Description

Die Erfindung betrifft eine Sicherheitseinrichtung für Personenförderanlagen, insbesondere für Rolltreppen und Rollsteige.The invention relates to a safety device for passenger conveyor systems, in particular for escalators and moving walks.

Insbesondere im Hinblick auf die stetig strenger werdenden Anforderungen, die Sicherheitsmaßnahmen bei Personenförderanlagen, wie Rolltreppen und Rollsteigen, zu verbessern, sind die bisher bekannt gewordenen Sicherheitseinrichtungen nicht mehr als optimal anzusehen. Da neben Horizontalkräften auch Vertikalkräfte im Bereich der Kammsegmente sowie der Trägerplatte auftreten, die unterschiedlich feinfühlig zu einem Ansprechen der Notabschaltung führen müssen, erscheint hier eine Überarbeitung des St.d.T. geboten.Particularly with regard to the ever stricter requirements to improve the safety measures in passenger conveying systems, such as escalators and moving walks, the safety devices which have become known are no longer to be regarded as optimal. Since, in addition to horizontal forces, vertical forces also occur in the area of the comb segments and the support plate, which must respond to the emergency shutdown with different sensitivity, a revision of the St.d.T. appears here. commanded.

Ziel des Erfindungsgegenstandes ist es, eine Sicherheitseinrichtung für Personenförderanlagen, wie Rolltreppen und Rollsteige, dahingehend weiterzubilden, daß bei möglichst einfachem Aufbau die Sicherheit der die Personenförderanlage benutzenden Personen in optimaler Weise gewährleistet werden kann.The object of the invention is to develop a safety device for passenger conveyor systems, such as escalators and moving walks, in such a way that the safety of the people using the passenger conveyor system can be guaranteed in an optimal manner with the simplest possible structure.

Dieses Ziel wird erreicht durch eine Sicherheitseinrichtung für Personenförderanlagen, insbesondere für Rolltreppen und Rollsteige, mit mindestens einer Kammsegmente beinhaltenden Trägerplatte, die relativ zu mindestens einem sie aufnehmenden Trägerelement im wesentlichen horizontal verschiebbar und um eine horizontale Drehachse außerhalb der Kammsegmente schwenkbar ist, sowie mit mindestens einer den Antrieb der Personenförderanlage stillsetzenden Abschalteinrichtung zusammenwirkt.This goal is achieved by a safety device for passenger conveyor systems, in particular for escalators and moving walks, with a carrier plate containing at least one comb segment, which can be displaced substantially horizontally relative to at least one carrier element receiving it and can be pivoted about a horizontal axis of rotation outside the comb segments, and with at least one the drive of the passenger conveyor shutdown device cooperates.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the invention can be found in the subclaims.

Der Erfindungsgegenstand ermöglicht somit zwei voneinander unabhängige Abschaltmöglichkeiten der Personenförderanlage, die je nach Anforderung einzeln oder aber auch in Kombination zur Anwendung gelangen können. Zum einen ist im Bereich der Trägerplatte zwischen den Rollen der sie aufnehmenden Rollenträger eine Abschalteinrichtung vorgesehen, die über ein Hebelgestänge betätigt wird, und sowohl bei Horizontal- als auch bei von unten auf die Trägerplatte wirkenden Vertikalkräften anspricht. Zum anderen ist im Bereich zwischen den einzelnen Kammsegmenten und dem Endbereich der sie aufnehmenden Trägerplatte ein Druckwellenschlauch vorgesehen, wobei infolge der Schwenkbarkeit der einzelnen Kammsegmente um beispielsweise den Kopf einer Linsenschraube ein Druckwellenstoß innerhalb des Druckwellenschlauches herbeigeführt wird, der ebenfalls eine Notabschaltung des Antriebes der Personenförderanlage auslösen kann.The subject of the invention thus enables two mutually independent switch-off possibilities for the passenger conveyor system, which can be used individually or in combination depending on the requirement. On the one hand, a switch-off device is provided in the area of the carrier plate between the rollers of the roller carriers receiving it, which is actuated via a lever linkage and which responds to both horizontal and vertical forces acting on the carrier plate from below. On the other hand is in the area between the individual comb segments and the end area a pressure wave hose is provided in the carrier plate receiving it, whereby due to the pivotability of the individual comb segments around, for example, the head of a lens screw, a pressure wave shock is brought about within the pressure wave hose, which can also trigger an emergency shutdown of the drive of the passenger conveyor system.

