  • einer Hubeinrichtung zur Vertikalverstellung des Teleskopunterteils,
wobei das Füllteleskop zur Anpassung an die jeweilige Position der Füllöffnungen relativ zum Kohlefüllwagen horizontal in zwei zueinander orthogonalen Achsen verstellbar ist.The invention relates to a device for filling furnace chambers of a coke oven with
  • a horizontal auger arranged on the underside of a coal hopper,

Eine Vorrichtung mit den beschriebenen Merkmalen ist aus EP 1 293 552 B1 bekannt. Die Horizontalförderschnecke und das Füllteleskop der bekannten Vorrichtung sind zu einer Betriebseinheit vereinigt, die in zwei Achsen verstellbar an der Unterseite eines Kohlefüllwagens angeordnet ist. Im Rahmen der bekannten Maßnahmen ist die Horizontalförderschnecke an einem Verstellwagen aufgehängt, der auf einer Fahrbahn an der Unterseite des Kohlefüllwagens geführt ist. Die Horizontalförderschnecke ist quer zu dieser Bahnrichtung an Profilen des Verstellwagens beweglich verfahrbar. Durch eine zweiachsige Verstellung der Betriebseinheit kann das Füllteleskop an die jeweilige Lage der Kohlefüllöffnungen in der Ofendecke des Koksofens angepasst werden, so dass das an einem Auslass der Horizontalförderschnecke aufgeschlossene Füllteleskop stets vertikal in den Fülllochrahmen der Füllöffnung dichtend absenkbar ist. Problematisch ist allerdings der Übergang zwischen dem Kohleauslass des Kohlefüllwagens und einem Einlauftrichter der Horizontalförderschnecke. Zur Vermeidung von Emissionen muss dieser Übergangsbereich abgedichtet werden. Bei der bekannten Vorrichtung wird ein Kompensator verwendet, der seitliche Verstellbewegungen der Betriebseinheit in zwei Achsen ausgleichen muss. Der Kohleauslass des Füllwagens weist einen großen Austrittsquerschnitt auf, so dass ein Kompensator mit großen Abmessungen eingesetzt werden muss. Bei der Seitwärtsbewegungen der Betriebseinheit ist der Kompensator einer starken Beanspruchung ausgesetzt. Ein weiterer, gravierender Nachteil der bekannten Vorrichtung ist, dass die bekannte Anordnung einen großen Bodenabstand zwischen dem Kohleauslass an der Unterseite des Kohlefüllwagens und der Ofendecke des Koksofens erfordert. Dieser steht nicht immer zur Verfügung. Die in zwei Achsen bewegliche Aufhängung der Horizontalförderschnecke ist ferner konstruktiv aufwendig. Zum Nachrüsten bestehender Koksofenanlagen ist die bekannte Vorrichtung nicht oder nur mit Einschränkungen geeignet.A device with the described features is made EP 1 293 552 B1 known. The horizontal screw conveyor and the filling telescope of the known device are combined to form an operating unit which is arranged in two axes adjustable on the underside of a coal filling carriage. As part of the known measures, the horizontal screw conveyor is suspended on a Verstellwagen, which is guided on a roadway at the bottom of the coal filling car. The horizontal screw conveyor is movable transversely to this web direction on profiles of the adjusting. By a biaxial adjustment of the operating unit, the filling telescope to the respective Position of Kohlefüllöffnungen be adapted in the furnace roof of the coke oven, so that the aufgreift at an outlet of the horizontal screw auger telescope is always vertically lowered into the Fülllochrahmen the filling opening. The problem, however, is the transition between the coal outlet of the coal hopper and a hopper of horizontal auger. To avoid emissions, this transitional area must be sealed. In the known device, a compensator is used, which must compensate for lateral adjustment movements of the operating unit in two axes. The coal outlet of the filling carriage has a large outlet cross-section, so that a compensator with large dimensions must be used. During sideways movement of the operating unit, the compensator is subjected to heavy stress. Another serious disadvantage of the known device is that the known arrangement requires a large ground clearance between the coal outlet at the bottom of the coal filling carriage and the furnace roof of the coke oven. This is not always available. The movable in two axes suspension of the horizontal screw conveyor is also structurally complex. For retrofitting existing coke oven plants, the known device is not suitable or only with restrictions.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum emissionsfreien Befüllen von Ofenkammern eines Koksofens anzugeben, die einen geringen Platzbedarf benötigt, große Lageabweichungen der Füllöffnungen kompensieren kann und zum Nachrüsten bestehender Koksofenanlagen geeignet ist.The invention has for its object to provide a device for emission-free filling of furnace chambers of a coke oven, which requires a small footprint, can compensate for large deviations in the position of the filling openings and is suitable for retrofitting existing coke oven systems.

