Description
Oppfinnelsen angår en svingkran ifølge kravets innledning. The invention relates to a swing crane according to the preamble of the claim.
Ved de kjente vippekraner er det rep som kommerWith the well-known tilting cranes, there is trouble
fra lastreptrommelen ført over en venderull som ligger på samme akse som lastrepblokkens venderuller. Derved er ut-førelser kjent hvor selve lastvinsjen ligger i svingtårnet. Dette krever et svingtårn med en forholdsvis stor diameter. Det er også kjent å feste lastrepvinsjen på den side av svingtårnet som ligger motsatt utliggeren. Dette krever en stor påbygning på svingtårnet hvorved dettes påvirknings-radius forhøyes betydelig. Det er også kjent utførelser hvor lastrepvinsjen ikke er anordnet ved svingtårnets nedre ende, men ved dettes øvre ende og på samme akse som lastreprullene (Dubbel, Taschenbuch f vir den Maschinenbau, 13. opplag, 1970, s. 599) . from the load rope drum led over a turning roller that is on the same axis as the load rope block's turning rollers. Thereby, designs are known where the load winch itself is located in the swing tower. This requires a swing tower with a relatively large diameter. It is also known to fasten the loading pin on the side of the swing tower which is opposite the outrigger. This requires a large addition to the swing tower, whereby its radius of influence is increased significantly. There are also known designs where the load rope winch is not arranged at the lower end of the swing tower, but at its upper end and on the same axis as the load rope rollers (Dubbel, Taschenbuch f vir den Maschinenbau, 13th edition, 1970, p. 599).
Oppfinnelsen tar sikte på å utforme svingkranenThe invention aims to design the swing crane
slik at dens ytre konturer, minst så høyt som til vinsj-plattformen, holdes så små som mulig, slik at kranen ved svinging ikke støter mot eventuelle gjenstander i svingtårnets område. Dette gjelder særlig for svingkraner som er montert på skip. På denne skal det oppnås at svingkranenes ytre mål er så små som mulig slik at de ikke støter mot skipets overbygninger, containerstabler og lignende. so that its outer contours, at least as high as the winch platform, are kept as small as possible, so that when swinging the crane does not hit any objects in the area of the swing tower. This applies in particular to jib cranes mounted on ships. On this, it must be achieved that the external dimensions of the jib cranes are as small as possible so that they do not collide with the ship's superstructures, container stacks and the like.
Oppfinnelsen løser den stilte oppgave med den i kravets innledning beskrevne svingkran ved at løfterep-vinsjen er slik anordnet at utliggerbommen, når denne er bragt i vertikal henholdsvis tilnærmet vertikal stilling, The invention solves the task set with the jib crane described in the introduction of the claim in that the lifting rope winch is arranged in such a way that the jib boom, when it is brought into a vertical or nearly vertical position,
går fri av løfterepvinsjen og at de i svingtårnet festede lastrepruller er anordnet forskjøvet forover, i retning mot utliggerbommen. Dette betyr at venderullenes akse for last-repet ikke selv ligger koaksialt med venderullene for det lastrep som løper av fra vinsjen, henholdsvis ikke ligger koaksialt med lastvinsjens aksel. Byggeformen ifølge oppfinnelsen har fordelen av små ytre mål for svingkranens tverrsnitt. Svingkranen har kun behov for liten plass i sideretningen ved svinging. Derved har svingkranen ifølge oppfinnelsen, især ved bruk på skip, den fordel at den kan oppstilles i liten avstand fra skipets overbygninger, comes free from the lifting rope winch and that the load pulleys attached to the swing tower are arranged shifted forwards, in the direction of the outrigger boom. This means that the axis of the turning rollers for the load rope is not itself coaxial with the turning rollers for the load rope that runs off from the winch, or is not coaxial with the axis of the load winch. The construction form according to the invention has the advantage of small external dimensions for the crane's cross-section. The swing crane only needs a small amount of space in the lateral direction when swinging. Thereby, the jib crane according to the invention, especially when used on ships, has the advantage that it can be set up at a small distance from the ship's superstructures,
containerstabler eller lignende. Svingkranens plassbehov i horisontal retning er lavt. container stacks or similar. The jib crane's space requirement in the horizontal direction is low.
Ifølge en ytterligere utforming av oppfinnelse kan lastreprullene være anordnet symmetrisk til to ved svingtårnets øvre ende festede lasker, hvis avstand fra hverandre er så stor at den fortrinnsvis som enkeltbomut-ligger utformede utligger, fritt kan vippes inn i sin øvre endestilling mellom lastreprullene. Bruken av en enkelt-bomutligger er fordelaktig av flere grunner. En enkeltbom-utligger er lettere og kan fremstilles med færre sveisesøm-mer enn andre utliggere. Materialforbruket er mindre enn materialforbruket ved andre utliggere. Enkeltbomutliggeren kan være utformet som kassekonstruksjon slik at kasseformen tilspisses mot bommens spiss. According to a further design of the invention, the load rope reels can be arranged symmetrically to two lashings attached at the upper end of the swing tower, the distance from each other is so great that the outrigger, which is preferably designed as a single boom, can be freely tilted into its upper end position between the load rope reels. The use of a single boom outrigger is advantageous for several reasons. A single boom outrigger is lighter and can be produced with fewer welding seams than other outriggers. The material consumption is less than the material consumption of other outriggers. The single boom outrigger can be designed as a box structure so that the box shape tapers towards the tip of the boom.
