Description

Die Erfindung betrifft eine Übergabestation im Übergangsbereich zwischen einem Strebförderer und einem Strecken- oder Übergabeförderer im Bergbau im Bereich eines Antriebs für den Strebförderer, wobei der Strecken- oder Übergabeförderer relativ zum Strebförderer begrenzt schwenkbeweglich an diesen angebunden ist.The invention relates to a transfer station in the transition region between a longwall conveyor and a route or transfer conveyor in mining in the field of a drive for the longwall conveyor, wherein the route or transfer conveyor is limited pivotally connected to this relative to the longwall conveyor.

Bei der Gewinnung von Kohle, Erz oder anderen Gewinnungsprodukten im Langfrontbau wird das von der Gewinnungsmaschine an der Ortbrust im Streb gelöste Haufwerk einem Strebförderer - im Allgemeinem einem Kratzerkettenförderer-übergeben und von diesem durch den Streb bis zum Strebende transportiert, wo der Streb in die etwa rechtwinklig zu diesem aufgefahrene Strecke mündet. Das Haufwerk wird dort einem in der Strecke angeordneten Streckenförderer übergeben, entweder unmittelbar oder mit Hilfe eines kurzen Übergabeförderers, der parallel zum Strecken-förderer seitlich neben diesem verläuft und der das Vorrücken der Gewinnungs- und Fördereinrichtungen im Streb beim fortschreitenden Abbau jedenfalls über eine begrenzte Länge mitmachen kann. Da sich die Winkelstellung des Strebförderers relativ zu dem in der Strecke angeordneten Strecken- oder Übergabeförderer infolge veränderlicher Abbaubedingungen ebenfalls verändern kann, ist der Strecken- oder Übergabeförderer relativ zum Strebförderer um eine etwa senkrecht zum Liegenden angeordnete Achse begrenzt schwenkbeweglich an diesem angebunden. Dies wird bei einem von der Anmelderin realisierten Übergang durch ein als Drehgestell konzipiertes Auflager für die endseitige (Haupt-) Antriebsstation des Strebförderers realisiert, wobei sich das Unterteil des Drehgestelles auf dem Liegenden in der Strecke abstützt und einen seitlichen Anschluss für den Übergabe- oder Streckenförderer aufweist, der sich dann in dem am Drehgestell montierten Zustand unterhalb des Abwurfbereiches des Strebförderers befindet.In the extraction of coal, ore or other extraction products in Langfrontbau the loosened by the mining machine at the Ortbrust in the longwall heap a Strebförderer - handed over a scraper chain conveyor in general and transported by this through the longwall to the aspirant, where the longwall in the about opens at right angles to this uprivered route. The debris is there passed to a distance conveyor arranged in the track, either directly or with the aid of a short transfer conveyor, which runs parallel to the conveyor laterally next to this and the advancement of the extraction and handling facilities in the longwall as progressing degradation in any case over a limited length can join. Since the angular position of the longwall conveyor relative to the distance or transfer conveyor arranged in the route can also change as a result of variable mining conditions, the route or transfer conveyor is limited pivotally connected to this relative to the longwall conveyor about an axis arranged approximately perpendicular to the horizontal. This is realized in a realized by the applicant transition through a designed as a bogie support for the end (main) drive station of the longwall conveyor, wherein the lower part of the bogie is supported on the footwall in the route and a lateral connection for the transfer or track conveyor has, which is then in the bogie mounted state below the discharge area of the longwall conveyor.

Die bekannte Lösung hat sich zwar in der Praxis bewährt, ist jedoch vergleichsweise aufwendig und teuer, da mit dem Drehgestell die großen Auflagerkräfte im Bereich des (Haupt-) Antriebs des Strebförderers aufgenommen und in das Liegende in der Strecke abgesetzt werden müssen, worunter die Schwenkbeweglichkeit zwischen den beiden Förderern nicht beeinträchtigt werden darf. Entsprechend groß muss das Axiallager dimensioniert sein, um die Drehbeweglichkeit des Strebfördererantriebs relativ zum Unterteil des Drehgestells zu gewährleisten.Although the known solution has proven itself in practice, it is comparatively complicated and expensive since the large bearing forces in the area of the (main) drive of the longwall conveyor have to be absorbed by the bogie and placed in the horizontal position, including the pivoting mobility between the two sponsors must not be affected. Correspondingly large, the axial bearing must be dimensioned to ensure the rotational mobility of the longwall conveyor drive relative to the lower part of the bogie.

