Definitions
- the invention relates to a step substructure or pallet substructure for vehicles according to the preamble of claim 1, tread units, ie stages or pallets with such a step substructure or pallet substructure and driving devices with such tread units.
- Driving devices which may also be referred to as conveyors, are escalators and moving walks with a plurality of treading units, i. Steps or pavement pallets connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they walk on the kiting units in the same direction of movement as the ferry devices drive or move.
- the tread units form escalator steps, hereafter referred to as steps, and for ride surfaces, the tread units form pavement pallets, hereafter referred to as pallets.
- Escalators overcome with relatively large inclination greater differences in height as entire floors. Moving walkways, on the other hand, run horizontally or slightly at an angle, but generally with lower angles of inclination than escalators.
- Such driving devices include drive trains, which are designed as stepped or pallet chains. In the following, for the sake of simplicity, only drive trains are mentioned. These drive trains are driven to move the steps or pallets in the conveying direction, and they are according to the prior art at regular intervals with so-called step rollers or
- Pallet rollers (rollers, chain rollers) provided. These casters move or roll along dedicated rails. In the area of the ends of the driving devices, the drive trains run around the rollers around deflection wheels (for example sprockets) and thus make a change of direction. Instead of the tow rollers and sliding elements can be used.
- the sliding elements or rollers (rollers) are directly attached to a step or pallet chain, which serves as a drive train, as described above.
- step or pallet chains including the sliding or rolling elements attached thereto, two further rollers are required per step or pallet, which are referred to as drag rollers and roll along separate guide rails.
- stages or pallets have been relatively expensive to manufacture or pour and also expensive, since they must be very stable and torsionally rigid.
- the steps or pallets must be made very accurately in order to guarantee a safe, quiet, jerk-free run.
- An essential element of each step or pallet is the stepped substructure or pallet substructure, which has a solid, essential supporting function.
- the substructure must be very stable, stable, torsionally stiff and lightweight, which leads to high material costs and material use and processing costs and die-casting production costs.
- the pallet base consists of a frame of four metal angles, within which three Angle strips are provided. For steps, only the three angle strips are provided together with two step cheeks. These metal angles or angle strips are thick and therefore heavy.
- JP 08-245152 A are provided as a stepped base two cross members in the form of solid metal angle, which interact with step cheeks.
- the DD 69443 relates to a step for escalators, wherein the side cheeks are integrally connected to a front part.
- the front part is covered by a seat element.
- a tread plate On this angled element is a tread plate, which serves as a carrier for a tread element. Overall, so here is a lot of massive sheet metal used.
- An inventive step substructure (step support frame, step support frame) or pallet substructure is arranged substantially below a tread element and in the case of a step also behind a setting element.
- the step substructure or pallet substructure comprises a front cross member and a rear cross member or a rear cross member, which together define or define a plane for receiving a tread element.
- the tread element serves as a step or Trittpalette for passengers or passengers, which are transported with the driving device.
- a central longitudinal strut (center support or center strut or tension strut), which is substantially parallel to the step cheeks or pallet cheeks and perpendicular to the two cross members.
- the longitudinal strut connects the two cross members.
- the cross members are made of deep-drawn sheet metal and welded to the supporting cheeks or pallet cheeks to a supporting frame or connected or riveted or screwed or verclincht or glued.
- the height of the cross member at the ends is smaller than the height of the cross member in the middle, so that the cross member have a bulbous shape.
- the height of the cross member in the middle is at least 1.5 times and at most twice as large as the height of the cross member at the ends, so that results in the cross members under load a uniform voltage curve.
- the mechanical stability is highest in the middle, where it is needed the most, and at the edge, where less mechanical stability is needed, the lower height saves weight.
- a stability can be achieved even with relatively thin deep-drawn sheet, which comes close to the stability of the known thick and heavy sheet metal angle, although the weight is much lower.
- driving device 1 is an escalator, which connects a lower level E1 with an upper level E2.
- the driving device 1 has lateral balustrades 4 and base plates 3 and an endless conveyor with drive trains.

