Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Lageänderung einer Gondel oder eines ähnlichen Aufnahme- oder Arbeitsgerätes, die mittels eines beispielsweise auf einer Führungschiene abgestützten Fahrwerkes oder eines Auslegers vertikal verstellbar aufgehängt ist.The invention relates to a device for changing the position of a nacelle or a similar recording or working device, which is suspended in a vertically adjustable manner by means of, for example, a running gear supported on a guide rail or a boom.

Durch die DE-AS 24 04 294 ist ein längs einer Dachkante verfahrbarer Wagen mit einem Ausleger und daran aufgehängter Gondel bekannt. Auf diese Weise ist es zwar möglich, die Gondel durch Verfahren des Wagens seitlich zu versetzen und durch Längenänderungen der diese tragenden Seile die Gondel anzuheben oder abzusenken, so daß z. B. zum Reinigen einer Fassade nahezu jede Stelle erreichbar ist, die Zuführung der Energie zu dem verfahrbaren Wagen ist aber oftmals mit erheblichen Schwierigkeiten verbunden. Meist muß nämlich ein Kabel mitgeschleppt und, um Beschädigungen durch die Laufräder zu vermeiden, vielfach in besonderer Weise geführt werden, oder es sind sehr störanfällige Schleifleitungen auf dem Dach des Gebäudes zu verlegen. Auch ist bei der bekannten Vorrichtung ein groß bauender Ausleger erforderlich, damit die Gondel vor der Dachkante aufgehängt werden kann. Des weiteren ist von Nachteil, daß der mit dem Ausleger und mindestens zwei Antriebsmotoren bestückte Wagen ein hohes Eigengewicht aufweist, das von dem entsprechend auszulegenden Bauwerk aufzunehmen ist, und daß dieser oftmals nur unter Schwierigkeiten an Dachaufbauten vorbei und um Kurven zu fahren ist. Der Einsatzbereich dieser bekannten Ausgestaltung ist somit sehr begrenzt.From DE-AS 24 04 294 a carriage that can be moved along a roof edge with a boom and a gondola suspended from it is known. In this way, it is possible to move the gondola laterally by moving the carriage and to raise or lower the gondola by changing the length of the ropes carrying it, so that, for. B. for cleaning a facade almost every point is accessible, but the supply of energy to the movable carriage is often associated with considerable difficulties. Usually, a cable has to be dragged along and, in order to avoid damage from the running wheels, it often has to be routed in a special way, or there are very fault-prone conductor lines to be laid on the roof of the building. In the known device, a large boom is required the gondola can be hung in front of the roof edge. Another disadvantage is that the car equipped with the boom and at least two drive motors has a high weight, which is to be absorbed by the structure to be designed accordingly, and that this is often difficult to get past roof structures and around curves. The area of use of this known configuration is therefore very limited.

Aufgabe der Erfindung ist es daher, eine Vorrichtung zur Lageänderung einer Gondel zu schaffen, die nicht nur äußerst vielseitig einsetzbar ist, sondern die auch klein baut und einen geringen Bauaufwand erfordert und somit wirtschaftlich hergestellt werden kann. Vor allem aber soll erreicht werden, daß die zum Verfahren des Fahrwerkes und zur Höhenverstellung der Gondel erforderlichen Antriebsglieder stationär angeordnet werden können, so daß die Zuführung der Energie zu diesen problemlos zu bewerkstelligen und Schleppkabel oder Schleifleitungen nicht notwendig sind, aber dennoch soll eine hohe Betriebssicherheit bei einfacher Handhabung gegeben sein.The object of the invention is therefore to provide a device for changing the position of a gondola, which is not only extremely versatile, but also has a small size and requires little construction and can therefore be produced economically. Above all, however, the aim is to ensure that the drive elements required for moving the undercarriage and for adjusting the height of the nacelle can be arranged in a stationary manner, so that the supply of energy to them can be accomplished without problems and trailing cables or conductor lines are not necessary, but high operational reliability is nevertheless intended be given with simple handling.

