Description

Die vorliegende Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device according to the Preamble of claim 1.

Aus der CH-PS 621168 ist eine Hohlschwelle mit integriertem Weichenantrieb und mit einer - in dieser Schrift genannten - Anzeigevorrichtung bekannt, die anzeigt, ob die an der Stockschiene anliegende Weichenzunge die jeweilige Endstellung erlangt hat. Aus WO 94/27853 ist ferner ein in einer Hohlschwelle integriertes modulares Weichenstellsystem beschrieben, das aus einzelnen, teilweise wahlfrei austauschbaren Modulen besteht.From CH-PS 621168 is a hollow sleeper with integrated Point machine and with a - mentioned in this document - Display device is known which indicates whether the on the floor rail adjoining switch blade the respective end position has attained. From WO 94/27853 is also a in a Hollow sill integrated modular point system described, that of individual, sometimes optional interchangeable Modules exists.

Weichen sind durch Witterungseinflüsse und durch das Befahren durch Züge einer hohen Beanspruchung ausgesetzt. Insbesondere können sich dadurch bei der Montage vorgenommene Einstellungen und Justierungen verändern. Die Justierungen beziehen sich auf die Riegelstangen, die der sicheren Detektion der jeweiligen Endstellung der an die Stockschiene anliegenden Weichenzunge dient. Diese Riegelstangen sind dabei Bestandteil eines sogenannten Weichen- oder Zungenkontrollgestänges. Dazu ist die Riegelstange mit einer Detektionseinrichtung wie beispielsweise mit einem Endschalter mechanisch verbunden, welche abhängig von der Endlage der Weichenzunge einen Stromkreis schaltet. Da die Platzverhältnisse in einer Hohlschwelle sehr begrenzt sind und dadurch die Zugänglichkeit zu den Komponenten stark erschwert ist, muss eine Nachjustierung oft mit dem Ausbau einzelner Komponenten oder Module sowie mit mühsamer Handarbeit vorgenommen werden. Mittels Gewinden kann eine Justierung mit einer Auflösung in der Grösse einer Gewindesteigung, z.B. M24 x 3 mm, vorgenommen werden, gewünscht ist insbesondere für die Riegelstange ein feinerer Einstellbereich der Justierung. Durch das Drehen um 180° und Vielfache davon der meist als Gewindestange ausgebildeten Riegelstange, ist eine feinere Einstellbarkeit möglich, jedoch mit zusätzlichem Aufwand verbunden, da diese Riegelstangen nach erfolgter Drehung wieder blockiert werden müssen.Turnouts are due to weather conditions and by driving exposed by trains of high stress. Especially This can be done during installation settings and change adjustments. The adjustments relate on the locking bars, the safe detection the respective end position of the voltage applied to the floor rail Switch blade serves. These locking bars are part of it a so-called switch or tongue control linkage. For this purpose, the locking bar with a detection device such as with a limit switch mechanically connected, which depends on the final position of the Switch tongue switches a circuit. Because the space conditions are very limited in a hollow sleeper and thereby the accessibility to the components is very difficult A readjustment often involves the removal of individual components or modules and made with laborious manual work become. By means of threads can be an adjustment with a resolution in the size of a thread pitch, e.g. M24 x 3 mm, be made is desired in particular for the locking bar a finer adjustment range of the adjustment. By turning by 180 ° and multiples of it usually as a threaded rod trained locking bar, is a finer adjustability possible, but with additional effort, because these locking bars after the turn again need to be blocked.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung anzugeben, die das Justieren der Riegelstange auf einfache Weise ermöglicht.The present invention is therefore based on the object to provide a device that adjusting the locking bar in a simple way.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Massnahmen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is specified by the in claim 1 Measures solved. Advantageous embodiments of the invention are given in further claims.

