Description
Die Erfindung bezieht sich auf die Befestigung von Bohrstangen im Bohrkopf von Gesteindrehbohnmaschinen. Sie besteht in einer solchen Ausbildung des Bohrkopfes, daß die Bohrstange ohne Änderung ihres Profiles in den Bohrkopf eingesetzt werden kann. Die Bohrstangen haben häufig ein mehrflügeliges Profil. Je nach der Zahl der Flügel erhält der Bohrkopf Einschnitte, die in ihrer Richtung der Steigung der Bohrstangenwindungen entsprechen.The invention relates to the fastening of drill rods in the drill head of gesture lathe machines. It consists in such a design of the drill head that the drill rod without changing its profile in the drill head can be used. The boring bars often have a multi-wing one Profile. Depending on the number of wings, the drill head receives cuts in their direction correspond to the pitch of the boring rod windings.
In der Zeichnung ist als Ausführungsfoeispiel ein vierflügeliges Bohrstangenprofil· angenommen. Fig. ι zeigt eine Ansicht des Bohrkopfes und der Stange, die Fig. 2 und 3 einen Schnitt und eine Ansicht von oben des Bohrkopfes allein.In the drawing is an exemplary embodiment a four-wing boring bar profile · assumed. Fig. Ι shows a view of the Drill head and the rod, FIGS. 2 and 3 a section and a view from above of the Drill head alone.
In dem Bohrkopf α, der in beliebiger Weise mittels der Welle b mit dem Antrieb der Drehbohrmaschine verbunden ist, sind Schlitze oder Einschnitte c angebracht. In diese Schlitze, die die gleiche Steigung wie die Bohrstangenflügel haben, passen die Flügel der einfach senkrecht zur Längsachse abgeschnittenen Bohrstange d. Beim Einsetzen in den Bohrkopf α wird die Stange d nur locker von dem Kopf α getragen. Sobald aber ein Bohrdruck ausgeübt wird, schraubt sich die Bohrstange d in den Kopf α hinein und wird von diesem mitgenommen. Um der Stange d schon beim Einsetzen in den Bohrkopf α eine Führung zu geben, kann man an dem Kopf a eine Hülse e anbringen, welche die Stange d auf ein kurzes Stück stützt. Diese Hülse e kann auf beliebige Weise mit dem Kopf a verbunden sein, z. B. dadurch, 'daß sie warm aufgezogen wird. In der Hülse 0 findet die Bohrstange ei so viel Reibung, daß sie nicht herausfällt, auch wenn die Maschine ohne Bdhrdruck schräg, abwärts gehalten wird. Um die Bohr- 4c stange d auch gegen Herausfallen zu sichern, wenn die Maschine ohne Bohrdruck senkrecht nach unten gehalten wird, kann man die Reibung der Stange d in der Hülse e durch eine Feder o. dgl. erhöhen.In the drill head α, which is connected in any way by means of the shaft b to the drive of the rotary drill, slots or incisions c are made. In these slots, which have the same pitch as the boring bar wings, fit the wings of the boring bar d simply cut perpendicular to the longitudinal axis. When inserted into the drill head α , the rod d is only loosely carried by the head α . But as soon as a drilling pressure is exerted, the drill rod d screws into the head α and is carried along by this. In order to give the rod d a guide as soon as it is inserted into the drill head α , a sleeve e can be attached to the head a, which supports the rod d on a short piece. This sleeve e can be connected to the head a in any way, e.g. B. by 'that it is raised warm. In the sleeve 0 , the boring bar finds so much friction that it does not fall out, even if the machine is held obliquely downwards without bdhrdruck. In order to secure the drilling rod d against falling out when the machine is held vertically downwards without drilling pressure, the friction of the rod d in the sleeve e can be increased by a spring or the like.
