Description

Die Erfindung bezieht sich auf eine Schrämmaschine mit an einem schwenkbaren Schrämarm rotierbar gelagerten Schrämköpfen oder -walzen mit einer Laderampe bzw. einem in Richtung zur Ortsbrust verlaufenden Förderer für die Aufnahme und die Abförderung des geschrämten Materials, bei welcher der Schrämarm an einem auf in Maschinenlängsrichtung verlaufenden Führungen verschieblichen Schlitten gelagert ist.The invention relates to a cutting machine with rotatably mounted on a pivotable cutting arm cutting heads or rollers with a loading ramp or extending in the direction of the working face conveyor for receiving and removal of the abgeschrämten material in which the cutting arm on a running in the machine direction Guides slidable slide is stored.

Schrämmaschinen bzw. Vortriebsmaschinen, bei welchen die Abbauwerkzeuge relativ zum Maschinenrahmen auf einem Schlitten verfahrbar sind, sind beispielsweise der AT 393295 B zu entnehmen. Bei dieser bekannten Vortriebsmaschine sind am Rahmen der Vortriebsmaschine innerhalb der Raupenfahrwerke Führungsstangen vorgesehen, auf welchen ein Schlitten verfahren wird. Der Schlitten weist zu diesem Zweck rohrförmige Führungen auf, wobei die entsprechende Verfahrbarkeit längs der Führungsstangen dadurch gewährleistet ist, dass die axiale Länge der Rohrführungen kürzer ist als die axiale Länge der Führungsstangen. Bei diesen bekannten Einrichtungen sind Abförderer in einer Kulisse gelenkig mit diesem Schlitten verfahrbar.Schrämmaschinen or tunneling machines, in which the mining tools are movable relative to the machine frame on a carriage are, for example, the AT 393295 B refer to. In this known tunneling machine guide rods are provided on the frame of the tunneling machine within the crawler tracks on which a carriage is moved. The carriage has for this purpose tubular guides, wherein the corresponding mobility along the guide rods is ensured by the fact that the axial length of the pipe guides is shorter than the axial length of the guide rods. In these known devices discharge conveyor are articulated in a backdrop with this carriage.

Aus der AT 407422 B ist ein abgewandelter Schlitten mit Längsholmen bekannt geworden, welcher einen portalartigen Querträger aufweist. Dieser Schlitten umgreift wiederum mit Rohrstücken bzw. rohrförmigen Führungen die innerhalb des Raupenfahrwerksrahmens angeordneten Führungsstangen.From the AT 407422 B is a modified slide with longitudinal beams known, which has a portal-like cross member. This carriage in turn surrounds with tubular pieces or tubular guides arranged within the crawler frame guide rods.

Bei besonders niedrigbauenden Maschinen gestaltet sich die Erzielung der erforderlichen Steifigkeit und Robustheit aufgrund der verringerten Baumaße schwierig. Es wurde daher bereits vorgeschlagen, Rahmenbauteile als Kastenprofil auszubilden. So ist beispielsweise der AT 404863 B und der AT 404282 B ein Schlitten zu entnehmen, welcher als selbsttragendes Kastenprofil ausgebildet ist und an von Stangen gebildeten Längsführungen verschieblich am Rahmen gelagert ist. Die stangenförmigen Längsführungen sind wieder mit dem Rahmen des Raupenfahrwerks verbunden, wobei bei dieser Ausbildung der Förderer durch den lichten Querschnitt des als selbsttragendes Kastenprofil ausgebildeten Schlittens hindurchgeführt werden muss.In particularly low-profile machines, achieving the required rigidity and robustness is difficult due to the reduced dimensions. It has therefore already been proposed to form frame members as a box profile. For example, the AT 404863 B and the AT 404282 B to take a slide, which is designed as a self-supporting box profile and on of rods formed longitudinal guides is slidably mounted on the frame. The rod-shaped longitudinal guides are again connected to the frame of the crawler track, wherein in this embodiment, the conveyor must be passed through the clear cross-section of the designed as a self-supporting box section slide.

