Dabei bleibt der modulare Aufbau erhalten, der die fabrikmässige Produktion von kompletten Aufzugssystemen mit verschiedenen Tragfähigkeiten und für verschiedene Gebäudehöhen erlaubt.The invention described in more detail below is intended for operation show a solution to an elevator car that also does not Machine room is needed and the drive unit with the elevator car does not need to be carried. That remains get the modular structure, which is the factory production of complete elevator systems with different capacities and allowed for different building heights.

JP 60-150 149 Offenbart einen Aufzug gemäss Oberbegriffs Anspruchs 1.JP 60-150 149 discloses an elevator according to the preamble Claim 1.

Die Erfindung ist im Anspruch 1 gekennzeichnet und zeichnet sich unter anderem dadurch aus, dass ein stationärer Antrieb als Bestandteil des Modulsystems vorgesehen ist und als solches einen Antrieb-Kopfträger oder einen Antrieb-Fundamentträger bildet.The invention is characterized in claim 1 and stands out among other things from the fact that a stationary drive as Part of the module system is provided and as such one Forms drive head girder or a drive foundation girder.

Vorteilhafte Weiterbildungen und Verbesserungen des Aufzugs nach Anspruch 1 sind in den weiteren Ansprüchen aufgeführt.Advantageous further developments and improvements to the elevator Claim 1 are listed in the further claims.

Die Ausbildung des Antriebs, insbesondere des Antriebsgehäuses als tragendes oder mittragendes Teil des Kopfträgers erspart aufwendige Kopfträgerkonstruktionen.The design of the drive, especially the drive housing as supporting or supporting part of the head carrier is spared elaborate head support constructions.

Die Abstützung der auf die Treibscheibe einwirkenden Vertikalkräfte über ein Schutzrohr direkt in die Führungsschienen führt zu einem optimalen Kraftfluss ohne funktionell entbehrliche Stukturbauteile. Vorzugsweise ist das Schutzrohrende ohne zusätzliche Bauteile in einer Oeffnung der Führungsschienen abgestützt.The support of those acting on the traction sheave Vertical forces via a protective tube directly into the guide rails leads to an optimal flow of power without functionally unnecessary Stukturbauteile. The protective tube end is preferably without additional components in an opening of the guide rails supported.

Der als Antrieb-Kopfträger oder Antrieb-Fundamentträger ausgebildete Stationärantrieb weist zwei Antriebswellen mit je einer Treibscheibe auf, was bei symetrischer Lastverteilung jegliche Umlenkrollen erspart. Den gleichen Zweck verfolgt die Anordnung der Treibscheiben unmittelbar über die Führungsschienen.The one as a drive head support or drive foundation support trained stationary drive has two drive shafts each a traction sheave on what with symmetrical load distribution spared any pulleys. It has the same purpose Arrangement of the traction sheaves directly above the guide rails.

Ein schlanker, langgestreckter Antrieb erfordert nur geringe Bauhöhe, sodass der Schacht antriebsbedingt nicht verlängert werden muss.A slim, elongated drive requires only little Height, so that the shaft is not extended due to the drive must become.

Der Stationärantrieb kann, beispielsweise für eine Leistungsverdoppelung, in zwei Einzelantriebe aufgeteilt werden, wobei jeder der beiden Antriebe einer Führungsschiene zugeordnet wird und Doppel-Antrieb-Kopf- oder -Fundamentträger gebildet werden können.The stationary drive can, for example for a Performance doubling, divided into two individual drives, each of the two drives assigned to a guide rail is made and dual drive head or foundation beams can be.

Ein Antrieb-Kopfträger oder ein Antrieb-Fundamentträger ist mit Führungsschienen, Befestigungen und einem Kopf- oder Fundamentträger zu einem selbsttragenden Rahmen zusammenfügbar, welcher eine mit Lastwagen oder per Bahn transportierbare Einheit bildet.A drive head support or a drive foundation support is included Guide rails, fasteners and a head or Foundation beams can be assembled into a self-supporting frame, which is a unit that can be transported by truck or train forms.

Durch eine gegeneinander entgegengesetzte Anordnung der Einzelantriebe am Kopfträger wird eine um die Querachse ausgeglichene Belastung des Kopfträgers erreicht.

