Description

Vorrichtung zum Handhaben und/oder Transportieren von Walzen eines Walzgerüsts  Device for handling and / or transporting rolls of a roll stand
Die Erfindung betrifft eine Vorrichtung zum Handhaben und/oder Transportieren von Arbeitswalzen und/oder Stützwalzen eines Walzgerüsts, mit der die Arbeitswalzen und/oder die Stützwalzen mittels einer auf einer Fahrbahn verfahrbaren Lokomotive von dem Walzgerüst in eine Walzenwerkstatt verbracht werden können. The invention relates to a device for handling and / or transporting work rolls and / or back-up rolls of a roll stand, with which the work rolls and / or the back-up rolls can be moved from the rolling stand to a roll workshop by means of a locomotive movable on a road surface.
Vorrichtungen dieser Art dienen dazu, einen Wechsel der Walzen eines Walzgerüsts zu ermöglichen, wenn die Walzen ihre Einsatzdauer erreicht haben und zur Nacharbeitung in eine Walzenwerkstatt verbracht werden müssen. Die entnommenen Walzen werden dann durch einen neuen Walzensatz ersetzt, so dass die Produktion fortgesetzt werden kann. Devices of this type are used to allow a change of the rolls of a rolling mill, when the rollers have reached their service life and must be spent for reworking in a roller workshop. The removed rolls are then replaced with a new set of rolls so that production can continue.
Im Stand der Technik sind vielfältige Lösungen zur Ausgestaltung einer gattungsgemäßen Vorrichtung bekannt. Die EP 1 954 416 B1 zeigt eine solche Vorrichtung, bei der vorgesehen ist, dass eine Stützkonstruktion zur Aufnahme der Walzen einen Wechselwagen aufweist, wobei die Stützkonstruktion an ihrer Oberseite Schienen hat, auf denen der Wechselwagen aufliegt und quer zu einer Walzenwechselgrube verfahrbar ist, wobei der Wechselwagen mit Vorrichtungen zur Aufnahme der Walzensätze ausgebildet ist. Ähnliche Lösungen werden in der EP 1 951 452 B1 , in der WO 2005/089972 A1 , in der WO 2007/080091 A1 , in der EP 1 951 453 B1 , in der WO 03/015949 A1 und in der DE 31 23 933 C2 beschrieben. In the prior art various solutions for the design of a generic device are known. The EP 1 954 416 B1 shows such a device, in which it is provided that a support structure for receiving the rollers has a change carriage, wherein the support structure on its upper side rails, on which the change carriage rests and is movable transversely to a roll change pit, wherein the change carriage is formed with devices for receiving the roller sets. Similar solutions are described in EP 1 951 452 B1, in WO 2005/089972 A1, in WO 2007/080091 A1, in EP 1 951 453 B1, in WO 03/015949 A1 and in DE 31 23 933 C2 described.
Die DE 15 27 628 A1 offenbart eine Walzenwechselvorrichtung, die sich da- durch auszeichnet, dass ein Walzentraggerüst zwei übereinander angeordneteDE 15 27 628 A1 discloses a roll changing device, which is characterized in that a roll tentering stand has two superimposed one another
Plattformen hat, die jeweils ein Paar Arbeitswalzen aufnehmen können, wobei dieses Gerüst vertikal verschiebbar ist, so dass jede der beiden Plattformen zur Überführung der Arbeitswalzen zwischen der Plattform und dem Walzwerk und zwischen der Plattform und einem Walzenlagerplatz in entsprechender Höhe angeordnet werden kann. Hiermit kann also ein Wechselsatz Walzen nahe dem Walzgerüst vorgehalten werden, bis er eingewechselt wird. Nachteilig ist hier die relativ aufwändige Bauweise der Vorrichtung. Has platforms that can each accommodate a pair of work rolls, wherein this framework is vertically displaceable, so that each of the two platforms for transferring the work rolls between the platform and the rolling mill and between the platform and a roller storage space can be arranged at a corresponding height. Hereby, therefore, a replacement set of rollers can be kept near the rolling mill until he is switched. The disadvantage here is the relatively complex construction of the device.
