Definitions
- the invention relates to a device for moving a tongue rail of a switch, with at least two rollers arranged one behind the other, arranged essentially parallel to the rail course, on which the tongue rail can roll onto the first roller from a lower resting position on the stock rail and directly in front of the first roller can roll on the other roles until it reaches a remote position.
- the object of the present invention is thus to overcome the problems described and to provide a device for moving a tongue rail of a switch which, while at the same time being as robust as possible, ensures the smoothest possible movement of the tongue rail, in particular prevents the tongue rails from sinking, and which so little during use as much as possible in order to achieve the longest possible, low-maintenance use.
- At least one further intermediate roller which is smaller than the rollers, is provided in the space between two adjacent rollers, the axis of rotation being arranged essentially parallel to the axes of rotation of the rollers.
- the reel size of the reels can be chosen to be large enough to allow the reel to be rolled up as easily and with as little friction as possible without running the risk of the tongue rail sitting between the reels.
- the linear structure also makes the device more compact and less complex, since the holding devices for the rollers can be combined.
- the rollers and intermediate rollers can be arranged in different positions relative to one another. So the highest points of the coats of the rollers and the intermediate rollers can be at the same height in order to enable the tongue rail to roll as easily as possible. However, it can be particularly advantageous to arrange the intermediate rollers relative to the rollers in such a way that the highest point of a jacket of the intermediate rollers is slightly below the highest points of the jacket of the rollers. This can be of particular importance if the rollers have different designs and the resulting different elasticities.
- rollers particularly preferably the first roller
- the suspension reduces wear on the rollers and the tongue rail, at the same time the suspension provides an elastomer layer represents a mechanical solution that is as compact as possible and less prone to errors and requires little maintenance.
- Such an elastomer suspension can be realized, for example, by a roller that has a hub made of preferably less elastic, stable material, hence an inner elastomer layer and an outer thin metal layer. The latter metal layer prevents damage to the elastomer layer by rolling it up or rolling it over the roller or intermediate roller.
- all or parts of the rollers and intermediate rollers can also be produced from other materials or entirely from metal.
- the rollers as elastomer-sprung rollers and providing the intermediate rollers made of less elastic material, for example steel. This makes it easy to roll it up and allows it to move along the rollers smoothly.
- the intermediate rollers do not form a roller plane of the same height with the rollers, but are slightly offset relative to them. Because even if the elastomer-sprung rollers are slightly deformed on them during the rolling of the tongue rail, there is no undesired easy rolling up on the intermediate rollers, which could lead to material wear.
- the tongue rail is slightly lowered when rolling on the intermediate rollers, but this does no harm, since it is easy to roll up onto the next elastomer-sprung roller because of the small height difference.
- rollers and intermediate rollers or at least parts of them are arranged on a common holding device, this has advantages in particular with regard to the easy manufacture of the device segments.
- the mechanical stability of the roller system is particularly well secured.
- the holding device consists of two laterally arranged parts, between which the rollers can be attached. This compact and simple, cost-saving design reveals a particularly inexpensive and less error-prone solution.
- the device can easily be adapted to the conditions on site or, if necessary, easily readjusted. This is particularly important because the height of the rollers has to be optimized. On the one hand, they should be somewhat higher relative to the contact surface on which the tongue rail rests in the lying position in order to prevent friction during rolling. On the other hand, it is advantageous to keep the described height difference between the roller plane and the support surface small, so that rolling onto the first roller is easily possible.
- the solution to arrange the rollers and intermediate rollers on a common holding device, which is adjustable in height, is particularly advantageous. This makes it possible to set the intermediate roller together with the setting of the other rollers, which results in a particularly simple to use and easily adjustable solution.
- the device can be attached to the switch in a variety of ways depending on the particular situation. Particularly noteworthy are the possibilities of attaching the device between two sleepers or attaching it to the stock rail.
- Fig. 1 discloses an embodiment which is arranged between two sleepers, not shown, and is attached to them.
- four leaf springs 6 are attached to the sides of a carrier body 5, which can be fastened to the sleepers in fastening shoes (not shown).
- the device can be moved between the sleepers along an axis parallel to the sleepers.
- the device is brought close to the tongue rail and fastened by this displacement during installation, so that the tongue rail lies directly on the jacket of the first roller 1.
- Fastening methods are already known how EP 0 654 561 A1 disclosed.
