Description

Die Erfindung betrifft eine Einrichtung an einem Stütz-und Führungsgerüst für eine Stranggießanlage, insbesondere für eine Stahlbrammen-Stranggießanlage,, mit den Strang an zwei gegenüberliegenden Seiten stützenden Rollenbahnen, wobei eine der beiden Rollenbahnen an einem ersten Tragwerk und die andere Rollenbahn an einem zweiten Tragwerk angeordnet sind, welches gegen das erste Tragwerk mittels Zuganker spann- und mit dem ersten Tragwerk verbindbar bzw. von dem ersten Tragwerk lösbar ist.The invention relates to a device on a support and guide frame for a continuous casting installation, in particular for a steel slab continuous casting installation, with the strand supporting roller tracks on two opposite sides, one of the two roller tracks on a first supporting structure and the other roller conveyor on a second supporting structure are arranged, which can be tensioned against the first structure by means of tie rods and connected to the first structure or detachable from the first structure.

Es ist bekannt (AT-PS 343 303), die zur Verbindung der beiden Tragwerke dienenden Zuganker an den Tragwerken mittels Keilen bzw. Einlegestücken zu fixieren. Ein solcher Keil bzw. ein solches Einlegestück weist eine Masse von mehr als 50 kg auf und ist daher nur schwer handzuhaben. Einlegestücke müssen mit jeweils einem Sicherungsbolzen gesichert werden, der Bohrungen des Tragwerkes und eine Bohrung des Einlegestückes durchsetzt. Infolge des hohen Gewichtes des Einlegestückes ist es schwierig, diese Bohrungen genau fluchtend zueinander auszurichten, sodaß die Anbringung des Sicherungsbolzens die Montage des Stütz-und Führungsgerüstes weiter erschwert.It is known (AT-PS 343 303) to fix the tie rods used to connect the two structures to the structures by means of wedges or inserts. Such a wedge or insert has a mass of more than 50 kg and is therefore difficult to handle. Inlays must be secured with a safety bolt each, which penetrates holes in the supporting structure and a hole in the insert. As a result of the high weight of the insert, it is difficult to align these bores exactly in line with one another, so that the attachment of the securing bolt further complicates the assembly of the support and guide frame.

Die Erfindung bezweckt die Vermeidung dieser Schwierigkeiten und stellt sich die Aufgabe, eine Einrichtung an einem Stütz- und Führungsgerüst der eingangs beschriebenen Art zu schaffen, welche ein leichtes Verbinden und Lösen der Zuganker mit bzw. von dem Tragwerk ermöglicht, wobei zur Herstellung bzw. zum Lösen der Verbindung nur leicht handzuhabende Teile manipuliert werden müssen.The invention aims to avoid these difficulties and has as its object a device rt a support and guide structure of the input A described in the introduction which enables an easy connection and disconnection of the tie rods to and from the support structure, said to-handle parts have to be manipulated only slightly for the production and for releasing the connection.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Verbindung zwischen Tragwerk und Zuganker jeweils eine Renkverbindung vorgesehen ist, bei der eine mindestens eine Ausnehmung aufweisende Scheibe am Tragwerk angeordnet ist, in die ein einen dieser Ausnehmung entsprechenden seitlichen Ansatz aufweisender Zugankerkopf einsetzbar ist und der Zugankerkopf oder die Scheibe in eine den Zuganker axial fixierende Befestigungsposition verdrehbar ist.This object is achieved in that a bayonet connection is provided as the connection between the supporting structure and the tie rod, in which a disc having at least one recess is arranged on the supporting structure, into which a tie rod head having a lateral extension corresponding to this recess can be inserted and the tie rod head or the disc can be rotated into a fastening position axially fixing the tie rod.

Gemäß einer bevorzugten Ausführungsform sind die Scheiben verdrehbar und jeweils in einen nach außen mit einer Abdeckplatte verschließbaren Hohlraum des Tragwerkes eingesetzt.According to a preferred embodiment, the disks can be rotated and are each inserted into a cavity of the supporting structure that can be closed to the outside with a cover plate.

Vorteilhaft sind dabei am Umfang der Scheiben Bohrungen vorgesehen, in die ein Betätigungshebel oder ein an der Abdeckplatte angeordneter Sperrstift einsetzbar sind.In this case, holes are advantageously provided on the circumference of the disks, into which an actuating lever or a locking pin arranged on the cover plate can be inserted.

