Description

Die Erfindung betrifft eine Bremsfangvorrichtung für Fördermittel, insbesondere Aufzugskabinen.The invention relates to a safety brake device for conveying means, in particular elevator cabins.

Bremsfangvorrichtungen haben die Aufgabe, ein Fördermittel bei einer zu hohen Geschwindigkeit stillzusetzen. Sie müssen in der Lage sein, das mit der Nutzlast beladene Fördermittel aus dem freien Fall anzuhalten, wobei für die zu erreichende Verzögerung ein Bereich festgesetzt ist.Brake safety devices have the task of a subsidy at a to shut down to high speed. You have to be able to do that To stop with the payload loaded funding from the free fall, wherein a range is set for the delay to be achieved.

Die meisten der bekannten Bremsfangvorrichtungen weisen Bremsbacken auf, die an einer in der Förderrichtung orientierten Schiene, beispielsweise einer Führungsschiene für eine Aufzugskabine, angreifen. Die Bewegung der Bremsbacken erfolgt bei den bekannten Bremsfangvorrichtungen durch Exzenter, Keile oder Wippen. DE 2 96 729U1 offenbart eine Bremsfangvorrichtung mit den Merkmale des Oberbegriffs des Anspruchs 1.Most of the known brake safety devices have brake shoes on, on a oriented in the conveying direction rail, for example a guide rail for an elevator car, attack. The movement the brake shoes takes place in the known brake safety devices by eccentric, Wedges or seesaws. DE 2 96 729U1 discloses a safety brake device with the features of the preamble of claim 1.

Die vorliegende Erfindung hat die Aufgabe, eine Bremsfangvorrichtung vorzuschlagen, die einfacher aufgebaut ist und kleinere Abmessungen hat als bekannte Bremsfangvorrichtungen mit vergleichbarer Bremswirkung.The present invention has the object, a safety brake device to propose, which is simpler and has smaller dimensions as known brake safety devices with comparable braking effect.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass die Bremsbacke auf einer Grundplatte befestigt ist, die mindestens annähernd rechtwinklig zum Förderweg relativ zum Tragelement bewegbar ist, dass gegenüber der Bremsbacke mindestens ein Einzughebel um eine in der Grundplatte gelagerten Achse schwenkbar und von einer Freigabestellung in eine Bremsstellung bewegbar ist, in der die Schiene zwischen dem freien Ende des Einzughebels und der Bremsbacke geklemmt wird, und dass auf dem Tragelement ein schwenkbarer Auslösehebel angeordnet ist, dessen freies Ende mit dem mindestens einen Einzughebel verbunden ist.This object is achieved according to the invention in that the Brake shoe is mounted on a base plate that is at least approximately perpendicular to the conveying path relative to the support element is movable, that opposite the brake shoe at least one feed lever to one in the base plate pivoted axle and from a release position in one Brake position is movable, in which the rail between the free end of the Retracting lever and the brake shoe is clamped, and that on the support element a pivotable release lever is arranged, the free end of the at least one Pull lever is connected.

Durch die Beweglichkeit der Grundplatte wird diese durch die beim Bremsvorgang auftretenden Kräfte automatisch so ausgerichtet, dass die rechtwinklig auf die Schiene wirkenden Anpresskräfte der Bremsbacke und des Einzughebels genau gleich sind.Due to the mobility of the base plate, this is due to the Braking process forces are automatically aligned so that the perpendicular to the rail acting pressing forces of the brake shoe and the Feed lever are exactly alike.

Nach einer bevorzugten Ausführungsart der Erfindung ist die Bremsbacke entgegen der Kraft von Federmitteln mindestens annähernd rechtwinklig zur Förderrichtung relativ zur Grundplatte bewegbar. Durch die Wahl und Vorspannung dieser Federmittel kann die Bremskraft vorbestimmt werden. Die gleiche Wirkung kann erzielt werden, wenn der mindestens eine Einzughebel durch eine auf sein freies Ende wirkende Kraft entgegen der Kraft von weiteren Federmitteln teleskopisch zusammendrückbar ist.According to a preferred embodiment of the invention, the brake shoe against the force of spring means at least approximately at right angles to the conveying direction relative to the base plate movable. By choice and bias This spring means, the braking force can be predetermined. The same effect can be achieved if the at least one feed lever by a force acting on its free end against the force of others Federmitteln is telescopically compressible.