Ausgehend von einer Vorrichtung mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass der Einlauftrichter des Füllteleskops sowie die mit dem Füllteleskopunterteil verbundene Hubeinrichtung an einem Tragrahmen befestigt sind, der entlang einer ersten Achse linear verstellbar innerhalb eines Fahrrahmens angeordnet ist, dass der Fahrrahmen auf Schienen, die an der Unterseite des Kohlefüllwagens befestigt sind, entlang einer zweiten Achse horizontal verfahrbar angeordnet ist und dass an der Oberseite des Tragrahmens eine Dichtung angeordnet ist, die den Einlauftrichter des Füllteleskops umgibt, mit einer horizontalen Flanschfläche am Umfang des Auslasses der Horizontalförderschnecke zusammenwirkt und horizontale Verstellbewegungen des Einlauftrichters relativ zum Auslass der Horizontalförderschnecke zulässt.Based on a device with the features described above, the object is achieved in that the inlet funnel of the filling telescope and associated with the Füllteleskopunterteil lifting device are attached to a support frame, which is arranged along a first axis linearly adjustable within a travel frame, that the driving frame on rails, which are fixed to the underside of the coal hopper, is arranged horizontally movable along a second axis and that at the top of the support frame, a seal is arranged, which surrounds the inlet funnel of the Füllteleskops, cooperating with a horizontal flange on the circumference of the outlet of the horizontal screw conveyor and horizontal adjustment movements of the inlet funnel relative to the outlet of the horizontal screw conveyor permits.

Im Idealfall sind die Fülllöcher in der Ofendecke eines Koksofens in äquidistanten Abständen sowie in Fahrtrichtung des Kohlefüllwagens fluchtend angeordnet. Von diesem Idealfall weichen die realen Verhältnisse an einem Koksofen regelmäßig ab. Insbesondere bei älteren Koksöfen betragen die Lageabweichungen der Fülllöcher in beiden Achsen (X, Y) häufig mehr als 50 mm. Der erfindungsgemäßen Vorrichtung liegt die Überlegung zugrunde, Abweichungen der Fülllochachsen in X- und Y-Richtung durch eine horizontale Verstellbewegung des Füllteleskopes zu kompensieren. Zu diesem Zweck ist das Füllteleskop erfindungsgemäß einschließlich seiner vertikalen Hubeinrichtung vom Auslauf der Horizontalförderschnecke abgekoppelt und in einem Fahrwerk angeordnet, welches sich aus einem Fahrrahmen und einem innerhalb des Fahrrahmens linear verstellbaren Tragrahmen zusammensetzt und horizontale Ausgleichsbewegungen in zwei Achsen ermöglicht. Der Tragrahmen sowie der Fahrrahmen sind unabhängig voneinander in zueinander senkrechten Achsen verfahrbar. Lageabweichungen der Fülllochrahmen können durch schrittweises und aufeinander folgendes Verfahren des Fahrrahmens und des Tragrahmens oder durch gleichzeitiges Verstellen dieser Komponenten ausgeglichen werden. Die Aufbauhöhe des aus Fahrrahmen und Tragrahmen bestehenden Fahrwerks ist gering, so dass auch ältere Koksöfen mit der erfindungsgemäßen Vorrichtung nachgerüstet werden können. Ferner ist eine geringe Masse bei der Verstellung des Füllteleskops zu bewegen, was die technische Umsetzung des erfindungsgemäßen Konzeptes vereinfacht.Ideally, the filling holes are arranged in the furnace roof of a coke oven in equidistant intervals and in the direction of travel of the coal filling carriage in alignment. From this ideal case, the real conditions on a coke oven deviate regularly. Especially with older coke ovens, the positional deviations of the filling holes in both axes (X, Y) are often more than 50 mm. The device according to the invention is based on the consideration to compensate for deviations of Fülllochachsen in the X and Y directions by a horizontal adjustment of the filling telescope. For this purpose, the filling telescope according to the invention is decoupled, including its vertical lifting device from the outlet of the horizontal screw conveyor and arranged in a chassis, which is composed of a traveling frame and a linearly adjustable within the traveling frame support frame and horizontal compensation movements in two axes. The support frame and the driving frame are independently movable in mutually perpendicular axes. Positional deviations of the Fülllochrahmen can be compensated for by gradual and sequential movement of the traveling frame and the support frame or by simultaneously adjusting these components. The construction height of existing chassis and support frame chassis is low, so that even older coke ovens can be retrofitted with the device according to the invention. Furthermore, a small mass in the adjustment of the Füllteleskops to move, which simplifies the technical implementation of the inventive concept.

