Description

Die Erfindung betrifft eine Einrichtung zum Übergeben von Haufwerk auf eine Abzugsförderer, welches durch ein vorgeschaltetes Gewinnungsorgan hereingewonnen wird insbesondere für Tagebaugeräte.The invention relates to a device for transferring bulk material to a discharge conveyor, which is won in by an upstream extraction organ, in particular for opencast mining equipment.

Vortriebsmaschinen für Bergbau- und Tunnelstrecken im Untertagebereich sind vielfältig bekannt und werden hier nur beispielhaft erwähnt (DE-PS 3323395, DE-PS 2517122).Jacking machines for mining and tunnel routes in the underground area are widely known and are only mentioned here as examples (DE-PS 3323395, DE-PS 2517122).

Die DE-PS 2517122 offenbart eine Vortriebsmaschine, die ein aus mehreren Walzen gebildetes Gewinnungsorgan aufweist, welches das Material von oben nach unten löst.DE-PS 2517122 discloses a tunneling machine which has a extraction member formed from a plurality of rollers which loosens the material from top to bottom.

Das Material fällt auf die Erde und wird durch nachgeschalteten Ladeschaufeln aufgesammelt und einem etwa mittig angeordneten Abzugsförderer (Kratzkettenförderer) zugeführt. Nachteilig ist hier neben der aufwendigen Art des Gewinnungs- und Weitertransportvorganges des Materiales, daß das Material nicht immer vollständig vom Abzugsförderer aufgenommen werden kann bzw. vorbeifällt. Dies bedingt eine zeitweise Unterbrechung des Gewinnungsvorganges, da die Vortriebsmaschine zurückfahren und das noch am Boden liegende Gut aufnehmen muß. Würde dies nicht geschehen, würde die Maschine sich immer wieder eine neue Arbeitsebene während des Vortriebes schaffen, d.h. durch das liegengebliebene Material würde sie klettern.The material falls to the ground and is collected by downstream loading shovels and fed to an extraction conveyor (scraper chain conveyor) located approximately in the middle. A disadvantage here, in addition to the complex nature of the extraction and further transport process of the material, is that the material cannot always be completely taken up by the take-off conveyor or falls by. This necessitates a temporary interruption in the extraction process, since the tunneling machine has to move back and pick up the goods that are still on the ground. If this did not happen, the machine would always create a new working level during the advance, i.e. she would climb through the broken material.

Die DE-PS 3323395 weist eine ähnliche Vortriebsmaschine auf, mit dem Unterschied, daß die Ladewerkzeuge als schwenkbare Ladeschnecken ausgebildet sind, die in ihrem rückwärtigen Bereich laderinnenbildende Schurren aufweisen. Das hereingewonnene Material wird ebenfalls einer mittig angeordneten Abfördereinrichtung zugeführt, wobei hier die gleichen Nachteile, wie vorab beschrieben, gegeben sind.DE-PS 3323395 has a similar tunneling machine, with the difference that the loading tools are designed as swiveling loading screws, which have chute-forming chutes in their rear area. The material obtained is also fed to a centrally arranged discharge device, the same disadvantages as described above being present here.

Der Erfindung liegt die Aufgabe zugrunde, eine im gattungsbildenen Teil des Hauptpatentanspruches beschriebene Einrichtung zum Übergeben von Haufwerk dahingehend zu verbessern bzw. weiterzubilden, daß eine Übergabe sowohl bei Heb- und Senkbewegungen als auch bei Querverstellungen des Gewinnungsorganes bzw. des Abzugsförderers möglich ist, ohne daß das Material durch Spalte oder dgl. auf den Erdboden fallen kann.The invention has for its object to improve or further develop a device for transferring piles described in the generic part of the main patent claim that a transfer is possible both with lifting and lowering movements and with transverse adjustments of the extraction member or the deduction conveyor, without this the material may fall to the ground through gaps or the like.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein im Übergabebereich vorgesehenes schurrenartig ausgebildetes Element, welches Bewegungen des Gewinnungsorganes bzw. des Abzugsförderers folgend, um die horizontale Achse der Umlenkrolle des Abzugsförderers drehbar sowie um eine weitere, etwa in der Mitte des Tagebaugewinnungsgerätes horizontal verlaufende Achse schwenkbar ist. Einerseits wird durch die Schurre sichergestellt, daß das hereingewonnene Material gezielt auf den nachgeschalteten Abzugsförderer übergeben wird und somit kein Material mehr vorbeifallen kann und andererseits ist durch die Beweglichkeit der Schurre in Abhängigkeit von der Bewegung des Gewinnungsorganes bzw. des Abzugsförderers gewährleistet, daß das Material in jeder Stellung übergeben werden kann.This object is achieved according to the invention by a chute-like element provided in the transfer area, which element follows movements of the extraction member or the discharge conveyor, can be rotated about the horizontal axis of the deflection roller of the discharge conveyor, and can be pivoted about a further axis which runs approximately in the middle of the opencast mining device. On the one hand, the chute ensures that the material obtained is specifically transferred to the downstream take-off conveyor and therefore no material can fall by, and on the other hand, the movability of the chute depending on the movement of the extraction organ or the take-off conveyor ensures that the material in can be handed over to any position.

