Description
Einrichtung zum Unterstützen der Verschiebebeweαunσ und zum elastischen Verriegeln von beweglichen WeichenteilenDevice for supporting the Verschiebebeweαunσ and for the elastic locking of movable switch parts
Die Erfindung bezieht sich auf eine Einrichtung zum Unterstützen der Verschiebebewegung und zum elastischen Verriegeln von beweglichen Weichenteilen, insbesondere von Weichenzungen von Rillen- schienenweichen, mit einem axial verschieblichen Rohr oder einer Stange, welches an seinem (ihrem) Umfang Ausnehmungen für die Aufnahme von radial verschieblichen Verriegelungsgliedern aufweist und einem das Rohr oder die Stange konzentrisch umgebenden Rohr, welches Ausnehmungen für die Aufnahme von radial auswärts verschobenen Verriegelungsgliedern auf eist .The invention relates to a device for supporting the displacement movement and for elastically locking movable switch parts, in particular switch tongues of grooved rail switches, with an axially displaceable tube or a rod which has recesses on its periphery for receiving radially displaceable ones Has locking members and a tube concentrically surrounding the pipe or rod, which has recesses for receiving radially outwardly displaced locking members.
Zur Verriegelung von beweglichen Weichenteilen ist neben dem sogenannten Klammerspitzenverschluß, in der EP 603 156 AI bereits eine Ausbildung vorgeschlagen worden, bei welcher außeraxiale Belastungen des Verschlusses vermieden werden und eine vollkommen geschlossene Bauweise realisiert werden kann. Bei dieser bekannten Verriegelung, welche bei entsprechender Anordnung von Druckfedern auch als Umstellhilfe zum Einsatz gelangen kann, ist eine Stange in einem axial verschieblichen Rohr angeordnet, welche selbst wiederum in einem ortsfesten Rohr angeordnet war. Im axial verschieblichen Rohr waren Verriegelungsglieder in radialer Richtung verschiebbar geführt, und es waren jeweils Ausnehmungen im ortsfesten Rohr und in der Stange vorgesehen, mit welchen die Verriegelungsglieder bei der Verschiebung bzw. in der Endlage zusammenwirken. Bei der Verwendung einer derartigen Anordnung als Umstellhilfe zum Unterstützen der Verschiebebewegung wurden zwei Druckfedern eingesetzt, wodurch sich insgesamt ein relativ hoher konstruktiver Aufwand ergab. Ausführungsformen einer Umstellhilfe sind auch aus der AT-PS 379 624 bereits bekannt geworden, wobei hier eine Federwippe zum Einsatz gelangte, bei der ein Winkelhebel im Kreuzungspunkt der Arme gelagert ist, wobei ein Kraftspeicher mittels einer Druckfeder gegen die Arme der beiden Winkelhebel abgestützt ist. Zwei Federwippen waren hier über eine Koppelstange mit den beiden Zungenschienen verbunden. Die Erfindung zielt nun darauf ab, eine Einrichtung der eingangs genannten Art dahingehend weiterzubilden, daß, sie besonders kompakt und kurz bauend ausgebildet werden kann und sowohl bei Schienenweichenverstellantrieben als auch als Umstellhilfe für Weichen herangezogen werden kann. Die kompakte Ausbildung soll hierbei die nachträgliche Umrüstung bestehender Weichen in einfacher Weise gestatten und vor allem für Rillenschienenweichen geeignet sein.To lock movable switch parts, in addition to the so-called clamp tip lock, a design has already been proposed in EP 603 156 AI in which off-axis loads on the lock are avoided and a completely closed design can be realized. In this known locking device, which can also be used as a changeover aid with a corresponding arrangement of compression springs, a rod is arranged in an axially displaceable tube, which in turn was arranged in a stationary tube. In the axially displaceable tube, locking members were guided so as to be displaceable in the radial direction, and recesses were provided in the stationary tube and in the rod, with which the locking members interact during the displacement or in the end position. When using such an arrangement as a changeover aid to support the displacement movement, two compression springs were used, which resulted in a relatively high design effort overall. Embodiments of a changeover aid have also become known from AT-PS 379 624, a spring rocker being used here in which an angle lever is mounted at the crossing point of the arms, an energy store being supported against the arms of the two angle levers by means of a compression spring. Two spring rockers were connected to the two tongue rails via a coupling rod. The invention now aims to develop a device of the type mentioned in such a way that it can be made particularly compact and short and can be used both in rail switch actuators and as a changeover aid for switches. The compact design should allow the retrofitting of existing switches in a simple manner and should be particularly suitable for grooved rail switches.
Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß die Verriegelungsglieder in zwei gesonderten in axialem Abstand voneinander zwischen dem Rohr und der Stange angeordneten Rohrschüssen oder Käfigen gelagert sind, und daß zwischen den Rohrschüssen oder Käfigen eine in axialer Richtung wirkende Druckfeder angeordnet ist. Dadurch, daß. nun innerhalb eines Außenrohres zwei gesonderte Rohrschüsse bzw. Kugelkäfige angeordnet sind, genügt die Anordnung einer einzigen Druckfeder zwischen diesen Rohrschüssen, um bei entsprechender Anordnung der Ausnehmungen für die Verriegelungsglieder eine federnde Unterstützung der Umstellbewegung als auch eine federnde Verriegelung der Endlage sicherzustellen. Insgesamt kann die gesamte Anordnung in einem einzigen feststehenden Außenrohr nach außen hin abgeschlossen und damit vor Eindringen gegen Schmutz ausgebildet werden, sodaß die Betriebssicherheit ohne Wartungsaufwand über lange Standzeiten gewährleistet bleibt.To achieve this object, the design according to the invention consists essentially in the fact that the locking members are mounted in two separate pipe sections or cages arranged at an axial distance from one another between the pipe and the rod, and that a compression spring acting in the axial direction is arranged between the pipe sections or cages . As a result of that. now two separate pipe sections or ball cages are arranged within an outer pipe, the arrangement of a single compression spring between these pipe sections is sufficient to ensure a resilient support of the changeover movement as well as a resilient locking of the end position with a corresponding arrangement of the recesses for the locking members. Overall, the entire arrangement can be closed off from the outside in a single, fixed outer tube and thus be formed against penetration against dirt, so that operational safety is guaranteed without maintenance over long service lives.
Mit Vorteil ist die Ausbildung hierbei so getroffen, daß. der axiale Abstand der Ausnehmungen für die Verriegelungsglieder im Rohr verschieden vom axialen Abstand der Ausnehmungen an der Stange gewählt ist. Beim Einsatz der erfindungsgemäßen Einrichtung als Umstellhilfe wird auf diese Weise ein Teil des Verschiebeweges von der Einwirkung der Federkraft freigehalten, sodaß nach einem ersten Komprimieren der Druckfeder ein Teil des Verschiebeweges ohne Überwindung einer weiteren Federkraft er¬ folgen kann, worauf anschließend der Verschiebeweg unter Unterstützung der Kraft der Feder zu Ende zurückgelegt werden kann. Mit Vorteil ist hierbei das außenliegende Rohr ortsfest angeordnet, wobei in besonders einfacher Weise die Stange als die Weichenzungen verbindende Koppelstange ausgebildet sein kann. Eine derartige, die Weichenzungen verbindende Koppelstange kann unmittelbar mit einem Antrieb verbunden werden, sodaß anstelle der bestehenden Betätigungsstange des Weichenantriebes einfach die erfindungsgemäße Einrichtung unmittelbar als Antriebsstange eingesetzt werden kann. Mit Rücksicht auf die kompakten Abmessungen gelingt der Austausch bestehender Koppelstangen ohne bauliche Veränderungen .Advantageously, the training is such that. the axial spacing of the recesses for the locking members in the tube is chosen to be different from the axial spacing of the recesses on the rod. When using the device according to the invention as a Migration Manual a part is in this way kept free of the displacement path of the action of the spring force of the compression spring so that, after a first compressing a portion of the displacement path without having to overcome a further spring force, it can ¬ follow, whereupon then the displacement under the support of the Force of the spring can be completed. In this case, the outer tube is advantageously arranged to be stationary, and the rod can be designed in a particularly simple manner as a coupling rod connecting the switch tongues. Such a coupling rod connecting the switch tongues can be connected directly to a drive, so that instead of the existing actuating rod of the switch drive, the device according to the invention can be used directly as a drive rod. In view of the compact dimensions, the exchange of existing coupling rods is possible without any structural changes.
