Description

Die Erfindung bezieht sich auf eine Streckenvortriebsmaschine mit einem fahrbaren Wagen mit Druckmediumversorgung und einer Verschiebebahn für einen Bohrausleger mit Bohrlafette sowie einem Bohr-, insbesondere Schlagbohrmotor und Vorschubmotor, einem drehbar um die vertikale Achse auf einem am Wagen angeordneten Anlenkstück, insbesondere für einen Ausleger, z.B. Schrämausleger, welcher auf- und abbewegbar am Anlenkstück gelagert ist.The invention relates to a tunnel boring machine with a mobile carriage with pressure medium supply and a sliding track for a drilling jib with drilling mount and a drilling, in particular percussion drilling motor and feed motor, a pivotable about the vertical axis on a pivot piece arranged on the carriage, in particular for a boom, e.g. Cutter boom, which is mounted on the link piece so that it can be moved up and down.

Streckenvortriebsmaschinen, beispielsweise für den Abbau von Gestein, Kohle od.dgl. oder auch zum Bau von Tunneln, Stollen usw., weisen zumindest ein Abbauaggregat, beispielsweise eine Vollschnitt- bzw. Teilschnittfräse auf, welcher Fräskopf auf einem am Wagen heb- und senkbar sowie über ein Anlenkstück drehbar am Wagen gelagerten Schrämausleger gelagert ist. Zusätzlich zu einem derartigen Abbauorgan kann auf einem Vortriebswagen ein Bohrarm samt Bohrlafette angeordnet sein. Dieser Bohrarm kann nun sowohl zum Abbau verwendet werden, wobei dann die Bohrlöcher im wesentlichen in Vortriebsrichtung angeordnet werden, und gegebenenfalls zur Aufnahme von Sprengladungen dienen, oder es können auch Bohrlöcher quer zur Vortriebsrichtung, beispielsweise im First oder auch in den Seitenwänden vorgesehen werden, um eine Absicherung des Stollens durch beispielsweise Klebe- oder Spreizanker zu erreichen. Da unter Tage und auch bei der Anfertigung von Stollen od.dgl. in der Regel mit Vorrichtungen gearbeitet werden muß, die möglichst geringe Abmessungen aufweisen, besteht bei der gleichzeitigen Anordnung von mehr als einem Abbau- bzw. Bohraggregat die Gefahr, daß beispielsweise die Fräse durch den Bohrarm behindert wird. In der österreichischen Patentschrift 372 758 wird eine Streckenvortriebsmaschine beschrieben, die einen Fräsausleger aufweist, wobei am Auslegerarm eine quer zur Vortriebsrichtung angeordnete Querverschiebebahn vorgesehen ist. Durch diese Querverschiebebahn kann zwar der Bohrarm aus dem Arbeitsbereich des Fräsauslegers geschoben werden, jedoch kann bei bestimmten Schwenkbewegungen und auch Heb- und Senkbewegungen es erforderlich sein, den Bohrarm anders zu positionieren.Line boring machines, for example for the mining of rock, coal or the like. or for the construction of tunnels, tunnels, etc., have at least one mining unit, for example a full cut or partial cut milling cutter, which milling head is mounted on a carriage that can be raised and lowered and rotated on the carriage by means of a linkage piece mounted on the carriage. In addition to such a dismantling member, a drilling arm including a drilling mount can be arranged on a jacking car. This drill arm can now be used for dismantling, in which case the boreholes are arranged essentially in the direction of advance, and possibly serve to receive explosive charges, or boreholes can also be provided transversely to the direction of advance, for example in the ridge or in the side walls to secure the gallery with e.g. anchoring or expansion anchors. Since underground or the like when making studs or the like. usually must be worked with devices that have the smallest possible dimensions, there is a risk with the simultaneous arrangement of more than one mining or drilling unit that, for example, the cutter is hindered by the drilling arm. In the Austrian patent specification 372 758 a line boring machine is described which has a milling boom, a cross-displacement track arranged transversely to the direction of advance being provided on the boom arm. This cross slide path allows the drilling arm to be pushed out of the working area of the milling boom, but with certain pivoting movements and also lifting and lowering movements it may be necessary to position the drilling arm differently.

