Description

Die vorliegende Erfindung betrifft Zungenvorrichtungen nach dem Oberbegriff von Anspruch 1 und Schienenweichen nach dem Oberbegriff von Anspruch 15.The present invention relates to switch devices according to the preamble of claim 1 and rail switches according to the preamble of claim 15.

Zungenvorrichtungen für Schienenweichen, insbesondere für Rillenschienen, sind in verschiedenen Ausführen bekannt.Tongue devices for rail switches, in particular for grooved rails, are known in various designs.

Beispielsweise sind entsprechend Fig. 1 Zungenvorrichtungen 10 bekannt mit einer Zunge 12 geringer Höhe und damit auch geringer Eigentragfähigkeit, welche deshalb auf einer durchgehenden Gleitplatte 14 zwischen der Backenschiene 16 und der Beischiene 18 verlegt und damit kontinuierlich gestützt werden müssen. Sie werden als "Flachbettzungenvorrichtungen" bezeichnet. Die an sich durchgehende Gleitplatte 14 ist an der Stelle, wo die Stellvorrichtung an die Zunge 12 angreift, unterbrochen, weil dieser Anschluss mittels eines von unten an die Zunge angeschweißten Anschlussstückes realisiert wird, welches bis in die Zungenvorrichtungskammer 20 unter der Gleitplatte 14 reicht. Durch diese Öffnung in der Gleitplatte 14 kann aller Schmutz und Wasser von der Straßenfahrbahn über die oberseitige Öffnung der Zungenvorrichtung in diese und damit auch in die Zungenvorrichtungskammer 20 eindringen. Zudem ist es normal, durch Spülen die Oberfläche der Gleitplatte 14 regelmäßig zu reinigen. Für das Ableiten des Schmutzes und des Wassers befindet sich in der Grundplatte 22 eine Entwässerungsöffnung (nicht gezeigt), die an Entwässerungseinrichtungen der Straße angeschlossen werden kann. In der Zungenvorrichtungskammer 20 ist zweckmäßig unter der Gleitplatte 14 in einem Hüllrohr 24 ein Heizstab 26 angeordnet.For example, are accordingly Fig. 1 Tongue devices 10 are known with a tongue 12 of low height and thus also low self-supporting capacity, which must therefore be laid on a continuous slide plate 14 between the stock rail 16 and the auxiliary rail 18 and thus have to be continuously supported. They are referred to as "flatbed tongue devices". The slide plate 14, which is continuous in itself, is interrupted at the point where the adjusting device engages the tongue 12, because this connection is realized by means of a connection piece welded to the tongue from below, which extends into the tongue device chamber 20 under the slide plate 14. Through this opening in the sliding plate 14, all dirt and water from the roadway can penetrate into the tongue device via the opening on the top side and thus also into the tongue device chamber 20. In addition, it is normal to regularly clean the surface of the slide plate 14 by rinsing. A drainage opening (not shown), which can be connected to drainage devices in the street, is located in the base plate 22 for draining off the dirt and water. In the tongue device chamber 20, a heating rod 26 is expediently arranged under the sliding plate 14 in a cladding tube 24.

Problematisch ist bei dieser Lösung, dass der in die Zungenvorrichtungskammer 20 eindringende Schmutz mit dem Wasser aus dieser Kammer 20 nicht entfernt werden, so dass sich dort unkontrolliert eine korrosionsfördernde Substanz anreichern kann, welche die Nutzungsdauer der Zungenvorrichtung verkürzt. Es besteht für den Verkehrsbetrieb dahingehend ein Interessenskonflikt, dass für das Funktionieren der Zungenvorrichtung regelmäßig von der Gleitplatte 14 der Schmutz abgespült werden muss und damit gleichzeitig ein Prozess der Korrosion in der Zungenvorrichtungskammer 20 in Gang gesetzt wird, der die Nutzungsdauer der Zungenvorrichtung nachteilig beeinflusst.The problem with this solution is that the dirt entering the tongue device chamber 20 is not removed with the water from this chamber 20, so that a corrosive substance can accumulate there in an uncontrolled manner, which shortens the useful life of the tongue device. There is a conflict of interest for the transport company that for the functioning of the tongue device, the dirt has to be rinsed off regularly from the sliding plate 14 and thus at the same time a process of corrosion is set in motion in the tongue device chamber 20 which adversely affects the useful life of the tongue device.