In besonders vorteilhafter Weise ist die erfindungsgemäße Ausbildung so getroffen, daß die Ausnehmungen für die Verriegelungsglieder als Umfangs- bzw. Ringnuten und die Verriegelungsglieder als Kugeln ausgebildet sind. Durch die Ausbildung der Verriegelungsglieder als Kugeln können die Rohrschüsse in aus dem Lagerbau bekannter Weise als Kugelkäfige ausgebildet sein, sodaß eine besonders einfache Ausbildung ermöglicht wird. Um ein sicheres Ein- und Austreten der Kugeln aus den Umfangs- bzw. Ringnuten sicherzustellen, ist mit Vorteil die Ausbildung so getroffen, daß die Ringnuten trapezförmigen Querschnitt aufweisen.In a particularly advantageous manner, the design according to the invention is such that the recesses for the locking members are designed as circumferential or ring grooves and the locking members as balls. By designing the locking members as balls, the pipe sections can be designed as ball cages in a manner known from bearing construction, so that a particularly simple design is made possible. In order to ensure safe entry and exit of the balls from the circumferential or annular grooves, the design is advantageously made such that the annular grooves have a trapezoidal cross section.
Durch die erfindungsgemäße geschlossene Bauart und die kompakte Ausbildung läßt sich aber auch noch eine zusätzliche hydraulische Dämpfung und damit eine Geräuschminderung des Umstellvorganges in einfacher Weise verwirklichen. Mit Vorteil ist hierbei die Ausbildung so getroffen, daß die Käfige für die Verriegelungsglieder dichtend zwischen Stange und Rohr geführt sind, und daß der die Druckfeder enthaltende Ringraum über nach außen öffnende Rückschlagventile und je eine zu diesen Ventilen parallel geschaltete Drossel mit den außerhalb des Federraumes liegenden Ringräumen verbunden ist. Bei einer derartigen Ausbildung wird die Schlußphase der Umstellbewegung hydraulisch gedämpft, wobei das Fluid aus dem außenliegenden Ringraum in den Federraum zurückgepreßt wird. Bei entsprechender Dimensionierung der Querschnitte kann dies bei vollständiger Füllung der Ringräume mit Fluid sichergestellt werden. Um sicherzustellen, daß die Druckfeder ausgehend aus ihrer federnden Verriegelungslage bzw. Endlage als Einrichtung zum Unterstützen der Verschiebebewegung zum Einsatz gelangen kann, muß gewährleistet werden, daß die Feder im ersten Teil der Verschiebebewegung weiter komprimiert werden kann, um in der Folge unter teilweiser Entspannung die gespeicherte Federkraft als Umstellhilfe wiederum zur Verfügung zu stellen. Mit Vorteil ist daher die Ausbildung so getroffen, daß die Druckfeder in ihrer einen Endstellung der Einrichtung entsprechenden Lage teilweise entspannt ist.Due to the closed design according to the invention and the compact design, additional hydraulic damping and thus noise reduction of the changeover process can also be implemented in a simple manner. Advantageously, the design is such that the cages for the locking members are sealingly guided between the rod and the tube, and that the annular space containing the compression spring has non-return valves that open outwards and a throttle that is connected in parallel with these valves and that is located outside the spring space Annular spaces is connected. With such a design, the final phase of the changeover movement is hydraulically damped, the fluid being pressed out of the outer annular space into the spring space. With appropriate dimensioning of the cross sections, this can be ensured when the annular spaces are completely filled with fluid. In order to ensure that the compression spring can be used as a device to support the displacement movement, starting from its resilient locking position or end position, it must be ensured that the spring can be further compressed in the first part of the displacement movement in order to reduce the pressure in the sequence to make stored spring force available as a changeover aid. The design is therefore advantageously made such that the compression spring is partially relaxed in its position corresponding to one end position of the device.
