Abstract

An anchor drilling implement for producing soil anchors is described, which is provided with a drill carriage and a pivotable and vertically adjustable drilling mount. The drill carriage comprises a caterpillar gear and an implement upper part rotatable by means of a turntable and carrying a support for the mount. The implement upper part also carries a driving cab in the immediate vicinity of the support, so that said cab performs all the support movements and an unrestricted view of the drill hole or shaft is ensured in any position of the mount. The drilling mount is preferably also provided with a tool magazine, which can be controlled from the driving cab.

Description

Die Erfindung betrifft ein Ankerbohrgerät gemäß der DE-A-2435535 mit einem Bohrwagen und einer darauf angebrachten Lafette zum Einbringen von Lastankern in das Erdreich, wie es im Oberbegriff des Hauptanspruchs beschrieben ist.The invention relates to an anchor drilling device according to DE-A-2435535 with a drilling carriage and a mount mounted thereon for introducing load anchors into the ground, as described in the preamble of the main claim.

Bekanntlich werden im Tiefbau Lastanker zur Absicherung von Stützwänden in einem vorgegebenen Winkelbereich ausgeführt. Anschließend wird der Anker eingeführt und dann durch Einpressen eines Füllmaterials in seinem Endbereich verankert. Um günstige Quadratmeter-Preise beim Verbau zu erreichen, werden in zunehmendem Maße lange Großlastanker verwendet. Während früher überwiegend Einstabanker mit Durchmessern von 26 mm und 32 mm verbaut wurden, für die man Bohrgestänge mit Durchmessern von 70 bis 76 mm benötigte, sind für die heute vielfach verwendeten Litzenanker Bohrausrüstungen mit Durchmessern von 133 mm und mehr durchaus üblich.As is known, load anchors are used in civil engineering to secure supporting walls in a predetermined angular range. The anchor is then inserted and then anchored in its end region by pressing in a filler material. In order to achieve favorable square meter prices for shoring, long large load anchors are increasingly used. While in the past mainly single-rod anchors with diameters of 26 mm and 32 mm were used, for which drill rods with diameters of 70 to 76 mm were required, drilling equipment with diameters of 133 mm and more is quite common for the strand anchors that are widely used today.

Aus wirtschaftlichen und bohrtechnischen Gründen ist es hierbei erforderlich, mit zwei Bohrausrüstungen gleichzeitig zu arbeiten, so daß das Innengestänge mit der wertvollen Bohrkrone aus den bei den bekannten Bohrverfahren entstehenden verrohrten Bohrungen ausgebaut werden kann.For economic and drilling reasons, it is necessary to work with two drilling equipments at the same time, so that the inner rod with the valuable drill bit can be removed from the cased bores produced in the known drilling methods.

Die Bedienung eines Ankerbohrgerätes und insbesondere das Auswechseln des Bohrgestänges kann in der rauhen Umgebung einer Baustelle mit großen körperlichen Anstrengungen verbunden sein.The operation of an anchor drilling machine and in particular the replacement of the drill pipe can be associated with great physical exertion in the harsh environment of a construction site.

Der Erfindung liegt die Aufgabe zugrunde, ein Ankerbohrgerät der eingangs genannten Art anzugeben, bei welchem die Bedienung vereinfacht und die Umrüstzeiten verkürzt werden und gleichzeitig die Verwendung von schwerem Ankerbohrwerkzeug ermöglicht wird.The invention has for its object to provide an anchor drilling machine of the type mentioned, in which the operation is simplified and the changeover times are shortened and at the same time the use of heavy anchor drilling tool is made possible.

Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Hauptanspruchs gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved in accordance with the characterizing part of the main claim. Developments of the invention are described in the subclaims.

