature upper limit Tc, i.e. Tc=0.6Tm.This is because along with the rising of temperature, the mechanical characteristics of metallic material significantly declines, the corresponding increase of trend of oxide etch, therefore, general metallic material all can only long-term work at 500 ~ 600 DEG C, the metal common name heat resistant alloy that can work under >700 DEG C of high temperature, " heat-resisting " refers to that it at high temperature can keep enough and intensity and good inoxidizability.The approach improving iron and steel inoxidizability has be in steel add the alloying elements such as Cr, Si, Al at two: one, or carries out Cr, Si, Al Alloying Treatment on the surface of steel.They can generate the fire coat of one deck densification very soon in oxidizing atmosphere, and the surface of steel securely attachedly, thus effectively stop proceeding of oxidation; Two is at steel surface, forms the high-temperaure coatings such as dystectic oxide, carbide metal, nitride by various method.
The high temperature that nickel cobalt (alloy) ability is 1200 DEG C, can be used for the component of jet airplane and automotive gas turbine.The non magnetic heat resistant alloy of nickel ferro-cobalt still has the feature of high strength, good toughness 1200 DEG C time, can be used for the parts of space shuttle and the control arm etc. of atomic pile.Searching meet high temperature resistant, can long-play (10 000 more than h), withstanding corrosion, high strength etc. require alloy material, be still the direction studied from now on.Utilize alloy approach, except refractory Fe-base alloy, also can obtain Ni-based, molybdenum base, niobium base and tungsten based heat resistant alloy, they at high temperature have good mechanical characteristics and chemical inertness.Wherein nickel based alloy is optimum super heating resisting metal material, and in tissue, matrix is mischcrystal and the Ni3Al metallic compound of Ni-Cr-Co, and after treatment, its serviceability temperature can reach 1000 ~ 1100 DEG C.The invention provides a kind of explosion-proof hatch cover, there is withstanding corrosion, the advantage that nonmagnetic, intensity is high and explosion-proof.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