In der WO 2007/080087 A1 wird der bauliche Aufwand der gattungsgemäßen Wechselvorrichtungen erkannt. Um diesen Aufwand zu reduzieren, wird hier vorgeschlagen, einen ersten Walzensatz eines Walzgerüsts mit einer ersten Lokomotive und einen zweiten Walzensatz in demselben Walzgerüst mit einer zweiten Lokomotive zu wechseln, wobei als erste Lokomotive und als zweite Lokomotive dieselbe Lokomotive verwendet wird. Die Lokomotive verfährt dabei auf einer Fahrbahn. Dies erfordert in nachteiliger Weise einen relativ hohen konstruktiven Aufwand zum Ankoppeln der jeweiligen Walzen an der einen Lo- komotive. In WO 2007/080087 A1, the structural complexity of the generic changing devices is recognized. To reduce this effort, it is proposed here to change a first set of rolls of a rolling mill with a first locomotive and a second set of rolls in the same rolling mill with a second locomotive, being used as a first locomotive and as the second locomotive same locomotive. The locomotive moves thereby on a roadway. This disadvantageously requires a relatively high design complexity for coupling the respective rollers to the one locomotive.
Der vorliegenden Erfindung liegt die A u f g a b e zugrunde, eine gattungsgemäße Vorrichtung dahingehend weiter zu verbessern, dass eine einfachere Konstruktion vorliegt und Bauteile nur geringer Komplexität benötigt werden. The present invention is based on the invention to further improve a generic device to the effect that a simpler design is present and components of only low complexity are needed.
Die L ö s u n g dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass zumindest zwei auf unterschiedlichen Höhenniveaus angeordnete Fahrbahnen angeordnet sind, auf denen eine Walze mittels der Lokomotive verfahren werden kann, und dass ein Hubtisch vorhanden ist, der bestimmt und geeignet ist, die Lokomotive auf eines der mindestens zwei unterschiedlichen Höhenniveaus anzuheben oder abzusenken, um sie auf die jeweilige Fahrbahn zu verbringen. The solution to this problem by the invention is characterized in that at least two lanes arranged at different height levels are arranged, on which a roller can be moved by means of the locomotive, and that a lifting table is provided, which is intended and suitable, the locomotive to raise or lower on one of the at least two different height levels to spend on the respective roadway.
Ein Höhenniveau der Fahrbahn ist bevorzugt so angeordnet, dass mindestens eine Arbeitswalze aus dem Walzgerüst verfahren werden kann. Ein weiteres Höhenniveau der Fahrbahn ist bevorzugt so angeordnet, dass mindestens eine Stützwalze aus dem Walzgerüst verfahren werden kann. A height level of the roadway is preferably arranged so that at least one work roll can be moved out of the rolling mill stand. Another one Height level of the roadway is preferably arranged so that at least one support roller can be moved out of the rolling stand.
Der Hubtisch kann am Ende der Fahrbahnen angeordnet sein. Er kann alternativ aber auch im Bereich der Fahrbahnen angeordnet sein. The lift table can be arranged at the end of the lanes. Alternatively, however, it may also be arranged in the area of the roadways.
Mindestens eine der Fahrbahnen kann an einen Querverschiebetisch angrenzen oder diesen kreuzen. Hinsichtlich der Positionierung des Querverschiebeti- sches sind grundsätzlich zwei verschiedene Anordnungen möglich: Der Querverschiebetisch kann zwischen dem Hubtisch und dem Walzgerüst angeordnet sein. Es ist aber auch möglich, dass der Hubtisch zwischen dem Walzgerüst und dem Querverschiebetisch angeordnet ist. At least one of the lanes may adjoin or intersect a transverse shift table. With regard to the positioning of the transverse sliding table, basically two different arrangements are possible: The transverse sliding table can be arranged between the lifting table and the rolling stand. But it is also possible that the lifting table is arranged between the rolling stand and the transverse displacement table.
Jede der Fahrbahnen kann mit Schienen versehen sein, auf der die Lokomotive verfahrbar ist. Each of the lanes may be provided with rails on which the locomotive is movable.
Die zu transportierenden Walzen bzw. Walzensätze gleiten direkt auf den Verfahrschienen. The rolls or sets of rolls to be transported slide directly onto the travel rails.
Zur Aufnahme der Walzen kann ein Walzenwechselstuhl angeordnet sein. To accommodate the rollers, a roll changing chair can be arranged.
