Definitions
- the present invention relates to a tripping device for a speed limiter of an elevator installation and to a speed limiter equipped with such a tripping device.
- the prior art discloses (prescribed) speed limiters for elevator installations which, when a triggering speed is exceeded, provide emergency measures, e.g. activate the safety gear.
- the DE 34 46 337 A1 shows a speed limiter for an elevator system that triggers the safety gear of the car when a tripping speed is exceeded.
- the speed limiter has a pulley which is connected to the car by means of a cable loop and is set in rotation of the car in rotation.
- the pulley carries flyweights, which are connected to rotatably mounted eccentric cams. As the pulley rotates, the centrifugal weights move outwardly, causing the eccentric cams to rotate or deflect so that they overshoot a braking wheel when the firing speed is exceeded to press. As a result, the sheave and by means of the driving ability of its rope groove, the rope wrapped around it is braked, whereby the safety gear is triggered.
- a comparable speed limiter is in the DE 18 00 270 A1 discloses in which a pulley is driven by two pivotally mounted on journal flyweights of a control cable.
- the flyweight are each equipped at their outwardly pivoting ends with a leaf spring, which in turn has a brake shoe. This arrangement rotates within a stationary brake wheel. Exceeds the rotational speed of the sheave a predetermined threshold, the flyweights pivot about the pins that the respective brake shoe moves outward and presses against the brake wheel, so that the pulley is braked so that the control cable of the car can not follow and a safety gear triggers.
- speed limiters are known in which instead of a brake wheel, a trigger wheel is provided, which is acted upon by the coupling means when the release speed is exceeded and taken in the direction of rotation. By the rotation of the trigger wheel then a rope brake for the cable pulley looping around rope is triggered, which in turn a safety gear is triggered on the car.
- a speed limiter is marketed for example under the name OL 100 by Wittur or is in the DE 2007 052 280 A1 disclosed.
- the speed limiters known in the prior art have the disadvantage that the interaction of pulley, flyweight, coupling means and tripping or braking a variety of individual components conditionally, which are all subject to certain tolerance requirements.
- the previous solutions require high manufacturing accuracy, since they are constructively overdetermined. This over-determination of the construction can lead to disturbances and high wear.
- the overall system is relatively expensive as a result, since certain minimum tolerances must be maintained for the individual elements during manufacture. This is also due to the symmetrical structure, ie some elements such as flyweights and coupling means are usually provided at least twice, so that both the tolerances of an element and element-overlapping tolerances play a role.
- the present invention therefore proposes a release device for a speed limiter of an elevator installation according to claim 1.
- Advantageous embodiments are the subject of the dependent claims and the following description.
- the invention teaches to provide an elastic material between the coupling means and the trigger wheel. Due to the elasticity of size deviations of components can be compensated among each other and tolerance overruns. As a result, the tolerance requirements on the individual components decrease, so that the manufacturing costs can be reduced.
- the release wheel can be divided across its width into two functional areas. A clamping area, which comes into contact with the coupling means, and a triggering area, which abuts the release lever.
- a (rubber) elastic material in particular as a covering, is now provided.
- the rigidity is reduced and also increases the static friction, whereby even smaller normal forces are sufficient for triggering.
- the material is a spring component, which softens with increasing lining thickness.
- the material expediently has a high stiction in contact with the coupling means and a high elastic deformability.
- the shear strength and the quality of the connection to the body should be sufficient to transmit the release torque.
- a high time stability should also be present under the given environmental influences.
- the rubber-like properties also create a damping effect when triggered, which contributes to material protection, especially at high speeds.
- the response can be improved and the reliability of the response can be increased.
- the elasticity and the friction of the material can be selected so that a rotation of the trigger wheel takes place safely as soon as a predetermined loading of the trigger wheel takes place by the coupling means.
- the ratio of elasticity and friction can be specified so that a tolerance compensation of component sizes and a safe triggering of the trigger wheel are possible.
- the tripping wheel in turn can actuate a release lever for triggering a cable brake and / or a switch for de-energized switching of the elevator drive.
- the trigger wheel on a tire or covering of the elastic material.
- the material can be easily provided between the trigger wheel and coupling means and, for example, in the case of wear also replaced.
- the coupling means may be provided with the elastic material.
- the flyweight simultaneously represent the coupling means.
- at least two additional components and their connection means can be saved with each other.
- the design of the tripping device becomes simpler and cheaper.
- the design is kinematically and statically determined, which increases the tolerance ranges to be complied with.
- the coupling agents acting as flyweight compounds expediently have a coupling region for loading or contacting the trigger wheel and a weight range.
- the weight range is expediently designed so that it does not come into contact with the trigger wheel and that it is suitable for receiving separate additional weights. These separate additional weights are used to set the release speed of the release device.
- edge of the coupling means at least partially in the form of an Archimedean spiral, gently applying the trigger wheel without jerk occurs with moderate increase in force.
- the correspondingly shaped edge of the coupling means is expediently in the area designated above as a coupling region.
