Description

Die vorliegende Erfindung hat einen mit einem Fahrkorb ausgestatteten Aufzug zum Gegenstand, bei dem der Fahrkorb über einen Tragseilzug mit einem Gegengewicht verbunden ist, an dem der Kurzstator eines Linearmotors angeordnet ist, dessen als Magnetleiste ausgebildeter Reaktionsteil dann an der Schachtwand des Aufzuges befestigt ist.The subject of the present invention is an elevator equipped with a car, in which the car is connected to a counterweight via a suspension cable, on which the short stator of a linear motor is arranged, the reaction part of which is designed as a magnetic strip and is then fastened to the shaft wall of the elevator.

Die Anwendung eines Linearmotors als Antrieb für einen Aufzug ist bereits seit langem bekannt. Im allgemeinen wird hierzu jedoch ein Linear-Asynchronmotor verwendet. Ein solcher Asynchronmotor benötigt jedoch sehr geringe Luftspalte zwischen dem Stator und dem Reaktionsteil, was wieder eine hohe Fertigungsgenauigkeit der einzelnen Bauelemente sowie auch eine exakte Montage des Reaktionsteiles im Aufzugsschacht erforderlich macht.The use of a linear motor as a drive for an elevator has been known for a long time. In general, however, a linear asynchronous motor is used for this. However, such an asynchronous motor requires very small air gaps between the stator and the reaction part, which in turn necessitates high manufacturing accuracy of the individual components and also exact assembly of the reaction part in the elevator shaft.

Aufgabe der vorliegenden Erfindung ist es nunmehr, diesen bisher bestehenden Übelstand zu beseitigen und die daraus bedingten Nachteile zu vermeiden.The object of the present invention is now to eliminate this previously existing problem and to avoid the disadvantages resulting therefrom.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Linearmotor als Synchronmotor ausgebildet und In das Gegengewicht integriert ist, wobei dann der Fahrkorb exzentrisch an dem Tragseilstrang befestigt ist. Diese exzentrische Befestigung des Tragseilstranges an dem Fahrkorb, die auch als sogenannte Rucksackführung bezeichnet wird, erlaubt vor allem eine einfache Führung der Aufzugsseile, die vom Seilfestpunkt des Gegengewichtes über eine Seilumlenkrolle am oberen Aufhängeträger im Schachtkopf zum Seilfestpunkt am Fahrkorb verlaufen und sich nahezu in einer einzigen Ebene befindet. Dieser Seilverlauf ermöglicht dabei für die Seilumlenkrolle sowie die Führung des Fahrkorbes und Gegengewichts eine Tragkonstruktion, die sich durch eine besonders einfache und damit auch eine genaue Montage auszeichnet.This object is achieved in that the linear motor is designed as a synchronous motor and is integrated in the counterweight, the car then being attached eccentrically to the suspension cable strand. This eccentric attachment of the suspension cable strand to the car, which is also referred to as the so-called backpack guide, allows, above all, simple guidance of the elevator ropes, which run from the rope fixed point of the counterweight via a rope deflection roller on the upper suspension bracket in the shaft head to the rope fixed point on the car and are almost all in one Level. This course of the rope enables a supporting structure for the rope deflection roller as well as the guidance of the elevator car and counterweight, which is characterized by a particularly simple and thus also an exact assembly.

In diesem Zusammenhang ist es von Vorteil, wenn die aus Permanentmagneten gebildete Magnetleiste des Reaktionsteils dann an den Querverbindern einer dem Fahrkorb zugeordneten Führungsvorrichtung befestigt ist. Diese Führungsvorrichtung kann dabei als ein in sich geschlossener, an der Schachtwand befestigter Tragrahmen ausgebildet sein, der alle beim Betrieb des Aufzuges auftretenden Kräfte aufnimmt und an die Schachtwand und Schachtgrube weitergibt.In this context, it is advantageous if the magnetic strip of the reaction part formed from permanent magnets is then fastened to the cross connectors of a guide device assigned to the car. This guide device can be designed as a self-contained support frame attached to the shaft wall, which absorbs all the forces that occur during operation of the elevator and transmits them to the shaft wall and shaft pit.