Die Länge des Hubtisches ist - in Fahrtrichtung der Lokomotive gesehen - vorzugsweise gleich lang oder nur geringfügig länger als die Länge der Lokomotive. Dies ermöglicht eine kurze Bauweise. Der Hubtisch kann mit Hebe- und Absenkmitteln auf eine gewünschte Höhe angehoben und abgesenkt werden, so dass die Lokomotive problemlos vom Hubtisch auf die Fahrbahn und zurück fahren kann. Der Hubtisch kann dabei mit mindestens einem hydraulischen Kolben-Zylinder-System angehoben und abgesenkt werden. Mit der vorgeschlagenen Lösung wird es möglich, mit nur einer einzigen Lokomotive für den Wechsel aller Walzen des Walzgerüsts auszukommen und dennoch ein komfortables Handling der Walzen während ihrer Handhabung bzw. ihres Transports zu erzielen. Ein spezieller Koppelmechanismus ist nicht erforderlich, um mit nur einer Lokomotive die verschiedenen Walzen zu handhaben. The length of the lifting table is - seen in the direction of travel of the locomotive - preferably the same length or only slightly longer than the length of the locomotive. This allows a short construction. The lift table can be raised and lowered to a desired height with lifting and lowering means so that the locomotive can easily travel from the lift table to the roadway and back. The lift table can be raised and lowered with at least one hydraulic piston-cylinder system. With the proposed solution, it is possible to make do with only a single locomotive for the change of all rolls of the rolling mill and yet to achieve a comfortable handling of the rolls during their handling or their transport. A special coupling mechanism is not required to handle the different rollers with only one locomotive.
Der Erfindungsvorschlag kommt bevorzugt bei Quarto-Gerüsten zum Einsatz, ist hierauf aber nicht beschränkt. The proposed invention is preferably used in quarto frameworks, but is not limited thereto.

Betreffend den Wechsel der Stützwalzen 4, 5 sei auf den in Fig. 3 skizzierten Walzenwechselstuhl 13 hingewiesen, der zur Handhabung der Stützwalzen 4, 5 eingesetzt wird. Details zu einem solchen Walzenwechselstuhl sind in der EP 1 951 452 B1 der Anmelderin beschrieben, auf die insoweit Bezug genommen wird. Wesentlich ist, dass nur eine einzige Lokomotive 9 eingesetzt wird, um für das Wechseln aller Walzen 2, 3, 4, 5 die benötigten Verfahrbewegungen auszuführen. Hierzu ist erfindungsgemäß vorgesehen, dass ein Hubtisch 11 vorhanden ist. Dieser ist so ausgelegt, dass er die Lokomotive 9 auf eines der beiden Höhenniveaus hi bzw. h2 anheben bzw. absenken kann, um so die Lokomotive 9 auf die jeweilige Fahrbahn 7 bzw. 8 zu verbringen. Die Hubbewegung des Hubtisches 11 ist in Fig. 1 mit dem Doppelpfeil 16 markiert. Zur Sicherung des Hubtisches sind Verriegelungen 18 im unteren Schachtbereich vorgesehen. The first height level hi of the roadway 7 is chosen such that it is suitable for pulling a work roll 2 or both work rolls 2, 3 out of the weighing stand 6 or for pushing these rolls into the rolling stand 6. The second height level h 2 of the lane 8 is lower and is aligned to pull a support roller 4 out of the rolling stand 6 or to push it into the rolling stand 6. With regard to the change of the support rollers 4, 5, reference is made to the roll changing chair 13 sketched in FIG. 3, which is used for handling the support rollers 4, 5. Details of such a roll changing chair are described in EP 1 951 452 B1 of the Applicant, to which reference is made in this respect. It is essential that only a single locomotive 9 is used to perform the required traversing movements for changing all the rollers 2, 3, 4, 5. For this purpose, the invention provides that a lifting table 11 is present. This is designed so that it can lift or lower the locomotive 9 to one of the two height levels hi and h 2 , so as to spend the locomotive 9 on the respective lane 7 and 8 respectively. The lifting movement of the lifting table 11 is marked in Fig. 1 with the double arrow 16. To secure the lifting table locks 18 are provided in the lower shaft area.
