Insbesondere ist eine Verbindung zwischen einem Hammerkolben und einem Drehumsetzer gezeigt.From the DE 1 220 360 goes out a rock drilling with a trained for percussion ring bit. In particular, a connection between a hammer piston and a rotary converter is shown.

Bei den bekannten Bohrgeräten mit einem Schwingungsantrieb, welcher auch ein Schlagen umfassen kann, handelt es sich weitgehend um spezielle Entwicklungen. Aufgrund der begrenzten Stückzahlen zu derartigen speziellen Bohrgeräten ergeben sich entsprechend hohe Gerätekosten.In the known drills with a vibration drive, which may also include a beating, are largely special developments. Due to the limited quantities of such special drilling equipment correspondingly high equipment costs.

Der Erfindung liegt die Aufgabe zugrunde, eine Bohrvorrichtung anzugeben, welche bei einem einfachen Aufbau auch ein Bohren in Kombination mit einer Schwingungserzeugung durchführen kann. Weiterhin ist es Aufgabe der Erfindung, ein Verfahren zum Nachrüsten einer solchen Bohrvorrichtung anzugeben.The invention has for its object to provide a drilling device, which can perform a drilling in combination with a vibration generation in a simple structure. It is another object of the invention to provide a method for retrofitting such a drilling device.

Die Aufgabe wird zum einen durch eine Bohrvorrichtung mit den Merkmalen des Anspruchs 1 und zum anderen durch ein Verfahren zum Nachrüsten einer Bohrvorrichtung gemäß den Merkmalen des Anspruchs 9 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.The object is achieved on the one hand by a drilling apparatus having the features of claim 1 and on the other hand by a method for retrofitting a drilling apparatus according to the features of claim 9. Preferred embodiments are given in the dependent claims.

Die erfindungsgemäße Bohrvorrichtung ist dadurch gekennzeichnet, dass an dem Verbindungsende eine Drehkupplung mit einem ersten Kupplungsstück, welches axial fest und drehfest mit dem Verbindungsende verbunden ist, und einem zweiten Kupplungsstück vorgesehen ist, welches axial fest und drehbar relativ zum ersten Kupplungsstück ist, und dass der Schwingungsantrieb eine Spanneinrichtung aufweist, welche zum lösbaren Spannen des zweiten Kupplungsstücks ausgebildet ist, wobei im gespannten Zustand eine axial feste Verbindung zwischen dem Schwingungsantrieb und dem zweiten Kupplungsstück gebildet ist.The drilling device according to the invention is characterized in that at the connecting end of a rotary coupling with a first coupling piece, which axially fixed and rotatably connected to the connecting end, and a second coupling piece is provided, which is axially fixed and rotatable relative to the first coupling piece, and that the vibration drive comprises a clamping device which is designed for releasably tensioning the second coupling piece, wherein in the tensioned state, an axial solid connection between the vibration drive and the second coupling piece is formed.

Ein Grundgedanke der Erfindung kann darin gesehen werden, bei einer Bohrvorrichtung zum Erd- oder Gesteinsbohren zusätzlich einen separaten Schwingungsantrieb vorzusehen, welcher lösbar mit dem Bohrantrieb gekoppelt werden kann. Die Begriffe Schwingungsantrieb und Schwingung sind allgemein zu verstehen, wobei grundsätzlich diese nicht allein ein Vibrieren und Rütteln, sondern auch ein Schlagen oder sonstiges Schwingen umfassen können. Der Schwingungsantrieb kann bedarfsgerecht dem Bohrantrieb zugeschaltet werden.A basic idea of the invention can be seen to additionally provide a separate vibration drive in a drilling device for earth or rock drilling, which can be releasably coupled to the drill drive. The terms vibration drive and vibration are to be understood generally, and in principle these may not only vibration and shaking, but also include a beating or other swinging. The vibration drive can be switched to the drill drive as needed.

