Description

Die Erfindung richtet sich auf eine Spülstein-Handhabungsvorrichtung, die außenseitig am Gefäßboden eines metallurgischen Gefäßes im Bereich eines darin angeordneten Spülsteins festlegbar und mit einem an einem Zugorgan angeordneten Kupplungselement zug- und druckkraftübertragungsfähig an den Spülstein ankuppelbar ist.The invention is directed to a purging device which can be fixed on the outside of the vessel bottom of a metallurgical vessel in the region of a purging plug arranged therein and can be coupled to the purging device with a coupling element arranged on a pulling element.

In der Eisenmetallurgie finden Stahlgießpfannen als metallurgisches Gefäß Verwendung, die bodenseitig einen Lochstein mit einem darin eingesetzten Spülstein aufweisen. Diese Spülsteine unterliegen in dem jeweiligen metallurgischen Gefäß einem kontinuierlichen Verschleiß und müssen nach ca. 20-30 Schmelzen, die in dem metallurgischen Gefäß abgefüllt und behandelt worden sind, ausgetauscht werden.In iron metallurgy, foundry ladles are used as a metallurgical vessel having, on the bottom side, a perforated brick with a purge plug inserted therein. These rinsing stones are subject to continuous wear in the respective metallurgical vessel and must be replaced after about 20-30 melts which have been filled and treated in the metallurgical vessel.

Eine bekannte Methode zum Austausch eines Spülsteines einer Stahlgießpfanne umfasst den Schritt, den jeweiligen Spülstein von der Heißseite der Stahlgießpfanne, d.h. der Heißseite des metallurgischen Gefäßes, mit einem langen Dorn aus dem Gefäßboden auszustoßen. Diese Vorgehensweise ist sehr grob und ungenau und führt häufig dazu, dass der Lochstein, in dem der jeweilige Spülstein im Pfannenboden eingesetzt ist, beschädigt wird. Dies führt dazu, dass es häufig notwendig ist, die konische Spüleraufnahme des Lochsteins nachzuarbeiten, bevor dann der neue Austauschspülstein in den Lochstein eingesetzt werden kann. Das Einsetzen des Austauschspülsteins erfolgt manuell von der Außenseite des Gefäßbodens her. Bedingt durch das hohe Gewicht der Spülsteine werden diese in die Lochsteine hineingewuchtet, was kein genaues Einführen und Positionieren des Austauschspülsteins in dem jeweiligen Lochstein mit sich bringt.One known method for exchanging a sink of a ladle comprises the step of purging the respective sink from the hot side of the ladle, i. the hot side of the metallurgical vessel to eject with a long spike from the bottom of the vessel. This procedure is very crude and inaccurate and often leads to the perforated stone, in which the respective sink in the pan bottom is used, is damaged. This leads to the fact that it is often necessary to rework the conical flushing receptacle of the perforated brick before the new replacement flushing cistern can then be inserted into the perforated brick. The insertion of the replacement sink is done manually from the outside of the vessel bottom. Due to the high weight of the purging stones, they are moved into the pebbles, which does not entail a precise introduction and positioning of the replacement purging plug in the respective pitting block.

Es sind daher auch schon Spülstein-Handhabungsvorrichtungen entwickelt worden, die außenseitig am Boden eines metallurgischen Gefäßes im Bereich eines darin angeordneten Spülsteins angeordnet werden und mithilfe eines Zugorgans und eines daran angeordneten Kupplungselementes zug- und druckkraftübertragungsfähig an den Spülstein angekuppelt werden. Eine solche gattungsgemäße Spülstein-Handhabungsvorrichtung ist aus der EP 0 364 723 A1 bekannt. Bei dieser bekannten Spülstein-Handhabungsvorrichtung besteht das Zugorgan bei einem Ausführungsbeispiel aus einer Traverse, die mithilfe von in Schlitze eingetriebenen Keilen translatorisch bewegbar ist und mit dieser translatorischen Bewegung den Spülstein aus dem Lochstein herauszieht. Bei einer anderen aus der EP 0 364 723 A1 bekannten Ausführungsform umfasst die Spülstein-Handhabungsvorrichtung einen Schwenkhebel, mittels dessen zumindest zeitweise eine translatorische Bewegung auf den Spülstein ausgeübt werden kann.It is therefore already Spülstein-handling devices have been developed, the outside of the bottom of a metallurgical vessel in the region of arranged therein purging plug and be coupled by means of a tension member and a coupling element arranged thereon tensile and compressive force transferable to the sink. Such a generic Spülstein-handling device is from the EP 0 364 723 A1 known. In this known Spülstein-handling device, the tension member in one embodiment consists of a traverse, which is translationally movable by means of wedges driven in slots and pulls the purge stone from the perforated stone with this translational movement. At another from the EP 0 364 723 A1 known embodiment, the purging-handling device comprises a pivot lever, by means of which at least temporarily a translational movement can be exerted on the sink.

