Description

Die Erfindung bezieht sich auf einen Bohrarm, insbesondere für den Untertagbau, z.B. für eine Schrämmaschine.The invention relates to a drilling arm, in particular for underground construction, e.g. for a cutting machine.

Es sind verschiedene Anordnungen von Mannkörben bei Bohrwagen bekannt. So wird in der US-PS 4 108 253 ein Bohrwagen mit einem Bohrarm beschrieben, der einen am Bohrwagen gleitend höhen- und seitenverschieblich befestigten Mannkorb aufweist, der ein Dach mit daran befestigter Führung für den Bohrstahl trägt. In der US-PS 3 967 686 wird ein ähnlicher Bohrwagen beschrieben, wobei dieser mehrere Arme aufweist. Einer der Arme trägt eine Bohrmaschine und ein weiterer einen Mannkorb, welcher für einen Bedienungsmann dient, der die Bohrlöcher mit Sprengstoff lädt. Der Mannkorb weist weiters einen Dorn auf, welcher während des Bohrens gegen den Fels gepreßt wird, wobei auch eine Führung für den Bohrstahl vorgesehen sein kann. Nachdem der Bohrstahl in den Felsen eingedrungen ist, wird die Führung für denselben verfahren.Various arrangements of man baskets in drilling trucks are known. For example, in US Pat. No. 4,108,253, a drilling rig with a drilling arm is described, which has a man basket that is slidably attached to the drilling rig in a height and side-sliding manner and that carries a roof with a guide for the drilling steel attached to it. U.S. Patent 3,967,686 describes a similar drill car having multiple arms. One of the arms carries a drill and another carries a man's basket, which is used by an operator who loads the boreholes with explosives. The man basket also has a mandrel, which is pressed against the rock during drilling, wherein a guide for the drill steel can also be provided. After the drill steel has penetrated the rock, the guide is moved for it.

In der GB-PS 1 492 735 ist ein Bohrwagen beschrieben, der eine höhenveränderliche Plattform aufweist, welche einen Bohrarm mit Bohrmaschine und einen Arm für einen Mannkorb trägt, wobei beide Arme unabhängig voneinander gesteuert werden können, um die Einbringung des Sprengstoffes in ein Bohrloch leichter bewerkstelligen zu können.GB-PS 1 492 735 describes a drilling vehicle which has a height-adjustable platform which carries a drilling arm with a drilling machine and an arm for a man's basket, both arms being able to be controlled independently of one another in order to facilitate the introduction of the explosive into a borehole more easily to be able to accomplish.

