Description

Die Erfindung betrifft eine Aufzugsanlage mit einer Aufzugskabine und wenigstens einer Antriebseinheit und einem Ausgleichsgewicht mit Gegengewicht, wobei die Aufzugskabine und das Ausgleichsgewicht mittels wenigstens einem Tragmittel miteinander verbunden sind, und das wenigstens eine Tragmittel um wenigstens eine rotierende Scheibe oder Rolle umgelenkt ist.The invention relates to an elevator installation with an elevator car and at least one drive unit and a counterweight with counterweight, wherein the elevator car and the counterweight are connected to each other by means of at least one support means, and the at least one support means is deflected by at least one rotating disc or roller.

Bei bekannten Aufzugsanlagen ist der Antrieb, unabhängig von der Art des Antriebs, entweder in einem eigenen Maschinenraum angeordnet oder es handelt sich um einen so genannten maschinenraumlosen Aufzug, bei dem der Antrieb im Schacht unbeweglich, an der Aufzugskabine oder im Gegengewicht angeordnet ist, wie z.B. aus der US-A-6138799 bekannt. Die Anordnung im Gegengewicht weist mehrere Nachteile auf, z.B. dass eine spezielle Bauform des Antriebes erforderlich ist und dass der Raum über dem Antrieb im Gegengewicht nicht für den Einbau von Gewichten genützt werden kann und das Gegengewicht daher entsprechend größere Abmessungen aufweisen muss.In known elevator systems, the drive, regardless of the type of drive, either arranged in a separate machine room or it is a so-called machine room elevator in which the drive is immovable in the shaft, arranged on the elevator car or counterweight, such as from the US-A-6138799 known. The arrangement in the counterweight has several disadvantages, for example, that a special design of the drive is required and that the space above the drive in the counterweight can not be used for the installation of weights and the counterweight must therefore have correspondingly larger dimensions.

Bei den Tragmitteln kann es sich um Tragseile, Ketten, Riemen oder dergleichen handeln. Die rotierende Scheibe kann von einer Treibscheibe, einem Kettenrad, einem Riemenrad oder dergleichen gebildet sein.The suspension elements may be suspension cables, chains, belts or the like. The rotating disk may be formed by a traction sheave, a sprocket, a pulley or the like.

In Kenntnis dieser Gegebenheiten liegt der Erfindung die Aufgabe zugrunde, eine Aufzugsanlage der eingangs genannten Art zu schaffen, bei der der Materialbedarf für das Ausgleichsgewicht reduziert ist, die Abmessungen möglichst gering sind und bei der frei am Markt erhältliche Antriebe eingesetzt werden können.In view of these circumstances, the invention has for its object to provide an elevator system of the type mentioned, in which the material requirements for the balance weight is reduced, the dimensions are as small as possible and can be used in the freely available on the market drives.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Der Antrieb einer solchen Aufzugsanlage kann mit oder ohne Getriebe z. B. als Reibrad-, Riemen- oder Treibscheibenantrieb ausgeführt werden. Der Antrieb kann einen eintourigen, polumschalibaren oder einen geregelten Antriebsmotor aufweisen.The drive of such a lift system can be with or without gear z. B. as Reibrad-, belt or traction sheave drive. The drive can have a single-speed, pole-scarfable or a regulated drive motor.

Durch eine solche Verbindung von Antrieb und Gegengewicht zu einer Antriebseinheit und zu einem Ausgleichsgewicht kann das Gegengewicht entsprechend geringer dimensioniert werden. Die Trennung von rotierender Scheibe oder Rolle und Antrieb weist den weiteren Vorteil auf, dass der Zugang zum Antrieb zur Wartung oder zur Reparatur erleichtert ist.By such a combination of drive and counterweight to a drive unit and a balance weight, the counterweight can be dimensioned correspondingly smaller. The separation of the rotating disc or roller and drive has the further advantage that access to the drive for maintenance or repair is facilitated.

Definitionen gemäß EN 81-1:1998:

  • o Ausgleichsgewicht: Masse die der Energieeinsparung dadurch dient, dass sie die gesamte oder einen Teil der Masse des Fahrkorbes ausgleicht
  • o Gegengewicht: Masse, die die Treibfähigkeit sicherstellt
Definitions according to EN 81-1: 1998:
  • o Balance weight: mass that serves to save energy by balancing all or part of the mass of the car
  • o counterweight: mass that ensures the propulsion

In einer bevorzugten Ausführungsvariante ist vorgesehen, dass die Scheibe oder Rolle und der Antrieb durch ein Übertragungselement in Antriebsverbindung, vorzugsweise über einen Riemen, stehen. Es ist dann z.B. auch möglich, dass die Antriebsverbindung ein Zahnradantrieb oder ein Keilriemenantrieb ist.In a preferred embodiment, it is provided that the disc or roller and the drive by a transmission element in driving connection, preferably via a belt, stand. It is then e.g. also possible that the drive connection is a gear drive or a V-belt drive.

