Description

Anordning til å stuve lastelukedekke sammensatt av i siksak sammenhengslede seksjoner utenfor den egentlige lasteromsåpning. Device for stowing cargo hatch cover composed of zigzag connected sections outside the actual cargo compartment opening.

For å dekke åpningen i lasterommene To cover the opening in the holds

på fartøyer kan man benytte mange forskjellige slags lukedekketyper. Ved en type on vessels, many different hatch cover types can be used. By a type

som er meget almindelig, består dekket av which is very common, the tire consists of

et fåtall, vanligvis to, seksjoner som er a few, usually two, sections that are

leddforbundet innbyrdes, og hvorav den the joint federation among themselves, and of which it

ene dessuten er leddforbundet med karmen. Denne dekktype lider imidlertid av one, moreover, is the hinged connection with the frame. However, this tire type suffers from

den ulempe at de forholdsvis store seksjoner stenger for utsikten fra eventuelle the disadvantage that the relatively large sections block the view from any

plattformer eller dekkhustak som befin-ner seg ved enden av lasteromsåpningen, platforms or deck house roofs located at the end of the hold opening,

og hvor vinsjer eller kraner er anbragt. and where winches or cranes are located.

Særlig på stykk-godsfartøyer er dette meget generende ved lasting og lossing, og Especially on general cargo vessels, this is very troublesome during loading and unloading, and

man benytter derfor ofte lastelukkedekker cargo hatch covers are therefore often used

som består av en flerhet av seksjoner med which consists of a plurality of sections with

forholdsvis liten utstrekning i lukens lang-skibsretning. relatively small extent in the long-ship direction of the hatch.

Den foreliggende oppfinnelse angår en The present invention relates to a

anordning til utenfor den egentlige lasteromsåpning å stuve et lasteromslukedekke device for stowing a cargo hatch cover outside the actual cargo hold opening

av den sistnevnte type og nærmere bestemt of the latter type and more specifically

et slikt som består av flere seksjoner som one that consists of several sections such as

alle mangler leddforbindelse med og er all lack joint connection with and are

forskyvbare på karmen, og som ved sine movable on the frame, and as by theirs

langskibsliggende tverrkanter er forsynt Longitudinal transverse edges are provided

med føringsorganer, hensiktsmessig hjul, with guide means, suitable wheel,

valser eller lignende, som samvirker med rollers or similar, which interact with

baner anordnet langs langskibskarmsidene, lanes arranged along the longitudinal ship frame sides,

og hvor seksjonene, når lukeåpningen frilegges, holdes i vertikal stilling på deler and where the sections, when the hatch opening is exposed, are held in a vertical position on parts

som over oppstuvningsstedet utgjør forlengelser av de nevnte baner, og hvor seksjonenes tverrskibs lengdekanter er forbundet med hverandre ved hengsler, slik which above the place of stowage constitute extensions of the aforementioned lanes, and where the longitudinal edges of the transoms of the sections are connected to each other by hinges, as

at hele lukedekket kan foldes siksakformet sammen. that the entire hatch cover can be folded together in a zigzag shape.

Oppfinnelsen er hovedsakelig karakterisert ved at føringsorganene for hver seksjon med ulike nummer regnet fra oppstuvningsstedet, og som består av to par føringsorganer, er anbragt det ene nær den mot oppstuvningsstedet vendende lengdekant av seksjonen, mens det annet er anbragt lenger inne på seksjonen, fortrins-vis hinsides den med den nevnte kant parallelle tyngdepunktakse for seksjonen, samtidig som karmen i den del av luken som er beregnet til å dekkes av den seksjon som ligger nærmest oppstuvningsstedet, er utformet med helning nedover mot dekket. Ved at seksjonene er innbyrdes forbundet ved gangjern, kan man med enkle midler føre lukedekket til lukket resp. til åpen stilling og alltid være sikker på at hver seksjon uten spesielle forholdsregler kommer på sin tilsiktede plass. Gangjernfor-bindelsen mellom dem gir også muligheter for å skaffe en god tetning. Ved at alle seksjoner føres utenfor den egentlige lasteromsåpning, blir denne helt tilgjenge-lig for lastnings- og lossingsredskaper, og den ubetydelige utstrekning av seksjonene i lengderetningen gjør at de i oppreist stilling ikke kommer til å stenge for utsikten for det personell som passer lastnings- og lossings-redskapene. The invention is mainly characterized by the fact that the guide means for each section with different numbers counted from the stowage point, and which consist of two pairs of guide means, are placed one near the longitudinal edge of the section facing the place of stowage, while the other is placed further inside the section, preferably show beyond the center of gravity axis of the section parallel to the aforementioned edge, while the frame in the part of the hatch intended to be covered by the section closest to the stowage location is designed with a slope downwards towards the deck. As the sections are interconnected by handrails, the hatch deck can be brought to closed or to the open position and always be sure that each section arrives in its intended place without special precautions. The turnbuckle connection between them also provides opportunities to obtain a good seal. As all sections are led outside the actual hold opening, this becomes fully accessible for loading and unloading equipment, and the insignificant extent of the sections in the longitudinal direction means that in an upright position they will not block the view of the personnel who are handling the loading and the unloading tools.

