Description

Die Erfindung betrifft ein Weichenstellsystem gemäß dem Oberbegriff des Anspruches 1. Ein Weichenstell system weist typischerweise einen Weichenantrieb, Stellelemente, Verschlussvorrichtungen und Weichenzungen auf. Die beiden Weichenzungen werden von dem Weichenantrieb zwischen zwei Anschlägen bewegt. Dabei ist der Weichenantrieb seitlich vom Gleisbett angeordnet (EP 0 856 608 A1). Nachteilig bei dieser bekannten Vorrichtung ist vor Allem der erhebliche Platzbedarf für den Weichenantrieb, wodurch eine seitlich weit ausladende Bauform bedingt ist. An vielen Montageorten, beispielsweise innerhalb von Tunnelanlagen, fehlt dieser Platz jedoch häufig. Außerdem besteht aufgrund des seitlichen Anbaus des Weichenantriebes nicht die Möglichkeit einer kompletten Montage des gesamten Weichenstellsystems im Weichenwerk. Wenn der Weichenantrieb mit Verschlussvorrichtungen, die überwiegend auf Holzschwellen montiert werden, kombiniert wird, sind die Stellelemente im Schwellenfeld angeordnet, wodurch ein automatisches Stopfen der Weiche nicht möglich ist.The invention relates to a point system according to the preamble of claim 1. A point system typically has a point machine, actuators, locking devices and switch tongues. The two switch tongues are moved between two stops by the point machine. The point machine is located on the side of the track bed (EP 0 856 608 A1). A disadvantage of this known Above all, the device requires considerable space Point machine, which gives it a wide, projecting design is conditional. At many assembly locations, for example within of tunnel systems, this space is often missing. Moreover exists due to the side installation of the point machine not the possibility of a complete assembly of the whole Point setting system in the point plant. If the point machine with locking devices, mainly on wooden sleepers assembled, combined, are the control elements arranged in the threshold field, which causes automatic tamping the switch is not possible.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und ein Weichenstellsystem der gattungsgemäßen Art anzugeben, das bei geringerem Platzbedarf eine Komplettmontage im Weichenwerk und eine automatische Stopfbarkeit der Weiche und damit letztlich eine Verbesserung der Fahrdynamik gestattet.The object of the invention is to overcome these disadvantages eliminate and a switch system of the generic type to indicate that a complete assembly with less space in the turnout and automatic stuffing of the turnout and ultimately an improvement in driving dynamics allowed.

Die Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Durch die mittige Anordnung des Weichenantriebs zwischen den Schienen entfällt die seitliche Ausladung des Gesamtsystems. Probleme bei beengten Platzverhältnissen, die sich besonders auf die Montage auswirken, werden dadurch vermieden. Vereinfachungen ergeben sich beispielsweise bei der Weichenmontage in U-Bahn-Tunneln.The task is carried out with the characterizing features of the claim 1 solved. Due to the central arrangement of the point machine there is no lateral overhang between the rails of the overall system. Problems with limited space, that have a particular effect on the assembly avoided. Simplifications result, for example, from the assembly of switches in underground tunnels.

Der Weichenantrieb ist mit einer translatorisch verschiebbaren Stellstange ausgestaltet, die den Antrieb beidseitig durchsetzt und im Zusammenwirken mit den weiteren Stellelementen und Verschlussvorrichtungen zur Verschiebung der Weichenzungen relativ zu den Schienen dient. Die Stellstange des Antriebes ist dabei zwischen zwei Anschlägen bewegbar. Der Hub ist derart ausgelegt, dass entweder die eine Weichenzunge an der zugeordneten Schiene anliegt oder die andere Weichenzunge an der anderen Schiene. Führungselemente für die Stellstange können den gesamten Block des Weichenantriebes durchsetzen. Die beidseitig vorragenden Teile der Stellstange müssen nicht viel länger sein als der zu bewältigende Hub. Dadurch ergibt sich eine sehr präzise und wenig störanfällige Montageposition der Stellstange. Bei seitlicher Montage des Weichenantriebes ist die freie Länge der Stellstange sehr viel größer, womit insbesondere Justierprobleme und Stabilitätsprobleme verbunden sein können.The point machine is translationally movable Adjusting rod designed, the drive on both sides enforced and in cooperation with the other control elements and locking devices for moving the switch tongues serves relative to the rails. The control rod of the The drive can be moved between two stops. The Hub is designed so that either the switch tongue abuts the associated rail or the other switch tongue on the other rail. Guide elements for the control rod can enforce the entire block of the point machine. The protruding parts of the control rod on both sides do not have to be much longer than the stroke to be mastered. This results in a very precise and less prone to failure Mounting position of the control rod. When installing the Point machine is the free length of the control rod very much larger, with particular adjustment problems and stability problems can be connected.

