Description

Die Erfindung betrifft eine Einrichtung zum Abheben und Aufsetzen der Füllochdeckel an Horizontalkammer-Verkokungsöfen und zum Reinigen der Dichtflächen zur Verwendung am Füllwagen, an dem die Einrichtung hebund senkbar angeordnet ist, mit einem drehbaren Magnetgreifer zum Erfassen und Halten des Deckels und mit einem Füllochrahmenreiniger mit einem rotierenden Reinigungswerkzeug, der aus einer Ruhestellung in die Reinigungsstellung und umgekehrt bewegbar ist.The invention relates to a device for lifting and placing the Füllochdeckel on horizontal chamber coking ovens and for cleaning the sealing surfaces for use on the filling truck, on which the device is arranged in a lowerable manner, with a rotatable magnetic gripper for gripping and holding the lid and with a Füllochrahmenreiniger with a rotating cleaning tool that can be moved from a rest position into the cleaning position and vice versa.

Es ist bekannt, an Horizontal-Verkokungsöfen das Öffnen, Schließen und Reinigen der Füllöcher mit einer geeigneten Vorrichtung maschinell durchzuführen. Die DE-A-30 16 418 zeigt eine Vorrichtung dieser Art, die verhältnismäßig aufwendig ausgebildet ist und dementsprechend einen sehr umfangreichen Raum zur Installation sowie zu ihren Betrieb erfordert. Sie ist unabhängig vom Füllwagen und anderen Einrichtungen oberhalb der Ofendecke an einem Traggerüst verfahrbar. Dies führt neben der Beanspruchung zusätzlichen Freiraumes zugleich zu einer Versperrung der Zugangswege oberhalb der Ofendecke. Für den praktischen Betrieb ist dies sehr nachteilig, weil gerade die zusätzliche,lnstallation von empfindlichen Maschinen und Geräten im hitzegefährdeten Bereich für Wartungs- und Reparaturarbeiten einen schnellen Zugriff erfordert.It is known to carry out the opening, closing and cleaning of the filling holes mechanically on a horizontal coking furnace with a suitable device. DE-A-30 16 418 shows a device of this type, which is relatively complex and accordingly requires a very large space for installation and operation. It can be moved on a supporting frame independent of the filling truck and other devices above the furnace ceiling. In addition to taking up additional space, this also blocks the access routes above the furnace ceiling. This is very disadvantageous for practical operation, because the additional, installation of sensitive machines and devices in the heat-endangered area requires quick access for maintenance and repair work.

Die Erfindung verfolgt das Ziel, die einzelnen Funktionen wie das Abheben und Aufsetzen des Füllochdeckels und das Reinigen der Dichtflächen auf einfache und auf engstem Raum durchführbare Bewegungsabläufe zurückzuführen, so daß sich diese Funktionen mit einer Einrichtung in kompakter Bauweise unter Verwendung betriebssicherer Geräte und Bauteile ausführen lassen, die gut zugänglich sind und somit Wartungs-und Reparaturarbeiten schnell und problemlos ausgeführt werden können. Weiter soll die Einrichtung so ausgebildet sein, daß sie ohne Schwierigkeiten am Füllwagen installiert werden kann und mit diesem oberhalb der Ofendecke verfahrbar ist.The invention aims to attribute the individual functions such as lifting and putting on the fill hole cover and cleaning the sealing surfaces to simple and feasible movement sequences, so that these functions can be carried out with a device in a compact design using reliable devices and components that are easily accessible and therefore maintenance and repair work can be carried out quickly and easily. Furthermore, the device should be designed so that it can be installed on the filling car without difficulty and can be moved with it above the furnace ceiling.

