Description

Die Erfindung richtet sich auf eine Bohrvorrichtung, aufweisend einen Führungsrahmen, einen Führungstisch, welcher an dem Führungsrahmen in eine Längsrichtung des Führungsrahmens bewegbar gelagert ist, und einen auf dem Führungstisch befestigten Bohrantrieb, welcher einen motorisch angetriebenen Spannkopf zum rotatorischen Antreiben eines Bohrgestänges und eine Gestänge-Durchführung, welche ein Hindurchziehen eines von dem Spannkopf freigegebenen Bohrgestänges durch den Bohrantrieb hindurch ermöglicht.The invention relates to a drilling device, comprising a guide frame, a guide table which is movably mounted on the guide frame in a longitudinal direction of the guide frame, and a drill drive fastened on the guide table, which has a motor-driven clamping head for rotating a drill rod and a rod assembly. Implementation which enables a drill pipe released by the clamping head to be pulled through the drill drive.

Eine Bohrvorrichtung der vorstehend beschriebenen Art ist aus dem Stand der Technik bekannt und wird beispielsweise zur Durchführung von Kernbohrungen mit geeignetem Bohrgestänge eingesetzt. Bei sehr tiefen Kernbohrungen werden mehrere Bohrgestänge miteinander verbunden und bilden einen Bohrstrang. Von Nachteil bei dieser bekannten Bohrvorrichtung ist es, dass sich ein Austausch eines defekten Bohrkopfes sehr zeitaufwendig gestaltet, da aufgrund des begrenzten Verfahrweges des Führungstisches der aus mehreren Bohrgestängen bestehende Bohrstrang nur schubweise für jedes einzelne Bohrgestänge aus dem Bohrloch von der Bohrvorrichtung herausgezogen werden kann. Das Einführen des Bohrstranges nach dem Austausch des defekten Bohrkopfes gestaltet sich aufgrund des begrenzten Verfahrweges des Führungstisches ebenfalls sehr zeitaufwendig. Darüber hinaus können solche Bohrvorrichtungen nur begrenzt zur Vermessung von Bohrlöchern eingesetzt werden. Denn aufgrund des begrenzten Verfahrweges des Führungstisches und aufgrund der üblicherweise zu geringen Verfahrgeschwindigkeit des Führungstisches eignen sich die bekannten Bohrvorrichtungen kaum für beispielsweise Radarmessungen, da die Aufzeichnungsgeschwindigkeit unzureichend ist, um räumliche Strukturinformationen zur Geologie und Tektonik der Gesteine zu gewinnen.A drilling device of the type described above is known from the prior art and is used, for example, to carry out core drilling with a suitable drill string. In the case of very deep core bores, several drill pipes are connected to one another and form a drill string. The disadvantage of this known drilling device is that an exchange of a defective drill head is very time-consuming, since, due to the limited travel path of the guide table, the drill string consisting of several drill rods can only be pulled out of the drill hole in batches for each individual drill rod. The insertion of the drill string after replacing the defective drill head is also very time-consuming due to the limited travel path of the guide table. In addition, such drilling devices can only be used to a limited extent for measuring boreholes. Because of the limited travel path of the guide table and the usually too low travel speed of the guide table, the known drilling devices are hardly suitable for radar measurements, for example, since the recording speed is insufficient to obtain spatial structural information on the geology and tectonics of the rocks.

Der Erfindung liegt die Aufgabe zugrunde eine Lösung zu schaffen, die auf konstruktiv einfache Weise eine verbesserte Bohrvorrichtung bereitstellt, mit welcher eine Vielzahl von zu einem Bohrstrang miteinander verbundenen Bohrgestängen zeitlich schnell und kontinuierlich aus dem Bohrloch herausgezogen oder in das Bohrloch eingeführt werden können und mit welcher eine kontinuierliche und für eine Vermessung der Gesteine geeignete Verfahrgeschwindigkeit des Bohrstrangs realisierbar ist.The invention has for its object to provide a solution which provides an improved drilling device in a structurally simple manner, with which a plurality of drill rods connected to one another in a drill string can be quickly and continuously pulled out of the borehole or inserted into the borehole and with which a continuous traverse speed of the drill string which is suitable for measuring the rocks can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Gestänge-Schubeinrichtung an dem Führungsrahmen befestigt ist, welche mit dem Bohrgestänge kraftschlüssig verbindbar und das Bohrgestänge in Längsrichtung des Führungsrahmens bewegend ausgebildet ist.This object is achieved according to the invention in that a rod pushing device is fastened to the guide frame, which is non-positively connected to the drill rod and the drill rod is designed to move in the longitudinal direction of the guide frame.

Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous and expedient refinements and developments of the invention result from the subclaims.

