Abstract

In a trailable railway switch drive a coupling device (3) is arranged between a drive unit and the push rod (1) and has a securing roller (10) which is spring loaded in the coupled-end state and engages in a depression (9) of the push rod (1). In order to be able to realise such a coupling device even when the space available is very restricted, two counter rollers (12, 12') are provided which are arranged essentially symmetrically with respect to the direction of movement of the securing roller (10) and are mounted so as to be capable of moving essentially perpendicularly with respect to the direction of movement of the securing roller (10) and are loaded by at least one securing spring (13) in the direction in which they bear against the securing roller (10). <IMAGE>

Description

Die Erfindung betrifft einen auffahrbaren Weichenantrieb, mit einer die Weichenzungen verstellenden Schubstange, sowie mit einer zwischen einer Antriebseinheit und der Schubstange angeordneten Kupplungsvorrichtung, welche eine im eingekuppelten Zustand federbelastet in eine Vertiefung der Schubstange eingreifende Halterolle aufweist.The invention relates to a retractable switch drive, with a push rod which adjusts the switch tongues, and with a coupling device which is arranged between a drive unit and the push rod and which, in the coupled state, has a holding roller which engages in a recess in the push rod in a spring-loaded state.

Anordnungen der genannten Art sind beispielsweise aus der DE-B2 26 06 664, der DE-B1 29 28 194, oder auch der DE-B2 19 52 824 bekannt und ermöglichen ein für viele Anwendungsfälle von Weichenantrieben erwünschtes Auffahren der Weiche auch bei im allgemeinen geforderter Sperre des Weichenantriebes in den Endlagen der Weichenzungen. Die Kupplungsvorrichtung ist aus diesem Grunde gleitbar auf der Schubstange angeordnet und enthält eine Halterolle, welche von einer Haltefeder in eine in der Schubstange befindliche muldenförmige Vertiefung gedrückt wird. Über die Federkraft und die Formgebung der Vertiefung und der Halterolle ist damit eine Schwellkraft definiert, bei deren Überschreitung die ansonsten praktisch starre Verbindung von der Schubstange zur Kupplungsvorrichtung und damit zur Antriebseinheit gelöst wird. Diese Art der automatischen Kupplung ist in der Funktion sehr zuverlässig und hat als einzig wesentlichen Nachteil eigentlich nur einen relativ großen Platzbedarf, was die Verwendbarkeit für verschiedene Anwendungen einschränkt bzw. unerwünschte Auswirkungen im Hinblick auf Beschränkung der Freiheiten bei der Anordnungen sonstiger Bauteile des Weichenantriebes hat.Arrangements of the type mentioned are known, for example, from DE-B2 26 06 664, DE-B1 29 28 194, or also DE-B2 19 52 824 and enable the switch to be opened for many applications of switch drives, even when the switch is generally required Lockout of the turnout drive in the end positions of the turnout tongues. For this reason, the coupling device is slidably arranged on the push rod and contains a holding roller which is pressed by a holding spring into a trough-shaped depression located in the push rod. A threshold force is thus defined via the spring force and the shape of the depression and the holding roller, when this is exceeded, the otherwise practically rigid connection from the push rod to the coupling device and thus to the drive unit is released. This type of automatic clutch is very reliable in function and, as the only major disadvantage, it actually only requires a relatively large amount of space, which limits the usability for different applications or has undesirable effects with regard to restricting the freedom in the arrangement of other components of the point machine.

Aufgabe der vorliegenden Erfindung ist es, einen Weichenantrieb der eingangs genannten Art so zu verbessern, daß die erwähnten Nachteile der bekannten Anordnungen vermieden werden und daß insbesonders auf einfache Weise die Kupplungsvorrichtung zwischen Antriebseinheit und Schubstange bei gleichermaßen sicherer Funktion platzsparender aufgebaut werden kann.The object of the present invention is to improve a point machine of the type mentioned in such a way that the disadvantages of the known arrangements are avoided and that, in particular, the coupling device between the drive unit and the push rod can be constructed in a space-saving manner with an equally reliable function.