Zweckmäßig sind die Scheiben der Renkverbindungen an dem ersten Tragwerk eines Stütz- und Führungsgerüstes vorgesehen, bei welchem Stelltriebe zur Verstellung des zweiten Tragwerkes gegenüber dem ersten Tragwerk einerseits mit dem zweiten Tragwerk und anderseits mit den Zugankern verbunden sind, derart, daß die Zuganker an dem ersten Tragwerk lösbar befestigt sind und nach Lösen der Verbindungsmittel aus der die Tragwerke verbindenden Position mittels der Stelltriebe aus dem ersten Tragwerk entfernbar und in eine Rückzugsposition in das zweite Tragwerk einziehbar sind. Bei dieser Ausführungsform ist eine Trennung des ersten Tragwerkes vom zweiten in besonders einfacher und schneller Weise möglich.The washers of the bayonet connections are expediently provided on the first supporting structure of a supporting and guiding frame, in which actuators for adjusting the second supporting structure are connected on the one hand to the second supporting structure and on the other hand to the tie rods in such a way that the tie rods on the first Support structure are releasably attached and after releasing the connecting means from the position connecting the supporting structures can be removed from the first supporting structure by means of the actuators and retracted into a retracted position in the second supporting structure. In this embodiment, a separation of the first structure from the second one is special simple and quick way possible.

Die Erfindung ist nachfolgend anhand der Zeichnung näher erläutert, wobei Fig. 1 eine Ansicht eines Stütz- und Führungsgerüstes in Richtung der Stranglängsachse teilweise im Schnitt und Fig. '2 einen in verkleinertem Maßstab dargestellten Schnitt gemäß der Linie II-II der Fig. 1 zeigen. Die Fig. 3 und 4 zeigen ein Detail der Fig. 1 in vergrößertem Maßstab im Schnitt, wobei der Schnitt gemäß der Linie III-III der Fig. 1 geführt ist.The invention is explained in more detail below with reference to the drawing, in which Fig. 1 shows a view of a support and guide frame in the direction of the longitudinal axis, partly in section, and Fig. '2 shows a section on a smaller scale according to line II-II of Fig. 1 . 3 and 4 show a detail of FIG. 1 on an enlarged scale in section, the section being taken along the line III-III of FIG. 1.

Zwischen den Rollenbahnen 1 und 2 wird ein Strang 3 gestützt und geführt. Die Rollen 4 jeder der Rollenbahnen sind mit Halterungen 5 in Lagerböcke 6 eingesetzt, die an Längsträgern 7, 8 befestigt sind. Damit eine allzu große Durchbiegung der langen und verhältnismäßig dünnen Rollen 4 vermieden wird, sind beim dargestellten Ausführungsbeispiel vier über die Längserstreckung der Rollen verteilt angeordnete Halterungen 5 vorgesehen. Die Längsträger 7 der unteren Rollenbahn sind an Querträgern 9 befestigt und bilden zusammen mit den Querträgern ein erstes Tragwerk 10. Die Längsträger 8 der oberen Rollenbahn sind ebenfalls an Querträgern 11 montiert und bilden zusammen mit diesen ein zweites Tragwerk 12. An den Querträgern 9 des ersten Tragwerkes 10 sind seitlich der Enden der Rollen 4 hohle Streben 13 starr-befestigt, die an ihrem oberen Ende einen Flansch 14 aufweisen. Auf diesem Flansch ruht jeweils ein Ende 15 eines Querträgers 11 des zweiten Tragwerkes 12, u. zw. entweder direkt (bei minimalem Abstand der Rollenbahnen) oder unter Zwischenlage von Beilagscheiben (bei den minimalen Abstand übersteigendem Abstand der Rollenbahnen, Fig. 1). Die Querträger 11 des zweiten Tragwerkes 12 werden an beiden Enden 15 von Zugankern 16 durchsetzt, die mit dem Hohlraum 17 der hohlen Streben 13 fluchten und in den Hohlraum eingesetzt werden können.A strand 3 is supported and guided between the roller conveyors 1 and 2. The rollers 4 of each of the roller tracks are inserted with brackets 5 in bearing blocks 6, which are fastened to side members 7, 8. In order to avoid excessive deflection of the long and relatively thin rollers 4, four brackets 5 are provided in the embodiment shown, which are distributed over the longitudinal extent of the rollers. The longitudinal members 7 of the lower roller conveyor are fastened to cross members 9 and, together with the cross members, form a first support structure 10. The longitudinal members 8 of the upper roller conveyor are also mounted on cross members 11 and together with these form a second support assembly 12. On the cross members 9 of the first The supporting structure 10 is rigidly fastened to the sides of the ends of the rollers 4, hollow struts 13 which have a flange 14 at their upper end. One end 15 of a cross member 11 of the second supporting structure 12 rests on this flange, u. between either directly (with a minimum distance between the roller conveyors) or with washers (with the distance between the roller conveyors exceeding the minimum distance, Fig. 1). The cross members 11 of the second supporting structure 12 are penetrated at both ends 15 by tie rods 16 which are aligned with the cavity 17 of the hollow struts 13 and can be inserted into the cavity.