Aus der DE 35 21 793 A1 ist eine Übergabestation für den Streb-Streckenübergang bekannt, bei welcher die Antriebsstation des Strebförderers in der Strecke auf einer Konsole über ein vertikales Drehlager abgestützt ist.From the DE 35 21 793 A1 For example, a transfer station for the longwall crossing is known, in which the drive station of the longwall conveyor is supported in the track on a console via a vertical pivot bearing.

Aus der DE 36 07 212 A1 ist es für den Streb-Streckenübergang bekannt, zwischen der Antriebsstation des Strebförderers und einem Streckenförderer einen Feingutförderer anzuordnen, mit dem in derselben Richtung wie mit dem Strebförderer gefördert wird und der sich über einen aufragenden Schwenkzapfen schwenkbeweglich auf einem Unterbau abstützt, wobei der Unterbau mit dem Streckenförderer verschieblich gekoppelt ist.From the DE 36 07 212 A1 it is known for the long-distance crossing, between the drive station of the longwall conveyor and a track conveyor to arrange a fine material conveyor, which is supported in the same direction as with the longwall conveyor and which is supported on an upright pivot pivotally mounted on a substructure, the substructure with the Track conveyor is slidably coupled.

Aus der DE 26 59 855 A1 ist eine Übergabestation von einem Strebkettenförderer auf einen Streckenkettenförderer bekannt, bei welcher zur besseren räumlichen Anpassungsfähigkeit der Übergabestation im Kreuzpunkt von Strecke und Streb ein Kugelgelenk angeordnet ist.From the DE 26 59 855 A1 is a transfer station from a long-chain conveyor on a line chain conveyor known in which a ball joint is arranged for better spatial adaptability of the transfer station in the cross point of distance and longwall.

Aufgabe der Erfindung ist es, eine Übergabestation der eingangs definierten Art zu schaffen, die im Vergleich zu der im Stand der Technik realisierten Lösung einfacher und kostengünstiger ist.The object of the invention is to provide a transfer station of the type defined, which is easier and less expensive compared to the realized in the prior art solution.

Diese Aufgabe wird mit der Erfindung dadurch gelöst, dass an einem Unterbau des Antriebs für den Strebförderer eine Aufnahmeplatte angeordnet ist, die mit einer Lageraufnahme versehen ist, in der ein Anschlussrinnenelement des Streckenförderers um eine von der Lageraufnahme definierte Schwenkachse relativ zum Strebförderer bzw. dessen Antrieb schwenkbeweglich gelagert ist.This object is achieved with the invention in that on a substructure of the Drive for the longwall conveyor a receiving plate is arranged, which is provided with a bearing receptacle in which a connection trough element of the distance conveyor is mounted pivotably about a pivot axis defined by the bearing receiving pivot axis relative to the longwall conveyor or its drive.

Anders als bei dem zuvor beschriebenen Stand der Technik wird bei der Erfindung also nicht der Strebfördererantrieb über ein Drehgestell/ einen Unterbau um eine im Wesentlichen lotrechte Achse schwenkbeweglich auf dem Liegenden der Strecke aufgestützt, sondern die Schwenkbeweglichkeit des Strecken- oder Übergabeförderers relativ zum Strebförderer wird durch ein spezielles Anschlussrinnenelement erreicht, das schwenkbeweglich in der Lageraufnahme der Aufnahmeplatte aufgenommen ist, die seitlich an dem den Antrieb des Strebförderers auflagernden Unterbau angeordnet ist. Die schwenkbewegliche Lagerung des besonderen Anschlussrinnenelementes in der Lageraufnahme der Aufnahmeplatte ist erheblich einfacher und kostengünstiger zu realisieren, da die dabei zu übertragenden Lagerkräfte, die im Wesentlichen aus dem Gewicht des Anschlussrinnenelementes und dem im Bereich des Anschlussrinnenelementes geförderten Hauptwerkes resultiert, erheblich geringer ist als die Last, die von dem Strebfördererantrieb resultiert und von dessen Unterbau in das Liegende abgesetzt werden muss.Unlike the prior art described above, in the invention, therefore, not the Strebfördererantrieb on a bogie / a substructure about a substantially vertical axis pivotally supported on the footwall of the route, but the pivoting mobility of the route or transfer conveyor relative to the longwall conveyor is through reaches a special terminal channel element, which is pivotally received in the bearing receptacle of the receiving plate, which is arranged on the side of the drive of the longwall supporting the substructure. The pivotable mounting of the special connection trough element in the bearing receptacle of the receiving plate is considerably simpler and less expensive to implement, since the bearing forces to be transmitted, which essentially results from the weight of the trough element and the main work conveyed in the region of the trough element, is considerably lower than the load , which results from the longwall conveyor drive and must be discontinued from the substructure in the lying.