In der EP-A 83 334 ist eine Schrämmaschine beschrieben, die eine Konsole enthält, an welcher ein über Hydraulikzylinder heb-, senk- und schwenkbarer und teleskopierbarer Bohrausleger angelenkt ist, der einen Mannkorb sowie eine drehbare Lafette mit Bohrmaschine trägt. Der Mannkorb ist mit dem Bohrausleger über eine Parallelführung verbunden und die Konsole ist entlang einer Längsverschiebebahn verschiebbar. Die EP-A 0 137 000 und die FR-A 2 342 394 befassen sich mit einem fahrbaren Wagen, wobei der Oberwagen eine Verschiebebahn aufweist, die ein umgreifendes Lager enthält und als Geradführung dient. Auf dieser Verschiebebahn ist an der der Abbaufront zugewandten Seite die Konsole und am anderen Ende das Druckmediumaggregat montiert. In der EP-A 0 080 455 ist eine Streckenvortriebsmaschine beschrieben, die sich dadurch auszeichnet, daß die auf der Verschiebebahn angeordnete Konsole in und quer zur Vortriebsrichtung verschiebbar ist. Es ist mit diesen bekannten Vortriebsmaschinen jedoch nicht möglich, eine extrem lange Vortriebsbahn zu verwenden, die seitlich schwenkbar ist und mit ihrem rückwärtigen Ende am Wagen in Seitenstellung abstützbar und lagefixierbar ist.EP-A 83 334 describes a cutting machine which contains a bracket to which a drilling boom which can be raised, lowered and swiveled and which can be telescoped is articulated and which carries a man's basket and a rotatable carriage with a drilling machine. The man basket is connected to the drill boom via a parallel guide and the console can be moved along a longitudinal displacement path. EP-A 0 137 000 and FR-A 2 342 394 deal with a mobile carriage, the upper carriage having a sliding track which contains a comprehensive bearing and serves as a straight guide. The console is mounted on this sliding track on the side facing the dismantling front and the pressure medium unit at the other end. EP-A 0 080 455 describes a tunnel boring machine which is characterized in that the bracket arranged on the sliding track can be displaced in and transversely to the direction of advance. However, it is not possible with these known tunneling machines to use an extremely long tunneling track which can be pivoted laterally and can be supported and fixed in position with its rear end on the car in the lateral position.

Die vorliegende Erfindung hat es sich zur Aufgabe gesetzt, eine Streckenvortriebsmaschine zu schaffen, die einen Bohrarm mit Bohrlafette aufweist, welcher von einer Arbeitsstellung in eine Ruhestellung verbracht werden kann, womit eine volle freie Arbeitsfähigkeit eines gegebenenfalls weiteren Abbauaggregates gegeben ist, wobei weiters eine besonders freie Sicht zum Abbauort gegeben ist. Weiters soll die Vorrichtung zur Dislozierung der Bohreinrichtung möglichst einfach und besonders stabil ausgebildet sein, wobei auch eine besonders geringe Bauhöhe erreichbar sein soll.The present invention has set itself the task of creating a track boring machine that has a drilling arm with drill carriage, which can be moved from a working position to a rest position, which gives a full free working ability of a further mining unit, if necessary, and a particularly free one There is a view of the extraction site. Furthermore, the device for relocating the drilling device should be as simple and particularly stable as possible, and it should also be possible to achieve a particularly low overall height.

Die erfindungsgemäße Streckenvortriebsmaschine mit einem fahrbaren Wagen mit Druckmediumversorgung und einer Verschiebebahn für einen Bohrausleger mit Bohrlafette sowie einem Bohr-, insbesondere Schlagbohrmotor und Vorschubmotor, einem drehbar um die vertikale Achse auf einem am Wagen angeordneten Anlenkstück, insbesondere für einen Ausleger, z.B. Schrämausleger, welcher auf- und abbewegbar am Anlenkstück gelagert ist, ist zur Lösung dieser Aufgabe im wesentlichen dadurch gekennzeichnet, daß die in Vortriebsrichtung verfahrbare Verschiebebahn für den Bohrarm am Anlenkstück seitlich schwenkbar gelagert ist und am Wagen am rückwärtigen Ende über ein Auflager abstützend und lagefixierbar ist. Durch eine derartige Streckenvortriebsmaschine wird erreicht, daß die Bohrvorrichtung zur Anfertigung von z.B. Anker- bzw. Sprenglöcher, Vorort verschoben werden kann, wobei durch die am Anlenkstück vorgesehene Lagerung eine sehr stabile und hohe Kräfte aufnehmende Abstützung der Verschiebebahn gegeben ist. Weiters kann dadurch eine besonders geringe Bauhöhe eingehalten werden.The tunnel boring machine according to the invention with a mobile carriage with pressure medium supply and a sliding track for a drilling jib with drilling mount and a drilling, in particular percussion drilling motor and feed motor, a rotatable about the vertical axis on a coupling piece arranged on the carriage, in particular for a boom, e.g. Cutter boom, which is mounted up and down on the articulation piece, is essentially characterized in solving this task in that the sliding path for the drill arm, which is movable in the direction of advance, is pivoted laterally on the articulation piece and is supported and fixed in position on the carriage at the rear end via a support . With such a tunnel boring machine it is achieved that the drilling device for the production of e.g. Anchor or blast holes can be moved on site, whereby the support provided on the articulation piece provides a very stable and high force-supporting support of the sliding track. Furthermore, a particularly low overall height can be maintained.

