Description

Die Erfindung betrifft einen Aufzug mit einer an zwei, mit ihrer geraden Stirnverzahnung einander zugewendeten Schienen geführten und mittels eines mindestens eine Umlenkrolle umschliessenden Seiles mit einem Gegengewicht verbundenen Kabine, welche mit Bremseinrichtung, Motor und Getriebe zum Antrieb zweier, an der Kabine gelagerten, mit der Verzahnung der Schiene kämmenden Zahnrädern ausgestattet ist.The invention relates to an elevator with a guided on two rails with their straight end teeth facing each other and connected by means of at least one deflecting rope with a counterweight car, which with braking device, motor and gearbox for driving two, mounted on the car, with the Gearing of the rail meshing gears is equipped.

Bei einem bekannten Aufzug dieser Art (US-A-548 752) ist als Sicherheitseinrichtung lediglich eine von Hand zu bedienende Bremseinrichtung vorgesehen. Wie der Aufzug aus einer Nothaltstellung z.B. beim Ausfall des Motors in eine Stellung verholt werden kann, in der Fahrgäste den Aufzug verlassen können, wird nicht angegeben.In a known elevator of this type (US-A-548 752), only a manually operated braking device is provided as the safety device. Like the elevator from an emergency stop position e.g. if the motor fails, the vehicle can be moved into a position in which passengers can leave the elevator is not specified.

Bei anderen bekannten Aufzügen (FR-A-727 637, US-A- 4 051 923 und AU-A-442 061), bei denen der Antriebsmotor ebenfalls an der Kabine angeordnet ist, ist eine von ausserhalb des Aufzugschachtes bedienbare Hilfseinrichtung nicht vorgesehen.In other known elevators (FR-A-727 637, US-A-4 051 923 and AU-A-442 061), in which the drive motor is also arranged on the car, an auxiliary device which can be operated from outside the elevator shaft is not provided.

Die hier vorgesehenen Hilfseinrichtungen bedienen sich vielmehr der Antriebseinrichtung des Aufzugs, nur tritt anstelle des Elektromotors ein Handrad oder eine Handkurbel in der Kabine.The auxiliary devices provided here rather use the drive device of the elevator, only a handwheel or a hand crank occurs in the cabin instead of the electric motor.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Aufzug der eingangs genannten Art zu schaffen, bei dem parallel zur eigentlichen Antriebseinrichtung des Aufzugs eine Hilfseinrichtung vorgesehen, die von aussen bedienbar ist.The invention is therefore based on the object of creating an elevator of the type mentioned at the beginning, in which an auxiliary device is provided parallel to the actual drive device of the elevator and can be operated from the outside.

Diese Aufgabe wird dadurch gelöst, dass eine ausserhalb des Schachtes zu betätigende, die Umlenkrolle antreibende Hilfseinrichtung vorgesehen ist, mittels der die Kabine unabhängig von Motor und Getriebe, die an der Kabine angebracht sind, händisch nach oben und unten bewegbar ist.This object is achieved in that an auxiliary device to be actuated outside the shaft and driving the deflection roller is provided, by means of which the cabin can be moved up and down by hand independently of the engine and transmission which are attached to the cabin.

In den Unteransprüchen sind weitere Einzelheiten der Erfindung, die der zweckmässigen weiteren Ausbildung des Gegenstandes des Hauptanspruchs dienen, angegeben.In the subclaims further details of the invention are given, which serve the appropriate further development of the subject matter of the main claim.

In der Zeichnung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführungsform schematisch dargestellt. Die Fig. 1 und 2 zeigen einen Längs- und einen Querschnitt durch den Aufzugschacht und die Fig. 3 bis 5 eine von Hand betätigbare Hilfseinrichtung u.zw. Fig. 3 in Seitenansicht, Fig. 4 in Draufsicht und Fig. 5 eine Einzelheit im grösseren Massstab.In the drawing, the subject matter of the invention is shown schematically in an exemplary embodiment. 1 and 2 show a longitudinal and a cross section through the elevator shaft and FIGS. 3 to 5 a manually operated auxiliary device, etc. Fig. 3 in side view, Fig. 4 in plan view and Fig. 5 shows a detail on a larger scale.