Durch die Erfindung wird eine Bohrvorrichtung zur Verfügung gestellt, welche sich durch eine einfache und kostengünstige Konstruktion auszeichnet. Durch das erfindungsgemäße Bauteil der Gestänge-Schubeinrichtung ist es im Unterscheid zum Stand der Technik nun möglich, innerhalb kürzester Zeit einen aus mehreren Bohrgestängen bestehenden Bohrstrang in ein Bohrloch einzuführen oder aus einem Bohrloch zu bergen. Die Gestänge-Schubeinrichtung stellt eine zusätzliche Funktionseinheit an der Bohrvorrichtung dar und ist so konzipiert, dass gewisse Funktionen an der Bohrvorrichtung, wie zum Beispiel das Drehen des Bohrstranges mit Hilfe des Spannkopfes und das Ver- und Endschrauben von Gewindeverbindungen der Bohrgestänge, weiterhin gefahren werden können und dass die Gestänge-Schubeinrichtung an vorhandene Bohrvorrichtungen im Bereich des Führungsrahmens adaptiert werden kann. Folglich können vorhandene Bohrvorrichtungen mit der erfindungsgemäßen Gestänge-Schubeinrichtung nachgerüstet werden. Dabei liefert die kraftschlüssige Verbindung einen ausreichenden Reibungswert, um lange Bohrstränge für sehr tiefe Bohrungen zu transportieren.The invention provides a drilling device which is characterized by a simple and inexpensive construction. In contrast to the prior art, the component according to the invention of the rod thrust device makes it possible to insert a drill string consisting of several drill rods into a borehole or to recover it from a borehole within a very short time. The drill push device represents an additional functional unit on the drilling device and is designed so that certain functions on the drilling device, such as turning the drill string with the help of the clamping head and screwing and unthreading threaded connections of the drill pipe, can still be performed and that the linkage pusher can be adapted to existing drilling devices in the area of the guide frame. Consequently, existing drilling devices can be retrofitted with the rod thrust device according to the invention. The frictional connection provides one sufficient friction value to transport long drill strings for very deep holes.

Ein Verstellmechanismus sorgt dafür, dass trotz der Gestänge-Schubeinrichtung die herkömmlichen Funktionen an der Bohrvorrichtung gefahren werden können. Zu diesem Zweck sieht die Erfindung in Ausgestaltung vor, dass die Gestänge-Schubeinrichtung wenigstens einen Antriebsmotor und wenigstens ein Paar von Transportrollen aufweist, von denen mindestens eine Transportrolle mit dem wenigstens einen Antriebsmotor antriebsverbunden ist, wobei wenigstens eine Transportrolle des wenigstens einen Paares von Transportrollen auf die andere Transportrolle des wenigstens einen Paares von Transportrollen zu bewegbar oder von der anderen Transportrolle des wenigstens einen Paares von Transportrollen weg bewegbar gelagert ist, wobei das wenigstens eine Paar von Transportrollen das Bohrgestänge zwischen sich kraftschlüssig einspannend oder freigeben ausgebildet ist.An adjustment mechanism ensures that the conventional functions on the drilling device can be operated despite the linkage pushing device. For this purpose, the invention provides in an embodiment that the linkage thrust device has at least one drive motor and at least one pair of transport rollers, of which at least one transport roller is drive-connected to the at least one drive motor, at least one transport roller of the at least one pair of transport rollers the other transport roller of the at least one pair of transport rollers is movable or is mounted such that it can be moved away from the other transport roller of the at least one pair of transport rollers, the at least one pair of transport rollers being designed to clamp or release the drill pipe between them in a force-locking manner.

Dabei ist es für den zuvor genannten Verstellmechanismus von Vorteil, wenn in Ausgestaltung der Erfindung die Gestänge-Schubeinrichtung wenigstens eine Druckkonsole aufweist, welche quer zur Längsrichtung des Führungsrahmens bewegbar ausgebildet ist und an welcher eine Transportrolle des wenigstens einen Paares von Transportrollen drehbar gelagert ist. Die wenigstens eine Druckkonsole kann beispielsweise mit Hilfe eines hydraulisch betriebenen Andruckzylinders quer zur Längsrichtung des Führungsrahmens bewegt werden.It is advantageous for the aforementioned adjustment mechanism if, in an embodiment of the invention, the linkage thrust device has at least one pressure bracket which is designed to be movable transversely to the longitudinal direction of the guide frame and on which a transport roller of the at least one pair of transport rollers is rotatably mounted.

Die Erfindung sieht in weiterer Ausgestaltung vor, dass die Gestänge-Schubeinrichtung wenigstens ein Paar von Führungsrollen aufweist, wobei wenigstens eine Führungsrolle des wenigstens einen Paares von Führungsrollen auf die andere Führungsrolle des wenigstens einen Paares von Führungsrollen zu bewegbar oder von der anderen Führungsrolle des wenigstens einen Paares von Führungsrollen weg bewegbar gelagert ist, wobei das wenigstens eine Paar von Führungsrollen das Bohrgestänge zwischen sich führend ausgebildet ist. Die Führungsrollen unterstützen folglich eine genaue Führung eines von der Gestänge-Schubeinrichtung transportierten Bohrstranges und richten den Bohrstrang in Richtung des Bohrlochs und der Bohrachse aus, damit zum Transport des Bohrstranges keine unnötige Energie aufgebracht werden muss.In a further embodiment, the invention provides that the linkage pushing device has at least one pair of guide rollers, at least one guide roller of the at least one pair of guide rollers being movable toward the other guide roller of the at least one pair of guide rollers or from the other guide roller of the at least one A pair of guide rollers is mounted so that it can move away, the at least one pair of guide rollers holding the drill pipe between them is a leader. The guide rollers consequently support an exact guidance of a drill string transported by the rod pushing device and align the drill string in the direction of the borehole and the drill axis, so that no unnecessary energy has to be applied to transport the drill string.

Dabei ist es in Ausgestaltung der Erfindung von Vorteil, wenn die Gestänge-Schubeinrichtung wenigstens ein Druckstück aufweist, welches quer zur Längsrichtung des Führungsrahmens bewegbar ausgebildet ist und an welcher eine Führungsrolle des wenigstens einen Paares von Führungsrollen drehbar gelagert ist.It is advantageous in an embodiment of the invention if the linkage pushing device has at least one pressure piece which is designed to be movable transversely to the longitudinal direction of the guide frame and on which a guide roller of the at least one pair of guide rollers is rotatably mounted.

