Description

Die Erfindung betrifft einen Transportwagen für metallurgische Transportgefäße, insbesondere Pfannentransportwagen, mit einem Fahrrahmen und einem gegenüber dem Fahrrahmen kippbaren Kipprahmen, wobei zwischen dem Kipprahmen und dem Fahrrahmen mindestens eine Stelleinrichtung vorgesehen ist, die einerseits am Kipprahmen und andererseits am Fahrrahmen angelenkt ist und deren Distanz zwischen den Anlenkpunkten unter Kippung des Kipprahmens veränderbar ist.The invention relates to a transport trolley for metallurgical transport containers, in particular ladle transport trolleys, with a traveling frame and a tilting frame which can be tilted relative to the traveling frame, at least one adjusting device being provided between the tilting frame and the traveling frame, which is articulated on the one hand on the tilting frame and on the other hand on the traveling frame and the distance between them the pivot points can be changed while tilting the tipping frame.

Ein Transportwagen dieser Art ist aus der US-A - 3,858,672 bekannt. Der Kipprahmen, der das metallurgische Transportgefäß umgibt, ist bei diesem bekannten Wagen über eine außermittig vorgesehene Gelenkstelle an dem Fahrrahmen angelenkt. Hierdruch gelingt es, beim Kippen des metallurgischen Transportgefäßes mit dessen Ausgießschnauze über den Grundriß des Wagens hinauszugelangen, so daß die im metallurgischen Transportgeefäß enthaltene Schmelze in ein neben dem Wagen abgestelltes Gefäß fließen kann. Eine Verschmutzung des Transportwagens durch austretende Schmelze kann damit verhindert werden.A trolley of this type is known from US-A-3,858,672. The tilting frame which surrounds the metallurgical transport vessel is articulated on the traveling frame in this known carriage via an articulated joint. This enables the metallurgical transport vessel to be tipped over the floor plan of the wagon with its pouring spout, so that the melt contained in the metallurgical transport vessel can flow into a vessel placed next to the wagon. This prevents contamination of the trolley by the escaping melt.

Zum Kippen des Kipprahmens dient ein einerseits an diesem und andererseits am Fahrrahmen angelenkter Druckmittelzylinder. Nachteilig ist hierbei, daß der Druckmittelzylinder beim Kippen des Kipprahmens große Hubarbeit leisten muß, da der Schwerpunkt des metallurgischen Transportgefäßes infolge der außermittigen Anlenkung des Kipprahmens am Fahrrahmen beim Kippvorgang gehoben werden muß. Ist der beim Kippen des metallurgischen Transportgefäßes von dessen Ausgießschnauze zurückgelegt Weg infolge einer großen Länge des Transportwagens groß zu bemessen, muß die Anlenkung des Kipprahmens am Fahrrahmen entsprechend weit außermittig vorgesehen werden, und es ergibt sich eine besonders große Hubarbeit, die beim Kippen des metallurgischen Transportgefäßes zu leisten ist.A pressure medium cylinder articulated on the one hand on the one hand and on the other on the traveling frame serves to tilt the tilting frame. The disadvantage here is that the pressure medium cylinder has to do a great deal of lifting work when the tipping frame is tilted, since the center of gravity of the metallurgical transport vessel has to be lifted as a result of the eccentric articulation of the tipping frame on the traveling frame during the tipping process. Is that when the metallurgical transport vessel from its pouring spout to travel large due to a large length of the trolley, the articulation of the tipping frame on the traveling frame must be provided correspondingly far off-center, and there is a particularly large amount of lifting work to be done when tipping the metallurgical transport vessel.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, einen Transportwagen der eingangs beschriebenen Art zu schaffen, bei dem beim Kippen des metallurgischen Transportgefäßües um nur einen geringen Winkel ein relativ großer horizontaler Weg von dessen Ausgießschnauze zurückgelegt wird, wobei der Kippvorgang möglichst ohne Hebearbeit, also nur eine möglichst geringe Kraft erfordernd, stattfindet.The invention aims to avoid these disadvantages and difficulties and has as its object to provide a transport trolley of the type described in which a relatively large horizontal path is covered by the pouring spout when the metallurgical transport vessel is tilted by only a small angle, the tilting process if possible without lifting work, i.e. requiring only the lowest possible force.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kipprahmen zwei zueinander parallele Seitenwangen aufweist, die an ihrer Unterseite je eine konvexe Abwälzbahn aufweisen, die jeweils an einer am Fahrrahmen angeordneten, etwa horizontal verlaufenden Gegenabwälzbahn aufliegen, wobei das Verhältnis des Abstandes der Mitte des Transportwagens bis zur maximal erreichbaren Kipplage einer Ausgießschnauze des metallurgischen Transportgefäßes zum Krümmungsradius der Abwälzbahnen der Seitenwangen zwischen 1,5 und 3,5 liegt.This object is achieved in that the tilting frame has two mutually parallel side cheeks, each of which has a convex rolling track on its underside, each of which rests on an approximately horizontal counter-rolling track arranged on the traveling frame, the ratio of the distance from the center of the trolley to to the maximum achievable tipping position of a pouring spout of the metallurgical transport vessel to the radius of curvature of the rolling paths of the side walls is between 1.5 and 3.5.