Nach einer weiteren besonderen Ausführungsart ist an einem Bereich des freien Endes des mindestens einen Einzughebels eine Verzahnung so angeordnet, dass beim Auslösen der Bremsfangvorrichtung die Verzahnung zuerst die Schiene berührt und sich bei der weiteren Bewegung des Einzughebels in die Bremsstellung wieder von der Schiene entfernt, so dass in der Bremsstellung des Einzughebels eine der Verzahnung benachbarte Fläche des Einzughebels an der Schiene anliegt. Dadurch wird die Beanspruchung der Schiene reduziert.According to another particular embodiment is on an area the free end of the at least one feed lever a toothing so arranged that when triggering the brake device, the toothing First, the rail touches and the further movement of the feed lever in the braking position again away from the rail, so that in the Braking position of the feed lever one of the teeth adjacent surface of the Pulling lever abuts the rail. This will reduce the stress on the Rail reduced.

Vorzugsweise hält eine Rückstellfeder den Auslösehebel in einer Ruheposition, von der aus er in beiden Richtungen entgegen der Kraft der Rückstellfeder schwenkbar ist. Diese Lösung ist besonders einfach und kostengünstig.Preferably, a return spring holds the Release lever in a rest position, from which it counteracts in both directions the force of the return spring is pivotable. This solution is special easy and inexpensive.

Wenn nach einer anderen Ausführungsart der Erfindung auf der Achse zwei Einzughebel angeordnet sind, die zwischen sich einen Winkel einschliessen, kann die Bremsfangvorrichtung sowohl beim Abwärtsfahren als auch beim Aufwärtsfahren des Fördermittels wirksam sein. Wenn, wie oben erwähnt, einer der Einzughebel durch eine auf sein freies Ende wirkende Kraft entgegen der Kraft von weiteren Federmitteln teleskopisch zusammendrückbar ist, lassen sich für beide Fahrrichtungen unterschiedliche Bremskräfte realisieren. If according to another embodiment of the invention on the Axis two intake levers are arranged, which enclose an angle between them, The safety brake device can both downhill than also be effective when driving up the conveyor. If, as above mentioned, one of the feed lever by acting on its free end force telescopically compressible against the force of other spring means is, can be realized for both directions of travel different braking forces.

