Abstract

A charging device for an extracting member is proposed, in particular a screw conveyor (1), which interacts with a guide element which, as an auxiliary means, transports the extracted material to a passage opening and transfers it there to a discharge conveyor. So that a continuous conveying flow can be created, the lower area of the guide element (4) is designed in such a way that it can follow lifting or swivelling movements of the extracting member or the charging device (1). <IMAGE>

Description

Die Erfindung betrifft eine Ladevorrichtung für ein Gewinnungsorgan, insbesondere als Förderschnecke aus­gebildetes Ladeorgan, die ggf. gleichzeitig das Gewinnungs­organ bildet, wobei die Ladevorrichtung mit mindestens einem ausßerhalb des Arbeitsbereiches des Gewinnungs­organes angeordneten Führungselement für das abzufördernde Material zusammenwirkt.The invention relates to a loading device for a extraction member, in particular a loading member designed as a screw conveyor, which optionally also forms the extraction member, the loading device cooperating with at least one guide element arranged outside the working area of the extraction member for the material to be removed.

Durch die DE-PS 3323395 ist eine Vortriebsmaschine für Berg­baustrecken und Tunnelstrecken vorbekannt. Die Ladewerkzeuge sind als Ladeschnecken ausgebildet, die mit Tragrahmen beider­seits der Fördervorrichtung armartig schwenkbar sind. In den Tragarmen sind im rückwärtigen Bereich der Ladeschnecken und zu diesen parallel laderinnenbildende Schurren angeordnet. Die Ladeschnecken sind auf ihrem Schneckensteg zumindest bereichsweise mit Brechwerkzeugen besetzt, wobei die Schurren in diesem Bereich als Brechwiderlager dienen. Somit wirkt die Ladevorrichtung gleichzeitig als Gewinnungsorgan. Die Tragrahmen sind unabhängig voneinander um ihre vertikalen Achsen schwenkbar sein, um so eine gewisse Kurvengängigkeit der gesamten Maschine zu gewährleisten. Vortriebsmaschinen der angesprochenen Gattung eignen sich gut im Untertagebau, wo lediglich geringe Abtragshöhen gegeben sind. Vielfach sind den Ladevorrichtungen die eigentlichen Gewinnungsorgane vorge­schaltet, so daß die Ladevorrichtungen selber nur das zu Boden fallende abgehauene Material aufnehmen und ggf. noch zerkleinern müssen.DE-PS 3323395 a tunneling machine for mining and tunnel routes is already known. The loading tools are designed as loading screws which can be swiveled arm-like on both sides of the conveying device with a supporting frame. The loading augers and chutes forming loader parallel to them are arranged in the rear arms in the rear region. The loading screws are at least partially equipped with crushing tools on their screw web, the chutes serving as crushing abutments in this area. The loading device thus simultaneously acts as an extraction organ. 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. 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 elements are connected upstream of the loading devices, so that the loading devices themselves only have to pick up the cut material falling to the ground and possibly have to shred them.

Beim Einsatz derartiger Gewinnungsorgane im Tagebau sind je­doch Arbeitsflächen mit Abtragshöhen in der Größe des zwei- bis dreifachen Schneckendurchmessers nichts ungewöhnliches. Das dabei im Hochschnitt arbeitende Gewinnungsorgan löst das Material aus der Wand, läßt es auf den Erdboden fallen, wobei das Material - wie bereits oben angesprochen - von Ladevorrichtungen aufge­nommen wird.When using such extraction elements in open-cast mining, however, work surfaces with removal heights in the size of two to three times the screw diameter are not uncommon. The extraction organ, which works in a high cut, releases the material from the wall and lets it fall to the ground, the material being - as already mentioned above - taken up by loading devices.

Bei diesem Verfahren ist eine zeitlich begrenzte Zwischen­lagerung vor dem Ladeschild unumgänglich. Dadurch wird der Gesamtwirkungsgrad verschlechtert und zusätzliche Verluste infolge seitlich abfließenden Materiales unvermeidbar.With this method, temporary storage in front of the loading plate is essential. As a result, the overall efficiency deteriorates and additional losses due to laterally flowing material are unavoidable.