Aus der DE-C - 24 39 526 ist eine Kippvorrichtung für ein metallurgisches Transportgefäß bekannt, bei der das metallurgische Transportgefäß in einem Kippring eingesetzt ist, der mittels Kippzapfen an einem Fahrgestell eines Transportwagens abgestützt ist, wobei als Kippantrieb ein auf einem Kippzapfen aufgesetztes Getriebe mit Motor vorgesehen ist. Beim Kippen kommt es zu einem Abrollvorgang der Tragzapfen auf dem Wagengestell, so daß das metallurgische Transportgefäß sich während des Entleervorganges in Entleerrichtung bewegt. Bei dieser Konstruktion können jedoch nur geringe horizontale Bewegungen des metallurgischen Transportgefäßes bei sehr großem Kippwinkel erreicht werden. Weiters ist auch infolge des Aufsteckgetriebes, das die Horizontalbewegung während des Kippvorganges mitmacht und das hierbei geführt werden muß, nur ein geringer horizontaler Weg beim Kippen erreichbar.From DE-C - 24 39 526 a tilting device for a metallurgical transport vessel is known, in which the metallurgical transport vessel is inserted in a tilting ring, which is supported by means of tilting pins on a chassis of a transport vehicle, with a gearbox mounted on a tilting pin as the tilting drive Motor is provided. When tipping, there is one Rolling of the trunnion on the carriage frame, so that the metallurgical transport vessel moves in the emptying direction during the emptying process. With this construction, however, only slight horizontal movements of the metallurgical transport vessel can be achieved with a very large tilt angle. Furthermore, due to the slip-on gear, which takes part in the horizontal movement during the tilting process and which must be guided here, only a small horizontal path can be reached when tilting.

Aus dem Ofenbau ist es bekannt (DE-A - 1 804 007), einen metallurgischen Ofen auf konvexen Seitenwangen kippbar zu lagern, jedoch stellt sich dort das Problem der horizontalen Verlagerung der Ausgießschnauze während des Kippvorganges nicht, da metallurgische Öfen weit auskrangende Ausgießschnauzen aufweisen. Zudem sind bei metallurgischen Öfen die Ausgießschnauzen etwa in Höhe des Krümmungsmittelpunktes der Seitenwangen-Abwälzbahnen angeordnet, so daß der von den Ausgießschnauzen beim Kippvorgang zurückgelegte horizontale Weg relativ gering ist.It is known from furnace construction (DE-A-1 804 007) to tilt a metallurgical furnace on convex side cheeks, but the problem of horizontal displacement of the pouring spout during the tilting process does not arise there, since metallurgical furnaces have protruding spouts. In addition, in the case of metallurgical furnaces, the pouring spouts are arranged approximately at the center of curvature of the side cheek rolling tracks, so that the horizontal path covered by the pouring spouts during the tilting process is relatively small.

Ein besonders großer von der Ausgießschnauze des Transportgefäßes zurückgelegter horizontaler Weg ergibt sich beim erfindungsgemäßen Transportwagen, wenn bei aufrechter Stellung des Transportgefäßes der Vertikal-­Abstand des oberen Gefäßrandes bzw. dessen Ausgießschnauze vom unterhalb liegenden Krümmungsmittelpunkt der Abwälzbahnen mindestens halb so groß ist wie der Krümmungsradius.A particularly large horizontal path covered by the pouring spout of the transport vessel is obtained in the trolley according to the invention if, when the transport vessel is in the upright position, the vertical distance of the upper edge of the vessel or its pouring spout from the center of curvature of the rolling tracks below is at least half the radius of curvature.