Wie die Figuren 1 und 2 zeigen, ist die Bremsfangvorrichtung auf einem Tragelement 1 aufgebaut, das mit einem durch die Bremsfangvorrichtung zu bremsenden Förderelement, beispielsweise einer Aufzugskabine, fest verbunden ist. Das Tragelement 1 ist in diesem Beispiel als eine auf zwei Seiten abgewinkelte Stahlplatte ausgebildet. Eine in Förderrichtung verlaufende, fest montierte Schiene 4 dient zum Bremsen der Aufzugskabine, indem Bremselemente daran angreifen, wie dies nachfolgend beschrieben wird. Auf dem Tragelement 1 ist eine Grundplatte 3 derart montiert, dass sie rechtwinklig zur Schiene 4 bewegbar ist. Dazu sind im Tragelement 1 vier Langlöcher 29 vorgesehen, durch welche Befestigungsschrauben 28 ragen, die in der Grundplatte 3 verankert sind. Die Grundplatte wird in der in den Figuren 1 und 2 dargestellten Ausgangsposition durch eine Zentrierfeder 12 gehalten, welche die Grundplatte 3 in den Figuren nach rechts gegen eine Stellschraube 13 drückt. Auf der Grundplatte 3 ist ein Tragklotz 8 befestigt, an dem eine gegen die Schiene 4 gerichtete Bremsbacke 5 mit einem Bremsbelag 6 über Tellerfedern 7 abgestützt ist. Der Bremsbacke gegenüberliegend sind auf der anderen Seite der Schiene 4 ein unterer Einzughebel 9 und ein oberer Einzughebel 10 an einer in der Grundplatte 3 gelagerten Achse 20 schwenkbar gelagert. As shown in Figures 1 and 2, the safety brake device is on one Support member 1 constructed, with a through the safety brake device to be braked conveyor element, such as an elevator car, firmly connected is. The support element 1 is in this example as one on two sides Angled steel plate formed. A running in the conveying direction, firmly mounted rail 4 serves to brake the elevator car by braking elements attack as described below. On the support element 1, a base plate 3 is mounted so as to be perpendicular to the Rail 4 is movable. For this purpose, four elongated holes 29 are provided in the support element 1, through which mounting screws 28 protrude, in the base plate. 3 are anchored. The base plate is in the illustrated in Figures 1 and 2 Starting position held by a centering spring 12, which is the base plate 3 in the figures to the right against a screw 13 presses. On the Base plate 3 is a support block 8 is fixed to the one against the rail. 4 directed brake shoe 5 with a brake pad 6 supported by disc springs 7 is. The brake shoe opposite are on the other side of the Rail 4, a lower feed lever 9 and an upper feed lever 10 at an in the base plate 3 mounted axle 20 pivotally mounted.

Ein Auslösehebel 11 ist mit einer Schraube 21 und einem Distanzstück 22 an einem Halteteil 2 schwenkbar befestigt, wobei das Halteteil 2 seinerseits mit dem Tragelement 1 verbunden ist. Eine Rückstellfeder 14 hält den Auslösehebel 11 in einer Ruheposition, von der aus er in beide Richtungen um die Schraube 21 schwenkbar ist. Die Auslösung des Bremsvorgangs erfolgt zum Beispiel durch eine Auslösevorrichtung, die ein parallel zur Bewegungsrichtung der Aufzugskabine bewegliches Zugmittel, beispielsweise ein Seil aufweist. Das Seil ist an den Enden des Weges der Aufzugskabine über Rollen geführt, von denen eine mit einer Einrichtung zur Überwachung der Geschwindigkeit und mit einer Bremsvorrichtung für das Seil ausgerüstet ist. Sobald die Einrichtung zur Überwachung der Geschwindigkeit feststellt, dass die Aufzugskabine eine vorbestimmte Grenzgeschwindigkeit überschreitet, wird die Bremsvorrichtung aktiviert und das genannte Seil steht sofort still. Die fortgesetzte Bewegung der Aufzugskabine bewirkt nun, dass der Auslösehebel 11 über ein mit dem Seil verbundenes Zugelement 15 aus seiner Ruheposition verschwenkt wird.A release lever 11 is provided with a screw 21 and a spacer 22 pivotally attached to a holding part 2, wherein the holding part 2 in turn is connected to the support element 1. A return spring 14 holds the Trigger lever 11 in a rest position, from which he is in both directions the screw 21 is pivotable. The triggering of the braking process takes place for example, by a triggering device, which is parallel to the direction of movement the elevator car has movable traction means, for example a rope. The rope is at the ends of the way of the elevator car over rollers one of which has a device for monitoring the speed and equipped with a brake device for the rope. As soon as the Device for monitoring the speed determines that the elevator car exceeds a predetermined limit speed, the braking device activated and the rope is immediately silent. The continued Movement of the elevator car now causes the release lever 11 via a pivoted with the rope tension element 15 pivoted from its rest position becomes.