Tegningen viser som eksempel skjema-tisk en anvendelse av oppfinnelsen ved lasteluken på et større fartøy. As an example, the drawing schematically shows an application of the invention at the cargo hatch on a larger vessel.

Fig. 1 er et sideriss av luken med seksjonene i stengt stilling. Fig. 2 viser det samme sett ovenfra. Fig. 3 viser et mellomstadium i stuv-ningsarbeidet, og Fig. 1 is a side view of the hatch with the sections in the closed position. Fig. 2 shows the same seen from above. Fig. 3 shows an intermediate stage in the stowing work, and

fig. 4 viser endelig luken i helt åpen stilling. fig. 4 finally shows the hatch in the fully open position.

Fartøyets dekk er betegnet med 1 og lukeåpningens omgivende karm med 2. Et stykke fra karmen er der et dekkhus 3, på hvilket der på kjent måte er anordnet vinsjer. Mellom dekkshuset 3 og karmen 2 er der et rom 4 som er tilstrekkelig stort til å oppta samtlige seksjoner når disse i forbindelse med åpningsbevegelsen er ført over i vertikal stilling. The vessel's deck is denoted by 1 and the surrounding frame of the hatch opening by 2. Some distance from the frame there is a deckhouse 3, on which winches are arranged in a known manner. Between the deck housing 3 and the frame 2 there is a space 4 which is sufficiently large to accommodate all the sections when these are brought into a vertical position in connection with the opening movement.

Lasteromsåpningen dekkes av åtte seksjoner 5—12, som således enkeltvis får en forholdsvis ubetydelig utstrekning i forhold til lengden av lasteromsåpningen. Disse seksjoner er innbyrdes forbundet ved hengsler 13 på en slik måte at hverannen seksjon vil bli foldet med undersiden og hverannen med oversiden mot den fore-gående. Seksjonene er forsynt med tet-ningsanordninger av en eller annen i og for seg kjent art, som ikke vil bli beskre-vet nærmere, såvel ved de mellomliggende fuger som mellom seksjonene og karmen og er selvsagt utstyrt med hensiktsmessige organer for skalking. Inntil fugene mellom de forskjellige seksjoner er der anordnet hjul 14, bestemt til å løpe på en bane 15 som går langs karmen under lukedekkets åpningsbevegelse. Den ytterste seksjon 12 er dessuten på sin ytterkant forsynt med et par hjul 21, som løper på særskilte baner 22 anordnet utenfor banene 15 for de øvrige løpehjul. Banene 22 er dessuten forhøyet over planet for banene 15, hvorved banene 22 vil danne sidestyring for hjulene 14 når disse forskyves til og fra stuvningsstilling. Løpehjulene, resp. de deler av banene som ligger rett ut for hjulene når luken står i stengt stilling, kan på kjent måte være utformet slik at luke-seksj onene i den omtalte stilling kan brin-ges til å synke ned mot karmen og å løftes opp fra denne når en bevegelse henholdsvis avsluttes og påbegynnes. The hold opening is covered by eight sections 5-12, which thus individually have a relatively insignificant extent in relation to the length of the hold opening. These sections are interconnected by hinges 13 in such a way that every other section will be folded with the underside and every other with the upper side against the previous one. The sections are provided with sealing devices of one or another type known in and of themselves, which will not be described in more detail, both at the intermediate joints and between the sections and the frame and are of course equipped with suitable bodies for scaling. Up to the joints between the different sections, wheels 14 are arranged, destined to run on a track 15 which runs along the frame during the hatch cover's opening movement. The outermost section 12 is also provided on its outer edge with a pair of wheels 21, which run on special tracks 22 arranged outside the tracks 15 for the other running wheels. The tracks 22 are also elevated above the plane of the tracks 15, whereby the tracks 22 will form lateral steering for the wheels 14 when these are moved to and from the stowed position. The running wheels, resp. the parts of the tracks that lie directly in front of the wheels when the hatch is in the closed position can be designed in a known manner so that the hatch sections in the mentioned position can be caused to sink down towards the frame and to be lifted up from this when a movement respectively ends and begins.