In Fig.1 ist mit 1 ein Aufzugsschacht bezeichnet, in welchem, geführt von zwei säulenartigen Führungsschienen 10, eine Aufzugskabine 5 auf und ab fährt. Die als Hohlprofil ausgebildeten Führungsschienen 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 ausgestattet werden.In FIG. 1, 1 denotes an elevator shaft, in which guided by two columnar guide rails 10, one Elevator car 5 moves up and down. The trained as a hollow profile Guide rails 10 extend over several floors 8 and are a maximum of approx. 18 m due to the planned road transport long. By joining several elements together you can easily even higher buildings up to 100 m and more can be equipped with it.

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 Führungsschienen 10 sind mittels Befestigungen 11 bei den Stockwerken 8 mit dem Gebäude verbunden. Die Führungsschienen 10 sind unten mit einem Fundamentträger 13 querverbunden und auf den Schachtboden abgestellt. Der Fundamentträger 13 trägt ferner einen oder zwei Puffer 23. Oben sind die Führungsschienen 10 mit einem Kopfträger 2 querverbunden, wobei hier der Kopfträger 2 einen Antrieb 12 trägt und in dieser Kombination als Antrieb-Kopfträger 22 bezeichnet wird. Der Antrieb 12 weist zwei seitliche Treibscheiben 14 auf, über welche je Tragseile 3 geschlungen sind, die mit der Aufzugskabine 5 und mit den in die Führungsschienen 10 laufenden Gegengewichten 9 über Seilendbefestigungen 20 verbunden sind. Von den beiden Treibscheiben 14 ist in der Ansicht der Fig.1 nur eine sichtbar. Das gleich gilt für die Führungsschienen 10 und die Gegengewichte 9. Die Führungsschienen 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 rope end attachment 20 on upper yoke 4. The upper yoke 4 and the lower yoke 7 are vertically connected to the catch frame 6. The guide rails 10 are by means of attachments 11 on the floors 8 with the Connected building. The guide rails 10 are with a bottom Foundation support 13 cross-connected and on the shaft floor switched off. The foundation support 13 also carries one or two Buffers 23. Above are the guide rails 10 with a head support 2 cross-connected, here the head support 2 a drive 12 carries and in this combination as drive head support 22nd referred to as. The drive 12 has two lateral traction sheaves 14, over which each suspension cable 3 is looped, with the Elevator car 5 and with those running in the guide rails 10 Counterweights 9 are connected via rope end fastenings 20. Of the two traction sheaves 14 is only one in the view of FIG visible. The same applies to the guide rails 10 and Counterweights 9. The guide rails 10 can be any designed profile be formed with or without guides for a counterweight.

In Fig.2 sind von oben gesehen weitere Einzelheiten des Antrieb-Kopfträgers 22 erkennbar. Dieses besteht aus einem zwischen zwei parallelen Querträgern zentral angeordneten Antrieb 12 mit einem Motor 19. Dieser weist beidseitig abgehende Antriebswellen 18 auf, an denen an den äusseren Enden je eine Treibscheibe 14 angebracht ist. Bei entsprechender Ausbildung des Motor- bzw. In FIG. 2, further details of the drive head carrier are seen from above 22 recognizable. This consists of one between two parallel cross members centrally arranged drive 12 with a Motor 19. This has drive shafts 18 coming out on both sides, on each of which a traction sheave 14 is attached at the outer ends is. With appropriate training of the engine or