Bei Bohrmaschinen, sei es zum Bohren von Ankerlöchern oder Sprenglöchern, ist es von hoher Bedeutung, daß einerseits die Löcher an den bestimmten erwünschten Stellen angesetzt werden und daß die Ausrichtung derselben mit der gewünschten Richtung übereinstimmt. Für diesen Zweck sind die Bohrarme heb-, senk- und schwenkbar ausgebildet, wobei diese sodann über einen geeigneten Kopf die Bohrmaschine tragen. Es kann nun auch erwünscht sein, daß unmittelbar vor oder nach dem Bohrvorgang ein Bedienungsmann in Nähe des Bohrloches bringbar ist, da dieser beispielsweise die Sprengladungen oder auch den Klebemörtel für die Anker in die Bohrlöcher einbringen muß. Für diesen Zweck ist es bereits bekannt geworden, auf dem Bohrausleger einen Mannkorb zu befestigen. Mit diesem Mannkorb ist nun direkt ein Lafettenhalter mit zugehöriger Lafette einer Bohrmaschine verbunden. Die Lafette ist um eine Achse, die etwa in Ebene der Plattform des Mannkorbes liegt, drehbar. Durch einen derartigen Bohrarm wird es zwar ermöglicht, daß ohne eine eigene Hebebühne der Bergmann direkt zur Mündung der Bohrlöcher gelangen kann, jedoch muß dieser entweder während des Bohrvorganges auf der Plattform verbleiben, wodurch eine Gefährdung, sei es durch die Bohrmaschine oder durch herabfallendes Gestein eintreten kann oder es muß jeweils nach einem Bohrloch die Plattform abgesenkt werden, worauf der Mann die Plattform besteigen kann, dieser wird sodann bis zum Bohrloch verbracht, verrichtet dort seine Arbeit, worauf die Plattform erneut wieder abgesenkt werden muß um für die weitere Bohrung wieder in Arbeitsstellung verbracht zu werden.In drilling machines, be it for drilling anchor holes or blast holes, it is of great importance that on the one hand the holes at the specific desired locations be set and that the orientation of the same coincides with the desired direction. For this purpose, the drilling arms can be raised, lowered and pivoted, and they then carry the drilling machine via a suitable head. It may now also be desirable for an operator to be able to be brought into the vicinity of the borehole immediately before or after the drilling operation, since the operator has to insert the explosive charges or the adhesive mortar for the anchors into the boreholes, for example. For this purpose, it has already become known to attach a man's basket to the drill boom. With this man basket, a carriage holder with the associated carriage of a drill is now directly connected. The carriage is rotatable about an axis that lies approximately in the plane of the platform of the man basket. Such a drilling arm makes it possible for the miner to get directly to the mouth of the boreholes without his own lifting platform, but this must either remain on the platform during the drilling process, thereby endangering whether it is caused by the drilling machine or by falling rocks The platform can or must be lowered after a borehole, whereupon the man can climb the platform, which is then brought up to the borehole, does his work there, whereupon the platform must be lowered again in order for the further drilling to return to the working position to be spent.

Die vorliegende Erfindung hat sich zum Ziel gesetzt, einen Bohrarm zu schaffen, der die o.a. Nachteile vermeidet und es gestattet, den Bohrarm in einer Stellung sowohl beim Bohren als auch beim Laden des Bohrloches, sei es mit Sprengstoff od. dgl. zu belassen, ohne daß eine Gefährdung der Bedienungsmannschaft entsteht und wobei gleichzeitig eine leichte Positionierung der Bohrlafette bei genauer Einstellung derselben möglich ist.The present invention has set itself the goal of creating a drilling arm that avoids the above disadvantages and it allows the drill arm to be left in one position both when drilling and when loading the borehole, be it with explosives or the like, without endangering the operating team and, at the same time, making it easy to position the drill carriage with precise adjustment .

Der erfindungsgemäße Bohrarm, insbesondere für den Untertagebau, z.B. für eine Schrämmaschine mit einer Konsole, an welcher ein über Hydraulikzylinder heb-, senk- und schwenkbar gegebenenfalls teleskopierbarer Bohrausleger angelenkt ist, der einen Mannkorb sowie eine drehbar gelagerte Lafette mit Bohrmaschine trägt, besteht im wesentlichen darin, daß der Mannkorb über einen Tragarm mit dem heb-, senk- und schwenkbaren Bohrausleger verbunden ist und eine Parallelführung aufweist, wobei der heb-, senk- und schwenkbare Bohrausleger über einen Kopf, der eine Dreh- und Schwenkeinrichtung für die Bohrlafette aufweist,mit dieser verbunden ist, wobei vorzugsweise die Konsole entlang einer Längsverschiebebahn verschiebbar ist. Durch die derartig erreichte räumliche Trennung von Mannkorb und Bohrlafette kann einerseits der bedienende Mann außerhalb des Gefahrenbereiches gehalten werden, wobei eine volle Beweglichkeit der Bohrlafette gegeben ist.The drilling arm according to the invention, in particular for underground construction, e.g. For a cutting machine with a bracket, on which a telescopic drill boom, which can be raised, lowered and swiveled, is pivoted, which carries a man's basket and a rotatably mounted carriage with a drill, consists essentially in that the man's basket has a support arm with the liftable, lowerable and pivotable drill boom is connected and has a parallel guide, the liftable, lowerable and pivotable drill boom being connected to the drill carriage by a head, which preferably has a rotation and pivoting device for the drill carriage, preferably along the console a longitudinal displacement path is displaceable. The spatial separation of the man basket and the drill carriage achieved in this way allows the operator to be kept outside the danger zone, with full flexibility of the drill carriage.

