Abstract

A grooved rail switch with a tongue rail device includes a tongue rail displaceably supported on a torsion-stiff support box for movement between a stock rail and a switch rail. The support box is made up of an upper slide plate, a lower bottom plate and flat bars extending between and welded to the slide plate and bottom plate. High strength bolts secure the stock rail to one side of the support box and the switch rail to the other side.

Description

Die Erfindung betrifft eine Zungenvorrichtung für Rillenschienenweichen, wobei die Zunge zwischen der Backenschiene und der Bei schiene auf einer Gleitplatte mittels einer Stellvorrichtung verschiebbar ist.The invention relates to a tongue device for grooved rail switches, the tongue between the stock rail and the case of rail on a sliding plate is displaceable by means of an adjusting device.

Diese Gleitplatte wird meist mit dem Steg der Backen- und der Beischiene durch Schweißnähte verbunden. Zur Erhöhung der Stabilität weisen dabei beide Schienen im Stegbereich eine Auflage in Form einer eingewalzten Schulter oder einer aufgeschweißten Leiste auf, auf welche die Gleitplatte aufgelegt und dann verschweißt wird. Die Backenschiene und die Beischiene liegen auf einer Grundplatte auf und sind mit dieser ebenfalls durch Schweißnähte verbunden. Eine solche Konstruktion ist im Gebrauchsmuster DE-U-69 16 985, Figur 2, beschrieben.This slide plate is usually connected to the web of the cheek rail and the side rail by means of weld seams. To increase the stability, both rails have a support in the form of a rolled-in shoulder or a welded-on strip in the web area, onto which the sliding plate is placed and then welded. The stock rail and the side rail rest on a base plate and are also connected to it by welds. Such a construction is described in utility model DE-U-69 16 985, Figure 2.

Diese auch heute noch übliche Konstruktion ist aber in mehrfacher Weise nachteilig : So benötigt man beispielsweise für die Backenschiene und die Beischiene besondere Walzprofile, die jedoch unverhältnismäßig teuer sind, da sie nur in begrenzten Längen benötigt und gesondert hergestellt werden müssen. Da der Hersteller dieses Profils die Walzung aber erst ab einer bestimmten Mindestmenge durchführen kann, ist der Weichenhersteller zu langfristiger Disponierung und zu einer aufwendigen Lagerhaltung dieser speziellen Profile gezwungen.This construction, which is still common today, is disadvantageous in several ways: For example, special roller profiles are required for the stock rail and the side rail, but these are disproportionately expensive because they are only required in limited lengths and have to be manufactured separately. However, since the manufacturer of this profile can only roll from a certain minimum quantity, the switch manufacturer is forced to dispose of these special profiles in the long term and to keep them in storage.

Ein weiterer Nachteil dieser Zungenbereichskonstruktion besteht darin, daß die Unterlagsplatte (Grundplatte), mit der die Backenschiene und die Beischiene verschweißt sind, etwa 15 mm dick ist, so daß der Zungenbereich um die Dicke dieser Unterlagsplatte höher als die anschließenden Gleisschienen ist. Beim Einbau des Zungenbereichs muß diese Differenz durch zusätzliche Baumaßnahmen wieder ausgeglichen werden.Another disadvantage of this tongue area construction is that the base plate (base plate) to which the stock rail and the side rail are welded is approximately 15 mm thick, so that the tongue area is higher than the subsequent track rails by the thickness of this base plate. When installing the tongue area, this difference must be compensated for by additional construction measures.

Die Backenschiene mit dem erforderlichen speziellen Walzprofil (Typbezeichnung BA 75) hat üblicherweise einen durchschnittlichen Kohlenstoffgehalt von 0,6 %, so daß eine Verschweißung nur nach ausreichender Vorwärmung durchgeführt werden kann. Selbst bei dieser Vorwärmung und auch bei sorgfältig durchgeführter Schweißung besteht die Gefahr eines Anrisses im Bereich der Backenschiene jeweils an den Enden der Unterlagsplatte, weil in diesem Bereich die Schweißnaht eine Kerbwirkung ausübt. Die Gefahr der Bildung weiterer Anrisse ist beim unvermeidlichen Richten des Zungenbereichs nach der Schweißung gegeben. Einer Rationalisierung der Schweißarbeiten durch Automatisieren steht die schlechte Zugänglichkeit der Schweißnähte zwischen Backen- bzw. Leitschiene und der Gleitplatte entgegen.The stock rail with the required special rolled profile (type designation BA 75) usually has an average carbon content of 0.6%, so that welding can only be carried out after sufficient preheating. Even with this preheating and also with careful welding, there is a risk of tearing in the area of the stock rail at the ends of the base plate, because in this area the weld seam has a notch effect. There is a risk of further cracks forming if the tongue area is inevitably straightened after welding. A rationalization of the welding work through automation is countered by the poor accessibility of the weld seams between the stock or guide rail and the sliding plate.

