Description

Die Erfindung betrifft eine Aufzuganlage mit einem Schacht, in dem ein erster Fahrkorb und ein unterhalb des ersten Fahrkorbes angeordneter zweiter Fahrkorb entlang einer gemeinsamen Fahrbahn getrennt voneinander in vertikaler Richtung nach oben und nach unten verfahrbar sind, wobei der erste Fahrkorb über erste Tragseile oder Tragriemen, die über eine oberhalb der beiden Fahrkörbe angeordnete erste Treibscheibe geführt sind, und über erste Unterseile oder Unterriemen, die über eine unterhalb der beiden Fahrkörbe angeordnete erste Umlenkrollenanordnung geführt sind, mit einem ersten Gegengewicht gekoppelt ist, und wobei der zweite Fahrkorb über zweite Tragseile oder Tragriemen, die über eine oberhalb der beiden Fahrkörbe angeordnete zweite Treibscheibe geführt sind, und über zweite Unterseile oder Unterriemen, die über eine unterhalb der beiden Fahrkörbe angeordnete zweite Umlenkrollenanordnung geführt sind, mit einem zweiten Gegengewicht gekoppelt ist.The invention relates to an elevator installation with a shaft in which a first car and a second car arranged below the first car can be moved vertically and vertically upwards and downwards along a common roadway, the first car being moved by first carrying cables or carrying belts, which are guided via a first traction sheave arranged above the two cars, and is coupled to a first counterweight via first sub-cables or sub-belts, which are guided via a first deflecting roller arrangement arranged below the two cars, and wherein the second car is connected via second carrying cables or carrying belts , Which are guided via a second traction sheave arranged above the two cars, and is coupled to a second counterweight via second lower ropes or lower belts, which are guided via a second deflecting roller arrangement arranged below the two cars.

Um innerhalb kurzer Zeit eine Vielzahl von Personen mittels einer Aufzuganlage zu befördern, ist es aus der internationalen Offenlegungsschrift WO 2004/048243 A1 bekannt, in einem Schacht zumindest zwei Fahrkörbe anzuordnen und getrennt voneinander vertikal nach oben und nach unten zu verfahren. Jedem Fahrkorb ist eine Antriebseinrichtung zugeordnet, mit deren Hilfe der Fahrkorb angetrieben werden kann. Jeder der beiden Fahrkörbe ist über Tragseile mit einem Gegengewicht gekoppelt, wobei die Tragseile jeweils über eine Treibscheibe geführt sind, mit deren Hilfe die Fahrkörbe verfahren werden können.In order to transport a large number of people by means of an elevator system within a short time, it is from the international publication WO 2004/048243 A1 known to arrange at least two cars in a shaft and to move separately vertically upwards and downwards. Each car is assigned a drive device with the aid of which the car can be driven. Each of the two cars is coupled via suspension cables with a counterweight, the suspension cables are each guided over a traction sheave, with the help of which the cars can be moved.

Derartige Aufzuganlagen kommen insbesondere in sehr hohen Gebäuden zum Einsatz. Hierbei kann das Eigengewicht der Tragseile oder Tragriemen dazu führen, dass bei einer Anordnung eines Fahrkorbes an einem Ende des Schachtes und der Anordnung des zugeordneten Gegengewichtes am anderen Ende des Schachtes die Tragseile bzw. Tragriemen aufgrund ihres Eigengewichtes über die Treibscheibe rutschen. Um das Gewicht der Tragseile oder Tragriemen auszugleichen, sind deshalb Unterseile oder Unterriemen bekannt, die jeweils einen Fahrkorb mit dem zugeordneten Gegengewicht koppeln, wobei sie über eine unterhalb der Fahrkörbe angeordnete Umlenkrollenanordnung herumgeführt sind und sich somit zumindest über einen Großteil ihrer Länge unterhalb des Fahrkorbes und des Gegengewichtes erstrecken.Such elevator systems are used in particular in very tall buildings. Here, the weight of the support cables or straps can cause that in an arrangement of a car at one end of the shaft and the arrangement of the associated counterweight at the other end of the shaft, the supporting cables or straps due to their own weight slip over the traction sheave. To compensate for the weight of the support ropes or straps, therefore, sub-ropes or bottom belts are known, each coupling a car with the associated counterweight, where they are guided around a arranged below the car Umlenkrollenanordnung and thus at least over much of their length below the car and extend the counterweight.

