Description

Die Erfindung betrifft eine Einrichtung zum Verstellen und Verlagern einer Ladevorrichtung für ein Gewinnungsorgan, insbesondere als Förderschnecke ausgebildetes Ladeorgan, das ggf. gleichzeitig das Gewinnungsorgan bildet, wobei das Ladeorgan mit mindestens einem außerhalb des Arbeitsbereiches des Gewinnungsorganes angeordneten Führungselement für das abzufördernde Material zusammenwirkt, welches widerum mit einer Öffnung versehen ist, durch die das Material auf ein im rückwärtigen Bereich des Führungselementes angeordnetes Fördermittel übergeben wird, wobei die Ladevorrichtung mittels einer Aufhängung an einem dahinter angeordneten, vorzugsweise auf Raupen verfahrbaren Gerät, quer davor liegend, angelenkt ist.The invention relates to a device for adjusting and relocating a loading device for an extraction member, in particular a loading member designed as a screw conveyor, which optionally also forms the extraction member, the loading member cooperating with at least one guide element arranged outside the working area of the extraction member for the material to be removed, which in turn is provided with an opening through which the material is transferred to a conveying means arranged in the rear region of the guide element, the loading device being articulated by means of a suspension to a device arranged behind it, preferably movable on caterpillars, lying transversely in front of it.

Durch die DE-PS 3323395 sowie die DE-PS 2517122 sind Vortriebsmaschinen für Bergbaustrecken und Tunnelstrecken bekannt. Die Ladeorgane sind als Förderschnecken ausgebildet, die mit Tragrahmen beiderseits der Fördervorrichtung armartig schwenkbar sind. In den Tragarmen sind im rückwärtigen Bereich der Förderschnecken und zu diesen parallel laderinnenbildende Führungselemente angeordnet. Die Förderschnecken sind auf ihrem Schneckensteg zumindest bereichsweise mit Brechwerkzeugen besetzt, wobei die Führungselemente in diesem Bereich als Brechwiderlager dienen. Die Tragrahmen sind unabhängig voneinander um ihre vertikalen Achsen schwenkbar, um so eine gewisse Kurvengängikeit der gesamten Maschine zu gewährleisten. Das eigentliche Gewinnungsorgan ist vor den Förderschnecken angeordnet, so daß hier eine Trennung zwischen den Vorgängen Gewinnen und Abtransportieren gegeben ist.Through the DE-PS 3323395 and DE-PS 2517122 tunneling machines for mining routes and tunnel routes are known. The loading elements are designed as screw conveyors, which can be swiveled arm-like on both sides of the conveying device with a supporting frame. In the support arms, in the rear area of the screw conveyors and guide elements forming loader parallel to them, are arranged. The screw conveyors are at least partially equipped with crushing tools on their screw web, the guide elements serving as crushing abutments in this area. The support frames can be swiveled independently of one another about their vertical axes in order to ensure that the entire machine can move around curves. The actual extraction organ is arranged in front of the screw conveyors, so that there is a separation between the extraction and removal processes.

Vortriebsmaschinen der angesprochenen Gattung eignen sich gut im Untertagebau, wo lediglich geringe Abtragshöhen gegeben sind. Vielfach sind den Ladeorganen die eigentlichen Gewinnungsorgane vorgeschaltet, so daß die Ladeorgane selber nur das zu Boden fallende abgehauene Material aufzunehmen und ggf. noch zerkleinern müssen.Tunneling machines of the type mentioned are well suited for underground mining, where there are only low removal heights. In many cases, the actual extraction organs are connected upstream of the loading organs, so that the loading organs themselves only have to take up the cut material falling to the ground and possibly have to shred them.

Der Erfindung liegt die Aufgabe zugrunde, eine im gattungsbildenden Teil des Hauptpatentanspruches beschriebene Ladevorrichtung dahingehend weiterzubilden, daß einerseits ein kontinuierlicher Schneid- und Förderprozess der Ladevorrichtung bzw. des Gewinnungsorganes erreicht wird.The invention has for its object to develop a loading device described in the generic part of the main patent claim in such a way that on the one hand a continuous cutting and conveying process of the loading device or the extraction member is achieved.