Weiterhin sind entsprechend Fig. 2 Zungenvorrichtungen 40 bekannt, bei denen die Zungenkonstruktion und ihre Auflage auf einzelnen Stützpunkten 42 von den Vignolweichen der Eisenbahnen übernommen und auf die besonderen Bedingungen der Rillenschienenweichen angepasst wurden. Die dabei eingesetzten Zungen 44 sind dank eines größeren Profilquerschnittes wesentlich höher als Flachbettzungen 12, so dass sie den Namen "Tiefbettzungenvorrichtung" geprägt haben. Der Angriff des Stellsystems erfolgt seitlich an der Zunge 44, so dass für diesen keine besonderen Vorkehrungen hinsichtlich der Zungenauflage erforderlich sind.Furthermore are accordingly Fig. 2 Tongue devices 40 are known in which the tongue construction and its support on individual support points 42 were taken over from the Vignol turnouts of the railways and adapted to the special conditions of the grooved rail turnouts. The tongues 44 used in this case are, thanks to a larger profile cross-section, significantly higher than flat-bed tongues 12, so that they have coined the name "deep-bed tongue device". The actuating system acts on the side of the tongue 44, so that no special precautions are required for this with regard to the tongue support.

Für eindringenden Schmutz und Wasser wird oft ebenfalls eine Öffnung (nicht gezeigt) in der Grundplatte 46 vorgesehen, die aber kaum wirksam werden kann, weil die Einzelstützpunkte 48 (auch "Gleitstuhl" genannt) der Zungenauflagerung einen Abfluss des Schmutzwassers aus der offenen Zungenvorrichtungskammer 50, die zwischen Beischiene 52 und Gleitstuhl 48 gegenüber von der Backenschiene 54 besteht, stark behindern. Um der Korrosion infolge des eingespülten Schmutzes im unteren Teil der Zungenvorrichtungskammer 50 entgegen wirken zu können, ist dessen regelmäßige Entfernung erforderlich, was technologisch kompliziert und damit aufwändig ist. Nachteilig ist weiterhin, dass wegen der fehlenden Gleitplatte eine Heizung 56 an den einzelnen Gleitstühlen 48 erfolgen muss, was Gebrauchsnachteile infolge mangelhafter Wirkung in sich birgt. Eine solche Tiefbettzungenvorrichtung ist beispielsweise in der DE 10 2011 100 511 A1 beschrieben.An opening (not shown) is often also provided in the base plate 46 for penetrating dirt and water, but this can hardly be effective because the individual support points 48 (also called "sliding chair") of the tongue support allow the dirty water to drain out of the open tongue device chamber 50, which exists between the side rail 52 and slide chair 48 opposite the stock rail 54, severely hinder. In order to be able to counteract the corrosion as a result of the dirt washed in in the lower part of the tongue device chamber 50, its regular removal is necessary, which is technologically complicated and therefore expensive. A further disadvantage is that, because of the lack of a sliding plate, a heater 56 has to be provided on the individual sliding chairs 48, which has disadvantages in use due to its inadequate effect. Such a deep-bed tongue device is for example in the DE 10 2011 100 511 A1 described.

Die FR 746 535 A D1 offenbart die Anbindung der Gleitplatte an die Stege der Schienen dadurch, dass an der Gleitplatte Vorsprünge vorgesehen sind, die durch Durchbrechungen der Stege hindurchgreifen, wobei die Vorsprünge mit den Stegen verschweißt sind.the FR 746 535 A D1 discloses the connection of the sliding plate to the webs of the rails in that projections are provided on the sliding plate which reach through openings in the webs, the projections being welded to the webs.

Die DE 552 276 C betrifft eine ähnliche Ausgestaltung, weil auch hier Vorsprünge der Gleitplatte bestehen, die durch Durchbrechungen in den Schienenstegen geführt sind, wobei allerdings die Verschweißung nicht direkt zwischen den Vorsprüngen und den Schienenstegen vorliegen, sondern auf den Vorsprüngen Zwischenplatten angeordnet sind, die sich an den Schienenstegen abstützen, wobei die Vorsprünge mit den Zwischenplatten verschweißt sind.the DE 552 276 C relates to a similar configuration, because here too there are projections of the slide plate which are guided through openings in the rail webs, although the weld is not directly between the projections and the rail webs, but intermediate plates are arranged on the projections, which are supported on the rail webs , wherein the projections are welded to the intermediate plates.