Der Aufzugschacht 1 erstreckt sich über drei Geschosse 2, 3, 4 und ist oben mit einem Gerüst 5 versehen, das zwei Umlenkrollen 6 trägt, über die ein Seil 7 von der Kabine 8 zum Gegengewicht 9 verläuft. Dieses ist in Schienen 9a geführt. Das Gegengewicht entspricht vorzugsweise dem vollen Kabinengewicht und etwa 40% der Nutzlast. Es kann aber auch zweckmässig sein, das Gegengewicht etwas leichter als die Kabine auszubilden, so dass verhindert wird, dass die Kabine vom Gegengewicht nach oben gezogen wird.The elevator shaft 1 extends over three floors 2, 3, 4 and is provided at the top with a frame 5 which carries two deflection rollers 6, via which a rope 7 runs from the car 8 to the counterweight 9. This is guided in rails 9a. The counterweight preferably corresponds to the full cabin weight and approximately 40% of the payload. However, it can also be expedient to make the counterweight somewhat lighter than the cabin, so that the cabin is prevented from being pulled upward by the counterweight.

Die Kabine 8 ist an als Zahnstangen ausgebildeten Schienen 10 mit T-förmigem Querschnitt geführt, in die Zahnräder 11 eingreifen, welche am Dach der Kabine drehbar gelagert sind. Ferner befindet sich auf der Kabine ein Antriebsmotor 12 mit angeflanschtem Getriebe 13 und der vorgeschriebenen Bremse 14. Diese wirkt auf die Motorwelle 15, die sich beiderseits des Motors erstreckt und in Lager 16 gelagert ist. Über je ein Kegelradgetriebe 17 stehen die Zahnräder 11 in Antriebsverbindung mit dem Motor. Die Zahnräder 11 sind beiderseits mit Spurkränzen 18 versehen, so dass sich eine sichere Führung quer zu der, durch die Zahnstangenlängsachsen bestimmten Schachtlängsmittelebene ergibt. Die Kabine weist jedoch keine Führungen auf, die in Richtungen, welche in der Schachtlängsmittelebene liegen, wirksam sind. Dadurch kann die Kabine in diesen Richtungen ausweichen, bis sie sich im seitlichen Gleichgewicht befindet, was dann der Fall ist, wenn der Zahndruck zwischen den Zahnrädern und den Zahnstangen an beiden Schienen gleich gross ist. So kommt es bei ungleicher Belastung, ungleicher Abnützung u.dgl. zu einer kleinen seitlichen Verschiebung der Kabine und dadurch zu gleich grossen Zahndrükken. Durch den stets gleich grossen Zahndruck der in Eingriff stehenden Zähne kommt es zu einer gleichmässigen Abnützung der beiden Zahnräder bzw. Zahnstangen, so dass sich die höchstmögliche Lebensdauer dieser Teile ergibt. Um ein Kippen der Kabine oder Schwingen quer zur Ebene, in der die beiden Schienen liegen, zu verhindern, sind weitere Spurkranzräder 19 unterhalb der Kabine vorgesehen. Diese Führungsrollen können Zahnräder sein, analog den Antriebszahnrädern 11.The cabin 8 is guided on rails 10 which are designed as toothed racks and have a T-shaped cross section, into which gear wheels 11 engage, which are rotatably mounted on the roof of the cabin. There is also a drive motor 12 with a flanged gear 13 and the prescribed brake 14 on the cabin. This acts on the motor shaft 15, which extends on both sides of the motor and is mounted in bearings 16. Via a bevel gear 17, the gears 11 are in drive connection with the motor. The gearwheels 11 are provided on both sides with wheel flanges 18, so that there is reliable guidance transverse to the longitudinal axis of the shaft longitudinal axis defined by the longitudinal axes of the rack. However, the cabin has no guides which are effective in directions which lie in the longitudinal center plane of the shaft. This allows the cabin to move in these directions until it is in lateral equilibrium, which is the case when the tooth pressure between the gears and the racks is the same on both rails. So it happens with uneven load, uneven wear and the like. to a small lateral shift of the cabin and thus to tooth gears of the same size. Due to the tooth pressure of the meshing teeth, which is always the same, the two gears or racks are evenly worn, so that the longest possible service life of these parts results. In order to prevent the cabin from tipping or swinging transversely to the plane in which the two rails lie, further flanged wheels 19 are provided below the cabin. These guide rollers can be gearwheels, analogous to the drive gearwheels 11.