- the provision of an elastic material can develop particular advantages, since the acting as flyweight coupling means depending on the release speed may possibly have different shapes, so that the distance of the edge of the coupling means from the trigger wheel, if necessary, depends on the design of the limiter , These different distances can be compensated for while maintaining all other structural sizes by the elastic material.
- the coupling means have a nose which defines an end stop, an excessive loading of the trigger wheel by the coupling means can be avoided.
- the tripping wheel is at rest.
- the coupling means rotate around the trigger wheel at the speed of the governor wheel, being deflected about its own axis depending on the speed of rotation of the governor wheel.
- the coupling means are expediently so arranged that the rotation or deflection about its own axis when applied to the trigger wheel leads to a self-boosting of the admission. This self-energizing continues until the trigger wheel has reached the rotational speed of the governor wheel.
- these are expediently equipped with an end stop. If this strikes against the trigger wheel, no further screwing can take place.
- the flyweights are coupled to each other by means of a cable connection and tensioned spring loaded, so that there is a linear relationship between the spring load and the deflection of the flyweight.
- the flyweights are arranged in pairs on the governor wheel and connected by a cable connection to compensate for gravitational effects. Furthermore, they are biased against the centrifugal force so that sufficient for an actuation of the trigger wheel deflection of the flyweight takes place only when reaching the triggering speed.
- the flyweight and the spring are dimensioned so that below the release speed no deflection of the flyweight takes place. In this way, the components mentioned during normal operation remain at rest, so that no wear takes place.

- An inventive speed limiter for an elevator is equipped with a tripping device according to the invention for triggering a cable brake and / or for actuating a switch for stopping an elevator drive.
- An advantageous cable brake comprises a four-link coupling gear, in particular a sliding crank.
- a large leverage can be generated, so that a large braking force, which, for example, from a cocked Spring can be provided, can be held by a small release force. This small release force is absorbed by the trigger wheel.
- the rope brake comprises an eccentric crank, in particular, the eccentricity is greater than the crank length.
- the joint connecting the crank and the connecting rod presses on the trigger wheel via a release lever.
- the trigger is held in a metastable state on the trigger wheel.
- the joint is thereby pushed through, so that the rope brake is released.
- Triggers the triggering device the trigger wheel is set in rotation, thereby pushing the release lever away.
- the joint can move, so that the connecting rod can move up and the rope brake closes.
- a screw arrangement may be provided, in which, for example, by means of a screw or nut to be screwed, a transmission element located behind it, such as, for example, a washer, clamps the spring (plate spring, spiral spring, etc.).
- the Beipporrad be equipped on both sides. Flywheels with a trigger wheel for releasing the rope brake are seated on one side, whereas flywheels and a trigger wheel for actuating an electrical switch are arranged on the other side.
- the two-sided design can be different Triggering speeds for the rope brake and the electrical switch are provided and adjusted.
- the parameters required by standard elevator standards "release speed” (mechanical emergency stop) and "pre-switch-off speed” (electrical emergency stop) can thereby be set independently of one another.
- FIGS. 1 to 3 the same elements are provided with the same reference numerals.
- the FIGS. 1 and 2 are described in a coherent and comprehensive way.

- the flyweights 105a, 105b each have a coupling region 106a, 106b and a nose 107a, 107b defining a stop. Furthermore, the fly weights 105a, 105b have attachable and removable additional weights 108a, 108b to set the release speed of the triggering device 100.
- the flyweight / coupling means 105a, 105b are connected by means of a cable connection 200, which is biased by a spring 201.
- a predetermined centrifugal force must be achieved to overcome the spring biasing force.
- the spring biasing force is expediently predetermined so that the flyweights / coupling means 105a, 105b remain at rest during normal operation and are not deflected. This wear and disturbing noises, especially rattles can be avoided.

Description
Die vorliegende Erfindung betrifft eine Auslösevorrichtung für einen Geschwindigkeitsbegrenzer einer Aufzugsanlage sowie einen mit einer solchen Auslösevorrichtung ausgestatteten Geschwindigkeitsbegrenzer.The present invention relates to a tripping device for a speed limiter of an elevator installation and to a speed limiter equipped with such a tripping device.
Aus dem Stand der Technik sind (vorgeschriebene) Geschwindigkeitsbegrenzer für Aufzugsanlagen bekannt, welche bei Überschreiten einer Auslösegeschwindigkeit Notfallmaßnahmen, z.B. das Aktivieren der Fangvorrichtung, einleiten.The prior art discloses (prescribed) speed limiters for elevator installations which, when a triggering speed is exceeded, provide emergency measures, e.g. activate the safety gear.