Die EP 0 144 034 A2 betrifft eine Zungenvorrichtung für Rillenschienenweichen, wobei die Zunge auf einem Gleitplattenblock aufliegt. Dieser Gleitplattenblock weist Bohrungen auf und auch in den Schienenstegen sind entsprechende Bohrungen vorgesehen, wobei die Schienenstege mit dem Gleitplattenblock mittels Schraubverbindungen verschraubt sind.the EP 0 144 034 A2 relates to a tongue device for grooved rail switches, wherein the tongue rests on a sliding plate block. This slide plate block has bores and corresponding bores are also provided in the rail webs, the rail webs being screwed to the slide plate block by means of screw connections.

Die DE 10 49 411 B zeigt ebenfalls Durchbrechungen in den Schienenstegen, wobei hier allerdings die Gleitplatte nicht selbst in den Durchbrechungen auf den Schienenstegen aufliegt, sondern auf vorgelagerten Leisten.the DE 10 49 411 B also shows perforations in the rail webs, although here the sliding plate does not itself lie in the perforations on the rail webs, but rather on upstream strips.

Die DE 482 621 C betrifft eine Lösung, bei der Vorsprünge einer Gleitplatte durch Durchbrechungen in den Schienenstegen reichen und die Vorsprünge mit den Schienenstegen außen verschweißt sind, wobei allerdings keine Grundplatte vorgesehen ist.the DE 482 621 C relates to a solution in which the projections of a sliding plate extend through openings in the rail webs and the projections are welded to the rail webs on the outside, although no base plate is provided.

Die DE 853 759 C betrifft eine Lösung mit einer Grundplatte, wobei Gleitstühle vorgesehen sind, die in beliebiger Art und Weise an den Schienenstegen angeordnet sind.the DE 853 759 C relates to a solution with a base plate, with sliding chairs being provided which are arranged in any desired manner on the rail webs.

Aufgabe der vorliegenden Erfindung ist es daher, Zungenvorrichtungen für Schienenweichen so weiterzubilden, dass die oben genannten Nachteile überwunden werden, wobei die Zungenvorrichtung eine höhere Stabilität aufweist. Insbesondere sollen die Zungenvorrichtungen leicht reinigbar und wenig korrosionsanfällig sein. Vorzugsweise sollen sie einen konstruktiv einfachen und kostengünstig herstellbaren Aufbau besitzen.The object of the present invention is therefore to develop tongue devices for rail switches in such a way that the above-mentioned disadvantages are overcome, the tongue device having a higher stability. In particular, the tongue devices should be easy to clean and less susceptible to corrosion. They should preferably have a structurally simple and inexpensive to manufacture structure.

Diese Aufgabe wird gelöst mit der erfindungsgemäßen Zungenvorrichtung nach Anspruch 1 und der erfindungsgemäßen Schienenweiche nach Anspruch 15. Vorteilhafte Weiterbildungen sind in den Unteransprüchen und der Beschreibung angegeben.This object is achieved with the switch device according to the invention according to claim 1 and the rail switch according to the invention according to claim 15. Advantageous further developments are given in the subclaims and the description.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass zwischen Gleitplatte und Grundplatte eine durch die Grundplatten hindurchführende Entwässerung existiert, weil dadurch eine Verschmutzung und Wassereintragung beispielsweise in die Zungenvorrichtungskammer verhindert wird.In an advantageous further development it is provided that between the sliding plate and the base plate there is a drainage through the base plates, because this prevents contamination and water entry into the tongue device chamber, for example.

"Hindurchreichen" meint dabei sowohl ein Enden des Entwässerungsanschlusses auf Höhe der Grundplatte als auch ein Durchdringen der Grundplatte, d.h. ein Hinausgehen über diese."Reaching through" means both an end of the drainage connection at the level of the base plate and a penetration of the base plate, i.e. going beyond it.

Es wird sich bevorzugt um eine Gleitplatte handeln, es können allerdings auch mehrere, ggf. auch beabstandet angeordnete Gleitplatten vorgesehen sein. Außerdem kann die einzelne Gleitplatte ein- oder mehrteilig ausgebildet sein. Sie kann insbesondere auch in Richtung der Längserstreckung der Zungenvorrichtung geteilt ausgebildet sein.It will preferably be a sliding plate, but several sliding plates, possibly also spaced apart, can also be provided. In addition, the individual slide plate can be designed in one or more parts. In particular, it can also be designed to be divided in the direction of the longitudinal extension of the tongue device.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Gleitplatte in Bezug auf die Gleitfläche bis auf den zumindest einen Entwässerungsanschluss geschlossen ausgebildet ist. Dadurch werden Verschmutzungen, insbesondere der Zungenvorrichtungskammer wirksam verhindert.In an advantageous development, it is provided that the sliding plate is designed to be closed with respect to the sliding surface except for the at least one drainage connection. This effectively prevents soiling, in particular of the tongue device chamber.

