Beschreibung:Description:
Die Erfindung betrifft eine Vorrichtung an einem Kohlefüllwagen zum Abheben von Deckeln aus Fülllochrahmen in der Ofendecke eines Koksofens und zum Reinigen der Fülllochrahmen, - mitThe invention relates to a device on a Kohlefüllwagen for lifting lids from Fülllochrahmen in the furnace roof of a coke oven and for cleaning the Fülllochrahmen - with

Hubeinrichtungen zur Vertikalverstellung der Tragarme,Lifting devices for vertical adjustment of the support arms,
wobei der Deckelabheber und der Rahmenreiniger jeweils mittels eines Fahrwerks zwischen einer Betriebsposition, in der der Hubmagnet oder der Reinigungskopf mit einem Füllloch in der Ofendecke des Koksofens fluchtet, und einer von dem Füllloch beabstandeten Ruheposition horizontal verfahrbar sind.wherein the Deckelabheber and the frame cleaner are each movable by means of a chassis between an operating position in which the solenoid or the cleaning head is aligned with a filling hole in the furnace ceiling of the coke oven, and spaced from the filling hole rest position horizontally.
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 häufig +- 50 mm, die mit fachüblichen Zentrierhilfen nicht kompensiert werden können. Das hat zur Folge, dass die Fülllochdeckel nicht mehr selbsttätig abgehoben und später in den Fülllochrahmen selbsttätig eingesetzt werden können und dass die Fülllochrahmenreinigung ebenfalls nicht mehr zufriedenstellend funktioniert. Im Kokereibetrieb entstehen hierdurch Unterbrechungen im automatischen Ablauf des Kohlefüllwagens und sind personalintensive Eingriffe notwendig. Des weiteren müssen Fülllochrahmen auf der Ofendecke häufig nachjustiert werden, damit Deckelabheber und Rahmenreiniger ordnungsgemäß arbeiten können. Dadurch entstehen dem Kokereibetrieb beachtliche Instandhaltungskosten.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 often amount to + - 50 mm, which can not be compensated with customary centering aids. That has to Result that the fill hole cover can not be lifted automatically and later used in the Fülllochrahmen automatically and that the Fülllochrahmenreinigung also no longer works satisfactorily. In the coking plant, this causes interruptions in the automatic operation of the coal filling truck and requires personnel-intensive intervention. Furthermore, Fülllochrahmen must often be readjusted on the furnace roof, so Deckelabheber and frame cleaner can work properly. This gives the coking plant considerable maintenance costs.
Aus EP 1 293 552 B1 ist es bekannt, Vorrichtungen zum Abheben von Deckeln aus Fülllochrahmen und zum Reinigen der Fülllochrahmen mit einer Kohlebefüllvorrichtung, die eine Horizontalförderschnecke mit einem auslaufseitigen Füllteleskop aufweist, zu einer Betriebseinheit zu vereinigen, 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 können der Deckelabheber sowie der Rahmenreiniger an die jeweilige Lage der Fülllöcher in der Ofendecke des Koksofens angepasst werden. Mit der bekannten Anordnung können der Hubmagnet des Deckelabhebers und der Reinigungskopf des Rahmenreinigers in eine Betriebsposition gebracht werden, in der sie mit dem Füllloch in der Ofendecke des Koksofens fluchten. Die bekannte Anordnung erfordert jedoch einen großen Bodenabstand zwischen dem Kohleauslass an der Unterseite des Kohlefüllwagens, da die Betriebseinheit am einlaufseitigen Ende der Horizontalförderschnecke mittels eines Kompensators, der seitliche Verstell beweg u ngen der Betriebseinheit in zwei Achsen ausgleichen muss, angeschlossen ist. Dieser Einbauraum steht nicht immer zur Verfügung. Zum Nachrüsten bestehender Koksofenanlagen ist die bekannte Vorrichtung nicht oder nur mit Einschränkungen geeignet.From EP 1 293 552 B1 it is known to unite devices for lifting lids from Fülllochrahmen and for cleaning the Fülllochrahmen with a coal filling device having a horizontal screw conveyor with a discharge-side Füllteleskop to an operating unit, adjustable in two axes on the underside of a Coal filling carriage is arranged. 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 of Deckelabheber and the frame cleaner can be adapted to the respective position of the filling holes in the furnace roof of the coke oven. With the known arrangement, the lifting magnet of the Deckelabhebers and the cleaning head of the frame cleaner can be brought into an operating position in which they are aligned with the filling hole in the furnace roof of the coke oven. However, the known arrangement requires a large ground clearance between the coal outlet at the bottom of the coal hopper, since the operating unit at the inlet end of the horizontal screw conveyor by means of a compensator, the lateral adjustment movements of the operating unit must balance in two axes, is connected. This installation space is not always available. To the Retrofitting existing coke oven systems, the known device is not suitable or only with restrictions.