Description

Die Erfindung bezieht sich auf eine Rillenschienenzungenvorrichtung in Monoblockbauweise mit Zungenschiene, wobei die Zungenvorrichtung in Monoblockbauweise hergestellt ist und zumindest eine Backenschiene, eine Anschlussschiene und eine Zungenschienenabstützung umfasst, und wobei die Zungenschiene mit der Anschlussschiene mechanisch miteinander verbunden ist.The invention relates to a grooved rail tongue device in monoblock design with a tongue rail, the tongue device being produced in a monoblock design and comprising at least one stock rail, a connecting rail and a tongue rail support, and wherein the tongue rail is mechanically connected to the connecting rail.

Der Begriff Backenschiene, Anschlussschiene, Beischiene umfasst merkmalsmäßig einen Beischienen-, Anschlussschienen- und Backenschienenabschnitt.The term stock rail, connecting rail, auxiliary rail includes a feature of an auxiliary rail, connecting rail and stock rail section.

Zungenvorrichtungen im Monoblockbauweise haben sich umfassend bewährt. Entsprechende Zungenvorrichtungen sind z. B. der DE 101 24 624 C2 oder DE 40 11 523 A1 zu entnehmen. Die Zungenvorrichtungen können dabei aus einem einheitlichen Material oder aus einem oberen aus hochfestem Stahl bestehenden Teil und einem unteren z. B. aus Baustahl bestehenden Teil hergestellt sein. Das Oberteil weist das Zungenbett auf, in dem die Zungenschiene verstellbar angeordnet ist. Das Zungenbett umfasst somit die Backenschiene, die auch als Gleitplatte zu bezeichnenden Zungenschienenabstützung sowie zumindest eine Beischiene. Ferner ist Bestandteil der Zungenvorrichtung ein Abschnitt einer Anschluss- oder Regelschiene, mit der die Zungenschiene innerhalb der Zungenvorrichtung verbunden wird. Dabei haben sich mechanische Verbindungen durchgesetzt, wobei die Zungenschiene und die Anschlussschiene über einen Stumpfstoß ineinander übergehen. Zu beiden Seiten des Stoßes verlaufen sodann mechanische Verbindungselement, wie Laschen, die über die Schienen durchsetzende Schrauben miteinander verbunden werden. Der Stumpfstoß hat den Nachteil, dass ein abrupter Radüberlauf ist gegeben mit der Folge, dass die Kanten im Stoß ausgefahren werden. Es entstehen Überlaufprobleme, wodurch unter anderem auch der Fahrkomfort beeinträchtigt wird.Tongue devices in monoblock construction have proven themselves extensively. Corresponding tongue devices are z. B. the DE 101 24 624 C2 or DE 40 11 523 A1 refer to. The tongue devices can consist of a single material or an upper part made of high-strength steel and a lower z. B. be made of structural steel part. The upper part has the tongue bed in which the tongue rail is adjustably arranged. The tongue bed thus comprises the stock rail, the tongue rail support, which can also be referred to as a sliding plate, and at least one side rail. Furthermore, part of the switch device is a section of a connection or control rail with which the switch rail is connected within the switch device. Mechanical connections have prevailed, with the tongue rail and the connecting rail merging into one another via a butt joint. Mechanical connecting elements, such as straps, which are connected to one another via screws penetrating the rails, then run on both sides of the joint. The butt joint has the disadvantage that the wheel overruns abruptly, with the result that the edges are extended in the joint. Overflow problems arise, which among other things also affects driving comfort.

Um diesen Nachteil zu vermeiden, ist es bekannt, dass Zungenschiene und Anschlussschiene in einem Schrägstoß ineinander übergehen ( EP 0 603 883 A1 , DE 42 44 010 A1 ). Allerdings tritt der Nachteil auf, dass die Spitzen von Zungen- und Anschlussschiene ausbrechen können, so dass häufige Überprüfungen und ggf. notwendige Wartungs- oder Reparaturmaßnahmen im Gleis erforderlich sind.In order to avoid this disadvantage, it is known that the tongue rail and connecting rail merge into one another in an oblique joint ( EP 0 603 883 A1 , DE 42 44 010 A1 ). However, there is the disadvantage that the tips of the tongue and connection rails can break off, so that frequent checks and any necessary maintenance or repair measures on the track are necessary.