Dabei ist gemäß der Erfindung der Bohrantrieb in spezieller Weise so ausgebildet, dass ein Verbindungsende der Bohrantriebswelle des Bohrantriebes oder des Bohrgestänges selbst nach hinten aus dem Gehäuse des Bohrantriebs herausragt. An dem Verbindungsende ist axial fest und drehfest ein erstes Kupplungsstück einer Drehkupplung angebracht. Die Drehkupplung umfasst weiterhin ein zweites Kupplungsstück, welches axial fest und drehbar relativ zu dem ersten Kupplungsstück an diesem angeordnet ist. Das zweite Kupplungsstück ist dabei so ausgebildet, dass dieses mittels einer Spanneinrichtung an dem Schwingungsantieb erfasst werden kann, so dass eine die Schwingung des Schwingungsantriebs übertragende Verbindung über die Drehkupplung zur Bohrantriebswelle geschaffen ist. In einem gespannten Zustand kann so ein Bohren in Kombination mit gezielten Schwingungen erfolgen, was bei bestimmten Bodenverhältnissen zu einem erhöhten Bohrfortschritt führt. Dabei kann auch der gesamte Bohrantrieb mit in Schwingung versetzt werden. Der Bohrantrieb kann auch ringförmig ausgebildet sein, wobei das Bohrgestänge nach hinten aus dem Bohrantrieb herausragt. In entsprechender Weise kann an dem hinteren Verbindungsende des Bohrgestänges die beschriebene Drehkupplung vorgesehen sein.In this case, according to the invention, the drill drive is designed in a special way so that a connecting end of the drill drive shaft of the drill drive or of the drill pipe itself protrudes to the rear out of the housing of the drill drive. At the connection end is axially fixed and rotationally fixed a first coupling piece of a rotary coupling attached. The rotary coupling further comprises a second coupling piece, which is axially fixed and rotatable relative to the first coupling piece arranged thereon. The second coupling piece is designed so that it can be detected by means of a clamping device on the Schwingungsantieb, so that a vibration of the vibration drive transmitting connection is created via the rotary coupling to Bohrantriebswelle. In a tensioned state, drilling can take place in combination with targeted vibrations, which leads to increased drilling progress in certain soil conditions. In this case, the entire drill drive can be set in vibration. The drill drive can also be annular, wherein the drill string protrudes to the rear of the drill drive. In a corresponding manner may be provided at the rear connecting end of the drill string described rotary coupling.

Falls keine Schwingung benötigt wird, kann die Spanneinrichtung gelöst und der Schwingungsantrieb von dem Bohrantrieb entkoppelt werden. Hierdurch reduziert sich grundsätzlich eine innere Reibung der gesamten Antriebsanordnung im Bohrbetrieb.If no vibration is needed, the tensioning device can be released and the vibration drive can be decoupled from the drilling drive. As a result, an internal friction of the entire drive assembly in the drilling operation is reduced in principle.

Dies schont auch die Antriebe, reduziert den Wartungsaufwand und führt insgesamt zu einer erhöhten Lebensdauer der Antriebsanordnung.This also protects the drives, reduces maintenance and leads overall to an increased life of the drive assembly.

Aufgrund der lösbaren Verbindung und Anordnung des Schwingungsantriebs zum Bohrantrieb kann der Schwingungsantrieb zusätzlich als Option für normale Bohrvorrichtungen vorgesehen und angeboten werden. Auch ein Nachrüsten bestehender Bohrvorrichtungen ist grundsätzlich möglich.Due to the detachable connection and arrangement of the vibration drive to the drill drive of the vibration drive can be additionally provided and offered as an option for normal drilling devices. Also retrofitting existing drilling devices is basically possible.

Grundsätzlich kann die Spanneinrichtung in beliebiger Weise ausgestaltet sein, um eine geeignete schwingungsübertragende Verbindung zwischen dem Schwingungsantrieb und der Bohrantriebswelle zu schaffen.In principle, the tensioning means may be configured in any manner to provide a suitable vibration transmitting connection between the vibration drive and the drilling drive shaft.

Besonders bevorzugt ist es nach einer Ausführungsform der Erfindung, dass die Spanneinrichtung, insbesondere eine Spannzange mit radial verstellbaren Spannklauen zum kraft- und formschlüssigen Verbinden aufweist. Mit den Spanneinrichtungen kann allgemein eine kraft- und/oder formschlüssige Verbindung zu dem zweiten Kupplungsstück der Drehkupplung geschaffen werden. Das Spannen erfolgt über eine aktive Spannbetätigung.According to one embodiment of the invention, it is particularly preferred for the clamping device, in particular a collet with radially adjustable clamping claws, to have non-positive and positive connection. With the clamping devices can generally be created a positive and / or positive connection to the second coupling piece of the rotary joint. Clamping takes place via an active clamping operation.

