Description

Die Erfindung bezieht sich auf eine Einrichtung zum Unterstützen der Umstellbewegung von Zungenschienen einer Weiche mit an einem gegen die Kraft einer Feder schwenkbaren Hebel gelagerten Rollen, welche die Zungenschienen über wenigstens einen Teil ihrer Umstellbewegung untergreifen.The invention relates to a device for supporting the Umstellbewegung of tongue rails of a switch with mounted on a pivotable against the force of a spring lever rollers which engage under the tongue rails over at least part of their Umstellbewegung.

Einrichtungen der eingangs genannten Art sind beispielsweise der EP 1055778 A2 zu entnehmen. Bei dieser bekannten Einrichtung werden die Zungenschienen während des Umstellvorgangs über federnd gegen die Unterseite des Schienenfußes gedrückte Rollen abgestützt. Bei der bekannten Ausbildung wurde in wenigstens einer Endlage der Umstellbewegung ein seitliches Abstützen durch eine Rolle erzielt. Die bekannte Einrichtung wurde zu diesem Zweck entsprechend justiert und verfügte über eine einstellbare Feder, wobei die gesamte Einrichtung zwischen den Schwellen mit einer den Schienenfuß der Backenschiene umgreifenden Zwinge bzw. Klemme festgelegt wurde. Auch die EP 692570 Al zeigt eine schwenkbare Lagerung für Rollen, welche über Federn an einem den Schienenfuß untergreifenden Basisteil festgelegt sind. Auch die dort vorgeschlagene Feder, welche als Tellerfeder und Zugfeder ausgebildet war, verfügte über eine Ein-stellbarkeit, wobei neben dem Umstand, dass diese Einrichtung wiederum nur zwischen den Schwellen angeordnet werden konnte, um Platz für das erforderliche Federpaket zu schaffen, hier auch noch die Gefahr bestand, dass durch zu festes Vorspannen der Feder ein weiterer Federweg behindert wird. Einrichtungen, welche prinzipiell nur zwischen den Schwellen angeordnet werden können, weisen generell den Nachteil auf, dass sie bei Wartungsarbeiten und insbesondere bei Gleisstopfarbeiten von den hierfür vorgesehenen Maschinen beschädigt oder zerstört werden können. Analoge Überlegungen gelten für den Gegenstand des deutschen Gebrauchsmusters DE 29605513 U1 und den Gegenstand der WO 94/28246 .Devices of the type mentioned are, for example, the EP 1055778 A2 refer to. In this known device, the tongue rails are supported during the Umstellvorgangs via resiliently pressed against the underside of the rail foot rollers. In the known training a lateral support was achieved by a roller in at least one end position of the Umstellbewegung. The known device was adjusted accordingly for this purpose and had an adjustable spring, the entire device between the thresholds was set with a rail foot of the stock rail encompassing ferrule or clamp. Also the EP 692570 Al shows a pivotal mounting for roles, which are defined by springs on a foot engaging under the base part. The proposed there spring, which was designed as a plate spring and tension spring, had a Ein-stellbarkeit, in addition to the fact that this device could again be arranged only between the thresholds to make room for the required spring assembly, here too there was a risk that an additional spring travel would be hindered by over-tightening the spring. Devices which in principle can only be arranged between the sleepers generally have the disadvantage that they can be damaged or destroyed by the machines provided for this purpose during maintenance work and, in particular, during tamping work. Similar considerations apply to the subject matter of the German utility model DE 29605513 U1 and the subject of the WO 94/28246 ,

Eine Einrichtung der eingangs genannten Art ist weiters aus der BE-A-1015216 zu entnehmen.A device of the type mentioned is further from the BE-A-1015216 refer to.