Die
Ein vergleichbarer Geschwindigkeitsbegrenzer ist in der
Weiterhin sind Geschwindigkeitsbegrenzer bekannt, bei denen statt einem Bremsrad ein Auslöserad vorgesehen ist, das bei Überschreiten der Auslösegeschwindigkeit von den Koppelmitteln beaufschlagt und in Drehrichtung mitgenommen wird. Durch die Drehung des Auslöserads wird dann eine Seilbremse für das die Seilscheibe umschlingende Seil ausgelöst, wodurch wiederum eine Fangvorrichtung am Fahrkorb ausgelöst wird. Ein solcher Geschwindigkeitsbegrenzer wird beispielsweise unter der Bezeichnung OL 100 von der Firma Wittur vertrieben oder ist in der
Die im Stand der Technik bekannten Geschwindigkeitsbegrenzer weisen den Nachteil auf, dass das Zusammenwirken von Seilscheibe, Fliehmassen, Koppelmitteln und Auslöse- bzw. Bremsrad eine Vielzahl von Einzelkomponenten bedingt, welche alle bestimmten Toleranzanforderungen unterliegen. Die bisherigen Lösungen setzen hohe Fertigungsgenauigkeiten voraus, da sie konstruktiv überbestimmt sind. Diese Überbestimmtheit der Konstruktion kann zu Störungen und hohem Verschleiß führen. Das Gesamtsystem ist in der Folge relativ teuer, da bei der Herstellung gewisse Mindesttoleranzen für die Einzelelemente eingehalten werden müssen. Dies liegt auch am symmetrischen Aufbau, d.h. einige Elemente wie z.B. Fliehmassen und Koppelmittel sind in der Regel mindestens doppelt vorgesehen, so dass sowohl die Toleranzen eines Elements als auch elementübergreifende Toleranzen eine Rolle spielen. In der Folge gestaltet sich insbesondere die Herstellung und Wartung schwierig, da nicht nur Bauteile ausgesucht werden müssen, die innerhalb der vorgeschriebenen Toleranzgrenzen liegen, sondern deren Abmessungen auch untereinander zusammenpassen. Da bei einem Aufzug üblicherweise große Kräfte und Geschwindigkeiten auftreten, sind die einzelnen Elemente aus steifen und festen Materialien, wie z.B. Stahl, gefertigt, welche eine sehr große Federkonstante haben, so dass die zulässigen Toleranzen relativ klein ausfallen. Durch die großen Federkonstanten wirken große Kräfte, so dass die Elemente, Lager und Bolzen massiv ausgebildet sind..The speed limiters known in the prior art have the disadvantage that the interaction of pulley, flyweight, coupling means and tripping or braking a variety of individual components conditionally, which are all subject to certain tolerance requirements. The previous solutions require high manufacturing accuracy, since they are constructively overdetermined. This over-determination of the construction can lead to disturbances and high wear. The overall system is relatively expensive as a result, since certain minimum tolerances must be maintained for the individual elements during manufacture. This is also due to the symmetrical structure, ie some elements such as flyweights and coupling means are usually provided at least twice, so that both the tolerances of an element and element-overlapping tolerances play a role. As a result, in particular the production and maintenance is difficult because not only components must be selected within the prescribed tolerance limits, but their dimensions also fit together. Since large forces and speeds usually occur in an elevator, the individual elements are made of rigid and solid materials, such as steel, which have a very large spring constant, so that the permissible tolerances are relatively small. Due to the large spring constants act large forces, so that the elements, bearings and bolts are solid ..
Es ist somit wünschenswert, eine Auslösevorrichtung für einen Geschwindigkeitsbegrenzer anzugeben, die einfacher und damit kostengünstiger herzustellen ist, wobei das Auslöseverhalten jedoch nicht verschlechtert sein darf.It is thus desirable to provide a trigger device for a speed limiter, which is simpler and thus cheaper to produce, but the tripping behavior must not be deteriorated.
Ausgehend von diesem Stand der Technik schlägt die vorliegende Erfindung daher eine Auslösevorrichtung für einen Geschwindigkeitsbegrenzer einer Aufzugsanlage gemäß dem Patentanspruch 1 vor. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung.Based on this prior art, the present invention therefore proposes a release device for a speed limiter of an elevator installation according to claim 1. Advantageous embodiments are the subject of the dependent claims and the following description.
Die Erfindung lehrt insbesondere, ein elastisches Material zwischen den Koppelmitteln und dem Auslöserad vorzusehen. Durch die Elastizität können Größenabweichungen von Bauteilen untereinander sowie Toleranzüberschreitungen ausgeglichen werden. In der Folge sinken die Toleranzanforderungen an die einzelnen Bauteile, so dass die Herstellungskosten reduziert werden können.In particular, the invention teaches to provide an elastic material between the coupling means and the trigger wheel. Due to the elasticity of size deviations of components can be compensated among each other and tolerance overruns. As a result, the tolerance requirements on the individual components decrease, so that the manufacturing costs can be reduced.
