Description

Die Erfindung betrifft eine Aufzuganlage mit zumindest einem Aufzugkabinenträger, der zumindest zwei Aufzugkabinen aufnehmen kann. Speziell betrifft die Erfindung das Gebiet der Aufzuganlagen, die als sogenannte Doppeldecker-Aufzuganlagen ausgestaltet sind.The invention relates to an elevator installation with at least one elevator car carrier which can accommodate at least two elevator cars. Specifically, the invention relates to the field of elevator systems, which are designed as so-called biplane elevator systems.

Aus der JP 2007-331871 A ist ein Doppeldecker-Aufzug bekannt. Der bekannte Aufzug weist einen Kabinenrahmen auf, in dem zwei Aufzugkabinen vertikal übereinander angeordnet sind. Die beiden Aufzugkabinen stehen hierbei jeweils auf einem Träger mit Seilrollen. Ferner ist an dem Kabinenrahmen eine Antriebseinheit vorgesehen, um die ein Hubseil geführt ist. Das Hubseil ist einerseits um die Seilrollen des Trägers für die eine Aufzugkabine und andererseits um die Seilrollen des Trägers der anderen Aufzugkabine geführt. Durch Betätigen des Hubseils mittels der Antriebseinheit können die so aufgehängten Aufzugkabinen relativ zu dem Kabinenrahmen angehoben und abgesenkt werden. Hierdurch können die beiden Aufzugkabinen innerhalb des Kabinenrahmens unterschiedlich positioniert werden.From the JP 2007-331871 A is a double-decker elevator known. The known elevator has a car frame in which two elevator cars are arranged vertically one above the other. The two elevator cabins are each on a support with pulleys. Further, a drive unit is provided on the cabin frame, around which a hoisting rope is guided. The hoist rope is guided on the one hand around the pulleys of the carrier for the one elevator car and on the other hand around the pulleys of the carrier of the other elevator car. By operating the hoisting rope by means of the drive unit, the elevator cars suspended in this way can be raised and lowered relative to the car frame. As a result, the two elevator cars can be positioned differently within the cabin frame.

Der aus der JP 2007-331871 A bekannte Doppeldecker-Aufzug hat den Nachteil, dass die Antriebseinheit, die an dem Kabinenrahmen angeordnet ist, einen relativ großen Platzbedarf hat. Hierbei muss die Antriebseinheit eine ausreichende Leistungsfähigkeit aufweisen, da einerseits zu der einen Aufzugkabine und andererseits zu der anderen Aufzugkabine unterschiedliche Zugkräfte auf das Hubseil wirken können. Dies ist unter anderem durch eine unterschiedliche Beladung der Aufzugkabinen möglich. Außerdem wirken große Kräfte an einer Treibscheibe der Antriebseinheit, wenn beide Aufzugkabinen maximal beladen sind. Somit muss die Antriebseinheit eine große Leistungsfähigkeit aufweisen, um auch bei maximalen oder extrem unterschiedlichen Beladungen der Aufzugkabinen die auftretenden Kräfte und Momente aufzunehmen und die gewünschte Verstellbewegung durchzuführen.The from the JP 2007-331871 A known double-decker elevator has the disadvantage that the drive unit, which is arranged on the cabin frame, has a relatively large amount of space. In this case, the drive unit must have sufficient performance, on the one hand to the one elevator car and on the other hand to the other Elevator cab different pulling forces can act on the hoisting rope. This is possible, inter alia, by a different loading of the elevator cars. In addition, large forces act on a traction sheave of the drive unit when both elevator cars are loaded to the maximum. Thus, the drive unit must have a high capacity to absorb the forces and moments occurring even with maximum or extremely different loadings of the elevator cars and perform the desired adjustment.

Specifically, it is an object of the invention to provide an elevator system in which an adjustment of the arranged on the elevator car carrier elevator car is made possible in an optimized manner and in particular the requirements are reduced to the drive unit.

