Besonders bei Aufzügen, die zum Bewegen grösserer Lasten ausgelegt sind, kommt eine so genannte 4:1 Aufhängung zum Einsatz, bei der sich der von der Treibscheibe angetriebene Bereich des Trag- und/oder Treibelements, vier mal schneller als die Aufzugskabine bewegt. Eine solche Aufhängung ist in der
Bei derartigen 4:1 Aufhängungen, aber auch bei anderen Dispositionen treten Platzprobleme auf, besonders dann, wenn es sich um ein maschinenraumloses Aufzugssystem handelt. Je mehr Aufzugskomponenten im Schacht untergebracht werden müssen, desto wichtiger ist es, einen Ansatz zu finden, der Platz sparend ist.In such 4: 1 suspensions, but also in other dispositions space problems occur, especially if it is a machine room elevator system. The more lift components need to be accommodated in the shaft, the more important it is to find an approach that saves space.
Aufgabe der Erfindung ist es nun, einen verbesserten Aufzug der eingangs genannten Art vorzuschlagen, der sehr platzsparend in einem Schacht untergebracht werden kann.The object of the invention is therefore to propose an improved elevator of the type mentioned, which can be accommodated very space-saving in a bay.
Diese Aufgabe wird erfindungsgemäss gelöst durch die Merkmale der unabhängigen Ansprüche 1 und 10.This object is achieved according to the invention by the features of the
Die Verwendung von mehreren parallel zueinander angeordneten Flachriemen als Trag- und Treibmittel ermöglicht den Einsatz einer Treibscheibe sowie von Trag- und Umlenkrollen mit geringen Durchmessern. Ein geringer Treibscheibendurchmesser ermöglicht die Anwendung von Antriebsmotoren oder Antriebseinheiten mit geringen Abmessungen, und mit kleinen Trag- und Umlenkrollen kann der vorhandene Einbauraum optimal genutzt werden. Mit dem erfindungsgemässen Aufzug bzw. der Rollenanordnung wird erreicht, dass der seitlich neben der Aufzugskabine für die Umlenkung mehrerer paralleler Riemen erforderliche Einbauraum so gering wie möglich gehalten werden kann und einfache, klein bauende Rollengerüste verwendet werden können. Ausserdem ermöglicht es die Erfindung, die im Bereich der Unterschlingung auf jeweils einer Seite der Aufzugskabine vorhandenen Umlenkrollen entlang einer gemeinsamen Achse anzuordnen.The use of a plurality of mutually parallel flat belts as a carrier and propellant allows the use of a traction sheave and of supporting and deflection rollers with small diameters. A small pulley diameter allows the use of drive motors or drive units with small dimensions, and with small support and pulleys, the existing installation space can be optimally used. With the According to the invention, the elevator or the roller arrangement ensures that the installation space required laterally next to the elevator car for the deflection of a plurality of parallel belts can be kept as low as possible and simple, small-built roller stands can be used. In addition, the invention makes it possible to arrange the deflection rollers present in the region of the loop on each side of the elevator car along a common axis.
Bevorzugte Weiterbildungen und Einzelheiten des erfindungsgemässen Aufzugs sind durch die abhängigen Ansprüche 2 bis 9 definiert.Preferred developments and details of the elevator according to the invention are defined by the dependent claims 2 to 9.
Bei einer kostengünstigen Ausführungsform weist mindestens eine der fixen Rollengruppen für jeden der parallel angeordneten Riemen eine einzige zugeordnete Rolle auf, wobei jeder Riemen die zugeordnete Rolle um mehr als 90° umschlingt.In a cost effective embodiment, at least one of the fixed roller groups has a single associated roller for each of the parallel belts, each belt wraps around the associated roller by more than 90 °.
Vorteilhafterweise sind bei der vorstehend beschriebenen Ausführungsform die Rollen der zugeordneten verfahrbaren (Kabinen-) Rollengruppe entlang von schräg stehenden oder sich selbst entsprechend der Richtung der aufwärts führenden Riemenabschnitte einstellenden Achsen angeordnet.Advantageously, in the embodiment described above, the rollers of the associated movable (car) roller group are arranged along inclined or self-adjusting axes corresponding to the direction of the upwardly leading belt sections.
