Description

Vorrichtung zum Umstellen von WeichenzungenDevice for switching switch tongues
Die Erfindung betrifft eine Vorrichtung in einer Weiche zum Andrücken einer Zunge an eine Backenschiene und gleichzeitigem Abziehen der anderen Zunge von einer gegenüberliegenden Backenschiene.The invention relates to a device in a switch for pressing a tongue against a stock rail and simultaneously pulling the other tongue from an opposing stock rail.
Bei höheren Geschwindigkeiten in Weichen von Gleisen mit Durchschnittsge¬ schwindigkeiten von 160 km/h, insbesondere aber auch in Weichen von Hochge¬ schwindigkeitsstrecken bis 250 km/h im geraden Strang, ist es erforderlich, daß die jeweilige an einer Backenschiene anliegende Zunge eine einwandfreie Kontaktanlage sowohl im Anschlagbereich der Zunge als auch an den nachfolgenden Stützknaggen aufweist. Dies ist sehr wichtig, um einer Bewegung beim Befahren unter Belastung der nicht an ihren Stützelementen anliegenden Zungenbereiche, was praktisch einer Spurverengung gleichkommt, vorzubeugen. Deshalb ist es zur Vermeidung einer Spurverengung erforderlich, daß vor dem Befahren alle Zungenbereiche an den Stützelementen anliegen. Bei der anderen Zunge, nämlich der von der Backenschiene abliegenden Zunge, sollte der Abstand zwischen abliegender Zunge und der dazuge¬ hörigen Backenschiene nicht weniger als 58 mm betragen.At higher speeds in turnouts of tracks with average speeds of 160 km / h, but in particular also in turnouts of high-speed lines up to 250 km / h in a straight line, it is necessary that the respective tongue resting on a stock rail has a perfect contact system has both in the stop area of the tongue and on the subsequent support lugs. This is very important in order to prevent movement when driving under load on the tongue areas not in contact with their support elements, which is practically equivalent to a narrowing of the track. Therefore, in order to avoid narrowing of the lane, it is necessary for all tongue areas to rest on the support elements before driving on them. In the other tongue, namely the tongue lying away from the stock rail, the distance between the lying tongue and the associated stock rail should not be less than 58 mm.
Die Ursache für ein häufiges Nichteinhalten eines Mindestabstandes von 58 mm bzw. das Anliegen der Zunge auf ihrer gesamten Länge, ist ein sogenanntes "Hängenbleiben" der Zunge beim Umstellen, hervorgerufen durch hohe Reibungskräfte, aber auch eventuell auftretende plastische Horizontalverformungen.The reason for a frequent failure to keep a minimum distance of 58 mm or the tongue resting on its entire length is a so-called "sticking" of the tongue when changing over, caused by high frictional forces, but also possibly occurring plastic horizontal deformations.
Um die beiden Mängel, zum einen das Nichtanliegen der zu befahrenden Zunge und zum andern der nicht weit genug öffnenden Rille bzw. eines nicht ausreichenden Abstandes der von der Backenschiene abliegenden Zunge, zu beheben, werden im Bereich der engsten Rille, das ist meistens im Bereich der vollen Kopfbreite der Zunge, sogenannte Klammermittelverschlüsse bzw. Gabelmittelverschlüsse eingebaut. Damit läßt sich erreichen, daß sowohl die zu befahrende Zunge überall an den dafür vorgesehenen Abstützbereichen anliegt als auch zwischen Backenschiene und abliegender Zunge die Mindestdurchfahrrille nicht unterschritten wird.To the two shortcomings, on the one hand the non-contact of the tongue to be driven and on the other hand the not enough opening groove or one insufficient To fix the distance from the tongue away from the stock rail, so-called clamp middle closures or fork middle closures are installed in the area of the narrowest groove, that is mostly in the area of the full head width of the tongue. In this way it can be achieved that the tongue to be driven is in contact with the support areas provided for this purpose, and that the minimum drive-through groove is not undershot between the stock rail and the remote tongue.
