Description

In. der Häuptpatentschrift ist ein Bohrervorschub dargestellt, welcher im Innern eines Kernbohrers angeordnet ist. Hiervon unterscheidet sich der Gegenstand der vorliegenden Zusatzerfindung dadurch, daß die für einen Vollbohrer bestimmte Vorschubvorrichtung außerhalb um den Bohrer angeordnet ist.In. the main patent is a drill feed shown, which is arranged inside a core drill. This differs from this the subject of the present additional invention in that the feed device intended for a full drill is arranged outside around the drill.

In der Zeichnung ist eine derartige Vorrichtung in Ansicht mit teilweisem Schnitt dargestellt. Von einer rohrartigen Hülse b, . deren Inneres ihrer ganzen Länge nach mit einem Gewinde versehen ist, wird ein in der Hülse frei bewglicher Vollbohrer α umschlossen, der mit seinem Befestigungszapfen d in einem in dem Hülsengewinde geführten, schraubenartigen Körper c steckt, so daß er unten herausragt. Der vordere, aus der Hülse b herausragende Teil des - Bohrers a wird von einer mit einem Klemmring f versehenen Drehvorrichtung e umklammert. Wird nun der Bohrer α nach rechts gedreht, so macht der Teil c die Bewegung mit, schraubt sich in Bohrrichtung in der Hülse b vorwärts und bewirkt dadurch das Eindringen des Bohrers ins Gestein. Ist der Bohrer α bis zum Klemmring f. ins Gestein eingedrungen, so wird die Flügelschraube g der Drehvorrichtung e gelöst, diese bis gegen die Hülse b zurückgenommen, mittels der Flügelschraube g der Klemmring f um den Bohrer α festgezogen und der Bohrvorgang in dieser Weise fortgesetzt, bis der Teil c das Ende der Hülse b erreicht hat. Damit der Bohrer a das Gewinde in der Hülse b nicht beschädigen kann, erhält er in dem Ring h Führung.In the drawing, such a device is shown in a view with partial section. From a tubular sleeve b,. the inside of which is provided with a thread along its entire length, a fully movable drill α is enclosed, which is inserted with its fastening pin d in a guided in the sleeve thread, screw-like body c so that it protrudes below. The front part of the drill a protruding from the sleeve b is clasped by a rotating device e provided with a clamping ring f. If the drill α is now turned to the right, part c follows the movement, screws itself forward in the drilling direction in the sleeve b and thereby causes the drill to penetrate into the rock. If the drill α has penetrated the rock up to the clamping ring f. , The wing screw g of the turning device e is loosened, it is withdrawn up to the sleeve b , the clamping ring f is tightened around the drill α by means of the wing screw g and the drilling process is continued in this way until part c has reached the end of sleeve b . So that the drill a cannot damage the thread in the sleeve b , it is guided in the ring h.

Das Herausnehmen des Bohrers geschieht entweder dadurch, daß der Teil c mittels des Bohrers α bis zum unteren Ende der Hülse b zurückgeschratibt wird, so daß das Zapfenende d gegen den Hülsenboden drückt und den Bohrer α aus dem Teil c herausstößt, oder in jeder beliebigen anderen Stellung, indem die Drehvorrichtung e, f bis gegen die Hülse b zurückgenommen und entgegengesetzt der Bohrrichtung gedreht wird. Der Teil c schraubt sich dadurch in die Hülse b hinein, der Bohrer α kann der Bewegung nicht folgen und muß sich infolge seiner Hemmung selbsttätig aus dem Teil.r herausziehen.The removal of the drill is done either by the fact that the part c is scraped back to the lower end of the sleeve b by means of the drill α, so that the pin end d presses against the sleeve base and the drill α pushes out of the part c , or in any other Position by taking the turning device e, f back against the sleeve b and turning it in the opposite direction to the drilling direction. The part c is screwed into the sleeve b , the drill α cannot follow the movement and must automatically pull itself out of the part r due to its inhibition.

Die Vorschubregelung erfolgt dadurch, daß die Hülse b mittels Handrades i entgegengesetzt der Bohrerdrehung gedreht wird. Wird der am Widerlager k beweglich angeordnete Hebel I so gestellt, daß er das Widerlager k mit der Hülse b starr verbindet, wie in der Zeichnung dargestellt, so wird der Bohrer α entsprechend der Steigung des Gewindeganges in der Hülse b vorgeschoben. Wird der Hebel I zurückgenommen, wodurch die Teile k und b .wieder voneinander getrennt werden, so ist der Bohrervorschub regelbar.The feed control takes place in that the sleeve b is rotated by means of the hand wheel i in the opposite direction to the rotation of the drill. If the lever I movably arranged on the abutment k is positioned so that it rigidly connects the abutment k to the sleeve b , as shown in the drawing, the drill α is advanced according to the pitch of the thread in the sleeve b. If the lever I is withdrawn, whereby the parts k and b are separated from each other again, the drill feed can be regulated.
