Definitions
- the shelters required for the maintenance and inspection of the facilities are temporarily made.
- elevator systems of this kind up to a delivery height of 3 m, as a rule, no safety-related acceptance by a named Job required, provided the manufacturer has appropriate manufacturer certificates.
- the lift height is the travel distance that the platform can cover at maximum.
- Simplified elevator systems of this type can be used in lift shafts, which i. d. R. bricked or concreted are mounted. In most applications, however, these systems are delivered with a hoistway scaffold. This can be mounted as a load-bearing or self-supporting shaft scaffolding indoors or outdoors.
- the load-bearing shaft framework construction consists of posts or longitudinal struts and bars in the form of steel profiles, usually hollow steel profiles.
- shaft scaffolds are often lined with glass, façade panels or other material.
- a drive system mainly spindle drives and hydraulic drive systems are offered on the elevator market.
- the drive spindle or the hydraulic ram and the guide system are mounted on a side wall or the rear wall.
- the elevator platforms are guided cantilevered on one side as a "backpack system”.
- the drive motor or the hydraulic unit is located either on the drive side behind a veneer (spindle drives) or outside the elevator shaft (hydraulic units).
- a side or rear wall is installed by the required technology (drive spindle, hydraulic ram, guide rails, etc.).
- This wall side can, if architecturally desired, be clad. In shear and crushing hazards by the driving motion such a wall cladding is mandatory. With glass elevators, the resulting reduced transparency is distracting.
- the clad wall side can also not be used for a possible car access and requires additional space.
- "backpack systems" in comparison to centrally suspended systems have poorer handling characteristics, which can be achieved, for example, by stick-slip effect. and resulting car vibrations during travel. Among other things, this leads to higher noise emissions, which in homes lead to impaired living comfort.

Description
Zugmitteleinrichtung für eine Aufzugsanlage, die in einem Schachtgerüst oder einem Fahrschacht angeordnet werden kann und zur Aufnahme eines Lastaufnahmemittels dient, das über mindestens eine mit einem Antriebsmotor verbundene, am Schachtgerüst oder am Fahrschacht gelagerte Antriebswelle und Tragmittel, insbesondere einer Zugmitteleinrichtung, im Schachtgerüst oder im Fahrschacht auf- und abwärts bewegt wird.Zugmitteleinrichtung for an elevator installation, which can be arranged in a shaft scaffold or a shaft and serves to receive a lifting device, which is connected via at least one connected to a drive motor, mounted on the shaft frame or on the shaft drive shaft and suspension means, in particular a traction means in the shaft frame or in the shaft is moved up and down.
Es sind bereits allgemein vereinfachte Aufzugsanlagen für Behinderte bekannt. Diese werden überwiegend in privaten Wohnbereichen zum barrierefreien Transport von Personen mit Behinderungen eingesetzt und sind im allgemeinen Sprachgebrauch unter dem Begriff "Homelift" bekannt.There are already generally simplified elevator systems for the disabled known. These are mainly used in private residential areas for the barrier-free transport of persons with disabilities and are known in common usage under the term "home lift".
Vereinfachte Aufzugsanlagen werden in Ermangelung einer harmonisierten europäischen Norm, die bisher nur in Form der prEN 81-41:2007 als Entwurf zur Prüfung und Stellungnahme der Öffentlichkeit vorliegt, beispielsweise in Deutschland in Anlehnung an die Forderungen der Richtlinie 2006/42/EG - auch Maschinenrichtlinie genannt - hergestellt und eingebaut. Diese Richtlinie erlaubt es z. B., durch Einsatz einer Todmannsteuerung, d. h. der Aufzug kann nur gefahren werden, solange eine Bedientaste manuell gedrückt wird, bei einer maximalen Betriebsgeschwindigkeit von 0,15 m/s und weiteren Maßnahmen, auf eine Kabinenabschlusstür zu verzichten. Weiterhin erlaubt die Maschinenrichtlinie reduzierte Über- (Schachtköpfe) und Unterfahrten (Schachtgruben) auszuführen.In the absence of a harmonized European standard, which has hitherto been available only in the form of prEN 81-41: 2007 as draft for examination and public opinion, for example in Germany following the requirements of Directive 2006/42 / EC - simplified Machinery Directive called - manufactured and installed. This guideline allows z. Example, by using a Todmannsteuerung, d. H. the lift can only be moved as long as an operating button is pressed manually, at a maximum operating speed of 0.15 m / s and other measures to dispense with a cabin door. Furthermore, the Machinery Directive allows reduced over- (shaft heads) and underpasses (shaft pits) to execute.
Die für die Wartung und Inspektion der Anlagen erforderlichen Schutzräume werden temporär hergestellt. Für Aufzugsanlagen dieser Art ist bis zu einer Förderhöhe von 3 m i. d. R. keine sicherheitstechnische Abnahme durch eine benannte Stelle erforderlich, sofern der Herstellerbetrieb über entsprechende Herstellerzertifikate verfügt. Die Förderhöhe ist der Fahrweg, den die Plattform maximal zurücklegen kann.The shelters required for the maintenance and inspection of the facilities are temporarily made. For elevator systems of this kind, up to a delivery height of 3 m, as a rule, no safety-related acceptance by a named Job required, provided the manufacturer has appropriate manufacturer certificates. The lift height is the travel distance that the platform can cover at maximum.