Andererseits soll das Lade- bzw. das Gewinnungsorgan zum Abbau auch höhergelegenerer Materialien heb- und senkbar sowie in Querrichtung verstellbar sein. Ferner soll in allen Abbausituationen gewährleistet werden, daß das abzufördernde Gut bei der Übergabe auf einen hinter der Ladevorrichtung angeordneten Abförderer nicht auf den Erdboden fällt und so ein Zurückfahren des Gerätes zum neuerlichen Einsammeln des durchgefallenen Haufwerkes notwendig macht. Darüberhinaus soll der konstruktive Aufbau vereinfacht werden.On the other hand, the loading or extracting element for dismantling higher-lying materials should also be able to be raised and lowered and adjustable in the transverse direction. Furthermore, it should be ensured in all dismantling situations that the goods to be removed do not fall to the ground when they are handed over to a discharge conveyor arranged behind the loading device, thus making it necessary to return the device to collect the failed pile again. In addition, the structural design should be simplified.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das aus Förderschnecke und Führungselement gebildete Ladeorgan bzw. das Gewinnungsorgan auf der Vorderseite der Aufhängung um eine horizontale Achse drehbar gelagert ist und daß die Aufhängung selber und damit auch das Ladeorgan bzw. das Gewinnungsorgan geräteseitig um einen, ebenfalls horizontal verlaufenden, jedoch in einer anderen Ebene als die horizontale Achse angeordneten Achszapfen schwenkbar ist.This object is achieved in that the loading member formed from the screw and guide element or the extraction member is rotatably mounted on the front of the suspension around a horizontal axis and that the suspension itself and thus also the loading member or the extraction member on the device side by one, also horizontally extending, but arranged in a different plane than the horizontal axis pivot pin.

Wie bereits im gattungsbildenden Teil des Hauptpatentanspruches angesprochen, kann das Ladeorgan gleichzeitig das Gewinnungsorgan bilden oder aber als separates Bauteil ausgebildet sein, so daß sich der gegenständliche Schutz auf beide Varianten erstreckt.As already mentioned in the generic part of the main patent claim, the loading device can simultaneously form the extraction device or can be designed as a separate component, so that the objective protection extends to both variants.

Durch die erfindungsgemäßen Merkmale wird sichergestellt, daß bei verhältnismäßig einfachem konstruktivem Aufbau in jeder Höhen- oder Neigungsstellung des Ladeorganes bzw. des Gewinnungsorganes ein kontinuierlicher Schneid- und Fördervorgang durchführbar ist.The features of the invention ensure that with a relatively simple structural design, a continuous cutting and conveying process can be carried out in any height or inclination position of the loading member or of the extraction member.

Vorzugsweise ist die Aufhängung gabelförmig ausgebildet und die Ladevorrichtung ist im Bereich der freien Enden der Gabel - also dem abzubauenden Material zugewandt - um eine horizontal sich zwischen den Gabelschenkeln erstreckende horizontale Achse schwenkbar, wobei aus baulichen Gründen die freien Gabelschenkel, sich, ausgehend vom Gerät, geneigt verlaufend, in Richtung der horizontalen Achse erstrecken. Die so gebildeten relativ kurzen Hebelwege erlauben zum einen eine kompakte Bauform und zum anderen ein leichteres Anheben der Ladevorrichtung bzw. des Gewinnungsorganes um die horizontale Achse herum. Zum Drehen der Ladevorrichtung um die horizontale Achse wird mindestens ein außerhalb derselben gelenkig an der Gabel und mit seinem anderen Ende an einer vertikalen Verlängerung des Führungselementes befestigter Hydraulikzylinder verwendet.The suspension is preferably fork-shaped and the loading device can be pivoted in the region of the free ends of the fork - that is to say the material to be dismantled - about a horizontal axis extending between the fork legs, with the free fork legs, for structural reasons, starting from the device, extend inclined in the direction of the horizontal axis. The relatively short lever paths formed in this way allow, on the one hand, a compact design and, on the other hand, easier lifting of the loading device or the extraction member about the horizontal axis. To rotate the loading device about the horizontal axis, at least one hydraulic cylinder is used that is articulated outside the fork and with its other end on a vertical extension of the guide element.