Die Erfindung zielt nun darauf ab, eine Vortriebsmaschine mit einer Rahmenschlittenkonstruktion für niedrige Flöze zu schaffen, welche für besonders niedrige Flöze geeignet ist und eine verbesserte Kuppen-Muldengängigkeit aufweist. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung der Vortriebsmaschine der eingangs genannten Art im wesentlichen darin, dass der Schlitten in Maschinenlängsrichtung verlaufende Führungsstangen trägt, welche in rohr-förmige Führungen des ein Fahrwerk tragenden Maschinenrahmens eingreifen. Dadurch, dass das Konstruktionsprinzip für die Rahmenschlittenkonstruktion nunmehr so abgeändert wurde, dass die Führungsstangen mit dem Schlitten verbunden sind und die Rohre am Rahmen festgelegt sind, gelingt es, den Maschinenrahmen mit den Raupenfahrwerken besonders stabil bei relativ kurzen rohrförmigen Führungen zu gestalten und gleichzeitig den mit der Stange verbundenen Schlitten entsprechend kippbar zu führen, da die relativ langen Führungsstangen des Schlittens in relativ kurzen Rohrstücken des Maschinenrahmens geführt sind. Eine derartige Kippbarkeit kann noch dadurch verbessert werden, dass, wie es einer bevorzugten Weiterbildung der erfindungsgemäßen Ausbildung entspricht, die rohrförmigen Führungen gekrümmte Erzeugende unter Ausbildung einer balligen Innenkontur aufweisen. Die rohrförmigen Führungen eignen sich in besonders einfacher Weise zur Ausbildung besonders stabiler niedrigbauender Maschinenrahmen, wobei dieser Maschinenrahmen insgesamt relativ kurz gebaut sein kann, ohne die erforderliche Steifigkeit und Festigkeit zu verlieren. Bezüglich des Einsatzes von Förderern sind geringere Einschränkungen als bei Kastenprofilen hinzunehmen, welche den Schlitten bilden, da ja der Schlitten den Förderer in Maschinenlängsrichtung mitnimmt. Mit Vorteil ist die Ausbildung erfindungsgemäß deshalb so getroffen, dass der Schlitten als nach oben offene Rinne ausgebildet ist, in deren Seitenwangen die Schwenkachse für die vertikale Verschwenkung des Schrämarms gelagert ist. Eine derartige nach oben offene Rinne kann über einen relativ langen axialen Verschiebeweg verstellt werde, ohne dass es zu Kollisionen des Förderers mit Rahmenbauteilen des Maschinenrahmens kommt.The invention now aims to provide a tunneling machine with a low pitch frame slide construction which is suitable for particularly low seams and has improved dome trough handling. To achieve this object, the inventive design of the tunneling machine of the type mentioned essentially consists in that the carriage carries in the machine longitudinal direction extending guide rods, which engage in tubular guides of a chassis supporting machine frame. The fact that the design principle for the frame carriage construction has now been modified so that the guide rods are connected to the carriage and the tubes are fixed to the frame, it is possible to make the machine frame with the crawler tracks particularly stable at relatively short tubular guides and at the same time with the rod associated carriage to lead tiltably, since the relatively long guide rods of the carriage are guided in relatively short pipe sections of the machine frame. Such a tiltability can be further improved by the fact that, as is the case with a preferred development of the embodiment according to the invention, the tubular guides have curved generators to form a convex inner contour. The tubular guides are suitable in a particularly simple manner for the formation of particularly stable low-building machine frame, said machine frame can be constructed overall relatively short, without losing the required rigidity and strength. With regard to the use of conveyors are less restrictions than to accept box profiles, which the Form slide, since the carriage takes the conveyor in the machine longitudinal direction. Advantageously, the training according to the invention therefore made such that the carriage is designed as an upwardly open channel, in the side cheeks, the pivot axis is mounted for the vertical pivoting of the Schrämarms. Such an upwardly open channel can be adjusted over a relatively long axial displacement, without causing collisions of the conveyor with frame components of the machine frame.

