Abstract

Das Kernbohrwerkzeug (1) umfaßt ein an seinem oberen Ende mit einem Bohrrohrstrang (4) verbindbares rohrförmiges Außengehäuse (2), das an seinem unteren Ende mit einer Kernbohrkrone (5) verbindbar ist, und ein einen erbohrten Kern aufnehmendes Innenrohr (8), das den unteren Bestandteil einer in ihrem oberen Bereich an einer Anschlußstelle (7) im Außengehäuse (2) abgestüzten Inneneinheit bildet, das mittels einer Lagervorrichtung (9) gegenüber dem oberen Teil der Inneneinheit (6) frei drehbar gelagert ist und das mittels einer Einstellvorrichtung (11) axial relativ zum Außengehäuse (2) einstellbar ist. Die Einstellvorrichtung (11) umfaßt dabei ein Stellgewinde (15, 18) und ein Verriegelungselement (22) mit in Riegelnuten (19, 20) einrückbaren Riegelklauen (23, 24). Die Einstellvorrichtung (11) bildet eine gesonderte Zwischeneinheit, die im Bereich zwischen der Anschlußstelle (7) für die Inneneinheit (6) und der Lagervorrichtung (9) für das Innenrohr (8) in das Kernbohrwerkzeug (1) eingefügt ist und einen in das Außengehäuse (2) eingesetzten Außenteil (12) sowie einen in die Inneneinheit (6) eingefügten Innenteil (13) mit zylindrischem Stellgewinde (15, 18) aufweist.
