Abstract
Description
Die Erfindung betrifft eine Einrichtung zum Wechseln eines Segmentes eines aus mehreren Segmenten gebildeten Bogens einer Strangführung für eine Stranggießmaschine, auf der flüssige Metalle, insbesondere flüssiger Stahl, vergossen wird, wobei die Segmente einzeln in Segmentträgern lösbar befestigt sind und ein gelöstes Segment in einer Führung mittels einer Kette, einer ersten Traverse und einem Kran bis auf die Gießbühne anhebbar ist.The invention relates to a device for changing a segment of a formed from several segments arc of a strand guide for a Continuous casting machine, on the liquid metals, in particular liquid steel, is cast, the segments individually releasably secured in segment carriers are and a dissolved segment in a guide by means of a chain, a first Traverse and a crane to the casting platform is liftable.
Die Segmente werden insbesondere an Brammen-Stranggießmaschinen eingesetzt
und müssen in Abständen anlässlich von Reparaturen oder / oder
Wartungsarbeiten ausgebaut und in eine entfernte Werkstatt verbracht werden.
Eine solche Segment-Wechseleinrichtung ist in der DE 29 08 476 beschrieben.
Die Segmente tragen Ausbaurollen, die in bis zu einem Bogenradius reichenden
ortsfesten Führungen laufen, die radial zum Bogenverlauf angeordnet sind.
Für alle Führungen ist ein bewegbarer, bis zum Bogenradius reichender, um
eine horizontale Achse schwenkbarer, innerer Bahnabschnitt gebildet, der selektiv
auf eine ortsfeste Führung eingestellt werden kann. Dabei sind einschiebbare
Arretiereinrichtungen für die fluchtende Positionierung und Abstützung des
Bahnabschnitts auf die ortsfesten Führungen vorgesehen. Obwohl sich derartige
Segment-Wechseleinrichtungen bewährt haben, ist wegen der im Bogeninneren
erfolgten Belegung die Zugänglichkeit zu den Segmenten teilweise eingeschränkt.
Außerdem wird die Einsichtnahme behindert.The segments are used in particular on slab continuous casting machines
and must at intervals during repairs or / or
Maintenance work to be expanded and spent in a remote workshop.
Such a segment changing device is described in
Der Erfindung liegt die Aufgabe zugrunde, die Zugänglichkeit zu den Segmenten solcher Stranggießmaschinen zu verbessern, wobei das Gewicht der Segmente, das bis zu 60 t und mehr betragen kann, zu berücksichtigen ist. The invention is based on the object, the accessibility to the segments such continuous casting machines, the weight of the segments, which can be up to 60 t and more, must be taken into account.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Segmentträger über Tragzapfen in einer U-förmigen, zweiten Traverse gehalten ist, deren seitliche Schenkel an je einer Kette hängen. Dadurch kann auf beiden Seiten der Stranggießmaschine auf verschiedenen Niveaus eine verbesserte Begehung mit freier Zugänglichkeit zu den Segmenten erzielt werden. Ein Vorteil ist außerdem die Tragfähigkeit eines solchen Systems in erforderlicher Größenordnung bei freiem Bogen-Innenraum und demzufolge verbesserter Zugänglichkeit zu den Segmenten am Außen- und Innenbogen.The stated object is achieved in that a segment carrier is held by trunnions in a U-shaped, second cross member whose lateral legs hang on one chain each. This can be done on both sides the continuous casting machine at different levels an improved ascent be achieved with free accessibility to the segments. An advantage In addition, the carrying capacity of such a system is of the required order of magnitude with free arch interior and consequently improved accessibility to the segments on the outer and inner bow.
Die Zugänglichkeit wird noch dadurch weiter verbessert, dass eine Begehung zwischen den Segmenten und der Strangführung angeordnet ist.The accessibility is further improved by an inspection is arranged between the segments and the strand guide.