Vereinfachte Aufzugsanlagen dieser Art können in Aufzugsschächten, die i. d. R. gemauert oder betoniert sind, montiert werden. In den meisten Anwendungsfällen werden diese Anlagen jedoch mit einem Aufzugsschachtgerüst ausgeliefert. Dieses kann als tragendes oder selbsttragendes Schachtgerüst im Innen- oder im Außenbereich montiert werden. Die tragende Schachtgerüstkonstruktion besteht aus Pfosten bzw. Längsstreben und Riegeln in Form von Stahlprofilen, normalerweise Stahlhohlprofile. Damit eine zumindest über den Verfahrweg geschlossene Umwehrung entsteht, werden Schachtgerüste häufig mit Glas, Fassadenplatten oder anderem Material ausgekleidet.Simplified elevator systems of this type can be used in lift shafts, which i. d. R. bricked or concreted are mounted. In most applications, however, these systems are delivered with a hoistway scaffold. This can be mounted as a load-bearing or self-supporting shaft scaffolding indoors or outdoors. The load-bearing shaft framework construction consists of posts or longitudinal struts and bars in the form of steel profiles, usually hollow steel profiles. In order to create a barrier that is closed at least over the travel path, shaft scaffolds are often lined with glass, façade panels or other material.
Als Antriebssystem werden auf dem Aufzugsmarkt hauptsächlich Spindelantriebe und hydraulische Antriebssysteme angeboten. Hierbei werden auf eine Seitenwand oder die Rückwand die Antriebsspindel bzw. der Hydraulikstempel sowie das Führungssystem montiert. Die Aufzugsplattformen werden als "Rucksacksystem" einseitig auskragend geführt. Der Antriebsmotor bzw. das Hydraulikaggregat befindet sich entweder auf der Antriebsseite hinter einer Verblendung (Spindelantriebe) oder außerhalb des Aufzugsschachts (Hydraulikaggregate).As a drive system mainly spindle drives and hydraulic drive systems are offered on the elevator market. Here, the drive spindle or the hydraulic ram and the guide system are mounted on a side wall or the rear wall. The elevator platforms are guided cantilevered on one side as a "backpack system". The drive motor or the hydraulic unit is located either on the drive side behind a veneer (spindle drives) or outside the elevator shaft (hydraulic units).
Bei beiden Antriebssystemen wird eine Seiten- oder die Rückwand durch die erforderliche Technik (Antriebsspindel, Hydraulikstempel, Führungsschienen, etc.) verbaut. Diese Wandseite kann, wenn architektonisch gewünscht, verkleidet werden. Bei Scher- und Quetschgefahren durch die Fahrbewegung ist eine derartige Wandverkleidung zwingend erforderlich. Bei Glasaufzügen wird die dadurch reduzierte Transparenz als störend empfunden.In both drive systems, a side or rear wall is installed by the required technology (drive spindle, hydraulic ram, guide rails, etc.). This wall side can, if architecturally desired, be clad. In shear and crushing hazards by the driving motion such a wall cladding is mandatory. With glass elevators, the resulting reduced transparency is distracting.
Die verkleidete Wandseite kann außerdem nicht für einen möglichen Kabinenzugang genutzt werden und erfordert zusätzlichen Bauraum. Außerdem haben "Rucksacksysteme" im Vergleich zu zentral aufgehängten Systemen schlechtere Fahreigenschaften, was sich beispielsweise durch Ruckgleiten (Stick-Slip-Effekt) und daraus resultierenden Fahrkorbvibrationen während der Fahrbewegung äußert. Dies führt u. a. zu höheren Geräuschemissionen, die in Wohnhäusern zu Beeinträchtigungen des Wohnkomforts führen.The clad wall side can also not be used for a possible car access and requires additional space. In addition, "backpack systems" in comparison to centrally suspended systems have poorer handling characteristics, which can be achieved, for example, by stick-slip effect. and resulting car vibrations during travel. Among other things, this leads to higher noise emissions, which in homes lead to impaired living comfort.