Gemäß einem weiteren Merkmal der Erfindung weist die Parallelführung des Mannkorbes einen mit der Konsole und dem heb-, senk- und schwenkbaren Bohrausleger verbundenen hydraulischen Geberzylinden, der mit einem entsprechenden Stellzylinder des Mannkorbes verbunden ist, auf. Damit ist eine besonders einfache Parallelführung des Mannkorbes gegeben, die, was insbesondere für den Untertagewerkbau von besonderem Interesse ist, raumsparend und besonders störungssicher ist.According to a further feature of the invention, the parallel guidance of the man basket has a hydraulic master cylinder connected to the console and the lifting, lowering and pivoting drilling boom, which is connected to a corresponding actuating cylinder of the man basket. This results in a particularly simple parallel guidance of the man basket, which, which is of particular interest for underground construction, is space-saving and particularly fail-safe.

Beim Bohren in besonders brüchigem Gestein, oder wenn der Bohrarm auf einer anderen Arbeitsmaschine z.B. Voll-oder Teilschnittmaschine angeordnet ist, kann es von besonderem Interesse sein, wenn gemäß einem weiteren Merkmal der Erfindung der Mannkorb am Tragarm von einer Arbeits- in eine Parkstellung schwenkbar gelagert ist.When drilling in particularly fragile rock, or when the drilling arm is on another machine, e.g. If a full or partial cutting machine is arranged, it can be of particular interest if, in accordance with a further feature of the invention, the man basket is pivotally mounted on the support arm from a working position into a parking position.

Um ein leichtes Einsteigen in den Mannkorb zu ermöglichen, wobei gleichzeitig keine Behinderung der normalen Arbeit dadurch bedingt sein darf, kann erfindungsgemäß eine verschiebbare Einsteighilfe für den Mannkorb vorgesehen sein.In order to make it easy to get into the man basket, while at the same time no hindrance to normal work may be caused, a sliding entry aid for the man basket can be provided according to the invention.

Eine besonders platzsparende Konstruktion ergibt sich dann, wenn der mit dem heb-, senk- und schwenkbaren Bohrausleger verbundene Kopf einen um die Längsachse des Bohrauslegers drehbar gelagerten Schwenkkopf aufweist.A particularly space-saving construction results when the head connected to the lifting, lowering and pivoting drilling boom has a pivoting head which is rotatably mounted about the longitudinal axis of the drilling boom.

Ist der Schwenkkopf über eine zur Längsachse des Bohrauslegers ungefähr normal angeordneten Achse mit dem Bohrlafettenhalter verbunden, so ist eine besonders einfache Konstruktion für eine Vertikalausrichtung gegeben, wobei keine Störung durch den zusätzlich vorgesehenen Mannkorb bedingt ist.If the swivel head is connected to the drill mount holder via an axis which is approximately normal to the longitudinal axis of the drill arm, a particularly simple construction is provided for a vertical alignment, with no disruption caused by the additionally provided man basket.

Ist die Bohrlafette am Lafettenhalter schwenkbar gelagert, so ist noch eine weitere Möglichkeit zur Vertikal- bzw. Horizontalausrichtung gegeben, die insbesondere unter Berücksichtigung des Platzbedarfes, wie er z.B. bei der Anfertigung von horizontalen Sprenglöchern gegeben ist, besonders günstig Rechnung getragen wird.If the drill carriage is pivotally mounted on the carriage holder, there is still another possibility for vertical or horizontal alignment, which takes into account, in particular, the space required, as e.g. is given in the preparation of horizontal blast holes, is taken into account particularly cheaply.

