Die Erfindung betrifft eine Weiche umfassend Fahrschienen, Flügelschienen und ein Herzstück mit zwischen den Flügelschienen hin- und herbewegbarer Herzstückspitze, wobei die Fahrschienen und die Flügelschiene auf einer Schwelle befestigt sind, auf der eine Stelleinrichtung zum Verstellen der Herzstückspitze angeordnet ist, die über wenigstens eine Leitung mit einer Antriebseinrichtung verbunden ist.The invention relates to a switch comprising travel rails, wing rails and a frog with the frog point reciprocable between the wing rails, wherein the rails and the wing rail are mounted on a threshold on which an adjusting device for adjusting the frog point is arranged, which via at least one line is connected to a drive device.
Um Zungenschienen relativ zu Fahrschienen zwischen einer Anlageposition und einer Ablageposition zu verstellen, sind Stelleinrichtungen erforderlich, die über ein Verbindungsgestänge mit den Zungenschienen verbunden sind. Stelleinrichtungen sind auch bei Weichen mit einem Herzstück mit beweglicher Herzstückspitze für die Umstellung der Herzstückspitze zwischen den beiden Flügelschienen erforderlich. In beiden Fällen sind die Stelleinrichtung sowie das Verbindungsgestänge in der Regel zwischen zwei Schwellen, d.h. im sogenannten Schwellenfach oder in einer Hohltrogschwelle angeordnet, in der sich auch eine Antriebsvorrichtung, wie z.B. ein Hydraulikantrieb, befinden kann. Die Anordnung einer Stelleinrichtung für eine bewegliche Herzstückspitze samt Verbindungsgestänge im Schwellenfach bzw. in einer Trogschwelle ist beispielsweise in der
Nachteilig ist hierbei, dass Trogschwellen spezielle Vorkehrungen im Bereich des Schottereinbaus erfordern, da Trogschwellen im Allgemeinen tiefer eingesetzt werden müssen als Standardschwellen. Folglich ist eine gesonderte Auskofferung des Schotterplanums an der Einbaustelle erforderlich.The disadvantage here is that trough sleepers require special provisions in the field of bulkhead installation, since trough sleepers must generally be used deeper than standard sleepers. Consequently, a separate Ausköseung the ballast at the installation site is required.
Bei der aus der
Die vorliegende Erfindung zielt nun darauf ab, die in der
Zur Lösung dieser Aufgabe ist die Weiche der eingangs genannten Art erfindungsgemäß derart weitergebildet, dass die Schwelle eine Betonschwelle quaderförmiger Geometrie mit einer Oberseite, die Oberseite begrenzenden, abgeschrägten Längsrändern und von den Längsrändern ausgehenden Seitenflächen ist, dass die Stelleinrichtung an der Oberseite der Schwelle zwischen einer Fahrschiene und einer Flügelschiene befestigt ist, dass die Antriebseinrichtung außerhalb der Fahrschienen angeordnet und vorzugsweise mit der Schwelle verbunden ist, dass die wenigstens eine die Antriebseinrichtung mit der Stelleinrichtung verbindende Leitung entlang der abgeschrägten Längsränder verläuft, wobei die Stelleinrichtung, die wenigstens eine Leitung und ggf. die Antriebseinrichtung innerhalb der Schwellenbreite verlaufen.To solve this problem, the switch of the type mentioned is inventively developed such that the threshold is a concrete sleeper cuboid geometry with an upper side, the top limiting beveled longitudinal edges and outgoing from the longitudinal edges side surfaces, that the actuating device at the top of the threshold between a Ride rail and a wing rail is fixed, that the drive device is arranged outside the rails and preferably connected to the threshold that the at least one connecting the drive device with the actuator line along the slanted longitudinal edges, wherein the adjusting device, the at least one line and possibly the drive device extend within the threshold width.
Erfindungsgemäß wird somit eine übliche Betonschwelle, insbesondere eine Normbetonschwelle zum Befestigen der Antriebs- und Stelleinrichtungen verwendet, wobei die zum Betätigen der beweglichen Herzstückspitze benötigten Bauelemente innerhalb der Schwellenbreite, d.h. insbesondere innerhalb einer Umhüllenden verlaufen, die seitlich von den Betonschwellen-Seitenflächen bzw. deren Verlängerungen begrenzt ist. Somit stehen keine Elemente seitlich über die Schwelle vor, so dass ein Stopfen im Weichenbereich gleichermaßen wie im Gleis selbst erfolgen kann.According to the invention, therefore, a conventional concrete sleeper, in particular a standard concrete sleeper, is used for fastening the drive and adjusting devices, wherein the components required for actuating the movable frog tip extend within the threshold width, ie in particular within an envelope, laterally from the concrete sleeper side surfaces or their extensions is limited. Thus, no elements are present laterally beyond the threshold, so that a plug in the switch area can be done equally as in the track itself.
