Abstract
Description
Die vorliegende Erfindung betrifft eine Einrichtung zur Verminderung von Luftströmungsgeräuschen an schnellfahrenden Aufzugkabinen, die, in Form einer aerodynamisch günstig geformten Haube, entweder auf dem Kabinendach oder unter dem Kabinenboden oder an beiden Positionen zugleich angebracht ist. Eine Aufzugkabine ist Teil einer Aufzuganlage, die im wesentlichen aus folgenden Komponenten besteht: Einem Liftschacht mit Führungsschienen, der erwähnten Aufzugkabine mit ihrem Kabinenrahmen, einem Gegengewicht, den Tragseilen für Kabine und Gegengewicht, sowie einer Antriebseinheit mit Treibscheibe, welche diese Tragseile antreibt. Schnellfahrende Kabinen sind auch an ihrer Unterseite durch über eine Rolle im Schachtgrund laufende Unterseile mit dem Gegengewicht verbunden. Die Aufzugkabine ist elastisch in einem Kabinenrahmen gelagert, der an den Tragseilen hängt, über Führungselemente von den Führungsschienen in Hubrichtung geführt wird, und der den im Betrieb und bei Pannen auftretenden Belastungen entsprechend stabil gebaut ist.The present invention relates to a device for reduction of air flow noises in fast-moving elevator cars, the, in the form of an aerodynamically shaped Hood, either on the cabin roof or under the cabin floor or is attached at both positions at the same time. An elevator car is part of an elevator system, which is essentially consists of the following components: a lift shaft with Guide rails, the elevator car mentioned with its car frame, a counterweight, the cables for the cabin and Counterweight, as well as a drive unit with traction sheave, which drives these suspension cables. Fast-moving cabins are also on its underside through a roller in the shaft bottom running lower ropes connected to the counterweight. The elevator car is elastically supported in a car frame, that hangs on the suspension cables, via guide elements from the Guide rails is guided in the stroke direction, and the in Operation and corresponding loads in the event of breakdowns is built stable.
Kabinen von Aufzuganlagen sind üblicherweise als strömungstechnisch ungünstige, quaderförmige Körper mit scharfen Kanten ausgeführt, die sich in meist engen Aufzugschächten bewegen. Bei Fahrgeschwindigkeiten über etwa 4 m/s verursachen die auftretenden Luftwirbel und Strömungsablösungen unangenehme bis stark störende Geräusche. Zur Reduktion dieser Geräusche werden an schnellfahrenden Aufzugkabinen in einer oder beiden Fahrrichtungen haubenartige Aufbauten mit strömungstechnisch günstiger Form angebracht, mit dem Ziel, die verdrängte Luftmenge möglichst wirbel- und ablösungsfrei um den Kabinenkörper herumzuleiten. Cabins of elevator systems are usually considered to be fluidic unfavorable, cuboid body with sharp edges executed, which move in mostly narrow elevator shafts. At speeds above about 4 m / s they cause occurring air vortices and flow separation uncomfortable up strong disturbing noises. To reduce this noise on fast-moving elevator cars in one or both directions hood-like structures with more favorable flow technology Form attached, with the aim of displacing the amount of air as free of eddies and detachments as possible around the cabin body.
US 5,220,979 offenbart mehrere Lösungen für strömungsverbessernde Anbauten an Aufzugkabinen. Alle dort beschriebenen Lösungen beinhalten die Merkmale, dass die Anbauten auf der Seite des Kabineneingangs ebene Flächen in der Fortsetzung der Kabinenfrontwand nach unten bzw. nach unten und oben aufweisen, und dass deren Wände als stabile Platten oder Formteile ausgeführt sind.US 5,220,979 discloses several solutions for flow improving Attachments to elevator cars. All described there Solutions include the features that the extensions on the Side of the cabin entrance flat surfaces in the continuation of the Have the cabin front wall facing downwards or downwards and upwards, and that their walls are designed as stable plates or molded parts are.
GB 2 280 662 beschreibt ebenfalls strömungsverbessernde Einrichtungen
zu Aufzugkabinen, wobei die Passagierkabine schwingungsisoliert
in ein geschlossenes, strömungstechnisch günstig
ausgebildetes Gehäuse eingebaut ist. Wie bei US 5,220,979
enthalten auch die in GB 2 280 662 gezeigten strömungsgünstigen
Gehäuse auf der Seite des Kabineneingangs ebene Flächen als
Fortsetzung der Kabinenfrontwand nach oben bzw. nach unten, und
die Wände dieser Gehäuse bestehen aus stabilen Formteilen.