Vorzugsweise sind die Seitenwangen in Fahrrichtung angeordnet.The side walls are preferably arranged in the direction of travel.

Um ein übermäßiges Kippen des metallurgischen Transportgefäßes zu verhindern, sind zweckmäßig die Seitenwangen mit den Kippwinkel begrenzenden Endanschlägen versehen.In order to prevent excessive tilting of the metallurgical transport vessel, the are expedient Provide the side walls with end stops that limit the tilt angle.

Zur exakten Bewegung der Seitenwangen auf den Abwälzbahnen sind die Seitenwangen vorteilhaft zumindest über einen Teilbereich der Abwälzbahn mit Seitenführungsborden nach der Art eines Spurkranzes versehen sowie sind zweckmäßig zwischen den Seitenwangen und dem Fahrrahmen formschlussig ineinandergreifende, ein Verrutschen der Seitenwangen verhindernde Zahnelemente vorgesehen.For the exact movement of the side cheeks on the rolling tracks, the side cheeks are advantageously provided with side guide rims in the manner of a wheel flange at least over a partial area of the rolling track, and there are expediently interlocking tooth elements between the side cheeks and the travel frame that prevent the side cheeks from slipping.

Um eine einfache Bedienung des Transportwagens zu erzielen, sind vorteilhaft die Seitenwangen mit Zentrierausnehmungen zur Aufnahme von Gefäßtraglaschen des metallurgischen Transportsgefäßes versehen.In order to achieve simple operation of the transport trolley, the side cheeks are advantageously provided with centering recesses for receiving vessel support tabs of the metallurgical transport vessel.

Gemäß einer bevorzugten Ausführungsform ist der Fahrrahmen mehrteilig ausgestaltet und weist einen die Gegenabwälzbahnen aufweisenden einteiligen Oberrahmen sowie mindestens einen die Fahrgestelle aufweisenden Unterrahmen auf, wobei der Oberrahmen auf dem bzw. den Unterrahmen über Wiegemeßzellen abgestützt ist.According to a preferred embodiment, the travel frame is of multi-part design and has a one-piece upper frame which has the counter-rolling tracks and at least one subframe which has the chassis, the upper frame being supported on the subframe or frames via weighing cells.

Hierbei ist es von Vorteil, wenn der Oberrahmen gegenüber dem bzw. den Unterrahmen mittels Stabilisierungslenkern, die sich etwa in Fahrrichtung und etwa quer dazu erstrecken, fixiert ist.It is advantageous here if the upper frame is fixed relative to the lower frame or frames by means of stabilizing links which extend approximately in the direction of travel and approximately transversely thereto.

Die Erfindung ist nachfolgend anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert, wobei Fig. 1 eine Seitenansicht eines Transportwagens, Fig. 2 eine Draufsicht auf den Transportwagen und Fig. 3 eine teilweise geschnittene Stirnansicht des Transportwagens in Richtung des Pfeiles III der Fig. 1 zeigen.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment, wherein FIG. 1 shows a side view of a transport carriage, FIG. 2 shows a top view of the transport carriage, and FIG. 3 shows a partially sectioned end view of the transport carriage in the direction of arrow III in FIG. 1 .

Der Transportwagen weist einen Fahrrahmen 1 auf, der von einem Unterrahmen 2 und einem Oberrahmen 3 gebildet ist. An dem Unterrahmen sind die Fahrgestelle 4 vorgesehen. Der Oberrahmen 3 ruht auf dem Unterrahmen 2 über Wiegemeßzellen 5. Er ist mittels Stabilisierungslenker 6, 7, die sich etwa in Fahrtrichtung 8 und quer dazu erstrecken, gegenüber dem Unterrahmen 2 derart fixiert, daß er zwar geringfügige vertikale Bewegungen gegenüber dem Unterrahmen 2 durchführen kann, jedoch in horizontaler Ebene gegenüber diesem fixiert ist.The trolley has a traveling frame 1, which of a lower frame 2 and an upper frame 3 is formed. The chassis 4 are provided on the subframe. The upper frame 3 rests on the lower frame 2 via weighing cells 5. It is fixed in relation to the lower frame 2 by means of stabilizing links 6, 7, which extend approximately in the direction of travel 8 and transversely thereto, in such a way that it can carry out slight vertical movements relative to the lower frame 2 , but is fixed in a horizontal plane with respect to this.