Die DE 10 2005 018 020 A1 beschreibt eine Vorrichtung zum Ausziehen und/oder Eindrücken eines Gasspülsteins aus einem bzw. in einen Lochstein oder Lochsteinhülse, der bzw. die in eine Wandung eines metallurgischen Gefäßes eingesetzt ist.The DE 10 2005 018 020 A1 describes a device for drawing and / or pushing a gas purging plug out of or into a perforated stone or perforated stone sleeve which is inserted in a wall of a metallurgical vessel.

Die Druckschrift EP 0 137 961 A1 zeigt eine Ausziehvorrichtung für einen Gasspülstein mit einem Gestell zum Abstützen der Vorrichtung an der Außenseite des Lochsteins bzw. der Lochsteinhülse oder an der Außenwand eines metallurgischen Gefäßes.The publication EP 0 137 961 A1 shows a puller for a gas purging plug with a frame for supporting the device on the outside of the perforated stone or the perforated stone sleeve or on the outer wall of a metallurgical vessel.

Die EP 0 270 518 A2 zeigt einen Behälter zur Behandlung von hochschmelzenden Stoffen, wie Metall- und Glasschmelzen, mit mindestens einer in seiner feuerfesten Auskleidung in Richtung gegen das Behälterinnere verschiebbar angeordneten Gasspüleinrichtung.The EP 0 270 518 A2 shows a container for the treatment of refractory materials, such as metal and glass melts, with at least one in its refractory lining in the direction of the container interior slidably arranged gas purging device.

Nachteilig bei diesen Vorrichtungen ist es, dass diese schwer zu automatisieren sind, so dass für das Herausziehen der Spülsteine aus dem jeweiligen Lochstein menschliche Arbeitskraft benötigt wird.A disadvantage of these devices is that they are difficult to automate, so that human labor is needed for the extraction of the sinks from each hole stone.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Lösung zu schaffen, die es ermöglicht, den Ein- und Ausbauvorgang eines Spülsteins eines metallurgischen Gefäßes zu automatisieren.The invention is the object of the invention to provide a solution that makes it possible to automate the installation and removal process of a purging plug of a metallurgical vessel.

Bei einer Spülstein-Handhabungsvorrichtung der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das Zugorgan eine translatorisch bewegbare Hohlspindel ist, die in einer Spindelmutter gelagert ist, welche innerhalb eines Schneckenrades drehfest mit diesem rotierbar angeordnet ist, wobei das Schneckenrad mit einer Antriebsschnecke in Eingriff steht.In a Spülstein-handling device of the type described in more detail, this object is achieved in that the tension member is a translationally movable hollow spindle, which is mounted in a spindle nut which is rotatably disposed within a worm wheel with this rotatable, wherein the worm wheel with a drive screw engaged.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments and expedient developments of the invention are the subject of the dependent claims.

