Description
Oppfinnelsen vedrører en opphengsdel av støpestål for løfting av tunge stålbærekonstruksjoner og utformet med fra et grunnlegeme fremspringende pulleranordning med et i hvert fall delvist omløpende tauspor for et krantau. The invention relates to a suspension part made of cast steel for lifting heavy steel support structures and designed with a puller device protruding from a base body with an at least partially circumferential rope track for a crane rope.
For utvinning av olje fra havbunnen bygges det som kjent store plattformer i havet, hvorpå det settes tore stålbeholdere, såkalte containere. En slik container gjøres ferdig på land og klargjøres for den planlagte innsats (eksempelvis boring, elektrisitetsforsyning, rengjøring, vannoppberedning, mann-skapsunderbringelse) og kan ha en vekt opptil ca. 3000 tonn. For the extraction of oil from the seabed, as is well known, large platforms are built in the sea, on which large steel containers, so-called containers, are placed. Such a container is completed on land and prepared for the planned effort (for example drilling, electricity supply, cleaning, water preparation, crew accommodation) and can have a weight of up to approx. 3000 tonnes.
En slik container er som regel forsynt med fire eller seks festepunkter for kr.antauene. Such a container is usually equipped with four or six attachment points for the NOK anchors.
Disse festepunkter blir vanligvis utformet som rør som er inn-sveiset i en av plater sammensveiset bjelke eller bærer. Disse konstruksjoner er kompliserte i fremstilling, fremfor alt når det dreier seg om høyere containervekter. De har også ofte den ulempe at de er anordnet over containerdekket, hvor de etter plasseringen av containeren er i veien for ytterligere ut-bygging av plattformen og derfor må brennes av. These attachment points are usually designed as pipes that are welded into a beam or carrier welded together from plates. These constructions are complicated to manufacture, above all when it comes to higher container weights. They also often have the disadvantage that they are arranged above the container deck, where after the placement of the container they are in the way of further development of the platform and therefore have to be burned off.
Det har vært foreslått festepunkter utført som støpeståldeler, med tykke vegger, og med en pullerform tilpasset krantauet. Samtlige bygger på det prinsipp at det på begge sider av Attachment points have been proposed as cast steel parts, with thick walls, and with a bollard shape adapted to the crane rope. All are based on the principle that on both sides of
et kraftig bjelkelignende grunnlegeme skal rage ut en slik puller. Da pullerne er anordnet omtrent på midten av grunnlegemet og dette ved sine to ender er tilknyttet skjæringspunktene til container-bæreelementene, blir store bøyemomenter overført til containerstrukturen. a strong beam-like base body must project such a puller. As the bollards are arranged approximately in the middle of the base body and this is connected at its two ends to the intersections of the container support elements, large bending moments are transferred to the container structure.
Hensikten med foreliggende oppfinnelse er å tilveiebringe The purpose of the present invention is to provide
en opphengsdel som er mindre komplisert og har en mer kompakt form enn de tidligere kjente og som for redusering av bøye-momentene kan anordnes i skjæringspunktene til stålcontainer-ens bærelementer. a suspension part which is less complicated and has a more compact shape than the previously known ones and which, in order to reduce the bending moments, can be arranged at the intersections of the steel container's supporting elements.
Ifølge oppfinnelsen oppnås dette ved at grunnlegemet for feste til stålbærekonstruksjonsdeler har sneglehusform, og ved at det ved dets innerside er anordnet en puller, ved hvis basis det er tilsluttet en i tauområdet over minst 90° utstrakt rotasjonsflate med pulleraksen som dreieakse og med en kurve som generatrise, idet rotasjonsflaten strekker seg tangensielt fra basisen ut fra tausporet og i sitt fremre område har en åpning for opptak av krantauet. According to the invention, this is achieved by the fact that the basic body for attachment to steel supporting construction parts has a snail shell shape, and that a puller is arranged on its inner side, at the base of which a rotational surface extending over at least 90° in the rope area is connected with the puller axis as the axis of rotation and with a curve that generatris, in that the rotation surface extends tangentially from the base out from the rope track and in its front area has an opening for receiving the crane rope.
På denne måten oppnås en innsparing av en av de ellers vanlige to pullere, og den ene puller kan anordnes i et sneglehuslignende grunnlegeme som i hovedsaken er anordnet sentralt i skjær-ingspunktet mellom tilgrensende staver eller vegger i stålbære-konstruks j onen . In this way, a saving of one of the otherwise usual two bollards is achieved, and one bollard can be arranged in a snail shell-like basic body which is mainly arranged centrally at the point of intersection between adjacent rods or walls in the steel bearing construction.
