Abstract
Description
Gegenstand der Erfindung ist ein Aufzugssystem, wie in den Patentansprüchen definiert.The invention relates to an elevator system, as in the Claims defined.
Aufzugssysteme der erfindungsgemässen Art weisen üblicherweise eine Aufzugskabine und ein Gegengewicht auf, die in einem Aufzugsschacht oder entlang freistehender Führungseinrichtungen bewegbar sind. Zum Erzeugen der Bewegung weist das Aufzugssystem mindestens einen Antrieb mit mindestens je einer Treibscheibe auf, die über Trag- und Antriebsmittel die Aufzugkabine und das Gegengewicht tragen und die erforderlichen Antriebskräfte auf diese übertragen.Elevator systems of the inventive type usually have an elevator car and a counterweight that in an elevator shaft or along freestanding guide devices are movable. For generating the movement points the elevator system at least one drive with at least ever a traction sheave on the support and drive means carry the elevator car and the counterweight and the required driving forces transmitted to this.
Die Trag- oder Antriebsmittel werden im Folgenden als Tragmittel bezeichnet.The carrying or driving means are hereinafter referred to as Designated suspension.
Bei konventionellen Aufzugssystemen werden üblicherweise Stahlseile mit rundem Querschnitt als Tragmittel eingesetzt. Für neuere Aufzugssysteme kommen jedoch vermehrt flache, riemenartige Tragmittel zur Anwendung.In conventional elevator systems are usually Steel cables with round cross section used as a suspension element. However, newer elevator systems are increasingly shallow, belt-like suspension means for use.
Ein Aufzugssystem mit einem flachriemenartigen Tragmittel ist aus der PCT-Patentanmeldung WO 99/43593 bekannt. In der dort mit Fig. 6 dargestellten Ausführungsform enthält das Aufzugssystem eine Antriebsmaschine, die im Schachtraum oberhalb der Aufzugskabine angeordnet ist und über mindestens eine Treibscheibe auf mindestens einen flachen Tragmittelstrang wirkt, mit dem eine Aufzugskabine und ein auf deren Seite angeordnetes Gegengewicht auf- und abwärts bewegt werden können. Das flachriemenartige Tragmittel verläuft dabei von der einen Seite der Treibscheibe aus horizontal zu einer ersten Umlenkrolle, umläuft diese um 90°, erstreckt sich dann entlang der gegengewichtsseitigen Kabinenwand abwärts, umschlingt zwei auf je einer Seite unterhalb der Aufzugskabine angebrachte Kabinentragrollen um je 90° und verläuft entlang einer dem Gegengewicht abgewandten Kabinenwand aufwärts zu einem ersten, im oberen Bereich des Aufzugsschachts vorhandenen Tragmittelfixpunkt. Von der anderen Seite der Treibscheibe aus verläuft das Tragmittel horizontal zu einer zweiten Umlenkrolle, umläuft diese um 90°, erstreckt sich dann abwärts zur kabinenseitigen Seite der Peripherie einer Gegengewichtstragrolle, umschlingt diese um 180° und verläuft vertikal zu einem zweiten Tragmittelfixpunkt im Schachtkopfbereich.An elevator system with a flat belt-like suspension is known from PCT patent application WO 99/43593. In the there with Fig. 6 illustrated embodiment contains the Elevator system a prime mover working in the shaft room is arranged above the elevator car and over at least a traction sheave on at least one flat Tragmittelstrang acts, with an elevator car and a on its side arranged counterweight up and down can be moved. The flat belt-like suspension runs from one side of the traction sheave horizontally to a first pulley, this revolves around 90 °, then extends along the counterweight side Cabin wall down, wraps around two on each side Cabin idlers mounted below the elevator car each 90 ° and runs along a counterweight away Cabin wall up to a first, in the upper area the elevator shaft existing Tragmittelfixpunkt. Of the on the other side of the traction sheave, the suspension element extends horizontally to a second pulley, this revolves around 90 °, then extends down to the cabin side the periphery of a counterweight roll, wraps around this by 180 ° and runs vertically to a second Tragmittelfixpunkt in the shaft head area.