Auch die im Stand der Technik vorhandene hohe Steifigkeit des Klemmmechanismus, welche zu großen Normalkräften sowie zu engen Toleranzfeldern führt, wird vermindert. Das Auslöserad kann über seine Breite in zwei Funktionsbereiche unterteilt werden. Einen Klemmbereich, der in Kontakt mit den Koppelmitteln tritt, und einen Auslösebereich, an dem der Auslösehebel anliegt. Zumindest im Klemmbereich wird nun ein (gummi-)elastisches Material, insbesondere als Belag, vorgesehen. Dadurch wird die Steifigkeit vermindert und auch die Haftreibung erhöht, wodurch bereits kleinere Normalkräfte zur Auslösung ausreichend sind. Gleichzeitig stellt das Material eine Federkomponente dar, die mit zunehmender Belagdicke weicher wird.The existing in the prior art high rigidity of the clamping mechanism, which leads to large normal forces and tight tolerance fields is reduced. The release wheel can be divided across its width into two functional areas. A clamping area, which comes into contact with the coupling means, and a triggering area, which abuts the release lever. At least in the clamping area, a (rubber) elastic material, in particular as a covering, is now provided. As a result, the rigidity is reduced and also increases the static friction, whereby even smaller normal forces are sufficient for triggering. At the same time, the material is a spring component, which softens with increasing lining thickness.
Der Werkstoff weist zweckmäßigerweise eine hohe Haftreibung im Kontakt mit den Koppelmitteln sowie eine hohe elastische Verformbarkeit auf. Gleichzeitig sollte die Scherfestigkeit und die Qualität der Verbindung zum Grundkörper ausreichend sein, um das Auslösemoment zu übertragen. Außerdem sollte eine hohe Zeitfestigkeit auch unter den gegebenen Umwelteinflüssen vorhanden sein. Durch die gummiähnlichen Eigenschaften entsteht zusätzlich bei der Auslösung ein Dämpfungseffekt, der vor allem bei hohen Geschwindigkeiten zur Materialschonung beiträgt.The material expediently has a high stiction in contact with the coupling means and a high elastic deformability. At the same time, the shear strength and the quality of the connection to the body should be sufficient to transmit the release torque. In addition, a high time stability should also be present under the given environmental influences. The rubber-like properties also create a damping effect when triggered, which contributes to material protection, especially at high speeds.
Wird ein elastisches Material eingesetzt, welches zugleich eine reibungsvermittelnde Wirkung zeigt, kann das Ansprechverhalten verbessert und die Zuverlässigkeit des Ansprechens erhöht werden. Die Elastizität sowie die Reibung des Materials können so gewählt werden, dass eine Rotation des Auslöserads sicher erfolgt, sobald eine vorgegebene Beaufschlagung des Auslöserads durch die Koppelmittel stattfindet. Das Verhältnis von Elastizität und Reibung kann so vorgegeben werden, dass ein Toleranzausgleich von Bauteilgrößen und ein sicheres Auslösen des Auslöserads möglich sind. Das Auslöserad wiederum kann einen Auslösehebel zum Auslösen einer Seilbremse und/oder einen Schalter zum stromlos Schalten des Aufzugantriebs betätigen.If an elastic material is used, which also has a friction-promoting effect, the response can be improved and the reliability of the response can be increased. The elasticity and the friction of the material can be selected so that a rotation of the trigger wheel takes place safely as soon as a predetermined loading of the trigger wheel takes place by the coupling means. The ratio of elasticity and friction can be specified so that a tolerance compensation of component sizes and a safe triggering of the trigger wheel are possible. The tripping wheel in turn can actuate a release lever for triggering a cable brake and / or a switch for de-energized switching of the elevator drive.
Es wurde erkannt, dass wider Erwarten auch im Aufzugsbau, wo raue Umgebungsbedingungen im Schacht vorliegen und große Kräfte wirken, elastisches Material bewusst eingesetzt werden kann, um bestimmte Vorteile zu erreichen. Als elastisches Material mit geeigneten Eigenschaften kann beispielsweise Vulkollan eingesetzt werden. Ebenso können andere Kunststoffe auf Elastomerbasis verwendet werden.It has been recognized that contrary to expectations, even in elevator construction, where harsh environmental conditions prevail in the shaft and large forces act, elastic material can be deliberately used to achieve certain advantages. As an elastic material with suitable properties Vulkollan can be used for example. Likewise, other elastomers based plastics can be used.
Vorteilhafterweise weist das Auslöserad einen Reifen bzw. Belag aus dem elastischen Material auf. Auf diese Weise kann das Material einfach zwischen Auslöserad und Koppelmittel bereitgestellt und beispielsweise im Falle von Verschleiß auch ausgetauscht werden. Alternativ oder zusätzlich können auch die Koppelmittel mit dem elastischen Material versehen sein.Advantageously, the trigger wheel on a tire or covering of the elastic material. In this way, the material can be easily provided between the trigger wheel and coupling means and, for example, in the case of wear also replaced. Alternatively or additionally, the coupling means may be provided with the elastic material.
