Description

Die Erfindung betrifft eine Aufzugsanlage mit einem Kompensationsmittelstrang, der an einer Aufzugskabine und an einem Gegengewicht der Aufzugsanlage befestigt ist.The invention relates to an elevator installation with a compensation medium strand which is fastened to an elevator car and to a counterweight of the elevator installation.

Aufzugsanlagen umfassen eine Aufzugskabine und ein Gegengewicht. Die Aufzugskabine und das Gegengewicht sind an ein Tragmittel angehängt und abhängig voneinander bewegbar. Kabinen- bzw. gegengewichtseitig weist das Tragmittel je nach Position der Aufzugskabine innerhalb der Aufzugsanlage ein veränderliches Gewicht auf. Um dieses veränderliche Gewicht sowohl kabinenseitig als auch gegengewichtseitig zu kompensieren, umfasst die Aufzugsanlage zusätzlich ein Kompensationsmittel. Das Kompensationsmittel ist mittels seiner beiden Enden sowohl an der Aufzugskabine als auch am Gegengewicht fixiert. Im unteren Bereich der Aufzugsanlage bildet das Kompensationsmittel eine Schlaufe. Die längenspezifischen Massen des Tragmittels und des Kompensationsmittels sind im Wesentlichen gleich, um die genannte Gewichtsveränderung kompensieren zu können. Solche Kompensationsmittel können beispielsweise aus einem Seil, insbesondere einem Stahlseil, oder einem Riemen gebildet sein. Darüber hinaus können mehrere parallel verlaufende Kompensationsmittel einen Kompensationsmittelstrang bilden.Elevator systems include an elevator car and a counterweight. The elevator car and the counterweight are attached to a suspension and movable depending on each other. Cabin or counterweight side, depending on the position of the elevator car within the elevator installation, the suspension element has a variable weight. In order to compensate for this variable weight both on the cabin side and on the counterweight side, the elevator installation additionally comprises a compensating means. The compensation means is fixed by means of its two ends to both the elevator car and the counterweight. In the lower part of the elevator system, the compensating means forms a loop. The length-specific masses of the suspension element and of the compensating means are essentially the same in order to be able to compensate for the weight change mentioned. Such compensating means may be formed, for example, from a rope, in particular a steel cable, or a belt. In addition, a plurality of parallel compensation means can form a compensation medium strand.

US 3,991,856 A und JP S62235179 A zeigen derartige Kompensationsmittelstränge. US 3,991,856 A and JP S62235179 A show such compensating agent strands.

Um eine kontrollierte Bewegung des Kompensationsmittels bzw. des Kompensationsmittelstranges in der Aufzugsanlage zu bewirken, ist üblicherweise im unteren Bereich der Aufzugsanlage, also im Bereich der Schlaufe, eine Umlenkrolle angeordnet. An dieser Umlenkrolle wird der Kompensationsmittelstrang bzw. das Kompensationsmittel umgelenkt.In order to effect a controlled movement of the compensating means or of the compensation medium strand in the elevator installation, a deflection roller is usually arranged in the lower area of the elevator installation, that is to say in the region of the loop. At this deflection roller of the compensation medium strand or the compensation means is deflected.

Bei der Umlenkung eines solchen Kompensationsmittelstranges an der Umlenkrolle entsteht das Problem, dass einzelne Kompensationsmittel entlang einer freien Länge des Kompensationsmittelstranges ihre Positionen zueinander verändern können. Das führt an der Umlenkrolle zu unangenehmen Geräuschen bzw. zu vorzeitiger Abnutzung der einzelnen Kompensationsmittel und der Umlenkrolle.When deflecting such a compensation medium strand on the deflection roller, the problem arises that individual compensation means can change their positions relative to each other along a free length of the compensation medium strand. This leads to the pulley to unpleasant noise or premature wear of the individual compensation means and the pulley.

Es ist daher Aufgabe der Erfindung, eine Aufzugsanlage mit einer verbesserten Führung des Kompensationsmittelstranges an einer Umlenkeinrichtung bereitzustellen.It is therefore an object of the invention to provide an elevator installation with improved guidance of the compensation medium strand on a deflection device.

