Description

Die vorliegende Erfindung betrifft eine Einrichtung zur Begrenzung der Schwingungsamplituden von Tragmitteln und Ausgleichsmitteln bei einem Aufzug mit einem in Führungen laufenden Gegengewicht.The present invention relates to a device for Limitation of the vibration amplitudes of suspension elements and Compensatory means for an elevator with one in guides running counterweight.

Bei Aufzügen mit grossen Förderhöhen haben die Tragmittel und die Ausgleichsmittel die Tendenz, in horizontaler Richtung zu schwingen. Die Anregung zu diesen Schwingungen hat verschiedene Ursachen. Der Fahrbetrieb selbst ist eine der Hauptursachen. Beim periodischen Beschleunigen, Fahren mit grosser Geschwindigkeit und Verzögern entstehen, hervorgerufen durch kleine Abweichungen in der Vertikalen bei den Führungsschienen, kleine horizontale Bewegungskomponenten bei der Kabine und beim Gegengewicht. Diese horizontalen Bewegungkomponenten regen die Trag- und Ausgleichmittel zu horizontalen Schwingungen an, deren Auslenkung im Eigenresonanzbereich der Mittel so gross sein kann, dass gegenseitige Berührungen, wie auch Berührungen an Schachteinrichtungen auftreten, was zu Beschädigungen von Anlageteilen und Störungen des Fahrbetriebs führt.For elevators with large heads, the suspension means and the compensating means the tendency to go in the horizontal direction swing. The stimulus to these vibrations has different causes. The driving operation itself is one of the Main causes. With periodic acceleration, driving with great speed and deceleration arise, caused by small deviations in the vertical the guide rails, small horizontal movement components with the cabin and with the counterweight. This horizontal Movement components stimulate the suspension and compensation means horizontal vibrations, the deflection in Natural resonance range of the funds can be so large that mutual touches, as well as touches Chimney equipment occur, causing damage to Parts of the system and disruption of driving operations.

Es sind verschiedene Einrichtungen bekannt, welche das Entstehen solcher Schwingungen verhindern sollen.Various facilities are known which To prevent such vibrations from occurring.

Aus der US-Patentschrift Nr. 5,103,937 ist ein System zur Schwingungsbegrenzung von Aufzugsseilen bekannt, bei dem ein Begrenzungselement im Aufzugsschacht an der Schachtwand angeordnet ist. Dieses Element ist zwischen einer ausgestreckten und einer zurückgezogenen Stellung verschwenkbar. In der ausgestreckten Stellung begrenzt das Element die Schwingungamplituden der Seile. In der zurückgezogenen Stellung bleibt das Element ohne Wirkung auf die Seile. Die Verschwenkbarkeit ist notwendig, um die Kabine ungehindert passieren zu lassen. From U.S. Patent No. 5,103,937 is a system for Vibration limitation of elevator ropes is known in the case of a Boundary element in the elevator shaft on the shaft wall is arranged. This element is between one extended and retracted position pivotable. In the extended position, this limits Element the vibration amplitudes of the ropes. In the retracted position, the element remains ineffective the ropes. The swiveling is necessary to the cabin to let pass freely.

Die US-Patentschrift Nr. 4,117,908 zeigt eine Einrichtung, bestehend aus einem Schwingungsunterdrücker unter der Maschinenraumdecke im Schacht und einem weiteren auf der Kabine. Diese sind als rahmenartige Gebilde konstruiert und weisen Anschläge auf, welche nahe an Tragseile plaziert sind und einen mehr oder weniger grossen Abstand zur Kabinenoberseite bzw. zur Maschinenraumdecke aufweisen. Wenn Seilschwingungen auftreten, beispielsweise infolge Erdbeben, werden so die Schwingungen von der Kabine und von der Antriebsmaschine ferngehalten, jedoch selbst nicht wesentlich begrenzt. U.S. Patent No. 4,117,908 shows a device consisting of a vibration suppressor under the Engine room ceiling in the shaft and another on the Cabin. These are constructed as frame-like structures and have stops which are placed close to suspension cables and a more or less large distance from Have the top of the cabin or the engine room ceiling. If Rope vibrations occur, for example as a result of earthquakes, so the vibrations from the cabin and from the Drive engine kept away, but not essential itself limited.