Antriebsgehäuses kann der Antrieb auch selbst den Kopfträger, also die Verbindung zwischen den beiden Führungsschienen (10) bilden. Die Antriebswellen 18 sind mit einem feststehenden Schutzrohr 18' versehen, welches am äusseren Ende vor der Treibscheibe 14 ein die Antriebswelle 18 aufnehmendes Wellenlager aufweist. Zwecks Abstützung dieser Lagerstelle ist das Schutzrohr 18' an diesem äusseren Ende in eine entsprechende Ausnehmung in der Führungsschiene 10 geführt, wobei so die Vertikalkraft der angehängten Last mit der Aufzugskabine 5 und dem Gegengewicht 9 in die knickfest dimensionierte Führungsschiene 10 geleitet wird. Durch diese Anordnung entstehen praktisch keine Biegekräfte in den Antriebswellen 18. Der Antrieb 12 und davon vorzugsweise das Schutzrohr 18' ist als mittragendes Teil des Antrieb-Kopfträgers 22 ausgebildet und ersetzt so weitere versteifende Verbindungsstreben zwischen den Querträgern.Drive housing, the drive itself can also be the head support form the connection between the two guide rails (10). The drive shafts 18 are provided with a fixed protective tube 18 ' provided which at the outer end in front of the traction sheave 14 a Has drive shaft 18 receiving shaft bearing. For the purpose of Supporting this bearing point is the protective tube 18 'on this outer end in a corresponding recess in the Guide rail 10 out, so the vertical force of the attached load with the elevator car 5 and the counterweight 9 in the kink-resistant guide rail 10 is guided. With this arrangement there are practically no bending forces in the Drive shafts 18. The drive 12 and preferably that Protective tube 18 'is a load-bearing part of the drive head carrier 22 trained and thus replaced other stiffening Connection struts between the cross beams.

Der Antrieb 12 umfasst nebst dem Motor 19 eine nicht dargestellte Bremse und fallweise ein ebenfalls nicht dargestelltes Reduktionsgetriebe. Der Antrieb 12 ist zweckmässigerweise aufgebaut wie in der EP 96107861.5, d.h. mit einer hohlen Rotorwelle ausgebildet, was zu einer schlanken 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 Führungsschienen 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 12 includes, in addition to the motor 19, a not shown Brake and occasionally a not shown Reduction gear. The drive 12 is expedient constructed as in EP 96107861.5, i.e. with a hollow Rotor shaft formed, resulting in a slim design with small Diameter of the drive leads. So that with the additional Use of small traction sheaves 14 from 150 to 300 mm in diameter and preferably aramid ropes only very little horizontal height needed. Guide the outgoing suspension cables 3 of the traction sheaves 14 practically without inclined pull into the center of the guide rails 10 the counterweights 9 on one side and to the Rope end fastenings 20 on the side arm of the Frame 6 of the elevator car 5.

Die Fig.3 und 4 zeigen im Prinzip die gleiche Anordnung des Antriebs 12 wie bei der vorhergehenden Disposition. Der Unterschied zu dieser besteht jedoch darin, dass hier die Aufzugskabine 5 und die Gegengewichte 9 im Verhältnis 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-Kopfträger 22. Mit dieser Disposition kann in vielen Fällen auf ein Reduktionsgetriebe im Antrieb 12 verzichtet werden, wobei bei geringeren 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.3 and 4 show in principle the same arrangement of the Drive 12 as in the previous disposition. The The difference to this, however, is that here the Elevator car 5 and the counterweights 9 in a ratio of 2: 1 are hung. For this purpose there are 5 pulleys on the elevator car 15 and on the counterweights 9 pulleys 16 available. Further are the rope end fastenings 20 on the drive head carrier 22. In many cases, this disposition can lead to a Reduction gear in the drive 12 are omitted, with lower costs, even better efficiency becomes. This disposition is intended for those use cases where larger loads at low to medium speeds too are promoted.

Die Disposition gemäss den Fig.5 und 6 zeigen eine weitere Möglichkeit, wie der Leistungsbereich der erfindungsgemässen Aufzugsanlage nach oben noch erweitert werden kann. Hierzu werden die Antriebe 12 zweifach eingesetzt, je eines über der linken und dem rechten Führungsschiene 10. Mittels einer geeigneten, nicht im einzelnen dargestellten Auslegerkonstruktion, werden die beiden Antriebe 12 mit dem Kopfträger 2 fest verbunden und bilden derart ein Doppelantrieb-Kopfträger 24. In der gezeigten Darstellung sind die Aufzugskabine 5 und die Gegengewichte 9 zudem noch im Verhältnis 2:1 aufgehängt, was, bei halbierter Geschwindigkeit, eine Verdoppelung der Tragkraft ergibt. In der gezeigten Darstellung sind die beiden Antriebe 12 zueinander entgegengesetzt angeordnet. Dies bewirkt einen Lastdrehmomentausgleich um die Querachse beim Kopfträger 2 bzw. Doppelantrieb-Kopfträger 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 another one Possibility of how the performance range of the invention Elevator system can still be expanded upwards. To do this the drives 12 used twice, one each over the left and the right guide rail 10. Using a suitable, not in single boom construction shown, the two Drives 12 are firmly connected to the head support 2 and form in this way a dual drive head carrier 24. In the illustration shown the elevator car 5 and the counterweights 9 also in Ratio 2: 1 suspended, which, at half the speed, doubling the load capacity results. In the shown Representation, the two drives 12 are opposite to each other arranged. This causes a load torque balance around the Transverse axis for head support 2 or double drive head support 24. At the use of the drive module 12 for a double drive the motor 19 has only one outgoing shaft 18 with a traction sheave 14 on.