Bei einer bevorzugten Ausführungsform der Erfindung weist mindestens eine die Riemen umlenkende fixe Rollengruppe für jeden der parallel angeordneten Riemen zwei zugeordnete Rollen auf.In a preferred embodiment of the invention, at least one fixed roller group deflecting the belts has two associated rollers for each of the parallel belts.
Nach einer besonders bevorzugten Ausführungsform weist mindestens eine fixe Rollengruppe zwei Untergruppen von Rollen auf, wobei die Rollen dieser Untergruppen die parallel angeordneten Riemen um jeweils einen Teil des gesamten Umlenkwinkels umlenken. Die Rollen von jeweils einer der Untergruppen sind schräg übereinander angeordnet und weisen einen horizontalen Achsabstand zwischen zwei benachbarten Rollen auf, der vorzugsweise grösser ist als die Breite des Riemens. Mit dieser Ausführungsform wird erreicht, dass die Längsachsen der zwischen den fixen und verfahrbaren Kabinen-Rollengruppen angeordneten Riemenabschnitte in jeder Position der Aufzugs:kabine vertikal ausgerichtet bleiben.According to a particularly preferred embodiment, at least one fixed roller group has two subgroups of rollers, the rollers of these subgroups deflecting the belts arranged in parallel around one part of the entire deflection angle. The rollers of each one of the subgroups are arranged obliquely one above the other and have a horizontal center distance between two adjacent rollers, which is preferably greater than the width of the belt. With this embodiment It is achieved that the longitudinal axes of the arranged between the fixed and movable cab roller groups belt sections remain vertically aligned in each position of the elevator: cabin.
Zweckmässigerweise liegen die Rollen der fixen (mehrachsigen) Rollengruppen innerhalb zweier um die Rollenbreite beabstandeter paralleler Ebenen, wobei die Achsen der Rollen rechtwinklig zu diesen Ebenen ausgerichtet sind. Damit wird der für die Rollengruppe erforderliche Einbauraum minimiert.Conveniently, the rollers of the fixed (multiaxial) roller groups lie within two parallel planes spaced around the roller width, with the axes of the rollers being oriented at right angles to these planes. This minimizes the installation space required for the roller group.
Vorteilhafte Bedingungen in Bezug auf Befestigung und Wartung der fixen Rollengruppen ergeben sich dadurch, dass diese seitlich und/oder oberhalb der Aufzugskabine angeordnet sind und vorzugsweise an oder auf einer oder mehreren der Führungsschienen des Aufzugssystems befestigt sind.Advantageous conditions with regard to attachment and maintenance of the fixed roller groups result from the fact that they are arranged laterally and / or above the elevator car and are preferably attached to or on one or more of the guide rails of the elevator system.
Vorteile für das Einstellen und Nachspannen der Riemen resultieren daraus, dass die Fixpunkte aller Riemen unmittelbar benachbart und/oder auf einem Fixpunkt-Support angeordnet sind.
Durch Verbindung des Fixpunkt-Supports mit einer der Führungsschienen kann vermieden werden, dass die Belastung des Supports durch die Riemenkräfte ausschliesslich durch die Schachtwand der Aufzugsanlage aufgenommen werden muss.Advantages for adjusting and retightening the belts result from the fact that the fixed points of all belts are arranged immediately adjacent and / or on a fixed-point support.
By connecting the fixed point support with one of the guide rails can be avoided that the load of the support must be absorbed by the belt forces exclusively through the shaft wall of the elevator system.
Nach einer weiteren bevorzugten Ausführungsform sind die Riemen an mindestens einer ihrer Hauptflächen mit in Riemen-Längsrichtung verlaufenden Rippen und Rillen versehen, und die Treibscheibe wie auch die Trag- und Umlenkrollen weisen entlang des Umfangs ihrer Laufflächen entsprechend komplementäre Rippen und Rillen auf. Mit dieser Massnahme können die Führungseigenschaften zwischen den Rollen und dem Riemen wie auch die Traktionsfähigkeit zwischen Treibscheibe und Riemen wesentlich verbessert werden.According to another preferred embodiment, the belts are provided on at least one of their major surfaces with belt-longitudinal ribs and grooves, and the traction sheave as well as the support and deflection rollers have correspondingly complementary ribs and grooves along the circumference of their running surfaces. With this measure, the guiding properties between the rollers and the belt as well as the traction between the traction sheave and belt can be substantially improved.