Gemäß einer besonders bevorzugten Ausgestaltung stellen die Fliehmassen gleichzeitig die Koppelmittel dar. Bei dieser bevorzugten Lösung können somit wenigstens zwei zusätzliche Bauteile sowie deren Verbindungsmittel untereinander eingespart werden. Die Konstruktion der Auslösevorrichtung wird einfacher und preiswerter. Die Konstruktion ist kinematisch und statisch bestimmt, was die einzuhaltenden Toleranzbereiche vergrößert. Die als Fliehmassen wirkenden Koppelmittel (bzw. die als Koppelmittel wirkenden Fliehmassen) weisen zweckmäßigerweise einen Koppelbereich zur Beaufschlagung bzw. Kontaktierung des Auslöserads sowie einen Gewichtsbereich auf. Der Gewichtsbereich ist zweckmäßigerweise so ausgebildet, dass er nicht in Kontakt mit dem Auslöserad kommt und dass er zur Aufnahme von separaten Zusatzgewichten geeignet ist. Diese separaten Zusatzgewichte dienen dazu, die Auslösegeschwindigkeit der Auslösevorrichtung einzustellen.According to a particularly preferred embodiment, the flyweight simultaneously represent the coupling means. In this preferred solution, at least two additional components and their connection means can be saved with each other. The design of the tripping device becomes simpler and cheaper. The design is kinematically and statically determined, which increases the tolerance ranges to be complied with. The coupling agents acting as flyweight compounds (or the flyweights acting as coupling agents) expediently have a coupling region for loading or contacting the trigger wheel and a weight range. The weight range is expediently designed so that it does not come into contact with the trigger wheel and that it is suitable for receiving separate additional weights. These separate additional weights are used to set the release speed of the release device.
Wenn der Rand der Koppelmittel zumindest teilweise die Form einer archimedischen Spirale hat, erfolgt ein sanftes Beaufschlagen des Auslöserads ohne Ruck mit gemäßigtem Kraftanstieg. Der entsprechend geformte Rand der Koppelmittel liegt zweckmäßigerweise in dem weiter oben als Koppelbereich bezeichneten Bereich. Insbesondere bei dieser Ausgestaltung kann das Bereitstellen eines elastischen Materials besondere Vorteile entfalten, da die als Fliehmassen wirkenden Koppelmittel in Abhängigkeit von der Auslösegeschwindigkeit ggf. unterschiedliche Formen haben können, so dass der Abstand des Rands des Koppelmittels vom Auslöserad ggf. von der Auslegung des Begrenzers abhängt. Diese unterschiedlichen Abstände können bei Beibehaltung aller anderen konstruktiven Größen durch das elastische Material ausgeglichen werden.If the edge of the coupling means at least partially in the form of an Archimedean spiral, gently applying the trigger wheel without jerk occurs with moderate increase in force. The correspondingly shaped edge of the coupling means is expediently in the area designated above as a coupling region. In particular, in this embodiment, the provision of an elastic material can develop particular advantages, since the acting as flyweight coupling means depending on the release speed may possibly have different shapes, so that the distance of the edge of the coupling means from the trigger wheel, if necessary, depends on the design of the limiter , These different distances can be compensated for while maintaining all other structural sizes by the elastic material.
Wenn die Koppelmittel eine Nase aufweisen, welche einen Endanschlag definiert, kann ein übermäßiges Beaufschlagen des Auslöserads durch die Koppelmittel vermieden werden. Zu Beginn des Auslösevorgangs befindet sich das Auslöserad in Ruhe. Die Koppelmittel rotieren jedoch mit der Geschwindigkeit des Begrenzerrads um das Auslöserad herum und werden dabei - in Abhängigkeit von der Rotationsgeschwindigkeit des Begrenzerrads - um ihre eigene Achse ausgelenkt. Die Koppelmittel sind dabei zweckmäßigerweise so angeordnet, dass die Rotation bzw. Auslenkung um ihre eigene Achse bei Beaufschlagung des Auslöserads zu einer Selbstverstärkung der Beaufschlagung führt. Diese Selbstverstärkung hält solange an, bis das Auslöserad die Rotationsgeschwindigkeit des Begrenzerrads erreicht hat. Um dabei jedoch kein übermäßiges Eindrehen der Koppelmittel zu riskieren, sind diese zweckmäßigerweise mit einem Endanschlag ausgestattet. Schlägt dieser an das Auslöserad an, kann kein weiteres Eindrehen stattfinden.If the coupling means have a nose which defines an end stop, an excessive loading of the trigger wheel by the coupling means can be avoided. At the beginning of the tripping process, the tripping wheel is at rest. However, the coupling means rotate around the trigger wheel at the speed of the governor wheel, being deflected about its own axis depending on the speed of rotation of the governor wheel. The coupling means are expediently so arranged that the rotation or deflection about its own axis when applied to the trigger wheel leads to a self-boosting of the admission. This self-energizing continues until the trigger wheel has reached the rotational speed of the governor wheel. However, in order to avoid excessive screwing the coupling agent, these are expediently equipped with an end stop. If this strikes against the trigger wheel, no further screwing can take place.