- the rollers 1a, 1b and the intermediate roller 2 are arranged such that their axes of rotation run parallel.
- the diameter of the rollers 1a, 1b is chosen so large that it is easy to roll up a tongue rail from the resting position.
- the diameter of the intermediate roller 2 is in any case smaller than half the diameter of the rollers 1a, 1b, in the case shown it is approximately a quarter of the diameter of the rollers 1a, 1b.
- the rollers 1a, 1b and the intermediate roller 2 are arranged very close to one another in order to avoid a possible sinking between the rollers 1a, 1b and the intermediate roller 2 even with a particularly narrow foot width.
- adjustment devices 4 are provided, by means of which the height of the axes of the rollers 1a, 1b can be set individually.
- the intermediate roller 2 does not have to be adjusted separately, but is also adjusted by the common holding device 3 with the rollers 1a, 1b.
- the rollers 1a, 1b and the intermediate roller 2 are arranged such that the highest points 1ah, 1bh, 2h of the shells of the rollers 1a, 1b and the intermediate roller 2 are approximately in a horizontal plane E in cross section. If necessary, the highest point 2h of the jacket of the intermediate roller 2 lies slightly below this plane E, namely by the extent of the possible deformation of the first roller 1a.
- the plane E lies slightly above the upper edge of the carrier body 5.
- Fig. 2 discloses an inner segment of the in Fig. 1 described embodiment. It shows that the holding element 3 consists of two opposing metal elements, each having three bores 3a ', 3a ", 3b.
- the axes 20 of the rollers 1a, 1b run through two large bores 3a', 3a", centrally in the upper part through a smaller bore 3b the axis 2c of the intermediate roller 2.
- This intermediate roller 2 consists of an outer jacket 2a, two middle sleeves 2b ', 2b “and an axis 2c.
- the individual elements 2a, 2b", 2b “and 2c are inserted into each other and thus result in the intermediate roller 2.
- the axes of the rollers 1a, 1b have fastening elements 1aa, 1bb outside the roller 1a, 1b which have bores in order to be able to be optimally connected to the adjusting device 4.
- Fig. 3 shows a side view of the embodiment of FIG Fig. 1 and Fig. 2 . It can be seen that the highest point of the shells of the rollers 1a, 1b is level with the highest point of the sheath of the intermediate roller 2. Furthermore, it can be seen that the rollers 1a, 1b protrude from the carrier body 5 below the carrier body 5. This is a particularly simple and inexpensive construction. However, it can also be advantageous to design the carrier body 5 in such a way that it encloses the rollers 1a, 1b on the underside, since it is thus not necessary to ensure that there is sufficient space for the rollers 1a, 1b under the device.
- Fig. 4 shows an exploded view of a spring roller. Rollers 1a, 1b of this type can be particularly advantageous if on as in Fig. 1 described leaf springs 6 is dispensed with.
- the spring roller shown has an outermost jacket 11.
- the outermost jacket 11 can be made of sturdy metal to prevent wear by rolling up the tongue rail. However, it can also be made of elastic material to allow additional damping.
- a fastening ring 14 and two limiting elements 15 are arranged within the spring element 13.
- the limiting elements 15 are arranged on a hollow axis 17 which rests on the axis 20. Distal to the delimiting elements 15, further safety rings 16, as well as a disk 18 and a toothed disk 19 are arranged.

Description
Die Erfindung betrifft eine Vorrichtung zum Bewegen einer Zungenschiene einer Weiche, mit mindestens zwei hintereinander gereihten, zum Schienenverlauf im Wesentlichen parallel angeordneten Rollen, auf welchen die Zungenschiene von einer unteren Anliegeposition an der Backenschiene und direkt vor der ersten Rolle auf die erste Rolle aufrollen kann und auf die weiteren Rollen weiterrollen kann, bis sie eine abliegende Position erreicht.The invention relates to a device for moving a tongue rail of a switch, with at least two rollers arranged one behind the other, arranged essentially parallel to the rail course, on which the tongue rail can roll onto the first roller from a lower resting position on the stock rail and directly in front of the first roller can roll on the other roles until it reaches a remote position.