Nachdem das Füllteleskop durch Verstellen des Fahrrahmens sowie des Tragrahmens exakt oberhalb einer Füllöffnung positioniert worden ist, führt das Füllteleskop durch die Hubvorrichtung eine reine Vertikalbewegung in Richtung des Fülllochrahmens aus und gelangt ohne jede Schrägstellung zur Anlage im Fülllochrahmen. Im Ergebnis resultiert eine gute Abdichtung am Fülllochrahmen, so dass keine Emissionen während des Befüllvorganges nach außen in die Umwelt gelangen können.After the filling telescope has been positioned by adjusting the traveling frame and the support frame exactly above a filling opening, the filling telescope performs by the lifting a pure vertical movement in the direction of Fülllochrahmens and passes without any inclination to rest in the Fülllochrahmen. The result is a good seal on the Fülllochrahmen so that no emissions during the filling process can get out into the environment.

Der Fahrrahmen und der Tragrahmen sind vorzugsweise in einer Ebene angeordnet. Eine solche Anordnung führt zu einer sehr geringen Aufbauhöhe des aus Fahrrahmen und Tragrahmen bestehenden Fahrwerks. Der Fahrrahmen und der Tragrahmen sind zweckmäßig aus U-Profilen zusammengesetzt, wobei an dem Tragrahmen Rollen gelagert sind, die in den U-Profilen des Fahrrahmens laufen. Der Fahrrahmen ist ebenfalls mit Rollen ausgestattet und läuft in einer Fahrbahn, welche unterhalb der Horizontalförderschnecke des Kohlefüllwagens befestigt ist. Vorzugsweise bestehen die Schienen für den Fahrrahmen aus U-Profilen, die mit Trägern an dem Kohlefüllwagen abgehängt und seitlich offen sind. Die an dem Fahrrahmen gelagerten Rollen greifen in die an einer Seite offenen U-Profile ein und laufen in diesen Schienen.The traveling frame and the supporting frame are preferably arranged in one plane. Such an arrangement results in a very low construction height of existing chassis and support frame chassis. The traveling frame and the supporting frame are expediently composed of U-profiles, wherein rollers are mounted on the supporting frame, which run in the U-profiles of the driving frame.

Zur Vermeidung von Emissionen bei der Befüllung der Koksofenkammern eines Koksofens ist an der Oberseite des Tragrahmens eine Dichtung vorgesehen, die den Einlauftrichter des Füllteleskops umgibt und während der Kohlebefüllung an einer horizontalen Flanschfläche am Umfang des Auslasses der Horizontalförderschnecke anliegt. Vorzugsweise ist die Dichtung betriebsmäßig dergestalt verstellbar, dass die Dichtung während einer Horizontalverstellung des Füllteleskops keinen Berührungskontakt mit der benachbarten Flanschfläche hat und während der Kohlebefüllung an der Flanschfläche dichtend anliegt. Die an der Oberseite des Tragrahmens angeordnete Dichtung kann insbesondere als Membran, als balg- oder schlauchförmige Dichtung ausgebildet sein, die in einem Ringraum angeordnet und mit Druckluft oder einem anderen Druckmedium aufweitbar ist. Der Einlauftrichter des Füllteleskops weist zweckmäßig einen zylindrischen Abschnitt auf, der von einem Zylinderabschnitt des Teleskopunterteils umgeben ist. Am Umfang zwischen dem zylindrischen Abschnitt des Einlauftrichters und dem Zylinderabschnitt des Teleskopunterteils ist ebenfalls eine Umfangsdichtung angeordnet, die vorzugsweise betriebsmäßig veränderbar ist und eine im Wesentlichen berührungsfreie Verstellbewegung des Teleskopunterteils zulässt. Die Umfangsdichtung kann ebenso wie die Dichtung an der Oberseite des Tragrahmens als Schlauch, Balg oder Membran ausgebildet und an eine Druckquelle angeschlossen sein. Bei Arbeitsbewegungen des Füllteleskops in horizontaler oder vertikaler Richtung sind die Dichtungen druckentlastet, so dass die abzudichtenden Teile gegeneinander frei beweglich sind. Hat das Füllteleskop seine Endposition für den Befüllvorgang erreicht, werden die Dichtungen mit Druckluft oder einem anderen Druckmedium beaufschlagt. Durch die Druckbeaufschlagung wölben sich die Dichtungen nach außen und pressen sich gegen die zugeordneten Flächen der abzudichtenden Teile. Auf diese Weise ist eine optimale Dichtheit während des Befüllvorgangs sichergestellt.To avoid emissions when filling the coke oven chambers of a coke oven, a seal is provided at the top of the support frame surrounding the inlet funnel of the Füllteleskops and rests during the coal filling at a horizontal flange on the circumference of the outlet of the horizontal screw conveyor. Preferably, the seal is operatively adjustable such that the seal during a horizontal adjustment of the filling telescope has no physical contact with the adjacent flange surface and sealingly abuts the flange during the coal filling. The arranged at the top of the support frame seal may be formed in particular as a membrane, as a bellows or tubular seal, which is arranged in an annular space and can be expanded with compressed air or other pressure medium. The inlet funnel of the Füllteleskops expediently has a cylindrical portion which is surrounded by a cylindrical portion of the telescopic lower part. At the periphery between the cylindrical portion of the inlet funnel and the cylinder portion of the telescopic lower part, a circumferential seal is also arranged, which is preferably operatively changed and allows a substantially contact-free adjustment movement of the telescopic lower part. The peripheral seal may, like the seal at the top of the support frame as a hose, bellows or membrane formed and connected to a pressure source. During working movements of the filling telescope in the horizontal or vertical direction, the seals are depressurized, so that the parts to be sealed against each other are free to move. When the filling telescope has reached its final position for the filling process, the seals are pressurized with compressed air or another pressure medium. By applying pressure, the seals bulge outwards and press against the associated surfaces of the parts to be sealed. In this way, an optimal tightness during the filling process is ensured.