Durch die Kombination eines aus Schneckenrad und Antriebsschnecke bestehenden Schneckentriebes mit einem aus Hohlspindel und Spindelmutter bestehenden Spindeltriebs ist es möglich, eine Spülstein-Handhabungsvorrichtung auszubilden, bei welcher die rotatorische Bewegung des Schneckentriebs in eine translatorische Bewegung des Spindeltriebs umgesetzt wird. Dies ermöglicht es, die Antriebsschnecke von einem Elektromotor oder Hydraulikmotor antreiben zu lassen und damit automatisiert eine Auf- und/oder Abbewegung der Hohlspindel durchzuführen. Die Hohlspindel steht als Zugorgan in der Ankoppelungsposition der als Ein- und Ausbauwerkzeug ausgebildeten Spülstein-Handhabungsvorrichtungen über ein darin ausgebildetes Kupplungselement zug- und druckkraftübertragungsfähig mit dem Spülstein in Verbindung. Dies ermöglicht es, den Ausziehvorgang und den Wiedereinsetzvorgang des Spülsteins in den Lochstein automatisiert allein durch die translatorische Bewegung der Hohlspindel durchzuführen. Die weitere Automatisierungsmöglichkeit besteht dann darin, die Spülstein-Handhabungsvorrichtungen als Ganzes mit einem Handhabungswerkzeug, aber auch mithilfe eines Industrieroboters, an den Gefäßboden und den Spülstein anzukuppeln, was beispielsweise bei entsprechend ausgebildeten Arretierungsmitteln und/oder Kupplungsmitteln mittels einer einfachen 90-Grad-Drehung möglich ist, wie nachstehend noch ausgeführt ist. Ebenso ist es möglich, mithilfe dieses Handhabungswerkzeuges oder Industrieroboters, die Spülstein-Handhabungsvorrichtung von dem metallurgischen Gefäß fortzubewegen und beispielsweise einer Pfannenschieberwerkstatt zuzuführen. Insgesamt kann ein automatisierter Prozess des Auswechselns eines Spülsteines darin bestehen, dass mithilfe eines Handhabungswerkzeuges oder Industrieroboters die Spülstein-Handhabungsvorrichtung außenseitig am Gefäßboden im Bereich des Spülsteins an den Gefäßboden sowie mit der Hohlspindel an den Spülstein angekoppelt wird und dann durch entsprechende Bewegung des Schneckentriebes mit daraus folgender Bewegung des Spindeltriebes mithilfe der Hohlspindel der Spülstein aus dem Lochstein herausgezogen wird. Daraufhin kann mithilfe eines Handhabungswerkzeuges oder Industrieroboters die Spülstein-Handhabungsvorrichtung vom Gefäßboden abgekoppelt und zusammen mit dem Spülstein der Pfannenschieberwerkstatt zugeführt werden. In der Pfannenschieberwerkstatt kann dann der Spülstein ausgetauscht und ein neuer Spülstein an die Hohlspindel angekoppelt werden. Mit diesem neuen Spülstein wird die Spülstein-Handhabungsvorrichtung dann von dem Handhabungswerkzeug oder dem Industrieroboter wiederum dem Gefäßboden zugeführt und an diesem festgelegt. Daraufhin kann durch erneute Betätigung des Schneckentriebes der Spindeltrieb betätigt werden und durch entsprechende translatorische Bewegung der neue Spülstein in den Lochstein des metallurgischen Gefäßes von außen eingesetzt werden. Natürlich ist dieser vorher mit entsprechender Mörtelmasse versehen worden.By combining a worm gear consisting of worm and drive worm drive with a spindle drive consisting of hollow spindle and spindle nut, it is possible to form a purge stone handling device in which the rotational movement of the worm drive is converted into a translational movement of the spindle drive. This makes it possible to drive the drive worm of an electric motor or hydraulic motor and thus automatically perform an up and / or down movement of the hollow spindle. The hollow spindle is as tension member in the Ankoppelungsposition designed as an installation and removal tool Spülstein-handling devices via a coupling element formed therein tensile and compressive force transferable with the sink in combination. This makes it possible to carry out the extraction process and the reinsertion process of the purging plug into the perforated brick automatically only by the translational movement of the hollow spindle. The further automation option then consists in coupling the purging device as a whole with a handling tool, but also by means of an industrial robot, to the bottom of the vessel and the purging device, which is possible, for example, with correspondingly formed locking means and / or coupling means by means of a simple 90 degree rotation is, as will be explained below. It is also possible, with the aid of this handling tool or industrial robot, to move the purging device from the metallurgical vessel and, for example, to feed it to a ladle pusher. Overall, an automated process of replacing a purging plug may be that using a handling tool or industrial robot, the purging device is externally coupled to the bottom of the vessel in the region of the purging plug to the bottom of the vessel and with the hollow spindle to the sink and then by appropriate movement of the worm drive with it the following movement of the spindle drive using the hollow spindle of the purging plug is pulled out of the hole stone. Then, using a handling tool or industrial robot, the purge-handling device disconnected from the bottom of the vessel and together with the purging the Pfannenschieberwerkstatt be supplied. In the pan pusher workshop then the sink can be replaced and a new sink to the hollow spindle are coupled. With this new purging the purging stone handling device is then again supplied by the handling tool or the industrial robot the vessel bottom and fixed to this. Then can be actuated by re-actuation of the worm drive of the spindle drive and be inserted by appropriate translational movement of the new sink in the hole stone of the metallurgical vessel from the outside. Of course, this has previously been provided with appropriate mortar mass.

Um diese Automatisierungsabläufe und die gleichzeitige Ankopplung der Hohlspindel an den Spülstein und der Spülstein-Handhabungsvorrichtung an den Gefäßboden realisieren zu können, sieht die Erfindung in zweckmäßiger Ausgestaltung vor, dass das Schneckenrad und die Antriebsschnecke in einem Getriebekasten angeordnet sind, der mittels damit in Wirkverbindung stehender Arretierungsmittel an dem Gefäßboden festlegbar ist.In order to be able to realize these automation processes and the simultaneous coupling of the hollow spindle to the sink and the sink handling device on the bottom of the vessel, the invention provides in an expedient embodiment that the worm wheel and the drive worm are arranged in a gear box which is in operative connection therewith Arretierungsmittel is fixed to the bottom of the vessel.

