Description

Die Erfindung bezieht sich auf einen Bohrarm, wie er auf Wagen oder dgl. im Über- und Untertagebau, insbesondere Bergbau Verwendung findet. Derartige Bohrarme werden nicht nur zur Anfertigung von Sprenglöchern sondern auch von Bohrlöchern für Anker verwendet. Werden Anker gesetzt, so kann der Bohrarm gleichzeitig auch als Träger für eine Ankersetzvorrichtung dienen.The invention relates to a drilling arm, as it is used on wagons or the like. In surface and underground mining, in particular mining. Such drilling arms are used not only to make blast holes but also to drill holes for anchors. If anchors are set, the drilling arm can also serve as a support for an anchor setting device.

Von hoher Bedeutung ist die Beweglichkeit von Bohrarmen, da das Bestreben besteht, von einer Stellung aus eine möglichst hohe Anzahl von Bohrlöchern ausführen zu können, wobei einerseits eine genaue Positionierung des Bohrers am Fels möglich sein muss, und andererseits die Ausrichtung der den Bohrer tragenden Bohrlafette entsprechend dem erwünschten Winkel gewährleistet sein muss. Hiezu ist es erforderlich, dass einerseits eine relativ hohe Anzahl von Gelenken im Bohrausleger vorgesehen ist, und andererseits muss eine besonders robuste Konstruktion gewählt werden, damit keine Positionsänderungen der Lafette während des Bohrens eintritt, in welchem Falle es entweder zu einer Überbeanspruchung des Bohrers oder sogar zu dessen Bruch kommt.The mobility of the drill arms is of great importance, since the aim is to be able to drill as many holes as possible from one position, whereby on the one hand it must be possible to position the drill precisely on the rock and on the other hand the alignment of the drill carriage carrying the drill must be guaranteed according to the desired angle. For this purpose, it is necessary that, on the one hand, a relatively high number of joints are provided in the drill boom, and, on the other hand, a particularly robust construction must be chosen so that no changes in the position of the mount occur during drilling, in which case either the drill is overstressed or even comes to break.

Es ist bereits aus der Praxis ein Bohrarm bekannt, welcher eine Konsole aufweist, die zum Verbinden desselben mit dem Wagen vorgesehen ist, diese Konsole weist Anlenkungen für einen Bohrausleger auf, welcher über einen Heb- und Senkzylinder sowie einen Schwenkzylinder, die ebenfalls an der Konsole angelenkt sind, bewegbar ist. Dieser Bohrausleger weist an seinem distalen Ende einen Drehmotor auf, welcher einen Gabelkopf trägt, der seinerseits über einen Arm eine Schwenkwelle trägt, die ihrerseits den Lafettenhalter mit Lafette aufweist. Ein derartiger Bohrarm zeichnet sich durch eine besonders einfache Konstruktion aus, die gleichzeitig die Möglichkeit der verschiedensten Positionierungen bietet. Nachteilig bei einem Bohrarm dieser Bauart ist, dass ein besonderer Platzbedarf beim Positionieren des Bohrgerätes gegeben ist.It is already known from practice a drilling arm, which has a bracket that is provided for connecting the same to the carriage, this bracket has articulations for a drilling boom, which has a lifting and lowering cylinder and a swivel cylinder, which are also on the console are articulated, is movable. This drill boom has at its distal end a rotary motor which carries a fork head which in turn carries a pivot shaft via an arm which in turn has the mount holder with mount. Such a drilling arm is characterized by a particularly simple construction, which at the same time offers the possibility of various positions. A disadvantage of a drilling arm of this type is that there is a particular need for space when positioning the drilling device.

Die vorliegende Erfindung hat sich zur Aufgabe gestellt, einen Bohrarm zu schaffen, der es erlaubt, beidseitig des Bohrauslegers die Lafette anzuordnen, wobei in beiden Lafettenstellungen eine vollkommene Äquivalenz in der Positionierung der Lafette, insbesondere in den beiden Endstellungen gegeben sein soll.The object of the present invention is to create a drilling arm which allows the mount to be arranged on both sides of the drill arm, with a complete equivalence in the positioning of the mount, in particular in the two end positions, being provided in both mount positions.

