Description

Die Erfindung betrifft eine Einrichtung zur Medienversorgung einer Blaslanze für ein metallurgisches Gefäß, insbesondere einen Stahlwerkskonverter, mit mindestens einer auf einem in und außer Blasposition verfahrbaren Trägerwagen angeordneten Blaslanze.The invention relates to a device for supplying media to a blowing lance for a metallurgical vessel, in particular a steelwork converter, with at least one blowing lance arranged on a carrier carriage which can be moved into and out of the blowing position.

Zur Medienversorgung von Blaslanzen mit Sauerstoff, Kühlwasser und gegebenenfalls Brennstoffen und Zuschlagstoffen, ist es bekannt, den verfahrbaren Trägerwagen mittels Schläuchen an die Zubringerleitungen für diese Medien anzuschließen. Im Trägerwagen selbst ist ein von den Schläuchen ausgehendes, aus .den Schläuchen oder Gliederrohren gebildetes Leitungssystem zur gegenüber dem Trägerwagen heb- und senkbaren Blaslanze angeordnet.To supply media to blowing lances with oxygen, cooling water and, if appropriate, fuels and additives, it is known to connect the movable carrier wagon to the feed lines for these media by means of hoses. Arranged in the carrier car itself is a line system, which starts from the hoses and is formed from the hoses or limb tubes, to the blowing lance, which can be raised and lowered relative to the carrier car.

Die Fahrstrecke des Trägerwagens ist durch die Länge der Schläuche begrenzt. Befindet sich der Trägerwagen in der Nähe der Zubringerleitungen, so hängen die Schläuche weit herab, . wodurch die Länge der Schläuche und damit die Fahrstrecke des Trägerwagens beschränkt ist. Bei jedem Verfahren des Trägerwagens kommt es zu einer Biegebeanspruchung der Schläuche, wodurch die Lebensdauer und Betriebssicherheit der Schläuche Einbußen erleidet. Ein weiterer Nachteil der bekannten Einrichtung ist darin zu sehen, daß durch die Ortsgebundenheit des Trägerwagens für jeden Konverter ein eigener Trägerwagen vorgesehen werden mußte.The route of the carrier car is limited by the length of the hoses. If the carrier wagon is close to the feeder lines, the hoses hang far down. whereby the length of the hoses and thus the distance traveled by the carrier wagon is limited. Every time the carrier is moved, the hoses are subjected to bending stress, which means that the hoses' lifespan and operational reliability suffer. Another disadvantage of the known device can be seen in the fact that, due to the location-specific nature of the carrier car, a separate carrier car had to be provided for each converter.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, eine Einrichtung der eingangs bezeichneten Art zu schaffen, bei der der Trägerwagen entlang seiner Fahrstrecke beliebig weit und ohne durch Schlauchleitungen behindert zu sein, verfahrbar ist, so daß er für zumindest zwei Konverter eingesetzt werden kann. Eine weitere Aufgabe der Erfindung besteht darin, die Medienzuführungsleitung zum Trägerwagen betriebssicherer zu gestalten.The invention aims to avoid these disadvantages and difficulties and has the object to provide a device of the type mentioned, in which the carrier car along its route as far as possible and without being hindered by hose lines, so that it can be used for at least two Converter can be used. Another object of the invention is to make the media feed line to the carrier wagon more reliable.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß ein mit einer Medienversorgungsleitung verbundenes Anschlußstück ortsfest an der Fahrbahn des in Blasposition gefahrenen Trägerwagens angeordnet ist, mit dem ein korrespondierendes am Trägerwagen montiertes Anschlußgegenstück leitungsmäßig verbindbar ist.According to the invention, these objects are achieved in that a connection piece connected to a media supply line is arranged in a stationary manner on the carriageway of the carrier carriage driven in the blowing position, with which a corresponding connection counterpart mounted on the carrier carriage is connectable.

Um eine sicher dichtende Verbindung der ortsfesten Medienzuführungsleitung zu der im Trägerwagen angeordneten zu erreichen, ist vorteilhaft jedes Anschlußgegenstück am Trägerwagen mit Bewegungsspiel befestigt und mittels einer Klemmeinrichtung an das korrespondierende ortsfeste Anschlußstück anpreßbar.In order to achieve a securely sealing connection of the stationary media supply line to that arranged in the carrier carriage, each connection counterpart is advantageously fastened to the carrier carriage with play and can be pressed onto the corresponding stationary connection piece by means of a clamping device.