Bei den Klammermittelverschlüssen wird die anliegende Zunge durch die Klammer mit der Backenschiene verklammert, während beim Gabelmittelverschluß die anliegende Zunge nur mit einer bestimmten Kraft an die Backenschiene gepreßt und die ablie¬ gende Zunge auf eine Rillenweite von 58 mm aufgezogen wird.In the case of the middle clamps, the adjacent tongue is clamped by the clamp to the stock rail, while the closed tab is only pressed against the stock rail with a certain force and the lying tongue is opened to a groove width of 58 mm.
Bei den bisherigen, meist älteren Stellwerken ist zur Verstellung der Zunge nur ein Antrieb mit Zungenprüfern an der Zungenspitze vorgesehen. Um die hinter der Zungenspitze liegenden Bereiche vor dem Befahren der anliegenden Zunge zum Kontakt zu bringen und die abliegende Zunge weit genug von der Backenschiene abzuziehen, werden die Klammermittel- und Gabelmittelverschlüsse unter Zuhilfe¬ nahme von Antriebsgestängen, welche von einem Zungenspitzenmotor verstellt werden, entsprechend positioniert. Dieses Antriebsgestänge respektive Übertragungs¬ gestänge, das vor den Köpfen von Schwellen angeordnet ist, macht das zur Erhöhung der Lagestabilität notwendige Verdichten des Schotters vor Kopf der Schwelle praktisch unmöglich. Dadurch wird die Lagestabilität der Schwelle herabgesetzt, was zu Gleisverwerfungen und meistens zu erhöhtem Unterhaltungsaufwand führt.In the previous, mostly older signal boxes, only one drive with tongue testers is provided at the tip of the tongue to adjust the tongue. In order to bring the areas behind the tip of the tongue into contact before driving onto the adjacent tongue and to pull the tongue away from the stock rail far enough, the clamp means and fork means locks are appropriately positioned with the aid of drive linkages which are adjusted by a tip motor . This drive linkage or transmission linkage, which is arranged in front of the heads of sleepers, makes the compression of the ballast in front of the headers necessary to increase the positional stability practically impossible. This reduces the positional stability of the sleeper, which leads to warping of the track and mostly to increased maintenance.
Das Problem des bisherigen Handstopfens von außen der beiden Schwellenfachschwellen mit Antriebs- oder auch Zungenprüfgestänge ist durch den Einsatz von Kastenschwellen sowohl für Weichen auf Holzschwellen als auch für Weichen auf Betonschwellen weitestgehend behoben worden. Allerdings bringt auch hier das Antriebsgestänge vom Zungenspitzenmotor zum ersten Klammer- oder auch Gabelmittelverschluß die schon erwähnten größeren Nachteile mit sich. Weiterhin sind im Stand der Technik zur Verstellung der Zungen in Weichen sogenannte Federwippen bekannt. Diese sind im Schwellenfach angeordnet, d.h., daß die beiden Schwellen eines Schwellenfaches nur einseitig und durch Handstopfen stopfbar sind. Von der Innenseite der beiden Schwellen eines Schwellenfaches her ist weder ein maschinelles noch ein Stopfen von Hand möglich. Die bekannten Federwippen haben weiterhin den Nachteil, daß sie nur eine bzw. maximal zwei Federn aufweisen. Bei einem Bruch der einzigen Feder ist die Federwippe vollkommen funktionsunfähig. Ähnlich verhält es sich bei zwei vorhandenen Federn und dem Bruch einer Feder, da die einzig verbleibende Feder die benötigte Kraft zur Umstellung der Zungen nicht mehr aufbringen kann. Beide Federwippentypen sind bei einem Bruch einer Feder also nicht mehr funktionsfähig und müssen kosten- bzw. zeitaufwendig repariert oder ausgetauscht werden. Des weiteren weist das Antriebsgestänge für den Gabelmittelverschluß Mängel auf, die in erster Linie durch temperaturbedingte Längenänderungen des Antriebsgestänges bei niedrigen bzw. hohen Temperaturen hervorgerufen werden.The problem of the previous hand tamping from the outside of the two sleeper compartment sleepers with drive or tongue test linkage has been largely eliminated through the use of box sleepers both for turnouts on wooden sleepers and for turnouts on concrete sleepers. However, here too, the drive linkage from the tip of the tongue motor to the first clamp or forked closure has the major disadvantages already mentioned. Furthermore, so-called spring rockers are known in the prior art for adjusting the tongues in switches. These are arranged in the sleeper compartment, which means that the two sleepers of a sleeper compartment can only be stuffed on one side and by hand plugs. Neither mechanical nor manual tamping is possible from the inside of the two sleepers of a sleeper compartment. The known spring rockers also have the disadvantage that they have only one or a maximum of two springs. If the single spring breaks, the spring rocker is completely inoperative. The situation is similar with two existing springs and the breakage of one spring, since the only remaining spring can no longer apply the force required to change the tongues. Both spring rocker types are therefore no longer functional if a spring breaks and must be repaired or replaced in a costly or time-consuming manner. Furthermore, the drive linkage for the fork middle lock has defects which are primarily caused by temperature-related changes in length of the drive linkage at low or high temperatures.