Bei der Aufzugsanlage nach der
Ferner ist eine Zugmitteleinrichtung für eine Aufzugsanlage bekannt (
Der Erfindung liegt die Aufgabe zugrunde, das Schachtgerüst sowie die zugehörige Antriebsvorrichtung für eine Aufzugsanlage auf einfache und kostengünstige Weise bei optimaler Platzausnutzung herzustellen.The invention has for its object to produce the shaft scaffold and the associated drive device for an elevator system in a simple and cost-effective manner with optimal space utilization.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Zugmitteleinrichtung als Flaschenzug mit zwei oder mehreren, insbesondere mit vier, Umlenkscheiben, ausgestattet ist, deren Achsen auf einer in etwa vertikal verlaufenden Ebene untereinander angeordnet sind, wobei zumindest eine Umlenkscheibe im Fahrschacht oder am Schachtgerüst oberhalb der Aufzugsanlage, eine weitere Umlenkscheibe unterhalb der Aufzugsanlage im Fahrschacht oder am Schachtgerüst und eine oder mehrere, insbesondere zwei, Umlenkscheiben an einem Seitenelement des Lastaufnahmemittels, insbesondere Fahrplattform, gelagert sind. Da die als Zugmitteleinrichtung ausgebildete, nach dem Prinzip des Flaschenzugs arbeitende Einrichtung mit zwei oder mehreren, insbesondere mit vier, Umlenkscheiben ausgestattet ist, deren Achsen auf einer in etwa vertikal verlaufenden Ebene untereinander angeordnet sind, lässt sich die Zugmitteleinrichtung auf einem sehr kleinen Raum zwischen der Plattform und der Schachtwand, insbesondere im nahen Bereich der Seiteteile der Plattform, unterbringen. So kann die Fläche der Plattform optimal gestaltet und sehr groß gewählt werden. Eine oder mehrere, insbesondere zwei, der feststehenden Umlenkscheiben im Fahrschacht sind mit der oder den Antriebsachsen verbunden und bewegen das Lastaufnahmemittel auf- und abwärts.The object is achieved in that the Zugmitteleinrichtung is equipped as a pulley with two or more, especially four, deflecting discs, whose axes are arranged on an approximately vertical plane with each other, wherein at least one deflection pulley in the shaft or on the shaft frame above the Elevator installation, another deflection plate below the elevator installation in the lift shaft or at the shaft scaffold and one or more, in particular two, deflection disks are mounted on a side element of the load suspension device, in particular the travel platform. Since trained as Zugmitteleinrichtung, working on the principle of pulley device is equipped with two or more, especially four, deflection pulleys whose axes are arranged on an approximately vertical plane with each other, the Zugmitteleinrichtung can be in a very small space between the Platform and the shaft wall, especially in the near area of the side parts of the platform, accommodate. Thus, the surface of the platform can be optimally designed and chosen very large. One or more, in particular two, of the fixed deflecting disks in the driving shaft are connected to the drive shaft (s) and move the load receiving means up and down.
Dies wird dadurch erreicht, dass eine Verankerung für das Zugmittel des Flaschenzugs im Fahrschacht oder am Schachtgerüst oberhalb der Aufzugsanlage und eine weitere Verankerung für das Zugmittel des Flaschenzugs unterhalb der Aufzugsanlage im Fahrschacht oder am Schachtgerüst angeschlossen ist. Die Verankerungen befinden sich platzsparend in der gleichen vertikalen Ebene wie die Umlenkrollen. Im Unterschied zu herkömmlichen Anlagen muss so das Zugmittel nicht auf eine Trommel aufgewickelt werden oder mit einem Gegengewicht verbunden werden.This is achieved in that an anchorage for the traction means of the pulley in the shaft or on the shaft scaffold above the elevator installation and a further anchorage for the traction means of the pulley is connected below the elevator installation in the shaft or on the shaft framework. The anchorages are space-saving in the same vertical plane as the pulleys. In contrast to conventional systems so the traction means must not be wound on a drum or connected to a counterweight.
Vorteilhaft ist es, dass der Flaschenzug als Faktorenflaschenzug ausgebildet ist und zwei Flaschenzüge gegenüber dicht an zwei Seitenelementen des Lastaufnahmemittels, insbesondere einer Fahrplattform, vorgesehen sind.It is advantageous that the pulley is designed as a factor pulley and two pulleys against close to two side elements of the load-carrying means, in particular a driving platform, are provided.
Ferner ist es vorteilhaft, dass der Flaschenzug als Faktorenflaschenzug ausgebildet ist und zwei Flaschenzüge gegenüber dicht an zwei Seitenelementen des Lastaufnahmemittels, insbesondere einer Fahrplattform, vorgesehen sind und dass zumindest zwei Flaschenzüge im Bereich je einer Außenseite des Lastaufnahmemittels, insbesondere des Fahrkorbs oder der Fahrplattform der Aufzugsanlage, diagonal gegenüberliegend in zwei Eckbereichen der Aufzugsanlage vorgesehen sind.Further, it is advantageous that the pulley is designed as a factor pulley and two pulleys against close to two side elements of the lifting device, in particular a driving platform, are provided and that at least two pulleys in each area an outer side of the lifting device, in particular the car or the platform of the elevator system , Diagonally opposite are provided in two corner regions of the elevator system.
In weiterer Ausgestaltung der Erfindung ist es vorteilhaft, dass der Eckbereich durch zwei in etwa winklig zusammenlaufende Wände des Fahrschachts und einem Seitenelement gebildet wird, wobei das Seitenelement derart angeordnet ist, dass es zusammen mit den Wänden einen Freiraum bildet, der derart großflächig, insbesondere dreieckförmig, ausgebildet ist, dass im Eckbereich der vertikal ausgerichtete Flaschenzug angeordnet werden kann.In a further embodiment of the invention, it is advantageous that the corner region is formed by two approximately at an angle converging walls of the driving shaft and a side member, wherein the side member is arranged such that it forms a free space together with the walls, which is such a large area, in particular triangular , is formed so that in the corner region of the vertically oriented pulley can be arranged.