Gemäß einem weiteren Merkmal der vorliegenden Erfindung ist die Verschiebebahn mittig auf dem Anlenkstück gelagert und das dem Anlenkstück abgewandte Ende am Wagen außermittig lagefixierbar. Dadurch wird erreicht, daß die Verschiebebahn zwar in Vortriebsrichtung orientiert ist, jedoch eine geringe Neigung zu derselben aufweist, womit bei einer geringen Breitenerstreckung der Vortriebsmaschine noch genügend Platz verbleibt, daß auf einer Seite der Verschiebebahn ein Bedienungsmann angeordnet werden kann, welcher durch die Bewegung der Bohrvorrichtung nicht gefährdet ist.According to a further feature of the present invention, the sliding track is mounted centrally on the articulation piece and the end facing away from the articulation piece can be fixed off-center on the carriage. It is thereby achieved that the sliding track is oriented in the direction of advance, but has a slight inclination to the same, so that with a small width of the tunneling machine there is still enough space that an operator can be arranged on one side of the sliding track, which can be arranged by the movement of the Drilling device is not at risk.

Eine besonders einfache und stabile Konstruktion ergibt sich dann, wenn auf der vorzugsweise mit T-Träger gebildeten Verschiebebahn eine diesen teilweise umgreifende Konsole längsverschieblich angeordnet ist.A particularly simple and stable construction is obtained if a console, which partially surrounds this, is arranged so as to be longitudinally displaceable on the sliding track, which is preferably formed with a T-beam.

Eine geringe Längserstreckung kann dann erreicht werden, wenn direkt an der Konsole der Bohrarm, ein Heb- und Senkzylinder und ein Schwenkzylinder angeordnet sind. Eine besonders hohe Beweglichkeit der Bohrlafette ist dann gegeben, wenn der Bohrarm eine an diesem angelenkte Bohrlafette trägt. Eine besonders geringe Längserstreckung der Streckenvortriebsmaschine bei gleichzeitig geringster Arbeitsbehinderung Vorort ist dann gegeben, wenn, wie es einer bevorzugten Ausführungsform entspricht, die Verschiebebahn eine Längserstreckung aufweist, die im wesentlichen der Summe der Längserstreckung von Konsole und festem Teil des Bohrarmes und der Längserstreckung der Bohrlafette ab Anlenkung am Bohrarm bis Vorort-Ende entspricht. Trägt gemäß einer weiteren bevorzugten Ausführungsform die auf der Verschiebebahn angeordnete Konsole die Bedienungsorgane für den Bohrarm mit Lafette, so können besonders kurze Steuerleitungen eingehalten werden, wobei gleichzeitig die geringste Beeinträchtigung bei Verschiebung der Konsole durch Hydraulik, Leitungen u.dgl. erreichbar sind. Ist die Verschiebebahn mit einem Ende am Anlenkstück abstützend gelagert, so kann die Hebbewegung des Auslegers, gegebenenfalls Schrämauslegers, um einen besonders großen Winkei durchgeführt werden.A slight longitudinal extension can be achieved if the drilling arm, a lifting and lowering cylinder and a swivel cylinder are arranged directly on the console. A particularly high loading Mobility of the drill carriage is given when the drill arm carries a drill carriage articulated to it. A particularly small longitudinal extension of the tunnel boring machine with the least possible on-site work disability is given if, as it corresponds to a preferred embodiment, the sliding track has a longitudinal extension which is essentially the sum of the longitudinal extension of the console and the fixed part of the drilling arm and the longitudinal extension of the drilling mount The linkage on the drill arm corresponds to the end of the site If, according to a further preferred embodiment, the console arranged on the sliding track carries the operating elements for the drilling arm with mount, particularly short control lines can be observed, with the least impairment when the console is displaced by hydraulics, lines and the like. are reachable. If the sliding track is supported with one end on the articulation piece, the lifting movement of the jib, possibly a cantilever jib, can be carried out by a particularly large angle.

