Description
Vortriebs- oder Gewinnuncrsmaschine für den Abbau von Gestein Driving or mining machine for quarrying rock
Die Erfindung bezieht sich auf eine Vortriebs- oder Gewinnungsmaschine für den Abbau von Gestein mit nach dem Hinterschneideprinzip arbeitenden Disken- bzw. Rollenwerkzeugen, welche an einem schwenkbaren Auslegerarm der Maschine rotierbar gelagert sind, mit einem die Werkzeuge tragenden Kopf, dessen Rotationsachse im wesentlichen in Richtung der Achse des Auslegerarmes verläuft .The invention relates to a tunneling or extraction machine for the extraction of rock with disc or roller tools working according to the undercut principle, which are rotatably mounted on a pivotable cantilever arm of the machine, with a head carrying the tools, the axis of rotation of which essentially in the direction the axis of the cantilever arm.
Aus der DE 39 05 737 AI ist bereits ein Verfahren zum Bohren von Stollen, Tunneln, Kavernen od.dgl. und insbesondere von Bogen- profilen bekanntgeworden, bei welchem eine Maschine zum Einsatz gelangt, deren Bohrköpfe an einem in alle Richtungen gelenkig und bewegbar angeordneten Arm festgelegt sind und Hinterschneidwerkzeuge aufweisen. Derartige Hinterschneidwerkzeuge erlauben insbesondere bei hartem Gestein die Schneidleistung durch einen wesentlich höheren Anteil an gebrochenem Material zu erhöhen, wobei mit derartigen nach dem Hinterschneideprinzip arbeitenden Werkzeugen aufgrund der grobstückigen abgetragenen Teile nicht nur schneller und rationeller, sondern auch mit wesentlich geringerer Staubentwicklung ein Vortrieb bzw. ein Abbau gelingt. Insbesondere bei Gesteinen höherer Härte und höherem Quarzgehalt ist ein derartiges Brechen unter Anwendung von nach dem Hinter- Schneideprinzip arbeitenden Werkzeugen in aller Regel wirtschaftlicher als ein konventionelles Schrämen, bei welchem das Material lediglich geschnitten wird. Hinterschneidend abtragende Rollen- oder Fräsbohrwerkzeuge, bei welchen von der Mitte eines Stollens, Tunnels oder Schachtes aus ohne Vorbohrloch von innen nach außen schichtweise ein Abtrag vorgenommen wird, sind auch in der DE 41 42 800 AI beschrieben. Bei dieser Einrichtung wird von innen nach außen hinterschneidend radial Schicht für Schicht abgetragen, wobei die Werkzeuge an einem rotierend angetriebenen Bohrkopf befestigt sind. Für das Auffahren niedriger Flöze wurden bereits niedrig bauende Einrichtungen bekannt, welche mit Fräsköpfen ausgestattet und in der Regel über einen eigenen Antrieb verfügen. Mit derartig bekannten Einrichtungen, welche auch als "Narrow Reef Miner" bezeichnet werden, wurde aber in der Regel das Material geschnitten.From DE 39 05 737 AI a method for drilling tunnels, tunnels, caverns or the like is already. and has become known, in particular, from curved profiles, in which a machine is used, the drill heads of which are attached to an arm which is articulated and movable in all directions and have undercutting tools. Such undercutting tools allow the cutting performance to be increased, in particular in the case of hard rock, by means of a substantially higher proportion of broken material, with such tools working according to the undercutting principle, not only faster and more efficiently, but also with significantly less dust, due to the large-scale removed parts Dismantling succeeds. In particular with rocks of higher hardness and higher quartz content, such breaking using tools that work according to the undercutting principle is generally more economical than conventional cutting, in which the material is only cut. Undercut cutting roller or milling drilling tools, in which removal is carried out in layers from the center of a tunnel, tunnel or shaft without a pre-drilled hole from the inside to the outside, are also described in DE 41 42 800 AI. With this device, radial undercuts are removed from inside to outside, layer by layer, the tools being attached to a rotatingly driven drill head. Low-profile devices, which are equipped with milling heads and generally have their own drive, have already been known for driving low seams. With such known devices, which also known as "narrow reef miners", but the material was usually cut.
