If now an average distance from the connecting devices 20 of the first row 17 to the axis of rotation 12 equal to an average distance he connecting devices 20 of the second row 18, the resulting torques in both directions of rotation of the carrier 10 are equal, provided that all support means 11 with the same Pull force and in the same direction on the connecting devices 20.
- the connecting devices 20 may also be arranged asymmetrically on the carrier 10, the resulting torque on the carrier 10 being in a normal state, i. without temporary differences in tension between the suspension elements, also equal to zero.
- one row may comprise fewer connecting devices than the other row but have a greater average distance from the axis of rotation than the other row.
- the individual connecting devices of a row can have a different distance from the axis of rotation.
- the rows may therefore be oblique to the rotation axis, or individual connection devices may deviate from a line laid through the row.
- the pulling direction of the support means 11, which act on the support means attachment 40 can change (see FIG. 1 ). Due to the rotatable mounting of the suspension element fastening device 40, this always aligns itself so that the connecting devices 20 are each parallel to the pulling direction of the suspension element 11. Thereby the mechanical load of the support means 11 and the connecting devices 20 and the carrier 10 is reduced, allowing a longer service life of these components.

Alternativ zu einer Befestigung an der Schachtwand 3 kann die Tragmittelbefestigung 40 auch an einer Führungsschiene oder an einer im Schacht 2 angeordneten Tragkonstruktion oder an einer zusätzlichen Hilfskonstruktion angeordnet sein (nicht gezeigt).As an alternative to attachment to the
Die Tragmittelbefestigungsvorrichtung 40 wird vorzugsweise im Schacht 2 einer Aufzugsanlage 1 montiert, z.B. an einer Schachtwand 3. Dies ist der Fall, wenn die Kabine 4 und das Gegengewicht 5 an Umlenkrollen 6 von den Tragmitteln 11 getragen werden. Bei Aufzugsanlagen, an denen die Kabine und/oder das Gegengewicht direkt mit den Tragmitteln verbunden sind, kann die erfindungsgemässe Tragmittelbefestigungsvorrichtung an der Kabine und oder am Gegengewicht befestigt werden (nicht gezeigt).The

Der Träger 10 kann grundsätzlich in einer beliebigen Form ausgebildet sein. Bevorzugt weist der Träger eine zylindrische Form auf. Vorteilhaft sind gerade Zylinderformen, besonders vorteilhaft ist ein gerader Kreiszylinder. Der in
Der Träger 10 kann alternativ dazu auch in anderer Form ausgestaltet sein, z.B. als Quader oder als Platte oder als Verbindung von mehreren Balken und oder Platten (nicht dargestellt).The

Um die Befestigung der Verbindungsvorrichtungen am Träger zu vereinfachen, kann am Träger eine Montagefläche 15 vorgesehen sein. Diese ist vorzugsweise so ausgestaltet, dass die Verbindungsvorrichtungen senkrecht zu dieser Montagefläche 15 angeordnet sind. Der runde Querschnitt des Trägers 10 ist an einer Stelle segmentartig abgeschnitten, wodurch die Montagefläche 15 entsteht.In order to simplify the attachment of the connecting devices on the carrier, a mounting
Die Montagefläche 15 wird seitlich durch einen ersten Rand 41 und einen zweiten Rand 42 begrenzt, und weist in ihrer Mitte in Längsrichtung eine Mittellinie 43 auf.The mounting
Die Montagefläche 15 kann wie in
Die im Träger 10 vorgesehenen Durchführungen 16 sind in zwei Reihen angeordnet, einer ersten Reihe 17 und einer zweiten Reihe 18. Jeweils eine Öffnung der Durchführungen 16 liegt auf der Montagefläche 15. Die erste Reihe 17 und die zweite Reihe 18 sind symmetrisch auf gegenüberliegenden Seiten der Mittellinie 43 der Montagefläche 15 angeordnet. Sie liegen parallel zueinander und parallel zur Mittellinie 43. Die erste Reihe 17 und die zweite Reihe 18 weisen gleich viele Durchführungen 16 auf, in der gezeigten Ausführungsform weist jede Reihe je zwölf. Die Durchführungen 16 der ersten Reihe 17 sind im gezeigten Beispiel versetzt zu den Durchführungen 16 der zweiten Reihe 18 angeordnet.The
An zwei sich gegenüberliegenden Seiten des Trägers befindet sich je eine Rotationsfläche 14. Da der Träger 10 in der gezeigten Ausführungsform einen runden Querschnitt aufweist, sind die Rotationsflächen 14 kreisförmig.On two opposite sides of the carrier is ever a surface of
