Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Bohren in Gestein, Erz od. dgl., z.B. zum Vortrieb, Tunnelbau usw. mit einem fahrbaren gelenkten, insbesondere knickgelenkten Wagen.The invention relates to a device for drilling in rock, ore or the like, e.g. for driving, tunnel construction etc. with a mobile steered, especially articulated car.

Beim bergmännischen Abbau von Erzen und dgl. und auch beim Tunnelbau, Kanalbau usw. wechseln zwei verschiedene Vorgänge miteinander ab. Einerseits muß das Gestein od. dgl. herausgebrochen, geschrämt od. dgl. werden, oder es werden beispielsweise Sprenglöcher angefertigt, wonach die Sprengung durchgeführt wird, worauf das gelockerte Gestein entfernt werden muß. Zu diesem Zeitpunkt besteht jedoch der gesprengte Tunnel od. dgl. lediglich aus Gestein, wobei der Zusammenhalt des Tunnels nur durch die Gewölbewirkung gegeben ist und jegliche tektonischen Unregelmäßigkeiten den weiteren Bestand des Stollens, Tunnels, od. dgl. voll gefährden. Dementsprechend ist es seit langem üblich,nachdem ein Teil des Stollens ausgebrochen wurde, diesen auszubauen, wobei ursprünglich Holzstempel und in jüngerer Zeit Stahltübbings Verwendung finden. Seit einiger Zeit findet die sogenannte Ankertechnik einen immer größeren Einsatzbereich zur Absicherung von Stollen. Hiebei wird so vorgegangen, daß nach Abschluß der Spreng- und Räumarbeiten in den gewachsenen Fels Bohrlöcher getrieben werden, die etwa normal zur Tangente im jeweiligen Tunnelprofil angeordnet sind, worauf Stahlanker, die an ihrem einen Ende ein Gewinde, eine Platte und eine Mutter tragen, im Bohrloch fixiert werden. Dieses Fixieren im Bohrloch kann entweder mit einem hydraulischen Bindemittel aber auch mit duroplastischen Bindemitteln oder dgl. erfolgen. Nachdem der Anker im Bohrloch beanspruchbar fixiert ist, wird die Schraubenmutter angezogen, sodaß über die zwischen Fels und Schraubenmutter befindliche Stahlplatte auf das Gestein eine Druckspannung aufgebracht wird, womit in vielen Fällen ein vollkommen ausreichender Ausbau des Tunnelstollens od. dgl. gegeben ist. Bislang wurde so vorgegangen, daß das Bohren der Sprenglöcher also jener Bohrlöcher, die in Vortriebsrichtung angeordnet,sind, und das Bohren der Ankerlöcher, deren Bohrrichtung etwa vertikal bzw. radial zur Vortriebsr-ichtung der Sprenglöcher ist, vollkommen unabhängig voneinander durchgeführt wurden, wobei aufgrund der unterschiedlichen Bohrrichtungen auch verschiedene Bohrwagen Verwendung gefunden haben.When mining ores and the like, and also when building tunnels, sewers, etc., two different processes alternate with one another. On the one hand, the rock or the like must be broken out, cut or the like, or blast holes are made, for example, after which the blasting is carried out, after which the loosened rock must be removed. At this time, however, the blown-up tunnel or the like consists only of rock, the cohesion of the tunnel being given only by the vault effect and any tectonic irregularities fully endanger the further existence of the tunnel, tunnel, or the like. Accordingly, it has been common practice for a long time after a part of the gallery to be broken out, using wooden stamps and, more recently, steel tubbing. For some time now, so-called anchor technology has been used for securing tunnels in ever greater numbers. Hiebei is proceeded in such a way that after the completion of the blasting and clearing work, boreholes are drilled into the grown rock, which are arranged approximately normal to the tangent in the respective tunnel profile, whereupon steel anchors, which have a thread, a plate and a nut at one end, be fixed in the borehole. This fixing in the borehole can be done either with a hydraulic binder, but also with thermosetting binders or the like. After the anchor is securely fixed in the borehole, the screw nut is tightened so that a compressive stress is applied to the rock via the steel plate located between the rock and the screw nut, which in many cases provides a completely sufficient expansion of the tunnel gallery or the like. So far, the procedure was such that the drilling of the blast holes, that is to say those holes which are arranged in the direction of advance, and the drilling of the anchor holes, the direction of which is approximately vertical or radial to the direction of advance of the blast holes, were carried out completely independently of one another the different drilling directions have also used different drilling rigs.