Beide oben erwähnten Lösungen haben die Nachteile, dass die offenbarten strömungsgünstigen Anbauten und Gehäuse schwere und sperrige Komponenten sind, die voluminöse Verpackungen erfordern und schwierig zu transportieren und zu montieren sind und das von der Aufzuganlage zu bewegende Kabinengewicht massiv erhöhen. Ausserdem ist die Herstellung von Hauben mit mehrachsig gekrümmten Flächen, wie sie in beiden Schriften dargestellt sind, sehr aufwendig, insbesondere da diese Hauben auf eine Vielzahl von unterschiedlichen Kabinenabmessungen angepasst werden müssen.Both of the solutions mentioned above have the disadvantages that the disclosed aerodynamic attachments and housing heavy and are bulky components that require bulky packaging and are difficult to transport and assemble and the car weight to be moved by the elevator system is massive increase. In addition, the production of hoods is multi-axis curved surfaces, as shown in both writings are very expensive, especially since these hoods on one Variety of different cabin dimensions adapted Need to become.
Gegenstand der vorliegenden Erfindung sind strömungsgünstige Aufzugkabinenhauben, die preisgünstig und flexibel herstellbar, volumenarm zu verpacken sowie leicht zu transportieren und zu montieren sind und eine geringe Masse aufweisen.The present invention relates to aerodynamic flow Elevator canopies that can be manufactured inexpensively and flexibly, low volume packaging and easy to transport and close are assembled and have a low mass.
Erfindungsgemäss wird dies dadurch erreicht, dass solche strömungsgünstigen Kabinenhauben nicht aus stabilen Formteilen, sondern aus einer membranartigen, flexiblen und faltbaren Folie hergestellt werden. Kabinenhauben dieser Ausführungsart weisen im Vergleich mit bekannten strömungsverbessernden Kabinenaufbauten folgende wesentliche Vorteile auf:
- Für ihre Herstellung sind keine Spezialmaschinen, Pressformen oder Modelle erforderlich, wie dies bei stabilen Formteilen der Fall ist. In Anbetracht der zahlreichen Varianten von Kabinenabmessungen werden dadurch entscheidende Kosteneinsparungen erreicht.
- Die zusammengefaltete flexible Haube ist volumenarm und kostengünstig zu transportieren und leicht zu montieren.
- Dank der dünnen, meabranartigen Haubenwand, bleibt die von der Aufzugsanlage zusätzlich zur Kabine zu bewegende Haubenmasse minimal.
- No special machines, molds or models are required to manufacture them, as is the case with stable molded parts. In view of the numerous variants of cabin dimensions, decisive cost savings are achieved.
- The folded flexible hood is low-volume and inexpensive to transport and easy to assemble.
- Thanks to the thin, membrane-like hood wall, the hood mass to be moved by the elevator system in addition to the car remains minimal.

Fig. 1 zeigt zwei erfindungsgemässe Aufzugkabinenhauben (1) aus membranartiger, flexibler Folie, die an einer Aufzugkabine (2) über dem Kabinendach (3) wie auch unter dem Kabinenboden (4) angebracht sind. Die Folie ist reissfest und besteht vorzugsweise aus Kunststoff, z. B. PVC, aus Zeltstoff, Gummi oder dergleichen. Die Aufzugkabine ist an Führungsschienen (5) mittels Führungsrollen (6) geführt und zwischen Tragseilen (7) und sogenannten Unterseilen (8) aufgehängt. Dargestellt ist eine bevorzugte Ausführungsform der strömungsgünstigen Haube, die einer leicht abgestumpften Pyramide gleicht, deren Grundfläche dem Kabinengrundriss entspricht, und bei der die Seitenflächen so stark gewölbt sind, dass vertikale Querschnitte durch ihr Zentrum annähernd eine halbe Ellipse bilden. Die Kuppe der Haube liegt über oder unter dem Zentrum der Kabine. Die Kabinenhaube ist üblicherweise aus mehreren geeignet zugeschnittenen Teilflächen zusammengeschweisst. Selbstverständlich sind auch anders geformte strömungsgünstige Hauben mit der erfindungsgemässen Technik realisierbar.1 shows two elevator car hoods (1) according to the invention membrane-like, flexible film attached to an elevator car (2) above the cabin roof (3) as well as under the cabin floor (4) are attached. The film is tear-resistant and is preferably made made of plastic, e.g. B. PVC, tent fabric, rubber or the like. The elevator car is on guide rails (5) guided by means of guide rollers (6) and between support cables (7) and so-called lower ropes (8) suspended. Is shown a preferred embodiment of the aerodynamic hood, that resembles a slightly truncated pyramid, the base of which corresponds to the cabin floor plan, and in which the side surfaces are so strongly curved that vertical cross sections form approximately half an ellipse through its center. The The top of the hood lies above or below the center of the cabin. The canopy is usually suitable from several cut sections welded together. Of course are also differently shaped aerodynamic hoods realizable with the inventive technology.