Den nye opphengsdel er så kompakt at den kan oppta de store belastningene fra taukraften og fra stålbærekonstruksjonen. Samtidig er delen fordelaktig utført slik at den muliggjør The new suspension part is so compact that it can absorb the large loads from the rope force and from the steel support structure. At the same time, the part is advantageously designed so that it enables
en gunstig legging av krantauet rundt pulleren. a favorable laying of the crane rope around the bollard.
Ifølge oppfinnelsen kan fordelaktig åpningen være omtrent 1,1 til 3 ganger tausporets bredde. Derved, og som følge av utform-ingen av innerflaten, kan man få en nesten automatisk frigjør-ing av ståltauet etter at stålbærekonstruksjonen er satt på plass, slik at man derved eksempelvis kan innspare dyr kran-skipstid. According to the invention, the opening can advantageously be approximately 1.1 to 3 times the width of the rope track. Thereby, and as a result of the design of the inner surface, an almost automatic release of the steel rope can be obtained after the steel support structure has been put in place, so that, for example, expensive crane ship time can be saved.
På de mot stålbærekonstruksjonen vendte sider av grunnlegemet kan profiler eller plater av en hver art påsveises direkte. Hensiktsmessig kan det imidlertid på grunnlegemet være støpt tilslutningstverrsnitt for fastsveising av stålbærekonstruksjonsdelene. On the sides of the base body facing the steel support structure, profiles or plates of any kind can be welded on directly. Appropriately, however, the base body can have a cast connection cross-section for welding the steel support structure parts.
Pulleraksene kan være skråstilt i forhold til horisontalen, The bollard axes can be inclined in relation to the horizontal,
alt etter hvordan opphengsdelen sveises inn i stålbærekon-struks jonen . depending on how the suspension part is welded into the steel support structure.
Oppfinnelsen skal forklares nærmere nedenfor under henvisning til tegningene, hvor: Fig. 1 viser et frontriss av en i et anslagspunkt antydet opphengsdel, The invention will be explained in more detail below with reference to the drawings, where: Fig. 1 shows a front view of a suspension part indicated in an impact point,
fig. 2 viser et snitt etter linjen II-II i fig. 1, fig. 2 shows a section along the line II-II in fig. 1,
fig. 3 viser et snitt etter linjen III-III i fig. 1, og fig. 4 viser et snitt gjennom en utførelsesform med en puller-akse som er skråstilt i forhold til horisontalen. fig. 3 shows a section along the line III-III in fig. 1, and fig. 4 shows a section through an embodiment with a puller axis which is inclined relative to the horizontal.
Ved det sneglehusformede grunnlegemes 1 innerside er det anordnet en puller 2 med et tauspor 3. Fra basisen 4 strekker det seg over minst 90° en rotasjonsflate 5, med pulleraksen 6 som dreieakse og med en kurve 7 som generatrise. Rotasjonsflaten 5 går tangensielt ut fra tausporet 3 og har for opptak av krantauet 8 en åpning 9 som er dimensjonert tilsvarende omtrent 1,1 til 3 ganger bredden 10 i tausporet 3. Grunnlegemet er forsynt med støpte tilslutningstverrsnitt 11 for fastsveising til de med strekpunkterte linjer antydede bærekonstruksjonsdeler. A puller 2 with a rope track 3 is arranged on the inner side of the snail shell-shaped base body 1. From the base 4, a rotation surface 5 extends over at least 90°, with the puller axis 6 as the axis of rotation and with a curve 7 as the generatrix. The rotation surface 5 extends tangentially from the rope track 3 and has, for receiving the crane rope 8, an opening 9 which is dimensioned corresponding to approximately 1.1 to 3 times the width 10 in the rope track 3. The basic body is provided with molded connection cross-sections 11 for welding to those indicated by dotted lines supporting structure parts.
Ved utførelsesformen i fig. 3 er pulleraksen 6 anordnet hori-sontalt. Grunnlegemet 1 strekker seg til den med strekpunkterte linjer antydede overkant 12 i stålbærekonstruksjonen. In the embodiment in fig. 3, the puller axis 6 is arranged horizontally. The basic body 1 extends to the upper edge 12 of the steel support structure indicated by dotted lines.
Ved utførelsesformen i fig. 4 er pulleraksen 13 anordnet skråstilt i forhold til horisontalen, slik at det her ikke viste krantau kan anvendes uten en krantravers eller et kranåk som ellers anvendes for å holde og styre krantauene loddrett til festepunktene. In the embodiment in fig. 4, the bollard axis 13 is arranged inclined relative to the horizontal, so that the crane rope not shown here can be used without a crane traverse or a crane yoke which is otherwise used to hold and control the crane ropes vertically to the attachment points.