Die vorliegende Erfindung hat sich zum Ziel gesetzt, eine Vorrichtung zum Bohren in Gestein, insbesondere zum bergmännischen Vortriebzu schaffen, die es erlaubt, ohne großen Platzbedarf selbst bei einer Strecke mit ca. 5 m Breite und 4 m Höhe gleichzeitig Sprenglöcher und auch Ankerlöcher anzufertigen, wobei naturgemäß die Ankerlöcher in jenem Bereich getätigt werden, welcher vorhergehend durch die Spreng-und Räumarbeiten geschaffen wurde . Weiters soll sichergestellt sein, daß die Bedienungsorgane für die Bohrvorrichtungen, sei es für die Sprenglöcher als auch für die Ankerlöcher nicht in dem unabgesicherten Bereich hantieren müssen. Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, daß die Bohrvorrichtung einmal vorort gebracht, nicht mehr verfahren werden muß, sondern daß die entsprechenden Bewegungen der Bohraggregate unabhängig voneinander und gleichzeitig durchgeführt werden können, sodaß die Rüstzeiten und dgl. wesentlich verkürzt werden.The present invention has set itself the goal of providing a device for drilling in rock, in particular for mining work, which allows blast holes and anchor holes to be produced simultaneously without a large space requirement, even on a route with a width of approximately 5 m and a height of 4 m, the anchor holes are naturally made in the area which was previously created by the blasting and clearing work. Furthermore, it should be ensured that the operating elements for the drilling devices, be it for the blast holes or for the anchor holes, do not have to operate in the unsecured area. Another object of the present invention is that the drilling device is brought to the site once, no longer has to be moved, but that the corresponding movements of the drilling units can be carried out independently of one another and simultaneously, so that the set-up times and the like are significantly reduced.

