Abstract

The brake system (4) for an elevator cage, to prevent an uncontrolled descent, has a moving brake unit (4.1) with surface teeth facing a fixed rail (4.2) also with a toothed surface structure. The moving brake unit is fitted to the elevator cage, and the fixed rail is at a carrier pillar. When the elevator cage is at the selected floor level, the moving unit is extended to mesh with the teeth at the rail, in a positive fit, to prevent movement of the elevator cage upwards or downwards. The toothed structure of the fixed or moving sections is a rubber strip or an injection molded profile.

Es sind Bremseinrichtungen für Aufzüge bekannt (siehe US-5651429, JP-5024764 und JP-5097344), die aus einem mit der Kabine mitfahrendem Teil und einem an der Schachtwand angeordneten feststehenden Teil bestehen. Sie dienen als Sicherheitsbremse im Fall eines freien Falls.Braking devices for elevators are known (see US-5651429, JP-5024764 and JP-5097344), which consist of a the cabin moving part and one on the shaft wall arranged fixed part exist. They serve as Safety brake in the event of a free fall.

Nachteilig bei diesen bekannten Bremsen ist die Tatsache, dass sie nur für den freien Fall ausgelegt sind und nur in Abwärtsrichtung wirken.A disadvantage of these known brakes is the fact that they are only designed for free fall and only in Look downward.

Der Erfindung liegt die Aufgabe zugrunde, eine Bremseinrichtung für einen Aufzug der eingangs genannten Art vorzuschlagen, welche die vorgenannten Nachteile nicht aufweist und eine sichere und störungsfreie Bremskraft in beiden Fahrrichtungen ermöglicht.The invention has for its object a Braking device for an elevator of the type mentioned to propose which the disadvantages mentioned above are not has and a safe and trouble-free braking force in allows both directions.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1 solved.

Ein Vorteil der Erfindung ist darin zu sehen, dass die Bremseinrichtung als Haltebremse wirken kann. Weiter wird die Haltekraft in beiden Fahrrichtungen, das heisst aufwärts und abwärts, aufgebracht, was zu einer grösseren Sicherheit führt. Es ist kein Wegrutschen möglich.An advantage of the invention is that the Braking device can act as a holding brake. Will continue the holding force in both directions, i.e. upwards and downward, upset, resulting in greater security leads. It is not possible to slip away.

Durch die in den abhängigen Patentansprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Bremseinrichtung möglich.By those listed in the dependent claims Measures are advantageous training and Improvements to those specified in claim 1 Braking device possible.

Die formschlüssige Zusammenwirkung des beweglichen Teils mit dem feststehenden Teil führt zu einem sicheren Eingriff und darum zu einer sicheren und effizienteren Funktion der Bremseinrichtung.The positive interaction of the moving part with the fixed part leads to a safe engagement and therefore to a safe and more efficient function of the Braking means.

Die Bremseinrichtung erzeugt keine störenden Geräusche, sie arbeitet nämlich geräuscharm.The braking device does not generate any disturbing noises, they works quietly.

Vorteilhaft ist weiter die Tatsache, dass zur Betätigung der Bremseinrichtung kleine Anpress- und folglich kleine Bremslüftkräfte nötig sind.Another advantage is the fact that to operate the Braking device small contact pressure and consequently small Brake release forces are necessary.

Ein weiter Vorteil ist darin zu sehen, dass das Stellglied für die Bremseinrichtung eine kleine Baugrösse aufweist.Another advantage is that the actuator has a small size for the braking device.

Weiter wird eine geringe Anschlussleistung des Stellgliedes benötigt. Die mechanische Leistung zum Lüften der Riegelplatte wird kleiner.Next is a low connected load of the actuator needed. The mechanical performance for airing the Bolt plate gets smaller.

Es ist von Vorteil, dass das Stellglied einen Hebel aufweist, damit die Lüftung der Bremseinrichtung auch manuell erfolgen kann. It is advantageous that the actuator has a lever has, so that the ventilation of the braking device also can be done manually.

Weiter ist die Bremseinrichtung kostengünstig herstellbar.Furthermore, the braking device can be manufactured inexpensively.