Wie insbesondere aus Fig. 2 hervorgeht, ist auch ein Querverschiebetisch 12 vorgesehen. Mit diesem kann eine Querverschiebung erfolgen, und zwar in Richtung des Doppelpfeils 17 in Fig. 2. Zur Technologie der Querverschiebung finden sich in der EP 1 951 453 B1 der Anmelderin detaillierte Hinweise, so dass auf dieses Dokument entsprechend Bezug genommen wird. Mit der vorgeschlagenen Lösung wird erreicht, dass eine einzige Lokomotive 9 zum Einsatz kommen kann, um alle Walzen 2, 3, 4, 5 des Walzgerüsts 6 zu handhaben bzw. zu transportieren. Dennoch kann die Lokomotive 9 stets optimal und ohne besondere Koppelvorrichtungen eingesetzt werden, so dass ihr Einsatz konstruktiv einfach wird. As can be seen in particular from FIG. 2, a transverse displacement table 12 is also provided. With this, a transverse displacement can take place, in the direction of the double arrow 17 in Fig. 2. For the technology of the transverse displacement can be found in EP 1 951 453 B1 of the applicant detailed information, so that reference is made to this document. With the proposed solution is achieved that a single locomotive 9 can be used to handle all rolls 2, 3, 4, 5 of the roll stand 6 or to transport. Nevertheless, the locomotive 9 can always be used optimally and without special coupling devices, so that their use is structurally simple.
In den Figuren 4 bis 8 sind insgesamt drei verschiedene konkrete Ausführungsbeispiele der Erfindung dargestellt. Alle drei Ausführungsbeispiele arbeiten prinzipiell gemäß dem Erfindungskonzept, d. h. es sind (zumindest) zwei auf unterschiedlichen Höhenniveaus h-i, h2 angeordnete Fahrbahnen 7, 8 vorhan- den, auf denen eine Walze 2, 3, 4, 5 mittels der Lokomotive 9 verfahren werden kann, wobei ferner ein Hubtisch 11 vorhanden ist, der bestimmt und geeignet ist, die Lokomotive 9 auf eines der mindestens zwei unterschiedlichen Höhenniveaus h-i, h2 anzuheben oder abzusenken, um sie auf die jeweilige Fahrbahn 7, 8 zu verbringen. Bei dem ersten konkreten Ausführungsbeispiel gemäß den Figuren 4 und 5 ist der Querverschiebetisch 12 im Bereich der Fahrbahnen 7, 8 angeordnet, d. h. der Querverschiebetisch kreuzt die Fahrbahnen 7, 8. Der Hubtisch 11 sitzt am Ende der Fahrbahnen 7, 8. Die Lokomotive 9 ist relativ leistungsstark ausgeführt. Wie in Fig. 5b gesehen werden kann, wird ein Paar Arbeitswalzen 2, 3 direkt auf den Verfahrschienen verfahren. Wie in Fig. 5c gesehen werden kann, ist die Lokomotive 9 in der Lage, auch die beiden Stützwalzen 4, 5 auf einem Walzenwechselstuhl 13 zu verfahren (in Fig. 5c ist die obere Fahrbahn 7 nicht dargestellt). Das zweite konkrete Ausführungsbeispiel gemäß den Figuren 6a bis 6d ist ähnlich ausgeführt wie das erste Ausführungsbeispiel (Fig. 4 und 5). Namentlich ist der Querschiebetisch 12 im Bereich der Fahrbahnen 7, 8 angeordnet; die Draufsicht auf das zweite Ausführungsbeispiel entspricht derjenigen auf das erste Ausführungsbeispiel (s. Fig. 4). Die Lokomotive 9 ist hier lediglich schwä- eher ausgeführt. Demgemäß ist es zwar noch möglich, die beiden Arbeitswalzen 2, 3 als Paar zu verfahren (s. Fig. 6b). Allerdings müssen die Stützwalzen 4, 5 separat von der Lokomotive 9 verfahren werden, wie es in den Figuren 6c und 6d gezeigt ist. Das dritte konkrete Ausführungsbeispiel gemäß den Figuren 7 und 8 lehnt sich an das zweite Ausführungsbeispiel an, d. h. es kommt eine relativ schwache Lokomotive 9 zum Einsatz. Demgemäß werden auch hier die Stützwalzen 4, 5 separat verfahren (s. Fig. 8c und 8d). Der Unterschied zu den vorherigen Ausführungsbeispielen liegt darin, dass der Hubtisch 11 nicht mehr am Fahrbah- nende angeordnet ist, sondern im Bereich der Fahrbahnen 7, 8. D. h. die Fahrbahnen 7, 8 setzen sich jenseits des Hubtisches 11 in den vom Walzgerüst 6 entfernten Bereich fort. In