Description
Die Erfindung betrifft einen Tragturm für metallurgische Gefäße verschiedener Abmessungen, insbesondere für unterschiedlich große Gießpfannen bei einer Stranggießanlage, mit mindestens einem von einer Tragsäule auskragenden Tragarm der zwei das metallurgische Gefäß seitlich umgreifende Stützarme aufweist, an denen bewegbare Auflagen für an den metallurgischen Gefäßen vorgesehene Trageinrichtungen vorgesehen sind.The invention relates to a support tower for metallurgical vessels of different dimensions, in particular for casting ladles of different sizes in a continuous casting installation, with at least one support arm projecting from a support column which has two support arms which laterally encompass the metallurgical vessel and on which movable supports are provided for support devices provided on the metallurgical vessels are.
In Hüttenbetrieben sind in der Regel metallurgische Gefäße, insbesondere Gießpfannen, unterschiedlicher Dimensionierung oder unterschiedlicher konstruktiver Gestaltung für denselben Zweck in Verwendung. Insbesondere beim Stranggießen werden die als Vorratsbehälter dienenden metallurgischen Gefäße (Gießpfannen) von einem Tragturm mit auskragendem Tragarm getragen. Der Tragarm weist zwei das metallurgische Gefäß seitlich umgreifende Stützarme auf, an denen jeweils eine Auflage für eine am metallurgische Gefäß vorgesehene Trageinrichtung, wie eine Traglasche einer Gießpfanne, vorgesehen ist. Mit einem solchen Tragturm ist man an die Verwendung von metallurgischen Gefäßen ganz bestimmter Größe und Bauart gebunden, die durch den Abstand der beiden an den Stützarmen vorgesehenen Auflagen, deren Querschnittsform sowie deren Höhenlage vorgegeben ist. Dies ist für einen kontinuierlich ablaufenden Gießbetrieb, insbesondere Stranggießbetrieb, nachteilig. Ein weiterer Nachteil ist darin zu sehen, daß es dadurch nicht möglich ist, die im Hüttenbetrieb im allgemeinen zum Gefäßtransport eingesetzten fahrbaren Krane unterschiedlicher Baugröße und Tragkraft optimal einzusetzen und auszunützen.In metallurgical plants, metallurgical vessels, in particular ladles, of different dimensions or different structural designs are generally used for the same purpose. In the case of continuous casting in particular, the metallurgical vessels (ladles) serving as storage containers are carried by a support tower with a cantilevered support arm. The support arm has two support arms which laterally encompass the metallurgical vessel, on each of which a support is provided for a support device provided on the metallurgical vessel, such as a support tab of a ladle. With such a support tower, one is bound to the use of metallurgical vessels of a very specific size and design, which is determined by the distance between the two supports provided on the support arms, their cross-sectional shape and their height. This is disadvantageous for a continuously running casting operation, in particular a continuous casting operation. Another disadvantage is that it does not make it possible to optimally use and utilize the mobile cranes of various sizes and load capacities that are generally used for vessel transport in hut operations.
Zur Vermeidung dieser Nachteile ist es aus der DE-B2-2408951 bekannt, neben den an den Stützarmen starr angeordneten Auflagen jeweils eine weitere Auflage vorzusehen, die gegenüber der starren Auflage am Stützarm schwenkbar gelagert ist und mittels eines Schwenkantriebes aus einer zurückgeschwenkten Stellung in eine vorgeschwenkte Stellung zur Aufnahme einer kleinen Gießpfanne bewegt werden kann. Diese bekannte Konstruktion weist den Nachteil auf, daß es aus Platzgründen nicht möglich ist, den Tragturm für mehr als zwei unterschiedlich große metallurgische Gefäße zu verwenden. Weiters ist es nicht möglich, metallurgische Gefäße auf den Tragturm aufzusetzen, die mit ihren Trageinrichtungen zum Teil in die starren Auflagen ragen, von diesen jedoch nicht zur Gänze erfaßt werden können.To avoid these disadvantages, it is known from DE-B2-2408951 to provide, in addition to the supports rigidly arranged on the support arms, in each case a further support which is pivotably mounted on the support arm relative to the rigid support and is pivoted from a pivoted-back position into a pivoted-forward position by means of a pivoting drive Position to accommodate a small ladle can be moved. This known construction has the disadvantage that it is not possible for space reasons to use the support tower for more than two different sized metallurgical vessels. Furthermore, it is not possible to place metallurgical vessels on the support tower, some of which protrude into the rigid supports with their support devices, but cannot be fully grasped by them.
