Abstract

A method and installation is disclosed for the replacement of a bottom closure of a track-mounted pugh-type transfer ladle having a transfer container supported by two longitudinally spaced-apart bogies which are pivotally attached to the transfer container for swinging movement about a vertical axis, the transfer container having a removable bottom closure located between said bogies. The ladle is moved longitudinally of itself and the two bogies are directed on to different tracks which are spaced from each other to thereby swing the bogies relative to the transfer container and increase the longitudinal space between the bogies; and thereafter the closure is replaced from below through the resulting increased space.

Description

Die Erfindung betrifft ein Verfahren zum Auswechseln von Schieberverschlüssen an schienengebendenen Torpedopfannen nach dem Oberbegriff von Anspruch 1.The invention relates to a method for replacing slide closures on rail-providing torpedo pans according to the preamble of claim 1.

Bis heute ist es üblich, Torpedopfannen der vorgenannten Art, welche den Transport von Roheisen von dem Hochofen zum gegebenenfalls relativ weit entfernten Stahlwerk übernehmen, um ihre Längsachse drehbar auszubilden, damit die Entleerung durch die Einfüllöffnung hindurch erfolgen kann. Bei einer grösseren Anzahl von unterschiedlichen, in der Stahlerzeugung oder Verarbeitung verwendeten Gefässen und Pfannen sind im Laufe der Zeit absperrbare Bodenauslässe vorgesehen worden, womit auf die Kippbarkeit verzichtet werden konnte. Mit dem Durchbruch des Schieberverschlusses in der Praxis hat sich diese Entwicklung beschleunigt fortgesetzt. Damit liess sich durch Wegfall der beweglichen Lagerung und des Antriebes nicht nur der bauliche Aufwand reduzieren, sondern die Entleerung durch den Bodenauslass brachte die im Vergleich zur Entleerung über eine Giessschnauze erheblichen betrieblichen Vorteile. Obwohl vergleichbare Vorteile auch bei Torpedopfannen zu erzielen wären, ist bis anhin mit Bodenauslässen nicht gearbeitet worden. Der Anwendung von Schieberverschlüssen stellen sich jedenfalls aus der Tatsache, dass diese zur Erneuerung der verschleissenden Feuerfestteile relativ häufig ausgewechselt werden müssen, erhebliche Probleme in den Weg.To date, it is common to use torpedo pans of the aforementioned type, which take over the transport of pig iron from the blast furnace to the steelworks, which may be relatively distant, in order to make their longitudinal axis rotatable, so that emptying can take place through the filling opening. With a large number of different vessels and pans used in steel production or processing, lockable floor outlets have been provided over the course of time, making it possible to dispense with the tiltability. With the breakthrough of the slide lock in practice, this development has accelerated. By eliminating the movable bearing and the drive, this not only reduced the structural effort, but emptying through the floor outlet brought considerable operational advantages compared to emptying via a pouring spout. Although comparable advantages could also be achieved with torpedo pans, floor outlets have not yet been used. In any case, the use of slide closures is hampered by the fact that they have to be replaced relatively frequently to replace the wearing refractory parts.

Wegen des grossen Gewichtes von Torpedopfanne und Inhalt muss zur Vermeidung übermässiger Achslasten mit einer grossen Anzahl von Fahrwerksachsen gearbeitet werden. Die Fahrwerkseinheiten nehmen dabei praktisch die -ganze Länge der Torpedopfanne in Anspruch. Während zwar zwischen den benachbarten Enden der Fahrwerkseinheiten genügend Platz für den Schieberverschluss selbst besteht, ist dessen Zugänglichkeit zum Zwecke des Austausches nicht oder in nicht ausreichendem Masse gegeben.Because of the great weight of the torpedo pan and its contents, a large number of undercarriage axles must be used to avoid excessive axle loads. The chassis units practically take up the entire length of the torpedo pan. While there is enough space between the adjacent ends of the undercarriage units for the slide closure itself, its accessibility for the purpose of replacement is not given or is insufficient.

