Abstract

The cooling bed (1) has a device (12) to transfer the rails (3) from a supply roller table (2) onto the cooling bed, by bending the rails so as to counter the bending which occurs during their cooling. The transfer device has rail rests (25) which can be raised, lowered and moved along. There are counter-holders (37,39) in the middle and end regions of the rail length against the underside and top side of the rail foot. The movements of the rests are controlled so as to produce the required bend.

Description

Die Erfindung betrifft ein Kühlbett für Schienen mit einer Vorrichtung zum Überführen der Schienen von einem zuführenden Rollgang auf das Kühlbett, die aus dem Rollgang in das Kühlbett verschiebbare, heb- und senkbare Auflagen für die Schienen aufweist und zum Verbiegen der Schienen entgegen deren bei der Abkühlung eintretender Verbiegung eingerichtet ist, indem die Verschiebewege der Auflagen entsprechend der gewünschten Verbiegung gesteuert sind.The invention relates to a cooling bed for rails with a device for transferring the Rails from a feeding roller table on the cooling bed, which from the roller table into the Has cooling bed movable, liftable and lowerable supports for the rails and for Bending the rails against the bending that occurs when cooling is set up is by moving the pads according to the desired Bending are controlled.

Ein solches Kühlbett ist aus der DE-A-2 901 811 bekannt. Die Auflagen werden in einer Stellung, in der sie sich zwischen Rollen des Rollganges befinden, über die Transportebene des Rollganges angehoben und nehmen die Schiene auf. Sie bringen die Schiene auf das Kühlbett und legen sie dort ab, indem sie wieder unter die Ebene des Kühlbettes abgesenkt werden. Die auf dem Kühlbett abgelegte Schiene kann dann dadurch vorgebogen werden, daß die Auflagen mit seitlich an ihnen angeordneten Stoßleisten gegen die Schiene gefahren werden und anschließend um unterschiedliche Wege verschoben werden. Nach einer Variante soll die Schiene während der Überführung auf den Auflagen liegend verbogen werden, wofür deren Verschiebewege entsprechend gesteuert sind, d.h. die der Verbiegung dienenden Bewegungen der der Überführung dienenden Bewegung überlagert sind.Such a cooling bed is known from DE-A-2 901 811. The conditions are in one Position in which they are between rollers of the roller table over the transport level of the roller table raised and take up the rail. You bring the rail on the cooling bed and place it there by putting it back under the level of the cooling bed be lowered. The rail placed on the cooling bed can then be pre-bent be that the cushions against the side with bumper strips arranged on them Rail are driven and then moved by different paths. According to a variant, the rail should be on the supports during the transfer are bent horizontally, for which their displacement paths are controlled accordingly, i.e. the bending movements, the transfer movements are superimposed.

Andere, durch Benutzung bekannte Vorrichtungen greifen mit Haken hinter den Schienenfuß und schleifen die Schiene von dem Rollgang auf das Kühlbett herüber. Auch hier ist die Verbiegung der Überführung überlagert; im mittleren Bereich ihrer Länge wird die Schiene um eine größere Strecke bewegt als in den Endbereichen. Im Laufe ihrer Wanderung über das Kühlbett biegt sich die Schiene zurück und schließlich sogar etwas nach der anderen Seite.Other devices known from use engage with hooks behind the rail foot and grind the rail from the roller table onto the cooling bed. Here too the bending of the flyover is superimposed; in the middle of its length the Rail moved a greater distance than in the end areas. During their hike The rail bends back over the cooling bed and finally even slightly the other side.

