Description

Die vorliegende Erfindung betrifft einen Aufzug für den Transport von Personen und/oder Gütern, mit mindestens einer Aufzugskabine, welche geführt an Führungsschienen oder Führungsmodulen entlang einer Schachttüren aufweisenden Wand eines Gebäudes auf und ab fahrbar ist und welche vorzugsweise mit einem Gegengewicht verbunden ist, wobei die Aufzugskabine angetrieben ist von einem Antriebsmodul mit mindestens einer Treibscheibe oder -rolle, welches über Tragorgane mit der Aufzugskabine in Verbindung steht.The present invention relates to an elevator for the transport of people and / or goods, with at least one elevator car, which is guided on guide rails or guide modules along a shaft doors wall of a building up and down mobile and which is preferably connected to a counterweight, said Elevator car is driven by a drive module with at least one traction sheave or pulley, which is connected via support members with the elevator car.

Aufgrund der Leistungsfähigkeit und Variabilität ist dieser Aufzugstyp sowohl für kleine, als auch für hohe Gebäude geeignet. Der Anwendungsbereich reicht von kleinen Warenaufzügen bis zu Bettenaufzügen für Krankenhäuser oder ähnliches.Due to its performance and variability, this type of lift is suitable for both small and tall buildings. The scope of application ranges from small goods lifts to bed lifts for hospitals or similar.

Bekannte Aufzüge der oben genannten Bauart, wie z.B. in der EP 631 967 beschrieben, weisen eine im Aufzugsschacht neben der Kabine befindliche Antriebseinheit auf. Dies erfordert entweder eine Verbreiterung des Schachtes über die ganze Schachthöhe oder die Verwendung spezieller, extrem flacher Antriebseinheiten mit hohen Herstellkosten. Nach einem anderen Vorschlag nach der noch unveröffentlichten EP-Anmeldung Nr. 96108133.8 wird ein Anbauaufzug der eingangs genannten Art beschrieben, wobei die Kabine mittels eines unterhalb der Kabine angeordneten Reibradantriebes als eine vertikal selbstfahrende Transporteinheit ausgebildet ist. Der Vorteil selbstfahrender Kabinen besteht darin, dass kein Maschinenraum benötigt wird und dass mehrere Kabinen im gleichen Schacht verkehren können. Andererseits muss der Antrieb permanent mitgeführt werden.Known elevators of the above type, as described for example in EP 631 967, have a drive unit located in the elevator shaft next to the car. This requires either a widening of the shaft over the entire shaft height or the use of special, extremely flat drive units with high production costs. According to another proposal according to the still unpublished EP application no. 96108133.8 a cultivation elevator of the type mentioned is described, wherein the cabin is formed by means of a arranged below the cab friction drive as a vertically self-propelled transport unit. The advantage of self-propelled cabins is that no machine room is needed and that several cabins can run in the same pit. On the other hand, the drive must be permanently carried.

Hier will nun die Erfindung für den Betrieb einer Aufzugskabine eine Lösung aufzeigen, bei der ebenfalls kein Maschinenraum benötigt wird und bei der die Antriebseinheit mit der Aufzugskabine nicht mitgeführt zu werden braucht. Dabei bleibt der modulare Aufbau erhalten, der die fabrikmässige Produktion von kompletten Aufzugssystemen mit verschiedenen Tragfähigkeiten und für verschiedene Gebäudehöhen erlaubt.Here now the invention for the operation of an elevator car will show a solution in which also no machine room is needed and in which the drive unit with the elevator car need not be carried. At the same time, the modular structure is preserved which allows the factory production of complete elevator systems with different capacities and for different building heights.