    • Figur 1 stellt eine Globalansicht eines Aufzugs dar, der in diesem Beispiel einen direkt mit einer Aufzugskabine 1 verbundenen Aufzugsantrieb aufweist. Es kann sich zum Beispiel um einen Linearantrieb handelt. Die Kabine 1 ist auf einem Rücksackrahmen 2 an einer Tragsäule 3 aufwärts und abwärts in einem nicht gezeigten Aufzugsschacht geführt. Die Tragsäule 3 ist vorzugsweise entlang einer ebenfalls nicht gezeigten Schachtwand angeordnet. Eine als Haltebremse wirkende Bremseinrichtung 4 weist einen sich mit der Kabine 1 beweglichen Teil 4.1 und einen an der Tragsäule 3 angebrachten als Gegenstück wirkenden feststehenden Teil 4.2 auf. Der bewegliche Teil 4.1 ist als Halteriegel ausgebildet, der an dem als verzahnte Riegelbahn ausgebildeten feststehenden Teil 4.2 eingreifen kann. Der Halteriegel 4.1 dient primär zum Halten der Kabine 1 auf Etagenhöhe. Unter der Annahme, dass 50% der Nutzlast mit dem (den) Ausgleichsgewicht(en) ausbalanciert sind, ergibt sich eine Haltekraft von +/- 0.5*Nutzlast*g*Sicherheitsfaktor, wobei g die Gravitationsbeschleunigung ist.FIG. 1 shows a global view of an elevator that is shown in FIG this example one directly with an elevator car 1 connected elevator drive. It can become Example is a linear actuator. The cabin 1 is on a backpack frame 2 on a support column 3 and up led downwards in an elevator shaft, not shown. The Support column 3 is preferably also not along one Shaft wall shown arranged. One as a holding brake acting braking device 4 has one with the cabin 1 movable part 4.1 and one on the support column 3 attached fixed part acting as a counterpart 4.2 on. The movable part 4.1 is a holding bar trained who on the as a toothed crossbar trained fixed part 4.2 can intervene. The Retaining latch 4.1 primarily serves to hold the cabin 1 on Floor height. Assuming that 50% of the payload is with the (the) balance weight (s) are balanced a holding force of +/- 0.5 * payload * g * safety factor, where g is the acceleration of gravity.

    Figur 2 zeigt die Bremseinrichtung 4 in detaillierter Art. Der als Riegel ausgebildete bewegliche Teil 4.1 weist ein Stellglied 5 auf, das zur Lüftung der Bremseinrichtung 4 dient. Der Riegel 4.1 umfasst eine verzahnte Riegelplatte 6, die mit ihren Zähnen/Anschlägen formschlüssig an einem als Riegelbahn 4.2 ausgebildeten Zahnriemen eingreift. Die Zähne/Anschläge der Riegelplatte 6 greifen in entsprechend komplementären Nuten des Zahnriemens ein. Zum Halten der Kabine 1 auf Etagenhöhe tritt somit der bewegliche Teil 4.1 formschlüssig in Wirkverbindung mit dem feststehenden Teil 4.2. Figure 2 shows the braking device 4 in a detailed manner. The movable part 4.1 designed as a latch has a Actuator 5, which for ventilation of the braking device 4th serves. The latch 4.1 comprises a toothed latch plate 6, which with their teeth / stops form-fitting on an as Riegelbahn 4.2 engages trained toothed belt. The Teeth / stops of the locking plate 6 engage accordingly complementary grooves of the toothed belt. To hold the The moving part 4.1 thus enters cabin 1 at floor level form-fitting in operative connection with the fixed part 4.2.