Ist die Verschiebebahn, entgegen der Vortriebsrichtung gesehen, über das Auflager am Wagen erstreckt, so kann ebenfalls eine besonders geringe Baulänge der Streckenvortriebsmaschine erreicht werden, wobei der Gewichtsverteilung auch bei in Ruhestellung verfahrener Konsole vollauf Rechnung getragen werden kann.If the sliding track, viewed against the direction of advance, extends over the support on the carriage, then a particularly small overall length of the tunnel boring machine can also be achieved, the weight distribution being able to be fully taken into account even when the console is moved into the rest 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 eine Streckenvortriebsmaschine in Seitensicht und Fig. 2 die Streckenvortriebsmaschine gemäß Fig. 1 in Draufsicht.1 shows a tunnel boring machine in a side view and FIG. 2 shows the tunnel boring machine according to FIG. 1 in plan view.

Die in Fig. 1 dargestellte Streckenvortriebsmaschine weist einen fahrbaren Wagen 1 mit Raupen 2 auf. Über diese Raupen kann sich die Streckenvortriebsmaschine am Untergrund 30 in und entgegen der Vortriebsrichtung a bewegen. Durch ungleiches Bewegen der Raupen kann auch eine Schwenkbewegung der Streckenvortriebsmaschine erreicht werden. Am Wagen ist ein Anlenkstück 3 um die Achse b schwenkbar angeordnet. Die Achse b ist im wesentlichen normal zum Untergrund 30 vorgesehen. Das Anlenkstück kann über einen nicht dargestellten Zahnkranz mit Ritzel mit einem Hydraulikmotor gedreht werden. Am Anlenkstück 3 ist ein Schrämausleger 4 heb- und senkbar angelenkt. Dieser Schrämausleger 4 trägt einen Fräskopf 5 an seinem Ende, der mit etwa teilkugelförmigen Fräsköpfen 5a, 5b , auf welchen nicht dargestellte Meißel, beispielsweise Rundschaftmeißel, angeordnet sind, aufgebaut ist. Durch eine Schwenkbewegung des Anlenkstückes 3 wird,insbesondere wie aus Fig. 2 ersichtlich, eine Schwenkbewegung des Schrämauslegers 4 durchgeführt. Am Anlenkstück 3 ist das eine Ende einer Verschiebebahn 6, und zwar über ein Gleitlager (nicht dargestellt), gelagert. Anstelle des Gleitlagers kann auch beispielsweise ein Nadellager od. dgl. vorgesehen sein, das geeignet ist, entsprechende Axialdrücke aufzunehmen. Die Verschiebebahn ist weiters auf einem Auflager 7 am Wagen lagefixiert, beispielsweise verschraubt, angeordnet. Die Verschiebebahn ist mit, . wie aus Fig. 1 deutlich ersichtlich, T-förmigen Trägem aufgebaut, wobei die Konsole 8 mit Fortsätzen 9 die T-Profile teilweise umfaßt. An der Konsole sind der Bohrarm 10, welcher teleskopierbar ist, und ein Heb- und Senkzylinder 11, sowie ein Schwenkzylinder 12 angelenkt. Am distalen Ende des Bohrarmes ist der Lafettenhalter und damit die Lafette 13 angelenkt. Die Anlenkung 14 des Lafettenhalters ist ihrerseits um die Längsachse des Bohrarmes 10 drehbar, sodaß die Bohrlafette um den Bohrarm zumindest teilweise drehbar ist, womit die Bohrlafette unmittelbar parallel zum Untergrund 30 oder zum First 15 anordenbar ist. Die Konsole 8 trägt, wie insbesondere aus Fig. 2 ersichtlich, die Bedienungsorgane 16 für die Bohrlafette und den Bohrarm. Die Verschiebebahn ist weiters zwar in Vortriebsrichtung a orientiert, jedoch leicht zu derselben geneigt, da die Verschiebebahn am Anlenkstück 3 mittig gelagert, jedoch das andere Ende 17 der Verschiebebahn außermittig, bezogen auf den Wagen, angeordnet ist. Dadurch wird erreicht, daß ein Bedienungsmann am Steuerpult 18 am Wagen vorgesehen sein kann, ohne durch die Verschiebebahn behindert zu werden.1 has a mobile carriage 1 with caterpillars 2. The track-boring machine can move on the subsurface 30 in and against the direction of advance a via these caterpillars. By moving the tracks unevenly, a pivoting movement of the tunnel boring machine can also be achieved. An articulation piece 3 is arranged on the carriage so as to be pivotable about the axis b. The axis b is provided essentially normal to the base 30. The articulation piece can be rotated with a hydraulic motor via a toothed ring (not shown) with a pinion. A cantilever arm 4 is articulated on the articulation piece 3 so that it can be raised and lowered. This cantilever boom 4 carries a milling head 5 at its end, which is constructed with approximately part-spherical milling heads 5a, 5b, on which chisels, not shown, for example round shank chisels, are arranged. Through a pivoting movement of the articulation piece 3, in particular, as can be seen from FIG. 2, a pivoting movement of the cantilever arm 4 is carried out. On the articulation piece 3, one end of a sliding track 6 is mounted, specifically via a slide bearing (not shown). Instead of the plain bearing, a needle bearing or the like can also be provided, for example, which is suitable for absorbing corresponding axial pressures. The sliding track is also fixed in position on a support 7 on the carriage, for example screwed. The sliding track is with,. As clearly shown in Fig. 1, T-shaped supports constructed, the console 8 with extensions 9 partially includes the T-profiles. The drilling arm 10, which is telescopic, and a lifting and lowering cylinder 11 and a swivel cylinder 12 are articulated on the console. At the distal end of the drill arm, the carriage holder and thus the carriage 13 are articulated. The articulation 14 of the mount holder is in turn rotatable about the longitudinal axis of the drill arm 10, so that the drill mount is at least partially rotatable about the drill arm, with which the drill mount can be arranged directly parallel to the base 30 or to the ridge 15. As can be seen in particular from FIG. 2, the console 8 carries the operating elements 16 for the drilling mount and the drilling arm. The sliding track is also oriented in the direction of propulsion a, but is slightly inclined to the same, since the sliding track is mounted centrally on the articulation piece 3, but the other end 17 of the sliding track is arranged off-center, relative to the carriage. It is thereby achieved that an operator can be provided on the control panel 18 on the carriage without being hindered by the sliding track.

