Claims (8)

  1. Patentkrav
    En gripeanordning (21) tilpasset en anodestang (1) som er utformet med en åpning (9) mellom to ben (2, 3) ved sin øvre ende, og videre utformet med en boring I hvert ben, hvor en bolt (6) er fastmontert i bena og således utgjør et løftepunkt for anodestangen,
    karakterisert ved at
    gripeanordningen (21) har en overordnet rammestruktur (15, 15') utformet med to låseelementer (7, 8) svingbart anordnet i undersiøtteiser (9, 10) idet låseelementene (7, 8) tiliates å rotere fra en første fastholdt posisjon slik at det dannes et gap mellom disse når gripeanordningen (21) og den øvre enden av anodestangen (1) fønes sammen, idet låseelementene (7, 8), etter at bolten (6) har passert gapet, roteres tilbake til sin låste stilling ved å komme til anslag mot de avstøttende deler {T 8’) av understøttelsene (S, 10), hvorved gripeanordningen (21) låses til anodestangen (1).
  2. 2. En gripeanordning (21 ) i samsvar med krav 1 ,
    karakterisert ved at
    låseelementene (7, 8} er svingbart opplagret i understøttelsene (9, 10) ved hjelp av aksler.
  3. 3. En gripeanordning (21 ) i samsvar med krav 1 ,
    karakterisert ved at
    understøttelsene (9, 10) er anordnet for utadrettet lineær bevegelse i den overordnede rammestrukturen (15, 15’) til gripeanordningen, forfrikobling.
  4. 4. En gripeanordning (21 ) i samsvar med krav 1 ,
    karakterisert ved at
    den omfatter ledeskjørt (16, 16’) for å tilrettelegge anbringelse av gripeanordningen (21 ) på enden av anodestangen (1 ).
  5. 5. En fremgangsmåte for å betjene en gripeanordning (21) for en anodestang (1) utformet med en åpning (9) mellom to ben (2, 3) ved sin øvre ende, og utformet med en boring i hver flanke, idet en bolt (8) er fastmontert i bena og representerer et løflepunkt for anodestangen,
  6. karakterisert ved at
  7. gripeanordningen (21 ) og den øvre enden av anodestangen (1 ) posisjoneres relativt til hverandre, Idet nevnte deler bringes til å innbyrdes å nærme hverandre, idet bolten (6) passerer gjennom et midlertidig gap formet ved rotasjon av to låseelementer (7, 8) som hvert er svingbart opplageret i en avstøtielse (9, 10) idet, etter at bolten bar passert gapet, roteres låseelementene tilbake til en posisjon fiksert ved anslag (7' 8') i avstøttelsen (9, 10) og således lukker gapet og låser gripeanordningen til anodestangen.
  8. 8. En fremgangsmåte i samsvar med krav 5,
    karakterisert ved at
    anodestangen (1) kan løsgjøres fra gripeanordningen (21) ved å bevege minst en av avstøttelsene (9, 10) i en retning bort fra den andre, og således danne et gap mellom låseelementene (7, 8) og tillate at bolten (8) kan passere i en motsatt retning gjennom nevnte gap.
    7. En fremgangsmåte i samsvar med krav 5,
    karakterisert ved at
    avstøttelsene (9, 10) er anordnet for lineær bevegelse i den overordnede rammesirukturen (15, 15’), og kan beveges manuelt ved hjelp av håndtak (13, 14).
    8. En fremgangsmåte i samsvar med krav 7,
    karakterisert ved at
    avstøttelsene (9, 10) er anordnet for lineær bevegelse i den overordnede rammesirukturen (15, 15<’>), og kan beveges ved hjelp av én aktuaior via håndtak (13, 14) eller to aktuatorer, én for hver avstøtielse.