    Aus Figur 3 sind die Hauptbestandteile des beweglichen Teils 4.1 der Bremseinrichtung 4 gemäss Figur 2 deutlicher ersichtlich. Die verzahnte Riegelplatte 6 ist im Rahmen der Zahnteilung in vertikaler Richtung mittels Federelemente 7 federnd gelagert. Das Federelement 7 ist in beiden Fahrtrichtungen wirksam und kann zwei Federstufen haben:

    • weich mit +/- 3 mm und
    • hart von 3 mm bis ca. 50 mm.
    Durch das harte Federelement 7 ist auch eine dynamische Bremsung der Kabine 1 möglich. Wenn die Riegelplatte 6 gegen das harte Federelement 7 vertikal verschiebbar ist, kann trotz Formschluss mechanisch auch eine dynamische Bremsung stattfinden. Das heisst die Bremseinrichtung kann durch das harte Federelement 7, zum Beispiel zusätzlich zu der üblichen Fangvorrichtung, die Kabine 1 bremsen, auch wenn sie in Bewegung ist oder noch nicht ganz stillsteht. Dies ist vor allem bei einem plötzlichen Ausfall des Sicherheitskreises denkbar, bei dem ein Notstop gewünscht ist oder wenn die Haltebremse 4 zum Einsatz kommt kurz vor dem Stillstand der Kabine 1. Ferner kann mit der vertikal federnden Riegelplatte 6 via Weg der Lastzustand der Kabine 1 grob ermittelt werden. Dies kann beispielsweise dadurch erzielt werden, dass die Riegelplatte 6 mit elektrischen Kontakten überwacht wird. Der Antrieb erkennt somit, vor dem Lüften des Riegels, die erforderliche Kraft- oder Momentrichtung.The main components of the movable part 4.1 of the braking device 4 according to FIG. 2 can be seen more clearly from FIG. The toothed locking plate 6 is resiliently mounted in the vertical direction by means of spring elements 7 as part of the tooth division. The spring element 7 is effective in both directions of travel and can have two spring levels:
    • soft with +/- 3 mm and
    • hard from 3 mm to approx. 50 mm.
    The hard spring element 7 also allows dynamic braking of the cabin 1. If the locking plate 6 is vertically displaceable against the hard spring element 7, dynamic braking can take place mechanically despite the positive locking. This means that the braking device can brake the cabin 1 through the hard spring element 7, for example in addition to the usual safety device, even if it is in motion or is not yet completely stationary. This is particularly conceivable in the event of a sudden failure of the safety circuit, in which an emergency stop is desired or when the holding brake 4 is used shortly before the cabin 1 comes to a standstill be determined. This can be achieved, for example, in that the locking plate 6 is monitored with electrical contacts. The drive thus recognizes the required direction of force or torque before the bolt is released.

    In horizontaler Richtung wird die Riegelplatte 6 mit Druckfedern 8 versehen. Die Riegelplatte 6 wird in horizontaler Richtung mittels den Druckfedern 8 in eine Eingriffstellung gebracht und mit dem Stellglied 5 gelüftet. Das Stellglied 5 kann beispielsweise einen Hebel 9 aufweisen, mittels dessen die Bremseinrichtung 4 manuell gelüftet werden kann.In the horizontal direction, the locking plate 6 with Compression springs 8 provided. The locking plate 6 is in horizontal direction by means of the compression springs 8 in one Brought engagement position and released with the actuator 5. The actuator 5 can, for example, a lever 9 have, by means of which the braking device 4 manually can be ventilated.

    Figur 4 zeigt den beweglichen Teil gemäss Figur 3 in zusammengebauten Zustand. Dieser wird mit der Kabine 1 mitfahren.Figure 4 shows the movable part according to Figure 3 in assembled condition. This is with cabin 1 ride.

    Figur 5 zeigt die Riegelplatte 6 des beweglichen Teils 4.1 sowie den feststehenden Teil 4.2 in einer zweiten Ausführungsform der Erfindung. Die Riegelplatte 6 ist als regelmässige Spitzverzahnung 6.1 und der feststehende Teil 4.2 als Gummiband 10 ausgebildet. Im bremsenden Zustand dringt die Spitzverzahnung in das Gummiband 10 ein und bewirkt somit eine formschlüssige Haltebremsung, welche die Bewegung der Kabine sowohl nach unten als auch nach oben gleichzeitig verhindert.Figure 5 shows the locking plate 6 of the movable part 4.1 as well as the fixed part 4.2 in a second Embodiment of the invention. The locking plate 6 is as regular serration 6.1 and the fixed part 4.2 formed as a rubber band 10. In the braking state penetrates the serration into the rubber band 10 and thus brings about a positive holding brake, which the Movement of the cabin both down and up prevented at the same time.