Wenn die Bohrlafette am Lafettenhalter verschiebbar befestigt ist, so kann dadurch die Distanz zwischen Bohrloch und Mannkorb auf besonders einfache Art und Weise vergrößert werden.If the drill carriage is slidably attached to the carriage holder, the distance between the borehole and the man basket can be increased in a particularly simple manner.

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

Es zeigen Fig. 1 und 2 eine Schrämmaschine mit dem erfindungsgemäßen Bohrarm in Seitenansicht bzw. Draufsicht, die Fig. 3 und 4 einen Bohrarm mit Mannkorb und Bohrlafette und Fig. 5 einen Bohrarm mit Einsteighilfe.1 and 2 show a cutting machine with the drilling arm according to the invention in a side view or plan view, FIGS. 3 and 4 a drilling arm with man basket and drill carriage, and FIG. 5 a drilling arm with entry aid.

Bei der in den Fig. 1 und 2 dargestellten Schrämmaschine 1 ist ein Teilschrämkopf 2 vorgesehen, welcher in Draufsicht nicht dargestellt ist, sondern lediglich sein Schwenkbereich angeführt ist. Oberhalb des Schrämkopfes ist ein Bohrarm 3 angeordnet, der über eine Konsole 4 mit der Schrämmaschine 1 verbunden ist. An der Konsole ist ein heb-, senk- und schwenkbarer Bohrausleger 5 angeordnet. Die Heb- und Senkbewegung wird über einen schematisch dargestellten Hydraulikzylinder 6 und einen weiteren Hydraulikzylinder 7 bewerkstelligt. Wie insbesondere den Fig. 3 und 4 entnehmbar, ist der Bohrarm 5 teleskopierbar, wobei der Zylinder 8 ein- und ausfahrbar ist. Der Zylinder trägt an seinem der Konsole abgewandten Ende einen Flansch 9, welcher seinerseits einen Tragarm 10 für den Mannkorb 11 aufweist. Der Flansch trägt seinerseits einen Kopf 12, welcher über eine Dreh- und Schwenkeinrichtung die Bohrlafette 13 trägt. Mit der Konsole und dem Bohrausleger ist ein Geberzylinder 14 verbunden, der je nachdem, ob der Bohrausleger gehoben oder gesenkt wird, die Druckmediumzu-oder -abfuhr im Stellzylinder 15 und die Parallelführung des Mannkorbes steuert. Wie insbesondere der Fig. 3 entnehmbar, ist der Stellzylinder sowohl am Mannkorb 11 als auch am Tragarm 10 angelenkt. Der Kopf 12, weist einen Schwenkkopf 16 auf, der um die Längsachse a des Bohrauslegers drehbar gelagert ist. Der Schwenkkopf seinerseits trägt weiters eine Schwenkwelle 17 um welche der Lafettenhalter 18 drehbar ist. Der Lafettenhalter 18 kann entweder nur längsverschieblich oder auch um die Achse b verdrehbar mit der Lafette 13 verbunden sein. Die Lafette kann über einen Hydraulikzylinder 19 auf dem Lafettenhalter längsverschieblich sein.In the cutting machine 1 shown in FIGS. 1 and 2, a partial cutting head 2 is provided, which is not shown in plan view, but rather only shows its swivel range. A drilling arm 3 is arranged above the cutting head and is connected to the cutting machine 1 via a bracket 4. A lifting boom 5 which can be raised, lowered and pivoted is arranged on the console. The lifting and lowering movement is accomplished via a schematically represented hydraulic cylinder 6 and a further hydraulic cylinder 7. As can be seen in particular from FIGS. 3 and 4, the drilling arm 5 is telescopic, the cylinder 8 being retractable and extendable. At its end facing away from the console, the cylinder has a flange 9, which in turn has a support arm 10 for the man basket 11. The flange in turn carries a head 12 which carries the drilling mount 13 via a rotating and swiveling device. A master cylinder 14 is connected to the console and the drill boom, which controls the pressure medium supply or discharge in the actuating cylinder 15 and the parallel guidance of the man basket, depending on whether the drill boom is raised or lowered. As can be seen in particular from FIG. 3, the actuating cylinder is articulated both on the man basket 11 and on the support arm 10. The head 12 has a swivel head 16 which is rotatably mounted about the longitudinal axis a of the drill arm. The pan head in turn also carries a pivot shaft 17 about which the carriage holder 18 is rotatable. The carriage holder 18 can either be connected to the carriage 13 only in a longitudinally displaceable manner or also rotatable about the axis b. The carriage can be longitudinally displaceable on the carriage holder via a hydraulic cylinder 19.