Die Erfindung zielt nun darauf ab, eine besonders kleinbauende Einrichtung zu schaffen, welche ohne Justierarbeit für eine Feder eingebaut werden kann und an unterschiedlichen Stellen für unterschiedliche Zwecke im Zuge der Unterstützung der Umstellbewegung von Zungenschienen zum Einsatz gelangen kann. Gleichzeitig zielt die Erfindung darauf ab, die Ausbildung hinreichend klein bauen zu können, um eine Anordnung der federnd gelagerten Rollen innerhalb des Profils von Schwellen an der Oberseite der Schwelle zu ermöglichen, sodass der Raum zwischen den Schwellen für Wartungsarbeiten und Gleisstopfarbeiten völlig freigehalten werden kann.The invention now aims to provide a particularly small-sized device which can be installed without adjustment work for a spring and can be used at different points for different purposes in the course of supporting the Umstellbewegung of tongue rails used. At the same time, the invention aims to be able to build the training sufficiently small to allow an arrangement of the spring-loaded rollers within the profile of sleepers at the top of the threshold, so that the space between the sleepers for maintenance work and track tamping work can be completely kept free.

Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Einrichtung im wesentlichen darin, dass der schwenkbare Hebel in einem Rahmen oder Kasten gelagert ist, dass Mittel zum Festlegen des Rahmens oder Kastens an einer Schwelle und/oder einer Rippenplatte vorgesehen sind, mit welchen der Rahmen oder Kasten auf der Oberfläche einer Schwelle bzw. einer Rippenplatte seitlich außerhalb eines Gleitstuhls festgelegt ist und dass die Feder im Abstand von der Schwenkachse des schwenkbaren Hebels zwischen der Schwellenoberseite und dem Hebel angeordnet ist. Dadurch, dass ein einfacher Rahmen oder Kasten vorgesehen ist, in welchem ein Hebel schwenkbar angelenkt ist und die für die federnde Abstützung der am Hebel festgelegten Rollen vorgesehene Feder einfach zwischen der Schwellenoberfläche und dem Hebel angeordnet wird, ergibt sich eine besonders kompakte Bauweise, bei welcher lediglich die Feder auf die Oberseite einer schwelle oder einer Rippenplatte aufgelegt werden muss und der Rahmen bzw. Kasten auf diese Feder aufgesetzt werden muss. Der Zusammenbau gestaltet sich somit ohne weitere Justierarbeiten überaus einfach, wobei die Bauweise hinreichend klein gehalten werden kann, um den Bereich zwischen den Schwellen freizuhalten, und lediglich mit dem Platz an der Oberfläche einer Schwelle das Auslangen gefunden werden kann. Gleichzeitig erlaubt es die erfindungsgemäße Ausbildung, eine derartige federnde Abstützung nachträglich ohne zusätzliche Modifikation anzubringen, wobei eine besonders einfache Ausgestaltung eines derartigen Kastens oder Rahmens dem österreichischen Gebrauchsmuster AT-GM 108/2006 entnommen werden kann.To achieve this object, the device according to the invention essentially consists in that the pivotable lever is mounted in a frame or box, that means for fixing the frame or box are provided at a threshold and / or a ribbed plate with which the frame or box the surface of a threshold or a ribbed plate is fixed laterally outside a Gleitstuhls and that the spring is arranged at a distance from the pivot axis of the pivotable lever between the threshold top and the lever. The fact that a simple frame or box is provided, in which a lever is pivotally mounted and provided for the resilient support of the rollers fixed to the lever spring is simply placed between the threshold surface and the lever, results in a particularly compact design, in which only the spring on the top of a threshold or a ribbed plate must be placed and the frame or box must be placed on this spring. The assembly is thus very simple without further adjustments, the design can be kept sufficiently small to keep the area between the thresholds, and only with the space on the surface of a threshold the end can be found. At the same time, the inventive design allows to mount such a resilient support subsequently without additional modification, with a particularly simple embodiment of such a box or From the Austrian utility model AT-GM 108/2006.

Da im vorliegenden Fall die Feder lediglich aufgelegt werden muss und eine nachträgliche Justierung durch Anziehen der Feder bzw. Kompression der Feder mittels eines Werkzeugs nicht erforderlich ist, kann in einfacher Weise sichergestellt werden, dass immer ein entsprechender Federweg zur Verfügung steht, wobei zu diesem Zweck die Ausbildung mit Vorteil so getroffen ist, dass der Hebel mit einem Anschlag des Rahmens oder Kastens zusammenwirkt, wobei die Feder teilweise entspannt ist.Since in the present case, the spring only needs to be launched and a subsequent adjustment by tightening the spring or compression of the spring by means of a tool is not required, it can be ensured in a simple manner that always a corresponding spring travel is available, to this end the training is advantageously made so that the lever cooperates with a stop of the frame or box, wherein the spring is partially relaxed.