- the front cross member 24 is dimensioned less large than the rear cross member 22, since the rear cross member 22 in the step edge (edge between tread element 9 and setting element 14) is arranged and there heavy loads, ie higher loads than the front cross member 24 exposed becomes.
- the length L1 is smaller than the length L2 (see Fig. 4B ), the length being measured in the direction of travel.
- the front cross member 24 is made For reasons of weight optimization or material efficiency smaller dimensioned or designed smaller than the rear cross member 22.

- a H380 or H400 thermoforming sheet is used for parts of the step substructure 17, wherein the numbers 380 and 400 indicate the yield strength in N / mm 2 .
- These sheets are particularly suitable because a tensile breaking strength of at least 900 N / mm 2 given is. Moreover, it is particularly advantageous if the sheets have a tensile breaking strength of at least 1100 N / mm 2 .
- the deep drawing sheet used preferably has a thickness between 0.75 mm and 1.9 mm. Particularly preferred is a thickness of 1.1 to 1.6 mm.
- thermoforming sheet is chosen according to the above specifications, then the step cheeks, respectively the step (s), will comply with all EN 115: Safety rules for the construction and installation of escalators and moving walkways, as well as the AN - American National Standard - ASME A17 .1-2004: Safety code for elevators and escalators.

- the invention can be applied not only on escalators, but also on moving walks. This will now be based on the 10 to 18 explained. Many parts of the pallet for the moving walk have their equivalent at the step for the escalator; these parts bear the same reference number, but with an apostrophe provided; so does the tread element the pallet the reference numeral 9 ', because the tread element of the stage is denoted by 9. If there is agreement with the level, the parts will not be explained again.

- a strike plate 27' for stiffening the Schlepprollenauges 30 'is a strike plate 27' (see Fig. 16 ), which has an opening 27 '', which serves to receive the tow roller axle. It is so mounted on the pallet cheek 20.2 '(eg, welded) that the opening 27''and the Schlepproollenauge 32' are coaxial (see Fig. 11 ).
- the tow roller axle is supported at two axially spaced points. Since the two chain pin axles 21.1 'and 21.2' are connected to one another via the pallet axis 21.3 ', no torsional forces act on the pallet eyes 32', so that no striking plate is necessary.