Mit dem Ziel, den Betrieb von Torpedopfannen durch Verwendung von Schieberverschlüssen zu vereinfachen, soll nun die Aufgabe gelöst werden, das Auswechseln von Schieberverschlüssen an Torpedopfannen zu ermöglichen. Erfindungsgemäss geschieht dies durch die Massnahmen nach dem Kennzeichen von Anspruch 1. Durch die gleichsinnige Verschwenkung der Fahrwerkseinheiten bezüglich der Längsachse der Torpedopfanne werden die inneren Enden dieser Fahrwerkseinheiten aus dem Bereich enfernt, welcher der Längsmitte der Pfanne bzw. einem dort angeordneten, einen Bodenauslass absperrenden Schieberverschluss benachbart ist. Die Entfernung erfolgt dabei nach entgegengesetzten Seiten und ist umso grösser je grösser der Abstand zwischen den Schienensträngen ist.With the aim of simplifying the operation of torpedo pans by using slide closures, the task is now to be solved to enable the replacement of slide closures on torpedo pans. According to the invention, this is done by the measures according to the characterizing part of claim 1. By pivoting the chassis units in the same direction with respect to the longitudinal axis of the torpedo pan, the inner ends of these chassis units are removed from the area which is the longitudinal center of the pan or a slide closure arranged there and blocking a floor outlet is adjacent. The distance is on opposite sides and the greater the distance between the rail tracks, the greater the distance.

Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens, welche sich durch die Massnahmen des Kennzeichens von Anspruch 2 auszeichnet. Da der Abstand zwischen den beiden benachbarten Schienensträngen, welche vorzugsweise parallel verlaufen, frei gewählt werden kann und auf jeden Fall erheblich grösser ist als die Spurweite kann die Auswechselstation eine Arbeitsgrube umfassen, deren Breite nicht durch den Schienenabstand begrenzt ist und die Zugänglichkeit des Schieberverschlusses von unten erheblich verbessert.The invention also relates to a device for carrying out the method, which is characterized by the measures of the characterizing part of claim 2. Since the distance between the two adjacent rail tracks, which preferably run parallel, can be freely selected and in any case is considerably larger than the track width, the exchange station can include a working pit, the width of which is not limited by the rail spacing and the accessibility of the slide lock from below significantly improved.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles einer Einrichtung zur Durchführung des Verfahrens wird nachfolgend die Erfindung näher erläutert. Es zeigen :

  • Figur 1, eine schematische Aufrissdarstellung einer schienengebundenen Torpedopfanne ;
  • Figur 2, die Einrichtung nach dem Ausführungsbeispiel im Grundriss, mit einer auf der Auswechselstation befindlichen Torpedopfanne nach Figur 1 ;
  • Figur 3, einen Schnitt entlang Linie 111-111 in Figur 2 ; und
  • Figur 4, einen Vertikalschnitt durch einen an einer Torpedopfanne befestigten Schieberverschluss.
The invention is explained in more detail below on the basis of an exemplary embodiment of a device for carrying out the method shown in the drawing. Show it :
  • Figure 1 is a schematic elevation of a rail bound torpedo pan;
  • Figure 2, the device according to the embodiment in plan, with a torpedo pan located on the replacement station of Figure 1;
  • Figure 3 shows a section along line 111-111 in Figure 2; and
  • Figure 4, a vertical section through a slide fastener fastened to a torpedo pan.

In der Zeichnung ist mit 2 allgemein eine schienengebundene Torpedopfanne bezeichnet, welche ein Torpedogefäss 4 und zwei Drehgestellfahrwerke 6 umfasst. Die Drehgestellfahrwerke 6 stützen Träger 8 ab, welche Enden des Torpedogefässes 4 starr, d. h. undrehbar, aufnehmen. In der Längsmitte des Torpedogefässes 4 ist an dessen Unterseite ein Schieberverschluss angeordnet, der allgemein mit 10 bezeichnet ist, und welcher, wie sich aus Figur 3 ergibt, einen Bodenauslass 12 des Torpedogefässes beherrscht. Zwischen den einander zugekehrten Enden der Fahrwerks 6 verbleibt ein Abstand Y, welcher normalerweise nicht ausreicht, um den Schieberverschluss 10 vom Torpedogefäss 4 zu entfernen und durch einen erneuerten Schieberverschluss zu ersetzen.In the drawing, 2 generally denotes a rail-bound torpedo pan, which comprises a torpedo vessel 4 and two bogie bogies 6. The bogie bogies 6 support beams 8, which ends of the torpedo tube 4 rigid, i. H. rotatable, record. In the longitudinal center of the torpedo tube 4, a slide closure, which is generally designated 10, is arranged on its underside and, as can be seen from FIG. 3, controls a bottom outlet 12 of the torpedo tube. Between the mutually facing ends of the undercarriage 6 there remains a distance Y which is normally not sufficient to remove the slide closure 10 from the torpedo vessel 4 and to replace it with a renewed slide closure.

