Description

Foreliggende oppfinnelse vedrører en anordning ved rørkobling omfattende et rørstykke med en flens i det minste i den ene ende, et ringformet organ som er anordnet koaksialt med rør-stykket og er bevegelig i forhold til dette ved hjelp av hydrauliske midler, og minst to kloformede armer som er dreibart forbundet med det ringformede organ og som ved dettes bevegelse kan bringes til å fastholde en andre flens, en plate e.l. The present invention relates to a device for connecting pipes comprising a pipe piece with a flange at least at one end, an annular body which is arranged coaxially with the pipe piece and is movable in relation to this by means of hydraulic means, and at least two claw-shaped arms which is rotatably connected to the ring-shaped member and which, by its movement, can be brought to retain a second flange, a plate or the like.

mot rørstykkets flens.against the flange of the pipe.

Rørkoblinger av ovennevnte type brukes bl.a. ombord i tankskip for tilkobling av rør eller slanger for lossing og lasting av f.eks. hydrokarboner. Koblingen finner også sin anvendelse ved bøyelasting av olje hvor en slange forsynt med en flens i enden føres ombord i skipet og forbindes med skipets tanker via en ofte dreibart anordnet forbindelsesinnretning i skipets forparti. Pipe couplings of the above type are used i.a. on board tankers for connecting pipes or hoses for unloading and loading e.g. hydrocarbons. The coupling is also used in buoy loading of oil, where a hose fitted with a flange at the end is led aboard the ship and connected to the ship's tanks via an often rotatably arranged connecting device in the ship's forepart.

En kobling egnet for dette formål er f.eks. vist i norsk patent nr. 136 627. I denne kobling beveges det ringformede organ som de kloformede armer er festet til ved hjelp av to hydraul-sylindere symmetrisk anordnet om rørets akse. Ulempen ved dette system er at hydraulsylindrene meget vanskelig lar seg kjøre absolutt synkront, og dette vil lett føre til at det ringformede organ inntar en skjev stilling når det søkes beveget, med forkiling mellom dette og rørstykket som resultat. En ytterligere mangel ved den kjente kobling er at hydraulsylinderne for det ringformede organs bevegelse lett vil kunne skades når koblingen anvendes på et dreibart rørstykke i skipets baug hvor det vil bli utsatt for kjemiske og mekaniske påkjenninger fra sjøvann og bølger. Videre vil de hydrauliske trykkslanger som hver sylinder fordrer kreve plass og påpasselighet om de ikke skal skades. Dertil bidrar hydraulsylindrene i betydelig grad til koblingens vekt. A connection suitable for this purpose is e.g. shown in Norwegian patent no. 136 627. In this coupling, the ring-shaped member to which the claw-shaped arms are attached is moved by means of two hydraulic cylinders arranged symmetrically about the axis of the pipe. The disadvantage of this system is that it is very difficult for the hydraulic cylinders to run absolutely synchronously, and this will easily lead to the ring-shaped member taking a crooked position when it is sought to be moved, with wedging between it and the pipe piece as a result. A further shortcoming of the known coupling is that the hydraulic cylinders for the annular body's movement can easily be damaged when the coupling is used on a rotatable piece of pipe in the ship's bow where it will be exposed to chemical and mechanical stresses from seawater and waves. Furthermore, the hydraulic pressure hoses that each cylinder requires will require space and care if they are not to be damaged. In addition, the hydraulic cylinders contribute significantly to the coupling's weight.

Det er oppfinnelsens hensikt å tilveiebringe en rørkobling av den innledningsvis nevnte type som ikke er beheftet med ovennevnte mangler og ulemper. Dette oppnås ifølge oppfinnelsen ved at de hydrauliske midler omfatter minst ett hydraulisk trykkammer som er avgrenset av det ringformede organ og rør-stykket. Ytterligere fordelaktige trekk ved oppfinnelsen fremgår av underkravene. It is the purpose of the invention to provide a pipe connection of the type mentioned at the outset which is not affected by the above-mentioned shortcomings and disadvantages. This is achieved according to the invention by the hydraulic means comprising at least one hydraulic pressure chamber which is delimited by the ring-shaped member and the pipe piece. Further advantageous features of the invention appear from the subclaims.

Til bedre forståelse av oppfinnelsen skal den beskrives nærmere under henvisning til det utførelseseksempel på en rørkobling ifølge oppfinnelsen som er vist delvis gjennomskåret på tegningen, For a better understanding of the invention, it shall be described in more detail with reference to the design example of a pipe connection according to the invention which is shown in partial section in the drawing,

Rørkoblingens rørstykke er betegnet med 1. Det er i den ene ende forsynt med en fastboltet flens 2 som igjen er forsynt med en tetning 3 for på tettende måte å kunne forbindes med en flens på en lasteslange e.l. Også i sin andre ende er rørstykket 1 forsynt med en fastboltet flens 4. Denne er forsynt .med bolt-hull 5 for fastskruing til f.eks. ovennevnte forbindelsesinnretning. The pipe section of the pipe connection is designated 1. It is provided at one end with a bolted flange 2 which is in turn provided with a seal 3 in order to be able to be connected in a sealing manner with a flange on a loading hose or the like. Also at its other end, the pipe piece 1 is provided with a bolted flange 4. This is provided with a bolt hole 5 for screwing to e.g. above connection device.