Die wie im Anspruch 1 gekennzeichnete Erfindung zeichnet sich u.a. dadurch aus, dass ein stationärer Antrieb platzsparend unter der Schachtdecke angeordnet ist und so weder zusätzlichen Schachtquerschnitt benötigt noch mit der Kabine mitgeführt werden muss. Die Last der Kabine und des Gegengewichts lässt sich gleichmässig auf die Führungen verteilen und muss nicht wie im Stand der Technik einseitig einer Führungsschiene zugeordnet werden.The invention as characterized in claim 1 is characterized i.a. characterized in that a stationary drive is arranged to save space under the shaft ceiling and so no additional shaft cross-section needs to be carried with the cab. The load of the car and the counterweight can be uniformly distributed on the guides and does not have to be assigned as one side of a guide rail as in the prior art.

Vorteilhafte Weiterbildungen und Verbesserungen sind in den abhängigen Ansprüchen aufgeführt.Advantageous developments and improvements are listed in the dependent claims.

Das Antriebsmodul wird von einem die beiden Führungsschienen oder Führungsmodule verbindenden Kopfmodul getragen oder ist als mittragendes Teil eines Antrieb-Kopfmoduls ausgebildet, so dass die resultierenden Kräfte über die Führungen in das Fundament geleitet werden.The drive module is carried by a head module connecting the two guide rails or guide modules, or is formed as a co-supporting part of a drive head module, so that the resulting forces are conducted via the guides into the foundation.

Eine Anordnung der Treibscheiben unmittelbar über den Führungsmodulen erspart jegliche zusätzlichen Umlenkrollen.An arrangement of traction sheaves immediately above the guide modules saves any additional pulleys.

Ein schlanker, langgestreckter Antrieb erfordert nur geringe Bauhöhe, sodass, wenn der Aufzug beispielsweise in einem bestehenden Schacht installiert wird, dieser Schacht antriebsbedingt praktisch nicht nach oben verlängert werden muss.A slender, elongated drive requires only a small height, so that if the elevator is installed, for example, in an existing shaft, this shaft has practically no need to be extended upward due to the drive.

Der Stationärantrieb kann, beispielsweise für eine Leistungsverdoppelung, in zwei Einzelantriebe aufgeteilt werden, wobei jeder der beiden Antriebe einem Führungsmodul zugeordnet wird und Doppel-Antrieb-Kopf- oder Fundamentmodule gebildet werden können.The stationary drive can, for example, for a power doubling, be divided into two individual drives, each of the two drives is assigned to a guide module and double drive head or foundation modules can be formed.

Vorteilhaft weist das Antriebsmodul zwei Antriebswellen mit je einer Treibscheibe auf.Advantageously, the drive module on two drive shafts, each with a traction sheave.

Durch eine gegeneinander entgegengesetzte Anordnung der Einzelantriebe am Kopfmodul wird eine um die Querachse ausgeglichene Belastung des Kopfmoduls erreicht.By a mutually opposite arrangement of the individual drives on the head module a balanced around the transverse axis load of the head module is achieved.

Das Antriebsmodul kann mit Führungsmodulen, Befestigungsmodulen und einem Kopf- oder Fundamentmodul zu einem selbsttragenden Rahmen zusammengefügt werden, welcher eine mit Lastwagen oder per Bahn transportierbare Einheit bildet.The drive module can be assembled with guide modules, mounting modules and a head or foundation module to form a self-supporting frame, which forms a transportable by truck or by rail unit.

In der Fig.1 ist mit 1 eine Gebäudewand bezeichnet, an welcher, geführt von zwei säulenartigen Führungsmodulen 10, eine Aufzugskabine 5 auf und ab fährt. Ein Schacht als baulicher Bestandteil eines Gebäudes und als Träger von Befestigungsarmaturen für Führungsschienen der Kabine und des Gegengewichtes sowie von weiteren aufzugsspezifischen Apparaten wird nicht unbedingt benötigt. Die Führungsmodule 10 erstrecken sich über mehrere Stockwerke 8 und sind wegen des vorgesehenen Strassentransportes maximal ca. 18 m lang. Durch Aneinanderfügen mehrerer Elemente können ohne weiteres auch höhere Gebäude bis 100 m und mehr damit ausgeführt werden.In FIG. 1, 1 designates a building wall on which, guided by two columnar guide modules 10, an elevator car 5 moves up and down. A shaft as a structural component of a building and as a carrier of mounting fittings for guide rails of the cabin and the counterweight and other elevator-specific apparatus is not necessarily needed. The guide modules 10 extend over several floors 8 and are due to the proposed road transport a maximum of about 18 m long. By joining several elements, higher buildings up to 100 m and more can easily be installed.

