RULLELOD TIL BUNDTRAWLINGROLLER LOT FOR BOTTRAWLING

Den foreliggende opfindelse angår et trawllod af rulletypen med styrende egenskaber i overensstemmelse med indledningen til det efterfølgende krav 1.The present invention relates to a roll type trawl with guiding characteristics according to the preamble of the following claim 1.

55

Rullelod benyttes i stor udstrækning ved bundtrawling med dobbelttrawl, idet sådanne lodder forbindes med de to trawlposers respektive mod hinanden vendende hjørner og med en trawlwire, som trækkes af en trawler. Ved de to trawlposers respektive yderhjørner er der anbragt trawldøre, som også er forbundet med en respektiv trawlwire, som igen 10 trækkes af trawleren. Trawldørene bevirker, at trawlposernes yderhjørner trækkes udefter således, at trawlposen bliver udspilet og derved får et stort areal ved åbningen. Et størst muligt åbningsareal er ønskeligt for at fange flest mulige fisk i forhold til den strækning, trawlet trækkes henover.Rollers are widely used in double trawl bottom trawling, with such trawls being connected to the respective trawl bags' opposite corners and to a trawl wire pulled by a trawler. At the respective outer corners of the two trawl bags, trawl doors are provided, which are also connected to a respective trawl wire, which in turn is pulled by the trawler. The trawl doors cause the outer corners of the trawl bags to be pulled out so that the trawl bag is played out, thereby giving a large area at the opening. A maximum possible opening area is desirable to catch as many fish as possible in relation to the distance the trawl is pulled over.

15 I NO 307541, der tilhører samme ansøger, er det beskrevet, hvordan tre (eller flere) trawl kan forbindes med hinanden side om side til et tripletrawl for derved at forøge det samlede åbningsareal yderligere i forhold til et dobbelttrawl. Der er i dette patent også beskrevet et styrende lod til at holde den midterste trawlpose udspilet, uden at dette medfører, at de yderste trawlposer klapper sammen.15 NO 307541, belonging to the same applicant, describes how three (or more) trawls can be joined side by side to a triplet trawl, thereby further increasing the total opening area relative to a double trawl. This patent also discloses a guide to keep the middle trawl bag spaced out without causing the outer trawl bags to collapse.

Den foreliggende opfindelse har til formål at videreudvikle loddet ifølge NO 307541 til et rullelod til bundtrawling. Dette tilvejebringes ved de træk, der er angivet i den kendetegnende del af krav 1.The present invention has for its object to further develop the solder of NO 307541 into a bottom trawl solder. This is provided by the features defined in the characterizing part of claim 1.

25 Opfindelsen vil nu blive nærmere forklaret under henvisning til et udførelseseksempel i de efterfølgende tegninger, hvor fig. 1a og 1b viser den nederste del af et lod ifølge den foreliggende opfindelse, henholdsvis set fra siden og ovenfra, og 30 fig. 2a og 2b viser et sammensat lod ifølge den foreliggende opfindelse, henholdsvis set fra siden og ovenfra.The invention will now be explained in more detail with reference to an exemplary embodiment in the following drawings, in which fig. 1a and 1b show the lower part of a solder according to the present invention, seen from the side and from above, respectively; Figures 2a and 2b show a composite plumbing according to the present invention, viewed from the side and from above, respectively.

DK 176373 B1 2 I fig. 1a og 1b er der vist den nederste del af et lod i overensstemmelse med den foreliggende opfindelse. Denne de! af loddet ligner et konventionelt rullelod bortset fra enkelte vigtige detaljer, som forklares nærmere nedenfor.DK 176373 B1 2 In fig. 1a and 1b, the lower part of a solder is shown in accordance with the present invention. This one! of the solder is similar to a conventional roller solder except for some important details, which are explained in more detail below.

5 Loddet omfatter en lodramme 1, som er sammensat af en første vange 2, en anden vange 3 og en sarg 4. Vangerne 2 og 3 er udstyret med en respektiv opadragende ribbe, henholdsvis 5 og 6, og en respektiv nedadragende ribbe 7 og 8 (ribben 7 er ikke synlig).The solder comprises a vertical frame 1 which is composed of a first vane 2, a second vane 3 and a jar 4. The vanes 2 and 3 are provided with a respective upwardly extending ribs 5 and 6, respectively, and a respective downwardly extending ribs 7 and 8. (rib 7 is not visible).

Sargen 4 er udstyret med en opadragende ribbe 9.The lattice 4 is provided with an upwardly extending rib 9.