Wegen des beim Schweißen der Konstruktion eintretenden Verzuges der Vorrichtung gestaltet sich die Montage des Zungenbereichs sehr aufwendig. Zunge und Gleitplatte müssen sorgfältig einander angepaßt werden, damit eine gleichmäßige, durchgehende Auflage der Zunge gewährleistet ist. Dies erfordert einen erheblichen Aufwand an Schleifarbeiten.Because of the distortion of the device that occurs during the welding of the construction, the assembly of the tongue area is very complex. The tongue and slide plate must be carefully matched to one another so that an even, continuous support of the tongue is ensured. This requires a considerable amount of grinding work.

Es sind ferner Zungenvorrichtungen bekannt, bei denen die Gleitplatte mit den Stegen der Backenschiene und der Beischiene verschraubt sind. Derartige Konstruktionen können der DE-C-826 307 und der DE-C-9 44 255 (Patentanmeldung G 15126 V/19a) entnommen werden. Diese Konstruktionen haben aber den Nachteil, daß sich die Schraubverbindungen, insbesondere bei nicht planer Auflage der Backenschiene und der Beischiene auf dem Gleisbett, im Lauf der Zeit lösen und ein sicherer Fahrbetrieb nicht mehr gegeben ist. Im übrigen müssen auch hier die inneren Stegseiten der Backenschiene und der Beischiene mit Stegen oder Schultern versehen sein, damit die Gleitplatte aufgelegt werden kann:Tongue devices are also known in which the slide plate is screwed to the webs of the stock rail and the side rail. Such constructions can be found in DE-C-826 307 and DE-C-9 44 255 (patent application G 15126 V / 19a). However, these constructions have the disadvantage that the screw connections, in particular when the stock rail and the side rail do not rest on the track bed, become loose over time and safe driving operation is no longer ensured. Otherwise, the inner web sides of the stock rail and the side rail must also be provided with webs or shoulders so that the sliding plate can be placed on:

Derartige durch Verschraubung fixierte Konstruktionen haben sich deshalb bei den Straßen- bzw. Stadtbahnen des öffentlichen Nahverkehrs nicht durchsetzen können.Such constructions fixed by screwing have therefore not been able to establish themselves on trams or light rail vehicles in local public transport.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Zungenvorrichtung zu schaffen, bei der die vorgenannten Nachteile abgestellt werden. Dabei soll die große Stabilität der Schweißkonstruktion erhalten bleiben. Die geforderte Zungenvorrichtung soll unter Verwendung üblicher Profile hergestellt werden können, und es sollen insbesondere Profile verwendet werden, welche in gut schweißbaren Stahlgüten erhältlich sind.The present invention has for its object to provide a tongue device in which the aforementioned disadvantages are eliminated. The great stability of the welded construction should be preserved. The required tongue device should be able to be produced using conventional profiles, and in particular profiles should be used which are available in weldable steel grades.

Überraschenderweise hat sich nun gezeigt, daß die der Erfindung zugrunde liegende Aufgabe mit einer Konstruktion gelöst werden kann, bei der die Gleitplatte und eine ihr entsprechende Unterlagsplatte mit seitlich angeordneten Flacheisen zu einem verwindungssteifen Zungenauflagekasten verschweißt sind, mit dem die Backenschiene und die Beischiene mittels hochfester Schrauben verschraubt sind.Surprisingly, it has now been found that the object on which the invention is based can be achieved with a construction in which the slide plate and a corresponding base plate are welded to laterally arranged flat bars to form a torsion-resistant tongue support box with which the stock rail and the side rail are fastened by means of high-strength screws are screwed.