Vorzugsweise wird die Lageraufnahme im Wesentlichen von einer in der Aufnahmeplatte ausgebildeten Lagerbohrung gebildet, in die ein am Anschlussrinnenelement unterseitig angeordneter Lagerzapfen einfasst. Zweckmäßig wird die Anordnung so getroffen, dass das an der Aufnahmeplatte gelagerte Anschlussrinnenelement gegen ein Ausheben des Lagerzapfens aus der Lagerbohrung gesichert ist, was in vorteilhafter Weiterbildung der Erfindung beispielsweise dadurch geschehen kann, dass das Anschlussrinnenelement mit mindestens einem seitlich bzw. radial vom Lagerzapfen vorspringenden Haltekragen versehen ist, der von einer an der Aufnahmeplatte vorzugsweise lösbar angeordneten Riegelleiste mit Spiel übergriffen wird. Auf diese Weise ist das Anschlussrinnenelement gegen Ausheben aus der Lagerbohrung formschlüssig gesichert, wobei die Riegelleisten infolge der vorgesehenen Spielfreiheit erst dann in Kontakt mit dem Haltekragen kommen, wenn sich das Anschlussrinnenelement ein Stück weit aus der Lagerbohrung emporhebt und dann eine Weiterbewegung in Axialrichtung des Lagerzapfens unterbinden. Im Regelfall liegt die Riegelleiste ein Stück oberhalb des Haltekragens, so dass es zu keiner Beeinflussung der Drehbeweglichkeit zwischen Anschlussrinnenelement und Aufnahmeplatte infolge von Reibung zwischen den Riegelleisten und dem Haltekragen kommt. Weiter vorteilhaft ist es in diesem Zusammenhang, wenn der mindestens eine Haltekragen einen vorzugweise mittleren Scheitel aufweist, von dem aus er beidseitig in Richtung auf die Enden des Anschlussrinnenelementes schräg nach innen zuläuft, der Haltekragen also nach Art einer stumpfwinkligen Pfeilspitze gestaltet ist. Diese Anordnung gewährleistet zuverlässig die Dreh- bzw. Schwenkbeweglichkeit des Anschlussrinnenelementes in der Aufnahmeplatte.Preferably, the bearing receptacle is essentially formed by a bearing bore formed in the receiving plate, into which a bearing pin arranged on the lower side of the mounting groove element engages. Suitably, the arrangement is made such that the mounted on the receiving plate connection trough element is secured against lifting of the journal from the bearing bore, which can be done in an advantageous embodiment of the invention, for example, that the terminal trough element with at least one laterally or radially from the journal projecting retaining collar is provided, which is overlapped by a preferably releasably arranged on the mounting plate locking bar with play. In this way, the connection gutter element is secured against lifting out of the bearing bore form-fitting, wherein the locking strips come as a result of the freedom from play only in contact with the retaining collar when the Anschlußrinnenelement lifted a bit far out of the bearing bore and then prevent further movement in the axial direction of the journal , As a rule, the locking bar is located a bit above the retaining collar, so that there is no influence on the rotational mobility between the connecting channel element and the receiving plate as a result of friction between the tie-bars and the retaining collar. It is also advantageous in this context if the at least one retaining collar has a preferably central vertex, from which it tapers inwardly on both sides in the direction of the ends of the connection trough element, ie the retaining collar designed in the manner of an obtuse arrowhead. This arrangement reliably ensures the rotational or pivoting mobility of the connection trough element in the receiving plate.