Eine weitere Einrichtung ist aus der US-Patentschrift Nr. 3,666,051 bekannt. Hier sind mit der Kabine mitlaufende Seilführungen vorgesehen, welche beim Abwärtsfahren der Kabine in bestimmten Distanzen zueinander mittels Anschlägen an den Führungsschienen deponiert und beim Aufwärtsfahren durch die Kabine wieder eingeholt werden. Die Einrichtung ist bestimmt für eine Aufzugsanlage im Freien, wo mit starken Windeinflüssen zu rechnen ist. Für eine gebäudeinterne Anlage ist dieses Prinzip einerseits zu aufwendig und anderseits sind keine grossen Geschwindigkeiten realisierbar, weil das Deponieren und Einsammeln der Seilstabilisatoren schlagende Geräusche in der Kabine verursacht.Another device is known from US Pat. 3,666,051 known. Here are moving with the cabin Rope guides are provided, which when driving down the Cabin at certain distances from each other by means of stops deposited on the guide rails and when driving upwards be caught up by the cabin. The facility is Intended for an outdoor elevator system where strong Wind influences can be expected. For an internal system this principle is too complex on the one hand and on the other hand high speeds are not feasible because that Deposit and collect the rope stabilizers striking Causing noise in the cabin.

Bei beiden vorgehend genannten Beispielen wird die Schwingungsunterdrückung auf der Kabinenseite vorgenommen. Die der vorliegenden Erfindung zugrunde gelegte Überlegung ist jedoch die, dass auf der Kabinenseite grössere Schwingungsausschläge nötig sind als auf der Gegengewichtsseite, bis die Trag- und/oder Ausgleichsorgane an einem festen oder beweglichen Anlageteil anschlagen.In both of the above examples, the Vibration suppression made on the cabin side. The reasoning underlying the present invention is that the bigger one on the cabin side Vibration deflections are necessary than on the Counterweight side until the supporting and / or compensating elements attach to a fixed or movable part of the system.

Deshalb wurde der Erfindung die Aufgabe zugrunde gelegt, eine Einrichtung zur Begrenzung der Schwingungsamplituden von Trag- und Ausgleichsmittel auf der Gegengewichtsseite zu schaffen, die einfach und kostengünstig ist, jegliche Berührung der Trag- und/oder Ausgleichsmittel mit Anlageteilen verhindert und welche bei Extremausschlägen zusätzliche Sicherheit bietet.Therefore, the invention was based on the object Device for limiting the vibration amplitudes of Suspension and compensation means on the counterweight side too create that is simple and inexpensive, any Touching the suspension and / or compensating means with Prevents parts of the system and those with extreme rashes offers additional security.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This task is accomplished by the in the claims characterized invention solved.

Die Vorteile der Erfindung zeichnen sich u.a. dadurch aus, dass die Einrichtung mit statischen Mitteln ohne mechanisch bewegte Teile ausgeführt wird und dass auf der ganzen Förderhöhe ein Schutz vor grossen lateralen Ausschlägen der Trag- und Ausgleichsmittel wirksam ist. The advantages of the invention include by that the establishment with static means without mechanical moving parts is running and that all over Head protects against large lateral deflections of the Suspension and compensation means is effective.

Ein weiterer Vorteil liegt darin, dass bei Extremsituationen eine zusätzliche Sicherheitseinrichtung anspricht.Another advantage is that in extreme situations an additional safety device responds.

Ferner werden durch die erfindungsgemässe gegengewichtsseitige Schwingungsbegrenzung Berührungen von festen oder beweglichen Anlageteilen durch Tragmittel und insbesondere Ausgleichsmittel, ohne festmontierte Gegengewichtsumwehrung über die ganze Förderhöhe oder separaten Gegengewichtsschacht, vermieden. Das Gegengewicht ist für Revisions- und Kontrollarbeiten jederzeit frei zugänglich.Furthermore, according to the invention Vibration limitation on the counterweight side fixed or movable system parts by means of suspension elements and especially compensating means, without fixed Counterweight defense over the entire delivery head or separate counterweight shaft, avoided. The counterweight is free for revision and control work at any time accessible.

