Aufgabe der Erfindung ist es ein Bohrgerät, insbesondere ein Erd- oder Gesteinsbohrgerät, mit einer Vorrichtung zum Beschicken einer Bohreinrichtung des Bohrgerätes mit einem Doppelgestänge anzugeben, das bei kompaktem und einfachem Aufbau der Vorrichtung eine besonders hohe Zuverlässigkeit und Betriebssicherheit gewährleistet. The object of the invention is to provide a drill, in particular an earth or rock drill, with a device for feeding a drilling device of the drill with a double rod, which ensures a particularly high reliability and reliability in a compact and simple design of the device.
Die Aufgabe wird erfindungsgemäß durch ein Bohrgerät mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsbeispiele sind in den abhängigen Ansprüchen angegeben.The object is achieved by a drill with the features of
Bei der Vorrichtung zum Beschicken des erfindungsgemäßen Bohrgerätes ist vorgesehen, dass das Gestängemagazin als ein drehbares Revolvermagazin mit Doppelaufnahmen ausgebildet ist, welche jeweils ein Halteelement für ein Außenrohr und ein weiteres Halteelement für ein innerhalb des Außenrohres angeordnetes Innenrohr aufweisen.In the device for feeding the drilling device according to the invention it is provided that the rod magazine as a rotatable Revolver magazine is formed with double receptacles, which each have a holding element for an outer tube and a further holding element for an inner tube arranged within the outer tube.
Ein Grundgedanke der Erfindung kann in einer Ausbildung eines Revolvermagazins mit Doppelaufnahmen gesehen werden, die jeweils eine Lagerung eines Rohrpaares bestehend aus einem Innenrohr und einem Außenrohr am selben Platz zulassen. Erfindungsgemäß können die Innenrohre und die Außenrohre in einer ineinander gesteckten Position im Magazin gehalten werden. Die Rohre können somit in genau der Anordnung magaziniert werden, in der sie sich auch beim Doppelrohrbohren befinden. Hierdurch wird die Zahl der bei der Beschickung der Bohreinrichtung oder beim Magazinieren erforderlichen Umgreifprozesse reduziert, was einen besonders zuverlässigen Betrieb, insbesondere eine besonders einfache Manipulatorsteuerung, bei einfachem apparativem Aufbau gewährleistet. Die Betriebssicherheit, insbesondere bei der Manipulatorhandhabung, wird weiter dadurch verbessert, dass die Doppelaufnahmen nicht ortsfest sondern an einem drehbaren Revolvermagazin vorgesehen sind. Dieses Revolvermagazin ermöglicht es, die in der Bohranordnung befindlichen magazinierten Doppelgestängeschüsse stets an die selbe Übergabeposition zu verbringen, an der sie von einem Bediener gut gesehen sowie in besonders zuverlässiger Weise vom Manipulator gegriffen und in die Bohrachse verbracht werden können.A basic idea of the invention can be seen in a design of a revolver magazine with double receptacles, which each allow a bearing of a tube pair consisting of an inner tube and an outer tube in the same place. According to the invention, the inner tubes and the outer tubes can be held in a nested position in the magazine. The tubes can thus be magazined in exactly the arrangement in which they are also in the double-tube drilling. As a result, the number of Umgreifprozesse required during the loading of the drilling device or magazining is reduced, which ensures a particularly reliable operation, in particular a particularly simple manipulator control, with a simple apparatus design. The reliability, especially in manipulator handling, is further improved by the fact that the double shots are not stationary but are provided on a rotatable turret magazine. This revolver magazine makes it possible to always spend the magazinierten Doppelgestängeschüsse located in the drilling at the same transfer position where they can be well seen by an operator and used in a particularly reliable manner by the manipulator and spent in the drilling axis.