Dadurch dass in einer ersten Ausnehmung des Riegelstangenkopfes ein Klemmstück führbar ist, wobei das Klemmstück eine Oeffnung zur Durchführung der Riegelstange aufweist und die Oeffnung einseitig mit der Riegelstange mit einem Formschluss einrastbar und mit einem Feststellmittel fixierbar ist kann eine Justierung der Lage einfach vorgenommen werden: Lediglich durch Lösen des Feststellmittels kann die Riegelstange auf eine nächste Position eines Rasters eingestellt werden.Characterized in that in a first recess of the locking bar head a clamping piece is feasible, wherein the clamping piece a Opening for carrying out the locking bar and the Opening on one side with the locking bar with a positive connection latched and can be fixed with a locking means can an adjustment of the situation can be easily made: only by loosening the locking means, the locking bar be set to a next position of a grid.

So können sich die folgenden Vorteile zusätzlich ergeben:

  • i) Ein als Schraube vorgesehenes Feststellmittel ermöglicht eine leichte Zugänglichkeit von oben (Patentanspruch 6).
  • ii) Eine Verbindung mit einem Exzenter-Bolzen zwischen Riegelstangenkopf und Weichenzunge erlaubt eine einfache Feinjustierung, es braucht dazu lediglich der Exzenter-Bolzen um 90° oder 180° gedreht zu werden. (Patentanspruch 7).
  • iii) Ein Durchgangsloch im Kopfteil des Exzenter-Bolzens gestattet einerseits durch Einstecken eines einfachen Werkzeuges oder eines Sicherungsmittels ein leichtes Drehen und andererseits in einer Endposition das Anbringen eines Sicherungsmittels, beispielsweise eine Vorsteckfeder (Patentanspruch 8).
    • This may result in the following additional benefits:
  • i) A provided as a screw locking means allows easy access from above (claim 6).
  • ii) A connection with an eccentric bolt between locking bar head and switch blade allows easy fine adjustment, it only needs the eccentric bolt to be rotated by 90 ° or 180 °. (Claim 7).
  • iii) A through hole in the head part of the eccentric bolt allows on the one hand by inserting a simple tool or a securing means a slight turning and on the other hand in an end position attaching a securing means, for example a Vorsteckfeder (claim 8).

    Figur 4 zeigt einen Querschnitt durch eine Seite einer Weiche, aus dem eine Stockschiene 22, eine hier in anliegender Position gezeichnete Weichenzunge 23, mit der ein Riegelstangenkopf 1 verbunden ist. Der Riegelstangenkopf 1 ist seinerseits mit einer Riegelstange 2 verbunden.Figure 4 shows a cross section through one side of a Weiche, from the one floor rail 22, one here in adjoining Positioned switch blade 23, with a latch rod end 1 is connected. The locking bar head 1 is in turn connected to a locking bar 2.

    Figur 1 zeigt den detaillierten Schnitt durch den Riegelstangenkopf 1. Ein Ausschnitt der Riegelstange 2 ist als Gewindestange 5 dargestellt, das Gewinde braucht jedoch nicht über die ganze Länge der Riegelstange 2 vorhanden zu sein. Die Ausnehmung 9 dient der Verbindung mit einer Weichenzunge 23. Die Riegelstange 2 ist mit einem oder mehreren vorzugsweise in einer Antriebseinheit der Weiche angeordneten Endschaltern verbunden - in Fig. 1 nicht dargestellt -. Der oder die Endschalter schalten einen elektrischen Stromkreis in Abhängigkeit einer definierten Endlage einer Weichenzunge 23. Der Riegelstangenkopf 1 enthält eine Ausnehmung 20, in der das Klemmstück 10 vertikal geführt ist. Die Riegelstange 2 ist durch das Klemmstück 10 geführt und somit mit dem Riegelkopf 1 fest verbindbar. Mit A2 ist eine feste Lage der Riegelstange 2 relativ zum Klemmstück 10 und somit zum Riegelkopf 1 dargestellt. Diese feste Lage A2 wird sichergestellt durch die Feststellschraube 14, die über ein Gewinde 18 das Klemmstück 10 mit der Riegelstange 2 gegen den Riegelkopf 1 mit einem Formschluss zwischen Klemmstück 10 und Gewindestange 5 klemmt. Das Festziehen der Feststellschraube 14 erfolgt über einen von oben leicht zugänglichen Schraubenkopf 15, beispielsweise kann der Schraubenkopf 15 als Sechskantkopf ausgebildet sein. Nicht dargestellt in der Fig. 1 ist eine Schraubensicherung, die ein Lösen der Feststellschraube 14 durch auftretende Vibrationen verhindert.FIG. 1 shows the detailed section through the locking bar head 1. A section of the locking bar 2 is a threaded rod 5, but the thread does not need over the entire length of the locking bar 2 to be present. The recess 9 serves to connect to a switch tongue 23. The locking bar 2 is preferably one or more in a drive unit of the switch arranged limit switches connected - not shown in Fig. 1 -. The river Oder the limit switches switch an electric circuit depending on a defined end position of a switch tongue 23rd The locking bar head 1 includes a recess 20 in which the clamping piece 10 is guided vertically. The locking bar 2 is guided by the clamping piece 10 and thus with the bolt head 1 firmly connected. With A2 is a fixed position of Lock bar 2 relative to the clamping piece 10 and thus to Bolt head 1 shown. This fixed position A2 is ensured through the locking screw 14, which has a thread 18, the clamping piece 10 with the locking bar 2 against the bolt head 1 with a positive connection between clamping piece 10 and threaded rod 5 is stuck. Tighten the locking screw 14 via a screw head that is easily accessible from above 15, for example, the screw head 15 as a hexagonal head be educated. Not shown in FIG. 1 is a screw lock, which is a loosening of the locking screw 14 prevented by vibrations occurring.

