Description
Anordning ved fallrepstrapp. Device for fall rope stairs.
Oppfinnelsen vedrører en anordning ved fallrepstrapper. Oppfinnelsen har til hensikt å redusere den ulempe som gjør seg gjeldende når en fallrepstrapp anbringes så langt akterut på et fartøy at akterskipets krumning gjør at fallrepstrappens nedre del vil bli hengende fritt i luften. Dette forhold gjør seg gjeldende for tankfartøyer eller vanlige lastefartøyer hvor overbygnin-gene for de nyere typer kun er anordnet helt akterut. Fallrepstrappene vil da gjerne også være anordnet akterut. For å rette på det forhold at trappens nedre del under bruk vil bli hengende mer eller mindre fritt i luften på grunn av akterskipets krumning, har da fallrepet vært anordnet i alle tilfel-ler så langt frem på akterskipet at denne ulempe blir minst mulig. Derved får man imidlertid det problem at når fallrepet heises opp og svinges inn, vil dets forreste ende rage innover dekket og her være i vei-en. Særlig hvor dekket foran overbygnin-gene ligger lavere enn befestigelsesdekket for fallrepet vil denne ulempe være sjene-rende, da derved fallrepets forreste ende vil stikke fremover dekket på en meget uhel-dig måte. The invention relates to a device for rope ladders. The invention aims to reduce the inconvenience that occurs when a fall rope ladder is placed so far aft on a vessel that the curvature of the stern means that the lower part of the fall rope ladder will be hanging freely in the air. This situation applies to tankers or ordinary cargo vessels where the superstructures for the newer types are only arranged all the way aft. The fall rope stairs would also like to be arranged aft. In order to correct the fact that the lower part of the stairs will hang more or less freely in the air during use due to the curvature of the stern, the fall rope has in all cases been arranged so far forward on the stern that this inconvenience is minimized. Thereby, however, you get the problem that when the fall rope is raised and swung in, its front end will protrude into the tire and here be in the way. In particular, where the deck in front of the superstructures is lower than the fastening deck for the fall rope, this disadvantage will be embarrassing, as the front end of the fall rope will thereby protrude forwards of the deck in a very unfortunate way.
Oppfinnelsen elifinerer de nevnte ulem-per ved at fallrepets øvre plattform er gitt forskyvbar lagring langs dekket ved hjelp av en herfor tilpasset slede eller vogn som fortrinnsvis kan bevege seg i en for trappen anordnet stuingsresess. The invention eliminates the aforementioned disadvantages in that the fall rope's upper platform is provided with displaceable storage along the deck by means of a specially adapted sled or cart which can preferably move in a stowage recess arranged for the stairs.
Til bedre forståelse av oppfinnelsen skal denne forklares nærmere nedenfor under henvisning til et utførelseseksempel vist på tegningen. For a better understanding of the invention, it will be explained in more detail below with reference to an embodiment shown in the drawing.
Fig. 1 viser skjematisk en del av akter- Fig. 1 schematically shows part of the aft
skipet på et fartøy med nedfirt fallrepstrapp. the ship on a vessel with a lowered fall rope ladder.
Fig. 2—4 viser, i større målestokk, de-taljer vedrørende fallrepstrappen ifølge fig. 1. Fig. 2-4 show, on a larger scale, details regarding the fall rope ladder according to fig. 1.
Med 1 er betegnet akterskipet på et fartøy, på låringen av hvilket er anordnet en fallrepstrapp 2. Denne er på vanlig måte svingbart festet til en plattform 5, under-støttet ved en bøyle 7 hvis nedre ende hviler mot skipssiden, og som er opphengt ved en kjetting eller lignende 20 under plattformen. Trappens nedre ende 2' er på vanlig måte opphengt i en talje under en davit eller kranarm 6. 1 denotes the stern of a vessel, on the side of which a fall rope ladder 2 is arranged. a chain or similar 20 under the platform. The lower end of the stairs 2' is usually suspended from a hoist under a davit or crane arm 6.
Hvis plattformen 5 var stasjonært anbragt på det viste sted, ville fallrepets forreste ende 2' i oppheist og innsvinget stilling rage innover dekket foran partiet 4, If the platform 5 were stationary placed in the place shown, the front end 2' of the fall rope in the raised and swing-in position would protrude into the deck in front of the part 4,
slik man umiddelbart vil se av fig. 1. as will immediately be seen from fig. 1.
For å rette på dette er plattformen 5 ifølge oppfinnelsen gitt forskyvbar lagring langs skipssiden. To correct this, the platform 5 according to the invention is provided with displaceable storage along the ship's side.