Allerdings können in der Gleitplatte auch Ausnehmungen vorhanden sein, beispielsweise konstruktiv bedingte Ausnehmungen, wie eine solche, die für den Angriff einer Stellvorrichtung an der Zungenwurzel erforderlich ist.However, there can also be recesses in the sliding plate, for example, structurally determined recesses, such as one that is required for the engagement of an adjusting device on the root of the tongue.

Solche Ausnehmungen können bevorzugt gegenüber der Zungenvorrichtungskammer geschlossen ausgebildet sein, so dass auf diese Weise ein Schmutz- und Wassereintrag durch die Ausnehmung verhindert wird. Es handelt sich als dann bei der Ausnehmung um eine Vertiefung.Such recesses can preferably be designed to be closed with respect to the tongue device chamber, so that in this way the entry of dirt and water through the recess is prevented. The recess is then a depression.

Besonders bevorzugt ist diese Ausnehmungen zugleich als der Entwässerungsanschluss ausgebildet.Particularly preferably, these recesses are also designed as the drainage connection.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass der Entwässerungsanschluss in der Gleitplatte als Durchbrechung ausgebildet ist, wobei die Durchbrechung mit einer Leitung verbunden ist, die mit einer Durchbrechung in der Grundplatte verbunden ist, wobei die Leitung bevorzugt als Entwässerungsrohr ausgebildet ist, das sich durch die Grundplatte hindurch und unter die Grundplatte erstreckt. Damit ist konstruktiv besonders einfach eine in sich geschlossene Entwässerung bereit gestellt, die Verschmutzungen und Korrosion wirksam verhindert.In an advantageous development it is provided that the drainage connection in the sliding plate is designed as an opening, the opening being connected to a line that is connected to an opening in the base plate, the line preferably being designed as a drainage pipe that extends through the Base plate extends through and under the base plate. In this way, a self-contained drainage is provided in a particularly simple manner in terms of construction, which effectively prevents contamination and corrosion.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Entwässerung lückenlos anschließend an die Gleitplatte und durch die Grundplatte hindurch geführt ist, wodurch eine fluide Kommunikation der Entwässerung mit dem Bereich zwischen Gleit- und Grundplatte verhindert ist.In an advantageous further development, it is provided that the drainage is routed seamlessly to the sliding plate and through the base plate, which prevents fluid communication between the drainage and the area between the sliding plate and the base plate.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass durch Backen- und Beischiene, Grundplatte und Gleitplatte eine geschlossene Zungenvorrichtungskammer ausgebildet ist, wobei der Entwässerungsanschluss die Zungenvorrichtungskammer ohne fluide Kommunikation mit der Zungenvorrichtungskammer durchquert, wodurch Verschmutzung und Korrosion der Zungenvorrichtungskammer verhindert wird und außerdem keine zusätzlichen Räume bestehen, die verschmutzen oder korrodieren können.In an advantageous further development it is provided that a closed tongue device chamber is formed by the back and side rails, base plate and slide plate, the drainage connection crossing the tongue device chamber without fluid communication with the tongue device chamber, which prevents contamination and corrosion of the tongue device chamber and there are no additional spaces that can contaminate or corrode.