Zweckmäßigerweise sind die Fliehmassen miteinander mittels einer Seilverbindung gekoppelt und zugbelastet federvorgespannt, so dass ein linearer Zusammenhang zwischen der Federbelastung und der Auslenkung der Fliehmassen besteht. Die Fliehmassen sind paarweise auf dem Begrenzerrad angeordnet und mittels einer Seilverbindung verbunden, um Gravitationseffekte zu kompensieren. Weiterhin sind sie gegen die Fliehkraftwirkung so vorgespannt, dass eine für eine Beaufschlagung des Auslöserads ausreichende Auslenkung der Fliehmassen erst bei Erreichen der Auslösegeschwindigkeit stattfindet. Zweckmäßigerweise sind dabei die Fliehmassen und die Feder so bemessen, dass unterhalb der Auslösegeschwindigkeit keine Auslenkung der Fliehmassen stattfindet. Auf diese Weise bleiben die genannten Bauteile während des Normalbetriebs in Ruhe, so dass keine Abnutzung stattfindet. Durch die federvorgespannte Seilverbindung kann ein linearer Zusammenhang zwischen Federbelastung und Auslenkung der Fliehmassen bereitgestellt werden, so dass die erwünschte Auslösegeschwindigkeit auf sehr einfache Weise einzustellen ist.Conveniently, the flyweights are coupled to each other by means of a cable connection and tensioned spring loaded, so that there is a linear relationship between the spring load and the deflection of the flyweight. The flyweights are arranged in pairs on the governor wheel and connected by a cable connection to compensate for gravitational effects. Furthermore, they are biased against the centrifugal force so that sufficient for an actuation of the trigger wheel deflection of the flyweight takes place only when reaching the triggering speed. Conveniently, the flyweight and the spring are dimensioned so that below the release speed no deflection of the flyweight takes place. In this way, the components mentioned during normal operation remain at rest, so that no wear takes place. By the spring-biased cable connection, a linear relationship between the spring load and deflection of the flyweight can be provided so that the desired release speed is set in a very simple manner.
Vorteilhafterweise sind die Fliehmassen so auf dem Begrenzerrad angeordnet, dass der Schwerpunkt der Fliehmassen einen kleineren Abstand von der Drehachse des Begrenzerrads aufweist als den Abstand der Drehachse der Fliehmassen von der Drehachse des Bagrenzerrads. Mit anderen Worten liegt der Schwerpunkt der Fliehmassen näher an der Drehachse des Begrenzerrads als ihre eigene Drehachse. Diese Anordnung führt dazu, dass die Ansprechgeschwindigkeit der Auslösevorrichtung von der Rotationsbeschleunigung des Drehrades insofern abhängt, als eine Beschleunigung des Begrenzerrads zu einem schnelleren Ansprechen der Auslösevorrichtung führt. Dieses Verhalten ist insbesondere für Seilbruchfälle besonders vorteilhaft, da dort eine große Beschleunigung des Fahrkorbs nach unten stattfindet und so ein möglicht frühes Auslösen wünschenswert ist.Advantageously, the flyweights are arranged on the governor wheel so that the center of gravity of the flyweights has a smaller distance from the axis of rotation of the governor wheel than the distance of the axis of rotation of the flyweights from the axis of rotation of the Bagrenzerrads. In other words, the center of gravity of the flyweights is closer to the axis of rotation of the governor than its own axis of rotation. This arrangement results in that the response speed of the triggering device depends on the rotational acceleration of the rotary wheel in so far as an acceleration of the governor wheel leads to a faster response of the triggering device. This behavior is particularly advantageous for rope breakage, since there is a large acceleration of the car down and so a possible early release is desirable.
Wenn das Begrenzerrad mit einer zentralen mitrotierenden Welle versehen ist, kann diese beispielsweise als Montageplatz für andere Einheiten dienen. Insbesondere können so Drehgeber u.ä. einfach in einer Aufzugsanlage platziert werden.If the governor wheel is provided with a central co-rotating shaft, this can serve, for example, as a mounting space for other units. In particular, so encoders u.ä. simply be placed in an elevator system.
Ein erfindungsgemäßer Geschwindigkeitsbegrenzer für einen Aufzug ist mit einer erfindungsgemäßen Auslösevorrichtung zum Auslösen einer Seilbremse und/oder zum Betätigen eines Schalters zum Stillsetzen eines Aufzugantriebs ausgestattet.An inventive speed limiter for an elevator is equipped with a tripping device according to the invention for triggering a cable brake and / or for actuating a switch for stopping an elevator drive.
Eine vorteilhafte Seilbremse umfasst ein viergliedriges Koppelgetriebe, insbesondere eine Schubkurbel. Damit kann eine große Hebelwirkung erzeugt werden, so dass eine große Bremskraft, welche beispielsweise von einer gespannten Feder bereitgestellt werden kann, durch eine kleine Auslösekraft gehalten werden kann. Diese kleine Auslösekraft wird vom Auslöserad aufgenommen.An advantageous cable brake comprises a four-link coupling gear, in particular a sliding crank. Thus, a large leverage can be generated, so that a large braking force, which, for example, from a cocked Spring can be provided, can be held by a small release force. This small release force is absorbed by the trigger wheel.
Zweckmäßigerweise umfasst die Seilbremse eine exzentrische Schubkurbel, bei der insbesondere die Exzentrizität größer als die Kurbellänge ist.Conveniently, the rope brake comprises an eccentric crank, in particular, the eccentricity is greater than the crank length.