Die durch die bekannten Vorrichtungen erzeugte Biegung bleibt indessen, insbesondere an den Enden, nicht selten hinter dem gewünschten Maß zurück. Grund dafür ist, daß nach den Enden hin die jenseits einer schiebenden Auflage bzw. eines Hakens verbleibende Länge und damit Masse der Schiene und damit die die Schiene hier zurückhaltende Reibungskraft abnimmt Schließlich reicht die Reibungskraft nicht mehr aus; ein Endabschnitt rutscht, statt sich zu verbiegen. Bei dem erwähnten Vorschlag, die Schiene auf den Auflagen liegend zu verbiegen, ist das in noch stärkerem Maße zu erwarten.
Mit Anschlägen in dem Kühlbett versucht man gelegentlich, die Enden zurückzuhalten. Das ist aber in verschiedenen Beziehungen unbefriedigend. Hauptsächlich besteht eine Knickgefahr.The bend produced by the known devices, however, not infrequently falls short of the desired dimension, particularly at the ends. The reason for this is that after the ends the length remaining beyond a sliding support or a hook and thus the mass of the rail and thus the frictional force retaining the rail here decreases. Finally, the frictional force is no longer sufficient; an end section slips instead of bending. This is to be expected to an even greater extent with the aforementioned proposal to bend the rail lying on the supports.
With stops in the cooling bed one occasionally tries to hold the ends back. However, this is unsatisfactory in various relationships. There is mainly a risk of kinking.

Der Erfindung liegt die Aufgabe zugrunde, eine zuverlässige Vorrichtung zum Überführen und zugleich Biegen der Schienen zu schaffen.The invention has for its object a reliable device for transferring and at the same time to bend the rails.

Gemäß der Erfindung wird dieser Zweck dadurch erfüllt, daß bei einer Vorrichtung der eingangs genannten Art an den Auflagen mindestens in einem mittleren Bereich der Schienenlänge gegen die Unterseite des Schienenfußes gerichtete Gegenhalter und mindestens in Endbereichen der Schienenlänge gegen die Oberseite des Schienenfußes gerichtete Gegenhalter angeordnet sind.According to the invention, this purpose is achieved in that the device type mentioned at the beginning at least in a central area of the Rail length and counterholder directed against the underside of the rail foot at least in end areas of the rail length against the top of the rail foot directed counterholders are arranged.

Während des Transportvorganges wird die Schiene durch Angriff der Gegenhalter ausschließlich am Schienenfuß verbogen, und zwar exakt. Der Schienenkopf stößt an keinen Anschlägen an und erhält keine Schleifspuren. Auch im übrigen ist die Behandlung der, noch rotglühenden und entsprechend weichen, Schiene schonend: Am Schienenfuß entstehen gleichfalls keine Schleifspuren, und der Angriff der Gegenhalter, vorzugsweise mit balligen Berührungsflächen, führt zu keinen störenden Einprägungen.During the transport process the rail is bent only by the attack of the counterhold on the rail foot, and exactly. The rail head does not touch any stops and receives no grinding marks. The rest of the treatment is still red-hot and Correspondingly soft, gentle on the rails: There are also none on the rail foot Grinding marks, and the attack of the counterhold, preferably with spherical contact surfaces, does not lead to disturbing impressions.

In der Regel wird jeweils ein gegen die Unterseite des Schienenfußes gerichteter Gegenhalter und ein gegen die Oberseite des Schienenfußes gerichteter Gegenhalter vorhanden sein, und zwar an allen Auflagen.
Man erhält damit Sicherheit und die Möglichkeit, jeden gewünschten Biegeverlauf einzustellen.
In einer gleichbleibenden Produktion könnte man aber auch hier nur in der einen und dort nur in der anderen Richtung wirkende Gegenhalter vorsehen.As a rule, there will be a counter-holder directed against the underside of the rail foot and a counter-holder directed against the top of the rail foot, on all supports.
This gives you security and the ability to set any desired bend path.
In a constant production, however, one could also provide counterholders acting in one direction and there only in the other direction.

Im Prinzip sind starr an den Auflagen angeordnete Gegenhalter denkbar, die beim Anheben der Auflagen auf der einen bzw. anderen Seite des Schienenfußes neben diesem aufsteigen.
Zweckmäßigerweise ist jedoch wenigstens der in Verschieberichtung vordere Gegenhalter in die Auflage versenkbar, vorzugsweise nach vorne und unten verschwenkbar. Dann ist kein so großer Hub der Auflagen erforderlich, und vor allem kann das Kühlbett auch für andere Walzprofile benutzt werden, die eine durchgehend ebene Auflage benötigen. In principle, counterholders rigidly arranged on the supports are conceivable, which rise when the supports are lifted on one or the other side of the rail foot next to it.
Expediently, however, at least the counter-holder, which is at the front in the direction of displacement, can be countersunk into the support, preferably can be pivoted forwards and downwards. This means that the supports do not have to be lifted so large and, above all, the cooling bed can also be used for other rolled sections that require a continuously flat support.

