Description

Die Erfindung betrifft einen maschinenhauslosen Aufzug, bei dem die mittels eines Verbindungsseiles mit einem Gegengewicht verbundene Kabine od.dgl. mit einem Triebwerk versehen ist, das mindestens ein mit einem ruhenden Bauteil des Aufzuges zusammenwirkendes Reibrad antreibt.The invention relates to a machine house-less elevator, in which the cabin or the like connected by means of a connecting cable to a counterweight. is provided with an engine that drives at least one friction wheel interacting with a stationary component of the elevator.

Durch die DE-OS 35 23 187 ist ein Aufzug bekannt geworden, der aus einer in Führungen eines Gebäude­schachtes auf- und abbeweglichen Aufzugskabine besteht, die über ein über Umlenkrollen an der Oberseite des Schachtes verlaufendes Seil mit einem oder mehreren Ge­gengewichten verbunden ist. Der Aufzug ist dadurch ge­kennzeichnet, daß der Antrieb der Aufzugskabine über einen an der Kabine angebrachten Reibradantrieb erfolgt, der aus mindestens zwei, vier oder mehreren, auf eine oder zwei im Schacht längsverlaufende Führungsschienen einwirkenden Reibrädern besteht.From DE-OS 35 23 187 an elevator has become known which consists of an elevator car which can move up and down in the guides of a building shaft and which is connected to one or more counterweights by means of a rope running over deflection rollers at the top of the shaft. The elevator is characterized in that the elevator car is driven by a friction wheel drive attached to the cabin, which consists of at least two, four or more friction wheels acting on one or two longitudinal guide rails in the shaft.

Die Erfindung bezweckt die Schaffung von Sicher­heitseinrichtungen für solche reibradgetriebene Aufzüge.The invention aims to provide safety devices for such friction wheel driven elevators.

Die Erfindung bezieht sich demnach auf einen maschinenhauslosen Aufzug, bei dem die mittels eines Verbindungsseiles mit einem Gegegewicht verbundene Kabine od. dgl. mit einem Triebwerk versehen ist, das mindestens ein mit einem ruhenden Bauteil des Aufzuges zusammen­wirkendes Reibrad antreibt und ist dadurch charakteri­siert, daß die Kabine wenigstens eine Fangvorrichtung und eine Steuereinrichtung aufweist und die Umlenkrolle für das Verbindungsseil oder bei Anordnung mehrerer Um­ lenkrollen eine von diesen mit einer zusätzlichen Brems- bzw. Fangvorrichtung verbunden ist.The invention therefore relates to a machine house-less elevator, in which the cabin or the like connected by means of a connecting cable to a counterweight is provided with an engine which drives at least one friction wheel interacting with a stationary component of the elevator and is characterized in that Cabin has at least one safety device and a control device and the deflection roller for the connecting cable or when arranging several Um Steer rollers one of these is connected to an additional braking or safety device.

Die Erfindung bezieht sich ferner auf Ausgestal­tungen dieser Grundidee.The invention further relates to refinements of this basic idea.

In der Zeichnung ist der Gegenstand der Erfindung in zwei beispielsweisen Ausführungsformen schematisch dargestellt. Es zeigen die Fig. 1 und 2 einen Längs- und einen Querschnitt durch einen Aufzugsschacht und die Fig. 3 und 4 Schnitte längs und quer zum Aufzugs­schacht im Bereich des Antriebes.In the drawing, the subject matter of the invention is shown schematically in two exemplary embodiments. 1 and 2 show a longitudinal and a cross section through an elevator shaft and FIGS. 3 and 4 sections along and across the elevator shaft in the area of the drive.

Der Aufzugsschacht 1 erstreckt sich gemäß Fig. 1 über drei Geschoße 2,3,4 und ist oben mit einem Gerüst 5 versehen, das zwei Umlenkrollen 6,6′ trägt, über die ein Verbindungsseil 7 von dem als Kabine ausgebildeten Fördergerät 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, wodurch verhindert wird, daß die Kabine vom Gegengewicht nach oben gezogen wird.The elevator shaft 1 extends according to FIG. 1 over three floors 2,3,4 and is provided at the top with a scaffold 5, which carries two deflection rollers 6,6 ', via which a connecting cable 7 from the conveyor 8 designed as a car to the counterweight 9 runs. 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, which prevents the cabin from being pulled upward by the counterweight.

