Abstract
Description
Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig, gemäß dem Oberbegriff von Anspruch 1.The invention relates to an escalator or moving walk, according to the preamble of claim 1.
Fahrtreppen und Fahrsteige weisen Spannketten auf, an denen Stufenbänder bzw. Palettenbänder umlaufen. Die Spannketten sind zwar ausgesprochen solide und mit genügenden Sicherheitsreserven dimensioniert ausgelegt, jedoch unterliegen sie einem Verschleiß, der zur Längung der Ketten führt.Escalators and moving walks have tensioning chains on which step belts or pallet belts circulate. Although the clamping chains are extremely solid and dimensioned with sufficient safety reserves, they are subject to wear that leads to elongation of the chains.
Es sind allgemein Kettenspannvorrichtungen bekannt, die im Umlenkbereich von Fahrtreppen und Fahrsteigen eingebaut werden, um die Kette auch bei einer unerwünschten Längung im gespannten Zustand zu halten und somit verhindern sollen, dass die Kette von den Kettenrädern abspringt und infolgedessen, dass eine Kollision von Stufen bzw. von Stufeneinlaufteilen auftritt.There are generally known chain tensioning devices, which are installed in the deflection of escalators and moving walks to keep the chain even with an undesirable elongation in the tensioned state and thus to prevent the chain from jumping off the sprockets and consequently that a collision of stages or ., occurs by step inlet parts.
Es ist seit recht langer Zeit bekannt geworden, Sicherheitsschalter einzusetzen, die die Fahrtreppe, beim Überschreiten einer vorgegebenen Längung, abschalten sollen.It has been known for quite some time to use safety switches that should shut off the escalator when exceeding a predetermined lengthening.
Eine solche Fahrtreppe ist aus der
Aus
Die bisher bekannten Fahrtreppen und Fahrsteige weisen jedoch alle den Nachteil auf, dass die Spannstation am Traggerüst aufgenommen und ausgerichtet wird. Es werden auch zusätzliche seitlich angeordnete Bauteile zur Abstützung und Führung der Spannstation bei den bisher bekannten Lösungen benötigt. Dies führt zu einem erhöhten Materialaufwand und einer zeit- und kostenaufwendigen Montage.However, the previously known escalators and moving walks all have the disadvantage that the tensioning station is received and aligned on the support frame. It also requires additional laterally arranged components for supporting and guiding the tensioning station in the previously known solutions. This leads to an increased cost of materials and a time-consuming and costly installation.
Die Hersteller von Fahrtreppen und Fahrsteige sind aber ständig bemüht, die Kosten nicht nur für die Montage solcher, sondern auch für die Fertigung von Fahrtreppen und Fahrsteigen zu reduzieren. Des Weiteren erfordert der Wettbewerb eine kurze Lieferzeit von Fahrtreppen und Fahrsteige und somit - eine möglichst rasche Herstellung.The manufacturers of escalators and moving walks are constantly striving to reduce costs not only for the installation of such, but also for the production of escalators and moving walks. Furthermore, the competition requires a short delivery time of escalators and moving walks and thus - the fastest possible production.
Daher liegt der Erfindung die Aufgabe zugrunde, eine Fahrtreppe oder einen Fahrsteig gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die bzw. der mit möglichst geringem Fertigungsaufwand und kostengünstig hergestellt werden kann, bei einer vereinfachten Montage.The invention is therefore an object of the invention to provide an escalator or a moving walk according to the preamble of claim 1, which or can be produced with the least possible manufacturing effort and cost, with a simplified installation.
Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by claim 1. Advantageous developments emerge from the subclaims.
Ein wesentlicher Punkt der Erfindung besteht darin, die Spannstation in Führungssystembauelemente zu integrieren und somit den Aufwand durch die Reduzierung von Materialeinsatz und Ausrichtarbeiten zu senken.An essential point of the invention is to integrate the tensioning station in guide system components and thus reduce the effort by reducing the use of material and alignment work.
Erfindungsgemäß besonders günstig ist es, dass im Umlenkbereich der Fahrtreppe oder des Fahrsteigs, die Kettenrollenschienen im Umlenkbereich federnd zur Aufrechterhaltung der Kettenspannung geführt sind. Dabei sind die Schlepprollenschienen fest und daher nicht beweglich an Schienenbauelemente, wie Seitenbleche, die mit dem Rahmen der Fahrtreppe bzw. des Fahrsteigs verbunden werden, angebracht. Die Kettenrollenschienen und damit die Lauffläche der Kettenrollen werden zwischen einem rahmenfesten Seitenteil und den Schlepprollenschienen zum Spannen der Kette beweglich ausgeführt.According to the invention it is particularly favorable that in the deflection of the escalator or the moving walk, the chain roller rails are resiliently guided in the deflection area to maintain the chain tension. The towing roller rails are fixed and therefore not movable to rail components, such as side panels, which are connected to the frame of the escalator or the moving walk attached. The chain roller rails and thus the running surface of the chain rollers are designed to be movable between a frame-fixed side part and the drag roller rails for tensioning the chain.
Durch die federnde Ausbildung der Kettenrollenschienen wird erreicht, dass bei einer auftretenden Stufenkettenlängung bzw. Palettenkettenlängung, ein Nachspannen der Ketten auf einfache und Platz sparende Weise realisierbar ist. Die Spannstation, mit der die Kettenrollenschienen in Verbindung stehen, ist in seitliche Bauelemente, über welche die Schienen der Fahrtreppe bzw. des Fahrsteigs mit dem Rahmen der Fahrtreppe oder des Fahrsteigs verbunden sind, integriert, was zu einer wesentlichen Reduzierung von Materialeinsatz führt.Due to the resilient design of the chain roller rails it is achieved that, in the event of a step chain elongation or pallet chain elongation, the chains can be re-tensioned in a simple and space-saving manner. The tensioning station, with which the chain roller rails are connected, is integrated into lateral components, via which the rails of the escalator or of the moving walkway are connected to the frame of the escalator or moving walk, which leads to a substantial reduction of material usage.