Es ist vorteilhaft, wenn die Riegelleiste an der Aufnahmeplatte lösbar befestigt ist, was vorzugsweise mittels an Schlüssellochaufnahmen an der Aufnahmeplatte anschlagbaren Befestigungsschrauben oder -bolzen geschehen kann, welche die Riegelleiste durchsetzen und diese mittels Schließmuttern gegen die Aufnahmeplatten klemmen. Durch diese Anordnung kann die Riegelleiste einfach und schnell demontiert werden, um beispielsweise für Wartungs- oder Reparaturzwecke das Anschlussrinnenelement von der Aufnahmeplatte abzubauen und durch ein Austauschteil zu ersetzen.It is advantageous if the bolt bar is releasably secured to the receiving plate, which can preferably be done by means of attachable to keyhole recordings on the receiving plate mounting bolts or bolts, which enforce the bolt bar and clamp them by means of lock nuts against the mounting plates. By this arrangement, the bolt bar can be easily and quickly disassembled to reduce, for example, for maintenance or repair purposes, the gutter element of the receiving plate and replaced by a replacement part.

Vorteilhaft ist es auch, wenn das Anschlussrinnenelement unterseitig mit zum Lagerzapfen beabstandet angeordneten Auflager-Gleitelementen versehen ist, mit denen das Anschlussrinnenelement auf der Aufnahmeplatte gleitbeweglich aufliegt. Bei diesen Auflager-Gleitelementen kann es sich insbesondere um als quer zur Längsrichtung des Strecken- oder Übergabeförderers verlaufenden Auflagerleisten handeln. Mit den Auflager-Gleitelementen wird die Schwenkbeweglichkeit zwischen Anschlussrinnenelement und Aufnahmeplatte zusätzlich begünstigt.It is also advantageous if the connection trough element is provided on the underside with bearing slides which are arranged at a distance from the bearing journal and with which the trough element rests in a sliding manner on the receiving plate. In particular, these support slide elements can be support strips running transversely to the longitudinal direction of the transfer conveyor or transfer conveyor. With the support slide elements, the pivoting mobility between the connecting channel element and receiving plate is additionally favored.

In besonders vorteilhafter Weiterbildung der Erfindung ist das Anschlussrinnenelement mit einer einen Zugang zum Untertrum des Strecken- oder Übergabeförderers schaffenden Revisionsöffnung versehen, die mittels einer von einer Rinnenseite einschiebbaren Abdeckplatte verschließbar ist. Dabei ist die Abdeckplatte vorzugsweise seitlich in im Schnitt vorzugsweise etwa V-förmigen Führungsschienen geführt, in denen sie beim Ein- oder Ausschieben der Abdeckplatte zuverlässig gleiten kann.In a particularly advantageous embodiment of the invention, the connection channel element is provided with an access to the lower run of the route or transfer conveyor creating inspection opening which can be closed by means of a retractable from a gutter cover plate. In this case, the cover plate is preferably guided laterally in the section preferably approximately V-shaped guide rails, in which they can slide reliably when inserting or expelling the cover plate.

Die Abdeckplatte ragt vorteilhafterweise im am Anschlussrinnenelement montierten Zustand beidseitig über seitliche Begrenzungsprofile des Rinnenelementes vor und ist an den vorragenden Bereichen mit Anschlagöffnungen versehen, und an den Begrenzungsprofilen sind vorzugsweise seitlich vorragende, mit den Anschlagöffnungen fluchtende Arretierösen angeordnet, wobei zur Arretierung Befestigungsbolzen durch die Anschlagöffnungen und die Arretierösen steckbar und in der eingesteckten Lage verriegelbar sind. Auf diese Weise lässt sich die Abdeckplatte am Anschlussrinnenelement einfach, schnell und zuverlässig festlegen.The cover plate protrudes advantageously in mounted on the connection channel element on both sides over lateral boundary profiles of the channel element and is provided at the projecting areas with stop openings, and the boundary profiles are preferably laterally projecting, aligned with the stop openings Arretierösen arranged, with locking pins for locking through the stop openings and the locking eyelets are pluggable and locked in the inserted position. In this way, the cover plate can be easily, quickly and reliably set on the connection channel element.