Unter einem Revolvermagazin kann insbesondere ein Magazin verstanden werden, bei dem die Aufnahmen und/oder die aufgenommenen Rohre um die Drehachse des Magazins herum angeordnet sind, wobei die Längsachsen der aufgenommenen Rohre geeigneter Weise parallel zur Drehachse verlaufen. Für einen besonders einfachen Antrieb des Magazins verläuft die Drehachse vorzugsweise mittig bezüglich der Aufnahmen, insbesondere entlang einer Mittenachse des Gestängemagazins.A revolver magazine may in particular be understood to mean a magazine in which the receptacles and / or the tubes received are arranged around the axis of rotation of the magazine, the longitudinal axes of the tubes received being suitably parallel to the axis of rotation. For a particularly simple drive of the magazine, the axis of rotation preferably runs centrally with respect to the receptacles, in particular along a center axis of the rod magazine.
Vorzugsweise sind die Aufnahmen auf einem Kreis angeordnet, dessen Mittelpunkt geeigneter Weise auf der Drehachse des Gestängemagazins liegt. Die Längsachsen der Rohre und der Aufnahmen können auf einem Zylindermantel liegen, dessen Längsachse mit der Drehachse zusammenfällt. Eine solche Anordnung als Trommelmagazin ist besonders kompakt.Preferably, the receptacles are arranged on a circle whose center is suitably on the axis of rotation of the rod magazine. The longitudinal axes of the tubes and the receptacles may lie on a cylinder jacket whose longitudinal axis coincides with the axis of rotation. Such an arrangement as a drum magazine is particularly compact.
Eine konstruktiv besonders einfache Vorrichtung ist dadurch gegeben, dass das Gestängemagazin ein zentrales Achsrohr aufweist, über welches das Gestängemagazin an zumindest einer Lagerstelle gelagert ist. Vorzugsweise ist die Lagerung über das zentrale Achsrohr zumindest auf der den Aufnahmen abgewandten Stirnseite des Gestängemagazins vorgesehen. Diese Art der Lagerung ermöglicht einen besonders einfachen Zugriff auf die magazinierten Rohre. Das Gestängemagazin kann auch mehrfach am zentralen Achsrohr gelagert sein, wobei das zentrale Achsrohr grundsätzlich auch unterbrochen sein kann. Besonders vorteilhaft ist nach der Erfindung, dass das Gestängemagazin auswechselbar in der Vorrichtung gelagert ist. Die Auswechselbarkeit des Magazins ermöglicht es, die Vorrichtung schnell und einfach auf ein anderes Gestängesystem umzurüsten.A structurally particularly simple device is given by the fact that the rod magazine has a central axle tube, via which the rod magazine on at least one bearing point is stored. Preferably, the storage is provided via the central axle tube at least on the side facing away from the receptacles end side of the rod magazine. This type of storage allows particularly easy access to the magazine tubes. The linkage magazine can also be mounted several times on the central axle tube, wherein the central axle tube can in principle also be interrupted. It is particularly advantageous according to the invention that the rod magazine is interchangeable stored in the device. The interchangeability of the magazine makes it possible to quickly and easily convert the device to another linkage system.
Vorteilhaft ist hierfür, dass zumindest eine Lagerstelle des Gestängemagazins lösbar ist. Durch lösbare Lagerstellen kann in besonders einfacher Weise ein auswechselbares Magazin geschaffen werden. Die lösbare Lagerstelle kann beispielsweise zwei oder mehr Lagerschalen aufweisen, die voneinander lösbar und wieder verschließbar sind. Insbesondere kann eine Lagerschale gegenüber einer anderen Lagerschale verschwenkbar vorgesehen werden. Hierdurch kann beispielsweise eine aufklappbare Lagerstelle geschaffen werden. Die Lagerstellen umfassen geeigneter Weise Gleit- oder Wälzlager.It is advantageous for this that at least one bearing point of the linkage magazine is detachable. By releasable bearings, a replaceable magazine can be created in a particularly simple manner. The detachable bearing point can, for example, have two or more bearing shells, which can be detached from one another and closed again. In particular, a bearing shell can be provided pivotably with respect to another bearing shell. As a result, for example, a hinged bearing point can be created. The bearings suitably include plain or roller bearings.
