Description
Die Erfindung stellt eine Bajonettkupplung dar, die eine schnelle und sichere Verbindung der Bohrerstange mit der Bohrerschneide gewährleistet.The invention represents a bayonet coupling that provides a quick and secure connection the drill rod with the drill bit guaranteed.
Es sind bereits Kupplungen dieser Art zur Verbindung von Bohrerstange und Bohrerschneide bekannt, die aber in ihrer Bauart, insbesondere in der Anordnung der Verbindung, unpraktisch sind und von der Erfinto dung -wesentlich abweichen.There are already couplings of this type for connecting the drill rod and drill bit known, but in their design, especially in the arrangement of the connection, are impractical and deviate significantly from the invention.
Zu den bekannten Verbindungen der Bohrerstange und der Bohrerschneide werden ausschließlich Splinte, Stellschrauben oder andere lose Teile angewendet. Diese Verbindungsarten haben für die Bohrerschneide viele Nachteile gezeitigt.Be the known connections of the drill rod and the drill bit only split pins, set screws or other loose parts are used. These types of connections have had many disadvantages for the drill bit.
Ein Lostrennen der Bohrerschneide im Bohrloch ist gemäß der Erfindung ausgeschlossen, da bei ihr keine Einzelteile in Anwendung kommen.A loose separation of the drill bit in the borehole is excluded according to the invention, since no individual parts are used with it.
Ein besonderer weiterer Vorteil der Erfindung besteht darin, daß durch die Anschläge der Bohrerstange die Drehkräfte von . der Bohrerschneide aufgenommen werden, wogegen bei den bekannten Verbindungen die Übertragung der Drehkräfte zur Bohrerschneide mittels Splint, Keil oder Stellschraube erfolgt und daher beim Abbrechen dieser Teile während des Bohrens die Bohrerschneide im Bohrloch steckenbleibt.Another particular advantage of the invention is that the stops the drill rod the torsional forces of. the cutting edge of the drill, whereas in the known connections, the transmission of the rotational forces to the drill bit by means of a split pin, wedge or set screw and therefore the cutting edge of the drill when these parts break off during drilling stuck in the borehole.

Abb. 3 eine Draufsicht auf die Bohrerstange mit Aussparung und Anschlagflügeln. Das Einsetzen der Bohrerschneide α bzw. des Zapfens b in die Bohrerstange ist hierbei sehr einfach.Fig. 3 is a top view of the drill rod with recess and stop wings. The insertion of the drill bit α or the pin b into the drill rod is very easy here.
Der Zapfen b wird in Querlage zur Bohrerschaftachse gehalten und dann die Bodenscheibe/ in die seitliche Aussparung d der Bohrerstangec unter Hindurchführung -der Bodenscheibe/ durch die Nuten«· und ^1 in die Öffnung h eingeführt, hierauf in Längslage geschwenkt und nach Verdrehung um seine Achse um 900 und Hindurchtreten der Federnd und ex durch die Nuteng- und ^1 in senkrechter Stellung in die Kammer i geschoben. The pin b is held in a transverse position to the drill shaft axis and then the bottom washer / is inserted into the side recess d of the drill rod c with the passage of the bottom washer / through the grooves «· and ^ 1 into the opening h , then pivoted in the longitudinal position and turned around its axis by 90 0 and passage of the resilient and e x with the Nuteng- and pushed i ^ 1 in a vertical position in the chamber.
Nach erneuter Verdrehung um seine Achse gelangen die Flügel k und kt zum Anschlag gegen entsprechende Gegenanschläge der Bohrerschneide β, wodurch diese gesichert ist.After another rotation about its axis, the wings k and k t come to a stop against corresponding counter-stops of the drill bit β, whereby it is secured.