    Durch das Lösen der Feststellschraube 14 kann das Klemmstück 10 leicht nach unten bewegt werden und ermöglicht die Längseinstellbarkeit der Riegelstange 2 wie folgt: Der Formschluss zwischen Gewindestange 5 und einem Halbkreis 11 mit Gewinde wird aufgehoben und dadurch kann die Riegelstange 2 quer zum Klemmstück 10 bewegt werden und in der gewünschten Relativposition eingerastet werden. In einer Aufsicht ist dazu in Fig. 2 eine ovale Oeffnung 12 des Klemmstücks 10 dargestellt. Diese ovale Oeffnung 12 wird nach unten durch den Halbkreis 11 mit einem Gewinde und nach oben durch einen gegenüber dem Halbkreis 11 leicht versetzten Halbkreis 13 mit glatter Oberfläche begrenzt. Diese Versetzung liegt typischerweise in einem Bereich von 2.5 bis 5 mm. Durch ein Wiederanziehen der Feststellschraube 14 erfolgt wiederum eine formschlüssige Verbindung - in Fig. 1 mit der Lage A2 bezeichnet - zwischen Halbkreis 11 mit Gewinde und Gewindestange 5. Durch die Dimensionierung des Klemmstücks 10 umfasst dieser Formschluss recht viele Gewindegänge. Dies erlaubt, anstelle eines Gewindes z.B. M24 mit der üblichen Steigung 3 mm ein Feingewinde mit beispielsweise 2 mm Steigung vorzusehen. Dadurch ist eine feinere Einstellbarkeit der Riegelstange 2 gegeben, ohne dass durch weitere Manipulationen wie z.B. durch Drehen der Riegelstange 2, eine Feineinstellung vorgenommen werden muss.By loosening the locking screw 14, the clamping piece 10 can be moved down slightly and allows the longitudinal adjustability the locking bar 2 as follows: The positive connection between threaded rod 5 and a semi-circle 11 with thread is canceled and thereby the locking bar 2 transverse to Clamp 10 are moved and in the desired Relative position are locked. In a supervision is 2, an oval opening 12 of the clamping piece 10 is shown in FIG. This oval opening 12 is down through the Semicircle 11 with a thread and up through a with respect to the semicircle 11 slightly offset semicircle 13 with smooth surface limited. This offset is typically in a range of 2.5 to 5 mm. Through a Re-tighten the locking screw 14 is again a positive connection - referred to in Fig. 1 with the position A2 - between half-circle 11 with thread and threaded rod 5. Includes by the dimensioning of the clamping piece 10 this form fit quite a few threads. This allows instead of a thread, e.g. M24 with the usual Gradient 3 mm a fine thread with, for example, 2 mm Provide slope. This is a finer adjustability given the locking bar 2, without further manipulation such as. by turning the locking bar 2, a Fine adjustment must be made.