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit der eingangs beschriebenen Zweckbestimmung anzugeben, die einen geringen Platzbedarf benötigt, große Lageabweichungen der Fülllöcher kompensieren kann und zum Nachrüsten bestehender Koksofenanlagen geeignet ist.The invention has for its object to provide a device with the purpose described above, which requires a small footprint, can compensate for large positional deviations of the filling holes 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 das Fahrwerk einen auf Schienen an der Unterseite des Kohlefüllwagens entlang einer ersten Achse horizontal verfahrbaren Fahrrahmen und einen innerhalb des Fahrrahmens angeordneten Tragrahmen aufweist, wobei der Tragrahmen entlang einer zweiten Achse quer zur Bewegungsrichtung des Fahrrahmens beweglich am Fahrrahmen geführt ist, und wobei an dem Tragrahmen die Hubeinrichtung für den Deckelabheber und/oder dem Rahmenreiniger angeordnet ist. Der Tragrahmen sowie der Fahrrahmen sind unabhängig voneinander in zueinander senkrechten Achsen horizontal 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.Based on a device having the features described above, the object is achieved in that the chassis has a rail on the underside of the coal filling carriage along a first axis horizontally movable traveling frame and a support frame arranged within the driving frame, wherein the support frame along a second axis transversely to the direction of movement of the traveling frame is movably guided on the running frame, and wherein on the support frame, the lifting device for the Deckelabheber and / or the frame cleaner is arranged. The support frame and the running frame are independently movable horizontally 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.
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, die an der Unterseite 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 support frame are suitably composed of U-profiles, wherein rollers are mounted on the support frame, which in the U-profiles of the traveling frame run. The chassis is also equipped with wheels and runs in a carriageway, which is attached to the underside of the coal hopper. Preferably, the rails for the traveling frame made of U-profiles, which are suspended with carriers on the coal filling and open at the side. The rollers mounted on the traveling frame engage in the open on one side U-profiles and run in these rails.
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 Positionsangaben für die Lage der Fülllöcher 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 können der Deckelabheber sowie der Rahmenreiniger durch Stellbewegungen des zugeordneten Fahrwerks so positioniert werden, dass der Hubmagnet des Deckelabhebers bzw. der Reinigungskopf des Rahmenreinigers mittig zum Fülllochrahmen ausgerichtet sind und durch eine reine Vertikalbewegung auf den Deckel bzw. in den Fülllochrahmen abgesenkt werden können. Es entfallen Pendelbewegungen und extreme Schrägstellungen der Vorrichtung, so dass alle Bauelemente der Vorrichtung optimal funktionieren und die Fülllochdeckel sicher abgehoben bzw. wieder in den Rahmen eingesetzt werden können und die Fülllochrahmen funktionssicher gereinigt werden können. In der Praxis übliche Zentrierhilfen auf den Fülllochdeckeln, welche unter dem Gesichtspunkt des Unfallschutzes ein Risiko darstellen, entfallen. Die zweiachsigen Verstellbewegungen der Fahrwerke zur Positionskorrektur des Deckelabhebers und des Rahmenreinigers können wahlweise schon während der Fahrt des Kohlefüllwagens oder nach der Positionierung des Kohlefüllwagens auf der zu befüllenden Ofenkammer vorgenommen werden.The hydraulic control 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 holes 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 oven chamber Deckelabheber and the frame cleaner can be positioned by adjusting movements of the associated chassis so that the solenoid of Deckelabhebers or the cleaning head of the frame cleaner are centered to the Fülllochrahmen and by a pure vertical movement on the lid or can be lowered into the Fülllochrahmen. It eliminates oscillations and extreme inclinations of the device, so that all components of the device work optimally and the Fülllochdeckel safely lifted or reinserted into the frame and the Fülllochrahmen can be functionally cleaned. In practice, customary centering on the Fülllochdeckeln, which from the point of view accident risk pose a risk. The biaxial adjustment movements of the trolleys for correcting the position of the Deckelabhebers and the frame cleaner can be made either while driving the coal filling car or after the positioning of the coal filling car on the furnace chamber to be filled.