Die Erfindung zielt nun darauf ab, eine kompakt und niedrig bauende Einrichtung zu schaffen, mit welcher niedrige Flöze unter Verwendung des Hinterschneidprinzipes effizient und wirtschaftlich abgebaut werden können und mit welcher es möglich ist hartes Material im Flözstreckenverlauf auch ferngesteuert abzubauen. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Vortriebs- oder Gewinnungsmaschine im wesentlichen darin, daß die am Auslegerarm festgelegte Rotationsachse des die Werkzeuge tragenden Kopfes am Maschinenrahmen um eine die Achse des Auslegerarmes kreuzende Achse schwenkbar gelagert ist und in Vortriebsrichtung vor der Schwenkachse des Auslegerarmes verläuft. Dadurch, daß die am Auslegerarm festgelegte Rotationsachse des die Werkzeuge tragenden Kopfes am Maschinenrahmen um eine die Achse des Auslegerarmes kreuzende Achse schwenkbar gelagert ist, wird eine Ausbildung geschaffen, bei welcher die Ortsbrust im wesentlichen entlang eines Kreisbogens abgebaut werden kann, wobei die einzelnen Disken- bzw. Rollenwerkzeuge in jeweils optimaler Position zum Einsatz gelangen können. Dadurch, daß die Rotationsachse des die Werkzeuge tragenden Kopfes in Vortriebsrichtung vor der Schwenkachse des Auslegerarmes verläuft, gelingt es die Disken- bzw. Rollenwerkzeuge so anzustellen, daß ein entsprechender Freischneidwinkel über die gesamte Abbaufront gewährleistet ist und bei einer Verschwenkung des Auslegerarmes jeweils eine besonders wirtschaftliche Brecharbeit geleistet werden kann. Durch die Verlagerung der Rotationsachse des die Werkzeuge tragenden Kopfes in Richtung zur Ortsbrust gelangt jeweils das erste Schneidwerkzeug einer Mehrzahl von in einer Ebene angeordneten Schneidwerkzeugen unter Einhalten des gewünschten Freischneidwinkels zum Einsatz, wobei die nachfolgenden Werkzeuge jeweils in die Spur dieses Werkzeuges eintreten. Im Gegensatz zu bekannten Einrichtungen kann ein optimaler Freischneidwinkel erzielt werden, da die hintereinander zum Einsatz gelangenden Werkzeuge nicht in der Tangentialebene der Schwenkbewegung zum Einsatz gelangen und daher auch für nach- folgende Werkzeuge ein entsprechender Freischneidwinkel immer gewährleistet ist. Mit Vorteil ist die Ausbildung hier so getroffen, daß die Schwenkachse des Auslegerarmes normal zur Vortriebsrichtung angeordnet ist, wobei eine derartige Ausbil- düng die Möglichkeit bietet die Maschine insgesamt überaus niedrig und kompakt auszubilden. Zu diesem Zweck ist mit Vorteil die Ausbildung so getroffen, daß der Durchmesser des Hüllkreises der Schneidwerkzeuge größer oder gleich der Maschinenhöhe ist, wobei vorzugsweise der Schwenkwinkel der Achse des Auslegerarmes aus- gehend von einer quer zur Vortriebsrichtung verlaufenden Richtung der Achse des Auslegerarmes kleiner als 150° , vorzugsweise etwa 120°, beträgt. Mit einer derartigen Ausbildung wird bei einer einzigen vollständigen Schwenkbewegung über den vordefinierten Schwenkwinkel ein Abbau in einer Höhe bewirkt, welche ein nachträgliches Verfahren bzw. Verschieben der Maschine aufgrund der geringen Bauhöhe in einfacher Weise ermöglicht.The invention now aims to provide a compact and low-construction device with which low seams can be mined efficiently and economically using the undercutting principle and with which it is possible to mine hard material in the course of the seam also by remote control. To achieve this object, the tunneling or extraction machine according to the invention essentially consists in the fact that the axis of rotation of the head bearing the tools on the cantilever arm is pivotally mounted on the machine frame about an axis crossing the axis of the cantilever arm and extends in the direction of advance in front of the pivot axis of the cantilever arm. The fact that the axis of rotation of the head carrying the tools, which is fixed on the extension arm, is pivotally mounted on the machine frame about an axis crossing the axis of the extension arm, creates a configuration in which the working face can be broken down essentially along an arc, with the individual disc or roller tools can be used in the optimal position. Because the axis of rotation of the head carrying the tools runs in the direction of advance in front of the swivel axis of the cantilever arm, the disc or roller tools can be set up in such a way that a corresponding clearance angle is guaranteed over the entire front of the excavation and each is particularly economical when the cantilever arm is pivoted Crushing work can be done. By shifting the axis of rotation of the head carrying the tools in the direction of the working face, the first cutting tool of a plurality of cutting tools arranged in one plane is used while maintaining the desired free cutting angle, the subsequent tools each entering the track of this tool. In contrast to known devices, an optimal free cutting angle can be achieved since the tools used one behind the other are not used in the tangential plane of the swiveling movement and therefore also for subsequent following tools a corresponding clearance angle is always guaranteed. The design here is advantageously made such that the pivot axis of the cantilever arm is arranged normal to the direction of advance, such a design offering the possibility of making the machine extremely low and compact overall. For this purpose, the design is advantageously made such that the diameter of the enveloping circle of the cutting tools is greater than or equal to the machine height, the pivoting angle of the axis of the cantilever arm preferably starting from a direction of the axis of the cantilever arm that is transverse to the direction of advance less than 150 °, preferably about 120 °. With such a design, a single complete swivel movement over the predefined swivel angle causes degradation at a height which, due to the low overall height, enables subsequent movement or displacement of the machine in a simple manner.
