Description
Die Erfindung bezieht sich auf eine Querschwelle für Eisenbahngleise, insbesondere im Bereich der Stellantriebe und Verschlüsse von Weichen, mit einem im wesentlichen trogartigen nach oben offenen Profil aus Stahl, wobei an die freien Enden der Seitenwände des trogartigen Profils Trägerflansche angeschlossen sind.The invention relates to a sleepers for railway tracks, especially in the field of actuators and closures of switches, with a substantially trough-like open-topped profile made of steel, wherein carrier flanges are connected to the free ends of the side walls of the trough-like profile.
Aus der DE 43 15 200 A1 und der US-A-1358536 ist bereits eine Querschwelle bekannt geworden, bei der ein oben offenes kastenförmiges Schwellenprofil aus Stahl mit seitwärts auskragenden Trägerflanschen mit seitlichen Versteifungselementen versehen wurde, um Verformungen der Schwelle unter rollender Last gering zu halten. An den jeweils auskragenden Trägerflanschen sind bei der DE 43 15 200 A1 jeweils gesonderte Rippenplatten für die Befestigung der Backenschiene und Gleitstühle für das Aufliegen einer Zungenschiene vorgesehen.From DE 43 15 200 A1 and US-A-1358536 a cross sleeper is already known, in which an open-topped box-shaped threshold profile made of steel was provided with laterally projecting support flanges with lateral stiffening elements to keep deformations of the threshold under rolling load low , At the respective projecting support flanges 43 15 200 A1 each separate ribbed plates are provided for the attachment of the stock rail and sliding chairs for resting a tongue rail in DE.
Die US-A-850876 zeigt eine Trogschwelle mit einer die einwärts ragenden Trägerflansche und die Seitenwände teilweise übergreifenden Unterlagsplatte.US-A-850876 shows a trough sleeper with a backing plate which projects inwardly and partially overlaps the sidewalls.
Aus der AT 001 019 U1 ist weiters bereits eine Querschwelle für Eisenbahngleise der eingangs genannten Art bekannt geworden, bei welchen die aufwärts ragenden Seitenwände des trogartigen Profils über einen Teil ihrer Höhe einen spitzen Winkel mit der Bodenplatte einschließen, um auf diese Weise ein besseres elastisches Verhalten bei Biege-Wechselbeanspruchungen durch die rollende Last zu erzielen. Auch bei dieser Ausbildung wurden im Bereich der Seitenwände und der seitlichen auskragenden Trägerflanschen Versteifungselemente angeordnet.From AT 001 019 U1 a cross-sleeper for railway tracks of the type mentioned is also already known, in which the upwardly projecting side walls of the trough-like profile over part of their height include an acute angle with the bottom plate, in order to achieve a better elastic behavior to achieve alternating bending stresses due to the rolling load. In this embodiment, stiffening elements were arranged in the region of the side walls and the side projecting support flanges.