Diese Aufgabe wird bei einer Einrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß Magnetgreifer und Füllochrahmenreiniger an einem Schwenkkopf auf entgegengesetzten Seiten der Schwenkachse mit in einer Ebene winklig zueinander stehenden Drehachsen angeordnet sind, wobei die Schwenkachse des Schwenkkopfes in dieser Ebene liegt und mit der Winkelhalbierenden des von den beiden Drehachsen gebildeten Winkels zusammenfällt, und daß der Schwenkkopf an einem Tragteil gelagert ist, der an einer senkrechten Führung höhenverstellbar geführt ist.This object is achieved according to the invention in a device of the type mentioned at the outset in that magnetic grippers and filler frame cleaners are arranged on a swivel head on opposite sides of the swivel axis with axes of rotation which are at an angle to one another in one plane, the swivel axis of the swivel head lying in this plane and with the bisector of the angle of the angle formed by the two axes of rotation coincides, and that the swivel head is mounted on a supporting part which is guided in a vertically adjustable manner on a vertical guide.

Der Winkel zwischen den beiden Drehachsen beträgt vorzugsweise 90°. Weiter ist es vorteilhaft, den Schwenkkopf im wesentlichen als Querträger mit etwa trogförmigem Profil auszubilden, wobei Magnetgreifer und Füllochrahmenreiniger an den äußeren Schenkeln derart angeordnet sind, daß der Greifer einerseits und das Reinigungswerkzeug andererseits jeweils an den Außenseiten der Schenkeln sich befinden.The angle between the two axes of rotation is preferably 90 °. It is also advantageous to design the swivel head essentially as a cross member with an approximately trough-shaped profile, magnetic grippers and Fülloch frame cleaners being arranged on the outer legs in such a way that the gripper on the one hand and the cleaning tool on the other are located on the outer sides of the legs.

Für die Reinigung der Dichtflächen des Füllochdeckels ist in weiterer Ausgestaltung der Erfindung am Tragteil ein auf die Drechachse des in Ruhestellung befindlichen Magnetgreifers zentriertes Reinigungselement an einem in Richtung der Drehachse des Magnetgreifers hin- und herbewegbaren Schlitten angeordnet.In a further embodiment of the invention, for cleaning the sealing surfaces of the filling hole cover, a cleaning element centered on the axis of rotation of the magnetic gripper in the rest position is arranged on a carriage that can be moved back and forth in the direction of the axis of rotation of the magnetic gripper.

Für die beiden rotierenden Elemente wie Magnetgreifer und Füllochrahmenreiniger können zwei Einzelantriebe oder ein gemeinsamer Antrieb über ein Getriebe vorgesehen sein.For the two rotating elements such as magnetic gripper and Füllochrahmenreiniger two individual drives or a common drive via a gear can be provided.

Nach einer anderen Weiterbildung der Erfindung ist vorgesehen, daß der Füllochrahmenreiniger mit einem rotierend arbeitenden Werkzeug, beispielsweise in Form von Bürsten oder Schabern, zum Reinigen des Füllschachtes kombiniert ist.According to another development of the invention, it is provided that the Füllochrahmenreiniger is combined with a rotating tool, for example in the form of brushes or scrapers, for cleaning the filling shaft.

Ein Hauptvorteil der Erfindung ist darin zu sehen, daß Magnetgreifer und Füllochrahmenreiniger, also die Elemente, die wechselweise in einer Arbeitsstellung zentrisch zum jeweiligen Fülloch zu positionieren sind, an einem gemeinsamen Schwenkkopf angeordnet sind, womit die Möglichkeit gegeben ist, die erforderlichen Arbeitsbewegungen durch einfache Drehbewegungen auszuführen. Damit ist zugleich eine räumlich eng benachbarte Anordnung dieser beiden Elemente gegeben. Dies führt zu einer kompakten Bauweise und hat außerdem den Vorteil, daß für die Arbeitsbewegungen der Elemente relativ wenig Raum beansprucht wird.A main advantage of the invention can be seen in the fact that the magnetic gripper and filling hole frame cleaner, i.e. the elements which are to be positioned alternately in a working position centrally to the respective filling hole, are arranged on a common swivel head, which makes it possible to perform the required working movements by simple rotary movements to execute. This results in a spatially closely adjacent arrangement of these two elements. This leads to a compact design and also has the advantage that relatively little space is required for the working movements of the elements.