Die Figuren 3a bis 3c zeigen im Detail, wie die Rückstellfeder 14 den Auslösehebel 11 aus beiden Schwenkrichtungen in die Ruheposition zurückbringt. Zwei fest mit dem Halteteil 2 verbundene Stehbolzen 19 nehmen zwischen sich einen Rückstellstab 24 auf, der an einem Ende mit einem Gewinde und am anderen Ende mit einem Kopf ausgestattet ist. Der Rückstellstab 24 nimmt, ausgehend von seinem in der Zeichnung unten liegenden Kopf, einen ersten Einsatz 25, die Rückstellfeder 14, einen zweiten Einsatz 25, einen mit dem Auslösehebel 11 fest verbundenen Übertragungsbolzen 26, eine Scheibe 23 und zwei gegeneinander verspannbare Muttern auf. Der Übertragungsbolzen 26 wird vom Rückstellstab 24 mit Spiel durchdrungen. Durch die Muttern kann der Rückstellfeder 14 eine Vorspannkraft verliehen werden, mit welcher sie die Stehbolzen 19 zwischen dem oberen Einsatz 25 und der Scheibe 23 klemmt und dadurch den Auslösehebel über den Übertragungsbolzen 26 in der in Figur 3a dargestellten Ruheposition hält. Wenn der Auslösehebel 11 aus der Ruheposition nach oben geschwenkt wird, wie in Figur 3b dargestellt, hebt der Übertragungsbolzen 26 den Rückstellstab 24 an und komprimiert über den unteren Einsatz 25 die Rückstellfeder 14. Wenn der Auslösehebel 11 aus der Ruheposition nach unten geschwenkt wird, wie in Figur 3c dargestellt, drückt er auf den oberen Einsatz 25 und komprimiert ebenfalls die Rückstellfeder 14. Somit ist auf konstruktiv einfache Weise sichergestellt, dass der Auslösehebel 11 durch die Kraft der Rückstellfeder 14 immer wieder in seine Ruheposition zurückgestellt wird.Figures 3a to 3c show in detail how the return spring 14 the Trigger lever 11 returns from both pivoting directions in the rest position. Two fixedly connected to the holding part 2 stud bolts 19 take between a reset rod 24, which at one end with a thread and equipped with a head at the other end. The reset rod 24 takes, starting from his lying in the drawing below head, one first insert 25, the return spring 14, a second insert 25, one with the trigger lever 11 fixedly connected transmission pin 26, a disc 23 and two mutually braced nuts on. The transmission bolt 26 is penetrated by the return rod 24 with play. Through the nuts the return spring 14 may be given a biasing force, with which they the stay bolts 19 between the upper insert 25 and the disc 23rd clamps and thereby the release lever on the transmission pin 26 in the 3a holding position shown in Figure 3a. When the trigger lever 11 from the Rest position is pivoted upward, as shown in Figure 3b, the lifts Transmission pin 26 to the return rod 24 and compressed over the lower Insert 25, the return spring 14. When the release lever 11 from the Rest position is pivoted downward, as shown in Figure 3c, he presses on the upper insert 25 and also compresses the return spring 14th Thus, it is ensured in a structurally simple manner that the release lever 11 by the force of the return spring 14 again in its rest position is reset.

