Description
Denne oppfinnelse vedrører en fremgangsmåte for å øke vinsj - linestrekket utover en vinsj sin strekkraft. Nærmere bestemt dreier det seg om en fremgangsmåte hvor en hjelpeaktuator koples til vinsj linen mellom vinsjen og vinsj linens frie endeparti, hvoretter hjelpeaktuatoren strekker i vinsj linen sammen med vinsjen for sammen å kunne utøve en større strekkraft i vinsj linen enn det vinsjen alene kan utøve. Oppfinnelsen omfatter også en anordning for å kunne utøve oppfinnelsen. This invention relates to a method for increasing winch line tension beyond a winch's tensile force. More specifically, it concerns a method where an auxiliary actuator is connected to the winch line between the winch and the free end of the winch line, after which the auxiliary actuator stretches the winch line together with the winch in order to together exert a greater tensile force in the winch line than the winch alone can exert. The invention also includes a device to be able to practice the invention.
Med vinsj line menes i denne sammenheng enhver form for lang-strakt element som kan anvendes som lastbærende element og spoles opp på en vinsj. In this context, winch line means any form of elongated element that can be used as a load-bearing element and wound up on a winch.
Under arbeidsoperasjoner for eksempel til havs hvor det anvendes en vinsj som er montert på et fartøy, vil det fra tid til annen være behov for å kunne utøve et relativt stort strekk i vinsj linen. Dette forhold er velkjent ved drift av ankerhåndteringsfartøy hvor anker, som kan være relativt tunge, også må kunne trekkes løs fra havbunnen. During work operations, for example at sea where a winch mounted on a vessel is used, from time to time there will be a need to be able to exert a relatively large stretch in the winch line. This situation is well known in the operation of anchor handling vessels where anchors, which can be relatively heavy, must also be able to be pulled free from the seabed.
Arbeidsoperasjoner av den art som betinger et ekstra stort strekk i vinsj linen utgjør bare en liten del av et ankerhånd-teringsfartøys arbeidsoppgaver, men fartøyet må likevel være forsynt med en vinsj som er dimensjonert for disse relativt lite hyppige arbeidsoperasjoner. Work operations of the kind that require an extra large stretch in the winch line constitute only a small part of an anchor handling vessel's work tasks, but the vessel must still be equipped with a winch that is dimensioned for these relatively infrequent work operations.
Kostnadene som er forbundet med innkjøp og drift av vinsjen stiger betydelig når vinsjkraften må økes. En stor vinsj opp-tar også mer plass og er tyngre enn en mindre vinsj. The costs associated with the purchase and operation of the winch rise significantly when the winch power must be increased. A large winch also takes up more space and is heavier than a smaller winch.
Oppfinnelsen har til formål å avhjelpe ulempene ved kjent teknikk. The purpose of the invention is to remedy the disadvantages of known technology.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. The purpose is achieved according to the invention by the features indicated in the description below and in the subsequent patent claims.
Ved å forsyne et fartøy med en hjelpeaktuator som er innrettet til å kunne gripe tak om vinsj linen og å kunne trekke med en kraft som kan være i størrelsesoden den samme som vinsjens trekkraft, kan den totale trekkraft i vinsj linen økes betydelig når det er behov for dette. By providing a vessel with an auxiliary actuator which is designed to be able to grip the winch line and to be able to pull with a force that can be of the order of magnitude the same as the winch's pulling force, the total pulling force in the winch line can be increased significantly when needed for this.
Det er således mulig å forsyne for eksempel et ankerhåndte-ringsfartøy med en vinsj som har tilstrekkelig trekkraft til å løfte et anker, men ikke nok trekkraft til å løsne ankeret fra havbunnen. It is thus possible to provide, for example, an anchor handling vessel with a winch that has sufficient traction to lift an anchor, but not enough traction to detach the anchor from the seabed.
Under løsgjøring av for eksempel et anker koples hjelpeaktuatoren til vinsj linen, hvoretter vinsjen sammen med hjelpeaktuatoren utøver en trekkraft i vinsj linen som er tilstrekkelig til å løsne ankeret. Hjelpeaktuatoren frigjøres deretter fra vinsj linen, hvoretter vinsjen kan løfte ankeret. During the release of, for example, an anchor, the auxiliary actuator is connected to the winch line, after which the winch together with the auxiliary actuator exerts a pulling force in the winch line that is sufficient to release the anchor. The auxiliary actuator is then released from the winch line, after which the winch can lift the anchor.
Ved anvendelse av wire som vinsj line kan det by på vanskelig-heter å få kople aktuatoren til vinsj linen på en betryggende måte uten å skade vinsj linen. When using wire as a winch line, it can be difficult to connect the actuator to the winch line in a reassuring manner without damaging the winch line.
Ifølge oppfinnelsen klemmes wiren mellom to bakker i en wireklemme, hvorav den ene bakke er forskyvbar inn og ut fra wiren og forspennes ved hjelp av mot hverandre rullende urunde dreibare fortrinnsvis langstrakte legemer. According to the invention, the wire is clamped between two trays in a wire clamp, of which one tray is displaceable in and out of the wire and is biased by means of oppositely rolling unround rotatable preferably elongated bodies.
I en alternativ utførelsesform er wireklemmen forsynt med en kileformet bakke, hvor den kileformede bakke er innrettet til å kunne trekkes inn i wireklemmen når aktuatoren utøver en strekkraft mot wiren. In an alternative embodiment, the wire clamp is provided with a wedge-shaped hill, where the wedge-shaped hill is arranged to be able to be drawn into the wire clamp when the actuator exerts a tensile force against the wire.
