Description
Lukedeksel til handelsskip.Hatch cover for merchant ships.
Oppfinnelsen angår et lukedeksel for handelsskip, som er utformet som et lukket hullegeme. Det er kjent å ut-føre lukedeksler av denne art som en ponton, som kan benyttes som pram til transport av last mellom skipet, hvis dette ligger forankret et stykke fra.en havn, og en kai. Etter å være frigjort fra sin forbindelse med skipet, sjøsettes dekslet ved hjelp av skipets løfteinnretninger og benyttes deretter til lossing eller lasting, hvoretter det kan bukseres av en av skipets redningsbåter. The invention relates to a hatch cover for merchant ships, which is designed as a closed hollow body. It is known to design hatch covers of this kind as a pontoon, which can be used as a barge for the transport of cargo between the ship, if this is anchored some distance from a harbour, and a quay. After being released from its connection with the ship, the cover is launched using the ship's lifting devices and is then used for unloading or loading, after which it can be hoisted by one of the ship's lifeboats.
Foreliggende oppfinnelse består i at lukedekselet er forsynt med minst en sperrbar åpning for fylling av dets inn-vendige hulrom .med væske. The present invention consists in the hatch cover being provided with at least one lockable opening for filling its internal cavity with liquid.
Ved den forskrevne utforming av det hule lukedeksel som tank til opptagelse av en for skipets fart nød-vendig væskemengde, oppnås at man på andre steder i skipet får frigjort et tilsvarende volum, slik at det for nyttelast disponible volum økes i samme utstrekning. Lukedekselet kan f.eks. utnyttes som ballasttanker, hvilket har ytterligere den fordel at det høytliggende tyngdepunkt på ballastvannet i kammeret gjør skipet mindre stivt,- dvs. ' at det reiser seg langsommere etter å være krenget.over. Alternativt kan luke-dekselets hulrom være utformet til å benyttes som ferskvanns-eller brenseloljetank med mulighet for tilkopling til skipets ledningssystem-.<1>By the prescribed design of the hollow hatch cover as a tank for the absorption of a quantity of liquid necessary for the ship's movement, it is achieved that a corresponding volume is released elsewhere in the ship, so that the volume available for payload is increased to the same extent. The hatch cover can e.g. are used as ballast tanks, which has the further advantage that the high center of gravity of the ballast water in the chamber makes the ship less rigid, i.e. that it rises more slowly after being heeled over. Alternatively, the hatch cover's cavity can be designed to be used as a fresh water or fuel oil tank with the possibility of connection to the ship's wiring system-.<1>
Når lukedekselet er demonterbart med henblikk på å settes på vann ved lossing og lasting, kan det ha midler ved hjelp av hvilke det kan fortøyes.til skipet. Hvis dekselet ikke som ovenfor beskrevet skal anvendes som transportpram, men bare settes på vann for å' forbedre lukeåpningens til- gjengelighet, sikrer man seg på denne måte mot at dekselet går tapt under lossing og/eller lasting. When the hatch cover is removable for the purpose of being placed on water during unloading and loading, it may have means by which it can be moored to the ship. If, as described above, the cover is not to be used as a transport barge, but is only placed on water to improve the accessibility of the hatch opening, this ensures that the cover is not lost during unloading and/or loading.
Oppfinnelsen skal i det følgende forklares nærmere The invention will be explained in more detail below
under henvisning til den skjematiske tegning, derwith reference to the schematic drawing, there
fig. 1 viser et vertikalt snitt gjennom et skip med fig. 1 shows a vertical section through a ship with
lukedeksler ifø-lge oppfinnelsen, og!-hatch covers according to the invention, and!-
fig. 2 er et planriss av skipet sett ovenfra.fig. 2 is a plan view of the ship seen from above.