Nach einer bevorzugten Ausführungsform sind bei einer Mehrzahl von Medienversorgungsleitungen die ortsfesten Anschlußstücke gemeinsam an einer Anschlußplatte und die korrespondierenden Anschlußgegenstücke gemeinsam an einer Anschlußgegenplatte montiert.According to a preferred embodiment, in the case of a plurality of media supply lines, the fixed connection pieces are mounted together on a connection plate and the corresponding connection counter pieces are mounted together on a connection counter plate.

Dabei ist zweckmäßig die Anschlußgegenplatte parallel zur Fahrrichtung des Trägerwagens anzuordnen und mittels Gelenkhebel am Trägerwagen um einen in Fahrrichtung des Trägerwagens angeordneten Bolzen verschwenkbar anzulenken, wodurch die Anschlußgegenplatte gegenüber der ortsfesten Anschlußplatte genau in Anschlußposition bringbar ist.It is expedient to arrange the connection counterplate parallel to the direction of travel of the carrier carriage and to pivot it by means of articulated levers on the carrier carriage by means of a pivot arranged in the direction of travel of the carrier carriage, whereby the connection counterplate can be brought exactly into the connection position relative to the stationary connection plate.

Dabei ist zweckmäßig die Anschlußgegenplatte am Trägerwagen zur Fahrrichtung des Trägerwagens parallel verschiebbar angeordnet, sodaß es möglich ist, die Anschlußgegenplatte gegen die ortsfeste Anschlußplatte anzupressen.The connection counterplate on the carrier carriage is expediently arranged to be displaceable parallel to the direction of travel of the carrier carriage, so that it is possible to press the connection counterplate against the stationary connection plate.

Zu diesem Zweck dient vorteilhaft ein an der ortsfesten Anschlußplatte montiertes Kupplungsstück, welches die Anschlußgegenplatte des in Blasposition gefahrenen Trägerwagens übergreift und einen an der Anschlußgegenplatte angreifenden Druckmittelzylinder aufweist.For this purpose, a coupling piece which is mounted on the stationary connecting plate and which engages over the connecting counterplate of the carrier carriage moved into the blowing position and has a pressure medium cylinder acting on the connecting counterplate is advantageously used.

Es ist vorteilhaft, wenn die Anschlußgegenplatte mit mindestens einem Stützrad versehen ist, welches auf einer parallel zur Fahrstrecke des Trägerwagens angeordneten Schiene abgestützt ist. Dadurch wird die Anschlußgegenplatte unabhängig von den Eigenbewegungen des Trägerwagens stets in richtiger Position zur Anschlußplatte gehalten.It is advantageous if the connection counterplate is provided with at least one support wheel which is supported on a rail arranged parallel to the travel path of the carrier car. As a result, the connection counterplate is always held in the correct position relative to the connection plate, regardless of the carrier carriage's own movements.

Nach einer zweckmäßigen Ausgestaltung der Erfindung führen in einer Halle,in der mindestens zwei Konverter vorgesehen sind, zu jedem der Konverter Medienversorgungsleitungen, an deren ortsfeste Anschlußstücke ein zwischen diesen Anschlußstücken verfahrbarer Trägerwagen wahlweise anschließbar ist.According to an expedient embodiment of the invention, in a hall in which at least two converters are provided, media supply lines lead to each of the converters, and a carrier carriage which can be moved between these connection pieces can optionally be connected to the fixed connection pieces.

Die Erfindung ist anhand eines Ausführungsbeispieles in der Zeichnung näher erläutert, wobei Fig. 1 in schematischer Darstellung zwei nebeneinander angeordnete Konverterblasstände in Seitenansicht und Fig. 2 im Grundriß zeigt.The invention is explained in more detail using an exemplary embodiment in the drawing, with FIG. 1 showing a schematic illustration of two converter blowing stands arranged side by side and FIG. 2 in plan view.

Fig. 3 zeigt, ebenfalls in schematischer Darstellung, den Trägerwagen in Seitenansicht in Richtung des Pfeiles III der Fig. 2. Fig. 4 gibt einen Grundriß der Fig. 3, teilweise geschnitten nach der Linie IV-IV, in vergrößertem Maßstab wieder.Fig. 3 shows, also in a schematic representation, the carrier car in a side view in the direction of arrow III of Fig. 2. Fig. 4 shows a plan of Fig. 3, partly cut along the line IV-IV, on an enlarged scale.