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 das Fahrwerk des Deckelabhebers und das Fahrwerk des Rahmenreinigers 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 cylinder, which move the chassis of the Deckelabhebers and the chassis of the frame cleaner in a position assigned to the Fülllochrahmens position.
Im Rahmen der Erfindung liegt es, dass die Hubeinrichtungen für den Deckelabheber und den Rahmenreiniger fest an den Tragrahmen des zugeordneten Fahrwerks angeschlossen sind. Die auf den Tragrahmen wirkende Stelleinrichtung ist in diesem Fall mit einer Weg-Messeinrichtung ausgestattet und wird so angesteuert, dass der Deckelabheber bzw. der Rahmenreiniger aus einer von dem Füllloch beabstandeten Ruheposition unter Berücksichtigung der erforderlichen Korrekturen in die Betriebsposition am Füllloch bewegt wird. Der jeweilige Stellhub ist abhängig von den zu korrigierenden Lageabweichungen und kann sich von Füllloch zu Füllloch ändern. Vorzugsweise wird die Korrekturbewegung und die Bewegung des Deckelabhebers/Rahmenreinigers aus der von dem Füllloch beabstandeten Ruheposition in die Betriebsposition jedoch entkoppelt. Die Hubeinrichtungen für den Deckelabheber und den Rahmenreiniger sind in diesem Fall jeweils an einem Laufwagen befestigt, der innerhalb des Tragrahmens des zugeordneten Fahrwerks entlang den Profilen des Tragrahmens verfahrbar ist. Vorzugsweise ist der Laufwagen quer zur Bewegungsrichtung des Tragrahmens verfahrbar, so dass sich die Fahrbewegung des Laufwagens nicht auf die Position des Tragrahmens auswirken kann. Auf die Laufwagen wirken hydraulische Stelleinrichtungen, die an dem zugeordneten Tragrahmen abgestützt sind und den Deckelabheber und den Rahmenreiniger jeweils mit einem fest einstellbaren Stellhub zwischen der Betriebsposition an einem Füllloch und einer von dem Füllloch beabstandeten Ruheposition bewegen. Bei dieser Ausgestaltung sind sämtliche Korrekturbewegungen in X- und Y-Richtung sowie die Fahrbewegung zwischen Ruheposition und Betriebsposition entkoppelt.In the context of the invention, it is that the lifting devices for the Deckelabheber and the frame cleaner are firmly connected to the support frame of the associated chassis. The actuator acting on the support frame is equipped in this case with a path-measuring device and is controlled so that the Deckelabheber or the frame cleaner is moved from a spaced from the filling hole rest position, taking into account the required corrections in the operating position on the filling hole. The respective setting stroke depends on the position deviations to be corrected and can change from filling hole to filling hole. Preferably, however, the correction movement and movement of the lid lift / frame cleaner is decoupled from the rest position spaced from the fill hole to the operative position. The lifting devices for the Deckelabheber and the frame cleaner are in this case respectively attached to a carriage, which is movable within the support frame of the associated chassis along the profiles of the support frame. Preferably, the carriage is movable transversely to the direction of movement of the support frame, so that the driving movement of the carriage can not affect the position of the support frame. On the carriages act hydraulic adjusting devices which are supported on the associated support frame and move the Deckelabheber and the frame cleaner each with a fixed adjustable stroke between the operating position at a filling hole and spaced from the filling hole rest position. In this embodiment, all correction movements in the X and Y directions and the travel movement between the rest position and the operating position are decoupled.
