In Figur 1 ist auf der linken Seite eine Walzhalle 1 in Walzrichtung und auf der rechten Seite eine Walzenwerkstatt 2 dargestellt. Beide Bereiche sind durch eine Wand 3 getrennt. In einem Walzgerüst 4 sind eine obere und eine untere Stützwalze 5, 6 sowie eine obere und eine untere Arbeitswalze 7, 8 angeordnet. Zum Transport aus dem Walzgerüst 4 in der Walzhalle 2 in die Walzenwerkstatt 2, um beispielsweise die Walzen nachzuschleifen, wird eine Lokomotive 9 verwendet. Diese befindet sich in einer Grube 10, die die Walzhalle 1 und die Walzenwerkstatt 2 verbindet. Sämtliche Vorrichtungen wie Schienen usw. sind auf einem Fundament bzw. mehreren Fundamenteni 1 aufgebaut. Die Lokomotive 9 kann somit aus einer Warteposition 12 am rechten Ende der Grube 10 zum Walzgerüst 4 hin bewegt werden. In der Figur 1 A ist im Querschnitt dargestellt, wie die Lokomotive 9 in der Grube 10 angeordnet ist. Wie ersichtlich, ist die Grube 10 in einen unteren schmalen Bereich 16 und einen oberen breiten Bereich 17 unterteilt. Der untere schmale Bereich 16 ist nur unwesentlich breiter wir die Lokomotive 9. Der obere breite Bereich 17 weist an seinen beiden Rän- dem 18, 19 Plattformen 20 auf. Diese sind beim Herausziehen bzw. Transport eines Arbeitswalzensatzes 7, 8 heruntergeklappt und weisen an ihrer Oberseite Führungsschienen 21 auf, auf denen der Arbeitswalzensatz 7, 8 bewegt werden kann. Die Plattformen 20 weisen einen Abstand auf, der eine an der Lokomotive 9 an der Oberseite 13 angebrachte Kuppelvorrichtung 14 ein durchfahren er- möglicht. Zum Transportieren des im Durchmesser größeren Stützwalzensatzes 5, 6 werden die Plattformen 20 hochgeklappt und somit die Durchfahrt verbreitert. In Figur 1 ist eine Ausbildung dargestellt, bei der die Arbeitswalzen 7, 8 direkt in die Walzenwerkstatt 2 gezogen werden. Die Plattformen 20 sind nach unten geklappt, um ein Überfahren zu ermöglichen. In der Walzenwerkstatt 2 befindet sich eine Stützkonstruktion 26, die das Handhaben / den Transport bei der Bearbeitung der einzelnen Arbeitswalzen vereinfacht. Wie ersichtlich, werden dazu die Arbeitswalzen 7, 8 in die Stützkonstruktion 26 verfahren.In Figure 1, a rolling hall 1 in the rolling direction and on the right side of a rolling mill 2 is shown on the left side. Both areas are separated by a wall 3. In a rolling mill 4, an upper and a lower support roller 5, 6 and an upper and a lower work roll 7, 8 are arranged. For transport from the roll stand 4 in the rolling hall 2 in the roll workshop 2, for example, to re-sharpen the rolls, a locomotive 9 is used. This is located in a pit 10, which connects the rolling hall 1 and the roller workshop 2. All devices such as rails, etc. are built on a foundation or several foundationsi 1. The locomotive 9 can thus be moved from a waiting position 12 at the right end of the pit 10 to the rolling stand 4 out. In the figure 1 A is shown in cross section, as the locomotive 9 is arranged in the pit 10. As can be seen, the pit 10 is divided into a lower narrow area 16 and an upper wide area 17. The lower narrow region 16 is only slightly wider than the locomotive 9. The upper broad region 17 has platforms 20 at its two edges 18, 19. These are folded down when pulling or transporting a set of work rolls 7, 8 and have at their top guide rails 21 on which the set of work rolls 7, 8 can be moved. The platforms 20 have a spacing which allows a coupling device 14 attached to the locomotive 9 on the upper side 13 to pass through. For transporting the larger diameter support roll set 5, 6, the platforms 20 are folded up, thus widening the passage. FIG. 1 shows an embodiment in which the work rolls 7, 8 are drawn directly into the roll workshop 2. The platforms 20 are folded down to allow a run over. In the roller workshop 2 is a support structure 26, the handling / transport at the processing of individual work rolls simplified. As can be seen, the work rolls 7, 8 are moved into the support structure 26 for this purpose.