In der WO 2009/080538 A1 ist eine Aufzuganlage der eingangs genannten Art beschrieben, bei der die ersten Unterseile mit einem ersten Seilende am Schachtboden und mit einem zweiten Seilende an einem Beschwerungskörper oder ebenfalls am Schachtboden festgelegt sind. Dies erfordert eine aufwändige Seilführung der ersten Unterseile. In der WO 2009/153353 A1 ist eine Aufzuganlage der genannten Art beschrieben, die alle Mermkale des Oberbegriffs des Anspruchs 1 aufweist.In the WO 2009/080538 A1 an elevator system of the type mentioned is described in which the first sub-cables are fixed with a first end of the rope at the bottom of the shaft and with a second end of the rope to a weighting body or also at the bottom of the shaft. This requires a complicated cable guide the first sub-cables. In the WO 2009/153353 A1 an elevator system of the type mentioned is described, which has all Mermkale of the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine Aufzugsanlage der eingangs genannten Art derart weiterzubilden, dass sie eine einfachere Seil- oder Riemenführung der ersten Unterseile oder Unterriemen aufweist.
Diese Aufgabe wird bei einer Aufzuganlage der gattungsgemäßen Art erfindungsgemäß dadurch gelöst, dass die ersten Unterseile oder Unterriemen ein erstes und ein zweites Seil- oder Riemenende aufweisen, wobei sie mit beiden Seil- oder Riemenenden entweder am ersten Gegengewicht oder an der Unterseite des ersten Fahrkorbs festgelegt sind und um mindestens eine an der Unterseite des ersten Fahrkorbs beziehungsweise um mindestens eine am ersten Gegengewicht angeordnete Rolle herumgeführt sind.
Bei der erfindungsgemäßen Aufzuganlage sind die dem ersten Fahrkorb zugeordneten Unterseile oder Unterriemen mit ihren beiden Seil- oder Riemenenden entweder am ersten Gegengewicht oder an der Unterseite des ersten Fahrkorbs festgelegt. Ausgehend von einem ersten Seil- oder Riemenende erstrecken sich die ersten Unterseile oder Unterriemen über die erste Umlenkrollenanordnung und die mindestens eine Rolle. Um die mindestens eine Rolle sind die ersten Unterseile oder Unterriemen herumgeführt, und ausgehend von der mindestens einen Rolle laufen die ersten Unterseile oder Unterriemen zurück zur ersten Umlenkrollenanordnung und erstrecken sich von der ersten Umlenkrollenanordnung bis zum zweiten Seil- oder Riemenende. Die beiden Seil- oder Riemenenden können beispielsweise am ersten Gegengewicht festgelegt sein. Bei einer derartigen Ausgestaltung ist an der Unterseite des ersten Fahrkorbs die mindestens eine Rolle drehbar gelagert. Alternativ kann vorgesehen sein, dass die beiden Seil- oder Riemenenden der ersten Unterseile oder Unterriemen an der Unterseite des ersten Fahrkorbs festgelegt sind. Bei einer derartigen Ausgestaltung ist am ersten Gegengewicht mindestens eine Rolle drehbar gelagert. In beiden Fällen ermöglicht die gemeinsame Festlegung der beiden Seil- oder Riemenenden am ersten Gegengewicht oder an der Unterseite des ersten Fahrkorbs und das Herumführen der ersten Unterseile oder Unterriemen um mindestens eine Rolle, die an der Unterseite des ersten Fahrkorbs beziehungsweise am ersten Gegengewicht drehbar gelagert ist, eine konstruktiv einfache Seilführung für die ersten Unterseile oder Unterriemen. Dies ermöglicht es, die Kosten für die Aufzuganlage zu verringern.Object of the present invention is therefore to develop an elevator system of the type mentioned in such a way that it has a simpler cable or belt guide of the first sub-cables or lower belt.

In the elevator installation according to the invention, the sub-ropes or sub-belts assigned to the first car are fixed with their two cable or belt ends either on the first counterweight or on the underside of the first car. Starting from a first end of the cable or belt, the first lower cables or lower belts extend over the first deflecting roller arrangement and the at least one roller. The first sub-ropes or lower belts are guided around the at least one roller, and starting from the at least one roller, the first lower ropes or lower belts run back to the first deflecting roller assembly and extending from the first deflecting roller assembly to the second cable or belt end. The two cable or belt ends can be fixed, for example, on the first counterweight. In such an embodiment, the at least one roller is rotatably mounted on the underside of the first car. Alternatively it can be provided that the two cable or belt ends of the first sub-cables or sub-belts are fixed to the underside of the first car. In such an embodiment, at least one roller is rotatably mounted on the first counterweight. In both cases, the common fixing of the two cable or belt ends on the first counterweight or on the underside of the first car and the driving around the first sub-cables or sub-belts around at least one roller, which is rotatably mounted on the underside of the first car or on the first counterweight , a structurally simple cable guide for the first sub-cables or sub-belts. This makes it possible to reduce the cost of the elevator installation.

Die erfindungsgemäße Aufzuganlage hat darüber hinaus den Vorteil, dass die Seilführung der ersten Unterseile oder Unterriemen sehr platzsparend ausgeführt werden kann.The elevator system according to the invention also has the advantage that the cable guide of the first sub-cables or bottom belt can be made very compact.

Darüber hinaus ermöglicht es die Festlegung oder Umlenkung der ersten Unterseile oder Unterriemen an der Unterseite des ersten Fahrkorbs, einzelne Seitenbereiche des ersten Fahrkorbs freizuhalten von jeglichen Seilen und Riemen.In addition, the immobilization or redirection of the first sub-ropes or sub-belts on the underside of the first car makes it possible to keep individual side portions of the first car free of any ropes and straps.

Von Vorteil ist es, wenn die ersten Unterseile oder Unterriemen zwei Seil- oder Riemenabschnitte aufweisen, zwischen denen der zweite Fahrkorb angeordnet ist. Wie bereits erwähnt, ist der zweite Fahrkorb unterhalb des ersten Fahrkorbs positioniert, und durch die Anordnung des zweiten Fahrkorbes zwischen den beiden Seil- oder Riemenabschnitten der ersten Unterseile oder Unterriemen können die Seil- oder Riemenabschnitte der ersten Unterseile oder Unterriemen an zwei verschiedenen Seiten des zweiten Fahrkorbes verlaufen. Der zweite Fahrkorb wird somit durch die ersten Unterseile oder Unterriemen nicht beeinträchtigt und die Seilführung der ersten Unterseile oder Unterriemen erfordert nur einen geringen Aufwand. Insbesondere kann die Anzahl der für die Seilführung der ersten Unterseile oder Unterriemen zum Einsatz kommenden Umlenkrollen geringgehalten werden.It is advantageous if the first sub-cables or sub-belts have two cable or belt sections, between which the second car is arranged. As already mentioned, the second car is positioned below the first car, and by the arrangement of the second car between the two cable or belt sections of the first sub-cables or sub-belts, the cable or belt sections of the first sub-cables or sub-belts can be on two different sides of the second Car is lost. The second car is thus not by the first sub-ropes or sub-belt impaired and the rope guide the first sub-ropes or sub-belt requires only a small effort. In particular, the number of pulleys used for the cable guide of the first lower ropes or lower belts can be kept low.