Bei Zungenvorrichtungen in Monoblockbauweise können Zungen- und Anschlussschiene über eine Klemmeinrichtung, einen sogenannten Zungenadapter, kraftschlüssig mechanisch miteinander verbunden werden ( DE 101 14 683 A1 ).In the case of switch devices in monoblock construction, the switch and connection rails can be mechanically connected to one another in a force-locking manner using a clamping device, a so-called tongue adapter ( DE 101 14 683 A1 ).

Auch sind Monoblockkonstruktionen bekannt, bei denen der Block sich über die Länge des Zungenbettes sowie zumindest über eine Seite von diesem hinaus erstreckt (siehe DE 10 2010 037 110 A1 ).Monoblock constructions are also known in which the block extends over the length of the tongue bed and at least over one side of it (see DE 10 2010 037 110 A1 ).

Der DE 44 10 200 C1 ist eine Abzweigungsvorrichtung einer Weiche mit S-förmigem Stoß zu entnehmen.Of the DE 44 10 200 C1 a junction device of a switch with an S-shaped joint can be seen.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Zungenvorrichtung der eingangs genannten Art so weiterzubilden, dass ein hoher Fahrkomfort beim Durchfahren der Zungenvorrichtung gegeben ist. Auch soll ein Verschleiß am Radüberlaufbereich zwischen Zungen- und Anschlussschiene im Vergleich zum Start verringert werden.The present invention is based on the object of developing a switch device of the type mentioned at the outset in such a way that a high level of driving comfort is provided when driving through the switch device. Wear on the wheel overrun area between the tongue and connection rails should also be reduced compared to the start.

Zur Lösung der Aufgabe sieht die Erfindung im Wesentlichen vor, dass die Zungenschiene und die Anschlussschiene über einen im Horizontalschnitt S-förmigen Stoß ineinander übergehen, und dass die Zungenschiene über einen Wanderschutz gegen eine Bewegung in Längsrichtung gesichert ist, der sich abschnittsweise sowohl in einer die Zungenschiene abstützenden Gleitplatte als auch in der Zungenschiene erstreckt, wobei der Wanderschutz benachbart zum S-förmigen Stoß verläuft.To achieve the object, the invention essentially provides that the tongue rail and the connecting rail merge into one another via a joint that is S-shaped in the horizontal section, and that the tongue rail is secured against movement in the longitudinal direction by means of a traveling protection device, which extends in sections both in one direction Tongue rail supporting sliding plate and extends in the tongue rail, wherein the walking protection runs adjacent to the S-shaped joint.

Erfindungsgemäß wird bei einer in Monoblockbauweise hergestellten Zungenvorrichtung ein S-förmiger Stoß zum Verbinden von Anschlussschiene und Zungenschiene benutzt, der die Verbindung zwischen den Schienenabschnitten erleichtert bzw. verbessert. Durch den Verlauf des Stoßes wird beim Durchfahren dieses der Fahrkomfort verbessert. Es steht ein verschleißarmer Radüberlauf zur Verfügung, dessen Stabilität insbesondere aus dessen stumpfwinkliger S-Form bzw. dem Ausbleiben von Materialspitzen im Vergleich zu Schrägstößen begründet ist. Gleichzeitig stellt der S-Stoß sicher, dass eine zweiteilige Radlauffläche über die Länge des sich in Schienenrillenlängsrichtung verlaufenden Abschnitts des S-Stoß zur Verfügung steht, durch die das Ausbrechen von Rändern oder sonstige Schädigungen dem Grunde nach verhindert wird.According to the invention, an S-shaped joint is used for connecting the connecting rail and the tongue rail in a tongue device produced in a monoblock construction, which joint facilitates or improves the connection between the rail sections. The course of the impact improves driving comfort when driving through it. There is a low-wear wheel overrun available, the stability of which is due in particular to its obtuse-angled S-shape or the absence of material peaks compared to angled joints. At the same time, the S-joint ensures that a two-part wheel running surface is available over the length of the section of the S-joint running in the longitudinal direction of the rail grooves, which basically prevents edges from breaking out or other damage.