Einem weiteren Gedanken der Erfindung gemäß ist das Fördermittels, welches das durch die Ladevorrichtung zugeführte Haufwerk übernimmt, aus einem Förderband gebildet, dessen eine Umlenkung ebenfalls um die zwischen den Gabelschenkeln sich erstreckende horizontale Achse erfolgt. Durch diese Maßnahme wird die kompakte Bauform noch verbessert, da die ansonsten notwendige separate Umlenkrolle entfallen kann, zumal sie unmittelbar durch die horizontale Achse selber gebildet werden kann. Vorzugsweise ist die horizontale Achse im Bereich der Gabelschenkel mittels Gleitlagern verlagert, um so auch eventuelle Querbewegungen ohne Beschädigungen aufnehmen zu können.According to a further concept of the invention, the conveying means, which takes over the bulk material supplied by the loading device, is formed from a conveyor belt, the deflection of which likewise takes place about the horizontal axis extending between the fork legs. The compact design is further improved by this measure, since the otherwise required separate deflection roller can be dispensed with, especially since it can be formed directly by the horizontal axis itself. The horizontal axis in the region of the fork legs is preferably displaced by means of slide bearings in order to be able to absorb any transverse movements without damage.

Wie bereits oben angesprochen, ist die Gabel und somit das Ladeorgan bzw. das Gewinnungsorgan um einen Achszapfen, der entlang der Gerätemitte horizontal verläuft, schwenkbar. Die Schwenkbewegung wird, als bevorzugte Weiterbildung des Erfindungsgedankens, durch mindestens einen außerhalb der Gerätemitte angeordneten vertikalen Hubzylinder erzeugt.As already mentioned above, the fork and thus the loading element or the extraction element can be pivoted about an axle journal that runs horizontally along the center of the device. As a preferred development of the inventive concept, the pivoting movement is generated by at least one vertical lifting cylinder arranged outside the center of the device.

Der Achszapfen ist vorzugsweise im Bereich der Gabelaufhängung gleitgelagert.The axle journal is preferably slidably mounted in the area of the fork suspension.

Die beim Abbau des Materials auftretenden Reaktionskräfte in Längsrichtung des Gerätes können bewirken, daß der ohnehin zwischen den Stirnflächen des Gerätes und der Gabel vorhandene geringe Spalt durch Verkantung der Gabel in der einen oder anderen Richtung geschlossen wird und die Bauteile unter metallischer Berühung reibend aneinanderliegen. Einerseits kann es so zu Beschädigungen an den aneinanerreibenden Flächen kommen und zum anderen wird der Achszapfen in Mitleidenschaft gezogen, so daß sich hier später unerwünschte Exentrizitäten einstellen können.The reaction forces occurring in the longitudinal direction of the device when the material is broken down can cause the small gap that is present anyway between the end faces of the device and the fork to be closed by tilting the fork in one direction or the other and the components rubbing against one another with metallic contact. On the one hand, this can result in damage to the surfaces rubbing against one another, and on the other hand, the axle journal is affected, so that undesirable eccentricities can occur later on.

Um dem auf einfache Weise Abhilfe zu schaffen, wird vorgeschlagen, daß zur Reduzierung des zwischen Gabel- und Gerät vorhandenen Spaltes im stirnseitigen Bereich der Gabel und/oder im korrespondierenden Gerätebereich Gleitkörper angeordnet sind. Diese können vorzugsweise im Bereich der Gabel- bzw. Geräteaußenkanten angeordnet werden. Durch diese Maßnahmen können die Kräfte wesentlich besser von der Ladevorrichtung bzw. dem Gewinnungsorgan auf das Gerät übertragen werden, wobei gleichzeitig der Achszapfen und die Gabel entlastet werden.In order to remedy this in a simple manner, it is proposed that, in order to reduce the gap between the fork and the device, sliding bodies are arranged in the front area of the fork and / or in the corresponding device area. These can preferably be arranged in the area of the fork or device outer edges. Through these measures, the forces can be transferred much better from the loading device or the extraction device to the device, with the axle journal and the fork being relieved at the same time.