Von besonderem Vorteil ist es hierbei gemäß Weiterbildung der Erfindung, dass die Arretierungsmittel Bestandteil eines am Gefäßboden ausgebildeten Bajonettverschlusses sind. Mithilfe eines Bajonettverschlusses ist es möglich, eine Befestigung der an der Spülstein-Handhabungsvorrichtung ausgebildeten Arretierungsmittel mit am Gefäßboden ausgebildeten Gegenmitteln allein durch eine Drehbewegung der Spülstein-Handhabungsvorrichtung um ca. 90 Grad nach Einführung der an der Spülstein-Handhabungsvorrichtung ausgebildeten Arretierungsmittel in die am Gefäßboden ausgebildeten Gegenmittel zu erreichen.It is particularly advantageous according to the invention that the locking means are part of a bayonet closure formed on the bottom of the vessel. With the aid of a bayonet closure, it is possible to attach the locking means formed on the sink handling device to counter-means formed on the bottom of the vessel by rotation of the sink handling device by approximately 90 degrees after insertion of the locking means formed on the sink handling device into the bottom of the vessel To achieve antidote.

Eine besonders zweckmäßige Ankopplung von Spülstein-Handhabungsvorrichtung und Spülstein lässt sich dadurch erreichen, dass in der Ankoppelungsposition der Spülstein-Handhabungsvorrichtung an den Spülstein dieser mit einem daran hervorstehenden Gasspülrohr in die Hohlspindel hineinragt. Dies ermöglicht es, den Spülstein in der Hohlspindel geführt zu halten und Befestigungs- oder Kupplungselemente vorzusehen, mit welchen der Spülstein zug- und druckkraftübertragungsfähig im Ankoppelungszustand bzw. in der Ankoppelungsposition erfassbar oder erfasst ist.A particularly expedient coupling of purging device and purging plug can be achieved by protruding into the hollow spindle in the coupling position of the purging device with the purging device with a gas purging pipe projecting therefrom. This makes it possible to keep the purge in the hollow spindle and provide fastening or coupling elements with which the Sink train and compressive force capable of transmission in Ankoppelungszustand or in Ankoppelungsposition is detected or detected.

Bei einer häufig verwendeten Form eines Spülsteins weist dieser an seinem Gasspülrohr einen Flansch oder Ringflansch auf. Die Erfindung sieht daher in zweckmäßiger Weiterbildung vor, dass der Kopf der Hohlspindel ein in der Ankoppelungsposition der Spülstein-Handhabungsvorrichtung an den Spülstein zug- und druckkraftübertragungsfähig an einen Flansch des Gasspülrohres angelegtes Kupplungselement aufweist. Mithilfe eines solchen Kupplungselementes lässt sich auf einfache Art und Weise eine zug- und druckkraftübertragungsfähige Verbindung mit dem Flansch des Gasspülrohres des Spülsteines herstellen.In a frequently used form of a purging plug, this has a flange or annular flange on its gas purging pipe. The invention therefore provides in an expedient development that the head of the hollow spindle in the Ankoppelungsposition the Spülstein-handling device to the purging and tensile force and druckkraftübertragungsfähig has applied to a flange of the gas purging pipe coupling element. With the help of such a coupling element can be in a simple manner a tensile and compressive force transferable connection with the flange of the gas purging pipe of the sink produce.

Um die Verbindung besonders gut zug- und druckkraftübertragungsfähig auszubilden, sieht die Erfindung weiterhin vor, dass das Kupplungselement zumindest bereichsweise beidseitig unter Umgreifung des Flanschrandes an dem Flansch anliegt. Da das Kupplungsband oberseitig und unterseitig auf dem Flansch anliegt, ist bei der vorgesehenen translatorischen Bewegung in beide Richtungen eine Kraftübertragung entweder als Zugkraft oder als Druckkraft möglich. Durch die Umgreifung des Flanschrandes wird erreicht, dass nicht nur ein Teil des Gasspülrohres in der Hohlspindel geführt ist, sondern auch der Flansch in dem Kupplungselement zentriert gehalten ist.In order to form the connection particularly well tensile and compressive force transferable, the invention further provides that the coupling element rests at least partially on both sides while encompassing the flange edge on the flange. Since the coupling band rests on the top and bottom of the flange, a force transmission either as a tensile force or as a compressive force is possible in the proposed translational movement in both directions. By encompassing the flange edge is achieved that not only a part of the gas purging pipe is guided in the hollow spindle, but also the flange is held centered in the coupling element.