Ferner ergibt sich der Vorteil, dass der Aufbau homogen ist, d.h. die Schwellen bleiben durchgehend im Weichenbereich baugleich, unabhängig davon, ob ein Antrieb für ein bewegliches Herzstück vorgesehen ist oder nicht. Die Anordnung der Stelleinrichtung, der wenigstens einen Leitung und ggf. der Antriebseinrichtung innerhalb der Schwellenbreite bedeutet hierbei bevorzugt, dass die genannten Baueinheiten in der Normalprojektion nicht über das breiteste Maß der Schwelle vorstehen.Furthermore, there is the advantage that the construction is homogeneous, i. the sleepers stay the same throughout the turnout area, regardless of whether a drive for a moving centerpiece is provided or not. The arrangement of the adjusting device, the at least one line and possibly the drive device within the threshold width here means preferably that the units in the normal projection do not protrude over the widest measure of the threshold.
Die Erfindung ermöglicht einen einfachen Einbau der Weiche, da keine speziellen Vorkehrungen im Bereich des Schottereinbaus notwendig sind, wie dies bei Stahltrogschwellen der Fall ist, die grundsätzlich tiefer als Standardschwellen eingesetzt werden müssen. Weiters ergeben sich identische Schienenlagerungen und Schienenbefestigungen wie bei Schwellen, die keinen Weichenantrieb aufweisen.The invention allows a simple installation of the switch, as no special precautions in the field of bulkhead installation are necessary, as is the case with steel trough sleepers, which must be used in principle deeper than standard sleepers. Furthermore, there are identical rail bearings and rail fastenings as in sleepers that have no points drive.
Die insbesondere als Hydraulikeinheit ausgebildete Antriebseinrichtung ist vorzugsweise in einem Endbereich der Schwelle außerhalb der Fahrschienen mit der Betonschwelle verbunden, wobei ggf. eine Halterung von der Schwelle ausgehen kann, die sich über die Stirnseite der Betonschwelle hinaus erstreckt, um somit hinreichend Platz zum Befestigen der Antriebseinrichtung zur Verfügung stellen zu können. Unabhängig hiervon ist jedoch die Breitenerstreckung der Halterung und der Antriebseinrichtung bevorzugt so gewählt, dass diese sich grundsätzlich innerhalb der Breite der Betonschwelle befinden. Dabei ist die Aufbauhöhe sowohl der Stelleinrichtung als auch der Antriebseinrichtung bevorzugt so gewählt, dass eine Kollision mit dem Lichtraumprofil ausgeschlossen ist.The drive device, which is designed in particular as a hydraulic unit, is preferably connected to the concrete sleeper in an end region of the sleeper outside the rails, wherein a bracket may extend from the sleeper that extends beyond the front side of the concrete sleeper, thus providing sufficient space for securing the drive device to make available. Regardless of this, however, the width extension of the holder and the drive device is preferably selected so that they are basically within the width of the concrete sleeper. In this case, the assembly height of both the adjusting device and the drive device is preferably selected so that a collision with the clearance gauge is excluded.
Wenn, wie dies einer bevorzugten Ausbildung entspricht, die Antriebseinrichtung als Hydraulikeinheit ausgebildet ist, ist diese über die wenigstens eine als Hydraulikleitung ausgebildete Leitung mit der Stelleinrichtung hydraulisch verbunden.If, as corresponds to a preferred embodiment, the drive device is designed as a hydraulic unit, is this is hydraulically connected via the at least one designed as a hydraulic line line with the actuator.
