Abstract

In the case of a travelling mechanism (running gear) (1) for an extension arm (5) of a gondola (6), which is supported displaceably on a guide rail (4) by means of rollers (36, 37), the travelling mechanism (1) comprises a travelling-mechanism support (21) for the extension arm (5) and two or more U-shaped brackets (31) which engage over the guide rail (4). Furthermore, the brackets (31) are connected rotatably to the travelling-mechanism support (21) and are provided with the rollers (36, 37). By means of this configuration, it is possible to lay the guide rail (4) directly on the roof surface (3) of a building (2), and the guide rail (4) may also be arranged in an arcuate manner. By virtue of the articulated connection of the brackets (31) to the travelling-mechanism support (21), the travelling mechanism (1) can, in fact, turn curves without any lateral displacement movements of the rollers (36, 37) taking place. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Fahrwerk für einen Ausleger einer Gondel oder eines ähnlichen Aufnahme- oder Arbeitsgerätes, einen Kran oder dgl., das auf einer Führungsschiene mittels Laufrollen verfahrbar abgestützt ist.The invention relates to a chassis for a boom of a nacelle or a similar recording or working device, a crane or the like, which is movably supported on a guide rail by means of rollers.

Ein Fahrwerk dieser Art ist durch die DE-C2-28 45 874 bekannt. An einem starren Träger für zur Führung eines Hubseiles vorgesehenen Seilrollen sind hierbei in dessen Endbereichen Streben angebracht, mittels denen der Träger über Laufrollen an einer Führungsschiene abgestützt ist. Abgesehen davon, daß die Führungsschiene nicht auf einem Bauteil angeordnet werden kann, sondern mittels Halter schwebend aufzuhängen ist, da der Träger unterhalb von dieser verfahren wird, ist des weiteren von Nachteil, daß das in Form einer Laufkatze ausgebildete Fahrwerk in sich unbeweglich ist und die Laufrollen mit einem großen Abstand zueinander an dem Träger angeordnet sind. Für Kurvenfahrten ist dieses einfach gestaltete Fahrwerk demnach nicht geeignet bzw. es ist, sofern die Führungsschiene in Bögen mit großen Radien verlegt ist, ein seitliches Versetzen der Laufrollen in Kauf zu nehmen. Dies führt jedoch zu einem erheblichen Verschleiß. Der Anwendungsbereich dieses bekannten Fahrwerkes ist daher sehr begrenzt.A chassis of this type is known from DE-C2-28 45 874. In this case, struts are attached to a rigid support for cable pulleys provided for guiding a hoisting rope, by means of which struts are supported by means of which the support is supported on a guide rail via rollers. Apart from the fact that the guide rail cannot be arranged on a component, but has to be suspended by means of a holder, since the carrier is moved below it, it is also disadvantageous that the trolley, which is designed in the form of a trolley, is immovable in itself and that Rollers are arranged at a large distance from each other on the carrier. This simply designed undercarriage is therefore not suitable for cornering, or if the guide rail is laid in arches with large radii, it is one to accept lateral displacement of the rollers. However, this leads to considerable wear. The area of application of this known chassis is therefore very limited.