Für die jeweils zu Beginn des Abbauvorganges erforderliche Einbruchbewegung bzw. korrekte Anstellung der Werkzeuge zu Beginn des Schneidvorganges ist mit Vorteil die Ausbildung so getroffen, daß das Schwenklager des Auslegerarmes an einem in Längsrichtung des Maschinenrahmens verschieblichen Schlitten angeordnet ist. Eine in der Strecke positionierte Maschine kann somit zunächst in der Strecke entsprechend verspannt bzw. fest- gelegt werden, worauf durch Anstellen des verschieblichen Schlittens in Richtung zur Ortsbrust ein Einbruchschnitt erzielt werden kann, von welchem ausgehend unter einem Freiwinkel von beispielsweise etwa 5° die weitere Schneidarbeit unter Optimierung des gebrochenen Anteiles vorgenommen werden kann. Mit Vor- teil ist die Ausbildung hiebei so getroffen, daß die Schneidkanten der Disken in einer gemeinsamen zur Rotationsachse des Kopfes normalen Ebene am Kopf angeordnet sind, welche mit der Tangente an den Hüllkreis der Schwenkbewegung des Armes einen Winkel zwischen 2° und 10°, vorzugsweise etwa 5°, einschließt. Eine derartige Ausbildung erlaubt ein besonders rasches und wirtschaftliches Brechen von hartem Gestein, wobei im Rahmen einer derartigen Ausbildung wenigstens 3, vorzugsweise wenigstens 4, Disken an der Stirnfläche des Kopfes angeordnet sind.For the break-in movement required at the start of the dismantling process or the correct placement of the tools at the start of the cutting process, the design is advantageously made such that the pivot bearing of the cantilever arm is arranged on a slide which is displaceable in the longitudinal direction of the machine frame. A machine positioned in the route can thus first be appropriately braced or fixed in the route, whereupon a burglary cut can be achieved by moving the sliding carriage in the direction of the working face, from which the further one starts at a clearance angle of, for example, approximately 5 ° Cutting work can be done while optimizing the broken portion. Advantageously, the design is such that the cutting edges of the disks are arranged on the head in a plane normal to the axis of rotation of the head, which is at an angle between 2 ° and 10 ° with the tangent to the enveloping circle of the swiveling movement of the arm. preferably about 5 °. Such training allows a particularly quick and economical breaking of hard rock, in the frame such a configuration at least 3, preferably at least 4, disks are arranged on the end face of the head.
Um in der Folge die Möglichkeit zu bieten den zuvor definierten Freischneidewinkel den jeweiligen Bedürfnissen und insbesondere der jeweiligen Gesteinsbeschaffenheit optimal anpassen zu können, ist mit Vorteil die Ausbildung so getroffen, daß der Auslegerarm relativ zur Schwenkachse des Schwenklagers normal zur Schwenkachse verlagerbar am Schwenklager festgelegt ist. Die relative Verschiebung der Achse des Auslegerarmes relativ zur dieser Achse kreuzenden Schwenkachse des Schwenklagers führt hiebei über den definierten Schwenkwinkel zu einer Verstellung des Freischneidewinkels, welcher auf diese Weise justierbar ist.In order to be able to subsequently optimally adapt the previously defined clearing angle to the respective needs and in particular to the particular type of rock, the design is advantageously made such that the cantilever arm is fixed to the swivel bearing in a manner that can be displaced relative to the swivel axis of the swivel bearing normally to the swivel axis. The relative displacement of the axis of the cantilever arm relative to the pivot axis of the pivot bearing crossing this axis leads to an adjustment of the clearing angle, which can be adjusted in this way, via the defined pivot angle.