Besonders günstig ist es, wenn die beiden Seil- oder Riemenabschnitte der ersten Unterseile oder Unterriemen an einander gegenüberliegenden Seiten des zweiten Fahrkorbes angeordnet sind. Insbesondere kann vorgesehen sein, dass die beiden Seil- oder Riemenabschnitte punktsymmetrisch zu einer Mittelachse des zweiten Fahrkorbes angeordnet sind.It is particularly advantageous if the two cable or belt sections of the first sub-cables or sub-belts are arranged on opposite sides of the second vehicle. In particular, it can be provided that the two cable or belt sections are arranged point-symmetrical to a central axis of the second car.

Eine besonders einfache Seilführung der ersten Unterseile oder Unterriemen wird bei einer vorteilhaften Ausgestaltung der Erfindung dadurch erzielt, dass sich die beiden Seil- oder Riemenabschnitte der ersten Unterseile oder Unterriemen außerhalb der vertikalen Projektionsfläche des ersten Fahrkorbes in vertikaler Richtung vom ersten Fahrkorb bis zur ersten Umlenkrollenanordnung erstrecken. Die Positionierung der beiden Seil- oder Riemenabschnitte außerhalb der vertikalen Projektionsfläche des ersten Fahrkorbes stellt auf konstruktiv einfache Weise sicher, dass der unterhalb des ersten Fahrkorbes angeordnete zweite Fahrkorb von den beiden Seil- oder Riemenabschnitten nicht beeinträchtigt wird. Der vertikale Verlauf der beiden Seil- oder Riemenabschnitte im Bereich zwischen dem ersten Fahrkorb und der ersten Umlenkrollenanordnung vereinfacht die Seilführung der ersten Unterseile oder Unterriemen, wobei zusätzliche Umlenkrollen in diesem Bereich entfallen können.A particularly simple cable guide of the first sub-cables or lower belts is achieved in an advantageous embodiment of the invention, that extend the two cable or belt sections of the first sub-cables or sub-belts outside the vertical projection surface of the first car in the vertical direction from the first car to the first Umlenkrollenanordnung , The positioning of the two cable or belt sections outside the vertical projection surface of the first car ensures in a structurally simple way that the arranged below the first car second car is not affected by the two cable or belt sections. The vertical course of the two cable or belt sections in the region between the first car and the first deflection roller arrangement simplifies the cable guidance of the first sub-cables or sub-belts, wherein additional deflection rollers can be dispensed with in this area.

Eine besonders platzsparende Anordnung der ersten Unterseile oder Unterriemen wird bei einer bevorzugten Ausgestaltung dadurch erzielt, dass sich die ersten Unterseile oder Unterriemen innerhalb der vertikalen Projektionsfläche des ersten Gegengewichts in vertikaler Richtung vom ersten Gegengewicht bis zur ersten Umlenkrollenanordnung erstrecken. Der vertikale Verlauf der ersten Unterseile oder Unterriemen im Bereich zwischen dem ersten Gegengewicht und der ersten Umlenkrollenanordnung hat darüber hinaus den Vorteil, dass zusätzliche Umlenkrollen in diesem Bereich entfallen können.A particularly space-saving arrangement of the first sub-cables or sub-belts is achieved in a preferred embodiment in that extend the first sub-cables or sub-belts within the vertical projection surface of the first counterweight in the vertical direction from the first counterweight to the first Umlenkrollenanordnung. The vertical course of the first lower ropes or lower belts in the region between the first counterweight and the first deflecting roller arrangement has the additional advantage that additional deflection rollers can be dispensed with in this area.

Bevorzugt ist die mindestens eine Rolle, um die die ersten Unterseile oder Unterriemen herumgeführt sind, unterhalb des ersten Gegengewichts angeordnet.Preferably, the at least one roller, around which the first lower ropes or lower belts are guided, is arranged below the first counterweight.

Von Vorteil ist es, wenn die Seil- oder Riemenenden der ersten Unterseile oder Unterriemen an ersten Befestigungsgliedern festgelegt sind, die an einander gegenüberliegenden Seiten des ersten Fahrkorbes vom ersten Fahrkorb seitlich nach außen abstehen. Ausgehend von den ersten Befestigungsgliedern können die ersten Unterseile oder Unterriemen an dem unterhalb des ersten Fahrkorbes angeordneten zweiten Fahrkorb vorbeigeführt werden. Hierbei können sie sich von den ersten Befestigungsgliedern in vertikaler Richtung nach unten zur ersten Umlenkrollenanordnung erstrecken.It is advantageous if the cable or belt ends of the first sub-cables or sub-belts are fixed to first fastening members, which protrude laterally outwardly on opposite sides of the first car from the first car. Starting from the first attachment members, the first sub-cables or sub-belts can be guided past the second car arranged below the first vehicle. Here they can extend from the first attachment members in the vertical direction down to the first deflection roller assembly.

Die Festlegung der ersten Unterseile oder Unterriemen an Befestigungsgliedern, die am ersten Fahrkorb positioniert sind, ermöglicht es, den ersten Fahrkorb in eher geringem Abstand zum zweiten Fahrkorb zu positionieren.The determination of the first sub-cables or sub-belts on fastening members, which are positioned on the first car, makes it possible to position the first car at a relatively small distance from the second car.

Die erste Umlenkrollenanordnung ist günstigerweise in einer Schachtgrube des Schachts angeordnet.The first deflection roller arrangement is conveniently arranged in a shaft pit of the shaft.

Die erste Umlenkrollenanordnung kann mindestens eine Umlenkrolle aufweisen, die in vertikaler Richtung verstellbar oder unverstellbar in der Schachtgrube gehalten ist.The first deflection roller assembly may comprise at least one deflection roller, which is held in the vertical direction adjustable or immovable in the pit.