In vorteilhafter Weise sind die Hydraulikleitungen und erfindungsgemäß das die Stelleinrichtung und die bewegliche Herzstückspitze verbindende Verbindungsgestänge innerhalb der Breite der Betonschwelle angeordnet. Das von der Stelleinrichtung ausgehende Verbindungsgestänge umfasst neben einer für die Umstellung der beweglichen Herzstückspitze verantwortlichen Stellstange ggf. auch eine Prüferstange für eine Endlagenprüfeinrichtung. Um die Anordnung des Verbindungsgestänges innerhalb der Schwellenbreite in einfacher Weise zu bewerkstelligen, sind die Stellstange und ggf. die Prüferstange erfindungsgemäß unterhalb des Schienenfußes einer Flügelschiene hindurchgeführt. Insbesondere kann in diesem Zusammenhang vorgesehen sein, dass die Flügelschiene mit einer gegenüber der Herzstückspitze verringerten Höhe ausgebildet ist und dass die Stellstange und ggf. die Prüferstange durch einen Freiraum zwischen dem Schienenfuß der Flügelschiene und der Oberseite der Schwelle hindurchgeführt sind. Die Stellstange und ggf. die Prüferstange können hierbei gerade ausgeführt sein, d.h. ohne Verkröpfung, so dass sich ein optimaler Kraftfluss ergibt. Dabei greifen die Stellstange und ggf. die Prüferstange bevorzugt am Schienenfuß der Herzstückspitze an.Advantageously, the hydraulic lines and according to the invention the connection linkage connecting the setting device and the movable frog tip are arranged within the width of the concrete sleeper. If necessary, the connection linkage emanating from the setting device also comprises, in addition to a control rod responsible for the changeover of the movable frog tip, also a checker rod for an end position test device. In order to accomplish the arrangement of the connecting linkage within the threshold width in a simple manner, the control rod and possibly the Prüferstange are inventively passed below the rail foot of a wing rail. In particular, it can be provided in this context that the wing rail is formed with a reduced height relative to the frog tip and that the control rod and possibly the Prüferstange are passed through a space between the rail of the wing rail and the top of the threshold. The control rod and possibly the Prüferstange can be made straight here, i. without cranking, resulting in an optimal power flow. In this case, the adjusting rod and optionally the Prüferstange preferably engage the rail of the frog tip.
Damit Relativverschiebungen der beweglichen Herzstückspitze relativ zur die Stelleinrichtung tragenden Schwelle nicht zur Einleitung unerwünschter Kräfte auf die Stellstange und die Stelleinrichtung führen, sieht eine bevorzugte Ausbildung vor, dass die Stellstange und ggf. die Prüferstange jeweils über einen eine wenigstens zweiachsige Schwenkbewegung erlaubenden Schwenkmechanismus, insbesondere ein Kugelgelenk, an der Stelleinrichtung angelenkt sind. Zudem ist erfindungsgemäß vorgesehen, dass die Stellstange und ggf. die Prüferstange jeweils um eine vertikale Schwenkachse schwenkbar am Schienenfuß der beweglichen Herzstückspitze angelenkt sind.In order that relative displacements of the movable frog point relative to the actuating device carrying threshold do not lead to the initiation of undesirable forces on the control rod and the actuator, provides a preferred embodiment that the control rod and possibly the Prüferstange each have a at least two-axis pivoting movement permitting swivel mechanism, in particular Ball joint, are hinged to the adjusting device. In addition, the invention provides that the control rod and possibly the Prüferstange are each articulated about a vertical pivot axis pivotally mounted on the rail of the movable frog tip.
Die Verbindung des Gestänges mit der Herzstückspitze erfolgt konstruktiv in besonders einfacher Weise dadurch, dass die Stellstange und ggf. die Prüferstange über einen den Schienenfuß umgreifenden Gabelkopf an der beweglichen Herzstückspitze angreifen.The connection of the linkage with the frog point is structurally in a particularly simple manner in that the control rod and possibly the Prüferstange attack over a rail foot engaging around the clevis on the movable frog point.
Eine verbesserte Stabilität der Herzstückspitze wird bevorzugt dadurch sichergestellt, dass die Flügelschienen mit einem asymmetrischen Zungenschienenprofil ausgebildet sind.An improved stability of the frog point is preferably ensured by the fact that the wing rails are formed with an asymmetric tongue rail profile.
Bevorzugt liegen die Stelleinrichtung, die Flügelschienen und die Herzstückspitze nicht unmittelbar auf der Betonschwelle auf, sondern auf einer Grundplatte, die ggf. unter Zwischenschaltung einer elastischen Unterlagsplatte auf der Betonschwelle angeordnet ist. Insbesondere die bewegliche Herzstückspitze ist an der auf der Schwelle angeordneten Grundplatte gleitend gelagert, sodass diese Grundplatte als Gleitstuhl für die Herzstückspitze fungiert.Preferably, the adjusting device, the wing rails and the frog point are not directly on the concrete sleeper, but on a base plate, which is optionally arranged with the interposition of an elastic base plate on the concrete sleeper. In particular, the movable frog point is slidably mounted on the arranged on the threshold base plate, so that this base plate acts as a sliding chair for the frog point.