Gemäß der Erfindung ist die Vorrichtung zur Lageänderung einer Gondel oder dgl. der eingangs genannten Art, mittels der dies zu erreichen ist, dadurch gekennzeichnet, daß zur vertikalen und/oder horizontalen Verstellung der Gondel zwei mit Abstand zueinander angeordnete Antriebsglieder vorgesehen sind, die jeweils ein flexibles vorzugsweise durch diese aufrollbares Zugglied aufweisen, daß die Antriebsglieder ortsfest an einem das Fahrwerk tragenden Bauwerk, an der Gondel oder dem Fahrwerk angebracht und deren Zugglieder mit ihren freien Enden an der Gondel, dem Bauwerk oder dem Fahrwerk befestigt sind und daß die Antriebsglieder einzeln oder gemeinsam gleichsinnig oder gegenläufig zueinander gesteuert antreibbar sind.According to the invention, the device for changing the position of a gondola or the like. Of the type mentioned above, by means of which this can be achieved, characterized in that two spaced-apart drive elements are provided for vertical and / or horizontal adjustment of the gondola, each one Flexible, preferably by this rollable tension member that the drive members fixed to a structure supporting the chassis, attached to the gondola or the chassis and the tension members with their free Ends are attached to the nacelle, the structure or the chassis and that the drive elements can be driven individually or together in the same direction or in opposite directions in a controlled manner.

Zweckmäßig ist es hierbei, die Zugglieder durch Zugseile oder Ketten zu bilden, die mittels vorzugsweise jeweils zweier an dem Fahrwerk senkrecht zueinander angeordneter Umlenkrollen oder dgl. von der Horizontalen in die Vertikale übergeführt sind.It is expedient here to form the tension members by tension cables or chains, which are preferably transferred from the horizontal to the vertical by means of preferably two deflection rollers or the like arranged perpendicular to one another on the undercarriage.

Als Antriebsglieder sollten umsteuerbare elektrische Getriebemotore vorgesehen werden, die jeweils eine Seil- oder Kettentrommel zur Aufnahme der Zugseile oder Ketten aufweisen, es ist aber auch möglich, als Antriebsglieder jeweils eine Treibscheibe, eine Durchzugswinde oder ein Spill, vorzugsweise mit zugeordnetem Antriebsmotor, zu verwenden.Reversible electric geared motors should be provided as drive elements, each of which has a rope or chain drum for receiving the pulling cables or chains, but it is also possible to use a traction sheave, a pulling winch or a capstan, preferably with an associated drive motor, as drive elements.

Nach einer bevorzugten Ausführungsform sollten die Antriebsglieder beiderseits einer für das Fahrwerk vorgesehenen Führungsschiene angeordnet und die Gondel an den freien Enden der Zugglieder aufgehängt sein.According to a preferred embodiment, the drive links should be arranged on both sides of a guide rail provided for the running gear and the nacelle should be suspended from the free ends of the tension links.

Ferner ist es auch möglich, die beiden Antriebsglieder an der Gondel anzubringen und die Zugglieder mit ihren freien Enden in den Endbereichen einer für das Fahrwerk vorgesehenen Führungsschiene an dem Bauwerk zu befestigen.Furthermore, it is also possible to attach the two drive members to the nacelle and to fasten the free end of the tension members to the structure in the end regions of a guide rail provided for the running gear.