Die Fahrwerke des Deckelabhebers und des Rahmenreinigers weisen vorzugsweise jeweils einen Fahrrahmen auf, wobei die Fahrrahmen räumlich beabstandet und unabhängig voneinander bewegbar sind. Die räumliche Trennung der Fahrwerke erlaubt eine flexible Anpassung an bauliche Gegebenheiten, was vorteilhaft ist, wenn ältere Kokereien mit der erfindungsgemäßen Vorrichtung nachgerüstet werden müssen. Sofern es die baulichen Gegebenheiten zulassen, kann ein gemeinsamer Fahrrahmen für die Fahrwerke verwendet werden. In diesem Fall ergeben sich hinsichtlich der Tragrahmen zwei Alternativen. Gemäß einer ersten Ausführung sind die Tragrahmen für den Deckelabheber und den Rahmenreiniger unabhängig voneinander bewegbar und mittels separater Stellantriebe, die mit Weg- Messeinrichtungen ausgestattet sind, innerhalb des gemeinsamen Fahrrahmens positionierbar. Gemäß einer zweiten alternativen Ausführungsvariante sind der Deckelabheber und der Rahmenreiniger auch an einem gemeinsamen Tragrahmen angeordnet, der mittels eines mit einer Weg- Messeinrichtung ausgestatteten Stellantrieb verfahrbar und exakt positionierbar ist. Die Hubeinrichtungen des Deckelabhebers und des Rahmenreinigers sind bei einer solchen Ausführung an separaten Laufwagen befestigt, die innerhalb des Tragrahmens unabhängig voneinander verfahrbar sind. Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlich erläutert. Die einzige Figur zeigt schematisch eine Vorrichtung an der Unterseite eines nicht dargestellten Kohlefüllwagens zum Abheben von Deckeln 1 aus Fülllochrahmen 2 in der Ofendecke eines Koksofens und zum Reinigen der Fülllochrahmen 2. Zum grundsätzlichen Aufbau dieser Vorrichtung gehören ein Deckelabheber 3, der einen Tragarm 4 mit einem Hubmagnet 5 aufweist, ein Rahmenreiniger 6, der einen Tragarm 4' mit einem Reinigungskopf 7 aufweist sowie Hubeinrichtungen 8, 81 zur Vertikalverstellung der Tragarme 4, 4\ Der Deckelabheber 3 und der Rahmenreiniger 6 sind beidseits einer an der Unterseite des Kohlefüllwagens angeordneten Fülleinrichtung 9 angeordnet, die eine Horizontalförderschnecke 10 sowie ein Füllteleskop 11 umfasst. Der Deckelabheber 3 und der Rahmenreiniger 6 sind jeweils mittels eines Fahrwerks 12, 12' zwischen einer Betriebsposition A, in der der Hubmagnet 5 oder der Reinigungskopf 7 mit einem Füllloch 13 in der Ofendecke des Koksofens fluchtet, und einer von dem Füllloch beabstandeten Ruheposition B horizontal verfahrbar.The chassis of the Deckelabhebers and the frame cleaner preferably each have a traveling frame, wherein the driving frame spaced apart and are movable independently. The spatial separation of the chassis allows flexible adaptation to structural conditions, which is advantageous if older coking plants must be retrofitted with the device according to the invention. If the structural conditions allow, a common chassis for the trolleys can be used. In this case, there are two alternatives with regard to the support frame. According to a first embodiment, the support frame for the Deckelabheber and the frame cleaner are independently movable and positioned by means of separate actuators, which are equipped with path measuring devices within the common driving frame. According to a second alternative embodiment, the lid lifter and the frame cleaner are also arranged on a common support frame, which can be moved and exactly positioned by means of an actuator equipped with a path measuring device. The lifting devices of the Deckelabhebers and the frame cleaner are mounted in such an embodiment of separate carriages, which are independently movable within the support frame.