Vorteilhaft ist es auch, dass der Querschnitt des Schachtgerüsts und/oder des Lastaufnahmemittels, insbesondere die Fahrplattform, oval, rund, mehreckförmig, rechteckförmig vorzugsweise quadratisch ausgebildet ist und die den Enden der Antriebswellen zugeordneten Tragmittel der Zugmitteleinrichtung diagonal gegenüberliegend angeordnet sind und in unmittelbarer Nähe und parallel zu die Eckbereiche bildenden, vertikal verlaufenden Längsseiten des Schachtgerüsts verlaufen.It is also advantageous that the cross section of the shaft frame and / or the load receiving means, in particular the driving platform, oval, round, polygonal, rectangular preferably square and the ends of the drive shafts associated suspension means of Zugmitteleinrichtung diagonally opposite and are in the immediate vicinity and run parallel to the corner regions forming, vertically extending longitudinal sides of the shaft framework.
Da die Tragmittel, das Führungssystem und alle weiteren technischen Komponenten ausschließlich im Seitenbereich, insbesondere im Eckbereich, des Schachtgerüsts vorgesehen sind, wird im zentralen Bereich des Schachtgerüsts für das Lastaufnahmemittel, insbesondere für die Fahrplattform, ein sehr großer Freiraum geschaffen.Since the support means, the guide system and all other technical components are provided exclusively in the side area, in particular in the corner, the shaft framework, a very large clearance is created in the central region of the shaft frame for the load handling device, in particular for the driving platform.
Hierzu sind in vorteilhafter Weise die Eckbereiche der Fahrplattform, die an den Innenquerschnitt des Schachtgerüsts angepasst sind, abgeschnitten, sodass sich durch die beiden im Eckbereich zusammen laufenden Längsseiten des Schachtgerüsts und die gegenüberliegende Stirnkante der Fahrplattform, wenn diese eine rechteckförmige oder quadratische Grundfläche aufweist, ein in der Ansicht von oben dreieckförmiger Freiraum geschaffen wird, in dem das Tragmittel, das Führungssystem sowie das Bremssystem für die Fahrplattform optimal untergebracht werden können. Da die Dreiecksfläche sehr wenig Platz benötigt, um an dieser Stelle die Tragmittel zu platzieren, werden auch die Zugangsöffnungen zur Fahrplattform optimal vergrößert. Insgesamt erhält man auf kleinstem Raum eine optimale Raumausnutzung für die erforderliche Technik der Gesamtanlage. Auf diese Weise können mehr als 70 % der Aufstellfläche der Anlage für die Fahrplattform zur Verfügung gestellt werden. Die Verwendung einer quadratischen Plattform vereinfacht auch die Planung eines Architekten wesentlich, da er ohne Probleme einen derartigen Baukörper in einem Gebäude integrieren kann. Außerdem wird durch die erfindungsgemäße Einrichtung an allen vier Seiten an den Haltestellen ein optimaler Zugang zur Fahrplattform geschaffen. Für die Nutzung der Aufzugsanlage durch einen Rollstuhlfahrer bietet die quadratische Grundform der Fahrplattform eine optimale Wendemöglichkeit. Diese Bewegung findet kreisförmig statt, sodass die abgeschrägten Ecken der Kabinenwände nicht benötigt werden.For this purpose, the corner regions of the driving platform, which are adapted to the inner cross section of the shaft frame, cut off in an advantageous manner, so that by the two in the corner area running along the long sides of the shaft frame and the opposite end edge of the platform when this has a rectangular or square base, a triangular in the view is created from above, in which the support means, the guide system and the braking system for the driving platform can be optimally accommodated. Since the triangular area requires very little space to place the suspension elements at this point, the access openings to the driving platform are also optimally enlarged. Overall, you get in the smallest space optimal space utilization for the required technology of the entire system. In this way, more than 70% of the installation surface of the system can be made available for the driving platform. The use of a square platform also greatly simplifies the planning of an architect, since he can easily integrate such a building in a building. In addition, an optimal access to the driving platform is created by the device according to the invention on all four sides at the stops. For the use of the elevator system by a wheelchair user, the square basic shape of the platform provides an optimal turning possibility. This movement takes place in a circle, so that the beveled corners of the cabin walls are not needed.