Um dem Anschlussrinnenelement eine besonders große Steifigkeit und Haltbarkeit zu verschaffen, kann es mit an seinen seitlichen Begrenzungsprofilen angeschweißten Versteifungsrippen versteift sein, wobei dann die Riegelleisten im Bereich der Versteifungsrippen mit Aussparungen versehen sein können, deren Weite so bemessen ist, dass die in sie einfassenden Versteifungsrippen die Schwenkbeweglichkeit des Anschlussrinnenelementes relativ zur Aufnahmeplatte im vorgesehenen Schwenkbereich von vorzugsweise bis zu ± 5° nicht behindern.In order to provide the connection trough element a particularly high rigidity and durability, it can be stiffened with welded to its lateral boundary profiles stiffening ribs, in which case the tie bars can be provided in the region of the stiffening ribs with recesses whose width is such that the stiffening ribs enclosing them the pivoting mobility of the connection trough element relative to the receiving plate in the intended pivoting range of preferably up to ± 5 ° do not hinder.

Diese und weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung und der Zeichnung, worin eine bevorzugte Ausführungsform der Erfindung anhand eines Beispiels näher erläutert ist. Es zeigt:

  • Fig. 1 einen Übergang zwischen einem Strebförderer und einem Streckenförderer im untertägigen Bergbau in einer Seitenansicht;

These and other features and advantages of the invention will become apparent from the following description and the drawings, wherein a preferred embodiment of the invention by way of example is explained in more detail. It shows:
  • Fig. 1 a transition between a longwall conveyor and a track conveyor in underground mining in a side view;
  • Fig. 2 a part of the substructure of the main drive of the longwall conveyor according to Fig. 1 in an enlarged view;
  • Fig. 3 the substructure after Fig. 2 in a plan view;
  • Fig. 4 the object of Fig. 2 and 3 in a perspective, partially exploded view obliquely from below; and
  • Fig. 5 a representation of a detail V after Fig. 2 on average.

Fig. 1 zeigt eine in ihrer Gesamtheit mit 10 bezeichnete Übergabestation im Übergangsbereich zwischen einem in einem Abbaustreb 11 im untertägigen Bergbau angeordneten Strebförderer 12 und einem Streckenförderer 13, der auf dem Liegenden 14 einer Strecke 15 angeordnet ist, von welcher der Abbaustreb 11 abgeht. Fig. 1 shows a designated in their entirety by 10 transfer station in the transition region between a arranged in a quarry 11 in underground mining longwall conveyor 12 and a track conveyor 13, which is located on the foot 14 of a route 15 from which the mining route 11 goes off.

Die Übergabestation 10 weist einen Unterbau 16 auf, der den Hauptantrieb 17 des Strebförderers unterstützt. Soweit bis hierher beschrieben, entspricht die Übergabestation üblichen Anordnungen, wie sie im untertägigen Bergbau beispielsweise in Kohlegewinnungsbetrieben vielfältig im Einsatz sind.The transfer station 10 has a base 16, which supports the main drive 17 of the longwall conveyor. As far as described so far, the transfer station corresponds to the usual arrangements, as they are used in underground mining, for example, in coal mining operations varied.