Zur Bewegung des wenigstens einen Druckstücks sieht die Erfindung in weiterer Ausgestaltung vor, dass die Gestänge-Schubeinrichtung wenigstens ein mechanisches Druckelement aufweist, welches eine das wenigstens eine Druckstück quer zur Längsrichtung des Führungsrahmens drängende und die Führungsrollen aufeinander zu bewegende Druckkraft ausübt. Konstruktiv besonders günstig ist es dabei, wenn das Druckelement als ein Federelement ausgeführt ist.To move the at least one pressure piece, the invention provides in a further embodiment that the linkage thrust device has at least one mechanical pressure element, which exerts a pressure force which pushes the at least one pressure piece transversely to the longitudinal direction of the guide frame and moves the guide rollers towards one another. It is structurally particularly favorable if the pressure element is designed as a spring element.

Damit beim Freigeben das Bohrgestänge durch das wenigstens eine Paar von Transportrollen auch das wenigstens eine Paar von Führungsrollen das Bohrgestänge freigibt, ist in weiterer Ausgestaltung der Erfindung vorgesehen, dass die wenigstens eine Druckkonsole einen Mitnehmer aufweist, welcher an einem an dem wenigstens einen Druckstück ausgebildeten Kopplungsansatz derart anliegt, dass der Mitnehmer zur Freigabe des Bohrgestänges bei einer Bewegung der Transportrollen voneinander weg gegen die Druckkraft des wenigstens einen mechanischen Druckelements die Führungsrollen voneinander wegbewegend ausgebildet ist. Auf diese Weise üben die Führungsrollen lediglich dann eine den Bohrstrang führende Funktion aus, wenn die Transportrollen den Bohrstrang kraftschlüssig einspannen.So that when the drill rod is released by the at least one pair of transport rollers, the at least one pair of guide rollers also releases the drill rod, it is provided in a further embodiment of the invention that the at least one pressure bracket has a driver which is attached to a coupling attachment formed on the at least one pressure piece bears in such a way that the driver for releasing the drill pipe is designed to move the guide rollers away from one another against the pressure force of the at least one mechanical pressure element when the transport rollers move away from one another. In this way, the guide rollers only perform a function guiding the drill string when the transport rollers clamp the drill string in a force-locking manner.

Die Erfindung sieht in weiterer Ausgestaltung der Bohrvorrichtung vor, dass die Gestänge-Schubeinrichtung einen Abstandshalter aufweist, welcher zwischen dem wenigstens einen Paar von Führungsrollen und parallel zu einer Bohrachse des Bohrgestänges angeordnet ist und welcher eine Bewegung des wenigstens einen Druckstücks über die Bohrachse hinweg blockiert. Die Bohrachse entspricht dabei der Richtung, in welche der Bohrstrang von der Gestänge-Schubeinrichtung transportiert wird.In a further embodiment of the drilling device, the invention provides that the rod pushing device unites Spacer, which is arranged between the at least one pair of guide rollers and parallel to a drilling axis of the drill pipe and which blocks a movement of the at least one pressure piece over the drilling axis. The drilling axis corresponds to the direction in which the drill string is transported by the drill pushing device.

In weiterer Ausgestaltung der Erfindung ist dann vorgesehen, dass eine Gestänge-Abfangvorrichtung mit einer Einspannvorrichtung an dem Führungsrahmen befestigt ist, wobei das Bohrgestänge mit Hilfe der Einspannvorrichtung einspannbar ist. Die Gestänge-Abfangvorrichtung dient unter anderem dem Zweck, den Bohrstrang beim Bohrvorgang festzuhalten, wenn ein neues Bohrgestänge mit dem Bohrstrang verbunden wird, um das Bohrloch tiefer voranzutreiben.In a further embodiment of the invention it is then provided that a rod catch device is fastened to the guide frame with a clamping device, the drill rod being clampable with the aid of the clamping device. One of the purposes of the drill string intercept device is to hold the drill string in place during the drilling process when a new drill pipe is connected to the drill string in order to drive the borehole deeper.

Ferner sieht die Erfindung in Ausgestaltung vor, dass der Bohrantrieb zwischen der Gestänge-Abfangvorrichtung und der Gestänge-Schubeinrichtung angeordnet ist. Aus Richtung eines Bohrlochs betrachtet ist die Gestänge-Schubeinrichtung damit hinter dem Bohrantrieb angeordnet.Furthermore, the invention provides in an embodiment that the drill drive is arranged between the rod interception device and the rod thrust device. Viewed from the direction of a borehole, the rod pushing device is thus arranged behind the drill drive.

Zum Auseinanderbau des aus mehreren Bohrgestängen bestehenden Bohrstrangs sieht die Erfindung in weiterer Ausgestaltung vor, dass zwischen der Gestänge-Abfangvorrichtung und dem Bohrantrieb eine Gestänge-Brecheinrichtung angeordnet ist. Wenn die Gestänge-Abfangvorrichtung den Bohrstrang fixiert und die Spanneinrichtung sowie die Gestänge-Schubeinrichtung den Bohrstrang freigeben, so kann die Gestänge-Brecheinrichtung den Bohrstrang ebenfalls fixieren und dabei um 20° bis 30° um die Bohrachse drehen, um eine Gewindeverbindung zwischen zwei Bohrgestängen zu lösen, wenn die Gewindeverbindung zwischen der Gestänge-Abfangvorrichtung und der Gestänge-Brecheinrichtung angeordnet ist.In order to disassemble the drill string consisting of several drill rods, the invention provides in a further embodiment that a rod breaking device is arranged between the rod intercepting device and the drill drive. If the rod interception device fixes the drill string and the tensioning device as well as the rod pushing device release the drill string, the rod breaking device can also fix the drill string and thereby turn 20 ° to 30 ° around the drill axis in order to create a threaded connection between two drill rods loosen when the threaded connection between the boom interceptor and the boom breaker is arranged.