Eine bevorzugte Ausführung der erfindungsgemäßen Schurre ist dadurch gekennzeichnet, daß die Schurre durch ein quer verlaufendes Winkelelement, welches an einem, mit dem Gewinnungsorgan zusammenwirkenden Führungselement für das Haufwerk befestigt ist, sowie einem zwischen dem Führungselement und dem etwa vertikal verlaufenden Schenkel des Winkelelementes angeordnetes, ebenfalls quer verlaufendes, Schild gebildet ist. Vorzugsweise wird das Schild zumindest partiell von dem etwa horizontal verlaufenden Schenkel des Winkelelementes gehäuseartig übergriffen. Das Schild ist auf der horizontalen Achse der Umlenkrolle drehbar gelagert. Da bei dieser Ausführung auch das Führungselement um diese Achse drehbar gelagert ist, werden beide Schurrenteile (Winkelelement und Schild) gemeinsam um vorgegebene Winkel gedreht.A preferred embodiment of the chute according to the invention is characterized in that the chute is also arranged by a transverse angular element which is fastened to a guide element for the pile, which cooperates with the extraction element, and by an element arranged between the guide element and the approximately vertically extending leg of the angular element transverse, shield is formed. The shield is preferably overlapped at least partially by the approximately horizontally extending leg of the angle element in a housing-like manner. The shield is rotatably mounted on the horizontal axis of the pulley. Since the guide element is also rotatably mounted about this axis in this embodiment, both running parts (angle element and shield) are rotated together by predetermined angles.

Zwangskräfte werden somit vermieden.Coercive forces are thus avoided.

Die gemeinsame Drehbewegung wird, einem weiteren Gedanken der Erfindung gemäß dadurch realisiert, daß im Bereich des Schildes eine Mitnahmevorrichtung angeordnet ist, die vorzugsweise durch ein mit vorgegebenem Radius gekrümmtes Profil gebildet ist, welches durch ein dieses umgreifendes Halteelement geführt ist.According to a further idea of the invention, the common rotary movement is realized in that a driving device is arranged in the area of the shield, which is preferably formed by a profile which is curved with a predetermined radius and is guided by a holding element encompassing it.

Bei Querverstellungen verbleibt die horizontale Achse der Umlenkrolle in ihrer Position parallel zum Erdboden und das Führungselement wird um einen vorgegebenen Winkel in der einen oder anderen Richtung quergestellt. Damit auch in dieser Stellung das Schild um die Achse gedreht werden kann, ist das gekrümmte Profil dergestalt gebogen, daß ein Radius um die Achsmitte der in der Tagebaugerätemitte angeordneten Achse gegeben ist.In the case of transverse adjustments, the horizontal axis of the deflection roller remains in its position parallel to the ground and the guide element is transversed by a predetermined angle in one direction or the other. So that the shield can also be rotated about the axis in this position, the curved profile is bent in such a way that there is a radius around the center of the axis of the axis arranged in the center of the surface mining equipment.

Darüberhinaus wird zur Erreichung der erforderlichen Freigängigkeit im Schurrenbereich vorgeschlagen, daß der dem Abzugsförderer zugewandte, ewta vertikal verlaufende Schenkel des Winkelprofiles kurvenförmig oder abgeschrägt ausgebildet ist, wobei die größte Erstreckung in seinem mittleren Bereich und die geringsten Erstreckungen in seinen äußeren Bereichen vorgesehen sind. Sofern dies gewünscht wird, besteht darüberhinaus die Möglichkeit im Bereich des so profilierten Vertikalschenkels ein elastisches Profil vorzusehen, welches, ggf. unter Vorspannung, an der Oberfläche des Abzugsförderers anliegt. Hier wird ein zusätzlicher, den Spalt reduzierender bzw. minimierender Dichteffekt erzielt, der Haufwerk geringerer Körnung vor dem Vorbeifallen bewahrt bzw. einer eventuellen Verstopfung des Spaltes zwischen Vertikalschenkel und Scheibe entgegenwirkt.In addition, in order to achieve the necessary freedom of movement in the chute area, it is proposed that the ewta vertically extending leg of the angle profile facing the discharge conveyor be curved or beveled, the greatest extent being provided in its central area and the least extent in its outer areas. If this is desired, there is also the possibility in the area of the vertical leg profiled in this way to provide an elastic profile which, if appropriate with prestress, bears against the surface of the discharge conveyor. Here, an additional sealing effect that reduces or minimizes the gap is achieved, the pile of smaller grain size is prevented from falling by, or counteracts a possible blockage of the gap between the vertical leg and the disc.