10 Mellem vangerne 2 og 3 er der anbragt en rulle 10. Rullen 10 er lejret i et leje 11 i hver af de nedadragende ribber 7 og 8 (kun det ene leje 11 er synligt). Mellem de to opadragende ribber 5 og 6 strækker der sig et rør 12, som er indrettet til at afstive rammen 1. Under brug skal rullen 10 rulle langs bunden og bevirke, at loddet bevæger sig let i forhold til bunden.10 Between rollers 2 and 3, a roll 10. is provided. The roll 10 is housed in a bearing 11 in each of the downwardly extending ribs 7 and 8 (only one bearing 11 is visible). Between the two upwardly extending ribs 5 and 6 extends a tube 12 arranged to support the frame 1. In use, the roller 10 should roll along the bottom and cause the solder to move slightly with respect to the bottom.

15 I vangerne 2 og 3 er der på højde med røret 12 udformet et hul, henholdsvis 13 og 14.In the columns 2 and 3, at the height of the tube 12, a hole, 13 and 14 respectively, is formed.

Disse huller er indrettet til fastgørelse af en line, som strækker sig til et respektivt hjørne af to trawlposer. Ved sargen 4’s kant modsat rullen 10 er der udformet mindst ét hul 15 til fastgørelse af en trawlwire, som er forbundet med trawleren. På ydersiden af hver af de 20 opadragende ribber 5 og 6 er der anbragt et antal kontravægte 16 til afbalancering af lod det.These holes are arranged for attaching a line extending to a respective corner of two trawl bags. At the edge of the squeegee 4 opposite the roller 10, at least one hole 15 is provided for attaching a trawl wire connected to the trawler. On the outside of each of the 20 upwardly extending ribs 5 and 6, a plurality of counterweights 16 are provided for balancing it.

Så langt er loddet af konventionel type. I tillæg til dette er der ved den bageste ende og den forreste ende af hver af de opadragende ribber 5 og 6 anbragt en laske med et nøg-25 lehul 17, 18, 19 og 20. Desuden er der anbragt en laske med et nøglehul 21 midt på den opadragende ribbe 9. Endvidere er der på sargen 4 anbragt to korte opadragende ribber 22 og 23, som hver er udstyret med en låsetap 24 og 25, som fx kan være fjederbelastet.So far, the solder is of conventional type. In addition to this, at the rear end and the front end of each of the upwardly extending ribs 5 and 6, there is provided a keyhole 17, 18, 19, 19 and 20. A keyhole 21 key is provided. in the middle of the upwardly extending rib 9. Furthermore, two short upwardly extending ribs 22 and 23 are arranged on the lattice 4, each of which is provided with a locking pin 24 and 25, which may for example be spring loaded.

Der er desuden udformet en række huller 15 ved sargen 4's forreste kant. Trawlwiren kan så flyttes mellem forskellige huller 15 for at forøge eller reducere det styrende lods side-30 rettede trækkraft.In addition, a series of holes 15 are formed at the leading edge of the lattice 4. The trawl wire can then be moved between different holes 15 to increase or decrease the lateral directional traction of the guiding pilot.

I fig. 2a og 2b er der vist et komplet lod ifølge den foreliggende opfindelse. Den nederste del 30 svarer til det, der er vist i fig. 1a og 1b. Den øverste del 31 er en styredel, som omfatter en bundplade 32, en topplade 33 og et antal hovedsageligt lodrette finner 34.In FIG. 2a and 2b, a complete solder according to the present invention is shown. The lower portion 30 corresponds to that shown in FIG. 1a and 1b. The upper portion 31 is a guide portion comprising a base plate 32, a top plate 33 and a plurality of substantially vertical fins 34.

35 Ved den forreste ende er der en indløbsåbning 35 mellem hver finne, og ved den bageste DK 176373 B1 3 er der en udløbsåbning 36 mellem hver finne. Finnerne buer mod venstre (set i slæberetningen) fra indløbsåbningerne 35 til udløbsåbningerne 36. I bundpladen 32 er der udformet et antal åbninger 37.35 At the front end there is an inlet opening 35 between each fin, and at the rear DK 176373 B1 3 there is an outlet opening 36 between each fin. The fins arc to the left (seen in the towing direction) from the inlet openings 35 to the outlet openings 36. A plurality of openings 37 are formed in the base plate 32.