Die über die Querträger des zweiten Tragwerkes hinausragenden Enden der Zuganker 16 sind jeweils mit einem Bund 18 versehen. Die-ser Bund stützt sich über eine Entlastungseinrichtung 19 entweder direkt oder unter Zwischenlage von Beilagscheiben 20 gegen ein Ende 15 des Querträgers 11 des zweiten Tragwerkes 12 ab.The ends of the tie rods 16 projecting beyond the cross members of the second supporting structure are each provided with a collar 18. This collar is supported by a relief device 19 either directly or with washers 20 interposed against one end 15 of the cross member 11 of the second supporting structure 12.

Oberhalb des Bundes 18 jedes Zugankers 16 ist an einer Verlängerung 21 des Zugankers ein Träger 22 angelenkt, wobei jeweils ein Träger zwei Zuganker 16, die an den Enden 15 jeweils eines Querträgers 11 vorgesehen sind, verbindet. In geringem Abstand 23 von jedem der Zuganker 16 ist ein etwa parallel zu ihm angeordneter Druckmittelzylinder 24 vorgesehen, der einerseits an dem Träger 22 und anderseits an dem Querträger 11 des zweiten Tragwerkes angelenkt ist. Die Druckmittelzylinder 24 (an ihrer Stelle könnte auch eine andere Stelleinrichtung, beispielsweise eine drehbare Spindel etc. vorgesehen sein) liegen jeweils zwischen den Zugankern16.Above the collar 18 of each tie rod 16, a girder 22 is articulated to an extension 21 of the tie rod, one girder connecting two tie rods 16, each of which is provided at the ends 15 of a cross member 11. At a short distance 23 from each of the tie rods 16, an approximately parallel to it pressure medium cylinder 24 is provided, which is articulated on the one hand on the carrier 22 and on the other hand on the cross member 11 of the second structure. The pressure medium cylinders 24 (another actuating device, for example a rotatable spindle etc. could be provided in their place) are each located between the tie rods 16.

Die Entlastungseinrichtung 19 weist zwei Büchsen 25, 26 auf, die mit einander entsprechenden schraubenförmigen Gleitflächen einen Gewindegang bilden. Eine der Büchsen 25, 26 ist gegenüber der anderen Büchse verdrehbar, u. zw. mit Hilfe eines jeweils an einer der beiden Büchsen, die an einander gegenüberliegenden Zugankern 16 angeordnet sind, angelenkten Druckmittelzylinders 27, wodurch die Distanz der äußeren Auflageflächen 28, 29 der Büchsen 25, 26 zwischen Querträger 11 und Bund 18 des jeweiligen Zugankers 16 verändert werden kann. Mittels dieser Büchsen 25, 26, ist es somit möglich, einen Querträger 11 des zweiten Tragwerkes 12 gegen die Streben 13 und somit gegen das erste Tragwerk 10 zu spannen, u. zw. bei im ersten Tragwerk fixierten Zugankern, bzw. die beiden Tragwerke 10, 12 voneinander zu lösen.The relief device 19 has two bushes 25, 26 which form a thread with corresponding helical sliding surfaces. One of the sleeves 25, 26 is rotatable relative to the other sleeve, u. between by means of a pressure medium cylinder 27 articulated on one of the two bushes, which are arranged on mutually opposite tie rods 16, whereby the distance of the outer bearing surfaces 28, 29 of the sleeves 25, 26 between cross member 11 and collar 18 of the respective tie rod 16 changes can be. By means of these bushes 25, 26, it is thus possible to tension a cross member 11 of the second supporting structure 12 against the struts 13 and thus against the first supporting structure 10, u. between. In the case of tie rods fixed in the first supporting structure, or to separate the two supporting structures 10, 12 from one another.