Bei einer vorteilhaften Ausgestaltung der Erfindung weist die erste Umlenkrollenanordnung mehrere Umlenkrollen auf, wobei sämtliche Umlenkrollen an Begrenzungen des Schachts drehbar gelagert sind. Die Umlenkrollen können beispielsweise an Schachtwänden oder auch an einem Schachtboden des Schachts drehbar gelagert sein.In an advantageous embodiment of the invention, the first deflection roller assembly on a plurality of deflection rollers, wherein all the deflection rollers are rotatably mounted on boundaries of the shaft. The pulleys may be rotatably mounted, for example, on shaft walls or on a shaft bottom of the shaft.

Zur Festlegung der dem zweiten Fahrkorb zugeordneten zweiten Unterseile oder Unterriemen wurden bisher keine näheren Angaben gemacht. Bei einer vorteilhaften Ausführungsform sind die zweiten Unterseile oder Unterriemen mit einem ersten Seil- oder Riemenende am zweiten Fahrkorb und mit einem zweiten Seil- oder Riemenende am zweiten Gegengewicht festgelegt.To define the second car associated with the second sub-ropes or sub-belts have been made no further details. At a Advantageous embodiment, the second sub-cables or sub-belts are fixed with a first end of the cable or belt on the second car and with a second cable or belt end on the second counterweight.

Die ersten Tragseile oder Tragriemen sind bei einer bevorzugten Ausführungsform der Erfindung mit einem ersten Seil- oder Riemenende am ersten Fahrkorb und mit einem zweiten Seil- oder Riemenende am ersten Gegengewicht festgelegt. Alternativ kann vorgesehen sein, dass die ersten Tragseile oder Tragriemen um eine am ersten Fahrkorb und/oder am ersten Gegengewicht gehaltene Rolle herumgeführt sind.The first support cables or straps are fixed in a preferred embodiment of the invention with a first cable or belt end on the first car and with a second cable or belt end on the first counterweight. Alternatively, it can be provided that the first carrying cables or carrying belts are guided around a roller held on the first car and / or on the first counterweight.

Die zweiten Tragseile oder Tragriemen sind günstigerweise am zweiten Fahrkorb und am zweiten Gegengewicht festgelegt. Alternativ kann vorgesehen sein, dass die zweiten Tragseile oder Tragriemen um mindestens eine am zweiten Fahrkorb und/oder am zweiten Gegengewicht gehaltene Rolle herumgeführt sind.The second support cables or straps are conveniently fixed to the second car and the second counterweight. Alternatively, it can be provided that the second carrying cables or carrying belts are guided around at least one roller held on the second car and / or on the second counterweight.

Besonders vorteilhaft ist es, wenn die zweiten Tragseile oder Tragriemen zwei Tragseil- oder Tragriemenstränge ausbilden, zwischen denen der erste Fahrkorb angeordnet ist. Ausgehend vom zweiten Fahrkorb können sich die beiden Tragseil- oder Tragriemenstränge entlang verschiedener Seiten des ersten Fahrkorbes erstrecken, der oberhalb des zweiten Fahrkorbes positioniert ist.It is particularly advantageous if the second carrying cables or carrying straps form two carrying cable or carrying belt strands, between which the first freight car is arranged. Starting from the second car, the two crawler or support belt strands may extend along different sides of the first car, which is positioned above the second car.

Insbesondere kann vorgesehen sein, dass die beiden Tragseil- oder Tragriemenstränge der zweiten Tragseile oder Tragriemen punktsymmetrisch zu einer Mittelachse des ersten Fahrkorbes angeordnet sind.In particular, it can be provided that the two support cable or support belt strands of the second support cables or support belts are arranged point-symmetrical to a central axis of the first car.

Bei einer vorteilhaften Ausgestaltung der Erfindung sind am zweiten Fahrkorb zweite Befestigungsglieder angeordnet, die an einander gegenüberliegenden Seiten des zweiten Fahrkorbs vom zweiten Fahrkorb seitlich nach außen abstehen, wobei die beiden Tragseil- oder Tragriemenstränge des zweiten Tragseils oder Tragriemens mit Hilfe der zweiten Befestigungsglieder am zweiten Fahrkorb festgelegt sind.In an advantageous embodiment of the invention, second fastening members are arranged on the second car, which project laterally outwardly on opposite sides of the second car from the second car, wherein the two support cable or support belt strands of the second support cable or support belt using the second attachment members on the second car are fixed.

Eine besonders platzsparende Führung sowohl der Tragseile oder Tragriemen als auch der Unterseile oder Unterriemen der beiden Fahrkörbe wird bei einer vorteilhaften Ausführungsform der Erfindung dadurch erzielt, dass die ersten Unterseile oder Unterriemen mit Hilfe eines Paares von ersten Befestigungsgliedern oder ersten Rollen an der Unterseite des ersten Fahrkorbs gehalten sind und die Tragseile oder Tragriemen des zweiten Fahrkorbes mit Hilfe eines Paares von zweiten Befestigungsgliedern am zweiten Fahrkorb - vorzugsweise an dessen Oberseite - festgelegt sind, wobei eine gedachte Verbindungslinie der ersten Befestigungsglieder beziehungsweise der ersten Rollen in einer vertikalen Projektion eine gedachte Verbindungslinie der zweiten Befestigungsglieder kreuzt. Bezogen auf eine gemeinsame Mittelachse der beiden Fahrkörbe weist somit die gedachte Verbindungslinie der ersten Befestigungsglieder beziehungsweise der ersten Rollen eine andere Winkelstellung als die gedachte Verbindungslinie der zweiten Befestigungsglieder auf. Die gedachten Verbindungslinien können hierbei senkrecht zueinander ausgerichtet sein. Von besonderem Vorteil ist es jedoch, wenn die gedachten Verbindungslinien einander X-förmig überkreuzen, wobei der Kreuzungswinkel zwischen den beiden gedachten Verbindungslinien kleiner als 90° ist. Beispielsweise kann der Kreuzungswinkel 20 bis 70° betragen. Es hat sich gezeigt, dass dadurch eine besonders platzsparende Anordnung der ersten Unterseile oder Unterriemen und der zweiten Tragseile oder Tragriemen ermöglicht wird.A particularly space-saving guidance of both the carrying ropes or carrying strap and the lower ropes or lower belt of the two cars is achieved in an advantageous embodiment of the invention in that the first sub-cables or sub-belts using a pair of first attachment members or first rollers on the underside of the first car are held and the support cables or straps of the second car using a pair of second attachment members on the second car - preferably at the top - are fixed, wherein an imaginary line connecting the first attachment members or the first rollers in a vertical projection an imaginary line connecting the second attachment members crosses. Based on a common central axis of the two cars, the imaginary connecting line of the first fastening members or of the first rollers thus has a different angular position than the imaginary connecting line of the second fastening members. The imaginary connecting lines can in this case be aligned perpendicular to one another. However, it is particularly advantageous if the imaginary connecting lines cross over each other in an X-shaped manner, wherein the crossing angle between the two imaginary connecting lines is less than 90 °. For example, the crossing angle can be 20 to 70 °. It has been found that this allows a particularly space-saving arrangement of the first sub-ropes or sub-belts and the second supporting ropes or carrying strap.