Vorrichtungen zum Bewegen von Zungenschienen von Weichen müssen die Zungenschiene bei Stellen der Weiche ausreichend weit transportieren können, um ein sicheres Überfahren durch ein Schienenfahrzeug zu ermöglichen. Das Bewegen der Zungenschiene muss aber so reibungsarm wie möglich vorgenommen werden, um unnötigen Verschleiß zu verhindern. Gleichzeitig wirken große Kräfte auf die Schienen bei Überfahren von schweren Fahrzeugen, weshalb auf eine möglichst robuste Bauweise der Weiche insgesamt und insbesondere einer Vorrichtung zum Bewegen von Zungenschienen zu achten ist. Aus diesem Grund wurden Systeme bereits entwickelt, welche Rollenanordnungen besitzen, die ein Aufrollen der Zungenschiene aus der an der Backenschiene anliegenden unteren Anliegeposition bedingen, wodurch sie auf den Rollen von der Backenschiene weg transportiert werden kann.Devices for moving the tongue rails of turnouts must be able to transport the tongue rail sufficiently far at points of the turnout in order to enable a rail vehicle to pass over it safely. However, the tongue rail must be moved with as little friction as possible to prevent unnecessary wear. At the same time, large forces act on the rails when driving over heavy vehicles, which is why the switch as a whole as robust as possible and in particular a device for moving tongue rails must be ensured. For this reason, systems have already been developed which have roller arrangements which require the tongue rail to be rolled up from the lower contact position lying against the stock rail, as a result of which it can be transported away from the stock rail on the rollers.
Aus der
Ein weiteres Problem bereits bekannter Lösungen ist das sichere Transportieren der Zungenschiene, auch bei geringer Fußbreite derselben. Wenn das Profil der Zungenschiene sehr schmal ausgestaltet ist, wie zum Beispiel bei Schienen nach dem amerikanischen AREMA-Standard, kann die Schiene zwischen den Rollen absinken, an der Oberfläche reiben und damit unerwünschten Verschleiß und Störungen bedingen.Another problem of already known solutions is the safe transport of the tongue rail, even with the same narrow foot width. If the profile of the tongue rail is very narrow, as is the case, for example, with rails according to the American AREMA standard, the rail can sink between the rollers, rub against the surface and thus cause undesired wear and malfunctions.
Aus der
Aufgabe der vorliegenden Erfindung ist somit die beschriebenen Probleme zu überwinden und eine Vorrichtung zum Bewegen einer Zungenschiene einer Weiche bereitzustellen, die bei gleichzeitig möglichst robuster Bauweise eine möglichst reibungslose Bewegung der Zungenschiene sicherstellt, insbesondere das Absinken der Zungenschienen verhindert, und die während ihrer Verwendung so wenig wie möglich belastet wird, um eine möglichst lange und wartungsarme Verwendungsdauer zu erreichen.The object of the present invention is thus to overcome the problems described and to provide a device for moving a tongue rail of a switch which, while at the same time being as robust as possible, ensures the smoothest possible movement of the tongue rail, in particular prevents the tongue rails from sinking, and which so little during use as much as possible in order to achieve the longest possible, low-maintenance use.
Dies wird erfindungsgemäß dadurch gelöst, dass mindestens eine weitere im Vergleich zu den Rollen kleinere Zwischenrolle im Raum zwischen jeweils zwei benachbarten Rollen vorgesehen ist, wobei die Drehachse im Wesentlichen parallel zu den Drehachsen der Rollen angeordnet ist.This is achieved according to the invention in that at least one further intermediate roller, which is smaller than the rollers, is provided in the space between two adjacent rollers, the axis of rotation being arranged essentially parallel to the axes of rotation of the rollers.
Durch das Einbringen kleinerer Zwischenrollen zwischen die Rollen wird einerseits verhindert, dass unnötige Belastungen durch Drehmomente auf die Vorrichtung wirken. Andererseits kann die Rollengröße der Rollen so groß gewählt werden, dass ein möglichst leichtes und reibungsarmes Aufrollen möglich ist, ohne Gefahr zu laufen, dass die Zungenschiene zwischen den Rollen aufsitzt. Durch den linearen Aufbau wird außerdem die Vorrichtung kompakter und weniger aufwändig, da die Haltevorrichtungen für die Rollen zusammengefasst werden kann.By introducing smaller intermediate rollers between the rollers, on the one hand, unnecessary loads caused by torques are prevented from acting on the device. On the other hand, the reel size of the reels can be chosen to be large enough to allow the reel to be rolled up as easily and with as little friction as possible without running the risk of the tongue rail sitting between the reels. The linear structure also makes the device more compact and less complex, since the holding devices for the rollers can be combined.