the figures 4 to 8 a total of three different concrete embodiments of the invention are shown. All three embodiments work in principle according to the concept of the invention, ie there are (at least) two roadways 7, 8 arranged at different height levels hi, h 2 , on which a roller 2, 3, 4, 5 can be moved by means of the locomotive 9 Furthermore, there is a lifting table 11, which is intended and suitable for raising or lowering the locomotive 9 to one of the at least two different height levels hi, h 2 in order to transfer it to the respective lane 7, 8. In the first concrete exemplary embodiment according to FIGS. 4 and 5, the transverse displacement table 12 is arranged in the region of the roadways 7, 8, ie the transverse displacement table crosses the roadways 7, 8. The lifting table 11 sits at the end of the roadways 7, 8. The locomotive 9 is relatively powerful. As can be seen in Fig. 5b, a pair of work rolls 2, 3 are moved directly on the travel rails. As can be seen in Fig. 5c, the locomotive 9 is able to move the two support rollers 4, 5 on a roll changing chair 13 (in Fig. 5c, the upper lane 7 is not shown). The second concrete embodiment according to FIGS. 6a to 6d is designed similarly to the first exemplary embodiment (FIGS. 4 and 5). In particular, the transverse sliding table 12 is arranged in the region of the roadways 7, 8; the plan view of the second embodiment corresponds to that of the first embodiment (see Fig. 4). The locomotive 9 is here only schwä- rather executed. Accordingly, it is still possible to move the two work rolls 2, 3 as a pair (see Fig. 6b). However, the back-up rolls 4, 5 must be moved separately from the locomotive 9, as shown in Figures 6c and 6d. The third concrete embodiment according to FIGS. 7 and 8 is based on the second exemplary embodiment, that is to say a relatively weak locomotive 9 is used. Accordingly, the support rollers 4, 5 are also moved separately here (see Fig. 8c and 8d). The difference from the previous exemplary embodiments lies in the fact that the lifting table 11 is no longer arranged at the end of the travel, but in the area of the carriageways 7, 8. the lanes 7, 8 continue beyond the lifting table 11 in the area remote from the rolling mill 6 area.
Während grundsätzlich der Querverschiebetisch 12 auch hier zwischen dem Hubtisch 11 und dem Walzgerüst 6 angeordnet sein könnte, ist im Ausfüh- rungsbeispiel nach Fig. 7 und 8 vorgesehen, dass der Querverschiebetisch 12 jenseits des Hubtisches 11 im vom Walzgerüst 6 entfernten Bereich der Fahr- bahnen 7, 8 vorgesehen ist. Der Querverschiebetisch 12 ist im Übrigen hier kleiner ausgeführt als in den Fällen der Figuren 4 bis 6. While in principle the transverse displacement table 12 could also be arranged here between the lifting table 11 and the rolling stand 6, in the exemplary embodiment according to FIGS. 7 and 8 it is provided that the transverse displacement table 12 beyond the lifting table 11 is located in the region of the driving distance from the rolling stand 6. tracks 7, 8 is provided. Incidentally, the transverse displacement table 12 is made smaller here than in the cases of FIGS. 4 to 6.
Typische Verfahrgeschwindigkeiten der von der Lokomotive 9 gezogenen Wechselwagen liegen bei der Beladung mit den Arbeitswalzen bei ca. 200 bis 400 mm/s und bei der Beladung mit einer einzelnen Stützwalze in derselben Größenordnung. Bei der Beladung mit zwei Stützwalzen ist ein Wert zwischen 50 und 100 mm/s typisch. Typical travel speeds of the change cars pulled by the locomotive 9 are approximately 200 to 400 mm / s when loaded with the work rolls and of the same order of magnitude when loaded with a single back-up roll. When loading with two back-up rolls, a value between 50 and 100 mm / s is typical.