Schließlich ist in Ausgestaltung der Erfindung vorgesehen, dass der Spannkopf als eine Hohlspindel ausgebildet ist. Bei einer solchen Ausgestaltung kann das Bohrgestänge an einer beliebigen Stelle umfassend schonend eingespannt werden. Zudem ist beim Ein- und Ausbau des Bohrgestänges ein Durchziehen des Bohrgestänges durch den Bohrantrieb möglich, wodurch sich besonders der Ein- und Ausbau langer Bohrstränge vereinfacht.Finally, it is provided in an embodiment of the invention that the clamping head is designed as a hollow spindle. at In such an embodiment, the drill pipe can be clamped in at any point in a comprehensive and gentle manner. In addition, pulling the drill pipe through the drill drive is possible when installing and removing the drill pipe, which in particular simplifies the installation and removal of long drill pipes.

In Figur 1 ist eine erfindungsgemäße Bohrvorrichtung 1 in perspektivischer Ansicht dargestellt. Die Bohrvorrichtung 1 wird beispielsweise zur Durchführung von Kernbohrungen oder zur Vermessung eingesetzt, wobei dazu jeweils ein geeignetes Bohrgestänge 2 eingesetzt wird. In Figur 1 sind zwei Bohrgestänge 2 exemplarisch dargestellt, wobei mehrere Bohrgestänge 2 über jeweilige Gewindeverbindungen zu einem langen Bohrstrang für sehr tiefe Kernbohrungen miteinander verbunden werden können. Die erfindungsgemäße Bohrvorrichtung 1 weist einen Führungsrahmen 3 und einen Führungstisch 4 auf, wobei der Führungstisch 4 an dem Führungsrahmen 3 in eine Längsrichtung 5 des Führungsrahmens 3 bewegbar gelagert ist. Ferner weist die Bohrvorrichtung 1 einen Bohrantrieb 6, eine Gestänge-Abfangvorrichtung 7, eine Gestänge-Brecheinrichtung 8 und eine Gestänge-Schubeinrichtung 9 auf. Die Bohrvorrichtung 1 ist auf einem Transportrahmen 10 angeordnet, wobei drei Hubzylinder 11 dazu dienen, den Transportrahmen 10 auszurichten. Eine mechanische Stütze 12 und Hydraulikzylinder 14 sind an dem Transportrahmen 10 angebracht, wobei über die mechanische Stütze 12 und die Hydraulikzylinder 14 die Bohrvorrichtung 1 in einem gewünschten Bohrwinkel positioniert werden kann. An dem Führungsrahmen 3 ist ferner eine Förderrinne 15 angebracht, die zur Aufnahme der bei Kernbohrungen gewonnenen Kerne dient.In Figure 1 A drilling device 1 according to the invention is shown in perspective view. The drilling device 1 is used, for example, to carry out core bores or to measure, a suitable drill rod 2 being used for this purpose. In Figure 1 Two drill rods 2 are shown by way of example, it being possible for a plurality of drill rods 2 to be connected to one another via respective threaded connections to form a long drill string for very deep core bores. The drilling device 1 according to the invention has a guide frame 3 and a guide table 4, the guide table 4 being movably mounted on the guide frame 3 in a longitudinal direction 5 of the guide frame 3. Furthermore, the drilling device 1 has a drilling drive 6, a rod interception device 7, a rod breaking device 8 and a rod thrust device 9. The drilling device 1 is arranged on a transport frame 10, with three lifting cylinders 11 serving to align the transport frame 10. A mechanical support 12 and hydraulic cylinder 14 are attached to the transport frame 10, wherein the drilling device 1 can be positioned at a desired drilling angle via the mechanical support 12 and the hydraulic cylinder 14. A conveyor trough 15 is also attached to the guide frame 3 and serves to receive the cores obtained from core drilling.

Der Bohrantrieb 6 ist auf dem Führungstisch 4 befestigt und weist einen motorisch angetriebenen Spannkopf zum rotatorischen Antreiben des Bohrgestänges 2 und eine Gestänge-Durchführung 19 auf, die ansatzweise in Figur 2 gezeigt ist. Die Gestänge-Durchführung 19 ermöglicht ein Hindurchziehen eines von dem Spannkopf freigegebenen Bohrgestänges 2 durch den Bohrantrieb 6 hindurch, wobei zu diesem Zweck der Spannkopf als eine Hohlspindel ausgebildet ist. Der Bohrantrieb 6 umfasst ferner ein Stirnradgetriebe und einen Hydraulikmotor, welche in den Figuren nicht näher dargestellt sind, da sie aus dem Stand der Technik bekannt sind.The drill drive 6 is fastened on the guide table 4 and has a motor-driven clamping head for rotating the drill rod 2 and a rod bushing 19, which is partially in FIG Figure 2 is shown. The rod bushing 19 enables a drill rod 2 released by the clamping head to be pulled through the drilling drive 6, the clamping head being designed as a hollow spindle for this purpose. The drill drive 6 further comprises a spur gear and a hydraulic motor, which are not shown in the figures, since they are known from the prior art.