Die Rollen und Zwischenrollen können in unterschiedlichen Positionen relativ zueinander angeordnet sein. So können die höchsten Punkte der Mäntel der Rollen und der Zwischenrollen auf gleicher Höhe stehen, um ein möglichste leichtes Rollen der Zungenschiene zu ermöglichen. Besonders vorteilhaft kann es aber sein, die Zwischenrollen relativ zu den Rollen so anzuordnen, dass der höchste Punkt eines Mantels der Zwischenrollen etwas unter den höchsten Punkten von Mänteln der Rollen liegt. Dies kann insbesondere dann von Wichtigkeit sein, wenn die Rollen unterschiedliche Bauarten und daraus bedingte unterschiedliche Elastizitäten aufweisen.The rollers and intermediate rollers can be arranged in different positions relative to one another. So the highest points of the coats of the rollers and the intermediate rollers can be at the same height in order to enable the tongue rail to roll as easily as possible. However, it can be particularly advantageous to arrange the intermediate rollers relative to the rollers in such a way that the highest point of a jacket of the intermediate rollers is slightly below the highest points of the jacket of the rollers. This can be of particular importance if the rollers have different designs and the resulting different elasticities.
Wenn die Rollen, besonders vorzugsweise die erste Rolle als elastomergefederte Rollen ausgeführt sind, wird dadurch die Bewegung der Zungenschiene auf den Rollen und auch das Aufrollen optimiert. Durch die Federung wird die Abnutzung der Rollen und der Zungenschiene vermindert, gleichzeitig stellt die Federung durch eine Elastomerschicht eine möglichst kompakte und wenig fehleranfällige und wartungsarme mechanische Lösung dar. Eine solche Elastomerfederung kann beispielsweise durch eine Rolle realisiert werden, welche eine Nabe aus vorzugsweise wenig elastischem, stabilem Material besitzt, darum eine innere Elastomerschicht und eine äußere dünne Metallschicht. Letztere Metallschicht verhindert das Beschädigen der Elastomerschicht durch das Aufrollen auf oder das Rollen über die Rolle bzw. Zwischenrolle. Es können aber auch alle oder Teile der Rollen und Zwischenrollen aus anderen Materialien oder ganz aus Metall hergestellt werden.If the rollers, particularly preferably the first roller, are designed as elastomer-sprung rollers, the movement of the tongue rail on the rollers and also the rolling up are thereby optimized. The suspension reduces wear on the rollers and the tongue rail, at the same time the suspension provides an elastomer layer represents a mechanical solution that is as compact as possible and less prone to errors and requires little maintenance. Such an elastomer suspension can be realized, for example, by a roller that has a hub made of preferably less elastic, stable material, hence an inner elastomer layer and an outer thin metal layer. The latter metal layer prevents damage to the elastomer layer by rolling it up or rolling it over the roller or intermediate roller. However, all or parts of the rollers and intermediate rollers can also be produced from other materials or entirely from metal.
Besonders hervorzuheben ist die Möglichkeit, die Rollen als elastomergefederte Rollen auszuführen, und die Zwischenrollen aus wenig elastischem Material, beispielsweise Stahl, bereitzustellen. Dadurch ist ein leichtes Aufrollen, und die Fortbewegung entlang der Rollen reibungslos möglich. Insbesondere, wenn die Zwischenrollen wie oben beschrieben nicht mit den Rollen eine Rollebene gleicher Höhe bilden, sondern ihnen gegenüber leicht nach unten versetzt sind, ist dies vorteilhaft. Denn auch wenn die elastomergefederten Rollen während des Rollens der Zungenschiene auf ihnen leicht deformiert sind, so kommt es nicht zu einem unerwünschten leichten Aufrollen auf die Zwischenrollen, was zu Materialverschleiß führen könnte. Die Zungenschiene wird zwar beim Rollen auf den Zwischenrollen leicht abgesenkt, dies schadet allerdings nicht, da das leichte Aufrollen auf die nächste elastomergefederte Rolle wegen der geringen Höhendifferenz leicht möglich ist.Particularly noteworthy is the possibility of designing the rollers as elastomer-sprung rollers and providing the intermediate rollers made of less elastic material, for example steel. This makes it easy to roll it up and allows it to move along the rollers smoothly. This is advantageous in particular if the intermediate rollers, as described above, do not form a roller plane of the same height with the rollers, but are slightly offset relative to them. Because even if the elastomer-sprung rollers are slightly deformed on them during the rolling of the tongue rail, there is no undesired easy rolling up on the intermediate rollers, which could lead to material wear. The tongue rail is slightly lowered when rolling on the intermediate rollers, but this does no harm, since it is easy to roll up onto the next elastomer-sprung roller because of the small height difference.