An der Kabine ist ferner ein Geschwindigkeitsregler 20 vorgesehen, der auf die Motorwelle 15 einwirkt. Dieser Regler kann aber auch im Boden der Kabine 8 vorgesehen sein, und er kann mit den Zahnrädern 19 zusammenwirken, so dass sich eine grössere Sicherheit ergibt, weil die Kabine durch voneinander unabhängigen Zahnrädern 11 und 19 gehalten werden kann.A speed controller 20, which acts on the motor shaft 15, is also provided on the cabin. However, this controller can also be provided in the floor of the cabin 8, and it can interact with the gear wheels 19, so that there is greater security because the cabin can be held by gear wheels 11 and 19 which are independent of one another.

Die Steuerung 21 des Aufzuges befindet sich am Kabinendach und ist voll elektronisch. Es kann ein nicht dargestelltes Notstromaggregat, z.B. eine Batterie, im Gebäude vorgesehen sein, die es gestattet, die Kabine auf die nächstliegende Haltestelle zu senken. Hiebei kann eine ausserhalb des Schachtes vorgesehene Kontrollmöglichkeit vorgesehen werden. Eine andere oder weitere Hilfseinrichtung kann in der Form vorgesehen sein, dass in der Kabine ein Notrufbetätigungsknopf vorgesehen wird, der die Bremse lüftet und das Senken der Kabine in die nächste Haltestelle gestattet.The controller 21 of the elevator is located on the cabin roof and is fully electronic. An emergency generator, not shown, e.g. a battery can be provided in the building, which allows the cabin to be lowered to the nearest stop. A control option provided outside the shaft can be provided here. Another or further auxiliary device can be provided in the form that an emergency call button is provided in the cabin, which releases the brake and allows the cabin to be lowered into the next stop.

Der Geschwindigkeitsregler wird vorzugsweise so eingestellt, dass bei Erreichen der 1,4-fachen Kabinengeschwindigkeit ein Bremslüfter eine auf der Motorwelle sitzende Bremsscheibe blockiert. Diese Blockierung soll von der Kabine aus nicht aufgehoben werden können. Vielmehr soll der Geschwindigkeitsregler erst durch Fachkräfte bedient werden können, damit die Kabine in die nächste Haltestelle gesenkt werden kann. Die Bremse des Geschwindigkeitsreglers 20 ist so ausgelegt, dass sie auch bei Seilriss eine Bewegung der Kabine unmöglich macht.The speed controller is preferably set so that when the 1.4 times the cabin speed is reached, a brake fan blocks a brake disc seated on the motor shaft. This blockage should not be able to be removed from the cabin. Rather, the speed controller should only be operated by specialists so that the cabin in the next stop can be lowered. The brake of the speed controller 20 is designed in such a way that it makes movement of the cabin impossible even if the cable breaks.

Die üblichen und notwendigen Steuereinrichtungen und Installationen zur Betätigung der Schachttüren und Kabinentüren sind nicht dargestellt, weil sie nicht Gegenstand der Erfindung sind. Ebenso ist das Schleppkabel nicht eingezeichnet, über das die Kabine mit Strom versorgt wird.The usual and necessary control devices and installations for actuating the shaft doors and cabin doors are not shown because they are not the subject of the invention. Likewise, the trailing cable, via which the cabin is supplied with electricity, is not shown.

Bei den üblichen mit Maschinenräumen versehenen Aufzügen kann die Aufzugskabine bei Ausfall des öffentlichen Stromnetzes von Hand gesenkt oder nach oben bewegt werden. Zu diesem Zweck genügt es, mittels eines Handrades oder einer Handkurbel das vom Aufzugsseil umschlungene Treibrad in Drehung zu versetzen, nachdem die Magnetbremse von Hand gelüftet worden ist. Bei dem erfindungsgemässen Aufzug muss ebenfalls eine Hilfseinrichtung vorgesehen sein, mittels der bei Netzausfall die Kabine in das nächstgelegene Stockwerk angehoben oder gesenkt werden kann.In the case of the usual machine room-equipped elevators, the elevator car can be lowered by hand or moved upwards in the event of a power grid failure. For this purpose, it is sufficient to use a handwheel or a hand crank to set the drive wheel wrapped in the elevator rope in rotation after the magnetic brake has been released by hand. In the elevator according to the invention, an auxiliary device must also be provided, by means of which the car can be raised or lowered to the nearest floor in the event of a power failure.