In den Seitenwänden der Aufzugkabinenhauben (1) erkennbar sind verschliessbare Öffnungen (9), die an geeigneten Stellen in die membranartige Haubenwand eingearbeitet sind und den Durchtritt für zu evakuierende Passagiere ermöglichen, sowie die Räume über dem Kabinendach und unter dem Kabinenboden für Servicearbeiten zugänglich machen. Als Verschliessmittel dienen vorzugsweise Reissverschlüsse; es sind aber auch andere Verschliessarten, wie Klettverschlüsse, Seil/Ösen-Verschlüsse, etc. anwendbar. Ebenfalls in Fig. 1 sichtbar sind beidseitig an den Aufzugkabinenhauben (1) vorhandene Einbuchtungen (10), die den Einbauraum für die Führungsrollen (6) und die in diesem Bereich integrierten Sicherheitsvorrichtungen freigeben. Can be seen in the side walls of the elevator car hoods (1) closable openings (9) in the appropriate places in the membrane-like hood wall are incorporated and the passage for passengers to be evacuated, as well as the rooms above the cabin roof and under the cabin floor for service work make available. Preferably serve as a closing agent Zippers; but there are also other types of closures, such as Velcro closures, rope / eyelet closures, etc. applicable. Also visible in Fig. 1 are on both sides of the elevator car hoods (1) existing indentations (10) that the Installation space for the guide rollers (6) and those in this area release integrated safety devices.
Fig. 2 zeigt eine auf dem oberen Querjoch (11) des Kabinenrahmens (12) befestigte Stützkonstruktion (13), die der Kabinenhaube aus flexibler Folie die erforderliche Stabilität verleiht. Erkennbar sind der Grundrahmen (14) der Stützkonstruktion mit den Befestigungslementen (15) für seine Fixierung am Kabinenrahmen, der kleine obere Rechteckrahmen (16) für den Durchtritt der Tragseile, sowie eine Anzahl der Haubenform entsprechend angeordneten und ellipsenförmig gebogenen, vertikal orientierten Stützstäbe (17). Deren Lage wird teilweise durch die, im vorhergehenden den Abschnitte beschriebenen, seitlichen Einbuchtungen (10) in der Kabinenhaube bestimmt.Fig. 2 shows one on the upper transverse yoke (11) of the cabin frame (12) attached support structure (13) that of the canopy from flexible film gives the necessary stability. The base frame (14) of the support structure can be seen with the fastening elements (15) for its fixation on Cabin frame, the small upper rectangular frame (16) for the Passage of the suspension cables, as well as a number of the hood shape accordingly arranged and bent elliptically, vertically oriented support rods (17). Their location becomes partial by the ones described in the previous sections lateral indentations (10) determined in the canopy.
Der Grundrahmen (14) wird bei Montage mit dem oberen Querjoch
(11) des oben erwähnten Kabinenrahmens (12) fest verschraubt.
Da die Aufzugkabine (2) über Schwingungsisolationselemente (18)
in diesem Rahmen gelagert ist, wird mit dieser Art der Haubenbefestigung
die Körperschallübertragung zwischen Haube und
Kabine weitgehend vermieden.
Durch Anwendung von Schraubverbindungen an geeigneten Stellen
ist die beschriebene Stützkonstruktion (13) für den Transport
in Teile von geeigneter Grösse zerlegbar.
Wird bei Anlagen mit hoher Maximalgeschwindigkeit und mit
erhöhten Ansprüchen betreffend Geräuschreduzierung zusätzlich
eine gleiche Haube in umgekehrter Einbaulage unter dem Kabinenboden
angebracht, so wird der Grundrahmen dieser zweiten Haube
am unteren Querjoch des Kabinenrahmens befestigt. Die Durchtrittsöffnung
im kleinen Rechteckrahmens ist hier für die
vorgängig erwähnten 
By using screw connections at suitable points, the described support structure (13) can be dismantled into parts of a suitable size for transport.
If, in the case of systems with high maximum speed and with increased demands regarding noise reduction, the same hood is additionally installed in the reverse installation position under the cabin floor, the base frame of this second hood is fastened to the lower transverse yoke of the cabin frame. The passage opening in the small rectangular frame is here for the previously mentioned
Fig. 3 zeigt anhand eines Horizontalschnitts durch eine flexible Aufzugkabinenhaube (1) die Anordnung und Befestigung der durch Verschweissen formgeschnittener Folienkomponenten vorkonfektionierten Haubenwandteile. Im Normalfall besteht die Haubenwand aus einer vorderen Hälfte (1.1), einer hinteren Hälfte (1.2), sowie aus zwei Folien (1.3) für den Abschluss der seitlichen Einbuchtungen. Zu erkennen ist in Fig. 3 auch, wie die erwähnten Haubenwandteile mit Hilfe von an deren Rändern angebrachten Ösen sowie von Schnüren (19) an den vertikal orientierten Stützstäben (17) der Stützkonstruktion befestigt und gespannt werden.Fig. 3 shows a horizontal section through a flexible Elevator canopy (1) the arrangement and attachment of the pre-assembled by welding molded film components Hood wall parts. The hood wall normally exists from a front half (1.1), a rear half (1.2), as well as two foils (1.3) for the end of the side Indentations. It can also be seen in FIG. 3 how the mentioned hood wall parts with the help of attached to their edges Eyelets and cords (19) on the vertically oriented Support rods (17) attached to the support structure and be excited.