Description
Die Erfindung betrifft einen Stufenunterbau bzw. Palettenunterbau für Fahreinrichtungen nach dem Oberbegriff des Anspruchs 1, Tritteinheiten, also Stufen bzw. Paletten mit solch einem Stufenunterbau bzw. Palettenunterbau und Fahreinrichtungen mit solchen Tritteinheiten.The invention relates to a step substructure or pallet substructure for vehicles according to the preamble of
Fahreinrichtungen im Sinne der Erfindung, die auch als Fördereinrichtungen bezeichnet werden können, sind Fahrtreppen und Fahrsteige mit einer Vielzahl von Tritteinheiten, d.h. Stufen oder Fahrsteigpaletten, die zu einem Endlosförderer verbunden sind. Benutzer der Fahreinrichtungen stehen auf Trittflächen der Tritteinheiten oder sie gehen auf den Tritteinheiten in gleicher Bewegungsrichtung, wie die Fähreinrichtungen fahren bzw. sich fortbewegen.Driving devices according to the invention, which may also be referred to as conveyors, are escalators and moving walks with a plurality of treading units, i. Steps or pavement pallets connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they walk on the kiting units in the same direction of movement as the ferry devices drive or move.
Bei Fahrtreppen bilden die Tritteinheiten Fahrtreppenstufen, im Weiteren als Stufen bezeichnet, und bei Fahrsteigen bilden die Tritteinheiten Fahrsteigpaletten, im Weiteren als Paletten bezeichnet. Fahrtreppen überwinden mit relativ grossem Neigungswinkel grössere Höhenunterschiede wie ganze Stockwerke. Fahrsteige hingegen verlaufen horizontal oder leicht schräg, aber im Allgemeinen mit geringeren Neigungswinkeln als Fahrtreppen.For escalators, the tread units form escalator steps, hereafter referred to as steps, and for ride surfaces, the tread units form pavement pallets, hereafter referred to as pallets. Escalators overcome with relatively large inclination greater differences in height as entire floors. Moving walkways, on the other hand, run horizontally or slightly at an angle, but generally with lower angles of inclination than escalators.
Typischerweise umfassen solche Fahreinrichtungen Antriebsstränge, die als Stufen- oder Palettenketten ausgebildet sind. Im Folgenden ist der Einfachheit halber lediglich von Antriebssträngen die Rede. Diese Antriebsstränge werden angetrieben, um die Stufen oder Paletten in Förderrichtung zu bewegen, und sie sind gemäss dem Stand der Technik in gleichmässigen Abständen mit so genannten Stufenrollen bzw.Typically, such driving devices include drive trains, which are designed as stepped or pallet chains. In the following, for the sake of simplicity, only drive trains are mentioned. These drive trains are driven to move the steps or pallets in the conveying direction, and they are according to the prior art at regular intervals with so-called step rollers or
Palettenrollen (Laufrollen, Kettenrollen) versehen. Diese Laufrollen fahren bzw. rollen entlang von dedizierten bzw. vorgesehenen Laufschienen. Im Bereich der Enden der Fahreinrichtungen laufen die Antriebsstränge mit den Laufrollen um Umlenkräder (z.B. Kettenräder) herum und vollziehen so einen Richtungswechsel. Anstatt der Schlepprollen können auch Gleitelemente eingesetzt werden. Die Gleitelemente oder die Rollelemente (Laufrollen) sind unmittelbar an einer Stufen- oder Palettenkette befestigt, die als Antriebsstrang dient, wie weiter oben beschrieben.Pallet rollers (rollers, chain rollers) provided. These casters move or roll along dedicated rails. In the area of the ends of the driving devices, the drive trains run around the rollers around deflection wheels (for example sprockets) and thus make a change of direction. Instead of the tow rollers and sliding elements can be used. The sliding elements or rollers (rollers) are directly attached to a step or pallet chain, which serves as a drive train, as described above.
Zusätzlich zu den Stufen- oder Palettenketten samt der daran befestigten Gleit- oder Rollelemente sind pro Stufe bzw. Palette zwei weitere Rollen erforderlich, die als Schlepprollen bezeichnet werden und entlang separater Führungsschienen rollen.In addition to the step or pallet chains, including the sliding or rolling elements attached thereto, two further rollers are required per step or pallet, which are referred to as drag rollers and roll along separate guide rails.
Die Stufen bzw. Paletten sind bisher relativ aufwendig zu fertigen bzw. zu giessen und auch teuer, da sie in sich sehr stabil und verwindungssteif sein müssen. Ausserdem müssen die Stufen bzw. Paletten sehr genau gefertigt sein, um einen sicheren, ruhigen, ruckfreien Lauf zu garantieren. Ein wesentliches Element jeder Stufe bzw. jeder Palette ist der Stufenunterbau bzw. der Palettenunterbau, der eine solide, wesentliche Tragfunktion hat. Der Unterbau muss sehr stabil, standfest, verwindungssteif und leicht sein, was zu hohem Materialaufwand bzw. Materialeinsatz und Bearbeitungskosten sowie Druckgussfertigungskosten führt.The stages or pallets have been relatively expensive to manufacture or pour and also expensive, since they must be very stable and torsionally rigid. In addition, the steps or pallets must be made very accurately in order to guarantee a safe, quiet, jerk-free run. An essential element of each step or pallet is the stepped substructure or pallet substructure, which has a solid, essential supporting function. The substructure must be very stable, stable, torsionally stiff and lightweight, which leads to high material costs and material use and processing costs and die-casting production costs.
Es sind schon verschiedene Vorschläge gemacht worden, wie das Gewicht des Stufenunterbaus bzw. des Palettenunterbaus verringert werden kann.Various proposals have already been made as to how the weight of the stepped substructure or of the pallet substructure can be reduced.