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zum Umstellen von Zungen in Weichen ohne die eingangs erwähnten Nachteile zu schaffen.The invention has for its object to provide a generic device for switching tongues in switches without the disadvantages mentioned above.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen den Backen¬ schienen/Zungen der Weiche eine mit mindestens vier einstellbaren, Federpaketen ausgebildete Bewegungsvorrichtung angeordnet ist. Die vier Federpakete können je nach Voreinstellung der Federn horizontal eine Druckkraft von 4 x 400 N = 1.600 N erzeugen. Dadurch wird ermöglicht, daß die an einer Backenschiene anliegende Zunge sicher angedrückt und die abliegende Zunge weit genug von einer Backenschiene abgezogen wird. Hierbei wird die erforderliche Mindestrillenweite von 58 mm exakt eingehalten, so daß der Radrücken eines Rades ohne anzufahren, was insbesondere bei hohen Geschwindigkeiten wichtig ist, diesen Rillenbereich passieren kann. Aufgrund der von den vier Federpaketen aufgebrachten hohen Druckkräfte - es besteht auch die Möglichkeit die Bewegungsvorrichtung mit sechs Federpaketen auszustatten - können Gabelmittel- und Klammermittelverschlüsse entfallen.This object is achieved according to the invention in that a movement device designed with at least four adjustable spring assemblies is arranged between the cheek rails / tongues of the switch. Depending on the presetting of the springs, the four spring assemblies can generate a compressive force of 4 x 400 N = 1,600 N horizontally. This makes it possible for the tongue which is in contact with a stock rail to be pressed securely and for the tongue to be pulled off far enough from a stock rail. The required minimum groove width of 58 mm is exactly adhered to, so that the wheel back of a wheel can pass this groove area without starting, which is particularly important at high speeds. Due to the high pressure forces exerted by the four spring assemblies - there is also the option of the movement device with six spring assemblies equip - fork and clamp means locks can be omitted.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Bewegungsvorrich¬ tung als Federwippe ausgebildet ist und in ihrer Mitte ein Tandemfederpaket sowie an ihren linken und rechten Enden jeweils ein Federpaket aufweist. Jedes Federpaket besteht aus einem Federtopf, der die eigentliche, auf einer Druckstange angeordnete Feder aufnimmt. Die Federwippe ist V-förmig ausgebildet. In ihrer Mitte befinden sich zwei nebeneinanderliegende Federpakete; vor allem die Tandemanordnung gewährleistet, daß bei einem Bruch einer der nebeneinanderliegenden Federn die Federwippe weiterhin funktionsfähig bleibt. Die weiterhin an den äußeren Enden der Federwippe angelenkten Federpakete dienen vorrangig zur Erhöhung der aufzubringenden Kräfte. Die Federtöpfe der Federpakete sind vorteilhaft in einem Tragrahmen gelagert, weil sich dieser in einfacher Weise mit einer Schwelle fest verbinden läßt. Die äußeren Enden der Federwippe sind über Schieberstangen mit den Zungen der Weichen verbunden. Die Federwippe wird durch die Bewegung der Zunge mit Hilfe eines Weichenantriebsmotors, der im Bereich der Zungenspitze angeordnet ist, umgestellt.A preferred embodiment of the invention provides that the Bewegungsvorrich¬ device is designed as a spring rocker and has a tandem spring assembly in its center and a spring assembly at its left and right ends. Each spring assembly consists of a spring cup that receives the actual spring, which is arranged on a push rod. The spring rocker is V-shaped. In the middle there are two spring packages lying side by side; Above all, the tandem arrangement ensures that the spring rocker remains functional in the event of a break in one of the adjacent springs. The spring assemblies, which are still articulated on the outer ends of the spring rocker, serve primarily to increase the forces to be applied. The spring cups of the spring assemblies are advantageously mounted in a supporting frame because this can be firmly connected to a threshold in a simple manner. The outer ends of the spring rocker are connected to the tongues of the switches via slide rods. The spring rocker is switched by the movement of the tongue with the help of a switch drive motor, which is arranged in the area of the tongue tip.