Als weiterer Vorteil ist zu erwähnen, daß während der Ausführung der Reinigung der Dichtflächen des Füllochs zugleich der Füllochdeckel an seinen Dichtflächen gereinigt werden kann. Hierzu ist ein weiteres Reinigungselement vorgesehen, welches an einem Schlitten angeordnet ist und eine geradlinige Arbeitsbewegung ausführt. Dieser Schlitten ist zusammen mit dem Schwenkkopf an ein und demselben Tragteil gelagert, so daß eine zusätzliche Ausrichtung zwischen Füllochdeckel und Reinigungselement entfällt. Der rotierende Füllochrahmenreiniger kann mit einem weiteren Werkzeug zum Reinigen des Füllschachtes kombiniert sein..As a further advantage, it should be mentioned that while the sealing surfaces of the filling hole are being cleaned, the filling hole cover on its sealing surfaces can also be cleaned. For this purpose, a further cleaning element is provided, which is arranged on a carriage and carries out a linear working movement. This slide is mounted together with the swivel head on one and the same supporting part, so that an additional alignment between the fill hole cover and the cleaning element is not necessary. The rotating Füllochrahmenreiniger can be combined with another tool for cleaning the filling shaft.

In der Zeichnung ist die Ofendecke 1 eines Verkokungsofens in einem Querschnitt in der Mittenebene eines Füllochs 2 dargestellt. Den oberen Abschluß des Fülllochs 2 bildet der kreisrunde Füllochrahmen 3, der zur Lagerung des Füllochdeckels 4 dient. Die Dichtfläche 5 des Füllochrahmens und ebenso die korrespondierende Dichtfläche 6 des Füllochdeckels 4 sind als Kegelflächen ausgebildet.In the drawing, the furnace top 1 of a coking furnace is shown in a cross section in the center plane of a filling hole 2. The upper end of the fill hole 2 is formed by the circular fill hole frame 3, which is used to support the fill hole cover 4. The sealing surface 5 of the Füllochrahmen and also the corresponding sealing surface 6 of the Füllochdeckels 4 are designed as conical surfaces.

Oberhalb der Ofendecke 1 ist in Längsrichtung der Ofenbatterie ein nicht dargestellter Füllwagen auf Schienen verfahrbar, der beim Füllen einer Kammer eine solche Stellung einnimmt, daß die Kohle über einen Einfülltrichter in das darunter liegende geöffnete Fülloch einfließen kann. Das Abheben und spätere Aufsetzen des Füllochdeckels wird maschinell mit der nachstehend näher beschriebenen Einrichtung ausgeführt.Above the furnace ceiling 1 in the longitudinal direction of the furnace battery, a filling carriage, not shown, can be moved on rails, which, when filling a chamber, assumes such a position that the coal can flow into the open filling hole underneath via a filling funnel. The lifting and later putting on of the filling hole cover is carried out mechanically with the device described in more detail below.