In konstruktiv besonders einfacher Weise kann die Druckfeder als Schraubenfeder ausgebildet sein.In a structurally particularly simple manner, the compression spring can be designed as a helical spring.
Eine weitere und ggf. zusätzliche Form einer Dämpfung der Umstellbewegung läßt sich dadurch verwirklichen, daß die Stange Anschläge trägt, welche in jeweils einer Endstellung der Einrichtung mit Dämpfungseinrichtungen, insbesondere einem hydraulischen Dämpfer, zusammenwirken.A further and possibly additional form of damping of the changeover movement can be realized in that the rod carries stops which cooperate with damping devices, in particular a hydraulic damper, in each end position of the device.
Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.l eine Ansicht der erfindungsgemäßen Versteileinrichtung teilweise im Schnitt mit dem Weichenantrieb, Fig.2 eine Draufsicht auf die Umstellhilfe in Richtung des Pfeiles II der Fig.l, Fig.3 eine vergrößerte Darstellung der erfindungsgemäßen Einrichtung in einer ersten linken Endlage, Fig.4 eine Darstellung analog der Fig.3 in einer Übergangslage während der Umstellbewegung, Fig.5 den Beginn der Entspannung der Druckfeder zur Unterstützung der Umstellbewegung nach rechts, Fig.6 die rechte Endlage der erfindungsgemäßen Einrichtung und Fig.7 eine schematische Darstellung einer zusätzlichen hydraulischen Dämpfung bei einer Ausbildung nach den Fig.3 bis 6.The invention is explained in more detail below on the basis of exemplary embodiments schematically illustrated in the drawing. 1 shows a view of the adjusting device according to the invention, partly in section with the point machine, FIG. 2 shows a plan view of the changeover aid in the direction of arrow II of FIG. 1, FIG. 3 shows an enlarged illustration of the device according to the invention in a first left end position 4 shows a representation analogous to FIG. 3 in a transition position during the changeover movement, FIG. 5 shows the beginning of the relaxation of the compression spring to support the changeover movement to the right, FIG. 6 shows the right end position of the device according to the invention, and FIG. 7 shows a schematic representation an additional hydraulic damping in an embodiment according to FIGS. 3 to 6.
In Fig.l ist eine Rillenschienenweiche ersichtlich, wobei die beweglichen Weichenzungen mit 1 und die Backenschienen mit 2 be- zeichnet sind. Die Weichenzungen 1 sind über Koppelzapfen 3 mit einer Stange 4 gekoppelt, welche selbst durch einen schematisch angedeuteten Antrieb 5 in Richtung des Doppelpfeiles 6 verschiebbar ist. Mit 7 ist schematiεch die erfindungsgemäße Einrichtung zum Unterstützen der Verschiebebewegung und zum elastischen Verriegeln der Zungenschienen 1 dargestellt, welche in den nachfolgenden Fig.3 bis 7 noch näher verdeutlicht ist.In Fig.l a grooved rail switch can be seen, the movable switch tongues with 1 and the stock rails with 2 are drawn. The switch tongues 1 are coupled via coupling pins 3 to a rod 4, which can itself be displaced in the direction of the double arrow 6 by a schematically indicated drive 5. 7 schematically shows the device according to the invention for supporting the displacement movement and for elastically locking the tongue rails 1, which is illustrated in more detail in the following FIGS. 3 to 7.
