Description
Oppfinnelsen vedrører en dregg e.l. som angitt i hovedkravets ingress. The invention relates to a dredge etc. as stated in the preamble of the main claim.
Dregger med sammenleggbare dreggarmer er kjent, men dreggarmenes dreibare befestigelse i dreggstammen har forårsaket vanskeligheter såvel produksjonsteknisk som styrkemessig. I alminnelighet er både dreggstammen og dreggarmene forsynt med boringer, i hvilke en tapp inn-passes under monteringen og festes ved nagling eller en annen forholdsvis arbeidskrevende fremgangsmåte. Tappen har i alminnelighet vært av et annet materiale enn de øvrige dreggdeler, noe som i salt sjøvann har øket til-bøyeligheten for korrosjon ved elektrokjemisk reaksjon. Dessuten har det krevet betydelig ekstra arbeide å bore hullene og feste tappene, noe som i sin tur har øket dreggens produksjonsomkostninger. Dredges with foldable dredge arms are known, but the rotatable attachment of the dredge arms to the dredge stem has caused difficulties both in terms of production technology and strength. In general, both the draft stem and the draft arms are provided with bores, in which a pin is fitted during assembly and fixed by riveting or another relatively labor-intensive method. The pin has generally been made of a different material to the other dredge parts, which in salty seawater has increased the tendency for corrosion by electrochemical reaction. In addition, considerable extra work has been required to drill the holes and attach the pins, which in turn has increased the dregs' production costs.
Oppfinnelsens formål er å tilveiebringe en dregg The purpose of the invention is to provide a dredge
med sammenleggbare dreggarmer, hvor monteringen av dreggarmene kan skje på en mer fordelaktig måte enn ved fremstilling av kjente dregger. Oppfinnelsens kjennetegn fremgår av krav 1. Ifølge oppfinnelsen behøver hverken boring eller nagling å utføres i en dregg, da dreggarmens dreieaksel eller -tapp kan utgjøre en fast del av dregg-armen, og den åpning hvor denne aksel eller tapp monteres dannes ved å sammenføye to hensiktsmessig utformede deler. Ut fra et produksjonsmessig synspunkt er dette svært fordelaktig, da dreggdelene kan få sin endelige utformning på produksjonsstadiet, slik at ingen nevneverdig maskin-bearbeidning må utføres senere. with foldable drag arms, where the assembly of the drag arms can take place in a more advantageous way than when manufacturing known drags. The characteristics of the invention appear in claim 1. According to the invention, neither drilling nor riveting needs to be carried out in a drawbar, as the drawbar's pivot shaft or pin can form a fixed part of the drawbar arm, and the opening where this shaft or pin is mounted is formed by joining two appropriately designed parts. From a production point of view, this is very advantageous, as the mold parts can be given their final design at the production stage, so that no significant machine processing has to be carried out later.
Det er mest fordelaktig å utforme dreggarmenes lagringssteder slik at de delvis dannes av utspring på dreggstammen og delvis av et på dreggstammen montert tilleggsstykke. Her oppnås samtidig lageråpninger for alle dreggarmer ved hjelp av kun ett tilleggselement. Dette tilleggselement kan lett monteres på dreggstammen ved pressing eller sveising, hvorved en sikker og ikke demonter-bar sammenføyning oppnås. It is most advantageous to design the storage locations of the draw arms so that they are partly formed by protrusions on the draw stem and partly by an additional piece mounted on the draw stem. Here, bearing openings for all trailing arms are achieved at the same time with the help of just one additional element. This additional element can be easily mounted on the draft stem by pressing or welding, whereby a secure and non-detachable joint is achieved.
Ifølge oppfinnelsen kan en dregg lett fremstilles ved støpning. Fremstillingen skjer best ved at alle dreggdeler får sin endelige utformning allerede i støpnings-øyeblikket. Da kreves kun normal pussing av støpe-materialet og ingen presisjonskrevende bearbeidning. According to the invention, a dreg can be easily produced by casting. Production is best done by all mold parts getting their final design already at the moment of casting. Then only normal sanding of the casting material is required and no precision-demanding processing.
Det har vist seg at ifølge oppfinnelsen passer adusert støpejern svært godt for fremstilling av en dregg. En annen seig støpejernskvalitet, f.eks. seigjern, kan også anvendes med like godt resultat. It has been shown that, according to the invention, adused cast iron is very suitable for the production of a dreg. Another ductile cast iron grade, e.g. ductile iron, can also be used with equally good results.
Oppfinnelsen skal i det følgende beskrives nærmere under henvisning til vedføyede tegning, hvor The invention shall be described in more detail below with reference to the attached drawing, where
fig. 1 viser et sideriss av en dregg ifølge oppfinnelsen med utslåtte dreggarmer, og fig. 1 shows a side view of a dredge according to the invention with extended dredge arms, and
fig. 2 viser, delvis i snitt, en dregg ifølge oppfinnelsen med både sammenslåtte og utslåtte dreggarmer. fig. 2 shows, partially in section, a dredge according to the invention with both folded and extended dredge arms.
På tegningen angir 1 dreggstammen og 2 dreggens armer. Dreggarmene holdes i sammenlagt stilling ved hjelp av en fikseringsring 3, som også fungerer som holder for dreggarmene i utslått stilling. In the drawing, 1 indicates the dredge trunk and 2 the dredge's arms. The towing arms are held in the folded position by means of a fixing ring 3, which also functions as a holder for the towing arms in the extended position.
Av fig. 2 fremgår at dreggarmene 2 er forsynt med From fig. 2 shows that the draw arms 2 are provided with
en fast tapp 4 som helst bør være fremstilt som en fast del av dreggarmene. Tappene 4 lagres i en åpning 5 som dannes ved at et i dreggstammen 1 forekommende radialt utspring 6 danner åpningens øvre og indre kant, mens dens ytre og nedre kant dannes av et separat tilleggsstykke 7, som monteres nedenfra på dreggstammen. Dersom dreggen har fire armer, slik figuren viser, har dreggstammen 1 fire utspring 6 og tilleggsdelen 7 fire aksiale utspring 8. Herved dannes ved hver dreggarmtapp en passende lageråpning. Tilleggsstykket 7 er i den viste utførelses-form sveiset fast til dreggstammen 1 ved partiet 9. I stedet for å sveises fast, kan delen 7 også festes til dreggstammen 1 ved en passende pressoperasjon. a fixed pin 4 should ideally be produced as a fixed part of the draw arms. The pins 4 are stored in an opening 5 which is formed by a radial projection 6 occurring in the draft stem 1 forming the upper and inner edge of the opening, while its outer and lower edge is formed by a separate additional piece 7, which is mounted from below on the draft stem. If the dredge has four arms, as the figure shows, the dredge stem 1 has four protrusions 6 and the additional part 7 four axial protrusions 8. This creates a suitable bearing opening at each dredge arm pin. In the embodiment shown, the additional piece 7 is welded to the draft stem 1 at section 9. Instead of being welded, the part 7 can also be attached to the draft stem 1 by a suitable pressing operation.
Oppfinnelsen begrenser seg ikke til det viste utførelseseksempel, idet en flerhet av varianter og modi-fikasjoner er tenkelige innenfor rammen av de etter-følgende krav. The invention is not limited to the embodiment shown, as a plurality of variants and modifications are conceivable within the scope of the following claims.