Die Gestänge-Abfangvorrichtung 7 und die Gestänge-Brecheinrichtung 8 sind an dem Führungsrahmen 3 befestigt und in den Figuren 3 bis 5 näher dargestellt, wobei die Gestänge-Brecheinrichtung 8 zwischen dem Bohrantrieb 6 und der Gestänge-Abfangvorrichtung 7 angeordnet ist. Die Gestänge-Abfangvorrichtung 7 weist Führungsrollen 16, welche zur Führung des Bohrgestänges 2 beim Bohren dienen und von denen in Figur 4 lediglich drei der vier Führungsrollen 16 zu erkennen sind, und eine Einspannvorrichtung 17 (siehe zum Beispiel Figur 4) auf, die zum Festklemmen des Bohrgestänges 2 dient, wobei die Einspannvorrichtung 17 beim Bohren nicht in Betrieb ist, sondern das Bohrgestänge 2 freigibt. Demgegenüber weist die Gestänge-Brecheinrichtung 8 um eine Bohrachse 32 drehbare Klemmstücke 18 auf, welche beispielsweise zum Lösen einer Gewindeverbindung zwischen zwei Bohrgestängen 2 dient, indem die Einspannvorrichtung 17 der Gestänge-Abfangvorrichtung 7 ein erstes Bohrgestänge 2 festklemmt, die Klemmstücke 18 der Gestänge-Brechvorrichtung 8 ein zweites Bohrgestänge 2, welches über eine Gewindeverbindung mit dem ersten Bohrgestänge 2 verbunden ist, festklemmen und die Klemmstücke 18 relativ zu der Einspannvorrichtung 17 um die Bohrachse 32 gedreht werden, um die zwischen der Gestänge-Abfangvorrichtung 7 und der Gestänge-Brechvorrichtung 8 angeordnete Gewindeverbindung der beiden Bohrgestänge 2 zu lösen.The linkage interception device 7 and the linkage breaking device 8 are attached to the guide frame 3 and in the Figures 3 to 5 shown in more detail, the linkage breaking device 8 being arranged between the drill drive 6 and the linkage interception device 7. The rod interception device 7 has guide rollers 16 which serve to guide the drill rod 2 during drilling and of which in Figure 4 only three of the four guide rollers 16 can be seen, and a clamping device 17 (see for example Figure 4 ), which serves to clamp the drill pipe 2, the clamping device 17 not being in operation during drilling, but releasing the drill pipe 2. In contrast, the rod breaking device 8 has clamping pieces 18 which can be rotated about a drilling axis 32 and which, for example, serves to loosen a threaded connection between two drill rods 2 by the clamping device 17 of the rod catching device 7 clamping a first drill rod 2, the clamping pieces 18 of the rod breaking device 8 clamp a second drill pipe 2, which is connected to the first drill pipe 2 via a threaded connection, and the clamping pieces 18 are rotated relative to the clamping device 17 about the drilling axis 32, around the one arranged between the pipe catcher 7 and the pipe breaking device 8 Loosen the threaded connection of the two drill rods 2.

