Abstract

Die Erfindung betrifft ein Erdbohrgerät (10) zum Erstellen von Bohrungen. Das Erdbohrgerät weist einen Antriebskopf (18) auf, mit dem ein Bohrwerkzeug (24) drehbar antreibbar ist. Am Bohrwerkzeug ist mindestens eine hydraulisch betätigbare Stelleinrichtung (28) zum Verstellen bewegbarer Werkzeugkomponenten (26) des Bohrwerkzeuges vorgesehen. Zum Bereitstellen des Stelldrucks für die Stelleinrichtungen ist eine Druckversorgung (38) vorgesehen, wobei der Stelldruck durch eine zwischen dem Antriebskopf und dem drehbaren Bohrwerkzeug vorgesehene Drehdurchführung (32) an die Stelleinrichtung des drehbaren Bohrwerkzeuges übertragbar ist. Die Übertragung des Stelldrucks erfolgt mit Hilfe eines umweltverträglichen Fluides durch die Drehdurchführung, wobei der Stelldruck nach dem Durchströmen der Drehdurchführung mit Hilfe mindestens eines Wandlers (40) in einen Hydraulikdruck für die hydraulische Stelleinrichtung umgewandelt wird.