Schließlich ist auch in der
Besonders für eine kostengünstigere Erstausrüstung von Fahreinrichtungen besteht der Wunsch, die Stufen und Paletten durch günstigere Teile zu ersetzen, ohne dabei jedoch die Laufruhe, die Fahreigenschaften, die Stabilität, die Robustheit und die Zuverlässigkeit sowie die Standfestigkeit zu beeinträchtigen. Ausserdem soll der Herstellungsprozess vereinfacht und beschleunigt werden. Darüber hinaus soll das Gewicht nicht erhöht werden, um dadurch die Laufeigenschaften nicht zu beeinträchtigen.Especially for a more cost-effective original equipment of driving equipment is the desire to replace the steps and pallets with cheaper parts, but without compromising smoothness, ride quality, stability, robustness and reliability and stability. In addition, the manufacturing process should be simplified and accelerated. In addition, the weight should not be increased so as not to affect the running properties.
Aufgabe der Erfindung ist es daher,
- einen kostengünstigeren Stufenunterbau bzw. Palettenunterbau für eine Fahreinrichtung der eingangs genannten Art zu schaffen, der aber trotzdem sämtlichen Anforderungen bzw. Anforderungsprofilen genügt und einen sicheren, ruhigen, ruckfreien Lauf ermöglicht, nicht störungsanfällig ist und eine lange Laufzeit bzw. hohe Lebensdauer garantiert.
- To create a more cost-effective step substructure or pallet base for a driving device of the type mentioned, but still satisfies all requirements or requirements profiles and allows safe, quiet, smooth running, is not prone to failure and a long life or long service life guaranteed.
Ausserdem soll der Materialeinsatz bzw. Materialaufwand möglichst gering sein;
- eine kostengünstigere Fahreinrichtung der eingangs genannten Art zu schaffen, die einen sicheren, ruhigen, ruckfreien Lauf ermöglicht, nicht störungsanfällig ist und eine hohe Lebensdauer bzw. lange Laufzeit garantiert.
- to provide a cheaper driving device of the type mentioned above, which allows a safe, quiet, smooth running, is not prone to failure and a long life or long term guaranteed.
Diese Aufgabe wird erfindungsgemäss gelöst durch die Merkmale des Anspruchs 1 und die Merkmale des Anspruchs 7.This object is achieved according to the invention by the features of
Ein erfindungsgemässer Stufenunterbau (Stufentraggestell, Stufentragrahmen) bzw. Palettenunterbau ist im Wesentlichen unterhalb eines Trittelementes und im Falle einer Stufe auch hinter einem Setzelement angeordnet. Der Stufenunterbau bzw. Palettenunterbau umfasst einen vorderen Querträger und einen hinteren Querträger bzw. eine hintere Querbrücke, die zusammen eine Ebene zur Aufnahme eines Trittelementes definieren bzw. festlegen. Das Trittelement dient als Trittstufe bzw.
Trittpalette für Passagiere bzw. Fahrgäste, die mit der Fahreinrichtung befördert werden. Es sind an dem Stufenunterbau bzw. Palettenunterbau zwei äussere Stufenwangen bzw.
Palettenwangen vorgesehen, wobei eine der Stufenwangen bzw. Palettenwangen rechts und eine der Stufenwangen bzw.
Palettenwangen links im Wesentlichen senkrecht zu den Querträgern angeordnet ist. Es kann eine mittlere Längsstrebe (Mittenträger bzw. Mittenstrebe bzw. Zugstrebe) vorgesehen werden, die im Wesentlichen parallel zu den Stufenwangen bzw. Palettenwangen und senkrecht zu den beiden Querträgern verläuft. Die Längsstrebe verbindet die beiden Querträger. Die Querträger sind aus Tiefziehblech gefertigt und mit den Stufenwangen bzw. Palettenwangen zu einem tragenden Rahmen verschweisst oder verbunden oder vernietet oder verschraubt oder verclincht oder verklebt. Erfindungsgemäß ist die Höhe der Querträger an deren Enden kleiner als die Höhe der Querträger in der Mitte, sodass die Querträger eine bauchige Form aufweisen. Erfindungsgemäß ist die Höbe der Querträger in der Mitte mindestens 1,5-mal so groß und höchstens doppelt so groß wie die Höbe der Querträger an deren Enden, so dass sich in den Querträgern unter Belastung ein gleichnäßiger Spannungsverlauf ergibt.An inventive step substructure (step support frame, step support frame) or pallet substructure is arranged substantially below a tread element and in the case of a step also behind a setting element. The step substructure or pallet substructure comprises a front cross member and a rear cross member or a rear cross member, which together define or define a plane for receiving a tread element. The tread element serves as a step or
Trittpalette for passengers or passengers, which are transported with the driving device. There are at the step base or pallet base two outer step cheeks or
Provided pallet cheeks, wherein one of the step cheeks or pallet cheeks right and one of the step cheeks or
Pallet cheeks left is arranged substantially perpendicular to the cross beams. It can be provided a central longitudinal strut (center support or center strut or tension strut), which is substantially parallel to the step cheeks or pallet cheeks and perpendicular to the two cross members. The longitudinal strut connects the two cross members. The cross members are made of deep-drawn sheet metal and welded to the supporting cheeks or pallet cheeks to a supporting frame or connected or riveted or screwed or verclincht or glued. According to the invention the height of the cross member at the ends is smaller than the height of the cross member in the middle, so that the cross member have a bulbous shape. According to the invention the height of the cross member in the middle is at least 1.5 times and at most twice as large as the height of the cross member at the ends, so that results in the cross members under load a uniform voltage curve.
Auf diese Weise ist die mechanische Stabilität in der Mitte, wo sie am meisten gebraucht wird, am höchsten, und am Rand, wo weniger mechanische Stabilität gebraucht wird, wird durch die geringere Höhe Gewicht gespart. Auf diese Weise kann auch mit relativ dünnem Tiefziehblech eine Stabilität erreicht werden, die der Stabilität der bekannten dicken und schweren Blechwinkel nahe kommt, obwohl das Gewicht wesentlich geringer ist.In this way, the mechanical stability is highest in the middle, where it is needed the most, and at the edge, where less mechanical stability is needed, the lower height saves weight. In this way, a stability can be achieved even with relatively thin deep-drawn sheet, which comes close to the stability of the known thick and heavy sheet metal angle, although the weight is much lower.
Bevorzugte Weiterbildungen des erfindungsgemässen Unterbaus und der Fahreinrichtung sind durch die abhängigen Ansprüche definiert.Preferred developments of the inventive substructure and the driving device are defined by the dependent claims.

