Description
Die Erfindung betrifft eine Bohrgeräteanordnung mit einem Bohrgerät, welches ein Raupenfahrwerk aufweist, an welchem eine Bohrlafette mit einem Bohrantrieb gelagert ist, welche zum Antreiben eines Bohrgestänges ausgebildet und entlang der Bohrlafette axial verfahrbar gelagert ist, wobei die Bohrlafette über einen Mehrgelenkarm in einer Vielzahl von Bohrpositionen im Raum verstellbar ist, und mit einer Bedienkabine für mindestens eine Bedienperson zum Steuern des Bohrgeräts, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a drill rig with a drill, which has a crawler track on which a drill mount is mounted with a drill drive, which is designed for driving a drill string and axially movable along the drill mount, the drill mount via a Mehrgelenkarm in a variety of drilling positions in the room is adjustable, and with a control cabin for at least one operator for controlling the drill, according to the preamble of claim 1.
Die Erfindung betrifft weiterhin ein Verfahren zum Erstellen einer Bohrung, insbesondere einer Injektionszugankerbohrung, insbesondere mit einer solchen Bohrgeräteanordnung, bei dem ein Bohrgestänge mit einem Bohrkopf von einem Bohrantrieb drehend angetrieben wird, welcher zum Einbringen der Bohrung in einen Boden- oder Wandbereich entlang einer Bohrlafette axial verfahren wird, welche mittels eines Mehrgelenkarms eines Bohrgeräts in eine Vielzahl von Bohrpositionen im Raum verstellbar ist, wobei ein Bohrbetrieb von mindestens einer Bedienperson aus einer Bedienkabine heraus gesteuert wird, gemäß dem Oberbegriff des Anspruchs 10.The invention further relates to a method for creating a bore, in particular an injection tie rod bore, in particular with such a drill assembly, in which a drill string is driven in rotation with a drill head by a drill drive, which for introducing the bore in a bottom or wall region along a Bohrlafette axially method, which is adjustable by means of a Mehrgelenkarms a drill in a variety of drilling positions in space, wherein a drilling operation is controlled by at least one operator out of an operating cab, according to the preamble of claim 10th
Derartige Bohrgeräte werden auch als Ankerbohrgeräte bezeichnet. Da Anker nicht nur vertikal in den Boden sondern in vielen Fällen in einer Vielzahl unterschiedlicher Winkel in Wand- und Deckenbereiche, etwa zum Stützen von Baugrubenwänden oder zur Hang- oder Tunnelsanierung eingebracht werden, ist eine Bohrlafette über einen Mehrgelenkarm gegenüber einem Grundgerät in einer Vielzahl von Bohrpositionen frei im Raum verstellbar. Ein solches Bohrgerät geht beispielsweise aus der
Ein Oberwagen an einem solchen Bohrgerät ist dabei sehr kompakt ausgebildet, um die Vielzahl von Verstellmöglichkeiten der Bohrlafette im Raum möglichst nicht zu behindern und einzuschränken. Üblicherweise befindet sich die Bedienkabine in einem hinteren Bereich des Bohrgerätes, wobei die Bedienkabine häufig als ein einfacher Bedienstand ausgebildet ist.A superstructure on such a drill is designed to be very compact in order not to hinder and limit the variety of adjustment of the drill mount in the room as possible. Usually, the control cabin is located in a rear region of the drill, wherein the control cabin is often designed as a simple control station.
Häufig verdeckt die Bohrlafette auch die Sicht vom Bedienstand auf den Arbeitsbereich in der Nähe des Bohransatzpunktes. Für ein positionsgenaues Einbringen von Bohrungen mittels der im Raum frei verstellbaren Bohrlafette ist es daher oftmals erforderlich, dass sich die Bedienperson aus dem Bedienstand entfernt und sich nahe an dem Arbeitsbereich positioniert, so dass die Bedienperson eine gute Sicht auf den Arbeitsbereich mit dem Bohransatzpunkt besitzt. Die Steuerung des Bohrgerätes erfolgt in diesen Fällen über ein tragbares Bedienpult, welches die Bedienperson mit sich trägt. Das Bedienpult ist relativ schwer und trotz Verwendung von Tragriemen auf Dauer belastend.Often, the drill mount also obscures the view from the operator's console to the work area near the drill bit's point. For a positionally accurate drilling by means of freely adjustable in the space drill mount, it is therefore often necessary that the operator away from the control stand and positioned close to the work area, so that the operator has a good view of the work area with the Bohransatzpunkt. The control of the drill in these cases via a portable control panel, which carries the operator with him. The control panel is relatively heavy and burdensome in the long term despite the use of shoulder straps.