In Fig. 1 sind zwei nebeneinanderliegende Blasstände mit Konvertern 3, 4 mit 1 und 2 bezeichnet. Oberhalb der Konverter ist ein Trägerwagen 5, der mit zwei Blaslanzen 6, 7, u. zw. mit einer Blaslanze 6 als Betriebslanze und mit einer Blaslanze 7 als Reservelanze für den Fall einer Beschädigung der ersten, ausgestattet ist, entlang von an einem Träger 8 montierten Schienen 9, 10 und 11 verfahrbar. Parallel zu den Schienen sind für jeden Blasstand Medienzuführungsleitungen 12, 13, und 14 bzw. 12', 13' und 14' für die Zufuhr von Sauer- stoff und für dreZu- und Ableitung eines Kühlmittels ortsfest verlegt. Es können noch weitere Medienleitungen vorgesehen sein, z.B. für ein Heizgas oder für Zuschlagstoffe. An jedem Blasstand sind für jede der Leitungen Anschlußstücke 15, die gemeinsam in einer Anschlußplatte 16 montiert sind, ortsfest angeordnet. Der Trägerwagen 5 weist für jede der an ihm heb-und senkbar montierten Blaslanzen 6, 7 zu den ortsfesten Anschlußstücken 15 korrespondierende Anschlußgegenstücke 17, 17', die jeweils in einer Anschlußgegenplatte 18, 18' gemeinsam montiert sind, auf, von denen Rohrleitungen 19, 19' und Schlauchleitungen 19", 19"' für die genannten Medien zu den Blaslanzen 6, 7 führen.In Fig. 1 two adjacent blowing stands with converters 3, 4 are designated 1 and 2. Above the converter is a carrier car 5, which with two blowing lances 6, 7, u. is equipped with a blowing lance 6 as the operating lance and with a blowing lance 7 as the spare lance in the event of damage to the first, along rails 9, 10 and 11 mounted on a carrier 8. In parallel to the rails, media supply lines 12, 13 and 14 or 12 ', 13' and 14 'for the supply of oxygen and for the supply and discharge of a coolant are fixed in place for each blowing station. Additional media lines can be provided, e.g. for a heating gas or for aggregates. At each blowing stand for each of the lines connecting pieces 15, which are mounted together in a connecting plate 16, are arranged in a fixed position. The carrier carriage 5 has, for each of the blowing lances 6, 7 mounted on it, which can be raised and lowered, corresponding to the fixed connecting pieces 15, connecting counter pieces 17, 17 ', which are each mounted together in a connecting counter plate 18, 18', of which pipes 19, 19 'and hose lines 19 ", 19"' for the media mentioned lead to the blowing lances 6, 7.

Wie aus Fig. 2 ersichtlich ist, ist jeweils die Anschlußgegenplatte derjenigen Blaslanze an die ortsfeste Anschlußplatte anschließbar, die sich über dem Konverter befindet.As can be seen from FIG. 2, the connection counterplate of the blowing lance can be connected to the fixed connection plate, which is located above the converter.

Die öffnungen der Medienversorgungsleitungen, die nicht an den Trägerwagen angeschlossen sind, bzw. die öffnungen der nicht angeschlossenen Leitungen im Trägerwagen sind mittels nicht dargestellter Staubschutzkappen entweder manuell oder mittels einer Fernsteuerung verschließbar. Die am Trägerwagen vorgesehenen Anschlußgegenplatten 18, 18' sind mit Gelenkhebel 20 am Trägerwagen 5 um Gelenkbolzen 21, die in Fahrrichtung des Trägerwagens angeordnet sind, verschwenkbar. In der Ebene senkrecht zur Fahrrichtung ist jede Anschlußgegenplatte entlang der die Gelenkbolzen 21 durchsetzenden Gelenkhebel 20 bis zu einem Anschlag 22 an den Gelenkhebeln verschiebbar. Das über die Gelenkbolzen 21 hinausragende Ende 23 der Gelenkhebel ist unter Zwischenschaltung einer Rückzugfeder 24, die in Richtung des Pfeiles 25 wirkt, am Trägerwagen 5 befestigt. Die Medienleitungen 19, die von den Anschlußgegenstücken des Trägerwagens zu den Blaslanzen führen, weisen Kompensatoren, das sind Faltbälge 30 aus Metall oder Kunststoff etc., auf, die die Schwenk- und Verschiebebewegung der Anschlußgegenplatten 18, 18' gegenüber dem Trägerwagen 5 ermöglichen.The openings of the media supply lines that are not connected to the carrier car or the openings of the non-connected lines in the carrier car can be closed either manually or by means of a remote control by means of dust protection caps (not shown). The mating plates provided on the carrier car 18, 18 'are with articulated lever 20 on the carrier car 5 to hinge pin 21, which in driving Direction of the carrier carriage are arranged, pivotable. In the plane perpendicular to the direction of travel, each connection counterplate can be displaced along the articulated levers 20 passing through the articulated bolts 21 up to a stop 22 on the articulated levers. The end 23 of the articulated lever projecting beyond the articulated bolts 21 is fastened to the carrier carriage 5 with the interposition of a return spring 24 which acts in the direction of the arrow 25. The media lines 19, which lead from the connection counterparts of the carrier carriage to the blowing lances, have compensators, that is bellows 30 made of metal or plastic, etc., which enable the pivoting and displacement movement of the connection counterplates 18, 18 'relative to the carrier carriage 5.

