Description

Die Erfindung betrifft einen Keil, wie er insbesondere bei Grubenstempeln 'als Anstellkeil oder Setzkeil Anwendung findet.The invention relates to a wedge of the type used in particular in pit punches '' is used as an adjusting wedge or setting wedge.

Diese Keile wurden bisher mit schwerenHämmern eingetrieben und gelöst. Die Notweüdigkeit, diese Hämmer vor Ort mitzuführen, bedeutet für den Bergbaubetrieb eine unerwünschte Belastung. Das Schlagen mit denn; Hämmern ist unter den beschränkten Raumverhältnissen im Untertagebetrieb häufig schwierig. Die Hämmer können leicht verlorengehen.These wedges were previously driven in and loosened with heavy hammers. The need to carry these hammers on site means for the mining company an undesirable burden. The beating with then; Hammering is among the restricted Space conditions in underground operations are often difficult. The hammers can easily get lost.

Erfindungsgemäß wird daher vorgeschlagen, in einer Stirnfläche oder vorzugsweise beiden Stirn, flächen Vertiefungen vorzusehen, in die das Werkzeug eines handbetätigten Preßluftabbaugerätes, beispielsweise das Spitzeisen eines Abbauhammers, einsetzbar ist. Vorzugsweise ist diese Vertiefung derart ausgebildet, daß die Schoneiden oder die arbeitenden Kanten. .des Werkzeuges im eingesetzten Zustande im Innern der Vertiefung frei liegen. Hierdurch wird eine Beschädigung dieser Schneiden oder arbeitenden. Kanten des Werkzeuges vermieden.According to the invention it is therefore proposed in an end face or Preferably, both forehead, planar recesses to be provided in which the tool a hand-operated compressed air removal device, for example the tip of a removal hammer, can be used. This recess is preferably designed in such a way that the Schoneiden or the working edges. . of the tool in the inserted state inside the recess are exposed. This will damage this cutting or working. Avoided edges of the tool.

Keile gemäß der Erfindung gestatten das bequeme und rasche Eintreiben und Lösen der Keile von Grubenstempeln ohne Verwendung eines Hammers unter Benutzung eines ohnehin in der Hand des Bergmanns vor Ort befindlichen Werkzeuges.Wedges according to the invention allow easy and quick driving and releasing the wedges from pit punches without using a hammer, using a tool already in the hands of the miner on site.

In der Zeichnung ist ein Keil für Grubenstempel gemäß der Erfindung beispielsweise dargestellt und das eingesetzte Werkzeug angedeutet.In the drawing is a wedge for pit punches according to the invention shown for example and indicated the tool used.

Der Grubenstempelkeil i ist an seinen beiden Stirnflächen 2, 2' mit kegeligen Bohrungen 3, 3' versehen. In die Bohrung 3 greift beispielsweise das Werkzeug q. des Preßluftabbaugerätes ein. Die Kegelform der Bohrungen 3, 3' ist so gewählt, daß nur nichtarbeitende Teile des Werkzeuges an den Innenflächen der Bohrungen 3, 3' anliegen.The pit punch wedge i is on both of its end faces 2, 2 ' tapered bores 3, 3 'provided. The tool, for example, engages in the bore 3 q. of the compressed air removal device. The conical shape of the bores 3, 3 'is chosen so that that only non-working parts of the tool on the inner surfaces of the holes 3, 3 '.

Keile gemäß der Erfindung können selbstverständlich überall da Anwendung finden, wo die gleichen Gründe wie im Bergbaubetrieb für einen Ersatz des Hammers maßgebend sein können.Wedges according to the invention can of course be used anywhere find where the same reasons as in the mining company for a replacement of the hammer can be authoritative.