Aufgabe der Erfindung ist es somit, ein Fahrwerk der eingangs genannten Gattung derart auszugestalten, daß dieses nicht nur auf einer aufliegenden Führungsschiene verfahren werden kann und dabei zuverlässig abgestützt ist, sondern mit dem auch ohne Schwierigkeiten Kurvenfahrten ausgeführt werden können, ohne daß dabei die Laufrollen seitlich auf der Führungsschiene verschoben werden. Vielmehr soll erreicht werden, daß sich die Laufrollen selbsttätig auf den jeweiligen Verlauf der Führungsschiene ausrichten, so daß das Fahrwerk auch beim Durchfahren von Kurven mit kleinen Radien stets sicher durch die Führungsschiene geführt ist und ein seitliches Versetzen dabei nicht eintritt. Der dazu erforderliche Bauaufwand soll gering gehalten werden, dennoch soll stets ein störungsfreier Betrieb gewährleistet sein und es sollen auch hohe Kräfte von dem Fahrwerk aufgenommen und abgestützt werden können.The object of the invention is therefore to design a chassis of the type mentioned in such a way that it can not only be moved on an overlying guide rail and is reliably supported, but also with which cornering can be carried out without difficulty, without the rollers laterally be moved on the guide rail. Rather, it should be achieved that the rollers align themselves automatically on the respective course of the guide rail, so that the chassis is always safely guided through the guide rail even when driving through curves with small radii and lateral displacement does not occur. The construction effort required for this should be kept low, nevertheless trouble-free operation should always be guaranteed and high forces should also be able to be absorbed and supported by the chassis.

Bei einem Fahrwerk der vorgenannten Art wird dies gemäß der Erfindung dadurch erreicht, daß das Fahrwerk aus einem vorzugsweise balken- oder plattenförmig ausgebildeten Fahrwerksträger, an dem ein oder mehrere Ausleger befestigt sind, und zwei oder mehreren U- oder L-förmig gestalteten Bügel, die die Führungsschiene übergreifen, besteht, und daß die Bügel jeweils verdrehbar mit dem Fahrwerksträger verbunden und mit den mit der Führungsschiene zusammenwirkenden Laufrollen versehen sind.In a chassis of the aforementioned type, this is achieved according to the invention in that the chassis consists of a preferably beam-shaped or plate-shaped chassis carrier, to which one or more brackets are attached, and two or more U- or L-shaped brackets that overlap the guide rail, and that the brackets are each rotatably connected to the chassis beam and provided with the rollers cooperating with the guide rail.

Zweckmäßig ist es hierbei, die Bügel jeweils mittels eines auf deren Oberseite vorgesehenen und vertikal abstehenden Gelenkbolzens vorzugsweise über Wälzlager in einer in den Fahrwerksträger angeordneten Bohrung verdrehbar zu lagern und die Führungsschiene als im Querschnitt Doppel-T- oder U-förmig gestaltete Schiene auszubilden, wobei die an den Bügeln angebrachten Laufrollen zwischen die vertikalen Schenkel der Führungsschiene eingreifen und durch diese geführt sind.It is expedient here to mount the brackets in each case by means of a vertically projecting hinge pin provided on their upper side, preferably via roller bearings, in a bore arranged in the chassis support and to design the guide rail as a double-T or U-shaped rail in cross section, wherein the rollers attached to the brackets engage between the vertical legs of the guide rail and are guided through them.

Angebracht ist es ferner, die Bügel mit an den Stirnflächen der Schenkel der Führungsschiene anliegenden Führungsrollen zu versehen, die, um eine Dreipunkt-Abstützung zu ermöglichen, derart angeordnet sein sollten, daß an dem Bügel auf einer Seite der Führungsschiene, vorzugsweise auf der dem Ausleger zugekehrten Seite, zwei mit seitlichem Abstand zueinander angeordnete Führungsrollen und auf der gegenüberliegenden Seite eine mittig zu dem Bügel angeordnete Führungsrolle angebracht sind.It is also appropriate to provide the brackets with guide rollers which bear against the end faces of the limbs of the guide rail and which, in order to enable three-point support, should be arranged in such a way that on the bracket on one side of the guide rail, preferably on the arm facing side, two guide rollers arranged at a lateral distance from one another and on the opposite side a guide roller arranged centrally to the bracket are attached.