Für die horizontalen Stellbewegungen des Tragrahmens und des Fahrrahmens werden vorzugsweise hydraulische Stelleinrichtungen verwendet. Gemäß einer bevorzugten Ausführung der Erfindung sind an den Tragrahmen und den Fahrrahmen hydraulische Stelleinrichtungen angeschlossen, die mit Weg-Messeinrichtungen ausgestattet sind.Hydraulic actuators are preferably used for the horizontal positioning movements of the support frame and the travel frame. According to a preferred embodiment of the invention, hydraulic adjusting devices are connected to the support frame and the driving frame, which are equipped with path measuring devices.

Die hydraulischen Stelleinrichtungen sind an eine Maschinensteuerung des Kohlefüllwagens anschließbar, in der Positionsangabe für die Lage der Füllöffnungen in der Ofendecke des Koksofens hinterlegt sind. Die Abweichungen der Fülllochrahmen in X- und Y-Richtung von der Ideallage werden an jedem Fülllochrahmen messtechnisch erfasst und in der Maschinensteuerung des Kohlefüllwagens hinterlegt. Infolge der Zuordnung dieser Abweichungen zu jedem Fülllochrahmen und jeder Ofenkammer, kann das Füllteleskop mit der erfindungsgemäßen Vorrichtung schon während der Fahrt des Kohlefüllwagens oder alternativ nach der Positionierung des Kohlefüllwagens auf der zu befüllenden Ofenkammer individuell so verstellt werden, dass das Füllteleskop mittig zum Fülllochrahmen ausgerichtet ist und durch eine reine Vertikalbewegung in den Fülllochrahmen abgesenkt werden kann. Durch die reine Vertikalbewegung entfallen seitliche Bewegungen und Schrägstellungen von Teleskopbauteilen des Füllteleskops. Es wird somit sichergestellt, dass alle Bauelemente des Füllteleskops optimal funktionieren und keinerlei Emissionen während des Befüllvorgangs außen in die Umwelt gelangen.The hydraulic actuating devices can be connected to a machine control of the coal filling carriage, are stored in the position information for the position of the filling openings in the furnace roof of the coke oven. The deviations of the Fülllochrahmen in the X and Y direction of the ideal position are detected metrologically on each Fülllochrahmen and deposited in the machine control of the coal filling car. As a result of the assignment of these deviations to each Fülllochrahmen and each furnace chamber, the Füllteleskop can be adjusted individually with the device according to the invention already while driving the Kohlefüllwagens or alternatively after positioning the Kohlefüllwagens on the furnace chamber to be filled so that the filling telescope is centered to the Fülllochrahmen and can be lowered by a pure vertical movement in the Fülllochrahmen. The pure vertical movement accounts for lateral movements and inclinations of telescopic components of the filling telescope. This ensures that all components of the filling telescope function optimally and that no emissions are released into the environment during the filling process.

Eine weitere Ausgestaltung der erfindungsgemäßen Vorrichtung sieht vor, dass die hydraulischen Stelleinrichtungen mit einer optischen Messeinrichtung zusammenwirken, welche an dem Kohlefüllwagen angeordnet ist und die tatsächliche Lage der Füllöffnungen erfasst. Die Messdaten werden direkt an die Steuerung der Hydraulikzylinder weitergeleitet, welche dann das Füllteleskop horizontal in eine der Lage des Fülllochrahmens zugeordnete Position bewegen.A further embodiment of the device according to the invention provides that the hydraulic actuating devices cooperate with an optical measuring device, which is arranged on the coal filling carriage and detects the actual position of the filling openings. The measurement data are forwarded directly to the control of the hydraulic cylinders, which then move the filling telescope horizontally in a position associated with the Fülllochrahmens position.

