Description
Die Erfindung betrifft einen Maschinenrahmen mit Gegenrollenträger für einen Aufzugsantrieb, wobei mit dem aus am Maschinenrahmen angeordneten Trägerelementen und Gegenrolle bestehenden Gegenrollenträger der erforderliche Seilstrangabstand zwischen einer Aufzugskabine und einem Gegengewicht machbar ist, und zum beidseitigen Tragen der Gegenrolle identische Trägerelemente vorgesehen sind, mittels welchen Trägerelementen unterschiedliche Seilstrangabstände machbar sind.The invention relates to a machine frame with counter-roller carrier for an elevator drive, which is feasible with the arranged on the machine frame carrier elements and counter-roller counter-roller carrier the required cable length between an elevator car and a counterweight, and for two-sided carrying the counter-roller identical support elements are provided by means of which carrier elements different Seilstrangabstände are feasible.
Aus der
Ein Nachteil der bekannten Einrichtung liegt darin, dass mit dem Gegenrollenträger und der Anordnung der Gegenrolle der Seilstrangabstand fest vorgegebenen ist. Für unterschiedliche Seilstrangabstände sind unterschiedliche Trägerelemente notwendig. Die Bohrlöcher müssen je nach Auftrag und Auslegung des Aufzuges gebohrt werden. Die Variantenvielfalt hat hohe Herstellungskosten zur Folge. Weiter nachteilig ist, dass der Gegenrollenanbau von unten im schwer zugänglichen Bereich der Betonfundamente vorgenommen werden muss.A disadvantage of the known device is that with the counter-roller carrier and the arrangement of the counter-roller of the cable strand spacing is fixed. Different carrier elements are necessary for different cable line spacings. The holes must be drilled according to the order and layout of the lift. The variant variety results in high production costs. Another disadvantage is that the Gegenrollenanbau must be made from below in the hard to reach area of the concrete foundations.
Aus der
Nachteilig bei dieser Verstellmöglichkeit der Gegenrolle ist die durch die Langschlitze vorgegebene undefinierte Lage der Gegenrolle je Lagerschild. Bei jeder Verstellung über die Langschlitze muss die Gegenrolle neu ausgerichtet werden.A disadvantage of this adjustment of the counter-roller is the predetermined by the long slots undefined position of the counter-roller per bearing plate. For each adjustment via the long slots, the counter roller must be realigned.
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 Maschinenrahmen zu schaffen, bei dem der Gegenrollenträger nach Wahl anbringbar ist.The invention aims to remedy this situation. The invention, as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a machine frame in which the counter-roller carrier can be attached at will.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass lediglich eine Variante von Trägerelementen notwendig ist. Mit dem Einheitsträgerelement können grössere und somit kostengünstigere Stückzahlen hergestellt werden. Mit dem erfindungsgemässen Trägerelement können unterschiedliche Seilstrangabstände realisiert werden. Auftragsabhängige Arbeiten entfallen dadurch. Ausserdem kann der Gegenrollenanbau gut zugänglich von oben ausgeführt werden. Die für die Sicherheit des Aufzuges wichtigen Befestigungsschrauben sind jederzeit kontrollierbar.The advantages achieved by the invention are to be seen essentially in the fact that only a variant of carrier elements is necessary. With the unit support element larger and thus more cost-effective quantities can be produced. With the support element according to the invention, different cable strand spacings can be realized. Job-dependent jobs are eliminated. In addition, the counter roller attachment can be easily accessed from above. The fastening screws important for the safety of the lift can be checked at any time.
