Claims (8)

1. Klemmvorrichtung für Rundmaterial, insbesondere für Bohrgestänge mit
  • - zwei gegenläufig bewegbaren Klemmbackenhaltern (2),
  • - wenigstens jeweils einer parallelen, aus Zylinderabschnitten gebildeten, quer zur Bewegungsrichtung der Klemmbackenhalter (2) verlaufenden, in Bewegungsrichtung der Klemmbackenhalter (20) offenen Aufnahme (9) in jeweils einem Klemmbackenhalter (2) für in den Aufnahmen (9) winkelbeweglich angeordnete, als abgeflachte Zylinder ausgebildete Klemmbacken (10),
  • - wobei die Aufnahmen (9) und die Klemmbacken (10) so bemessen sind, daß die Klemmbacken (10) in Bewegungsrichtung der Klemmbackenhalter (2) in den Aufnahmen (9), ohne herausfallen zu können, gehalten sind, die Öffnungen (23) der Aufnahmen (9) jedoch einen Ausbau der Klemmbacken (10) zulassen, wenn diese um etwa 90° gegenüber der Arbeitsstellung gedreht sind.
1. Clamping device for round material, especially for drill rods with
  • - two oppositely movable jaw holders ( 2 ),
  • - At least one parallel, formed from cylinder sections, transverse to the direction of movement of the jaw holder ( 2 ), in the direction of movement of the jaw holder ( 20 ) open receptacle ( 9 ) in a jaw holder ( 2 ) for angularly arranged in the receptacles ( 9 ) as flattened cylinder-shaped clamping jaws ( 10 ),
  • - The receptacles ( 9 ) and the jaws ( 10 ) are dimensioned so that the jaws ( 10 ) in the direction of movement of the jaw holder ( 2 ) are held in the receptacles ( 9 ) without being able to fall out, the openings ( 23 ) of the receptacles ( 9 ), however, permit the jaws ( 10 ) to be removed when they are rotated by approximately 90 ° with respect to the working position.
2. Klemmvorrichtung nach Anspruch 1, bei der in dem Klemmbackenhalter (2) entriegelbare Sperrelemente (12) angeordnet sind, die das Drehen der Klemmbacken (10) um mehr als in ihrer Arbeitsstellung erforderlich, verhindern. 2. Clamping device according to claim 1, in which in the jaw holder ( 2 ) unlockable locking elements ( 12 ) are arranged, which prevent the rotation of the jaws ( 10 ) by more than required in their working position. 3. Klemmvorrichtung nach Anspruch 2, bei der ein Sperrelement (12) in jedem Klemmbackenhalter (2) in Form eines die Zylinderabschnitte der Klemmbacken (10) anschneidenden Sicherungsbolzens (12) angeordnet ist, der in ausreichende Winkelbewegungen zulassende Nuten (11) in den Klemmbacken (10) eingreift.3. Clamping device according to claim 2, wherein a locking element ( 12 ) in each jaw holder ( 2 ) in the form of a cylinder section of the jaws ( 10 ) intersecting locking bolt ( 12 ) is arranged, the grooves ( 11 ) allowing sufficient angular movement in the jaws ( 10 ) engages. 4. Klemmvorrichtung nach Anspruch 3, bei der der Sicherungsbolzen (12) zum Entriegelnder Klemmbacken (10) ausziehbar ist.4. Clamping device according to claim 3, in which the securing bolt ( 12 ) can be pulled out to unlock the clamping jaws ( 10 ). 5. Klemmvorrichtung nach Anspruch 3, bei der der Sicherungsbolzen (12) zum Entriegeln der Klemmbacken (10) drehbar und mit einer die Nuten (11) freigebenden Abflachung versehen ist.5. Clamping device according to claim 3, in which the securing bolt ( 12 ) for unlocking the clamping jaws ( 10 ) is rotatable and is provided with a flattening which frees the grooves ( 11 ). 6. Klemmvorrichtung nach einem der Ansprüche 1 bis 4, bei der die Klemmbacken (10) herausnehmbare, mit Klemmzähnen versehene Einsätze (14; 18) aufweisen.6. Clamping device according to one of claims 1 to 4, wherein the clamping jaws ( 10 ) have removable inserts ( 14 ; 18 ) provided with clamping teeth. 7. Klemmvorrichtung nach einem der Ansprüche 1 bis 6, bei der in eine Bohrung (5) des Klemmbackenhalters (2) ein Zapfen (4) an einer Hydraulik-Kolbenzylindereinheit (3) eingreift und die Bohrung (5) und der Zapfen (4) korrespondierende, umlaufende Nuten (6, 7) aufweisen, in die eine O-Ringschnur (8) eingelegt ist.7. Clamping device according to one of claims 1 to 6, in which engages in a bore ( 5 ) of the jaw holder ( 2 ) a pin ( 4 ) on a hydraulic piston-cylinder unit ( 3 ) and the bore ( 5 ) and the pin ( 4 ) have corresponding circumferential grooves ( 6 , 7 ) into which an O-ring cord ( 8 ) is inserted. 8. Klemmvorrichtung nach Anspruch 7, bei der parallele Bohrungen (21) tangential an die Nuten (6, 7) geführt sind, durch die sich die O-Ringschnurenden in die Nuten (6, 7) hinein und entgegengesetzt wieder herausführen lassen.8. Clamping device according to claim 7, in which parallel bores ( 21 ) are guided tangentially to the grooves ( 6 , 7 ), through which the O-ring cord ends can be guided into the grooves ( 6 , 7 ) and out again in opposite directions.