Eine Vorrichtung zum Befüllen von Ofenkammern des Koksofens weist vielfach zusätzlich eine Deckelabhebevorrichtung zur Manipulation eines das Füllloch verschließenden Deckels sowie eine Vorrichtung zur Reinigung der Fülllochrahmen auf. Die Deckelabhebevorrichtung und eine Vorrichtung zur Reinigung des Fülllochrahmens können in der erfindungsgemäßen Vorrichtung integriert werden. In weiterer Ausgestaltung lehrt die Erfindung, dass innerhalb des Tragrahmens mindestens ein Laufwagen angeordnet ist, der entlang den Profilen des Tragrahmens verfahrbar ist und als Träger für eine Deckelabhebevorrichtung oder eine Vorrichtung zur Reinigung der Fülllochrahmen genutzt wird. Die an dem Laufwagen angeordnete Vorrichtung weist einen vertikal verstellbaren Tragarm auf, der durch eine Stellbewegung des Laufwagens in einen Freiraum zwischen dem angehobenen Teleskopunterteil des Füllteleskopes und dem Fülllochrahmen bewegbar ist und mit einer Einrichtung zum Erfassen eines das Füllloch verschließenden Deckels oder zum Reinigen des Fülllochrahmens ausgestattet ist. Für die horizontalen Stellbewegungen des Laufwagens wird zweckmäßig ebenfalls eine hydraulische Stelleinrichtung verwendet, die auf den Laufwagen wirkt.A device for filling furnace chambers of the coke oven in many cases additionally comprises a cover lifting device for manipulating a cover closing the filling hole and a device for cleaning the filling hole frames. The Deckelabhebevorrichtung and a device for cleaning the Fülllochrahmens can be integrated in the device according to the invention. In a further embodiment, the invention teaches that at least one carriage is arranged within the support frame, which is movable along the profiles of the support frame and is used as a support for a Deckelabhebevorrichtung or a device for cleaning the Fülllochrahmen. The arranged on the carriage device comprises a vertically adjustable support arm, which is movable by an adjusting movement of the carriage in a space between the raised telescopic lower part of the filling telescope and the Fülllochrahmen and equipped with a device for detecting a filling hole closing lid or for cleaning the Fülllochrahmens is. For the horizontal adjusting movements of the carriage, a hydraulic adjusting device is also suitably used, which acts on the carriage.

Das Füllteleskop 2 ist zur Anpassung an die jeweilige Position der Füllöffnungen 5 relativ zum Kohlefüllwagen horizontal in zwei zueinander orthogonalen Achsen X, Y verstellbar.For the basic structure of the in the Fig. 1 to 3 The apparatus shown include a arranged on the underside of a coal feeder, not shown horizontal screw conveyor 1, a filling telescope 2, which is arranged below an outlet 3 of the horizontal screw conveyor and an inlet funnel 4 and a filling openings 5 in the furnace ceiling of the coke oven vertically lowerable telescopic base 6, and a Lifting device 7 for vertical adjustment of the telescopic lower part 6. The filling telescope 2 is to adjust to the respective position of the filling openings 5 relative to the coal filling horizontally in two mutually orthogonal axes X, Y adjustable.

Der Einlauftrichter 4 des Füllteleskops 2 sowie die mit dem Teleskopunterteil 6 verbundene Hubeinrichtung 7 sind an einem Tragrahmen 8 befestigt, der entlang einer ersten Achse X linear verstellbar innerhalb eines Fahrrahmens 9 angeordnet ist. Der Fahrrahmen 9 ist auf Schienen 10, die an der Unterseite des Kohlefüllwagens befestigt sind, entlang einer zweiten Achse Y horizontal verfahrbar angeordnet. An der Oberseite des Tragrahmens 8 ist ferner eine Dichtung 11 angeordnet, die den Einlauftrichter 4 des Füllteleskops umgibt, mit einer horizontalen Flanschfläche 12 am Umfang des Auslasses 3 der Horizontalförderschnecke 1 zusammenwirkt und horizontale Verstellbewegungen des Einlauftrichters 4 relativ zum Auslass 3 der Horizontalförderschnecke 1 in zwei Achsen X, Y zulässt. In dem in den Fig. 1 bis 3 dargestellten Ausführungsbeispiel erstrecken sich die Schienen 10 zur Führung des Fahrrahmens 9 in Bewegungsrichtung Y des Kohlefüllwagens. Der Tragrahmen 8 ist quer dazu in Richtung X der Ofenkammerachsen verfahrbar an dem Fahrrahmen 9 geführt.The inlet funnel 4 of the filling telescope 2 and the lifting device 7 connected to the telescopic lower part 6 are fastened to a support frame 8 which is arranged linearly adjustable within a traveling frame 9 along a first axis X. The traveling frame 9 is arranged horizontally movable on rails 10, which are fixed to the underside of the coal filling carriage, along a second axis Y. At the top of the support frame 8, a seal 11 is further arranged, which surrounds the inlet funnel 4 of the Füllteleskops, cooperates with a horizontal flange 12 on the circumference of the outlet 3 of the horizontal screw conveyor 1 and horizontal adjustment movements of the inlet funnel 4 relative to the outlet 3 of the horizontal screw conveyor 1 in two Axles X, Y permits. In the in the Fig. 1 to 3 illustrated embodiment, the rails 10 extend to guide the traveling frame 9 in the direction of movement Y of the coal filling carriage. The support frame 8 is guided transversely thereto in the direction X of the furnace chamber axes movable on the traveling frame 9.