Wenn beispielsweise eine konstruktiv bedingte Ausnehmung für den Angriff einer Stellvorrichtung an der Zungenwurzel vorhanden ist, könnte diese zugleich mit einer Durchleitung verbunden sein, die mit einer Durchbrechung in der Grundplatte verbunden ist. Dadurch beschränkt sich die für die Entwässerung und die Stellvorrichtung in der Gleitplatte vorzusehende Ausnehmung auf eine einzige Ausnehmung, die beide Funktionen erfüllt. Außerdem könnte dann auch die in sich geschlossene Zungenvorrichtungskammer bestehen, so dass ein Wasser- oder Verschmutzungseintrag auch in diesem Fall vollständig verhindert ist.For example, if there is a design-related recess for the engagement of an adjusting device on the root of the tongue, this could at the same time be connected to a passage that is connected to an opening in the base plate. As a result, the recess to be provided in the slide plate for the drainage and the adjusting device is limited to a single recess which fulfills both functions. In addition, the self-contained tongue device chamber could then also exist, so that the entry of water or contamination is completely prevented in this case as well.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Zunge eine Zungenspitze aufweist und der Entwässerungsanschluss im Bereich der Zungenspitze angeordnet ist. Dann stört die Entwässerungsöffnung keine anderen konstruktiven Details der Zungenvorrichtung. Bevorzugt ist der Entwässerungsanschluss vor der Zungenspitze angeordnet, weil dann die Zunge vollflächig abgestützt werden kann und keine Reibung zwischen der Zungenspitze und den Kanten des Entwässerungsanschlusses erfolgt.In an advantageous development it is provided that the tongue has a tongue tip and the drainage connection is arranged in the region of the tongue tip. Then the drainage opening does not interfere with any other structural details of the tongue device. The drainage connection is preferably arranged in front of the tongue tip because then the tongue can be supported over its entire surface and there is no friction between the tongue tip and the edges of the drainage connection.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass eine Heizung unter der Gleitplatte im Bereich der Zunge angeordnet ist, wobei die Heizung bevorzugt vor dem Entwässerungsanschluss endet, wobei die Heizung insbesondere in der Zungenvorrichtungskammer angeordnet ist, wodurch der wirksame Querschnitt der Entwässerungsöffnung maximal gehalten werden kann, da die Heizung diesen nicht einschränkt.In an advantageous development it is provided that a heater is arranged under the sliding plate in the area of the tongue, the heater preferably ending in front of the drainage connection, the heater being arranged in particular in the tongue device chamber, whereby the effective cross-section of the drainage opening can be kept to a maximum, because the heating does not limit this.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Gleitplatte sich unter der Zunge vollständig zwischen Backenschiene und Beischiene erstreckt. Dadurch werden Bereiche, die verschmutzen oder korrodieren können, vermieden.In an advantageous development it is provided that the slide plate extends completely between the stock rail and the side rail under the tongue. This avoids areas that can contaminate or corrode.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Gleitplatte mit einem Gefälle in Richtung zum Entwässerungsanschluss hin ausgebildet ist. Dann wird besonders effektiv eine Entwässerung der Zungenvorrichtung bewirkt.In an advantageous development it is provided that the sliding plate is designed with a gradient in the direction of the drainage connection. Drainage of the tongue device is then effected particularly effectively.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Gleitplatte auf seitlich vorstehenden Teilen der Backen- und der Beischiene aufliegt, wobei die seitlich vorstehenden Teile bevorzugt durch Ausnehmungen in Backen- und Beischiene, insbesondere als Rillen ausgebildet sind. Dadurch kann die Zungenvorrichtung konstruktiv besonders einfach und maßhaltig hergestellt werden. Anstelle von Rillen können auch Nuten verwendet werden.In an advantageous development it is provided that the sliding plate rests on laterally protruding parts of the jaw and side rails, the laterally protruding parts preferably being formed by recesses in the jaw and side rails, in particular as grooves. As a result, the tongue device can be manufactured in a particularly simple and dimensionally stable manner. Instead of grooves, grooves can also be used.

Die Ausnehmungen nehmen bevorzugt nur maximal die Hälfte der Breite des Steges der Backen- bzw. der Beischiene ein, wodurch die Backen- oder Beischiene eine ausreichende Stabilität behält.The recesses preferably only occupy a maximum of half the width of the web of the back rail or side rail, whereby the back rail or side rail retains sufficient stability.

Erfindungsgemäß weisen die Backenschiene und/oder die Beischiene in ihren Stegen zumindest eine Durchbrechung auf, in der die Gleitplatte auf dem Steg aufliegt, weil dadurch die Auflagefläche für die Gleitplatte vergrößert wird, was die Zungenvorrichtung steifer und haltbarer macht.According to the invention, the stock rail and / or the auxiliary rail have at least one opening in their webs, in which the slide plate rests on the web, because this increases the support surface for the slide plate, which makes the tongue device stiffer and more durable.

Erfindungsgemäß ist weiterhin vorgesehen, dass die Gleitplatte mit der Backenschiene und/oder der Beischiene durchgängig verschweißt ist. Im Bereich der Durchbrechungen kann die Gleitplatte ebenfalls verschweißt sein oder auch nur einfach aufliegen. Die Verschweißung wird also parallel zur Längserstreckung der Gleitplatte durchgängig vorgenommen. Die Auskragungen der Gleitplatte in die Durchbrechung hinein muss dabei nicht gesondert verschweißt werden, kann es allerdings, was die Stabilität noch weiter erhöht.According to the invention it is further provided that the slide plate is continuously welded to the stock rail and / or the auxiliary rail. In the area of the openings, the sliding plate can also be welded or simply rest. The welding is therefore carried out continuously parallel to the longitudinal extension of the sliding plate. The projections of the sliding plate into the opening do not have to be welded separately, but can, which further increases the stability.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die Backenschiene aus einem Walzprofil, einem Strangpressprofil oder einem Knüppel hergestellt ist und ohne Berücksichtigung etwaiger Durchbrechungen die restliche Breite des Backenschienenstegs zumindest 10 mm beträgt, weil dann die Zungenvorrichtung eine besonders hohe Stabilität aufweistIn an advantageous development, it is provided that the stock rail is made from a rolled profile, an extruded profile or a billet and the remaining width of the stock rail web is at least 10 mm without taking into account any openings, because the tongue device then has a particularly high stability