Fig. 4 zeigt diese Fixierung der Haubenwand an den Stäben mittels Ösen (20) und Schnüren (19) etwas detaillierter. Die dargestellten Befestigungsstreifen (21) werden bei der Konfektionierung der Haubenteile an richtiger Position eingeschweisst und enthalten die erforderliche Anzahl Ösen.Fig. 4 shows this fixation of the hood wall on the rods somewhat more detailed using eyelets (20) and cords (19). The shown fastening strips (21) are used in the assembly of the hood parts welded in the correct position and contain the required number of eyelets.
Aus Fig. 5 erkennt man, wie die flexiblen Haubenwandteile (1.1, 1.2) mit gleicher Ösen/Schnur-Technik am Grundrahmen der Stützkonstruktion sowie mit Schrauben (22) und Leiste (23) am Kabinendach (3) fixiert sind.5 shows how the flexible hood wall parts (1.1, 1.2) with the same eyelet / cord technology on the base frame of the support structure and with screws (22) and ledge (23) on the cabin roof (3) are fixed.
Fig. 6 zeigt schematisch eine weitere mögliche Ausführungsform
der flexiblen Kabinenhaube. Bei dieser wird die erforderliche
Stabilität nicht mittels Stützkonstruktion aus gebogenen Stäben,
sondern durch an der Innenseite der vorkonfektionierten
Haube fixierte, aufblasbare schlauchförmige Luftkammern (24)
erreicht. Die Fixierung erfolgt mittels an der Haubeninnenwand
angeschweissten Befestigungslaschen (25), wie dies in Fig. 6 ,
Schnitt VI-VI erkennbar ist. Die räumliche Anordnung dieser
Luftkammern entspricht in etwa derjenigen der Stützstäbe (17)
der Stützkonstruktion (13) in Fig. 2. Die Form der durch Luftdruck
in den Kammern aufgerichteten Haube ergibt sich aus der
Form der zugeschnittenen und miteinander verschweissten Haubenteile.
Die Luftkammern bestehen vorzugsweise aus gewebeverstärkten,
flexiblen und luftdichten Schläuchen, die auf beiden
Seiten mit Stopfen (26) verschlossen sind und ein Aufblasventil
(27) enthalten. Am Grundrahmen (14) und am oberen Rechteckrahmen
(16) sind Rohrstücke (28) angebracht, die die Enden der
schlauchförmigen Luftkammern aufnehmen und ihnen die gewünschte
Anfangsrichtung aufzwingen.
Der Vorteil dieser Lösung gegenüber der Stützkonstruktion mit
starren Stäben liegt darin, dass die Luftkammern bereits richtig
positioniert in die vorkonfektionierte flexible Haubenwand
eingearbeitet werden können. Dadurch kann bei Montage das
Befestigen der Haubenwand an den Stützstäben eingespart werden.
Ausserdem kann mit dieser Technik die Haubenwand einstückig
ausgeführt werden.Fig. 6 shows schematically another possible embodiment of the flexible canopy. In this case, the required stability is not achieved by means of a support structure made of bent rods, but by means of inflatable tubular air chambers (24) fixed to the inside of the prefabricated hood. The fixing is carried out by means of fastening tabs (25) welded to the inner wall of the hood, as can be seen in FIG. 6, section VI-VI. The spatial arrangement of these air chambers corresponds approximately to that of the support rods (17) of the support structure (13) in Fig. 2. The shape of the hood erected by air pressure in the chambers results from the shape of the cut and welded hood parts. The air chambers preferably consist of fabric-reinforced, flexible and airtight hoses which are closed on both sides with plugs (26) and contain an inflation valve (27). Tubes (28) are attached to the base frame (14) and to the upper rectangular frame (16), which take up the ends of the tubular air chambers and force them into the desired starting direction.
The advantage of this solution compared to the support structure with rigid rods is that the air chambers can already be positioned correctly in the pre-assembled flexible hood wall. As a result, the fastening of the hood wall to the support rods can be saved during assembly. In addition, the hood wall can be made in one piece with this technique.