An jeder Rotationsfläche 14 befindet sich eine Lagervorrichtung 13, um den Träger 10 drehbar zu befestigen. Die Lagervorrichtungen 13 sind als Aussparungen ausgebildet, in welche ein Gegenstück eingreifen kann.On each surface of
Der an den zwei Lagervorrichtungen 13 befestigbare Träger 10 weist eine Rotationsachse 12 auf, welche durch beide Lagervorrichtungen 13 hindurchreicht. Die Rotationsachse 12 und die Mittellinie 43 der Montagefläche 15 liegen in dieser Draufsicht von oben auf den Träger 10 übereinander.The mountable to the two
Der Träger hat vorzugsweise eine längliche Form. Eine Länge des Trägers 10 liegt dabei bevorzugt in einem Bereich von 10 cm bis 100 cm, besonders bevorzugt zwischen 25 cm und 75 cm. Ein Durchmesser des Querschnittes des Trägers 10 misst vorzugsweise zwischen 4 cm und 14 cm, besonders bevorzugt zwischen 6 cm und 11 cm.The carrier preferably has an elongated shape. A length of the
Ein Durchmesser der Durchführungen 16 ist abhängig von einem Durchmesser der Verbindungsvorrichtunge, welche durch die Durchführugne 16 geführt werden. Dieser Durchmesser misst vorzugsweise zwischen 0.3 und 2 cm, besonders bevorzugt zwischen 0.6 und 1.4 cm.A diameter of the
Ein Abstand zwischen der ersten Reihe 17 und der zweiten Reihe 18 ist abhängig vom Durchmesser des Querschnittes des Trägers 10. Dieser Abstand beträgt vorzugsweise zwischen 2 cm und 8 cm, besonders bevorzugt zwischen 3.5 cm und 6.5 cm.A distance between the
Die
Der Träger 10 ist vorzugsweise länglich und dünn ausgebildet, um möglichst wenig Platz in der Aufzugsanlage zu beanspruchen. Dennoch muss er genügend robust ausgebildet sein. Um einen optimalen Halt für die im Träger 10 gesicherten Verbindungsvorrichtungen zu gewährleisten, ist der Träger 10 vorzugsweise ein massiver (voller) Körper. Der in
Bevorzugtes Material für den Träger ist Stahl, es können jedoch auch andere geeignete Materialien zur Anwendung kommen. Ein Träger aus Stahl kann zudem beschichtet werden, so dass ein Gleiten in der Lagerung des Trägers verbessert wird. Der Träger kann auch als hohler Körper mit einer genügend grossen Wandstärke ausgebildet sein (nicht dargestellt).Preferred material for the carrier is steel, but other suitable materials may be used. In addition, a steel beam can be coated to improve sliding in the bearing of the beam. The carrier may also be formed as a hollow body with a sufficiently large wall thickness (not shown).
Die
Die Durchführungen 16 reichen durch den Trägerkörper 19 hindurch. Jeweils eine Öffnung liegt auf der Montagefläche 15 und die andere Öffnung auf der der Montagefläche 15 abgewandten Seite des Trägers 10.The
Diese Durchführungen 16 sind, wie in
Die Durchführungen können jedoch auch anders gestaltet sein. In einer nicht dargestellten Ausführungsform können anstatt Bohrungen auch Einbuchtungen oder Einschnitte an Seitenwänden des Trägers 10 verwendet werden, wobei nach dem Einlegen der Verbindungsvorrichtungen in diese Einbuchtungen z.B. eine Platte auf die Seitenwand fixiert werden kann, so dass die so entstandenen Durchführungen den Verbindungsvorrichtungen genügend Halt bieten.However, the bushings can also be designed differently. In an embodiment which is not shown, it is also possible to use indentations or cuts on side walls of the
Die Durchführungen sind vorzugsweise im Wesentlichen parallel zueinander angeordnet. Dadurch liegen im Wesentlichen alle der im Träger gesicherten Verbindungsvorrichtungen parallel zu einer allgemeinen Zugrichtung der Tragmittel.The passages are preferably arranged substantially parallel to one another. As a result, substantially all of the connecting devices secured in the carrier lie parallel to a general pulling direction of the suspension elements.
Die Durchführungen 16 sollten in genügend grossen Abständen zu den Aussenwänden des Trägers vorgesehen sein, um die Verbindungsvorrichtungen sicher aufzunehmen. Andererseits sollen die Durchführungen 16 nicht zu nahe an der Rotationsachse 12 des Trägers 10 angeordnet sein, damit auftretende Spannungsunterschiede zwischen den Tragmitteln zu genügend grossen Drehmomenten am Träger 10 führen, so dass eine Rotationsbewegung des Trägers 10 zum Ausgleich der Spannungsunterschiede stattfinden kann.
