- the braking device shown there includes a fluidic brake unit which can cooperate with a brake rail, an actuating device which can actuate the brake unit and a connecting means which connects the brake unit with the brake unit in a force-active manner.
- the actuating device is a hydraulic pressure station, which is connected via hydraulic connecting means to individual brake units and thereby the hydraulic Brake units activated by force.
- Force-active means that a generated in the actuator hydraulic pressure actively defines a resulting in the brake unit contact pressure of brake pads to the brake rail.
- This solution uses hydraulic pressure generators. This is expensive and expensive in procurement and maintenance. Such components are also noisy and safety precautions must be taken to limit the effects of leaks.
- An elevator car according to the preamble of claim 1 is in GB-A-1111425 disclosed.
- the object of the invention is now to provide a braking device which can be quickly brought into use in an irregularity in the operation of an elevator car and quickly brought back into its ready position after their use.
- the device should be quiet and easy to use.
- An elevator car arranged in a driving shaft is equipped with a braking device for holding and braking the elevator car.
- the braking device consists of a brake unit which, with appropriate operation, can cooperate with a brake rail.
- the braking device further includes a Actuating device, which can produce an actuator force FA, and a connecting means, which connects the actuating device for transmitting the actuator force FA with the brake unit.
- a force-active connection means that the brake unit generates a contact force FN and thus ei-ne, resulting from a Bremsreibwert, resulting braking force, which is directly dependent on the Aktuatorkraft FA.
- a small contact force FN thus causes a small braking force
- a large actuator force FA causes a correspondingly large contact force FN.
- the connecting means is now a traction means and the brake unit is designed in such a way that it is in the open position in the unloaded position, ie when no actuator force FA is present.
- Open position means the braking device, or, the brake unit does not brake.
- pulling means advantageously a pull rope, a pull rod or a pull chain is used.
- the advantage of this invention is that in an irregularity in the operation of an elevator car, the braking device by means of the mechanical connection means, or the traction means quickly brought into use and can be quickly brought back into their ready position after ih rem use.
- the brake unit is designed such that it, when no Aktuatorkraft FA is present, in the open position, and the connecting means is carried out by the traction means, as a quick and safe operation and also a slight provision can be made.
- this device is very quiet, since during operation of the elevator system no pumps or the like must be in operation.
- the decor is simple in the Application, as it can be easily checked and understood by a professional. This arises already from the fact that the principle of this braking device has long been known and proven in bicycles.
- this braking device is arranged in the area of the elevator car.
- the braking device can be easily used to hold the elevator car in a floor or the braking device can in an unexpected behavior of the elevator car, if they are suddenly slipped away, for example, in the open floor access. Thanks to the simple operation, the braking device can be easilytechnischge sets.
- the brake rail is a component of a guide rail on which the elevator car is guided along.
- the location of the braking device is arbitrary. It can be built up or underneath the elevator car or below the elevator car, or it can be integrated in the elevator car structure, for example in a canopy, cabin floor or in side walls.
- the braking device has at least two brake units, which are advantageously arranged on opposite boundary edges of the elevator car and which cooperate with a respective brake, or guide rail.
- the actuating device generates an actuator force FA for actuating the brake units (9), this actuator force FA being transmitted substantially symmetrically to the brake units by means of connecting means.
- the actuating device is essentially centrally located in the middle between two brake units, wherein in each case a first connecting means with a first brake unit and a second connecting means with a second brake unit is connected.
- This embodiment is advantageous because the holding and braking forces due to the two-sided arrangement of the brake units are introduced substantially symmetrically in the elevator car and the actuator can be centrally, for example, in the middle of a roof of the elevator car. This makes the control easy.
- a position of the actuating device is essentially defined by a balance of the first and the second connecting means.
- an identical actuator force is given to the two brake units.
- a limiting means is provided, which limits a lateral displacement of the actuating device in case of failure of one of the connecting means and thus maintains the actuator force FA in the remaining connecting means. This increases the safety of the braking device, since a residual braking force remains despite failure of a connecting means. If, for example, the braking force of the braking device is designed with a safety factor of 2, holding would be ensured even if one of the connecting means fails.
- the brake unit includes a power transmission, which converts the actuator force FA transmitted by the connecting means into a contact pressure FN and at the same time effects a reinforcement of this contact force FN.
- a lever mechanism which converts the actuator force FA into a contact force FN via a toggle lever, via eccentrics or else via dome disks.
- With such translation or reinforcing means can be achieved large power gains.
- This is advantageous because commercially available connecting means such as a Bowden cable can be used as connecting means.
- a tensioning device is used to generate the actuator force FA in the actuating device.