Damit besonders hohe Kräfte aufgenommen und abgestützt werden können, ist bei einem an dem Fahrwerksträger angebrachten Ausleger dieser mittels einer oder mehreren Stützrollen auf einer parallel zu der Führungsschiene angeordneten Stützschiene verfahrbar abzustützen, es ist aber zu dem gleichen Zweck auch möglich, einen der Schenkel des Bügels, vorzugsweise den dem Ausleger zugekehrten Schenkel, mit einer Verlängerung zu versehen, in deren Endbereich eine oder mehrere an einer parallel zu der Führungsschiene angeordneten Stützschiene anliegende Stützrollen angebracht sind.In order that particularly high forces can be absorbed and supported, in the case of an extension arm attached to the undercarriage, the latter is movably supported by means of one or more support rollers on a support rail arranged parallel to the guide rail, but it is also possible for the same purpose to have one of the legs of the bracket , preferably the leg facing the boom, to be provided with an extension, in the end region of which one or more support rollers are attached, which rest on a support rail arranged parallel to the guide rail.

Wird ein Fahrwerk gemäß der Erfindung ausgebildet, in dem ein Fahrwerksträger mit eine Führungsschiene übergreifenden Bügeln versehen wird, die gelenkig mit dem Fahrwerksträger verbunden und über Laufrollen an der Führungsschiene abgestüzt sind, so ist es nicht nur möglich, die Führungsschiene unmittelbar z. B. auf der Dachfläche eines Gebäudes zu verlegen, sondern diese kann auch bogenförmg angeordnet werden. Durch die gelenkige Verbindung der Bügel mit dem Fahrwerksträger kann nämlich das Fahrwerk ohne weiteres auch Kurven mit kleinen Radien durchfahren, ohne daß seitliche Verschiebebewegungen der Laufrollen, durch die diese beschädigt werden können, auftreten. Die Bügel passen sich vielmehr selbsttätig dem Verlaufd er Führungsschiene an, so daß stets eine sichere Führung des Fahrwerkes gegeben ist.If a running gear according to the invention is formed in which a running gear carrier is provided with brackets which overlap a guide rail, which are connected in an articulated manner to the running gear carrier and are supported on rollers on the guide rail, it is not only possible to directly guide the guide rail z. B. to lay on the roof surface of a building, but this can also be arranged arched. Because of the articulated connection of the brackets to the undercarriage, the undercarriage can also easily negotiate curves with small radii without lateral displacement movements of the rollers, which can damage them, occur. The brackets rather adapt automatically to the course of the guide rail, so that there is always safe guidance of the undercarriage.

Der Bauaufwand, mittels dem dies zu bewerkstelligen ist , ist äußerst gering, da das Fahrwerk lediglich aus dem Fahrwerksträger und zwei oder mehreren an diesem angelenkten Bügeln zusammengesetzt ist. Dennoch können, da die Bügel mittels der Laufrollen die Führungsschiene gewissermaßen hintergreifen, auch hohe Kippkräfte aufgenommen werden, ein zuverlässiger und störungsfreier Betrieb über einen langen Zeitraum ist demnach gewährleistet.The construction cost, by means of which this can be accomplished, is extremely low, since the undercarriage is only composed of the undercarriage support and two or more brackets articulated on it. Nevertheless, since the brackets engage behind the guide rail to a certain extent, high tilting forces can also be absorbed, so reliable and trouble-free operation over a long period of time is guaranteed.

Das in Figur 1 dargestellte und mit 1 bezeichnete Fahrwerk dient zum seitlichen Versetzen einer Gondel 6, die an der Frontseite eines Gebäudes 2 vorgesehen und mit Hilfe eines zweiarmigen Auslegers 5 gehalten ist. Das Fahrwerk 1 ist hierbei auf einer auf der Dachfläche 3 des Gebäudes 2 angeordneten Führungsschiene 4 abgestützt und durch ein Hub- und Zugseil 7, das über an dem Ausleger 5 angebrachte Seilrollen 8 und 9 geführt ist, seitlich verfahrbar. Mit Hilfe des Hub- und Zugseils 7 kann die Gondel 6, die Personen, um z. B. Reinigungsarbeiten an der Fassade des Gebäudes 2 vornehmen zu können, aufnehmen kann, auch in der Höhe verstellt werden.The chassis shown in FIG. 1 and designated 1 serves for the lateral displacement of a nacelle 6, which is provided on the front of a building 2 and is held with the aid of a two-armed boom 5. The undercarriage 1 is supported on a guide rail 4 arranged on the roof surface 3 of the building 2 and can be moved laterally by a lifting and pulling rope 7, which is guided over rope pulleys 8 and 9 attached to the boom 5. With the help of the lifting and pulling rope 7, the gondola 6, the people to z. B. To be able to carry out cleaning work on the facade of building 2, can also be adjusted in height.