Die Aufzugskabine 5 weist Führungsrollen 17 an einem oberen Joch 4 und an einem unteren Joch 7, sowie eine Seilendbefestigung 20 am oberen Joch 4 auf. Das obere Joch 4 und das untere Joch 7 sind vertikal mit dem Fangrahmen 6 verbunden. Die Führungsmodule 10 sind mittels Befestigungsmodulen 11 bei den Stockwerken 8 mit dem Gebäude verbunden. Die Führungsmodule 10 sind unten mit einem Fundamentmodul 13 querverbunden und auf den Schachtboden abgestellt. Das Fundamentmodul 13 trägt ferner einen oder zwei Puffer 23. Oben sind die Führungsmodule 10 mit einem Kopfmodul 2 querverbunden, wobei hier das Kopfmodul 2 ein Antriebsmodul 12 trägt und in dieser Kombination als Antrieb-Kopfmodul 22 bezeichnet wird. Das Antriebsmodul 12 weist seitliche Treibscheiben 14 auf, über welche je Tragseile 3 geschlungen sind, die mit der Aufzugskabine 5 und mit den in den Führungsmodulen 10 laufenden Gegengewichten 9 über die zweiten Seilendbefestigungen 20 verbunden sind. Von den zwei Treibscheiben 14 ist in der Ansicht der Fig.1 nur eine davon sichtbar. Das gleiche gilt für die Führungsmodule 10 und die Gegengewichte 9. Die Führungsmodule 10 können als beliebig gestaltetes Profil ausgebildet sein, mit oder ohne Führungen für ein Gegengewicht.The elevator car 5 has guide rollers 17 on an upper yoke 4 and on a lower yoke 7, and a Seilendbefestigung 20 on the upper yoke 4. The upper yoke 4 and the lower yoke 7 are vertically connected to the catch frame 6. The guide modules 10 are connected by means of fastening modules 11 at the floors 8 to the building. The guide modules 10 are cross-connected below with a foundation module 13 and parked on the shaft floor. The foundation module 13 also carries one or two buffers 23. Above the guide modules 10 are cross-connected to a head module 2, in which case the head module 2 carries a drive module 12 and is referred to in this combination as a drive head module 22. The drive module 12 has lateral Traction sheaves 14, over which each support cables 3 are looped, which are connected to the elevator car 5 and with the running in the guide modules 10 counterweights 9 via the second Seilendbefestigungen 20. Of the two traction sheaves 14, only one of them is visible in the view of FIG. The same applies to the guide modules 10 and the counterweights 9. The guide modules 10 may be formed as an arbitrarily shaped profile, with or without guides for a counterweight.