FIG. 2:
a schematic representation of a second advantageous embodiment of an elevator system according to the invention.

In Figur 1 ist schematisch eine erste vorteilhafte Ausführungsform einer erfindungsgemäßen Aufzuganlage dargestellt, die insgesamt mit dem Bezugszeichen 10 belegt ist. Die Aufzuganlage 10 umfasst einen Schacht 12, der sich von einer Schachtdecke 14 bis zu einem Schachtboden 16 erstreckt und mehrere Schachtwände aufweist, wobei in Figur 1 lediglich eine erste Schachtwand 18 und eine zweite Schachtwand 20 erkennbar sind.In FIG. 1 schematically a first advantageous embodiment of an elevator system according to the invention is shown, which is generally occupied by the reference numeral 10. The elevator installation 10 comprises a shaft 12 which extends from a shaft ceiling 14 to a shaft floor 16 and has a plurality of shaft walls, wherein FIG. 1 only a first shaft wall 18 and a second shaft wall 20 can be seen.

Die Aufzuganlage 10 wird nachfolgend der Einfachheit halber am Beispiel des Einsatzes von Tragseilen und Unterseilen erläutert. Es könnten jedoch statt der Tragseile und Unterseile auch Tragriemen und Unterriemen zum Einsatz kommen. Es versteht sich, dass sich die Erfindung in gleicher Weise auf Tragseile und Unterseile wie auch auf Tragriemen und Unterriemen erstreckt.The elevator installation 10 will be explained below for the sake of simplicity using the example of the use of suspension ropes and sub-cables. However, instead of the carrying ropes and sub-ropes, carrying straps and lower belts could also be used. It is understood that the invention extends in the same way on suspension ropes and sub-cables as well as on shoulder straps and bottom straps.

Im Schacht 12 sind ein erster Fahrkorb 22 und ein zweiter Fahrkorb 24 entlang an sich bekannter und deshalb zur Erzielung einer besseren Übersicht in der Zeichnung nicht dargestellter gemeinsamer Führungsschienen nach oben und nach unten verfahrbar. Der erste Fahrkorb 22 ist oberhalb des zweiten Fahrkorbes 24 angeordnet und über erste Tragseile 26 mit einem ersten Gegengewicht 28 gekoppelt. Die ersten Tragseile 26 sind über eine erste motorisch drehbare Treibscheibe 30 geführt, mit deren Hilfe der erste Fahrkorb 22 in üblicher Weise vertikal nach oben und vertikal nach unten verfahren werden kann.In the shaft 12 are a first car 22 and a second car 24 along per se known and therefore not shown to achieve a better overview in the drawing common guide rails movable up and down. The first car 22 is arranged above the second car 24 and coupled via first support cables 26 with a first counterweight 28. The first support cables 26 are guided over a first motor-rotatable traction sheave 30, by means of which the first car 22 can be moved vertically upward and vertically downward in the usual way.

Die ersten Tragseile 26 sind mit einem ersten Tragseilende 32 zentrisch an einer Fahrkorbdecke 34 des ersten Fahrkorbes 22 festgelegt, und mit einem zweiten Tragseilende 36 sind die ersten Tragseile 26 zentrisch an einer Oberseite 38 des ersten Gegengewichtes 28 festgelegt.The first support cables 26 are fixed centrally to a car ceiling 34 of the first car 22 with a first support cable end 32, and with a second support cable end 36, the first support cables 26 are fixed centrally on an upper side 38 of the first counterweight 28.

Der zweite Fahrkorb 24 ist über zweite Tragseile 40 mit einem zweiten Gegengewicht 42 gekoppelt und über eine zweite Treibescheibe 44 geführt, mit deren Hilfe der zweite Fahrkorb 24 vertikal nach oben und nach unten verfahren werden kann.The second car 24 is coupled via second support cables 40 with a second counterweight 42 and guided over a second drive plate 44, by means of which the second car 24 can be moved vertically upwards and downwards.

Die zweiten Tragseile 40 bilden einen ersten Tragseilstrang 46 und einen zweiten Tragseilstrang 48 aus, die sich zwischen der zweiten Treibscheibe 44 und dem zweiten Fahrkorb 24 erstrecken, wobei der erste Fahrkorb 22 zwischen dem ersten Tragseilstrang 46 und dem zweiten Tragseilstrang 48 der zweiten Tragseile positioniert ist. Die beiden Tragseilstränge 46, 48 erstrecken sich auf einander gegenüberliegenden Seiten des ersten Fahrkorbes 22, wobei sie in Höhe des ersten Fahrkorbes 22 punktsymmetrisch zu einer gemeinsamen Mittelachse 50 der beiden Fahrkörbe 22, 24 angeordnet sind.The second catenaries 40 form a first catenary 46 and a second catenary 48 extending between the second pulley 44 and the second car 24, the first car 22 being positioned between the first catenary 46 and the second catenary 48 of the second catenaries , The two supporting cable strands 46, 48 extend on opposite sides of the first car 22, wherein they are in the amount of the first car 22 point symmetrical to a common center axis 50 of the two cars 22, 24 are arranged.