Ein solches Aufzugssystem hat dank der Anwendung eines flachriemenartigen Tragmittels den Vorteil, dass Treibscheiben sowie Umlenk- und Tragrollen mit wesentlich geringeren Durchmessern verwendet werden können, als dies bei Anwendung herkömmlicher Drahtseile zulässig wäre. Infolge des geringeren Treibscheibendurchmessers reduziert sich das an der Treibscheibe erforderliche Antriebsdrehmoment, wodurch eine Antriebsmaschine mit geringeren Abmessungen verwendet werden kann. Dank der allgemein geringeren Tragmittelscheiben-Durchmesser können einfachere und platzsparende Aufzugssysteme realisiert werden.Such an elevator system has thanks to the application of a Flat belt-like suspension means the advantage that traction sheaves as well as deflection and support rollers with much lower Diameters can be used than this when applying conventional wire ropes would be permissible. As a result of the lower Drive pulley diameter is reduced at the Traction sheave required drive torque, creating a Drive machine can be used with smaller dimensions can. Thanks to the generally smaller diameter of the support pulley can simpler and space-saving elevator systems will be realized.
Die in WO 99/43593 beschriebenen Aufzugssysteme weisen jedoch gewisse Nachteile auf.The elevator systems described in WO 99/43593 have however, certain disadvantages.
Infolge der geringen Treibscheibendurchmesser, und weil bei der Verwendung von Flachriemen als Tragmittel bekannte Massnahmen zur Verbesserung der Traktionsfähigkeit - beispielsweise Unterschneidung der Seilrillen an Treibscheiben für runde Tragmittel - nicht anwendbar sind, kann bei relativ grossem Gewichtsverhältnis zwischen voll beladener und leerer Aufzugskabine das Problem auftreten, dass die zwischen Treibscheibe und flachriemenartigem Traktionsmittel übertragbaren Traktionskräfte nicht ausreichen.Due to the small pulley diameter, and because at the use of flat belt known as a support means Measures to Improve Traction Capability - For example, undercut the rope grooves on traction sheaves for round suspension - not applicable, can at a relatively high weight ratio between full laden and empty elevator car the problem occur that between traction sheave and flat belt-like Traction means transferable traction forces are insufficient.
Ausserdem ist bekannt, dass bei der Verwendung von flachriemenartigen Tragmitteln ohne Profilierung der Lauffläche erhebliche Probleme mit der seitlichen Führung der Tragmittel auf der Treibscheibe, den Umlenkrollen und den Tragrollen auftreten. Erfahrungen haben gezeigt, dass das Risiko besteht, dass die Tragmittel an den üblicherweise an den Treibscheiben, den Umlenkrollen und den Tragrollen vorhandenen seitlichen Bordscheiben so stark reiben, dass die Tragmittel verletzt werden.It is also known that when using flat belt-like Supporting means without profiling of the tread significant problems with the lateral guidance of the suspension on the traction sheave, the pulleys and the idlers occur. Experience has shown that the risk exists that the suspension means to the usually s.den Traction sheaves, the pulleys and the idlers present rub the side flanges so hard that the Tragmittel be injured.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Aufzugssystem mit flachriemenartigen Tragmitteln zu schaffen, das die genannten Nachteile nicht aufweist.The present invention is based on the object To provide elevator system with flat belt-like support means which does not have the mentioned disadvantages.
Erfindungsgemäss wird die Aufgabe durch die im Patentanspruch
1 angegebenen Massnahmen gelöst. Vorteilhafte
Ausgestaltungen und Weiterbildungen der Erfindung gehen aus
den abhängigen Ansprüchen 2 bis 12 hervor.According to the invention, the object is achieved by the in the claim
1 measures resolved. advantageous
Embodiments and further developments of the invention are based
the
Die vorgeschlagene Lösung besteht im Wesentlichen darin, das
flachriemenartige Tragmittel mit ebenen Traktionsflächen
durch einen Keilrippenriemen zu ersetzen.