Um eine sichere Verankerung der Maschine im Flözstreckenverlauf zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß der Maschinenrahmen mit Spreizen oder Stempeln im Vortriebs- bzw. Abbaustollen oder Flöz verspannbar ist. Eine besonders einfache Manövrierbarkeit der gesamten Einrichtung läßt sich dadurch erzielen, daß am dem Schwenklager abgewandten Hinterende des Schlittens ein quer zur Maschinenlängsrichtung verschieblich gelagerter und im wesentlichen parallel zur Schwenkachse ausfahrbarer Stempel zur Abstützung zur Sohle bzw. zur Verspannung im Flöz angeordnet ist. In diesen Fällen ist es lediglich erforderlich die Spreizen oder Stempel, mit welchen die Maschine im Abbaustollen insbesondere zwischen Sohle und Firste verspannbar ist, zu lösen, worauf in der Folge mit dem dem Schwenklager abgewandten Stempel aufgrund der seitlichen Verschieblichkeit dieses Stempels eine entsprechende Positionie- rung der Maschine relativ zu diesem Stempel ermöglicht wird.In order to ensure that the machine is securely anchored in the course of the seam, the design is advantageously made such that the machine frame can be braced with spreaders or punches in the tunnel or excavation tunnel or seam. A particularly simple maneuverability of the entire device can be achieved in that on the rear end of the slide facing away from the swivel bearing there is arranged a plunger which is displaceable transversely to the longitudinal direction of the machine and can be extended essentially parallel to the swivel axis for support to the sole or for tensioning in the seam. In these cases, it is only necessary to loosen the spreaders or punches with which the machine can be clamped in the excavation tunnel, in particular between the base and the roof, whereupon a corresponding positioning with the plunger facing away from the pivot bearing due to the lateral displaceability of this plunger the machine is enabled relative to this stamp.
Um eine sichere Abförderung des gewonnenen Materiales zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß am dem Schwenkwerk benachbarten Ende der Maschine eine Ladeschurre angeordnet ist, wobei ein sicheres und vollständiges Räumen einer derartigen Ladeschurre in besonders einfacher Weise dadurch gelingt, daß mit dem schwenkbaren Auslegerarm mit der Ladeschurre zusammenwirkende Räumschaufeln verbunden sind. Die mit der Ladeschurre zusammenwirkenden Räumschaufeln können hier schwenkbar oder ausfahrbar ausgebildet sein, sodaß sie lediglich in einer der beiden Schwenkrichtungen des Auslegerarmes mit der Ladeschurre zusammenwirken.In order to ensure safe removal of the material obtained, the design is advantageously made such that a loading chute is arranged at the end of the machine adjacent to the swivel mechanism, a safe and complete clearing of such a loading chute being achieved in a particularly simple manner in that with the swiveling boom with the Loading chute interacting clearing blades are connected. The clearing blades interacting with the loading chute can be designed to be pivotable or extendable, so that they only interact with the loading chute in one of the two pivoting directions of the extension arm.
Aufgrund des mit etwa 120° beschränkten Schwenkwinkels kann die Maschine asymmetrisch in der Strecke angeordnet werden, sodaß an derjenigen Seite, an welcher der Einbruchschneidvorgang beginnt , ein entsprechender Freiraum für das Nachführen von Abförderein- richtungen geschaffen wird . Da beim Einschnitt die Schneidtrommel mit einem Freiwinkel von etwa 5 ° zur seitlichen Ortsbrust angestellt zum Einsatz gelangt und über die Vorschubeinrichtung ein Einbruch durchgeführt wird, worauf anschließend der Auslegerarm um etwa 120° verschwenkt wird, gelangen die in einer Ebene liegenden hintereinander zum Einsatz gelangenden Disken immer in die selbe Spur, wodurch ein weiterer Materialeinschnitt vorgenommen wird, sodaß Material mit einem hohen Brechanteil herausgebrochen wird. Bei einem einzigen Schwenkvorgang kann das Material über den gesamten abzubauenden Querschnitt herausgelöst werden, sodaß der entsprechende Freiraum für die Verschiebung des Maschinenrahmens geschaffen wird, wobei eine durch die Länge des zulässigen Verschiebeweges des Schlittens vorgegebene Strecke ohne Verschiebung des Maschinenrahmens abgebaut werden kann, wofür lediglich der Schlitten entsprechend zu verschieben ist . Das Schwenkwerk, mit welchem der Auslegerarm um eine quer zur Vortriebsrichtung liegende Achse verschwenkbar ist , kann in einfacher Weise über Hydraulikzylinder angetrieben werden, welche am Maschinenrahmen abgestützt sind, sodaß auch hier mit niedrigbauenden Einrichtungen das Auslangen gefunden werden kann .Due to the limited swivel angle of approximately 120 °, the machine can be arranged asymmetrically in the path, so that on the side on which the burglary cutting process begins, a corresponding space is created for the tracking of discharge devices. Since the cutting drum is used with a clearance angle of about 5 ° to the lateral face when cutting, and a break-in is carried out via the feed device, whereupon the cantilever arm is subsequently pivoted by approximately 120 °, the disks lying one behind the other are used Always in the same track, which means that a further material cut is made so that material with a high proportion of crushing is broken out. In a single swiveling process, the material can be removed over the entire cross-section to be dismantled, so that the corresponding space is created for the displacement of the machine frame, a distance predetermined by the length of the permissible displacement path of the slide being able to be reduced without displacement of the machine frame, for which only the Slide is to be moved accordingly. The swivel mechanism, with which the cantilever arm can be pivoted about an axis lying transversely to the direction of advance, can be driven in a simple manner by means of hydraulic cylinders which are supported on the machine frame, so that it can also be found here with low-profile devices.