Nach weiteren Ausführungsvarianten kann ein Antriebsglied in einem Endbereich einer für das Fahrwerk vorgesehenen Führgungsschiene oder an der Gondel und das andere Antriebsglied in dem anderen Endbereich der Führungsschiene oder an dem Fahrwerk angeordnet sein, und an dem Zugglied des einen Antriebsgliedes kann die Gondel aufgehängt oder dessen freies Ende kann im Endbereich der Führungsschiene an dem Bauwerk befestigt bzw. das andere Zugglied kann mit seinem freien Ende an dem Fahrwerk oder im Endbereich der Führungsschiene an dem Bauwerk befestigt werden.According to further embodiment variants, a drive member can be in one end region of a guide rail provided for the running gear or on the nacelle and the other drive member can be in the other end region of the guide rail or be arranged on the undercarriage, and on the tension member of one drive member the gondola can be suspended or its free end can be attached to the structure in the end region of the guide rail or the other tension member can be attached to the undercarriage or in the end region of the guide rail with its free end be attached to the building.

Die Gondel kann aber auch mittels der Zugglieder an einem Traggestell als Ausleger aufgehängt werden, das an dem Bauwerk unmittelbar oder über Zwischenglieder abgestützt oder - als mobile Einheit - auf einer verfahrbaren Arbeitsschiene angeordnet ist.The gondola can also be suspended by means of the tension members on a support frame as a cantilever, which is supported on the structure directly or via intermediate links or - as a mobile unit - is arranged on a movable work rail.

Wird eine Vorrichtung zur Lageänderung einer Gondel gemäß der Erfindung ausgebildet, so ist es möglich, eine über Zugglieder mit den zugeordneten Antriebsgliedern trieblich verbundene Gondel sowohl seitlich zu verfahren als auch in der Höhe zu verstellen, ohne daß dazu besondere Vorkehrungen zu treffen sind oder ein größerer Aufwand zur Zuführung der Energie erforderlich ist. Nach einer bevorzugten Ausgestaltung können nämlich beide Antriebsglieder stationär angeordnet werden, so daß diesen die notwendige Energie, ohne daß dies Schleppkabel oder Schleifleitungen bedingt, ohne Schwierigkeiten zuzuführen ist, dennoch kann mit Hilfe der in entsprechender Weise zu steuernden Antriebsglieder die Gondel beliebig in der dieser zugeordneten Ebene verstellt werden. Bei Verwendung der vorschlagsgemäßen Vorrichtung als Fassadenreinigungsgerät kann demnach nahezu jede Stelle einer Gebäudefassade in kurzer Zeit erreicht werden.If a device for changing the position of a gondola is designed according to the invention, it is possible to move a gondola which is connected to the associated drive members via pulling members, as well as to adjust the height without taking any special precautions or a larger one Effort to supply the energy is required. According to a preferred embodiment, namely, both drive elements can be arranged in a stationary manner, so that the necessary energy can be supplied to them without difficulty, without this requiring trailing cables or conductor lines, nevertheless, with the aid of the drive elements to be controlled in a corresponding manner, the nacelle can be arbitrarily assigned to it Level can be adjusted. When using the proposed device as a facade cleaning device, almost any point on a building facade can be reached in a short time.

Da aufgrund der erfindungsgemäßen Ausgestaltung das Fahrwerk klein bemessen werden kann, ist dieses unmittelbar an einer Dachkante und auch um Kurven mit kleinen Radien zu verfahren. Und da lediglich das Fahrwerk und die an diesem aufgehängte Gondel zu verstellen sind, nicht aber die Antriebsglieder, ist der dazu benötigte Energieaufwand gegenüber der bekannten Ausgestaltung erheblich reduziert. Bei hoher Betriebssicherheit und einfacher Handhabung ist die vorschlagsgemäße Vorrichtung demnach, zumal auch Steigungen ohne weiteres befahren werden können, in vielseitiger und vorteilhafter Weise verwendbar.Since the chassis can be dimensioned small due to the design according to the invention, this is directly on a roof edge and also around curves with small radii to proceed. And since only the undercarriage and the nacelle suspended from it can be adjusted, but not the drive elements, the energy expenditure required for this is considerably reduced compared to the known design. With a high level of operational safety and simple handling, the proposed device can therefore be used in a versatile and advantageous manner, especially since inclines can also be negotiated without difficulty.