Die Kabine 8 ist an Schienen 10 mit T-förmigem Querschnitt geführt, die in Führungsrollen 11 eingreifen. Diese sind am Dach der Kabine drehbar gelagert. 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 Reibräder 21 in Antriebsverbindung mit dem Motor 12. Sie sitzen auf Wellen 22, die von den Kegelradgetrie­ben 17 ausgehen. Jedes Reibrad 21 ist mit einem elasti­schen Stoff überzogen, der einen hohen Reibwert hat. Mit diesem Überzug rollen die Räder 21 auf einer Gegenbahn 23 ab, die von einem Vorsprung im Mauerwerk 24 des Schach­tes 1 gebildet wird. An seiner Stirnseite ist ein rauher Belag 25 aufgebracht, um den Reibwert zu erhöhen. Dieser Belag kann aus Beton oder einem Mörtel bestehen. Es können aber auch rauhe Metallstreifen, vor allem mit strukturierter Oberfläche, Verwendung finden. Zufolge der Eigenelastizität des Überzuges der Reibräder 21 ist es nicht erforderlich, diese Räder selbst elastisch zu lagern.The cabin 8 is guided on rails 10 with a T-shaped cross section, which engage in guide rollers 11. These 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. The friction wheels 21 are in driving connection with the motor 12 via a bevel gear 17 each. They are seated on shafts 22 which emanate from the bevel gear 17. Each friction wheel 21 is covered with an elastic material that has a high coefficient of friction. With this coating, the wheels 21 roll on a counter track 23, which is formed by a projection in the masonry 24 of the shaft 1. A rough covering 25 is applied to its end face in order to increase the coefficient of friction. This The covering can be made of concrete or a mortar. Rough metal strips, especially with a textured surface, can also be used. Due to the inherent elasticity of the coating of the friction wheels 21, it is not necessary to support these wheels themselves elastically.

Die Kabine ist mittels der Räder 11 und deren Spur­kränzen 18 in der Richtung quer zu der durch die Schie­nen 10 gegebenen Mittelebene geführt. Die Reibräder 21 sorgen für eine Führung der Kabine parallel zu dieser Mittelebene.The cabin is guided by means of the wheels 11 and their flanges 18 in the direction transverse to the median plane given by the rails 10. The friction wheels 21 ensure that the cabin is guided parallel to this central plane.

An der Kabine ist ferner ein Geschwindigkeitsreg­ler 20 vorgesehen, der auf die Motorwelle 15 einwirkt. Die Steuerung 26 des Aufzuges befindet sich ebenfalls 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.A speed controller 20, which acts on the motor shaft 15, is also provided on the cabin. The control 26 of the elevator is also 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 to 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 can be lowered to the next stop. The brake of the speed controller 20 is designed so that it makes movement of the cabin impossible even in the event of a cable break.

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 operating 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 elevators with machine rooms, 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.

Eine solche Hilfseinrichtung ist in der am 1. März 1984 veröffentlichten internationalen Anmeldung PCT/AT82/00023 (Internationale Veröffentlichungsnummer WO 84/00743) beschrieben.Such an auxiliary device is described in the international application PCT / AT82 / 00023 (international publication number WO 84/00743) published on March 1, 1984.

Es können auch die Führungsschienen 10 als Gegen­bahn benützt werden. Eine solche Ausführungsform ist in den Fig. 3 und 4 dargestellt. An der Wand 24 des Auf­zugsschachtes ist die Führungsschiene 10 befestigt. Ihr Steg 27 greift in einen Ausschnitt 28 des Kabinen­daches 8′ ein. Auf diesem Dach befindet sich der Antriebs­motor 12, der über die Motorwelle 15 ein Reibrad 29 an­treibt, das in einer Konsole 30 gelagert ist. In Bezug auf die Schiene 10 gegenüberliegend ist eine Druckrol­le 31 vorgesehen, die in einem Schwinghebel 32 drehbar gelagert ist. Dieser ist schwenkbar in einer Konsole 33 gelagert. Die Achse 34 der Druckrolle 31 steht auf der einen Seite des Schwinghebels 32 vor. An diesem vor­springenden Teil der Achse 34 ist eine Zugfeder 35 ein­gehängt, die mit ihrem anderen Ende bei 36 verankert ist. Der Schwinghebel 32 ist nur schwach geneigt, so daß die Anpreßkraft der Druckrolle an den Steg 27 ein Vielfaches der Kraft der Feder 35 ist.The guide rails 10 can also be used as a counter track. Such an embodiment is shown in FIGS. 3 and 4. The guide rail 10 is fastened to the wall 24 of the elevator shaft. Your web 27 engages in a cutout 28 of the canopy 8 '. On this roof is the drive motor 12, which drives a friction wheel 29 via the motor shaft 15, which is mounted in a bracket 30. In relation to the rail 10 opposite a pressure roller 31 is provided which is rotatably mounted in a rocker arm 32. This is pivotally mounted in a bracket 33. The axis 34 of the pressure roller 31 is on the one side of the rocker arm 32 in front. On this projecting part of the axis 34, a tension spring 35 is suspended, which is anchored at 36 at its other end. The rocker arm 32 is only slightly inclined so that the pressure force of the pressure roller on the web 27 is a multiple of the force of the spring 35.