Dadurch, dass erfindungsgemäß nur die Kettenrollenschienen zum Spannen beweglich ausgeführt werden und die Schlepprollenschienen fest mit an den Rahmen der Fahrtreppe bzw. des Fahrsteigs angebrachten Schienenbauelementen, wie Seitenbleche, verbunden werden, weisen die Schlepprollenschienen keine Unterbrechung auf, die die Laufruhe und Sicherheit beeinträchtigen könnte.Due to the fact that according to the invention only the chain roller rails are designed to be movable and the track roller rails firmly connected to the frame of the escalator or the moving walk rail components, such as side panels, the tow rails have no interruption, which could affect the smoothness and safety.
Vorzugsweise sind die Kettenrollenschienen mit Bauelementen einer Spannstation, welche schiebebeweglich gegenüber dem Rahmen der Fahrtreppe oder des Fahrsteigs gelagert ist, verbunden. Die Gewichts- und die Spannkräfte sowie die horizontalen und vertikalen Führungskräfte zur Ausrichtung der Spannstation werden durch die seitlichen Bauelemente der Schienen, in denen die Spannstation integriert ist, übernommen.Preferably, the chain roller rails with components of a tensioning station, which is slidingly mounted relative to the frame of the escalator or the moving walk, connected. The weight and clamping forces as well as the horizontal and vertical guide forces for aligning the tensioning station are taken over by the lateral components of the rails in which the tensioning station is integrated.
Vorzugsweise ist die Spannstation über ein Lager, insbesondere ein Gleitlager, an dem rahmenfesten Seitenteil gelagert. Das Gleitlager ist dabei an eine für die Spannstation in dem rahmenfesten Seitenteil vorgesehene Ausnehmung angebracht, was für die kompakte Ausführung der Spannstation sorgt.Preferably, the clamping station via a bearing, in particular a plain bearing, mounted on the frame-fixed side part. The plain bearing is attached to a provided for the tensioning station in the frame-fixed side part recess, which ensures the compact design of the tensioning station.
Besonders günstig ist es, dass die Spannstation derart ausgebildet ist, dass sie einen Rahmen aufweist, der auf dem Gleitlager angebracht ist, und mit welchem die Spannfeder und ein Sicherheitsschalter, insbesondere ein Schaltnocken-Schalter, zur Überwachung von Stufenkettenlängung bzw. Palettenkettenlängung in Verbindung stehen.It is particularly favorable that the clamping station is designed such that it has a frame which is mounted on the slide bearing, and with which the tension spring and a safety switch, in particular a switching cam switch, for monitoring step chain elongation or pallet chain elongation in connection ,
Vorzugsweise ist der Sicherheitsschalter zur Überwachung der Stufenkettenlängung bzw. der Paiettenketteniängung auf den Rahmen der Spannstation gelagert, so dass er bei einem Nachspannen der Ketten mit verschoben wird. Dadurch entfällt das nachträgliche Anpassen der Schalterposition.Preferably, the safety switch for monitoring the step chain elongation or the Paiettenketteniängung is mounted on the frame of the tensioning station, so that it is moved with a retightening of the chains. This eliminates the subsequent adjustment of the switch position.
Vorteilhafterweise weist die Spannstation ein Seitenteil auf, auf dem die Kettenrollenschiene angebracht ist, wobei das Seitenteil mit dem Rahmen der Spannstation fest verbunden ist. Somit wird beim Einstellen der Spannkraft der Spannfeder sowohl das Seitenteil der Spannstation als auch die mit ihm verbundene Kettenrollenschiene mit verschoben, um die Ketten bei einer auftretenden Längung nachzuspannen.Advantageously, the tensioning station on a side part on which the chain roller rail is mounted, wherein the side part is fixedly connected to the frame of the tensioning station. Thus, when adjusting the clamping force of the tension spring, both the side part of the tensioning station and the chain roller rail connected to it are also displaced in order to retighten the chains when an elongation occurs.
Vorzugsweise ist die Kettenrollenschiene mit seitlich angebrachten Zapfen versehen, welche zur Positionierung der Kettenrollenschiene auf dem Seitenteil der Spannstation vorgesehen sind. Das Seitenteil der Spannstation weist korrespondierende Aussparungen auf, in denen die Zapfen bei dem Anbringen der Kettenrollenschiene an dem Seitenteil eingreifen. Somit wird auf einfache Weise die Montage der beweglichen Kettenrollenschiene und die Verbindung der Kettenrollenschiene mit der Spannstation realisiert.Preferably, the chain roller rail is provided with laterally mounted pins, which are provided for positioning the chain roller rail on the side part of the tensioning station. The side part of the clamping station has corresponding recesses in which engage the pins in the attachment of the chain roller rail on the side part. Thus, the assembly of the movable chain roller rail and the connection of the chain roller rail is realized with the tensioning station in a simple manner.
Gemäß einer weiteren, ebenfalls günstigen Ausgestaltung werden die Bauelemente der Spannstation unlösbar miteinander verbunden und vorzugsweise durch Laserschweißen gefügt. Die Formgebung der Einzelteile erfolgt vorzugsweise durch Laserschneiden.According to another, likewise favorable embodiment, the components of the tensioning station are permanently connected to each other and preferably joined by laser welding. The shaping of the individual parts is preferably carried out by laser cutting.