Ifølge det viste eksempel skjer denne forskyvbare lagring ved at plattformen 5 er festet til en slede eller vogn 12, forsynt med ruller 13, 13, 14. Befestigelsen til denne vogn skjer ved de oppstående ører 9 med huller 15 for befestigelsesboltene. Vognen 12 beveger seg ned i en renneformet fø-ring, tilveiebragt ved at skipssiden 1 her er ført opp et stykke 10 over dekket 21. Plate-kledningen 3 bak resessen er likeledes forsynt med et horisontalt platestykke 11, som delvis overdekker den renneformede føring, slik tydelig fremgår av fig. 2 og 3. Vognen 12 har ruller 13, som ligger an mot dekket 21, og en støtterull 14 som ligger an mot undersiden av platen 11. Vognen 12 hind-res derved fra å kunne vippe ut fra førin-gen. Vognens 'rammeverk er fortrinnsvis utført med avrundede hjørner, slik som an-tydet i fig. 3, for å hindre at den kan kjøre seg fast i føringen. According to the example shown, this displaceable storage takes place by the platform 5 being attached to a sled or carriage 12, provided with rollers 13, 13, 14. The attachment to this carriage takes place at the upright ears 9 with holes 15 for the fastening bolts. The carriage 12 moves down in a channel-shaped guide, provided by the fact that the ship's side 1 is here brought up a piece 10 above the deck 21. The plate cladding 3 behind the recess is likewise provided with a horizontal plate piece 11, which partially covers the channel-shaped guide, as clearly appears from fig. 2 and 3. The carriage 12 has rollers 13, which rest against the tire 21, and a support roller 14 which rests against the underside of the plate 11. The carriage 12 is thereby prevented from tipping out from the guide. The carriage's framework is preferably made with rounded corners, as indicated in fig. 3, to prevent it from getting stuck in the guide.
Vognen 12 er videre forsynt med frem-spring eller lignende 16, for samvirke med stopperen 17. I det viste tilfelle består stopperen av et vinkeljern festet til plate-kledningen 3 på innsiden av føringen. Vognen og/eller føringen kan videre være forsynt med hensiktsmessige låseorgan for fastholdelse i ønskede stillinger. The carriage 12 is further provided with projections or the like 16, for cooperation with the stopper 17. In the case shown, the stopper consists of an angle iron attached to the plate cladding 3 on the inside of the guide. The carriage and/or the guide can also be provided with suitable locking means for retention in the desired positions.
Vognen kan bevege seg langs føringen ved den horisontale kraftkomponent som fåes ved avfiring resp. heising av fallrepet, hvorved den automatisk vil bevege seg forover til den på fig. 1 viste stilling når fallrepet fires av, og automatisk vil bevege seg akterover til anlegg mot en hensiktsmessig, ikke vist, stopper når fallrepet heises opp. Om nødvendig kan der være anordnet en spesiell, eventuelt en lett tilriggbar kran eller lignende 22, ved hjelp av hvilken for-flytningen av fallrepstrappen kan utføres. The carriage can move along the guide by the horizontal force component obtained by firing or lifting the fall rope, whereby it will automatically move forward to the one in fig. 1 shown position when the halyard is detached, and will automatically move aft to rest against an appropriate, not shown, stop when the halyard is raised. If necessary, a special, possibly easily accessible crane or similar 22 can be arranged, with the help of which the movement of the rope ladder can be carried out.
På grunn av plattformens 5 forflytt-barhet langs skipssiden, er det nødvendig at støttebøylen 7 i sin nedre ende utformes slik at den lett kan gli langs skipssiden. Fig. 4 viser et eksempel på hvorledes dette kan oppnåes. Bøylens 7 nedre ende er festet i et hus 8, som gir lagring for to hjul 18 som dreier seg om en vertikal akse 19. Ved plattformens 5 forflytning langs skipssiden vil således hjulene 18 rulle langs denne. Due to the mobility of the platform 5 along the ship's side, it is necessary that the support bracket 7 at its lower end is designed so that it can easily slide along the ship's side. Fig. 4 shows an example of how this can be achieved. The lower end of the hoop 7 is fixed in a housing 8, which provides storage for two wheels 18 which revolve around a vertical axis 19. When the platform 5 moves along the side of the ship, the wheels 18 will thus roll along this.
Ved den beskrevne anordning vil man forstå at fallrepstrappen 2 i bruksstilling kan føres så langt forover at den henger ned langs et parti av skipssiden som ikke har særlig krumning. Samtidig kan trappen, på grunn av befestigelsen til den forflyttbare plattform 5, i oppheist stilling fø-res så langs akterover at dens forreste ende With the device described, it will be understood that the fall rope ladder 2 in the position of use can be moved so far forward that it hangs down along a part of the ship's side which does not have a particular curvature. At the same time, due to the attachment to the movable platform 5, in the raised position, the staircase can be moved along the stern so that its front end
2' ikke rager forbi forkanten av oppbygnin-gen, og altså innover det forenfor liggende dekk. 2' does not project past the front edge of the structure, and thus into the deck lying in front.
Det vil umiddelbart forståes at det ut-førelseseksempel som er vist på fig. 2, 3 og 4 bare er ment til illustrasjon av oppfinnel-sestanken. Den forflyttbare plattform-understøttelse kan selvsagt gis en rekke modifiserte utformninger, uten derfor å fravike påstandenes ramme. It will immediately be understood that the design example shown in fig. 2, 3 and 4 are only intended to illustrate the inventive concept. The movable platform support can of course be given a number of modified designs, without therefore deviating from the scope of the claims.