In einer vorteilhaften Weiterbildung ist vorgesehen, dass es sich um eine Tiefbettzungenvorrichtung handelt, wobei die Zunge bevorzugt eine Höhe von mehr als 80 mm, insbesondere größer gleich 100 mm aufweist. Dadurch können auch im Eisenbahnverkehr bekannte Schienenprofile problemlos für Straßenbahnanwendungen verwendet werden.In an advantageous development, it is provided that it is a deep-bed tongue device, the tongue preferably having a height of more than 80 mm, in particular greater than or equal to 100 mm. As a result, rail profiles known in rail traffic can also be used for tram applications without any problems.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass Stellmittel zum Stellen der Zunge vorgesehen sind, die seitlich an die Zunge angreifen. Dadurch kann das Eindringen von Wasser in untere Bereiche der Zungenvorrichtung wirksam verhindert werden, da dort keine zusätzlichen Öffnungen in der Gleitplatte für diese Stellmittel erforderlich sind und beispielsweise eine vollständig gekapselte Zungenvorrichtungskammer eingesetzt werden kann.In an advantageous further development, it is provided that adjusting means are provided for adjusting the tongue, which act on the side of the tongue. In this way, the penetration of water into lower areas of the tongue device can be effectively prevented, since no additional openings in the sliding plate are required there for these adjusting means and, for example, a completely encapsulated tongue device chamber can be used.

In einer vorteilhaften Weiterbildung ist vorgesehen, dass der Entwässerungsanschluss sich über eine Breite von zumindest 50%, bevorzugt von zumindest 65%, insbesondere von zumindest 75% der lichten Weite zwischen Backen- und Beischiene erstreckt. Dadurch ist die Entwässerung besonders effektiv.In an advantageous further development it is provided that the drainage connection extends over a width of at least 50%, preferably of at least 65%, in particular of at least 75% of the clear width between the cheek rail and side rail. This makes drainage particularly effective.

Unabhängiger Schutz wird beansprucht für erfindungsgemäße Schienenweiche mit einer Zungenvorrichtung, die sich dadurch auszeichnet, dass die erfindungsgemäße Zungenvorrichtung eingesetzt ist.Independent protection is claimed for rail switch according to the invention with a switch device which is characterized in that the switch device according to the invention is used.

Während die in den Fig. 1 und 2 gezeigten Zungenvorrichtungen 10, 40 mit ihren Nachteilen schon vorstehend beschrieben worden sind, zeigen Fig. 3 und 4 bevorzugte Ausführungsformen der erfindungsgemäßen Zungenvorrichtung 100, 200, wobei es sich ersichtlich um Tiefbettzungenvorrichtungen 100, 200 handelt. Dabei ist zu beachten, dass die Fig. 3 und 4 nicht die erfindungsgemäß eingesetzten Durchbrechungen und Verschweißungen zeigen.While those in the Fig. 1 and 2 shown tongue devices 10, 40 with their disadvantages have already been described above, show Fig. 3 and 4th Preferred embodiments of the tongue device 100, 200 according to the invention, which obviously are deep-bed tongue devices 100, 200. It should be noted that the Fig. 3 and 4th do not show the openings and welds used according to the invention.

Die in Fig. 3 gezeigte erste bevorzugte Ausführungsform der erfindungsgemäßen Tiefbettzungenvorrichtung 100 weist eine Tiefbettzunge 102 auf, die einstückig, gefräst aus einem Blockprofil mit beidseitigen Vorsprüngen am Zungenende für eine Dreipunktbefestigung auf einer Gleitplatte 104 hergestellt ist. (Alternativ kann sie auch mehrteilig aus einem üblichen Profilstück mit einem Adapter für die Dreipunktverschraubung am Zungenende auf der Gleitplatte 104 hergestellt sein.)In the Fig. 3 The first preferred embodiment shown of the deep-bed tongue device 100 according to the invention has a deep-bed tongue 102 which is manufactured in one piece, milled from a block profile with projections on both sides at the tongue end for three-point fastening on a slide plate 104. (Alternatively, it can also be made in several parts from a conventional profile piece with an adapter for the three-point screw connection at the tongue end on the slide plate 104.)

