| 282 | Überlagerungsbohrvorrichtung | EP87110824.7 | 1987-07-25 | EP0300080A1 | 1989-01-25 | Klemm, Günter, Dr.Ing. |
Die Überlagerungsbohrvorrichtung weist einen Drehantrieb (16), einen Vorschubantrieb (26) und einen Bohrhammer (18) auf, die auf das Bohrgestänge (10) einwirken. Die Antriebe (16,26,18) sind hydraulische Antriebe, von denen jeder durch eine separate Pumpe (27,27a,27b) versorgt wird. Die Pumpen sind leistungsgeregelte Pumpen, deren Fördervolumen sich innerhalb eines Regelbereichs druckabhängig derart verändert, daß die abgegebene Pumpenleist:ung bei variierenden Drücken im wesentlichen konstant bleibt. Dadurch wird erreicht, daß die Leistung der die Pumpen treibenden Motore (31,31a,31b) voll ausgenutzt wird. Bei hohem Bohrwiderstand nimmt der Pumpendruck zu, während das Fördervolumen sich verringert. Die Überlagerungsbohrvorrichtung arbeitet unter maximaler Ausnutzung der Motorleistungen mit dem jeweils höchsten Bohrvortrieb. |

| 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. | ||||||

| A rotary impact tool assembled in a drill string transfers torque and axial force between two components. The rotary impact tool includes an anvil and a hammer axially aligned with engaging faces. At a threshold torque, the hammer disengages from the anvil and rotates freely until a biasing element displaces the hammer to reengage the anvil. Kinetic energy stored in the hammer is transferred to the anvil when the faces of the hammer and anvil reengage. This provides an impact to the anvil and any attached component. The tool can accommodate misalignment of the attached components. | ||||||