Hierzu ist es vorteilhaft, dass sich zwischen den sich gegenüberliegenden Eckbereichen des Schachtgerüsts eine Antriebswelle oder zwei koaxial zueinander ausgerichtete Antriebswellen erstrecken, die mit dem Antriebsmotor in Wirkverbindung stehen, oder dass jede Antriebswelle mit je einem Antriebsmotor in Wirkverbindung steht. Die Antriebswelle kann in vorteilhafter Weise als einteilig durchlaufende Antriebswelle oder zweigeteilt ausgebildet sein bzw. können auch zwei Antriebswellen vorgesehen sein. In vorteilhafter Weise stützt sich die einteilige Antriebswelle an seinen beiden äußeren Enden am Schachtgerüst oder an den Wänden des Fahrschachts ab. Ist die Antriebswelle zweigeteilt, kann sie sich am äußeren Ende des Schachtgerüsts oder an den Wänden des Fahrschachts abstützen und mit ihren inneren Enden auf einer im oberen Bereich des Schachtgerüsts angeordneten Traverse abstützen, die auch zur Aufnahme des Antriebsmotors dient. Da in den beiden sich gegenüberliegenden Eckbereichen ein Freiraum geschaffen ist, können, wie bereits erwähnt, die Tragmittel mit den zugehörigen Umlenk- bzw. Treibscheiben, das Führungssystem der Fahrplattform sowie im Eckbereich bzw. in den Gerüstecken des Schachtgerüsts vorteilhaft und platzsparend vorgesehen werden. Ferner wird durch diese Maßnahme auch erreicht, dass die auf die Antriebswelle einwirkenden Biegemomente sehr klein gehalten werden können, sodass die Antriebswelle nicht so stark dimensioniert zu werden braucht wie bisher. Hierdurch können ebenfalls Materialkosten eingespart werden.For this purpose, it is advantageous that a drive shaft or two drive shafts aligned coaxially to one another extend between the oppositely lying corner regions of the shaft frame, which drive shafts are in operative connection with the drive motor, or in that each drive shaft is in operative connection with one drive motor each. The drive shaft may advantageously be formed as a single-piece continuous drive shaft or in two parts or may also be provided two drive shafts. Advantageously, the one-piece drive shaft is supported at its two outer ends on the shaft frame or on the walls of the driving shaft. If the drive shaft is split in two, it can be supported on the outer end of the shaft framework or on the walls of the driving shaft and supported with its inner ends on a arranged in the upper region of the shaft frame traverse, which also serves to accommodate the drive motor. As in the two opposite corner areas a free space is created, as already mentioned, the support means with the associated deflecting or traction sheaves, the guide system of the driving platform and in the corner area or in the framework corners of the shaft framework advantageously and space-saving. Furthermore, this measure also ensures that the bending moments acting on the drive shaft can be kept very small, so that the drive shaft does not need to be dimensioned as strongly as before. As a result, material costs can also be saved.
Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung der Erfindung, dass der Antriebsmotor eine Abtriebswelle aufweist, deren Rotationsachse in etwa rechtwinklig zu einer Rotationsachse der Antriebswelle des Tragmittels, insbesondere Zugmitteleinrichtung, angeordnet ist. Hierdurch erhält man eine optimale Raumausnutzung für die Antriebsaggregate.An additional possibility, according to a development of the invention, that the drive motor has an output shaft whose axis of rotation is arranged approximately at right angles to a rotational axis of the drive shaft of the support means, in particular traction means. This gives optimum space utilization for the drive units.
Ferner ist es vorteilhaft, dass das Lastaufnahmemittel eine Fahrplattform ist, die zumindest zwei im Stirnkantenbereich und/oder im Eckbereich der Fahrplattform aufrechtstehende Seitenelemente aufweist, die an die Tragmittel angeschlossen sind.Furthermore, it is advantageous for the load-receiving means to be a traveling platform which has at least two side elements which are upright in the end edge region and / or in the corner region of the driving platform and which are connected to the suspension elements.
Vorteilhaft ist es auch, dass das Tragmittel zwischen Seitenelementen der Fahrplattform und den Eckbereich bildenden Längsseiten des Schachtgerüsts angeordnet ist. Die vorteilhaft platzierten Seitenelemente ermöglichen optimal große Durchgangsöffnungen an allen vier Seiten der Fahrplattform. Gleichzeitig dienen sie auch als Schutzeinrichtung, da sie die in den Eckbereichen vorgesehenen Tragmittel abdecken und auf dem Lastaufnahmemittel, insbesondere der Fahrplattform, befindliche Personen schützen, da sie verhindern, dass diese mit den Tragmitteln in Berührung kommen.It is also advantageous that the suspension element is arranged between side elements of the traveling platform and the corner region forming longitudinal sides of the shaft framework. The advantageously placed side elements allow optimally large passage openings on all four sides of the drive platform. At the same time, they also serve as a protective device, since they cover the support means provided in the corner regions and protect persons located on the load-carrying means, in particular the traveling platform, since they prevent them from coming into contact with the suspension elements.
Es ist auch von Vorteil, dass die Zugmitteleinrichtung als Flaschenzug ausgebildet ist und eine oder mehrere Umlenkscheiben aufweist und alle Achsen der Umlenkscheiben in etwa auf einer vertikalverlaufenden Ebene untereinander angeordnet sind. Hierdurch lässt sich auf einfache platzsparende Weise der Flaschenzug im Eckbereich von Fahrplattform und Schachtgerüst unterbringen. Von besonderer Bedeutung ist für die vorliegende Erfindung, dass für die Zugmitteleinrichtung, insbesondere den Flaschenzug, als Zugmittel Ketten, Stahlseile oder Zahnriemen verwendet werden können. Die Zugmittel werden lediglich mit lösbaren Klemmhaltern in den Endlagen fixiert, sodass auf die bisher notwendigen Gegengewichte platz- und kostensparend verzichtet werden kann. Die Verwendung von Zahnriemen hat den Vorteil, dass sie sich auch nach längerem Einsatz nicht dehnen, keinen Schlupf aufweisen und geräuscharm eingesetzt werden können. Weiterhin sind Zahnriemen resistent gegen diverse Umwelteinflüsse wie sehr hohe oder niedrige Temperaturen, Sonneneinstrahlung, Feuchtigkeit etc. und müssen nicht gewartet werden.It is also advantageous that the Zugmitteleinrichtung is designed as a pulley and has one or more deflection pulleys and all axes of the deflection plates are arranged approximately on a vertically extending plane with each other. As a result, in a simple space-saving manner, the pulley can be accommodated in the corner area of the traveling platform and shaft frame. Of particular importance for the present invention that for the Zugmitteleinrichtung, in particular the pulley, chains, steel cables or timing belt can be used as traction means. The traction means are fixed only with releasable clamp holders in the end positions, so that the previously necessary counterweights can be dispensed with in a space-saving and cost-saving manner. The use of timing belts has the advantage that they do not stretch even after prolonged use, have no slippage and can be used quietly. Furthermore, timing belts are resistant to various environmental influences such as very high or low temperatures, sunlight, moisture, etc. and do not need maintenance.