Der Erfindung liegt, ausgehend vom gattungsbildenden Teil des Hauptpatentanspruches, die Aufgabe zugrunde, die Nach­teile des Standes der Technik zu beseitigen und einen konti­nuierlichen Förderfluß zu schaffen.The invention is based on the generic part of the main patent claim, the task of eliminating the disadvantages of the prior art and creating a continuous flow of funding.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Führungselement bzw. damit zusammenwirkende Bauteile den Hub- ­oder Schwenkbewegungen des Gewinnungsorganes bzw. der Lade­vorrichtung nachführbar ist bzw. sind. Durch diese Maßnahme wird erreicht, daß in jeder Höhenstellung der Ladevorrichtung bzw. des Gewinnungsorganes eine kontinuierliche Abförderung des gewonnenen Materials sichergestellt ist. Der Umweg über das Zwischenlager "Erdboden" wird somit umgangen, wobei der Gesamtwirkungsgrad in nicht unerheblicher Weise gesteigert werden kann. Die Nachführung erfolgt hierbei vorzugsweise zwangsläufig, d.h. simultan zur Hub- bzw. Schwenkbewegung.This object is achieved in that the guide element or components interacting therewith can or are trackable to the lifting or pivoting movements of the extraction member or the loading device. This measure ensures that a continuous removal of the material obtained is ensured at any height position of the loading device or of the extraction member. The detour via the "Erdboden" interim storage facility is thus avoided, the overall efficiency being able to be increased in a not inconsiderable manner. The tracking is preferably inevitable, i.e. simultaneous to the lifting or swiveling movement.

Eine Variante der Erfindung zeigt auf, daß die Bauteile etwa plattenförmig ausgebildet sind. Die Platten sind unterhalb des Führungselementes längsbeweglich angeordnet und sind vor­zugsweise zumindest in ihren äußeren Endbereichen durch Rollen oder Gleitführungen längsbeweglich gelagert. In Abhängigkeit von dem sich kontinuierlich auf- und abbewegenden Gewinnungs­organ erfolgt eine Zustellbewegung des Führungselementes. Diese Vorrichtung ist auch im Untertagebau einsetzbar, da hiermit nur geringere Abtragshöhen erfaßt werden können.A variant of the invention shows that the components are approximately plate-shaped. The plates are arranged to be longitudinally movable below the guide element and are preferably mounted to be longitudinally movable at least in their outer end regions by rollers or sliding guides. Depending on the extraction organ moving up and down continuously, the guide element is advanced. This device can also be used in underground construction, since it can only be used to detect lower removal heights.

Alternativ dazu wird vorgeschlagen, die mit dem Führungselement zusammenwirkenden Bauteile als Schalensegmente mit definiertem Krümmungsradius auszubilden, die einander in Umfangsrichtung überlappen und zumindest teilweise in Umfangsrichtung beweglich ausgebildet sind.As an alternative to this, it is proposed to design the components interacting with the guide element as shell segments with a defined radius of curvature, which overlap one another in the circumferential direction and are at least partially movable in the circumferential direction.

Oberhalb des Führungselementes ist analog zum Stand der Technik eine Öffnung vorgesehen, durch die das Material einen Band- oder Plattenförderer zum weiteren Abtransport zugeführt wird.Analogously to the prior art, an opening is provided above the guide element, through which the material is fed to a belt or plate conveyor for further removal.

Einem weiteren Gedanken der Erfindung gemäß weist das Führungselement einen gerundeten Querschnitt auf und dient im bodenseitigen Aufnahmebereich des Gewinnungsorganes als Aufnahmeelement für die Schalensegmente. Eine solche Vor­richtung ist universell sowohl für den direkten Vortrieb in Längsrichtung geeignet als auch für das Abhauen mittels Hub- und Schwenkbewegungen des Gewinnungsorganes einsetzbar.According to a further idea of the invention, the guide element has a rounded cross section and serves as a receiving element for the shell segments in the bottom receiving region of the extraction member. Such a device is universally suitable both for direct propulsion in the longitudinal direction and for cutting off by means of lifting and swiveling movements of the extraction member.

Zumindest das dem Arbeitsbereich des Gewinnungsorganes bzw. der Ladevorrichtung zugewandte Schalensegment ist mit definiertem radialem Abstand um die Horizontalachse des Gewinnungsorganes bzw. der Ladevorrichtung drehbar gelagert, wobei sich zwischen der inneren Umfangsfläche der Schalensegmente und den zugehörigen Lagern Verbindungstreben erstrecken. Die Aufhängung bzw. Lagerung der mit dem Führungselement zusammenwirkenden Bauteile erfolgt vorzugsweise im Bereich der Tragkonstruktion eines Fahrwerkes oder dgl.At least the shell segment facing the work area of the extraction element or the loading device is rotatably supported at a defined radial distance about the horizontal axis of the extraction element or the loading device, connecting struts extending between the inner peripheral surface of the shell segments and the associated bearings. The suspension or mounting of the components interacting with the guide element is preferably carried out in the area of the supporting structure of a chassis or the like.