Die Erfindung hat den Vorteil, daß große Kräfte von der Bohrlafette über den Support auf das drehbare Geräteoberteil übertragen werden können und die Bedienung und Überwachung des Ankerbohrgeräts während des Bohrbetriebs einschließlich der Bohr-, Verpreß- und Zieharbeit allein vom Bohrmeister durchgeführt werden kann. Der Bedienungsplatz kann äußerst nahe am Bohrpunkt angeordnet werden, so daß er eine optimale Sicht auf den Bohrpunkt und den Bohrstrang hat. Durch die Anordnung der Lafette fällt Bohrgut frei zu Boden und berührt keine Maschinenteile. Durch den automatisierten Gestängeauf- und -abbau sowie das Ein- und Ausmagazinieren ist Handarbeit nicht mehr erforderlich und es kann Gestänge mit relativ großem Durchmesser, beispielsweise bis zu einem Durchmesser von 176 mm, und in großen Längen, bis beispielsweise 6 m, verarbeitet werden. Auf diese Weise werden einerseits ein großer Bohrfortschritt und kurze Stillstandszeiten erreicht und andererseits kann schwere körperliche Arbeit vermieden werden.The invention has the advantage that large forces can be transmitted from the drilling mount via the support to the rotatable upper part of the device and the operation and monitoring of the anchor drilling device during drilling operation including drilling, pressing and pulling work can be carried out by the drilling master alone. The operator station can be arranged very close to the drilling point so that it has an optimal view of the drilling point and the drill string. Due to the arrangement of the carriage, drilling material falls freely to the ground and does not touch any machine parts. Due to the automated boom assembly and dismantling as well as the loading and unloading, manual labor is no longer necessary and booms with a relatively large diameter, for example up to a diameter of 176 mm, and in long lengths, for example up to 6 m, can be processed. In this way, great drilling progress and short downtimes are achieved on the one hand, and heavy physical work can be avoided on the other.

Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels weiter beschrieben.

  • Fig. 2 zeigt schematisch einen Querschnitt entlang der Schnittlinie A-B durch die Lafette des Ankerbohrgeräts gemäß Fig. 1 und
  • Fig. 3 zeigt schematisch eine Draufsicht auf das Ankerbohrgerät gemäß Fig. 1.
The invention is described below with reference to an embodiment shown in the drawing.
  • Fig. 1 shows schematically a front view of an anchor drilling machine;
  • FIG. 2 schematically shows a cross section along the section line AB through the mount of the anchor drilling machine according to FIGS. 1 and
  • FIG. 3 schematically shows a top view of the anchor drilling machine according to FIG. 1.

Wie Fig. 1 zeigt, weist ein insgesamt mit 10 bezeichnetes Ankerbohrgerät einen Bohrwagen 11 mit einem Raupenfahrwerk 12 auf. Auf dem Raupenfahrwerk 12 ist über einen Drehkranz 13 ein Geräteoberteil 14 drehbar gelagert. Es umfaßt ein Antriebsaggregat 15, einen von einem geschlossenen Führerhaus 16 umgebenen Bedienungsplatz für einen Bohrmeister sowie einen im wesentlichen senkrecht zum Drehkranz 13 angeordneten Support 17 zur Aufnahme einer Bohrlafette 18.As shown in FIG. 1, an anchor drilling device, designated overall by 10, has a drilling carriage 11 with a crawler track 12. On the crawler track 12, a device upper part 14 is rotatably mounted via a slewing ring 13. It comprises a drive unit 15, an operator station for a drilling master surrounded by a closed driver's cab 16 and a support 17 arranged essentially perpendicular to the slewing ring 13 for receiving a drill carriage 18.

Die Bohrlafette 18 ist in einem Schlitten 19 schwenkbar gelagert, der höhenverschiebbar auf dem Support 17 geführt ist.The drill carriage 18 is pivotally mounted in a carriage 19, which is guided on the support 17 so as to be displaceable in height.

Die Bohrlafette 18 trägt einen Bohrantrieb 20 sowie eine vordere Halterung 21 und Klemmbacken 32 für einen Bohrer (nicht dargestellt) oder ein Bohrgestänge, mit welchem der Bohrer bzw. das Bohrgestänge in der Bohrposition gehalten wird. Um die Darstellung übersichtlich zu halten, ist eine rückwärtige Halterung für den Bohrer bzw. das Bohrgestänge in der Bohrposition nicht wiedergegeben. In Fig. 1 ragt ein Bohrgestänge-Abschnitt 22 in Bohrrichtung über die Halterung 21 bzw. die Bohrlafette 18 hinaus, wo er gemäß Pfeil 23 beim Abteufen der Bohrung nach außen und beim Ziehen nach innen bewegt wird. Im übrigen ist das Bohrgestänge in Bohrposition drehbar an der Bohrlafette 18 gehalten.The drill carriage 18 carries a drill drive 20 as well as a front holder 21 and clamping jaws 32 for a drill (not shown) or a drill pipe with which the drill or drill pipe is held in the drilling position. In order to keep the presentation clear, a rear holder for the drill or the drill pipe in the drilling position is not shown. In Fig. 1, a drill pipe section 22 protrudes in the drilling direction beyond the holder 21 or the drilling mount 18, where it is moved according to arrow 23 when drilling the hole outwards and when pulling inwards. Otherwise, the drill string is rotatably held in the drilling position on the drilling mount 18.

