Description
Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig bestehend aus einer Tragkonstruktion, einem Stufenband mit motorisierten Stufen und freilaufenden Stufen bzw. Palettenband mit motorisierten Paletten und freilaufenden Paletten für den Transport von Personen und/oder Gegenständen und einer mittels eines Balustradensockels gehaltenen Balustrade mit Handlauf.The invention relates to an escalator or a moving walkway consisting of a supporting structure, a stepped belt with motorized steps and free-running stages or pallet conveyor with motorized pallets and free-moving pallets for the transport of people and / or objects and a balustrade held by means of a balustrade balustrade with handrail.
Aus der
Nachteilig bei dieser Antriebseinrichtung ist, dass die zwei je Stufe vorgesehenen Zahnräder beim Kämmen mit den Zahnstangen übermässig Geräusche verursachen. Die Stufe muss präzise geführt werden, damit die Zahnräder sauber mit den Zahnstangen im Eingriff stehen. Ausserdem ist die Antriebsmechanik mit Pulleys, Riemen oder Ketten, Achsen, Zahnrädern und Zahnstangen mechanisch aufwendig, kostspielig und wartungsintensiv. Gleichlaufprobleme entstehen wegen den angetriebenen Stufenrollen und den angetriebenen Kettenrollen.A disadvantage of this drive device is that the two gears provided for each stage cause excessive noise when combing with the racks. The step must be precisely guided so that the gears mesh cleanly with the racks. In addition, the drive mechanism with pulleys, belts or chains, axles, gears and racks is mechanically complex, costly and maintenance-intensive. Synchronism problems arise because of the driven step rollers and the driven chain rollers.
Aus der
Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Antriebseinrichtung zu schaffen, die auf einfache Art und Weise eine Stufe bzw. eine Palette eines Stufenbandes bzw. eines Palettenbandes antreibt.The invention aims to remedy this situation. The invention, as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and to provide a drive device which drives in a simple manner a step or a pallet of a step belt or a pallet strip.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die für den Vortrieb der Stufe bzw. der Palette notwendige Kraftübertragung an einem Punkt erfolgt, was gewährleistet, dass die Stufe bzw. die Palette vom Antrieb her nicht verkanten kann. Ausserdem sind für die Motorisierung der Stufen bzw. Paletten nur wenige zusätzliche Fahrtreppen- bzw. Fahrsteigteile notwendig. Die mittig angeordnete Fahrbahn zur Fortbewegung der motorisierten Stufe dient auch als Bremsschiene für die je motorisierte Stufe vorgesehene Bremse.The advantages achieved by the invention are essentially to be seen in the fact that the power transmission necessary for the propulsion of the stage or the pallet takes place at one point, which ensures that the step or the pallet can not tilt from the drive. In addition, only a few additional escalator or moving walk parts are necessary for the motorization of the stages or pallets. The centrally arranged roadway for locomotion of the motorized stage also serves as a brake rail for the ever motorized stage provided brake.