Somit ist eine Verstelleinrichtung 40 ausgebildet, die zum Verstellen der beiden Aufzugkabinen 10, 11 relativ zu dem Aufzugkabinenträger 2 und relativ zueinander dient. Die Verstelleinrichtung 40 umfasst die von der Antriebseinheit 14 antreibbare Antriebsrolle 15, die erste Rollenanordnung 16 mit der ersten Rolle 17 und der zweiten Rolle 18, die zweite Rollenanordnung 19 mit der ersten Rolle 20 und der zweiten Rolle 21 sowie das erste Zugmittel 22 und das zweite Zugmittel 23.Thus, an adjusting device 40 is formed, which serves for adjusting the two elevator cars 10, 11 relative to the elevator car carrier 2 and relative to each other. The adjusting device 40 comprises the drive roller 15 which can be driven by the drive unit 14, the first roller arrangement 16 with the first roller 17 and the second roller 18, the second roller arrangement 19 with the first roller 20 and the second roller 21, and the first traction means 22 and the second Traction means 23.

Die erste Aufzugkabine 10 weist ein Ausstiegsniveau 45 auf. Ferner weist die zweite Aufzugkabine 11 ein Ausstiegsniveau 46 auf. Die Ausstiegsniveaus 45, 46 weisen einen Abstand 47 voneinander auf. Der Abstand 47 zwischen den Aufzugkabinen 10, 11 kann über die Antriebseinheit 14 und die Verstelleinrichtung 40 variiert werden. In Abhängigkeit von der Drehrichtung der Antriebsrolle 15 wird hierbei der Abstand 47 innerhalb gewisser Grenzen vergrößert oder verkleinert. Beispielsweise kann innerhalb eines Gebäudes ein Stockwerksabstand variieren. Insbesondere kann ein Stockwerksabstand bezüglich einer Lobby größer als ein ansonsten vorgesehener Stockwerksabstand sein. Beispielsweise kann der Abstand 47 zwischen den Aufzugkabinen 10, 11 ausgehend von einem minimalen Abstand 47 um bis zu 3 m vergrößert werden.The first elevator car 10 has an exit level 45. Furthermore, the second elevator car 11 has an exit level 46. The exit levels 45, 46 have a distance 47 from each other. The distance 47 between the elevator cars 10, 11 can be varied via the drive unit 14 and the adjusting device 40. Depending on the direction of rotation of the drive roller 15 in this case the distance 47 is increased or decreased within certain limits. For example, a floor space may vary within a building. In particular, a floor distance with respect to a lobby may be greater than an otherwise provided floor space. For example, the distance 47 between the elevator cars 10, 11 can be increased from a minimum distance 47 by up to 3 m.

In dem in der Fig. 1 dargestellten Ausgangszustand befindet sich die Unterseite 29 der zweiten Aufzugkabine 11 im Bereich eines mittleren Querträgers 48 des Aufzugkabinenträgers 2. Ein weiteres Absenken der zweiten Aufzugkabine 11 relativ zu dem Aufzugkabinenträger 2 ist daher nicht möglich. Der gezeigte Abstand 47 gibt daher einen vorgegebenen minimalen Abstand 47 an. Hierbei kann der minimale Abstand 47 über die Länge der Zugmittel 22, 23 innerhalb gewisser Grenzen eingestellt werden.In the in the Fig. 1 illustrated initial state is the bottom 29 of the second elevator car 11 in the region of a central cross member 48 of the elevator car carrier 2. Further lowering of the second elevator car 11 relative to the elevator car carrier 2 is therefore not possible. The distance 47 shown therefore indicates a predetermined minimum distance 47. Here, the minimum distance 47 over the length of the traction means 22, 23 can be set within certain limits.