Der erste Tragseilstrang 46 erstreckt sich ausgehend von der zweiten Treibscheibe 44 vertikal nach unten bis zu einem ersten Befestigungsglied 52, das an einer Fahrkorbdecke 54 des zweiten Fahrkorbes 24 angeordnet und seitlich nach außen vom zweiten Fahrkorb 24 absteht.The first support cable strand 46 extends from the second traction sheave 44 vertically down to a first attachment member 52 which is disposed on a car ceiling 54 of the second car 24 and laterally projects outwardly from the second car 24.

Der zweite Tragseilstrang 48 ist ausgehend von der zweiten Treibscheibe 44 über eine erste Umlenkrolle 56 und eine zweite Umlenkrolle 58 zu einem an der Fahrkorbdecke 54 angeordneten zweiten Befestigungsglied 60 geführt, das auf der dem ersten Befestigungsglied 52 abgewandten Seite des zweiten Fahrkorbes 24 seitlich nach außen vom zweiten Fahrkorb 24 absteht. Die beiden Befestigungsglieder 52 und 60 sind punktsymmetrisch zur gemeinsamen Mittelachse der beiden Fahrkörbe 22, 24 angeordnet.The second support cable strand 48 is guided starting from the second traction sheave 44 via a first guide roller 56 and a second guide roller 58 to a arranged on the car ceiling 54 second attachment member 60 which on the side facing away from the first attachment member 52 side of the second car 24 laterally outwardly from second car 24 protrudes. The two fastening members 52 and 60 are arranged point-symmetrical to the common center axis of the two cars 22, 24.

Zum Ausgleich des Gewichtes der ersten Tragseile 26 weist die Aufzuganlage 10 erste Unterseile 62 auf, die den ersten Fahrkorb 22 auf der den ersten Tragseilen 26 abgewandten Seite mit dem ersten Gegengewicht 28 koppeln. Die ersten Unterseile 62 weisen ein erstes Seilende 64 auf, das über ein drittes Befestigungsglied 66 an einem Fahrkorbboden 68 des ersten Fahrkorbes 22 festgelegt ist, wobei das dritte Befestigungsglied 66 vom ersten Fahrkorb 22 seitlich nach außen absteht.To compensate for the weight of the first support cables 26, the elevator installation 10 has first sub-cables 62 which couple the first car 22 to the first counterweight 28 on the side facing away from the first support cables 26. The first sub-cables 62 have a first cable end 64, which is fixed via a third attachment member 66 to a car floor 68 of the first car 22, wherein the third attachment member 66 projects laterally outward from the first car 22.

Ausgehend vom dritten Befestigungsglied 66 verläuft ein erster Seilabschnitt 70 der ersten Unterseile 62 vertikal nach unten bis zu einer ersten Umlenkrollenanordnung 72, die im Bereich einer Schachtgrube 74 des Schachtes 12 dem Schachtboden 16 benachbart angeordnet ist. Die erste Umlenkrollenanordnung 72 umfasst eine dritte Umlenkrolle 76 und eine vierte Umlenkrolle 78, die über in der Zeichnung nicht dargestellte, dem Fachmann an sich bekannte Lagermittel am Schachtboden 16 oder an Schachtwänden frei drehbar gelagert sind. Darüber hinaus weist die erste Umlenkrollenanordnung 72 eine fünfte Umlenkrolle 80 auf, die ebenfalls mittels in der Zeichnung nicht dargestellter Lagerelemente am Schachtboden 16 oder an Schachtwänden frei drehbar gelagert ist.Starting from the third attachment member 66, a first cable section 70 of the first sub-cables 62 runs vertically down to a first deflection roller assembly 72 which in the region of a pit 74 of the shaft 12 the Well bottom 16 is disposed adjacent. The first deflecting roller arrangement 72 comprises a third deflecting roller 76 and a fourth deflecting roller 78 which are freely rotatably mounted on the shaft bottom 16 or on shaft walls via bearing means (not shown in the drawing) known to those skilled in the art. In addition, the first deflecting roller arrangement 72 has a fifth deflecting roller 80, which is likewise freely rotatably mounted on the shaft bottom 16 or on shaft walls by means of bearing elements not shown in the drawing.

