Abstract
Description
Die Erfindung betrifft einen Aufzug mit einer Aufzugskabine und einem Gegengewicht, die in einem Aufzugsschacht mittels Tragmitteln gegenläufig auf und ab bewegbar sind, und mit Ausgleichsmitteln, die die Aufzugskabine und das Gegengewicht verbinden und die ein sich änderndes Gewicht der Tragmittel auf der Kabinenseite und auf der Gegengewichtsseite ausgleichen, wobei eine Führungseinrichtung vorgesehen ist, die die Ausgleichsmittel führt und stabilisiert.The invention relates to an elevator with an elevator car and a counterweight which are reciprocally movable in an elevator shaft by means of support means and with counterbalancing means connecting the elevator car and the counterweight and the changing weight of the suspension means on the cabin side and on the Balance counterweight side, wherein a guide means is provided, which guides and stabilizes the compensating means.
Aus der Schrift
Nachteilig bei der bekannten Einrichtung ist, dass bei sprunghaften Bewegungen der Ausgleichsmittel die Führungseinrichtung beschädigt werden kann.A disadvantage of the known device is that in sudden movements of the compensating means, the guide device can be damaged.
Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Einrichtung zu schaffen, die die Ausgleichsmittel führt ohne Schaden zu nehmen.The invention aims to remedy this situation. The invention as characterized in
Die durch die vorgeschlagene Einrichtung erreichten Vorteile sind im Wesentlichen darin zu sehen, dass weniger tiefe Schachtgruben möglich sind als bei herkömmlichen Führungseinrichtungen der Ausgleichsmittel. Eine Schachtgrubentiefe von etwas mehr als der Radius der Ausgleichsmittelschlaufe genügt. Die Einrichtung ist einfach im Aufbau, kostengünstig und kann nachgerüstet werden unabhängig von der Schachtgrubentiefe. Ausserdem passt die Einrichtung auf unterschiedlich aufgebaute Ausgleichsmittel.The advantages achieved by the proposed device are essentially to be seen in the fact that less deep shaft pits are possible than in conventional guide means of the compensating means. A shaft pit depth of slightly more than the radius of the compensating means loop is sufficient. The device is simple in construction, inexpensive and can be retrofitted regardless of the shaft pit depth. In addition, the device fits differently constructed compensating means.

Je nach Lage der Aufzugskabine 3 und des Gegengewichts 4 im Aufzugsschacht 2 sind mehr Meter der Tragmittel 7 auf der Kabinenseite oder auf der Gegengewichtsseite. Die einenends unter der Aufzugskabine 3 an einem ersten Punkt 9 und anderenends unter dem Gegengewicht 4 an einem zweiten Punkt 10 angeordneten Ausgleichsmittel 8 wirken in Sachen Länge bzw. Gewicht auf der Kabinenseite und auf der Gegengewichtsseite gegenläufig zur Länge bzw. zum Gewicht der Tragmittel auf der Kabinenseite und auf der Gegengewichtsseite. Bei wenig Tragmittellänge auf der Kabinenseite ergibt sich viel Ausgleichsmittellänge auf der Kabinenseite und umgekehrt. Die an der Aufzugskabine 3 und am Gegengewicht 4 aufgehängten Ausgleichsmittel 8 bilden in einer Schachtgrube 11 eine Schlaufe 12 und können insbesondere bei grosser Förderhöhe in Schwingungen versetzt werden. Als Abhilfe ist eine Führungseinrichtung vorgesehen, die die Ausgleichsmittel 8 in der Ebene E führt und stabilisiert.Depending on the position of the
Die Ausgleichsmittel 8 bestehen auf der Kabinenseite aus einem lotrechten, ersten Strang 13 und auf der Gegengewichtsseite aus einem lotrechten, zweiten Strang 14 und in der Schachtgrube 11 aus der Schlaufe 12.

Das erste Leitelement 15 ist zwischen den Ausgleichsmitteln 8 und einer Schachtwand 17 und das zweite Leitelement 16 ist zwischen den beiden lotrechten Strängen 13, 14 bzw. innerhalb der Schlaufe 12 angeordnet. Üblicherweise ist das erste Leitelement 15 entlang des Weges der Ausgleichsmittel 8 auf der Gegengewichtsseite angeordnet so dass das Gegengewicht 4 vorbeifahren kann. Mindestens ein erstes Leitelement 15 kann insbesondere bei grossen Förderhöhen auch auf der Kabinenseite vorgesehen sein. In diesem Fall ist das Leitelement wegschwenkbar, damit die Aufzugskabine 3 vorbeifahren kann. In
