Abstract
Description
Die Erfindung betrifft ein Sicherungselement für einen Zungenkloben eines Klammerverschlusses für ein Weichenstellsystem.The invention relates to a securing element for a tongue block of a clip closure for a points system.
In einem Weichenstellsystem werden je nach vorgegebener Fahrrichtung zwei Stellzungen so bewegt, dass sich eine der beiden Stellzungen in Kontakt zur zugehörigen Backenschiene befindet, während sich die andere Stellzunge in einem geeigneten Abstand, dem sogenannten Zungenaufschlag, von der zugehörigen anderen Backenschiene entfernt befindet. Die gleichzeitige Steuerung der Weichenverschlüsse eines Weichenstellsystems geschieht über eine Schieberstange, die mit Verschlussklammern zusammenwirkt und den Weichenverschluss öffnet bzw. verriegelt. Bei einem vertikalen Klammerverschluss wird die Verschlussklammer um eine horizontale Achse an einem Zungenkloben verschwenkt. Der Zungenkloben ist zudem über eine Schraubbefestigung mit der Stellzunge verbunden. Um die einzelnen Komponenten eines wie oben beschriebenen Weichenstellsystems exakt justieren zu können, ist es im Stand der Technik bekannt, die Verschlussklammer über einen Exzenterbolzen am Zungenkloben schwenkbar zu befestigen. Die Verwendung eines Exzenterbolzens bedingt, dass über ein geeignetes Einstellelement, wie z.B. eine Einstellscheibe, der Hub des Exzenterbolzens in abgestuften Schritten eingestellt werden kann. Auch die genaue Position der Stellzunge relativ zum Zungenkloben ist einstellbar gestaltet. Damit die Komponenten während des Betriebs überprüft und gegebenenfalls nachjustiert werden können, müssen die Einstellkomponenten für Weichenschlösser leicht zugänglich sein. Dies bedingt allerdings, dass die Gefahr einer Verschmutzung gegeben ist. Weiterhin sind hohe Sicherheitsstandards zu erfüllen. Zu diesen gehört auch, dass sich die Einstell- und Befestigungskomponenten im Bereich Zungenklobens nicht selbsttätig lösen können. Aus diesem Grund wird eine Lösung gesucht, um die Betriebssicherheit des Weichenstellsystems zu erhöhen.In a point setting system, two setting tongues are moved, depending on the given direction of travel, such that one of the two setting tongues is in contact with the associated stock rail, while the other setting tongue is located at a suitable distance, the so-called tongue surcharge, from the associated other stock rail. The simultaneous control of the point locks of a points setting system is done via a slide rod, which cooperates with closing clips and opens and locks the points closure. In a vertical clip closure, the closure clip is pivoted about a horizontal axis on a tongue block. The tongue block is also connected via a screw with the Stellzunge. In order to be able to precisely adjust the individual components of a point adjustment system as described above, it is known in the prior art to use the closure clip via an eccentric pin on the tongue block pivotally attach. The use of an eccentric bolt requires that the stroke of the eccentric pin can be adjusted in graduated steps via a suitable adjustment element, such as a dial. The exact position of the positioning tongue relative to the tongue block is designed adjustable. In order for the components to be checked during operation and, if necessary, readjusted, the setting components for switch locks must be easily accessible. However, this requires that the risk of contamination is given. Furthermore, high safety standards must be met. One of these is that the adjustment and fastening components in the area of tongue clamps can not be released automatically. For this reason, a solution is sought to increase the reliability of the point setting system.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Sicherungselement für einen Zungenkloben eines Klammerverschlusses für ein Weichenstellsystem vorzuschlagen, das eine erhöhte Betriebssicherheit des Weichenstellsystems auch bei hoher mechanischer Belastung und sehr langer Einsatzzeit des Weichenstellsystems ermöglicht.The invention has for its object to provide a securing element for a tongue block of a staple closure for a point system, which allows increased reliability of the point system even at high mechanical load and very long time of use of point control system.
Diese Aufgabe wird durch ein Sicherungselement mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen folgen aus den übrigen Ansprüchen.This object is achieved by a securing element having the features of claim 1. Preferred embodiments follow from the remaining claims.
Das Sicherungselement für einen Zungenkloben eines Klammerverschlusses für ein Weichenstellsystem umfasst einen oberen Abdeckbereich mit einem Sicherungsabschnitt zur Sicherung gegen Herausdrehen der Zungenbefestigungsschraube zwischen Stellzunge und Zungenkloben, einen im Wesentlichen senkrecht zum oberen Abdeckbereich angeordneten, in Einbaulage im Wesentlichen vertikal orientierten, sowie einstückig mit dem oberen Abdeckbereich ausgebildeten seitlichen Abdeckbereich, und einen ersten Sicherungsbereich und einen zweiten Sicherungsbereich, die jeweils parallel zueinander angeordnet und einstückig mit dem seitlichen Abdeckbereich ausgebildet sind. Jeder Sicherungsbereich ist senkrecht zum seitlichen Abdeckbereich sowie zum oberen Abdeckbereich ausgerichtet und vom oberen Abdeckbereich beabstandet, und jeder Sicherungsbereich sichert eine Bolzenverbindung zur Befestigung einer Verschlussklammer am Zungenkloben gegen unbeabsichtigtes Lösen.The locking element for a tongue block of a clip closure for a points system comprises an upper cover portion with a securing portion for securing against unscrewing the tongue fastening screw between the positioning tab and tongue block, arranged substantially perpendicular to the upper cover, in the installed position substantially vertically oriented, and integrally with the upper cover formed side cover portion, and a first securing portion and a second securing portion, which are each arranged parallel to each other and formed integrally with the lateral cover portion. Each fuse portion is oriented perpendicular to the side cover portion and the upper cover portion and spaced from the upper cover portion, and each securing portion secures a bolt connection for attaching a locking bracket to the tongue block against accidental release.
