Description

Drehtischantrieb Zusatz zum Patent 634 383 Die Erfindung betrifft eine weitere Ausgestaltung des Drehtischantriebes nach Patent 634383. Dieser Drehtischantrieb richtet sich darauf, daß ein Voreilen des Drehtisches einschließlich Bohrgestänge bei plötzlich losbrechendem Meißel möglich gemacht ist, ohne daß die hiermit verbundenen Gestängeschläge auf den Drehtischantrieb übertragen werden. Die aus diesem Grunde zwischen Antrieb und Gestänge eingebaute überholkupplung ermöglicht den Antrieb des Bohrgestänges jedoch nur in einem Drehsinn. Turntable drive addendum to patent 634 383 The invention relates to a further embodiment of the turntable drive according to patent 634383. This turntable drive is aimed at making it possible for the turntable including drill rods to advance if the chisel suddenly breaks away without the associated rod blows being transmitted to the turntable drive . For this reason, the overrunning clutch installed between the drive and the rods enables the drill rod to be driven in only one direction of rotation.

Um nun die Möglichkeit zu schaffen, den Drehtisch in umgekehrtem Sinne anzutreiben, z. B. bei Durchführung von Fangarbeiten, ohne auf die Voreilmöglichkeit gemäß dem Hauptpatent beim Bohrbetrieb verzichten zu müssen, wird die Anordnung einer besonderen Kupplung solcher Art vorgeschlagen, daß durch Einrücken derselben die Kupplung nach dem Hauptpatent unwirksam gemacht wird. Die zusätzliche Kupplung kann, nur im umgekehrten. Drehsinn wirkend, in seiner Ausbildung der nach dem Hauptpatent vorzusehenden gleich sein, so daß bei eingerückter zusätzlicher Kupplung das Gestänge in beiden Drehrichtungen angetrieben werden kann.In order to create the possibility of using the turntable in the opposite direction to drive, e.g. B. when carrying out fishing work, without the possibility of advance having to do without the drilling operation according to the main patent, the arrangement a special clutch of this type proposed that by engaging the same the clutch is rendered ineffective according to the main patent. The additional clutch can, only in reverse. Acting sense of rotation, in its training that according to the main patent to be provided the same, so that the linkage when the additional clutch is engaged can be driven in both directions of rotation.

Die bauliche Ausgestaltung der Erfindung kann so getroffen werden, daß beide Kupplungen auf sein ;gemeinsames Treibrad zur Einwirkung kommen.The structural design of the invention can be made so that both clutches are on; common drive wheel come into play.
