Description

An einem Baggerausleger anbaubare Bohrlafette Drill mount attachable to an excavator boom
Die Erfindung bezieht sich auf eine Bohrlafette zum Anbringen vonThe invention relates to a drill carriage for attaching
Bohrlöchern in Gestein, bei welcher ein Bohran trieb, insbesondere ein Hydraulikhammer über eine Führung in Bohrrichtung geführt ist, wobei die Bohrlafette schwenkbar an einer fahrbaren Tragvorrichtung angebracht ist und wobei zwischen der Tragvorrichtung und der schwenkbaren Halterung der Bohrlafette ein Drehgelenk vorgesehen ist.Boreholes in rock, in which a Bohran drove, in particular a hydraulic hammer is guided over a guide in the direction of drilling, the drill carriage is pivotally attached to a mobile support device and wherein a swivel joint is provided between the support device and the pivotable holder of the drill carriage.
Eine derartige Vorrichtung ist z.B. der AT-PS 390 647 entnehmbar. Solche -Einrichtungen dienen üblicherweise zum Anbringen von Sprenglöchern und zwar derart, daß die Bohrlafette mittels der fahrbaren Tragvorrichtung, bei dieser bekannten Ausbildung ein Bohrwagen, in die gewünschte Lage gebracht wird, wonach dann die Bohrlöcher in der gewünschten Richtung in den Fels eingebracht werden, in welche Bohrlöcher später Sprengladungen eingesetzt und gezündet werden, um z.B. einen entsprechenden Tunnelvortrieb oder einen Bodenaushub zu bewerkstelligen. Bei dieser bekannten Ausbildung ist allerdings nur ein Horizontalbohren oder ein Schrägbohren ermöglicht, nicht jedoch ein Vertikalbohren.Such a device is e.g. the AT-PS 390 647 removable. Such devices are usually used to attach blast holes in such a way that the drill carriage is brought into the desired position by means of the mobile carrying device, in this known design a drill carriage, after which the drill holes are then introduced into the rock in the desired direction which boreholes will be used and detonated later, e.g. to carry out a corresponding tunneling or excavation. In this known design, however, only horizontal drilling or oblique drilling is possible, but not vertical drilling.
Eine ähnliche Anordnung geht auch aus der EP-AI 0 525 186 hervor. Für Vertikalbohrungen ist es bekannt, Bohrlafetten an das Ende eines Baggerauslegers anzubringen, und zwar geht dies im Prinzip aus der japanischen Auslegeschrift 3-151493 hervor. All den bekannten Ausbildungen ist gemeinsam, daß die Bohrlafette nur begrenzt verschwenk- beziehungsweise plazierbar ist, insbesondere ist es nicht möglich, nahe am Boden Horizontalbohrungen vorzunehmen. Dies ist aber bei Tunnelvorschub oder auch bei Künetten erforderlich. Der Erfindung liegt daher die Aufgabe zugrunde, eine Bohrlafette der eingangs genannten Art zu schaffen, mittels welcher Bohrlöcher an jeder beliebigen Stelle und in jeder beliebigen Richtung erzeugt werden können.A similar arrangement is also evident from EP-AI 0 525 186. For vertical drilling, it is known to attach drill carriages to the end of an excavator boom, and this can be seen in principle from Japanese patent specification 3-151493. All the known designs have in common that the drill carriage can only be pivoted or placed to a limited extent, in particular it is not possible to make horizontal bores close to the ground. However, this is necessary in the case of tunnel feed or also with cunettes. The invention is therefore based on the object of providing a drill carriage of the type mentioned at the beginning, by means of which drill holes can be produced at any point and in any direction.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zum Anbau an einen Baggerausleger an dessen Kupplung das eingesetzte Drehgelenk für eine Roll-over-Bewegung von 360° ausgelegt ist, wobei an der der Kupplung abgewandten Seite des Roll-over-Drehgelenkes die schwenkbare Haltung der Bohrlafette angebracht ist. Durch das Zusammenspiel von Bewegung des Baggerauslegers, 360° Möglichkeit einer Roll-over-Bewegung und der schwenkbaren Halterung ist es möglich, sowohl vertikal als auch horizontal zu bohren, wobei aufgrund des Drehgelenks für die Roll-over-Bewegung auch nahe dem Boden gebohrt werden kann.According to the invention, this object is achieved in that, for attachment to an excavator boom on its coupling, the rotary joint used is designed for a roll-over movement of 360 °, the pivotable position of the drill carriage on the side of the roll-over rotary joint facing away from the coupling is appropriate. The interplay of the movement of the excavator boom, 360 ° possibility of a roll-over movement and the swiveling holder make it possible to drill both vertically and horizontally, whereby drilling is also carried out near the ground for the roll-over movement can.