Um die Ankoppelung des Kupplungselementes an den Flansch des Gasspülrohres ebenfalls mit einer Drehbewegung in der Größenordnung von bis zu 90 Grad realisieren zu können, zeichnet sich die Erfindung in Weiterbildung dadurch aus, dass das Kupplungselement mit zugeordneten Ausnehmungen des Flansches zusammenwirkende Vorsprünge aufweist, die von der dem Spülstein abgewandten Seite des Flansches durch die Ausnehmungen hindurch führbar und nach anschließender Relativerdrehung von Gasspülrohr und Spülstein-Handhabungsvorrichtung zueinander auf der dem Spülstein zugewandten Seite des Flansches positioniert sind. Diese Ausführungsform ermöglicht es, das Kupplungselement von der dem Spülstein abgewandten Seite durch die Ausnehmungen des Flansches hindurch auf den Flansch aufzuschieben und dann durch anschließende Relativverdrehung, beispielsweise eine Drehung um 90 Grad, diese von den Ausnehmungen fortzubewegen und auf der dem Spülstein zugewandten Seite des Flansches zu positionieren. Diese Drehbewegung kann gleichzeitig mit der Verschlussbewegung der Arretierungsmittel der Spülstein-Handhabungsvorrichtung mit den Gegenmitteln des Gefäßbodens erfolgen, weshalb die Erfindung schließlich auch dadurch gekennzeichnet ist, dass die mit dem Gefäßboden in Arretierungsverbindung zu bringenden Arretierungsmittel und das mit dem Flansch in Wirkverbindung zu bringende Kupplungselement derart angeordnet oder ausgerichtet sind, dass mit einer Relativverdrehung von Spülstein und Spülstein-Handhabungsvorrichtung zueinander beide gleichzeitig in ihre jeweilige Ankopplungsposition bringbar sind.In order to realize the coupling of the coupling element to the flange of the gas purging pipe also with a rotational movement in the order of up to 90 degrees, the invention is characterized in a further development that the coupling element having associated recesses of the flange cooperating projections, which of the the side facing away from the purging of the flange through the recesses can be guided and positioned after subsequent relative rotation of gas purging pipe and purging device to each other on the side facing the purging of the flange. This embodiment makes it possible Coupling of the side facing away from the purging plug through the recesses of the flange on the flange postponed and then by subsequent relative rotation, for example, a rotation of 90 degrees to move them from the recesses and to position on the side facing the purging of the flange. This rotational movement can take place simultaneously with the closing movement of the locking means of the purging device with the antidote means of the vessel bottom, which is why the invention finally also characterized in that the arresting means to be brought into locking connection with the vessel bottom and the coupling element to be brought into operative connection with the flange are arranged or aligned, that with a relative rotation of the sink and sink handling device to each other both at the same time in their respective coupling position can be brought.

Die insgesamt mit 1 bezeichnete Spülstein-Handhabungsvorrichtung in Form eines Ein- und Ausbauwerkzeugs 2 umfasst einen Getriebekasten 3, in welchem in senkrechter Anordnung zueinander eine Antriebsschnecke 4 und eine Hohlspindel 5 angeordnet und/oder gelagert sind. Die Hohlspindel 5 ist in einer Spindelmutter 6 geführt angeordnet und bildet zusammen mit dieser einen Spindeltrieb aus. Die Spindelmutter 6 ihrerseits ist drehfest und verdrehfest innerhalb eines Schneckenrades 7 angeordnet, so dass die Spindelmutter 6 zwar nicht relativ zum Schneckenrad 7 bewegbar, aber mit diesem zusammen rotierbar in dem Getriebekasten 3 angeordnet ist. Das Schneckenrad 7 steht über einen außenseitig umlaufenden Zahnkranz 8 mit der Antriebsschnecke 4 in Wirkverbindung und bildet zusammen mit dieser einen Schneckentrieb aus, welcher ebenfalls innerhalb des Getriebekastens 3 angeordnet ist. Mithilfe dieser Kombination von Schneckentrieb und Spindeltrieb ist es möglich, die Rotationsbewegung der Antriebsschnecke 4 und daraus resultierend die Rotationsbewegung von Schneckenrad 7 und Spindelmutter 6 in eine dadurch bewirkte translatorische Bewegung der Hohlspindel 5 umzuwandeln. In der in den Fig. 4-6 dargestellten Ankoppelungsposition der Spülstein-Handhabungsvorrichtung 1 an den Gefäßboden 9 eines metallurgischen Gefäßes 10, insbesondere einer Stahlgießpfanne, ist es somit möglich, durch Änderung der Drehbewegung der Antriebsschnecke 4 eine Auf- oder Abbewegung der Hohlspindel 5 in Richtung des Doppelpfeiles 11 auszuführen.The generally designated 1 Spülstein-handling device in the form of an installation and removal tool 2 comprises a gearbox 3, in which in a vertical arrangement to each other a drive screw 4 and a hollow spindle 5 are arranged and / or stored. The hollow spindle 5 is arranged guided in a spindle nut 6 and forms together with this a spindle drive. The spindle nut 6 in turn is non-rotatably and non-rotatably disposed within a worm wheel 7, so that the spindle nut 6 is not movable relative to the worm wheel 7, but rotatably arranged together in the gear box 3. The worm wheel 7 is connected via an outside circumferential ring gear 8 with the drive screw 4 in operative connection and forms together with this a worm drive, which is also disposed within the gear box 3. With the aid of this combination of worm drive and spindle drive, it is possible to convert the rotational movement of the drive worm 4 and, as a result, the rotational movement of worm wheel 7 and spindle nut 6 into a translational movement of the hollow spindle 5 effected thereby. In the in the Fig. 4-6 illustrated Ankoppelungsposition the Spülstein-handling device 1 to the vessel bottom 9 of a metallurgical vessel 10, in particular a Stahlgießpfanne, it is thus possible to perform an up or down movement of the hollow screw 5 in the direction of the double arrow 11 by changing the rotational movement of the drive screw 4.