In einer bevorzugten Ausführungsform ist demnach ein Abstand 44 von einem Rand der Montagefläche bis zu einer Reihe der Durchführungen kleiner als ein Abstand 45 von einer Mittellinie bis zu einer Reihe der Durchführungen.The
Accordingly, in a preferred embodiment, a
In
Die Durchführungen 16 können wie in
Die Verbindungsvorrichtungen 20 dienen dazu, die Tragmittel 11 am Träger 10 zu befestigen. Vorzugsweise weisen die Verbindungsvorrichtungen 20 eine längliche Form auf. Die Verbindungsvorrichtungen 20 weisen ein erstes Ende 21 und ein zweites Ende 29 auf. Das erste Ende 21 dient der Befestigung am Träger 10. Das zweite Ende 29 dient der Befestigung der Tragmittel 11 an der Verbindungsvorrichtung 20.The connecting
Der längliche Körper der Verbindungsvorrichtungen 20 weist vorzugsweise einen runden Querschnitt auf. Es können dabei dickere und dünnere Abschnitte vorgesehen sein. Ein runder Querschnitt erleichtert das Durchführen der Verbindungsvorrichtungen 20 durch die Durchführungen 16 im Träger 10. Die Verbindungsvorrichtungen 20 bestehen bevorzugt aus zugfestem Material, z.B. aus Stahl. Es können jedoch auch flexible Materialien zum Einsatz kommen, vorausgesetzt dass diese keine oder nur eine geringe Dehnbarkeit in Zugrichtung der Tragmittel 11 aufweisen. Der Körper der Verbindungsvorrichtungen 20 kann beispielsweise als Gewindestange ausgebildet sein. Solch eine Gewindestange weist zumindest an einem ihrer Enden ein Gewinde auf, das Gewinde kann sich jedoch auch über die gesamte Länge der Gewindestange erstrecken.The elongate body of the connecting
Die Verbindungsvorrichtungen 20 sind durch jeweils eine Durchführung 16 geführt, und auf der Montagefläche 15 in Zugrichtung der Tragmittel 11 gesichert.The connecting
Ein erstes Ende 21 dieser länglichen Verbindungsvorrichtungen 20 ist derart ausgebildet, dass es die Verbindungsvorrichtung 20 am Träger 10 zu befestigen vermag. Dies kann beispielsweise mit einer Gewindestange und einer Mutter 23 erreicht werden, jedoch sind hier auch andere Ausführungsformen denkbar, wie z.B. hackenartige Enden. Alternativ können die ersten Enden 21 auch am Träger 10 eingegossen werden, so dass eine permanente Verbindung zwischen Träger 10 und Verbindungsvorrichtungen 20 entsteht.A
Vorteilhafterweise sind die ersten Enden 21 gefedert am Träger 10 gesichert, so dass die Tragmittel 11 mit einer gewissen Vorspannung montiert werden können. Dazu kann eine Feder 24, welche wie in
Auf den den ersten Enden 21 gegenüberliegenden Seiten der länglichen Verbindungsvorrichtungen 20 liegen die zweiten Enden 29. Hier werden die Tragmittel 11 an den Verbindungsvorrichtungen 20 festgemacht. Am zweiten Ende 29 der Verbindungsvorrichtungen 20 ist in einem Ausführungsbeispiel ein Adapter 28 für ein Keilschloss 29 angebracht. Die Keilschlösser 45 nehmen die Riemen 30 auf und sind ihrerseits am Adapter 28 der Verbindungsvorrichtung 20 befestigt. Der Adapter 28 kann dabei so ausgestaltet sein, dass die Keilschlösser 45 beweglich, z.B. mit Hilfe eines Kugelgelenkes, an der Verbindungsvorrichtung 20 befestigt sind.On the opposite ends of the first ends 21 of the elongated connecting
Wie in
Die drehbare Befestigung des Trägers 10 kann auf verschiedene Arten realisiert werden. Demnach können die Lagervorrichtungen 13 verschiedenartig ausgestaltet sein. Wie in
In einer alternativen, nicht dargestellten Ausführungsform können die Lagervorrichtungen 13 auch als Bolzen ausgeführt sein, welche ihrerseits in Lager aufgenommen werden. Die Lagervorrichtungen können ferner auch nur als Gewinde gestaltet sein, in welche ein Lager oder ein Bolzen verschraubt werden kann.In an alternative, not shown embodiment, the bearing
Die Lagerung muss nicht eine uneingeschränkte Rotation des Trägers 10 ermöglichen. Zur Lösung der erfindungsgemässen Aufgabe reichen vorzugsweise einige Grad Drehwinkel aus. Demzufolge kann die Rotation auf einige Grad in jede Drehrichtung, ausgehend von einer neutralen Stellung, beschränkt werden, und/oder die Rotation kann mit geeigneten Mitteln gedämpft werden.The storage does not have to allow unrestricted rotation of the
An den Rotationsflächen 14 befinden sich Führungselemente 46. In der gezeigten Ausführungsform sind diese Führungselemente 46 als nutartige Vertiefungen am Rand der Rotationsflächen 14 ausgebildet. Ein nicht gezeigtes Gegenstück, welches nicht mit dem Träger 10 mitrotiert, greift in diese nutartige Vertiefung ein und kann so den Träger 10 führen und stabilisieren, wenn dieser eine Rotationsbewegung um seine Rotationsachse ausführt.