Solche Hilfseinrichtungen können sowohl von der Kabine als auch vom Gebäude aus betätigbar sein. Es können diese beiden Gattungen der Hilfseinrichtung gleichzeitig vorgesehen werden.Such auxiliary devices can be operated both from the cabin and from the building. These two types of auxiliary device can be provided simultaneously.

Gemäss den Fig. 3 bis 5 ist die eine Umlenkrolle 6 zu einer üblichen Treibscheibe für das die Kabine mit dem Gegengewicht verbindenen Seil 7 ausgebildet und sitzt auf einer Welle 31, welche im Traggerüst 5 und in einem an der Schachtmauer angebrachten Lager drehbar gelagert ist. Auf dieser Welle sitzt ein Kettenzahnrad 32, das von einer Treibkette 33 umschlungen ist, welche eine Verbindung mit einem Kettenrad 34 herstellt, das fliegend in einem nicht dargestellten Lager gelagert ist, welches sich in der Mauerung des Schachtes 1 befindet. Dieses Kettenrad 34 ist mit einem Kegelrad 35 starr verbunden. Ein zweites Kegelrad 36 ist axial verschiebbar gelagert und kann in Eingriff mit dem Kegelrad 35 gebracht werden. Die weiteren Teile der Hilfseinrichtung sind in Fig. 5 im grösseren Massstab dargestellt. Das Kegelrad 36 sitzt auf einer Welle 37, die mit einem Bund 38 versehen und in den Schildern 39, 40 verschiebbar und drehbar gelagert ist. Zwischen dem Schild 39 und dem Bund 38 ist eine Druckfeder 41 vorgesehen, welche im entspannten Zustand die Welle 37 und das Kegelrad 36 in der dargestellten Lage hält.According to FIGS. 3 to 5, the one deflecting roller 6 is formed into a conventional traction sheave for the rope 7 connecting the cabin to the counterweight and is seated on a shaft 31 which is rotatably mounted in the supporting frame 5 and in a bearing attached to the shaft wall. On this shaft sits a sprocket 32, which is wrapped in a drive chain 33, which creates a connection with a sprocket 34, which is overhung in a bearing, not shown, which is located in the wall of the shaft 1. This sprocket 34 is rigidly connected to a bevel gear 35. A second bevel gear 36 is axially displaceably mounted and can be brought into engagement with the bevel gear 35. The other parts of the auxiliary device are shown in Fig. 5 on a larger scale. The bevel gear 36 is seated on a shaft 37 which is provided with a collar 38 and is displaceably and rotatably mounted in the plates 39, 40. Between the shield 39 and the collar 38, a compression spring 41 is provided, which holds the shaft 37 and the bevel gear 36 in the position shown in the relaxed state.

Das Lagerschild 40 befindet sich in einer Mauernische 42, die mittels eines Deckels 43 verschlossen ist. Das sich in der Mauernische 42 befindliche Ende der Welle 37 ist mit einem Mehrkant 44 versehen, auf den ein strichpunktiert dargestelltes Handrad 45 aufsteckbar ist. Die Nabe 46 dieses Handrades 45 ist mit einem Bund 47 versehen, der mit dem Taster eines Schalters 48 in der Mauernische 42 zusammenwirkt.The end shield 40 is located in a wall recess 42 which is closed by a cover 43. The end of the shaft 37 located in the wall recess 42 is provided with a polygon 44, onto which a handwheel 45 shown in dash-dotted lines can be attached. The hub 46 of this handwheel 45 is provided with a collar 47 which interacts with the button of a switch 48 in the wall recess 42.