Die Erfindung stellt sich daher die Aufgabe, einen Tragturm der eingangs beschriebenen Art zu schaffen, der die Verwendung beliebig unterschiedllicher metallurgischer Gefäße an ein und demselben Tragarm des Tragturmes ermöglicht.The invention therefore has as its object to provide a support tower of the type described in the introduction, which enables the use of any number of different metallurgical vessels on one and the same arm of the support tower.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeder Stützarm mit mindestens zwei unterschiedlichen, gegeneinander austauschbaren Auflagen versehen ist, die jeweils an einem gemeinsamen, gegenüber dem Stützarm bewegbaren Tragkörper angeordnet sind.This object is achieved in that each support arm is provided with at least two different, mutually interchangeable supports, which are each arranged on a common support body that is movable relative to the support arm.
Nach einer bevorzugten Ausführungsform sind die Tragkörper um eine vertikale, am jeweiligen Stützarm vorgesehene Achse drehbar gelagert.According to a preferred embodiment, the support bodies are rotatably mounted about a vertical axis provided on the respective support arm.
Um auch höhenmäßig unterschiedliche Gießpfannen bei Stranggießanlagen verwenden zu können, wobei die Distanz zwischen Badspiegel in dem unterhalb der Gießpfanne angeordneten Gefäß und dem Gießpfannenauslaß - bei unveränderter Höhenstellung der Gießpfannen - stets gleich groß sein soll, sind zweckmäßig die Auflagen jedes Stützarmes in unterschiedlicher Höhenlage am Tragkörper angeordnet.In order to be able to use ladles of different heights in continuous casting plants, whereby the distance between the bath level in the vessel arranged below the ladle and the ladle outlet - with the ladle level unchanged - should always be the same size, the supports of each support arm are expedient at different heights on the supporting body arranged.
Nach einer anderen bevorzugten Ausführungsform weisen die Auflagen jedes Stützarmes untereinander unterschiedliche Querschnittsformen auf, die mit entsprechend unterschiedlich geformten Trageinrichtungen der metallurgischen Gefäße in Eingriff bringbar sind.According to another preferred embodiment, the supports of each support arm have different cross-sectional shapes from one another, which can be brought into engagement with correspondingly differently shaped support devices of the metallurgical vessels.
Um Gießpfannen mit unterschiedlichen Durchmessern verwenden zu können, sind zweckmäßig die Auflagen jedes Stützarmes am Tragkörper in unterschiedlichen Entfernungen von der Drehachse des Tragkörpers angeordnet.In order to be able to use ladles with different diameters, the supports of each support arm on the support body are expediently arranged at different distances from the axis of rotation of the support body.
Der Antrieb für die drehbaren Tragkörper kann in verschiedener Art ausgeführt sein, wobei es sich jedoch als besonders vorteilhaft erwiesen hat, wenn an dem Tragarm ein Motor montiert ist, der zum synchronen Drehen der Tragkörper mit diesen über Antriebswellen verbunden ist.The drive for the rotatable support body can be designed in various ways, but it has proven to be particularly advantageous if a motor is mounted on the support arm and is connected to the support body for synchronous rotation thereof via drive shafts.
Die Erfindung ist an drei Ausführungsformen anhand der Zeichnung näher erläutert, wobei die Fig. 1, 3 und 5 eine teilweise geschnittene Seitenansicht eines Tragturmes gemäß jeweils einer Ausführungsform und die Fig. 2, 4 und 6 je eine zugehörige Draufsicht auf die in den Fig. 1, 3 und 5 dargestellten Tragtürme zeigen.The invention is explained in more detail in three embodiments with reference to the drawing, FIGS. 1, 3 and 5 being a partially sectioned side view of a support tower in accordance with one embodiment and FIGS. 2, 4 and 6 each an associated plan view of the one in FIGS. 1, 3 and 5 show the support towers shown.