Beim Anbringen von Bohrlöchern in Künetten, bei welchen der Bagger mit den Baggerraupen beidseits der Künette aufsteht, ergibt sich zusätzlich auch noch das Problem, daß bei den bekannten Einrichtungen die Bohrlafetten nicht nahe genug an bereits bestehende Künettenwandungen herangebracht werden können, wobei eine Horizontalbohrung am Boden einer Künette bzw. entlang der Künettenwandungen auch nicht möglich ist. Vorteilhafterweise kann zur Behebung der vorstehenden Nachteile bei einem parallel zur Führungsachse angeordneten Drehgelenk der schwenkbaren Halterung die Achse des Roll-over-Drehgelenkes schräg zu jener des Drehgelenkes der schwenkbaren Halterung verlaufen. Damit wird eine sehr raumsparende und schmale Ausbildung erzielt, die entlang beider Künettenwandungen bohren kann, und zwar sowohl horizontal als auch vertikal. Dadurch kann das Auftreten von Stufungen innerhalb der Künettenwandung vermieden werden, wobei die nächste Reihe an zu bohrenden Bohrlöchern schräg nach außen gebohrt wird, sodaß nach Durchführung der Sprengung der untere Teil der Künetten genauso breit wie der obere Bereich ist. Um eine gleichmäßige Ausrichtung der Bohrlafette nach allen Richtungen zu erreichen, hat es sich als vorteilhaft erwiesen, wenn die Achsen der beiden Drehgelenke zueinander einen Winkel von 45° einschließen. In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargelegt.When drilling holes in the tunnels, in which the excavator with the excavator caterpillars stands on both sides of the bezel, there is also the additional problem that, in the known devices, the drilling racks cannot be brought close enough to the existing wall of the trough, with a horizontal hole on the ground a bezel or along the bezel walls is also not possible. In order to eliminate the above disadvantages, the axis of the roll-over swivel joint can run obliquely to that of the swivel joint of the swivel holder in the case of a swivel joint of the swivel bracket arranged parallel to the guide axis. This results in a very space-saving and narrow design, which can drill along both wall walls, both horizontally and vertically. In this way, the occurrence of steps within the wall of the well can be avoided, the next row of boreholes to be drilled being drilled out at an angle, so that after the blasting has been carried out, the lower part of the wells is as wide as the upper area. In order to achieve a uniform alignment of the drill carriage in all directions, it has proven to be advantageous if the axes of the two swivel joints form an angle of 45 ° to one another. An exemplary embodiment of the subject matter of the invention is shown in the drawing.

Bei allen Darstellungen ist der eigentliche Baggerausleger nicht dargestellt, um eine einfache Darstellung zu erzielen. Die Bohrlafette wird am Baggerausleger über eine Kupplungseinrichtung 1 angebracht. Die Kupplungseinrichtung 1 ist an einer Halterung 2 vorgesehen, welche seitlich an einer Führung 3 der Bohrlafette angreift. An dieser Führung 3 ist ein Bohrantrieb vorgesehen, wobei die Führung 3 über Gleitschuhe 5 an der Halterung 2 verschiebbar geführt ist. Die Führung 3, welche mit dem Bohrantrieb 4 fix verbunden ist, wird über einen Hydraulikantrieb 14 in Längsrichtung der Führungslängsachse 3' verschoben.In all of the representations, the actual excavator boom is not shown in order to achieve a simple representation. The drill carriage is attached to the excavator boom via a coupling device 1. The coupling device 1 is provided on a holder 2, which acts laterally on a guide 3 of the drill carriage. A drill drive is provided on this guide 3, the guide 3 being guided displaceably on the holder 2 via sliding shoes 5. The guide 3, which is fixedly connected to the drilling drive 4, is displaced via a hydraulic drive 14 in the longitudinal direction of the longitudinal guide axis 3 '.
Zwischen den Gleitschuhen 5 und der K"t>plung 1 zum Baggerausleger ist einBetween the slide shoes 5 and the clutch 1 to the excavator boom there is a
Drehgelenk 6 in der Halterung vorgesehen, wt. ie ein Verschwenken der Führung 3 parallel zu ihrer Führungslängsachse 3' in bezug auf die Kupplung 1 zum Baggerausleger ermöglicht. Diese Verschwenkung erfolgt dabei um die zurSwivel joint 6 is provided in the holder, which enables pivoting of the guide 3 parallel to its longitudinal guide axis 3 'with respect to the coupling 1 to the excavator boom. This pivoting takes place around the
Führungslängsachse 3' parallele Drehachse 7 des Drehgelenks 6.Longitudinal guide axis 3 ′ parallel axis of rotation 7 of the swivel joint 6.