Die Stützkonstruktion 26 ist in Figur 2 genauer dargestellt. Die Stützkonstruktion 26 besteht aus einem linken Teil 27 und einem rechten Teil 28, die jeweils rechts und links von der Walzenwechselgrube 10 aufgebaut sind. Der Bereich oberhalb der Walzenwechselgrube 10 ist frei. Dies ermöglicht ein Durchfahren eines Stützwalzensatzes. An der Oberseite 29 sind Schienen 30 angeordnet, auf denen ein Wechselwagen 31 aufliegt. Der Wechselwagen 31 weist an seiner Unterseite Vorrichtungen 32 zur Aufnahme der Arbeitswalzen 7, 8 auf. Da sowohl ein gebrauchter als auch ein neuer Arbeitswalzensatz gleichzeitig in der Stützkonstruktion 26 vorhanden sind, sind mindestens zwei Vorrichtungen 32 zur Aufnahme vorgesehen. Der Wechselwagen 31 mit den Vorrichtungen 32 wird mittels eines Hydraulikzylinders 33 und einer Schubstange 34 seitlich verfahren. Dabei ist die Schubstange 34 in einer ersten Ausführung mit der rechten Seite der Vorrichtung 32 zur Aufnahme der Arbeitswalzen 7, 8 verbunden.The support structure 26 is shown in more detail in FIG. The support structure 26 consists of a left part 27 and a right part 28, which are each constructed to the right and left of the roll change pit 10. The area above the roll change pit 10 is free. This allows driving through a support roller set. At the top 29 rails 30 are arranged, on which a change carriage 31 rests. The change carriage 31 has on its underside devices 32 for receiving the work rolls 7, 8. Since both a used and a new set of work rolls are present simultaneously in the support structure 26, at least two devices 32 are provided for receiving. The change carriage 31 with the devices 32 is moved laterally by means of a hydraulic cylinder 33 and a push rod 34. In this case, the push rod 34 is connected in a first embodiment with the right side of the device 32 for receiving the work rolls 7, 8.
In einer ersten Position wird, wie in Figur 3 dargestellt, ein gebrauchter Arbeitswalzensatz 7,8 in die linke Vorrichtung 32 aufgenommen und angehoben, d.h. von der Lokomotive 9 angekuppelt. Dabei liegt der Wechselwagen 31 auf dem linken Teil 27 und dem rechten Teil 28 der Stützkonstruktion 26 auf.In a first position, as shown in FIG. 3, a used work roll set 7, 8 is received in the left hand device 32 and raised, i. from the locomotive 9 coupled. In this case, the change carriage 31 rests on the left part 27 and the right part 28 of the support structure 26.
Anschließend wird ein überarbeiteter / neuer Arbeitswalzensatz 35, wie in Figur 4 zu sehen, der sich bereits in der rechten Vorrichtung 32 befindet, nach links verschoben und gelangt so in Linie mit der Lokomotive 9, wird anschließend auf die Plattformen 20 mit den Schienen abgesenkt und in das Walzgerüst 4 (nicht dargestellt) geschoben. Die Stützkonstruktion 26 mit dem Wechselwagen 31 und den daran befindlichen Vorrichtungen 32 zur Aufnahme der Arbeitswalzen ermöglicht es, auf einen Hallenkran zu verzichten.Subsequently, a revised / new set of work rolls 35, as seen in Figure 4, which is already in the right-hand device 32, moved to the left and so gets in line with the locomotive 9, is then lowered onto the platforms 20 with the rails and pushed into the rolling stand 4 (not shown). The support structure 26 with the change carriage 31 and the devices 32 thereon for receiving the work rolls makes it possible to dispense with a hall crane.