Als letzte Variante zeigen die Fig.7 und 8 eine Disposition mit untenliegendem Antrieb. Hierbei wird der Antrieb 12 mit dem Fundamentträger 13 fest verbunden und die Tragseile 3 werden über Umlenkrollen 15 und 16 am Kopfträger 2 zur Aufzugskabine 5 und zu den Gegengewichten 9 geführt, wobei die Umlenkrolle 15 für die Aufzugskabine 5 und die Umlenkrolle 16 für die Gegengewichte 9 vorgesehen ist. Die Umlenkrollen 15 und 16 sind mittels einer Befestigungskonsole 21 je an einer Führungsschiene 10 befestigt. 7 and 8 show a disposition as the last variant underlying drive. Here, the drive 12 with the Foundation support 13 is firmly connected and the supporting cables 3 are over Deflection rollers 15 and 16 on the head support 2 to the elevator car 5 and the counterweights 9 out, the pulley 15 for the Elevator car 5 and the deflection roller 16 for the counterweights 9 is provided. The deflection rollers 15 and 16 are by means of a Fastening bracket 21 each attached to a guide rail 10.

Der Fundamentträger 13 wird so zum Antrieb-Fundamentträger 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 Antriebe 12 vorgesehen werden und so einen Doppelantrieb-Fundamentträger 26 bilden.The foundation support 13 thus becomes the drive foundation support 25. A 1: 1 suspension is shown for the elevator car 5 and the Counterweights 9. However, it is also with the drive located below possible to implement a 2: 1 suspension. Likewise, a Doubling the drive power can be achieved by, as in overhead drive, two drives 12 are provided and so form a double drive foundation support 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.
Leistungsanpassungen bezüglich Tragkraft und Geschwindigkeit können durch Wahl der Anzahl der Antriebe 12, mit und ohne Reduktionsgetriebe, sowie kombiniert mit der Aufhängungsart 1:1 oder 2:1 vorgenommen werden. Bei Verwendung von mehreren Motoren 19 mit unterschiedlicher Leistung werden bezüglich Tragkraft und Geschwindigkeit noch grössere Anwendungsbereiche erschlossen.The examples shown show the options for adapting a modular system to a wide range of requirements in terms of conveyor load and speed. A large part of the same modules can be used for all disposition variants.
Performance adjustments with regard to load capacity and speed can be made by selecting the number of drives 12, with and without reduction gear, as well as combined with the suspension type 1: 1 or 2: 1. When using several motors 19 with different power, even larger areas of application are opened up in terms of load 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, a corresponding motor control for example with the same speed and torque setpoints, ensures that the same tensile forces on both sides to rule. As an inevitable synchronization of the two drives can with suitable means, for example with chain and Sprockets, mechanical coupling can also be provided.

Die schlanke Form des Antrieb-Kopfträgers 22 bzw. Antrieb-Fundamentträgers 25 macht es möglich, die Führungsschienen 10 mit sehr kurzen Befestigungen 11 ganz nahe an der Gebäudewand 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 form of the drive head support 22 or drive foundation support 25 makes it possible to use the guide rails 10 very short fastenings 11 very close to the building wall to arrange, then the horizontal forces occurring from the Building structure to be included. So that is the present Modular system also for the realization of backpack elevators suitable.