In der Halterung 2 ist noch ein weiteres Drehgelenk 8 vorgesehen, dessenA further swivel joint 8 is provided in the holder 2

Vorliegend beträgt der Winkel zwischen den beiden genannten Drehachsen 45°, wobei von der Kupplung 1 zum Baggerausleger her gesehen, die Drehachse 9 schräg nach unten weist.In the present case, the angle between the two mentioned axes of rotation is 45 °, the axis of rotation 9 pointing obliquely downward as seen from the coupling 1 to the excavator boom.
Das erstgenannte Drehgelenk 6 ist dabei so ausgelegt, daß eine Schwenkbewegung von wenigstens 180° um die Drehachse 7 erfolgen kann. Das Drehgelenk 8 hingegen ist für eine Roll-over-Bewegung um 360° ausgelegt, wobei in diesem Drehgelenk 8 ein hydraulischer Drehantrieb vorgesehen ist, der also die Verdrehung ohne Begrenzung ermöglicht.The first-mentioned swivel joint 6 is designed so that a pivoting movement of at least 180 ° about the axis of rotation 7 can take place. The swivel joint 8, on the other hand, is designed for a roll-over movement through 360 °, wherein in This rotary joint 8 is provided with a hydraulic rotary drive, which therefore enables rotation without limitation.

Dann wird z.B. bei einer bereits vorhandenen Künette, welche in dem Gestein 13 eingebracht und mittels eines Grabenverbaus 12 gesichert ist, die Bohrlafette abgesenkt, wobei sie dann durch Verschwenken um das Drehgelenk 6 in Richtung zu der Künettenwandung bewegt wird, an welcher die Bohrungen anzubringen sind. Das endgültige Heranbewegen an die10 excavator booms attached. Then e.g. in the case of an already existing crib, which is introduced into the rock 13 and secured by means of a trench sheeting 12, the drill carriage is lowered, wherein it is then moved by pivoting about the swivel joint 6 in the direction of the cuvette wall to which the holes are to be drilled. The final move towards the
15 Künettenwandung kann erforderlichenfalls durch Verschwenken des Oberwagens des Baggers erfolgen. Dann wird mittels des Bohrantriebes 4 die in der unteren Bohrstangenführung 10 gehalterte Bohrstange in das Gestein eingebracht und eine Reihe von Bohrungen vorgenommen. Nach Beendigung der Bohrungsarbeiten auf einer Seite werden nach Verschwenken der Bohrlafette um das Drehgelenk 6 um15 The wall of the collar can be made, if necessary, by swiveling the upper structure of the excavator. Then the boring bar held in the lower boring bar guide 10 is introduced into the rock by means of the drilling drive 4 and a series of bores are made. After completion of the drilling work on one side after pivoting the drill carriage around the swivel 6
20 180° die Bohrungen analog auf der gegenüberliegenden Seite vorgenommen. Um bei diesen Bohrungen zu vermeiden, daß am Boden der bereits bestehenden Künette eine Abstufung vorliegt, da aufgrund der Bohrstangenführung und des Bohrantriebes die Bohrstange nicht unmittelbar unterhalb der Wandung eingebracht werden kann, wird die Bohrlafette, nämlich ihre Führung 3, um das Drehgelenk 8 verschwenkt, wobei20 180 ° the holes are made analogously on the opposite side. In order to prevent these holes from having a step at the bottom of the already existing bezel, since the drill rod cannot be inserted directly below the wall due to the drill rod guide and the drill drive, the drill carriage, namely its guide 3, is pivoted about the swivel joint 8 , in which
25 ein Schwenkwinkel von einigen Grad ausreicht, um dadurch dann ein Bohrloch schräg einbringen zu können. Damit kann die Breite der Künette gehalten werden, was den wesentlichen Vorteil hat, daß insbesondere bei Tiefkünetten, deren Grund mehrere Meter unter der Oberfläche liegt, die Breite der Künette am oberen Rand nicht größer sein muß als die Künette im unteren Bereich.25 a swivel angle of a few degrees is sufficient to be able to then insert a borehole at an angle. This allows the width of the bezel to be maintained, which has the significant advantage that, particularly in the case of deep cutters, the bottom of which is several meters below the surface, the width of the bezel at the upper edge need not be greater than the bottom of the bezel.