An der Unterseite jeder Anschlußgegenplatte 18, 18' ist jeweils ein spurkranzloses Stützrad 26 montiert, welches auf einer parallel zu den Schienen 9, 10, 11 des Trägerwagens 5 angeordneten Schiene 27 läuft und so jede Anschlußgegenplatte 18, 18' stets in richtiger Höhe zu den ortsfesten Anschlußplatten 16 hält.On the underside of each counter plate 18, 18 'is mounted a non-tracked support wheel 26 which runs on a rail 27 arranged parallel to the rails 9, 10, 11 of the carrier carriage 5 and so each counter plate 18, 18' is always at the correct height stationary connection plates 16 holds.

Jede ortsfeste Anschlußplatte 16 ist mit einem klammerartigen Kupplungsstück 28, welches die am Trägerwagen befestigte Anschlußgegenplatte bei in Blasstellung befindlicher Lanze übergreift, versehen. Das die Anschlußgegenplatte 18 des Trägerwagens umgreifende Ende des Kupplungsstückes 28 ist mit einem hydraulisch betätigbaren Kolben 29 ausgestattet, der bei Beaufschlagung die am Trägerwagen montierte Anschlußgegenplatte 18 entgegen der Wirkung der Federn 24 gegen die ortsfeste Anschlußplatte 16 dichtend anpreßt, wodurch die Medienversorgungsleitungen an die über dem Konverter befindliche Blaslanze angeschlossen sind.Each stationary connection plate 16 is provided with a clamp-like coupling piece 28 which engages over the connection counterplate attached to the carrier carriage when the lance is in the blowing position. The end of the coupling piece 28, which engages around the connection counterplate 18 of the carrier carriage, is equipped with a hydraulically actuable piston 29, which presses the connection counterplate 18 mounted on the carrier carriage against the action of the springs 24 in a sealing manner against the action of the springs 24, whereby the media supply lines to the above the Blow lance converter are connected.

Durch die erfindungsgemäße Einrichtung ist es möglich, für die beiden Konverter 3 und 4, von denen jeweils nur einer in Betrieb ist, mit nur einem einzigen Trägerwagen 5 das Auslangen zu finden. Bei einem Konverterbetrieb mit beispielsweise drei Konvertern, von denen jeweils zwei in Betrieb sind und einer zugestellt wird, genügen erfindungsgemäß zwei Trägerwagen. Die Medienversorgungsleitungen des gerade nicht in Betrieb befindlichen Konverters werden an einem nicht dargestellten Ventilstand abgesperrt. Es ist jedoch auch möglich, für alle Blasstände gemeinsame Medienversorgungsleitungen vorzusehen, die dann an jedem Blasstand absperrbare Anschlußstücke aufweisen.By means of the device according to the invention, it is possible for the two converters 3 and 4, of which only one is in operation, to find sufficiency with only a single carrier car 5. In a converter operation with, for example, three converters, two of which are in operation and one is being delivered, two carrier carriages are sufficient according to the invention. The media supply lines of the converter that is not currently in operation are shut off at a valve stand, not shown. However, it is also possible Provide common media supply lines for all blowing stations, which then have lockable connectors on each blowing station.