Der Support 17 befindet sich in Fahrtrichtung an der vorderen Begrenzung des Bohrwagens 11, so daß die Bohrlafette 18 in der Zeichenebene im Freiraum vor dem Support 17 und dem Raupenfahrwerk 12 geschwenkt werden kann. Auf diese Weise kann die Bohrlafette 18 in einen beliebigen Neigungswinkel verschwenkt werden. Die Ansatzhöhe für den Bohrpunkt wird durch eine Längsverschiebung des Schlittens 19 festgelegt. Der Support besteht aus zwei querversteiften Stahlschienen 43.The support 17 is located in the direction of travel on the front boundary of the drilling carriage 11, so that the drilling mount 18 can be pivoted in the plane of the drawing in front of the support 17 and the crawler track 12. In this way, the drill carriage 18 can be pivoted to any angle. The starting height for the drilling point is determined by a longitudinal displacement of the slide 19. The support consists of two cross-stiffened steel rails 43.

Das Verschwenken der Bohrlafette 18 erfolgt hydraulisch mittels eines Hydraulikzylinders 24 der zwischen dem rückwärtigen Ende der Bohrlafette 18 und einem Arm 25 an der Oberseite des Schlittens 19 angeordnet ist. Auch der Schlitten 19 ist hydraulisch höhenverstellbar.The pivoting of the drill carriage 18 takes place hydraulically by means of a hydraulic cylinder 24 which is arranged between the rear end of the drill carriage 18 and an arm 25 on the upper side of the carriage 19. The carriage 19 is also hydraulically adjustable in height.

Die Bohrlafette 18 trägt ferner ein hydraulisch betätigtes Gestängemagazin 26 zur Aufnahme von mehreren Gestängerohren 27, die in dem hier dargestellten Beispiel in einer Reihe senkrecht zur Zeichenebene liegen, so daß lediglich das erste Gestängerohr sichtbar ist und die übrigen Gestängerohre verdeckt werden. Von den Gestängerohren 27 im Gestängemagazin 26 wird ferner auch das Bohrgestänge verdeckt, welches sich in Verlängerung des Bohrgestängeabschnitts 22 in der Bohrposition befindet.The drill carriage 18 also carries a hydraulically operated rod magazine 26 for receiving a plurality of rod tubes 27, which in the example shown here lie in a row perpendicular to the plane of the drawing, so that only the first rod tube is visible and the other rod tubes are covered. The drill pipe, which is located in the extension of the drill pipe section 22 in the drilling position, is also covered by the drill pipe 27 in the drill magazine 26.

Das Gestängemagazin 26 umfaßt zwei etwa U-förmige Halterungen 28,29 die senkrecht zur Zeichenebene in der Weise an der Bohrlafette 18 befestigt sind, daß das Gestängemagazin 26 jede Schwenk- und Vertikalbewegung der Bohrlafette 18 mitmacht. Somit ist der Wiederholvorgang des Ein- und Ausmagazinierens in jeder Stellung der Bohrlafette 18 gewährleistet.The rod magazine 26 comprises two approximately U-shaped brackets 28, 29 which are fastened to the drill carriage 18 perpendicular to the plane of the drawing in such a way that the rod magazine 26 follows every pivoting and vertical movement of the drill carriage 18. The repetition of the loading and unloading in any position of the drill carriage 18 is thus ensured.