Ferner ist es vorteilhaft, dass der Flaschenzug ein Übersetzungsverhältnis von 1:1, 2:1, 3:1, 4:1, 5:1 oder größer aufweist. Der vorteilhafte Einsatz eines Flaschenzugs mit dem entsprechenden Übersetzungsverhältnis und die Ausführung eines gewichtsreduzierten Lastaufnahmemittels in Form einer Plattform, bestehend aus einem Boden und einem umlaufenden Rahmen, ermöglichen es auch, auf Gegengewichte zu verzichten und die Antriebsleistungen dennoch gering zu halten. Bei einer Außenabmessung der Fahrplattform von ca. 1,4 x 1,4 m und dem entsprechenden Übersetzungsverhältnis von 2:1, einer geringen Fahrgeschwindigkeit und der geringen Masse der Fahrplattform, kommt der Antriebsmotor mit einer Antriebsleistung von lediglich ca. 2 kW aus. In vorteilhafter Weise kann auch eine Frequenzregelung eingesetzt werden und dadurch die drei Phasen, die der Antrieb benötigt, über die Frequenzregelung erzeugt und der Anlaufstrom reduziert werden. Die Aufzugsanlage lässt sich damit an herkömmliche Steckdosen anschließen.Furthermore, it is advantageous that the pulley has a transmission ratio of 1: 1, 2: 1, 3: 1, 4: 1, 5: 1 or greater. The advantageous use of a pulley with the appropriate gear ratio and the execution of a weight-reduced lifting device in the form of a platform, consisting of a bottom and a surrounding frame, also make it possible to dispense with counterweights and still keep the drive power low. With an outside dimension of the driving platform of approx. 1.4 x 1.4 m and the corresponding gear ratio of 2: 1, a low driving speed and the low mass of the driving platform, the drive motor achieves a drive power of only approx. 2 kW. Advantageously, a frequency control can be used and thereby generates the three phases required by the drive, via the frequency control and the starting current can be reduced. The elevator system can thus be connected to conventional sockets.
Vorteilhaft ist es auch, dass das Lastaufnahmemittel, insbesondere die Fahrplattform, mit Hilfe mindestens einer Führung, insbesondere einer am Schachtgerüst angeordneten Führungsschiene, im Schachtgerüst geführt ist, wobei die Führung zumindest in einem Eckbereich des Schachtgerüsts und/oder in unmittelbarer Nähe des Tragmittels, insbesondere des Flaschenzugs, angeordnet ist.It is also advantageous that the load receiving means, in particular the traveling platform, is guided in the shaft frame by means of at least one guide, in particular a guide rail arranged on the shaft frame, the guide being at least in a corner region of the shaft frame and / or in the immediate vicinity of the suspension element, in particular the pulley, is arranged.
Ferner ist es vorteilhaft, dass der Antriebsmotor mit der Antriebswelle in einem Schachtkopf des Schachtgerüsts oder in einer Schachtgrube angeordnet ist.Furthermore, it is advantageous that the drive motor is arranged with the drive shaft in a shaft head of the shaft framework or in a shaft pit.
Vorteilhaft ist es auch, dass eine oder mehrere Zugangsöffnungen auf der Fahrplattform mit Hilfe von Kabinenwänden und/oder Türen verschlossen werden können.It is also advantageous that one or more access openings on the platform can be closed by means of cabin walls and / or doors.
Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung der Erfindung, dass die aufrechtstehenden Seitenelemente der Fahrplattform derart im Eckbereich der Fahrplattform angeordnet sind, dass an mindestens vier Seiten eine freie Zugangsöffnung zur Fahrplattform vorhanden ist. Auf diese Weise lässt sich ein derart gestaltetes Schachtgerüst mit der an das Schachtgerüst angepassten Fahrplattform problemlos auch an vorhandenen Gebäuden freistehenden anbauen oder nachträglich ohne große Umbauarbeiten im Gebäude integrieren.An additional possibility is, according to a development of the invention, that the upright side elements of the driving platform are arranged in the corner region of the driving platform such that a free access opening to the driving platform is present on at least four sides. In this way, a shaft scaffolding designed in this way with the traveling platform adapted to the shaft scaffold can also be easily attached to existing buildings free-standing or subsequently integrated into the building without major alterations.
