Description

Die gegenständliche Erfindung betrifft eine Seilbahnanlage mit in der Talstation und in der Bergstation befindlichen Trägern mit an diesen verdrehbar gelagerten Seilumlenkscheiben, deren mindestens eine angetrieben ist, und mit einem um die Seilumlenkscheiben gelegten und über Führungsrollen bzw. Ablenkrollen geleiteten Förderseil für die Bewegung von Sesseln oder Kabinen.The subject invention relates to a cable car system with supports located in the valley station and in the mountain station with rotatably mounted rope deflection disks, at least one of which is driven, and with a conveyor rope for the movement of armchairs or guided around the rope deflection disks and guided via guide rollers or deflection rollers Cabins.

Bei bekannten Seilbahnanlagen ist entweder in der Talstation oder in der Bergstation ein Antriebsmotor vorgesehen, durch welchen die Seilumlenkscheibe über ein Getriebe und eine Kupplung antreibbar ist. Ein Getriebe ist deshalb erforderlich, um die Umdrehungsgeschwindigkeit der Seilumlenkscheibe, mit welcher das Trag- und Förderseil bewegt wird, zu reduzieren. Ein derartiger Antrieb ist jedoch deshalb nachteilig, da zusätzlich zum Elektromotor das Getriebe und eine Kupplung vorgesehen sein müssen, welche störungsanfällig sind, da weiters durch das Getriebe Geräuschentwicklungen bedingt werden und da schließlich diese Bauteile Abnützungen unterliegen, weswegen sie gleichfalls störungsanfällig sind.In known cable car systems, a drive motor is provided either in the valley station or in the mountain station, by means of which the cable deflection pulley can be driven via a gear and a clutch. A gearbox is therefore required to reduce the speed of rotation of the rope deflection pulley with which the carrying and conveying rope is moved. However, such a drive is disadvantageous because, in addition to the electric motor, the gearbox and a clutch must be provided, which are susceptible to malfunction, because noise is also caused by the gearbox and because these components are subject to wear and tear, which is why they are also prone to failure.

Aus der FR-A-2 514 094 ist eine Seilbahnanlage bekannt, bei welcher die Seilscheibe mit den Rotoren zweier hydraulischer Motoren fest verbunden ist. Dieser bekannten Anlage liegt ebenso wie der erfindungsgemäßen Anlage die Aufgabe zugrunde, eine Steuerung der Rotationsgeschwindigkeit der Seilumlenkscheibe zu ermöglichen, ohne daß es zwischen dem Antriebsmotor und der Seilumlenkscheibe eines Getriebes bedarf. Bei der bekannten Seilbahnanlage wird diese Aufgabe mittels zweier hydraulischer Motoren gelöst.From FR-A-2 514 094 a cable car system is known in which the cable pulley is firmly connected to the rotors of two hydraulic motors. This known system, like the system according to the invention, is based on the object to enable control of the speed of rotation of the cable deflection disc without the need for a gearbox between the drive motor and the cable deflection disc. In the known cable car system, this problem is solved by means of two hydraulic motors.

Bei der anmeldungsgemäßen Seilbahnanlage wird demgegenüber diese Aufgabe erfindungsgemäß dadurch gelöst, daß am Träger für die angetriebene Seilumlenkscheibe eine scheibenförmige Platte befestigt ist, an deren äußerem Umfang ringförmig eine Vielzahl von an eine Steuerschaltung angeschlossenen Elektromagneten angeordnet ist, durch deren aufeinanderfolgende Erregung ein ringsumlaufendes Magnetfeld erzeugbar ist, und daß die Seilumlenkscheibe an ihrem äußeren Umfangsrand mit einem nach oben abragenden, ringförmigen Flansch ausgebildet ist, an dessen Innenseite mindestens eine Gruppe von Permanentmagneten angeordnet ist, welche den Elektromagneten zugeordnet sind und welche durch das ringsumlaufende Magnetfeld angezogen bzw. abgestoßen werden, wodurch die Seilumlenkscheibe verdreht wird.In the case of the cable car system according to the invention, however, this object is achieved according to the invention in that a disk-shaped plate is attached to the carrier for the driven cable deflection disk, on the outer circumference of which a plurality of electromagnets connected to a control circuit is arranged in a ring, through the successive excitation of which a circumferential magnetic field can be generated , and that the cable deflection disk is formed on its outer peripheral edge with an upwardly projecting, annular flange, on the inside of which at least one group of permanent magnets is arranged, which are assigned to the electromagnets and which are attracted or repelled by the circumferential magnetic field, as a result of which Rope deflection pulley is rotated.

Vorzugsweise sind hierbei der Ring von Elektromagneten und die Seilumlenkscheibe durch ein Gehäuse nach oben hin abgeschlossen.The ring of electromagnets and the cable deflection disk are preferably closed off at the top by a housing.