Der erfindungsgemässe Bohrarm mit einer Konsole, einem an dieser angelenkten, gegebenenfalls teleskopierbaren Ausleger, der über einen Heb-Senk- und einen Schwenzylinder bewegbar ist, wobei der Ausleger an seinem distalen, gegebenenfalls um die Längsachse des Auslegers drehbaren, Ende eine, z.B. in einem Gabelkopf, gelagerte Schwenkachse trägt, an welcher ein mittels Zylinder od. dgl. schwenkbarer Träger gelagert ist, in dem eine im wesentlichen normal zur Schwenkachse angeordnete Trägerwelle gelagert ist, die den Bohrlafettenhalter mit Bohrlafette, Bohreinrichtung und gegebenenfalls Ankersetzeinrichtung trägt, besteht im wesentlichen darin, dass an der Trägerwelle ein Arm gelagert ist, welcher an seinem distalen Ende eine weitere Welle aufweist, die mit dem Lafettenhalter verbunden ist, wobei die Trägerwelle und die weitere Welle im wesentlichen zueinander parallel angeordnet sind. Mit einer derartigen Anordnung ist auf überraschend einfache Art und Weise die Möglichkeit gesichert, dass die Bohrlafette beidseits des Bohrauslegers angeordnet sein kann. Für das Bewegen der Lafette von einer Seite des Bohrauslegers zur anderen Seite des Bohrauslegers ist es lediglich erforderlich, dass der Arm, welcher in der Trägerwelle gelagert ist, auf die andere Seite des Bohrauslegers geschwenkt wird, wobei nacheinander oder gleichzeitig die Bohrlafette um die weitere Welle ebenfalls um denselben Winkel geschwenkt wird.The drilling arm according to the invention with a bracket, an articulated, optionally telescopic boom, which can be moved via a lifting and lowering cylinder and a swing cylinder, the boom at its distal end, which can be rotated about the longitudinal axis of the boom, e.g. in a fork head, carries a pivot axis, on which a carrier which can be pivoted by means of a cylinder or the like is mounted, in which a carrier shaft which is arranged essentially normal to the pivot axis and which carries the drill carriage holder with drill carriage, drilling device and, if appropriate, anchor setting device, essentially exists in that an arm is mounted on the carrier shaft, which has a further shaft at its distal end, which is connected to the mount holder, the carrier shaft and the further shaft being arranged essentially parallel to one another. With such an arrangement, the possibility is secured in a surprisingly simple manner that the drill mount can be arranged on both sides of the drill arm. To move the carriage from one side of the drill boom to the other side of the drill boom, it is only necessary that the arm, which is mounted in the carrier shaft, is pivoted to the other side of the drill boom, the drill carriage being successively or simultaneously around the further shaft is also pivoted through the same angle.

Eine besonders gute Beweglichkeit ist dann gegeben, wenn die weitere Welle und die Trägerwelle je in einem, vorzugsweise hydraulischen Drehzylinder angeordnet sind.A particularly good mobility is given when the further shaft and the carrier shaft are each arranged in a preferably hydraulic rotating cylinder.

Ist der Arm von einer Endstellung, in welcher dieser im wesentlichen normal zur Auslegerachse angeordnet ist, in die andere Endstellung um etwa 180° schwenkbar, so kann die Bohrlafette besonders weit beidseitig des Auslegers angeordnet werden.If the arm can be swiveled by approximately 180 ° from one end position, in which it is arranged essentially normal to the boom axis, into the other end position, the drill carriage can be arranged particularly far on both sides of the boom.

Ist der Lafettenhalter aus seiner einen Endstellung, in welcher dieser im wesentlichen normal zum Arm angeordnet ist, in die andere Endstellung um 180° schwenkbar, so kann die Bohrlafette jede beliebige Winkellage einnehmen.If the mount holder can be swiveled through 180 ° from its one end position, in which it is arranged essentially normal to the arm, into the other end position, then the drill mount can assume any angular position.

Im folgenden wird die Erfindung anhand der Zeichnungen näher erläutert.The invention is explained in more detail below with reference to the drawings.

Es zeigen Fig. 1 einen Bohrarm, der auf einem Bohrwagen montiert ist, in Seitenansicht und Fig. 2 den Bohrarm gemäss Fig. 1 in Draufsicht.1 shows a drilling arm which is mounted on a drilling carriage, in a side view and FIG. 2 shows the drilling arm according to FIG. 1 in a top view.