Es wird weiterhin vorgeschlagen, die Schalensegmente in ihren Endbereichen (in Umfangsrichtung gesehen) mit radialen Ansätzen zu versehen, die Anschlagflächen für das Ein- bzw. das Aus­fahren der Schalensegmente bilden. Die Radialansätze greifen klauenartig ineinander und sind zumindest teilweise in ent­sprechenden Führungsnuten angeordnet. Somit kann ein in Um­fangsrichtung teleskopartiges Aus- bzw. Einfahren bei geringem Platzbedarf gewährleistet sein. Durch diese Anrodnung wird sichergestellt, daß unabhängig von der Abtragshöhe das ge­wonnene Material immer gleich in Richtung der Öffnung abge­fördert werden kann, ohne daß zwischendurch ein wesentlicher Materialverlust eintritt.It is further proposed to provide the shell segments in their end regions (seen in the circumferential direction) with radial shoulders which form stop surfaces for the retraction or extension of the shell segments. The radial lugs engage in a claw-like manner and are at least partially arranged in corresponding guide grooves. A telescopic extension or retraction in the circumferential direction can thus be ensured with a small space requirement. This arrangement ensures that irrespective of the removal height, the material obtained can always be removed in the same direction in the direction of the opening, without significant material loss occurring in between.

Je nach zu gewinnendem Material kann es sinnvoll sein, daß der radiale Spalt zwischen den schalenförmigen Führungs­elementen und dem Gewinnungsorgan gleichbleibend ausgebildet ist. Üblicherweise wird das Material während des Ladevor­ganges noch gebrochen. Hier könnte es von Vorteil sein, das dem Arbeitsbereich zunächst gelegene Schalensegment so zu führen, daß ein etwa trichterförmig sich verjüngender Auf­nahmebereich gebildet wird. Die Längs- bzw. die Drehbe­wegung der rinnenförmigen Führungselemente erfolgt vorzugs­weise mittels Schubelementen, wie z.B. Hydraulikzylindern, Spindeln, Zahnstangen oder dgl. In beiden bevorzugten An­wendungsfällen kann die Verstellbewegung der Führungsele­mente durch Kontaktschalter oder durch optische Schaltein­richtungen realisiert werden. Dadurch wird in Abhängigkeit von der Schüttiefe der Hub eingestellt bzw. die Anpassung an die unregelmässig verlaufende Arbeitsfläche erreicht.Depending on the material to be extracted, it may be useful for the radial gap between the cup-shaped guide elements and the extraction member to be constant. The material is usually broken during the loading process. It could be advantageous here to guide the shell segment initially located in the working area in such a way that an approximately funnel-shaped receiving area is formed. The longitudinal or rotary movement of the channel-shaped guide elements is preferably carried out by means of push elements, such as Hydraulic cylinders, spindles, racks or the like. In both preferred applications, the adjustment movement of the guide elements can be realized by contact switches or by optical switching devices. As a result, the stroke is set as a function of the dumping depth or the adaptation to the irregularly running work surface is achieved.

Die Steuerung der Führungselemente ist in jedem Fall dem Anwendungsfall anzupassen. Die Steuerung kann sowohl zwangs­läufig, d.h. simultan zur Höhenverstellung erfolgen oder aber auch der Höhenverstellung voreilen, um so in jedem Fall sicherzustellen, daß der Materialverlust im Ladebereich so gering wie möglich ausfällt.The control of the guide elements must be adapted to the application in each case. The control can both inevitably, i.e. take place simultaneously with the height adjustment or also lead the height adjustment in order to ensure in any case that the material loss in the loading area is as small as possible.

Die Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Fig. 1 Gewinnungsorgan mit längsbeweglichem Führungselement in der Grundstellung

  • Fig. 3 Gewinnungsorgan in angehobener Stellung mit ausfahrendem längsbeweglichem Führungselement

The invention is illustrated in the drawing and is described in more detail below. Show it
  • Fig. 1 extraction organ with longitudinally movable guide element in the basic position
  • Fig. 2 extraction organ with shell segment-shaped guide elements
  • Fig. 3 extraction organ in the raised position with extending longitudinally movable guide element
  • Fig. 4 extraction organ in the raised position with shell segments extending in the circumferential direction.