Die erfindungsgemäße Vorrichtung zum Bohren in Gestein, Erz od. dgl., z.B.zum Vortrieb,Tunnelbau und dgl., mit einem fahrbaren gelenkten, insbesondere knickgelenkten, Wagen, heb- und senkbaren Abstützungen, welcher un- und/oder mittelbar mehrere, zumindest drei Bohrarme mit insbesondere drehbaren Konsolen aufweist, deren Bohrausleger schwenk-, heb- und senkbar und gegebenenfalls drehbar und/oder teleskopierbar ausgebildet sind, und die eine Bohrlafette mit Drehmotor, insbesondere Drehschlagmotor und Vorschubeinrichtung angelenkt tragen, und zumindest einer Druckmedium-,insbesondere Hydraulikversorgung, besteht im wesentlichen darin, daß zumindest ein Bohrarm, welcher gegebenenfalls eine kürzere und/oder teleskopierbare Lafette als die anderen Bohrarme aufweist, welcher zwischen zwei anderen am Wagen angeordnet ist, in Vortriebsrichtung ortsveränderlich, insbesondere un- bzw. mittelbar mit seiner Konsole entlang einer Verschiebebahn verschiebbar ist, wobei vorzugsweise die Verschiebebahn im wesentlichen parallel zur Sohle angeordnet ist. Durch das insbesondere knickgelenkte Fahrzeug mit heb-und senkbaren Abstützungen kann der Bohrwagen auch unter engsten Platzbedingungen in Arbeitsstellung verfahren werden, wobei durch die Abstützungen eine exakte Positionierung und Ausrichtung des Wagens gegeben ist. Da der zwischen zwei anderen am Wagen angeordnete Bohrarm mit Konsole in Vortriebsrichtung ortsveränderlich angeordnet ist, können aus einer Arbeitsstellung des Bohrwagens, aus welcher sämtliche Sprenglöcher angeordnet werden, alle oder im wesentlichen alle radial von der Vortriebsrichtung ausgehende Ankerlöcher und zwar in Abstand voneinander bezogen auf die Vortriebsrichtung gebohrt werden, wobei eine besonders störungsfreie Konstruktion dann gegeben ist, wenn der Bohrarm mit seiner Konsole entlang einer Verschiebebahn verschiebbar ist, die vorzugsweise im wesentlichen parallel zur Sohle anordenbar ist.The device according to the invention for drilling in rock, ore or the like, for example for driving, tunnel construction and the like, with a mobile steered, in particular articulated, Trolley, lifting and lowering supports, which directly and / or indirectly has several, at least three drilling arms with, in particular, rotatable brackets, the drill arms of which can be pivoted, raised and lowered and, if appropriate, rotated and / or telescoped, and which have a drilling mount Carrying the rotary motor, in particular the rotary impact motor and the feed device, and at least one pressure medium, in particular hydraulic supply, consists essentially in that at least one drilling arm, which may have a shorter and / or telescopic mount than the other drilling arms, which is arranged between two others on the carriage is movable in the direction of advance, in particular directly or indirectly with its bracket along a displacement path, wherein the displacement path is preferably arranged substantially parallel to the sole. Due to the articulated vehicle, in particular, with supports that can be raised and lowered, the drilling carriage can be moved into the working position even under the tightest of space conditions, the supports providing precise positioning and alignment of the carriage. Since the drill arm with bracket arranged between two other on the carriage is arranged so that it can be moved in the direction of advance, all or essentially all of the anchor holes radially emanating from the direction of advance can be separated from one working position of the drill carriage, from which all the blast holes are arranged Driving direction are drilled, a particularly trouble-free construction is given when the drilling arm with its bracket is displaceable along a displacement path, which can preferably be arranged essentially parallel to the sole.

Aus dem Tunnelbau wird eine Vorrichtung zum Vortreiben von Sprenglöchern bekannt, die eine Vielzahl von Bohrarmen trägt, wobei die seitlich angeordneten Bohrarme in Vortriebsrichtung telskopierbar sind. Eine derartige Vorrichtung ist jedoch keinenfalls zur Lösung der gestellten Aufgabe geeignet, da eine derartige Vorrichtung zu platzintensiv ist, und weiters die erforderlichen Bohrlöcher für eine Ankerung nicht durchgeführt werden können.From tunnel construction, a device for propelling blast holes is known which carries a plurality of drill arms, the laterally arranged drill arms being driven direction are telescopic. However, such a device is in no way suitable for solving the task, since such a device is too space-intensive and, furthermore, the drill holes required for anchoring cannot be carried out.

Ist/sind zusätzlich zu dem in Vortriebsrichtung ortsveränderlichen Bohrarm mit Konsole ein benachbarter, vorzugsweise zwei benachbarte, weitere Bohrarme in Vortriebsrichtung ortsveränderlich, insbesondere mit Konsole je entlang einer Verschiebebahn verschiebbar angeordnet, wobei vorzugsweise die Verschiebebahn im wesentlichen parallel zur Sohle vorgesehen ist, so können die einzelnen Bohrarme in ihre jeweiligen Positionen gebracht werden, ohne daß eine physische Behinderung vom anderen Bohrarm eintritt. Soll beispielsweise der mittlere Bohrarm eine SchwenkbewegUng ausführen, so können die beiden seitlich angeordneten Bohrarme entgegengesetzt der Vortriebsrichtung verfahren werden, womit eine volle Schwenkbewegung des Bohrarmes, welcher in der Regel zum Ankern dienen wird, durchgeführt werden kann, wonach die Bohrarme, welche für die Sprenglöcher dienen, erneut in Arbeitsstellung verfahrbar sind. Weiters kann der Wagen, zum reinen Transport bei nach hinten gefahrenen Bohrarmen eine wesentlich kürzere-Längserstreckung aufweisen, womit eine verbesserte Rähgierbarkeit gegeben ist.If, in addition to the drilling arm with bracket, which can be moved in the direction of advance, an adjacent, preferably two adjacent, further drilling arms can be moved in the driving direction, especially with a bracket, each being displaceable along a displacement path, the displacement path preferably being provided essentially parallel to the base, so that individual drill arms are brought into their respective positions without physical interference from the other drill arm. If, for example, the middle drilling arm is to perform a swiveling movement, the two laterally arranged drilling arms can be moved counter to the direction of advance, whereby a full swiveling movement of the drilling arm, which is usually used for anchoring, can be carried out, after which the drilling arms, which are used for the explosive holes serve again can be moved into the working position. Furthermore, the carriage can have a much shorter longitudinal extension for transport purposes only when the drilling arms are moved to the rear, which results in improved roughness.