    Figur 6 zeigt die Riegelplatte 6 des beweglichen Teils 4.1 sowie den feststehenden Teil 4.2 in einer dritten Ausführungsform der Erfindung. Die Riegelplatte 6 weist unregelmässig verteilte spitzenförmige/nagelförmige Zähne 6.2 auf, die im bremsenden Zustand in den als Gummiband 10 ausgebildeten feststehenden Teil 4.2 eindringen. Es wird auch in diesem Fall eine formschlüssige Haltebremsung bewirkt, welche die Bewegung der Kabine sowohl nach unten als auch nach oben gleichzeitig verhindert. Figure 6 shows the locking plate 6 of the movable part 4.1 as well as the fixed part 4.2 in a third Embodiment of the invention. The locking plate 6 has irregularly distributed pointed / nail-shaped teeth 6.2 on, in the braking state in the rubber band 10 trained penetrate part 4.2. It will in this case too, a positive stopping brake which causes the movement of the cabin both down as well as prevented upwards.

    Im folgenden wird das Funktionsprinzip der als Haltebremse wirkenden Bremseinrichtung 4 in einer bevorzugten Ausführungsform beschrieben:The following is the principle of operation as a holding brake acting braking device 4 in a preferred Described embodiment:

    Ein direkt mit der Kabine 1 verbundener Aufzugsantrieb bedingt eine Haltebremse 4, welche die Bremskräfte 1:1 aufbringen soll. Im Normalbetrieb wird die Kabine 1, motorisch getrieben beziehungsweise gebremst, auf ein Zielstockwerk gefahren. Bei stillstehender Kabine 1 wird das Stellglied 5 stromlos geschaltet und die verzahnte Riegelplatte 6 rückt mittels den Druckfedern 8 in die verzahnte Riegelbahn 4.2 ein. Die Haltebremse 4 wird deshalb die Kabine 1 stromlos formschlüssig mit der Riegelbahn 4.2 verriegeln. Somit wird mit einer einzigen Riegelplatte 6 zugleich eine Bewegung der Kabine 1 nach oben als auch eine Bewegung der Kabine 1 nach unten verhindert. Die um halbe Zahnteilung vertikal gegen eine geringe Federkraft der Federelemente 7 verschiebbare Riegelplatte sorgt für einen sicheren Eingriff. Der Motor zum Antrieb der Kabine 1 wird nun strom- und somit kraftlos und die vertikale Lage der Riegelplatte 6 stellt sich lastabhängig ein. Somit ist eine sichere Haltekraft in beiden Fahrrichtungen gewährleistet. Also wird mit einem einzigen beweglichen Teil zugleich eine Bewegung der Kabine nach oben als auch nach unten verhindert. Vor dem Wegfahren baut der Motor die Treibkraft in Abhängigkeit von der vertikalen Lage der Riegelplatte 6 auf. Die Riegelplatte 6 wird mittels des Stellglieds 5 elektrisch gelüftet. An elevator drive connected directly to car 1 requires a holding brake 4, which the braking forces 1: 1 should bring up. In normal operation, cabin 1, motor driven or braked, on a Target floor driven. When cabin 1 is stationary, this will be Actuator 5 switched off and the toothed Locking plate 6 moves into the by means of the compression springs 8 interlocking crossbar 4.2. The holding brake 4 is therefore the cabin 1 without positive interlocking with the crossbar 4.2 lock. Thus, with a single locking plate 6 at the same time a movement of the cabin 1 upwards as well as one Movement of cabin 1 down is prevented. The half Tooth pitch vertically against a low spring force Spring elements 7 slidable locking plate ensures a safe intervention. The motor for driving the cabin 1 is now without power and thus without power and the vertical position of the Locking plate 6 adjusts itself depending on the load. So is one secure holding force guaranteed in both directions. So with a single moving part it becomes one at the same time Movement of the cabin up and down prevented. The engine builds the driving force before driving away depending on the vertical position of the locking plate 6 on. The locking plate 6 is by means of the actuator 5th electrically ventilated.