Die Träger 22, 23, 24 und die Stufenwangen 20.1, 20.2 sind miteinander verschweisst oder vernietet oder verbunden oder verschraubt oder verklebt oder verclincht. Vorzugsweise werden Punktschweissungen bzw. Buckelschweissungen vorgenommen, um diese Elemente mit einander zu verbinden. Hier zeigt sich ein anderer Vorteil der Erfindung: Da die Stufenwangen 20.1, 20.2 aus Blech bzw. Stahlblech bzw. NIROSTA-Blech bzw. Zinkblech bzw. Kupferblech gefertigt sind, können sie problemlos mit anderen Blechelementen (z.B. den Trägern 22, 23, 24) verschweisst oder vernietet oder verbunden oder verschraubt oder verklebt oder verclincht werden. Auch die Anwendung von feuerverzinkten bzw. elektrolytisch verzinkten Blechen ist bei Punktschweissungen bzw. Bückelschweissungen möglich, da der Oberflächenschutz gegenüber Korrosion beim Schweißen nicht beschädigt wird. Das Schweissen bzw. das Giessen bzw. das Druckgiessen von Aluminiumelementen hingegen ist teuer und aufwendig sowie zeitintensiv. Das Zusammenfügen der Elemente eines Stufenunterbaus mittels Schrauben, wie es teilweise gemacht wird, ist sehr aufwendig und bietet nicht die gewünschte Dauerstabilität bzw. Standfestigkeit bzw.

Weiterhin sind so genannte Befestigungsbereiche 19 vorgesehen. In den Befestigungsbereichen 19 sind im Blech bzw. Stahlblech bzw. NIROSTA-Blech bzw. Zinkblech bzw.

Anders als bei bisherigen Stufenunterbauten kommen gemäss der Erfindung Elemente (z.B. die Träger 22, 23, 24 und die Stufenwangen 20.1, 20.2) zum Einsatz, deren Form und Dicke den jeweiligen mechanischen Belastungen angepasst sind. Bisher hatten z.B. die Querträger 22, 24 des Stufenunterbaus, die zum Teil auch als Querbrücken bezeichnet werden, ein einfaches Querschnittprofil mit gleichbleibendem Querschnitt über die gesamte.