Wenn beispielsweise die Bremsfangvorrichtung ausgelöst wird, während die Aufzugskabine nach unten fährt, wird der Auslösehebel in Figur 1 durch das Zugelement 15 nach oben ausgelenkt. Das gabelförmig ausgebildete freie Ende des Auslösehebels 11 bewegt den unteren Einzughebel 9 über einen an ihm angeordneten Bolzen 30 nach oben, wobei dieser Einzughebel 9 mit seiner Stirnseite mit der Schiene 4 in Kontakt kommt. Durch diesen Kontakt entsteht zwischen der Stirnseite des Einzughebels 9 und der Schiene 4 eine Reibkraft, die, weil die Aufzugskabine sich immer noch nach unten bewegt, den Einzughebel 9 weiter nach oben schwenkt. Eine Komponente der von der Schiene 4 auf den Einzughebel 9 ausgeübten Reaktionskraft schiebt nun über die Achse 20 die Grundplatte 3 gegen die Kraft der Zentrierfeder 12 nach links, so dass der Bremsbelag 6 der Bremsbacke 5 an der Schiene 4 zur Anlage kommt und die Schiene zwischen dem Einzughebel 9 und der Bremsbacke 5 eingeklemmt wird. Die maximale Bremskraft wird in der so genannten Fangstellung ausgeübt. Diese ist erreicht, wenn der Einzughebel 9 nahezu rechtwinklig zur Schiene 4 steht. Damit der Einzughebel 9 nicht über diese Fangstellung hinaus bewegt werden kann, was die Bremswirkung reduzieren würde, ist auf der Grundplatte 3 ein oberer Anschlag 18 angeordnet, an dem der synchron mit dem unteren Einzughebel 9 bewegte obere Einzughebel 10 anliegt.For example, when the safety brake device is released while the elevator car moves down, the release lever in Figure 1 deflected by the tension element 15 upwards. The fork-shaped free end of the trigger lever 11 moves the lower feed lever 9 via a arranged on it bolt 30 upwards, said feed lever 9 with its front side comes into contact with the rail 4. Through this contact arises between the end face of the feed lever 9 and the rail 4 a Frictional force, which, because the elevator car is still moving down, the Feed lever 9 continues to pivot upward. A component of the Rail 4 applied to the pull-in lever 9 reaction force now pushes over the axis 20, the base plate 3 against the force of the centering spring 12 to the left, so that the brake lining 6 of the brake shoe 5 on the rail 4 to the plant comes and the rail between the feed lever 9 and the brake shoe. 5 is trapped. The maximum braking force is in the so-called catch position exercised. This is achieved when the intake lever 9 almost at right angles to the rail 4 stands. So that the intake lever 9 does not have this catch position can be moved out, which would reduce the braking effect, is on the base plate 3, an upper stop 18 is arranged, on which the synchronous with the lower feed lever 9 moving upper feed lever 10 is present.

Die dargestellte Bremsfangvorrichtung wirkt auch, wenn die Aufzugskabine nach oben fährt. Bei einer Auslösung wird der Auslösehebel 11 nach unten verschwenkt, so dass der obere Einzughebel 10 an der Schiene 4 zur Anlage kommt. Wie man in Figur 1 sieht, kann der obere Einzughebel 10 durch Druck auf seine Stirnseite entgegen der Kraft eines Federpakets 31 um einen geringen Betrag teleskopisch verkürzt werden. In der Fangstellung, in welcher der untere Einzughebel 9 an einem unteren Anschlag 17 anliegt, wird folglich die Schiene 4 zwischen dem oberen Einzughebel 10 und der Bremsbacke geklemmt, wobei die Tellerfedern 7 der Bremsbacke 5 und das Federpaket 31 des oberen Einzughebels 10 eine Serieschaltung bilden. Das Resultat dieser Serieschaltung besteht darin, dass bei einer Bremsung der aufwärts fahrenden Aufzugskabine die Bremskraft geringer ist als bei einer Bremsung der abwärts fahrenden Aufzugskabine. Eine stirnseitig in den oberen Einzughebel 10 ragende Einstellschraube 32 erlaubt eine Feineinstellung der Bremskraft, indem durch Drehen dieser Einstellschraube 32 der Abstand der Stirnfläche des Einzughebels von seiner Schwenkachse fein verstellt wird.The illustrated brake catcher also acts when the elevator car goes up. When triggered, the trigger lever 11 pivoted downward, so that the upper feed lever 10 on the rail 4th comes to the plant. As can be seen in Figure 1, the upper feed lever 10th by pressure on its front side against the force of a spring assembly 31 um be shortened telescopically a small amount. In the catch position, in which the lower feed lever 9 abuts against a lower stop 17 is consequently the rail 4 between the upper feed lever 10 and the brake shoe clamped, wherein the disc springs 7 of the brake shoe 5 and the spring package 31 of the upper feed lever 10 form a series circuit. The result This series circuit is that when braking the upwards Elevator car, the braking force is lower than during braking of the downhill elevator car. One end in the upper intake lever 10 projecting adjusting screw 32 allows a fine adjustment of the braking force, by turning this adjustment screw 32, the distance of the end face of the Feeding lever is finely adjusted by its pivot axis.