Die Erfindung ist in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:

  • Fig. 1 Tagebaugerät mit einem als Gewinnungsorgan ausgebildeten Ladeorgan
  • Fig. 2 Schematische Darstellung der Gabel und des Gerätes mit dazwischen angeordneten Gleitkörpern
The invention is illustrated in the drawing and is described as follows. Show it:
  • Fig. 1 opencast mining device with a loading organ designed as a mining organ
  • Fig. 2 Schematic representation of the fork and the device with sliding bodies arranged between them

Fig. 1 zeigt ein Tagebaugerät 1, welches im wesentlichen folgende Bauteile aufweist: Ein Raupenfahrwerk 2 mit Unterbau 3, einem darauf angeordneten Oberbau 4, einem kombinierten Gewinnungs- und Ladeorgan 5, einem Führungselement 6, einem Antrieb 7 für das Gewinnungs- und Ladeorgan 5, einer Aufhängung 8 für das Gewinnungs- und Ladeorgan 5 sowie einem als Förderband ausgebildeten Fördermittel 9. Die Funktionsweise des Tagebaugerätes 1 stellt sich etwa wie folgt dar: Das Gerät 1 fährt mit dem quer davorliegenden Gewinnungs- und Ladeorgan 5 in das abzubauende Material 10 hinein. Das Gewinnungs- und Ladeorgan 5 ist als gegensinnig zur Mitte hin fördernde Förderschnecke (nicht dargestellt) ausgebildet, die vorzugsweise im Bereich ihrer äußeren Umfangsfläche mit Brechelementen in Form von Meißeln oder dgl. besetzt ist. Das Gewinnungs- und Ladeorgan 5 arbeitet unterschlächtig, d.h. das gewonnene Material wird zwischen dem Gewinnungs- und Ladeorgan 5 und dem dahinter angeordneten Führungselement 6 zur Mitte gefördert und durch eine hier vorgesehene Öffnung 11 dem geräteseitig vorgesehenen Förderband 9 übergeben. Das kombinierte Gewinnungs- und Ladeorgan 5 sowie das Führungselement 6 sind im Bereich der, aus einer Gabel gebildeten Aufhängung 8 um eine horizontale Achse 12 drehbar gelagert.1 shows a surface mining device 1 which essentially has the following components: a crawler track 2 with a substructure 3, a superstructure 4 arranged thereon, a combined extraction and loading element 5, a guide element 6, a drive 7 for the extraction and loading element 5 , a suspension 8 for the extraction and loading element 5 and a conveyor 9 designed as a conveyor belt. The operation of the opencast mining device 1 is approximately as follows: The device 1 moves with the extraction and loading element 5 lying transversely in front into the material 10 to be mined . The extraction and loading element 5 is designed as a screw conveyor (not shown) which conveys in the opposite direction and is preferably equipped with breaking elements in the form of chisels or the like in the region of its outer peripheral surface. The extraction and loading member 5 works undershot, i.e. the material obtained is conveyed to the center between the extraction and loading element 5 and the guide element 6 arranged behind it and is passed through an opening 11 provided here to the conveyor belt 9 provided on the device. The combined extraction and loading element 5 and the guide element 6 are rotatably mounted about a horizontal axis 12 in the area of the suspension 8 formed from a fork.