Ein Keilrippenriemen weist im Bereich seiner Traktionsfläche
mehrere in Riemen-Längsrichtung parallel verlaufende Rippen
und Rillen auf, deren Querschnitte keilförmig aufeinander
zulaufende seitliche Flanken zeigen. Beim Umlaufen der
Treibscheibe, an deren Peripherie ebenfalls Rippen und
Rillen vorhanden sind, welche zu denjenigen des Keilrippenriemens
komplementär sind, werden die keilförmigen Rippen
des Keilrippenriemens in die keilförmigen Rillen der
Treibscheibe gepresst. Dabei werden infolge der Keilform die
zwischen Treibscheibe und Keilrippenriemen auftretenden
Normalkräfte erhöht, so dass eine Verbesserung der Traktionsfähigkeit
zwischen Treibscheibe und Riemen resultiert.The proposed solution is essentially to replace the flat belt-like support means with flat traction surfaces by a V-ribbed belt.
A V-ribbed belt has, in the region of its traction surface, a plurality of ribs and grooves running parallel in the longitudinal direction of the belt, the cross-sections of which show wedge-shaped, mutually parallel lateral flanks. As the traction sheave rotates, at the periphery of which are also ribs and grooves complementary to those of the V-ribbed belt, the wedge-shaped ribs of the V-ribbed belt are pressed into the wedge-shaped grooves of the traction sheave. In this case, due to the wedge shape occurring between the traction sheave and V-ribbed belt normal forces are increased, so that an improvement in traction between the traction sheave and belt results.
Ausserdem gewährleistet das Ineinandergreifen der Rippen und Rillen des Keilrippenriemens in diejenigen der Scheiben und Rollen eine ausgezeichnete, auf mehrere Rippen- und Rillenflanken verteilte, seitliche Führung des Tragmittels.In addition, ensures the meshing of the ribs and Grooves the V-ribbed belt in those of the discs and Rolls an excellent, on multiple rib and groove flanks distributed, lateral guidance of the suspension element.
Das erfindungsgemässe Aufzugssystem umfasst selbstverständlich auch Ausführungen mit mindestens zwei parallel zueinander angeordneten Tragmittelsträngen (Keilrippenriemen).Of course, the elevator system according to the invention comprises also versions with at least two parallel to each other arranged suspension element strands (V-ribbed belt).
Gemäss einer bevorzugten Ausgestaltung der Erfindung sind die Querschnitte der Rippen und Rillen des Keilrippenriemens im Wesentlichen dreieckförmig oder trapezförmig. Keilrippenriemen mit dreieckförmigen oder trapezförmigen Rippen und Rillen sind besonders einfach und kostengünstig herstellbar.According to a preferred embodiment of the invention the cross sections of the ribs and grooves of the V-ribbed belt essentially triangular or trapezoidal. V-ribbed belts with triangular or trapezoidal ribs and Grooves are particularly easy and inexpensive to produce.
Ein vorteilhafter Kompromiss zwischen den Anforderungen an Laufruhe und an Traktionsfähigkeit wird erreicht, wenn die dreieckförmigen oder trapezförmigen Rippen und Rillen zwischen ihren seitlichen Flanken einen Winkel (b) aufweisen, der zwischen 80° und 100° liegt. An advantageous compromise between the requirements Smoothness and traction is achieved when the triangular or trapezoidal ribs and grooves have an angle (b) between their lateral flanks, which is between 80 ° and 100 °.
In einer besonders geeigneten Ausführungsform des erfindungsgemässen Aufzugssystems sind Keilrippenriemen vorhanden, bei denen der Winkel (b) zwischen den seitlichen Flanken der Rippen und Rillen 90° beträgt.In a particularly suitable embodiment of the inventive Elevator system are V-ribbed belts available, where the angle (b) between the lateral Flanks of the ribs and grooves is 90 °.