Die in den Figuren 1 bis 6 dargestellte und mit 1 bezeichnete Vorrichtung ist an einem Bauwerk 2 angebracht und dient zur Verstellung einer Gondel 10 in vertikaler und horizontaler Richtung, um beispielsweise die Fassade 3 des Bauwerkes 2 leicht reinigen zu können. Die Vorrichtung 1 besteht hierbei im wesentlichen aus einer an dem Bauwerk 2 mittels Haltern 12 befestigten Führungsschiene 11, einem auf diesem verfahrbaren Fahrwerk 13 sowie zwei Antriebsgliedern 21 und 31, die über Zugglieder 22 und 23 mit der Gondel 10 in Triebverbindung stehen. Das Fahrwerk 13 ist mittels Laufrollen 14 auf der im Querschnitt T-förmigen Führungsschiene 11 abgestützt.The device shown in FIGS. 1 to 6 and designated 1 is attached to a building 2 and is used to adjust a gondola 10 in the vertical and horizontal direction, for example around the facade 3 the building 2 can be cleaned easily. The device 1 consists essentially of a guide rail 11 fastened to the structure 2 by means of holders 12, a carriage 13 movable on the latter and two drive members 21 and 31 which are in drive connection with the nacelle 10 via tension members 22 and 23. The carriage 13 is supported by rollers 14 on the cross-sectionally T-shaped guide rail 11.

Als Antriebsglieder 21 und 31 sind hierbei Elektromotore 23 bzw. 33 vorgesehen, die jeweils mit einem Getriebe 24 bzw. 34 ausgestattet sind. Und mit den Getrieben 24 bzw. 34 sind Seiltrommeln 25 bzw. 35 gekoppelt, auf denen die aus Zugseilen 26 bzw. 36 bestehenden Zugglieder 22 bzw. 32 aufgerollt werden können. Über Umlenkrollen 15, 16 und 17 bzw. 18, 19 und 20 werden die Zugseile 26 bzw. 36 zwischen den Seiltrommeln 25 bzw. 35 und der Gondel 10, die somit an den Zugseilen 26, 36 aufgehängt ist, geführt. Die Elektromotore 23 und 33 sind einzeln oder gemeinsam gleichsinnig oder gegenläufig antreibbar.Electric motors 23 and 33 are provided as drive elements 21 and 31, each of which is equipped with a gear 24 or 34. And with the gearboxes 24 and 34, cable drums 25 and 35 are coupled, on which the tension members 22 and 32 consisting of pull cables 26 and 36 can be rolled up. The pulling cables 26 and 36 are guided between the cable drums 25 and 35 and the nacelle 10, which is thus suspended from the pulling cables 26, 36, via deflection rollers 15, 16 and 17 or 18, 19 and 20. The electric motors 23 and 33 can be driven individually or together in the same direction or in opposite directions.

Um die Höhenlage der Gondel 10 bei der Ausführungsvariante nach Figur 1 zu verändern, sind die beiden Elektromotore 23 und 33 gegenläufig anzutreiben. Je nach Drehrichtung der Seiltrommeln 25 und 35 werden somit die Zugseile 26 und 36 aufgerollt oder abgespult, so daß die Gondel 10 angehoben oder abgesenkt wird. Werden dagegen die Elektromotore 23 und 33 gleichsinnig angetrieben und die Seiltrommeln 25 und 35 mit gleicher Winkelgeschwindigkeit verdreht, so wird das Fahrwerk 13 auf der Führungsschiene 11 je nach Drehrichtung nach rechts oder links verfahren. Selbstverständlich ist es aber auch möglich, die Seiltrommeln 25 und 35 mit gleicher Drehrichtung aber unterschiedlichen Winkelgeschwindigkeiten anzutreiben, die Gondel 10 wird in diesem Falle seitlich versetzt und gleichzeitig angehoben oder abgesenkt.In order to change the height of the nacelle 10 in the embodiment variant according to FIG. 1, the two electric motors 23 and 33 are to be driven in opposite directions. Depending on the direction of rotation of the cable drums 25 and 35, the pull cables 26 and 36 are thus rolled up or unwound, so that the nacelle 10 is raised or lowered. If, on the other hand, the electric motors 23 and 33 are driven in the same direction and the cable drums 25 and 35 are rotated at the same angular velocity, the carriage 13 is moved to the right or left on the guide rail 11, depending on the direction of rotation. Of course, it is also possible to drive the cable drums 25 and 35 with the same direction of rotation but different angular velocities, in this case the nacelle 10 is laterally offset and at the same time raised or lowered.