Der in Fig. 1 teilweise dargestellte Wagen 1 trägt eine Konsole 2, die Laschen 3 aufweist, an welchen der Ausleger 4, der Heb- und Senkzylinder 5 und der Schwenkzylinder 6 angelenkt sind. Im distalen Ende des Auslegers 4 ist ein Drehzylinder 7 vorgesehen, der auf einem nicht-dargestellten Teleskopauszug im Ausleger befestigt ist. Der Drehzylinder trägt seinerseits einen weiteren Auslegerteil 8, der an seinem distalen Ende einen Gabelkopf 9 trägt. Im Gabelkopf 9 ist eine Welle 10 gelagert, an welcher ein Träger über einen Zylinder 12 schwenkbar gelagert ist. Der Träger 11 weist seinerseits einen Drehzylinder 13 auf, in welchem eine Trägerwelle 14 vorgesehen ist. An der Trägerwelle 14 ist - wie in Fig. 2 besonders deutlich ersichtlich - ein Arm 15 um 180° drehbar gelagert, der an seinem distalen Ende einen Drehzylinder 16 mit weiterer Welle 17, die ihrerseits den Lafettenhalter 18 trägt, der um 180° drehbar ist, vorgesehen. Am Lafettenhalter ist die Lafette 19 befestigt, entlang welcher das Bohraggregat 20, gegebenenfalls mit Ankersetzvorrichtung verschiebbar ist. Bei der Längsverschiebung des Bohraggregates wird der Bohrstahl 21 durch die Führung 22 hindurch in den Fels getrieben, wobei sich die Lafette mit dem Dorn 23 am Felsen abstützt.The carriage 1 partially shown in FIG. 1 carries a bracket 2 which has tabs 3 to which the boom 4, the lifting and lowering cylinder 5 and the swivel cylinder 6 are articulated. In the distal end of the boom 4, a rotary cylinder 7 is provided, which is fastened on a telescopic extension (not shown) in the boom. The rotary cylinder in turn carries a further boom part 8, which carries a fork head 9 at its distal end. In the fork head 9, a shaft 10 is mounted, on which a carrier is pivotally mounted via a cylinder 12. The carrier 11 in turn has a rotary cylinder 13 in which a carrier shaft 14 is provided. On the carrier shaft 14, as can be seen particularly clearly in FIG. 2, an arm 15 is rotatably mounted by 180 °, which has at its distal end a rotary cylinder 16 with a further shaft 17, which in turn carries the mount holder 18, which can be rotated by 180 ° , intended. The carriage 19 is fastened to the carriage holder, along which the drilling unit 20 can be displaced, optionally with an anchor-setting device. During the longitudinal displacement of the drilling unit, the drilling steel 21 is driven into the rock through the guide 22, the carriage being supported on the rock by the mandrel 23.

Wie in Fig. 2 ersichtlich, sind beidseits der Konsole Stützen 24, 25 vorgesehen, die die Konsole am Boden 26 abstützen.As can be seen in FIG. 2, supports 24, 25 are provided on both sides of the console, which support the console on the floor 26.

Soll nun die Lafette von einer Seite des Bohrauslegers zur anderen Seite desselben verbracht werden, so wird der Drehzylinder 13 betätigt, wodurch der Arm 15 von seiner einen Endstellung links vom Ausleger in die andere Endstellung rechts vom Ausleger (in Fig. 2 strichliert dargestellt) zu liegen kommt. Gleichzeitig mit dieser Drehbewegung des Armes 15 wird eine gegengleiche Drehbewegung im Drehzylinder 16 durchgeführt, sodass die Lafette weiterhin parallel zum Ausleger angeordnet sein kann.If the carriage is now to be moved from one side of the drill arm to the other side of the same, the rotary cylinder 13 is actuated, causing the arm 15 to move from its one end position to the left of the boom into the other end position to the right of the boom (shown in dashed lines in FIG. 2) comes to lie. Simultaneously with this rotational movement of the arm 15, an opposite rotational movement is carried out in the rotating cylinder 16, so that the mount can continue to be arranged parallel to the boom.
