Vorrichtung zum Erweitern von Bohrlöchern.Device for expanding boreholes.

Patentiert im Deutschen Reiche vom 25. Oktober 1922 ab.Patented in the German Empire on October 25, 1922.

Die Erfindung betrifft eine Vorrichtung zum Herstellen weiter Bohrlöcher. Um durch tiefes Bohren genau gerichtete Bohrlöcher herzustellen, wird nach der Erfindung zunächst in bekannter Weise ein enges Bohrloch erzeugt und dieses dann mittels einer Bohrvorrichtung erweitert, bei welcher an einem Bohrkopf in der Mitte einerseits das Gestänge und anderseits eine in das vorgebohrte Loch herabhängende Schwersteinge angreift, während seitlich' Meißel angebracht sind.The invention relates to a device for producing further boreholes. To get through To produce deep drilling precisely aligned boreholes is first of all according to the invention a narrow borehole is produced in a known manner and this is then carried out by means of a drilling device expanded, in which on a drill head in the middle on the one hand the rod and on the other hand, a heavy stones hanging down in the pre-drilled hole attacks while laterally 'chisels are attached.

Durch die Belastung des Bohrkopfes mit einer tief herabhängenden Schwerstange wird ein gutes, genaues Arbeiten der Meißel gesichert. Die Schwerstange verhindert dabei jegliches Abweichen von der Senkrechten.Due to the loading of the drill head with a low hanging drill collar a good, precise work of the chisel is ensured. The drill collar prevents this any deviation from the vertical.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt.In the drawing, an embodiment of the device is shown.

An den Bohrkopf a, der die Meißel b und c trägt, greift oben das Gestänge d und unten die Schwerstange e an. Es kann natürlich auch üher dem Bohrkopf in bekannter Weise noch eine Schwerstange angebracht werden. Die Schwerstange e hängt tief in das vorgebohrte Loch f herab und sichert eine genaue ίο Führung des Bohrkopfes. Sie müßte zu dem Zweck gegebenenfalls noch mit Führungsrollen versehen werden. The drill head a, which carries the chisels b and c , engages the linkage d at the top and the drill collar e at the bottom. Of course, a drill collar can also be attached to the drill head in a known manner. The drill collar e hangs down deep into the pre-drilled hole f and ensures precise guidance of the drill head. For this purpose, you might have to be provided with guide rollers.
