Abstract

Bei der vorliegenden Vorrichtung (1) wird der Schlüssel (21) zum Festhalten des Zweikants (12) einer Bohrstange (10) von einem Hydraulikzylinder (35) angetrieben, der an den Ausgang des Drehmotors (7) angeschlossen ist. Der Schlüs­ sel (21) wird mit geringer Kraft auf den Zweikant (12) aufgeschoben. Dadurch wird die Bohrstange (10) und damit der Drehmotor (7) blockiert: der Durchfluß des Hydraulikme­ diums wird unterbunden und der Schlüssel (21) verbleibt bis zum Ausüben einer separat eingeleiteten kräftigen Drehbe­ wegung zum Anlösen der Gewindeverbindung (11) zwischen der Muffe (15) und der Bohrstange (10) in seiner Lage.
Durch einen Druckspeicher (61) und Rückschlagventile (57, 62) bleibt der Druck im Hydraulikzylinder (35) bis zum separat eingeleiteten Zurückziehen des Schlüssels erhalten.