Eine weitere vorteilhafte Ausführungsform der Erfindung besteht darin, dass der Schwingungsantrieb auf einem Schwingungsantriebsschlitten angebracht ist, welcher relativ zum Bohrantriebsschlitten verfahrbar ist. Der Schwingungsantriebsschlitten ist vorzugsweise entlang eines Mastes verschiebbar angeordnet. Zum Verschieben kann ein separater Verschiebeantrieb vorgesehen sein, welcher einen Stellzylinder oder eine Seilwinde umfassen kann. Mittels einer Steuerung kann der Schwingungsantrieb so zwischen einer Betriebsstellung, in welcher diese über die Spanneinrichtung mit dem Bohrantrieb gekoppelt werden kann, und einer Rückzugsposition verfahren werden, in welcher der Schwingungsantrieb mit dem Schwingungsantriebsschlitten von dem Bohrantrieb beabstandet ist.A further advantageous embodiment of the invention is that the vibration drive is mounted on a vibration drive carriage which is movable relative to the Bohrantriebsschlitten. The vibration drive carriage is preferably arranged displaceably along a mast. To move a separate displacement drive may be provided, which may include a control cylinder or a winch. By means of a control, the vibration drive can thus be moved between an operating position in which it can be coupled to the drill drive via the tensioning device and a retraction position in which the vibration drive with the vibration drive slide is spaced from the drill drive.

Nach einer Weiterbildung der erfindungsgemäßen Bohrvorrichtung ist es vorteilhaft, dass nach einem Lösen der Spanneinrichtung der Schwingungsantriebsschlitten mit dem Schwingungsantrieb von dem Bohrantrieb trennbar und entfernbar ist. Somit kann der Schwingungsantriebsschlitten mit dem Schwingungsantrieb aus dem unmittelbaren Arbeitsbereich des Bohrantriebs entfernt werden. Dies schont den Schwingungsantrieb.According to a development of the drilling device according to the invention, it is advantageous that after a release of the clamping device of the vibratory drive carriage with the vibratory drive of the drill drive is separable and removable. Thus, the vibratory drive carriage can be removed with the vibration drive from the immediate working area of the drill drive. This protects the vibration drive.

Grundsätzlich kann der Schwingungsantrieb in einer beliebigen und bekannten Weise ausgebildet sein, um gezielte Schwingungen zu erzeugen, welche auf ein rotierendes Bohrwerkzeug übertragen werden können. Dies kann insbesondere auch eine schlagende Schwingungserzeugung sein. Besonders bevorzugt ist es nach einer Ausführungsform der Erfindung, dass der Schwingungsantrieb als ein Rüttler ausgebildet ist.In principle, the vibration drive can be designed in any desired and known manner in order to generate targeted vibrations which can be transmitted to a rotating drilling tool. This can in particular also be a striking vibration generation. According to one embodiment of the invention, it is particularly preferred for the vibration drive to be designed as a vibrator.

Besonders vorteilhaft ist es dabei, dass der Rüttler mindestens ein Paar rotierend angetriebene Unwuchteinheiten aufweist. Insbesondere können mehrere rotierend angetriebene Unwuchteinheiten angeordnet sein, welche zueinander verstellbar sind. Hierdurch lässt sich eine nahezu stufenlose Einstellung und eine gezielte Ausrichtung der Vibrationen, insbesondere in Bohrrichtung, einstellen. Der Rüttler kann auch mit einem oszillierend angetriebenen Axialkolben zur Schwingungserzeugung ausgebildet sein.It is particularly advantageous that the vibrator has at least one pair of rotationally driven unbalance units. In particular, a plurality of rotationally driven unbalance units may be arranged, which are mutually adjustable. As a result, an almost stepless adjustment and a targeted alignment of the vibrations, in particular in the drilling direction, can be set. The vibrator can also be designed with an oscillating driven axial piston for vibration generation.

Nach einer weiteren bevorzugten Ausführungsvariante der Erfindung ist es vorgesehen, dass der Mast im Wesentlichen vertikal angeordnet ist. Der Mast kann dabei ein starrer Mast mit einer Linearführung oder ein sogenannter Mäkler sein. Der Mast kann insbesondere in einem gewissen Umfang schwenkbar um eine Vertikalachse oder kippbar hierzu gelagert sein.According to a further preferred embodiment of the invention, it is provided that the mast is arranged substantially vertically. The mast can be a rigid mast with a linear guide or a so-called leader. The mast can in particular be mounted to a certain extent pivotable about a vertical axis or tiltable thereto.

