Abstract
Description
Die Erfindung betrifft einen Drehturm, insbesondere zur Verwendung in Stranggießanlagen und für Gießpfannen und / oder Verteilerrinnen, mit einer auf einem Fundament angeordneten, sockelartigen Stützkonstruktion, auf der ein oder mehrere Schwenkarme mit Aufnahmemitteln mittels einer Rollendrehverbindung oder einer Kugeldrehverbindung gelagert sind und mittels eines Drehantriebs in Schwenkstellungen drehbar sind.The invention relates to a rotating tower, in particular for use in continuous casting plants and for ladles and / or distribution channels, with one on a foundation arranged, base-like support structure on which one or more Swivel arms with receiving means by means of a roller slewing ring or Ball slewing ring are mounted and by means of a rotary drive in swivel positions are rotatable.
Ein derartiger Drehturm ist z.B. aus der DE 20 44 979 oder der DE - AS 19 63 147 bekannt. Da für kontinuierliches Gießen solche Drehtürme unverzichtbar sind, müssen erhebliche Investitionskosten aufgewendet werden. Für das Schwenken der leeren Gießpfanne gegen eine neue, gefüllte Gießpfanne oder für das Einsetzen einer neu zugestellten und vorgeheizten Verteilerrinne gegen eine verschlissene Verteilerrinne, richten sich die grundsätzlichen Investitionskosten nach den Gestehungskosten für einen Hydraulikmotor, eine Kupplung, ein Planetengetriebe, ein Zahnritzel und eine Rollendrehverbindung mit einer Außenverzahnung, in die das Zahnritzel eingreift. Zusätzlich sind eine Fettschmiereinrichtung und ein außerhalb angeordnetes Antriebsschutzhaus erforderlich. Die hier auflaufenden Kosten werden weiterhin wegen der geforderten Verfügbarkeit des Drehturms durch Reserveteile, zumindest für die verschleißenden Elemente, erhöht. Weiterhin bildet die Entsorgung des verbrauchten Fettes ein nicht zu unterschätzendes Problem. Such a turret is e.g. from DE 20 44 979 or DE - AS 19 63 147 known. As such turrets are indispensable for continuous casting, must considerable investment costs are expended. For swiveling the empty one Ladle against a new, filled ladle or for inserting one newly delivered and preheated distribution channel against a worn distribution channel, The basic investment costs are based on the production costs for a hydraulic motor, a clutch, a planetary gear, a pinion and a roller slewing ring with external teeth into which the pinion intervenes. In addition, a grease lubrication device and one located outside Drive protection house required. The costs accrued here will continue because of the required availability of the turret through spare parts, at least for the wearing elements, increased. Furthermore, the disposal of the used Fat is a problem that should not be underestimated.
Der Erfindung liegt die Aufgabe zugrunde, die Kosten für einen solchen Drehturm zu minimieren und auch die Reserveteile-Haltung zu reduzieren.The invention has for its object to increase the cost of such a turret minimize and also reduce the stock of spare parts.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Drehantrieb mit seiner Wirkachse auf der senkrechten Mittelachse senkrecht nach unten oder nach oben gerichtet zur Rollendrehverbindung im Innern der Stützkonstruktion angeordnet ist und dass das Antriebselement das Drehmoment auf einen diametral und horizontal verlaufenden, unmittelbar oberhalb der Rollendrehverbindung angeordneten Mitnehmerarm überträgt, der zumindest einendig an den drehbaren Oberteil angeschlossen ist. Dadurch sind nur noch der Drehantrieb und ein Mitnehmerarm notwendig und die Kosten können entsprechend gesenkt werden. Eine Kalkulation der Kosten hat eine Senkung auf ca. 75% der bisherigen Kosten ergeben.The object is achieved according to the invention in that the rotary drive with its effective axis on the vertical central axis perpendicular downwards or arranged upwards to the roller slewing ring inside the support structure is and that the drive element the torque to a diametrical and horizontally extending, arranged directly above the roller slewing ring Carrier arm transmits, which is connected at least one end to the rotatable upper part is. As a result, only the rotary drive and a driving arm are necessary and the cost can be reduced accordingly. A calculation of the Cost has resulted in a reduction to approx. 75% of the previous costs.