- the tensioning device when appropriately controlled, pulls or relieves the first and second connection means under control. This is done for example via a spindle gear, which attracts or relaxes one or both connecting means to the actuating device.
- the spindle gear is designed such that the Glasspannvorides retains its current set position in the absence of a control signal or supply energy.
- the supply energy supplies the drive of the spindle gear or the actuating device with preferably electrical energy and the control signal is the control command to tension the connecting means or to relax the connecting means.
- the advantages are to be seen in the fact that the braking force determination is done centrally in the common actuator and the Actuator force inevitably equivalent to the decentralized braking units is transmitted. In addition, it is ensured with the selected Glasspannvoriques that a set state is maintained.
- the actuator force is essentially transmitted by train. This allows the use of favorable traction means such as a pull rope, a pull chain or a pull rod.
- the actuator includes a sensor for fixing the current actuator force FA and this sensor is optionally used for control, regulation and monitoring.
- the sensor is, for example, a force measuring sensor or a spring-loaded position sensor, which detects a compression of a spring, via which the actuator force is transmitted, and accordingly, the position sensor is a measure of the Aktuatorkraft.
- the position sensor for example, the positions of the actuator force are reached or the actuating device is adjusted, and the tensioning device is controlled on the basis of these signals.
- actual force or pressure sensors can be used. The use of such a sensor is advantageous because a certain tensile force can be achieved independently of a state of wear and further, that any deviations can be detected and accordingly reported to a service station.
- connection means with a pulley As an advantageous extension results in the possibility to umzucite the connecting means with a pulley.
- the actuator force FA transmitted by the connection means to the brake unit can thus be amplified in accordance with a pulley transfer factor. In order to a holding or braking force required for a particular elevator installation can be achieved.
- the braking device can quickly, or preventively, be brought into action and they can be reset after the elimination of the fault reason just as quickly.
- the braking device can be mounted in addition to a safety gear on the elevator car. This is advantageous because it protects a known and safety-tested emergency brake system the elevator car against extreme errors, such as the failure of suspension elements, and the task of the braking device primarily for errors and / or use in areas of stops or in the vicinity of track limits, such as Fahrschachtende or another elevator car, can be aligned.

Die Aufzugsanlage beinhaltet zu diesem Zweck eine oder mehrere Aufzugskabinen, zur Aufnahme der Güter oder Personen, welche Aufzugskabine entlang einer Führungsbahn verfahrbar ist. In der Regel ist die Aufzugsanlage in einem Gebäude eingebaut und die Aufzugskabine transportiert Güter oder Personen von und zu verschiedenen Stockwerken dieses Gebäudes. In einer gebräuchlichen Ausführung ist die Aufzugsanlage in einem Fahrschacht des Gebäudes eingebaut und sie enthält neben der Aufzugskabine Tragmittel, welche die Aufzugskabine mit einem Gegengewicht verbinden. Mittels eines Antriebes, der wahlweise auf die Tragmittel, direkt auf die Aufzugskabine oder auf das Gegengewicht einwirkt, wird die Aufzugskabine bewegt. Die Führungsbahn zum Führen der Aufzugskabine ist vielfach eine Führungsschiene, welche am Gebäude, bzw. im Fahrschacht befestigt ist. Derartige Aufzugsanlagen sind mit Bremssystemen ausgerüstet, welche einerseits die Aufzugskabine in einer Stockwerkhalt halten und /oder die Aufzugskabine in einem Fehlerfalle abbremsen und halten können. Das Bremssystem wirkt zum Zwecke des Bremsens mit einer Bremsbahn zusammen, welche in der Regel in die Führungsschiene integriert ist. Derartige Aufzugsanlage lassen sich selbstverständlich auch ausserhalb des Gebäudes anordnen, wobei dann die Führungsschienen Teil eines Gerüstes sein können. Übliche Fangvorrichtungen sind nicht ausgelegt um die Aufzugskabine in einer Halteposition, beispielsweise zum Beladen der Aufzugskabine halten zu können, da sie nur von einem Service-Fachmann wieder in Betrieb genommen werden können.An elevator system essentially serves the vertical transport of goods or persons.