I det etterfølgende beskrives et eksempel på en foretrukket fremgangsmåte og utførelsesform som er anskueliggjort på med-følgende tegninger, hvor: Fig. 1 viser et planriss av et fartøy som er forsynt med en vinsj og hvor det er anordnet en hjelpeaktuator; Fig. 2 viser i større målestokk et planriss av en wireklemme ifølge oppfinnelsen; Fig. 3 viser et sideriss av wireklemmen i fig. 2 i åpen stilling; Fig. 4 viser det samme som i fig. 3, men her er wireklemmen lukket; og Fig. 5 viser en alternativ utførelsesform hvor wireklemmen ifølge fig. 2 er forsynt med en kileformet bakke. In what follows, an example of a preferred method and embodiment is described which is visualized in the accompanying drawings, where: Fig. 1 shows a plan view of a vessel which is equipped with a winch and where an auxiliary actuator is arranged; Fig. 2 shows on a larger scale a plan view of a wire clamp according to the invention; Fig. 3 shows a side view of the wire clamp in fig. 2 in open position; Fig. 4 shows the same as in fig. 3, but here the wire clamp is closed; and Fig. 5 shows an alternative embodiment where the wire clamp according to fig. 2 is provided with a wedge-shaped hill.
På tegningene betegner henvisningstallet 1 et fartøy som er forsynt med en vinsj 2 og en hjelpeaktuator 4. En vinsj line 6 er delvis spolt opp på vinsjen 2 og forløper ut over fartøy-ets 1 akterparti 8. In the drawings, the reference number 1 denotes a vessel which is equipped with a winch 2 and an auxiliary actuator 4. A winch line 6 is partially wound up on the winch 2 and extends over the stern part 8 of the vessel 1.
Hjelpeaktuatoren 4 som omfatter to hydraulikksylindre 10, er forbundet til vinsjens 2 fundament 12. Hydraulikksylindrenes 10 stempelstenger 14 er koplet til en om vinsj linen 6 påkopl-bar wireklemme 16. The auxiliary actuator 4, which comprises two hydraulic cylinders 10, is connected to the foundation 12 of the winch 2. The piston rods 14 of the hydraulic cylinders 10 are connected to a wire clamp 16 that can be attached to the winch line 6.
Wireklemmen 16 omfatter en klemmekropp 20 som er leddbart forbundet til stempelstengene 14 ved hjelp av leddbolter 22, en fast bakke 24 og en klembakke 26. Klembakken 26 er innrettet til ved hjelp av to urunde legemer 28, 28' å klemme vinsj linen 6 mot den faste bakke 24. The wire clamp 16 comprises a clamping body 20 which is articulately connected to the piston rods 14 by means of joint bolts 22, a fixed tray 24 and a clamping tray 26. The clamping tray 26 is designed to clamp the winch line 6 against the fixed ground 24.
De urunde legemer 28, 28' forløper parallelt i en utsparing 3 0 i klemmekroppen 20 og er innrettet til å kunne dreies om sin lengdeakse mellom en uvirksom stilling hvor de urunde legemer 28, 28' ligger an mot hverandre ved sin mindre radius, og en virksom klemmende stilling hvor de urunde legemer 28, 28' ligger an mot hverandre langs sin større radius. The non-round bodies 28, 28' run parallel in a recess 30 in the clamping body 20 and are designed to be able to be rotated about their longitudinal axis between an inactive position where the non-round bodies 28, 28' rest against each other at their smaller radius, and a effective clamping position where the non-round bodies 28, 28' lie against each other along their larger radius.
Ved at de urunde legemer 28, 28' ruller og spenner mot hverandre og mot klemkroppen 20, respektive den forskyvbare klembakke 26, utøves en relativt stor klemkraft mot vinsj linen 6 når de urunde legemer 28, 28' er dreid til sin virksomme stilling og tildelt et rotasjonsmoment. By the fact that the non-round bodies 28, 28' roll and tension against each other and against the clamping body 20, respectively the displaceable clamping jaw 26, a relatively large clamping force is exerted against the winch line 6 when the non-round bodies 28, 28' are rotated to their effective position and allocated a rotational moment.
En dreieaktuator. 32 er leddbart koplet til de urunde legemer 28, 28' ved hjelp av hevarmer 34, 34' og er innrettet til å kunne dreie de urunde legemer 28, 28' om sine respektive lengdeakser. A rotary actuator. 32 is articulately connected to the non-round bodies 28, 28' by means of lever arms 34, 34' and is arranged to be able to rotate the non-round bodies 28, 28' about their respective longitudinal axes.
I en alternativ utførelsesform er wireklemmen 16 forsynt med en kileformet bakke 36 som erstatter den faste bakke 24, og hvor den kileformede bakke 36 er innrettet til å kunne trekkes innover i klemkroppen 20 av vinsj linen 6 når vinsj linen 6 under last søker å forskyve seg i wireklemmen 16 og wireklemmen 16 er i inngrep med vinsj linen 6. In an alternative embodiment, the wire clamp 16 is provided with a wedge-shaped ground 36 which replaces the fixed ground 24, and where the wedge-shaped ground 36 is designed to be able to be pulled inward into the clamp body 20 by the winch line 6 when the winch line 6 under load seeks to displace in the wire clamp 16 and the wire clamp 16 is engaged with the winch line 6.