Eine weitere Ausgestaltung der Erfindung sieht vor, daß die Schieberstangen Verzah¬ nungen aufweisen. Über diese Verzahnung sind die Zungen verstellbar mit den Schieberstangen verbunden. Dadurch ist es möglich, Fertigungstoleranzen auszu¬ gleichen, insbesondere aber je nach Position der Federwippe in der Zungenvorrichtung bestimmte Rillenweiten und bestimmte Zungenkopfdicken den jeweiligen Verhältnissen, unter anderem auch der Vorspannkraft der Federn, anzupassen.A further embodiment of the invention provides that the slide rods have toothing. The tongues are adjustably connected to the slide rods via this toothing. This makes it possible to compensate for manufacturing tolerances, but in particular, depending on the position of the spring rocker in the tongue device, to adapt certain groove widths and certain tongue head thicknesses to the respective conditions, including the preload force of the springs.
Vorteilhaft wird die erfindungsgemäße Federwippe in einer Kastenschwelle eingebaut. Hierdurch läßt sich ihre Funktionsfähigkeit sehr viel besser aufrechterhalten, weil die Federwippe gegen Umwelteinflüsse geschützt wird und außerdem kann das Stopfen dieser Kastenschwelle automatisch von einer Weichenstopfmaschine vorgenommen werden. Dadurch werden der Unterhaltungsaufwand und die Störanfälligkeit der Weiche wesentlich reduziert.The spring rocker according to the invention is advantageously installed in a box sleeper. As a result, their functionality can be maintained much better because the spring rocker is protected against environmental influences and, in addition, the tamping of this box threshold can be carried out automatically by a switch tamping machine. This reduces the maintenance effort and the susceptibility to failure of the Switch significantly reduced.
Zur Überwachung der beiden Zungen lassen sich zwei einfache mechanische Zungenprüfer einsetzen, da die ansonsten erforderliche signaltechnische Überwachung des Antriebsgestänges eines notwendigen Gabelmittelverschlusses entfällt.Two simple mechanical tongue testers can be used to monitor the two tongues, since the otherwise necessary signaling monitoring of the drive linkage of a necessary fork means lock is omitted.