Eine in einem Fahrschacht angeordnete Aufzugskabine ist mit einer Bremseinrichtung zum Halten und Bremsen der Aufzugskabine ausgerüstet. Die Bremseinrichtung besteht aus einer Bremseinheit welche, bei entsprechender Betätigung, mit einer Bremsschiene zusammenwirken kann. Die Bremseinrichtung beinhaltet weiter eine Betätigungseinrichtung, welche eine Aktuatorkraft FA erzeugen kann, und ein Verbindungsmittel, welches die Betätigungseinrichtung zum Übertragen der Aktuatorkraft FA kraftaktiv mit der Bremseinheit verbindet. Eine kraftaktive Verbindung bedeutet, dass die Bremseinheit eine Anpresskraft FN und damit ei-ne, durch einen Bremsreibwert definierte, resultierende Bremskraft erzeugt, welche direkt abhängig von der Aktuatorkraft FA ist. Eine geringe Anpresskraft FN bewirkt somit eine kleine Bremskraft, eine grosse Aktuatorkraft FA bewirkt eine entsprechend grosse Anpresskraft FN. Erfindungsgemäss ist nun das Verbindungsmittel ein Zugmittel und die Bremseinheit ist derart ausgeführt, dass sie in unbeaufschlagter Stellung, d.h. wenn keine Aktuatorkraft FA anliegt, in Offenstellung ist. Offenstellung bedeutet, die Bremseinrichtung, bzw., die Bremseinheit bremst nicht. Als Zugmittel wird vorteilhafterweise ein Zugseil, eine Zugstange oder auch eine Zugkette verwendet.An elevator car arranged in a driving shaft is equipped with a braking device for holding and braking the elevator car.

Dank der einfachen Betätigung kann die Bremseinrichtung einfach wieder zurückge setzt werden. In der Regel ist die Bremsschiene ein Bestandteil einer Führungsschiene an welcher die Aufzugskabine entlang geführt wird. Auch ist der Anbauort der Bremseinrichtung beliebig. Sie kann oberhalb der Aufzugskabine oder unterhalb der Aufzugskabine auf, bzw. untergebaut sein, oder sie kann in die Aufzugskabinenstruktur, bspw. in einem Kabinendach, Kabinenboden oder auch in Seitenwänden integriert sein.According to the invention, this braking device is arranged in the area of the elevator car. Thus, the braking device can be easily used to hold the elevator car in a floor or the braking device can in an unexpected behavior of the elevator car, if they are suddenly slipped away, for example, in the open floor access. Thanks to the simple operation, the braking device can be easily zurückge sets. As a rule, the brake rail is a component of a guide rail on which the elevator car is guided along. Also, the location of the braking device is arbitrary. It can be built up or underneath the elevator car or below the elevator car, or it can be integrated in the elevator car structure, for example in a canopy, cabin floor or in side walls.
In einer vorteilhaften Ausführung weist die Bremseinrichtung mindestens zwei Bremseinheiten auf, welche vorteilhafterweise an entgegen gesetzten Begrenzungskanten der Aufzugskabine angeordnet sind und welche mit jeweils einer Brems-, bzw. Führungsschiene zusammenwirken. Die Betätigungseinrichtung generiert eine Aktuatorkraft FA zur Betätigung der Bremseinheiten (9), wobei diese Aktuatorkraft FA mittels Verbindungsmittel im Wesentlichen symmetrisch zu den Bremseinheiten übertragen wird. Entsprechend ist die Betätigungseinrichtung im Wesentlichen zentral, in der Mitte zwischen zwei Bremseinheiten angeordnet, wobei jeweils ein erstes Verbindungsmittel mit einer ersten Bremseinheit und eine zweites Verbindungsmittel mit einer zweiten Bremseinheit verbunden ist.In an advantageous embodiment, the braking device has at least two brake units, which are advantageously arranged on opposite boundary edges of the elevator car and which cooperate with a respective brake, or guide rail. The actuating device generates an actuator force FA for actuating the brake units (9), this actuator force FA being transmitted substantially symmetrically to the brake units by means of connecting means. Accordingly, the actuating device is essentially centrally located in the middle between two brake units, wherein in each case a first connecting means with a first brake unit and a second connecting means with a second brake unit is connected.
Diese Ausführung ist vorteilhaft, da die Halte- und Bremskräfte wegen der beidseitigen Anordnung der Bremseinheiten im Wesentlichen symmetrisch in die Aufzugskabine eingeleitet werden und die Betätigungseinrichtung kann zentral, beispielsweise in der Mitte des eines Dachs der Aufzugskabine angeordnet werden. Dadurch wird die Kontrolle einfach.This embodiment is advantageous because the holding and braking forces due to the two-sided arrangement of the brake units are introduced substantially symmetrically in the elevator car and the actuator can be centrally, for example, in the middle of a roof of the elevator car. This makes the control easy.