Wie aus Figur 1 ersichtlich ist, ist der Bohrantrieb 6 zwischen der Gestänge-Abfangvorrichtung 7 und der Gestänge-Schubeinrichtung 9 angeordnet, wobei die Gestänge-Schubeinrichtung 9 an einer Verlängerung des Führungsrahmens 3 befestigt ist und zwischen der Förderrinne 15 und dem Bohrantrieb 6 angeordnet ist. Die Gestänge-Schubeinrichtung 9 ist in den Figuren 6 bis 8 näher dargestellt und ist mit dem Bohrgestänge 2 kraftschlüssig verbindbar, wobei die Gestänge-Schubeinrichtung 9 das Bohrgestänge 2 in Längsrichtung 5 des Führungsrahmens 3 bewegend ausgebildet ist. Die Gestänge-Schubeinrichtung 9 weist eine Stützkonsole 20, über welche die Gestänge-Schubeinrichtung 9 an der Verlängerung des Führungsrahmens 3 befestigt ist, und ein Gehäuse 21 auf. In dem dargestellten Ausführungsbeispiel sind auf dem Gehäuse 21 zwei Antriebsmotoren 22a, 22b angeordnet (siehe Figur 6), wobei jeder der beiden Antriebsmotoren 22a bzw. 22b jeweils mit einer Transportrolle 23a bzw. 23b eines Paares von Transportrollen 23a, 23b antriebsverbunden ist. Die beiden Transportrollen 23a und 23b sind jeweils nach innen gewölbt, d.h. konkav, ausgebildet, so dass die Transportrollen 23a und 23b das Bohrgestänge 2 sicher zwischen sich erfassen (siehe zum Beispiel Figur 7). Es versteht sich, dass für eine alternative Ausgestaltung nur ein Antriebsmotor vorgesehen sein kann, der entweder mit beiden Transportrollen 23a und 23b oder nur mit einer der beiden Transportrollen 23a oder 23b antriebsverbunden ist. Die Gestänge-Schubeinrichtung 9 ist nur im Betrieb, um einen aus mehreren Bohrgestängen 2 bestehenden Bohrstrang aus einem Bohrloch oder in ein Bohrloch hinein zu transportieren, wobei dies bei einem Austausch eines defekten Bohrkopfes oder zu Messzwecken der Fall ist. Aus diesem Grund sind die Transportrollen 23a und 23b bewegbar gelagert, wobei die beiden Transportrollen 23a, 23b aufeinander zu (um den Bohrstrang einzuspannen) oder voneinander weg (um den Bohrstrang freizugeben) bewegbar gelagert sind. Alternativ ist es auch denkbar, dass nur eine Transportrolle 23a oder 23b quer zur Längsrichtung 5 des Führungsrahmens 3 bewegbar gelagert ist, so dass eine Transportrolle 23a oder 23b des Paares von Transportrollen 23a, 23b auf die andere Transportrolle 23a oder 23b des Paares von Transportrollen 23a, 23b zu bewegbar oder von der anderen Transportrolle 23a oder 23b des Paares von Transportrollen 23a, 23b weg bewegbar gelagert ist. Durch die Bewegbarkeit wenigstens einer der beiden Transportrollen 23a, 23b ist es möglich, dass das Paar von Transportrollen 23a, 23b das Bohrgestänge 2 zwischen sich kraftschlüssig einspannt oder freigibt, wobei beim Einspannen die Transportrollen 23a, 23b mit einer entsprechenden Radialkraft beaufschlagt werden, so dass ein ausreichend großer Reibwert entsteht, um lange Bohrstränge zu transportieren. Die Bewegbarkeit der in dem Ausführungsbeispiel gezeigten Transportrollen 23a oder 23 ist dadurch realisiert, dass die Gestänge-Schubeinrichtung 9 zwei Druckkonsolen 24a und 24b aufweist, wobei aus Gründen der Übersichtlichkeit in Figur 8 die Druckkonsolen 24a und 24b nicht gezeigt sind. Jede einzelne Druckkonsole 24a, 24b ist quer zur Längsrichtung 15 des Führungsrahmens 3 bewegbar, wobei an jeder Druckkonsole 24a, 24b jeweils eine Transportrolle 23a, 23b drehbar gelagert ist und von dem zugewiesenen Antriebsmotor 22a, 22b angetrieben werden kann. Jede Druckkonsole 24a, 24b ist jeweils mit Hilfe eines hydraulisch betriebenen Andruckzylinders 25a, 25b antriebsverbunden und bewegbar im Gehäuse 21 gelagert, wobei ein jeweiliger Andruckzylinder 25a, 25b eine zugeordnete Druckkonsole 24a, 24b in eine auf die andere Druckkonsole 24a, 24b hin oder von der anderen Druckkonsole 24a, 24b weg gerichtete Richtung bewegt.How from Figure 1 it can be seen that the drill drive 6 is arranged between the rod interception device 7 and the rod thrust device 9, the rod thrust device 9 being fastened to an extension of the guide frame 3 and being arranged between the conveyor trough 15 and the drill drive 6. The linkage pusher 9 is in the Figures 6 to 8 Shown in more detail and can be non-positively connected to the drill pipe 2, the drill pushing device 9 being designed to move the drill pipe 2 in the longitudinal direction 5 of the guide frame 3. The linkage pusher 9 has a support bracket 20, via which the linkage pushing device 9 is fastened to the extension of the guide frame 3, and a housing 21. In the exemplary embodiment shown, two drive motors 22a, 22b are arranged on the housing 21 (see Figure 6 ), each of the two drive motors 22a and 22b being drive-connected to a transport roller 23a or 23b of a pair of transport rollers 23a, 23b. The two transport rollers 23a and 23b are each curved inwards, ie concave, so that the transport rollers 23a and 23b securely grasp the drill pipe 2 between them (see for example Figure 7 ). It goes without saying that, for an alternative embodiment, only one drive motor can be provided, which is either drive-connected to both transport rollers 23a and 23b or only to one of the two transport rollers 23a or 23b. The rod pushing device 9 is only in operation in order to transport a drill string consisting of several drill rods 2 from a borehole or into a borehole, this being the case when a defective drill head is replaced or for measuring purposes. For this reason, the transport rollers 23a and 23b are movably mounted, the two transport rollers 23a, 23b being movably mounted towards one another (in order to clamp the drill string) or away from one another (in order to release the drill string). Alternatively, it is also conceivable that only one transport roller 23a or 23b is movably mounted transversely to the longitudinal direction 5 of the guide frame 3, so that one transport roller 23a or 23b of the pair of transport rollers 23a, 23b onto the other transport roller 23a or 23b of the pair of transport rollers 23a , 23b to be movable or mounted to be movable away from the other transport roller 23a or 23b of the pair of transport rollers 23a, 23b. Due to the mobility of at least one of the two transport rollers 23a, 23b, it is possible for the pair of transport rollers 23a, 23b to clamp or clamp the drill pipe 2 between them releases, the transport rollers 23a, 23b being acted upon by a corresponding radial force during clamping, so that a sufficiently high coefficient of friction arises to transport long drill strings. The mobility of the transport rollers 23a or 23 shown in the exemplary embodiment is realized in that the linkage thrust device 9 has two pressure brackets 24a and 24b, with the sake of clarity in Figure 8 the print consoles 24a and 24b are not shown. Each individual pressure bracket 24a, 24b can be moved transversely to the longitudinal direction 15 of the guide frame 3, wherein a transport roller 23a, 23b is rotatably mounted on each pressure bracket 24a, 24b and can be driven by the assigned drive motor 22a, 22b. Each pressure bracket 24a, 24b is connected to the drive with the aid of a hydraulically operated pressure cylinder 25a, 25b and is movably mounted in the housing 21, a respective pressure cylinder 25a, 25b assigning an associated pressure bracket 24a, 24b into or from the other pressure bracket 24a, 24b other pressure console 24a, 24b moved away direction.

