Im Stand der Technik sind verschiedene Anordnungen für Personenaufzüge bekannt.Various arrangements for passenger elevators are known in the art.
DE 295 20 175 U1 beschreibt eine Liftvorrichtung mit einem Schienensystem und einem entlang des Schienensystems bewegbaren Lift, z.B. einem Sessellift für eine behinderte Person. Der Lift kann sich unter einem Winkel, wenigstens entlang eines Teils seines Weges, nach oben bewegen, wobei das Schienensystem zwei Führungen aufweist, wovon eine im wesentlichen über der anderen vorgesehen ist, wodurch der Abstand zwischen den Führungen von dem Neigungswinkel der Führungen abhängt und Halteelemente die zwei Führungen verbinden. Die zwei Führungen sind jeweils lösbar mit den Halteelementen verbunden.
Diese Anordnung ist für den Einsatz im Freien nicht geeignet.DE 295 20 175 U1 describes a lifting device with a rail system and a lift which can be moved along the rail system, for example a chairlift for a disabled person. The lift may move upwards at an angle, at least along part of its path, the rail system having two guides, one of which is substantially above the other, whereby the distance between the guides depends on the angle of inclination of the guides and holding elements connect the two guides. The two guides are each releasably connected to the holding elements.
This arrangement is not suitable for outdoor use.

Gemäß Figur 1 wird die Gondel 1 des Liftes in einer Laufschiene 10 bewegt. Die Laufschiene 10 besteht im dargestellten Beispiel aus einem gekanteten C-Profil aus 8 mm dickem Stahlblech St52-2. Im Abstand von ca. 2 m sind Stützen 9 in einem betonierten Fundament angebracht. Die Laufschiene 10 ist an den Stützen 9 in einer Höhe von ca. 1 m über dem Boden befestigt. Die Laufschiene 10 nimmt die Gewichts- und Beschleunigungskräfte der Gondel 1 auf. Unterhalb der Laufschiene 10 befindet sich eine geschlossene Stromführungsschiene, welche die Stromversorgung der Gondel 1 und des Antriebs sicherstellt. Dabei ist gewährleistet, dass die Stromführungsschienen den nach DIN erforderlichen Berührungsschutz aufweisen.According to FIG. 1 , the nacelle 1 of the lift is moved in a running
Die Gondel 1 verfügt über einen verglasten Profilrahmen aus Aluminium. Sie ist im oberen Drittel an einer Aufhängung 3 mit der Antriebseinheit 2 verbunden ist. Diese Aufhängung gewährleistet unabhängig von der Steigung die senkrechte Stellung der Gondel 1, wobei mit Stoßdämpfern ein Schwingen der Gondel 1 verhindert wird. Die Gondel 1 ist für vier Personen vorgesehen und hat eine Grundfläche von 0,8 m2, wobei eine Schiebetür die Begehbarkeit ermöglicht. Sie erfüllt die Aufzugsrichtlinie nach DIN EN81-1.The gondola 1 has a glazed aluminum profile frame. It is connected in the upper third to a
Die aus Figur 2 ersichtliche Antriebseinheit 2 ist in kompakter Bauweise ausgeführt und beinhaltet alle für die mechanischen Stütz- und Fangfunktionen erforderlichen Bauteile. Sie besteht aus einem Halterrahmen, an dem vier Laufräder 7 zur Aufnahme der axialen Kräfte der Gondel 1 befestigt sind. Diese sind mit Hilfe von Exzendern einstellbar. Die vertikalen Kräfte werden über seitliche Laufrollen 8 auf die Seitenflanken des C-Profils der Laufschiene 10 übertragen. In die Laufschiene 10 ist eine Winkelschiene 6 aus Edelstahl X8 Cr Ti 17 eingeschraubt. Diese ermöglicht die formschlüssige Kraftübertragung von der Gondel 1 zur Laufschiene 10. Die Winkelschiene 6 ist über ihre gesamte Länge mit Durchbrüchen versehen, die in konstantem Abstand angebracht sind und eine formschlüssige Verbindung mit dem Antriebsrad 5 herstellen und somit die Bewegung der Gondel 1 ermöglichen. In der Winkelschiene 6 befindet sich ein Führungselement, dass vier Laufräder 7 und seitliche Laufrollen 8 enthält. Dabei liegen jeweils zwei Laufräder 7 an gegenüberliegenden Innenflächen 10.1 des C-Profils an. Die Laufrollen 8 sind paarweise angebracht, wobei jeweils zwei Rollenpaare an der hinteren Fläche 10.2 der Laufschiene (10) sowie an den dieser Fläche gegenüberliegenden abgekanteten Gegenflächen 10.3 anliegen.The apparent from Figure 2
Figur 3 erläutert die Antriebseinheit. Als Antriebsmotor 4 ist ein Kegelradgetriebemotor mit Doppelbremse vorgesehen, der über einen Frequenzumrichter gesteuert wird. Um eine hohe Sicherheit zu gewährleisten ist das Antriebsrad 5 direkt mit der Motorwelle verbunden.
Im Normalbetrieb werden das Anfahren und Bremsen der Gondel 1 mit dem Frequenzumrichter gesteuert. Für die Positionssteuerung ist hierzu eine handelsübliche Liftsteuerung vorgesehen.
Im Notfall oder bei Stromausfall wirken die beiden voneinander unabhängigen Motorbremsen. Die Antriebseinheit enthält eine zusätzliche Fangeinrichtung, die bei einem Versagen des Antriebs mechanisch eingreift, wenn eine vorgegebene Geschwindigkeit überschritten wird. FIG. 3 explains the drive unit. As a
In normal operation, the starting and braking of the nacelle 1 are controlled by the frequency converter. For the position control for this purpose, a commercially available lift control is provided.
In an emergency or power failure, the two independent engine brakes act. The drive unit includes an additional catching device, which mechanically engages in case of failure of the drive when a predetermined speed is exceeded.
In Figur 4 zeigt die Anordnung des Antriebsrades 5 im Eingriff mit der Winkelschiene 6 sowie die Anordnung der vier Laufräder 7.In Figure 4 shows the arrangement of the
Eine weitere Ausführungsmöglichkeit ist in Figur 5 dargestellt. Hierbei sind auf einem Drahtseil 11 Mitnehmer 12 befestigt. Das Drahtseil 11 mit den Mitnehmern 12 ist in definierten Abständen mit der Laufschiene 10 fest verbunden. Bei der Drehbewegung des Antriebsrades 5 greift dessen Verzahnung über die Mitnehmer 12 und bildet eine formschlüssige Verbindung. Um die Anlage des Drahtseiles 11 am Antriebsrad zu sichern, befindet sich unter dem Antriebsrad 5 ein Gegenrad 13, sodass die formschlüssige Verbindung zwischen den Mitnehmern 12 und dem Antriebsrad 5 stets gewährleistet ist. Bei dieser Ausführung ist vorteilhaft, dass bei Richtungs- und Steigungsänderungen auftretende Fluchtungsfehler vernachlässigt werden können, da sich das Drahtseil 11 den Änderungen anpassen kann.Another embodiment is shown in FIG .