    In besonders vorteilhafter Ausführungsform der vorliegenden Erfindung ist eine noch feinere Einstellbarkeit an der Verbindung Riegelkopf 1 - Weichenzunge 23 wie folgt erreichbar: In Fig. 1 oben ist für die Verbindung Riegelkopf 1 - Weichenzunge 23 eine Ausnehmung 9 der Höhe le und eine fluchtende Bohrung mit der Achse 19 vorgesehen. Die fluchtende Bohrung nimmt je eine Lagerbüchse 3 und 4 auf. Dabei ist der Innendurchmesser d1 der Lagerbüchse 3 grösser als der Innendurchmesser d2 der Lagerbüchse 4. Diese durch die beiden Lagerbüchsen 3 und 4 definierte konzentrische Oeffnung ist für die Aufnahme eines Exzenter-Bolzens 6 vorgesehen.In a particularly advantageous embodiment of the present invention, an even finer adjustability at the connection bolt head 1 - switch blade 23 can be achieved as follows: In Fig. 1 above is for the connection bolt head 1 - switch blade 23 a recess 9 of height l e and an aligned hole with the axis 19 is provided. The aligned bore receives a respective bearing bush 3 and 4. In this case, the inner diameter d1 of the bearing bush 3 is larger than the inner diameter d2 of the bearing bush 4. This defined by the two bearing bushes 3 and 4 concentric opening is provided for receiving an eccentric pin 6.

    Der in Fig. 3 dargestellte Exzenter-Bolzens 6 weist im Mittelteil auf einer Länge le einer gegenüber der Achse 21 versetzten zylindrischen Teil auf. Dieser Mittelteil greift in eine entsprechende Bohrung einer Nocke der Höhe le ein, die Teil der Weichenzunge 23 ist - siehe dazu die Darstellung in Fig. 4 - oder welche Nocke mit der Weichenzunge 23 verbunden ist, in den Figuren nicht dargestellt. Die Ansicht in Fig. 3 ist so gewählt, dass mit e1 gegenüber dem Durchmesser d1 und mit e2 gegenüber dem Durchmesser d2 die grösste Versetzung dargestellt ist. Die Versetzung relativ zum Durchmesser d1 ist mit e1 bezeichnet, jene relativ zum Durchmesser d2 mit e2. Typische Werte für e1 und e2 liegen in einem Bereich von 0.5 bis 2 mm, üblicherweise wird für e1 und e2 der gleiche Werte vorgesehen, dies ist aber nicht zwingend. In dieser Ausführungsform fluchtet der exzentrische Mittelteil einmal mit dem oberen Zylinder mit dem Durchmesser d1 und einmal mit dem unteren Zylinder mit dem Durchmesser d2, diese Fluchtung ist jedoch nicht zwingend, denkbar ist auch, dass sich d1 und d2 stärker unterscheiden und die exzentrische Ausdehnung, d.h. der zugehörige exzentrische Kreis sich auch innerhalb der durch die beiden Durchmesser d1 und d2 definierten Kreise befinden kann. Der Exzenter-Bolzen 6 weist im Kopfteil je eine um 90° verdrehte Bohrung 7 bzw. 8 auf. Diese Bohrung ist für die Aufnahme einer Vorsteckfeder oder eines anderen geeigneten Sicherungselementes vorgesehen, die die Lage des Exzenter-Bolzens 6 relativ zum Riegelstangenkopf 1 fixiert. Dazu ist im Riegelstangenkopf 1 ein Durchgangsloch 17 vorgesehen, vgl. Fig. 1. The eccentric pin 6 shown in Fig. 3 has in the central part over a length l e of a relative to the axis 21 offset cylindrical portion. This central portion engages in a corresponding hole of a cam of the height l e a, which is part of the switch tongue 23 is -. See the representation in Figure 4 - or the cam being connected to the switch tongue 23, not shown in the figures. The view in FIG. 3 is selected so that the greatest displacement is shown with e1 in relation to the diameter d1 and with e2 in relation to the diameter d2. The offset relative to the diameter d1 is denoted by e1, that relative to the diameter d2 by e2. Typical values for e1 and e2 are in a range of 0.5 to 2 mm; usually the same values are provided for e1 and e2, but this is not mandatory. In this embodiment, the eccentric center part is aligned once with the upper cylinder with the diameter d1 and once with the lower cylinder with the diameter d2, this alignment is not mandatory, it is also conceivable that d1 and d2 differ more and the eccentric extent, ie the associated eccentric circle can also be located within the circles defined by the two diameters d1 and d2. The eccentric pin 6 has in the head part depending on a 90 ° twisted bore 7 and 8 respectively. This hole is provided for receiving a Vorsteckfeder or other suitable securing element which fixes the position of the eccentric pin 6 relative to the locking rod end 1. For this purpose, a through hole 17 is provided in the locking bar head 1, cf. Fig. 1.