Der Rahmen oder Kasten, in welchem der federnd gelagerte und schwenkbare Hebel untergebracht ist, ist, wie erwähnt, in besonders einfacher Weise unmittelbar neben einem Gleitstuhl an einer Schwelle bzw. einer Rippenplatte festlegbar, wobei die Ausbildung bevorzugt so getroffen ist, dass der Hebel gegen die Kraft der Feder in eine Position schwenkbar ist, in welche die Rollenoberkante mit der Gleitfläche eines benachbarten Gleitstuhls fluchtet.The frame or box, in which the spring-mounted and pivotable lever is housed, is, as mentioned, in a particularly simple manner immediately adjacent to a sliding chair on a threshold or a rib plate fixable, the training is preferably made so that the lever against the force of the spring is pivotable in a position in which the upper roll edge is aligned with the sliding surface of an adjacent Gleitstuhls.

Ein besonders einfacher Zusammenbau der erfindungsgemäßen Einrichtung lässt sich dadurch sicherstellen, dass der Hebel an seiner der Oberfläche der Schwelle zugewandten Unterseite einen Zentrierfortsatz für eine als Schraubenfeder ausgebildete Feder aufweist, dessen Höhe geringer ist als der maximale Schwenkweg des Hebels.A particularly simple assembly of the device according to the invention can be ensured by the fact that the lever on its surface facing the threshold underside has a centering extension for a trained as a helical spring whose height is less than the maximum pivoting of the lever.

Prinzipiell eignet sich die erfindungsgemäße Ausbildung zur Anordnung an verschiedenen Stellen der beweglichen Zungenschiene. In der Nähe der Einspannstelle ist der Verstellweg einer Zungenschiene relativ klein, wobei für das Abheben der Zunge vom Gleitstuhl während der Umstellung eine entsprechende Federkraft aufgebracht werden soll. Bedingt durch die Elastizität der Zungenschiene kann aber im Zuge des Krümmungsverlaufs einer Weichenzunge die Situation eintreten, dass eine vorzeitige Verriegelung zusätzlicher Sicherungselemente eintritt, obwohl dies noch nicht erforderlich wäre. Für unterschiedliche Einsatzgebiete ist es nun möglich, die erfindungsgemäße Einrichtung in besonders einfacher Weise zu modifizieren, wobei die Vorteile der Nachrüstbarkeit und die Vorteile, wonach die Einrichtung immer in der Draufsicht innerhalb der Oberfläche der Schwellen angeordnet werden sollen, unverändert aufrecht erhalten werden können. Gemäß einer ersten Variante kann die Ausbildung mit Vorteil somit so getroffen werden, dass die Schwenkachse des Hebels zwischen der Backenschiene und der Rolle angeordnet ist und dass die Feder am freien Ende des Hebels angreift, wobei die Rolle in Verschieberichtung der Zungenschiene zwischen der Schwenkachse und der Feder angeordnet ist, wobei eine derartige Ausbildung die Kraft der Feder aufgrund der Hebelübersetzung relativ günstig auf die Rolle überträgt und ein sicheres Abheben der Zungenschiene während des Umstellvorgangs gewährleistet. Die Begrenzung der Aufwärtsbewegung des Hebels und damit der Rollen wird bei einer derartigen Ausbildung mit Vorteil so getroffen, dass der Anschlag des Rahmens oder Kastens mit dem freien Ende des Hebels zusammenwirkt.In principle, the construction according to the invention is suitable for arrangement at different points of the movable tongue rail. In the vicinity of the clamping the adjustment of a tongue rail is relatively small, with a corresponding spring force to be applied for the lifting of the tongue from the sliding chair during the changeover. Due to the elasticity of the tongue rail, however, the situation may occur in the course of the curvature of a switch tongue that premature locking additional security elements occurs, although this not necessary yet. For different applications, it is now possible to modify the device according to the invention in a particularly simple manner, the benefits of retrofitting and the advantages, according to which the device should always be arranged in plan view within the surface of the thresholds can be maintained unchanged. According to a first variant, the training can be advantageously made so that the pivot axis of the lever between the stock rail and the roller is arranged and that the spring acts on the free end of the lever, wherein the role in the direction of displacement of the tongue rail between the pivot axis and the Spring is arranged, with such a design, the force of the spring due to the leverage relatively cheap transfers to the role and ensures a safe lifting of the tongue rail during the Umstellvorgangs. The limitation of the upward movement of the lever and thus the rollers is made in such a design with advantage so that the stop of the frame or box cooperates with the free end of the lever.