Dieser wird wiederum bei der Handhabung der Stützwalzen, wie in Figur 5 zu sehen, benötigt. Um die Stützwalzen in die Walzenwerkstatt 2 zu verbringen, wird der Wechselwagen 31 mit den Vorrichtungen 32 derart nach recht verfahren, dass eine Lücke 33 zwischen dem linken Teil 27 und dem rechten Teil 28 der Stützkonstruktion 26 entsteht. In diese Lücke 33 kann der Stützwalzensatz mittels der Lokomotive 9 gezogen werden. Durch eine spezielle Ausgestaltung des Wechselwagens 31 mit mehreren Rollen 36 und einer entsprechenden Länge kann die Lücke zwischen dem linken Teil 27 und dem rechten Teil 28 der Stützkonstruktion 26 freigegeben werden. Der Wechselwagen 31 wird auf der Oberseite 29 der Stützkonstruktion 26 auf Schienen 30 verfahren. An dem Wechselwagen 31 sind an der Unterseite Vorrichtungen 32 angebracht, deren Gestaltung ein einfahren und aufliegen der Arbeitswalzen 7, 8, 22 erlaubt. Die Vorrichtungen 32 sind beispielsweise als Stahlkonstruktionen ausgebildet.This in turn is required in the handling of the support rollers, as shown in FIG. To spend the back-up rolls in the roll workshop 2, the change carriage 31 is moved with the devices 32 so right that a gap 33 between the left part 27 and the right part 28 of the support structure 26 is formed. In this gap 33, the support roller set can be pulled by the locomotive 9. By a special embodiment of the swap body 31 with a plurality of rollers 36 and a corresponding length, the gap between the left part 27 and the right part 28 of the support structure 26 can be released. The change carriage 31 is moved on the top 29 of the support structure 26 on rails 30. On the change carriage 31 devices 32 are mounted on the bottom, the design of a retract and rest of the work rolls 7, 8, 22 allowed. The devices 32 are designed, for example, as steel structures.
In Figur 6 ist eine Ausbildung dargestellt, bei der die Stützwalzen 5, 6 direkt in die Walzenwerkstatt 2 gezogen werden. Die Plattformen 20 in der Walzhalle 1 und in der Walzenwerkstatt 2 sind nach oben geklappt, um ein Durchfahren zu ermöglichen. In der Walzenwerkstatt 2 befindet sich eine Stützkonstruktion 26, die das Handling bei der Bearbeitung der einzelnen Arbeitswalzen vereinfacht. Die Stützkonstruktion 26 dient ausschließlich der Handhabung der Arbeitswalzen. Die Stützwalzen 5, 6 ragen über die Oberkante des Wechselwagens 31 hinaus. In dieser Figur ist einmal dargestellt, wie die Lokomotive 9 in der WaIz- halle 1 an die untere Stützwalze 5 gekoppelt wird. Eine andere Position ist auf der rechten Seite, in der Walzenwerkstatt 2 zu sehen. Hier befindet sich die gleiche Lokomotive 9, in der Walzenwechselgrube 10 ist nur eine einzige Lokomotive 9 vorgesehen, in ihrer Park- / oder Warteposition und wurde gerade von den Stützwalzen 5, 6 abgekoppelt. Der in der Walzhalle 1 eingezeichnete Schnitt ist oben rechts dargestellt, wobei die Plattformen 20 hochgeklappt sind, um das Durchfahren der Stützwalzen 5, 6 durch die Walzenwechselgrube 10 in die Walzenwerkstatt 2 zu ermöglichen. BezugszeichenlisteFIG. 6 shows an embodiment in which the support rollers 5, 6 are pulled directly into the roller workshop 2. The platforms 20 in the rolling hall 1 and in the roller workshop 2 are folded up to allow passage. In the roller workshop 2 is a support structure 26, which simplifies the handling of the processing of the individual work rolls. The support structure 26 is used exclusively for handling the work rolls. The support rollers 5, 6 protrude beyond the upper edge of the changing carriage 31. In this figure, it is shown once how the locomotive 9 in WaIz- hall 1 is coupled to the lower support roller 5. Another position can be seen on the right side, in the roller workshop 2. Here is the same locomotive 9, in the roll change pit 10, only a single locomotive 9 is provided in their parking / or waiting position and was just decoupled from the support rollers 5, 6. The drawn in the rolling hall 1 section is shown at the top right, the platforms 20 are folded up to allow the passage of the support rollers 5, 6 through the roll change pit 10 in the roll workshop 2.