Die Schwenkbarkeit des Gegenhalters in die Versenkung nach vorne und unten, d.h. in die Wirkstellung nach oben und auf den Schienenfuß zu, bedeutet außerdem die geringste Gefahr von Beschädigungen des Schienenfußes.The swiveling of the counter holder in the sinking forward and down, i.e. in the effective position upwards and towards the rail foot also means minimal risk of damage to the rail foot.

Der in der Verschieberichtung hintere Gegenhalter könnte insofern eher starr sein, als seine Höhenstellung für die Rückverschiebung der Auflage ohne Belang ist und er auch für ein anderes Walzprofil als eine Schiene noch Platz ließe.
Zweckmäßigerweise ist aber auch der in Verschieberichtung hintere Gegenhalter, und zwar gegenläufig zu dem vorderen, verschwenkbar. D.h., er ist durch Verschwenken nach oben und hinten zurückziehbar und durch Verschwenken nach vorne und unten vorschiebbar.
Die beiden Gegenhalter können so wie Daumen und Finger den Schienenfuß fassen, jedoch mit Spiel.The counter support in the direction of displacement could be rather rigid in that its height position is irrelevant for the backward movement of the support and it also leaves space for a rolled profile other than a rail.
Expediently, however, the rear counter-holder in the direction of displacement can also be pivoted, in the opposite direction to the front one. That is, it can be retracted by swiveling upwards and backwards and pushed forward by swiveling it forwards and downwards.
The two counterholders can grip the rail foot like thumb and finger, but with play.

Nach einer weiteren zweckmäßigen Ausgestaltung der Erfindung sind die Gegenhalter einschließlich eines gemeinsamen Antriebes über ein Hebelgestänge in einer relativ zu der übrigen Auflage in waagerechter Richtung verstellbaren Baueinheit angeordnet, die im übrigen vorzugsweise einen Absatz bildet, hinter den der in Verschieberichtung hintere Gegenhalter zurückziehbar ist.
Mit der genannten Verstellbarkeit kann die Lage der beiden Gegenhalter verschiedenen Schienenquerschnitten derart angepaßt werden, daß der Schienenkopf im wesentlichen bündig mit der Auflage abschließt und damit immer eine Schiene dicht an die andere gelegt werden kann. Ferner kann die Auflagefläche verschiedenen Querschnittsgrößen anderer Walzprofile angepaßt werden. Der genannte Absatz bildet für diese einen Anschlag, der sie bei der Beschleunigung am Anfang der Verschiebung mitnimmt.According to a further expedient embodiment of the invention, the counterholders, including a common drive, are arranged via a lever linkage in a unit that is adjustable in the horizontal direction relative to the rest of the support, which otherwise preferably forms a shoulder, behind which the rear counterholder can be retracted in the direction of displacement.
With the adjustability mentioned, the position of the two counterholders can be adapted to different rail cross sections in such a way that the rail head is essentially flush with the support and thus one rail can always be placed close to the other. Furthermore, the contact surface can be adapted to different cross-sectional sizes of other rolled sections. The said paragraph forms a stop for them, which takes them with them when accelerating at the beginning of the shift.

Die Auflagen sind zweckmäßigerweise in der Weise heb- und senkbar, daß sie als Wagen oder Schlitten auf einer unterhalb des Rollganges und des Kühlbettes angeordneten, heb- und senkbaren Führung angeordnet und vorzugsweise mittels eines Kettentriebes verschiebbar sind.The pads are conveniently raised and lowered in such a way that they as Carriages or sledges arranged on a table below the roller table and the cooling bed, Liftable and lowerable guide arranged and preferably by means of a chain drive are movable.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Auflagen durch jeweils einen auf die Schiene gerichteten Entfernungsmesser gesondert in die Stellung, in der sie angehoben werden, einsteuerbar.
Damit können die Auflagen jeweils genau unter die schon auf dem Rollgang etwas verzogen ankommenden Schienen gebracht werden, insbesondere die Gegenhalter. According to a further advantageous embodiment of the invention, the supports can be controlled separately into the position in which they are raised by means of a range finder directed at the rail.
This means that the supports can be placed exactly under the rails that are already slightly warped on the roller table, especially the counterholders.