Eine weitere schonende Ausgestaltung der erfindungsgemäßen Bohrvorrichtung kann darin gesehen werden, dass der Schwingungsantrieb am Schwingungsantriebsschlitten schwingungsdämpfend gelagert ist. Insbesondere kann eine weitgehende Entkopplung des Schwingungsantriebs von einem Grundschlitten erzielt werden, etwa indem Gummilager dazwischen angeordnet sind. Hierdurch kann eine übermäßige Übertragung von Schwingungen von dem Schwingungsantrieb auf den Mast und das Bohrgerät insgesamt vermieden werden.Another gentle embodiment of the drilling device according to the invention can be seen in that the vibration drive is mounted on the vibration drive slide vibration damping. In particular, a substantial decoupling of the vibration drive can be achieved by a base carriage, such as by rubber bearings are arranged therebetween. In this way, an excessive transmission of vibrations from the vibration drive to the mast and the drill can be avoided altogether.

Das erfindungsgemäße Verfahren zum Nachrüsten einer Bohrvorrichtung zum Erd- oder Gesteinsbohren ist dadurch gekennzeichnet, dass an einem hinteren Verbindungsende der Bohrantriebswelle des Bohrantriebes oder des Bohrgestänges eine Drehkupplung mit einem ersten Kupplungsstück, welches axial fest und drehfest mit dem Verbindungsende verbunden wird, und einem zweiten Kupplungsstück vorgesehen wird, welches axial fest und drehbar relativ zum ersten Kupplungsstück ist, und dass hinter dem Bohrantrieb ein Schwingungsantrieb mit einer Spanneinrichtung angeordnet wird, welche zum lösbaren Spannen des zweiten Kupplungsstücks ausgebildet ist, wobei im gespannten Zustand eine axial feste Verbindung zwischen dem Schwingungsantrieb und dem zweiten Kupplungsstück gebildet ist.The method according to the invention for retrofitting a drilling device for earth or rock drilling is characterized in that at a rear connecting end of the drill drive shaft of the drill drive or the drill string, a rotary coupling with a first coupling piece which is axially fixed and rotatably connected to the connecting end, and a second coupling piece is provided, which is axially fixed and rotatable relative to the first coupling piece, and arranged behind the drill drive a vibratory drive with a clamping device is, which is designed for releasably tensioning the second coupling piece, wherein in the tensioned state, an axially fixed connection between the vibration drive and the second coupling piece is formed.

Mit diesem Verfahren können grundsätzlich herkömmliche Bohrvorrichtungen, welche bisher ohne einen Schwingungsantrieb ausgebildet sind, nachgerüstet werden. Dabei kann insbesondere der Schwingungsantrieb auf einem Schwingungsantriebsschlitten angeordnet werden, welcher entlang einer Führung an dem Mast verfahrbar ist, an welchem auch der Bohrantrieb mit einem Bohrantriebsschlitten verfahren wird. Somit kann in effizienter Weise eine bestehende Bohrvorrichtung bedarfsgerecht mit einer zusätzlichen Vibrations- oder Schwingungseinrichtung versehen werden.With this method, basically conventional drilling devices which have hitherto been formed without a vibration drive can be retrofitted. In this case, in particular, the vibration drive can be arranged on a vibration drive slide, which is movable along a guide on the mast, on which also the drill drive is moved with a Bohrantriebsschlitten. Thus, an existing drilling device can be efficiently provided with an additional vibration or vibration device as needed.

Mit dem erfindungsgemäßen Verfahren kann insbesondere die zuvor beschriebene Bohrvorrichtung hergestellt werden. Dabei können die zuvor beschriebenen Vorteile erzielt werden.With the method according to the invention, in particular, the drilling device described above can be produced. In this case, the advantages described above can be achieved.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels weiter beschrieben, welches schematisch in der beigefügten Zeichnung dargestellt ist.The invention will be further described below with reference to a preferred embodiment, which is shown schematically in the accompanying drawing.