Diese Aufgabe wird gemäß der Erfindung bei einem Weichenantrieb der genannten Art dadurch gelöst, daß zwei im wesentlichen symmetrisch bezüglich der Bewegungsrichtung der Halterolle angeordnete Gegenrollen vorgesehen sind, welche im wesentlichen senkrecht zur Bewegungsrichtung der Halterolle beweglich gelagert und von zumindest einer Haltefeder in Richtung zur Anlage an der Halterolle belastet sind. Damit kann auf sehr einfache Weise die bisher bestehende Notwendigkeit, die die Halterolle belastende Haltefeder in Bewegungsrichtung der Halterolle - also normalerweise senkrecht von der Schubstange abstehend - anzuordnen, umgangen werden. Es besteht weitgehende Freiheit hinsichtlich der Anordnung dieser Haltefeder, da diese Feder nun nur mittelbar über die Gegenrollen auf die Halterolle wirkt, womit sich eine sehr gedrängte Konstruktion der Kupplungsvorrichtung bei im wesentlichen gleicher Funktion wie bisher erzielen läßt.This object is achieved according to the invention in a point machine of the type mentioned in that two substantially symmetrical with respect counter-rollers arranged in the direction of movement of the holding roller are provided, which are movably mounted essentially perpendicular to the direction of movement of the holding roller and are loaded by at least one holding spring in the direction of contact with the holding roller. This makes it possible in a very simple manner to circumvent the previously existing need to arrange the retaining spring loading the retaining roller in the direction of movement of the retaining roller - that is to say normally projecting perpendicularly from the push rod. There is extensive freedom with regard to the arrangement of this retaining spring, since this spring now acts only indirectly via the counter-rollers on the retaining roller, so that a very compact design of the coupling device can be achieved with essentially the same function as before.

Die Haltefeder ist in weiterer Ausgestaltung der Erfindung - wie auch bisher zumeist - als Schraubendruckfeder ausgebildet, kann aber nun im wesentlichen parallel zur Schubstange angeordnet werden, was im Hinblick auf die genannte platzsparende Konstruktion optimal ist.In a further embodiment of the invention, the retaining spring is - as previously mostly - designed as a helical compression spring, but can now be arranged essentially parallel to the push rod, which is optimal in view of the space-saving construction mentioned.

Gemäß einer besonders bevorzugten weiteren Ausbildung der Erfindung ist die Halterolle zumindest einseitig in einem in einem Gehäuse der Kupplungsvorrichtung senkrecht zur Schubstange geführten Gleitstein gelagert, wobei die beiden Gegenrollen an im Gehäuse der Kupplungsvorrichtung parallel zur Schubstange verschieblichen Gegenrollengehäusen angeordnet sind, welche über die Haltefeder gegeneinander belastet sind. Dies ergibt eine sehr einfache und zuverlässig funktionierende Konstruktion, da die auf die Gegenrollen wirkende Federkraft unmittelbar auf die Belastung der Halterolle umgesetzt wird.According to a particularly preferred further embodiment of the invention, the holding roller is mounted at least on one side in a sliding block guided perpendicularly to the push rod in a housing of the coupling device, the two counter rollers being arranged on counter roller housings which can be displaced in the housing of the coupling device parallel to the push rod and which are loaded against one another via the retaining spring are. This results in a very simple and reliably functioning construction, since the spring force acting on the counter rollers is directly applied to the load on the holding roller.

Obwohl natürlich bedarfsweise auch zwei oder sogar mehrere Haltefedern zur Belastung der Gegenrollen relativ zur Halterolle vorgesehen sein können, hat sich eine weitere Ausgestaltung der Erfindung besonders vorteilhaft bewährt, gemäß welcher eine einzige Haltefeder einerseits unmittelbar an einem der Gegenrollengehäuse und andererseits über ein Spannstück mit Verstellschraube und Übertragungsbügel am anderen Gegenrollengehäuse angreift. Trotz sehr einfachem konstruktivem Aufbau ist damit auch eine Einstellbarkeit der gewünschten Schwellkraft für das Auslösen der starren Kupplung zwischen Schubstange und Antriebseinheit gegeben.Although, of course, two or even more retaining springs can be provided for loading the counter rollers relative to the retaining roller, a further embodiment of the invention has proven particularly advantageous, according to which a single retaining spring on the one hand directly on one of the counter roller housings and on the other hand via a clamping piece with an adjusting screw and transmission bracket engages the other counter roller housing. Despite the very simple construction, the desired threshold force for triggering the rigid coupling between the push rod and the drive unit can also be adjusted.