Zudem hat diese Anordnung den Nachteil, dass die Bedienperson sich ungeschützt im Freien befindet. Die Bedienperson ist somit Witterungseinflüssen an der Baustelle ausgesetzt. Bei schlechter Witterung kann dies den Bohrbetrieb beeinträchtigen oder sogar zum Erliegen bringen. Darüber hinaus ist die Positionierung des ungeschützten Bedieners unmittelbar am Bohrpunkt auch unter dem Gesichtspunkt der Arbeitssicherheit nachteilig.In addition, this arrangement has the disadvantage that the operator is unprotected outdoors. The operator is thus exposed to weather conditions at the site. In bad weather this can affect the drilling operation or even bring to a standstill. In addition, the positioning of the unprotected operator immediately at the drilling point is disadvantageous from the point of view of occupational safety.
Der Erfindung liegt die Aufgabe zugrunde, eine Bohrgeräteanordnung und ein Verfahren zum Erstellen einer Bohrung anzugeben, mit welchen einerseits weiterhin ein hoher Freiheitsgrad bei der Positionierung der Bohrlafette im Raum gegeben ist und andererseits eine gute Bedienbarkeit und ein Schutz für die Bedienperson gegeben sind.The invention has for its object to provide a drill assembly and a method for creating a hole, with which on the one hand continues to give a high degree of freedom in the positioning of the drill mount in space and on the other hand, a good operability and protection for the operator are given.
Die Aufgabe wird zum einen durch eine Bohrgeräteanordnung mit den Merkmalen des Anspruchs 1 und zum anderen durch ein Verfahren zum Erstellen einer Bohrung mit den Merkmalen des Anspruchs 10 gelöst.The object is achieved, on the one hand, by a drill device arrangement having the features of claim 1 and, on the other hand, by a method for producing a bore having the features of claim 10.

Eine Grundidee der Erfindung kann darin gesehen werden, das Bohrgerät zweiteilig auszubilden und die Bedienkabine als eine mobile Bedieneinheit auszugestalten. Die mobile Bedieneinheit wird dabei nach der Erfindung mit einem eigenständigen Fahrwerk versehen, so dass sich die Bedienperson mit der mobilen Bedieneinheit bewegen kann. Durch die getrennte und mobile Ausgestaltung der Bedieneinheit mit einem eigenständigen Fahrwerk kann diese unabhängig vom Bohrgerät verfahren werden. Damit kann die Bedieneinheit stets so angeordnet werden, dass diese in der konkreten Baustellensituation die Verstellbarkeit der Bohrlafette im Raum nicht behindert. Gleichzeitig kann die Bedieneinheit über das eigenständige Fahrwerk von der Bedienperson so verfahren werden, dass stets eine gute Sicht auf den Bohransatzpunkt erreicht werden kann.A basic idea of the invention can be seen to form the drill in two parts and to design the control cabin as a mobile control unit. The mobile control unit is provided according to the invention with an independent chassis, so that the operator can move with the mobile control unit. Due to the separate and mobile design of the control unit with an independent chassis this can be moved independently of the drill. Thus, the control unit can always be arranged so that it does not hinder the adjustability of the drill mount in space in the specific construction site situation. At the same time, the operating unit can be moved over the independent chassis of the operator so that always a good view of the Bohransatzpunkt can be achieved.
Grundsätzlich kann die Bedienkabine in einer beliebigen, insbesondere leitungsgebundenen Weise mit dem Bohrgerät in Verbindung stehen. Besonders bevorzugt ist es nach einer Ausführungsform der Erfindung, dass die Bedienkabine ein Bedienpult aufweist, welches drahtlos mit einer Steuereinrichtung des Bohrgeräts in Verbindung steht. Somit wird eine hohe Unabhängigkeit und Bewegungsfreiheit zwischen dem Bohrgerät einerseits und der Bedienkabine andererseits erreicht. Für bestimmte Zwecke kann an dem Bohrgerät weiter ein fester Bedienstand, vorzugsweise in einer vereinfachten Ausführung, vorgesehen sein. Die leitungslose Verbindung ist insbesondere eine Funksignalverbindung.In principle, the operating cabin can be connected to the drilling device in any manner, in particular in a line-connected manner. According to one embodiment of the invention, it is particularly preferred for the operator's cab to have a control console which is wirelessly connected to a control device of the drill. Thus, a high degree of independence and freedom of movement between the drill on the one hand and the control cabin on the other hand is achieved. For certain purposes, a fixed operating stand, preferably in a simplified embodiment, may be provided on the drilling apparatus. The wireless connection is in particular a radio signal connection.