Ferner ist es noch zweckmäßig, wenn der Tragrahmen zusammen mit den Führungsschienen, den Querverbindern, der an diesem befestigten Magnetleiste und dem Gegengewicht dann ein einheitliches und in sich geschlossenes Bauelement bildet. Durch die erfindungsgemäß verschlagene Anordnung der Elemente wird eine sehr kompakte, platzsparende und leicht zu montierende Antriebs-und Führungseinheit für einen Aufzug geschaffen.Furthermore, it is also expedient if the support frame together with the guide rails, the cross connectors, the magnetic strip fastened to this and the counterweight then forms a uniform and self-contained component. The arrangement of the elements, which is in accordance with the invention, creates a very compact, space-saving and easy-to-assemble drive and guide unit for an elevator.

Weitere Einzelheiten zu der vorliegenden Erfindung ergeben sich aus der nach folgender Beschreibung einer beispielsweisen Ausführungsform sowie den nachgestellten Ansprüchen. Es zeigen:

  • Fig. 1 eine schaubildliche und schematische Darstellung des Aufzuges und
  • Fig. 2 einen Querschnitt des Aufzugsschachtes.
Further details on the present invention will become apparent from the description of an exemplary embodiment which follows and the claims which follow. Show it:
  • Fig. 1 is a diagrammatic and schematic representation of the elevator and
  • Fig. 2 shows a cross section of the elevator shaft.

Der in der Fig. 1 schaubildlich dargestellte Aufzug 1 ist in einem mit 2 bezeichneten Aufzugsschacht untergebracht und weist einen Fahrkorb 3 auf, der über einen Tragseilzug 4 mit einem Gegengewicht 5 verbunden ist. Der Führung des Fahrkorbes 3 dient eine mit 6 bezeichnete Führungsvorrichtung, die aus zwei vertikalen Führungsschienen 7 und mehreren, diese miteinander verbindenden Querverbindern 8 besteht. Am Kopf 9 dieser Führungsvorrichtung 6 befindet sich ein mit 10 bezeichneter Aufhängeträger, der der Lagerung einer Seilumlenkrolle 11 des Tragseilzuges 4 dient.The elevator 1 shown diagrammatically in FIG. 1 is accommodated in an elevator shaft denoted by 2 and has a car 3 which is connected to a counterweight 5 via a carrying cable 4. The car 3 is guided by a guide device denoted by 6, which consists of two vertical guide rails 7 and a plurality of cross connectors 8 connecting them. At the head 9 of this guiding device 6 there is a suspension support, designated 10, which serves to mount a cable deflection roller 11 of the supporting cable 4.

Angetrieben wird der Aufzug 1 mittels eines als Synchronmotor ausgebildeten Linearmotors, dessen Kurzstator 12 in der in der Fig. 2 gezeigten Weise an der Rückseite 13 des zuvor schon erwähnten Gegengewichtes 5 in einer Nische 14 angeordnet ist. Diesem Kurzstator 12 ist als Reaktionsteil eine im Querschnitt U-förmige Magnetleiste 15 zugeordnet, in die der Kurzstator 12 hineinragt und die, wie aus den Fign. 1 und 2 ersichtlich ist, an den die Führungsschiene 7 miteinander verbindenden Querverbindern 8 befestigt ist.The elevator 1 is driven by means of a linear motor designed as a synchronous motor, the short stator 12 of which is arranged in the manner shown in FIG. 2 on the rear side 13 of the previously mentioned counterweight 5 in a niche 14. As a reaction part, this short stator 12 is assigned a magnetic strip 15 with a U-shaped cross section, into which the short stator 12 projects and which, as shown in FIGS. 1 and 2 can be seen, on which the crossbar 8 connecting the guide rail 7 is fastened.

Wie insbesondere aus der Fig. 2 ersichtlich ist, so bilden die Führungsschienen 7, die Querbinder 8 zusammen mit dem oberen Aufhängeträger 10 und einem Bodenträger 16 einen in sich geschlossenen Rahmen, der sowohl der Rucksackführung des Fahrkorbes 3 als auch der Führung des Gegengewichtes 5 dient. Die an dem Fahrkorb 3 und dem Gegengewicht 5 befindlichen Seilfestpunkte 17 und 18 sind dabei so angeordnet, daß der Tragseilzug 4 etwa in der gleichen Ebene wie auch die Umlenkrolle 11 liegt.As can be seen in particular from FIG. 2, the guide rails 7, the transverse ties 8 together with the upper suspension bracket 10 and a floor bracket 16 form a self-contained frame which serves both to guide the backpack of the car 3 and to guide the counterweight 5 . The fixed cable points 17 and 18 located on the car 3 and the counterweight 5 are arranged in such a way that the carrying cable 4 lies approximately in the same plane as the deflecting roller 11.