Die sich ergebenden Auswirkungen auf die weitere Bauweise führt z.B. zu einfacheren Bauteilen, wobei der Drehantrieb über eine Kupplung an den diametral verlaufenden Mitnehmerarm angeschlossen ist.The resulting impact on the further construction leads e.g. to simpler Components, the rotary drive via a coupling to the diametrically extending Driver arm is connected.
Besondere Befestigungsmaßnahmen können sodann ebenfalls eingespart werden. Eine solche kann dadurch vereinfacht werden, dass der diametral verlaufende Mitnehmerarm an den Arm-Enden mit dem drehbaren Oberteil des Drehturms verbunden ist.Special fastening measures can then also be saved. Such can be simplified in that the diametrically extending driver arm connected at the arm ends to the rotating upper part of the turret is.
Ein zu übertragendes Drehmoment und die notwendige Steifigkeit bzw. das Widerstandsmoment werden dadurch erzielt, dass der Mitnehmerarm einen flachen, rechteckigen Querschnitt aufweist.A torque to be transmitted and the necessary rigidity or the section modulus are achieved in that the driver arm has a flat, rectangular Has cross-section.
Nach anderen Merkmalen kann der Mitnehmerarm auch als Mitnehmerdoppelarm ausgebildet sein. According to other features, the driver arm can also be used as a driver double arm be trained.
Die Anordnung des Drehantriebs ist nach weiteren Merkmalen dadurch geschützt möglich, dass der Drehantrieb an der Unterseite einer Bodenplatte der sockelartigen Stützkonstruktion befestigt ist.The arrangement of the rotary drive is protected according to other features possible that the rotary drive on the underside of a base plate of the base-like Support structure is attached.
Nach einer anderen Ausgestaltung ist vorgesehen, dass der Drehantrieb aus einem hydraulischen Schwenkantrieb besteht, dessen Wirkungsachse auf der senkrechten Mittelachse der Stützkonstruktion liegt.According to another embodiment, it is provided that the rotary drive consists of one hydraulic swivel drive exists, whose axis of action on the vertical Central axis of the support structure lies.
Dabei wird das hohe zu übertragende Drehmoment u.a. dadurch abgestützt, dass die Bodenplatte, der Innenring der Rollendrehverbindung und die sockelartige Stützkonstruktion eine feste Verbindung bilden.The high torque to be transmitted is supported by the fact that Base plate, the inner ring of the roller slewing ring and the base-like support structure form a firm connection.
Weitere Einsparungen an Kosten, Reserveteilen und Instandhaltung können dadurch erzielt werden, dass die Rollendrehverbindung am äußeren Umfang glatt, ohne Verzahnung , ausgeführt ist.This can result in further savings in costs, spare parts and maintenance can be achieved that the roller slewing ring on the outer circumference smooth, without teeth , is executed.
Die erfindungsgemäß Antriebsgestaltung erlaubt nach weiteren Maßnahmen, dass ausschließlich für die Rollendrehverbindung eine Fettschmiereinrichtung vorgesehen ist. Dementsprechend ist die Entsorgung an verbrauchtem Fett erheblich reduziert.After further measures, the drive design according to the invention allows that A grease lubrication device is provided only for the roller slewing ring is. Accordingly, the disposal of used fat is significantly reduced.
Entsprechend schwere Gießpfannen können nach einem Ausführungsbeispiel aufgenommen und gedreht werden, indem der hydraulische Schwenkantrieb bei einem maximalen Betriebsdruck von ca. 180 bar, einem spezifischen Drehmoment von 3.300 Nm / bar und einem effektiven Drehmoment von ca. 600.000 Nm betreibbar ist.Correspondingly heavy ladles can be added according to one embodiment and be turned by the hydraulic swivel drive at a maximum operating pressure of approx. 180 bar, a specific torque of 3,300 Nm / bar and an effective torque of approx. 600,000 Nm can be operated.

