Abstract

Ein Bohrgerät umfaßt einen ein Werkzeug (36) in Drehung versetzenden Antriebsmotor (22) und einen das Werkzeug axial verschiebenden Vorschubmotor (14). Lastgeber (12, 18, 20, 24) erfassen neben der Werkzeug-Vorschubgeschwindigkeit (V) mindestens zwei der drei Parameter Werkzeug-Vorschubkraft (F), Werkzeug-Drehmoment (M) und Werkzeug-Drehzahl (U). Eine Auswerte- und Steuereinheit (70) wertet die oben genannten Parameter aus und steuert den Antriebsmotor (22) und den Vorschubmotor (14) über Steuereinheiten (38, 42) so an, daß die Werkzeug-Vorschubkraft (F) und die Werkzeug-Drehzahl (U) bzw. das Werkzeug-Drehmoment (M) Werte annehmen, bei denen die Werkzeug-Vorschubgeschwindigkeit (V) für eine bestimmte Bodenhärte (H) maximal ist.

A drilling device comprises a drive motor (22) which rotates a tool (36) and a feed motor (14) which axially displaces the tool. In addition to the tool feed speed (V), load sensors (12, 18, 20, 24) record at least two of the three parameters tool feed force (F), tool torque (M) and tool speed (U). An evaluation and control unit (70) evaluates the above parameters and controls the drive motor (22) and the feed motor (14) via control units (38, 42) so that the tool feed force (F) and the tool speed (U) or the tool torque (M) assume values at which the tool feed speed (V) is maximum for a certain soil hardness (H).