Ist der zwischen zwei, vorzugsweise ortsveränderlichen anderen am Wagen in Vortriebsrichtung ortsveränderlich angeordnete Bohrarm in Richtung vorort näher zum Abbauort verfahrbar, so können auch Ankerlöcher in unmittelbarer Nähe vor der Ortsbrust in das Gestein getrieben werden, sodaß eine optimale Sicherung des Stollens gegeben ist.If the drill arm, which can be moved between two, preferably movable, on the carriage in the direction of advance, can be moved closer to the extraction site in the direction of the site, anchor holes can also be driven into the rock in the immediate vicinity of the face, so that the tunnel is optimally secured.

Sind zumindest drei in Vortriebsrichtung orientierte, vorzugsweise zueinander parallele Verschiebebahnen, entlang welcher Konsolen der Bohrarme verschiebbar sind, am Wagen angeordnet, wobei die von zwei benachbarten, insbesondere mittige Verschiebebahn weiter vorort reicht, als die beiden benachbarten, so ist eine besonders gute zeitliche Kombination für die Ausführung von den Bohrarbeiten für die Sprenglöcher und den Bohrarbeiten für die Ankerlöcher gegeben, wobei weiters eine besonders gute Absicherung im gesamten Bereich des Vortriebs gegeben ist. Eine besonders hohe Beweglichkeit des Bohrarms, mit welchem die Ankerlöcher ausgeführt werden sollen, ist dann gegeben, wenn bei nicht drehbarer Konsole der zwischen zwei anderen am Wagen angeordnete Bohrarm oberhalb des zugehörigen Heb-und Senkzylinders angelenkt ist, wobei zumindest ein benachbarter, insbesondere beide benachbarte Bohrarme unterhalb des zugeordneten Heb- und Senkzylinders angeordnet sind. Dadurch kann weiters bei beengtem Manipulationsplatz sine besonders leichte Ausrichtung der Bohrarme für die Sprenglöcher parallel und in Nähe der Sohle zur Sohle erreicht werden.Are at least three displacement tracks oriented in the direction of advance, preferably parallel to one another, along which brackets of the drilling arms can be displaced, on the carriage Arranged, the one of two adjacent, in particular central, displacement track extends further on site than the two neighboring ones, so there is a particularly good time combination for the execution of the drilling work for the blast holes and the drilling work for the anchor holes, furthermore a particularly good protection in the entire area of tunneling. A particularly high degree of mobility of the drilling arm, with which the anchor holes are to be made, is given when, in the case of a non-rotating bracket, the drilling arm arranged between two other carriages is articulated above the associated lifting and lowering cylinder, at least one adjacent, in particular both, adjacent Drilling arms are arranged below the assigned lifting and lowering cylinder. As a result, particularly easy alignment of the drilling arms for the blast holes can be achieved in parallel and near the sole to the sole when the manipulation space is restricted.