Die Erfindung wird im folgenden noch anhand des in der Zeichnung auszugsweise und teilweise schematisch dargestellten Ausführungsbeispiels näher erläutert. Fig. 1 zeigt dabei einen teilweisen Querschnitt durch einen erfindungsgemäßen Weichenantrieb im Bereich der Kupplungsvorrichtung zwischen nicht dargestellter Antriebseinheit und Schubstange und Fig. 2 zeigt eine teilweise Draufsicht auf die Anordnung gemäß Fig. 1 von oben.The invention is explained in more detail below with reference to the exemplary embodiment shown in part and partially schematically in the drawing. 1 shows a partial cross section through a switch drive according to the invention in the area of the coupling device between the drive unit and push rod, not shown, and FIG. 2 shows a partial top view of the arrangement according to FIG. 1 from above.

Eine die nicht dargestellten Weichenzungen bedarfsweise verstellende Schubstange 1 ist in Richtung des Doppelpfeiles 2 beweglich, wobei die hier nicht dargestellte eigentliche Antriebseinheit über eine Kupplungsvorrichtung 3 auf die Schubstange 1 einwirkt. In der in Fig. 1 dargestellten linken Endstellung der Schubstange 1 ist ein am Gehäuse 4 der Kupplungsvorrichtung 3 federbelastet angelenkter linker Festhalteriegel 5 in einer Rast 6 am Gehäuseboden 7 eingerastet, womit die zugehörige Endstellung der über die Schubstange 1 betätigten Weichenzungen fixiert ist. Mit 8 ist ein rechter Festhalteriegel bezeichnet, der wiederum federbelastet am Gehäuse 4 angelenkt ist und in der rechten Endstellung der Schubstange 1 in Eingriff mit einer nicht weiter dargestellten entsprechenden Rast am Gehäuseboden 7 kommt.A push rod 1 which, if necessary, adjusts the switch tongues (not shown) is movable in the direction of the double arrow 2, the actual drive unit (not shown here) acting on the push rod 1 via a coupling device 3. In the left end position of the push rod 1 shown in FIG. 1, a left retaining bolt 5 articulated on the housing 4 of the coupling device 3 is latched in a catch 6 on the housing base 7, whereby the associated end position of the switch tongues actuated via the push rod 1 is fixed. With 8 a right retaining bolt is designated, which in turn is spring-loaded on the housing 4 and in the right end position of the push rod 1 comes into engagement with a corresponding not shown on the housing base 7.

Nicht weiter interessant sind hier die Mechanismen, die am Beginn der Betätigung der Antriebseinheit vorerst zu einem Lösen der Festhalteriegel 5 bzw. 8 und erst dann zu einer entsprechenden Verschiebung der Kupplungsvorrichtung 3 bzw. der Schubstange 1 führen.Of no further interest here are the mechanisms which, at the beginning of the actuation of the drive unit, lead to a loosening of the locking bars 5 or 8 and only then to a corresponding displacement of the coupling device 3 or the push rod 1.

Um ein Auffahren der über die Schubstange 1 betätigten Weiche auch in den über den jeweiligen Festhalteriegel 5 bzw. 8 gesperrten Endstellungen ohne Beschädigung des Weichenantriebes zu ermöglichen weist die Kupplungsvorrichtung 3 eine im dargestellten eingekuppelten Zustand federbelastet in eine Vertiefung 9 der Schubstange 1 eingreifende Halterolle 10 auf, die hier beidseitig in je einem im Gehäuse 4 der Kupplungsvorrichtung 3 senkrecht zur Schubstange 1 geführten Gleitstein 11 gelagert ist. Weiters sind zwei im wesentlichen symmetrisch bezüglich der über die Gleitsteine ermöglichten Bewegungsrichtung der Halterolle 10 angeordnete Gegenrollen 12, 12' vorgesehen, welche wiederum im wesentlichen senkrecht zur Bewegungsrichtung der Halterolle 10 beweglich gelagert und von einer Haltefeder 13 in Richtung zur Anlage an der Halterolle 10 belastet sind.In order to enable opening of the switch operated via the push rod 1 even in the end positions locked via the respective retaining bolts 5 or 8 without damaging the switch drive, the coupling device 3 has a spring-loaded in the coupled state shown in a Recess 9 of the push rod 1 engaging holding roller 10, which is mounted here on both sides in a sliding block 11 guided perpendicularly to the push rod 1 in the housing 4 of the coupling device 3. Furthermore, two counter-rollers 12, 12 'are provided, which are arranged essentially symmetrically with respect to the direction of movement of the holding roller 10, which are in turn movably mounted substantially perpendicular to the direction of movement of the holding roller 10 and loaded by a retaining spring 13 in the direction of contact with the holding roller 10 are.

