Description

Die Erfindung betrifft eine Sicherheitseinrichtung für Personenförderanlagen, insbesondere für Rolltreppen und Rollsteige mit mindestens einer Kammplatte, welche bei einer, ein zulässiges Mass übersteigender Krafteinwirkung in horizontaler oder vertikaler Richtung über entsprechende Mittel einen Sicherheitsschalter betätigt.The invention relates to a safety device for Passenger conveyors, especially for escalators and Moving walks with at least one comb plate, which a permissible level of excessive force in horizontal or vertical direction via corresponding Activated by a safety switch.

Aufgrund entsprechender US-Vorschriften (ASME A17.1/Rule 805.1) muss eine Rolltreppe oder ein Rollsteig über einen Sicherheitsschalter stillgesetzt werden, wenn infolge eines Hindernisses eine horizontale Krafteinwirkung auf die Kammplatte einen Wert von 500 N oder eine vertikale Krafteinwirkung auf die Kammplatte einen Wert von 668 N je pro Seite übersteigt.Due to corresponding US regulations (ASME A17.1 / Rule 805.1) an escalator or escalator must go over one Safety switches are shut down if as a result of a A horizontal force on the obstacle Comb plate a value of 500 N or a vertical one Force on the comb plate a value of 668 N each per page.

Diese Vorschrift hat zur Folge, dass bestehende Sicherheitseinrichtungen dahingehend ergänzt werden müssen und dass neue Konstruktionen von Sicherheitseinrichtungen bereits vorschriftskonform ausgeführt sind.This regulation means that existing Security devices must be supplemented accordingly and that new designs of safety devices have already been carried out in accordance with regulations.

Die EP-Anmeldung Nr. 0 621 226 beschreibt und zeigt eine Sicherheitseinrichtung, mittels welcher die Betätigung eines Sicherheitsschalters in horizontaler und vertikaler Richtung möglich ist. Eine horizontal fest eingebaute Auslöseeinrichtung mit Druckfeder, Druckbolzen und nachfolgendem Sicherheitsschalter wird von einer auf Rollen gelagerten Kammplatte bei horizontaler und bei vertikaler Kammplattenbewegung betätigt. Als Zwischenglied zwischen Kammplatte und Auslöseeinrichtung ist ein beweglicher Winkelhebel vorhanden. Bei einer Bewegung der Kammplatte in horizontaler Richtung erfolgt die Auslösung ohne Mitfunktion des Winkelhebels, obwohl dessen vertikaler Schenkel als Zwischenlage die Bewegung mitmacht. Bei einer vertikalen Bewegung der Kammplatte besteht die Funktion des Winkelhebels darin, diese vertikale Bewegung in eine horizontale Bewegung umzusetzen. Die Auslösewege sind mittels Stellschrauben und die Auslösekraft ist mittels veränderbarer Federspannung einstellbar. Das Verhältnis der horizontalen zur vertikalen Auslösekraft ist allein durch die geometrischen Abmessungen bzw. durch die Hebelarmlängen des vertikalen und des horizontalen Schenkels des Winkelhebels gegeben. Zusätzlich zu dieser Auslöseeinrichtung ist der Vorderteil der Kammplatte etwas beweglich ausgebildet und kann bei entsprechender Krafteinwirkung in vertikaler Richtung einen signalerzeugenden Druckschlauch betätigen.EP Application No. 0 621 226 describes and shows one Safety device by means of which the actuation of a Safety switch in horizontal and vertical directions is possible. A permanently installed horizontally Release device with pressure spring, pressure pin and subsequent safety switch is made by one on rollers mounted comb plate for horizontal and vertical Comb plate movement actuated. As an intermediate link between Comb plate and release device is a movable one Angle lever available. When the comb plate moves in in the horizontal direction, it is triggered without any co-function of the angle lever, although its vertical leg as Liner joins the movement. With a vertical Movement of the comb plate is the function of the angle lever in converting this vertical movement into a horizontal movement to implement. The release paths are by means of set screws and the release force is by means of variable spring tension adjustable. The ratio of the horizontal to the vertical The release force is due to the geometric dimensions alone or by the lever arm lengths of the vertical and given horizontal leg of the angle lever. In addition to this release device is the front part of the Comb plate is somewhat flexible and can be used corresponding force in the vertical direction Actuate pressure generating hose.