Der Erfindungsgegenstand ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:

Figur 1
- Teilansicht einer Kammsegmente aufnehmenden Trägerplatte mit Abschalteinrichtung
Figur 2
- Schnitt durch den Endbereich der die Kammsegmente aufnehmenden Trägerplatte
Figur 3
- Schnitt durch den Auflagebereich der Trägerplatte auf dem zugehörigen Rollenträger
Figur 1 zeigt eine Trägerplatte 1 einer nicht weiter dargestellten Personenförderanlage, die in ihrem einen Endbereich 2 mit mehreren über ihre Breite verteilt angeordneten Kammsegmenten 3 bestückt ist, die mittels Schrauben 4 im Endbereich 2 verschraubt sind. Die Kammsegmente 3 wirken mit hier nur andeutungsweise dargestellten Stufen bzw. Paletten 5 der Personenförderanlage zusammen, die unter den Kammsegmenten 3 hindurchführbar sind. Unterhalb der Trägerplatte 1 ist seitlich jeweils ein als Rollenträger ausgebildetes Trägerelement 6 angeordnet mit beabstandeten Laufrollen 7,8 versehen ist. In der Trägerplatte 1 sind entsprechende Ausnehmungen 9 eingebracht, in welchen die jeweilige Laufrolle 8 eingreift. Die Abschalteinrichtung 26 ist zwischen den Laufrollen 7,8 vorgesehen. An der Trägerplatte 1 ist ein Bauteil 10 angeschraubt, an welchem ein Hebel 11 gelagert ist. Das freie Ende 12 des Hebels 11 ist an einer im Bereich des Rollenträgers 6 geführten Schaltstange 13 befestigt, deren freies Ende 14 wiederum mit dem Taster 15 einer Notabschalteinrichtung 16 zusammenwirkt. Die Schaltstange 13 ist hierbei mittels einer Druckfeder 17 auf einen vorgegebenen Ansprechwert vorgespannt. Zwischen den Kammsegmenten 3 und dem sie aufnehmenden Endbereich 2 der Trägerplatte 1 erstreckt sich ein im wesentlichen über die gesamte Breite der Kammträger 3 verlaufender Druckwellenschlauch 18, der ein weiteres feinfühliger ansprechendes Sicherheitsorgan darstellt. Die möglichen an der Trägerplatte 1 sowie den Kammsegmenten 3 auftretenden Kräfte sind durch Pfeile dargestellt und durch die entsprechenden Zeichen FH sowie FV bezeichnet. In Abhängigkeit von dem jeweiligen Kraftangriff wird entweder die mit den Kammsegmenten 3 verbundene Trägerplatte 1 in Richtung des Pfeiles 19 horizontal verschoben, wodurch der Hebel 11 parallel dazu ausgelenkt und über die Schaltstange 13 der Taster 15 und somit der Endschalter 16 betätigt wird. Bei von unten auftretenden Vertikalkräften im Bereich der Trägerplatte 1 wird dieselbe um die im freien Endbereich 25 gelegene Drehachse 20 geringfügig geschwenkt, wodurch ebenfalls eine Verlagerung des Hebels 11 mit entsprechender Betätigung des Endschalters 16 herbeigeführt wird. Bei feinfühligeren, unmittelbar im Bereich der Kammsegmente 3 auftretenden Vertikalkräften wird das einzelne oder mehrere Kammsegmente 3 um eine in einer anderen Figur dargestellte Achse geschwenkt und der Druckwellenschlauch 18 betätigt, was wiederum zu einer Notabschaltung des Antriebes der Personenförderanlage führt.The subject matter of the invention is illustrated in the drawing using an exemplary embodiment and is described as follows. Show it:
Figure 1
- Partial view of a comb plate receiving carrier plate with switch-off device
Figure 2
- Section through the end region of the carrier plate receiving the comb segments
Figure 3
- Section through the support area of the carrier plate on the associated roller carrier
Figure 1 shows a carrier plate 1 of a passenger conveyor system, not shown, which is equipped in its one end region 2 with several comb segments 3 distributed over its width, which are screwed by means of screws 4 in the end region 2. The comb segments 3 interact with steps or pallets 5 of the passenger conveyor system which are only indicated here and which can be passed under the comb segments 3. Below the carrier plate 1, a carrier element 6 designed as a roller carrier is arranged laterally and is provided with spaced-apart rollers 7, 8. Corresponding recesses 9 are made in the carrier plate 1, in which the respective roller 8 engages. The switch-off device 26 is provided between the rollers 7, 8. A component 10, on which a lever 11 is mounted, is screwed onto the carrier plate 1. The free end 12 of the lever 11 is attached to a shift rod 13 guided in the area of the roller carrier 6, the free end 14 of which in turn interacts with the button 15 of an emergency shutdown device 16. The shift rod 13 is biased by a compression spring 17 to a predetermined response value. Between the comb segments 3 and the end region 2 of the carrier plate 1 which receives them extends essentially over the entire width of the comb carriers 3 running pressure wave hose 18, which is another sensitive responsive security organ. The possible forces occurring on the carrier plate 1 and the comb segments 3 are represented by arrows and are designated by the corresponding characters F H and F V. Depending on the respective application of force, either the carrier plate 1 connected to the comb segments 3 is displaced horizontally in the direction of the arrow 19, as a result of which the lever 11 is deflected in parallel and actuated via the switching rod 13, the button 15 and thus the limit switch 16. In the event of vertical forces occurring from below in the region of the carrier plate 1, the latter is pivoted slightly about the axis of rotation 20 located in the free end region 25, which likewise causes the lever 11 to be displaced with the corresponding actuation of the limit switch 16. In the case of more sensitive vertical forces occurring directly in the area of the comb segments 3, the individual or more comb segments 3 are pivoted about an axis shown in another figure and the pressure wave hose 18 is actuated, which in turn leads to an emergency shutdown of the drive of the passenger conveyor system.