Bei der in den Fig. 1 und 2 dargestellten Ausführungsform weist der Tragturm zwei um eine Säule 1 unabhängig voneinander verschwenkbare gekröpfte Tragarme 2, 3 auf. Jeder der Tragarme 2, 3 besitzt zwei ein - hier nicht dargestelltes - metallurgisches Gefäß seitlich umgreifende Stützarme 4, 5, an deren vorderen Enden 6 jeweils ein um eine vertikale Achse 7 drehbarer Tragkörper 8 montiert ist. Jeder dieser Tragkörper 8 weist einen im Stützarm 4, 5 mittels eines Achsialradiallagers 9 und eines Radiallagers 10 gelagerten Zapfen 11 auf, der an seinem unteren Ende mit einem an ihm starr befestigten Zahnrad 12 versehen ist. In der Draufsicht ist jeder Tragkörper 8 etwa dreieckförmig gestaltet. An jeder der drei Seiten des Tragkörpers ist jeweils eine Pfannenaufnahme 13, 14, 15 vorgesehen, wobei die Pfannenaufnahme jedes Tragkörpers sich untereinander in dreierlei Hinsicht unterscheiden: Die Pfannenaufnahmen 13, 14, 15 weisen unterschiedliche Querschnittsformen auf, sie sind in unterschiedlichen Entfernungen 16, 17, 18 von der Achse 7 des Tragkörpers 8 angeordnet (Fig. 2) und sie sind weiters in unterschiedlichen Höhenlagen 19, 20, 21, wie aus Fig. 1 ersichtlich, am Tragkörper 8 angeordnet. Zwischen den Pfannenaufnahmen 13,14,15 und am Tragkörper 8 vorgesehenen und mit ihm integral ausgebildeten diese Pfannenaufnahmen unterstützenden Konsolen 22, 23, 24 ist jeweils ein stoßdämpfendes Element 25 eingebaut.In the embodiment shown in FIGS. 1 and 2, the support tower has two
Um die Tragkörper 8 in einfacher Weise drehen zu können, ist an jedem Tragarm 2, 3 ein Motor 26 montiert, der mit beiden Tragkörpern 8 des Tragarmes 2, 3 mittels schematisch dargestellter Antriebswellen 27 und Eckgetriebe 28 verbunden ist, wobei die letzte Antriebswelle mit einem Zahnrad in das am unteren Ende des Zapfens 11 montierte Zahnrad 12 eingreift. Wie aus Fig. 2 ersichtlich ist, sind die Tragkörper 8 untereinander gleich ausgebildet, so daß sie, um jeweils zwei einander entsprechende Pfannenaufnahmen 13, 14, 15 nach innen, d. h. zwischen die Stützarme 4, 5 zu schwenken, synchron gedreht werden können.In order to be able to rotate the
Gemäß der Ausführungsform nach den Fig. 1 und 2 ist es möglich, drei verschiedene Gießpfannen an demselben Tragarm 2, 3 des Tragturmes verwenden zu können, wobei sich die Gießpfannen hinsichtlich ihrer Traglaschen, ihrer Durchmesser und ihrer Höhen unterscheiden können. Es muß lediglich das der jeweils verwendeten Gießpfanne entsprechende Paar der Aufnahmen 13, 14, 15 nach innen, d. h. in zueinander fluchtende Stellung gedreht werden.According to the embodiment according to FIGS. 1 and 2, it is possible to use three different ladles on the
Bei der in den beiden Fig. 3 und 4 bzw. 5 und 6 dargestellten Ausführungsform sind die beiden Tragarme 29, 30 bzw. 31, 32 nicht unabhängig voneinander, sondern infolge ihrer integralen Ausbildung nur gemeinsam miteinander schwenkbar. Die Ausführungsform gemäß den Fig. 3 und 4 weist ebenfalls für jeden Tragarm einen eigenen Motor 26 auf.In the embodiment shown in FIGS. 3 and 4 or 5 and 6, the two support

Durch Einschalten einer der Schaltkupplungen 34 oder 34' wird die andere automatisch ausgeschaltet.In the embodiment shown in FIGS. 6 and 6, a
Der Tragturm gemäß den Fig. 5 und 6 ist mit seiner Säule 35 in eine diese umgebende Führungssäule 36 eingesetzt und mittels eines Hubzylinders 37 heb- und senkbar. Der Antrieb zum Schwenken der Tragarme ist mit 38 bezeichnet.The support tower according to FIGS. 5 and 6 is inserted with its
In Fig. sind mit strichlierten Linien unterschiedlich große Pfannen 39, 40, 41 dargestellt, wie sie bei diesem Tragturm verwendet werden können. Die Abstände 42, 43, 44 von den Mittellinien 45, 46, 47 der Trageinrichtungen 48, 49, 50 dieser unterschiedlichen Pfannen 39,40,41 bis zu ihrer Mittellinie 51 ist jeweils unterschiedlich. Aus dieser Fig. 5 ist weiter ersichtlich, daß sich die Böden 52, 53, 54 dieser unterschiedlichen Pfannen 39, 40, 41 in gleicher Höhe 55 befinden, so daß die Distanz 56 zwischen dem sich unterhalb der jeweils verwendeten Gießpfanne 39 oder 40 oder 41 befindlichen Zwischengefäß 57 und dem Boden 52 oder 53 oder 54 der Gießpfanne (bei sich in gleicher Höhenlage befindlichen Tragarmen 31, 32) stets gleich groß ist.In Fig. Are shown with dashed lines different sized
Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt, sondern kann in verschiedener Hinsicht modifiziert werden. So ist es möglich, auch nur zwei oder mehr als drei Pfannenaufnahmen an jedem Tragkörper vorzusehen. Der Drehantrieb für die Tragkörper kann auch von Hand aus erfolgen. Er kann aber auch elektrisch-mechanisch, hydraulisch-mechanisch oder pneumatisch-mechanisch erfolgen.The invention is not restricted to the exemplary embodiments shown, but can be modified in various ways. So it is possible to provide only two or more than three socket receptacles on each support body. The rotary drive for the support body can also be done by hand. However, it can also be carried out electrically-mechanically, hydraulically-mechanically or pneumatically-mechanically.