Indem das Sicherungselement einen oberen Abdeckbereich, einen seitlichem Abdeckbereich und zwei Sicherungsbereiche aufweist, können die Einstellkomponenten am Zungenkloben, nämlich die Zungenbefestigungsschraube zur Befestigung der Stellzunge und die Bolzenverbindung zur Befestigung der Verschlussklammer gegen Herausfallen gesichert werden. Somit werden sämtliche kritischen Einzelkomponenten über das Sicherungselement nach der Erfindung geschützt. Da zusätzlich zu Sicherungselement noch separate Sicherheitsvorkehrungen zur Lagefixierung der Zungenbefestigungsschraube sowie des Bolzens zur Befestigung der Verschlussklammer vorgesehen sein können, wird die Betriebssicherheit des Weichenstellsystems erheblich erhöht. Das Sicherungselement hat diesbezüglich eine Doppelfunktion. Es stellt selbst aktiv eine Schutzfunktion für die Zungenbefestigungsschraube und den Verschlussklammerbolzen dar, erfüllt aber die zusätzliche Schutzfunktion, dass zusätzliche Sicherheitselemente ebenfalls lagefixiert werden können. Ein weiterer Vorteil des Sicherungselements ist die einfache Geometrie, die es nach einer bevorzugten Ausführungsform der Erfindung ermöglicht, das Sicherungselement aus einem flächigen Blechstanzteil herzustellen und durch Biegen in die gewünschte Form zu bringen.By having the securing member having an upper cover portion, a side cover portion, and two securing portions, the adjusting components on the tongue block, namely, the tongue fixing screw for fixing the adjusting tongue and the bolt connection for securing the locking clip, can be prevented from falling out. Thus, all critical individual components are protected by the fuse element according to the invention. Since, in addition to securing element, separate safety precautions for fixing the position of the tongue fastening screw and of the bolt for fastening the closing clip can be provided, the operational reliability of the point setting system is considerably increased. The fuse element has a double function in this regard. It is itself actively a protective function for the tongue fastening screw and the locking bolt, but fulfills the additional protective function that additional security elements can also be fixed in position. Another advantage of the fuse element is the simple geometry, which makes it possible according to a preferred embodiment of the invention to produce the fuse element from a flat sheet metal stamping and bring by bending in the desired shape.
Vorzugsweise besteht das Sicherungselement aus Federstahl, der hohe Härte, Festigkeit und Elastizität in sich vereint.Preferably, the securing element consists of spring steel, which combines high hardness, strength and elasticity in itself.
Nach einer bevorzugten Ausführungsform der Erfindung ist das Sicherungselement so dimensioniert und gestaltet, dass der erste Sicherungsbereich einen Exzenterbolzen zur Befestigung der Verschlussklammer am Zungenkloben gegen Herausfallen sichert. Zu diesem Zweck ist der erste Sicherungsbereich so gestaltet, dass der Exzenterbolzen an einer Axialbewegung entgegengesetzt zur Einführrichtung bei der Montage gehindert wird. Dies kann durch eine vollständige Abdeckung eines verbreiterten Kopfes des Exzenterbolzens erfolgen oder aber auch indem eine formschlüssige Verbindung mit einem anderen Element hergestellt wird, das wiederum formschlüssig mit dem Exzenterbolzen verbunden ist. Im konkreten Fall kann dies eine Einstellscheibe sein, die mit dem Kopf des Exzenterbolzens zusammen wirkt, um durch eine gezielte, abschnittsweise Drehung einen gewünschten Hub innerhalb des vorhandenen Verstellbereichs des Exzenterbolzens einzustellen.According to a preferred embodiment of the invention, the securing element is dimensioned and designed such that the first securing area secures an eccentric bolt for fastening the closing clip on the tongue block against falling out. For this purpose, the first securing portion is designed so that the eccentric pin is prevented from axial movement opposite to the insertion direction during assembly. This can be done by a complete coverage of a widened head of the eccentric bolt or even by a positive connection with another element is produced, which in turn is positively connected to the eccentric pin. In the specific case, this may be a dial, which cooperates with the head of the eccentric pin to set a desired stroke within the existing adjustment of the eccentric bolt by a targeted, sectionwise rotation.