Ein besonders leichtes Hantieren, Austauschen von Geräten, Anziehen der Arbeitsmuttern, Montieren von Ankermatten und dgl. kann dann erreicht werden, wenn in Vortriebsrichtung des Wagens auf diesem hinter der Verschiebebahn eine Arbeitsbühne, insbesondere leicht lösbar, angeordnet ist.Particularly easy handling, replacing devices, tightening the working nuts, installing anchor mats and the like can be achieved if a working platform, in particular easily detachable, is arranged on the carriage in the direction of advance of the carriage.

Eine besonders einfache und vorteilhafte Konstruktion des Bohrarmes für die Ankerung ergibt sich dann, wenn der zwischen zwei anderen am Wagen in Vortriebsrichtung ortsveränderlich angeordnete Bohrarm eine Welle aufweist, die im wesentlichen normal zur Bohrauslegerlängsrichtung und im wesentlichen parallel zum Untergrund angeordnet ist, an welcher der Lafettenhalter mittel- bzw. unmittelbar befestigt ist.A particularly simple and advantageous construction of the drilling arm for anchoring is obtained if the drilling arm, which is arranged to be movable between two other on the carriage in the direction of advance, has a shaft which is arranged essentially normal to the longitudinal direction of the drill boom and essentially parallel to the ground on which the mount holder is is attached directly or indirectly.

Im folgenden wird die Erfindung anhand der Zeichnungen näher erläutert.

Der Wagen 1 weist eine Hydraulikversorgung 2 auf, und wird durch Räder 3 auf der Sohle getragen. Anstelle von Rädern können auch Raupen, Portale, Schienen usw. vorgesehen sein. An den jeweiligen Enden des Wagens sind heb- und senkbare Abstützungen 4 vorgesehen. Der Wagen ist, wie insbesondere aus Fig. 2 ersichtlich, knickgelenkt. Am in Vortriebsrichtung gemäß Pfeil a gesehen vorderen Ende sind drei Verschiebebahnen 5,6 und 7 vorgesehen. Diese Verschiebebahnen sind, wie insbesondere aus Fig. 1 ersichtlich, im wesentlichen parallel zur Sohle angeordnet. Auf der Verschiebebahn 6, die weiter vorort reicht als die Verschiebebahnen 5 und 7, ist eine Konsole 8 mit Bohrarm 9 angeordnet. Diese Konsole 8 ist entlang der Verschiebebahn 6 in und entgegen der Vortriebsrichtung ortsveränderlich. Entlang der Verschiebebahnen 5 und 7 sind die drehbaren Konsolen 10 und 11 längsverschieblich. Wie insbesondere aus Fig. 2 ersichtlich, kann die Konsole 8 der mittleren Verschiebebahn weiter vorort verschoben werden, als die Konsolen 10 und 11. Jeder Bohrarm ist teleskopierbar und weist eine nicht dargestellte Vorschubseinrichtong und einen Schlagbohr- bzw. Drehmotor auf, mit dem die jeweiligen Bohrstangen 12, 13 und 14 in das Gestein getrieben werden. An der Konsole 8 ist der Bohrarm 9 oberhalb dem zugehörigen Heb- und Senkzylinder 15 angeordnet, wobei zumindest einer der Bohrarme 16 und 17 jeweils unterhalb ihres zugehörigen Heb- und Senkzylinders 18, 19 angeordnet ist. Der mittlere Bohrarm ist auch teleskopierbar ausgebildet, und es ist weiters der Lafettenhalter 20 an einer Welle 21 gelagert, welche normal zur Bohrauslegerlängsrichtung und parallel zum Untergrund angeordnet ist. Der Lafettenhalter trägt eine Bohrlafette 22. Hinter den Verschiebebahnen 5, 6 und 7 ist eine Arbeitsbühne 23 angeordnet.The carriage 1 has a hydraulic supply 2 and is carried by wheels 3 on the sole. Instead of wheels, caterpillars, portals, rails, etc. can also be provided. Raisable and lowerable supports 4 are provided at the respective ends of the carriage. As can be seen in particular from FIG. 2, the carriage is articulated. At the front end seen in the direction of advance according to arrow a, three displacement tracks 5, 6 and 7 are provided. As can be seen in particular from FIG. 1, these displacement tracks are arranged essentially parallel to the sole. A console 8 with a drilling arm 9 is arranged on the sliding track 6, which extends further on site than the sliding tracks 5 and 7. This bracket 8 can be moved along the displacement path 6 in and against the direction of advance. The rotatable brackets 10 and 11 are longitudinally displaceable along the displacement tracks 5 and 7. As can be seen in particular from FIG. 2, the console 8 of the middle sliding track can be displaced further on site than the consoles 10 and 11. Each drilling arm is telescopic and has a feed device (not shown) and a percussion drilling or rotating motor with which the respective Boring bars 12, 13 and 14 are driven into the rock. On the bracket 8, the drilling arm 9 is arranged above the associated lifting and lowering cylinder 15, at least one of the drilling arms 16 and 17 being arranged below its associated lifting and lowering cylinder 18, 19. The middle drilling arm is also designed to be telescopic, and furthermore the mount 20 is mounted on a shaft 21 which is arranged normal to the longitudinal direction of the drill boom and parallel to the ground. The carriage holder carries one Drill mount 22. A work platform 23 is arranged behind the sliding tracks 5, 6 and 7.