In Fig.l ist weiters ersichtlich, daß die Stange 4 Anschläge 8 trägt. Wie sich insbesondere aus der Draufsicht nach Fig.2 ergibt, gelangen diese Anschläge 8 nach einem vorbestimmten Weg a in Anlage an einen schematisch mit 9 angedeuteten hydraulischen Dämpfer, sodaß die Endlage der Verstellbewegung unter dem Einfluß der Dämpfung des hydraulischen Dämpfers 9 erfolgt.In Fig.l it can also be seen that the rod carries 4 stops 8. As can be seen in particular from the top view according to FIG. 2, these stops 8 come into contact with a hydraulic damper, indicated schematically by 9, after a predetermined path a, so that the end position of the adjustment movement takes place under the influence of the damping of the hydraulic damper 9.
Aus der Darstellung nach den Fig.3 bis 6 sind nun die jeweiligen Betriebszustände im Inneren der Einrichtung 7 zum Unterstützen der Verschiebbewegung und zum elastischen Verriegeln der beweglichen Weichenteile näher erläutert. Die Stange 4 weist an ihrem Umfang im Querschnitt trapezförmige Nuten 10 und 11 auf, deren axialer Abstand mit b gewählt ist. In Kugelkäfigen 12 und 13 sind die als Kugeln ausgebildeten Verriegelungsglieder 14 und 15 angeordnet. Das feststehende Außenrohr 16 weist Nuten 17 auf, wobei der wirksame axiale Abstand dieser Nuten 17 voneinander vom Abstand b verschieden gewählt ist.The respective operating states in the interior of the device 7 for supporting the displacement movement and for the elastic locking of the movable switch parts are now explained in more detail from the illustration according to FIGS. 3 to 6. On its circumference, the rod 4 has trapezoidal grooves 10 and 11 in cross section, the axial spacing of which is chosen to be b. The locking members 14 and 15, which are designed as balls, are arranged in ball cages 12 and 13. The fixed outer tube 16 has grooves 17, the effective axial distance between these grooves 17 being chosen to be different from the distance b.
Ausgehend von der in Fig.3 dargestellten linken Endlage der Stange 4, bei welcher die in der Zeichnung nach Fig.3 links angeordnete Zunge unter der Wirkung einer Druckfeder 18 in ihrer Anlagestellung gehalten wird, kann nun bei der Umstellbewegung in Richtung des Pfeiles 19 zunächst die in Fig.4 dargestellte Lage erzielt werden. Die Feder 18 wird zunächst komprimiert, bis die Verriegelungsglieder 14, 15 in eine Lage gelangen, in welcher sie bei weiterer Verschiebung der Stange 4 über einen kurzen Weg relativ zur Stange nicht weiter verschoben werden. Nach dem radialen Auswärtsverlagern der Verriegelungsglieder 14 wird die Stange 4 weiter in Richtung des Pfeiles 19 bewegt, wobei die Verriegelungsglieder 15 radial einwärts in die Nut 11 der Stange eintreten, sodaß die weitere Verschiebung nunmehr durch eine Entspannung der Druckfeder 18 unterstützt wird. Unter teilweiser Entspannung der Druckfeder 18 ausgehend aus der Position, wie sie in Fig.5 dargestellt ist, gelingt es, die Stange 4 in die rechte Endlage zu verschieben, in welcher die federnde Anlage der rechten Zunge unter der Wirkung der Druckfeder 18 gewährleistet ist. Die Verriegelungsglieder 14 sind hierbei in ihrer äußeren Lage in den Ausnehmungen 17 des feststehenden Rohres 16 aufgenommen, wohingegen die Verriegelungsglieder 15 in ihrer radial einwärts verschobenen Lage in der Nut 11 der Stange aufgenommen sind, sodaß die Stange über die Verriegelungsglieder 15 durch die Kraft der Feder 18 in Richtung des Pfeiles 19 nach rechts gedrückt wird.Starting from the left end position of the rod 4 shown in FIG. 3, in which the tongue arranged on the left in the drawing according to FIG. 3 is held in its contact position under the action of a compression spring 18, the changeover movement