    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 Füllochdeckeln 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 fill hole lids 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.

    Bei einem aus DE-A 25 45 265 bekannten Kohlefüllwaren ist der Schneckenförderer mit einer geneigt angeordneten Förderschnecke schwenkbeweglich an einem an der Unterseite des Kohlefüllwagens verfahrbaren Träger aufgehängt. Das Gehäuse des Schneckenförderers ist ausreichend hoch ausgebildet, so daß sich innerhalb des Schneckenförderergehäuses ein Schüttkegel ausbilden kann. Die Anordnung erfordert ebenfalls eine große Einbauhöhe an der Unterseite des Kohlefüllwagens, die nicht immer zur Verfügung steht.In a coal filling product known from DE-A 25 45 265 the screw conveyor with an inclined arrangement Screw conveyor swiveling on one of the bottom suspended from the coal filling vehicle movable carrier. The The screw conveyor housing is sufficiently high trained so that is inside the screw conveyor housing can form a cone. The order also requires a large installation height at the bottom of the coal filling truck, which is not always available.

    Die Aufgabe wird bei dem eingangs beschriebenen Kohlefüllwagen erfindungsgemäß dadurch gelöst, daß das Gehäuse des Schneckenförderers an der Unterseite des Kohlefüllwagens horizontal beweglich angeordnet sowie mittels eines Stellantriebs 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, wobei das Gehäuse des Schneckenförderers eine oberseitige Abdeckplatte aufweist, die in der Ausgangsstellung des Schneckenförderers den Bodenauslaß des Kohlefüllwagens so weit verschließt, daß keine Kohle auf die Decke der Verkokungskammern auslaufen kann. Der Schneckenförderer ist in Fahrtrichtung des Kohlefüllwagens ausgerichtet, wobei die Stellbewegung des Schneckenförderers in Form einer Axialbewegung in Längsrichtung des Schneckenförderers erfolgt. 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. Die Abdeckplatte des Schneckenförderers erfüllt die Funktion eines Schiebers, der den Bodenauslaß des Kohlefüllwagens verschließt und den Bodenauslaß nur freigibt, wenn die Befüllung einer Verkokungskammer erfolgt und der Schneckenförderer sich in der entsprechenden Füllstellung befindet.The task is described in the beginning Coal filling truck solved according to the invention in that the Housing of the screw conveyor at the bottom of the Coal filling truck arranged horizontally movable as well by means of an actuator with the location of the Charging car between a starting position, in which the outlet port is offset to the side of the fill hole is positioned, and a filling position in which the Outlet port is essentially aligned with the fill hole, is movable, the housing of the screw conveyor a Has top cover plate, which in the Starting position of the screw conveyor the bottom outlet of the Coal filling car closes so far that no coal on the coking chamber ceiling can leak. The Screw conveyor is in the direction of travel of the coal filling car aligned, the adjusting movement of the screw conveyor in the form of an axial movement in the longitudinal direction of the Screw conveyor takes place. The travel of the screw conveyor housing is set up so that in a first Working position (starting position) of the fill hole cover is free is accessible for the lid lifting device and at unchanged location of the coal filling truck in a second Working position (filling position) of the outlet nozzle in essentially aligned with the fill hole.