Wie aus Fig. 1 besonders deutlich ersichtlich, können die Bohrstangen 12 und 14, welche zur Ausführung von Sprenglöchern dienen, in die Brust hineingetrieben werden, unabhängig von der Ankerarbeit, die beispielsweise mit der Bohrstange 13 durchgeführt wird. In Fig. 1 sind drei Bohrlöcher 24, 25 und 26 schematisch dargestellt, welche in den First getrieben wurden, die einen Abstand voneinander aufweisen, und zwar bezogen auf die Vortriebsrichtung a. Wie deutlich ersichtlich, kann in einer Arbeitsstellung des Wagens unabhängig von der Ausführung der Sprenglöcher der Bohrarm für die Ausführungs der Ankerlöcher in und entgegen der Vortriebsrichtung verfahren werden, sodaß keine gegenseite Behinderung gegeben ist,und Ankerlöcher und Vortriebslöcher gleichzeitig ausgeführt werden können. Von der Anzahl der erforderlichen Bohr- bzw. Sprenglöcher ist es auch abhängig, in welcher Anzahl die einzelnen Bohraggregate vorgesehen sind.As can be seen particularly clearly from FIG. 1, the boring bars 12 and 14, which are used to carry out blast holes, can be driven into the chest, regardless of the anchoring work which is carried out, for example, with the boring bar 13. In Fig. 1, three boreholes 24, 25 and 26 are shown schematically, which were driven into the ridge, which are spaced from one another, with respect to the direction of advance a. As can clearly be seen, irrespective of the execution of the blast holes, the drilling arm for executing the anchor holes can be moved in and against the direction of advance in a working position of the carriage, so that there is no mutual obstruction, and anchor holes and advance holes can be carried out simultaneously. The number of the individual drilling units is also dependent on the number of drilling or blasting holes required.

Das Absenken der heb- und senkbaren Abstützungen wird immer dann erfoderlich sein, wenn an einer Stelle mehrere Bohrarbeiten durchgeführt werden, um jegliches Verreiben der Bohrstangen und dgl. durch Positionsänderungen des Wagens im Gestein zu vermeiden. Die Lafette 22 für die Ausführung der Ankerlöcher kann kürzer oder teleskopierbar,. z.B. zur Ankerführung von Sprenglöchern in Vortriebsrichtung ausgebildet sein, als die Lafette für die Durchführung'der Sprenglöcher, da in der Regel die Stollenhöhe geringer ist, als die Länge der Sprenglöcher.The lowering of the raisable and lowerable supports will always be necessary if several drilling operations are carried out in one place in order to avoid any rubbing of the drill rods and the like due to changes in the position of the carriage in the rock. The carriage 22 for the execution of the anchor holes can be shorter or telescopic. e.g. be designed for the anchorage of blast holes in the direction of propulsion, as the carriage for the execution of the blast holes, since as a rule the stud height is less than the length of the blast holes.