Vorteilhafterweise ist eine Lage der Betätigungseinrichtung im Wesentlichen durch ein Gleichgewicht des ersten und des zweiten Verbindungsmittels definiert. Dadurch ist eine identische Aktuatorkraft zu den beiden Bremseinheiten gegeben. Im Weiteren ist ein Begrenzungsmittel vorgesehen, welches bei Versagen eines der Verbindungsmittel, eine seitliche Verschiebung der Betätigungseinrichtung begrenzt und somit die Aktuatorkraft FA im verbleibenden Verbindungsmittel aufrechterhält. Dies erhöht die Sicherheit der Bremseinrichtung, da trotz Ausfall eines Verbindungsmittels eine Restbremskraft bestehen bleibt. Ist beispielsweise die Bremskraft der Bremseinrichtung mit einem Sicherheitsfaktor von 2 ausgelegt, wäre ein Halten auch bei Versagen eines der Verbindungsmittel gewährleistet. Der Ausfall eines der Verbindungsmittel bzw. ein Berühren des Begrenzungsmittels durch die Betätigungseinrichtung kann mit einem Schalter überwacht werden und bei Feststellung dieses Zustandes kann eine Wartung initialisiert werden oder ein Betrieb der Aufzugsanlage kann eingeschränkt werden. Vorteilhafterweise beinhaltet die Bremseinheit eine Kraftübersetzung, welche die vom Verbindungsmittel übertragene Aktuatorkraft FA in eine Anpresskraft FN umsetzt und gleichzeitig eine Verstärkung dieser Anpresskraft FN bewirkt. Dies wird beispielsweise durch eine Hebelmechanik erreicht, welche die Aktuatorkraft FA über einen Kniehebel, über Excenter oder auch über Kalottenscheiben in eine Anpresskraft FN umsetzt. Mit derartigen Übersetzungs- oder Verstärkungsmittel lassen sich grosse Kraftverstärkungen erreichen. Dies ist vorteilhaft, da deswegen handelsübliche Verbindungsmittel wie beispielsweise ein Bowdenzug als Verbindungsmittel verwendet werden können.Advantageously, a position of the actuating device is essentially defined by a balance of the first and the second connecting means. As a result, an identical actuator force is given to the two brake units. In addition, a limiting means is provided, which limits a lateral displacement of the actuating device in case of failure of one of the connecting means and thus maintains the actuator force FA in the remaining connecting means. This increases the safety of the braking device, since a residual braking force remains despite failure of a connecting means. If, for example, the braking force of the braking device is designed with a safety factor of 2, holding would be ensured even if one of the connecting means fails. The failure of one of the connecting means or contact of the limiting means by the actuator can be monitored with a switch and upon detection of this condition, a maintenance can be initialized or operation of the elevator system can be limited. Advantageously, the brake unit includes a power transmission, which converts the actuator force FA transmitted by the connecting means into a contact pressure FN and at the same time effects a reinforcement of this contact force FN. This is achieved, for example, by a lever mechanism which converts the actuator force FA into a contact force FN via a toggle lever, via eccentrics or else via dome disks. With such translation or reinforcing means can be achieved large power gains. This is advantageous because commercially available connecting means such as a Bowden cable can be used as connecting means.
In einer Variante der Erfindung wird zur Erzeugung der Aktuatorkraft FA in der Betätigungseinrichtung eine Zugspannvorrichtung verwendet. Die Zugspannvorrichtung zieht, wenn entsprechend angesteuert das erste und das zweite Verbindungsmittel gesteuert zusammen oder entlastet es. Dies erfolgt beispielsweise über ein Spindelgetriebe, welches eines oder beide Verbindungsmittel zur Betätigungseinrichtung zuzieht bzw. entspannt. Das Spindelgetriebe ist derart ausgeführt dass die Zugspannvorrichtung bei Fehlen eines Steuersignals oder Versorgungsenergie ihre aktuell eingestellte Position behält. Die Versorgungsenergie versorgt den Antrieb des Spindelgetriebes bzw. der Betätigungseinrichtung mit vorzugsweise elektrischer Energie und das Steuersignal gibt den Steuerbefehl das Verbindungsmittel zu spannen oder das Verbindungsmittel zu entspannen. Die Vorteile sind darin zu sehen, dass die Bremskraftbestimmung zentral in der gemeinsamen Betätigungseinrichtung erfolgt und die Aktuatorkraft zwangsläufig gleich wirkend zu den dezentralen Bremseinheiten übertragen wird. Zudem ist mit der gewählten Zugspannvorrichtung sichergestellt, dass ein eingestellter Zustand beibehalten wird. Die Aktuatorkraft wird im Wesentlichen durch Zug übertragen. Dies erlaubt die Verwendung günstiger Zugmittel wie beispielsweise eines Zugseils, einer Zugkette oder einer Zugstange.In a variant of the invention, a tensioning device is used to generate the actuator force FA in the actuating device. The tensioning device, when appropriately controlled, pulls or relieves the first and second connection means under control. This is done for example via a spindle gear, which attracts or relaxes one or both connecting means to the actuating device. The spindle gear is designed such that the Zugspannvorrichtung retains its current set position in the absence of a control signal or supply energy. The supply energy supplies the drive of the spindle gear or the actuating device with preferably electrical energy and the control signal is the control command to tension the connecting means or to relax the connecting means. The advantages are to be seen in the fact that the braking force determination is done centrally in the common actuator and the Actuator force inevitably equivalent to the decentralized braking units is transmitted. In addition, it is ensured with the selected Zugspannvorrichtung that a set state is maintained. The actuator force is essentially transmitted by train. This allows the use of favorable traction means such as a pull rope, a pull chain or a pull rod.