Die Erfindung betrifft einen Aufzug mit mehreren parallel zueinander angeordneten flachen Riemen als Tragmittel.
Unter dem Begriff "mehrere Riemen" sind mindestens zwei und höchstens 8 Riemen zu verstehen.The invention relates to an elevator with a plurality of mutually parallel flat belt as a support means.
The term "multiple belts" means at least two and at most eight belts.
Unter dem Begriff "parallel angeordnete Riemen" ist dabei nicht eine geometrisch genau parallele Anordnung zu verstehen, sondern eine im Wesentlichen parallele Anordnung mehrerer funktionsgleicher Riemen.The term "parallel belt" is not to be understood as a geometrically exactly parallel arrangement, but a substantially parallel arrangement of a plurality of functionally identical belt.
Unter dem Begriff "flacher Riemen" sind Riemen mit im Wesentlichen rechteckigem Querschnitt zu verstehen, deren Breite grösser als deren Höhe (Dicke) ist. Unter diesen Begriff fallen insbesondere auch Riemen, die eine profilierte Lauffläche, beispiels-weise in Längsrichtung des Riemens verlaufende Keilrippen, aufweisen.The term "flat belt" is to be understood as meaning belts with a substantially rectangular cross section whose width is greater than their height (thickness).

Die Drehachsen A1 der vier co-axialen Rolleneinheiten verlaufen im Wesentlichen parallel zueinander. Gemäss Erfindung kommen mindestens n im Wesentlichen parallel zueinander verlaufende Riemen 16 zum Einsatz, mit n ≥ 2, wobei n eine ganze Zahl ist. Diese n Riemen 16 bilden eine so genannte Riemengruppe. Beim vorliegenden Ausführungsbeispiel umfasst die Riemengruppe n = 3 Riemen. Jeder der parallel zueinander verlaufenden Riemen 16 ist in der gezeigten Ausführungsform wie folgt angeordnet:
- von einem oberhalb des Bodenniveaus der in höchster Position stehenden
Aufzugskabine 14 vorhandenen Fixpunkt-Support 52 aus erstreckt sich der Riemen 16 abwärts und umschlingt eine erste Gegengewichts-Rolleneinheit 12.1. einer verfahrbaren Gegengewichts-Rollengruppe 12. - Anschliessend verläuft er entlang einer ersten Seite 14.1
der Aufzugskabine 14 vertikal aufwärts, wobei er sich um seine Längsmittelachse L verdreht und umschlingt zuerst eine erste individuelle Rolle 15.1 und dann eine zweite individuelle Rolle 15.2 der ersten fixen (mehrachsigen)Rollengruppe 15. - Nun erstreckt er sich vertikal abwärts, wobei er eine weitere Verdrehung um seine Längsmittelachse L erfährt und umschlingt eine zweite Gegengewichts-Rolleneinheit 12.2. der verfahrbaren Gegengewichts-
Rollengruppe 12. - Er verläuft erneut vertikal aufwärts und umschlingt eine Treibscheibe 11.1
einer Antriebseinheit 11. - Von der Treibscheibe aus wird er abwärts entlang der ersten Seite 14.1
der Aufzugskabine 14 zu einer ersten (co-axialen) Rolleneinheit 17.1 einer verfahrbaren Kabinen-Rollengruppe 17 geführt und verläuft anschliessend unterhalb des Aufzugsbodens 14.3 zu der zweiten (co-axialen) Rolleneinheit 17.2 der verfahrbaren Kabinen-Rollengruppe 17 und umschlingt diese. - Nach der Umschlingung der Rolleneinheit 17.2 erstreckt er sich wieder aufwärts entlang der zweiten Seite 14.2
der Aufzugskabine 14, wobei er eine weitere Verdrehung um seine Längsmittelachse L erfährt, und umschlingt eine erste individuelle Rolle 18.1.1 und anschliessend eine zweite individuellen Rolle 18.1.2 einer zweiten fixen (mehrachsigen)Rollengruppe 18. - Von hier aus verläuft er vertikal abwärts entlang der zweiten Seite 14.2
der Aufzugskabine 14 zu der dritten Rolleneinheit 17.3 der verfahrbaren Kabinen-Rollengruppe 17, wobei er erneut eine Verdrehung um seine Längsmittelachse L erfährt. - Er umschlingt die Rolleneinheit 17.3 und verläuft unterhalb des Aufzugsbodens 14.3 zu der vierten Rolleneinheit 17.4 der verfahrbaren Kabinen-
Rollengruppe 17, wonach er aufwärts entlang der ersten Seite 14.1der Aufzugskabine 14 zum Fixpunkt-Support 52 geführt und dort an seinem zweiten Ende fixiert ist.
