Claims (3)

  1. Schneidvorrichtung zum Herstellen eines Schlitzes neben einem eine Untergrundformation durchsetzenden Bohrloch, welche Vorrichtung einen Sägearm (15), der schwenkbar an einem Gehäuse (11) gelagert ist, so daß der Sägearm (15) zwischen einer ersten Stellung, in welcher der Sägearm (15) im wesentlichen parallel zu einer Längsachse (I) des Gehäuses (11) verläuft, und einer zweiten Stellung, in welcher der Sägearm (15) in einer Richtung weg von der Längsachse (I) des Gehäuses (11) verläuft, verschwenkbar ist, eine Endloskette (24), welche mit Schneidelementen (25) ausgestattet ist und den Sägearm (15) umgibt, und Antriebsmittel zum Bewirken einer Drehung der Kette (24) um den Sägearm (15) aufweist, dadurch gekennzeichnet, daß die Antriebsmittel einen Hydraulikmotor (25) aufweisen, der gleitend im Inneren des Gehäuses (11) angeordnet ist, so daß in Reaktion auf das Ausüben eines Hydraulikdruckes auf den Motor (27) der Motor entlang des Gehäuses (11) zusammen mit einem Schwenkmechanismus (17) verschoben wird, welcher dadurch den Sägearm (15) in die zweite Stellung schwenkt, und wobei die Vorrichtung weiters einen Federmechanismus (62, 64) aufweist, welcher den Sägearm (15) zurück in die erste Stellung schwenkt, wenn kein Hydraulikdruck am Motor (27) anliegt.
  2. Schneidvorrichtung nach Anspruch 1, bei welcher der Motor (27) ein hydraulischer Verdrängermotor ist, der im Gehäuse (11) im wesentlichen koaxial zur Längsachse (I) des Gehäuses angeordnet ist.
  3. Schneidvorrichtung nach Anspruch 1 oder 2, bei welcher der Schwenkmechanismus (17) ein Spornzahnrad (40) aufweist, das am abgestützten Ende des Sägearmes (15) befestigt ist, und eine Kolbenanordnung (35), welche den Motor (27) und eine Zahnstange (37) trägt, deren Zahnräder mit dem Spornzahnrad (40) zusammenwirken.