in the direction of arrow 19 can now be started the position shown in Figure 4 can be achieved. The spring 18 is first compressed until the locking members 14, 15 come into a position in which they are not further displaced over a short distance relative to the rod when the rod 4 is moved further. After the locking members 14 have been displaced radially outward, the rod 4 is moved further in the direction of the arrow 19, the Locking members 15 enter radially inward into the groove 11 of the rod, so that the further displacement is now supported by a relaxation of the compression spring 18. With partial relaxation of the compression spring 18 starting from the position as shown in Figure 5, it is possible to move the rod 4 into the right end position, in which the resilient contact of the right tongue is ensured under the action of the compression spring 18. The locking members 14 are received in their outer position in the recesses 17 of the fixed tube 16, whereas the locking members 15 are received in their radially inwardly displaced position in the groove 11 of the rod, so that the rod via the locking members 15 by the force of the spring 18 is pushed to the right in the direction of arrow 19.
Bei der Ausbildung nach Fig.7 ist nun zusätzlich eine hydraulische Dämpfung integriert, wobei der Federraum 20, welcher die Feder 18 enthält, gegenüber den Ringräumen 21 zu beiden Seiten des Federraumes 20 hydraulisch abgedichtet ist. Es sind jeweils vom Ringraum bzw. Federraum 20 nach auswärts zu den außen liegenden Ringräumen 21 öffnende Rückschlagventile 22 vorgesehen, wobei parallel zu diesen Rückschlagventilen 22 jeweils DrosselnIn the embodiment according to FIG. 7, hydraulic damping is now additionally integrated, the spring chamber 20, which contains the spring 18, being hydraulically sealed off from the annular spaces 21 on both sides of the spring chamber 20. Check valves 22 opening from the annular space or spring space 20 outward to the outer annular spaces 21 are provided, with throttles in each case parallel to these check valves 22
23 angeordnet sind. Bei der Darstellung nach Fig.7 ist die Stange 4 in ihrer rechten Endlage dargestellt, wobei die Druckfeder 18 teilweise entspannt ist. Am Ende dieser Verschiebebewegung in die rechte Endlage wird Medium aus dem rechten Ringraum 21 über die Drossel 23 in den Federraum 20 zurückgedrückt, wobei die Kugelkäfige 12 und 13 jeweils mit Dichtungselementen23 are arranged. 7, the rod 4 is shown in its right end position, the compression spring 18 being partially relaxed. At the end of this displacement movement into the right end position, medium is pressed back from the right annular space 21 via the throttle 23 into the spring space 20, the ball cages 12 and 13 each having sealing elements
24 und 25 versehen sind, sodaß diese Kugelkäfige als Kolben wirksam werden. Die federnde Anpreßbewegung unter Entspannung der Feder 18 wird somit durch das Verdrängen von Fluid aus dem Ringraum 21 über die Drossel 23 in den Federraum 20 gedämpft, wobei Analoges naturgemäß für die Verstellung in die Gegenrichtung gilt. Während der Verstellung kann hierbei jeweils Fluid aus dem Federraum 20 über die Rückschlagventile 22 in den außenliegenden Ringraum 21 gepumpt werden. 24 and 25 are provided so that these ball cages act as pistons. The resilient contact movement with relaxation of the spring 18 is thus damped by the displacement of fluid from the annular space 21 via the throttle 23 into the spring space 20, the same naturally being true for the adjustment in the opposite direction. During the adjustment, fluid can in each case be pumped from the spring chamber 20 via the check valves 22 into the outer annular chamber 21.