Keilrippenriemen, die besonders geringe Biegeradien zulassen, d. h., die für die Anwendung in Kombination mit Treibscheiben, Umlenkrollen und Tragrollen mit besonders kleinen Durchmessern geeignet sind, weisen auf einer mit Rippen und Rillen versehenen Seite Querrillen auf. Die beim Umlaufen von Scheiben und Rollen auftretenden Biegespannungen im Keilrippenriemen werden damit wesentlich reduziert.V-ribbed belts that allow particularly low bending radii d. h., for use in combination with Traction sheaves, pulleys and idlers with especially small diameters are suitable, with one on Ribs and grooves provide lateral grooves. The at Circulation of discs and rollers occurring bending stresses in V-ribbed belts are thus significantly reduced.
Zur Gewährleistung ausreichender Betriebssicherheit des Aufzugssystems sind mehrere zueinander parallel angeordnete, separate Keilrippenriemen als Tragmittel vorgesehen.To ensure sufficient reliability of the Elevator system are several parallel to each other, separate V-ribbed belt provided as a support means.
Besonders grosse Vorteile in Bezug auf das an der Treibscheibe erforderliche Drehmoment und damit die Abmessungen der Antriebsmaschine sowie in Bezug auf die Gesamtabmessungen einer Aufzugsanlage werden mit einem erfindungsgemässen Aufzugssystem erreicht, wenn mindestens die Treibscheiben, vorzugsweise jedoch auch die Umlenk- und Tragrollen, einen Aussendurchmesser von 70 mm bis 100 mm aufweisen. Bisherige Versuche führten zur Erkenntnis, dass mit Scheiben- und Rollendurchmessern von 85 mm den diversen Anforderungen und Belastungsgrenzen in optimaler Weise entsprochen werden kann.Especially big advantages in terms of the traction sheave required torque and thus the dimensions the prime mover and in relation to the overall dimensions an elevator system with an inventive Elevator system achieved if at least the traction sheaves, but preferably also the deflection and support rollers, a Outside diameter of 70 mm to 100 mm. Previous Attempts led to the realization that with disc and Roll diameters of 85 mm meet the various requirements and Load limits are optimally met can.
Eine weitere vorteilhafte Weiterbildung der Erfindung besteht darin, dass die Antriebsmaschine mit der Treibscheibenwelle und der Treibscheibe auf einem Träger montiert sind, der von einer der Kabinenführungsschienen und den beiden Gegengewichtsführungsschienen getragen wird. Damit wird erreicht, dass die auf die Treibscheibe und die Antriebsmaschine wirkenden Vertikalbelastungen grösstenteils über die Führungsschienen in die Fundamente des Aufzugsschachts geleitet werden, und nicht die Wände des Schachts belasten.A further advantageous embodiment of the invention is that the prime mover with the traction sheave shaft and the traction sheave mounted on a carrier that are from one of the cabin guide rails and the both counterweight guide rails is worn. In order to is achieved that on the traction sheave and the Drive machine acting vertical loads largely over the guide rails in the foundations of the elevator shaft and not the walls of the shaft strain.
Zusätzliche Betriebssicherheit wird gemäss einer der Ausführungsformen des erfindungsgemässen Aufzugssystems dadurch erreicht, dass auf dem die Antriebsmaschine stützenden Träger zusätzlich eine Bremseinheit montiert ist, die über die Treibscheibenwelle auf die Treibscheibe wirkt. Der Vorteil dieser Anordnung liegt darin, dass im Falle eines Maschinenbruchs die Bremswirkung auf die Treibscheibe nicht ausfällt.Additional operational safety is provided according to one of Embodiments of the elevator system according to the invention achieved in that on which the prime mover supportive Carrier in addition a brake unit is mounted, which acts on the traction sheave via the traction sheave shaft. Of the Advantage of this arrangement is that in case of Machine breaking the braking effect on the traction sheave not fails.