In Fig. 1 ist eine in einer Kastenschwelle 2 angeordnete Weichenstellvorrichtung 1 dargestellt. Die zwei Backenschienen 3, 4 sind mit der Kastenschwelle 2 verspannt. In der Mitte der Kastenschwelle 2 ist eine Bewegungsvorrichtung in Form einer Feder¬ wippe 5 angeordnet. Die Federwippe 5 besteht aus einem im Profil V-förmigen Grund-Tragelement 6, das mittig zwei nebeneinanderliegende, über Druckstangen 7 beweglich angeordnete Federpakete 8, 9 in Tandemanordnung (vgl. hierzu Fig. 2) aufweist, während äußere Federpakete 12, 13 an den Enden 10, 11 des V-förmigen Tragelementes 6 mit ihren Druckstangen 7 angeordnet sind. Die Federtöpfe 14 der Federn 8. 9 und 12, 13 sind um ihre horizontale Achse 15 drehbar in einem Tragrahmen 16 gelagert, der mit dem Boden 17 der Kastenschwelle 2 verschaubt ist (vgl. hierzu die Fig. 3 und 4). Die Druckkraft der Federpakete 8, 9 und 12, 13 ist über eine Einstellmutter 18 stufenlos zwischen 50 N und 400 N einstellbar. An den äußeren Enden 10, 11 der Federwippe 5 sind mittels einer Schrauben-Mutternkombination 19 weiterhin Schieberstangen 20, 21 befestigt. Die von der Federwippe 5 entfernten, anderen Enden 22, 23 der Schieberstangen 20, 21 sind über Druckstücke 24, 25 mit Zungenkloben 26, 27 mit einer jeweils an der Backenschiene 3 anliegenden Zunge 28 und einer jeweils von der Backenschiene 4 abgezogenen Zunge 29 verbunden.In Fig. 1 a switch device 1 arranged in a box sleeper 2 is shown. The two stock rails 3, 4 are braced with the box sleeper 2. A movement device in the form of a spring rocker 5 is arranged in the middle of the box sleeper 2. The spring rocker 5 consists of a V-shaped profile Basic supporting element 6, which has two spring assemblies 8, 9 in tandem arrangement (see FIG. 2), which are arranged in the center in the middle and moveable via push rods 7, while outer spring assemblies 12, 13 have ends 10, 11 of the V-shaped supporting element 6 their push rods 7 are arranged. The spring cups 14 of the springs 8, 9 and 12, 13 are rotatably mounted about their horizontal axis 15 in a support frame 16 which is screwed to the floor 17 of the box sleeper 2 (cf. FIGS. 3 and 4). The pressure force of the spring assemblies 8, 9 and 12, 13 can be adjusted continuously between 50 N and 400 N via an adjusting nut 18. At the outer ends 10, 11 of the spring rocker 5, slide rods 20, 21 are further fastened by means of a screw-nut combination 19. The other ends 22, 23 of the slide rods 20, 21, which are removed from the spring rocker 5, are connected via pressure pieces 24, 25 with tongue clamps 26, 27 to a tongue 28 each resting on the stock rail 3 and a tongue 29 each pulled off the stock rail 4.
Die Schieberstangen 20, 21 weisen im Bereich der Druckstücke 24, 25 jeweils eine Verzahnung 30, 31 auf, über die die Zungenkloben 26, 27 auf den Schieberstangen 20, 21 rasterförmig verstellbar sind. Dies erfolgt durch Lösen und Abheben der Druckstücke, um sie an anderer Stelle wieder auf die Schieberstange aufzusetzen und zu befestigen. Dadurch ist es möglich, je nach Position der Federwippe 5 in der Weichenvorrichtung 1 bestimmte Rillenweiten einzuhalten, aber auch bestimmte Zungenkopfdicken an die jeweiligen Verhältnisse, wie die Vorspannkraft der Federpakete 8, 9 und 12, 13, anzupassen.The slide rods 20, 21 each have teeth 30, 31 in the area of the pressure pieces 24, 25, by means of which the tongue blocks 26, 27 on the slide rods 20, 21 can be adjusted in a grid pattern. This is done by loosening and lifting the pressure pieces in order to put them back on the slide rod and fasten them elsewhere. This makes it possible, depending on the position of the spring rocker 5 in the switch device 1, to maintain certain groove widths, but also to adapt certain tongue head thicknesses to the respective conditions, such as the pretensioning force of the spring assemblies 8, 9 and 12, 13.
Am linken Kopfende 32 der Kastenschwelle 2 ist ein Normzungenprüfer 33 angeordnet, der aber je nach räumlicher Gegebenheit auch rechts vor Kopf der Kastenschwelle 2 - wie in den Fig. 1, 2 alternativ strichpunktiert dargestellt - angeordnet werden kann. Der Zungenprüfer 33 ist über zwei Schwellentrageisen 34, 35 mit Obergurten 36, 37 der Kastenschwelle 2 starr verbunden, und zwei Zungenprüfstangen 38, 39 stellen eine mechanische Verbindung vom Zungenprüfer 33 zu den beiden Zungen 28, 29 her (vgl. hierzu auch Fig. 2). Damit wird die signaltechnische Überwachung der beiden Zungen 28, 29 sicher gewährleistet. Anhand der Fig. 5a bis 5d wird nachfolgend eine Verstellung der Zungen 28, 29 mittels der Federwippe 5 näher erläutert.At the left head end 32 of the box sleeper 2 there is a standard tongue tester 33 which, depending on the spatial situation, can also be arranged on the right in front of the head of the box sleeper 2 - as shown alternatively by dash-dotted lines in FIGS. 1, 2. The tongue tester 33 is rigidly connected to the upper straps 36, 37 of the box sleeper 2 by means of two tie-bars 34, 35, and two tongue test bars 38, 39 establish a mechanical connection from the tongue tester 33 to the two tongues 28, 29 (cf. also FIG. 2 ). The signal-technical monitoring of the two tongues 28, 29 is thus reliably ensured. 5a to 5d, an adjustment of the tongues 28, 29 by means of the spring rocker 5 is explained in more detail below.
