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. The elevator car slides on rollers on the inside of angle iron of the frame. The elevator ropes are over two Deflection pulleys that are at the level of the stage fed to a rope drum and opened or closed in opposite directions settled.

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. Aus der Schrift JP 01267286 ist ein Aufzug mit Aufzugskabine und Gegengewicht und einem im Schachtkopf angeordneten Aufzugsantrieb bekannt geworden. Das Zug-/Tragseil verläuft von einem ersten Fixpunkt über eine am Gegengewicht angeordnete Umlenkrolle, dann über eine Treibscheibe des Aufzugsantriebes, dann über an der Unterseite der Aufzugskabine angeordnete Umlenkrollen und von diesen zu einem zweiten Fixpunkt.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. From the document JP 01267286 there is an elevator Elevator car and counterweight and one in Shaft head arranged elevator drive become known. The pull / suspension cable runs from a first fixed point a pulley arranged on the counterweight, then over a traction sheave of the elevator drive, then over at the Bottom of the elevator car arranged pulleys and from these to a second fixed point.

Diese Seilführung hat zum Nachteil, dass die Treibscheibe bzw. der Aufzugsantrieb aufrecht angeordnet werden muss, was wiederum einen höheren Schachtkopf zur Folge hat.The disadvantage of this rope guide is that the traction sheave or the elevator drive must be arranged upright, which in turn results in a higher shaft head.

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. Further It is advantageous that minimal 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.