In Fig. 1 ist strichpunktiert die Konsole samt Bohrarm und Bohrlafette in Ruheposition dargestellt, wobei eindeutig zu entnehmen ist, daß die Längserstreckung der Verschiebebahn die Summe der Längserstreckung der Konsole samt nicht teleskopiertem Bohrarm sowie Längserstreckung der Bohrlafette ab Anlenkung am Bohrarm bis Vorort-Ende beträgt. Damit ragt die Bohrlafette in Ruheposition nicht über das Anlenkstück bzw. über die Verschiebebahn hinaus.In Fig. 1 the dashed line including the drill arm and drill carriage is shown in the rest position, whereby it can clearly be seen that the longitudinal extension of the sliding track is the sum of the longitudinal extension of the console including the non-telescopic drill arm and the longitudinal extension of the drill carriage from the linkage on the drill arm to the end of the site . In the rest position, the drill carriage does not protrude beyond the articulation piece or the sliding track.

Wie aus der Zeichnung deutlich zu entnehmen, kann sowohl der Schrämausleger bei Bohrlafette in Ruheposition als auch bei abgesenktem oder hochgefahrenem Schrämausleger die Bohrmaschine ohne Behinderung durch das andere Aggregat betätigt werden. Anstelle der Fräsköpfe können auch andere gesteinsabtragende Werkzeuge vorgesehen sein.As can be clearly seen from the drawing, both the cantilever boom with the drill carriage in the rest position and with the cantilever boom lowered or raised, the drill can be operated without hindrance by the other unit. Instead of the milling heads, other stone-removing tools can also be provided.