Det på tegningen viste skip har fire lasterom, som regnet forfra er betegnet med 1,2,3 og.I forbindelse med lasterommene I og 2 er det to mere konvensjonelle lukedeksler 5 og 6, som er innrettet til henholdsvis å svinges opp og foldes sammen langs den ene ende av lukekarmen for frigjørelse av lukeåpningen. Lasterommene 3 og ^ har hver to lukedeksler som er utført i overensstemmelse med oppfinnelsen, dvs. som lukkede hullegemer med en eller flere ikke viste åpninger med tilhørende ventiler, gjennom hvilke dekslenes indre, kan fylles og tømmes. The ship shown in the drawing has four cargo spaces, which are designated from the front as 1,2,3 and. In connection with cargo spaces I and 2, there are two more conventional hatch covers 5 and 6, which are designed to be swung up and folded respectively along one end of the hatch frame to release the hatch opening. The cargo spaces 3 and ^ each have two hatch covers which are made in accordance with the invention, i.e. as closed hollow bodies with one or more not shown openings with corresponding valves, through which the interior of the covers can be filled and emptied.
I den viste utførelsésform hører det til lasterommetIn the embodiment shown, it belongs to the cargo compartment
3 to innbyrdes like lukedeksler 7 som er utformet til å3 two identical hatch covers 7 which are designed to
løftes fra lukekarmen ved hjelp av skipets lasteinnretning, mens det til lasterommet H hører dels et av de nevnte luke-. deksler 7, dels et' likeledes hult lukedeksel 8 som imidlertid er hengslet forbundet med skipet ved sin akterkant, slik at det ved hjelp av den til luken hørende innretning kan svinges opp til loddrett stilling ved lukens akterkant, slik som an-tydet med prikkede linjer. is lifted from the hatch frame by means of the ship's loading device, while the cargo hold H also includes one of the mentioned hatches. covers 7, and a likewise hollow hatch cover 8 which is, however, hingedly connected to the ship at its stern edge, so that it can be swung up to a vertical position at the hatch's stern edge with the aid of the device belonging to the hatch, as indicated by dotted lines .
Som forklart ovenfor kan alle eller noen av de inn-vendige hulrom i lukedekslene 7 og 8 under skipets seilas i ballast være vannfylt, idet lukedekslene virker som ballasttanker, eller alternativt kan et eller flere av lukedekslene inneholde andre væsker, f.eks. ferskvann eller brenselolje. Hvis dekslene er.fylt med ballastvann■under seilasen til lastehavnen, tømmes de hensiktsmessig før de ved hjelp av laste-innretningen løftes opp og settes på vannet ved siden av skipet, slik at man unngår unødig store belastninger på løfteinnretningene. Når lukedekslene er satt på vannet og på hensiktsmessig måte fortøyd til skipet, er det uhindret adgang til lukeåpningene. Alternativt kan' de hule lukedekslene etter sjøsettingen, på den ovenfor beskrevne måte, benyttes til å transportere last mellom skipet og en kai, hvis skipet ligger forankret et stykke fra kaien. .1 den viste utførelsesforrri hvor lukedekselet 8 kan svinges opp til vertikal stilling, og derved frigjøre lukeåpningen helt, er det mulig å la dekslet bli stående i denne stilling under'lasting og lossing<!>selv om dekselet også alternativt kunne være utformet tii* å frigjøres fra sin hengselforbindelse med skipet og deretter benyttes som transportpram analogt med lukedekslene 7. As explained above, all or some of the internal cavities in the hatch covers 7 and 8 during the ship's sailing in ballast can be filled with water, as the hatch covers act as ballast tanks, or alternatively one or more of the hatch covers can contain other liquids, e.g. fresh water or fuel oil. If the covers are filled with ballast water during the voyage to the loading port, they are emptied appropriately before they are lifted up with the help of the loading device and placed on the water next to the ship, so as to avoid unnecessarily large loads on the lifting devices. When the hatch covers have been placed on the water and appropriately moored to the ship, there is unobstructed access to the hatch openings. Alternatively, the hollow hatch covers after launching, in the manner described above, can be used to transport cargo between the ship and a quay, if the ship is anchored some distance from the quay. .1 the embodiment shown where the hatch cover 8 can be swung up to a vertical position, thereby freeing the hatch opening completely, it is possible to leave the cover in this position during loading and unloading<!> although the cover could also alternatively be designed tii* to be released from its hinged connection with the ship and then used as a transport barge analogously to the hatch covers 7.
Det vil forstås at man etter omstendighetene kan ut-forme flere eller færre enn de fire viste lukedeksler som vasketanker ifølge oppfinnelsen. It will be understood that, depending on the circumstances, more or fewer than the four hatch covers shown can be designed as washing tanks according to the invention.