Die Grundplatte ist bevorzugt über wenigstens ein in eine Aussparung der Betonschwelle einschraubbares Befestigungselement mit der Betonschwelle verbunden, wobei die Stelleinrichtung mit der Betonschwelle über das wenigstens eine Befestigungselement verbunden ist. Dies schließt jedoch nicht aus, dass weitere Befestigungselemente vorgesehen sind, die ggf. in gesondert einzubringende Bohrungen einschraubbar sind, die von der Oberseite der Betonschwelle ausgehen. Es kann folglich die Stelleinrichtung nicht nur ohne Änderung der Betonschwellenform mit dieser verbunden werden, sondern zusätzlich können bereits vorhandene Bohrungen in der Betonschwelle benutzt werden, um die Stelleinrichtung zu befestigen.The base plate is preferably connected via at least one screwed into a recess of the concrete sleeper fastener with the concrete sleeper, wherein the adjusting device is connected to the concrete sleeper on the at least one fastener. However, this does not exclude that further fasteners are provided, which may be screwed into separately introduced holes that emanate from the top of the concrete sleeper. Consequently, the adjusting device can not only be connected to it without changing the concrete sleeper shape, but additionally already existing ones can be connected to it Holes in the concrete sleeper are used to secure the actuator.
Der bevorzugt vorgesehene Freiraum zwischen der Betonschwelle und der Unterseite des Schienenfußes der Flügelschienen wird in konstruktiv vorteilhafter und platzsparender Weise dadurch erzielt, dass an der Grundplatte ein Schienenstuhl zur Abstützung der Flügelschienen befestigt, insbesondere angeschweißt ist. Die Breite des Schienenstuhls entspricht bevorzugt höchstens der halben Breite der Schwelle, sodass die Stellstange und ggf. die Prüferstange seitlich des Schienenstuhls vorbeigeführt werden können.The preferably provided free space between the concrete sleeper and the underside of the rail foot of the wing rails is achieved in a structurally advantageous and space-saving manner, that attached to the base plate, a rail chair for supporting the wing rails, in particular welded. The width of the rail chair preferably corresponds to at most half the width of the threshold, so that the control rod and possibly the Prüferstange can be guided laterally of the rail chair.
Am Schienenstuhl greifen bevorzugt Mittel zum Niederspannen und zur seitlichen Abstützung der Flügelschienen an.On rail chair preferably resort to means for low voltage and lateral support of the wing rails.

Zwischen einer Flügelschiene 3 und einer Fahrschiene 2 ist an der Oberseite der Schwelle 5 eine Stelleinrichtung 11 befestigt, die über Leitungen 12 mit der Antriebseinrichtung 7 hydraulisch verbunden ist. In der Stelleinrichtung 11 wird der von der Antriebseinheit 7 zur Verfügung gestellte Hydraulikdruck beispielsweise mit Hilfe eines hydraulischen Zylinderkolbenaggregates in eine Stellbewegung in Richtung des Doppelpfeils 13 umgesetzt. Von der Stelleinrichtung 11 geht eine Stellstange 15 aus, die am Schienenfuß des beweglichen Herzstücks 4 angreift, um das bewegliche Herzstück 4 in Richtung des Doppelpfeils 13 hin und her bewegen zu können. Die Stelleinrichtung 11 kann neben dem weichenantrieb eine in diese integrierte weichenverschlusseinrichtung sowie eine gesonderte Endlagenprüfeinrichtung aufweisen. Der Weichenverschluss dient hierbei der Fixierung der beweglichen Herzstückspitze 4 in ihrer jeweiligen Endlage. Die Endlagenprüfeinrichtung dient dazu, den aktuellen Zustand der beweglichen Herzstückspitze 4 mechanisch abzutasten und ein Prüfsignal zu erzeugen, anhand dessen zuverlässig festgestellt werden kann, ob die bewegliche Herzstückspitze 4 korrekt umgestellt wurde und ob sich die bewegliche Herzstückspitze 4 in ihrer jeweiligen korrekten Endlage befindet. Die Endlagenprüfeinrichtung weist zu diesem Zweck eine Prüferstange 14 auf, welche sich im Wesentlichen quer zur Schienenlängsrichtung erstreckt und welche beim Umstellen des beweglichen Herzstücks 4 in Längsrichtung der Stange verschoben wird. Die Position der Prüferstange 14 wird in der Stelleinrichtung 11 mit Hilfe von elektromechanischen Wandlern erfasst, beispielsweise in der Form von Endschaltern oder Zungenprüfkontakten.Between a