- from a fixed
point support 52 provided above the floor level of theelevator car 14 in the highest position, thebelt 16 extends downwards and wraps around a first counterweight roller unit 12.1. a movablecounterweight roller group 12. - Subsequently, it runs vertically upwards along a first side 14.1 of the
elevator car 14, wherein it is rotated about its longitudinal central axis L and first wraps around a first one individual role 15.1 and then a second individual role 15.2 of the first fixed (multiaxial)role group 15. - Now it extends vertically downward, wherein it undergoes a further rotation about its longitudinal central axis L and wraps around a second counterweight roller unit 12.2. the movable
counterweight roller group 12. - It again runs vertically upwards and wraps around a traction sheave 11.1 of a
drive unit 11. - From the traction sheave, it is guided downwards along the first side 14.1 of the
elevator car 14 to a first (coaxial) roller unit 17.1 of a movablecabin roller group 17 and subsequently extends underneath the elevator floor 14.3 to the second (coaxial) roller unit 17.2 movablecab roller group 17 and wraps around this. - After wrapping around the reel unit 17.2, it again extends upwards along the second side 14.2 of the
elevator car 14, wherein it undergoes a further rotation about its longitudinal central axis L, and wraps around a first individual reel 18.1.1 and subsequently a second individual reel 18.1.2 second fixed (multiaxial)role group 18. - From here it runs vertically downwards along the second side 14.2 of the
elevator car 14 to the third roller unit 17.3 of the movablecabin roller group 17, wherein it again undergoes a rotation about its longitudinal center axis L. - It wraps around the roller unit 17.3 and runs below the elevator floor 14.3 to the fourth roller unit 17.4 of the movable
cab roller group 17, after which it is guided upwards along the first side 14.1 of theelevator car 14 to the fixedpoint support 52 and fixed there at its second end.
Die individuellen Rollen 18.1.1 - 18.2.3 der zweiten fixen (mehrachsigen) Rollengruppe 18 wie auch die individuellen Rollen 15.1.1 - 15.2.3 der ersten fixen (mehrachsigen) Rollengruppe 15, weisen Drehachsen A4 auf, die mindestens gegenüber den Drehachsen A1 der vier co-axialen Rolleneinheiten 17.1, 17.2 horizontal um ca. 90° geschwenkt sind.

Die im vorangehenden Abschnitt gemachten Aussagen betreffen generell die Anordnung der Riemen zwischen den Rollen der fixen Rollengruppen 15, 18 und den Rollen der mit der Aufzugskabine 14 oder dem Gegengewicht 13 verbundenen verfahrbaren Kabinen-Rollengruppen 17, 12. Sie gelten somit auch für die in

In dem zwischen der Treibscheibe 11.1 und der Rolleneinheit 17.1 der verfahrbaren Kabinen-Rollengruppe 17 liegenden Bereich 19.3 der Riemen können die n = 3 Riemen um ca. 180 Grad um ihre Längsmittelachsen verdreht sein, um zu ermöglichen, dass auf nur einer Seite strukturierte, beispielsweise mit Rippen und Rillen versehene Riemen sowohl die Treibscheibe 11.1 wie auch die Rolleneinheit 17.1 mit ihrer strukturierten Seite berühren.