Erfindungsgemäss wird nun der Abstand zwischen den inneren Enden der Fahrwerks 6 auf ein Mass z dadurch vergrössert, dass die Fahrwerke bezüglich der Längsachse 14 des Torpedogefässes 4 im gleichen Drehsinn verschwenkt werden, wie dies in Fig. 2 dargestellt ist. Die Verschwenkung wird dadurch bewerkstelligt, dass eines der Fahrwerke 6 von einem ersten Schienenstrang 16 auf einen zweiten Schienenstrang 18 überführt wird, der im Abstand zu diesem verläuft. Wie sich aus Figur 2 ergibt, erstreckt sich der zweite Schienenstrang 18 parallel zum ersten Schienenstrang 16 und ist mit diesem über ein Zwischenstück 20 und eine Weiche 22 verbunden. In der dargestellten Anordnung ist das beim Verfahren der Torpedopfanne 2 auf dem Schienenstrang 16 vorlaufende Fahrwerk über die Weiche auf den Schienenstrang 18 abgelenkt worden, während das in Verschieberichtung nachlaufende Fahrwerk auf dem Schienenstrang 16 verblieben ist.According to the invention, the distance between the inner ends of the undercarriage 6 is now increased to a dimension z in that the undercarriages are pivoted in the same direction of rotation with respect to the longitudinal axis 14 of the torpedo vessel 4, as is shown in FIG. 2. The pivoting is accomplished in that one of the undercarriages 6 is transferred from a first rail track 16 to a second rail track 18, which runs at a distance from the latter. As can be seen from FIG. 2, the second rail track 18 extends parallel to the first rail track 16 and is connected to it via an intermediate piece 20 and a switch 22. In the arrangement shown, the running gear on the rail track 16 when the torpedo pan 2 is moved is via the switch to the rail track 18 has been deflected while the undercarriage trailing in the direction of displacement has remained on the rail track 16.

Mit 24 ist allgemein eine Auswechselstation bezeichnet, welche, wie aus Figur 3 besser zu entnehmen ist, eine längliche Arbeitsgrube 26 aufweist, die sich zwischen den Schienensträngen 16 und 18 parallel erstreckt. In der Arbeitsgrube 6 ist ein auf Schienen 28 verschiebbarer Rolltisch 30 verfahrbar, der einen Hubmechanismus 32 aufweist. Der Hubmechanismus des Rolltisches 30 gestattet, einen vom Torpedogefäss 4 gelösten Schieberverschluss 10 abzustützen und abzusenken, wobei nach Absenkung des auf dem Rolltisch befindlichen Schieberverschlusses dieser aus dem Bereich unterhalb des Torpedogefässes 4 über die Schienen 28 herausgefahren werden kann. Ein bereitgestellter erneuerter Schieberverschluss kann in entsprechender Weise unter das Gefäss.. verbracht und bis zur Befestigung an diesem unterstützt werden.24 generally designates an exchange station which, as can be seen better from FIG. 3, has an elongated working pit 26 which extends in parallel between the rail tracks 16 and 18. In the working pit 6, a roller table 30 which can be moved on rails 28 and which has a lifting mechanism 32 can be moved. The lifting mechanism of the roller table 30 allows a slide closure 10 detached from the torpedo container 4 to be supported and lowered, and after the slide closure located on the roller table has been lowered, it can be moved out of the area below the torpedo container 4 via the rails 28. A renewed slide closure provided can be placed under the vessel in a corresponding manner and supported until it is attached to it.

Wie aus den Figuren 2 und 3 deutlich wird, kann für das Auswechseln des Schieberverschlusses 10 am Torpedogefäss 4 in der beschriebenen Weise ausreichend Platz zwischen den Fahrwerken 6 geschaffen werden. Bei gegebenen Längenverhältnissen der Torpedopfanne 2 lässt sich der Abstand z zwischen den gleichsinnig verschwenkten Fahrwerkseinheiten 6 durch den Abstand der Schienenstränge 16, 18. bestimmen.As is clear from FIGS. 2 and 3, sufficient space can be created between the undercarriages 6 for the replacement of the slide closure 10 on the torpedo vessel 4 in the manner described. Given the length ratios of the torpedo pan 2, the distance z between the chassis units 6 pivoted in the same direction can be determined by the distance between the rail tracks 16, 18.

