Aus der Patentschrift
Ein Nachteil der bekannten Einrichtung liegt darin, dass mit getrennten Tragmitteln und Treibmitteln hohe Herstellungskosten entstehen. Zudem funktioniert der Aufzug nur bei korrekt gespanntem Zahnriemen zuverlässig. ' Ausserdem muss das Problem der Energiezuführung zum Gegengewicht mit Schleppkabeln gelöst werden.A disadvantage of the known device is that high production costs arise with separate support means and propellants. In addition, the elevator works reliably only with correctly tensioned toothed belt. 'In addition, the problem of energy supply to the counterweight with trailing cables must be solved.
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 einen konkurrenzfähigen Aufzug mit mechanischem Linearantrieb und vorzugsweise riemenförmigem Treibmittel zu schaffen. Dabei braucht die Laufrichtung des Treibmittels durch den Linearantrieb selbst nicht geändert zu werden. Nur wenn es aufgrund der Platzverhältnisse im Schacht zweckmässig erscheint, wird eine entsprechende Umlenkung im Linearantrieb selbst vorgesehen.The invention aims to remedy this situation. The invention, as characterized in
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der Linearantrieb entlang des Treibmittels platzsparend anbringbar ist. Der Schachtkopf eignet sich besonders für unterschiedliche Anordnungsvarianten und Treib- bzw. Trägmittelführungsvarianten. Der Linearantrieb kann je nach Leistung und mechanischen Abmessungen im Schachtköpf am bestgeeigneten Ort, beispielsweise in einer Ecke eingebaut werden ohne den Sicherheitsraum zu verkleinern. Ausserdem arbeitet der Linearantrieb mit grossen Umschlingungswinkeln und ohne Querkräfte.The advantages achieved by the invention are essentially to be seen in the fact that the linear drive along the propellant space is attachable. The shaft head is particularly suitable for different arrangement variants and propellant or Trägmittelführungsvarianten. Depending on the power and mechanical dimensions, the linear drive can be installed in the shaft head in the most suitable location, for example in a corner, without reducing the safety space. In addition, the linear drive works with large wrap angles and no shear forces.

Das eine Ende des Riemens 11 ist an einem ersten Riemenfixpunkt 14 und das zweite Ende des Riemens 11 ist an einem zweiten Riemenfixpunkt 15 angeordnet. Der Riemen 11 ist über eine erste Umlenkrolle 16 über eine Profilrolle 17, über eine zweite Umlenkrollen 18, über eine dritte Umlenkrolle 19, über das Antriebsrad 13 und über eine vierte Umlenkrolle 20 geführt. Die erste Umlenkrolle 16, die zweite Umlenkrolle 18 und die Profilrolle 17 sind im Boden 21 der Aufzugskabine 3 integriert, wobei der Riemen in einem Bodenkanal 21.1 verläuft. Die Profilrolle 17 weist eine der Verzahnung des Riemens 11 entsprechende Verzahnung auf. Die erste Umlenkrolle 16 und die zweite Umlenkrolle 18 führen den Riemen 11 auf der nicht verzahnten Seite mittels stirnseitig angeordneten Flanschen. Die an der zweiten Führungsschiene 6 angeordnete dritte Umlenkrolle 19 steht mit ihrer Verzahnung im Eingriff mit der verzahnten Seite des Riemens 11 und weist eine Bremse für den Normalbetrieb auf. Das Antriebsrad 13 steht mit seiner Verzahnung im Eingriff mit der verzahnten Seite des Riemens 11. Ablenkrollen 22 des Linearantriebes 12 bewirken den Umschlingungswinkel des Riemens 11 am Antriebsrad 13. Das Antriebsrad 13 kann auch Ablenkrolle 22 sein. Nicht dargestellt- ist bzw. sind der Motor bzw. die Motoren für das Antriebsrad 13. Die vierte Umlenkrolle 20 ist im Gegengewicht angeordnet und im Aufbau vergleichbar mit der ersten Umlenkrolle 16 oder mit der zweiten Umlenkrolle 18.As support and propellant is at least one
Als Riemen 11 kann anstelle eines Zahnriemens ein Flachriemen oder ein Keilrippenriemen vorgesehen sein. Der mit Längsrippen versehene Keilrippenriemen weist gute Führungseigenschaften und eine erhöhte Traktionsfähigkeit auf. Solche flache Riemen enthalten Stahl- oder Synthetiklitzen von etwa 0,5 mm bis 3 mm. Es können auch zwei parallel geführte Riemen vorgesehen sein, wobei auch die Unlenkrollen bzw. die Ablenkrollen bzw. das Antriebsrad doppelt vorhanden sind. Unlenkrollen bzw. Ablenkrollen bzw. das Antriebsrad können im Durchmesser beispielsweise 50 mm gross oder grösser sein. Je Antriebsrad kann auch ein Motor vorhanden sein. Der Motor kann beispielsweise eine Asynchronmaschine oder eine Synchronmaschine mit oder ohne Permanentmagnete sein.As a

Die vorteilhaften Abmessungen bzw. das vorteilhafte Gewicht des mechanischen Linearantriebes erlauben einen lagemässig unabhängigen Einbau auch bei ungünstigen Platzverhältnissen. Die Eigenschaften von dünnen Riemen, die kleine Biegeradien zulassen, können somit voll ausgenutzt werden.The advantageous dimensions and the advantageous weight of the mechanical linear drive allow a positionally independent installation even in unfavorable space conditions. The properties of thin belts that allow small bending radii can thus be fully exploited.