An den Tragrahmen 16 und den Fahrrahmen 15 sind hydraulische Stelleinrichtungen 20 angeschlossen, die mit Weg-Messeinrichtungen ausgestattet sind. Die hydraulischen Stelleinrichtungen 20 sind an eine Maschinensteuerung des Kohlefüllwagens anschließbar, in der Positionsangaben für die Lage der Fülllöcher 13 in der Ofendecke des Koksofens hinterlegt sind. Alternativ können die hydraulischen Stelleinrichtungen 20 mit einer optischen Messeinrichtung zusammenwirken, welche an dem Kohlfüllwagen angeordnet ist und die Lage der Fülllöcher 13 erfasst. In dem in der Figur dargestellten Ausführungsbeispiel sind die Hubeinrichtungen 8. 81 des Deckelabhebers 3 und des Rahmenreinigers 6 an Laufwagen 21 , 21' befestigt, die innerhalb des Tragrahmens 16 des zugeordneten Fahrwerks 12, 12' entlang den Profilen des Tragrahmens 16 quer zur Bewegungsrichtung des Tragrahmens verfahrbar sind. Auf die Laufwagen 21 , 21' wirken hydraulische Stelleinrichtungen 22, die an den zugeordneten Tragrahmen 16 abgestützt sind und den Deckelabheber 3 und den Rahmenreiniger 6 jeweils mit einem fest einstellbaren Stellhub a, b zwischen der Betriebsposition A an einem Füllloch und einer von dem Füllloch beabstandeten Ruheposition B bewegen.To the support frame 16 and the chassis 15 hydraulic actuators 20 are connected, which are equipped with path-measuring devices. The hydraulic control devices 20 can be connected to a machine control of the coal filling carriage, in which position data for the position of the filling holes 13 are deposited in the furnace roof of the coke oven. Alternatively, the hydraulic actuators 20 may cooperate with an optical measuring device which is arranged on the Kohlfüllwagen and detects the position of the filling holes 13. In the embodiment shown in the figure, the lifting devices 8. 8 1 of Deckelabhebers 3 and the frame cleaner 6 are attached to carriage 21, 21 ', within the support frame 16 of the associated chassis 12, 12' along the profiles of the support frame 16 transverse to the direction of movement of the support frame are movable. On the carriages 21, 21 'act hydraulic adjusting means 22 which are supported on the associated support frame 16 and the Deckelabheber 3 and the frame cleaner 6 each with a fixed adjustable stroke a, b between the operating position A at a filling hole and a spaced from the filling hole rest position B move ,
In dem Ausführungsbeispiel weisen die Fahrwerke12, 12' für den Deckelabheber 3 und den Rahmenreiniger 6 jeweils einen Fahrrahmen auf, wobei die Fahrrahmen räumlich beabstandet und unabhängig voneinander bewegbar sind. Sofern es die baulichen Gegebenheiten zulassen, können die Fahrwerke 12, 12' auch einen gemeinsamen Fahrrahmen aufweisen, in dem die Tragrahmen16 für den Deckelabheber und den Rahmenreiniger angeordnet und quer zur Bewegungsrichtung des Fahrrahmens verschiebbar sind.In the exemplary embodiment, the chassis 12, 12 'for the Deckelabheber 3 and the frame cleaner 6 each have a traveling frame, wherein the driving frame spaced apart and are movable independently. If the structural conditions permit, the running gears 12, 12 'can also have a common traveling frame, in which the supporting frames 16 for the lid lifter and the frame cleaner are arranged and displaceable transversely to the direction of movement of the traveling frame.