Ferner ist nach der Erfindung vorteilhaft, dass das Gestängemagazin mehrteilig mit einem Aufnahmeteil, an dem die Aufnahmen angeordnet sind, und einem Antriebsteil, an dem ein Magazindrehantrieb vorgesehen ist, ausgebildet ist, wobei das Aufnahmeteil insbesondere lösbar am Antriebsteil befestigt ist. Hierdurch kann ein teilbares Magazin geschaffen werden, bei dem die Aufnahmen inklusive der darin gelagerten Rohre vom Antriebsteil des Magazins abgenommen werden können und somit eine besonders gute Handhabbarkeit gegeben ist. Vorzugsweise sind das Aufnahmeteil und das Antriebsteil über eine Steckverbindung verbunden, die durch Axialbewegung in Richtung der Magazindrehachse und/oder der Längsachse der aufgenommenen Bohrrohre lösbar ist. Insbesondere kann eine Steckverbindung am zentralen Achsrohr vorgesehen sein. Um eine Kraftübertragung zwischen Antriebsteil und aufgestecktem Aufnahmeteil zu erreichen, ist die Steckverbindung geeigneter Weise drehfest, insbesondere als Formschlussverbindung, ausgebildet.Furthermore, it is advantageous according to the invention that the rod magazine is in several parts with a receiving part on which the receptacles are arranged, and a drive part, on which a magazine rotary drive is provided, is formed, wherein the receiving part is in particular releasably secured to the drive part. In this way, a divisible magazine can be created, in which the recordings including the tubes mounted therein can be removed from the drive part of the magazine and thus a particularly good handling is given. Preferably, the receiving part and the drive part are connected via a plug connection, which is releasable by axial movement in the direction of the magazine rotation axis and / or the longitudinal axis of the recorded drill pipes. In particular, a plug connection can be provided on the central axle tube. In order to achieve a power transmission between the drive part and attached receiving part, the connector is suitably rotatable, in particular as a positive connection formed.
Für einen besonders sicheren Transport des entnommenen Gestängemagazins ist es vorteilhaft, dass ein Sicherungsdeckel vorgesehen ist, der geeigneter Weise stirnseitig auf das Gestängemagazin, insbesondere das Aufnahmeteil, aufsetzbar und arretierbar ist. Hierdurch kann das Gestängemagazin inklusive der magazinierten Innenrohre und der Außenrohre besonders sicher gehandhabt werden. Der Sicherungsdeckel wird bevorzugt an der den Aufnahmen abgewandten Stirnseite des Trommelmagazins vorgesehen.For a particularly safe transport of the removed rod magazine, it is advantageous that a safety cover is provided, which is suitably frontally on the rod magazine, in particular the receiving part, placed and locked. As a result, the rod magazine including the magazine inner tubes and the outer tubes can be handled very safe. The securing cover is preferably provided on the side facing away from the receptacles end face of the drum magazine.
Nach der Erfindung ist eine Lafette vorgesehen, die zum Führen eines Bohrantriebes des Doppelgestänges dient. Der Bohrantrieb kann ein einzelner Antrieb zum gleichzeitigen Antreiben beider Gestänge sein oder aus zwei separaten Antrieben bestehen, wobei der oder die Antriebe sowohl drehend als auch drehschlagend ausgebildet sein können. Die Handhabung der erfindungsgemäßen Vorrichtung wird dadurch erleichtert, dass die Drehachse des Revolvermagazins und/oder die Längsachsen der Aufnahmen zumindest annähernd parallel zur Lafette und/oder zu einer hieran verlaufenden Bohrachse angeordnet sind. Die Übergabeposition am Revolvermagazin befindet sich vorzugsweise auf gleicher Höhe wie die Bohrachse. In diesem Fall ist bei der Entnahme der Rohre aus dem Magazin nur eine Translationsbewegung erforderlich. Eine besonders kompakte Vorrichtung wird dadurch erhalten, dass das Gestängemagazin an der Lafette gelagert ist. Eine besonders einfache Bauform ist dadurch gegeben, dass zumindest ein Haltearm vorgesehen ist, an der das Gestängemagazin, insbesondere am zentralen Achsrohr, an der Lafette gelagert ist.According to the invention, a carriage is provided, which serves to guide a drill drive of the double rod. The drill drive may be a single drive for simultaneously driving both linkages or consist of two separate drives, wherein the one or more drives can be designed both rotationally and rotationally. The handling of the device according to the invention is facilitated by the fact that the axis of rotation of the revolving magazine and / or the longitudinal axes of the receptacles are arranged at least approximately parallel to the carriage and / or to a drilling axis extending thereon. The transfer position on the revolver magazine is preferably at the same height as the drilling axis. In this case, only one translational movement is required when removing the tubes from the magazine. A particularly compact device is obtained in that the rod magazine is mounted on the carriage. A particularly simple design is given by the fact that at least one holding arm is provided, on which the linkage magazine, in particular on the central axle tube, is mounted on the carriage.