In besonders vorteilhafter Weise ist die Ausbildung so getroffen, dass die rohrförmigen Führungen zwischen Raupenfahrwerken angeordnet sind und mit quer zur Rohrachse verlaufenden Streben oder Platten zu einem Rahmen verbunden sind, wodurch bei kleinen Abmessungen eine hohe Stabilität des Maschinenrahmens gewährleistet wird. Die rohrförmigen Führungen können hierbei sowohl mit dem Raupenfahrwerk als auch den Verbindungsplatten entsprechend verschweißt sein, wodurch sich eine besonders kompakte und verwindungssteife Konstruktion ergibt.In a particularly advantageous manner, the design is such that the tubular guides are arranged between crawler tracks and are connected to transverse to the tube axis struts or plates to form a frame, which ensures a high stability of the machine frame with small dimensions. The tubular guides can in this case be welded in accordance with both the crawler track and the connecting plates, resulting in a particularly compact and torsionally rigid construction.

Die kurze Bauweise erlaubt es gleichzeitig, den Maschinenrahmen selbst in axialer Richtung zu unterteilen und auch hier die Gelenkigkeit zu verbessern, was wiederum der Verbesserung der Mulden- und Kuppengängigkeit dient. Zu diesem Zweck ist mit Vorteil die Ausbildung so getroffen, dass an dem die Rohre umfassenden Rahmen ein um wenigstens eine quer zur Maschinenlängsrichtung verlaufende Schwenkachse schwenkbarer Rahmenteil gelenkig angeschlossen ist. Ein derartig im hinteren Teil der Maschine angeordneter gelenkig schwenkbarer Rahmenteil kann zur Erzielung der gewünschten Übergabehöhe des Förderers in Höhenrichtung angehoben werden, wobei eine verbesserte Kurvengängigkeit durch eine weitere Schwenkbarkeit eines Rahmenteils im hinteren Bereich der Maschine erzielt werden kann. Mit Vorteil ist dabei die Ausbildung so getroffen, dass an dem dem Schrämarm abgewandten hinteren Ende des Schlittens eine quer zur Maschinenlängsachse verlaufende Schwenkachse für den Förderer bzw. eine Förderrinne angeordnet ist, wodurch relativ schwere Bauteile, wie die Energieversorgung für die Antriebe der Maschine, in Kurven seitlich verschwenkt werden können. Gegenüber bekannten Konstruktionen stellt es einen wesentlichen Vorteil dar, alle Schwenkbarkeiten ohne Gefahr einer Kollision des Förderers mit anderen Maschinenbauteilen zu gewährleisten, wofür, wie bereits erwähnt, die Ausbildung mit Vorteil so getroffen ist, dass die Förderrinne über die gesamte Länge des Förderers als oben offene Rinne ausgebildet ist.The short design allows at the same time to divide the machine frame itself in the axial direction and also to improve the flexibility, which in turn serves to improve the Mulden- and Kuppengängigkeit. For this purpose, the training is advantageously made such that at the frame comprising the tubes a hinged to at least one transverse to the machine longitudinal direction pivot axis frame part is connected. An articulated pivotable frame part arranged in such a manner in the rear part of the machine can be raised in the vertical direction to achieve the desired transfer height of the conveyor, wherein improved cornering can be achieved by further pivotability of a frame part in the rear region of the machine. Advantageously, the training is made so that on the side facing away from the cutting arm the rear end of the carriage is arranged a transverse axis to the machine axis pivot axis for the conveyor or a conveyor trough, whereby relatively heavy components, such as the power supply for the drives of the machine can be pivoted laterally in curves. Compared to known constructions, it is a major advantage to ensure all pivoting without risk of collision of the conveyor with other machine components, for which, as already mentioned, the training is advantageously made so that the conveyor trough over the entire length of the conveyor as open top Gutter is formed.