Die Anordnung kann jedoch auch so getroffen werden, daß der Schwinghebel 32 durch einen Schwenkhebel 37 ersetzt ist, der in der Fig. 3 strichpunktiert einge­zeichnet ist. Er ist an der Konsole 30 schwenkbar ge­lagert, der Schwinghebel 32 und die Konsole 33 entfallen sodann. Die Wirkung der Feder 35 ist jedoch die gleiche.However, the arrangement can also be made in such a way that the rocker arm 32 is replaced by a rocker arm 37, which is shown in broken lines in FIG. 3. It is pivotally mounted on the console 30, the rocker arm 32 and the console 33 are then omitted. However, the action of the spring 35 is the same.

Zur Erhöhung der Sicherheit kann die Umlenkrolle 6 mit einer Brems- und/oder Fangvorrichtung verbunden sein. In diesem Falle läuft das Verbindungsseil in einer Keilrille der Umlenkrolle 6, so daß ein Gleiten des Seiles 7 in Bezug auf die Rolle 6 vermieden wird. Um den Umschlingungswinkel des Verbindungsseiles 7 zu erhöhen, kann die Umlenkrolle 6′ tiefer gesetzt werden. Eine andere Methode, den vollen Umschlingungswinkel auszunützen, besteht darin, daß die Umlenkrollen 6,6′ durch ein Zahnkettengetriebe miteinander verbunden sind, das das Übersetzungsverhältnis 1 : 1 aufweist. Zur weiteren Vergrößerung des Umschlingungswinkels kann zwischen den Umlenkrollen 6 und 6′ und oberhalb derselben eine weitere Umlenkrolle vorgesehen sein (nicht dargestellt), deren Abstand von den Umlenkrollen 6,6′ so gewählt ist, daß das Verbindungsseil 7 nach einer Wellenlinie ver­läuft. Auch diese weitere Umlenkrolle mit Keilrille kann in das Kettengetriebe einbezogen werden.To increase security, the deflection roller 6 can be connected to a braking and / or safety device. In this case, the connecting cable runs in a wedge groove of the deflection roller 6, so that sliding of the cable 7 with respect to the roller 6 is avoided. In order to increase the wrap angle of the connecting cable 7, the guide roller 6 'can be set lower. Another method of utilizing the full wrap angle is that the deflection rollers 6, 6 'are connected to one another by a toothed chain gear, which has a transmission ratio of 1: 1. To further increase the wrap angle, a further deflection roller can be provided between the deflection rollers 6 and 6 'and above the latter (not shown), the distance from the deflection rollers 6,6' is selected such that the connecting cable 7 runs along a wavy line. This additional pulley with V-groove can also be included in the chain gear.

Um die Gefahr einer unzulässigen Herabsetzung des Reibungswertes zwischen Reibrad und Gegenbahn zu verhindern, können den Reibrädern Waschenrichtungen zugeordnet werden, welche mit Hilfe chemischer Substanzen bei der Bewegung des Fördergerätes die Umfangsfläche der Reibräder bzw. die Oberfläche der Gegenbahn von fettigen oder seifigen Substanzen säubern.In order to prevent the risk of an inadmissible reduction in the friction value between the friction wheel and the counter track, the friction wheels can be assigned washing directions which, with the aid of chemical substances, move the peripheral surface of the friction wheels or the surface of the counter track from when the conveyor is moving Clean greasy or soapy substances.