Die Haltefeder 13 ist hier als Schraubendruckfeder ausgebildet und im wesentlichen parallel zur Schubstange 1 angeordnet, womit sich eine sehr kompakte Bauweise bei gleichzeitig sicherer Funktion der Kupplungsvorrichtung 3 ergibt.The retaining spring 13 is designed here as a helical compression spring and is arranged essentially parallel to the push rod 1, which results in a very compact design with a safe function of the coupling device 3.

Die beiden Gegenrollen 12, 12' sind an im Gehäuse 4 der Kupplungsvorrichtung 3 parallel zur Schubstange verschieblichen Gegenrollengehäusen 14, 15 angeordnet, welche über die Haltefeder 13 gegeneinander federbelastet sind. Die hier einzige Haltefeder 13 ist zu diesem Zwecke einerseits unmittelbar am Gegenrollengehäuse 14 und andererseits über ein Spannstück 16 mit Verstellschraube 17 und Übertragungsbügel 18 - hier bestehend im wesentlichen aus den beiden Gewindestangen 19 sowie den Kopfstücken 20 - am anderen Gegenrollengehäuse 15 abgestützt, was auf sehr einfache Weise eine Umlenkung der Wirkung der Federkraft auf die Belastung der Halterolle 10 ermöglicht.The two counter rollers 12, 12 'are arranged on counter roller housings 14, 15 which are displaceable parallel to the push rod in the housing 4 of the coupling device 3 and which are spring-loaded against one another via the holding spring 13. The only retaining spring 13 is supported for this purpose on the one hand directly on the counter-roller housing 14 and on the other hand via a clamping piece 16 with adjusting screw 17 and transmission bracket 18 - here consisting essentially of the two threaded rods 19 and the head pieces 20 - on the other counter-roller housing 15, which is very allows a simple deflection of the effect of the spring force on the load on the holding roller 10.

Beim Auffahren der Weiche wird die Schubstange 1 (bei über die Festhalteriegel 5 bzw. 8 festgehaltener Kupplungsvorrichtung samt Halterolle 10) mit ihrer Vertiefung 9 aus dem Eingriffsbereich der Halterolle 10 gedrückt, was zu einem Zurückweichen der Halterolle 10 gegen die Wirkung der federbelasteten Gegenrollen 12, 12' führt, welche ihrerseits zusammen mit den Gegenrollengehäusen 14, 15 auseinandergedrückt werden. Die Schubstange 1 ist damit relativ zur Kupplungsvorrichtung 3 bzw. zur Antriebseinheit frei beweglich, bis es bei Übereinstimmung der Position der Halterolle 10 mit der Vertiefung 9 wiederum zu einer Kuppelung kommt.When the switch is opened, the push rod 1 (with the coupling device and the holding roller 10 held in place via the holding bolts 5 or 8) is pressed with its recess 9 out of the engagement area of the holding roller 10, which causes the holding roller 10 to retreat against the action of the spring-loaded counter rollers 12. 12 'leads, which in turn are pressed apart together with the counter roller housings 14, 15. The push rod 1 is thus freely movable relative to the coupling device 3 or to the drive unit until it matches the position of the holding roller 10 with the recess 9 in turn comes to a coupling.

Anstelle der dargestellten einzelnen, als Schraubenfeder ausgebildeten Haltefeder 13 könnten natürlich auf geeignete Weise auch zwei oder mehrere, auch beispielsweise als Tellerfedern oder dergleichen ausgebildete Federn, eventuell auch auf beiden Seiten der Halterolle 10, angeordnet sein - ebenfalls möglich wäre auch eine winkelmäßig gegenüber der Darstellung abweichende Anordnung der Bewegungsmöglichkeiten von Halterolle 10 und/oder Gegenrollen 12, 12', womit eine unter Umständen erforderliche Berücksichtigung spezieller örtlicher Gegebenheiten möglich ist.Instead of the individual retaining spring 13 shown, which is designed as a helical spring, two or more springs, which are also designed, for example, as plate springs or the like, could of course also be arranged in a suitable manner, possibly also on both sides of the holding roller 10 - an angle with respect to the illustration would also be possible Different arrangement of the movement possibilities of the holding roller 10 and / or counter-rollers 12, 12 ', with which a consideration of special local conditions which may be necessary is possible.