Das nicht veränderbare feste Verhältnis von horizontaler zu vertikaler Auslösekraft wird als einschränkend empfunden. Die indirekte Übertragung der vertikalen Kammplattenbewegung zur Auslöseeinrichtung über einen Winkelhebel ist mit zusätzlicher Reibung verbunden und kann, auch infolge von Abnützung, die Reproduzierbarkeit der Auslösekraft in vertikaler, aber auch in horizontaler Richtung nachteilig beeinflussen.The unchangeable fixed ratio of horizontal to vertical release force is perceived as restrictive. The indirect transmission of the vertical comb plate movement for Tripping device via an angle lever is included additional friction connected and can, also as a result of Wear, the reproducibility of the release force in vertical, but also disadvantageous in the horizontal direction influence.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Sicherheitseinrichtung für eine Rolltreppe oder einen Rollsteig zu schaffen, welche die genannten Nachteile nicht aufweist und insbesondere eine individuelle Festlegung der horizontalen und vertikalen Auslösekraft ermöglicht.It is therefore the object of the present invention, a Safety device for an escalator or one To create a moving walkway which does not have the disadvantages mentioned has and in particular an individual determination of allows horizontal and vertical release force.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnete und in Zeichnungen und Beschreibung dargestellte Erfindung gelöst.This object is characterized by that in claim 1 and invention shown in drawings and description solved.

Die Erfindung zeichnet sich u.a. dadurch aus, dass das Verhältnis von horizontaler zu vertikaler Auslösekraft ohne konstruktiven Eingriff veränderbar ist.The invention is characterized inter alia by in that the Ratio of horizontal to vertical release force without constructive intervention is changeable.

Vorteilhaft Weiterbildungen und Verbesserungen sind in den Unteransprüchen aufgeführt.Advantageous further training and improvements are in the Subclaims listed.

Eine verstellbare Lage der die Auslösekraft bestimmenden Feder dient der Wahl des Verhältnisses von horizontaler zu vertikaler Auslösekraft. An adjustable position of the triggering force Spring is used to choose the ratio of horizontal to vertical release force.

Die gewählte Federlage ist durch eine Rastriereinrichtung gesichert.The selected spring position is through a locking device secured.

Die Auslösekraftübertragung von der Kammplatte zu der Auslöseeinrichtung ist unmittelbar.The release force transmission from the comb plate to the Tripping device is immediate.

Gleitbolzen sind als Drehpunkte ausgebildet.Slide pins are designed as pivot points.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert und in den Zeichnungen dargestellt, es zeigen:

  • Fig.1 einen Querschnitt der Einrichtung in Längsrichtung und
  • Fig.2 einen Querschnitt der Einrichtung in Querrichtung.
    • The invention is explained in more detail below using an exemplary embodiment and illustrated in the drawings, in which:
  • 1 shows a cross section of the device in the longitudinal direction and
  • 2 shows a cross section of the device in the transverse direction.

    • In der Fig.1 ist eine Kammplatte mit 1 bezeichnet und gleitbar mittels vorderen Gleitbolzen 17 und hinteren Drehgleitbolzen 3 auf einer Tragplatte 2 angeordnet. Ein mit der Kammplatte fest verbundener Anschlagteil 4 weist beidseitig eines Federbolzens zwei parallele und vertikal gerichtete Schenkel 11 in der Form von Kreisringsegmenten auf, deren obere kreisbogenförmige Ränder über einen Winkel von ca 45° sich erstreckenden Bereich je eine zusammenhängende Folge gleichartiger etwa halbrunder Einkerbungen 12 aufweisen. Der Federbolzen 15 ist an einem mit der Grundplatte 2 fest verbundenen Achsbolzen 8 schwenkbar gelagert und trägt eine Feder 5 welche zwischen einer oberen Druckscheibe 18 und einer unteren Druckscheibe 14 eingespannt ist und mittels einer Einstellmutter 19 auf verschiedene Längen für verschiedenen Auslösekräfte eingestellt werden kann. Die untere Druckscheibe 14 ist als Rand mit grösserem Durchmesser einer auf dem Federbolzen 15 verschieblichen Hülse ausgebildet, welche unterhalb der Druckscheibe 18 seitlich je einen eingepressten Rastbolzen 13 aufweist.In Figure 1, a comb plate is designated 1 and slidable by means of front sliding pin 17 and rear Rotary sliding pin 3 arranged on a support plate 2. A with the comb plate has fixed stop part 4 on both sides of a spring bolt two parallel and vertical directed leg 11 in the form of circular ring segments on, whose upper circular edges over an angle a range of approx. 45 ° each contiguous sequence of similar semicircular Have notches 12. The spring bolt 15 is on one with the base plate 2 fixed axle bolts 8 pivotally mounted and carries a spring 5 which between an upper thrust washer 18 and a lower thrust washer 14 is clamped and by means of an adjusting nut 19 different lengths for different triggering forces can be adjusted. The lower thrust washer 14 is as Edge with a larger diameter on the spring bolt 15 movable sleeve formed, which below the Thrust washer 18 has a pressed-in locking pin 13 on each side having.