In Fig. 1 ist ein Maschinenrahmen 1 dargestellt, an welchem ein Schlitten 2 in Richtung des Doppelpfeiles 3 längsverschieblich gelagert ist. Am Schlitten 2 ist am Hinterende ein Widerlagerbock angeordnet, an welchem Schwenkzylinder 4 und 5 für eine Verschwenkung eines Schwenkwerkes 6 um eine die Vortriebsrich- tung 10 kreuzende Schwenkachse 7 abgestützt sind. Am Schwenklager 6 ist ein Auslegerarm 8 festgelegt, dessen Achse 20 ebenso wie die Bohrkopfachse 9 des Schneidkopfes 13 in Vortriebsrichtung 10 vor der Schwenkachse 7 des Schwenkwerkes 6 liegt. Der Ausleger kann jedoch auch gekröpft bzw. geknickt ausgebildet sein. Durch die Ausrichtung der Bohrkopfachse wird sichergestellt, daß beim Verschwenken des Schwenkwerkes 6 in Richtung des Doppelpfeiles 11 über den gesamten Schwenkwinkel von etwa 120° ein entsprechender Freischneidwinkel α der Schneiddisken 12 eines Schneidkopfes 13 gewährleistet ist. Am vorderen Ende des Maschinenrahmens 1, welches der Ortsbrust 14 benachbart ist, ist eine Ladeschurre 15 ersichtlich, über welches Material in Richtung des Pfeiles 16 auf eine nicht dargestellte Abfördereinrich- tung geschoben werden kann.In Fig. 1, a machine frame 1 is shown, on which a carriage 2 is mounted for longitudinal displacement in the direction of the double arrow 3. An abutment bracket is arranged on the carriage 2 at the rear end, on which pivot cylinders 4 and 5 are supported for pivoting a pivoting mechanism 6 about a pivot axis 7 crossing the direction of advance 10.

However, the boom can also be cranked or kinked. The alignment of the drill head axis ensures that when the swivel mechanism 6 is pivoted in the direction of the double arrow 11 over the entire swivel angle of approximately 120 °, a corresponding free cutting angle α of the cutting disks 12 of a cutting head 13 is ensured. At the front end of the machine frame 1, which is adjacent to the working face 14, a loading chute 15 can be seen, via which material can be pushed in the direction of arrow 16 onto a discharge device, not shown.

Am Widerlagerbock des Schlittens schließlich ist ein weiterer Stützstempel 18 angeordnet, welcher über ein hydraulisches Zylinder olbenaggregat 19 in einer entsprechenden Führung seitlich verschoben werden kann, sodaß bei ausgefahrenem Stempel 18 der Schlitten und damit der Maschinenrahmen 1 seitlich verschoben werden kann, sofern die Stützstempel 17 eingefahren sind.Lateral support claws 17 are arranged on the machine frame or on the slide, with which the machine can be clamped between the roof and the sole. Finally, on the abutment block of the slide, a further support ram 18 is arranged, which can be moved laterally in a corresponding guide via a hydraulic cylinder olbenaggregat 19, so that when the ram 18 is extended, the slide and thus the machine frame 1 can be moved laterally, provided the support rams 17 are retracted are.
