Abstract

Den foretrukne utførelse inkluderer fremgangsmåter og anordninger for lokalisering av et element inne i en åpning. En foretrukket anordning inkluderer generelt et hus som inneholder minst én roterbar innsatt ring, og en flerhet av strekkeelementer med en jevn innbyrdes avstand omkring ringens omkrets. Strekkelementene er forbundet til den roterende ring og huset, slik at rotasjon av ringen trekker strekkelementene stramme over innsiden av ringen. Rotering av ringen i den motsatte retning returnerer strekkelementene til deres opprinnelige orientering. Når strekkelementene er stramme, presser de elementer som passerer gjennom en åpning mot senteret. Når anordningen er installert i et boreringdekk, resulterer den i en enklere og mer effektiv rørsentreringsteknologi enn det som eksisterer i dag, hvilket gjør at rørstrenger kan sentreres i holdekilebushingen eller automatkilene, slik at holdekilene enkelt og sikkert kan installeres omkring rørstrengen.