Vorteilhafterweise drückt dabei das die Kurbel und das Pleuel verbindende Gelenk über einen Auslösehebel auf das Auslöserad. Der Auslösehebel ist in einem metastabilen Zustand am Auslöserad gehaltert. Das Gelenk wird dadurch durchgedrückt, so dass die Seilbremse gelüftet ist. Löst die Auslösevorrichtung aus, wird das Auslöserad in Rotation versetzt und drückt dadurch den Auslösehebel weg. Damit kann sich das Gelenk bewegen, so dass das Pleuel nachrücken kann und die Seilbremse schließt.Advantageously, the joint connecting the crank and the connecting rod presses on the trigger wheel via a release lever. The trigger is held in a metastable state on the trigger wheel. The joint is thereby pushed through, so that the rope brake is released. Triggers the triggering device, the trigger wheel is set in rotation, thereby pushing the release lever away. Thus, the joint can move, so that the connecting rod can move up and the rope brake closes.
Zur Platzersparnis bietet es sich an, die Seilbremse mittels wenigstens einer Tellerfeder vorzuspannen. Zur einfachen Lüftung der Seilbremse kann eine Schraubanordnung vorgesehen sein, bei der bspw. mittels einer einzuschraubenden Schraube oder Mutter ein dahinter befindliches Übertragungselement, wie bspw. eine Beilagscheibe, die Feder (Tellerfeder, Spiralfeder u.ä.) spannt.To save space, it is advisable to bias the rope brake by means of at least one plate spring. For easy ventilation of the rope brake, a screw arrangement may be provided, in which, for example, by means of a screw or nut to be screwed, a transmission element located behind it, such as, for example, a washer, clamps the spring (plate spring, spiral spring, etc.).
Vorteilhafterweise kann das Begrenzerrad beidseitig bestückt sein. Auf einer Seite sitzen Fliehmassen mit einem Auslöserad zum Auslösen der Seilbremse, wohingegen auf der anderen Seite Fliehmassen und ein Auslöserad zum Betätigen eines elektrischen Schalters angeordnet sind. Durch die zweiseitige Ausführung können unterschiedliche Auslösegeschwindigkeiten für die Seilbremse und den elektrischen Schalter bereitgestellt und eingestellt werden. Insbesondere können dadurch die von gängigen Aufzugnormen geforderten Parameter "Auslösegeschwindigkeit" (mechanischer Nothalt) und "Vorabschaltgeschwindigkeit" (elektrischer Nothalt) unabhängig voneinander eingestellt werden.Advantageously, the Begrenzerrad be equipped on both sides. Flywheels with a trigger wheel for releasing the rope brake are seated on one side, whereas flywheels and a trigger wheel for actuating an electrical switch are arranged on the other side. The two-sided design can be different Triggering speeds for the rope brake and the electrical switch are provided and adjusted. In particular, the parameters required by standard elevator standards "release speed" (mechanical emergency stop) and "pre-switch-off speed" (electrical emergency stop) can thereby be set independently of one another.

Die Auslösevorrichtung 100 weist einen Träger 101 auf, an dem insbesondere auch die auszulösenden Elemente, wie z. B. eine Seilbremse oder ein elektrischer Schalter, angebracht werden können. An der Halterung 101 ist ein Begrenzerrad 102 drehbar gelagert, das von einem Begrenzerseil 103 bei Betrieb in Drehung versetzt wird. Das Begrenzerrad 102 ist an einem Lager 110 drehbar gelagert. Das Begrenzerrad 102 weist zwei an Achsen 104a, 104b drehbar gelagerte Fliehmassen 105a, 105b auf, welche gleichzeitig als Koppelmittel wirken.The triggering
In der dargestellten Grundstellung sind die Fliehmassen nicht ausgelenkt und beaufschlagen das Auslöserad nicht. Die Fliehmassen 105a, 105b weisen jeweils einen Koppelbereich 106a, 106b sowie eine einen Anschlag definierende Nase 107a, 107b auf. Weiterhin weisen die Fliehmassen 105a, 105b anbringbare und entfernbare Zusatzgewichte 108a, 108b auf, um die Auslösegeschwindigkeit der Auslösevorrichtung 100 einzustellen bzw. vorzugeben.In the illustrated basic position, the flyweights are not deflected and do not act on the trigger wheel. The
Die Fliehmassen/Koppelmittel 105a, 105b sind mittels einer Seilzugverbindung 200 verbunden, welche über eine Feder 201 vorgespannt ist. Somit muss eine vorgegebene Fliehkraft erreicht werden, um die Federvorspannkraft zu überwinden. Die Federvorspannkraft ist zweckmäßigerweise so vorgegeben, dass die Fliehmassen/Koppelmittel 105a, 105b während des Normalbetriebs in Ruhe bleiben und nicht ausgelenkt werden. Damit können Verschleiß sowie störende Geräusche, insbesondere Klappern, vermieden werden. Die Seilverbindung 200 dient insbesondere zum Gravitationsausgleich.The flyweight / coupling means 105a, 105b are connected by means of a