Die Erfindung geht nun von der eingangs genannten Querschwelle aus und zielt darauf ab, seitlich auskragende und vorragende Versteifungselemente zu vermeiden, um die Festigkeitseigenschaften und insbesondere die Aufnahme von hohen dynamischen Kräften zu verbessern und dennoch den für die Anordnung von Teilen eines Weichenantriebes oder von Verschlussvorrichtungen erforderlichen Freiraum zu gewährleisten. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Querschwelle im wesentlichen darin, dass die Trägerflansche zueinander gerichtet einwärts angeordnet sind und mit sich über die lichte Weite zwischen den Trägerflanschen quer zur Schwellenlängsrichtung erstreckenden Rippenplatten verbunden, insbesondere verschraubt sind, wobei die Rippenplatten im wesentlichen U-förmigen Umriss aufweisen und im Bereich ihrer in Schwellenlängsrichtung verlaufenden Schenkel Gleitstühle tragen. Dadurch, dass die Trägerflansche über diese Trägerflansche miteinander verbindende sich quer über die lichte Weite zwischen den Trägerflanschen erstreckende Rippenplatten verbunden, und insbesondere verschraubt sind, wird eine wesentliche Erhöhung der Festigkeit erzielt, da nunmehr in diesem Bereich ein geschlossenes Kastenprofil ausgebildet wird, welches sich durch wesentlich höhere Formstabilität auszeichnet. Gleichzeitig kann durch derartige die Trägerflansche miteinander verbindende Rippenplatten bei schwingender Belastung durch rollende Last eine ausschließlich vertikale Belastung sichergestellt werden, sodass keine horizontalen dynamischen Kräfte auf die Schraubverbindungen wirksam werden und daher der Gefahr eines Bruches von Schrauben oder einer Abscherung von Schrauben wirkungsvoll entgegengewirkt wird. Die Rippenplatte bilden gleichzeitig eine sichere planparallele Verbindung mit den Trägerlaschen der Querschwelle aus, wobei gleichzeitig der Vorteil erreicht wird, dass seitlich vorragende Versteifungselemente, welche beispielsweise bei einem Stopfen der Gleisbettung bzw. des Gleisschotters hinderlich wären, vermieden werden können. Zur Vermeidung von Belastungsspitzen im trogartigen Profil ist die Ausbildung in bevorzugter Weise derart weitergebildet, dass die freien Enden der Seitenwände des trogartigen Profils in einem Teilbereich der Auflage der Rippenplatten Lastverteilungselemente, insbesondere umgreifende Bügel, tragen. Derartige Lastverteilungselemente können im Bereich der Schienenauflage angeordnet werden und versteifen die Seitenwände des trogartigen Profils in einer Weise, dass die im Bereich der Schienenauf lage entstehenden Kräfte auf eine größere Fläche verteilt werden. Dadurch wird die Stabilität des Profils weiter erhöht.The invention is now based on the above-mentioned crossbar and aims to avoid laterally projecting and projecting stiffening elements to the strength properties and in particular to improve the uptake of high dynamic forces while still providing the space required for the placement of parts of a point machine or closure devices. To achieve this object, the cross sleeper according to the invention essentially consists in that the support flanges are arranged facing each other inwardly and connected to the clear width between the support flanges transverse to the threshold longitudinal direction extending ribbed plates, in particular screwed, wherein the ribbed plates are substantially U-shaped outline have and wear in the region of their running in the threshold longitudinal leg sliders. Due to the fact that the carrier flanges are connected to each other via these carrier flanges connecting ribbed plates extending transversely across the clear width between the carrier flanges, and in particular are screwed, a substantial increase in strength is achieved, since now a closed box profile is formed in this region, which is formed by significantly higher dimensional stability distinguishes. At the same time can be ensured by such the carrier flanges interconnecting rib plates under swinging load by rolling load exclusively vertical load, so that no horizontal dynamic forces acting on the screw and therefore the risk of breakage of screws or a shearing of screws is effectively counteracted. At the same time, the ribbed plate forms a secure plane-parallel connection with the carrier straps of the transverse sleeper, while at the same time achieving the advantage that laterally projecting stiffening elements, which would be an obstacle, for example, in the case of a plug of the track bedding or of the track ballast, can be avoided. To avoid load peaks in trough-like profile training is preferably further developed such that the free ends of the side walls of the trough-like profile in a portion of the support of the rib plates load distribution elements, in particular encompassing strap wear. Such load distribution elements can be arranged in the region of the rail support and stiffen the Side walls of the trough-like profile in such a way that the forces arising in the region of the Schienenauf are distributed over a larger area. This further increases the stability of the profile.
Die erfindungsgemäße Ausbildung ist so getroffen, dass die Rippenplatten im Wesentlichen U-förmigen Umriss aufweisen und im Bereich ihrer in Schwellenlängsrichtung verlaufenden Schenkel Gleitstühle tragen. Eine derartige im wesentlichen U-förmigen Umriss aufweisende Rippenplatte erlaubt es an den beiden Schenkeln der Rippenplatte Gleitstühle anzuordnen, sodass mit einem einzigen Bauteil, nämlich der im wesentlichen U-förmigen Umriss aufweisenden Rippenplatte, eine wesentliche Versteifung des Schwellenprofils und eine lagestabile Anordnung von Befestigungselementen oder Gleitstühlen für die Backenschiene bzw. Zungenschiene erzielt werden kann.The construction according to the invention is made in such a way that the ribbed plates have a substantially U-shaped outline and carry sliding chairs in the region of their legs extending in the threshold longitudinal direction. Such a substantially U-shaped outline having ribbed plate allows to arrange on the two legs of the ribbed slipper, so with a single component, namely the substantially U-shaped outline having ribbed plate, a substantial stiffening of the threshold profile and a storage-stable arrangement of fasteners or Sliding chairs for the stock rail or tongue rail can be achieved.