    Die Installation und die Funktion der erfindungsgemässen Einrichtung wird im folgenden beschrieben.The installation and the function of the invention Setup is described below.

    Der Begrenzungsrahmen 6 bildet mit allen in den Fig.2 und 3 dargestellten Teilen eine vollständige in sich abgeschlossene und vorfabrizierbare Baugruppe. Als anzupassende Dimensionen sind die Spurweite der Gegengewichtsschienen 3 und die Dicke des Gegengewichts 1 berücksichtigt. Pro Aufzugsanlage kann der Begrenzungsrahmen 9 in einem oder in mehreren Exemplaren installiert werden durch einfaches Anklemmen an den Führungsschienen 3 des Gegengewichtes 1. Die vertikale Distanz zwischen zwei Begrenzungsrahmen 9 wird, je nach Schwingungsanfälligkeit der Trag- bzw. Ausgleichsmittel 4 bzw. 5, beispielsweise Werte zwischen fünf bis zehn Meter aufweisen. Der unterste Begrenzungsrahmen wird möglichst nahe bei der unteren Umlenkschlaufe der Ausgleichsmittel 5 angebracht, weil dort die translatorischen Ausschläge der Ausgleichsmittel 5 am grössten sein werden.The bounding frame 6 forms with all in FIGS. 2 and 3 parts shown a complete self-contained and prefabricated assembly. As dimensions to be adjusted are the track width of the counterweight rails 3 and the thickness of counterweight 1 is taken into account. Per elevator system can the bounding frame 9 in one or more copies can be installed by simply connecting to the Guide rails 3 of the counterweight 1. The vertical Distance between two bounding frames 9, depending on Suspensibility of the suspension or compensation means 4 or 5, for example values between five and ten meters exhibit. The lowest bounding box is as close as possible in the lower deflection loop of the compensating means 5 attached because there the translational rashes of Compensatory 5 will be the largest.

    Bei mittleren translatorischen Ausschlägen der Trag- oder Ausgleichsmittel 4 oder 5 entsteht eine reibungsarme Berührung mit dem Begrenzungsrahmen 9 über die Rollen 7 oder 8. Werden die translatorischen Ausschläge so stark, dass die Berührung mit dem Begrenzungsrahmen 9 mit einer wesentlichen Aufprallkraft verbunden ist, wird ein Teil des Begrenzungsrahmens 9 mit seinem Rahmenendstücken 12 mehr oder weniger aus der Anschlagschulter 15 gezogen, was einen Überwachungskontakt 14 entlastet und dessen Kontakt öffnet. Dies hat die Unterbrechung des Sicherheitskreises und einen Notstop mit Ausserbetriebsetzung zur Folge. Ein solches Vorkommnis setzt eine grössere Störung voraus, wie z.B. Erdbeben oder defekte Teile an Ausgleichsmitteln 5 und rechtfertigt hiermit die sofortige Stillsetzung der Aufzugsanlage.With medium translational deflections of the support or Compensating means 4 or 5 creates a low-friction Contact with the bounding frame 9 via the rollers 7 or 8. Do the translational rashes become so strong that the Touch with the boundary frame 9 with an essential Impact force is connected to part of the Boundary frame 9 with its frame end pieces 12 more or less pulled from the stop shoulder 15, which one Monitoring contact 14 relieved and its contact opens. This has the interruption of the safety circuit and one Emergency stop with shutdown result. Such one Incident requires a major disruption, such as Earthquakes or defective parts on compensation means 5 and hereby justifies the immediate shutdown of the Elevator system.

    Anstelle der Rollen 7 und 8 kann das Rahmenprofil 9 bzw. dessen Querschnitt so ausgebildet sein, dass eine reibungsarme Oberfläche durch entsprechende Beschichtung und/oder dass eine sanft abweisende geometrische Form z.B. flaches Halbrund auf der Berührungsseite vorgesehen ist.Instead of the rollers 7 and 8, the frame profile 9 or whose cross section should be designed so that a low-friction surface due to appropriate coating and / or that a softly repellent geometric shape e.g. flat semicircle is provided on the contact side.