Die Fixierung der Zuganker 16 an den Streben 13 erfolgt mittels einer Renkverbindung 30, die wie folgt gestaltet ist: In den Hohlraum 17 der Streben 13 ist jeweils eine Scheibe 31 drehbar eingesetzt. Der Hohlraum ist nach oben und nach unten durch jeweils eine Platte 32, 33 begrenzt. Die Scheibe 31 weist eine ovale, zentrisch angeordnete Ausnehmung 34 auf, durch die der Zugankerkopf 35, welcher als am verjüngten Ende 36 des Zugankers 16 angeordneter hammerkopfartiger Ansatz 37 ausgebildet ist, hindurchführbar ist. Die Scheibe 31 kann mittels eines in Fig. 4 dargestellten Betätigungshebels 38, der in Bohrungen 39, die am Umfang 40 der Scheibe 31 angeordnet sind, einsetzbar ist, verdreht werden. Als Verdrehanschlag ist ein in eine periphere Nut 41 der Scheibe 31 ragender Bolzen 42 vorgesehen, der an der Strebe 13 montiert ist. Nach außen hin ist der Hohlraum 17, in dem die Scheibe 31 eingesetzt ist, mittels einer abnehmbaren Abdeckplatte 43 verschlossen. An dieser Abdeckplatte 43 ist ein in den Hohlraum 17 ragender Sperrstift 44 befestigt, der bei an der Strebe 13 montierter Abdeckplatte 43 in eine der Bohrungen 39 der Scheibe 31 hineinragt. Der Hohlraum 17, in dem sich die Scheibe 31 befindet, ist zweckmäßig mit Fett gefüllt.The tie rods 16 are fixed to the struts 13 by means of a bayonet connection 30, which is designed as follows: In each case a disk 31 is rotatably inserted into the cavity 17 of the struts 13. The cavity is delimited at the top and bottom by a plate 32, 33 in each case. The disc 31 has an oval, centrally arranged recess 34 through which the tie rod head 35, which is designed as a hammer head-like extension 37 arranged at the tapered end 36 of the tie rod 16, can be passed. The disk 31 can be rotated by means of an actuating lever 38 shown in FIG. 4, which can be inserted in bores 39 which are arranged on the circumference 40 of the disk 31. A pin 42, which projects into a peripheral groove 41 of the disk 31 and is mounted on the strut 13, is provided as the twist stop. The cavity 17, in which the disc 31 is inserted, is closed to the outside by means of a removable cover plate 43. On this cover plate 43, a locking pin 44 projecting into the cavity 17 is fastened, which protrudes into one of the bores 39 of the disk 31 when the cover plate 43 is mounted on the strut 13. The cavity 17 in which the disc 31 is located is advantageously filled with grease.

Die Funktion der Einrichtung ist folgende: Soll das zweite Tragwerk 12 vom ersten Tragwerk 10 abgehoben werden, werden zunächst die Entlastungseinrichtungen 19 betätigt, d.h. die Verspannung der Tragwerke gelöst, worauf nach Abnehmen der Abdeckplatten 43 der Betätigungshebel 38 in eine der Bohrungen 39 der Scheiben 31 eingesetzt wird und die Scheiben aus der Befestigungsposition A, die in Fig. 3 dargestellt ist, in die in Fig. 4 dargestellte Freigabeposition B gedreht werden. Da eine Verschwenkung des Betätigungshebels 38 um 90° nicht möglich ist, muß der Betätigungshebel 38 nacheinander in die Bohrungen 39 der Scheiben 31 gesteckt werden, um eine Verdrehung der Scheiben 31 um volle 90° bewerkstelligen zu können. In der Freigabeposition B fluchtet die ovale Ausnehmung 34 jeder Scheibe 31 mit dem hammerkopfartigen Ansatz 37 des Zugankers 16, sodaß es möglich ist, die Zuganker durch Beaufschlagen der Druckmittelzylinder 24 in das zweite Tragwerk 12 zurückzuziehen. Sodann kann das zweite Tragwerk 12 vom ersten Tragwerk 10 mit Hilfe eines Hallenkranes abgehoben werden.The function of the device is as follows: If the second supporting structure 12 is to be lifted off the first supporting structure 10, the relief devices 19 are first actuated, that is to say the tensioning of the supporting structures is released, after which the actuating lever 38 is removed into one of the bores 39 of the disks 31 after the cover plates 43 have been removed is used and the disks from the fastening position A, which is shown in Fig. 3, are rotated into the release position B shown in Fig. 4. Since a pivoting of the actuating lever 38 by 90 ° is not possible, the actuating lever 38 must be inserted one after the other into the bores 39 of the disks 31 in order to be able to turn the disks 31 by a full 90 °. In the release position B aligns the oval recess 34 of each disc 31 with the hammer head-like extension 37 of the tie rod 16, so that it is possible to pull the tie rods back into the second supporting structure 12 by acting on the pressure medium cylinders 24. Then the second structure 12 can be lifted from the first structure 10 with the aid of an indoor crane.