In der Fig.2 ist der modular aufgebaute Aufzug in einem Aufzugsschacht 27 angeordnet. Es sind von oben gesehen weitere Einzelheiten des Antrieb-Kopfmoduls 22 erkennbar. Dieses besteht aus einem zwischen zwei parallelen Querträgern zentral angeordneten Antriebsmodul 12 mit einem Motor 19. Dieser weist beidseitig abgehende Antriebswellen 18 auf, an denen an den äusseren Enden je eine Treibscheibe 14 angebracht ist. Die Antriebswellen 18 sind, was in der schematischen Darstellung nicht ersichtlich ist, mit einem Schutzrohr versehen, wobei das Schutzrohr am äusseren Ende hinter der Treibscheibe 14 ein Wellenlager aufweist. Zwecks Abstützung dieser Lagerstelle ist das Schutzrohr an diesem äusseren Ende in eine entsprechende Ausnehmung im Führungsmodul 10 geführt, wobei so die Vertikalkraft der angehängten Last mit der Aufzugskabine 5 und dem Gegengewicht 9 in das knickfest dimensionierte Führungsmodul 10 geleitet wird. Durch diese Anordnung entstehen keine Biegekräfte in den Antriebswellen 18. Das Antriebsmodul 12 ist als mittragendes Teil des Antrieb-Kopfmoduls 22 ausgebildet und ersetzt so weitere versteifende Verbindungsstreben zwischen den Querträgern.2, the modular elevator is arranged in an elevator shaft 27. There are more details of the drive head module 22 seen from above recognizable. This consists of a between two parallel cross beams centrally arranged drive module 12 with a motor 19. This has on both sides outgoing drive shafts 18, to which at the outer ends depending on a traction sheave 14 is mounted. The drive shafts 18 are, which is not apparent in the schematic representation, provided with a protective tube, wherein the protective tube at the outer end behind the traction sheave 14 has a shaft bearing. In order to support this bearing point, the protective tube is guided at this outer end in a corresponding recess in the guide module 10, whereby the vertical force of the attached load with the elevator car 5 and the counterweight 9 is guided in the kink-resistant dimensioned guide module 10. By this arrangement, no bending forces in the drive shafts 18. The drive module 12 is formed as a co-supporting part of the drive head module 22 and thus replaces further stiffening connecting struts between the cross members.

Das Antriebsmodul 12 umfasst nebst dem Motor 19 eine nicht dargestellte Bremse und fallweise ein ebenfalls nicht dargestelltes Reduktionsgetriebe. Das Antriebsmodul 12 ist vorteilhafterweise aufgebaut wie in der EP 96107861.5, welche zum Bestandteil dieser Anmeldung erklärt wird, d.h. mit einer hohlen Rotorwelle ausgebildet, was zu einer schlanken, langgestreckten Bauart mit kleinem Durchmesser des Antriebs führt. Damit wird mit der zusätzlichen Verwendung kleiner Treibscheiben 14 von 150 bis 300 mm Durchmesser und vorzugsweise Aramidseilen nur sehr wenig horizontale Bauhöhe benötigt. Die abgehenden Tragseile 3 der Treibscheiben 14 führen praktisch ohne Schrägzug in das Zentrum der Führungsmodule 10 zu den Gegengewichten 9 auf der einen Seite und zu den Seilendbefestigungen 20 auf dem seitlichen Ausleger des Fangrahmens 6 der Aufzugskabine 5.The drive module 12 comprises in addition to the motor 19 a brake, not shown, and occasionally a likewise not shown reduction gear. The drive module 12 is advantageously constructed as in EP 96107861.5, which is explained as part of this application, ie with a hollow rotor shaft formed, resulting in a slim, elongated design with a small diameter of the drive. This is required with the additional use of small traction sheaves 14 of 150 to 300 mm in diameter and preferably aramid ropes only very little horizontal height. The outgoing support cables 3 of the traction sheaves 14 lead practically without diagonal train in the center of the guide modules 10 to the counterweights 9 on one side and the Seilendbefestigungen 20 on the side arm of the catch frame 6 of the elevator car. 5

Die Fig.3 und 4 zeigen im Prinzip die gleiche Anordnung des Antriebmoduls 12 wie bei den vorhergehenden Dispositionen. Der Unterschied zu diesen besteht jedoch darin, dass hier die Aufzugskabine 5 und die Gegengewichte 9 2:1 aufgehängt sind. Hierzu sind auf der Aufzugskabine 5 Umlenkrollen 15 und auf den Gegengewichten 9 Umlenkrollen 16 vorhanden. Ferner befinden sich die Seilendbefestigungen 20 am Antrieb-Kopfmodul 22. Mit dieser Disposition kann in vielen Fällen auf ein Reduktionsgetriebe im Antriebsmodul 12 verzichtet werden, wobei bei kleineren Kosten auch noch ein besserer Wirkungsgrad erzielt wird. Diese Disposition ist für jene Anwendungsfälle vorgesehen, wo grössere Lasten bei kleinen bis mittleren Geschwindigkeiten zu befördern sind.Figures 3 and 4 show in principle the same arrangement of the drive module 12 as in the previous dispositions. The difference to these, however, is that here the elevator car 5 and the counterweights 9 2: 1 are suspended. For this purpose, 5 pulleys 15 and on the counterweights 9 pulleys 16 are present on the elevator car. Furthermore, the Seilendbefestigungen 20 are located on the drive head module 22. With this disposition can be dispensed with in many cases on a reduction gear in the drive module 12, with a lower cost and a better efficiency is achieved. This disposition is intended for those applications where larger loads are to be carried at low to medium speeds.