Der erfindungsgemäßen Konstruktion liegt somit die Überlegung zugrunde, die Gleitplatte und die Unterlagsplatte, die nach dem Stand der Technik üblicherweise mit der Backenschiene und der Leitschiene einen festen Rahmen bilden, aufzulösen und eine separate Einheit zu bilden. Diese separate Einheit in Form eines verwindungssteifen Zungenauflagekastens wird entsprechend der Erfindung durch die Gleitplatte und die ihr entsprechend geformte Unterlagsplatte zusammen mit den seitlich angeordneten Flacheisen gebildet, die durch Schweißnähte miteinander verbunden sind. Die vertikal angeordneten Flacheisen übernehmen somit die abstützende Aufgabe der Backen- und Leitschiene.The construction according to the invention is therefore based on the idea of dissolving the slide plate and the base plate, which according to the prior art usually form a fixed frame with the stock rail and the guide rail, and to form a separate unit. This separate unit in the form of a torsion-resistant tongue support box is formed according to the invention by the slide plate and the correspondingly shaped base plate together with the laterally arranged flat bars which are connected to one another by welds. The vertically arranged flat bars therefore take on the supporting role of the stock and guide rails.

Für die Unterlagsplatte und die vertikal stehenden Flacheisen können Baustähle nach DIN 17 100 bis zu einem Kohlenstoffgehalt von 0,25 % verwendet und ohne Vorwärmung geschweißt werden. Für die Gleitplatte ist aufgrund ihrer Belastung die Verwendung einer verschleißfesten Stahlqualität notwendig. Hierfür haben sich legierte Stähle bewährt, die hohe Festigkeit bei guter Zähigkeit und gute Verschleißeigenschaften bei Schweißeignung auch ohne Vorwärmung aufweisen.Structural steels according to DIN 17 100 up to a carbon content of 0.25% can be used for the base plate and the vertically standing flat bars and welded without preheating. Due to their load, the wear plate requires the use of a wear-resistant steel quality. For this, le Proven steels that have high strength with good toughness and good wear properties when weldable even without preheating.

Nach dem Schweißen 'des Zungenauflagekastens wird die Gleitplatte zur Erzielung einer durchgehenden Auflage der Zunge spanabhebend bearbeitet. Bei der Montage der erfindungsgemäßen Zungenvorrichtung werden Backenschiene und Beischiene mit dem verwindungssteifen Zungenauflagekasten mit hochfesten Schrauben, die horizontal durch die Schienen und den Zungenauflagekasten gesteckt werden, verschraubt. Es wird dann die Zunge eingesetzt. Die Zungenbasis ist dabei dem Profil der Einsteckschiene angeglichen und mit dieser verschweißt. An die Stelle der Schweißverbindung kann auch ein verlaschter Schrägstoß treten.After welding the tongue support box, the slide plate is machined to achieve a continuous support of the tongue. When assembling the tongue device according to the invention, the stock rail and side rail are screwed to the torsion-resistant tongue support box with high-strength screws which are inserted horizontally through the rails and the tongue support box. The tongue is then inserted. The tongue base is matched to the profile of the insert rail and welded to it. A welded oblique joint can also take the place of the welded joint.

Zur Verschiebung der Zunge zwischen Backenschiene und Beischiene kann man sich einer üblichen Stellvorrichtung bedienen. Das Stellelement ist dabei mit einem Zapfen, der sich an der Unterseite der Zunge im Bereich der Zungenspitze befindet, verbunden. Eine bevorzugte Ausführungsfom der erfindungsgemäßen Zungenvorrichtung ist deshalb dadurch gekennzeichnet, daß der Zungenauflagekasten im Bereich des Zungenendes Ausschnitte zur Aufnahme des Zungenzapfens und zur Durchführung eines am Zungenzapfen angreifenden Zungenverstellelementes aufweist.A conventional adjusting device can be used to move the tongue between the stock rail and the side rail. The actuating element is connected to a pin which is located on the underside of the tongue in the area of the tongue tip. A preferred embodiment of the tongue device according to the invention is therefore characterized in that the tongue support box has cutouts in the area of the tongue end for receiving the tongue pin and for carrying out a tongue adjustment element engaging on the tongue pin.

Es ist zweckmäßig, daß unterhalb des Ausschnittes der Gleitplatte auch die Unterlagsplatte einen entsprechenden Ausschnitt aufweist, damit Wasser, die etwa Regenwasser, durch die Vorrichtung nach unten abgeführt werden kann.It is expedient that below the cutout of the slide plate the base plate also has a corresponding cutout so that water, such as rainwater, can be drained down through the device.