Mit Hilfe der Zuganker 16 ist es auch möglich, die Rollen 4 der äußeren und der inneren Rollenbahnen 1, 2 in einem großen Abstand voneinander zu halten. Die Vorgangsweise dabei ist folgende: Zuerst wird durch Betätigen der Entlastungseinrichtungen 19 die Verspannung der Tragwerke 10, 12 gelöst. Anschließend werden die Abdeckplatten 43 abgenommen und die Scheiben 31 mit Hilfe des Betätigungshebels 38 in die Freigabeposition B gedreht. Mit Hilfe der Druckmittelzylinder 24 werden die Zuganker 16 zurückgezogen, bis sich die hammerkopfartigen Ansätze 37 oberhalb der Scheibe 31 befinden. Hierauf können nach Zurückdrehen der Scheiben 31 in die Befestigungsposition A die Zuganker 16 wieder soweit abgesenkt werden, bis sie auf den Scheiben 31 aufsitzen. Anschließend können nach Entfernen der Beilagscheiben 20 die Querträger 11 mit Hilfe der Druckmittelzylinder 24 weiter angehoben werden. Ein Fortsatz 45 unterhalb des hammerkopfartigen Ansatzes 37 dient jeweils zur Zentrierung der Zuganker 16 in dieser angehobenen Stellung; außerdem ist er beim Einführen der Zuganker in die Streben 13 vorteilhaft.With the help of the tie rods 16, it is also possible to keep the rollers 4 of the outer and inner roller tracks 1, 2 at a large distance from one another. The procedure is as follows: First, the tensioning of the supporting structures 10, 12 is released by actuating the relief devices 19. The cover plates 43 are then removed and the disks 31 are rotated into the release position B with the aid of the actuating lever 38. With the help of the pressure medium cylinders 24, the tie rods 16 are retracted until the hammer head-like projections 37 are located above the disk 31. After turning the disks 31 back into the fastening position A, the tie rods 16 can be lowered again until they sit on the disks 31. Then, after removing the washers 20, the cross members 11 can be raised further with the aid of the pressure medium cylinders 24. An extension 45 below the hammer head-like extension 37 serves to center the tie rods 16 in this raised position; it is also advantageous when inserting the tie rods into the struts 13.

Zum Lösen der Zugankerbefestigung vom ersten Tragwerk ist es lediglich notwendig, die Abdeckplatten 43 zu demontieren und einen Betätigungshebel 38 zu manipulieren. Beide Teile, Abdeckplatte als auch Betätigungshebel, können sehr leicht gestaltet werden, sodaß die mit dem Lösen bzw. Befestigen der Zuganker am ersten Tragwerk verbundene Arbeit in einfacher Weise durchführbar ist.To release the tie rod fastening from the first supporting structure, it is only necessary to disassemble the cover plates 43 and manipulate an actuating lever 38. Both parts, cover plate and actuating lever, can be designed very easily, so that the work associated with loosening or fastening the tie rods on the first structure can be carried out in a simple manner.

Die Erfindung ist nicht auf das in der Zeichnung dargestellte Ausführungsbeispiel beschränkt, sondern kann in verschiedener Hinsicht modifiziert werden. So ist es möglich, die Scheiben 31 jeweils in den Streben 13 starr anzuordnen und den Zugankerkopf 35 drehbar zu lagern. Weiters ist eine weitgehend beliebige Gestaltung des hammerkopf artigen Ansatzes des Zugankers sowie der korrespondierenden Ausnehmung in der Scheibe denkbar, es muß nur sichergestellt sein, daß der Zugankerkopf einen Teil der Scheibe hintergreift und groß genug zur Aufnahme der auftretenden Zugkräfte gestaltet ist.The invention is not limited to the embodiment shown in the drawing, but can be modified in various ways. It is thus possible to rigidly arrange the disks 31 in the struts 13 and to mount the tie rod head 35 rotatably. Furthermore, a largely arbitrary design of the hammer head-like approach of the tie rod and the corresponding recess in the disk is conceivable, it only has to be ensured that the tie rod head engages behind part of the disk and is large enough to accommodate the tensile forces that occur.

Die erfindungsgemäße Einrichtung ist nicht nur vorteilhaft bei einem Stütz- und Führungsgerüst mit einer Vielzahl von Zugankern, wie in Fig. 2 dargestellt, einsetzbar, sondern kann auch bei einem Stütz- und Führungsgerüst mit lediglich vier an den Ecken desselben angeordneten Zugankern vorgesehen werden, beispielsweise an einem Richtaggregat.The device according to the invention can not only be used advantageously in a support and guide frame with a large number of tie rods, as shown in FIG. 2, but can also be provided in a support and guide frame with only four tie rods arranged at the corners thereof, for example on a straightening unit.