Figur 2 zeigt einen Längsschnitt durch den Endbereich 2 der Trägerplatte 1, in welchem die Kammsegmente 3 befestigt sind. Erkennbar ist der Druckwellenschlauch 18 sowie der durch eine Linsenkopfschraube 21 gebildete Drehpunkt 22 für das einzelne Kammsegment 3. Bei der angedeuteten Vertikalkraftkomponente werden einzelne oder mehrere Kammsegmente 3 in Pfeilrichtung um den Drehpunkt 22 geringfügig geschwenkt, was zu einer Anderung des Luftdruckes im Druckwellenschlauch 18 führt und schließlich die Notabschaltung des Antriebes der Personenförderanlage auslöst.FIG. 2 shows a longitudinal section through the end region 2 of the carrier plate 1, in which the comb segments 3 are fastened. The pressure wave hose 18 and the pivot point 22 formed by a pan head screw 21 for the individual comb segment 3 can be seen. In the indicated vertical force component, one or more comb segments 3 are pivoted slightly in the direction of the arrow around the pivot point 22, which leads to a change in the air pressure in the pressure wave hose 18 and finally triggers the emergency shutdown of the drive of the passenger conveyor system.

Figur 3 zeigt einen Längsschnitt durch den Auflagebereich der Trägerplatte 1 auf dem zugehörigen Rollenträger 6. Zwischen einem mit dem Rollenträger 6 verbunden Bolzen 23 und der Ausnehmung 9 in der Trägerplatte 1 erstreckt sich eine gleit- oder wälzgelagerte Laufrolle 8, auf welcher die Trägerplatte 1 in horizontaler Richtung verschiebbar geführt ist. Die seitliche Führung der Trägerplatte 1 wird hierbei durch Radialansätze 24 an der jeweiligen Laufrolle 8 herbeigeführt.FIG. 3 shows a longitudinal section through the contact area of the carrier plate 1 on the associated roller carrier 6. Between a bolt 23 connected to the roller carrier 6 and the recess 9 in the carrier plate 1, a slide or roller-bearing roller 8 extends, on which the carrier plate 1 in is guided horizontally. The lateral guidance of the carrier plate 1 is brought about by radial lugs 24 on the respective roller 8.