Aus den Darstellungen in den Fig. 1 bis 3 ist ersichtlich, dass der Fahrrahmen 9 und der Tragrahmen 8 in einer Ebene angeordnet sind. Beide Rahmen sind aus U-Profilen 13, 14 aufgebaut. An dem Tragrahmen 8 sind Rollen 15 gelagert, die in den U-Schienen 14 des Fahrrahmens 9 laufen. Die Schienen 10 für den Fahrrahmen 9 bestehen ebenfalls aus U-Profilen, die mit Trägern 16 an dem nicht dargestellten Kohlefüllwagen abgehängt und seitlich offen sind. An dem Fahrrahmen 9 sind Rollen 17 gelagert, die in den seitlich offenen Schienen 10 laufen. Der Fahrrahmen 9 und der innerhalb des Fahrrahmens angeordnete Tragrahmen 8 bilden ein Fahrwerk, das horizontale Verstellbewegungen des Füllteleskops in X- und Y-Richtung zulässt.From the representations in the Fig. 1 to 3 it can be seen that the traveling frame 9 and the support frame 8 are arranged in one plane. Both frames are constructed of U-profiles 13, 14. On the support frame 8 rollers 15 are mounted, which run in the U-rails 14 of the traveling frame 9. The rails 10 for the travel frame 9 are also made of U-profiles, which are suspended with carriers 16 on the coal filling carriage, not shown, and laterally open. To the Chassis 9 rollers 17 are mounted, which run in the laterally open rails 10. The traveling frame 9 and the support frame 8 arranged within the traveling frame form a running gear which permits horizontal displacement movements of the filling telescope in the X and Y directions.

Die Hubeinrichtung 7 für das Füllteleskop 2 weist einen an einem Vertikalträger 18 geführten Hubrahmen 19 auf. Der Hubrahmen 19 ist mittels einer hydraulischen Stelleinrichtung 20 entlang des Vertikalträgers 18 verfahrbar und durch Pendelelemente 21 mit dem Teleskopunterteil 6 verbunden. Die vertikale Verstellbewegung ist in Fig. 2 schematisch dargestellt. Ferner ist in Fig. 2 der Tragrahmen 8 um einen Stellweg X0 gegenüber einer Mittellage in X-Richtung verschoben worden. Die Stellwege X0, Y0 in beiden Achsrichtungen betragen beispielsweise ±100 bis ±150 mm. Der Vertikalträger 18 der Hubeinrichtung 7 ist mit seitlichem Versatz zur Horizontalförderschnecke 1 an dem Tragrahmen 8 befestigt.The lifting device 7 for the filling telescope 2 has a guided on a vertical support 18 lifting frame 19. The lifting frame 19 is movable by means of a hydraulic adjusting device 20 along the vertical support 18 and connected by pendulum elements 21 to the telescopic base 6. The vertical adjustment movement is in Fig. 2 shown schematically. Furthermore, in Fig. 2 the support frame 8 has been displaced by a travel X 0 relative to a central position in the X direction. The travel paths X 0 , Y 0 in both axial directions are for example ± 100 to ± 150 mm. The vertical support 18 of the lifting device 7 is attached to the support frame 8 with a lateral offset to the horizontal screw conveyor 1.