In Fig. 5a ist die linke anliegende Zunge 28 an die Backenschiene 3 angedrückt und die rechte abliegende Zunge 29 so weit von der Backenschiene 4 abgezogen, daß die geforderte Mindestrillenweite von 58 mm erreicht wird. Dadurch ist es möglich, daß der Radrücken eines Rades eines Schienenfahrzeuges ohne die Anschtagseite der Zunge zu berühren, was insbesondere bei hohen Geschwindigkeiten sehr wichtig ist, diesen Rillenbereich 40 passieren kann.In Fig. 5a, the left-lying tongue 28 is pressed against the stock rail 3 and the right-lying tongue 29 is pulled so far from the stock rail 4 that the required minimum groove width of 58 mm is reached. This makes it possible for the wheel back of a wheel of a rail vehicle to touch the groove side 40 of the tongue without the contact side of the tongue, which is very important, particularly at high speeds.
Durch eine Bewegung der mit der Federwippe 5 gekoppelten Zungen 28, 29, mit Hilfe eines Weichenantriebsmotors, der im Bereich der hier nicht dargestellten Zungenspitze angeordnet ist, wird die Umstellung eingeleitet. Wie die Fig. 5b zeigt, bewegt sich bei einer Umstellung der Zungen 28, 29 zunächst die abliegende Zunge 29 in Richtung der Backenschiene 4, und zeitversetzt kommt damit die an der anderen Backenschiene 3 anliegende Zunge 28 gegen die Federkraft frei. Dieses Freikommen setzt etwa dann ein, wenn die abliegende Zunge 29 mit der Federwippe 5 einen Weg gemäß Doppelpfeil 41 zur Backenschiene 4 hin zurückgelegt hat. Ab diesem Zeitpunkt wird die Zunge 28 von der Backenschiene 3 abgezogen, und in der Folge findet die Zunge 29 ihre Anlage an der Backenschiene 4, wie in Figur 5c dargestellt.The change is initiated by a movement of the tongues 28, 29 coupled to the spring rocker 5 with the aid of a switch drive motor which is arranged in the region of the tongue tip (not shown here). As FIG. 5b shows, when the tongues 28, 29 are moved, the remote tongue 29 first moves in the direction of the stock rail 4, and with a time delay the tab 28 resting on the other stock rail 3 is released against the spring force. This release occurs approximately when the remote tongue 29 has covered a path according to the double arrow 41 to the stock rail 4 with the spring rocker 5. From this point in time, the tongue 28 is pulled off the stock rail 3, and subsequently the tongue 29 abuts the stock rail 4, as shown in FIG. 5c.
In Figur 5d wird gezeigt, wie die Federpakete 8, 9 und 12, 13 vollständig umgeschlagen sind und somit einerseits die Zunge 29 mit einer mit einem Klammerverschluß vergleichbaren Kraft gegen die Backenschiene 4 pressen und andererseits die Zunge 28 um mindestens 58 mm von der linken Backenschiene 3 wegziehen und dort sicher in der Position halten. In FIG. 5d it is shown how the spring assemblies 8, 9 and 12, 13 are completely turned over and thus on the one hand press the tongue 29 with a force comparable to a clamp closure against the stock rail 4 and on the other hand the tongue 28 by at least 58 mm from the left stock rail 3 pull away and hold securely in position.