Auf dem Oberrahmen 3 ruht ein Kipprahmen 9 mittels zweier zueinander paralleler und kongruenter Seitenwangen 10, die sich in Fahrtrichtung 8 erstrecken. Die Seitenwangen 10 weisen konvexe, beim dargetellten Ausführungsbeispiel kreisbogenförmig (mit dem Radius r) gestaltete Abwälzbahnen 11 auf, die auf jeweils an einer am Oberrahmen 3 an dessen Oberseite angeordneten, horizontal verlaufenden Gegenabwälzbahn 12 aufliegen.A tilting frame 9 rests on the upper frame 3 by means of two mutually parallel and congruent side walls 10 which extend in the direction of travel 8. The side cheeks 10 have convex, in the illustrated embodiment, circular arc-shaped (with the radius r) designed rolling tracks 11, each of which rests on a horizontally extending counter-rolling track 12 arranged on the upper frame 3 on its upper side.

In den Kipprahmen 9 ist ein metallurgisches Transportgefäß 13, beim dargestellten Ausführungsbeispiel eine Pfanne, einsetzbar, wobei die Pfannentraglaschen 14 in an der Oberseite der Seitenwangen angeordneten Zentrierausnehmungen 15 ruhen. Zur Durchführung der Kippbewegung des Kipprahmens 9 ist an diesem und am Oberrahmen 3 mindestens ein Druckmittelzylinder 16 angelenkt. Anstelle des Druckmittelzylinders 16 könnten auch andere Antriebsmittel, z. B. eine Zahnstange oder eine Schraubspindel, vorgesehen sein.A metallurgical transport vessel 13, a pan in the exemplary embodiment shown, can be inserted into the tilting frame 9, the pan support brackets 14 resting in centering recesses 15 arranged on the upper side of the side cheeks. In order to carry out the tilting movement of the tilting frame 9, at least one pressure medium cylinder 16 is articulated on it and on the upper frame 3. Instead of the pressure medium cylinder 16, other drive means, for. B. a rack or a screw may be provided.

Um eine einwandfreie Abwälzbewegung der Seitenwangen 10 am Oberrahmen 3 zu sichern, sind die Gegenabwälzbahnen 12 mit Zahnelementen 17 versehen, die in Ausnehmungen 18 der Abwälzbahnen 11 der Seitenwangen 10 eingreifen. Die Zahnelement 17 könnten auch an den Seitenwangen 10 vorgesehen sein. Weiters weisen die Seitenwangen 10 über einen Teilbereich der Abwälzbahnen 11 Seitenführungsborde 19 auf, die die Seitenwangen 10 nach der Art eines Sprukranzes an dem Oberrahmen 3 führen.In order to ensure a perfect rolling movement of the side cheeks 10 on the upper frame 3, the counter-rolling tracks 12 are provided with tooth elements 17 which engage in recesses 18 in the rolling tracks 11 of the side cheeks 10. The tooth element 17 could also be provided on the side cheeks 10. Furthermore, the side cheeks 10 have a partial area of the rolling tracks 11 side guide ridges 19, which guide the side cheeks 10 in the manner of a spruce ring on the upper frame 3.