Die an der Oberseite des Tragrahmens 8 angeordnete Dichtung 11 ist als Membran, balg- oder schlauchförmige Dichtung ausgebildet. Sie ist in einem Ringraum 22 angeordnet und mit Druckluft aufweitbar. Die Dichtung 11 ist dadurch betriebsmäßig verstellbar, so dass sie während einer Horizontalverstellung des Füllteleskops 2 mit der den Auslass der Horizontalförderschnecke umgebenden Flanschfläche 12 keinen Berührungskontakt hat und während einer Kohlebefüllung an der Flanschfläche 12 dichtend anliegt und den Spalt zwischen dem Flansch und der Oberseite des Tragrahmens 8 abdichtet.The arranged at the top of the support frame 8 seal 11 is formed as a diaphragm, bellows or tubular seal. It is arranged in an annular space 22 and expandable with compressed air. The seal 11 is thus operatively adjustable so that it during a horizontal adjustment of the Füllteleskops 2 with the outlet of the horizontal screw conveyor surrounding flange surface 12 has no physical contact and during a coal filling on the flange 12 sealingly abuts and the gap between the flange and the top of the support frame 8 seals.

Der Einlauftrichter 4 des Füllteleskops 2 weist einen zylindrischen Abschnitt auf, der von einem Zylinderabschnitt des Teleskopunterteils umgeben ist. Am Umfang zwischen dem zylindrischen Abschnitt des Einlauftrichters 4 und dem Zylinderabschnitt des Teleskopunterteils 6 ist eine Umfangsdichtung 23 angeordnet, die ebenfalls betriebsmäßig veränderbar ist und eine im Wesentlichen berührungsfreie Verstellbewegung des Teleskopunterteils 6 zulässt.The inlet funnel 4 of the filling telescope 2 has a cylindrical portion which is surrounded by a cylindrical portion of the telescopic lower part. At the circumference between the cylindrical portion of the inlet funnel 4 and the cylinder portion of the telescopic lower part 6, a circumferential seal 23 is arranged, which is also operationally variable and allows a substantially non-contact adjustment movement of the telescopic lower part 6.

An den Tragrahmen 8 und den Fahrrahmen 9 sind hydraulische Stelleinrichtungen 24 angeschlossen, die mit Weg-Messeinrichtungen ausgestattet sind. Die hydraulischen Stelleinrichtungen 24 sind an eine Maschinensteuerung des Kohlefüllwagens anschließbar, in der Positionsangaben für die Lage der Füllöffnungen 5 in der Ofendecke des Kohleofens hinterlegt sind. Alternativ können die hydraulischen Stelleinrichtungen 24 mit einer optischen Messeinrichtung zusammenwirken, welche an dem Kohlefüllwagen angeordnet ist und die Lage der Füllöffnungen 5 erfasst.To the support frame 8 and the chassis 9 hydraulic adjusting devices 24 are connected, which are equipped with path measuring devices. The hydraulic actuating devices 24 can be connected to a machine control of the coal filling carriage, in which position data for the position of the filling openings 5 are deposited in the furnace roof of the coal furnace. Alternatively, the hydraulic actuators 24 can cooperate with an optical measuring device which is arranged on the coal filling carriage and detects the position of the filling openings 5.