Fig. 2 zeigt einen Querschnitt A-B durch die Bohrlafette 18 und das Gestängemagazin 26. Demnach besteht die Bohrlafette 18 aus einem Stahlträger 36 an dessen Unterseite eine hintere Halterung 30 für ein Gestängerohr 31 in der Bohrposition angeordnet ist. Das Gestängerohr 31 ist in der hinteren Halterung 33 drehbar gelagert, wobei es von zwei Backen 32 gehalten ist. Die nachfolgend beschriebenen Einzelheiten des Gestängemagazins 26 beziehen sich auf die Halterung 29, die im übrigen mit der Halterung 28 (Fig. 1) gleichartig ist. Auf der Oberseite der Bohrlafette 18 ist ein quer zu deren Längsachse verlaufender weiterer Hydraulikzylinder 33 angeordnet, über welchen eine Schubstange 34 gemäß Pfeil 35 längsverschiebbar ist. Am freien Ende der Schubstange 34 befindet sich ein Trägerarm 37, an dessen freiem Ende eine Gabel 38 zur Aufnahme der Gestängerohre 27 befestigt ist. Die Gabel 38 dient als Längsmagazin für die Gestängerohre 27, die zwischen einem oberen und einem unteren Gabelarm 39,40 parallel zur Schubstange 34 nebeneinanderliegend lösbar eingespannt sind. Das Einspannen erfolgt mit Hilfe von Hydraulikzylindern 41 die jeweils einem der Gestängerohre zugeordnet sind. Hierbei sind die Hydraulikzylinder 41 am unteren Gabelarm 40 abgestützt, während die Gestängerohre 27 mit Hilfe von Haltebacken 42 an den freien Enden der Hydraulikzylinder 41 an den oberen Gabelarm 39 angedrückt werden. Durch einen entsprechenden Druck können die Gestängerohre 27 in jeder Lage der Bohrlafette 18 sicher gehalten werden.2 shows a cross section AB through the drill carriage 18 and the rod magazine 26. Accordingly, the drill carriage 18 consists of a steel support 36, on the underside of which a rear holder 30 for a drill pipe 31 is arranged in the drilling position. The drill pipe 31 is rotatably mounted in the rear holder 33, being held by two jaws 32. The details of the rod magazine 26 described below relate to the holder 29, which is otherwise identical to the holder 28 (FIG. 1). On the top of the drill carriage 18 is a further hydraulic cylinder running transversely to its longitudinal axis 33 arranged over which a push rod 34 is longitudinally displaceable according to arrow 35. At the free end of the push rod 34 there is a support arm 37, at the free end of which a fork 38 for receiving the drill pipe 27 is attached. The fork 38 serves as a longitudinal magazine for the drill pipes 27, which are releasably clamped side by side between an upper and a lower fork arm 39, 40 parallel to the push rod 34. The clamping takes place with the aid of hydraulic cylinders 41, which are each assigned to one of the drill pipes. Here, the hydraulic cylinders 41 are supported on the lower fork arm 40, while the drill pipes 27 are pressed onto the upper fork arm 39 by means of holding jaws 42 on the free ends of the hydraulic cylinders 41. The drill pipes 27 can be held securely in any position of the drilling mount 18 by a corresponding pressure.

Bei einem Gestängewechsel wird die Gabel 38 durch eine Längsbewegung der Schubstange 34 in eine Position unterhalb der Bohrlafette 18 in der Weise verschoben, daß ein in der Gabel 38 liegendes Gestängerohr 27 in einer Position zu liegen kommt, in welcher es mit einem bereits abgebohrten Gestängeabschnitt 22 (Fig. 1) verschraubt werden kann bzw. von einem derartigen Rohrabschnitt 22 abgeschraubt werden kann. Durch ein Öffnen des betreffenden Hydraulikzylinders 41 ist eine Entnahme aus der Gabel 38 bzw. eine Aufnahme in die Gabel 38 ohne weiteres möglich. Auch das Verschrauben kann mit Hilfe der hydraulisch betätigbaren Klemmbacken 32 selbsttätig unter Steuerung vom Führerhaus 16 aus erfolgen.When changing the boom, the fork 38 is moved by a longitudinal movement of the push rod 34 into a position below the drill carriage 18 in such a way that a drill pipe 27 lying in the fork 38 comes to lie in a position in which it is already drilled with a boom section 22 (Fig. 1) can be screwed or unscrewed from such a pipe section 22. By opening the relevant hydraulic cylinder 41, removal from the fork 38 or inclusion in the fork 38 is readily possible. The screwing can also be carried out automatically with the aid of the hydraulically actuated clamping jaws 32 under control from the driver's cab 16.

Um die Figur übersichtlich zu halten, sind alle Leitungsverbindungen vom Antriebsaggregat 15 zu den einzelnen Hydraulikzylindern nicht in der Figur wiedergegeben.In order to keep the figure clear, all line connections from the drive unit 15 to the individual hydraulic cylinders are not shown in the figure.