Eine erfindungsgemäße Bohrvorrichtung 10 ist in der Zeichnung schematisch in Seitenansicht dargestellt. Die Bohrvorrichtung 10 weist einen Bohrantrieb 20 und einen Schwingungsantrieb 30 auf, welcher in Bohrrichtung hinter dem Bohrantrieb 20 angeordnet ist. Der Bohrantrieb 20 ist auf einem Bohrantriebsschlitten 24 gelagert und entlang einer nicht näher dargestellten Linearführung an einem nur verkürzt dargestellten Mast 12 verschiebbar gelagert. In entsprechender Weise ist der Schwingungsantrieb 30 über einen Schwingungsantriebsschlitten 34 entlang der Linearführung am Mast 12 gelagert. Der Mast 12 ist vorzugsweise an einem nicht dargestellten Trägerfahrzeug angeordnet.A drilling device 10 according to the invention is shown schematically in the drawing in side view. The drilling apparatus 10 has a drill drive 20 and a vibration drive 30, which is arranged behind the drill drive 20 in the drilling direction. The drill drive 20 is mounted on a Bohrantriebsschlitten 24 and slidably mounted along a linear guide not shown on a mast 12 shown only shortened. In a corresponding manner, the vibration drive 30 is mounted on the mast 12 via a vibration drive slide 34 along the linear guide. The mast 12 is preferably arranged on a carrier vehicle, not shown.

Der Bohrantrieb 20 weist eine Bohrantriebswelle 22 auf, welche an ihrem vorderen Ende mit einem nicht dargestellten Bohrgestänge verbunden werden kann. Der Bohrantrieb 20, welcher insbesondere einen Hydraulikmotor umfasst, erzeugt ein Drehmoment, welches über die Bohrantriebswelle 22 auf das Bohrgestänge übertragen wird. Die Bohrantriebswelle 22 ist axial verschiebbar in einem Gehäuse des Bohrantriebs 20 gelagert, wobei nach hinten ein hinteres Verbindungsende 26 herausragt. Das hintere Verbindungsende 26 ist mit der Bohrantriebswelle 22 verbunden und stellt insbesondere das hintere Ende der Bohrantriebswelle 22 dar. An dem hinteren Verbindungsende 26 ist eine Drehkupplung 40 angebracht, welche ein nicht näher dargestelltes erstes Kupplungsstück und ein zweites Kupplungsstück aufweist. Das erste Kupplungsstück der Drehkupplung 40 ist axial fest und drehfest mit dem hinteren Verbindungsende 26 der Bohrantriebswelle 22 verbunden. Das zweite Kupplungsstück der Drehkupplung 40 ist axial fest mit dem ersten Kupplungsstück und relativ drehbar zu dem ersten Kupplungsstück gelagert.The drill drive 20 has a drill drive shaft 22, which can be connected at its front end with a drill string, not shown. The drill drive 20, which in particular comprises a hydraulic motor, generates a torque, which is transmitted via the drill drive shaft 22 to the drill pipe. The drill drive shaft 22 is axially displaceably mounted in a housing of the drill drive 20, wherein a rear connecting end 26 protrudes to the rear. The back Connecting end 26 is connected to the Bohrantriebswelle 22 and in particular represents the rear end of the Bohrantriebswelle 22. At the rear connecting end 26, a rotary coupling 40 is mounted, which has a not shown in detail first coupling piece and a second coupling piece. The first coupling piece of the rotary coupling 40 is axially fixed and non-rotatably connected to the rear connecting end 26 of the drill drive shaft 22. The second coupling piece of the rotary coupling 40 is mounted axially fixed to the first coupling piece and relatively rotatable to the first coupling piece.