Das Fahrwerk 1 ist aus einem Fahrwerkträger 21, der in Form eines Balkens 22 oder einer Platte ausgebildet ist, und zwei an diesen gelenkig angebrachten Bügeln 31 zusammengesetzt. Die U-förmig gestalteten Bügel 31 weisen einen Steg 32 sowie zwei von diesem abstehende Schenkel 33 und 34 auf, die die Führungsschiene 4 übergreifen. Als Führungsschiene 4 ist bei dem Ausführungsbeispiel nach den Figuren 1 bis 3 eine im Querschnitt Doppel-T-förmige Schiene 11 vorgesehen, zwischen deren von einem Mittelsteg 12 abstehenden Schenkeln 13 und 14 Laufrollen 36 und 37 eingreifen, die drehbar auf in die Schenkel 33 bzw. 34 der Bügel 31 eingesetzte Bolzen 38 bzw. 39 gelagert und somit durch die Schenkel 13 und 14 geführt sind.The undercarriage 1 is composed of an undercarriage support 21, which is designed in the form of a beam 22 or a plate, and two brackets 31 which are articulated thereon. The U-shaped bracket 31 have a web 32 and two legs 33 and 34 projecting therefrom which overlap the guide rail 4. 1 to 3, a cross-sectionally T-shaped rail 11 is provided as the guide rail 4, between the legs 13 and 14 of the rollers 36 projecting from a central web 12 and 37 engage, which are rotatably mounted on pins 38 and 39 inserted into the legs 33 and 34 of the brackets 31 and are thus guided through the legs 13 and 14.

Die Bügel 31 sind gelenkig mit dem Fahrwerksträger 21 verbunden, so daß das Fahrwerk 1 sich selbsttätig dem Verlauf der unmittelbar auf der Dachfläche 3 des Gebäudes angebrachten Führungsschiene 4 anpaßt und somit auch Kurven mit kleinen Radien sicher zu durchfahren sind. Dazu ist an den Stegen 32 der Bügel 31 jeweils ein nach oben abstehender Gelenkbolzen 35 vorgesehen, die in in die Platte 22 des Fahrwerksträgers 21 eingearbeitete Bohrungen 23 eingreifen und in diesen mittels Wälzlager 24 verdrehbar gelagert sind. Des weiteren sind an den Schenkeln 33 und 34 der Bügel 31 mittels Halter 43 und Lagerbolzen 44 abgestützte Führungsrollen 40 und 41 bzw. 42 vorgesehen, die an den Stirnflächen des Schenkels 14 der Schiene 11 anliegen. Auf diese Weise ist bei einer Dreipunktabstützung der Bügel 31 deren selbsttätiges Verschwenken gegenüber dem Fahrwerksträger 21 gewährleistet. Und da das Fahrwerk 1 mittels der an den Bügeln 31 angebrachten Laufrollen 36 und 37 die ortsfest angeordnete Führungsschiene 4 gewissermaßen hintergreift, könen auch hohe von der Gondel 6 ausgehende Zugkräfte abgestützt werden.The brackets 31 are articulated to the undercarriage support 21, so that the undercarriage 1 automatically adapts to the course of the guide rail 4 attached directly to the roof surface 3 of the building, and thus curves with small radii can also be passed safely. For this purpose, an upwardly projecting hinge pin 35 is provided on the webs 32 of the stirrups 31, which engage in bores 23 machined into the plate 22 of the undercarriage support 21 and are rotatably supported therein by means of roller bearings 24. Furthermore, on the legs 33 and 34 of the bracket 31 by means of holders 43 and bearing bolts 44 supported guide rollers 40 and 41 and 42 are provided, which bear against the end faces of the legs 14 of the rail 11. In this way, with a three-point support of the bracket 31, their automatic pivoting relative to the chassis carrier 21 is ensured. And since the undercarriage 1, as it were, engages behind the fixedly arranged guide rail 4 by means of the rollers 36 and 37 attached to the brackets 31, high tensile forces emanating from the nacelle 6 can also be supported.