Zur Begrenzung des Kippwinkels des Kipprahmens 9 ist dieser mit Endanschlägen 20 versehen. Wie aus Fig. 1 ersichtlich, weist der Kipprahmen 9 an seinem hinteren Ende einen sich in Fahrtrichtung 8 erstreckenden Fortsatz 21 auf, der an einer Konsole 22 des Oberrahmens 3 bei aufrechtstehendem metallurgischen Transportgefäß 13 (Position A) aufliegt. Mit Hilfe des Druckmittelzylinders läßt lich der Kipprahmen in die in Fig. 1 strichpunktierten Positionen B und C bewegen. Es ist ersichtlich, daß schon bei Durchführung einer kleinen Kippbewegung des Kipprahmens 9 - d.h. einer Kippbewegung um nur einen kleinen Kippwinkel - die Ausgießschnauze 23 des metallurgischen Transportgefäßes 13 einen relativ großen horizontalen Weg 24 zurücklegt, so daß der Inhalt] des metallurgischen Transportgefäßes 13 in ein in Kipprichtung neben dem Transportwagen abgestelltes Gefäß 25 eingeschüttet werden kann. Das Niveau der im metallurgischen Transportgefäß enthaltenen Flüssigkeit kann daher höhen mäßig knapp unterhalb des Oberrandes 26 des metallurgischen Transportgefäßes 13 liegen. Der erfindungsgemäße Transportwagen eignet sich insbesondere zum Abschlacken von im metallurgischen Transportgefäß enthaltener Metallschmelze.To limit the tilting angle of the tilting frame 9, the latter is provided with end stops 20. As can be seen from FIG. 1, the tilting frame 9 has at its rear end an extension 21 which extends in the direction of travel 8 and which rests on a bracket 22 of the upper frame 3 when the metallurgical transport vessel 13 is upright (position A). With the help of the pressure cylinder, the tilting frame can be moved into the dash-dotted positions B and C in FIG. 1. It can be seen that even with a small tilting movement of the tilting frame 9 - i.e. a tipping movement by only a small tilting angle - the pouring spout 23 of the metallurgical transport vessel 13 covers a relatively large horizontal path 24, so that the contents] of the metallurgical transport vessel 13 can be poured into a vessel 25 placed in the tilting direction next to the transport carriage. The level of the liquid contained in the metallurgical transport vessel can therefore be moderately high just below the upper edge 26 of the metallurgical transport vessel 13. The trolley according to the invention is particularly suitable for slagging molten metal contained in the metallurgical transport vessel.

Ein wesentliches Merkmal der erfindungsgemäßen Vorrichtung ist darin zu sehen, daß der Oberrand 26 des Transportgefäßes bzw. dessen Ausgießschnauze 23 bei aufrecht stehendem metallurgischen Transportgefäß 13 weit oberhalb des Krümmungsmittelpunktes 27 der Abwälzbahnen 11 liegt, wodurch der Effekt, mit einem geringen Kippwinkel einen großen horizontalen Weg 24 der Ausgießschnauze 23 zu erzielen, in besonders effizienter Weise erreicht wird.An essential feature of the device according to the invention can be seen in the fact that the upper edge 26 of the transport vessel or its pouring spout 23, when the metallurgical transport vessel 13 is upright, lies far above the center of curvature 27 of the rolling tracks 11, as a result of which the effect with a small tilting angle is a large horizontal path To achieve 24 the pouring spout 23 is achieved in a particularly efficient manner.

Und zwar beträgt der Vertikal-Abstand h der Ausgießschnauze 23 zum Krümmungsmittelpunkt 27 mindestens die Hälfe des Krümmungsradius r. Ein wesentliches Kriterium zur Erzielung eines großen horizontalen Weges der Ausgießschnauze 23 ist das Verhältnis des Abstandes a der Mitte des Transportwagens bis zur maximal erreichbaren Kipplage der Ausgießschnauze 23 zum Krümmungsradius r der Abwälzbahnen 11, das vorzugsweise zwischen 1,5 und 3,5 liegen soll.The vertical distance h of the pouring spout 23 from the center of curvature 27 is at least half of the radius of curvature r. An important criterion for achieving a large horizontal path of the pouring spout 23 is the ratio of the distance a from the center of the trolley to the maximum achievable tilting position of the pouring spout 23 to the radius of curvature r of the rolling tracks 11, which should preferably be between 1.5 and 3.5.

Die Erfindung beschränkt sich nicht auf das dargestellte Ausführungsbeispiel. So sin beispielsweise auch andere als kreisbogenförmige Abwälzbahnen verwendbar. Auch können sich die Seitenwangen quer zur Fahrtrichtung des Wagens erstrecken, wenn dies erforderlich ist.The invention is not limited to the illustrated embodiment. For example, other rolling paths than circular arcs can also be used. The side walls can also extend transversely to the direction of travel of the car if this is necessary.