Im vorstehend genannten Bereich 19.3 können die Riemen jedoch auch ohne Verdrehung installiert sein, beispielsweise, wenn die Riemen auf beiden Seiten strukturiert sind, oder wenn sie überhaupt keine Strukturierung an ihren Riemenflächen aufweisen und mit anderen Mitteln geführt sind.In the region 19.3 of the belts lying between the traction sheave 11.1 and the roller unit 17.1 of the movable
However, in the above-mentioned range 19.3, the belts may be installed without twisting, for example, when the belts are structured on both sides, or when they have no structuring on their belt surfaces and are guided by other means.
Eine oder beide der fixen Rollengruppen 15, 18 können an oder auf seitlichen Führungsschienen des Aufzugs 10 montiert sein, wobei vorzugsweise spezielle Montagemittel vorgesehen sind, die es erlauben die auftretenden Kräfte zentral (mittig) in die Führungsschienen einzuleiten.One or both of the fixed

Der Begriff "(co-axiale) Rolleneinheit einer verfahrbaren Rollengruppe" wurde gewählt, um den Unterschied zu der Anordnung der individuellen Rollen der (mehrachsigen) fixen Rollengruppen 15, 18 zu betonen. Die Rollen der (mehrachsigen) fixen Rollengruppen 15, 18 sind individuell gelagert, d.h. jede der Rollen einer fixen Rollengruppe hat eine eigene Drehachse. Die Stirnflächen der einzelnen Rollen liegen im Wesentlichen in einer Ebene und alle Rollenachsen verlaufen parallel zueinander und stehen senkrecht auf der genannten Ebene. Die individuellen Rollen 15.1.1 -15.2.3, 18.1.1 - 18.2.3 der mehrachsigen fixen Rollengruppen 15, 18 sind im montierten Zustand entweder gerade übereinander oder schräg übereinander (kaskadiert) angeordnet. Weitere Details einer beispielhaften mehrachsigen fixen Rollengruppe mit kaskadierten Rollen werden anhand von
Als Riemen werden vorzugsweise Riemen eingesetzt, deren eine Riemenhauptfläche strukturiert ist, um die Führung des Riemens auf den Rollen zu gewährleisten, bzw. die Traktionsfähigkeit zu verbessern. Die strukturierte Riemenhauptfläche kann zum Beispiel in Längsrichtung des Riemens verlaufende Rippen und Rillen aufweisen. Die Erfindung kann aber auch mit nicht-strukturierten Riemen realisiert werden.Belts are preferably used as belts whose one belt main surface is structured in order to ensure the guidance of the belt on the rollers or to improve traction capability. The structured belt main surface may, for example, have ribs and grooves extending in the longitudinal direction of the belt. The invention can also be realized with non-structured belt.
Wenn Riemen mit strukturierter Oberfläche verwendet werden, so sind die Mantelflächen der Treibscheibe und mindestens einiger der Trag- und Umlenkrollen vorzugsweise ebenfalls strukturiert, um die Führung des Riemens auf den Rollen zu gewährleisten, bzw. die Traktionsfähigkeit zwischen Treibscheibe und dem Riemen zu verbessern. Als Struktur weisen die Mantelflächen der Treibscheibe und der Rollen vorzugsweise Rippen und Rillen auf, die komplementär zu denjenigen des Riemens ausgeführt sind. Die Rippen und Rillen verlaufen dabei in Umfangsrichtung der Mantelfläche der Treibscheibe und der Rollen.If belts with a textured surface are used, the lateral surfaces of the traction sheave and at least some of the support and deflection rollers are preferably also structured to ensure the guidance of the belt on the rollers, or to improve the traction between the traction sheave and the belt. As a structure, the lateral surfaces of the traction sheave and the rollers preferably have ribs and grooves that are complementary to those of the belt. The ribs and grooves run in the circumferential direction of the lateral surface of the traction sheave and the rollers.