Man erkennt aus den weiteren Figuren, dass der Streckenförderer 13 relativ zum Strebförderer 12 an diesen begrenzt schwenkbeweglich angebunden ist. Hierzu ist an dem Unterbau 16 an dessen zum Streckenförderer hin weisender Außenseite 18 eine auf dem Liegenden 14 aufliegende Aufnahmeplatte 19 fest angebunden, wobei die Aufnahmeplatte 19 einen zentralen, kreisförmigen Ausschnitt 20 hat, der eine Lageraufnahme 21 für ein spezielles Anschlussrinnenelement 22 des Streckenförderers 13 bildet. Dieses Anschlussrinnenelement 22, an dem dann übliche Rinnenschüsse (nicht dargestellt) des in an sich bekannter Weise als Kettenkratzerförderers ausgebildeten Streckenförderers mit üblichen Knebelverbindungen 23 angeschlossen werden, hat an seiner Unterseite 24 einen an die Größe der Lagerbohrung 20 angepassten Lagerzapfen 25, der bei dem dargestellten Ausführungsbeispiel ringförmig ausgestaltet ist und mit geringem Spiel in die Lageraufnahme 21 einfasst, wie dies insbesondere in den Fig. 2 und 5 gut erkennbar ist. Diese Ausgestaltung erlaubt es, dass sich das Anschlussrinnenelement um die im Wesentlichen lotrecht zum Liegenden 14 ausgerichtete Drehachse 26 der Lageraufnahme ausreichend weit nach links oder rechts verschwenken kann, um Abweichungen von einer rechtwinkligen Anordnung der beiden Förderer zueinander auszugleichen. Gleichzeitig gewährleistet der formschlüssige Eingriff des Lagerzapfens an der Unterseite des Anschlussrinnenelementes in die in der Aufnahmeplatte vorgesehene Lageraufnahme, dass Kräfte/Bewegungen in einer Richtung rechtwinklig zur Drehachse von der Anordnung übertragen werden können.It can be seen from the other figures that the track conveyor 13 is connected to this limited pivotally movable relative to the longwall conveyor 12. For this purpose, a receiving plate 19 resting on the lying 14 receiving plate 19 is firmly attached to the base 16 at the outer side facing the track conveyor 14, wherein the receiving plate 19 has a central, circular cutout 20 which forms a bearing receptacle 21 for a special connection trough element 22 of the track conveyor 13 , This connection trough element 22, to which then usual gutter shots (not shown) of the trained in a known manner as a chain scraper conveyor track conveyor are connected with conventional toggle connections 23, has on its underside 24 adapted to the size of the bearing bore 20 bearing pin 25, in the illustrated Embodiment is configured annular and with a small clearance in the bearing seat 21 engages, as in particular in the Fig. 2 and 5 is clearly recognizable. This embodiment makes it possible for the connection channel element to be able to pivot sufficiently far to the left or right about the rotational axis 26 of the bearing receptacle that is oriented substantially perpendicular to the horizontal 14 in order to compensate deviations from a rectangular arrangement of the two conveyors relative to one another. At the same time, the positive locking ensures Engaging the bearing pin on the underside of the connection channel element in the provided in the receiving plate bearing receptacle that forces / movements can be transmitted in a direction perpendicular to the axis of rotation of the assembly.

Damit es nicht zu einem unbeabsichtigten Ausheben des Lagerzapfens 25 aus der Lagerbohrung 20 kommt, ist das Anschlussrinnenelement 22 mit einer Aushebesicherung in seiner Lage gesichert. Die Aushebesicherung wird im Wesentlichen von zwei an den Längsseiten des Anschlussrinnenelementes 22 seitlich radial vom Lagerzapfen vorspringenden Haltekragen 27 gebildet, die von im Querschnitt etwa L-förmigen Riegelleisten 28 übergriffen werden. Die Riegelleisten 28 stützen sich mit ihrem einen, aufrechten Schenkel 29 auf der Oberseite der Aufnahmeplatte 19 ab und sind gegen diese mit Befestigungsschrauben 30 angeschlagen, die durch Bohrungen 31 in den aufrechten Schenkeln 29 der Riegelleisten gesteckt und oberseitig mit Muttern 32 gesichert sind. Um die Befestigungsschrauben bei Bedarf leicht austauschen zu können, sind für sie in der Aufnahmeplatte schlüssellochförmige Aufnahmeöffnungen 33 vorgesehen, so dass die Befestigungsschrauben von oben mit ihrem Schraubenkopf durch den größeren, zylindrischen Teil der Schlüssellochaufnahme eingesteckt und dann seitlich verschoben werden können, so dass der Schraubenkopf in den schmaleren Bereich der Schlüssellochaufnahme gelangt und dort ein Widerlager findet.So that it does not come to an unintentional lifting of the bearing pin 25 from the bearing bore 20, the connection channel element 22 is secured with a lifting protection in its position. The lift-off is essentially formed by two on the longitudinal sides of the connection channel element 22 laterally projecting radially from the bearing pin retaining collar 27, which are overlapped by approximately cross-sectionally L-shaped locking strips 28. The tie bars 28 are supported with their one, upright leg 29 on the top of the receiving plate 19 and are struck against this with fastening screws 30 which are inserted through holes 31 in the upright legs 29 of the tie bars and secured on the top side with nuts 32. In order to easily replace the mounting screws when needed, keyhole-shaped receiving openings 33 are provided for them in the receiving plate, so that the mounting screws can be inserted from above with her screw head through the larger, cylindrical part of the keyhole holder and then moved laterally, so that the screw head enters the narrower area of the keyhole receptacle and finds an abutment there.