    Bei der Montage eines Weichenstellsystems kann zunächst mit dem Exzenter-Bolzen 6 eine Mitteleinstellung vorgenommen werden und mittels Klemmstück 10 die Lage der Riegelstange 2 festgelegt werden. Durch ein nachfolgendes Drehen des Exzenter-Bolzens 6 kann noch die Feinjustierung vorgenommen werden. Es kann aber auch zweckmässig sein, den Exzenter-Bolzen 6 zum vorneherein in eine - gegenüber der im Verlaufe der Zeit entstehenden Abweichung - "Minimalposition" zu versetzen und die erstmalige Justierung mit dem Klemmstück 10 und der Riegelstange 2 bzw. dem Gewinde 5 vorzunehmen. Dies hat den Vorteil, spätere erforderliche Justierungen auf sehr einfache Weise durch Drehen des Exzenter-Bolzens 6 allein vornehmen zu können.When assembling a points system can first with the eccentric pin 6 made an adjustment be and by means of clamping piece 10, the position of the locking bar. 2 be determined. By subsequently turning the Eccentric bolt 6 can still made the fine adjustment become. But it may also be appropriate, the eccentric bolt 6 at the outset in one - compared to the course the time deviating - "minimum position" to move and the first-time adjustment with the clamping piece 10th and the locking bar 2 and the thread 5 make. This has the advantage of later required adjustments on very much simple way by turning the eccentric pin 6 alone to be able to make.

    Die Ausnehmung 20 für die Aufnahme des Klemmstückes 10 kann einen kreisförmigen, einen rechteckförmigen oder ein quadratischen Querschnitt aufweisen.The recess 20 for receiving the clamping piece 10 can a circular, a rectangular or a square Have cross-section.

    Der vorstehend beschriebene Formschluss zwischen Klemmstück 6 und Riegelstange 2 ist nicht auf ein Gewinde 5 und den korrespondierenden Halbkreis 11 mit Gewinde beschränkt. Möglich ist auch ein querrippenartiger Formschluss zwischen Klemmstück 6 und Riegelstange 2. Diese Querrippen können symmetrisch oder asymmetrisch ausgebildet sein, aus herstellungstechnischen Gründen erweisen sich trapezförmige Rippen als besonders vorteilhaft. Der Abstand der Trapeze liegt typischerweise in einem Bereich von 1.5 bis 2.5 mm und dadurch ist die Riegelstange 2 wie beim Gewinde relativ zum Klemmstück 10 einrastbar. The above-described positive connection between clamping piece. 6 and locking bar 2 is not on a thread 5 and the corresponding semicircle 11 limited with thread. It is also possible a transverse rib-like form fit between Clamp 6 and locking bar 2. These transverse ribs can be formed symmetrically or asymmetrically, from manufacturing technology The reasons are trapezoidal Ribs as particularly advantageous. The distance of the trapeze is typically in a range of 1.5 to 2.5 mm and As a result, the locking bar 2 is like the thread relative to Clamp 10 can be latched.