Zum Anheben der zweiten Aufzugkabine 11 relativ zu dem Aufzugkabinenträger 2 wird die Antriebsrolle 15 von der Antriebseinheit 14 angetrieben. In diesem Ausführungsbeispiel ist zum Anheben der zweiten Aufzugkabine 11 ein Antreiben der Antriebsrolle 15 entgegen dem Uhrzeigersinn erforderlich. Hierdurch verkürzt sich der Teil des zweiten Zugmittels 23, der sich einerseits zwischen der ersten Rollenanordnung 16 und der Befestigungsstelle 35 befindet. Hierbei kommt es zu einer entsprechenden Verlängerung des Teils des zweiten Zugmittels 23, das sich andererseits zwischen der zweiten Rollenanordnung 19 und der Befestigungsstelle 37 befindet. Da die Zugmittel 22, 23 gegensinnig um die Antriebsrolle 15 geführt sind, ist die Wirkung bezüglich des ersten Zugmittels 22 gerade entgegengesetzt. Das erste Zugmittel 22 läuft nämlich entgegen dem zweiten Zugmittel 23. Somit verlängert sich der Teil des ersten Zugmittels 22, der sich einerseits zwischen der ersten Rollenanordnung 16 und der Befestigungsstelle 25 befindet. Entsprechend kommt es zu einer Verkürzung des Teils des ersten Zugmittels 22, das sich andererseits zwischen der zweiten Rollenanordnung 19 und der Befestigungsstelle 28 befindet.For lifting the second elevator car 11 relative to the elevator car carrier 2, the drive roller 15 is driven by the drive unit 14. In this embodiment, for driving the second elevator car 11, it is necessary to drive the drive roller 15 in the counterclockwise direction. This shortens the part of the second traction means 23, which is located on the one hand between the first roller assembly 16 and the attachment point 35. This results in a corresponding extension of the part of the second traction means 23, which is on the other hand between the second roller assembly 19 and the attachment point 37. Since the traction means 22, 23 are guided in opposite directions about the drive roller 15, the effect with respect to the first traction means 22 is just opposite. Namely, the first traction means 22 runs counter to the second traction means 23. Thus, the part of the first traction means 22, which is located on the one hand between the first roller assembly 16 and the attachment point 25 extends. Accordingly, there is a shortening of the part of the first pulling means 22, which is on the other hand between the second roller assembly 19 and the attachment point 28.

Im Ergebnis wird die erste Aufzugkabine 10 aus der in der Fig. 1 dargestellten Ausgangsstellung abgesenkt, während die zweite Aufzugkabine 11 aus der in der Fig. 1 dargestellten Ausgangsstellung angehoben wird. Hierdurch vergrößert sich der Abstand 47 zwischen der ersten Aufzugkabine 10 und der zweiten Aufzugkabine 11. Außerdem ist ein Verstellweg der ersten Aufzugkabine 10 zumindest näherungsweise gleich groß wie ein Verstellweg der zweiten Aufzugkabine 11. Ferner werden die beiden Aufzugkabinen 10, 11 in zueinander entgegengesetzte Richtungen verstellt. Bei einer Vergrößerung des Abstands 47 wird die erste Aufzugkabine 10 nämlich nach unten verstellt und die zweite Aufzugkabine 11 wird nach oben verstellt.As a result, the first elevator car 10 is made of the in the Fig. 1 lowered starting position shown, while the second elevator car 11 from the in the Fig. 1 is raised starting position shown. In this way, the distance 47 between the first elevator car 10 and the second elevator car 11 increases. Furthermore, an adjustment path of the first elevator car 10 is at least approximately the same size as a displacement path of the second elevator car 11. Furthermore, the two elevator cars 10, 11 are adjusted in mutually opposite directions , With an increase in the distance 47, the first elevator car 10 is namely downwardly adjusted and the second elevator car 11 is moved upwards.

Umgekehrt kommt es bei einem Antreiben der Antriebsrolle 15 in entgegengesetzter Richtung, das heißt im Uhrzeigersinn, zu einem Absenken der zweiten Aufzugkabine 11, während die erste Aufzugkabine 10 angehoben wird. Hierdurch kann der Abstand 47 wieder verkürzt werden.Conversely, when the driving roller 15 is driven in the opposite direction, that is, clockwise, the second elevator car 11 is lowered while the first elevator car 10 is raised. As a result, the distance 47 can be shortened again.

Somit kann innerhalb gewisser Grenzen eine Variation des Abstands 47 durch Betätigen der Antriebsrolle 15 mittels der Antriebseinheit 14 erfolgen. Hierdurch ist eine Anpassung 47 an den jeweils vorgegebenen Stockwerksabstand der Zielstockwerke möglich.Thus, within certain limits, a variation of the distance 47 by pressing the drive roller 15 by means of the drive unit 14 done. As a result, an adaptation 47 to the respective predetermined floor distance of the destination floors is possible.