Die Aufnahmen sind geeigneter Weise als Einschubhalterungen ausgebildet, welche die Rohre bei axialer Verschiebung freigeben. Beispielsweise kann das Halteelement für das Innenrohr einen Haltedorn aufweisen, auf den das Innenrohr aufgesteckt wird. Das Halteelement für das Außenrohr kann beispielsweise eine Aufnahmebuchse und/oder ebenfalls einen Aufnahmedorn aufweisen. Geeigneter Weise sind die beiden Halteelemente einer Doppelaufnahme für eine koaxiale Halterung des Außenrohres und des Innenrohres vorgesehen. Insbesondere wenn die Aufnahmen Buchsen zur Halterung der Rohre aufweisen, können diese auch als Köcher bezeichnet werden.The recordings are suitably designed as slide-in holders, which release the tubes during axial displacement. For example, the holding element for the inner tube may have a retaining pin, on which the inner tube is plugged. The holding element for the outer tube may, for example, have a receiving bush and / or likewise a receiving mandrel. Suitably, the two holding elements of a double receptacle for a coaxial mounting of the outer tube and the inner tube are provided. In particular, if the recordings have sockets for holding the tubes, they can also be referred to as quivers.
Vorzugsweise werden die Innenrohre so im Gestängemagazin gelagert, dass sie ein Stück aus dem umgebenden Außenrohr hervorstehen. Es ist dann bei einfacher Manipulatorausführung möglich, beide Rohre gemeinsam aus dem Magazin zu entnehmen. Sofern die Innenrohre gleich lang oder kürzer als die Außenrohre sind, kann hierfür vorgesehen sein, die Halteelemente für die Innenrohre mit einem Axialversatz gegenüber den Halteelementen für die Außenrohre auszubilden. Vorzugsweise weisen die Halteelemente einen ersten Anschlag für das Innenrohr und einen zweiten Anschlag für das Außenrohr auf, wobei die Anschläge axial gegeneinander versetzt sind. Vorzugsweise ist der Anschlag für das Innenrohr in Richtung auf das aufzunehmende Rohr und/oder ins Magazininnere hin versetzt.Preferably, the inner tubes are stored in the rod magazine so that they protrude a piece of the surrounding outer tube. It is then possible with simple manipulator design to remove both tubes together from the magazine. If the inner tubes are the same length or shorter than the outer tubes, this can be provided to form the holding elements for the inner tubes with an axial offset relative to the holding elements for the outer tubes. Preferably, the holding elements have a first stop for the inner tube and a second stop for the outer tube, wherein the stops are axially offset from each other. Preferably, the stop for the inner tube is offset in the direction of the male tube and / or inside the magazine.