Wird der Deckel 43 von der Mauernische 42 entfernt, kann das Handrad 45 auf das Ende 44 der Welle 37 aufgeschoben werden, wobei die Einstecktiefe so gewählt ist, dass mittels des Handrades 45 die Welle 37 entgegen der Kraft der Feder 41 verschoben werden kann und die Kegelräder 35 und 36 in Eingriff kommen. Dabei legt sich der Flansch 47 an den Taster des Schalters 48 an, der dabei den am Kabinendach befindlichen Bremsmagnet an eine Hilfsbatterie anlegt, so dass die Bremse gelüftet ist. Nunmehr hängt die Kabine am Seil 7 und kann durch Drehen des Handrades 45 gehoben oder gesenkt werden, weil die Drehbewegung des Handrades über das Kegelgetriebe 35, 36 auf das Kettengetriebe 32, 33, 34 und mittels der Welle 31 auf die als Treibscheibe ausgebildete Umlenkrolle 6 übertragen wird. Überwiegt das Gewicht der Kabine gegenüber dem Gegengewicht 9, so wird die Kabine in das nächste Stockwerk gesenkt. Ist die Kabine leer, so dass das Gegengewicht schwerer ist, so wird die Kabine in das nächst höhere Stockwerk gehoben.If the cover 43 is removed from the wall recess 42, the handwheel 45 can be pushed onto the end 44 of the shaft 37, the insertion depth being selected so that the shaft 37 can be displaced against the force of the spring 41 by means of the handwheel 45 and the Bevel gears 35 and 36 come into engagement. The flange 47 bears against the button of the switch 48, which in this case applies the brake magnet located on the cabin roof to an auxiliary battery, so that the brake is released. Now the cabin hangs on the rope 7 and can be raised or lowered by turning the handwheel 45 because the rotary movement of the handwheel via the bevel gear 35, 36 to the chain gear 32, 33, 34 and by means of the shaft 31 to the deflection roller 6 designed as a traction sheave is transmitted. If the weight of the cabin outweighs the counterweight 9, the cabin is lowered to the next floor. If the cabin is empty so that the counterweight is heavier, the cabin is raised to the next higher floor.

In Fig. 3 ist die Einrichtung im höchsten Stockwerk dargestellt. Der Kettenantrieb 33 kann jedoch verlängert sein, so dass die in Fig. 5 gezeigte Einrichtung in einem tiefer liegenden Stockwerk angeordnet sein kann.In Fig. 3 the device on the top floor is shown. The chain drive 33 can, however, be extended so that the device shown in FIG. 5 can be arranged on a lower floor.

Soll die Hilfseinrichtung in der Kabine angeordnet sein, so entspricht ihre Ausbildung weitgehend der bekannten Hilfseinrichtung in Aufzugsmaschinenräumen. Der Unterschied besteht nur darin, dass diese Hilfseinrichtung nicht auf ein Treibrad für das Seil, sondern auf die Zahnräder 11 wirkt. Es können beide Hilfseinrichtungen gleichzeitig vorgesehen sein.If the auxiliary device is to be arranged in the cabin, its design largely corresponds to the known auxiliary device in elevator machine rooms. The only difference is that this auxiliary device does not act on a drive wheel for the rope, but on the gear wheels 11. Both auxiliary devices can be provided at the same time.

Die beschriebene Hilfseinrichtung ist nur in einer prinzipiellen Ausführungsform veranschaulicht. Selbstverständlich können an Stelle eines Kettengetriebes Kardanwellen vorgesehen sein und ebenso kann an Stelle des Handrades eine Handkurbel Verwendung finden. Wesentlich ist, dass eine Lüftung der Bremse nur dann möglich ist, wenn zwischen dem Betätigungsorgan 45 und dem Aufzugsseil 7 eine wirksame Antriebsverbindung besteht. Sollte diese unterbrochen werden, so muss auch die Magnetbremse einfallen und die Lage der Kabine sichern.The auxiliary device described is only illustrated in a basic embodiment. Of course, cardan shafts can be provided instead of a chain transmission and a hand crank can also be used instead of the handwheel. It is essential that the brake can only be released if there is an effective drive connection between the actuating member 45 and the elevator rope 7. If this is interrupted, the magnetic brake must also apply and secure the position of the cabin.