Vorteilhafterweise beinhaltet die Betätigungseinrichtung einen Sensor zur Fest stellung der aktuellen Aktuatorkraft FA und dieser Sensor wird wahlweise zur Steuerung, Regelung und Überwachung verwendet. Der Sensor ist beispielsweise ein Kraftmesssensor oder ein federbelasteter Positionssensor, welcher eine Kompression einer Feder, über welche die Aktuatorkraft übertragen wird, feststellt, und dementsprechend der Positionssensor ein Maß für die Aktuatorkraft darstellt. Im Positionsensor werden beispielsweise die Positionen Aktuatorkraft erreicht oder Betätigungseinrichtung eingestellt und aufgrund dieser Signale die Zugspannvorrichtung gesteuert. Selbstverständlich sind auch eigentliche Kraft- oder Drucksensoren verwendbar. Die Verwendung eines derartigen Sensors ist vorteilhaft, da dadurch eine bestimmte Zugkraft unabhängig eines Verschleisszustandes erreicht werden kann und weiter, dass allfällige Abweichungen erkannt und dementsprechend einer Servicestelle gemeldet werden können.Advantageously, the actuator includes a sensor for fixing the current actuator force FA and this sensor is optionally used for control, regulation and monitoring. The sensor is, for example, a force measuring sensor or a spring-loaded position sensor, which detects a compression of a spring, via which the actuator force is transmitted, and accordingly, the position sensor is a measure of the Aktuatorkraft. In the position sensor, for example, the positions of the actuator force are reached or the actuating device is adjusted, and the tensioning device is controlled on the basis of these signals. Of course, actual force or pressure sensors can be used. The use of such a sensor is advantageous because a certain tensile force can be achieved independently of a state of wear and further, that any deviations can be detected and accordingly reported to a service station.
Als vorteilhafte Erweiterung ergibt sich die Möglichkeit, das Verbindungsmittel mit einem Flaschenzug umzuhängen. Die vom Verbindungsmittel zur Bremseinheit übertragene Aktuatorkraft FA kann somit entsprechend einem Umhängefaktor des Flaschenzuges verstärkt werden. Damit lässt sich ein für eine bestimmte Aufzugsanlage erforderliche Halte- bzw. Bremskraft erreichen.As an advantageous extension results in the possibility to umzuhängen the connecting means with a pulley. The actuator force FA transmitted by the connection means to the brake unit can thus be amplified in accordance with a pulley transfer factor. In order to a holding or braking force required for a particular elevator installation can be achieved.
Die Bremseinrichtung kann schnell, oder auch vorbeugend, zur Wirkung gebracht werden und sie kann nach Beseitigung des Störungsgrundes ebenso schnell wieder zurückgestellt werden.The braking device can quickly, or preventively, be brought into action and they can be reset after the elimination of the fault reason just as quickly.
Die Bremseinrichtung kann zusätzlich zu einer Fangvorrichtung an der Aufzugskabine angebaut werden. Dies ist vorteilhaft, da damit ein bekanntes und sicherheitsgeprüftes Notbremssystem die Aufzugskabine gegen extreme Fehler, wie das Versagen von Tragmitteln, schützt und die Aufgabe der Bremseinrichtung primär auf Fehler und/oder Benutzung im Bereiche von Haltestellen oder in der Nähe von Fahrwegbegrenzungen, wie beispielsweise ein Fahrschachtende oder eine andere Aufzugskabine, ausgerichtet werden kann.The braking device can be mounted in addition to a safety gear on the elevator car. This is advantageous because it protects a known and safety-tested emergency brake system the elevator car against extreme errors, such as the failure of suspension elements, and the task of the braking device primarily for errors and / or use in areas of stops or in the vicinity of track limits, such as Fahrschachtende or another elevator car, can be aligned.