Figur 1 zeigt ein Gewinnungsorgan 1, das aus einer nicht weiter dargestellten Förderschnecke besteht, welche im äußeren Umfangsbereich mit Brechelementen versehen ist. Bedingt durch die schneckenförmige Ausbildung des unter­schlächtig arbeitenden Gewinnungsorganes 1 findet gleich­zeitig entlang der Steigungsrichtung der Schnecke ein Ladevorgang (Transport) statt. Um ein Widerlager für den Ladevorgang zu bilden, ist mindestens ein rinnenförmig ausgebildetes Führungselement außerhalb des Arbeitsbe­reiches des Gewinnungsorganes 1 vorgesehen. Diese etwa der DE-PS 33 23 395 entsprechende Einrichtung ist jedoch nur dazu in der Lage, von einem separaten Gewinnungsorgan abge­hauenes Material im Bodenbereich 3 aufzunehmen und ggf. noch zu zerkleinern. Würde die Schnecke gleichzeitig als heb- und senkbares Gewinnungsorgan 1 ausgebildet werden, so würde das gewonnene Material lediglich zu Boden fallen und müßte dann in Folgeschritten eingesammelt werden. Dies mindert jedoch den Gesamtwirkungsgrad. Um nun ein konti­nuierliches Abfördern gewonnenen Materials - unabhängig von der Arbeitshöhe des Gewinnungsorganes 1 - sicherzu­stellen, wird vorgeschlagen, daß der Bereich des rinnen­förmigen Führungselementes 2 so modifiziert wird, daß er in der Lage ist, den Bewegungen des Gewinnungsorganes 1 zu folgen.FIG. 1 shows a mining element 1, which consists of a screw conveyor, not shown, which is provided with crushing elements in the outer peripheral region. As a result of the helical design of the extraction member 1, which operates under the bottom, a loading process (transport) takes place at the same time along the slope direction of the auger. In order to form an abutment for the charging process, at least one channel-shaped guide element is provided outside the working area of the extraction member 1. However, this device, which corresponds approximately to DE-PS 33 23 395, is only able to take up material cut off from a separate extraction organ in the bottom region 3 and, if necessary, to shred it. If the screw were designed as a lifting and lowering extraction device 1 at the same time, the material obtained would simply fall to the ground and would then have to be collected in subsequent steps. However, this reduces the overall efficiency. In order to ensure a continuous removal of the material obtained - regardless of the working height of the extraction element 1 - it is proposed that the area of the channel-shaped guide element 2 be modified so that it is able to follow the movements of the extraction element 1.

Dies geschieht gemäß Figur 1 in der Weise, daß unterhalb des Führungselementes 2 mindestens eine in Vortriebsrichtung längsbewegliche Platte 4 vorgesehen ist. Die Platte 4 bzw. die Platten sind z.B. durch Rollen 5,6 längsgeführt. Figur 1 zeigt den Ausgangszustand. Das Gewinnungsorgan 1 befindet sich auf dem Boden 3 und die Platte 4 bzw. die Platten sind bündig mit dem Führungselement 2 abschließend 7 eingefahren. Die Längsbewegung der Platten 4 erfolgt durch Hydraulik­zylinder 8. Die Befestigungen 9,10 der Längsführungen 5,6 erfolgt sowohl im unteren Bereich 11 des Führungselementes 2 als auch an der Tragkonstruktion 12 eines nicht weiter dargestellten Fahrzeuges.This is done according to FIG. 1 in such a way that at least one plate 4 which is longitudinally movable in the direction of advance is provided below the guide element 2. The plate 4 or the plates are guided, for example, by rollers 5, 6. Figure 1 shows the initial state. The extraction member 1 is located on the bottom 3 and the plate 4 or the plates are flush with the guide element 2 finally 7. The longitudinal movement of the plates 4 takes place by means of hydraulic cylinders 8. The fastenings 9, 10 of the longitudinal guides 5, 6 are carried out both in the lower region 11 of the guide element 2 and on the support structure 12 of a vehicle (not shown further).

