Vorzugsweise ist die Stellung der Fräseinrichtung an verschiedene Neigungswinkel anpaßbar, so daß es mit einer Koksofenbedienungseinrichtung der erfindungsgemäßen Art möglich ist, Türstopfen mit unterschiedlich geneigten Seitenwänden zu reinigen. Grundsätzlich ist es jedoch auch möglich, daß für jede Türstopfenform eine Koksofenbedienungseinrichtung vorgesehen ist, die eine entsprechend der Neigung der Seitenwand des Türstopfens angestellte Fräseinrichtung aufweist.The position of the milling device is preferably adapted to the inclination of the side wall of the door stopper. Preferably, the position of the milling device can be adapted to different angles of inclination, so that it is possible with a coke oven operating device of the type according to the invention to clean door stoppers with differently inclined side walls. In principle, however, it is also possible that a Koksofenbedienungseinrichtung is provided for each door plug shape, which has a corresponding to the inclination of the side wall of the door plug employed Fräseinrichtung.

Zur Steuerung der Vorschubbewegung der Fräseinrichtung relativ zum Türstopfen kann eine Steuereinrichtung vorgesehen sein. Die Steuereinrichtung kann eine entsprechende Sensorik aufweisen, um ausgehend von einer Nullstellung die Fräseinrichtung in vorgegebenen Vorschubschritten in Richtung auf die Seitenwand oder die Sockelfläche des Türstopfens zu verfahren. Die Steuereinrichtung ist mit einer Antriebseinheit gekoppelt, die den Vorschub der Fräseinrichtung bewirkt. Beispielsweise kann die Fräseinrichtung auf einem Werkzeugschlitten angeordnet sein, der über einen Hydraulikzylinder bewegt wird. Bei einer besonders einfachen Ausführungsform kann die Schnittiefe durch Futterbleche eingestellt werden.For controlling the advancing movement of the milling device relative to the door stop, a control device may be provided. The control device may have a corresponding sensor to move from a zero position, the milling device in predetermined feed steps in the direction of the side wall or the base surface of the door stopper. The control device is coupled to a drive unit which effects the advance of the milling device.

At the upper end of the holding frame, the longitudinal members of the holding frame can be connected via cross members with the side wall of the coke oven, so that there is a stable connection of the holding frame to the coke oven.

Sind auf beiden Seiten des Koksofens Koksofenbedienungseinrichtungen der erfindungsgemäßen Art vorgesehen, kann zur Absaugung der bei der Türstopfenreinigung freigesetzten Emissionen eine die Koksofenbedienungseinrichtungen zumindest beim Reinigungsvorgang der Türstopfen im wesentlichen vollständig gegenüber der Umgebung abschließende gemeinsame Einhausung vorgesehen sein. Die gemeinsame Einhausung kann sich im wesentlichen von der Seite der Koksausdrückmaschine über die gesamte Breite des Koksofens bis zur Seite der Koksüberleitmaschine erstrecken. Die gemeinsame Einhausung stellt sicher, daß es im Zusammenhang mit der Türstopfenreinigung zu keinem Übertritt von Schadstoffen aus dem Reinigungsbereich in die Umgebung kommen kann.If coke oven operating devices of the type according to the invention are provided on both sides of the coke oven, a common housing can be provided for extracting the emissions released during the door stopper cleaning, at least during the cleaning process of the door plugs substantially completely against the environment. The common housing may extend substantially from the side of the coke ejector over the entire width of the coke oven to the side of the coke transfer machine. The common enclosure ensures that in connection with the door plug cleaning, no transfer of pollutants from the cleaning area into the environment can occur.

Zusätzlich zu der gemeinsamen Einhausung kann vorgesehen sein, daß jede Koksofenbedienungseinrichtung als solche ebenfalls eingehaust ist. Durch die doppelte Einhausung der Koksofenbedienungseinrichtungen wird sichergestellt, daß kein Übertritt von Emissionen, die beim Reinigungsvorgang freigesetzt werden, in die Umgebung befürchtet werden muß, und zwar auch dann nicht, wenn die "innere" oder die' gemeinsame Einhausung während des Reinigungsvorgangs eines Türstopfens beispielsweise aufgrund eines Störzustandes geöffnet werden muß. Insbesondere ist es dem Kokereibedienungspersonal möglich, innerhalb der gemeinsamen Einhausung die innere Einhausung einer Koksofenbedienungseinrichtung zu öffnen, um beispielsweise eine notwendige Reparatur während eines Reinigungsvorgangs ausführen zu können. Für jede Koksofenbedienungseinrichtung kann eine Absaugeinrichtung vorgesehen sein, wobei die Absaugeinrichtungen an eine Sammelleitung angeschlossen sein können. Über die Sammelleitung ist dann die gemeinsame Ableitung der beim Reinigungsvorgang der Türstopfen freigesetzten Emissionen möglich.In addition to the common housing can be provided that each coke oven operation device is also enclosed as such. The double enclosure of the coke oven controls ensures that no leakage of emissions released during the cleaning process into the environment must be feared, even if the "inner" or the common enclosure during the cleaning process of a door plug, for example must be opened due to a fault condition. In particular, it is possible for coke oven operators to open the inner housing of a coke oven operating device within the common housing, in order, for example, to be able to carry out a necessary repair during a cleaning process. For each coke oven operating device, a suction device may be provided, wherein the suction devices may be connected to a manifold. About the manifold then the common derivation of the released during the cleaning process of the door plug emissions is possible.

Zum Einsetzen und Herausnehmen einer Ofentür in die bzw. aus einer Türöffnung der Verkokungskammer und zum Einsetzen und Herausnehmen der Ofentür in den bzw. aus dem Halterahmen kann eine Türhebeeinrichtung der Koksausdrückmaschine und/oder der Koksüberleitmaschine vorgesehen sein. Dadurch wird der Reinigungsvorgang der Ofentür vereinfacht. Grundsätzlich läßt es die Erfindung jedoch bedarfsweise auch zu, daß eine in Längsrichtung des Koksofens und von den Koksofenbedienungsmaschinen unabhängig verfahrbare Türhebeeinrichtung vorgesehen ist.For inserting and removing an oven door into and out of a door opening of the coking chamber and for inserting and removing the oven door into or out of the holding frame, a door lifting device of the coke ejecting machine and / or the coke transfer machine may be provided. This simplifies the cleaning process of the oven door. In principle, however, the invention also makes it possible, if necessary, for a door lifting device, which can be moved independently in the longitudinal direction of the coke oven and by the coke oven operating machines, to be provided.