Die Einrichtung ist an einem senkrecht verlaufenden Traggerüst, welches an seinem oberen Ende mit der Rahmenkonstruktion des Füllwagens fest verbunden ist, höhenverstellbar geführt. Gebildet wird das Traggerüst im wesentlichen aus zwei mit ihren offenen Seiten einander zugewandten U-Profilen 7, deren Schenkel als Führungsschienen für die Laufrollen 8 eines Tragteils 9 dienen. Der Tragteil 9 setzt sich zusammen aus einem waagerecht verlaufenden Hauptteil 10, der mit seinem rückwärtigen Ende die U-Profile 7 durchdringt und einem darüber liegenden Aufsatzteil 11. Von den insgesamt vier Führungsrollen ist ein Paar Führungsrollen am Hauptteil 10 und das zweite Paar Führungsrollen am Aufsatzteil 11 jeweils an einer waagerecht verlaufenden Achse drehbar gelagert. Das Heben und Senken des Tragteils 9 wird mit einem nicht dargestellten Antrieb bewirkt, der aus einem hydraulisch oder pneumatisch betriebenen Hubzylinder oder einem Elektromotor mit einem Getriebeteil zur Erzeugung einer Linearbewegung bestehen kann.The device is vertically adjustable on a vertically extending supporting frame, which is firmly connected at its upper end to the frame structure of the filling truck. The supporting structure is essentially formed from two U-profiles 7 facing one another with their open sides, the legs of which serve as guide rails for the rollers 8 of a supporting part 9. The support part 9 is composed of a horizontal main part 10, which penetrates with its rear end through the U-profiles 7 and an overlying attachment part 11. Of the total of four guide rollers, a pair of guide rollers on the main part 10 and the second pair of guide rollers on the attachment part 11 each rotatably mounted on a horizontal axis. The lifting and lowering of the support part 9 is effected with a drive, not shown, which can consist of a hydraulically or pneumatically operated lifting cylinder or an electric motor with a gear part for generating a linear movement.

Wie die Darstellung in Fig. 3 zeigt, ist das Traggerüst von einem Schutzkasten 12 umgeben, der an den Außenseiten der U-Profile 7 anliegt, an einer Seite für die Auf- und Abbewegung des Tragteils 9 offen ist und an den drei anderen Seiten den Innenraum dicht umschließt.As shown in Fig. 3, the support structure is surrounded by a protective box 12 which bears on the outer sides of the U-profiles 7, is open on one side for the up and down movement of the support member 9 and the other three sides Tightly encloses the interior.

Am freien Ende des vorkragenden Hauptteils 10 ist ein Schwenkkopf 13 an einer aus dem Hauptteil 10 austretenden Schwenkwelle 14 gelagert, deren Schwenkachse 15 in einer senkrechten Querebene zur Längsachse der Ofenbatterie mit einer Neigung von 45° zur Horizontalen verläuft.At the free end of the projecting main part 10, a swivel head 13 is mounted on a swivel shaft 14 emerging from the main part 10, the swivel axis 15 of which runs in a perpendicular transverse plane to the longitudinal axis of the furnace battery with an inclination of 45 ° to the horizontal.

Der Schwenkkopf 13 ist im wesentlichen als Querträger mit etwa trogförmigen Profil ausgebildet, wobei die beiden gleichlangen Schenkel 16, 17 an den Enden des Mittelteils - der den Boden des Trogs bildet - mit einer Neigung von 45° starr befestigt sind, so daß die beiden Schenkel 16 und 17 rechtwinklig zueinander stehen. Der Schenkel 17 bildet den Halter für einen an sich bekannten drehbaren Magnetgreifer 18 zum Erfassen und Halten des Füllochdeckels 4. Dieser Magnetgreifer befindet sich auf der Außenseite des Schenkels 16 und wird von einem auf der Innenseite angeflanschten Einzelantrieb 19, z. B. ein Elektromotor mit zugehörigem Untersetzungsgetriebe, angetrieben.The swivel head 13 is essentially designed as a cross member with an approximately trough-shaped profile, the two legs 16, 17 of equal length being rigidly attached to the ends of the central part - which forms the bottom of the trough - at an inclination of 45 °, so that the two legs 16 and 17 are perpendicular to each other. The leg 17 forms the holder for a known rotatable magnetic gripper 18 for gripping and holding the filling hole cover 4. This magnetic gripper is located on the outside of the leg 16 and is driven by a single drive 19 flanged on the inside, e.g. B. driven an electric motor with associated reduction gear.