Um den Übergang der Leitkante der Einsteckschiene zur Leitkante der Beischiene ohne Sprung zu gewährleisten, ist eine bevorzugte Ausführungsform der Zungenvorrichtung so ausgebildet, daß die Beischiene eine Ausnehmung für die Leitschiene der Einsteckschiene aufweist.In order to ensure the transition of the leading edge of the insertion rail to the leading edge of the side rail without a jump, a preferred embodiment of the tongue device is designed such that the side rail has a recess for the guide rail of the insertion rail.

Zur weiteren Erhöhung der mechanischen Stabilität und damit der Betriebssicherheit kann der Zungenauflagekasten so ausgestaltet werden, daß die Zungenbasis an seiner der Beischiene zugewendeten Seite befestigbar ist. Eine solche bevorzugte Ausführungsfom der erfindungsgemäßen Zungenvorrichtung ist dadurch gekennzeichnet, daß der Zungenauflagekasten im Bereich der Zungenbasis sich bis zur Einsteckschiene erstreckt und an der der Beischiene zugewendeten Seite eine Ausklinkung aufweist, die in ihrer Abmessung der auf Schienenprofilhöhe ausgeführten Zungenbasis entspricht und wobei die Backenschiene mit dem Zungenauflagekasten im Bereich der Ausklinkung, der Zungenbasis, dem Futterstück und der Beischiene verschraubt ist. Hierduch wird die Lage der Zunge im Zungenbereich bestimmt. Von besonderem Vorteil ist dabei, daß das Zungenende hinter der Federstelle und vor der Schweißstelle von Zungenbasis und Einsteckschiene fest eingespannt ist. Die Gefahr von Rissen oder Brüchen im Bereich der Schweißstelle wird dadurch beseitigt.To further increase the mechanical stability and thus the operational safety, the tongue support box can be designed in such a way that the tongue base can be fastened on its side facing the side rail. Such a preferred embodiment of the tongue device according to the invention is characterized in that the tongue support box extends in the area of the tongue base as far as the insertion rail and on the side facing the side rail has a notch which corresponds in its dimension to the tongue base executed at the rail profile height and the cheek rail with the Tongue support box is screwed in the area of the notch, the tongue base, the lining piece and the side rail. This determines the position of the tongue in the area of the tongue. It is particularly advantageous that the tongue end is firmly clamped behind the spring point and in front of the welding point of the tongue base and insertion rail. This eliminates the risk of cracks or breaks in the area of the weld.

Die erfindungsgemäße Zungenvorrichtung weist somit eine Reihe von besonderen Vorteilen auf, die die Herstellung der Vorrichtung und/oder deren Betriebssicherheit betreffen :The tongue device according to the invention thus has a number of special advantages which relate to the manufacture of the device and / or its operational safety:

Die erfindungsgemäßse Zungenvorrichtung kann rationell mittels Schweißautomaten hergestellt werden. Es werden keine Sonderprofile benötigt. Es können vielmehr Standardprofile eingesetzt werden, so daß die Lagerhaltungskosten entsprechend gering sind. Durch die Verwendung von Stahlwerkstoffen mit weniger als 0,25 % Kohlenstoffgehalt kann auf die Vorwärmung beim Schweißen verzichtet werden. Die Montage wird wesentlich erleichtert, da nach der spanabhebenden Bearbeitung keine Schweißungen mehr vorzunehmen sind und damit ein Wärmeverzug der Bauteile ausgeschlossen ist. Die Zungenvorrichtung hat die gleiche Bauteile die Anschlußgleise. Es sind deshalb keine zusätzlichen baulichen Arbeiten für einen etwaigen Höhenausgleich notwendig. Die gesamte Vorrichtung stellt eine stabile, verwindungssteife Einheit dar, welche vorgefertigt am Ort des Einbaues zusammengesetzt werden kann. Die Gefahr von Brüchen, Rissen oder anderen Schädigungen, insbesondere im Zungenbereich, ist weitgehend beseitigt.The tongue device according to the invention can be efficiently produced by means of automatic welding machines. No special profiles are required. Rather, standard profiles can be used, so that the storage costs are correspondingly low. The use of steel materials with less than 0.25% carbon content means that preheating during welding can be dispensed with. The assembly is made considerably easier, since after the machining no welds have to be carried out and a heat distortion of the components is excluded. The tongue device has the same components as the sidings. There is therefore no need for any additional construction work for any height compensation. The entire device is a stable, torsionally rigid unit, which can be assembled prefabricated at the place of installation. The risk of breakage, tears or other damage, especially in the tongue area, has been largely eliminated.