Die Schwenkbarkeit des hinteren Maschinenteils bzw. des gelenkig mit dem Maschinenrahmen verbundenen schwenkbaren hinteren Rahmenteils kann noch dadurch verbessert werden, dass dieser hintere Rahmenteil kardanisch an dem die rohrförmige Führung aufweisenden Rahmenteil angeschlossen ist.The pivotability of the rear machine part or of the pivotally connected to the machine frame pivoting rear frame member can be further improved by the fact that this rear frame part is gimbal connected to the tubular guide having frame part.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. In dieser zeigen Fig.1 eine perspektivische Gesamtansicht der erfindungsgemäßen Maschine in schematischer Darstellung, Fig.2 den in Maschinenlängsrichtung verschiebbaren Rahmen in vergrößerter Darstellung, Fig.3 den Maschinenrahmen mit gelenkig am Maschinenrahmen angeschlossenem hinteren schwenkbaren Rahmenteil und Fig.4 einen Schnitt nach der Linie IV/IV der Fig.3, wobei in den Maschinenrahmen der Schlitten eingeschoben wurde.The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. In this show Fig.1 an overall perspective view of the machine according to the invention in a schematic representation, Fig.2 the displaceable in the machine longitudinal direction frame in an enlarged view, Figure 3 the machine frame with hinged on the machine frame rear hinged frame part and Figure 4 a section along the line IV / IV of Figure 3 , wherein in the machine frame, the carriage has been inserted.

In Fig.1 ist eine Vortriebsmaschine 1 dargestellt, deren Raupenfahrwerk 2 mit einem Maschinenrahmen 3 verbunden ist. Auf diesem Maschinenrahmen ist ein Schlitten 4 in Maschinenlängsrichtung verschiebbar, wobei am Schlitten 4 um eine mit 5 schematisch angedeutete horizontale Schwenkachse ein Ausleger bzw. Schrämarm 6 mit einer rotierbar gelagerten Schrämwalze 7 in Höhenrichtung verschwenkbar angelenkt ist.In Fig.1 is a tunneling machine 1 shown, the crawler chassis 2 is connected to a machine frame 3. On this machine frame, a carriage 4 is displaceable in the machine longitudinal direction, wherein a boom or Schrämarm 6 with a rotatably mounted cutting roller 7 is pivoted in the vertical direction on the carriage 4 to a schematically indicated with 5 horizontal pivot axis.

Am Hinterende des Schlittens 4, welcher ein nach oben offenes rinnenförmiges Profil aufweist, ist um eine Schwenkachse 8 in Höhenrichtung verschwenkbar ein weiterer Rahmenteil 9 vorgesehen, mittels welchem ein in der Rinne gelagerter Förderer in Höhenrichtung verschwenkt werden kann, um die gewünschte Abwurfhöhe einzustellen. An dem Maschinenrahmen 2 ist aber auch ein weiterer schwenkbarer hinterer Rahmenteil 10 angeordnet, welcher in Kurven seitlich ausgeschwenkt werden kann, wie bei nachfolgenden Figuren noch näher erläutert wird.At the rear end of the carriage 4, which has an upwardly open trough-shaped profile, a further frame part 9 is provided pivotably about a pivot axis 8 in the height direction, by means of which a conveyor mounted in the trough can be pivoted in the vertical direction to set the desired discharge height. On the machine frame 2 but also another pivotable rear frame member 10 is arranged, which can be swung laterally in curves, as will be explained in more detail in the following figures.

