Description

Die vorliegende Erfindung bezieht sich auf eine Antriebsanlage mit Einrichtung zum geregelten und/oder modulierten Absteuern und Stillsetzen einer Seilbahn gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a drive system with a device for controlled and / or modulated shutdown and shutdown of a cable car according to the preamble of claim 1.

Bei Anlagen dieser Art wird häufig eine Lösung gesucht, bei der es nicht erforderlich sein soll, ein Untersetzungsgetriebe, Antrieb und Antriebscheibe zu verwenden, und daher keine Kraftübertragung von einem Antrieb auf ein Getriebe vorhanden sein soll. Überdies wird ständig versucht, die Anzahl von bewegten Teilen und Verschleißteilen verringern. Die Wartung soll möglichst wenig aufwendig sein und die Lärmentwicklung begrenzt sein. Der Wirkungsgrad sollte mit einem hohen cosϕ groß und die Netzverschmutzung möglich klein sein.In systems of this type is often sought a solution in which it should not be necessary to use a reduction gear, drive and drive pulley, and therefore no power transmission from a drive to a transmission should be present. Moreover, it is constantly trying to reduce the number of moving parts and wearing parts. The maintenance should be as little as possible and the noise be limited. The efficiency should be high with a high cosφ and the network pollution possible to be small.

Um diese Ergebnisse zu erhalten, wurden in der letzten Zeit an Seilbahnanlagen Direktantriebe ausgeführt, d.h. Anlagen bei denen keine Untersetzungsgetriebe erforderlich werden.In order to obtain these results, direct drives have recently been carried out on ropeway installations, i. Systems where no reduction gear is required.

Derartige Systeme sind z.B aus den Druckschriften JP 04 066 362, GB 2 111 326 und US 5 856 712 bekannt.Such systems are known for example from the publications JP 04 066 362, GB 2 111 326 and US 5,856,712.

Der Nachteil einer solchen Anlage besteht darin, dass rotierende Massen fehlen, die daher ein ganz verschiedenes Bremsverhalten der Anlage gegenüber den herkömmlichen Anlagen ausüben. Bei steilen Seilbahnen und Anlagen mit großer Stundenleistung kann es durch die fehlenden rotierenden Massen zu einer sehr hohen Eigenverzögerung kommen, sodass die von der Norm vorgegebenen maximalen Bremsverzögerungen mit Last bergwärts nicht mehr eingehalten werden können.The disadvantage of such a system is that rotating masses are missing, which therefore a very different braking behavior of the system exercise over conventional systems. With steep ropeways and systems with high hourly output, the lack of rotating masses can lead to a very high self-delay, so that the maximum braking deceleration set by the standard with load uphill can no longer be met.

Es bestehen nun mehrere Möglichkeiten dieses Problem zu lösen:

  • Es kann die Masse der Antriebsscheibe so stark vergrößert werden, dass die Eigenverzögerung wieder die geforderten Werte erreicht.
  • Man kann ein ein- oder mehrstufiges Zwischengetriebe zwischen Motor und Antriebscheibe schalten, wobei man jedoch keinen echten Direktantrieb mehr hätte.
There are several ways to solve this problem:
  • The mass of the drive disk can be increased so much that the self-retardation again reaches the required values.
  • You can switch a single or multi-stage intermediate gear between the engine and drive pulley, but you would have no real direct drive more.

Die Aufgabe der vorliegenden Erfindung ist daher die, die durch die Direktantriebe gegebenen Probleme zu lösen und die Bremsung, beispielsweise bei Ausfall der Energiezufuhr derart zu gestalten, dass eine Bremsstrecke mit einer durch die Norm vorgeschriebene Höchstgeschwindigkeit erhalten wird, ohne dass zusätzliche Trägheitsmassen oder Schwungmassen vorgesehen werden müssten.The object of the present invention is therefore to solve the problems given by the direct drives and to make the braking, for example in case of failure of the power supply such that a braking distance is obtained with a prescribed by the standard speed without additional inertial masses or masses provided would have to be.

Diese Aufgabe wird erfindungsgemäß in einer Antriebsanlage mit geregeltem Absteuern und Stillsetzen einer Seilbahn mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved in a drive system with controlled Absteuern and Stopping a cable car with the features of the characterizing part of claim 1 solved.

So kann nach Anspruch 1 die Verzögerung der Anlage aktiv beeinflusst werden, indem der Anlage selbst Energie zugeführt wird, damit sie geschwindigkeitsabhängig abgesteuert und der Anhalteweg/Stillsetzweg durch den Motor vorgegeben wird. Beim Anhalten bzw. Stillsetzen der Anlage wird von der Steuerung bzw. Regelung unterschieden, ob die Anlage bergwärts (motorisch) oder talwärts (generatorisch) fördert.Thus, according to claim 1, the delay of the system can be actively influenced by the system itself energy is supplied so that it is speed-dependent controlled and the stopping distance / shutdown path is set by the engine. When stopping or stopping the system, a distinction is made between the controller and the controller as to whether the system conveys uphill (motorized) or downhill (regenerative).

Bei motorischem Betrieb wird die Anlage nach folgendem Schema stillgesetzt:

  • Stillsetzen der Anlage mit dem Nothaltantriebsmotor, der ohne Probleme in Betrieb ist, solange das Netz Energie liefert,
  • bei Ausfall der Energiezufuhr (Netz, Generator) wird die für die Absteuerung bzw. Abschaltung der Anlage notwendige Energie aus einer unabhängigen Energiequelle entnommen und der Motor setzt die Anlage nach einer durch Speisung seitens der unabhängigen Energiequelle vorgegebenen Rampe still,
  • in einer unter Sicherheitsüberlegungen bevorzugten Ausführungsform können diese Energiequelle und die entsprechende Regelung redundant oder auch derart ausgeführt werden, dass beispielsweise bei Nichtfunktionieren einer der Energiequellen die andere Energiequelle zum Wirken kommt,
  • in Anwesenheit einer Mindestgeschwindigkeit fällt dann die normale Betriebsbremse ein.
In motorized operation, the system is shut down according to the following scheme:
  • Shutting down the system with the emergency stop drive motor, which operates without any problems as long as the grid supplies energy,
  • in case of failure of the power supply (grid, generator), the energy required for the shutdown or shutdown of the system is taken from an independent source of energy and the engine stops the system after a predetermined by supply from the independent energy source ramp,
  • in a preferred embodiment, this energy source and the corresponding regulation be performed redundantly or in such a way that, for example, when one of the energy sources does not work the other energy source comes to work,
  • in the presence of a minimum speed then falls the normal service brake.