Um eine zwischen den einzelnen Überprüfungen der Aufzugsanlage auftretende unzulässige Abnützung der Reibräder oder der Gegenbahn zu verhindern oder zumindest anzuzeigen, können entsprechende Maßnahmen getroffen werden. Eine davon ist, daß der Schwinghebel 32 mit einem am Kabinendach 8′ feststehenden Kontakt zusammenwirkt. Bei zunehmender Abnützung der Reibräder bzw. der Druck­rolle 31 wird der Schwinghebel 32 nach unten ver­schwenkt und nähert sich unter der Wirkung der Feder 35 immer mehr dem Kabinendach 8′. Bei Erreichung einer Grenzlage wird der nicht dargestellte oben erwähnte Kontakt wirksam und die Anlage stillgesetzt.Appropriate measures can be taken to prevent or at least indicate an inadmissible wear of the friction wheels or the opposing path that occurs between the individual checks of the elevator system. One of them is that the rocker arm 32 cooperates with a fixed contact on the canopy 8 '. With increasing wear of the friction wheels or the pressure roller 31, the rocker arm 32 is pivoted downwards and approaches the canopy 8 'under the action of the spring 35 more and more. When a limit position is reached, the above-mentioned contact becomes effective and the system is shut down.

Die Überzüge der Reibräder können aus mehreren Schichten bestehen, von denen die äußere Verschleiß­schichte eine andere Farbe aufweist als die weiter innen angeordneten Schichten. Die Abnützung der Verschleiß­schichte kann aus der verbliebenen Dicke des farbigen Ringes, den die Verschleißschichte in Stirnansicht bildet, abgeschätzt werden.The coatings of the friction wheels can consist of several layers, of which the outer wear layer has a different color than the layers arranged further inside. The wear of the wear layer can be estimated from the remaining thickness of the colored ring that the wear layer forms in the end view.

Der Antrieb und die Steuerung der Kabine kann natürlich auch unterhalb des Fördergerätes an dessen Boden angebracht sein, was z.B. dann erforderlich ist, wenn das Fördergerät aus einer Plattform oder einem Korb besteht.The drive and control of the cabin can of course also be attached below the conveyor on the floor, which e.g. is required if the conveyor consists of a platform or a basket.

Die Erfindung ist nicht auf die dargestellten und bisher beschriebenen Ausführungsformen beschränkt. So ist es nicht erforderlich, daß ein Aufzugsschacht vor­gesehen ist. Es kann auch ein Gerüst verwendet werden, wie dies vor allem bei Bauaufzügen der Fall ist. Die Erfindung ist auch auf eine Anlage anwendbar, bei der eine einzige tragende Säule vorgesehen ist, an der das Fördergerät geführt wird.The invention is not limited to the illustrated and previously described embodiments. So it is not necessary that an elevator shaft is provided. Scaffolding can also be used, as is especially the case with construction lifts. The invention is also applicable to a system in which a single supporting column is provided, on which the conveyor is guided.

Die Druckrolle 31 kann durch ein Reibrad ersetzt werden, das z.B. über eine Kardanwelle angetrieben wird, so daß es die Schwenkbewegung des Schwinghebels 32 mitmachen kann.The pressure roller 31 can be replaced by a friction wheel which is driven, for example, via a cardan shaft, so that it pivots the rocking lever 32 can participate.

Die Erfindung kann auch nachträglich bei bestehenden Aufzugsanlagen verwendet werden. Wird eine Einrichtung gemäß den Fig. 3 und 4 benutzt, so sind keinerlei baulidne Änderungen im Aufzugsschacht erforderlich, das vorhandene Maschinenhaus kann abgetragen werden. Es genügen die Umlenkrollen 6,6′. Die Schienen 10 werden als erfindungs­gemäße Gegenbahnen für die Reibräder 29 verwendet. Der Antrieb und die Scherheitseinrichtungen können jederzeit am Fördergerät angebracht werden. Das bei der Erfindung erforderliche Schleppkabel zur Versorgung des Antriebs­motors 12 mit elektrischem Strom sowie die Steuerungs­kabel sind in der Zeichnung nicht dargestellt.The invention can also be used retrospectively in existing elevator systems. If a device according to FIGS. 3 and 4 is used, no structural changes in the elevator shaft are required, the existing machine house can be removed. The deflection rollers 6.6 'are sufficient. The rails 10 are used as counter-tracks according to the invention for the friction wheels 29. The drive and the safety devices can be attached to the conveyor at any time. The trailing cable required in the invention for supplying the drive motor 12 with electrical current and the control cables are not shown in the drawing.
