Description

Die Erfindung betrifft ein Bohrgestänge mit auswechselbarem Bohrer, bei dem die Verbindung der beiden Teile miteinander derart sicher ist, daß einerseits der Bohrer sich im Bohrloch, nicht lösen kann, anderseits das Gewinde, das die Verbindung herstellt, durch die Bohrarbeit nicht beansprucht wird, sondern völlig entlastet ist.The invention relates to a drill pipe with interchangeable drill, in which the connection of the two parts with each other in such a way What is certain is that on the one hand the drill cannot loosen in the borehole, on the other hand that The thread that creates the connection is not stressed by the drilling work, but rather is completely relieved.

Die Erfindung ist in der Zeichnung inThe invention is shown in the drawing in

ίο einem Ausführungsbeispiel dargestellt.ίο shown an embodiment.

An dem Bohrer α befindet sich ein Zapfen fr, der ein kurzes Gewindestück c besitzt. Im Gestänge d ist eine Bohrung e zur Aufnahme des Zapfens b angebracht, die ein dem Gewindestück c entsprechendes Muttergewinde f enthält. Die Bohrung setzt sich aber hinter diesem· Muttergewinde noch um ein. Stück g, das etwas länger ist als das Gewindestück c, fort.On the drill α there is a pin fr, which has a short thread piece c . In the linkage d a hole e is made for receiving the pin b , which contains a nut thread f corresponding to the threaded piece c . However, the hole continues behind this nut thread. Piece g, which is slightly longer than the threaded piece c, is gone.

Der Zapfen b wird so in die Bohrung e eingedreht, daß sich das Gewinde c durch das Muttergewinde / hindurchschraubt und in den Raum g eintritt. Beim Bohren legen sich die Stirnflächen des Bohrers h und des Gestänges i aufeinander und nehmen den Bohrdruck auf. Die Fläche i ist mit Nasen k versehen, die in entsprechende Vertiefungen in der Fläche h eintreten und als Mitnehmer wirken.The pin b is screwed into the bore e in such a way that the thread c screws through the nut thread / and enters the space g . When drilling, the end faces of the drill bit h and the rod assembly i lie on top of one another and absorb the drilling pressure. The surface i is provided with noses k which enter corresponding depressions in the surface h and act as drivers.

Die Verbindung kann nur durch Linksdrehen gelöst werden. Ein Herausziehen des Bohrers ist nicht möglich', da das Gewinde c wie ein Bund wirkt. Im übrigen ruht es während des Bohrens völlig unbelastet im Raum g der Bohrung e. The connection can only be released by turning it to the left. It is not possible to pull out the drill because the thread c acts like a collar. In addition, it rests completely unloaded in space g of bore e during drilling.