Die Ziffer 13 stellt eine Durchgangsöffnung dar, durch welche das gewonnene und geladene Material auf einen Abzugsförderer 14 aufgegeben wird. Figur 2 zeigt eine alternative Ausführungsform des Erfindungsgedankens. Gleiche Bauteile werden mit gleichen Bezugszeichen versehen. Dar­gestellt sind wieder das Gewinnungsorgan 1 sowie das Füh­rungselement 2, welches hier unter anderem als Aufnahme­teil weiterer Schalensegmente 15,16 dient. Auch hier ist eine Durchgangsöffnung 13 vorgesehen, die zum Abtransport des gewonnenen Materials auf einen Abzugsförderer 14 dient. Das Führungselement 2 ist starr ausgebildet, während die Schalensegmente 15,16 um die Horizontalachse 17 des Ge­winnungsorganes 1 schwenkbar sind. Zwischen Lagern 18 und der inneren Umfangsfläche 19 der Schalensegmente 15,16 sind Streben 20,21 angeordnet, mittels derer die Drehbe­wegung erzeugbar ist. Die Befestigung 22 der Lager 18 wird direkt an der Tragkonstruktion 23 eines nicht weiter dar­gestellten Fahrwerkes vorgenommen. Die Drehbewegung erfolgt über Hydraulikzylinder 24, die an der Strebe 21 angreifen. Die Rundung der Schalensegmente 15,16 sowie des Führungs­elementes 2 entspricht etwa der Krümmung des Gewinnungs­organes 1. Durch Betätigen des Hydraulikzlinders 24 werden diie Schalensegmente 15,16 ein- bzw. ausgefahren. Die Endbereiche der Schalensegmente 15,16 sind mit Nocken 25,26,27,28 versehen, wobei zumindest die Nocken 26 in entsprechende Führungsnuten 29 eingreifen.The number 13 represents a through-opening through which the extracted and loaded material is fed onto a discharge conveyor 14. Figure 2 shows an alternative embodiment of the inventive concept. The same components are provided with the same reference symbols. The extraction member 1 and the guide element 2 are shown again, which serves here, among other things, as a receiving part of further shell segments 15, 16. Here, too, a through opening 13 is provided, which serves for the removal of the material obtained onto a take-off conveyor 14. The guide element 2 is rigid, while the shell segments 15, 16 can be pivoted about the horizontal axis 17 of the extraction member 1. Struts 20, 21 are arranged between bearings 18 and the inner circumferential surface 19 of the shell segments 15, 16, by means of which the rotary movement can be generated. The attachment 22 of the bearing 18 is made directly on the support structure 23 of a chassis, not shown. The rotary movement takes place via hydraulic cylinders 24 which engage the strut 21. The curvature of the shell segments 15, 16 and of the guide element 2 corresponds approximately to the curvature of the extraction member 1. By actuating the hydraulic cylinder 24, the shell segments 15, 16 are retracted or extended. The end regions of the shell segments 15, 16 are provided with cams 25, 26, 27, 28, at least the cams 26 engaging in corresponding guide grooves 29.

Die Figuren 3 und 4 zeigen die Einrichtungen der Figuren 1 und 2 im Betriebszustand. Figur 3 entspricht herbei Figur 1 mit dem Unterschied, daß die Platten 4 in Vortrieb­richtung ausgefahren werden, sobald das Gewinnungsorgan 1 vom Boden abhebt und einen Schnitt in horizontaler oder vertikaler Richtung durchführt. Anaog dazu ist Figur 4 zu sehen, die der Figur 2 entspricht. Auch hier ist erkennbar, daß die Schalensegmente 15,16 in Abhängigkeit von der Arbeitshöhe des Gewinnungsorganes 1 in Umfangsrichtung zu­stellbar sind.Figures 3 and 4 show the devices of Figures 1 and 2 in the operating state. Figure 3 corresponds to Figure 1 with the difference that the plates 4 are extended in the drive direction as soon as the extraction member 1 lifts off the ground and makes a cut in the horizontal or vertical direction. Figure 4, which corresponds to Figure 2, can also be seen. It can also be seen here that the shell segments 15, 16 can be advanced in the circumferential direction depending on the working height of the extraction member 1.

In beiden Fällen wird die Verstelleinrichtung durch Kontakt­schalter oder dgl. betätigt. Dadurch wird in Abhängigkeit von der Schnittiefe T der Hub H eingestellt bzw. die An­passung an die unregelmäßig verlaufende Arbeitsfläche erreicht.In both cases, the adjustment device is actuated by contact switches or the like. As a result, the stroke H is set as a function of the depth of cut T or the adaptation to the irregularly running work surface is achieved.