Ideale Einbauverhältnisse für die flachriemenartigen Tragmittel werden mit einer Ausführungsform der Erfindung erreicht, bei der die Antriebsmaschine mit der Treibscheibe oberhalb des durch die Aufzugskabine beanspruchten Raums angebracht ist, wobei die Ebene der Treibscheibe vertikal, rechtwinklig zu einer gegengewichtsseitigen Kabinenwand und etwa in der Mitte der Kabinentiefe angeordnet ist, und wobei die Vertikalprojektion der Treibscheibe auf der Gegengewichtsseite der Aufzugskabine ausserhalb von deren Vertikalprojektion liegt, ein Teil der Vertikalprojektion der Antriebsmaschine jedoch diejenige der Aufzugskabine überlagert. Eine solche Tragmittelanordnung erlaubt die Verwendung von Keilrippenriemen ohne Verdrehung von Tragmittelsträngen, die erforderlich ist, wenn aus Gründen der Platzeinsparung die Scheiben- und Rollenebenen in unterschiedlichen Richtungen angeordnet sind.Ideal installation conditions for the flat belt-like Tragmittel be with an embodiment of the invention achieved at which the prime mover with the traction sheave above the space occupied by the elevator car is attached, wherein the plane of the traction sheave vertically, perpendicular to a counterweight cabin wall and is arranged approximately in the middle of the cabin depth, and wherein the vertical projection of the traction sheave on the counterweight side the elevator car outside of their vertical projection is part of the vertical projection of the Drive machine, however, that superimposed on the elevator car. Such a suspension means arrangement allows the use V-ribbed belts without twisting suspension element strands, which is required if for reasons of space saving the disc and roller planes in different directions are arranged.
Eine erhebliche Einsparung von seitlich der Aufzugskabine erforderlichem Schachtraum wird dadurch ermöglicht, dass das Tragmittel sich von einem unterhalb der Treibscheibe vorhandenen Tragmittelfixpunkt aus abwärts erstreckt, eine Tragrolle des Gegengewichts umschlingt, sich von dieser aus zu der von der Aufzugskabine abgewandten Seite der Peripherie der Treibscheibe erstreckt, die Treibscheibe umschlingt, entlang einer gegengewichtsseitigen Kabinenwand abwärts verläuft und anschliessend eine übliche Kabinenunterschlingung bildet. Bei dieser Tragmittelanordnung ist auf der Gegengewichtsseite ein Abstand zwischen der Aufzugskabine und der Schachtwand erforderlich, der nur etwas grösser als der Durchmesser der Treibscheibe oder der Tragrolle ist. Bei Tragmittelanordnungen gemäss Fig. 5 und 6 des als Stand der Technik genannten Dokuments ist mindestens ein Abstand von zweifachem Scheibendurchmesser erforderlich.A considerable saving from the side of the elevator car required shaft space is thereby made possible that the Suspension means extending from below the traction sheave existing Tragmittelfixpunkt extends from downwards, a Supporting roller of the counterweight wraps around, extending from this to the side facing away from the elevator car side of the periphery extends the traction sheave, the traction sheave wraps around, down a counterweight-side cabin wall runs and then a usual Kabinenunterschlingung forms. In this support means arrangement is on the Counterweight side, a distance between the elevator car and the shaft wall required only slightly larger than the diameter of the traction sheave or the idler roller is. For support means arrangements according to FIGS. 5 and 6 of the stand the document referred to is at least one distance of twice the disc diameter required.
Gemäss einer weiteren Ausführungsform des erfindungsgemässen Aufzugssystems weist die Aufzugskabine im Bereich des unter der Aufzugskabine durchlaufenden Keilrippenriemens mindestens eine Führungsrolle für den Keilrippenriemen auf, die mit Rippen und Rillen versehen ist. Damit kann die obenstehend beschriebene vorteilhafte Tragmittelführung auch für einen Keilrippenriemen erreicht werden, der nur auf einer seiner Laufflächen Rippen und Rillen aufweist, die im Bereich der unterhalb der Aufzugskabine angebrachten Kabinentragrollen radial nach aussen gerichtet und durch letztere nicht geführt sind. According to a further embodiment of the inventive Elevator system has the elevator car in the area of the elevator car passing through V-ribbed belt at least a guide roller for the V-ribbed belt, the is provided with ribs and grooves. This can be the above described advantageous support means guide also for a V-ribbed belt can only be achieved on one its treads has ribs and grooves in the Area attached below the elevator car Kabinentragrollen radially directed outwards and through the latter are not managed.

