Abstract

Das Bohrwekzeug umfaßt ein rohrförmiges Außengehäuse (1), das über Anschlußmittel an seinem oberen Ende mit einem Bohrrohrstrang und an seinem unteren Ende mit einer Bohrkrone (2) verbindbar ist, eine Pilotbohreinheit (3), die mittels einer Fangvorrichtung (4) aus dem Außengehäuse (1) aufziehbar und in dieses absetzbar sowie in diesem während des Bohrbetriebs axial verschiebbar ist, und einen bohrspülungsbetriebenen Tieflochmotor (16). Die Pilotbohreinheit (3) ist in Längsführungen (18) relativ zu diesen unverdrehbar, jedoch axial verschiebbar innerhalb des Außengehäuses (1) abgestützt ist, weist vom Druck der Bohrspülung beaufschlagbare Reaktionsflächen (5) zur Erzeugung einer auf die Pilotbohreinheit (3) in Sohlenrichtung wirkenden axialen Vorschubkraft auf und hat einen drehbar vom Tieflochmotor (16) antreibbaren, seinerseits einen Drehbormeißel (10) tragenden Drehkörper. Dabei bildet das Außengehäuse (1) den Stator des als Turbine (16) ausgebildeten Tieflochmotors und ein rohrförmiges, im Außengehäuse (1) drehbar abgestütztes Innengehäuse (17) den Rotor der Turbine (16), und im Innengehäuse (17) sind die die Pilotbohreinheit im Betrieb abstützenden Längsführungen (18) vorgesehen. The drilling tool comprises a tubular outer housing (1) which via connection means at its upper end with a drill pipe string and is connectable at its lower end to a drill bit (2), one Pilot drilling unit (3), which by means of a safety device (4) from the Outer housing (1) can be pulled open and removed as well as in this is axially displaceable during the drilling operation, and one drilling fluid operated deep hole motor (16). The pilot drilling unit (3) is in longitudinal guides (18) non-rotatable relative to these, but axially is slidably supported within the outer housing (1), has from Pressure of the drilling fluid to act upon reaction surfaces (5) Generation of a on the pilot drilling unit (3) in the sole direction acting axial feed force and has a rotatable from Deep hole motor (16) drivable, in turn a rotary chisel (10) load-bearing rotating body. The outer housing (1) forms the stator of the designed as a turbine (16) deep hole motor and a tubular, in Outer housing (1) rotatably supported inner housing (17) the rotor of the Turbine (16), and in the inner housing (17) are the pilot drilling unit in the Operation supporting longitudinal guides (18) are provided.