Dieses Prinzip des Antriebes, welches an sich bekannt ist, ist in der Fachliteratur als Magnetmotor bezeichnet. Die Verwendung dieses Prinzips für den Antrieb von Seilumlenkscheiben ist bislang nicht bekannt. Die besonderen erfinderischen Effekte bestehen dabei darin, daß der Rotor des Antriebsmotors gleichzeitig die Seilumlenkscheibe bildet, weswegen kein Erfordernis dafür besteht, zwischen dem Rotor des Antriebsmotors und der Seilumlenkscheibe eine Kupplung und ein Getriebe vorzusehen. Hierdurch wird einerseits die Störungsanfälligkeit der Anlage vermindert und wird andererseits auch der Wartungsaufwand herabgesetzt. Die Steuerung der Rotationsgeschwindigkeit erfolgt dabei dadurch, daß die Elektromagneten mittels der Steuerschaltung aufeinanderfolgend erregt werden.This principle of the drive, which is known per se, is referred to in the technical literature as a magnetic motor. The use of this principle for driving rope deflection pulleys is not yet known. The particular inventive effects consist in the fact that the rotor of the drive motor simultaneously forms the cable deflection disc, which is why there is no need to provide a clutch and a transmission between the rotor of the drive motor and the cable deflection disc. On the one hand, this reduces the susceptibility to faults of the system and, on the other hand, the maintenance effort is reduced. The rotation speed is controlled thereby that the electromagnets are excited successively by means of the control circuit.

Der Gegenstand der Erfindung ist nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Fig. 1
eine Seilumlenkscheibe mit einem erfindungsgemäßen Antrieb, in axonometrischer Darstellung, und
Fig. 2
die Seilumlenkscheibe gemäß Fig. 1, in axialem Schnitt.
The object of the invention is explained below with reference to an embodiment shown in the drawing. Show it:
Fig. 1
a rope deflection plate with a drive according to the invention, in axonometric representation, and
Fig. 2
1, in axial section.

In Fig. 1 ist eine Säule 1 als Träger bzw. als Lager für eine Seilumlenkscheibe 2 dargestellt. Die Seilumlenkscheibe 2 ist an ihrer Unterseite mit einer Führungsrille 21 für das Trag- und Förderseil 3 ausgebildet. Am Träger 1 sind weiters mittels eines Gestells 11 Führungs- bzw. Leitrollen 12 gelagert. An das Trag- und Förderseil 3 sind Sessel 5 angekuppelt. Oberhalb der Seilumlenkscheibe 2 ist eine Abdeckung 16 vorgesehen.In Fig. 1, a column 1 is shown as a carrier or as a bearing for a cable deflection pulley 2. The cable deflection pulley 2 is formed on its underside with a guide groove 21 for the carrying and conveying cable 3. Guide or guide rollers 12 are also mounted on the carrier 1 by means of a frame 11. Armchairs 5 are coupled to the carrying and conveying rope 3. A cover 16 is provided above the cable deflection pulley 2.

Wie dies aus Fig. 2 ersichtlich ist, ist die Seilumlenkscheibe 2 an ihrem äußeren Umfangsrand mit einem nach oben abragenden Flansch 22 ausgebildet, an dessen Innenseite mindestens eine Gruppe von nebeneinander angeordneten Elektromagneten 24 oder Permanentmagneten 24' getragen ist. Am Träger 1 ist weiters eine scheibenförmige Platte 13 befestigt, an deren äußerem Umfang eine Vielzahl von ringförmig angeordneten Elektromagneten 14 angeordnet ist. Die Elektromagneten 14 sind über Steuerleitungen 15 mit einer Speise- und Steuerschaltung verbunden. Die Seilumlenkscheibe 2 ist mittels eines Lagers 25 gegenüber dem Träger 1 verdrehbar.As can be seen from FIG. 2, the cable deflection disk 2 is formed on its outer peripheral edge with an upwardly projecting flange 22, on the inside of which at least one group of electromagnets 24 or permanent magnets 24 'arranged next to one another is carried. Furthermore, a disk-shaped plate 13 is fastened to the carrier 1, on the outer circumference of which a multiplicity of ring-shaped electromagnets 14 are arranged. The electromagnets 14 are connected to a supply and control circuit via control lines 15. The cable deflection disk 2 can be rotated relative to the carrier 1 by means of a bearing 25.

Durch diese Anordnung ist ein Antriebsmotor geschaffen, dessen Stator durch die Scheibe 13 mit dem Elektromagneten 14 und dessen Rotor durch die Seilumlenkscheibe 2 mit den Magneten 24 und 24' gebildet ist. Die Verdrehung der Seilumlenkscheibe 2 wird dadurch bewirkt, daß durch aufeinanderfolgende Erregung der ringförmig nebeneinander angeordneten Elektromagneten 14 ein ringsumlaufendes Magnetfeld erzeugt wird, durch welches die Magneten 24 und 24' angezogen bzw. abgestoßen werden, wodurch die als Rotor dienende Seilumlenkscheibe 2 verdreht wird. Hierdurch dient die Seilumlenkscheibe 2 als Antrieb für das Trag- und Förderseil 3.This arrangement creates a drive motor, the stator of which is formed by the disk 13 with the electromagnet 14 and the rotor of which is formed by the cable deflection disk 2 with the magnets 24 and 24 '. The twisting of the rope deflection disk 2 is brought about by successive excitation a circumferential magnetic field is generated by the electromagnets 14 arranged next to one another in a ring, by means of which the magnets 24 and 24 'are attracted or repelled, as a result of which the rope deflection disk 2 serving as a rotor is rotated. As a result, the cable deflection pulley 2 serves as a drive for the carrying and conveying cable 3.