Die beschriebene Vorrichtung ermöglicht eine sehr präzise Ausrichtung des Füllteleskops 2 an den Füllöffnungen 5 in der Ofendecke eines Koksofens und ist in der Lage, betrieblich bedingte Lageabweichungen der Füllöffnungen von einer vorgegebenen Grundposition in X- und Y-Richtung zu kompensieren. Bei älteren Kokereien können die Lageabweichungen oftmals in der Größenordnung von ± 100 bis 150 mm in beiden Achsen X, Y betragen. Die horizontalen Lageabweichungen X, Y der Fülllochrahmen 25 werden in Längs- und Querrichtung gemessen und für jeden Fülllochrahmen in einer Maschinensteuerung auf dem Kohlefüllwagen gespeichert sowie nach Bedarf aktualisiert. Der Kohlefüllwagen wird auf der Ofendecke des Koksofens verfahren und ohne Berücksichtigung der Lageabweichungen der Füllöffnungen 5 zur Befüllung einer Ofenkammer an einer vorgegebenen Stelle, die der Füllöffnung zugeordnet ist, positioniert. Die Positionierung kann beispielsweise unter Zuhilfenahme eines automatischen Positionierungssystems mit hoher Positioniergenauigkeit vorgenommen werden. Anschließend erfolgt die Anpassung des Füllteleskops 2 an die tatsächliche Lage des Fülllochrahmens 25. Dazu werden der Fahrrahmen 9 und der Tragrahmen 8 nach Maßgabe der gespeicherten X/Y-Werte für die Lageabweichung des Fülllochrahmens 25 in eine der tatsächlichen Lage des Fülllochrahmens zugeordnete Position gebracht. Das Teleskopunterteil 6 des Füllteleskops 2 wird danach vertikal in den Fülllochrahmen 25 abgesenkt. Nach erfolgter Absenkung des Teleskopunterteils 6 werden die Dichtungen 11, 23 an der Oberseite des Tragrahmens sowie umfangsseitig zwischen dem Teleskopunterteil 6 und dem Einlauftrichter 4 des Füllteleskops 2 durch Beaufschlagung mit Druckluft aktiviert. Durch die Druckbeaufschlagung weiten oder wölben sich die Dichtungen 11, 23 und pressen sich an die jeweiligen Kontaktflächen an. Nach erfolgter Befüllung werden die Dichtungen 11, 23 vor dem Anheben des Teleskopunterteils 6 wieder deaktiviert und wird das Teleskopunterteil 6 anschließend hochgefahren. Danach können der Fahrrahmen 9 und der Tragrahmen 8, z.B. während einer Rückfahrt des Kohlefüllwagens zum Kohleturm, wieder in eine Ausgangslage zurückbewegt werden.The device described allows a very precise alignment of the filling telescope 2 at the filling openings 5 in the furnace roof of a coke oven and is able to compensate for operational positional deviations of the filling openings from a predetermined basic position in the X and Y directions. For older coking plants, the positional deviations can often be on the order of ± 100 to 150 mm in both axes X, Y. The horizontal position deviations X, Y of the Fülllochrahmen 25 are measured in the longitudinal and transverse directions and stored for each Fülllochrahmen in a machine control on the coal hopper and updated as needed. The Kohlefüllwagen is moved on the furnace roof of the coke oven and without consideration of the positional deviations of the filling openings 5 for filling a furnace chamber at a predetermined location which is associated with the filling opening, positioned. The positioning can be done for example with the aid of an automatic positioning system with high positioning accuracy. Thereafter, the adjustment of the filling telescope 2 to the actual position of the Fülllochrahmens 25. For this, the traveling frame 9 and the support frame 8 are brought in accordance with the stored X / Y values for the positional deviation of Fülllochrahmens 25 in one of the actual position of the Fülllochrahmens associated position. The telescopic lower part 6 of the Füllteleskops 2 is then lowered vertically into the Fülllochrahmen 25. After the lowering of the telescopic lower part 6, the seals 11, 23 at the top of the support frame and circumferentially activated between the telescopic lower part 6 and the inlet funnel 4 of the filling telescope 2 by applying compressed air. As a result of the pressurization, the seals 11, 23 widen or bulge and press against the respective contact surfaces. After filling, the seals 11, 23 are deactivated again before raising the telescopic lower part 6 and the telescopic lower part 6 is then raised. Thereafter, the traveling frame 9 and the support frame 8, for example, during a return journey of the coal filling car to the coal tower, be moved back to an initial position.

Nachdem das Füllteleskop 2 durch Fahrbewegungen des Fahrrahmens 9 und des Tragrahmens 8 an die Lage des Fülllochrahmens 25 angepasst ist, wird vor dem Absenken des Teleskopunterteils 6 zunächst die Deckelabhebevorrichtung 26 durch eine Stellbewegung des Laufwagens 27 in Position gebracht. Der Laufwagen 27 führt einen vorgegebenen konstanten Stellweg aus, wobei die Einrichtung zum Erfassen eines das Füllloch verschließenden Deckels mittig über dem Deckel platziert wird. Der Deckel wird aus dem Füllloch ausgedreht. Durch eine vertikale Stellbewegung des Tragarms 28 kann der Deckel angehoben und durch eine Rückfahrt des Laufwagens 27 aus dem Bereich des Füllteleskops 2 entfernt werden. Anschließend wird das Teleskopunterteil 6 in den Fülllochrahmen 25 abgesenkt und die Koksofenkammer befüllt. Nach Beendigung des Befüllvorganges und nach Anheben des Teleskopunterteils 6 aus dem Fülllochrahmen 25 wird der Deckel mit Hilfe der Deckelabhebvorrichtung 26 wieder in den Fülllochrahmen 25 eingesetzt.After the filling telescope 2 is adapted by driving movements of the driving frame 9 and the support frame 8 to the position of the Fülllochrahmens 25, before the lowering of the telescopic lower part 6, the Deckelabhebevorrichtung first 26 brought by an adjusting movement of the carriage 27 in position. The carriage 27 performs a predetermined constant travel, wherein the means for detecting a cover closing the filling hole is placed centrally above the lid. The lid is turned out of the filling hole. By a vertical adjusting movement of the support arm 28, the lid can be lifted and removed by a return travel of the carriage 27 from the area of the filling telescope 2. Subsequently, the telescopic lower part 6 is lowered into the Fülllochrahmen 25 and filled the coke oven chamber. After completion of the filling process and after lifting the telescopic lower part 6 from the Fülllochrahmen 25, the lid with the help of Deckelabhebvorrichtung 26 is inserted back into the Fülllochrahmen 25.