Das erste Zugmittel 22 und das zweite Zugmittel 23 werden an der Antriebsrolle 15 in vorteilhafter Weise mit Zugkräften beaufschlagt. Solche Zugkräfte ergeben sich insbesondere aus den Gewichtskräften der Aufzugkabinen 10, 11. Hierbei kommt es zu einem vorteilhaften Kräfteausgleich zwischen den Gewichtskräften der beiden Aufzugskabinen 10, 11. Dabei agiert die eine Aufzugskabine 10 als Gegengewicht der anderen Aufzugskabine 11. Somit hat die Antriebsrolle 15 zumindest im Wesentlichen nur ein Drehmoment auf die Zugmittel 22, 23 aufzubringen, das ausreicht, um die zwischen den beiden Aufzugskabinen 10, 11 unbalancierte Gewichtskraft sowie Systemreibungskräfte zu überwinden.The first traction means 22 and the second traction means 23 are applied to the drive roller 15 in an advantageous manner with tensile forces. Such tensile forces arise in particular from the weight forces of the elevator cars 10, 11. In this case, there is an advantageous balance of forces between the weight forces of the two elevator cars 10, 11. The one elevator car 10 acts as a counterweight to the other Elevator car 11. Thus, the drive roller 15 at least substantially only a torque on the traction means 22, 23 apply, which is sufficient to overcome the unbalanced between the two elevator cars 10, 11 weight and system friction forces.

Die Zugmittel 22, 23 können auch jeweils vollständig um die Antriebswelle 15 geführt sein. Speziell kann das erste Zugmittel 22 um zumindest 360° um die Antriebsrolle 15 geführt sein. Entsprechend kann auch das zweite Zugmittel 23 um zumindest 360° um die Antriebsrolle 15 geführt sein. Hierdurch kann ein guter Reibschluss zwischen jedem der Zugmittel 22, 23 und der Antriebsrolle 15 erzielt werden. Ein Schlupf zwischen den Zugmittel 22, 23 und der Antriebsrolle 15 kann hierdurch verhindert werden.The traction means 22, 23 can also be guided completely around the drive shaft 15 in each case. Specifically, the first traction means 22 may be guided around the drive roller 15 by at least 360 °. Accordingly, the second traction means 23 may be performed by at least 360 ° to the drive roller 15. In this way, a good frictional engagement between each of the traction means 22, 23 and the drive roller 15 can be achieved. Slippage between the traction means 22, 23 and the drive roller 15 can thereby be prevented.

Die Antriebseinheit 14 kann die Antriebsrolle 15 über ein Schneckengetriebe antreiben. Die Antriebseinheit 14 ist dann über ein Schneckengetriebe mit der Antriebsrolle 15 verbunden. Hierdurch können in zuverlässiger Weise auch kleine Bewegungen der Zugmittel 22, 23 erzielt werden. Hierdurch können kleine Betätigungswege der Aufzugkabinen 10, 11 zum Ändern des Abstands 47 erreicht werden. Speziell kann die Antriebseinheit 14 mit der Antriebsrolle 15 hierdurch so ausgelegt werden, dass bei einer normalen Umdrehungsgeschwindigkeit der Antriebseinheit 14 auch kleine Verstellbewegungen der Aufzugkabinen 10, 11 relativ zu dem Aufzugkabinenträger 2 möglich sind. Auf diese Weise kann durch die Verstelleinrichtung 40 auch eine 1:1-Verstellung ermöglich werden, bei der eine geringe Verlustreibung auftritt und relativ kurze Zugmittel 22, 23 ausreichen.The drive unit 14 can drive the drive roller 15 via a worm gear. The drive unit 14 is then connected to the drive roller 15 via a worm gear. As a result, even small movements of the traction means 22, 23 can be achieved in a reliable manner. As a result, small actuation paths of the elevator cars 10, 11 for changing the distance 47 can be achieved. Specifically, the drive unit 14 with the drive roller 15 can thereby be designed so that at a normal rotational speed of the drive unit 14 and small adjustment movements of the elevator cars 10, 11 relative to the elevator car carrier 2 are possible. In this way, a 1: 1 adjustment can be made possible by the adjustment 40, in which a low loss of friction occurs and relatively short traction means 22, 23 sufficient.