    Bei einem Notstop oder beim Öffnen des Sicherheitskreises des Aufzugs ist das Funktionsprinzip der Bremseinrichtung gleich wie oben, jedoch ausserhalb des Stockwerks.In the event of an emergency stop or when opening the safety circuit of the elevator is the functional principle of the braking device same as above, but outside the floor.

    Bei einer formschlüssigen Bremse benötigt man ca. 1/1000 der Anpresskraft der Bremsbacken, anderseits bedingt der formschlüssige Eingriff einen ca. 10-fachen Bremsriegel-Hub, um eine ausreichende Überdeckung zu erreichen. Die mechanische Arbeit zum Bewegen der Bremseinrichtung (Arbeit = Kraft * Weg) wird somit um den Faktor 0.01 kleiner und unter der Annahme von gleichen Betätigungszeiten somit auch die mechanische Leistung zum Lüften der Bremsriegel entsprechend reduziert.With a positive brake you need about 1/1000 of the Contact pressure of the brake shoes, on the other hand, the positive engagement an approx. 10-fold brake bolt stroke, to achieve sufficient coverage. The mechanical work for moving the braking device (Work = force * path) is therefore smaller by a factor of 0.01 and thus assuming the same operating times also the mechanical performance for releasing the brake bolts reduced accordingly.

    Der Formschluss zwischen beweglichem und feststehendem Teil kann, wie oben beschrieben, mittels einer verzahnten Riegelplatte gegen einen Zahnriemen aufgebracht werden oder optional mittels eines Riegels mit einer Spitzverzahnung, die in ein Gummiband eindringbar ist.The positive connection between the moving and fixed part can, as described above, by means of a toothed Locking plate can be applied against a toothed belt or optionally with a bolt with serration, which can be penetrated into a rubber band.

    Die Bremseinrichtung gemäss der Erfindung ist sowohl für Aufzüge mit Linearantrieb als auch für andere Antriebskonzepte verwendbar. Die Bremseinrichtung kann beispielsweise auch mit einem Treibscheibenaufzug, oder in Kombination mit einem auf der Kabine oder auf dem Gegengewicht mitfahrenden Antrieb anwendbar sein. Die Anordnung ist dabei grundsätzlich gleich: der bewegliche Teil/Riegel ist auf der Kabine mitfahrend und der feststehende Teil/Gegenstück auf der ganzen Fahrbahnlänge, beispielsweise an der Führung, Schachtwand, Tragkonstruktion etc, montiert. The braking device according to the invention is both for Lifts with linear drives as well as others Drive concepts can be used. The braking device can for example with a traction sheave elevator, or in Combination with one on the cabin or on the The counterweight traveling drive can be used. The The arrangement is basically the same: the movable one Part / bolt is moving on the cabin and the fixed part / counterpart along the entire length of the road, for example on the guide, shaft wall, supporting structure etc, assembled.

    Bei einer reinen Nutzung als Haltebremse auf Etagenhöhe kann das Gegenstück 4.2 der Riegelplatte 6 im Türfrontbereich integriert werden. Die Kosten würden weiter sinken.With a pure use as a holding brake at floor level the counterpart 4.2 of the locking plate 6 in the door front area to get integrated. The costs would decrease further.

    Die Bremseinrichtung könnte auch an einer rotierenden Treibscheibe oder an einer rotierenden Welle des Motors angeordnet werden. In diesem Fall ist die Treibscheibe oder die Welle des Motors mit einer Verzahnung versehen, in die im Bremszustand eine entsprechend komplementäre Verzahnung einer feststehenden Bremsbacke formschlüssig eingreifen kann. The braking device could also be rotating Traction sheave or on a rotating shaft of the motor to be ordered. In this case the traction sheave is or provide the shaft of the motor with a toothing into which a corresponding complementary toothing in the braking state intervene with a fixed brake shoe can.