In Figur 4 ist ein üblicher Schienenverschluss in am Torpedogefäss 4 befestigten Zustand dargestellt, wobei aus dieser Darstellung auch die Platzverhältnisse zwischen den Fahrwerken ersichtlich sind. Der eine Mauerung 40 umfassende metallische Mantel 42 des Torpedogefässes enthält eine Befestigungsplatte 44, die mit einer Anzahl von paarweise angeordneten, nach unten gerichteten Befestigungsbolzen 46 ausgerüstet ist. Die Befestigungsbolzen 46 durchsetzen Bohrungen im Gehäuseteil 48 des Schieberverschlusses, wobei Keile 50, die ihrerseits die Befestigungsbolzen 46 durchdringen, das Schiebergehäuse 48 gegen die Befestigungsplatte 44 pressen. Mit dem Gehäuse 48 bildet ein Deckel 52, sowie ein beweglicher Schieberteil 54 eine Baueinheit, wobei in das Gehäuse eine Bodenplatte 56 eingelassen ist, währenddem der Schieberteil 52 eine Schieberplatte 58 und eine Ausgusshülse 60 enthält. Im dargestellten offenen Zustand des Schieberverschlusses steht die Bohrung 62 in der Ausgusshülse mit der von einem Ausgussstein 64 begrenzten Bodenöffnung 66 im Torpedogefäss 4 in Verbindung.A conventional rail closure is shown in FIG. 4 in the state attached to the torpedo vessel 4, the space available between the undercarriages also being apparent from this illustration. The metallic casing 42 of the torpedo tube, which comprises a wall 40, contains a fastening plate 44 which is equipped with a number of fastening bolts 46 arranged in pairs and pointing downwards. The fastening bolts 46 pass through bores in the housing part 48 of the slide closure, wedges 50, which in turn penetrate the fastening bolts 46, press the slide housing 48 against the fastening plate 44. A cover 52 and a movable slide part 54 form a structural unit with the housing 48, a base plate 56 being let into the housing, while the slide part 52 contains a slide plate 58 and a pouring sleeve 60. In the open state of the slide closure shown, the bore 62 in the pouring sleeve is connected to the bottom opening 66 in the torpedo vessel 4, which is delimited by a pouring stone 64.

Der Schieberverschluss 10 wird dadurch vom Torpedogefäss 4 entfernt, dass die Keile 50 aus den Befestigungsbolzen 46 herausgetrieben werden, wonach dieser von den Befestigungsbolzen 46 durch Herunterfahren abgenommen werden kann.The slide closure 10 is removed from the torpedo cup 4 by driving the wedges 50 out of the fastening bolts 46, after which this can be removed from the fastening bolts 46 by lowering them.

Die Durchführung dieser Arbeiten ist dann möglich, wenn die Fahrwerke 6 - im Gegensatz zu der in Figur 4 gezeigten, bezüglich des Torpedogefässes 4 nicht verschwenkten Stellung - die in Figur 2 dargestellte Lage einnehmen. Es steht dann für den Zugang zum Schieberverschluss 10 der Abstand z zur Verfügung, der erheblich grösser als der Abstand y ist. Demzufolge ist das Heraustreiben der Keile 50 auch dann möglich, wenn der Hubmechanismus 32 sich unter dem Schieberverschluss 10 befindet, um dessen Gewicht - in der Grössenordnung von 2 500 kg liegend - abzufangen. Auch der Schieberverschluss 10 lässt sich dann ohne Behinderung durch die Fahrwerke 6 absenken und durch einen erneuerten Schieberverschluss ersetzen.This work can be carried out when the undercarriages 6 - in contrast to the position shown in FIG. 4 and not pivoted with respect to the torpedo vessel 4 - assume the position shown in FIG. The distance z, which is considerably larger than the distance y, is then available for access to the slide closure 10. As a result, the wedges 50 can also be driven out when the lifting mechanism 32 is located under the slide closure 10 in order to absorb its weight, which is of the order of 2,500 kg. The slide lock 10 can then also be lowered without hindrance by the running gear 6 and replaced by a renewed slide lock.