Eine solche Ausführung hat den Vorteil einer einfachen Verbindung von Antrieb und rotierender Scheibe oder Rolle.Such a design has the advantage of a simple connection of drive and rotating disc or roller.

Es ist vorgesehen, dass die Aufhängung der Aufzugskabine und die Aufhängung der Antriebseinheit derart erfolgt, dass die Fahrgeschwindigkeit der Aufzugskabine höher ist, als die der Antriebseinheit. Eine solche Ausführung kann z.B. dadurch realisiert werden, dass das eine Ende des über das Gegengewicht und über mindestens eine ortsfest gelagerte Rolle geführte Tragmittel ortsfest befestigt ist und das andere Ende des Tragmittels direkt an der Aufzugskabine befestigt ist.It is envisaged that the suspension of the elevator car and the suspension of the drive unit takes place in such a way that the traveling speed of the elevator car is higher than that of the drive unit. Such an embodiment may e.g. be realized that the one end of the over the counterweight and at least one stationarily mounted roller guided support means is fixed in place and the other end of the support means is attached directly to the elevator car.

Die Aufhängung kann in einer solchen Ausführungsvariante nach Art eines Flaschenzuges realisiert werden, d.h. bei einem einfachen Flaschenzug wird das Antriebsmittel bzw. Tragmittel an der Aufzugskabine befestigt und über zumindest eine ortsfeste Rolle und dann die rotierende Scheibe oder Rolle des Ausgleichsgewichtes geführt. Das gegenüberliegende Ende des Antriebs bzw. Tragmittels ist wiederum ortsfest, d.h. z.B. am oberen Ende des Aufzugschachtes fixiert. In diesem Fall ist ein einfacher 1:2 Flaschenzug realisiert. Das Ausgleichsgewicht mit der Antriebseinheit legt also den halben Weg zurück wie die Aufzugskabine. Ein daraus resultierender Vorteil ist, dass der Schacht für das Ausgleichsgewicht kürzer dimensioniert werden kann.The suspension can be realized in such an embodiment in the manner of a pulley, ie in a simple pulley the drive means or suspension is attached to the elevator car and at least one fixed roller and then guided the rotating disc or roller of the balance weight. The opposite end of the drive or support means is in turn stationary, ie, for example, fixed at the upper end of the elevator shaft. In this case, a simple 1: 2 pulley is realized. The balance weight with the drive unit thus lays halfway back as the elevator car. A resulting advantage is that the shaft for the balance weight can be made shorter.

Die Erfindung betrifft eine gattungsgemäße Aufzugsanlage, bei der der Antrieb und die rotierende Scheibe oder Rolle einen Teil oder das gesamte Ausgleichsgewicht bilden und mit dem Gegengewicht zu einer Antriebseinheit verbunden werden und die Aufhängung der Aufzugskabine und die Aufhängung der Antriebseinheit derart erfolgt, dass die Fahrgeschwindigkeit der Aufzugskabine höher ist, als die der Antriebseinheit. Dies wird bspw. dadurch erreicht, dass das das wenigstens eine Tragmittel über die Antriebseinheit und über mindestens eine ortsfest gelagerte Rolle geführt wird, wobei das eine Ende des Tragmittels ortsfest und das andere Ende des Tragmittels direkt an der Aufzugskabine befestigt ist.The invention relates to a generic elevator installation, in which the drive and the rotating disc or roller form part or all of the balance weight and are connected to the counterweight to a drive unit and the suspension of the elevator car and the suspension of the drive unit is such that the driving speed of Elevator car is higher than that of the drive unit. This is achieved, for example, in that the at least one suspension element is guided via the drive unit and via at least one stationarily mounted roller, wherein one end of the suspension element is stationary and the other end of the suspension element is fastened directly to the elevator car.

Eine derartige Aufhängung von Aufzugskabine und Antriebseinheit kann ebenfalls durch Flaschenzugmechanismen erfolgen. Günstig hat es sich herausgestellt, wenn der Antrieb und die rotierende Scheibe oder Rolle an der Oberseite des Gegengewichtes angebracht sind oder in einer anderen Ausführungsvariante, wenn der Antrieb und die rotierende Scheibe oder Rolle an der Unterseite des Gegengewichtes angebracht sind.Such a suspension of elevator car and drive unit can also be done by pulley mechanisms. Conveniently, it has been found that the drive and the rotating disc or roller are mounted on the top of the counterweight or in another embodiment, when the drive and the rotating disc or roller are mounted on the underside of the counterweight.

