Description

Seilbremse an Geschwindigkeitsbegrenzer für AufzugeRope brake on speed limiter for lifts
Die Erfindung betrifft eine Seilbremse an einem Geschwmdig- keitsbegrenzer für Aufzuge, wobei die Seilbremse zwei Bremsbacken aufweist .The invention relates to a rope brake on a speed limiter for lifts, the rope brake having two brake shoes.
Derartige Seilbremsen werden beim Ueberschreiten einer zulassigen Geschwindigkeit vom Geschwindigkeitsbegrenzer betätigt, so dass ein über eine Seilscheibe des Geschwindigkeitsbegrenzers geführtes, mit einer Aufzugskabine fest verbundenes Begrenzerseil abgebremst und eine Fangvorrichtung ausgelost wird, mittels welcher die Aufzugskabine zum Stillstand gebracht wird.Such rope brakes are actuated by the speed limiter when an admissible speed is exceeded, so that a governor rope which is guided over a rope pulley of the speed limiter and is firmly connected to an elevator car is braked and a safety device is triggered, by means of which the elevator car is brought to a standstill.
Mit der Deutschen Patentschrift 25 28 067 ist ein Geschwindigkeitsbegrenzer mit einer Seilbremse bekannt geworden, die eine unbewegliche und eine bewegliche Bremsbacke aufweist. Die bewegliche Bremsbacke ist an einem in einem Seilbremsge- hause geführten Bügel befestigt. Zwei unter der Einwirkung je einer Druckfeder stehende Hebel sind emenends an zwei im Bügel gelagerten Bolzen angelenkt und anderenends an zwei im Seilbremsgehause gelagerten Achsen drehbar gelagert. Die Druckfedern sind je zwischen zwei Scheiben vorgespannt, wobei die eine Scheibe an einer Schulter des Hebels und die andere Scheibe an der Achse anliegt, und wobei in den Hebeln vorgesehene Langlocher eine Verschiebung der Hebel und damit auch der beweglichen Bremsbacke in Wirkungsrichtung der Druckfedern ermöglichen. Am Bügel ist ein Betatigungsblech vorgesehen, mittels welchem ein Betatigungsarm des Geschwindigkeitsbegrenzers die bewegliche Bremsbacke aus einer Offenstellung in eine Bremsstellung verschieben kann. Die Bremsbacken bestehen bei Seilbremsen der vorstehend beschriebenen Art meistens entweder aus Alubronze (CuAl) oder aus Spharoguss (GGG) . Mit Bremsbacken aus Alubronze wird eine gute Bremswirkung erreicht. Die durch die Bremsung freiwerdende Warme wird rasch abgeführt, jedoch ist der Verschleiss bei langen Bremswegen betrachtlich. Die Bremsbacken aus Spharoguss haben eine weniger gute Bremswirkung. Sie werden weniger verschlissen, können jedoch die Bremswarme schlechter abfuhren. Ausserdem muss mit Verschleiss am Begrenzerseil gerechnet werden.With the German patent specification 25 28 067 a speed limiter with a rope brake is known, which has an immovable and a movable brake shoe. The movable brake shoe is attached to a bracket that is guided in a cable brake housing. Two levers, each under the action of a compression spring, are articulated on two bolts mounted in the bracket and on the other rotatably mounted on two axles mounted in the cable brake housing. The compression springs are preloaded between two discs, one disc resting on a shoulder of the lever and the other disc on the axle, and elongated holes provided in the levers allow the levers and thus also the movable brake shoe to be displaced in the direction of action of the compression springs. An actuating plate is provided on the bracket, by means of which an actuating arm of the speed limiter can move the movable brake shoe from an open position to a braking position. In the case of rope brakes of the type described above, the brake shoes usually consist either of aluminum bronze (CuAl) or of cast iron (GGG). With aluminum brake shoes a good braking effect is achieved. The heat released by the braking is quickly dissipated, but the wear is considerable with long braking distances. The brake shoes made of cast iron have a less good braking effect. They are less worn out, but are less able to dissipate the brake heat. In addition, wear on the governor rope must be expected.
Der Erfindung liegt die Aufgabe zugrunde, eine Seilbremse gemass Oberbegriff vorzuschlagen, bei der vorstehend erwähnte Nachteile des Bremsbackenmaterials weniger zur Auswirkung kommen.The invention is based on the object of proposing a cable brake according to the preamble, in which the above-mentioned disadvantages of the brake shoe material have less of an effect.
Diese Aufgabe wird durch die in den unabhängigen Patentan- spruchen 1 und 4 angegebene Erfindung gelost.This object is achieved by the invention specified in independent patent claims 1 and 4.
In einer bevorzugten Ausfuhrung besteht die eine Bremsbacke aus Alubronze und die andere Bremsbacke aus Spharoguss oder Grauguss .In a preferred embodiment, one brake shoe is made of aluminum bronze and the other brake shoe is made of spargo cast iron or gray cast iron.
Besonders leistungsfähige Ausfuhrungen weisen ebenfalls zwei Bremsbacken aus unterschiedlichen Materialien auf, wobei jeweils eine der Bremsbacken aus einem keramikhaltigen Material besteht.Particularly powerful designs also have two brake shoes made of different materials, one of the brake shoes each made of a ceramic-containing material.
Bei einer weiteren Ausfuhrung bestehen beide Bremsbacken aus einem keramikhaltigen Material.In a further embodiment, both brake shoes are made of a ceramic-containing material.
Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass die gunstigen Eigenschaften beider Materialien ausgenutzt werden können. Beim Bremsen wird vor allem durch , die Bremsbacke aus Alubronze die Warme vom Begrenzerseil weggeführt, was sich positiv auf den Seilverschleiss auswirkt. Die Bremsbacke aus Spharoguss gewährleistet einen geringen Verschleiss. Die Vorteile der weiteren Ausfuhrung liegen in der hohen Verschleissfestigkeit und Warmebestan- digkeit des keramikhaltigen Materials.The advantages achieved with the invention can be seen in the fact that the favorable properties of both materials can be exploited. When braking , the aluminum bronze brake shoe guides the heat away from the governor rope, which has a positive effect on the rope wear. The brake shoe made of cast iron ensures low wear. The advantages of further execution lie in the high wear resistance and heat resistance of the ceramic-containing material.
Im folgenden wird die Erfindung anhand eines Ausfuhrungsbei- spieles im Zusammenhang mit der Zeichnung naher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment in connection with the drawing.

In den Fig. 1 bis 3 ist mit 1 ein Bremsgehäuse bezeichnet, dass aus zwei Seitenteilen 2,3 mit angebogenen Flanschen 2.1, 3.1 besteht. Die Seitenteile 2, 3 sind über ein1 to 3, 1 denotes a brake housing that consists of two side parts 2, 3 with flanges 2.1, 3.1 bent. The side parts 2, 3 are over a
Distanzstuck 4 und ein Distanzrohr 5 miteinander verbunden. Am Distanzstuck 4 ist eine unbewegliche Bremsbacke 6 befestigt, die beispielsweise aus Spharoguss (GGG) oder Grauguss besteht. Eine beispielsweise aus Alubronze (CuAl) bestehende bewegliche Bremsbacke 7 ist mit einem zwischen den Seitenteilen 2,3 des Bremsgehauses 1 geführten Fuhrungs- teil 8 verbunden.Spacer 4 and a spacer tube 5 connected to each other. An immovable brake shoe 6 is fastened to the spacer 4 and is made, for example, of Sparoguss (GGG) or gray cast iron. A movable brake shoe 7, for example made of aluminum bronze (CuAl), is connected to a guide part 8 guided between the side parts 2, 3 of the brake housing 1.
Zwei teleskopartige Hebel 9 bestehen aus je einem Zylinder- teil 9.1 und einem Kolbenteil 9.2. Die Zylinderteile 9.1 sind an zwei, am Fuhrungsteil 8 gelagerten Bolzen 10 angelenkt, wahrend die Kolbenteile 9.2 an zwei im Bremsge- hause 1 angeordneten Achsen 11 drehbar gelagert sind. Auf den Kolbenteilen 9.2 sind Druckfedern 12 angeordnet, die sich an den Enden über Scheiben 13 auf die Achsen 11 bzw. auf die Zylinderteile 9.1 abstutzen. Zwischen einer am Fuhrungsteil 8 befestigten Traverse 14 und einem am Bremsge- hause 1 angeordneten Winkel 15 ist eine Zugfeder 16 gespannt. Die Traverse 14 stutzt sich auf ein Betatigungsglied eines nicht dargestellten Geschwindigkeitsbegrenzers ab, so dass die an den teleskopartigen Hebeln 9 geführten Komponenten - Traverse 14, Fuhrungsteil 8 und Bremsbacke 7 - in einer oberen Stellung gehalten sind. Bei Ueberschreiten der zulässigen Geschwindigkeit einer Aufzugskabine wird das genannte Betätigungsglied so verschoben, dass es die Traverse 14 nicht mehr stutzt, so dass das Fuhrungsteil 8 mit der beweglichen Bremsbacke 7 nach unten fallt und die Bremsbacke 7 durch die Druckfedern 12 gegen ein zwischen ihr und der unbeweglichen Bremsbacke 6 laufen- des Begrenzerseil 17 gedruckt wird. Dadurch wird das Begrenzerseil 17 abgebremst und eine Fangvorrichtung ausgelost .Two telescopic levers 9 each consist of a cylinder part 9.1 and a piston part 9.2. The cylinder parts 9.1 are articulated on two bolts 10 mounted on the guide part 8, while the piston parts 9.2 are rotatably mounted on two axes 11 arranged in the brake housing 1. Compression springs 12 are arranged on the piston parts 9.2. lean on the cylinder parts 9.1. A tension spring 16 is tensioned between a cross member 14 fastened to the guide part 8 and an angle 15 arranged on the brake housing 1. The cross member 14 is supported on an actuating member of a speed limiter, not shown, so that the components guided on the telescopic levers 9 - cross member 14, guide part 8 and brake shoe 7 - are held in an upper position. If the permissible speed of an elevator car is exceeded, said actuator is moved so that it no longer supports the crossmember 14, so that the guide part 8 with the movable brake shoe 7 falls down and the brake shoe 7 against the one between it and the pressure springs 12 immobile brake shoe 6 running limiter rope 17 is printed. As a result, the governor rope 17 is braked and a safety gear is triggered.
Es ist auch möglich, für die unbewegliche Bremsbacke 6 Alubronze (CuAl) , und für die bewegliche Bremsbacke 7 Spharoguss (GGG) oder Grauguss (GG) zu verwenden. Auch kann anstelle der unterschiedlichen Metalle bzw. Legierungen für eine oder für beide Bremsbacken ein keramik- haltiges Material verwendet werden.It is also possible to use 6 aluminum bronze (CuAl) for the immobile brake shoe and 7 Sparoguss (GGG) or gray cast iron (GG) for the movable brake shoe. Instead of the different metals or alloys, a ceramic-containing material can be used for one or both brake shoes.
Es liegt im Rahmen der Erfindung, Bremsbacken gleichen Materials mit Bremsbelagen unterschiedlichen Materials auszustatten, wobei vorzugsweise die vorstehend genannten Materialien für die Bremsbelage verwendet werden.