Hver seksjon 5, 7, 9 og 11 med ulike nummer regnet fra oppstillingsstedet 4 er hver med sine endekanter forsynt med to føringsorganer 16 resp. 17. Disse er par-vis anordnet symmetrisk i forhold til hverandre, og det første parti, altså det som er nærmest oppstillingsstedet 4, og som er montert på en arm som er så lang at hjulet når utenfor de normale bæreruller 14, er beregnet på å samvirke med en bane 181 som strekker seg fra enden av karmen frem mot dekkshuset 3. Denne bane er forsenket under karmens topplan og har rennefor-met tverrsnitt, slik at der fås øvre og nedre føringsflater for organet 16. På samme måte er føringsorganet 17 montert på ar-mer som igjen er noe lengere enn armene for føringsorganet 16, slik at vedkom-mende organer kommer til å samvirke med en annen bane 19, som ligger utenfor banen 18, og som dessuten i sin vesentlige del ligger høyere enn karmens topplan. Disse føringsruller er anbragt hinsides seksjonenes tyngdepunktakse som er parallell med oppstillingsstedet, hvorved seksjonen så snart den er ført over karmkanten, vil søke å reise seg til vertikal stilling. Stil-lingen av disse føringsorganer kan variere alt efter seksjonenes dybde i forhold til karmhøyden, og da organet 16 under alle forhold presser seksjonene rett ned, kan organet 17 eventuelt bli plassert i eller noe foran tyngdepunktaksen. Den øvre bane 19 er bestemt til å bære seksjonene, og den strekker seg helt frem til dekkshuset, mens banen 18, hvis hovedsakelige funksjon ligger i å danne føring for endene av seksjonene når disse reiser seg til vertikal stilling, ikke nødvendigvis behøver nå helt frem til dekkshuset. Man kan avslutte denne bane et stykke fra dette, slik at der i de tilfeller hvor luken er stengt, blir dannet en passasje under den øvre bane 19. Each section 5, 7, 9 and 11 with different numbers counted from the installation location 4 is each provided with its end edges with two guide members 16 resp. 17. These are arranged in pairs symmetrically in relation to each other, and the first part, i.e. the one closest to the installation location 4, and which is mounted on an arm that is so long that the wheel reaches outside the normal support rollers 14, is intended for to cooperate with a path 181 which extends from the end of the frame towards the tire housing 3. This path is recessed below the top plane of the frame and has a trough-shaped cross-section, so that upper and lower guide surfaces for the member 16 are obtained. In the same way, the guide member 17 mounted on arms which are again somewhat longer than the arms for the guide member 16, so that the relevant members will cooperate with another track 19, which lies outside the track 18, and which is also, in its essential part, higher than the top plane of the frame . These guide rollers are placed beyond the section's center of gravity axis which is parallel to the installation location, whereby the section will seek to rise to a vertical position as soon as it is guided over the frame edge. The position of these guide members can vary according to the depth of the sections in relation to the frame height, and since the member 16 under all conditions presses the sections straight down, the member 17 can possibly be placed in or somewhat in front of the center of gravity axis. The upper track 19 is intended to carry the sections, and it extends all the way to the deckhouse, while the track 18, whose main function is to provide a guide for the ends of the sections when they rise to a vertical position, need not necessarily reach all the way to the deckhouse. This lane can be terminated some distance from this, so that in cases where the hatch is closed, a passage is formed under the upper lane 19.