Ungeachtet dessen bleiben die Vorteile der Monoblockrillenschienenzungenvorrichtungen im Hinblick der Möglichkeit der Auswahl gewünschter Materialien von Zungen- und Anschlussschienen beibehalten, wobei aufgrund der mechanischen Verbindung, d.h. des Fixierens durch Klemmen in einem sogenannten Zungenadapter, die Möglichkeit eines problemlosen Austauschs der Zungenschiene beibehalten wird. Dabei wird die Zungenschiene insbesondere durch Keilelemente fixiert, wie diese z. B. der DE 42 44 010 A1 bzw. der EP 0 603 883 A1 zu entnehmen sind.Regardless of this, the advantages of the monoblock grooved rail tongue devices with regard to the possibility of selecting the desired materials for tongue and connecting rails remain, with the possibility of easy replacement of the tongue rail being retained due to the mechanical connection, ie fixing by clamping in a so-called tongue adapter. The tongue rail is fixed in particular by wedge elements, such as these, for. B. the DE 42 44 010 A1 or the EP 0 603 883 A1 can be found.

Insbesondere ist vorgesehen, dass in dem Monoblock im endstirnseitigen Bereich der Anschlussschiene eine einer S-Form folgende Anlagefläche herausgearbeitet, wie herausgefräst, ist, an der eine geometrisch entsprechend ausgebildete Gegenfläche der Zungenschiene zur Bildung des S-förmigen Stoßes anliegt.In particular, it is provided that a contact surface following an S-shape is machined, as milled out, in the monoblock in the end face area of the connecting rail, on which a geometrically correspondingly designed counter surface of the tongue rail rests to form the S-shaped joint.

Bevorzugterweise ist in Längsrichtung der Anschlussschiene verlaufender Längsschenkel des Stoßes 5 bis 15-fach länger als jeweiliger von dem Längsschenkel ausgehender Querschenkel des Stoßes.Preferably, the longitudinal limb of the joint extending in the longitudinal direction of the connecting rail is 5 to 15 times longer than the respective transverse limb of the joint extending from the longitudinal limb.

Des Weiteren zeichnet sich die Erfindung dadurch aus, dass der S-förmige Stoß aus einem in Längsrichtung der Anschlussschiene verlaufenden Längsschenkel und Querschenkeln besteht, die einen bogenförmigen Verlauf aufweisen.Furthermore, the invention is characterized in that the S-shaped joint consists of a longitudinal limb running in the longitudinal direction of the connecting rail and transverse limbs which have an arcuate course.

Um eine einfache jedoch sichere Verbindung herzustellen, schlägt die Erfindung vor, dass die Zungenschiene über zumindest ein Keilelement, wie Keilklemmplatte, kraftschlüssig mit der Anschlussschiene verbunden ist.In order to establish a simple but secure connection, the invention proposes that the tongue rail is connected to the connecting rail in a force-locking manner via at least one wedge element, such as a wedge clamping plate.

Hierzu kann in Längsrichtung der Zungenvorrichtung eine T-Nut zur Aufnahme einer oder mehrerer Muttern einer oder mehrerer Schrauben verlaufen, über die das Keilelement zum kraftschlüssigen Verbinden der Zungenschiene mit der Anschlussschiene anziehbar ist. Des Weiteren sollte der Monoblock zumindest in seinem die Backenschiene, die Anschlussschiene, die Beischiene und die Zungenschienenabstützung umfassenden Bereich aus hochfestem Stahl wie Bainit, Manganhartstahl, vergütetem Schienenstahl (R350HT), vergütetem Feinkornbaustahl, z.B. Dilidur, Hardox, XAR in Güten 400-500, bestehen.For this purpose, a T-groove for receiving one or more nuts of one or more screws can run in the longitudinal direction of the tongue device, via which the wedge element can be tightened for non-positive connection of the tongue rail with the connecting rail. Furthermore, the monoblock should be made of high-strength steel such as bainite, manganese steel, tempered rail steel (R350HT), tempered fine-grain structural steel, e.g. Dilidur, Hardox, XAR in grades 400-500, at least in its area comprising the stock rail, the connecting rail, the auxiliary rail and the tongue rail support. exist.

Die Zungenschiene ist über einen Wanderschutz gegen eine Bewegung in Längsrichtung gesichert, der sich abschnittsweise sowohl in der Zungenabstützung als auch in der Zungenschiene erstreckt.The tongue rail is secured against movement in the longitudinal direction by a walking protection which extends in sections both in the tongue support and in the tongue rail.

Weitere Vorteile der Erfindung ergeben sich nicht nur aus den Ansprüchen, sondern auch aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels.Further advantages of the invention emerge not only from the claims, but also from the following description of a preferred exemplary embodiment.

