III. Technisches Grundproblem/-frageIII. Basic technical problem / question
Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Möglichkeit der Entriegelung der Fangvorrichtung von Gegenständen, bspw. von Seilkernrohren zu entwickeln, die im ferngesteuerten Betrieb ohne manuelle Unterstützung außerhalb des Bohrgestänges durchgeführt werden kann. Sämtliche aktuellen, handelsüblichen Fangvorrichtungen erfordern eine manuelle Entriegelung durch den Bohrgeräteführer. Im Standardverfahren des Seilkernbohrens sichert der Bohrmeister das Innenkernrohr nach dem Ziehen aus dem Bohrstrang, um dann manuell den Hakenfänger vom Dorn zu trennen (z. B. in dem er die Schnapphaken durch Fingerdruck gegen den Federwiderstand öffnet).Of the The invention defined in claim 1 is based on the problem a way of unlocking the safety gear of To develop objects, for example of rope core tubes, in the remote controlled operation without manual assistance outside the drill string can be performed. All require current, commercially available safety gears a manual release by the drill guide. In the standard method of rope core drilling, the drill master secures the inner core tube after pulling out of the drill string, then manually To separate the hook catcher from the thorn (eg in which he the Snap hook opens by finger pressure against the spring resistance).
IV. LösungIV. Solution
Dieses Problem wird durch das im Patentanspruch 1 aufgeführte Merkmal, dass der Hakenfänger durch ein einfaches Zugentlasten am Seil gelöst werden kann, gelöst.This Problem is indicated by the in claim 1 Feature that the hook catcher by a simple strain relief can be solved on the rope, solved.
V. Vorteile der ErfindungV. Advantages of the invention
Mit dieser Erfindung kann der Hakenfänger außerhalb eines Bohrstranges ohne zusätzliche Manipulation gelöst werden und muss vor dem nächsten Einsatz nicht neu eingestellt werden. Dies ist insbesondere bei ferngesteuerten Bohrgeräten von Bedeutung, die bspw. beim Seilkernbohrverfahren angewendet werden.With This invention allows the hook catcher outside a drill string solved without additional manipulation will not have to be reset before next use become. This is especially true for remote-controlled drilling rigs important, which are used, for example, in the Seilkernbohrverfahren.

VII. AusführungsbeispielVII. Embodiment
Bei der Erfindung handelt es sich um einen Hakenfänger, mit dem ein Seilkern-Innenrohr oder ein anderes Werkzeug (z. B. ein Bohrlochmessgerät), das an seinem Kopfende mit einem Dorn ausgerüstet ist, im Bohrstrang gegriffen und mit Hilfe eines Seils aus dem Bohrgestänge gezogen werden kann. Nach Sichern des Seilkern-Innenrohres bzw. des Werkzeuges gegen einen Rückfall in den Bohrstrang, kann der Hakenfänger durch einfaches Zugentlasten am Seil vom Dorn gelöst werden.at the invention is a hook catcher, with a cable core inner tube or other tool (eg Borehole gauge), which at its head end with a thorn equipped, seized in the drill string and with the help a rope can be pulled out of the drill string. To Secure the inner core of the rope core or the tool against a Relapse into the drill string, the hook catcher can be released from the mandrel by simple strain relief on the rope.