Je nach Wunsch können die Zugangsöffnungen auf der Fahrplattform, wenn sie nicht benötigt werden, mit einer Kabinenwand versehen werden. An diese Kabinenwand gibt es keine höheren Anforderungen an die Festigkeit. Die Kabinenwand kann filigran ausgeführt sein, sodass eine Glaswand zur Ausführung kommen kann.If desired, the access openings on the drive platform can be provided with a cabin wall when not needed. There are no higher demands on the strength of this cabin wall. The cabin wall can be filigree, so that a glass wall can be executed.
Wird auf die Kabinenwände verzichtet oder werden diese in Glas ausgeführt und wird weiterhin das Schachtgerüst auf allen Seiten mit einer Glasverkleidung versehen, entsteht eine architektonisch ansprechende Ausführung mit einer maximal möglichen Transparenz.If the cabin walls are omitted, or if they are made of glass, and if the shaft framework is also provided with glass cladding on all sides, this results in an architecturally appealing design with maximum possible transparency.
Nach einer anderen Ausführungsform ist es vorteilhaft, dass das Schachtgerüst aus mindestens zwei diagonal gegenüberliegenden, vertikal verlaufenden Pfosten besteht, an denen die Tragmittel Führungsschienen und zumindest eine obere und eine untere Umlenkscheibe mittel- oder unmittelbar angeordnet sind und dass das Schachtgerüst und/oder die diagonal gegenüberliegenden, vertikal verlaufenden Pfosten und/oder die Traverse im Eckbereich des Schachtgerüsts mittel- oder unmittelbar an zumindest eine Innenwand des Fahrschachts angeschlossen ist. Hierdurch erhält man eine sehr kostengünstige Aufzugsanlage, die sich leicht in einem Fahrschacht einbauen lässt.According to another embodiment, it is advantageous that the shaft framework consists of at least two diagonally opposite, vertically extending posts on which the support means guide rails and at least one upper and one lower deflection plate are arranged directly or indirectly and that the shaft framework and / or diagonally opposite, vertically extending posts and / or the traverse in the corner of the shaft frame medium or directly connected to at least one inner wall of the driving shaft is. This gives a very inexpensive elevator system that can be easily installed in a lift shaft.
Nach einer anderen Ausführungsform ist es vorteilhaft, dass die Zugmitteleinrichtung für eine im Schachtgerüst einbaubare Aufzugsanlage, die freistehend und/oder in einem Fahrschacht angeordnet werden kann und zur Aufnahme eines Lastaufnahmemittels dient, das über mindestens eine mit mindestens einem Antriebsmotor verbundene am Schachtgerüst gelagerte Antriebswelle mit Hilfe von Tragmitteln, insbesondere einer Zugmitteleinrichtung, im Schachtgerüst aufund abwärts bewegt wird. Hierzu ist die Zugmitteleinrichtung als Flaschenzug, insbesondere Faktorenflaschenzug, mit zwei oder mehreren, insbesondere mit vier, Umlenkscheiben, ausgestattet, deren Achsen in etwa auf einer vertikalverlaufenden Ebene untereinander angeordnet sind, wobei zumindest eine Umlenkscheibe im Fahrschacht oder im Schachtgerüst oberhalb der Aufzugsanlage, eine weitere Umlenkscheibe unterhalb der Aufzugsanlage im Fahrschacht oder im Schachtgerüst und eine oder mehrere, insbesondere zwei, Umlenkscheiben am Schachtgerüst gelagert sind, wobei eine Verankerung für das Zugmittel des Flaschenzugs im Fahrschacht oder im Schachtgerüst oberhalb der Aufzugsanlage und eine weitere Verankerung für das Zugmittel des Flaschenzugs unterhalb der Aufzugsanlage an die Verankerung im Fahrschacht oder im Schachtgerüst angeschlossen ist.According to another embodiment, it is advantageous that the traction means for a can be installed in the pit scaffold lift system, which can be arranged free-standing and / or in a lift shaft and serves to receive a load receiving means, the at least one connected to at least one drive motor mounted on the shaft frame drive shaft Help of suspension elements, in particular a Zugmitteleinrichtung is moved up and down the shaft framework. For this purpose, the Zugmitteleinrichtung pulley, especially factor pulley, with two or more, in particular four, deflection, equipped, whose axes are arranged approximately on a vertically extending plane with each other, wherein at least one deflection pulley in the shaft or in the shaft frame above the elevator system, another Deflection pulley are mounted below the elevator installation in the lift shaft or in the shaft frame and one or more, in particular two, deflection disks on the shaft frame, wherein an anchorage for the traction means of the pulley in the lift shaft or in the shaft frame above the elevator installation and a further anchoring for the traction means of the pulley below Elevator system is connected to the anchorage in the lift shaft or in the shaft scaffold.