Die Disposition gemäss den Fig.5 und 6 zeigen eine weitere Möglichkeit, wie der Leistungsbereich der erfindungsgemässen Aufzugsanlage nach oben noch mehr erweitert werden kann. Hierzu werden die Antriebsmodule 12 zweifach eingesetzt, je eines über dem linken und dem rechten Führungsmodul 10. Mittels einer geeigneten, nicht im einzelnen dargestellten Auslegerkonstruktion, werden die beiden Antriebsmodule 12 mit dem Kopfmodul 2 fest verbunden und bilden derart ein Doppelantrieb-Kopfmodul 24. In der gezeigten Darstellung sind die Aufzugskabine 5 und die Gegengewichte 9 zudem noch im Verhältnis 2:1 aufgehängt, was, bei halbierter Geschwindigkeit, die logische Verdoppelung der Tragkraft ergibt. In der gezeigten Darstellung sind die beiden Antriebsmodule 12 zueinander entgegengesetzt angeordnet. Dies bezweckt einen Lastdrehmomentausgleich um die Querachse beim Kopfmodul 2 bzw. Doppelantrieb-Kopfmodul 24. Bei der Verwendung des Antriebmoduls 12 für einen Doppelantrieb weist der Motor 19 nur eine abgehende Welle 18 mit einer Treibscheibe 14 auf.The disposition according to FIGS. 5 and 6 show a further possibility of how the power range of the elevator installation according to the invention can be extended even further upwards. By means of a suitable, not shown in detail cantilever construction, the two drive modules 12 are firmly connected to the head module 2 and thus form a dual-drive head module 24. In In the illustration shown, the elevator car 5 and the counterweights 9 are also suspended in a ratio of 2: 1, which, at half the speed, the logical doubling of the carrying capacity results. In the illustration shown, the two drive modules 12 are arranged opposite to each other. This aims at a load torque compensation about the transverse axis in the head module 2 or double drive head module 24. When using the drive module 12 for a double drive, the motor 19 has only one outgoing shaft 18 with a traction sheave 14.

Als letzte Variante zeigen die Fig.7 und 8 eine Disposition mit untenliegendem Antrieb. Hierbei wird das Antriebsmodul 12 mit dem Fundamentmodul 13 fest verbunden und die Tragseile 3 werden über Umlenkrollen 15 und 16 am Kopfmodul 2 zur Aufzugskabine 5 und zu den Gegengewichten 9 geführt, wobei 15 als Umlenkrolle für die Aufzugskabine 5 und 16 als Umlenkrolle für die Gegengewichte 9 vorgesehen ist. Die Umlenkrollen 15 und 16 sind mittels einer Befestigungskonsole 21 je an einem Führungsmodul 10 befestigt. Das Fundamentmodul 13 wird so zum Antrieb-Fundamentmodul 25. Gezeigt wird eine 1:1-Aufhängung für die Aufzugskabine 5 und die Gegengewichte 9. Es ist jedoch auch mit untenliegendem Antrieb möglich, eine 2:1-Aufhängung zu realisieren. Ebenso kann eine Verdoppelung der Antriebsleistung erreicht werden, indem, wie bei obenliegendem Antrieb, zwei Antriebsmodule 12 vorgesehen werden und so ein nicht dargestelltes Doppelantrieb-Fundamentmodul 26 bilden.As a last variant, Figures 7 and 8 show a disposition with bottom drive. Here, the drive module 12 is firmly connected to the foundation module 13 and the support cables 3 are guided over deflection rollers 15 and 16 on the head module 2 to the elevator car 5 and the counterweights 9, 15 as a guide pulley for the elevator car 5 and 16 as a deflection roller for the counterweights. 9 is provided. The deflection rollers 15 and 16 are each fastened to a guide module 10 by means of a fastening bracket 21. Shown is a 1: 1 suspension for the elevator car 5 and the counterweights 9. However, it is also possible with bottom drive to realize a 2: 1 suspension. Likewise, a doubling of the drive power can be achieved by, as in the overhead drive, two drive modules 12 are provided, thus forming a non-illustrated double drive foundation module 26.