Zur Erzielung einer glatten Außenkontur und damit einer vollen schwellenvergleichbaren Geometrie ist mit Vorteil die Ausbildung so getroffen, dass die Trägerflansche zueinander gerichtet einwärts und im wesentlichen parallel zur Bodenplatte angeordnet sind. Auf diese Weise werden seitlich auskragende Trägerflansche vermieden, da die Trägerflansche einwärts gerichtet angeordnet sind.To achieve a smooth outer contour and thus a full threshold comparable geometry, the design is advantageously such that the support flanges are directed towards each other inwardly and arranged substantially parallel to the bottom plate. In this way laterally projecting support flanges are avoided, since the support flanges are arranged directed inwards.
Um bei schwingender Belastung eine vertikale Einfederung und keine andersartigen Verformungen sicherzustellen ist es auch denkbar, dass die Seitenwände gekrümmt oder geknickt mit zur Schwellenlängsachse parallelen Erzeugenden ausgebildet sind, deren vertikale Projektion zumindest teilweise auf der Bodenplatte liegt.In order to ensure a vertical deflection and no other deformations under oscillating load, it is also conceivable that the side walls are curved or bent with generatrices parallel to the threshold longitudinal axis whose vertical projection lies at least partially on the bottom plate.
Im Inneren einer derartigen trogartigen Schwelle können, wie bereits erwähnt, alle wesentlichen Elemente, beispielsweise eines Weichenantriebes aber auch andere für die Betriebssicherheit erforderlichen Einrichtungen, wie Kontrolleinrichtungen, Heißläuferortungseinrichtungen oder aber Anschlussgeräte für Sensoren untergebracht werden, wobei es vorteilhaft erscheint derartige Einrichtungen gegen Umwelteinflüsse weitestgehend zu schützen. Mit Vorteil ist die Ausbildung dabei so getroffen, dass die Seitenwände der Querschwelle Verriegelungsglieder für eine die Querschwelle in ihrer Längsrichtung zumindest teilweise übergreifende Abdeckung aufweisen, wobei derartige Verriegelungsglieder, beispielsweise nach Art eines Bajonettverschlusses von sich in Richtung der Schwellenlängsachse erstreckenden Vorsprüngen, Schlitzen oder Ausnehmungen gebildet sein können, in welcher der Deckel in Längsrichtung der Schwelle aufgeschoben werden kann.In the interior of such a trough-like threshold can, as already mentioned, all the essential elements, such as a points drive but also other required for operational safety devices, such as control devices, hot box locators or terminal devices be accommodated for sensors, where it seems advantageous to protect such facilities against environmental influences as far as possible. Advantageously, the training is made so that the side walls of the cross sleeper locking members for the cross sleeper in their longitudinal direction at least partially cross-cover, wherein such locking members, for example in the manner of a bayonet closure by itself in the direction of the threshold longitudinal axis extending projections, slots or recesses formed can be in which the lid can be pushed in the longitudinal direction of the threshold.
