    Der Kohlefüllwagen ist schienengeführt auf der Decke der Verkokungskammern einer Koksofenbatterie verfahrbar. Er nimmt Einsatzkohle von einem Kohleturm auf und transportiert sie zu den Verkokungskammern, in welche sie durch Füllöcher eingefüllt wird. Moderne Kohlefüllwagen weisen ein Zwangsbeschickungssystem mit einem horizontalen Schneckenförderer unterhalb des Bodenauslasses auf. Ferner sind sie mit einer automatischen Deckelabhebevorrichtung zum Öffnen und Verschließen von Fullochdeckeln sowie mit einem Teleskoprohr, welches den Auslaßstutzen des Schneckenförderers mit dem geöffneten Fülloch verbindet, zur Vermeidung störender Emissionen während des Füllvorganges ausgerüstet. Die beschriebenen Einrichtungen erfordern eine große Einbauhöhe an der Unterseite des Kohlefüllwagens. Die örtlichen Verhältnisse bestehender Kokereianlagen lassen den Einsatz moderner Kohlefüllwagen mit den beschriebenen Einrichtungen oftmals nicht zu.The coal filling truck is guided on the ceiling of the Coking chambers of a coke oven battery can be moved. He picks up coal from a coal tower and transports it them to the coking chambers into which they go through Filling holes is filled. Modern coal filling trucks show a forced feed system with a horizontal Screw conveyor below the floor outlet. Further they are with an automatic lid lifting device for opening and closing Fulloch covers as well as with a telescopic tube, which the outlet of the Screw conveyor connects to the open filling hole, to avoid disturbing emissions during the filling process equipped. The facilities described require a large installation height on the underside of the coal filling car. The local conditions of existing coking plants allow the use of modern coal filling trucks with the described facilities often too.

    Der Erfindung liegt die Aufgabe zugrunde, einen Kohlefüllwagen des eingangs beschriebenen Aufbaus anzugeben, der sich durch eine niedrige Einbauhöhe für den Schneckenförderer sowie die Deckelabhebevorrichtung auszeichnet.The invention has for its object a coal filling truck of the structure described at the beginning, the low installation height for the screw conveyor and distinguishes the lid lifting device.

    Zur Lösung dieser Aufgabe lehrt die Erfindung, daß das Gehäuse des Schneckenförderers an der Unterseite des Kohlefüllwagens horizontal beweglich angeordnet sowie mittels eines Stellantriebes bei unverändertem Standort des Kohlefüllwagens zwischen einer Ausgangsstellung, in welcher der Auslaßstutzen seitlich zum Fülloch versetzt positioniert ist, und einer Füllstellung, in welcher der Auslaßstutzen im wesentlichen mit dem Fülloch fluchtet, bewegbar ist. Gemäß einer für die Praxis bevorzugten Ausführung ist der Schneckenförderer in Fahrtrichtung des Kohlefüllwagens ausgerichtet und erfolgt die Stellbewegung des Schneckenförderers in Form einer Axialbewegung in Längsrichtung des Schneckenförderers. Der Stellweg des Schneckenförderergehäuses ist so eingerichtet, daß in einer ersten Arbeitsstellung (Ausgangsstellung) der Füllochdeckel frei zugänglich ist für die Deckelabhebevorrichtung und bei unverändertem Standort des Kohlefüllwagens in einer zweiten Arbeitsstellung (Füllstellung) der Auslaßstutzen im wesentlichen mit dem Fülloch fluchtet. Die erfindungsgemäße Anordnung ermöglicht es, den Auslaßstutzen so tief anzuordnen, daß durch das Teleskoprohr während des Befüllvorganges nur ein kleiner Abstand überbrückt werden muß. Das Teleskoprohr ist folglich mit sehr kurzer Baulänge ausführbar. Zusatzaggregate zur Betätigung des Teleskoprohres sind entsprechend ebenfalls als kompakte Aggregate ausführbar.To achieve this object, the invention teaches that Casing of the screw conveyor on the underside of the coal filling truck horizontally movable and by means of an actuator with unchanged location of the coal filling car between a starting position in which the Exhaust port positioned laterally to the filling hole and a filling position in which the outlet port essentially aligned with the fill hole, is movable. According to a preferred embodiment in practice, the Screw conveyor aligned in the direction of travel of the coal filling car and the adjusting movement of the screw conveyor takes place in the form of an axial movement in the longitudinal direction of the Screw conveyor. The travel of the screw conveyor housing is set up in a first working position (Starting position) the fill hole cover is freely accessible is for the lid lifting device and with unchanged Location of the coal filling truck in a second Working position (filling position) of the outlet connection essentially aligned with the fill hole. The arrangement according to the invention makes it possible to arrange the outlet nozzle so deep that through the telescopic tube during the filling process only a small distance has to be bridged. The telescopic tube can therefore be implemented with a very short overall length. Additional units for actuating the telescopic tube are corresponding also available as compact units.