Das Begrenzerrad 102 ist drehfest mit einer zentralen Welle 111 verbunden, die sich synchron zum Begrenzerrad dreht und beispielsweise zur Aufnahme eines Drehgebers verwendet werden kann. So kann auf einfache Weise die Drehgeschwindigkeit des Begrenzerrades beispielsweise elektronisch abgetastet werden.The
An dem Lager 110 ist weiterhin ein Auslöserad 120 drehbar gelagert, welches sich während des Betriebs im nicht ausgelösten Zustand in Ruhe befindet. Das Auslöserad 120 weist einen Ring 121 aus elastischem Material auf, welcher insbesondere zum Ausgleich von Toleranzen sowie zur Reibungsvermittlung dient.On the
Im dargestellten, nicht ausgelösten Zustand (Grundstellung) sind die Fliehmassen/Koppelmittel 105a, 105b nicht ausgelenkt und stehen deshalb nicht in Kontakt mit dem Auslöserad 120. Überschreitet die Drehgeschwindigkeit des Begrenzerrades 102 jedoch die vorgegebene Auslösegeschwindigkeit, werden die Fliehmassen/Koppelmittel 105a, 105b gegen die Kraft der Feder 201 ausgelenkt und nähern sich dem Auslöserad bis zur Berührung an. Je nach Abstand ist dafür ein Schwenkwinkel von bis zu 30° nötig. Schließlich kommen die Koppelbereiche 106a, 106b in Kontakt mit dem elastischen Material 121 des Begrenzerrads 120. Im weiteren Verlauf wälzen die Fliehmassen/Koppelmittel 105a, 105b durch die Haftreibung selbsttätig weiter ein, bis das Auslösemoment erreicht ist. Auf diese Weise wird die Drehbewegung des Begrenzerrads 102 an das Auslöserad 120 übertragen, welches in der Folge in eine Drehbewegung versetzt wird. Ab einem Schwenkwinkel von etwa 70° wird ein weiteres Einwälzen durch das Auftreffen der speziell geformten Nasen verhindert. Durch diese Begrenzung des maximalen Schwenkwinkels werden die Fliehmassen/Koppelmittel am Durchschlagen gehindert und gleichzeitig wird das System vor Überlastung geschützt. Das Auftreffen der an jeder Fliehmasse/Koppelmittel ausgeformten Nase 107a bzw. 107b am Auslöserad 120 bewirkt eine deutliche Verschiebung des Kraftangriffspunktes. In der Folge ändert sich das Verhältnis zwischen der Normalkraft und der zum weiteren Einwälzen nötigen Haftreibungskraft so stark, dass es zum Rutschen kommt. Das System ist so ausgelegt, dass das Auslösemoment an diesem Punkt bereits sicher überschritten ist. Das weitere Anwachsen des Moments durch die Trägheit des Auslöserades 120 wird bereits durch die Dämpfungswirkung des elastischen Belags 121 stark gemindert und durch das Rutschen nach oben begrenzt.In the illustrated, untripped condition (basic position), the flyweights / coupling means 105a, 105b are not deflected and therefore are not in contact with the
Eine Drehbewegung des Auslöserads 120 wiederum kann zum Auslösen unterschiedlichster Funktionen, beispielsweise eines elektrischen Schalters oder einer Seilbremse, wie es nachfolgend anhand
In
Ein Auslösehebel 412 liegt in einer metastabilen Stellung an einem Zapfen 430 sowie an dem Auslöserad 120 an. Die Kurbel 413 ist an einer Achse 414 drehbar gelagert und an einem Gelenk 415 mit dem Pleuel 411 und dem Auslösehebel 412 verbunden. In der gelüfteten Stellung der Bremse 400 drückt der Auslösehebel 412 das Gelenk 415 in der gezeigten Ansicht nach unten, so dass das Pleuel 411 den Bremsbacken 422 nach rechts drückt.A
Wird das Auslöserad 120 jedoch durch Beaufschlagung mit den Koppelmitteln 105a, 105b in Drehung (im Uhrzeigersinn) versetzt, wird der am Auslöserad anstehende Auslösehebel 412 in der Zeichnung nach links weggedrückt, wodurch das Gelenk 415 freigegeben wird und sich nach links oben bewegen kann. In der Folge drückt die Tellerfeder 421 den Bremsbacken 422 gegen den Bremsbacken 424 und klemmt das dazwischen laufende Seil 103 ein.However, when the
Um einen einmal ausgelösten Begrenzer auf einfache Weise wieder in die Grundstellung zurückzuführen, ist das Tellerfederpaket 421 mit einer Gewindeanordnung 423 versehen, durch deren Betätigung das Tellerfederpaket 421 vorgespannt werden kann. Damit wird die auf den Bremsbacken 422 wirkende Kraft gelöst, so dass das Pleuel 411 und der Auslösehebel 412 wieder in die gezeigte Stellung gebracht werden können. Aus Sicherheitsgründen muss anschließend sichergestellt werden, dass die Gewindeanordnung 423 wieder gelöst wird, um den Bremsbacken 422 vorzuspannen.To return a once triggered limiter in a simple way back to the normal position, the

Die besondere Konstruktion führt zu einer Robustheit, welche übliche Fertigungstoleranzen ohne nachteilige Wirkung zulässt.