Der erste Seilabschnitt 70 ist um die dritte Umlenkrolle 76 und die vierte Umlenkrolle 78 herumgeführt. Ausgehend von der vierten Umlenkrolle 78 erstreckt sich der erste Seilabschnitt 70 in vertikaler Richtung nach oben zu einer Rolle 82, die an einer Unterseite 84 des ersten Gegengewichtes 28 frei drehbar gelagert ist. Von der Rolle 82 erstreckt sich ein zweiter Seilabschnitt 86 der ersten Unterseile 62 vertikal nach unten bis zur fünften Umlenkrolle 80. Der zweite Seilabschnitt 86 ist um die fünfte Umlenkrolle 80 herumgeführt und erstreckt sich ausgehend von der fünften Umlenkrolle 80 in vertikaler Richtung nach oben bis zu einem vierten Befestigungsglied 88, mit dessen Hilfe ein zweites Seilende 90 der ersten Unterseile 62 am ersten Fahrkorb 22 festgelegt ist. Das vierte Befestigungsglied 88 ist in Höhe des Fahrkorbbodens 68 des ersten Fahrkorbes 22 angeordnet und steht seitlich nach außen vom ersten Fahrkorb 22 ab. Das dritte Befestigungsglied 66 und das vierte Befestigungsglied 88 sind bezogen auf die gemeinsame Mittelachse 50 der beiden Fahrkörbe 22, 24 punktsymmetrisch zueinander angeordnet. Eine gedachte Verbindungslinie, die das dritte Befestigungsglied 66 mit dem vierten Befestigungsglied 88 verbindet, kreuzt hierbei in einer vertikalen Projektion eine gedachte Verbindungslinie, die das erste Befestigungsglied 52 mit dem zweiten Befestigungsglied 60 verbindet. In einer vertikalen Projektion sind die beiden Verbindungslinien X-förmig zueinander ausgerichtet, wobei der Kreuzungswinkel zwischen den beiden gedachten Verbindungslinien etwa 20° bis ca. 70°, insbesondere etwa 25° bis ca. 60° beträgt.The first cable section 70 is guided around the third guide roller 76 and the fourth guide roller 78. Starting from the fourth deflection roller 78, the first cable section 70 extends in a vertical direction upwards to a roller 82, which is freely rotatably mounted on an underside 84 of the first counterweight 28. From the roller 82, a second cable section 86 of the first sub-cables 62 extends vertically down to the fifth guide roller 80. The second cable section 86 is guided around the fifth guide roller 80 and extends from the fifth guide roller 80 in the vertical direction up to a fourth attachment member 88, by means of which a second cable end 90 of the first sub-ropes 62 is fixed to the first car 22. The fourth attachment member 88 is disposed at the level of the car floor 68 of the first car 22 and is laterally outwardly from the first car 22 from. The third fastening member 66 and the fourth fastening member 88 are arranged with respect to the common center axis 50 of the two cars 22, 24 point-symmetrical to each other. An imaginary connecting line, which connects the third attachment member 66 with the fourth attachment member 88, crosses here in a vertical projection an imaginary connection line connecting the first attachment member 52 with the second attachment member 60. In a vertical projection, the two connecting lines are X-shaped aligned with each other, wherein the crossing angle between the two imaginary connecting lines about 20 ° to about 70 °, in particular about 25 ° to about 60 °.

Wie bereits erwähnt, wird mit Hilfe der ersten Unterseile 62 das Gewicht der ersten Tragseile 26 ausgeglichen. Dies stellt sicher, dass die ersten Tragseile 26 nicht über die erste Treibscheibe 30 rutschen können.As already mentioned, the weight of the first suspension cables 26 is compensated with the aid of the first sub-cables 62. This ensures that the first support cables 26 can not slip over the first traction sheave 30.

Um das Gewicht der zweiten Tragseile 40 ausgleichen zu können, weist die Aufzuganlage 10 zweite Unterseile 92 auf, die auf der den zweiten Tragseilen 40 abgewandten Seite des zweiten Fahrkorbes 24 den zweiten Fahrkorb 24 mit dem zweiten Gegengewicht 42 koppeln. Ein erstes Seilende 94 ist zentrisch an einem Fahrkorbboden 96 des zweiten Fahrkorbes 24 festgelegt. Ausgehend vom ersten Seilende 94 erstrecken sich die zweiten Unterseile 92 in vertikaler Richtung nach unten zu einer zweiten Umlenkrollenanordnung 98, die im Bereich der Schachtgrube 74 angeordnet ist und eine sechste Umlenkrolle 100 sowie eine siebte Umlenkrolle 102 aufweist. Ausgehend vom ersten Seilende 94 sind die zweiten Unterseile 92 um die sechste Umlenkrolle 100 und die siebte Umlenkrolle 102 herumgeführt. Von der siebten Umlenkrolle 102 erstrecken sich die zweiten Unterseile 92 in vertikaler Richtung nach oben, wobei sie mit einem zweiten Seilende 104 an einer Unterseite 106 des zweiten Gegengewichts 42 festgelegt sind.In order to compensate for the weight of the second support cables 40, the elevator installation 10 has second sub-cables 92 which couple the second car 24 with the second counterweight 42 on the side of the second car 24 remote from the second support cables 40. A first cable end 94 is fixed centrally on a car floor 96 of the second car 24. Starting from the first cable end 94, the second lower cables 92 extend in a vertical direction down to a second deflection roller assembly 98, which is arranged in the region of the shaft pit 74 and has a sixth deflection roller 100 and a seventh deflection roller 102. Starting from the first end of the rope 94, the second sub-ropes 92 are guided around the sixth deflection roller 100 and the seventh deflection roller 102. From the seventh guide pulley 102, the second sub-ropes 92 extend upward in the vertical direction, being fixed to a lower end 106 of the second counterweight 42 with a second cable end 104.

Die beiden Fahrkörbe 22, 24 können in sehr geringem Abstand zueinander positioniert werden und durch die X-förmige Anordnung der gedachten Verbindungslinien, die die Befestigungsglieder 52 und 60 beziehungsweise die Befestigungsglieder 66 und 88 miteinander verbinden, ist eine gegenseitige Behinderung der Tragseilstränge 46, 48 der zweiten Tragseile 40 durch die Seilabschnitte 70, 86 der ersten Unterseile 62 ausgeschlossen.The two cars 22, 24 can be positioned at a very small distance from each other and by the X-shaped arrangement of the imaginary connecting lines that connect the fasteners 52 and 60 and the fasteners 66 and 88 together, is a mutual obstruction of the support cable strands 46, 48 of second support cables 40 through the cable sections 70, 86 of the first sub-cables 62 excluded.

In Figur 2 ist schematisch eine zweite vorteilhafte Ausführungsform einer erfindungsgemäßen Aufzuganlage dargestellt, die insgesamt mit dem Bezugszeichen 120 belegt ist. Die Aufzuganlage 120 ist weitgehend identisch ausgebildet wie die voranstehende, unter Bezugnahme auf Figur 1 erläuterte Aufzuganlage 10. Für identische Bauteile werden daher in Figur 2 dieselben Bezugszeichen verwendet wie in Figur 1 und bezüglich dieser Bauteile wird zur Vermeidung von Wiederholungen auf die voranstehenden Erläuterungen Bezug genommen.In FIG. 2 schematically a second advantageous embodiment of an elevator system according to the invention is shown, which is occupied by the reference numeral 120 in total. The elevator installation 120 is largely identical to the one described above, with reference to FIG FIG. 1 explained elevator system 10. For identical components are therefore in FIG. 2 the same reference numerals as in FIG. 1 and regarding these components is to avoid from repetitions to the above explanations.