In Fig.2 ist der Schlitten 4 vergrößert dargestellt, wobei der Auslegerarm 6 abgenommen wurde. Deutlich erkennbar ist der mit dem Schlitten 4 verbundene Stirnträger 11, welcher Führungsstangen 12 trägt. Diese Führungsstangen 12 werden in entsprechende rohrförmige Führungen des Maschinenrahmens eingesetzt, wobei diese rohrförmigen Führungen in Fig.3 mit 13 bezeichnet sind. In Fig.3 ist nun der Maschinenrahmen mit dem Raupenfahrwerk 2 ersichtlich, welcher aus einem ersten die rohrförmigen Führungen 13 tragenden Rahmen 3 und einem um eine im wesentlichen vertikale Achse 14 schwenkbaren Rahmenteil 10 besteht. Bei der Darstellung nach Fig.3 sind Schwenkzylinder 15 für die Höhenverschwenkung des Auslegerarms 6, wie er in Fig.1 ersichtlich ist, ebenso dargestellt, wie weitere Schwenkzylinder 16 für eine entsprechende Verstellung des zweiten Rahmenteils 10 gegenüber dem mit dem Raupenfahrwerk verbundenen ersten Rahmenteil 3. Zu diesem Zweck ist die schematisch mit 14 angedeutete Achse nicht als reine vertikale Schwenkachse sondern als ballige Lagerung ausgebildet, welche eine kardanische Verschenkbarkeit auch quer zur Achse 14 erlaubt. Ebenso ist die Innenkontur der rohrförmigen Führungen nicht von geraden Erzeugenden gebildet, sondern vielmehr von gekrümmten Erzeugenden, sodass die Stangen 12 mit entsprechendem Spiel in den Führungen 13 geführt sind, welche eine Kippbewegung um eine im wesentlichen parallel zur Bodenebene verlaufende Achse zulassen.In Fig.2 the carriage 4 is shown enlarged, the boom 6 has been removed. Clearly visible is connected to the slide 4 end support 11, which carries guide rods 12. These guide rods 12 are inserted into corresponding tubular guides of the machine frame, these tubular guides in Figure 3 are denoted by 13. In Figure 3 Now, the machine frame with the crawler chassis 2 can be seen, which consists of a first tubular guides 13 supporting the frame 3 and a pivotable about a substantially vertical axis 14 frame part 10. In the presentation after Figure 3 are pivot cylinder 15 for the Höhenverschwenkung of the boom 6, as in Fig.1 can be seen, as well as other pivoting cylinder 16 for a corresponding adjustment of the second frame member 10 relative to the connected to the crawler chassis first frame part 3. For this purpose, the schematically indicated with 14 axis is not designed as a pure vertical pivot axis but as spherical bearing, which a cardan Verschenkbarkeit also transversely to the axis 14 allowed. Likewise, the inner contour of the tubular guides is not formed by straight generatrix, but rather by curved generatrix, so that the rods 12 are guided with corresponding play in the guides 13, which allow a tilting movement about an axis substantially parallel to the ground plane.

Bei der Darstellung nach Fig.4 ist nun die Rahmenkonstruktion im Schnitt ersichtlich, wobei in den rohrförmigen Führungen 13 nunmehr die Stangen 12 des Schlittens 4 eingeschoben sind. Die rohrförmigen Führungen sind mit dem Raupenfahrwerk 2 jeweils verschweißt und miteinander über Platten 17 zu einem besonders biegesteifen kastenförmigen Rahmenbauteil verbunden. Die in die rohrförmigen Führungen 13 eingesteckten Führungsstangen 12, deren axiale Länge größer ist als die axiale Länge der rohrförmigen Führungen, können mit entsprechendem Spiel in den rohrförmigen Führungen geführt sein und es ist in Fig.4 deutlich ersichtlich, dass der Schlitten im Querschnitt ein nach oben offenes U-Profil ausbildet und somit eine nach oben offene Rinne für den Förderer darstellt.In the presentation after Figure 4 Now the frame construction is shown in section, wherein in the tubular guides 13 now the rods 12 of the carriage 4 are inserted. The tubular guides are respectively welded to the crawler track 2 and connected to each other via plates 17 to a particularly rigid box-shaped frame member. The inserted into the tubular guides 13 guide rods 12, whose axial length is greater than the axial length of the tubular guides, can be performed with appropriate play in the tubular guides and it is in Figure 4 clearly seen that the carriage in cross-section forms an upwardly open U-profile and thus represents an upwardly open channel for the conveyor.

Durch überaus niedrige Bauweise bei gleichzeitiger maximaler Gelenkigkeit wird bei dieser Ausbildung die Kuppen- und Muldengängigkeit ebenso wie die Kurvengängkeit der Vortriebs- bzw. Schrämmaschine wesentlich verbessert.Due to extremely low construction and maximum flexibility at the same time the dome and Muldengängigkeit as well as the Kurvengängkeit the propulsion or cutting machine is significantly improved in this training.