5 I bundpladen 32 er der også udformet to huller 38. På undersiden af bundpladen er der også anbragt et antal tappe 39 med hoved. Disse tappe er anbragt på en sådan måde, at de svarer til og passer ind i nøglehullerne 17-21 på den nederste del 30. Når den øverste del 31 sættes på den nederste del 30, føres tappene ind i den forreste del af nøglehullerne 17-21, som har størst diameter. Den øverste del føres så bagover således, at tappene 10 39 kommer ind i den bageste del, som har mindst diameter. Tappene 39’s hoved har større diameter end denne de! af nøglehullerne 17-21 således, at de ikke kan glide ud af nøglehullerne. Hullerne 38 flugter så med låsetappene 24 og 25, som føres ind i hullerne 38, og hindrer den øverste del 31 i at glide fremefter.5 In the base plate 32 two holes 38 are also formed. On the underside of the base plate a number of pins 39 are also arranged with head. These pins are arranged in such a way that they correspond to and fit into the keyholes 17-21 on the lower portion 30. When the upper portion 31 is inserted on the lower portion 30, the pins are inserted into the front portion of the keyholes 17- 21, which has the largest diameter. The upper part is then moved backwards so that the pins 10 39 enter the rear part which has the least diameter. The 39's pins have a larger diameter than this one! of the keyholes 17-21 so that they cannot slip out of the keyholes. The holes 38 then align with the locking pins 24 and 25 which are inserted into the holes 38, preventing the upper portion 31 from sliding forward.

15 I tillæg til den ovennævnte låsning vil den øverste del 31 blive presset bagover af vandstrømmen og derved yderligere blive hindret i at glide fremefter.In addition to the aforementioned locking, the upper portion 31 will be pushed backward by the flow of water and thereby further prevented from sliding forward.

Ved at udforme bundpladen 32 og toppladen 33 identiske kan en øverste del snos således, at ribberne 34 buer mod højre (set i slæberetningen). Således kan den øverste del 20 anbringes med den nederste plade eller den øverste plade 33 vendende mod den nederste del 30 for at opnå et lod, som styrer enten mod venstre eller mod højre. Dersom man ikke har brug for loddets styredel (fx ved trawling med dobbelttrawl), kan denne helt enkelt tages af.By forming the base plate 32 and the top plate 33 identical, an upper portion can be twisted so that the ribs 34 arc to the right (seen in the towing direction). Thus, the upper portion 20 may be disposed with the lower plate or upper plate 33 facing the lower portion 30 to obtain a plumb which guides either left or right. If you do not need the soldering guide part (for example with double trawling), it can simply be removed.

25 I stedet for at anbringe nøglehullerne 17-21 på den nederste del 30 og tappene 39 på den øverste del 31 kan disse selvsagt byttes om således, at nøglehullerne 17-21 er udformet på den øverste del 31 og tappene 39 på den nederste del 30. En kombination af tappe og nøglehuller på den øverste del 31 og tilsvarende huller og tappe på den nederste del 30 er også tænkelig. For nøglehuller 17-21 anbragt på den øverste del må nøglehullets 30 mindste diameter vende i slæberetningen således, at denne del omslutter tappene, når den øverste del 31 presses bagover.Of course, instead of placing the keyholes 17-21 on the lower portion 30 and the pins 39 on the upper portion 31, these may be exchanged so that the keyholes 17-21 are formed on the upper portion 31 and the pins 39 on the lower portion 30. A combination of pins and key holes on the upper portion 31 and corresponding holes and pins on the lower portion 30 are also conceivable. For keyholes 17-21 located on the upper portion, the smallest diameter of the keyhole 30 must be turned in the towing direction so that this portion encloses the pins when the upper portion 31 is pushed backward.

Det er også muligt at udforme den øverste del 31 todelt således, som det er antydet med linjen 38, så at der dannes en nederste sektion 31a og en øverste sektion 31b. Sektioner DK 176373 B1 4 ne 31a og 31b kan være forbundet med hinanden, fx ved boltforbindelser eller ved en låseforbindelse af den type, der forbinder den øverste del 31 med den nederste del 30.It is also possible to design the upper portion 31 two-fold as indicated by the line 38 so as to form a lower section 31a and a upper section 31b. Sections DK 176373 B1 4 ne 31a and 31b may be interconnected, for example by bolt connections or by a locking connection of the type connecting the upper part 31 to the lower part 30.

Ved at tage de to sektioner fra hinanden langs linen 38 og kun anbringe den ene af de to 5 sektioner 31a og 31b på den nederste del 30 kan man halvere den sideværts rettede trækkraft på loddet. Loddet kan derved tilpasses yderligere til trawlet, fartøjet, trawlerhastigheden og andre forhold.By taking the two sections apart along the line 38 and placing only one of the two sections 31a and 31b on the lower part 30, one can halve the laterally directed traction on the solder. The solder can thereby be further adapted to the trawl, vessel, trawler speed and other conditions.