Alternativ kann aber die Ausbildung so getroffen werden, dass die Schwenkachse an dem der Backenschiene abgewandten Ende des Hebels angeordnet ist und dass die Feder in Verschieberichtung der Zungenschiene zwischen der Schwenkachse und der Rolle angeordnet ist, wobei die Rolle am der Backenschiene benachbarten freien Ende des Hebels gelagert ist, wobei bei einer derartigen Ausbildung innerhalb des Verstellwegs der Zungenschiene ein definierter Widerstand durch Kollision der Zungenschiene mit der Rolle erzeugt werden kann. Ein vorzeitiges Verriegeln bedingt durch die Elastizität der Zunge kann mit einer derartigen Ausbildung sicher vermieden werden, wobei die Rolle entsprechend höher gestellt in der Einrichtung angeordnet ist, sodass die Zungenschiene unter einem entsprechenden Winkel auf die Rolle aufläuft, bei welchem die Rolle eine große Kraftkomponente in Verstellrichtung aufnehmen kann. Der Zungenfuß gelangt somit aufgrund der höher gestellten Rolle unter einem ausgehend von einem im wesentlichen vertikalen Radius relativ großen Winkel zur Anlage an die Rolle, wobei der längere Verstellweg der Rolle durch die entsprechende Änderung der Anlenkgeometrie und der Abstützung durch die Feder gewährleistet ist. Bei dieser Ausbildung wird in der Folge die Begrenzung der Schwenkbarkeit des Hebels so getroffen, dass der Anschlag des Rahmens oder Kastens zwischen der Rolle und der Schwenkachse des Hebels mit dem Hebel zusammenwirkt.Alternatively, however, the design can be made such that the pivot axis is arranged at the end of the lever remote from the stock rail and that the spring is arranged in the direction of displacement of the tongue rail between the pivot axis and the roller, wherein the roller at the free end of the lever adjacent to the stock rail is stored, wherein in such a configuration within the adjustment path of the tongue rail, a defined resistance can be generated by collision of the tongue rail with the roller. A premature locking due to the elasticity of the tongue can be safely avoided with such a design, wherein the role is placed higher in the device, so that the tongue rail runs at a corresponding angle to the role in which the role of a large force component in Can accommodate adjustment. The tongue foot thus passes due to the higher role under a starting from a substantially vertical radius relatively large angle for engagement with the roller, wherein the longer adjustment path of the roller is ensured by the corresponding change in the Anlenkgeometrie and the support by the spring. In this configuration, the limitation of the pivoting of the lever is subsequently made such that the stop of the frame or box between the roller and the pivot axis of the lever cooperates with the lever.

Während somit die erste Variante eine Umstellhilfe schafft, die im hinteren Bereich der Zungeneinspannung zur Anwendung gelangen kann, bei welcher die Befestigung der Rolleinrichtung in aller Regel so getroffen ist, dass die Rolle innerhalb der Zungenfußbreite mit der Zungenschiene während des Stellvorgangs in Kontakt bleibt, kann die zweite Ausbildung so angeordnet werden, dass die Zungenschiene während der Stellbewegung immer auf dem Gleitstuhl aufliegt und von der Rolle nicht abgehoben wird. Während im ersten Fall die Hubkraft der Rolle durch das Hebelverhältnis der Feder und der Rolle verstärkt wird, wird im zweiten Fall ein längerer Verstellweg der Rolle ermöglicht, um durch eine seitliche elastische Erhöhung des Widerstands eine weitere Verschiebung - bedingt durch die Elastizität der Zungenschiene - zu behindern.Thus, while the first variant provides a Umstellhilfe, which can be used in the rear region of the tongue clamping, in which the attachment of the rolling device is usually made so that the role within the tongue foot width with the tongue rail during the adjustment process remains in contact can the second embodiment are arranged so that the tongue rail always rests on the sliding chair during the adjusting movement and is not lifted off the roller. While in the first case, the lifting force of the roller is reinforced by the lever ratio of the spring and the roller, in the second case, a longer adjustment of the roller is made possible by a lateral elastic increase in the resistance of a further shift - due to the elasticity of the tongue rail - to hinder.

Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.1 eine Schnittdarstellung durch eine erste Ausbildung der erfindungsgemäßen Einrichtung, mit welcher der Verschiebeweg elastisch begrenzt wird, Fig.2 eine perspektivische Darstellung der in Fig.1 dargestellten Einrichtung, Fig.3 einen Schnitt durch eine abgewandelte Einrichtung, bei welcher die Zungenschiene während der Stellbewegung abgehoben werden kann und Fig.4 eine perspektivische Darstellung der Ausbildung nach Fig.3.The invention will be explained in more detail with reference to embodiments shown schematically in the drawing. In this show Fig.1 a sectional view through a first embodiment of the device according to the invention, with which the displacement is elastically limited, Fig.2 a perspective view of in Fig.1 represented device, Figure 3 a section through a modified device in which the tongue rail can be lifted during the adjusting movement and Figure 4 a perspective view of the training Figure 3 ,

In Fig.1 ist mit 1 eine Rippenplatte bezeichnet, auf welcher ein Gleitstuhl 2 festgelegt ist. Die Backenschiene 3 ist in konventioneller Weise an der Rippenplatte bzw. den Schwellen befestigt, wobei die seitliche Verschiebung einer Zungenschiene 4 durch Auflaufen auf eine Rolle 5 elastisch begrenzt wird. Die Rolle 5 ist hierbei an einem Hebel 6 um eine Schwenkachse 7 schwenkbar gelagert und ragt relativ weit über die Oberfläche des Gleitstuhls 2 vor, wodurch die Zungenschiene 4 an einer Stelle gegen die Rolle aufläuft, welche um einen Winkel α gegenüber dem höchsten Punkt der Rolle 5 verschoben ist. Bedingt durch diesen Winkel α wird eine relativ hohe Kraftkomponente in Verschieberichtung aufgenommen, wobei nur ein Teil der Verschiebekraft in Richtung einer Verschwenkung der Rolle wirksam wird. Die Verschwenkung erfolgt hierbei einwärts in einen Kasten 8 entgegen der Kraft einer Feder 9, wobei die Feder 9 zwischen der Schwenkachse 7 und der Rolle 5 an dem Hebel 6 angreift. Der Hebel 6 weist weiters einen Zentrierfortsatz 10 auf, welcher in die Schraubenfeder 9 eintaucht und auf diese Weise den einfachen Zusammenbau ermöglicht. Zur nachträglichen Festlegung einer derartigen Einrichtung an einer Schwelle bzw. einer Rippenplatte genügt es nämlich, die Feder 9 einfach auf die Schwelle oder die Rippenplatte aufzulegen und das Kastenprofil mit dem schwenkbar gelagerten Hebel und der Rolle einfach aufzusetzen und beispielsweise mittels einer Schraube 11 festzulegen. Die Konstruktion ist in der perspektivischen Darstellung gemäß Fig.2 deutlich ersichtlich. Die Schraube 11 durchsetzt hierbei ein Langloch 12, wobei das Kastenprofil in diesem Bereich einen seitlichen Flansch 13 aufweist, welcher die Schwelle seitlich umgreift, sodass mit lediglich einer Schraube 11 eine sichere Festlegung gelingt, bei welcher das Kastenprofil in der Folge nicht mehr um die Schraube 11 verschwenkt werden kann. Aufgrund des Langloches 12 lässt sich die gewünschte Position in weiten Bereichen frei wählen. Im übrigen wurden die Bezugszeichen der Fig.1 beibehalten.In Fig.1 1 is a ribbed plate on which a sliding chair 2 is fixed. The stock rail 3 is in a conventional manner on the ribbed plate or the thresholds fastened, wherein the lateral displacement of a tongue rail 4 is elastically limited by running on a roller 5. The roller 5 is in this case pivotally mounted on a lever 6 about a pivot axis 7 and projects relatively far beyond the surface of the slide chair 2, whereby the tongue rail 4 runs at a location against the roller, which by an angle α relative to the highest point of the role 5 is moved. Due to this angle α, a relatively high force component is absorbed in the direction of displacement, wherein only a part of the displacement force in the direction of pivoting of the roller is effective. The pivoting takes place inwardly in a box 8 against the force of a spring 9, wherein the spring 9 engages between the pivot axis 7 and the roller 5 on the lever 6. The lever 6 further has a centering extension 10, which dips into the coil spring 9 and in this way enables easy assembly. For subsequent determination of such a device on a threshold or a ribbed plate it is sufficient to simply hang the spring 9 on the threshold or the ribbed plate and the box section with the pivotally mounted lever and the role easy to set and set, for example by means of a screw 11. The construction is in the perspective view according to Fig.2 clearly visible. The screw 11 in this case passes through a slot 12, wherein the box section has a lateral flange 13 in this area, which surrounds the threshold side, so that only one screw 11 a secure determination succeeds, in which the box profile in the sequence no longer to the screw 11 can be pivoted. Due to the elongated hole 12, the desired position can be freely selected within wide ranges. Incidentally, the reference numerals of Fig.1 maintained.