Man erkennt insbesondere in der Fig. 4, dass die seitlich an dem Anschlussrinnenelement ausgebildeten Haltekragen 27 einen mittleren Scheitel 34 haben, von dem aus sie zu den beiden Enden des Anschlussrinnenelementes hin schräg nach innen zulaufen, so dass eine Schwenkbeweglichkeit im erforderlichen Maße - etwa ± 5 % zur Längsrichtung des Strebförderers - gewährleistet ist, bis die Haltekragen in Anlage mit dem aufrechten Schenkel 29 der Riegelleisten 28 kommen können.One recognizes in particular in the Fig. 4 in that the retaining collars 27 formed laterally on the connecting channel element have a central vertex 34, from which they taper inwards towards the two ends of the connecting channel element, so that pivoting mobility is ensured to the required extent - for example ± 5% relative to the longitudinal direction of the longwall conveyor is until the retaining collar can come into contact with the upright leg 29 of the tie bars 28.

Man kann in den Fig. 4 und 5 weiterhin gut erkennen, dass das Anschlussrinnenelement 22 beidseitig über seitliche Begrenzungsprofile 35 verfügt, an deren Außenseiten Versteifungsrippen 36 zur Versteifung des Anschlussrinnenelementes angeschweißt sind. Um einerseits die Schwenkbeweglichkeit des Anschlussrinnenelementes nicht einzuschränken, andererseits eine bestmögliche Versteifung durch die Rippen 36 zu erhalten, sind die horizontalen Schenkel 37 der Riegelleisten 28 im Bereich der Versteifungsrippen 36 mit Aussparungen 38 versehen, deren Weite in Längsrichtung des Streckenförderers so bemessen sind, dass die in sie einfassenden Versteifungsrippen 36 die Schwenkbeweglichkeit des Anschlussrinnenelementes 22 relativ zur Aufnahmeplatte 19 im vorgesehenen Schwenkbereich nicht behindeni.You can go to the Fig. 4 and 5 furthermore, that the connecting gutter element 22 has on both sides lateral limiting profiles 35, on the outer sides of which reinforcing ribs 36 are welded to stiffen the connecting gutter element. In order not to restrict the pivoting mobility of the connection channel element on the one hand, on the other hand to obtain the best possible stiffening by the ribs 36, the horizontal leg 37 of the locking strips 28 are provided in the region of the stiffening ribs 36 with recesses 38 whose width in the longitudinal direction of the track conveyor are dimensioned such that the Stiffening ribs 36 enclosing them do not hinder the pivoting mobility of the connecting channel element 22 relative to the receiving plate 19 in the intended pivoting range.