Bei der voranstehend erläuterten Aufzuganlage 10 sind das erste Seilende 64 und das zweite Seilende 90 der ersten Unterseile 62 am ersten Fahrkorb 22 festgelegt und die ersten Unterseile 62 sind um die am ersten Gegengewicht 28 drehbar gelagerte erste Rolle 82 herumgeführt. Im Gegensatz hierzu kommen bei der in Figur 2 dargestellten Aufzuganlage 120 erste Unterseile 122 zum Einsatz, die mit einem ersten Seilende 124 und einem zweiten Seilende 126 an der Unterseite 84 des ersten Gegengewichtes 28 festgelegt sind. Unterhalb des Fahrkorbbodens 68 sind die ersten Unterseile 122 bei der Aufzuganlage 120 um eine zweite Rolle 128 und eine dritte Rolle 130 herumgeführt. Ausgehend vom ersten Seilende 124 erstrecken sich die ersten Unterseile 122 innerhalb der vertikalen Projektion des ersten Gegengewichtes 28 vertikal nach unten bis zur fünften Umlenkrolle 80, um die sie herumgeführt sind. Ausgehend von der fünften Umlenkrolle 80 verlaufen die ersten Unterseile 122 in vertikaler Richtung nach oben bis zur dritten Rolle 130, wobei sie an einer Seite des zweiten Fahrkorbes 24 vorbeigeführt sind. Ausgehend von der dritten Rolle 130 verlaufen die ersten Unterseile 122 in horizontaler Richtung unterhalb des Fahrkorbbodens 28 des ersten Fahrkorbes 22 bis zur zweiten Rolle 128, von der aus sich die ersten Unterseile 122 in vertikaler Richtung nach unten bis zur dritten Umlenkrolle 76 erstrecken. Von der dritten Umlenkrolle 76 verlaufen die ersten Unterseile 122 in horizontaler Richtung zur vierten Umlenkrolle 78, von der aus sich die ersten Unterseile 122 bis zu dem an der Unterseite 84 des ersten Gegengewichtes 28 festgelegten zweiten Seilende 126 erstrecken.In the elevator system 10 explained above, the first cable end 64 and the second cable end 90 of the first sub-cables 62 are fixed to the first car 22 and the first sub-cables 62 are guided around the first roller 82 rotatably mounted on the first counterweight 28. In contrast, at the in FIG. 2 illustrated elevator system 120 first sub-cables 122 are used, which are fixed with a first end of the rope 124 and a second end of the rope 126 on the bottom 84 of the first counterweight 28. Underneath the car floor 68, the first sub-cables 122 in the elevator installation 120 are guided around a second roller 128 and a third roller 130. Starting from the first cable end 124, the first sub-cables 122 extend vertically downwards within the vertical projection of the first counterweight 28 to the fifth guide roller 80 around which they are guided. Starting from the fifth guide roller 80, the first sub-cables 122 extend in the vertical direction up to the third roller 130, wherein they are guided past on one side of the second car 24. Starting from the third roller 130, the first sub-cables 122 extend in a horizontal direction below the car floor 28 of the first car 22 to the second roller 128, from which the first sub-cables 122 extend in a vertical direction down to the third guide roller 76. From the third deflection roller 76, the first sub-cables 122 extend in a horizontal direction to the fourth deflection roller 78, from which the first sub-cables 122 extend to the second cable end 126 defined on the underside 84 of the first counterweight 28.

Bei der Aufzuganlage 120 kreuzt die gedachte Verbindungslinie, die das erste Befestigungsglied 52 mit dem zweiten Befestigungsglied 60 verbindet, in einer vertikalen Projektion die gedachte Verbindungslinie, die die zweite Rolle 128 mit der dritten Rolle 130 verbindet, wobei die beiden gedachten Verbindungslinien X-förmig zueinander ausgerichtet sind und einen Kreuzungswinkel im Bereich von etwa 20° bis ca. 70° aufweisen, insbesondere einen Kreuzungswinkel im Bereich von etwa 25° bis ca. 60°. Durch eine derartige Anordnung der ersten und zweiten Befestigungsglieder 52, 60 und der zweiten und dritten Rollen 128, 130 kann eine gegenseitige Behinderung der Tragseilstränge 46, 48 der zweiten Tragseile 40 durch die ersten Unterseile 122 ausgeschlossen werden und die zweiten Tragseile 40 sowie die ersten Unterseile 122 können sehr platzsparend angeordnet werden.In the elevator installation 120, the imaginary connection line connecting the first attachment member 52 to the second attachment member 60 crosses in a vertical projection the imaginary connection line connecting the second roller 128 to the third roller 130, the two imaginary connection lines being X-shaped are aligned and have a crossing angle in the range of about 20 ° to about 70 °, in particular a crossing angle in the range of about 25 ° to about 60 °. By such an arrangement of the first and second fastening members 52, 60 and the second and third rollers 128, 130, a mutual obstruction of the support cords 46, 48 of the second support cables 40 by the first sub-cables 122 are excluded and the second support cables 40 and the first sub-cables 122 can be arranged very space-saving.

Sowohl bei der in Figur 1 schematisch dargestellten Aufzuganlage 10 als auch bei der in Figur 2 schematisch dargestellten Aufzuganlage 120 ist die Seilführung der ersten Unterseile 62 beziehungsweise 122 kostengünstig erzielbar und sämtliche Trag- und Unterseile können platzsparend im Schacht 12 angeordnet werden.Both at the in FIG. 1 schematically illustrated elevator system 10 and in the in FIG. 2 schematically illustrated elevator installation 120, the cable guide of the first sub-cables 62 and 122 can be achieved inexpensively and all support and sub-cables can be arranged to save space in the shaft 12.