Eine derartige Anordnung von Antrieb und rotierender Scheibe oder Rolle hat den Vorteil einer besonders einfachen Montage am Gegengewicht. In einer Ausführungsvariante ist vorgesehen, dass die vom Antrieb angetriebene rotierende Scheibe oder Rolle an der Oberseite und der Antrieb an der Unterseite des Gegengewichtes angebracht sind oder dass die vom Antrieb angetriebene rotierende Scheibe oder Rolle an der Unterseite und der Antrieb an der Oberseite des Gegengewichtes angebracht sind. In dieser Ausführung ist der Zugang zum Antrieb aufgrund der Trennung zur rotierenden Scheibe oder Rolle erleichtert.Such an arrangement of drive and rotating disc or roller has the advantage of a particularly simple mounting on the counterweight. In one embodiment, it is provided that the driven by the drive rotating disc or roller on the upper side and the drive are mounted on the underside of the counterweight or that the driven by the drive rotating disc or roller attached to the underside and the drive at the top of the counterweight are. In this embodiment, access to the drive is facilitated due to the separation to the rotating disc or roller.

In einer weiteren Ausführungsvariante ist vorgesehen, dass der Antrieb des Gegengewichtes über ein Antriebselement an einer raumfest angeordneten Schiene angreift. Eine solche Anordnung hat z.B. den Vorteil, dass keine Verbindung von Antrieb zu rotierender Scheibe oder Rolle erforderlich ist. Insbesondere bei einer räumlichen Trennung von Antrieb und rotierender Scheibe oder Rolle ist dies vorteilhaft.In a further embodiment, it is provided that the drive of the counterweight engages via a drive element on a rail arranged fixed in space. Such an arrangement has e.g. the advantage that no connection from drive to rotating disk or roll is required. This is advantageous in particular in the case of a spatial separation of drive and rotating disk or roller.

Eine derartige Anordnung lässt sich bspw. dadurch realisieren, dass der Antrieb zwischen Antriebselement und Schiene über ein Reibrad erfolgt oder in einer anderen Ausführungsvariante dadurch, dass der Antrieb zwischen Antriebselement und Schiene über Ritzel und Zahnstange erfolgt. Der Antrieb erfolgt dann also nicht mehr über die rotierende Scheibe oder Rolle wie in einigen der oberen Ausführungsvarianten, sondern direkt über den Aufzugsschacht, in dem bspw. ein Reibrad des Antriebes an einer ortsfesten Schiene angreift und das Gegengewicht auf- und abwärts bewegt, wodurch auch die Aufzugskabine die entgegen gesetzte Ab- und Aufwärtsbewegung mitmacht. Ein solcher Reibradantrieb kann bspw. dadurch realisiert werden, dass zwei Räder eine Schiene in der Mitte einklemmen und durch gegengleiche Rotation der Räder erfolgt die Bewegung entlang der Schiene. Bei einem Antrieb mit Zahnstange und Ritzel greifen die Ritzel in die Zahnstange und bewegen dadurch das Gegengewicht nach oben oder nach unten. Beide Antriebsmechanismen können nach bekanntem Stand der Technik erfolgen, d.h. auch andere Antriebsmechanismen sind möglich.Such an arrangement can, for example, be realized in that the drive between the drive element and rail via a friction wheel or in another embodiment in that the drive between the drive element and rail via pinion and rack is done. The drive is then no longer on the rotating disc or roller as in some of the upper embodiments, but directly over the elevator shaft in which, for example, a friction wheel of the drive acts on a stationary rail and the counterweight moves up and down, which also the elevator car participates in the opposite upward and downward movement. Such a friction wheel drive can be realized, for example, in that two wheels clamp a rail in the middle and by opposite rotation of the wheels, the movement takes place along the rail. In a drive with rack and pinion, the pinions engage the rack and thereby move the counterweight up or down. Both drive mechanisms may be known in the art, i. Other drive mechanisms are possible.

In einer weiteren Ausführungsvariante ist vorgesehen, dass das wenigstens eine Tragmittel ein Seil ist. Ein solches Tragmittel ist besonders einfach in der Wartung und Montage. Ein derartiges Seil kann in an sich bekannter Weise ausgeführt sein bspw. als Stahlseil.In a further embodiment, it is provided that the at least one support means is a rope. Such a suspension element is particularly easy to maintain and assemble. Such a rope can be designed in a manner known per se, for example as a steel cable.