Vorteilhafter Weise weist der Manipulator drei Bewegungsachsen auf, von denen eine etwa parallel zur Drehachse des Revolvermagazins, der Längsachse der Lafette und/oder den Längsachsen der Aufnahmen verläuft. Geeigneter Weise handelt es sich bei den Bewegungsachsen um bevorzugt orthogonale Linearachsen, wodurch besonders kompakte Abmessungen der erfindungsgemäßen Vorrichtung ermöglicht werden. Grundsätzlich kann es sich bei den Bewegungsachsen aber auch um Rotationsachsen handeln. Eine besonders robuste und vielseitige Anordnung ist dadurch gegeben, dass der Manipulator einen Manipulatorarm aufweist, der auf einer Längsführung verschiebbar ist. Die Längsführung ist geeigneter Weise an der Lafette vorgesehen oder Teil dieser Lafette. Der Manipulatorarm ist vorzugsweise teleskopierbar, insbesondere in insgesamt zwei Bewegungsrichtungen doppelt teleskopierbar ausgebildet.Advantageously, the manipulator has three axes of movement, one of which runs approximately parallel to the axis of rotation of the revolving magazine, the longitudinal axis of the carriage and / or the longitudinal axes of the receptacles. Suitably, the axes of motion are preferably orthogonal linear axes, thereby particularly compact dimensions of the device according to the invention are made possible. In principle, however, the axes of movement can also be rotational axes. A particularly robust and versatile arrangement is given by the fact that the manipulator has a manipulator arm which is displaceable on a longitudinal guide. The longitudinal guide is suitably provided on the carriage or part of this carriage. The manipulator arm is preferably telescopic, in particular in two directions of movement formed double telescopically.
Ein besonders schneller und sicherer Betrieb der erfindungsgemäßen Vorrichtung wird dadurch ermöglicht, dass der Manipulator zumindest zwei Greiferzangen aufweist. Die Greiferzangen sind erfindungsgemäß unabhängig voneinander betätigbar. Vorzugsweise sind die Greiferzangen mit einem Greifbereich ausgebildet, der sowohl den Durchmesser der Innenrohre als auch den Durchmesser der Außenrohre umfasst, so dass jede Greiferzange sowohl Außenrohre als auch Innenrohre greifen kann. Die beiden Greiferzangen sind bevorzugt in einer parallel zur Lafette und/oder zur Bohrachse verlaufenden Achse angeordnet. Geeigneter Weise sind die beiden Greiferzangen über ein Joch verbunden, das bevorzugt endseitig am Manipulator vorgesehen ist. Insbesondere kann vorgesehen werden, beim Entnehmen der Rohre aus dem Gestängemagazin das Innenrohr und das Außenrohr mit getrennten Greiferzangen zu fassen. Beim Einbringen der Rohre in das Gestängemagazin können beide Greiferzangen für dasselbe Rohr verwendet werden.A particularly fast and reliable operation of the device according to the invention is made possible in that the manipulator has at least two gripper tongs. The gripper tongs are actuated independently of each other according to the invention. Preferably, the gripper tongs are formed with a gripping area which comprises both the diameter of the inner tubes and the diameter of the outer tubes, so that each gripper tongs can grip both outer tubes and inner tubes. The two gripper tongs are preferably arranged in an axis running parallel to the carriage and / or to the drilling axis. Suitably, the two grippers are connected via a yoke, which is preferably provided on the end side on the manipulator. In particular, it can be provided to grasp the inner tube and the outer tube with separate gripping tongs when removing the tubes from the rod magazine. When inserting the tubes in the boom magazine both gripper tongs can be used for the same tube.
Vorzugsweise sind nach der Erfindung Mittel vorgesehen, mit denen das Gestängemagazin stufenlos positioniert und/oder arretiert werden kann. Dies erlaubt es, die Winkellagen der Aufnahmen, insbesondere die Entnahme- und/oder Beladeposition, stufenlos zu positionieren und zu arretieren.Preferably, according to the invention means are provided with which the rod magazine can be continuously positioned and / or locked. This allows the angular positions of the recordings, in particular the removal and / or loading position, to be infinitely positioned and locked.
