Abstract

The lift comprises a drive mechanism (4) mounted at the top end of the lift shaft (1), having a pulley (4.1) driving the cage (2) and counterweight (3) by ropes. The cage and weight work in guides (6) in the shaft. The mechanism can be contained in a frame on the end of a swing arm whose other end works in a supporting yoke at the top end of the shaft or guide. A drive mechanism can be provided for the arm, with electric motor or hand crank, while a locking mechanism can fix the arm in the yoke in the working position, the drive mechanism being then horizontal with the pulley at its underside.

Description

Die Erfindung betrifft eine Aufzugsanlage mit am oberen Ende eines Aufzugsschachtes angeordneter Antriebseinheit mit Treibscheibe für den Antrieb mittels Seilen einer im Aufzugsschacht an Führungselementen geführter Aufzugskabine mit Gegengewicht.The invention relates to an elevator system at the top Drive unit arranged at the end of an elevator shaft with traction sheave for the drive by means of ropes one in Elevator shaft on elevator car guided by guide elements with counterweight.

Aus dem Gebrauchsmuster DE-GM 88 07 219 ist eine Aufzugsanlage bekannt geworden mit einem vom Boden des unteren Stockwerk bis zur Decke des oberen Stockwerkes reichenden Rahmen als Führungselement einer Aufzugskabine. Der Rahmen weist unterhalb der Decke des oberen Stockwerkes eine aus Querbalken bestehende Bühne für Elektromotor, Aufzugswinde und Schaltanlage auf. Die Aufzugskabine gleitet auf Laufrollen an den Innenseiten von Winkeleisen des Rahmens. Die Aufzugsseile werden über zwei Umlenkrollen, die sich auf der Höhe der Bühne befinden einer Seiltrommel zugeführt und gegenläufig auf- bzw. abgewickelt.From the utility model DE-GM 88 07 219 is one Elevator became known with a from the bottom of the lower floor to the ceiling of the upper floor reaching frame as a guide element of an elevator car. The frame points below the ceiling of the upper floor a cross-beam stage for the electric motor, Elevator winch and switchgear on. The elevator car slides on rollers on the inside of angle iron of the frame. The elevator ropes are over two Deflection rollers that are at the level of the stage fed to a rope drum and opened or closed in opposite directions handled.

Ein Nachteil der bekannten Einrichtung liegt darin, dass sich die Anordnung der Antriebseinheit und die Seilführung nicht für eine Aufzugsanlage mit einem Gegengewicht eignet. Weiter nachteilig ist, das die unterhalb der Decke angeordnete Antriebseinheit mit Motor und Aufzugswinde sowie Schaltanlage für Unterhaltsarbeiten nur mit Mühe erreichbar sind.A disadvantage of the known device is that the arrangement of the drive unit and the cable guide not suitable for an elevator system with a counterweight. Another disadvantage is that the below the ceiling arranged drive unit with motor and elevator winch and switchgear for maintenance work with difficulty are reachable.

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 Aufzugsanlage mit einer Antriebseinheit zu schaffen, die im Aufzugsschacht platzsparend angeordnet werden kann und leicht zugänglich ist.The invention seeks to remedy this. The invention, as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and to create an elevator system with a drive unit, which can be arranged in a space-saving manner in the elevator shaft and is easily accessible.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Aufzugsanlage keinen Maschinenraum benötigt, wodurch die üblicherweise notwendigen und kostspieligen Dachaufbauten oder Kellerräume für den Maschinenraum entfallen. Weiter vorteilhaft ist, dass minimale Schachtabmessungen insbesondere im Überfahrbereich möglich sind. Ein weiterer entscheidender Vorteil ist, dass die Aufzugsanlage unabhängig von der Bausubstanz und von der Tragkraft der Schachtdecke ist, weil die erfindungsgemässe Aufzugsanlage lediglich einen selbsttragenden Aufzugsschacht benötigt.The advantages achieved by the invention are in essential to see that the elevator system none Engine room needed, which is the usual necessary and expensive roof structures or Basement rooms for the machine room are eliminated. Continue It is advantageous that the minimum shaft dimensions are possible in particular in the drive-over area. Another decisive advantage is that the elevator system regardless of the building structure and the load capacity of the Manhole cover is because the elevator installation according to the invention only a self-supporting elevator shaft is required.

Zum Schwenken der Antriebseinheit 4 wird das Getriebe 19 beispielsweise mittels einer an einem Kurbelzapfen 22 ansetzbaren Kurbel angetrieben. Das Getriebe kann auch motorisch angetrieben werden. Die mittels Getriebe 19 angetriebene Schwenkachse 20 schwenkt den Schwenkarm 17 und somit das Gestell 18 mit der Antriebseinheit 4 in den Aufzugsschacht 1. In der mit unterbrochener Linie gezeigten Lage sind Montage-, Unterhalts- und Reparaturarbeiten leicht und gut zugänglich ausführbar. Eine Seilablenkung 23 ist mit der Schwenkachse 20 lose verbunden und verhindert, dass kein übermässiger Seilschrägzug auf der Treibscheibe 4.1 entstehen kann.2 and 3 show a with a swivel arm 17 in Connected frame 18 on which the drive unit 4 is arranged.