In den Figuren, in den grundsätzlich gleiche Elemente mit gleichen Bezugszeichen gekennzeichnet sind, ist eine Zungenvorrichtung 10 mit Zungenschiene 12 dargestellt. Die Zungenvorrichtung 10 ist in Monoblockbauweise hergestellt, d.h. einteilig. Einteilig schließt dabei allerdings die Möglichkeit ein, dass das Unterteil der Zungenvorrichtung 10 aus einem anderen Material als das insbesondere aus hochfestem Stahl bestehende Oberteil hergestellt ist. Ungeachtet dessen handelt es sich um eine Monoblockbauweise, da die dem starken Verschleiß ausgesetzten Bereiche einstückig ausgebildet sind und insbesondere aus hochfestem Stahl bestehen. Ein Herausfräsen aus einem Block zur Herstellung des Monoblocks ist möglich.In the figures, in which basically the same elements are identified with the same reference numerals, a tongue device 10 with tongue rail 12 is shown. The tongue device 10 is made in a monoblock construction, i.e. in one piece. One-piece, however, includes the possibility that the lower part of the tongue device 10 is made of a different material than the upper part, which in particular consists of high-strength steel. Regardless of this, it is a monoblock design, since the areas exposed to heavy wear are formed in one piece and in particular consist of high-strength steel. Milling out of a block to produce the monoblock is possible.

Die Zungenvorrichtung 10 weist eine Backenschiene 14, eine Beischiene 16, einen Abschnitt einer Anschlussschiene 18 sowie eine auch als Zungenschienenabstützung zu bezeichnende Gleitplatte 23 auf, auf der die Zungenschiene 12 verstellbar angeordnet ist. Insoweit wird auf bekannte Konstruktionen verwiesen.The tongue device 10 has a stock rail 14, an auxiliary rail 16, a section of a connecting rail 18 and a sliding plate 23, also known as a tongue rail support, on which the tongue rail 12 is adjustably arranged. In this regard, reference is made to known constructions.

Die Zungenschiene 12 ist in ihrem Wurzelbereich mit der Anschlussschiene 18 mechanisch verbunden, und zwar über einen S-Stoß 20, wie die Draufsicht in Fig. 2 verdeutlicht. Hierzu ist aus dem Monoblock, und zwar von dem Anschlussschienenabschnitt 18 endseitig ein Bereich herausgefräst, um im Horizontalschnitt eine S-förmige Anlagefläche 19 zur Verfügung zu stellen, an der flächig eine geometrisch angepasste Anlagefläche 21 der Zungenschienenwurzel anliegt (Fig. 4). In der Draufsicht wird dies durch eine S-förmig verlaufende Linie 22 verdeutlicht. Die Stoßflächen verlaufen in Richtung der Hochachse des Monoblocks.The tongue rail 12 is mechanically connected in its root area to the connecting rail 18, specifically via an S-joint 20, like the top view in FIG Fig. 2 made clear. For this purpose, an area is milled out of the monoblock, namely from the end of the connecting rail section 18, in order to provide an S-shaped contact surface 19 in horizontal section, on which a geometrically adapted contact surface 21 of the tongue rail root rests flat ( Fig. 4 ). This is illustrated in the plan view by an S-shaped line 22. The abutting surfaces run in the direction of the vertical axis of the monoblock.

Damit die Zungenschiene 12 kraftschlüssig mit der Anschlussschiene 18 verbunden ist, sind entsprechend den Schnittdarstellungen in Fig. 5 und 6 Keilklemmelemente 24 vorgesehen, die über Schrauben 26, 28 in Richtung Boden der Zungenvorrichtung 10 anziehbar sind, um die gewünschte Klemmwirkung und damit die kraftschlüssige Verbindung herzustellen. Zum Anziehen der Schrauben greifen diese mit ihren Gewinden in Muttern 30, 32 ein, die in T-förmige Nuten verlaufen, die im Bodenbereich der Zungenvorrichtung 10 verlaufen. Die entsprechende Nut ist in den Fig. 5 und 6 mit dem Bezugszeichen 34 gekennzeichnet.In order for the tongue rail 12 to be positively connected to the connecting rail 18, according to the sectional views in FIG Figures 5 and 6 Wedge clamping elements 24 are provided which can be tightened via screws 26, 28 in the direction of the bottom of the tongue device 10 in order to produce the desired clamping effect and thus the non-positive connection. To tighten the screws they engage with their threads in nuts 30, 32, which run in T-shaped grooves in the bottom area of the Tongue device 10 run. The corresponding groove is in the Figures 5 and 6 marked with the reference number 34.