Die Ausbildung der Einrichtung kann ferner derart erfolgen, dass an beiden Stirnseiten der Strangführung, jeweils parallel, dem Verlauf einer Führung folgend, Ausbau-Ketten in jeweils einer oberen Schiene geführt und die Ausbau-ketten am kranseitigen Ende mittels der ersten Traverse, die Kranschlaufen trägt, miteinander verbunden sind.The formation of the device can also be such that at both End sides of the strand guide, each parallel, following the course of a guide, Removal chains are guided in each case in an upper rail and the removal chains at the crane end by means of the first crossbeam, the crane loops carries, are interconnected.
Die hohe Last kann in den Schienen dadurch leichter transportiert werden, dass die Ausbau-Ketten jeweils mittels in den Kettengliedern drehgelagerten Führungsrädern in den Schienen bewegbar sind.The high load can be transported in the rails easier by that the removal chains each by means of rotatably mounted in the chain links guide wheels are movable in the rails.
Für die Übergabe der Segmente ist weiter vorteilhaft, dass die Ausbau-Ketten jeweils beidseitig mit der zweiten Traverse zur Aufnahme eines Segmentes mittels Befestigungsriegeln verbunden sind.For the transfer of the segments is further advantageous that the expansion chains on both sides with the second traverse for receiving a segment are connected by means of fastening bolts.
Für die Übernahme oder den Wiedereinbau ist ferner vorteilhaft, dass die Ausbau-Ketten am segmentseitigen Ende mittels der zweiten Traverse, die Winkelstützen bildet und die Befestigungsriegel aufweist, mit dem Segment verbunden sind. For the acquisition or replacement is also advantageous that the expansion chains at the segment-side end by means of the second traverse, the angle supports forms and has the fastening latch, connected to the segment are.
Eine weitere Ausgestaltung sieht vor, dass eine der Winkelstützen als Momentenstütze auf der zur Stützrollen-Antriebsseite gegenüberliegenden Seite dient und dass das Segment auf dieser Seite mittels zumindest zwei beabstandeten Tragzapfen und eines Riegels und auf der anderen Seite mittels eines Riegels einhängbar ist. Der Vorteil besteht darin, dass das Segment beim Ein- und Ausbau in Richtung des Schienenverlaufs geführt werden kann. Die doppeltgestützte Ausführung berücksichtigt die, insbesondere im oberen Bereich der Stranggießmaschine beim Segmentwechsel auftretenden großen vertikalen Kraftkomponenten bei Segmentgewichten bis zu 60 t.Another embodiment provides that one of the angle brackets as a moment support on the opposite side of the support roller drive side and that the segment on that side is spaced apart by at least two Trunnion and a bolt and on the other side by means of a bolt can be hung. The advantage is that the segment at the input and Removal can be performed in the direction of the rail track. The double-backed Design takes into account, especially in the upper part of Continuous casting machine occurring during segment change large vertical Force components with segment weights up to 60 t.
Eine andere Verbesserung besteht darin, dass am untersten Kettenglied jeder Ausbau-Kette eine gelenkig angeschlossene Einfädelrolle vorgesehen ist. Dadurch werden zum Ausbau eines Segmentes die Ketten von der Gießbühne aus mittels des Krans in die Führungsschienen leichter eingefädelt.Another improvement is that at the bottom chain link everyone Removal chain is provided a hinged threading Einfädelrolle. Thereby The chains from the casting platform are used to remove a segment Threaded easier by means of the crane in the guide rails.
Eine andere Ausgestaltung besteht darin, dass auf beiden Seiten der Strangführung freie Begehungs-Flächen mit freier Zugänglichkeit zu den Segmenten vorgesehen sind. Dadurch werden Wartung und Beobachtung der Anlagenteile begünstigt.Another embodiment is that on both sides of the strand guide free access areas with free accessibility to the segments are provided. This will provide maintenance and monitoring of plant components favored.
Dabei können die Begehungsflächen eine Mindestbreite von 500 mm aufweisen, so dass sogar kleinere Lasten bis zu den Segmenten getragen werden können.The walkways can have a minimum width of 500 mm, so even smaller loads are carried to the segments can.