Bei der Ausbildung nach Fig.3 wird nun die Kraft der Feder 9 unter Ausnützung entsprechender Hebelwirkungen so umgesetzt, dass eine höhere Kraftkomponente in Richtung des Pfeils 14 durch die Rolle 5 ausgeübt werden kann. Bei dieser Ausbildung liegt die Schwenkachse 7 näher der Backenschiene und das freie Ende des Hebels 6 wird an der Feder 9 abgestützt. Während bei der Ausbildung nach Fig.1 ein Anschlag 15 zwischen Schwenkachse 7 und Rolle 5 zur Wirkung gelangt und auf die Art und Weise ein entsprechend größerer Schwenkweg freigegeben werden kann, wird bei der Ausbildung nach Fig.3 und 4 der Anschlag 16 von einem Rand des Kastenprofils gebildet und wirkt mit dem freien, der Schwenkachse 7 abgewandten Ende des Hebels 6 zusammen. Mit einer derartigen Hebelübersetzung lassen sich höhere Kräfte auf eine über die Rolle 5 beim Verstellweg auflaufende zungenschiene ausüben, sodass ein sicheres Abheben von dem in Fig.3 und 4 nicht mehr dargestellten Gleitstuhl ermöglicht wird. Im übrigen wurden aber auch bei der Darstellung nach Fig.3 und 4 die Bezugszeichen für gleiche Bauteile gleichgehalten, wobei Fig.4 wiederum eine perspektivische Darstellung analog der Darstellung nach Fig.2 zeigt, bei welcher die Schwenkachse 7 der Backenschiene benachbart angeordnet wird und die Rolle 5 zwischen Schwenkachse und der in Fig.4 nicht mehr ersichtlichen, im Kastenprofil untergebrachten Druckfeder 9 angeordnet ist.In training after Figure 3 Now, the force of the spring 9 is converted by taking advantage of corresponding leverage effects so that a higher force component in the direction of the arrow 14 can be exercised by the roller 5. In this embodiment, the pivot axis 7 is closer to the stock rail and the free End of the lever 6 is supported on the spring 9. While in training after Fig.1 a stop 15 between the pivot axis 7 and roller 5 comes into effect and on the way a correspondingly larger pivoting can be released, is in the training after Figure 3 and 4 the stop 16 is formed by an edge of the box profile and cooperates with the free, the pivot axis 7 facing away from the end of the lever 6. With such a lever translation, higher forces can be exerted on an incident on the roller 5 during the adjustment tongue rail, so that a safe lifting of the in Figure 3 and 4 Sliding chair is no longer possible. Incidentally, but also in the presentation after Figure 3 and 4 the reference numerals are kept the same for the same components, wherein Figure 4 again a perspective view analogous to the representation according to Fig.2 shows, in which the pivot axis 7 of the stock rail is disposed adjacent and the roller 5 between the pivot axis and the in Figure 4 no longer apparent, housed in the box profile compression spring 9 is arranged.