Bei der Ausführungsvariante des Fahrwerkes 1' nach Figur 4 sind die beiden an dem Fahrwerksträger 21 angebrachten Arme des Auslegers 5' zusätzlich auf einer U-förmigen Stützschiene 15 abgestützt, die ebenfalls auf der Dachfläche 3 des Gebäudes 2 parallel zu der ebenfalls im Querschnitt U-förmig gestalteten für das Fahrwerk 1' vorgesehenen Schiene 11' verlaufend angeordnet ist.In the embodiment variant of the chassis 1 'according to FIG. 4, the two arms of the boom 5' attached to the chassis carrier 21 are additionally supported on a U-shaped support rail 15, which is also on the roof surface 3 of the building 2 parallel to the also in cross section U- Shaped rail 11 'provided for the chassis 1' is arranged to extend.

Dazu sind an den Armen des Auslegern 5' mittels Lagern 18 auf Bolzen 19 drehbar gelagerte Rollen 17 vorgesehen, die sich auf der Stützschiene 15 abwälzen.For this purpose, rollers 17 rotatably mounted on the arms of the arms 5 'by means of bearings 18 on bolts 19 are provided, which roll on the support rail 15.

Die gelenkig mit dem Fahrwerksträger 21 über Gelenkbolzen 35 verbundenen Bügel 31' sind bei diesem Ausführungsbeispiel winkelförmig gestaltet. Die an dem Schenkel 33' angebrachte Laufrolle 36' greift hierbei wiederum zwischen die beiden von dem Mittelsteg 12' abstehenden Schenkel 13' und 14' der Schiene 11' ein, die Führungsrollen 40, 41 und 42 liegen an der Stirnfläche des oberen Schenkels 14' und dem Mittelsteg 12' an. Mittels des unteren Schenkels 13' ist die Schiene 11' auf der Dachfläche 3 befestigt.The brackets 31 'which are articulated to the undercarriage 21 via hinge bolts 35 are angular in this embodiment. The roller 36 'attached to the leg 33' in turn engages between the two legs 13 'and 14' of the rail 11 'projecting from the central web 12', the guide rollers 40, 41 and 42 lie on the end face of the upper leg 14 ' and the central web 12 '. The rail 11 'is fastened on the roof surface 3 by means of the lower leg 13'.

Gemäß Figur 5 ist zur zusätzlichen Abstützung des Fahrwerkes 1'' an den Schenkeln 33' der Bügel 31' jeweils eine Verlängerung 45 vorgesehen, in deren Endbereichen eine oder mehrere Stützrollen 46 angeordnet sind. Des weiteren ist in die Stirnwand des Gebäudes 2 eine parallel zu der Führungsschiene 11' angeordnete Stützschiene 19 eingelassen, an der die Stützrollen 46 anliegen. Auf diese Weise sind ebenfalls hohe Kräfte abzustützen.According to FIG. 5, an extension 45 is provided for each additional support of the chassis 1 ″ on the legs 33 ′ of the brackets 31 ′, in the end regions of which one or more support rollers 46 are arranged. Furthermore, a support rail 19, which is arranged parallel to the guide rail 11 ′ and against which the support rollers 46 rest, is embedded in the end wall of the building 2. High forces must also be supported in this way.