Die Aufgabe wird gelöst durch eine Aufzugsanlage umfassend eine Aufzugskabine, ein Gegengewicht und ein Tragmittel, an welchem Tragmittel das Gegengewicht und die Aufzugskabine derart angehängt sind, dass die Aufzugskabine und das Gegengewicht voneinander abhängig bewegbar sind, einen mehrere Kompensationsmittel umfassenden Kompensationsmittelstrang, welcher Kompensationsmittelstrang mit einem seiner beiden Enden an der Aufzugskabine und mit seinem anderen Ende am Gegengewicht aufgehängt ist, eine im unteren Bereich der Aufzugsanlage angeordnete Umlenkeinrichtung, wobei der Kompensationsmittelstrang durch die Umlenkeinrichtung umgelenkt und geführt ist, wobei der Kompensationsmittelstrang mindestens ein Verbindungselement aufweist, welches Verbindungselement an einem ersten der Kompensationsmittel fixiert ist und auf mindestens ein zweites der Kompensationsmittel derart wirkt, dass eine bezüglich der Aufzugsanlage relative Lageveränderung des ersten und des zweiten Kompensationsmittels zueinander eingeschränkt ist.The object is achieved by an elevator installation comprising an elevator car, a counterweight and a suspension element to which suspension means the counterweight and the elevator car are attached in such a way that the elevator car and the counterweight are mutually movable, a compensating means strand comprising a plurality of compensating means, which compensating means strand with a is suspended at its two ends to the elevator car and with its other end on the counterweight, arranged in the lower part of the elevator system deflecting device, wherein the Kompensationsmittelstrang is deflected and guided by the deflection, said Kompensationsmittelstrang has at least one connecting element, which connecting element at a first of the Compensating is fixed and acts on at least a second of the compensation means such that relative to the elevator installation relative change in position of the first and the second compensation is limited by means of each other.

Unterhalb der Aufzugskabine und des Gegengewichtes ist eine Umlenkeinrichtungen zum Umlenken des Kompensationsmittelstranges angeordnet, um unkontrollierte Bewegungen des Kompensationsmittelstranges innerhalb der Aufzugsanlage zu vermeiden. Durch die Verfahrbarkeit der Aufzugskabine mit teilweise hoher Geschwindigkeit entsteht jedoch das Problem, dass die einzelnen Kompensationsmittel des Kompensationsmittelstranges Relativbewegungen zueinander ausführen, was zu Problemen, wie beispielsweise eine überhöhte Abnutzung der Kompensationsmittel bzw. der Umlenkeinrichtung führen kann.Below the elevator car and the counterweight, a deflecting means for deflecting the compensation medium strand is arranged in order to avoid uncontrolled movements of the compensation medium strand within the elevator installation. Due to the mobility of the elevator car with partly high speed, however, the problem arises that the individual compensation means of the compensation medium strand perform relative movements relative to one another, which can lead to problems such as excessive wear of the compensation means or the deflection device.

Das Verbindungselement koppelt das erste Kompensationsmittel mit dem zweiten Kompensationsmittel, um die genannten Relativbewegungen zwischen diesen beiden Kompensationsmitteln einzuschränken oder zu verhindern. Darüber hinaus ist es möglich, gegebenenfalls die Relativbewegungen mindestens eines zwischen diesen beiden Kompensationsmitteln angeordneten weiteren Kompensationsmittels zu den beiden Kompensationsmitteln einzuschränken bzw. zu verhindern.The connecting element couples the first compensating means to the second compensating means to restrict or prevent said relative movements between these two compensating means. Moreover, it is possible, if appropriate, to restrict or prevent the relative movements of at least one further compensation means arranged between these two compensation means to the two compensation means.

Mittels des Verbindungselementes kann somit sichergestellt werden, dass die Kompensationsmittel in einer vorgegebenen Ausrichtung zueinander an der Umlenkeinrichtung umgelenkt und geführt werden, ohne dass störende Geräusche oder Schläge die Folge sind.By means of the connecting element can thus be ensured that the compensation means are deflected in a predetermined orientation to each other at the deflection and guided, without disturbing noises or blows are the result.

Das Verbindungselement ist vorzugsweise derart ausgebildet, dass eine spezifische Masse des Kompensationsmittelstranges durch Anbringen des Verbindungselementes nicht wesentlich beeinflusst wird. Auf diese Weise können unnötige unstetige Bewegungen bei der Führung des das Verbindungselement aufweisenden Abschnitts des Kompensationsmittelstranges an der Umlenkeinrichtung vermieden werden.The connecting element is preferably designed such that a specific mass of the compensating agent strand is not significantly influenced by attaching the connecting element. In this way, unnecessary unsteady movements in the leadership of the connecting element having portion of the compensation medium strand can be avoided at the deflection.

Bei einer Weiterbildung der Aufzugsanlage ist das Verbindungselement an dem zweiten Kompensationsmittel fixiert. Vorteilhaft ist, dass selbst eine mögliche Rotation des ersten Kompensationsmittels um seine eigene Längsachse weitestgehend verhindert wird.In a further development of the elevator installation, the connection element is fixed to the second compensation means. It is advantageous that even a possible rotation of the first compensating means about its own longitudinal axis is largely prevented.

Bei einer Weiterbildung der Aufzugsanlage ist das Verbindungselement von den beiden Enden des Kompensationsmittelstranges beabstandet. Derart wird sichergestellt, dass entlang der Länge des Kompensationsmittelstranges keine Verwindungen der einzelnen Kompensationsmittel zueinander auftreten.In a development of the elevator installation, the connection element is spaced from the two ends of the compensation medium strand. This ensures that no twisting of the individual compensation means occurs along the length of the compensation medium strand.