Um ein Längswandem der Zungenschiene 12 zu vermeiden, kann ein Wanderschutz 38 vorgesehen sein, der sowohl in die Gleitplatte 20 als auch in die zugewandte Unterseite 40 der Zungenschiene 12 eingreift. Hierzu sind entsprechende Aussparungen 42, 44 in der Gleitplatte 20 bzw. in der Unterseite 40 der Zungenschiene 12 vorgesehen.In order to avoid a longitudinal wall of the tongue rail 12, a wander protection 38 can be provided which engages both in the slide plate 20 and in the facing underside 40 of the tongue rail 12. For this purpose, corresponding recesses 42, 44 are provided in the slide plate 20 or in the underside 40 of the tongue rail 12.

Der Wanderschutz 38 verläuft dabei in unmittelbarer Nähe des Stoßes 20, also in einem Bereich, in dem die Zungenschiene 12 nicht oder im Wesentlichen nicht gebogen wird.The walking protection 38 runs in the immediate vicinity of the joint 20, that is to say in an area in which the tongue rail 12 is not or substantially not bent.

In der Fig. 8 ist noch einmal in vergrößerter Darstellung die Rillenschienenzungenvorrichtung in Blockbauweise mit herausgenommener, allerdings in einer um 90 Grad um ihre Längsachse gedreht dargestellter Zungenschiene 12 wiedergegeben. Man erkennt die S-förmige Anlagefläche 19 für den S-Stoß, die im Anschlussschienenabschnitt 18 herausgearbeitet ist, wobei der in Längsrichtung der Anschlussschiene verlaufende Abschnitt 5 - 15fach länger als der jeweilige von den Längsschenkeln ausgehende Querschenkel ist, der bogenförmig verläuft, wie die Zeichnung verdeutlicht. Auch ist die Aussparung 42 in der Gleitplatte 23 erkennbar, in die der Wanderschutz 38 eingesetzt wird, der sich abschnittsweise in der Gleitplatte 23 und der Zungenschiene 12 erstreckt.In the Fig. 8 the grooved rail tongue device is shown once again in an enlarged representation in block design with the tongue rail 12 removed, but shown rotated by 90 degrees about its longitudinal axis. The S-shaped contact surface 19 for the S-joint can be seen, which is worked out in the connecting rail section 18, the section running in the longitudinal direction of the connecting rail being 5-15 times longer than the respective transverse limb extending from the longitudinal limbs, which is curved, as shown in the drawing made clear. The recess 42 in the sliding plate 23, into which the walking protection 38 is inserted, which extends in sections in the sliding plate 23 and the tongue rail 12, can also be seen.

Durch den Verlauf der Anlagefläche 19 und der entsprechend angepassten Anlagefläche 21 in der Zungenschienenwurzel ergibt sich der S-Stoß, der aus dem in Längsrichtung der Anschlussschiene 18 verlaufenden Längsschenkel und von dessen Enden ausgehenden Querschenkeln besteht. Folglich weist die Anlagefläche 29 und entsprechend die Anlagefläche 21 in der Zungenschienenwurzel einen in Längsrichtung der Anschlussschiene 18 verlaufenden Längsabschnitt 25 und von dessen Enden ausgehende Abschnitte 27, 29 auf, die bogenförmig verlaufen.The course of the contact surface 19 and the correspondingly adapted contact surface 21 in the tongue rail root results in the S-joint, which consists of the longitudinal limb extending in the longitudinal direction of the connecting rail 18 and the transverse limbs extending from its ends. Consequently, the contact surface 29 and correspondingly the contact surface 21 in the tongue rail root have a longitudinal section 25 running in the longitudinal direction of the connecting rail 18 and sections 27, 29 extending from its ends, which run in an arc.

Aufgrund der Länge des Abschnitts 25, also des Längsschenkels des S-Stoßes 20, wird eine relativ lange zweiteilige Radlauffläche zur Verfügung gestellt, durch die der Fahrkomfort erhöht wird. Diesbezügliche zweiteilige Radlaufflächen sind bei einem Schrägstoß ausgeschlossen.Due to the length of the section 25, that is to say the longitudinal leg of the S-joint 20, a relatively long two-part wheel running surface is made available, by means of which the driving comfort is increased. Related two-part wheel treads are excluded in the event of an angled joint.