Die Aufhängung selber und damit auch das Gewinnungs- und Ladeorgan 5 ist geräteseitig um einen ebenfalls horizontal verlaufenden jedoch in einer anderen Ebene als die horizontale Achse 12 angeordneten Achszapfen 13 in Querrichtung schwenkbar. Die horizontale Achse 12 ist zwischen den Endbereichen 14 der Gabelschenkel angeordnet. Zum Drehen des Gewinnungs- und Ladeorganes 5 um die horizontale Achse 12 dienen Hydraulikzylinder 15, die einerseits gelenkig an der Gabel 8 und andererseits an einer vertikalen Verlängerung 16 des Führungselementes 6 angeordnet sind. Während der Betätigung der Hydraulikzylinder 15 schwenken diese bei gleichzeitigem Anheben des Gewinnungs- und Ladeorganes 5 um den gabelseitigen Gelenkpunkt 17.The suspension itself and thus also the extraction and loading element 5 can be pivoted in the transverse direction on the device side about an axis pin 13 which also runs horizontally but is arranged in a different plane than the horizontal axis 12. The horizontal axis 12 is arranged between the end regions 14 of the fork legs. Hydraulic cylinders 15, which are articulated on the fork 8 on the one hand and on the other hand on a vertical extension 16 of the guide element 6, serve to rotate the extraction and loading element 5 about the horizontal axis 12. During the actuation of the hydraulic cylinders 15, these pivot about the fork-side pivot point 17 while simultaneously lifting the extraction and loading element 5.

Um eine kompakte Bauweise zu erreichen, ist die Umlenkrolle 18 des Förderbandes 9 ebenfalls um die horizontale Achse 12 herumgelegt. Ein Herabfallen des gewonnen Materials auf den Erdboden 20 wird durch weitere nicht dargestellte Organe verhindert.
Die Schwenkbewegung der Gabel 8 um den Achszapfen 13, der vorzugsweise entlang der Gerätemittellinie verläuft, wird durch einen außerhalb der Gerätemittellinie, sich zwischen dem Oberbau 4 und der Gabel 8 erstreckenden Hubzylinder 21 erzeugt.In order to achieve a compact design, the deflection roller 18 of the conveyor belt 9 is also placed around the horizontal axis 12. Falling of the material obtained on the ground 20 is prevented by other organs, not shown.
The pivoting movement of the fork 8 around the axle journal 13, which preferably runs along the device center line, is generated by a lifting cylinder 21 extending outside the device center line, between the superstructure 4 and the fork 8.

Figur 2 zeigt einen Teilausschnitt der Gabel 8. Sie besteht aus einem quer vor dem Gerät angeordneten Schenkel 24 sowie jeweils einem seitlichen Schenkel 25. Die Gabel 8 ist geräteseitig um den schon angesprochenen Achszapfen 13 (nur angedeutet) schwenkbar und in diesem Bereich gleitgelagert 26. In den Endbereichen 14 der Gabelschenkel 25 sind zur Aufnahme der horizontalen Achse 12 Gleitlager 27 vorgesehen. Zur Schonung des Achszapfens 13 bei Reaktionskräften F, die entgegen der Schneidrichtung wirken, ist in den Außenbereichen 28,29 sowohl des Gabelschenkels 24 als auch der korrespondierenden Stirnseite 30 des Gerätes 1 jeweils ein Gleitelement 31, 32 vorgesehen. Durch diese Maßnahme wird einerseits der ohnehin vorhandene Spalt c reduziert und zum anderen eine metallische Berührung der Flächen 28 und 30 vermieden, wobei die eigentliche Berührung zwischen den Gleitelementen 31 und 32 stattfindet. Da die Verkantung nunmehr nahezu ausgeschlossen ist, werden der Achszapfen 13 und auch die Gabel 8 kaum noch belastet.FIG. 2 shows a partial section of the fork 8. It consists of a leg 24 arranged transversely in front of the device and a respective side leg 25. The fork 8 can be pivoted on the device side about the already mentioned axle journal 13 (only indicated) and is supported in this area by sliding bearings 26. In the end regions 14 of the fork legs 25 12 plain bearings 27 are provided for receiving the horizontal axis. In order to protect the journal 13 from reaction forces F which act counter to the cutting direction, a sliding element 31, 32 is provided in the outer regions 28, 29 of both the fork leg 24 and the corresponding end face 30 of the device 1. This measure on the one hand reduces the gap c, which is present anyway, and on the other hand avoids metallic contact of the surfaces 28 and 30, the actual contact between the sliding elements 31 and 32 taking place. Since the tilting is now almost impossible, the journal 13 and the fork 8 are hardly loaded.