Wie den Figuren 6 bis 8 ferner zu entnehmen ist, weist die Gestänge-Schubeinrichtung 9 ein Paar von Führungsrollen 26a und 26b auf, welche drehbar an der Gestänge-Schubeinrichtung 9 gelagert und das Bohrgestänge 2 zwischen sich führend ausgebildet sind. Die Führungsrollen 26a, 26b sind wie die Transportrollen 23a, 23b aufeinander zu bewegbar gelagert, wobei es alternativ auch denkbar ist, dass nur eine Führungsrolle 26a oder 26b zu der anderen Führungsrolle 26a oder 26b hin oder von der anderen Führungsrolle 26a oder 26b weg bewegbar gelagert ist. Für die Führungsrollen 26a, 26b wird die Beweglichkeit quer zur Längsrichtung 5 des Führungsrahmens mit Hilfe von Druckstücken 27a, 27b realisiert. Die Druckstücke 27a und 27b sind quer zur Längsrichtung 5 des Führungsrahmens 3 bewegbar gelagert, wobei an jedem Druckstück 27a, 27b eine der Führungsrollen 26a, 26b des Paares von Führungsrollen 26a, 26b drehbar gelagert ist. Dabei ist jedem Druckstück 27a, 27b ein mechanisches Druckelement 28a, 28b (siehe Figur 8) zugewiesen, welches jeweils in Form einer Druckfeder ausgebildet ist und innerhalb einer zu dem Gehäuse 21 hin offenen Abdeckung angeordnet ist. Ein jeweiliges Druckelement 28a, 28b übt eine das zugeordnete Druckstück 27a, 27b quer zur Längsrichtung 5 des Führungsrahmens 3 drängende und die Führungsrollen 26a, 26b aufeinander zu bewegende Druckkraft aus. Damit die beiden Druckelemente 28a, 28b die Druckstücke 27a, 27b nicht dauerhaft mit dieser Druckkraft beaufschlagen und die Führungsrollen 26a, 26b in einer aufeinander zu bewegten Stellung halten, ist an jeder Druckkonsole 24a, 24b jeweils ein Mitnehmer 29a, 29b ausgebildet, wohingegen an jedem Druckstück 27a, 27b jeweils ein Kopplungsansatz 30a, 30b ausgebildet ist. Dabei liegt ein jeder der Mitnehmer 29a, 29b derart an dem ihm zugeordneten Kopplungsansatz 30a, 30b an, beim Freigeben des Bohrgestänges 2 durch die voneinander wegbewegten Transportrollen 23a, 23b auch die Führungsrollen 26a, 26b voneinander wegbewegt werden, indem die Mitnehmer 29a, 29b die Druckstücke 27a, 27b über den jeweiligen Kopplungsansatz 30a, 30b voneinander wegbewegen, wodurch sich die an dem jeweiligen Druckstück 27a, 27b drehbar gelagerten Führungsrolle 26a, 26b voneinander wegbewegen. Damit trotz erwünschter Führung durch die Führungsrollen 26a, 26b das Bohrgestänge 2 beispielsweise bei einem Einführen eines Bohrstrangs in ein sehr tiefes Bohrloch ausreichend ausgerichtet ist und nicht durch die Führungsrollen 23a, 23b fehlerhaft ausgerichtet ist, weist die Gestänge-Schubeinrichtung 9 einen Abstandshalter 31 auf, welcher dafür sorgt, dass beim Einspannen des Bohrgestänges 2 die Führungsrollen 23a, 23b in einem größeren Abstand zu dem Bohrgestänge 2 angeordnet sind als die an der entsprechenden Druckkonsole 24a, 24b gelagerten Transportrollen 23a, 23b. Der Abstandshalter 31 ist zwischen dem Paar von Führungsrollen 26a, 26b und parallel zu einer Bohrachse 32 des Bohrgestänges 2 angeordnet. Zusätzlich blockiert der Abstandshalter 31 eine Bewegung der Druckstücke 27a, 27b über die Bohrachse 32 hinweg (siehe zum Beispiel Figur 8).Like that Figures 6 to 8 can also be seen, the rod pushing device 9 has a pair of guide rollers 26a and 26b, which are rotatably mounted on the rod pushing device 9 and the drill rod 2 are designed to be guided between them. The guide rollers 26a, 26b, like the transport rollers 23a, 23b, are mounted such that they can be moved towards one another, whereby it is alternatively also conceivable that only one guide roller 26a or 26b is movably supported towards the other guide roller 26a or 26b or away from the other guide roller 26a or 26b is. For the guide rollers 26a, 26b, the mobility transverse to the longitudinal direction 5 of the guide frame is achieved with the aid of pressure pieces 27a, 27b. The pressure pieces 27a and 27b are movably mounted transversely to the longitudinal direction 5 of the guide frame 3, one of the guide rollers 26a, 26b of the pair of guide rollers 26a, 26b on each pressure piece 27a, 27b is rotatably mounted. Each pressure piece 27a, 27b has a mechanical pressure element 28a, 28b (see Figure 8 ) assigned, which is in the form of a compression spring and is arranged within a cover open to the housing 21. A respective pressure element 28a, 28b exerts a pressure force which pushes the associated pressure piece 27a, 27b transversely to the longitudinal direction 5 of the guide frame 3 and which moves the guide rollers 26a, 26b towards one another. So that the two pressure elements 28a, 28b do not permanently apply this pressure force to the pressure pieces 27a, 27b and keep the guide rollers 26a, 26b in a position that is moved towards one another, a driver 29a, 29b is formed on each pressure bracket 24a, 24b, whereas on each Pressure piece 27a, 27b each have a coupling projection 30a, 30b. Each of the carriers 29a, 29b lies against the coupling projection 30a, 30b assigned to it, when the drill pipe 2 is released by the transport rollers 23a, 23b moved away from one another, the guide rollers 26a, 26b are also moved away from one another by the carriers 29a, 29b Move thrust pieces 27a, 27b away from one another via the respective coupling projection 30a, 30b, as a result of which the guide roller 26a, 26b rotatably mounted on the respective thrust piece 27a, 27b move away from one another. So that, despite the desired guidance by the guide rollers 26a, 26b, the drill pipe 2 is adequately aligned, for example when a drill string is inserted into a very deep borehole, and is not misaligned by the guide rollers 23a, 23b, the drill rod pushing device 9 has a spacer 31, which ensures that when the drill pipe 2 is clamped in, the guide rollers 23a, 23b are arranged at a greater distance from the drill pipe 2 than the transport rollers 23a, 23b mounted on the corresponding pressure bracket 24a, 24b. The spacer 31 is arranged between the pair of guide rollers 26a, 26b and parallel to a drilling axis 32 of the drill pipe 2. In addition, the Spacer 31 a movement of the pressure pieces 27a, 27b over the drilling axis 32 (see for example Figure 8 ).