Der Schwingungsantrieb 30, welche insbesondere einen Rüttler mit mehreren rotierend angetriebenen Unwuchtelementen aufweist, umfasst eine vordere, zum Bohrantrieb 20 gerichtete Spanneinrichtung 32. Die Spanneinrichtung 32 ist insbesondere eine Spannzange mit radial verstellbaren Spannklauen 36. Mit den Spannklauen 36 der Spanneinrichtung 32 kann das zweite Kupplungsstück kraftschlüssig und/oder formschlüssig erfasst werden. Auf diese Weise kann eine in Bohrrichtung gerichtete Vibrations- oder Schwingungsbewegung, welche von dem Schwingungsantrieb 30 erzeugt wird, auf das zweite Kupplungsstück und hiervon auf das erste Kupplungsstück der Drehkupplung 40 übertragen werden. Vom ersten Kupplungsstück wird diese Vibrations- oder Schwingungsbewegung aufgrund der axial festen Verbindung des ersten Kupplungsstücks zum hinteren Verbindungsende 26 der Bohrantriebswelle 22 auf diese übertragen. Somit kann in dem dargestellten Betriebszustand eine vom Bohrantrieb 20 erzeugte Drehbewegung der Bohrantriebswelle 22 mit einer axial gerichteten Vibrations- oder Schwingungsbewegung kombiniert oder überlagert werden, wie durch die dargestellten Pfeile angezeigt ist.The vibratory drive 30, which in particular has a vibrator with a plurality of rotationally driven unbalance elements, comprises a front, the drill drive 20 directed clamping device 32. The clamping device 32 is in particular a collet with radially adjustable clamping claws 36. With the clamping jaws 36 of the clamping device 32, the second coupling piece frictionally and / or positively detected. In this way, a direction of drilling directed vibration or vibration movement, which is generated by the vibration drive 30, are transmitted to the second coupling piece and thereof to the first coupling piece of the rotary joint 40. From the first coupling piece, this vibration or vibration movement is transmitted to the latter due to the axially fixed connection of the first coupling piece to the rear connection end 26 of the drill drive shaft 22. Thus, in the illustrated operating condition, a rotary motion of the drill drive shaft 22 generated by the drill drive 20 may be combined or superimposed with an axially directed vibration or oscillatory motion, as indicated by the illustrated arrows.

Über nicht dargestellte Dämpfungselemente, welche zwischen dem Gehäuse des Schwingungsantriebs 30 und dem Schwingungsantriebsschlitten 34 angeordnet sind, kann eine unmittelbare Übertragung von Schwingungen von dem Schwingungsantrieb 30 auf den Mast 12 verhindert oder zumindest weitgehend reduziert werden. Eine entsprechende Dämpfung kann auch zwischen dem Gehäuse des Bohrantriebs 20 und dem Bohrantriebsschlitten 24 angeordnet sein.Not shown damping elements, which are arranged between the housing of the vibration drive 30 and the vibration drive slide 34, a direct transmission of vibrations from the vibration drive 30 can be prevented on the mast 12 or at least largely reduced. A corresponding damping can also be arranged between the housing of the drill drive 20 and the drill drive carriage 24.

Wird für den Bohrbetrieb keine Überlagerung einer Vibrations- oder Schwingungsbewegung benötigt, kann die Spanneinrichtung 32 gelöst werden. Hierbei werden die Spannklauen 36 radial nach außen verfahren, wobei die Verbindung zur Drehkupplung 40 gelöst wird. In dieser gelösten Position kann nunmehr der Schwingungsantrieb 30 über einen nicht dargestellten Verstellantrieb entlang des Mastes 12 nach hinten verfahren und so vom Bohrantrieb 20 beabstandet werden. In umgekehrter Weise können dann auch wieder durch ein Zueinanderfahren von Bohrantrieb 20 und Schwingungsantrieb 30 die beiden Antriebe kombiniert werden. Die so gebildete Einheit aus Bohrantrieb 20 und Schwingungsantrieb 30 kann dann einheitlich entlang des Mastes 12 verfahren werden.If no superimposition of a vibration or vibration movement is required for the drilling operation, the tensioning device 32 can be released. Here, the clamping jaws 36 are moved radially outward, wherein the connection to the rotary joint 40 is solved. In this disengaged position, the oscillating drive 30 can now be moved back along the mast 12 via an adjusting drive, not shown, and thus be spaced from the drilling drive 20. In the reverse manner, the two drives can then also be combined again by moving the drill drive 20 and the vibration drive 30 together. The thus formed unit of drill drive 20 and vibration drive 30 can then be moved uniformly along the mast 12.

Die lösbare Anordnung des Schwingungsantriebs 30 erlaubt es gemäß der Erfindung, dass auch bestehende Bohrvorrichtungen 10 nachträglich mit einem Schwingungsantrieb (30) versehen werden können.The detachable arrangement of the vibration drive 30 allows according to the invention that even existing drilling devices 10 can be subsequently provided with a vibration drive (30).