Die Tiefbettzungenvorrichtung 100 weist weiterhin eine Backenschiene 106 auf, die ein Profil 105C1 mit einer seitlich in den Steg 108 eingearbeiteter (beispielsweise eingefräst) Rille 109 zur Aufnahme der Gleitplatte 104 besitzt.The deep-bed tongue device 100 furthermore has a stock rail 106, which has a profile 105C1 with a groove 109 machined (for example, milled) into the side of the web 108 for receiving the slide plate 104.

Es ist eine übliche Beischiene 110 aus einem zugearbeiteten Rechteckprofil vorgesehen, die eine Nut 112 (beispielsweise eingefräst) zur Aufnahme der Gleitplatte 104 aufweist.A conventional side rail 110 made of a machined rectangular profile is provided, which has a groove 112 (for example, milled) for receiving the slide plate 104.

Die Gleitplatte 104 ist in Bezug auf die lichte Weite LW zwischen der Backenschiene 106 und der Beischiene 110 vollständig die lichte Weite LW überbrückend angeordnet und zwar so, dass sie die Tiefbettzunge 102 vollständig abstützt.The sliding plate 104 is arranged in relation to the clear width LW between the stock rail 106 and the side rail 110, completely bridging the clear width LW, in such a way that it completely supports the drop-bed tongue 102.

Dabei weist die Gleitplatte 104 einen Entwässerungsanschluss 114 auf, der durch eine Öffnung 116 in der Gleitplatte 104 gebildet wird, in der für eine direkte Entwässerung ein Rohrstutzen 118 eingeschweißt ist, der durch eine Öffnung 120 in einer Grundplatte 122 der Tiefbettzungenvorrichtung 100 hindurchreicht und zwar über die Grundplatte 122 hinaus in den nicht näher dargestellten Untergrund 124 der Tiefbettzungenvorrichtung 100. Der Rohrstutzen 118 kann auch mit der Grundplatte 122 verschweißt sein, um ein Eindringen von Feuchtigkeit aus dem Untergrund der Tiefbettzungenvorrichtung 100 in eine durch Gleitplatte 104, Backenschiene 106, Beischiene 110 und Grundplatte 122 gebildete Zungenvorrichtungskammer 126 wirksam zu verhindern.The slide plate 104 has a drainage connection 114, which is formed by an opening 116 in the slide plate 104, in which for direct drainage a pipe socket 118 is welded in, which extends through an opening 120 in a base plate 122 of the deep bed tongue device 100, namely beyond the base plate 122 into the subsurface 124 of the deep bed tongue device 100, not shown in detail. The pipe socket 118 can also be welded to the base plate 122 in order to to effectively prevent moisture from the underground of the deep-bed tongue device 100 from penetrating into a tongue device chamber 126 formed by slide plate 104, stock rail 106, side rail 110 and base plate 122.

Die Zungenvorrichtungskammer 126 erstreckt sich somit im Bereich der Tiefbettzunge 102 vollständig zwischen Backenschiene 106 und Beischiene 110, wodurch die bei Tiefbettzungenvorrichtungen üblicherweise vorhandenen Bereiche 50 (vgl. Fig. 2), die schwer zu reinigen sind, vermieden sind.The tongue device chamber 126 thus extends completely between the stock rail 106 and side rail 110 in the area of the deep bed tongue 102, whereby the areas 50 usually present in deep bed tongue devices (cf. Fig. 2 ) that are difficult to clean should be avoided.

In der Zungenvorrichtungskammer 126 ist eine Heizung 128 mit einem Heizstab in einem Heizungsrohr vorgesehen, die bis vor den Rohrstutzen 118 reicht. Das Heizrohr der Heizung 128 ist an der Unterseite der Gleitplatte 104 befestigt und führt zu einem elektrischen Anschluss im Heizungskasten hinter der Zungenwurzel im Raum zwischen dem Stammgleis und den Zweiggleisschienen (alles nicht gezeigt). Der Rohrstutzen 118 wiederum ist in Bezug auf die Zungenwurzel (nicht gezeigt) vor oder zumindest unter der Zungenspitze 130 angeordnet. Dadurch wird einerseits eine maximale Heizwirkung in Bezug auf die Tiefbettzunge 102 erreicht und andererseits der Querschnitt des Entwässerungsanschlusses 114 nicht beeinträchtigt. Dieser Querschnitte beträgt etwa 75 % der lichten Weite LW zwischen Backenschiene 106 und Beischiene 110.A heater 128 with a heating rod in a heating tube is provided in the tongue device chamber 126 and extends as far as in front of the pipe socket 118. The heating tube of the heater 128 is attached to the underside of the slide plate 104 and leads to an electrical connection in the heater box behind the tongue root in the space between the main track and the branch track rails (all not shown). The pipe socket 118 is in turn arranged with respect to the tongue root (not shown) in front of or at least below the tongue tip 130. As a result, on the one hand, a maximum heating effect in relation to the deep-bed tongue 102 is achieved and, on the other hand, the cross section of the drainage connection 114 is not impaired. This cross-section is approximately 75% of the clear width LW between stock rail 106 and auxiliary rail 110.