Somit kann die Antriebseinheit 14 relativ klein ausgestaltet sein und eine optimierte Leistungsfähigkeit aufweisen. Hierbei können in Bezug auf die Leistungsfähigkeit der Antriebseinheit 14 relativ große Verstellwege zwischen den beiden Aufzugkabinen 10, 11, insbesondere von zwei oder mehr Metern, realisiert werden.Thus, the drive unit 14 can be made relatively small be and have an optimized performance. In this case, in relation to the performance of the drive unit 14, relatively large displacement paths between the two elevator cars 10, 11, in particular of two or more meters, can be realized.

In vorteilhafter Weise kann eine 1:1-Aufhängung realisiert werden, die von einem kleinen Motor der Antriebseinheit 14 betätigt wird. Beispielsweise kann die Leistung der Antriebseinheit 14 im Bereich von 2 kW bis 5 kW liegen. Hierdurch können beispielsweise Aufzugkabinen 10, 11 betätigt werden, die jeweils eine Masse von 2250 kg haben. Somit ergibt sich ein großer Anwendungsbereich für die Aufzuganlage 1.Advantageously, a 1: 1 suspension can be realized, which is actuated by a small motor of the drive unit 14. For example, the power of the drive unit 14 may be in the range of 2 kW to 5 kW. As a result, for example elevator cars 10, 11 are operated, each having a mass of 2250 kg. This results in a large field of application for the elevator installation 1.

Alternativ sind höhere Aufhängungsverhältnisse von 2:1, 3:1 oder auch höher realisierbar.Alternatively, higher suspension ratios of 2: 1, 3: 1 or higher can be realized.

Ferner kann eine weitere Verstelleinrichtung 41 vorgesehen sein. Die weitere Verstelleinrichtung 41 kann im Wesentlichen entsprechend der Verstelleinrichtung 40 ausgestaltet sein und verfügt im Wesentlichen über die gleiche zuvor für die Verstelleinrichtung 40 beschriebene Funktionsweise zum Einstellen des Abstandes 47 zwischen den Aufzugskabinen 10, 11. Insbesondere können ein drittes Zugmittel 42 und ein viertes Zugmittel 43 sowie eine in Fig. 1 nicht dargestellte, vom Aufzugskabinenträger 2 abgedeckte weiteren Antriebsrolle vorgesehen sein. Die Zugmittel 42, 43 stehen dabei in Wirkkontakt mit der weiteren Antriebsrolle. Hierbei kann eine Verbindungswelle 44 die Antriebseinheit 14 mit der weiteren Verstelleinrichtung 41 verbinden. Hierdurch kann die Antriebseinheit 14 zum Antreiben sowohl der Komponenten der Verstelleinrichtung 40 als auch der Komponenten der weiteren Verstelleinrichtung 41 dienen. Somit kann über die Antriebseinheit 14 zum einen eine Betätigung des ersten Zugmittels 22 und des zweiten Zugmittels 23 der Verstelleinrichtung 40 als auch eine Betätigung des dritten Zugmittels 42 als auch des vierten Zugmittels 43 der weiteren Verstelleinrichtung 41 erfolgen.Furthermore, a further adjusting device 41 may be provided. The further adjusting device 41 may be designed substantially in accordance with the adjusting device 40 and has substantially the same operation previously described for the adjustment 40 for adjusting the distance 47 between the elevator cars 10, 11. In particular, a third traction means 42 and a fourth traction means 43rd as well as an in Fig. 1 not shown, be covered by the elevator car carrier 2 covered further drive roller. The traction means 42, 43 are in operative contact with the further drive roller. In this case, a connecting shaft 44 can connect the drive unit 14 with the further adjusting device 41. In this way, the drive unit 14 for driving both the components of the adjusting device 40 and the components of the other Adjustment 41 serve. Thus, via the drive unit 14, on the one hand, an actuation of the first traction mechanism 22 and of the second traction mechanism 23 of the adjustment device 40 as well as an actuation of the third traction mechanism 42 and the fourth traction mechanism 43 of the further adjustment device 41 can take place.