    Am Achsbolzen 8 ist ferner noch ein Schalthebel 6 schwenkbar gelagert. Der Schalthebel 6 weist einen nach links bis zu einem mit der Tragplatte 2 fest verbundenen Sicherheitsschalter 10 sich erstreckenden Schenkel auf, dessen Ende als Schaltkurve etwas schräg nach oben gebogen ist und bei einer Abwärtsbewegung den Rollenhebel des Sicherheitsschalters 10 betätigt. Über dem Zentrum des Achsbolzen 8 weist der Schalthebel 6 einen kurzen nach rechts sich fortsetzenden Schenkel auf, der an seinem Ende über einen Mitnehmerbolzen 16 mit einer schrägen Fläche des Anschlagteils 4 verbunden ist. Der Mitnehmerbolzen 16 weist eine Druckfeder 7 auf, die unter Krafteinwirkung eine Verminderung der Distanz zwischen kurzem Schenkel des Schalthebels 6 und dem Anschlagteil 4 ermöglicht. Der Hauptzweck der Feder 7 und der Mutter 22 besteht jedoch darin, dass beim Nachlassen einer äusseren Krafteinwirkung eine Rückstelleung des Schalthebels 6 in seine Ausgangsstellung erfolgen kann.A shift lever 6 can also be pivoted on the axle pin 8 stored. The shift lever 6 has one to the left one firmly connected to the support plate 2 Safety switch 10 extending leg on the end of which is bent slightly upwards as a switching curve is and with a downward movement the roller lever of the Safety switch 10 actuated. Over the center of the Axle pin 8, the shift lever 6 has a short to the right continuing thighs that over at its end a driving pin 16 with an inclined surface of the Stop part 4 is connected. The driving pin 16 has a compression spring 7, the one under the action of force Reduction of the distance between the short leg of the Switch lever 6 and the stop part 4 allows. The The main purpose of the spring 7 and the nut 22 is, however in the fact that when an external force is released a reset of the shift lever 6 in his Starting position can take place.

    Anschlagschrauben 9 sind je seitlich der Kammplatte 1 angeordnet und begrenzen deren vertikalen Weg nach oben bei Anhebung durch vertikale Krafteinwirkung.Stop screws 9 are on either side of the comb plate 1 arranged and limit their vertical path upwards Raised by vertical force.

    Die Achse des Federbolzens 15 entspricht der Wirkungsachse der Feder 5 und und weist in der gezeigten Lage einen Winkel Alpha zur Horizontalen auf.The axis of the spring bolt 15 corresponds to the axis of action the spring 5 and and has an angle in the position shown Alpha to the horizontal.

    In der Fig.2 sind die beiden parallel angeordneten Schenkel 11 in der Vorderansicht mit den Rastkerben 12 ersichtlich, sowie der Achsbolzen 8, welcher in einem mit der Tragplatte 2 fest verbundenen Haltebügel 21 gelagert ist. Mit 20 bezeichnet ist ferner noch ein Stück einer Stufe dargestellt.In Figure 2, the two legs are arranged in parallel 11 can be seen in the front view with the notches 12, and the axle pin 8, which in one with the support plate 2nd firmly connected bracket 21 is mounted. At 20 designated a piece of a stage is also shown.