Üblicherweise sind zwei Bremsfangvorrichtungen auf gegenüberliegenden Seiten einer Aufzugskabine montiert und so dimensioniert, dass in der Fangstellung die auf die Schienen ausgeübte Kraft genügt, um über die auftretende Reibung die voll beladene Kabine sicher zum Stehen zu bringen. Die beiden Bremsfangvorrichtungen werden durch eine mit der Achse 20 drehfest verbundene Verbindungswelle 16 synchronisiert.Usually, two brake safety devices are on opposite sides Sides of an elevator car mounted and dimensioned so that in the Catching force applied to the rails force is sufficient to over the occurring Friction to bring the fully loaded cab safely to a halt. The two Brake safety devices are connected by a rotationally fixed to the axis 20 Connecting shaft 16 synchronized.

Die Figuren 4a bis 4c zeigen in einem vergrösserten Ausschnitt aus der Figur 1 das freie Ende des unteren Einzughebels 9 und die Schiene 4. Bei einer Bremsung der nach unten fahrenden Aufzugskabine kommt ausgehend von der in Figur 4a dargestellten Grundstellung zuerst eine am oberen Ende der Stirnseite des Einzughebels vorgesehene Verzahnung 27 mit der Schiene 4 in Kontakt, wie dies in Figur 4b deutlich zu sehen ist. Die Verzahnung, die nicht über die ganze Breite des Einzughebels 9 verlaufen muss, ist gehärtet und es ist offensichtlich, dass durch die Verzahnung 27 die Reibung zwischen dem Einzughebel 9 und der Schiene 4 erhöht wird, so dass der Einzughebel 9 durch die entstehende Reibkraft sicher in seine Fangstellung bewegt wird. Da die Verzahnung 27 die Schiene beschädigen kann, ist am stirnseitigen Ende des Einzughebels 9 unterhalb der Verzahnung 27 ein Bereich ohne Verzahnung vorgesehen, welcher in der in Figur 4c dargestellten Fangstellung an der Schiene 4 anliegt. Somit ist bei einem Bremsvorgang die Verzahnung 27 nur während kurzer Zeit mit der Schiene 4 in Kontakt und kann diese folglich höchstens auf einem kurzen Stück beschädigen. Eine Verzahnung, wie sie hier anhand des unteren Einzughebels 9 beschrieben wurde, kann selbstverständlich auch am oberen Einzughebel 10 vorgesehen sein, wie dies in Figur 1 angedeutet ist. Figures 4a to 4c show in an enlarged section the figure 1, the free end of the lower feed lever 9 and the rail 4. Bei A braking of the downwardly moving elevator car comes from From the basic position shown in Figure 4a first one at the top of the Front side of the feed lever provided teeth 27 with the rail 4 in Contact, as can be clearly seen in Figure 4b. The gearing that is not must extend over the entire width of the feed lever 9 is cured and it it is obvious that by the teeth 27, the friction between the Feeding lever 9 and the rail 4 is increased, so that the feed lever 9 through the resulting frictional force is safely moved into its catch position. Because the Teeth 27 can damage the rail is at the front end of the Feed lever 9 below the teeth 27 an area without teeth provided, which in the fishing position shown in Figure 4c on the Rail 4 is applied. Thus, in a braking operation, the gearing 27 only for a short time with the rail 4 in contact and can therefore at most on a short piece damage. A gearing, like here has been described with reference to the lower feed lever 9, of course be provided on the upper feed lever 10, as indicated in Figure 1 is.

Schliesslich sei der Vollständigkeit halber noch erwähnt, dass mit der erfindungsgemässen Bremsvorrichtung nicht nur Aufzugskabinen, sondern beliebige Hebezeuge gesichert werden können.Finally, for the sake of completeness, it should be mentioned that with the Braking device according to the invention not only elevator cars, but arbitrary Hoists can be secured.