Die vorliegende Beschreibung bezieht sich aus Gründen der Einfachheit stets auf ein Aufzugssystem mit einem Tragmittelstrang, mit einer Treibscheibe und mit jeweils einer Gegengewichts- oder Kabinentragrolle. Das erfindungsgemässe Aufzugssystem umfasst jedoch auch Ausführungen mit mindestens zwei parallel zueinander angeordneten Tragmittelsträngen (Keilrippenriemen), wobei die bei diesen Ausführungen ebenfalls mehrfach vorhandenen Scheiben und Rollen als mehrfach parallel vorhandene Einzelelemente oder als kombinierte Mehrfachelemente vorhanden sein können. Eine solche Mehrfachanordnung von Keilrippenriemen ist zum Nachweis ausreichender Systemsicherheit praktisch zwingend erforderlich.The present description refers to the reasons of Simplicity always on an elevator system with a suspension element strand, with a traction sheave and with one each Counterweight or cabin roll. The inventive However, elevator system also includes designs with at least two suspension element strands arranged parallel to one another (V-ribbed belt), which in these versions also several existing discs and rolls as multiple parallel existing individual elements or as Combined multiple elements may be present. A Such multiple arrangement of V-ribbed belt is for Proof of adequate system security practically mandatory required.

ist.
Eine solche Führungsrolle übernimmt die seitliche Führung
eines nur auf einer Lauffläche Rippen und Rillen aufweisenden
Keilrippenriemens 12. Ein solcher Keilrippenriemen 12
ist durch die Kabinentragrollen 7 nicht mit Hilfe der Rippen
und Rillen seitlich geführt, da diese beim Umlaufen dieser
Kabinentragrollen 7 radial nach aussen gerichtet sind. Eine
solche Führung ist jedoch nicht in jedem Fall erforderlich,
beispielsweise dann nicht, wenn die Kabinentragrollen 7 mit
Bordscheiben ausgerüstet oder ausreichend lang sind.Fig. 2 shows a particular embodiment of the lower loop of the

Bei der Ausführungsform gemäss Fig. 3 weisen die Rippen und Rillen einen dreieckförmigen und bei derjenigen nach Fig. 4 einen trapezförmigen Querschnitt auf. Der zwischen den Flanken einer Rippe oder einer Rille vorhandene Winkel b beeinflusst die Betriebseigenschaften eines Keilrippenriemens, insbesondere dessen Laufruhe und dessen Traktionsfähigkeit. Versuche haben ergeben, dass innerhalb gewisser Grenzen gilt, dass je grösser der Winkel b ist, desto besser die Laufruhe und desto schlechter die Traktionsfähigkeit werden. Vorteilhafte Eigenschaften betreffend Laufruhe und Traktionsfähigkeit werden gleichzeitig erreicht, wenn der Winkel b zwischen 80° und 100° liegt. Ein optimaler Kompromiss zwischen den gegensätzlichen Anforderungen wird mit Keilrippenriemen erreicht, bei denen der Winkel b bei etwa 90° liegt.In the embodiment according to FIG. 3, the ribs and Grooves a triangular and those of FIG. 4 a trapezoidal cross section. The between the Flanks of a rib or groove existing angles b influences the operating characteristics of a V-ribbed belt, in particular its smoothness and traction. Experiments have shown that within certain Limits holds that the larger the angle b, the better smoothness and poorer traction become. Advantageous properties regarding smoothness and Traction ability are achieved simultaneously when the Angle b is between 80 ° and 100 °. An optimal compromise between the conflicting requirements is with V-ribbed belt reaches, where the angle b at about 90 °.
Eine weitere Möglichkeit der Ausgestaltung des Keilrippenriemens
12 ist aus Fig. 4 erkennbar. Der Keilrippenriemen 12
weist neben den keilförmigen Rippen 23 und Rillen 24 auch
Querrillen 26 auf. Diese Querrillen 26 verbessern die Biege-Flexibilität
des Keilrippenriemens 12, so dass dieser mit
Treibscheiben, Trag- und Umlenkrollen zusammenwirken kann,
die extrem geringe Durchmesser aufweisen.Another possibility of the design of the V-ribbed