Det ringformede organ 6 består av en ytre del 7 og en indre del 8. Den ytre del 7 består av et fremre parti 9 som har stort sett samme indre diameter som rørstykkets 1 ytre diameter, og et bakre parti 10 med noe større indre diameter enn det fremre parti. Den indre del 8 har samme innvendige diameter som det fremre parti 9 og stort sett samme ytre diameter som innerdia-meteren av det bakre parti 10. Den indre del 8 er innfestet i den ytre dels 7 bakre parti 10, f.eks. ved hjelp av gjenger, slik at det dannes en innvendig ringformet utsparing 11 i det ringformede organ 6. The ring-shaped body 6 consists of an outer part 7 and an inner part 8. The outer part 7 consists of a front part 9 which has roughly the same inner diameter as the outer diameter of the pipe piece 1, and a rear part 10 with a somewhat larger inner diameter than the front part. The inner part 8 has the same inner diameter as the front part 9 and largely the same outer diameter as the inner diameter of the rear part 10. The inner part 8 is fixed in the rear part 10 of the outer part 7, e.g. by means of threads, so that an internal annular recess 11 is formed in the annular body 6.

Rørstykket 1 er forsynt med et ringformet fremspring 12 som rager inn i utsparingen 11. Fremspringet 12 har nær samme ytre diameter som den indre diameter av det bakre parti 10 av den ytre del 7 av det ringformede organ 6. Tetninger vil vanligvis være anordnet mellom fremspringet 12 og det bakre parti 10 og mellom rørstykket 1 og det ringformede organs indre del 8 og ytre dels 7 fremre parti 9. Disse tetninger, som.vil være vel- kjente for fagmannen, er for oversiktens skyld ikke vist på tegningen. Tetningene bevirker imidlertid at det dannes et trykktett kammer på hver side av fremspringet 12. Ved til-førsel av hydrauliske trykkmedium via et ledningssystem 13 til det ene eller andre av disse kammere, vil det ringformede organ 6 kunne beveges i forhold til rørstykket 1. The pipe piece 1 is provided with an annular projection 12 which projects into the recess 11. The projection 12 has nearly the same outer diameter as the inner diameter of the rear part 10 of the outer part 7 of the annular member 6. Seals will usually be arranged between the projection 12 and the rear part 10 and between the pipe piece 1 and the annular body's inner part 8 and outer part 7 front part 9. These seals, which will be well known to the person skilled in the art, are not shown in the drawing for the sake of clarity. The seals, however, cause a pressure-tight chamber to be formed on each side of the projection 12. By supplying hydraulic pressure medium via a conduit system 13 to one or the other of these chambers, the annular body 6 will be able to be moved in relation to the pipe section 1.

Til det ringformede organ 6 er det dreibart forbundet et antall kloformede armer 14 som styres i føringer 15 festet, til flensen 2. Føringene bevirker at de kloformede armer 14 beveger seg mellom de stillinger som er vist med hhv. heltrukken og strek-prikket linje når det ringformede organ 6 beveges aksialt i forhold til rørstykket 1, f.eks. ved tilførsel av hydrauliske trykkmedium til et av kammerne i det ringformede organ. I A number of claw-shaped arms 14 are rotatably connected to the ring-shaped member 6, which are controlled in guides 15 attached to the flange 2. The guides cause the claw-shaped arms 14 to move between the positions shown with respectively solid and dash-dotted line when the ring-shaped member 6 is moved axially in relation to the pipe piece 1, e.g. by supplying hydraulic pressure medium to one of the chambers in the annular body. IN

denne sammenheng kan utsparingen 11 sies å utgjøre en sylinder mens fremspringet 12 utgjør et stempel i denne sylinder. in this context, the recess 11 can be said to form a cylinder while the projection 12 forms a piston in this cylinder.

Det vil således være klart at man ifølge oppfinnelsen har til-veiebragt en rørkobling som er meget kompakt og robust, hvor det ringformede organ ikke har noen mulighet til å forkile seg på rørstykket, hvor de hydrauliske glideflater ligger fullstendig beskyttet og hvor antall hydrauliske trykkledninger er holdt til et minimum. Innen rammen av de påfølgende krav kan oppfinnelsen varieres, f.eks. ved kun å la det være et hydraulisk trykkammer på høyre side av fremspringet 12 slik at hydraulisk kraft bare benyttes til å lukke rørkoblingen. I dette tilfelle kan koblingen tenkes åpnet ved hjelp av en fjær anordnet mellom det ringformede organs høyre endeflate og flensen 4. Videre kan utsparing og fremspring ha sirkelsektorform og stort sett samme bredde i rørstykkets aksiale retning slik at man ved hjelp av hydrauliske trykk kan bevirke rotasjon av det ringformede organ i forhold til rørstykket. It will thus be clear that, according to the invention, a pipe coupling has been provided which is very compact and robust, where the ring-shaped member has no possibility of wedging itself on the pipe piece, where the hydraulic sliding surfaces are completely protected and where the number of hydraulic pressure lines is kept to a minimum. Within the framework of the subsequent claims, the invention can be varied, e.g. by only leaving a hydraulic pressure chamber on the right side of the projection 12 so that hydraulic power is only used to close the pipe connection. In this case, the connection can be thought of as being opened with the help of a spring arranged between the ring-shaped member's right end face and the flange 4. Furthermore, recesses and protrusions can have the shape of a circular sector and largely the same width in the axial direction of the pipe so that rotation can be effected with the help of hydraulic pressure of the annular body in relation to the pipe section.