Am Kopf der Hohlspindel 5, auf der in der Ankoppelungsposition dem Spülstein 12 zugewandten Seite, ist ein Kupplungselement 13 ausgebildet. Das Kupplungselement 13 erfasst zug- und druckkraftübertragungsfähig einen am Gasspülrohr 14 ausgebildeten Flansch 15. Das Gasspülrohr 14 ist Bestandteil des in seiner Gebrauchsposition in einen im Gefäßboden 9 eingelassenen Lochstein 16 eingesetzten Spülsteins 12. Die Hohlspindel 5 bildet ein Zugorgan aus, das mittels seines Kupplungselementes 13 Druck- oder Zugkräfte aufgrund der Ankoppelung an den Flansch 15 auf das Gasspülrohr 14 und damit den Spülstein 12 ausüben kann. Die Fig. 1 zeigt die Ankoppelungsposition des Kupplungselements 13 an den Flansch 15 und damit die Ankoppelungsposition der Spülstein-Handhabungsvorrichtung 1 an den Spülstein 12. In dieser Ankoppelungsposition liegt das Kupplungselement 13 zumindest bereichsweise beidseitig unter Umgreifung des Flanschrandes an dem Flansch 15 an. Ebenso ragt in dieser Ankoppelungsposition der Spülstein 12 mit seinem Gasspülrohr 14 in die Hohlspindel 5 hinein, wobei dies mittels eines in der Darstellung der Fig. 1 unterhalb des Flansches 15 ausgebildeten Abschnittes 14a des Gasspülrohres 14 realisiert ist.At the head of the hollow spindle 5, on the side facing the sink 12 in the coupling position, a coupling element 13 is formed. The gas flow tube 14 is part of the inserted into its use position in a recessed in the bottom of the vessel 9 perforated brick 16 purging plug 12. The hollow spindle 5 forms a tension member, by means of its coupling element thirteenth Pressure or tensile forces due to the coupling to the flange 15 on the gas purging pipe 14 and thus the purge 12 can exercise. The Fig. 1 shows the Ankoppelungsposition of the coupling element 13 to the flange 15 and thus the Ankoppelungsposition the Sink-handling device 1 to the sink 12. In this Ankoppelungsposition the coupling element 13 is at least partially on both sides while encompassing the flange to the flange 15 at. Likewise, in this Ankoppelungsposition the purging block 12 projects with its gas purging pipe 14 into the hollow spindle 5, wherein this by means of a in the representation of Fig. 1 realized below the flange 15 formed portion 14 a of the gas purging pipe 14.

Um das Kupplungselement 13 an dem Flansch 15 festlegen zu können, sind an dem Flansch diametral gegenüberliegend zwei Ausnehmungen 17 ausgebildet. An die Geometrie der Ausnehmungen 17 angepasst, weist das Kupplungselement 13 zwei korrespondierend ausgebildete und korrespondierend angeordnete Vorsprünge 18 auf, die radial nach innen vorspringen. Zur Ankoppelung des Kupplungselementes 13 in die in der Figur 1 dargestellt Ankoppelungsposition an das Gasspülrohr 14 des Spülsteins 12 werden die Vorsprünge 18 von der Seite des Abschnittes 14a des Gasspülrohres 14 durch die Ausnehmungen 17 hindurchgeführt und wird anschließend eine Drehung der Spülstein-Handhabungsvorrichtung 1 relativ zum Flansch 15, und damit zum Spülstein 12, um 90 Grad durchgeführt, so dass die Vorsprünge 18 sich anschließend in den in Fig. 3 dargestellten Positionen befinden. In dieser Position liegen die Vorsprünge 18 nun auf der dem Abschnitt 14a des Gasspülrohres abgewandten Seite auf dem Flansch 15 auf, wobei die gegenüber liegende Seite des Flansches 15 gleichzeitig an der oberen Mündungsöffnung der Hohlspindel 5 aufliegt. Hierdurch ist eine zug- und druckkraftübertragungsfähige Verbindung zwischen dem Gasspülrohr 14, und damit dem Spülstein 12, und der Hohlspindel 5, und damit der Spülstein-Handhabungsvorrichtung 1, ausgebildet.In order to fix the coupling element 13 on the flange 15, two recesses 17 are formed on the flange diametrically opposite one another. Adapted to the geometry of the recesses 17, the coupling element 13 has two correspondingly formed and correspondingly arranged projections 18 which protrude radially inwards. To couple the coupling element 13 in the in the FIG. 1 shown coupling position to the gas purging tube 14 of the pumice 12, the projections 18 are passed from the side of the portion 14a of the gas purging tube 14 through the recesses 17 and then rotation of the purging device 1 relative to the flange 15, and thus the purging 12, 90th Degree performed so that the projections 18 are then in the in Fig. 3 positions are shown. In this position, the projections 18 are now on the side facing away from the portion 14a of the gas purging pipe on the flange 15, wherein the opposite side of the flange 15 simultaneously rests on the upper mouth opening of the hollow spindle 5. As a result, a tensile and compressive force transferable connection between the gas purging pipe 14, and thus the purging 12, and the hollow spindle 5, and thus the purging-handling device 1, is formed.