Die Verwendung einer einzigen Rippenplatte zur Erhöhung der Stabilität und zur Sicherstellung der entsprechenden Anschlußstellen für die Festlegung von Backenschienen oder anderen Bauteilen erlaubt es auch weitere Sonderfunktionen mit derartigen Rippenplatten zu verwirklichen, wobei mit Vorteil beispielsweise die Ausbildung so getroffen ist, daß die Rippenplatten Ausnehmungen für die Befestigung eines Weichenschlosses aufweisen. Ein derartiges Weichenschloß, welches eine mechanische Verriegelung der Weiche bietet, wenn ein Defekt im Antrieb oder ein Bruch eines kritischen Teiles beobachtet wird, erlaubt den Notbetrieb bis zur in der Folge vorgenommenen Reparatur.The use of a single ribbed plate to increase the stability and to ensure the appropriate connection points for the determination of stock rails or other components also allows other special functions with such ribbed plates to realize, with advantage, for example, the training is made so that the ribbed plates recesses for Attachment of a switch lock have. Such a switch lock, which provides a mechanical interlocking of the switch, if a defect in the drive or a fraction of a critical part is observed, allows the emergency operation until the subsequent repair.
Um sicherzustellen, daß keine über die seitliche Außenkontur der Querschwelle vorragenden Teile in der Folge hinderlich sind und beispielsweise bei Stopfvorgängen beschädigt werden können, ist die Ausbildung mit Vorteil so getroffen, daß die Breite der Rippenplatten quer zur Schwellenlängsrichtung der Breite der Schwelle entspricht.To ensure that no over the lateral outer contour of the cross member projecting parts are a hindrance in the sequence and can be damaged, for example, in stuffing operations, the training is advantageously made so that the width of the rib plates transverse to the threshold longitudinal direction corresponds to the width of the threshold.
Mit Vorteil werden hydraulische Weichenstellantriebe und Verschlußvorrichtungen in dem innerhalb der Querschwelle ausgebildeten Hohlraum untergebracht, wobei insbesondere im Fall von hydraulischen Weichenstellantrieben eine entsprechende Querbeweglichkeit derartiger Antriebe in Schienenlängsrichtung sicher vermieden werden soll. Mit Vorteil ist daher die Ausbildung so getroffen, daß die Querschwelle in ihrem mittleren Bereich vertikale Befestigungslaschen für die Befestigung einer Verschlußvorrichtung und/oder eines hydraulischen Weichenstellantriebes aufweist.Hydraulic Weichenstellantriebe and closure devices are advantageously housed in the cavity formed within the transverse threshold, in particular in the case of hydraulic Weichenstellantrieben a corresponding transverse mobility of such drives in the rail longitudinal direction should be avoided. Advantageously, therefore, the training is such that the cross sleeper has vertical attachment tabs for the attachment of a closure device and / or a hydraulic Weichenstellantriebes in its central region.
Um eine sichere und einfache Festlegung von Backenschienen zu ermöglichen, welche Längsausdehnungen der Schienen unter Temperatureinflüssen folgen kann, ist mit Vorteil die Ausbildung so getroffen, daß die Gleitstühle an ihrer dem die Trägerflansche übergreifenden Teil der U-förmigen Rippenplatte zugewandten Seite Ausnehmungen für das Übergreifen eines Schienenfusses einer Backenschiene aufweisen.In order to allow a safe and easy fixing of jaw rails, which longitudinal extensions of the rails can follow under the influence of temperature, the training is advantageously made such that the sliding chairs on their the carrier flanges have cross-section of the U-shaped rib plate facing side recesses for the overlapping of a rail foot of a stock rail.
Eine besonders stabile Ausführung der Querschwelle, welche auch die Aufnahme schwingender Belastungen gewährleistet, wird dadurch erreicht, daß die Bodenplatte in Richtung zur offenen Seite des trogförmigen Profiles gekrümmt oder geknickt mit zur Schwellenlängsachse parallelen Erzeugenden ausgebildet ist.A particularly stable design of the cross sleeper, which also ensures the inclusion of oscillating loads, is achieved in that the bottom plate is curved or bent in the direction of the open side of the trough-shaped profile formed with parallel to the emerging longitudinal axis generatrix.
Um den Widerstand gegen Seitenverschiebungen zu erhöhen, kann die Ausbildung in vorteilhafter Weise so getroffen sein, daß die Bodenplatte mit einer die Reibung erhöhenden Schicht versehen ist.In order to increase the resistance to side shifts, the training may be advantageously made so that the bottom plate is provided with a friction-increasing layer.