Werden Rollen und Zwischenrollen oder zumindest Teile von ihnen auf einer gemeinsamen Haltevorrichtung angeordnet, so hat dies Vorteile insbesondere in Bezug auf die leichte Herstellung der Vorrichtungssegmente. Außerdem ist dadurch die mechanische Stabilität des Rollensystems besonders gut gesichert. Vorteilhaft ist weiters, wenn die Haltevorrichtung aus zwei seitlich angeordneten Teilen besteht, zwischen welchen die Rollen angebracht werden können. Durch diese kompakte und einfache, kostensparende Bauweise wird eine besonders günstige und wenig fehleranfällige Lösung offenbart.If rollers and intermediate rollers or at least parts of them are arranged on a common holding device, this has advantages in particular with regard to the easy manufacture of the device segments. In addition, the mechanical stability of the roller system is particularly well secured. It is also advantageous if the holding device consists of two laterally arranged parts, between which the rollers can be attached. This compact and simple, cost-saving design reveals a particularly inexpensive and less error-prone solution.
Werden die Rollen zumindest teilweise höhenverstellbar ausgeführt, so kann leicht die Vorrichtung vor Ort an die Begebenheiten angepasst oder falls notwendig leicht neu eingestellt werden. Dies ist insbesondere deswegen wichtig, da die Höhe der Rollen optimiert werden muss. Einerseits sollten sie relativ zur Auflagefläche, an der die Zungenschiene in Anliegeposition aufliegt, etwas höher liegen, um die Reibung während des Rollens zu verhindern. Andererseits ist es vorteilhaft die beschriebene Höhendifferenz zwischen Rollebene und Auflagefläche klein zu halten, damit das Aufrollen auf die erste Rolle leicht möglich ist.If the rollers are at least partially height-adjustable, the device can easily be adapted to the conditions on site or, if necessary, easily readjusted. This is particularly important because the height of the rollers has to be optimized. On the one hand, they should be somewhat higher relative to the contact surface on which the tongue rail rests in the lying position in order to prevent friction during rolling. On the other hand, it is advantageous to keep the described height difference between the roller plane and the support surface small, so that rolling onto the first roller is easily possible.
Als besonders vorteilig ist die Lösung hervorzuheben, die Rollen und Zwischenrollen an einer gemeinsamen Haltevorrichtung anzuordnen, welche höhenverstellbar ist. Dadurch ist es möglich die Zwischenrolle zusammen mit der Einstellung der anderen Rollen einstellen zu können, wodurch sich eine besonders einfach zu verwendende und leicht einstellbare Lösung ergibt.The solution to arrange the rollers and intermediate rollers on a common holding device, which is adjustable in height, is particularly advantageous. This makes it possible to set the intermediate roller together with the setting of the other rollers, which results in a particularly simple to use and easily adjustable solution.
Die Vorrichtung kann auf unterschiedlichste Weise an die Weiche abhängig von der jeweiligen Situation angebracht sein. Besonders hervorzuheben sind die Möglichkeiten, die Vorrichtung zwischen zwei Schwellen zu befestigen, bzw. sie an der Backenschiene anzubringen.The device can be attached to the switch in a variety of ways depending on the particular situation. Particularly noteworthy are the possibilities of attaching the device between two sleepers or attaching it to the stock rail.
Abhängig von der Distanz, die die Zungenschiene zur Backenschiene in der nichtanliegenden Position erreichen muss, kann es vorteilhaft sein nach der letzten Rolle distal der Backenschiene eine weitere Zwischenrolle anzuordnen, um die maximal erreichbare Rolldistanz weiter zu erhöhen.Depending on the distance that the tongue rail must reach from the stock rail in the non-contact position, it may be advantageous to arrange a further intermediate roll after the last roll distal to the stock rail in order to further increase the maximum rolling distance that can be achieved.