Durch das Tiefziehen können problemlos sowohl L- als auch U-förmige Profile erzeugt werden. Beim Tiefziehen wird aus dem flachen Blechquerschnitt (z.B. Blech von einem Stahlcoil) ein Hohlkörper bzw. Körper bzw. Träger bzw. Hohlträger bzw. eine Brücke mit möglichst gleicher Blechdicke erzeugt.Deep-drawing makes it easy to create both L- and U-shaped profiles. In deep-drawing, a hollow body or body or carrier or hollow carrier or a bridge with the same sheet metal thickness as possible is produced from the flat sheet metal cross section (for example sheet metal from a steel coil).
Vorzugsweise ist der vorderer Querträger 24 weniger gross dimensioniert als der hintere Querträger 22, da der hintere Querträger 22 im Bereich der Stufenkante (Kante zwischen Trittelement 9 und Setzelement 14) angeordnet ist und dort starken Belastungen, d.h. stärkeren Belastungen als der vordere Querträger 24, ausgesetzt wird.

Vorzugsweise wird ein H380 oder H400 Tiefziehblech für Teile des Stufenunterbaues 17 verwendet, wobei die Zahlen 380 bzw. 400 die Streckgrenze in N/mm2 angeben. Besonders geeignet sind diese Bleche, weil eine Zug-Bruchgrenze von mindestens 900 N/mm2 gegeben ist. Darüber hinaus ist besonders vorteilhaft, wenn die Bleche eine Zug-Bruchgrenze von mindestens 1100 N/mm2 aufweisen.Preferably, a H380 or H400 thermoforming sheet is used for parts of the
Das verwendete Tiefziehblech hat vorzugsweise eine Dicke zwischen 0,75 mm und 1,9 mm. Besonders bevorzugt ist eine Dicke von 1,1 bis 1,6 mm.The deep drawing sheet used preferably has a thickness between 0.75 mm and 1.9 mm. Particularly preferred is a thickness of 1.1 to 1.6 mm.
Falls das Tiefziehblech entsprechend der obigen Angaben gewählt wird, dann erfüllen die Stufenwangen, respektive die Stufe(n) alle Belastungstests der Norm EN 115: Sicherheitsregeln für die Konstruktion und den Einbau von Fahrtreppen und Fahrsteigen, sowie der AN - American National Standard - ASME A17.1-2004: Safety code for elevators and escalators.If the thermoforming sheet is chosen according to the above specifications, then the step cheeks, respectively the step (s), will comply with all EN 115: Safety rules for the construction and installation of escalators and moving walkways, as well as the AN - American National Standard - ASME A17 .1-2004: Safety code for elevators and escalators.
Vorzugsweise weist das Tiefziehblech eine Oberflächenbeschichtung auf. Besonders bevorzugt sind Oberflächenbeschichtungen, die durch Tauchlackieren erzeugt werden.Preferably, the deep-drawn sheet has a surface coating. Particularly preferred are surface coatings which are produced by dip coating.
Besonders geeignet ist das kathodische Tauchlackieren (KTL).Particularly suitable is the cathodic dip coating (KTL).
Das Ergebnis des KTL ist eine sehr gleichmäßige Beschichtung des Tiefziehblechs mit gleichmäßigen Schichtdicken und guten Oberflächenqualitäten. Nach der KTL-Behandlung weist das Tiefziehblech eine gleichmässige, durchgehende Lackschicht auf. Besonders gute Ergebnisse werden erzielt, wenn die KTL-Behandlung nach dem Tiefziehen des Blechs angewendet wird.The result of the KTL is a very uniform coating of the deep-drawn sheet with uniform layer thicknesses and good surface qualities. After the KTL treatment, the deep-drawn sheet has a uniform, continuous lacquer layer. Particularly good results are achieved when the KTL treatment is applied after deep drawing of the sheet.
Es ist auch eine Anwendung der KTL-Behandlung vor dem Tiefziehen denkbar.