In einer nicht dargestellten alternativen Ausführungsform sind die Führungselemente am Träger als Bolzen ausgebildet, welche in nicht mit dem Träger rotierende Schienen eingreifen und bei einer Rotation von diesen Schienen geführt werden.In the embodiment shown, these
In an alternative embodiment, not shown, the guide elements are formed on the carrier as bolts, which engage in non-rotating with the carrier rails and are guided during rotation of these rails.
In
Hier ist ersichtlich, wie in einer beispielhaften Ausführungsform die Riemen 30 in von den Keilschlössern 45 gehalten werden. Zudem ist ersichtlich, dass die Verbindungsvorrichtungen 20 nicht in der Mitte des Trägers 10 angeordnet sind, sondern nach aussen, so dass die Verbindungsvorrichtungen 20 mit einem grösseren Hebelarm am Träger 10 wirksam werden.In
Here it can be seen how in an exemplary embodiment the
Vorzugsweise gleichen sich Drehmomente, welche durch die Verbindungsvorrichtungen 20 der ersten Reihe 17 am Träger 10 wirksam sind, und Drehmomente, welche durch die Verbindungsvorrichtungen 20 der zweiten Reihe 18 am Träger 10 wirksam sind, aus. Demnach führt der Träger in einem Normalzustand, d.h. wenn die Drehmomente in beide Drehrichtungen gleich gross sind, keine Rotationsbewegung aus. Dies ist normalerweise der Fall, wenn die Aufzugskabine nicht bewegt wird.Preferably, torques acting on the
Eine neutrale Stellung, welche solch einen Normalzustand ermöglicht, kann durch verschiedene Anordnungen der Verbindungsvorrichtungen 20 am Träger 10 erreicht werden. Wie in
Alternativ zu solch einer symmetrischen Anordnung können die Verbindungsvorrichtungen 20 auch asymmetrisch am Träger 10 angeordnet werden, wobei das resultierende Drehmoment am Träger 10 in einem Normalzustand, d.h. ohne temporäre Spannungsunterschiede zwischen den Tragmitteln, ebenfalls gleich null ist. In einer beispielhaften Ausführungsform kann eine Reihe weniger Verbindungsvorrichtungen umfassen als die andere Reihe, dafür aber einen grösseren durchschnittlichen Abstand zur Rotationsachse aufweisen als die andere Reihe. Oder die einzelnen Verbindungsvorrichtungen einer Reihe können einen unterschiedlichen Abstand zur Rotationsachse aufweisen. Beispielsweise können die Reihen demnach schräg zur Rotationsachse stehen, oder es können einzelne Verbindungsvorrichtungen von einer durch die Reihe gelegten Geraden abweichen.As an alternative to such a symmetrical arrangement, the connecting
Bei Ausführungsformen, in denen nicht alle Verbindungsvorrichtungen den gleichen Abstand zur Rotationsachse aufweisen, ist zu beachten, dass Spannungsunterschiede in Tragmitteln, welche an einer Verbindungsvorrichtung, die einen grösseren Abstand zur Rotationsachse aufweist, befestigt sind, ein grösseres Drehmoment auf den Träger ausüben und gegebenenfalls zu einer grösseren Rotationsbewegung des Trägers führen. Dieser Effekt kann erwünscht sein, falls z.B. einzelne Tragmittel aufgrund ihrer Lage in der Aufzugsanlage zu stärkeren Schwankungen in ihrer Spannung neigen.In embodiments in which not all connecting devices are equidistant from the axis of rotation, it should be noted that differences in tension in suspension elements, which are fastened to a connecting device which is a greater distance from the axis of rotation, exert a greater torque on the carrier and possibly also lead to a greater rotational movement of the carrier. This effect may be desirable if e.g. Due to their position in the elevator installation, individual suspension elements tend to have greater fluctuations in their tension.
Während dem die Kabine 4 und das Gegengewicht 5 verfahren werden, kann sich die Zugrichtung der Tragmittel 11, welche an der Tragmittelbefestigung 40 wirken, verändern (siehe
