Description

Die Erfindung betrifft eine getriebelose Antriebsmaschine eines Aufzuges bestehend aus einem Motor, einer von einer Motorwelle getragenen Treibscheibe, über die Seile zum Tragen und Bewegen einer Aufzugskabine und eines Gegengewichtes geführt sind, einer an einem Lagerbock angeordneten Bremseinrichtung zum Stillsetzen des Motors und einer Betätigungseinrichtung für den Notbetrieb, mittels der der Motor manuell betätigbar ist.The invention relates to a gearless drive machine a lift consisting of a motor, one of a kind Motor shaft carried traction sheave, over the ropes to Carrying and moving an elevator car and a Counterweight are led, one at a bearing block arranged braking device for stopping the engine and an actuating device for emergency operation, by means of which the engine is manually operated.

Eine getriebelose Antriebsmaschine einer Aufzuges ist z.B. aus US-A-4 355 785 bekannt.A gearless drive machine of a lift is e.g. from US-A-4,355,785.

Aus der Schrift EP 0 706 968 A2 ist eine Antriebseinheit für einen Aufzug bekannt geworden. Die Antriebseinheit weist eine durchgehende Welle auf, die sowohl die Motorwelle wie auch die Getriebewelle bildet. Am einen Ende der Welle ist ein Getriebe mit einer Treibscheibe für die Aufzugsseile angeordnet. Am motorseitigen freien Ende der Welle ist zur Notbetätigung der Antriebseinheit ein Handrad aufgesetzt. An einer Grundplatte sind Bremsbacken tragende Hebel gelenkig angeordnet. Die Bremsbacken werden mittels eines Zylinders gegen den Aussenumfang eines Bremskörpers gedrückt.The document EP 0 706 968 A2 discloses a drive unit become known for a lift. The drive unit has a continuous wave, both the Motor shaft as well as the transmission shaft forms. At one end The shaft is a transmission with a traction sheave for the Elevator cables arranged. At the engine-side free end of the Shaft is a handwheel for emergency operation of the drive unit placed. On a base plate brake shoes are bearing Lever articulated. The brake shoes are using a cylinder against the outer circumference of a brake body pressed.

Ein Nachteil der bekannten Einrichtung liegt darin, dass das Handrad Nahe am Motor angeordnet ist. Beim Betätigen des Handrades können Finger vom drehenden Handrad leicht erfasst und eingeklemmt werden. Bei Notbetätigung muss die Bremse gelöst und gleichzeitig das Handrad betätigt werden. Das Lösen der Bremse ist erschwert, weil die Bremsanordnung auf der einen Seite und das Handrad auf der anderen Seite des Motors angeordnet sind.A disadvantage of the known device is that the handwheel is located close to the engine. When pressed of the handwheel can easily move fingers from the rotating handwheel be caught and pinched. For emergency operation, the Brake released while the handwheel is pressed. The release of the brake is difficult because the brake assembly on one side and the hand wheel on the other side of the engine are arranged.

Bei getriebelosen Antriebsmaschinen müssen bei Notbetätigung wesentlich grössere Kräfte überwunden werden. Üblicherweise wird dazu ein Getriebe mit Handrad verwendet, wobei das Getriebe mittels einer Kupplungseinrichtung mit der Hauptwelle verbunden ist. Solche Einrichtungen sind teuer, umständlich und nicht ganz ungefährlich in der Handhabung.For gearless drive machines must be at Emergency operation significantly greater forces are overcome. Usually, a gear with handwheel is used to wherein the transmission by means of a coupling device with the main shaft is connected. Such facilities are expensive, cumbersome and not completely safe in the Handling.

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 Handantrieb mit einem Handrad zu schaffen, mittels dem eine Notbetätigung des Aufzuges problemlos und sicher ist.The invention aims to remedy this situation. The invention, as characterized in claim 1 solves the task to avoid the disadvantages of the known device and to provide a manual drive with a handwheel, by means of an emergency operation of the elevator easily and safely is.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der Handantrieb einfach und werkzeuglos montierbar ist. Der Handantrieb kann bei Bedarf auf die Antriebsmaschine aufgesteckt werden. Eine Kupplung, wie dies bei einem festmontierten Handantrieb notwendig ist, entfällt. Die Sicherheit der den Notbetrieb vornehmenden Personen ist in jedem Fall gewährleistet, weil beim Aufstecken des Handantriebes der elektrische Antrieb automatisch ausgeschaltet wird. Ausserdem genügt bei einer Aufzugseinrichtung mit mehreren Aufzügen ein Handantrieb, der jeweils beim notzubetätigenden Aufzug einsetzbar ist.The advantages achieved by the invention are in essential to see that the manual drive easy and can be mounted without tools. The manual drive can at Need to be plugged onto the prime mover. A Clutch, as with a fixed hand drive is necessary, not applicable. The safety of the emergency operation persons in any case is guaranteed, because when plugging in the manual drive of the electric drive is automatically turned off. Moreover, it is enough for one Elevator device with several elevators, a manual drive, which can be used in each case when notzubetätigen elevator.