Zusammenfassend ist eine Bohrvorrichtung 1 mit einer Gestänge-Schubeinrichtung 9 vorstehend vorgestellt worden, wobei die Gestänge-Schubeinrichtung ein schnelles Einführen und Bergen von sehr langen Bohrsträngen von beispielsweise 50-100 Metern in- bzw. aus einem sehr tiefen Bohrloch ermöglicht. Die Gestänge-Schubeinrichtung 9 ist als zusätzliche Funktionseinheit an der Bohrvorrichtung 1 angebracht. Über ein oder zwei Antriebsmotoren 22a, 22b sind Transportrollen 23a, 23b angetrieben, wobei die Transportrollen 23a, 23b zum Transport eines Bohrstrangs mit einer entsprechenden Radialkraft beaufschlagt sind, so dass ein ausreichend großer Reibwert entsteht, um einen langen Bohrstrang zu transportieren. Durch die Drehbewegung der angetriebenen Transportrollen 23a, 23b wird der Bohrstrang in axialer Richtung (Längsrichtung 5 des Führungsrahmens 3) transportiert. Dabei kann über einen Drehgeber, der auf einer Achse der Transportrollen 23a, 23b befestigt ist, und eine mit dem Drehgeber verbundene Steuerung der Transportweg des Bohrgestänges gemessen und der Ausgabewert entsprechend verarbeitet werden. Zwei zusätzliche Führungsrollen 26a, 26b sorgen dafür, dass das Bohrgestänge 2 in der Bohrachse 32 der Bohrvorrichtung 1 gehalten ist.In summary, a drilling device 1 with a rod pushing device 9 has been presented above, wherein the rod pushing device enables a quick introduction and recovery of very long drill strings of, for example, 50-100 meters into or out of a very deep borehole. The rod thrust device 9 is attached to the drilling device 1 as an additional functional unit. Transport rollers 23a, 23b are driven via one or two drive motors 22a, 22b, with the transport rollers 23a, 23b being subjected to a corresponding radial force for transporting a drill string, so that a sufficiently high coefficient of friction arises to transport a long drill string. The drill string is transported in the axial direction (longitudinal direction 5 of the guide frame 3) by the rotary movement of the driven transport rollers 23a, 23b. In this case, the transport path of the drill pipe can be measured and the output value can be processed accordingly via a rotary encoder, which is attached to an axis of the transport rollers 23a, 23b, and a control connected to the rotary encoder. Two additional guide rollers 26a, 26b ensure that the drill string 2 is held in the drilling axis 32 of the drilling device 1.

Die Gestänge-Schubeinrichtung 9 ist so ausgebildet, dass der Bohrstrang immer im Zentrum der Bohrachse 32 bewegt wird. Über einen Verstellmechanismus kann der Andruck der Transportrollen 23a, 23b gelöst und auch wieder aufgebracht werden, so dass trotz angebauter Gestänge-Schubeinrichtung 9 gewisse Funktionen an der Bohrvorrichtung 1 gefahren werden können, wie zum Beispiel das Drehen des Bohrstrangs mit Hilfe eines Spannkopfes sowie das Ver- und Endschrauben der Gewindeverbindungen mit Hilfe eines Spannkopfes. Die Gestänge-Schubeinrichtung 9 ist so konzipiert, dass sie an vorhandenen Bohrvorrichtungen 1 im Bereich des Führungsrahmens 3 adaptiert werden kann.The rod thrust device 9 is designed such that the drill string is always moved in the center of the drill axis 32. The pressure of the transport rollers 23a, 23b can be released and reapplied via an adjustment mechanism, so that certain functions can be performed on the drilling device 1 despite the attached linkage pushing device 9, such as, for example, rotating the drill string with the aid of a tensioning head and ver - and end screws of the threaded connections with the help of a clamping head. The rod thrust device 9 is designed so that it can be adapted to existing drilling devices 1 in the area of the guide frame 3.