Zur Festlegung der Spülstein-Handhabungsvorrichtung 1 am Gefäßboden 9 des metallurgischen Gefäßes 10 im Bereich des dort eingelassenen Spülsteines 12 ist die Spülstein-Handhabungsvorrichtung 1 mit symmetrisch angeordneten Arretierungsmitteln 19 ausgestattet, die mit korrespondierend dazu angeordneten und ausgebildeten, gefäßaußenseitig am Gefäßboden 9 angeordneten Gegenmitteln 20 jeweils einen Bajonettverschluss 21 ausbilden. Die Arretierungsmittel 19 sind jeweils endseitig an einer Strebe 22 angeordnet, deren anderes Ende an dem Getriebekasten 3 befestigt ist.In order to fix the purging device 1 at the bottom 9 of the metallurgical vessel 10 in the region of the purging plug 12, the purging device 1 is equipped with symmetrically arranged locking means 19, which are arranged and configured with corresponding countermeasures arranged on the vessel bottom 9 20 each form a bayonet 21. The locking means 19 are each end to a strut 22, the other end is fixed to the gearbox 3.

Aufgrund dieser Anordnung und Ausbildung der Arretierungsmittel 19 mit zugeordneten Gegenmitteln 20 sowie des Kupplungselementes 13 mit den darin ausgebildeten Vorsprüngen 18 und des zugeordneten Flansches 15 mit den darin ausgebildeten Ausnehmungen 17 ist es möglich, zunächst gemeinsam einerseits die Arretierungsmittel 19 und die Gegenmittel 20 und andererseits das Kupplungselement 13 und den Flansch 15 in eine erste Kooperationsposition zu bewegen und dann durch eine einzige Drehung um 90 Grad gleichzeitig sowohl den Bajonettverschluss 21 in die Ankoppelungsposition und das Kupplungselement 13 und den Flansch 15 in ihre Ankoppelungsposition und damit insgesamt die Spülstein-Handhabungsvorrichtung 1 in ihre Ankoppelungsposition zu bringen.Due to this arrangement and design of the locking means 19 with associated counter means 20 and the coupling element 13 with the projections 18 formed therein and the associated flange 15 with the recesses 17 formed therein, it is possible, first together on the one hand, the locking means 19 and the antidote 20 and the other Clutch element 13 and the flange 15 to move to a first cooperation position and then by a single rotation by 90 degrees simultaneously both the bayonet 21 in the Ankoppelungsposition and the coupling element 13 and the flange 15 in its Ankoppelungsposition and thus the total Spülstein-handling device 1 in her Bring coupling position.

Als Antrieb für die Antriebsschnecke 4 ist ein Elektro- oder Hydraulikmotor oder -antrieb 23 vorgesehen.As drive for the drive screw 4, an electric or hydraulic motor or drive 23 is provided.

