Abstract

Et tilbaketrekkbart borekronesystem (10) omfatter et driv- stykke (18) som er innrettet til å koples til en nedre ende av et bor (12), et verktøy (20) for installering og tilbake- trekking av borekronesegmenter (22) fra drivstykket (18) , og et innsatsstykke (24) for selektiv låsing av borekroneseg- mentene (22) til en ende av drivstykket (18) og frigjøring av borekronesegmentene (22). Et antall fordypninger (58) er utformet rundt en indre omkretsvegg ved den ene ende av drivstykket (18) , og et forankringssete (32) er utformet rundt innerveggen oppstrøms relativt fordypningene (58). Innerveggens område mellom forankringssetet (32) og fordyp- ningene (58) er profilert med en rekke koniske og rette flater. Verktøyet (20) innbefatter en glidbar vugge (176) som : strekker seg fra den ene ende omkring hvilken borekroneseg- i mentene (22) er fastholdt under installering og gjenerverv- else. Borekronesegmentene (22) holdes på plass rundt vuggen (176) med et elastisk bånd (198). Innsatsstykket (24) er ved den ene ende forsynt med en rekke kilespor (218) som er plas- sert over borekronesegmentene (22) når disse er låst til drivstykket (18). Innsatsstykket (24) er alltid fastholdt inne i drivstykket (18) . Borekronesegmentene (22) forflyttes ved hjelp av verktøyet (20) til drivstykket (18) og låses på plass ved hjelp av innsatstykket (24). Verktøyet (20) kan deretter trekkes tilbake, og boret (12) drives på vanlig måte. For å gjenerverve borekronesegmentene (22), senkes verktøyet (20) igjen ned i boret (12) og trekkes deretter tilbake et kort stykke for å trekke tilbake innsatsstykket (24) slik at borekronesegmentene (22) klapper sammen igjen på ', vuggen (176) og deretter kan trekkes tilbake fra boret (12).
