Description

Die Erfindung betrifft einen Aufzug mit einer in einem Aufzugsschacht verfahrbaren Aufzugskabine und einem im Aufzugsschacht verfahrbaren Gegengewicht, wobei Aufzugskabine und Gegengewicht mittels mindestens eines Tragmittels verbunden sind und mittels mindestens eines Treibmittels auf und ab bewegbar sind, wobei das Treibmittel über eine mittels Antriebseinheit antreibbare Treibscheibe geführt ist gemäss der Definition des unabhängigen Patentanspruchs.The invention relates to an elevator with an elevator car movable in an elevator car and a counterweight movable in the elevator shaft, wherein elevator car and counterweight are connected by means of at least one support means and by means of at least one propellant movable up and down, wherein the propellant passed through a drivable drive unit by means of drive pulley is according to the definition of the independent claim.

Aus der Patentschrift GB 1 027 714 ist ein Aufzug bekannt geworden, bei dem die Aufzugskabine mittels über Umlenkrollen geführtem Tragmittel mit dem Gegengewicht verbunden ist. Auf und ab bewegt wird die Aufzugskabine bzw. das Gegengewicht mittels eines vom Tragmittel getrennten Treibmittels, das einenends am oberen Ende des Gegengewichts angreift, über eine obere und untere Umlenkrolle geführt ist und anderenends am unteren Ende des Gegengewichtes angreift. Das Treibmittel kann auch anstatt am Gegengewicht an der Aufzugskabine angreifen. Eine Antriebseinheit treibt das Treibmittel an.From the patent GB 1 027 714 an elevator has become known in which the elevator car is connected to the counterweight by means of deflection rollers guided suspension means. Moves up and down the elevator car or the counterweight by means of a separate from the support means propellant which engages at one end at the upper end of the counterweight, is guided over an upper and lower pulley and the other end engages the lower end of the counterweight. The propellant may also attack the elevator car instead of the counterweight. A drive unit drives the propellant.

Ein Nachteil der bekannten Einrichtung liegt darin, dass ein zusätzliches Treibmittel vorgesehen ist, das Treibmittel des Gegengewichtes und der Aufzugskabine antreibt.A disadvantage of the known device is that an additional propellant is provided which drives propellant of the counterweight and the elevator car.

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 Aufzugseinrichtung schaffen, bei der Tragmittel und Treibmittel getrennt sind und lediglich ein Treibmittel vorgesehen ist.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 an elevator device are separated in the suspension means and propellant and only a propellant is provided.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass mit der Verwendung von modernen Treibmitteln wie Riemen, Kunstfaserseilen (beispielsweise Aramidseile), Doppelseilen (beispielsweise zwei Kunstfaserseile mit einem gemeinsamen Mantel) oder ummantelten Stahlseilen Treibscheiben bzw. Umlenkrollen mit kleineren Durchmessern verwendbar sind, weil kleinere Biegeradien zulässig sind. Moderne Treibmittel sind allerdings teurer als herkömmliche Stahlseile. Mit der erfindungsgemässen Einrichtung ist es aber trotzdem möglich, insbesondere bei grossen Förderhöhen einen kostengünstigen Aufzug zu realisieren. Erreicht wird dies durch Aufteilung des Treibmittels in zwei Teile, nämlich in einen Treibteil und in einen Spannteil, wobei die beiden Teile mittels Schloss verbunden sind. Für den Treibteil wird ein modernes Treibmittel wie oben erwähnt und für den Spannteil ein herkömmliches Stahlseil verwendet. Damit können die Vorteile moderner Treibmittel und die Vorteile herkömmlicher Stahlseile auf einen Aufzug vereint werden. Weiter vorteilhaft ist, dass mit der Verwendung moderner Treibmittel die gesamte Antriebseinheit kleiner dimensioniert werden kann.The advantages achieved by the invention are essentially to be seen in that with the use of modern propellants such as belts, synthetic ropes (for example Aramidseile), double ropes (for example, two synthetic fiber cables with a common jacket) or jacketed steel ropes traction sheaves or pulleys with smaller diameters used are because smaller bending radii are allowed. Modern propellants, however, are more expensive than conventional steel cables. Nevertheless, with the device according to the invention, it is possible to realize a cost-effective elevator, in particular at high delivery heights. This is achieved by dividing the propellant in two parts, namely in a drive part and in a clamping part, wherein the two parts are connected by means of a lock. For the drive part is a modern propellant as mentioned above and used for the clamping part of a conventional steel cable. This combines the advantages of modern propellants with the advantages of conventional steel cables on a lift. Another advantage is that with the use of modern propellant the entire drive unit can be made smaller.

Bei der erfindungsgemässen Einrichtung ist eine Aufzugskabine und ein Gegengewicht mittels mindestens eines Tragmittels verbunden und werden mittels mindestens eines Treibmittels auf und ab bewegt, wobei das Treibmittel über eine mittels Antriebseinheit antreibbare Treibscheibe geführt ist und das Treibmittel aus einem Treibteil und aus einem Spannteil besteht, wobei die Teile verschiedenartig sind.In the device according to the invention, an elevator cage and a counterweight are connected by means of at least one suspension element and are moved up and down by means of at least one propellant, wherein the propellant is guided via a traction sheave drivable by means of a drive unit and the propellant consists of a drive part and a clamping part, wherein the parts are different.