Det er også mulig å utforme enkeltbomutliggere som rør. It is also possible to design single boom outriggers as tubes.
Ytterligere enkeltheter ved oppfinnelsen skal beskrives skjematisk i henhold til det på tegningen viste utførelseseksempel, hvor fig. 1 viser en svingkran i form av en vippekran for bruk på et skip, fig. 2 viser et grunn-riss av kranen på fig. 1, og fig. 3 viser den skjematiske repføring, delvis perspektivisk. Further details of the invention shall be described schematically according to the embodiment shown in the drawing, where fig. 1 shows a swing crane in the form of a tilting crane for use on a ship, fig. 2 shows a plan view of the crane in fig. 1, and fig. 3 shows the schematic rope routing, partly in perspective.
På det ikke viste skipsskrog er det montert en bæresøyle 1 som bærer et svingtårn 3 som er svingbart om en vippesikker kulesvingforbindelse 2. Til tårnets nedre ende er utliggeren 5 leddet i det horisontale lager 4. Midlene for å vippe utliggeren 5 er ikke inntegnet for ikke å for-styrre oversikten. Vippesystemet kan være utformet som sylindervippanordninger eller også som repvippanordninger. On the ship's hull, not shown, is mounted a support column 1 which carries a swing tower 3 which can be pivoted about a tilt-proof ball-swing connection 2. To the lower end of the tower, the outrigger 5 is linked in the horizontal bearing 4. The means for tilting the outrigger 5 are not drawn in because to disrupt the overview. The tilting system can be designed as cylinder tilting devices or also as rope tilting devices.
Kranutliggeren er på den ene side vist i arbeids-stillingen, betegnet med 5, og på den annen side i dens opprettstående stilling 5a. The crane jib is shown on the one hand in the working position, denoted by 5, and on the other hand in its upright position 5a.
Ved svingtårnets øvre ende bærer dette løfterep-vinsjen 6 som ligger fullstendig innenfor svingtårnets 3 ytre profil 7. Den rager hverken ut forover eller bakover fra svingtårnets ytre profil 7. At the swing tower's upper end, this carries the lifting rope winch 6, which lies completely within the swing tower's 3 outer profile 7. It projects neither forwards nor backwards from the swing tower's outer profile 7.
Fra løfterepvinsjen 6 løper løfterepet 8 over en venderull 9 ved utliggerens 5 fremre ende og derfra løper From the lifting rope winch 6, the lifting rope 8 runs over a turning roller 9 at the front end of the boom 5 and from there runs
løfterepet 8 i en blokk 10 tilbake til lastereprullene 11the lifting rope 8 in a block 10 back to the loading pulleys 11
som i forhold til løfterepvinsjen 6 er forsatt i retning mot utliggeren 5. Blokkens venderuller 12 ved utliggerens 5 spiss, er koaksialt anordnet med venderullen 9. Venderullene 9 og 12 er lagret i begge sider til utliggerens 5 spiss. which in relation to the lifting rope winch 6 is offset in the direction towards the jib 5. The block's turning rollers 12 at the tip of the jib 5 are arranged coaxially with the turning roller 9. The turning rollers 9 and 12 are stored on both sides of the tip of the jib 5.
Lastreprullene 11 er festet til svingetårnet 3The cargo rope reels 11 are attached to the swing tower 3
via lasker 13, idet avstanden mellom lastreprullene 11 er slik at den som bomutligger utformede utligger 5 i oppreist stilling 5a. er vippet inn mellom lastreprullene 11, hhv. laskene 13. via lasher 13, the distance between the load rope rollers 11 being such that the outrigger 5 designed as a boom outrigger is in an upright position 5a. is tilted in between the load rope rollers 11, respectively. lasken 13.
Løfterepet 8 bærer løfterepsrullen 14 for lastekroken med to strenger. The lifting rope 8 carries the lifting rope roll 14 for the load hook with two strings.
Slik det er vanlig ved vippesystemer, er.repførin-gen slik formet omkring festet for løfterepet 8, at lastekroken As is usual with tilting systems, the rope guide is so shaped around the attachment for the lifting rope 8, that the loading hook
■15 lastevei 17. forløper tilnærmet horisontalt ved vipping av utliggeren 5, som antydet i form av en stiplet sirkel-bue 16. ■15 loading path 17. runs approximately horizontally when tilting the outrigger 5, as indicated in the form of a dashed circular arc 16.