    Als Fig.3 ist, fluchtend mit der Wirkungsachse der Feder 5 ein Kräfteparallelogramm dargestellt, dessen Diagonale die statische Kraft F in der Wirkungsachse der Feder 5 bedeutet. Die Kraft F entspricht der mittels der Einstellmutter eingestellten Vorspannung der Feder 5. In der gezeigten Lage weist die Wirkungsachse der Feder 5, aufgrund der Lage in der Rastkerben, einen positiven Winkel Alpha zur Horizontalen auf. 3 is in alignment with the axis of action of the spring 5 a parallelogram of forces is shown, the diagonal of which static force F in the axis of action of the spring 5 means. The force F corresponds to that using the adjusting nut set preload of the spring 5. In the position shown has the axis of action of the spring 5, due to the location in the Notches, a positive angle alpha to the horizontal on.

    Mittels der Einstellmutter 19 wird die obere Druckscheibe 18 gegen die Feder 5 gedrückt und hiermit durch Anziehen und Lösen die statische Kraft F eingestellt. Mit der eingestellten Kraft F unter dem Winkel Alpha wird die Kammplatte 1 bzw. die Hinterseite des Schenkels 11 an den Achsbolzen 8 angeschlagen. Entsteht durch äussere Krafteinwirkung auf die Kammplatte 1 eine Kraft die grösser ist als die resultierende Kraft F, so wird der Schenkel 11 vom Achsbolzen 8 weggestossen und über den Mitnehmerbolzen 16 der Schalthebel 6 mitgenommen, was eine Betätigung des Sicherheitsschalters 10 durch linken langen Schenkel des Schalthebels 6 zur Folge hat.By means of the adjusting nut 19, the upper thrust washer 18 pressed against the spring 5 and hereby by tightening and Release the static force F set. With the set force F under the angle alpha becomes the Comb plate 1 or the rear of the leg 11 to the Axle pin 8 struck. Arises from the outside Force action on the comb plate 1 a force that is greater as the resulting force F, the leg 11 becomes pushed away from the axle pin 8 and over the driver pin 16 the shift lever 6 entrained what an actuation of the Safety switch 10 by the left long leg of the Shift lever 6 has the consequence.

    Die statische Kraft F kann in die horizontale Komponente Fh und in die vertikale Komponente Fv zerlegt werden. In der eingestellten Lage der Wirkungsachse der Feder 5 beträgt der Winkel Alpha ca 60° zur Horizontalen. Bei dieser gezeigten Lage der Feder 5 ist bei einer grafischen Auswertung des Kräfteparallelogramms ersichtlich, dass für eine Betätigung des Sicherheitsschalters 10 in horizontaler Richtung etwa die Hälfte der Kraft F, was Fh entspricht, zu überwinden ist, und dass für die Betätigung des Sicherheitsschalters 10 in vertikaler Richtung eine viel grössere Kraft, fast 90% von F, was der Kraft Fv entspricht, zu überwinden ist. Das statische Verhältnis von horizontaler Auslösekraft Fh zu vertikaler Auslösekraft Fv ist beim vorliegenden eingestellten Winkel Alpha etwa 1:1,75. Wird der Winkel Alpha durch Verstellen der Feder 5 auf den Rastkerben auf beispielweise 45° eingestellt, wird das Verhältnis logischerweise Fh:Fv = 1:1. Bei einem Einstellwinkel < 45° wechselt das Verhältnis in die Richtung Fh > Fv.The static force F can be divided into the horizontal component Fh and be broken down into the vertical component Fv. In the set position of the axis of action of the spring 5 is Alpha angle approx. 60 ° to the horizontal. In this shown Location of the spring 5 is in a graphical evaluation of the Force parallelogram shows that for an actuation of the safety switch 10 approximately in the horizontal direction Half of the force F, which corresponds to Fh, has to be overcome, and that for operating the safety switch 10 in vertical direction a much greater force, almost 90% of F, what corresponds to the force Fv has to be overcome. The static Ratio of horizontal release force Fh to vertical The release force Fv is at the set angle Alpha about 1: 1.75. If the angle alpha is adjusted by adjusting the Spring 5 on the notches set to 45 °, for example, the ratio logically becomes Fh: Fv = 1: 1. At a Setting angle <45 ° changes the ratio in the direction Fh> Fv.

