KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf drehende Gesteinbohrmaschinen, welche beim Auswechseln des Bohrers ihre ursprüngliche Stellung innebehalten, so dafs der neu eingesetzte Bohrer genau in das Bohrloch des herausgenommenen sich einstellt.The present invention relates to rotary rock drilling machines which are used in Replacing the drill keep their original position, so that the newly inserted one Drill exactly into the borehole of the removed one.
Bei den bekannten Maschinen dieser Art werden entweder zweitheilige Bohrmuttern benutzt, deren Hälften so weit aus einander gerückt werden können, dafs die Bohrerspindel hindurchgezogen werden kann, oder das Auswechseln wird durch Zurückkurbeln der Bohrerspindeln ermöglicht.In the known machines of this type, either two-part drill nuts are used, the halves of which can be moved so far apart that the drill spindle can be pulled through, or the replacement is done by cranking back the drill spindles enables.
Gegenüber derartigen Anordnungen, welche entweder eine complicirte Bauart der Maschine bedingen oder zum Auswechseln des Bohrers grofsen Zeitaufwand erfordern, zeichnet sich der Erfindungsgegenstand durch Einfachheit und bequeme Handhabung aus.Compared to such arrangements, which are either a complicated construction of the machine or require a great deal of time to change the drill the subject matter of the invention is characterized by simplicity and ease of use.
Die Vorrichtung ist auf der Zeichnung inThe device is shown in the drawing
Fig. ι in seitlicher Ansicht, inFig. Ι in side view, in
Fig. 2 im Längsschnitt dargestellt.Fig. 2 shown in longitudinal section.
Die Bohrmaschine ist mittelst des Armes 8 auf der Spannsäule 7 eingestellt. Die Bohrspindel ι mit der Vorschubschraube 2 wird in dem aus Rundeisen 5 gebildeten Rahmen geführt. Der Antrieb erfolgt z. B, mittelst Preisluft unter Vermittlung des Zahnrades 4, das Vorschieben des Bohrers mittelst des Handrades 3.The drill is set on the clamping column 7 by means of the arm 8. The drilling spindle ι with the feed screw 2 is guided in the frame formed from round iron 5. The drive takes place z. B, by means of price air with the mediation of the gear 4, the Advance the drill by means of the handwheel 3.
Die Neuerung besteht darin, dafs der Rahmen 5, 5 aus zwei bei 6 gelenkig verbundenen Theilen besteht. Zum Auswechseln des Bohrers wird die Schraubenspindel 2 zurückgezogen, so dafs sie aufser Eingriff mit der Bohrerspindel ι kommt und der hintere Theil des Rahmens seitlich umgelegt werden kann; hierauf wird der Bohrer herausgezogen und durch einen neuen ersetzt, der sich, da der vordere Theil der Maschine unberührt geblieben ist, genau in das Bohrloch einstellt. Nach Zurückdrehen des Rahmens und Vorschieben der Schraubenspindel befindet sich der neue Bohrer wieder in der Arbeitsstellung.The innovation is that the frame 5, 5 consists of two articulated at 6 Part consists. To change the drill, the screw spindle 2 is withdrawn, so that it comes out of engagement with the drill spindle and the rear part of the Frame can be turned sideways; then the drill is pulled out and through replaces a new one, which, since the front part of the machine has remained untouched, adjusts exactly in the borehole. After turning back the frame and pushing the The new drill is in the working position again.