Bei der Ausgestaltung nach Figur 2 sind die beiden Antriebsglieder 21 und 31 an der Gondel 10 angebracht und die freien Enden der Zugglieder 22 und 32 sind über Anlenkungen 27 bzw. 37 an dem Bauwerk 2 befestigt. Durch gesteuerten Antrieb der Antriebsglieder 21 und 31 kann somit in gleicher Weise das Fahrwerk 13 auf der Führungsschiene 11 verfahren und/oder die Höhenlage der Gondel 10 verändert werden.In the embodiment according to FIG. 2, the two drive members 21 and 31 are attached to the nacelle 10 and the free ends of the tension members 22 and 32 are attached to the structure 2 via articulations 27 and 37, respectively. Controlled drive of the drive members 21 and 31 can thus move the carriage 13 on the guide rail 11 in the same way and / or change the height of the nacelle 10.

Gemäß Figur 3 ist das Zugglied 22 des Antriebsgliedes 21 mittels einer Anlenkung 27' an dem Fahrwerk 13 befestigt. Mit Hilfe des Antriebsgliedes 21, das gemäß Figur 4 aber auch auf dem Fahrwerk 13 angeordnet sein kann, wobei das freie Ende des Zuggliedes 22 über die Anlenkung 27 an dem Bauwerk 2 befestigt ist, wird somit das Fahrwerk 13 auf der Führungsschiene 11 verfahren, die Höhenlage der Gondel 10 wird dagegen mittels des Antriebsgliedes 31, das über das Zugglied 32 mit der Gondel 10 in Triebverbindung steht, verändert.According to FIG. 3, the tension member 22 of the drive member 21 is fastened to the chassis 13 by means of a linkage 27 '. With the help of the drive member 21, which, however, can also be arranged on the undercarriage 13 according to FIG. 4, the free end of the tension member 22 being fastened to the structure 2 via the articulation 27, the undercarriage 13 is thus moved on the guide rail 11, which The height of the nacelle 10, on the other hand, is changed by means of the drive member 31, which is in drive connection with the nacelle 10 via the tension member 32.

Bei der Ausführungsvariante nach Figur 5 ist das Antriebsglied 31 an der Gondel 10 angebracht und das freie Ende des Zuggliedes 32 ist mittels der Anlenkung 37 an dem Bauwerk 2 befestigt. Die Höhenverstellung der Gondel 10 wird somit mit Hilfe des Antriebsgliedes 31 bewerkstelligt. Zum seitlichen Versetzen des Fahrwerkes 13 auf der Führungsschiene 11 dient wiederum das Antriebsglied 21, dessen zugeordnetes Zugglied 22 mittels der Anlenkung 27' mit dem Fahrwerk 13 verbunden ist.5, the drive member 31 is attached to the nacelle 10 and the free end of the tension member 32 is fastened to the structure 2 by means of the linkage 37. The height adjustment of the nacelle 10 is thus accomplished with the aid of the drive member 31. The drive member 21, whose associated tension member 22 is connected to the undercarriage 13 by means of the linkage 27 ′, is again used for laterally displacing the undercarriage 13 on the guide rail 11.