Nach einer weiteren vorteilhaften und zweckmäßigen Ausgestaltung der Erfindung ist die Verschiebezeit für alle Auflagen gleich gesteuert, wobei den unterschiedlichen Verschiebewegen unterschiedliche Geschwindigkeiten entsprechen. Die Biegevorgänge laufen dann nicht bei unterschiedlichen Abkühlungsgraden der Schiene ab.According to a further advantageous and expedient embodiment of the invention the shift time is controlled equally for all editions, with the different shift paths correspond to different speeds. The bending processes are running then not with different degrees of cooling of the rail.

Zum Überführen der in ausgezogenen Linien auf den Rollen 9 gezeichneten Schiene 3 auf das Kühlbett 1 fährt der Wagen zwischen zwei Rollen 9 in eine Stellung, in der er mit einer Auflage 25 unter der Schiene 3 liegt. Durch Anheben der Führung 14 hebt sich nun die Auflage 25 über die Förderebene des Rollganges 2 und nimmt damit die Schiene auf. Die obere Endstellung ist bei 26 strichpunktiert dargestellt.
Bei dieser oberen Stellung der Führung 14 fährt der Wagen weiter zwischen zwei Balken der Roste 5 und 6. Bei 27 wird dann durch Absenken der Führung 14 das Auflager 25 unter die Tragebene des festen Rostes 5 gesenkt und die Schiene 3 damit auf dem Rost 5 abgesetzt.
Der Wagen 13 mit dem Auflager 25 fährt anschließend zurück.
Von der Stellung 26 bis zur Stellung 27 werden jedoch noch weiter unten angegebene Maßnahmen getroffen.Fig. 2 shows the one end position of the angle lever 21, in which the guide 14 assumes its lower position. The carriage 13 is drawn in its starting position.
In order to transfer the rail 3 drawn in solid lines on the rollers 9 onto the cooling bed 1, the carriage moves between two rollers 9 into a position in which it lies under the rail 3 with a support 25. By lifting the guide 14, the support 25 now rises above the conveying plane of the roller table 2 and thus takes up the rail. The upper end position is shown in dash-dot lines at 26.
In this upper position of the guide 14, the carriage continues between two bars of the grids 5 and 6. At 27, the support 25 is then lowered below the supporting plane of the fixed grate 5 by lowering the guide 14 and the rail 3 is thus placed on the grate 5 .
The carriage 13 with the support 25 then moves back.
From position 26 to position 27, however, measures specified below are taken.

Für diese ist in dem Wagen 13 eine Baueinheit 28 mittels eines Kurbeltriebs 29 o.dgl. in waagerechter Richtung verstellbar angeordnet, deren Einzelheiten in Fig. 3 dargestellt sind. Die Baueinheit 28 ist zwischen den beiden Teilen des, zweigeteilten, Auflagers 25 angeordnet. Der Schnitt der Fig. 2 liegt vor dem Auflager 25 insgesamt und zeigt den Wagen 13 in Seitenansicht. Der Schnitt der Fig. 3 ist zwischen den beiden Teilen des Auflagers 25 durch die Baueinheit 28 gelegt; anders betrachtet ist die vordere von zwei gleichen Seitenwänden 30 der Baueinheit weggebrochen.For this is a unit 28 in the carriage 13 by means of a crank mechanism 29 or the like. arranged in an adjustable horizontal direction, the details of which are shown in FIG. 3 are. The assembly 28 is between the two parts of the, two-part, support 25 arranged. The section of FIG. 2 lies in front of the support 25 as a whole and shows the carriage 13 in side view. 3 is between the two Parts of the support 25 placed by the assembly 28; the front is different broken away from two identical side walls 30 of the assembly.