Als weitere Maßnahme zur Erzielung einer guten Freigängigkeit wird vorgeschlagen, daß das im wesentlichen vertikal verlaufende Schild in seinem, dem etwa horizontal verlaufenden Schenkel des Winkelprofiles zugewandten Bereich kurvenförmig oder abgeschrägt ausgebildet ist, wobei die größten Erstreckungen in seinen äußeren Bereichen und die kleinste Erstreckung in seinem mittleren Bereich vorgesehen sind.As a further measure to achieve good freedom of movement, it is proposed that the substantially vertically extending shield is curved or beveled in its region facing the approximately horizontally extending leg of the angle profile, the largest extensions in its outer regions and the smallest extension in its middle area are provided.

Durch die vorgeschlagenen Maßnahmen erfolgt der Übergang vom Führungselement zum Abzugsförderer bzw. zur Umlenktrommel dergestalt, daß sich an der Übergabestelle kein Spalt bilden kann, durch den Material zwischen der Schurre und der Umlenktrommel auf den Erdboden fallen kann, und zwar unabhängig von der Stellung des Gewinnungsorganes. Bevorzugte Anwendungsgebiete der Erfindung sind bei solchen Tagebaugeräten zu sehen, die als Gewinnungsorgan quer vor dem Gerät liegende Schnecken aufweisen.Due to the proposed measures, the transition from the guide element to the discharge conveyor or to the deflection drum takes place in such a way that no gap can form at the transfer point through which material between the chute and the deflection drum can fall to the ground, regardless of the position of the extraction member . Preferred areas of application of the invention are to be seen in those open-cast mining devices which have screws lying transversely in front of the device as the extraction organ.

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

  • Fig. 1 Teilansicht eines Tagebaugewinnungsgerätes mit vorgeschaltetem Gewinnungsorgan
  • Fig. 2 Ausschnitt des Übergabebereiches vom Gewinnungsorgan auf einen Abzugsförderer
  • Fig. 3 Schnittdarstellung der Schurre gem. Fig. 2 (Schnitt II-II)
  • Fig. 4 Schnittdarstellung des Winkelprofiles gem. Fig. 3 (Schnitt I-I)
The invention is illustrated in the drawing and is described as follows. Show it:
  • Fig. 1 partial view of an open pit mining device with upstream mining organ
  • Fig. 2 section of the transfer area from the extraction organ to a deduction conveyor
  • Fig. 3 sectional view of the chute acc. Fig. 2 (section II-II)
  • Fig. 4 sectional view of the angle profile acc. 3 (section II)

Figur 1 zeigt die Teilansicht eines Tagebaugewinnungsgerätes. Lediglich angedeutet ist das Gewinnungsorgan 1, welches einem Fahrwerk 2 vorgeschaltet ist. Das Gewinnungsorgan ist als Schnecke ausgebildet, die das Material 3 in unterschlächtiger Arbeitsweise hereingewinnt.Figure 1 shows the partial view of an open pit mining device. The extraction element 1, which is connected upstream of a chassis 2, is only indicated. The extraction organ is designed as a screw that extracts the material 3 in a subtle manner.

Das Material 3 wird zwischen der Schnecke 1 und einem dahinter angeordneten Führungselement 4 von beiden Seiten ausgehend zur Mitte transportiert. Dort staut es sich und wird durch eine oberhalb des Führungselementes 4 vorgesehene Öffnung 5 einem nachgeschalteten Abzugsförderer 6 übergeben.The material 3 is transported between the screw 1 and a guide element 4 arranged behind it, starting from both sides towards the center. There it builds up and is passed through an opening 5 provided above the guide element 4 to a downstream discharge conveyor 6.