Die gezeigten Beispiele zeigen die Anpassungsmöglichkeiten eines Modulsystems an einen weiten Bedürfnisbereich bezüglich Förderlast und Geschwindigkeit. Hierbei kann ein grosser Teil gleicher Module für alle Dispositionsvarianten verwendet werden. Die Leistunganpassungen bezüglich Tragkraft und Geschwindigkeit können durch die Anzahl der Antriebsmodule 12, mit und ohne Reduktionsgetriebe, sowie kombiniert mit der Aufhängungsart 1:1 oder 2:1 variiert werden. Bei Verwendung von Motoren 19 mit unterschiedlicher Leistung werden bezüglich Tragkraft und Geschwindigkeit noch grössere Anwendungsbereiche erschlossen.The examples shown show the adaptability of a modular system to a wide range of requirements in terms of conveying load and speed. Here a large part of the same modules can be used for all disposition variants. Capacity and speed performance adjustments can be varied by the number of drive modules 12, with and without reduction gearing, and combined with the 1: 1 or 2: 1 suspension type. When using motors 19 with different power even greater applications are developed in terms of carrying capacity and speed.

Bei Doppelantrieben wird mit einer entsprechenden Motorregelung, beispielsweise mit gleichen Drehzahl- und Drehmoment-Sollwerten, sichergestellt, dass auf beiden Seiten gleiche Zugkräfte herrschen. Als zwangsläufige Synchronisierung der beiden Antriebe kann mit geeigneten Mitteln, beispielsweise mit Kette und Kettenrädern, auch eine mechanische Koppelung vorgesehen werden.In the case of double drives, an appropriate motor control, for example with the same speed and torque setpoints, ensures that the same tensile forces prevail on both sides. As a positive synchronization of the two drives can be provided with suitable means, such as chain and sprockets, a mechanical coupling.

Die schlanke, langgestreckte Form des Antrieb-Kopfmoduls 22 bzw. Antrieb-Fundamentmoduls 25 macht es möglich, die Führungsmodule 10 mit sehr kurzen Befestigungsmodulen 11 ganz nahe am Gebäude anzuordnen, wobei dann die auftretenden Horizontalkräfte von der Gebäudestruktur aufgenommen werden. Damit ist das vorliegende Modulsystem auch für die Realisierung von Rucksackaufzügen geeignet.The slim, elongate shape of the drive head module 22 or drive foundation module 25 makes it possible to arrange the guide modules 10 with very short mounting modules 11 very close to the building, in which case the horizontal forces occurring are absorbed by the building structure. Thus, the present modular system is also suitable for the realization of backpack lifts.

Ein Einbau des erfindungsgemässen Aufzugs in einen Schacht 27 ergibt keine Aenderung der modulmässigen Disposition. Vorhandene Schachtwände dienen dann nur als Umwehrung und werden nicht mit Befestigungsarmaturen belastet. Der Aufzug wird kann als komplett vorgefertigte Einheit herangeführt werden, von oben in den noch offenen Schacht 27 hinabgelassen und dann an dessen Schachttürwand befestigt werden.An installation of the elevator according to the invention into a shaft 27 does not result in a change in the modular disposition. Existing shaft walls then serve only as a barrier and are not burdened with fastening fittings. The elevator can be brought as a completely prefabricated unit, lowered from above into the still open shaft 27 and then attached to the shaft door wall.