Die erfindungsgemäße Vorrichtung ermöglicht eine präzise Ausrichtung des Deckelabhebers 3 und des Rahmenreinigers 6 an den Fülllöchern in der Ofendecke eines Koksofens und ist in der Lage, betrieblich bedingte Lageabweichungen der Fülllöcher 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 der Fülllochrahmen 2 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 Fülllöcher zur Befüllung einer Ofenkammer an einer vorgegebenen Stelle, die dem Füllloch 13 zugeordnet ist, positioniert. Anschließend werden der Deckelabheber und der Rahmenreiniger 6 aus einer von dem Füllloch beabstandeten Ruheposition B in eine dem Füllloch benachbarten Betriebsposition A bewegt und mit Hilfe zweiachsiger Ausgleichsbewegungen des Fahrwerks 12, 12' so positioniert, dass der Hubmagnet 5 des Deckelabhebers 3 bzw. der Reinigungskopf 7 des Rahmenreinigers 6 mittig zentriert zum Deckel/Fülllochrahmen ausgerichtet sind. In einem ersten Schritt wird der Hubmagnet 5 auf den Fülllochdeckel abgesenkt und aktiviert. Der Fülllochdeckel wird aus dem Füllloch 13 ausgehoben und in die Ruheposition B gefahren. Im nächsten Schritt wird der Reinigungskopf 7 des Rahmenreinigers 6 in den Fülllochrahmen 2 abgesenkt und der Fülllochrahmen gereinigt. Nachdem die Reinigung beendet ist und der Rahmenreiniger 6 in seine Ruheposition zurückgefahren worden ist, wird das Füllteleskop 11 abgesenkt und die Koksofenkammer mit Einsatzkohle befüllt. Nach Beendigung des Befüllvorganges und nach dem Wiedereinsetzen des Fülllochdeckels durch den Deckelabheber werden die Fahrrahmen 15 der Fahrwerke 12, 12' wieder in ihre Ausgangslage zurückbewegt, wobei dieser Vorgang während der Fahrt des Kohlefüllwagens zum Kohleturm erfolgen kann. Der Deckelabheber und der Rahmenreiniger stehen nunmehr wieder bereit für eine Neuverstellung an der nächsten zu befüllenden Ofenkammer. The device according to the invention allows a precise alignment of the Deckelabhebers 3 and the frame cleaner 6 at the filling holes in the furnace roof of a coke oven and is able to compensate for operational positional deviations of the filling holes from a predetermined basic position in the X and Y directions. In 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 of the Fülllochrahmen 2 are measured in the longitudinal and transverse directions and stored for each Fülllochrahmen in a machine control on the coal filling 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 holes for filling a furnace chamber at a predetermined location, which is associated with the filling hole 13, positioned. Subsequently, the cap lifter and the frame cleaner 6 are moved from a rest position B spaced from the filling hole to an operating position A adjacent the filling hole, and by means of biaxial Balancing movements of the chassis 12, 12 'positioned so that the solenoid 5 of the Deckelabhebers 3 and the cleaning head 7 of the frame cleaner 6 are centered centered to cover / Fülllochrahmen aligned. In a first step, the solenoid 5 is lowered onto the Fülllochdeckel and activated. The filling hole cover is lifted out of the filling hole 13 and moved to the rest position B. In the next step, the cleaning head 7 of the frame cleaner 6 is lowered into the Fülllochrahmen 2 and the Fülllochrahmen cleaned. After the cleaning is completed and the frame cleaner 6 has been moved back to its rest position, the filling telescope 11 is lowered and the coke oven chamber filled with feed coal. After completion of the filling and after the replacement of the Fülllochdeckels by Deckelabheber the travel frame 15 of the chassis 12, 12 'moved back to their original position, this process can be done while driving the coal filling car to the coal tower. The Deckelabheber and the frame cleaner are now ready for a readjustment to the next furnace chamber to be filled.