Seksjonene manøvreres ved hjelp av en wire 25, som tilsluttes en av de forhån-denværende vinsjer. I den stilling som er vist på fig. 1, altså med luken stengt, be-høver man for å få en åpningsbevegelse bare å utøve en trekkraft i pilens retning. Når lukedekket fra åpen stilling skal føres ut over åpningen, behøver man til venstre for luken å ha et fast mothold som wiren kan føres rundt, forsåvidt man ikke også på denne side av luken har vinsjer eller andre tilsvarende organer. Under stenge-bevegelsen løper lukedekket på vanlig måte på rullene 14. Umiddelbart idet bevegelsen blir påbegynt, blir lukens seksjoner som tidligere nevnt løftet så meget opp at til-pressingen opphører. En anordning til dette formål er f. eks. antydet ved 24 i forbindelse med den nedre føringsflate i banen 18. I denne finnes der ved den posisjon som tilsvarer stengt luke, en forsenkning hvori hjulet, i det valgte tilfelle førings-rullen 16 på den første seksjon 5, kan rulle ned og dermed tilveiebringe en til-pressing av pakningen. Tilsvarende forsenkninger utformes i banene for hjulene 14 og 21. Disse forsenkninger forskyves sidelengs i forhold til hverandre slik at The sections are maneuvered using a wire 25, which is connected to one of the existing winches. In the position shown in fig. 1, i.e. with the hatch closed, to get an opening movement, one only needs to exert a pulling force in the direction of the arrow. When the hatch deck from the open position is to be led out over the opening, you need to have a fixed counter-hold to the left of the hatch around which the wire can be guided, provided that you do not also have winches or other similar devices on this side of the hatch. During the closing movement, the hatch deck runs in the usual way on the rollers 14. Immediately when the movement is started, the sections of the hatch, as previously mentioned, are lifted up so much that the pressing ceases. A device for this purpose is e.g. indicated at 24 in connection with the lower guide surface in the track 18. In this, at the position corresponding to the closed hatch, there is a recess in which the wheel, in the chosen case the guide roller 16 on the first section 5, can roll down and thus provide a pressing of the gasket. Corresponding recesses are designed in the tracks for the wheels 14 and 21. These recesses are shifted laterally in relation to each other so that

ingen hjul under sin passasje behøver å no wheels during its passage need to

komme i kontakt med forsenkninger bestemt for andre hjul, eller også kan for-senkningene utstyres med temporært inn-koblede utfyllende deler. Føringsorganet come into contact with depressions intended for other wheels, or the depressions can be equipped with temporarily connected supplementary parts. The governing body

16 føres derefter av banen 18 nedover, mens 16 is then guided by the path 18 downwards, while

føringsorganet 17, som løper på den ytre the guide member 17, which runs on the outer

bane 19, løfter seksjonens bortre del opp-over. Den påfølgende seksjon 6 følger med lane 19, lifts the far part of the section upwards. The subsequent section 6 follows

i bevegelsen og foldes med sin underside in the movement and folds with its underside

mot seksjonen 5, mens de øvrige seksjoner against section 5, while the other sections

bibeholder sin horisontale stilling og trekkes mot oppstillingsstedet. Så snart seksjonene 5 og 6 er ført utenfor lukeåpningen og har inntatt tilnærmelsesvis vertikal stilling, blir føringsorganet 16 ved seksjonen 7 oppfanget av banen 18 og bevegelsen gjentas nå med seksjonene 7 og maintains its horizontal position and is pulled towards the installation location. As soon as sections 5 and 6 have been guided outside the hatch opening and have assumed an approximately vertical position, the guide member 16 at section 7 is caught by the web 18 and the movement is now repeated with sections 7 and

8, mens de gjenværende seksjoner, stadig 8, while the remaining sections, constantly

i horisontal stilling, trekkes mot oppstillingsstedet. Dette gjentas til samtlige lu-ker er ført utenfor åpningen. Karmen kan in a horizontal position, is pulled towards the place of installation. This is repeated until all hatches have been moved outside the opening. Karmen can

Den siste seksjon 12 blir derfor stå-ende i en ikke helt vertikal stilling, slik at 21 at the outermost section, however, continues horizontally outwards to the end of the frame. The last section 12 is therefore left standing in a not quite vertical position, so that
