Description

Dämpfungsvorrichtung für Zugseile von SeilbahnenDamping device for pull ropes of cable cars
Die vorliegende Erfindung bezieht sich auf eine Dämpfungsvorrichtung für Zugseile von Seilbahnen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a damping device for pull ropes of cable cars according to the preamble of claim 1.
Seilbahnen dieser Art umfassen ein zwischen einer Tal- und einer Bergstation gespanntes Tragseil und ein Zugseil, das sich in den entsprechenden Stationen durch jeweils eine Scheibe umgelenkt kontinuierlich bewegt wird, von denen eine eine Antreibscheibe ist. Auf dem Tragseil laufen die Fahrwerke der Kabinen, die an den Fahrwerken selbst über eine Aufhängung angehängt sind, die mit dem Zugseil über eine Klemme kuppelbar sind. Die Klemme selbst weist in diesem Fall einen Klemmrücken auf einer der Backen auf, der vom Zugseil nach unten ragt.Cable cars of this type comprise a suspension cable stretched between a valley and a mountain station and a pulling cable which is continuously moved in the respective stations by a pulley, one of which is a drive pulley. The carriages of the cabins run on the suspension cable, which are attached to the carriages themselves via a suspension, which can be coupled to the traction cable via a clamp. In this case, the clamp itself has a clamping back on one of the jaws, which protrudes downward from the pull rope.
Im Fall wo zwischen der Tal- und Bergstation Stützen vorhanden sind, die das Tragseil in seinem Verlauf über einen Träger und das Zugseil über eine Rollenbatterie abstützen, besteht das Problem, dass die Klemme beim Durchlauf des Fahrwerkes das Zugseil anheben muss, um nicht mit der Rollenbatterie in Berührung zu kommen. Gleich nach dem Durchlaufen des Fahrzeugs legt sich das Zugseil von Neuem auf die Rollenbatterie der Stütze und der Aufprall erzeugt eine Welle bzw. eine Schlagbewegung im Zugseil, die sich längs der Linie ausbreitet, wobei sie zu- r:ückgeworfen wird, und die Amplitude bei der Annäherung des Fahrzeuges vor allem wenn sich die Wellenberge der fortgepflanzten und jener zurückgeworfenen Wellen überlagern. Es ist leicht vorstellbar, dass diese Wellen Fiat- terbewegungen erzeugen und, außer für die Passagiere unangenehm zu sein, eine unlässige Bewegung des Zugseils hervorrufen könnten.In the case where there are supports between the valley and mountain stations, which support the suspension cable in its course by means of a beam and the cable by means of a roller battery, there is the problem that the clamp has to lift the cable when the running gear runs through, in order not to use the Roller battery to come into contact. Immediately after passing through the vehicle, the traction cable lays down again on the roller battery of the support and the impact creates a wave or striking movement in the traction cable, which spreads along the line, being thrown back and the amplitude the approach of the vehicle, especially when the wave crests of the propagated and the reflected waves overlap. It is easy to imagine that these waves Fiat movements and, apart from being uncomfortable for the passengers, could cause the traction rope to move.
Die Aufgabe der vorliegenden Erfindung ist daher das Problem der Wellenerzeugung zu unterdrücken oder zumindest zu reduzieren, indem die Schlag- und Flatterbewegungen in einem Höchstmaß vermieden werden, indem eine Däm- mungs- und Stoßauffangvorrichtung geschaffen wird, die die Ursache der Wellenbildung in einem Höchstmaß eingrenzt .The object of the present invention is therefore to suppress or at least reduce the problem of wave generation by avoiding the striking and fluttering movements to a maximum extent, by creating an insulation and shock absorbing device which limits the cause of the wave formation to a maximum extent ,
Diese Aufgabe wird erfindungsgemäß im ken zeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in the ken drawing part of claim 1.
Wird am Eingang der Rollenbatterie ein Hebel angelenkt, der an seinem anderen Ende eine am Zugseil angreifende Rolle trägt und wird der Hebel selbst über Federmittel oder Gewichte in Richtung des Zugseils belastet, so legt sich der Klemmrücken oder auch die Auflauf zunge der Klemme, soweit vorhanden, weicher auf diese abgedämpfte Rolle der Rollenbatterie. Die Belastung dieses Hebels wird derart gewählt, dass der Durchlauf auf dieser Rolle auf dem Klemmrücken sanft gestaltet wird. In einer Weiterbildung wird der Hebel durch eine Feder belastet und durch einen Stoßdämpfer gedämpft.If a lever is articulated at the entrance of the roller battery, which carries a roller acting on the pulling rope at its other end and if the lever itself is loaded in the direction of the pulling rope via spring means or weights, the clamping back or the overlap tongue of the clamp, if present, will lay down , softer on this dampened role of the roll battery. The load on this lever is selected in such a way that the passage on this roller on the clamping back is designed gently. In a further development, the lever is loaded by a spring and damped by a shock absorber.
Bevorzugter Weise ist der Stoßdämpfer einstellbar und pneumatischer oder hydraulischer Art.The shock absorber is preferably adjustable and of a pneumatic or hydraulic type.
In einem weiteren Ausführungsbeispiel ist dem einer Rolle angelenkte Hebel, bevorzugter Weise vor dex ersten Rolle der Rollenbatterie ein zweiarmiger Hebel zugeordnet, von dem einer der Arme im Bereich seines ersten freien Endes an einem Stützaufbau angelenkt und durch eine Druckfeder gegenüber der Rollenbatterie abgestützt, während der andere Arm an seinem freien Ende eine Führung trägt, die auf dem Tragseil läuft, wobei im. Hebelknie des zweiarmigen Hebels ein Widerstandsmittel vorgesehen ist, das auf dem an der ersten Rolle angelenkten Hebel läuft, wobei der Hebel mit einem optimalen Abstand niedergedrückt wird, um der Klemme zu erlauben, oberhalb dieser Rolle ohne Überschneidung durchzulaufen.In a further exemplary embodiment, the lever articulated to a roller, preferably a two-armed lever is assigned in front of the first roller of the roller battery, by one of the arms articulated in the region of its first free end to a support structure and supported by a compression spring against the roller battery, while the other arm carries a guide at its free end that runs on the supporting cable, wherein in. A resistance means is provided on the lever knee of the two-armed lever which runs on the lever articulated on the first roller, the lever being pressed down at an optimal distance to allow the clamp to pass above this roller without overlap.
In einer Variante ist die Führung des zweiten Arms durch eine Kehlröllchen gebildet.In a variant, the guide of the second arm is formed by a throat roll.
Bevorzugter Weise ist das Widers tandsmittel ein Zapfen oder ein Rädchen.The opposing means is preferably a pin or a cog.