Bei einer Weiterbildung der Aufzugsanlage ist das Verbindungselement aus Kunststoff oder aus einem anorganischen Material gebildet. Die Verwendung von Kunststoff ermöglicht beispielhaft, dass die spezifische Masse des Kompensationsmittelstranges durch das Verbindungselement nur unwesentlich beeinflusst ist.In a development of the elevator installation, the connecting element is made of plastic or of an inorganic material. The use of plastic makes it possible by way of example that the specific mass of the compensating agent strand is only insignificantly influenced by the connecting element.

Bei einer Weiterbildung der Aufzugsanlage umfasst das Verbindungselement einen Befestigungsbereich zum Befestigen des Verbindungselementes an dem ersten Kompensationsmittel, wobei der Befestigungsbereich derart ausgebildet ist, dass der Befestigungsbereich das erste Kompensationsmittel nur teilweise umschliesst. Vorteilhaft ist, dass das Verbindungselement an dem betreffenden Kompensationsmittel befestigt werden kann, wenn die Kompensationsmittel des Kompensationsmittelstranges bereits in der Aufzugsanlage installiert sind.In a development of the elevator installation, the connection element comprises a fastening region for fastening the connection element to the first compensation means, wherein the fastening region is designed such that the fastening region only partially encloses the first compensation means. It is advantageous that the connecting element can be attached to the relevant compensation means when the compensation means of the compensation medium strand are already installed in the elevator installation.

Der Befestigungsbereich kann aus elastischem Kunststoff gebildet sein. Der auf diese Weise ausgebildete Befestigungsbereich kann an einen überwiegenden Teil des Umfanges des Kompensationsmittels grenzen, das heisst, ein solcher Befestigungsbereich den Querschnitt des Kompensationsmittels weitestgehend umschliesst, ohne dass die Installation des Verbindungselementes am Kompensationsmittel schon bei derThe attachment region may be formed of elastic plastic. The fastening region formed in this way can border on a predominant part of the circumference of the compensating means, that is to say that such a fastening region largely encloses the cross section of the compensating means, without the installation of the connecting element at the compensating means already at the

Herstellung des Kompensationsmittelstranges erfolgen muss.Preparation of the compensation medium strand must be made.

Bei einer Weiterbildung der Aufzugsanlage umschliesst der Befestigungsbereich im Moment einer Stellung des Verbindungselementes an der Umlenkeinrichtung im Wesentlichen die der Umlenkeinrichtung abgewandte Seite des ersten Kompensationsmittels. Auf diese Weise können Schläge an der Umlenkeinrichtung vermieden werden, die entstehen würden, wenn das Verbindungselement kurzzeitig während des Verfahrens der Aufzugskabine zwischen dem Kompensationsmittel und der Umlenkeinrichtung angeordnet wäre.In a further development of the elevator installation, the fastening area encloses, at the moment of a position of the connecting element on the deflection device, essentially the side of the first compensation means facing away from the deflection device. In this way, it is possible to avoid impacts on the deflection device which would occur if the connection element were arranged briefly between the compensation means and the deflection device during the process of the elevator cage.

Bei einer Weiterbildung der Aufzugsanlage weist die Umlenkeinrichtung eine Einlaufführung auf. Die Einlaufführung stellt eine zusätzliche Möglichkeit dar, dass die Kompensationsmittel in der vorgegebenen Ausrichtung zueinander an der Umlenkeinrichtung bewegt werden.In a further development of the elevator installation, the deflection device has an inlet guide. The inlet guide represents an additional possibility that the compensation means are moved in the predetermined orientation to each other at the deflection.

Bei einer Weiterbildung der Aufzugsanlage ist die Umlenkeinrichtung durch eine Umlenkrolle gebildet. Eine solche Umlenkrolle ermöglicht eine Umlenkung und Führung der Kompensationsmittel ohne überhöhte Reibungsverluste.In a further development of the elevator installation, the deflection device is formed by a deflection roller. Such a pulley allows a deflection and guidance of the compensation means without excessive friction losses.

Eine Weiterbildung der Aufzugsanlage umfasst ein zweites Verbindungselement, welches in Längsrichtung des Kompensationsmittelstranges von dem Verbindungselement beabstandet ist, welches zweite Verbindungselement an dem zweiten Kompensationsmittel und an einem dritten Kompensationsmittel des Kompensationsmittelstranges fixiert ist. Vorzugsweise ist das zweite Verbindungselement 20 bis 100 m vom ersten Verbindungselement beabstandet. Auf diese Weise kann gewährleistet werden, dass sowohl die einzelnen Kompensationsmittel ihre relative Lage zueinander beibehalten als auch die Aufzugsanlage kostengünstig ausgebildet ist.A further development of the elevator installation comprises a second connection element, which is spaced from the connection element in the longitudinal direction of the compensation medium strand, which second connection element is fixed to the second compensation means and to a third compensation means of the compensation medium strand. Preferably, the second connection element is spaced 20 to 100 m from the first connection element. In this way it can be ensured that both the individual compensation means maintain their relative position to one another and the elevator installation is designed to be cost-effective.