Der andere Schenkel 17 des Schwenkkopfes 13 dient zum Halten eines rotierenden Werkzeugs 20 zum Reinigen der Sitzfläche des Füllochrahmens 3. Auf der Innenseite des Schenkels 17 ist in gleicher Weise wie bei dem Schenkel 16 ein Einzelantrieb 21 angeflanscht, der die Drehenergie für das Reinigungswerkzeug 20 liefert.The other leg 17 of the swivel head 13 serves to hold a rotating tool 20 for cleaning the seat surface of the filling hole frame 3. On the inside of the leg 17, in the same way as for the leg 16, an individual drive 21 is flanged, which supplies the rotational energy for the cleaning tool 20 .

In dem Aufsatzteil 11 ist ein in horizontaler Richtung verfahrbarer Schlitten 22 angeordnet, der an der dem Schwenkkopf 13 zugewandten Stirnseite ein Reinigungswerkzeug 23 trägt, bei dem es sich beispielsweise um ein aus Bürsten oder mechanischen Schabern gebildetes Element zum Reinigen der Dichtfläche des Füllochdeckels 4 handeln kann. Während des Reinigungsvorgangs wird der Füllochdeckel 4 durch den Antrieb 19 in Rotation versetzt und das Reinigungswerkzeug 23 mit Hilfe des Schlittens 22 an die zu reinigende Dichtfläche gedrückt, nachdem der Schwenkkopf 13 vorher mit dem abgenommenen Füllochdeckel 4 in die Reinigungsstellung geschwenkt worden ist.Arranged in the top part 11 is a carriage 22 which can be moved in the horizontal direction and which carries a cleaning tool 23 on the end face facing the swivel head 13, which can be an element made of brushes or mechanical scrapers for cleaning the sealing surface of the filling hole cover 4 . During the cleaning process, the fill hole cover 4 is set in rotation by the drive 19 and the cleaning tool 23 is pressed against the sealing surface to be cleaned by means of the slide 22 after the swivel head 13 has previously been pivoted into the cleaning position with the removed fill hole cover 4.

Eine hinsichtlich der Antriebe für den Magnetgreifer 18 und den Füllochrahmenreiniger 20 abgewandelte Ausführungsform ist in Fig. 2 dar= gestellt. Hier stehen diese beiden Elemente über ein im Innern des Schwenkkopfes 13a befindliches Getriebe mit einem zentralen Antrieb in Verbindung, der im Schwenkkopf 13a oder auch im Tragteil 9 eingebaut sein kann.An embodiment modified with regard to the drives for the magnetic gripper 18 and the filling hole frame cleaner 20 is shown in FIG. 2. Here, these two elements are connected via a gear located inside the swivel head 13a to a central drive, which can be installed in the swivel head 13a or in the support part 9.

Der Füllochrahmenreiniger 20 kann auch mit einem weiteren Werkzeug 24, z. B. in Form einer zylindrischen Bürste, zum Reinigen des Füllschachtes unterhalb des Füllochrahmens 3 bestückt sein (Fig. 5). Mit einem solchen Werkzeug können Füllochrahmen 3 und Füllschacht in einem Arbeitsgang gereinigt werden.The Füllochrahmenreiniger 20 can also with another tool 24, z. B. in the form of a cylindrical brush, for cleaning the filling shaft below the Füllochrahmens 3 (Fig. 5). With such a tool, filling hole frame 3 and filling shaft can be cleaned in one operation.

Die Funktionsweise der Einrichtung ist wie folgt :

  • - die Einrichtung hat die Reinigungsposition oberhalb eines Füllochs 2 eingenommen,
  • - durch Abwärtsbewegung des Tragteils 9 wird der Magnetgreifer 18 bis auf den Füllochdeckel 4 abgesenkt,
  • - Magnet wird eingeschaltet und Füllochdeckel 4 mit Hilfe des Antriebs 19 gedreht,
  • - Tragteil 9 fährt nach oben,