Gemäß Anspruch 2 sind die Verschlussvorrichtungen als Außenverschlüsse ausgebildet. Im Zusammenwirken mit dem mittigen Weichenantrieb ergeben sich damit zwischen den Schienen keine zu beengten Platzverhältnisse.According to claim 2, the closure devices are as external closures educated. In cooperation with the middle There is therefore no point drive between the rails to limited space.

Bei einer vorteilhaften, in Anspruch 3 charakterisierten Ausführungsform ist vorgesehen, dass die Stellelemente innerhalb einer Hohlschwelle angeordnet sind. Weichen sind durch Witterungseinflüsse und durch das Befahren durch Züge einer hohen Beanspruchung ausgesetzt. Um diese möglichst gering zu halten, sind Hohlschwellen für die Unterbringung möglichst vieler Weichenkomponenten, beispielsweise auch von Endlagenprüfern, wie in Anspruch 4 angegeben, besonders geeignet. Eine mit Weichenkomponenten versehene Hohlschwelle kann wie konventionelle Eisenbahnschwellen als Stützelement unter dem Gleis angeordnet werden. Allfällige Gleisarbeiten werden somit nicht behindert.In an advantageous embodiment characterized in claim 3 it is provided that the control elements within a hollow threshold are arranged. Turnouts are due to weather influences and by driving through trains of a high one Exposed to stress. To keep this as low as possible, are hollow sleepers for the accommodation of as many as possible Switch components, for example also from end position testers, as indicated in claim 4, particularly suitable. A Hollow sleepers with switch components can be used like conventional ones Railway sleepers as a support element under the Track can be arranged. Any track work will be not disabled.

Das Gesamtkonzept für das beanspruchte Weichenstellsystem hat darüber hinaus den Vorteil, dass eine Komplettmontage im Weichenwerk möglich ist. Durch die Anordnung der Stellelemente innerhalb der Hohlschwelle ist außerdem das automatische Stopfen der Weiche realisierbar.The overall concept for the claimed switch system has furthermore the advantage that a complete assembly in the switch plant is possible. The arrangement of the control elements within the hollow threshold is also the automatic one The turnout can be plugged.

Die Erfindung wird nachfolgend anhand eines figürlich dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with reference to a figure Embodiment explained in more detail.

Die Figur zeigt ein Weichenstellsystem in Seitenansicht und in Draufsicht.The figure shows a turnout system in side view and in top view.

Das Weichenstell system besteht im Wesentlichen aus einem zwischen den Eisenbahnschienen 1 angeordnetem Weichenantrieb 2, von diesem betätigten Stellelementen 3 und Außenverschlüssen 4, die mit Weichenzungen 5 zusammenwirken. Die Stellelemente 3 und wenigstens ein Teil des Weichenantriebes 2 sind innerhalb einer Hohlschwelle 6 angeordnet. Der Weichenantrieb 2 besitzt einen doppelseitigen Stellschieber 7, welcher ein separates Betätigen beider Außenverschlüsse 4 ermöglicht. Die Verbindung zwischen dem Stellschieber 7 und abgewinkelten Antriebshebeln 8 der Außenverschlüsse 4 übernehmen spezielle Stellstangen 9, welche über seitliche Führungsbleche 10 geführt werden. Die Breite der Hohlschwelle 6 beträgt wie die Breite der Massivschwellen 300 mm. Diese Breite ist ausreichend für die Aufnahme der Stellelemente 3 und von Endlagenprüfvorrichtungen. Bei der üblichen Spurbreite von 1435 mm wird bei mittiger Anordnung des Weichenantriebes die maximale Schwellenlänge von 2600 mm nicht überschritten.The point system essentially consists of an intermediate the railroad tracks 1 arranged switch machine 2, of this actuated actuators 3 and external closures 4, which cooperate with switch tongues 5. The control elements 3 and at least part of the point machine 2 are inside a hollow threshold 6 arranged. The point machine 2 has a double-sided slide valve 7, which is a separate Operating both outer locks 4 allows. The Connection between the adjusting slide 7 and angled drive levers 8 of the outer closures 4 take over special Adjusting rods 9, which are guided over lateral guide plates 10 become. The width of the hollow sleeper 6 is like that Width of the solid sleepers 300 mm. This width is sufficient for the accommodation of the control elements 3 and end position test devices. With the usual track width of 1435 mm is the maximum with a central arrangement of the point machine Threshold length of 2600 mm not exceeded.

Die Erfindung beschränkt sich nicht auf das vorstehend angegebene Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen.The invention is not limited to the above Embodiment. Rather, there are a number of variations conceivable, which is also fundamentally different Execution make use of the features of the invention.