Wie aus Fig. 5 ersichtlich kann der Mannkorb am Tragarm 10 um eine in diesem gelagerte Welle 20 von einer Arbeitsstellung A in eine Parkstellung P (strichpunktiert dargestellt) über einen Hydraulikzylinder 21, welcher am Tragarm und am Mannkorb angelenkt ist, verschwenkt werden. Weiters kann, wie schematisch in Fig 5 dargestellt, eine Einsteighilfe 22 vorgesehen sein, die z.B. in Form einer parallel zum Mannkorb verschiebbaren Plattform ausgebildet ist.As can be seen from FIG. 5, the man basket on the support arm 10 can be pivoted about a shaft 20 mounted in it from a working position A to a parking position P (shown in broken lines) via a hydraulic cylinder 21 which is articulated on the support arm and on the man basket. Furthermore, as shown schematically in FIG. 5, an entry aid 22 can be provided which e.g. is designed in the form of a platform which can be moved parallel to the man basket.

Wird nun mit einer Schrämmaschine unter Tag gearbeitet, so wird der Bohrarm samt Mannkorb, wie in Fig. 1 deutlich ersichtlich entlang einer Längsverschiebebahn 23 in eine strichpunktiert dargestellte Ruhestellung verbracht. In dieser Ruhestellung ist keine arbeitsmäßige Behinderung des Schrämkopfes gegeben. Soll nun der Ausbau der Strecke durch Ankersetzen erfolgen, so wird der Bohrarm entlang der Längsverschiebebahn 23 in die Arbeitsstellung verbracht, worauf die Plattform 22 ausgefahren wird und der Mann in den in Parkstellung befindlichen Mannkorb einsteigen kann. Sodann wird der heb-, senk- und schwenkbare Bohrausleger in die Arbeitsstellung gebracht, wobei gegebenenfalls der Bohrausleger noch ausgefahren wird. In dieser Stellung erfolgt sodann das Ausrichten der Bohrlafette über die Dreh- und Schwenkeinrichtung des Kopfes. Die radiale Ausrichtung der Bohrlafette erfolgt durch Schwenken um die Achse b. Der Mannkorb kann entweder in der Arbeits- oder in der Parkstellung verbleiben, je nachdem ob beispielsweise mit Wasserspülung oder ohne Wasserspülung gebohrt wird. Nachdem das Bohrloch fertig ausgeführt ist, wird die Bohrlafette aus dem unmittelbaren Bereich herausgeschwenkt, worauf das Bedienungsorgan entweder eine Sprengladung oder z.B. einen Kunststoffkleber für einen Anker in das Bohrloch einbringen kann.If work is now carried out underground with a cutting machine, the drilling arm together with the man's basket, as can clearly be seen in FIG. In this rest position there is no working disability of the cutting head. If the route is now to be expanded by anchoring, the drilling arm is brought into the working position along the longitudinal displacement path 23, whereupon the platform 22 is extended and the man can climb into the man basket in the park position. The lifting, lowering and swiveling drill boom is then brought into the working position, with the drill boom still being extended if necessary. In this position the drill carriage is then aligned using the rotating and swiveling device of the head. The drill carriage is aligned radially by swiveling around the axis b. The man basket can either remain in the working or in the park position, depending on whether drilling is carried out, for example, with water flushing or without water flushing. After the borehole has been completed, the drill carriage is pivoted out of the immediate area, whereupon the operating member can either insert an explosive charge or, for example, a plastic adhesive for an anchor into the borehole.
