Description

Die Erfindung betrifft einen Gesteinsbohrhammerhalter der mit einem Hohldorn, durch ■den der Bohrer hindiurchtritt, in das Gebirge eingeführt wird.The invention relates to a rock drill holder with a hollow mandrel ■ that the drill passes through, into the mountains is introduced.

Nach der Erfindung erhält der Hohldorn des Bohrhammerhalters einen oder mehrere Schlitze, sie so breit sind, daß die Bohrerschneide hindurchgeführt werden kann.According to the invention, the hollow mandrel of the hammer drill holder receives one or more Slots, they are so wide that the drill bit can be passed through.

Der Durchmesser des Hohldorns braucht ίο daher im Außendurchmesser nicht größer zu sein, als der Durchmesser der Bohrerschneide. Es braucht somit zum Vorbohren des Loches für den Hohldorn nicht mehr Zeit aufgewandt zu wenden als für das Boh:- ren des gewöhnlichen Bohrloches.The diameter of the hollow mandrel therefore does not need to be larger in the outer diameter than the diameter of the drill bit. It is therefore no longer necessary to pre-drill the hole for the hollow mandrel Time spent turning than for the boh: - ren the ordinary borehole.

Die Verwendung der Erfindung ist nicht allein auf selbsttätig wirkende Vorschubvorrichtungen beschränkt.
• In der beiliegenden Zeidhlming· ist eiine Ausao führungsform des Erfindungsgegenstandes wiedergegeben, und zwar in Abb. ι im Aufriß und Abb. 2 im Grundriß.The use of the invention is not limited solely to automatically acting feed devices.
• In the attached Zeidhlming · an embodiment of the subject invention is reproduced, namely in Fig. 1 in elevation and Fig. 2 in plan.

Es stellt α den Hohldorn des Bohrhammerhalters dar, der bei b einen oder mehrere Schlitze erhält, durch die die Bohrerschneide c hindurchgeführt werden kann. Bei d ist der Bohrhammerhalter und hinter e wird der Bohrhammer gesetzt.It represents α the hollow mandrel of the hammer drill holder, which receives one or more slots at b through which the drill bit c can be passed. The hammer drill holder is at d and the hammer drill is placed behind e.

"Wie leicht ersichtlich,, kann durch den Schlitz des Hohldorns die Schneide des Bohrers hindurchgeführt werden, so daß also ein größeres Loch für den Hohldorn nicht vorgebohrt zu werden braucht."As can easily be seen, through the The cutting edge of the drill is passed through the slot of the hollow mandrel, so that a larger hole for the hollow mandrel does not need to be pre-drilled.