Zum Auswechseln eines Spülsteins 12 wird die Spülstein-Handhabungsvorrichtung 1 zunächst in die in Fig. 4 dargestellte Ankoppelungsposition gebracht, in welcher die Arretierungsmittel 19 und die Gegenmittel 20 sowie das Kupplungselement 13 und der Flansch 15 in wirksamer Kopplungsverbindung miteinander stehen. Es wird nun der Schneckentrieb derart bewegt, dass daraus eine Abwärtsbewegung der als Zugorgan ausgebildeten Hohlspindel 5 und damit eine Zugkrafteinwirkung auf den Spülstein 12 resultieren. Dieser löst sich aus seiner Position im Lochstein 16 und wird aus diesem, wie es in der Fig. 5 dargestellt ist, in Richtung des Doppelpfeiles 11 herausgezogen, bis das Kupplungselement 13 in seine Anschlagsposition auf der Oberseite des Getriebekastens 3 aufsetzt, wie dies aus Fig. 6 ersichtlich ist. Dieser Vorgang kann vollkommen automatisiert ablaufen, ohne dass menschliche Arbeitskräfte manuell eingreifen müssen. Mithilfe eines entsprechenden Handhabungswerkzeuges oder eines Industrieroboters ist es dann weiterhin möglich, ausgehend von der in Fig. 6 dargestellten Position, die Spülstein-Handhabungsvorrichtung von dem Handhabungswerkszeug oder Industrieroboter erfassen und durch entsprechende Drehung den Bajonettverschluss 21 lösen zu lassen. Das Handhabungswerkzeug oder der Industrieroboter kann nun die mit dem Spülstein 12 versehene Spülstein-Handhabungsvorrichtung 1 in eine Pfannenschieberwerkstatt befördern und dort absetzen. Dort wird der verschlissene Spülstein 12 aus der Spülstein-Handhabungsvorrichtung herausgelöst. Auch dies kann mit entsprechenden Handhabungswerkzeugen gewünschtenfalls automatisiert erfolgen, da hierzu lediglich eine Erfassung des Spülsteines 12 und eine Relativbewegung zur Spülstein-Handhabungsvorrichtung 1 derart notwendig ist, dass die Vorsprünge 18 wiederum in Deckung mit den Ausnehmungen 17 gelangen, woraufhin dann durch eine einfache Ziehbewegung der Spülstein 12 aus der Spülstein-Handhabungsvorrichtung 1 lösbar ist. In umgekehrter Bewegungsabfolge kann ein neuer Ziehstein 12 in die Spülstein-Handhabungsvorrichtung 1 eingesetzt werden, woraufhin diese dann mit dem neuen Spülstein 12 in die in Fig. 6 dargestellte Ankoppelungsposition am Gefäßboden 9 des metallurgischen Gefäßes 10 gebracht wird. In rückwärtiger Abfolge der Figuren 6, 5, 4 kann dann durch entsprechende translatorische Bewegung der Hohlspindel 5 der neue Spülstein 12 in den Lochstein 16 im Gefäßboden 2 eingesetzt werden. Hierzu ist in der Pfannenwerkstatt die Außenseite des neuen Spülsteines 12 vorher wie üblich mit einer Mörtelmasse versehen worden. Um sicherzustellen, dass die Hohlspindel den neuen Spülstein 12 mit dem richtigen Einpressdruck in den Lochstein 16 einsetzt, kann der Antrieb 23 mit einer Drehmomentüberwachung ausgestattet sein.To replace a purging plug 12, the purging device 1 is first in the in Fig. 4 shown coupling position in which the locking means 19 and the counter-agent 20 and the coupling element 13 and the flange 15 are in effective coupling connection with each other. The worm drive is now moved in such a way that it results in a downward movement of the hollow spindle 5 designed as a pulling element and thus a tensile force acting on the purge block 12. This releases itself from its position in the perforated stone 16 and becomes from this, as it in the Fig. 5 is shown pulled out in the direction of the double arrow 11 until the coupling element 13 is placed in its stop position on the top of the gear box 3, as is apparent from Fig. 6 is apparent. This process can be completely automated without the need for human intervention. Using an appropriate handling tool or an industrial robot, it is then still possible, starting from the in Fig. 6 illustrated position, the Spülstein-handling device of the handling tool or industrial robot capture and solve by appropriate rotation the bayonet 21. The handling tool or the industrial robot can now carry the provided with the sink 12 Spülstein-handling device 1 in a Pfannenschieberwerkstatt and settle there. There, the worn purging block 12 is dissolved out of the purging device. This, if desired, can also be automated with corresponding handling tools, since only a detection of the sink 12 and a relative movement to the sink handling device 1 is necessary in such a way that the projections 18 in turn come into coincidence with the recesses 17, whereupon by a simple pulling movement of the Purge 12 from the purge-handling device 1 is releasable. In reverse sequence of movement, a new die 12 can be used in the sink handling device 1, whereupon this then with the new sink 12 in the in Fig. 6 shown Ankoppelungsposition is brought to the bottom of the vessel 9 of the metallurgical vessel 10. In the backward sequence of FIGS. 6 . 5, 4 can then be inserted through appropriate translational movement of the hollow spindle 5 of the new sink 12 in the hole stone 16 in the vessel bottom 2. For this purpose, in the pan workshop, the outside of the new sink 12 has previously been provided as usual with a mortar composition. To ensure that the hollow spindle uses the new purging plug 12 with the correct injection pressure in the perforated brick 16, the drive 23 may be equipped with a torque monitoring.