Im Übergabebereich ist ein in den Figuren 2 - 4 näher beschriebenes schurrenartig ausgebildetes Element 7 vorgesehen, welches, Bewegungen des Gewinnungsorganes 1 folgend, um die horizontale Achse 8 der Umlenkrolle 9 des Abzugsförderers drehbar sowie um eine weitere, etwa in der Mitte des Tagebaugewinnungsgerätes horizontal verlaufende Achse 20 schwenkbar ist. Das schurrenförmige Element 7 ist zweiteilig ausgebildet. Es besteht aus einem quer verlaufenden Winkelelement 10, welches mit seinem horizontal verlaufenden Schenkel 11 am Führungselement 4 befestigt ist. Ferner ist ein etwa vertikal sich erstreckendes Schild 12 vorgesehen, welches zwischen dem vertikal verlaufenden Schenkel 13 des Winkelelementes 10 und dem Führungselement 4 angeordnet ist. Das Material 3 gelangt in Pfeilrichtung auf den Abzugsförderer 6. Infolge der im Bereich der Umlenktrommel 9 gebildeten Barriere kann hier kein Spalt entstehen, durch welchen hereingenommenes Material 3 wieder auf den Erdboden 14 fallen könnte. Somit ist ein kontinuierlicher Gewinnungs- und Transportvorgang gewährleistet, wobei das Tagebaugewinnungsgerät auf einem selbst geschaffenen Planum verfahren kann, ohne daß die Gefahr des Kletterns gegeben ist. Sowohl das Führungselement 4 als auch das Schild 12 sind um die horizontale Achse 8 der Umlenkrolle 9 drehbar gelagert, so daß bei Bewegungen um diese Achse (Winkelα, β) eine gemeinsame simultane Verlagerung stattfindet. Dies wird dadurch erreicht, daß eine Mitnahmevorrichtung 15 vorgesehen ist, die aus einem gebogenen Profil 16 mit einem vorgegebenen Radius R gebildet ist, welches zwischen Halteelemente 17,18 führbar ist.Provided in the transfer area is a chute-like element 7, which is described in more detail in FIGS Axis 20 is pivotable. The chute-shaped element 7 is formed in two parts. It consists of a transverse angle element 10 which is fastened to the guide element 4 with its horizontally extending leg 11. Furthermore, an approximately vertically extending shield 12 is provided, which is arranged between the vertically extending leg 13 of the angle element 10 and the guide element 4. The material 3 reaches the discharge conveyor 6 in the direction of the arrow. As a result of the barrier formed in the region of the deflection drum 9, no gap can arise here, through which the material 3 taken in could fall again onto the ground 14. This ensures a continuous extraction and transport process, with the mining equipment being able to move on a self-made subgrade without the risk of climbing. Both the guide element 4 and the shield 12 are rotatably mounted about the horizontal axis 8 of the deflection roller 9, so that a common simultaneous displacement takes place during movements about this axis (angle α, β). This is achieved in that a driving device 15 is provided, which is formed from a curved profile 16 with a predetermined radius R, which can be guided between holding elements 17, 18.

Bei Querverstellung verbleibt die Achse 8 in ihrer Position parallel zum Erdboden 14 und das Führungselement 4 wird um den Winkelγ quergestellt. Damit auch in dieser Stellung das Schild 12 um die Achse 8 gedreht werden kann, ist das Profil vorzugsweise mit einem Radius R um die Achse 20 (Fig. 1), d.h. deren Achsmitte gebogen.In the case of transverse adjustment, the axis 8 remains in its position parallel to the ground 14 and the guide element 4 is transversed by the angle γ. So that the shield 12 can also be rotated about the axis 8 in this position, the profile is preferably with a radius R about the axis 20 (FIG. 1), i.e. the center of its axis curved.

Zur Erreichung der erforderlichen Freigängigkeit sind der vertikal verlaufende Schenkel 13 des Winkelprofiles 10 sowie das Schild 12 in seinem, dem horizontal verlaufenden Schenkel 11 des Winkelprofiles 10 zugwandten Bereich kurvenförmig ausgebildet 19,21. Die größten Abmessungen a des Schildes 12 befinden sich in seinen beiden äußeren Bereichen, während die größte Abmessung b des Winkelprofiles 10 bzw. dessen Vertikalschenkels 13 in der Mitte vorgesehen sind. Um eine bessere Anpassung an den Abzugsförderer 6 zu erzielen, kann der vertikale Schenkel 13 des Winkelprofiles 10 ggf. noch mit einem elastisch verformbaren Element (nicht dargestellt) versehen werden.To achieve the required freedom of movement, the vertically extending leg 13 of the angle profile 10 and the shield 12 are curved 19, 21 in its area facing the horizontally extending leg 11 of the angle profile 10. The largest dimensions a of the shield 12 are in its two outer areas, while the largest dimension b of the angle profile 10 or its vertical leg 13 are provided in the middle. In order to achieve a better adaptation to the discharge conveyor 6, the vertical leg 13 of the angle profile 10 can optionally also be provided with an elastically deformable element (not shown).