Die Tiefbettzungenvorrichtung 100 weist einen Anschluss eines Stellsystems seitlich an der Tiefbettzunge 102 auf, der einteilig oder mehrteilig ausgebildet ist und der bis in den Stellkasten reicht (alle Element jeweils nicht näher dargestellt).The deep-bed tongue device 100 has a connection of an adjusting system on the side of the deep-bed tongue 102, which is formed in one piece or in several parts and which extends into the adjusting box (all elements not shown in detail).

Es ist weiterhin zu erkennen, dass die Zungengeometrie äquivalent zu einer Vignolweiche mit Kreisbogen 132 unterschlagend 134 ausgebildet ist oder auch mit einem Kreisbogen mit Vorbogen ausgebildet sein kann.It can also be seen that the tongue geometry is designed equivalent to a vignole switch with a circular arc 132 subordinate to 134 or can also be configured with a circular arc with a preliminary arc.

Die Zungenvorrichtung 100 kann einteilig als Monoblock, mehrteilig als Blockkonstruktion oder auch mehrteilig in geschweißter Ausführung hergestellt sein.The tongue device 100 can be produced in one piece as a monoblock, in several parts as a block construction or also in several parts in a welded design.

Es ist zu erkennen, dass bei der besonders vorteilhaft ausgebildeten Lösung der Tiefbettzungenvorrichtung 100 eine durchgehende Gleitplatte 104 kombiniert mit einer vollständig durchgehenden Zungenvorrichtungskammer 126 und einem durchgehenden Entwässerungsanschluss 114, der nicht mit der Zungenvorrichtungskammer 126 kommuniziert, eine leichte Reinigbarkeit der Zungenvorrichtung 100 besteht und die Gefahr von Verschmutzung und Korrosion gebannt ist.It can be seen that in the particularly advantageous solution of the deep-bed tongue device 100, a continuous slide plate 104 combined with a completely continuous tongue device chamber 126 and a continuous drainage connection 114, which does not communicate with the tongue device chamber 126, makes the tongue device 100 easy to clean and there is a risk is banned from pollution and corrosion.

In Fig. 4 ist eine zweite bevorzugte Ausführungsform der erfindungsgemäßen Zungenvorrichtung 200 gezeigt, wobei identische Bezugszeichen für identische Elemente verwendet sind.In Fig. 4 a second preferred embodiment of the tongue device 200 according to the invention is shown, identical reference numerals being used for identical elements.

Es ist zu erkennen, dass hier die Gleitplatte 104 sowohl in der Beischiene 110 auf einer Nut 112, als auch in der Backenschiene 202 in einer Nut 204 aufliegt. Da hier also keine Rille109, wie in Fig. 3 vorgesehen ist, sondern eine Nut 204, ist die Backenschiene 202 noch stabiler ausgebildet.It can be seen that here the slide plate 104 rests both in the auxiliary rail 110 on a groove 112 and in the stock rail 202 in a groove 204. Since there is no groove109 here, as in Fig. 3 is provided, but a groove 204, the stock rail 202 is designed to be even more stable.

Auch wenn die Erfindung konkret anhand der Ausbildung einer Tiefbettzungenvorrichtung 100, 200 mit einer Tiefbettzunge mit einer Höhe von etwa 105 mm beschrieben wurde, kann sie auch vorteilhaft im Rahmen von Flachbettzungenvorrichtungen verwendet werden, die Zungenhöhen von kleiner gleich 80 mm, insbesondere von 75 mm aufweisen.Even if the invention has been specifically described on the basis of the design of a deep-bed tongue device 100, 200 with a deep-bed tongue with a height of about 105 mm, it can also be used advantageously in the context of flat-bed tongue devices that have tongue heights of less than or equal to 80 mm, in particular 75 mm .