Aus der Draufsicht auf das Ankerbohrgerät 10 gemäß Fig. 3 wird ersichtlich, daß das Führerhaus 16 in unmittelbarer Nähe des dem Bohrloch zugewandten Bereichs der Bohrlafette 18 und am in Fahrtrichtung vorne liegenden Ende des Bohrwagens 11 angeordnet ist. Die Bedienungsperson hat somit alle für den Bohrvorgang wesentlichen Aggregate und das Bohrloch ungestört im Blickfeld. Da ferner alle Steuereinrichtungen unter ergonomischen Gesichtspunkten im Führerhaus 16 angeordnet sind, kann das Ankerbohrgerät 10 zuverlässig von einer einzigen Bedienungsperson gesteuert werden.From the top view of the anchor drilling machine 10 according to FIG. 3 it can be seen that the driver's cab 16 is arranged in the immediate vicinity of the region of the drilling mount 18 facing the borehole and at the end of the drilling carriage 11 lying in the direction of travel. The operator thus has all the units essential for the drilling process and the borehole undisturbed in view. Furthermore, since all control devices are arranged in the cab 16 from an ergonomic point of view, the anchor drilling machine 10 can be reliably controlled by a single operator.

Der Support 17 und die Bohrlafette 18 liegen mit einem genügend großen Freiraum in Fahrtrichtung vor dem Ende des Raupenfahrwerks 12, so daß eine ungehinderte Schwenkbewegung der Bohrlafette 18 möglich ist. Außerdem wird durch diese weit vorstehende Anordnung erreicht, daß auch bei einer Drehbewegung des Geräteoberteils auf dem Raupenfahrwerk gemäß Pfeil 44 in jeder Drehstellung genügend Freiraum für eine ungehinderte Schwenkbewegung der Bohrlafette 18 vorhanden ist.The support 17 and the drill carriage 18 lie with a sufficiently large free space in the direction of travel before the end of the crawler track 12, so that an unimpeded pivoting movement of the drill carriage 18 is possible. In addition, this far-above arrangement ensures that even with a rotational movement of the upper part of the caterpillar under arrow 44 there is sufficient space in each rotational position for an unimpeded pivoting movement of the drilling mount 18.

Da der Support 17 unmittelbar am Geräteoberteil 14 befestigt ist, kann er sehr hohe Kräfte aufnehmen. Somit kann die Bohrlafette 18 bis zu 10 m lang sein und mit mehreren entsprechend langen Gestängerohren belastet werden. Außerdem kann der Support 17 große Vortriebskräfte aufnehmen. Insbesondere wenn der Support 17 am Geräteoberteil 14 nicht angelenkt sondern mit einer festen Schraub- oder Schweißverbindung befestigt ist, können große Kräfte aufgenommen werden, ohne daß wesentliche Einschränkungen bezüglich des Freiheitsgrades bei der Ausrichtung der Bohrlafette 18 in Kauf genommen werden müssen.Since the support 17 is attached directly to the device upper part 14, it can absorb very high forces. The drill carriage 18 can thus be up to 10 m long and can be loaded with several correspondingly long drill rods. In addition, the support can accommodate 17 large propulsive forces. In particular, if the support 17 is not articulated on the device upper part 14 but is fastened with a fixed screw or welded connection, large forces can be absorbed without having to accept significant restrictions with regard to the degree of freedom in the alignment of the drilling mount 18.

In jeder Drehstellung des Geräteoberteils befindet sich ferner das Führerhaus 16 in der optimalen Entfernung zum Bohrloch.In every rotational position of the upper part of the device, the driver's cab 16 is also at the optimal distance from the borehole.

Es kann zweckmäßig sein, den Support 17 mit einer leichten Neigung nach hinten auf die Mitte des Ankerbohrgeräts 10 zu versehen. Durch diese Maßnahme wird sichergestellt, daß die Ankerlafette 18 mit zunehmender Höhenverstellung zur Gewichtsverlagerung näher an den Mittelpunkt des Ankerbohrgeräts 10 versetzt wird. Somit wird eine zuverlässige Standfestigkeit des Ankerbohrgeräts 10 erreicht.It can be expedient to provide the support 17 with a slight inclination towards the center of the anchor drilling machine 10. This measure ensures that the anchor mount 18 is moved closer to the center of the anchor drilling device 10 with increasing height adjustment for weight shifting. Reliable stability of the anchor drilling machine 10 is thus achieved.