Grundsätzlich kann die mobile Bedieneinheit nur für eine einzelne Person vorgesehen sein. Bevorzugt ist es nach einer Ausführungsform der Erfindung, dass die Bedienkabine zum Aufnehmen von mindestens zwei Personen ausgebildet ist. Die beiden Personen können dabei unterschiedliche Funktionen übernehmen. So kann ein Fahrer zum Verfahren der mobilen Bedieneinheit sowie die eigentliche Bedienperson für das Bohrgerät geschützt angeordnet werden. Grundsätzlich kann die mobile Bedieneinheit auch zum Steuern mehrerer Bohrgeräte vorgesehen sein, so dass ein effektiver Personaleinsatz ermöglicht ist.In principle, the mobile operating unit can be provided only for a single person.

Hierdurch wird ein besonders guter Arbeitsschutz sowie ein Schutz vor Witterungseinflüssen erreicht.In principle, the control cabin of the mobile control unit can be designed as an open control station. It is particularly advantageous according to a development of the invention that the control cab is designed to be closed. The control cabin can be provided in particular with windows and doors and preferably with protective grilles and air conditioning. As a result, a particularly good occupational safety and protection from the weather is achieved.
Eine besonders gute Mobilität wird dadurch erreicht, dass das Fahrwerk der mobilen Bedieneinheit als ein Raupenfahrwerk oder ein Radfahrwerk ausgebildet ist. Das Fahrwerk kann etwa ähnlich dem Fahrwerk von sogenannten Minibaggern, welche ebenfalls als Raupen- oder Radfahrzeuge angeboten werden, ausgebildet sein. Diese sind kostengünstig zu beziehen und bieten eine hohe Wendigkeit auch in einem unwegsamen Gelände. Grundsätzlich kann die mobile Bedieneinheit so kompakt ausgebildet sein, dass diese mit dem eigentlichen Bohrgerät lösbar gekoppelt werden kann. Das Bohrgerät kann so mit der mobilen Bedieneinheit auch als eine Einheit verfahren werden.A particularly good mobility is achieved in that the chassis of the mobile control unit is designed as a crawler undercarriage or a wheel gear. The chassis can be similar to the chassis of so-called mini excavators, which are also offered as caterpillars or wheeled vehicles, trained. These are inexpensive to purchase and offer a high maneuverability even in rough terrain. In principle, the mobile operating unit can be made so compact that it can be releasably coupled to the actual drill. The drill can thus be moved with the mobile control unit as a unit.
Eine weitere Verbesserung der Bedienbarkeit des Bohrgerätes und der Einsetzbarkeit der mobilen Bedieneinheit wird nach einer Weiterbildung der Erfindung dadurch erzielt, dass das Fahrwerk als ein Unterwagen ausgebildet ist und dass auf dem Unterwagen ein Oberwagen mit der Bedienkabine drehbar gelagert ist. Insgesamt kann so eine sehr gute Übersicht der Bedienperson in der mobilen Bedieneinheit auch auf mehrere Bohrgeräte oder auf die Baustelle insgesamt erzielt werden.A further improvement of the operability of the drill and the usability of the mobile control unit is achieved according to a development of the invention in that the chassis is designed as an undercarriage and that on the undercarriage, a superstructure with the control cab is rotatably mounted. Overall, a very good overview of the operator in the mobile control unit can be achieved on several drills or on the construction site as a whole.
Nach der Erfindung besteht eine weitere Verbesserung der Bohrgeräteanordnung darin, dass die mobile Bedieneinheit mit einer Antriebsrichtung versehen ist, welche zum Antreiben mindestens einer Arbeitseinrichtung ausgebildet ist. Somit kann die mobile Bedieneinheit auch neben einer reinen Bedien- und Steuerungsfunktion auch als ein zusätzliches Arbeitsgerät für bestimmte Aufgaben herangezogen werden.According to the invention, a further improvement of the drill arrangement is that the mobile operating unit is provided with a drive direction which is designed to drive at least one working device. Thus, the mobile control unit can also be used as an additional working device for certain tasks in addition to a pure control and operation function.
Besonders vorteilhaft ist es nach einer Weiterbildung der Erfindung, dass die Arbeitseinrichtung ein Hebezeug, eine Greifeinrichtung, einen Tragarm und/oder eine Seilwinde aufweist. Insbesondere kann die mobile Bedieneinheit mit einer Greifeinrichtung an einem bewegbaren Tragarm versehen sein, so dass mit der mobilen Bedieneinheit auch Handhabungen von Bohrgestängeelementen durchgeführt werden können. So können neue Bohrgestängeelemente an die Bohrlafette zugeführt oder beim Demontieren des Bohrgestänges Bohrgestängeelemente abgeführt und zu einem Magazin transportiert werden.It is particularly advantageous according to a development of the invention that the working device comprises a hoist, a gripping device, a support arm and / or a winch. In particular, the mobile operating unit may be provided with a gripping device on a movable support arm, so that also manipulations of drill string elements are performed with the mobile operating unit can.