Die Innenrohre können beispielsweise glatt oder als Schneckenbohrrohre ausgebildet sein. Sofern Schneckenbohrrohre verwendet werden, ist es vorteilhaft, wenn die Greiferzangen Klemmschalen aufweisen, die breiter als das Maß einer Wendelsteigung sind. Hierdurch kann ein sicherer Greifvorgang gewährleistet werden.The inner tubes may for example be smooth or formed as auger tubes. If auger tubes are used, it is advantageous if the gripper tongs have clamping shells that are wider than the extent of a helical pitch. As a result, a secure gripping operation can be ensured.
Die vorausgehend beschriebene Beschickungsvorrichtung ist erfindungsgemäß an einem Bohrgerät mit einer Bohreinrichtung vorgesehen, welche einen Bohrantrieb zum Doppelrohrbohren aufweist. Derartige Bohrgeräte können in bekannter Weise mit einem Fahrgestell, verschiedenen Aggregaten sowie einer Bedieneinheit ausgerüstet sein. Die Bohreinrichtung kann über einen Verstellmechanismus über dem Fahrgestell in nahezu jede beliebige Position gebracht werden.The charging device described above is inventively provided on a drill with a drilling device having a drill drive for double pipe drilling. Such drills can be equipped in a known manner with a chassis, various units and a control unit. The drilling device can be brought via an adjusting mechanism on the chassis in almost any position.
Erfindungsgemäß ist vorgesehen, dass der Bohrantrieb auf einer Lafette gelagert ist. Das erfindungsgemäße Bohrgerät ist unter anderem dadurch gekennzeichnet, dass das Gestängemagazin zwischen der Lafette und einem ersten Teleskoparm des Manipulators angeordnet ist und dass an den ersten Teleskoparm ein zweiter Teleskoparm mit den Greiferzangen verschiebbar gelagert ist. Der Manipulator und das Revolvermagazin können somit auf einer Seite der Lafette angeordnet werden, so dass auf der gegenüberliegenden Seite der Lafette für einen Bediener ein freier Zugang zum Bohrantrieb und dem Bohrstrang gegeben ist. Der Manipulator ist vorzugsweise unterhalb des Revolvermagazins an der Lafette befestigt. Der etwa C-förmig ausgebildete Manipulator umgreift' somit das Revolvermagazin, was zu einer besonders kompakten Anordnung führt.According to the invention it is provided that the drill drive is mounted on a carriage. The drill according to the invention is inter alia characterized in that the linkage magazine between the carriage and a first telescopic arm of the manipulator is arranged and that on the first telescopic arm, a second telescopic arm is slidably mounted with the gripper tongs. The manipulator and the revolver magazine can thus be arranged on one side of the carriage, so that on the opposite side of the carriage for an operator free access to the drill drive and the drill string is given. The manipulator is preferably mounted below the revolver magazine on the carriage. The approximately C-shaped manipulator 'thus surrounds the revolving magazine, resulting in a particularly compact arrangement.
Grundsätzlich kann das erfindungsgemäße Gestängemagazin statt mit einem Doppelgestänge auch mit einem Einfachgestänge bestückt werden. Die Auswechselbarkeit des Gestängemagazins kann als unabhängiger Erfindungsaspekt angesehen werden.Basically, the rod magazine according to the invention can be equipped with a single rod instead of a double rod become. The interchangeability of the linkage magazine can be regarded as an independent invention aspect.
Bei einem Verfahren kann vorgesehen sein, dass auf einer Doppelaufnahme ineinander angeordnete Rohre gemeinsam aus dem Gestängemagazin entnommen und in eine Bohrachse verbracht werden und/oder dass beim Magazinieren des Doppelgestänges zunächst die Innenrohre und anschließend die Außenrohre des Doppelgestänges im Gestängemagazin gelagert werden. Vorzugsweise wird zunächst das Innengestänge vollständig magaziniert und dann mit dem Magazinieren des Außengestänges begonnen.In one method, provision may be made for tubes, which are arranged one inside the other, to be taken out of the rod magazine together and placed in a drilling axis and / or that the inner tubes and then the outer tubes of the double rod are first stored in the rod magazine when the double rod is being magazineed. Preferably, first the inner rod is completely magazined and then started with the magazining of the outer rod.