Um die Drehbeweglichkeit des Anschlussrinnenelementes 22 weiter zu begünstigen, ist dieses an seiner Unterseite 24 mit zum Lagerzapfen 25 beabstandet angeordneten Auflager-Gleitelementen 39 versehen, die als quer zur Längsrichtung des Streckenförderers verlaufende Auflagerleisten ausgebildet sind, mit denen das Anschlussrinnenelement 22 auf der Aufnahmeplatte 19 gleitbeweglich aufliegt. Die Auflager-Gleitelemente 39 können aus einem besonders geeigneten Lagerwerkstoff bestehen, der in Kombination mit dem Werkstoff der Aufnahmeplatte einen geringen Reibbeiwert hat und somit ein leichtes Drehen des Anschlussrinnenelementes relativ zur Aufnahmeplatte gewährleistet. Die Gleitelemente 39 können als Verschleißbauteile austauschbar am Anschlussrinnenelement angeordnet sein und dann bei Bedarf gegen Ersatzteile ausgetauscht werden.In order to favor the rotational mobility of the Anschlußrinnenelementes 22 further, this is provided on its underside 24 spaced from the bearing pin 25 arranged Auflager-sliding elements 39, which are formed as transverse to the longitudinal direction of the track conveyor supporting strips, with which the Anschlußrinnenelement 22 slidably rests on the receiving plate 19. The bearing sliding elements 39 may consist of a particularly suitable bearing material, which in combination with the material of the receiving plate has a low coefficient of friction and thus ensures easy turning of the connection channel element relative to the receiving plate. The sliding elements 39 can be arranged as wear components replaceable on the connection channel element and then replaced as needed with spare parts.

Um auch im montierten Zustand des Anschlussrinnenelementes 22 einen leichten Zugang zum Untertrum 40 des Streckenförderers im Bereich der Übergabestation und bevorzugt auch zu dem darunter befindlichen Schwenklager zu schaffen, ist das Anschlussrinnenelement 22 mit einer Revisionsöffnung 41 versehen, die mittels einer von einer Längsaußenseite 42 des Anschlussrinnenelementes 22 einschiebbaren Abdeckplatte 43 verschließbar ist. Die Abdeckplatte wird nach Art einer Schublade in seitlichen, im Schnitt etwa V-förmigen Führungsschienen geführt. Sie ist so bemessen, dass sie im am Anschlussrinnenelement 22 montierten Zustand beidseitig über die seitlichen Begrenzungsprofile 35 des Rinnenelementes 22 vorragt, wobei sie an den vorragenden Bereichen 45 mit Anschlagöffnungen 46 versehen ist, die im montierten Zustand mit an den Begrenzungsprofilen 35 ausgebildeten Arretierösen 47 fluchten, wobei zur Arretierung Befestigungsbolzen 48 durch die Anschlagöffnungen 46 und die Arretierösen gesteckt und in der eingesteckten Lage verriegelt sind.In order to provide easy access to Untertrum 40 of the track conveyor in the transfer station and preferably also to the underlying pivot bearing in the assembled state of the connection channel element 22, the connection channel element 22 is provided with a revision opening 41, which by means of a longitudinal outer side 42 of the connection channel element 22 insertable cover plate 43 is closed. The cover plate is guided in the manner of a drawer in lateral, approximately V-shaped guide rails in section. It is dimensioned so that it protrudes on both sides in the mounted on the connection channel element 22 on the lateral boundary profiles 35 of the channel element 22, being provided at the protruding portions 45 with stop openings 46 which are aligned in the assembled state with the locking profiles 35 formed locking eyelets , wherein for locking fastening bolts 48 inserted through the stop openings 46 and the locking lugs and locked in the inserted position.

Die Erfindung schafft einen konstruktiv einfachen und preiswerten, gleichwohl höchst zuverlässigen, schwenkbeweglichen Anschluss zwischen Streb- und Streckenförderer, mit dem Winkelabweichungen von einer rechtwinkligen Ausrichtung der beiden Förderer relativ zueinander in einem ausreichend großen Bereich im Wesentlichen automatisch ausgeglichen werden. Dabei ist das Schwenklager leicht zugänglich und die von dem Schwenklager zu übertragenden Kräfte bleiben gering, da die aus dem Gewicht des Hauptantriebes des Strebförderers resultierenden Auflagerkräfte vom seitlich neben der Aufnahmeplatte angeordneten Unterbau in das Liegende abgesetzt werden.The invention provides a structurally simple and inexpensive, yet highly reliable, pivotable connection between longwall and track conveyor, are offset with the angular deviations of a rectangular orientation of the two conveyors relative to each other in a sufficiently large area substantially automatically. In this case, the pivot bearing is easily accessible and the forces to be transmitted from the pivot bearing remain low, since the resulting from the weight of the main drive of the longwall support forces are offset from the laterally arranged next to the receiving plate base in the footing.