    Als trigonometrische Formel ausgedrückt heisst es: F = Fh cosα Expressed as a trigonometric formula: F = Fh cos α

    Das Verstellen der Feder 5 in kleinen Winkelschritten auf den Rastkerben 12 ermöglicht eine beliebige Anpassung des Verhältnisses Fh:Fv. Somit kann, ohne jeglichen konstruktiven Eingriff in die Sicherheitseinrichtung, eine jederzeit sofortige Anpassung an veränderte äussere Verhältnisse oder an geänderte Vorschriften erfolgen. Bei entsprechender Ausbildung der Rastkerben 12 und des Rastbolzens 13 ist eine ruckweise Verstellung von Rastkerbe 12 zu Rastkerbe 12 ohne vorhergehende Entspannung der Feder 5 möglich, wobei gleichwohl eine sichere Haltung der Einstellung gewährleistet ist. Der Mitnehmerbolzen 16 weist ebenfalls Verstelleinrichtungen auf. Mit der Mutter oberhalb des Anschlagteiles 4 wird die Ausgangslage des Schalthebels 6 durch entsprechende Längenveränderung eingestellt. Mit einer zweiten Mutter an der Unterseite des Anschlagteils 4 wird eine Feder 7 vorgespannt. Mittels dieser Einrichtung wird einerseits der Schalthebel 6 zwangsläufig mitgenommen bei einer Kammplattenbewegung und anderseits ergibt sich so die Möglichkeit, zwecks Prüfung und Einstellung den Schalthebel 6 manuell zu betätigen ohne die Kammplatte 1 zu bewegen.The adjustment of the spring 5 in small angular steps on the Locking notches 12 allows any adjustment of the Ratio Fh: Fv. Thus, without any constructive Intervention in the safety device, one at any time immediate adaptation to changed external conditions or changed regulations. With appropriate Formation of the locking notches 12 and the locking bolt 13 is one jerky adjustment of notch 12 to notch 12 without previous relaxation of the spring 5 possible, wherein nevertheless ensures a safe attitude of the attitude is. The driving pin 16 also has Adjustment devices on. With the mother above the Stop part 4 becomes the starting position of the shift lever 6 adjusted by changing the length. With a second nut on the underside of the stop part 4 is a spring 7 biased. By means of this facility on the one hand, the shift lever 6 inevitably entrained a comb plate movement and on the other hand results in the Possibility of shift lever 6 for testing and adjustment to be operated manually without moving the comb plate 1.

    Wird die Kammplatte 1 durch vertikale Kräfte wie z.B. einem keilförmigen Fremdkörper in einer Stufenrille emporgedrückt, so kann sich die Kammplatte 1 bis zu einer durch Anschlagschrauben 9 einstellbaren Höhe heben und sich dabei um einen Drehpunkt, gegeben durch die Drehpunktgleitbolzen 3 um einen sehr kleinen Winkel drehen. Die Drehpunktgleitbolzen 3 weisen zu diesem Zwecke an ihren Stirnseiten halbkugelige Einlagen auf.Is the comb plate 1 by vertical forces such as one wedge-shaped foreign bodies pushed up in a step groove, so the comb plate 1 up to one Lift the stop screws 9 adjustable height while doing so around a pivot point, given by the pivot pin 3 rotate through a very small angle. The pivot pin 3 have hemispherical end faces for this purpose Deposits on.

    Die Sicherheitseinrichtung beschränkt sich in den konstruktiven Einzelheiten nicht auf das gezeigte Beispiel. Die Rastrierung der Feder 5 in einer bestimmten Lage kann auch mittels einer feinen Zähnung an der unteren Druckscheibe 14 und am kreisbogenförmigen Rand des Schenkels 11 ausgeführt werden. Eine weitere Verstellkonstruktion bestünde darin, auf der Seite der beiden Schenkel 11 je einen bogenförmigen Schlitz auszunehmen und die Federbolzen 15 mittels je eines Querbolzens mit Gewinde und Mutter stufenlos an beliebiger Lage festzusetzen. The safety device is limited to constructive details not on the example shown. The locking of the spring 5 in a certain position can also by means of fine perforation on the lower thrust washer 14 and on the circular arc-shaped edge of the leg 11 become. Another adjustment construction would consist of the side of the two legs 11 each have an arcuate shape Except slot and the spring pin 15 by means of one Cross bolt with thread and nut continuously on any To fix the situation.