Vorteilhaft ist es auch, dass das Tragmittel, insbesondere der Zahnriemen, bei allen Umlenkscheiben nur in einer Richtung gebogen ist. Hierdurch braucht der Zahnriemen auch nur an einer Seite mit Zähnen ausgestattet zu sein, sodass die Standzeit des Zahnriemens wesentlich erhöht werden kann. Anstelle des Zahnriemens können, wie bereits erwähnt, auch anders ausgebildete Zugmittel z. B. Keilriemen eingesetzt werden.It is also advantageous that the suspension element, in particular the toothed belt, is bent only in one direction in all deflecting disks. As a result, the toothed belt also needs to be provided with teeth on only one side, so that the service life of the toothed belt can be substantially increased. Instead of the toothed belt, as already mentioned, also differently trained traction means z. B. V-belts are used.
Eine Kostenersparnis erreicht man auch dadurch, dass die beiden diagonal gegenüberliegenden Führungsschienen, ähnlich wie die Traverse, direkt und/oder mit Hilfe einer Halterung an den Schachtwänden bzw. an der Innenwand des Fahrschachts befestigt sind.A cost saving can be achieved also by the fact that the two diagonally opposite guide rails, similar to the traverse, are fastened directly and / or with the aid of a holder to the shaft walls or to the inner wall of the driving shaft.
Weitere Vorteile und Einzelheiten der Erfindung sind in den Patentansprüchen und in der Beschreibung erläutert und in den Figuren dargestellt.Further advantages and details of the invention are explained in the patent claims and in the description and illustrated in the figures.

Die obere Sektion 106 des Aufzugsschachtgerüstes 102 ist auf der Stockwerksdecke 116 angeordnet. Auf diese Weise kann das Schachtgerüst 102 von Etage zu Etage oder, bei entsprechend großer Öffnung, als durchgehende Konstruktion angeordnet werden.

Das Lastaufnahmemittel 200 bzw. die im Ausführungsbeispiel quadratisch ausgebildete Fahrplattform weist zumindest zwei im Stirnkantenbereich und/oder in einem Eckbereich 105 der Fahrplattform 200 zwei diagonal gegenüberliegende aufrechtstehende Seitenelemente 202 auf, die an Tragmittel 208 angeschlossen sind. Das Tragmittel 208 kann eine Seilzuganordnung oder eine nach dem Prinzip eines Flaschenzugs 209 arbeitende Seilzuganordnung sein.The load-receiving means 200 or the drive platform of square design in the exemplary embodiment has at least two in the end edge region and / or in a
Mit Hilfe des Flaschenzugs 209 kann der Betrag der aufzubringenden Kraft, z. B. zum Bewegen der Aufzugslast, verringert werden. Der Flaschenzug besteht aus festen und/oder losen Umlenkscheiben bzw. Rollen und einem Zugmittel bzw. einem Seil. Der Zahnriemenzug verfolgt das selbe Prinzip, nur dass hier anstelle eines Seils ein Zahnriemen verwendet wird. Bei dem hier eingesetzten Seilzug bzw. Flaschenzug 209 werden erfindungsgemäß zwei feststehende Verankerungen 216 und 218 verwendet. Für die Zugkraft entscheidend ist aber immer die Anzahl der tragenden Seile, auf die sich die Last verteilt. In der abgebildeten Grundform des Flaschenzugs ist die Spannung σ an jeder Stelle des Seils gleich. Die Gewichtskraft FL der Masse wird daher gleichmäßig auf alle n-Verbindungen zwischen den unteren und den oberen Rollen sowie den tragenden Seilen verteilt. Die Zugkraft am Ende des Seils ist proportional zur Spannung im Seil und somit gilt: Fz = Fl/n = mg/n.With the help of the
Der erfindungsgemäße Flaschenzug 209 kann ein Übersetzungsverhältnis von 1:1, 2:1, 3:1, 4:1, 5:1 oder größer aufweisen. Auf diese Weise kann unter anderem auf ein Gegengewicht verzichtet werden.The
Die beiden diagonal gegenüberliegenden Seitenelemente 202 sind an ihrem oberen Ende über einen oberen Querträger 203 miteinander verbunden. Außer den beiden diagonal gegenüberliegenden Seitenelementen 202 weist das Lastaufnahmemittel, insbesondere die Fahrplattform 200, keine weiteren Seitenteile auf. Auf diese Weise erhält man vier freie Zugangsöffnungen 128. Nach einer anderen Ausführungsform gemäß
Das Lastaufnahmemittel, insbesondere die Fahrplattform 200, ist mit Hilfe mindestens einer Führung, insbesondere einer am Schachtgerüst 102 angeordneten Führungsschiene 220 (

Das Schachtgerüst 102 besteht aus vier rechtwinklig zueinander ausgerichteten, vertikal verlaufenden Längsseiten 109, 111, 113 und 115. Eine jede Längsseite 109, 111, 113 und 115 besteht aus einem rechteckförmigen Rahmen mit Pfosten bzw. Längsstreben 129, die über mehrere Querstreben bzw. Riegel 201 miteinander fest verbunden sein können. Die mittlere Querstrebe 201 kann je nach Ausführungsform entfallen, sodass eine jede Längsseite 109, 111, 113 und 115 auch eine freie Zugangsöffnung 128 zum Lastaufnahmemittel, insbesondere zu der Fahrplattform, aufweist.The