Vorzugsweise ist das Sicherungselement so dimensioniert und gestaltet, dass der zweite Sicherungsbereich eine auf einen Exzenterbolzen zur Befestigung der Verschlussklammer am Zungenkloben fixierte Befestigungsmutter gegen Verdrehen sichert. Dies kann dadurch erfolgen, dass der zweite Sicherungsbereich mit einer sternförmigen Öffnung versehen ist, welche die Befestigungsmutter umgreift, so dass allenfalls eine Verdrehung der Befestigungsmutter in einem sehr engen und damit in Bezug auf das unbeabsichtigte Lösen des Exzenterbolzens ungefährlichen Winkelbereich erfolgen kann.Preferably, the securing element is dimensioned and designed such that the second securing region secures against rotation an attachment nut fixed on an eccentric bolt for fastening the closure clip to the tongue clamp. This can take place in that the second securing area is provided with a star-shaped opening, which surrounds the fastening nut, so that at most a rotation of the fastening nut in a very narrow and thus with respect to the unintentional release the eccentric bolt safe angle range can be done.
Nach einer bevorzugten Ausführungsform der Erfindung ist der obere Abdeckbereich dimensioniert, um einen Sicherungsring um den Kopf der Zungenbefestigungsschraube in vertikaler Richtung zu fixieren. Es ist somit bei dem Klammerverschluss ein zusätzlicher Sicherungsring um den Kopf der Zungenbefestigungsschraube vorgesehen, der über den oberen Abdeckbereich daran gehindert wird, in vertikaler Richtung aus dem Eingriff mit dem Kopf der Zungenbefestigungsschraube zu gelangen.According to a preferred embodiment of the invention, the upper cover portion is dimensioned to fix a retaining ring around the head of the tongue fastening screw in the vertical direction. Thus, in the clip fastener, there is provided an additional circlip around the head of the tongue-fixing screw, which is prevented from passing over the upper cover portion from engaging the head of the tongue-fixing screw in the vertical direction.
Vorzugsweise umfasst das Sicherungselement weiterhin eine Abdeckzunge im Bereich des oberen Abdeckbereichs, welche eine zur Verhinderung der Drehung des Sicherungsrings vorgesehene Fixierschraube gegen Herausfallen sichert. In Zusammenwirken mit der oben genannten Dimensionierung des oberen Abdeckbereichs, so dass der um den Kopf der Zungenbefestigungsschraube angeordnete Sicherungsring nicht in vertikaler Richtung aus dem Eingriff mit dem Kopf der Zungenbefestigungsschraube gelangen kann, lässt sich auf diese Weise eine vollständige Sicherung der Zungenbefestigungsschraube erreichen. Die Zungenbefestigungsschraube kann nicht in vertikaler Richtung aus dem Zungenkloben herausgedreht werden, da dies der obere Abdeckbereich des Sicherungselements verhindert. Die Zungenbefestigungsschraube kann auch nicht in nennenswertem Umfang gedreht werden, weil der Sicherungsring um den Kopf der Zungenbefestigungsschraube durch die Fixierschraube an einer Drehung gehindert wird. Außerdem kann der Sicherungsring nicht in vertikaler Richtung aus dem Eingriff mit dem Kopf der Zungenbefestigungsschraube kommen. Schließlich ist die Fixierschraube zur Fixierung des Sicherungsrings in Rotationsrichtung gegen ein Herausfallen in vertikaler Richtung durch die Abdeckzunge im Bereich des oberen Abdeckbereichs des Sicherungselements geschützt.Preferably, the securing element further comprises a covering tongue in the region of the upper covering area, which secures a fixing screw provided for preventing the rotation of the securing ring from falling out. In cooperation with the above-mentioned dimensioning of the upper cover area, so that the circlip arranged around the head of the tongue fixing screw can not come out of engagement with the head of the tongue fixing screw in the vertical direction, a complete securing of the tongue fixing screw can be achieved in this way. The tongue fixing screw can not be rotated out of the tongue block in the vertical direction, as this prevents the upper cover portion of the securing element. Also, the tongue fixing screw can not be turned to any appreciable extent because the locking ring around the head of the tongue fixing screw is prevented from rotating by the fixing screw. In addition, the locking ring can not come out of engagement with the head of the tongue fastening screw in the vertical direction. Finally, the fixing screw for fixing the securing ring in the direction of rotation is protected against falling out in the vertical direction by the covering tongue in the region of the upper covering area of the securing element.
Nach einer bevorzugten Ausführungsform der Erfindung umfasst das Sicherungselement weiterhin eine Öffnung im oberen Abdeckbereich, die dimensioniert und angeordnet ist, dass sich in Einbaulage ein vom Kopf der Zungenbefestigungsschraube nach oben ragender Zapfen durch die Öffnung erstreckt. Auf diese Weise wird das Sicherungselement auf eine besonders einfache Weise in der richtigen Lage gehalten.According to a preferred embodiment of the invention, the securing element further comprises an opening in the upper cover area, which is dimensioned and arranged so that in the installed position extends from the head of the tongue fastening screw upwardly projecting pin through the opening. In this way, the securing element is held in a particularly simple manner in the correct position.