Zwischen den beiden Seitenwänden 30 sind auf starr mit diesen verbundenen Achsen 31, 32 und 33 ein Winkelhebel 34, ein Winkelhebel 35 und ein hydraulischer oder pneumatischer Antrieb 36 für beide schwenkbar gelagert. Der Antrieb 36 greift an dem einen Arm des Winkelhebels 34 an. Mit dem anderen, einen Gegenhalter 37 bildenden Arm ist der Winkelhebel 35 durch ein gelenkiges Zwischenglied 38 verbunden. Das Zwischenglied 38 greift wiederum an dem einen Arm des Winkelhebels 35 an, während der andere Arm einen Gegenhalter 39 bildet. Between the two side walls 30 are axially rigidly connected to these 31, 32 and 33 an angle lever 34, an angle lever 35 and a hydraulic or pneumatic drive 36 pivotally mounted for both. The drive 36 engages the an arm of the bell crank 34. With the other, forming a counter-holder 37 Arm, the angle lever 35 is connected by an articulated intermediate member 38. The Intermediate member 38 in turn engages one arm of the angle lever 35, while the other arm forms a counter-holder 39.

Gegenhalter 37 bzw. 39 sind die Arme für den Schienenfuß 40, den sie zwischen sich aufnehmen, während der Schienenkopf 41 etwa bündig mit dem Auflager 25 abschließt.
Dies ist, in durchgezogenen Linien gezeichnet, die Wirkstellung der Gegenhalter 37 und 39: Der Gegenhalter 39 liegt mit seinem balligen Ende etwa vor der Mitte der Schienenfußunterseite. Der Gegenhalter 37, der gleichfalls am Ende ballig gestaltet ist, liegt mit seiner kurzen Länge quer vor der Oberseite der einen Schienenfußhälfte.
In der gestrichelt gezeichneten zurückgezogenen Stellung ist der Gegenhalter 37 unter die Oberfläche des Auflagers 25 abgesenkt, und der Gegenhalter 39 ist hinter einen Absatz 42 zurückgezogenen, den ein über das Auflager 25 herausragender Abschnitt der Seitenwände 30 an dem Auflager 25 bildet.Brackets 37 and 39 are the arms for the rail foot 40, which they hold between them, while the rail head 41 is approximately flush with the support 25.
Drawn in solid lines, this is the active position of the counterholders 37 and 39: the counterholder 39 lies with its crowned end approximately in front of the center of the underside of the rail foot. The counter-holder 37, which is also crowned at the end, lies with its short length transversely in front of the top of one rail foot half.
In the retracted position shown in dashed lines, the counter-holder 37 is lowered below the surface of the support 25, and the counter-holder 39 is retracted behind a shoulder 42 which is formed by a section of the side walls 30 on the support 25 which projects beyond the support 25.

Wie ein gestrichelt eingezeichnetes kleineres Schienenprofil 43 erkennen läßt, sind die Gegenhalter 37 und 39 für verschiedene Profilgrößen geeignet. Für das kleinere Schienenprofil 43 würde mittels des Kurbeltriebs 39 o.ä. die Baueinheit 28 weiter nach rechts verstellt werden, bis der Schienenkopf wieder etwa bündig mit dem Auflager 25 abschließt.As can be seen from a smaller rail profile 43 shown in broken lines, these are Brackets 37 and 39 suitable for different profile sizes. For the smaller rail profile 43 would by means of the crank mechanism 39 or the like. the assembly 28 further after to the right until the rail head is again approximately flush with the support 25 completes.

Jedem Wagen 13 ist ein Entfernungsmesser 44 zugeordnet, der die Lage der Schiene 3 im Bereich des betreffenden Wagens feststellt und den Wagen so unter die Schiene fahren läßt, daß das Auflager 25 die Schiene genau an der gewünschten Stelle aufnimmt.
Die Gegenhalter werden dann in ihre Wirkstellung geschwenkt und fassen den Schienenfuß ein. Die Schiene wird dadurch, wenn die verschiedenen Wagen unterschiedlich weit verschoben werden, entsprechend diesen Unterschieden verbogen. Gleichviel, ob an der betreffenden Stelle von der einen oder anderen Seite auf die Schiene gedrückt werden muß: Es ist immer der benötigte Gegenhalter 37 oder 39 vorhanden.Each carriage 13 is assigned a rangefinder 44 which detects the position of the rail 3 in the region of the carriage concerned and allows the carriage to travel under the rail in such a way that the support 25 picks up the rail exactly at the desired location.
The counterholders are then swiveled into their operative position and grip the rail foot. As a result, when the different carriages are moved to different distances, the rail is bent in accordance with these differences. Regardless of whether the rail has to be pressed from one side or the other at the point in question: the required counterhold 37 or 39 is always available.