Verteilerrinnen eingesetzt und weist auf einem Fundament 2 eine sockelartige Stützkonstruktion
3 auf, auf der ein Oberteil 1a mit einem oder zwei oder mehreren
Schwenkarmen 4a, 4b drehbar ist. Die Schwenkarme 4a, 4b tragen Aufnahmemittel
5, z.B. Mulden für Gehängeschlaufen von Gießpfannen. Der Oberteil 1a ist mittels
einer Rollendrehverbindung 6, die aus einem Innenring 6a und einem Außenring 6b
gebildet ist, gelagert.The turret 1 is preferably used in continuous casting plants for ladles and / or
Used distribution channels and has a base-like support structure on a
Der Drehantrieb 7 liegt mit seiner Wirkachse 8 auf der senkrechten Mittelachse 9 und
im Höhenbereich der Rollendrehverbindung 6 im Inneren 3a der Stützkonstruktion 3.
Ein Antriebselement 10 des Drehantriebs 7 überträgt das Drehmoment auf einen
diametral und horizontal verlaufenden, unmittelbar auf Höhe der Rollendrehverbindung
6 angeordneten Mitnehmerarm 11. Ein Arm-Ende 11 b ist jeweils an den
drehbaren Oberteil 1a angeschlossen.The
Das Arm-Ende 11a ist mittels Schrauben mit einer zentrischen Kupplung 12 verbunden
und das Arm-Ende 11b ist mit dem Oberteil 1a verschweißt. In Fig. 2 ist außerdem
die Rollendrehverbindung 6 größer dargestellt. Jeweils ein oberer und ein unterer
Innenring 6a sind mittels einer Verbindungsschraube mit einem Verstärkungsflansch
14 einer Bodenplatte 13 zusammengeschraubt. Analog dazu ist der Außenring
6b mittels solcher Verbindungsschrauben mit dem Oberteil 1a verschraubt.The
Der Drehantrieb 7 überträgt das Drehmoment über die Kupplung 12 an den diametral
verlaufenden, mittig an die Kupplung 12 angeschlossenen Mitnehmerarm 11. Die
Verbindung kann z.B. durch Schweißen mit dem Oberteil 1a , wie gezeichnet, erfolgen.The
Für das Verschweißen ist ein flacher, rechteckiger Querschnitt 11c günstig, wie in
Fig. 3 ersichtlich ist.A flat,

Der Drehantrieb 7 besteht aus einem hydraulischen Schwenkantrieb 7a, dessen Wirkungsachse
8 auf der senkrechten Mittelachse 9 der Stützkonstruktion 3 liegt und
einen zylindrischen Abschnitt bildet, der mittels der Kupplung 12 an den Mitnehmerarm
11 zur Kraftübertragung angeschlossen ist (Fig. 3).The
Die Bodenplatte 13, der Innenring 6a der Rollendrehverbindung 6 und die sockelartige
Stützkonstruktion 3 bilden eine fest verbundene Einheit.The
Der in den Fig. 1 und 3 gezeigte Mitnehmerarm 11 kann gemäß Fig. 4 alternativ auch
als Mitnehmerdoppelarm 15 ausgeführt werden, wenn der erforderliche Schwenkweg
zur Verfügung steht. The
Eine weitere alternative Ausführungsform ergibt sich aus Fig. 5, in der der hydraulische
Schwenkantrieb 7a tiefer in das Innere des Oberteils 1a verlegt ist und vor allen
Dingen die Kupplung 12 nach unten weisend angeordnet ist. Der Ausbau des
Schwenkmotors für Reparaturen ist durch diese Anordnung begünstigt.Another alternative embodiment results from Fig. 5, in which the hydraulic

Da der Drehantrieb 7 unmittelbar auf den Mitnehmerarm 11 treibt, ist eine äußere
Verzahnung der Rollendrehverbindung 6 am äußeren Umfang nicht notwendig und
die Umfangsfläche ist daher glatt. Außerdem ist ausschließlich für die Rollendrehverbindung
6 eine Fettschmiereinrichtung (nicht gezeichnet) vorgesehen. Für vorgesehene
Gießpfannengewichte ist der hydraulische Schwenkantrieb 7a z.B. auf einen
maximalen Betriebsdruck von ca. 180 bar, ein spezifisches Drehmoment von 3.300
