Description

Die vorliegende Erfindung betrifft eine Einrichtung zur Aufnahme eines teleskopartig längenveränderlichen Mastes auf einem mobilen Träger, mit Mitteln zur Verschwenkung des Mastes wahlweise in eine im wesentlichen horizontale Transportstellung mit eingefahrenen , oder in eine vertikale Arbeitsstellung mit ausgefahrenen Teleskopelementen, in der der Mast bzw. der Träger mittels Abstützungen gegenüber der Bodenfläche abgestützt ist.The present invention relates to a device for receiving a telescopically variable mast on a mobile carrier, with means for pivoting the mast either in a substantially horizontal transport position with retracted, or in a vertical working position with extended telescopic elements, in which the mast or the carrier is supported against the floor surface by means of supports.

Derartige, teleskopartig längenveränderliche Masten dienen beispielsweise als Träger von Antennen für den Funkbetrieb, für Fernsehübertragungen oder andere Sende- oder Empfangszwecke oder auch als Relaisstationen. Mobile Betriebsanlagen der genannten Art müssen in kürzester Zeit und aus wirtschaftlichen Gründen mit geringstmöglichem, gerätetechnischen Aufwand bei gleichzeitig geringstmöglichem personellen Einsatz an unterschiedlichen Orten aufstellbar bzw. abbaubar ausgebildet sein.
Von bisherigen Ausbildungen ist bekannt, Masten der genannten Art mittels ineinander oder aneinander verschiebbarer Elemente vertikal auf eine vorgegebene Höhe auszufahren, in dieser Stellung zu verspannen und mittels ausfahrbarer Fußteile bzw. Stützausleger gegenüber dem Erdboden abzustützen. Für den Transport werden die Teleskopelemente eingefahren und die Masten in eine horizontale Transportstellung verschwenkt.
Es ist eine solche Einrichtung bekannt, bei der ein teleskopartig längenveränderlicher Mast an einem Tragarm schwenkbar gelagert ist und mittels einer Verstelleinrichtung in eine vertikale Arbeitsstellung oder eine horizontale Transportstellung mit in Einfahrstellung gebrachten Teleskopelementen verstellbar ist.Such telescopically variable masts serve, for example, as carriers for antennas for radio operation, for television transmissions or other transmission or reception purposes or as relay stations. Mobile operating systems of the type mentioned must be designed to be capable of being set up or dismantled in different places in the shortest possible time and for economic reasons with the least possible expenditure on equipment and at the same time the lowest possible use of personnel.
From previous training is known, masts of the type mentioned vertically to one another by means of elements which can be moved into or against one another Extend height, brace in this position and support against the ground by means of extendable foot sections or outrigger. For transport, the telescopic elements are retracted and the masts swiveled into a horizontal transport position.
Such a device is known in which a telescopically variable-length mast is pivotally mounted on a support arm and is adjustable by means of an adjusting device into a vertical working position or a horizontal transport position with telescopic elements brought into the retracted position.

Bei der bekannten Einrichtung bestehen jedoch eine Reihe Schwierigkeiten, die sich aus der zur Aufnahme des Mastes dienenden Fahrzeugkonstruktion und der Ausbildung der Aufnahmeeinrichtung für den Mast ergeben, wobei einerseits die Aufstellung bzw. der Transport eines solchen längenveränderlichen Teleskopmastes in die Arbeitsstellung bzw. in die Transportstellung Nachteile, insbesondere im Hinblick auf die Schwerpunktslage mit sich bringt.In the known device, however, there are a number of difficulties which arise from the vehicle construction used to receive the mast and the design of the receiving device for the mast, with on the one hand the installation or transport of such a variable-length telescopic mast into the working position or into the transport position Disadvantages, especially with regard to the focus.

Aufgabe der vorliegenden Erfindung ist es daher, die der bekannten Ausbildung anhaftenden Mängel zu beseitigen und eine Einrichtung zu schaffen, die einen gerätetechnisch vereinfachten Aufbau, eine verbesserte Wirkungsweise hinsichtlich der Erzielung eines rascheren Auf- bzw. Abbaues der Mastanlage, bei bestmöglicher Stabilität der Mastanlage in bezug auf die Schwerpunktlage, sowohl in der Mastarbeitsstellung als auch der Masttransportstellung.The object of the present invention is therefore to eliminate the deficiencies inherent in the known design and to provide a device which has a device structure which is simplified in terms of equipment, an improved mode of operation with regard to achieving a faster assembly and disassembly of the mast system, with the best possible stability of the mast system in in relation to the center of gravity, both in the mast work position and the mast transport position.

Die gestellte Aufgabe ist erfindungsgemäß gelöst mit einer besonderen Ausbildung der Aufnahme der Mastanlage auf einem mobilen Träger und der zugehörigen Verstelleinrichtung nach den Merkmalen des Patentanspruches 1 und in weiterer, vorteilhafter Ausgestaltung des Haupterfindungsgedankens nach den Merkmalen der dem Anspruch 1 folgender Ansprüche.The object is achieved according to the invention with a special design for receiving the mast system on a mobile carrier and Associated adjustment device according to the features of claim 1 and in a further, advantageous embodiment of the main inventive concept according to the features of the claims following claim 1.

Mittels einer gemäß der Erfindung ausgebildeten Einrichtung wird erreicht, daß die Schwerpunktlage der Mastanlage, sowohl in Arbeitsstellung als auch in ihrer Transportstellung sich stets im Schwerpunkt des Fahrzeuges befindet, wodurch die Ausladung der für die Aufstellungsstabilität erforderlichen aus- bzw. einfahrbaren, auf der Bodenfläche auf liegenden Stützen nur äußerst gering gehalten werden kann. Die Stützen lassen sich bei einer solchen Ausbildung äußerst günstig am Trägerrahmen des Trägerfahrzeuges für den Transport unterbringen.
Die Ausbildung erlaubt ferner, daß das Trägerfahrzeug selbst als Mastgegengewicht herangezogen wird und damit die Stützenausladung, insbesondere bei nur eingeschränkt zur Verfügung stehender Aufstellfläche unter Beibehaltung der Aufstellsicherheit, gering gehalten werden kann.
Durch die besondere Ausbildung des Trägers des Mastschwenklagers bleibt die günstige Schwerpunktlage der Mastanlage auch über den gesamten Verstellweg bei der Verstellung zum Aufrichten bzw. Einfahren des Mastes erhalten.
Außerdem wird mittels der besonderen Ausbildung der Mastschwenklagerung gemeinsam mit der Ausbildung des Traggestells bzw. des Fahrzeugrahmens bewirkt, daß einerseits die Schwerpunktlage des Mastes bzw. der Gesamtanlage für den Transport in äußerst geringem Abstand über der Fahrbahn liegt und andererseits beim Einschwenken des Mastes in die Arbeitsstellung eine Verlagerung des Mastes bzw. seiner Schwenklagerung in vertikaler Richtung mit einem entsprechenden Gewinn an Aufstellungshöhe gegenüber herkömmlichen Ausbildungen erzielt .
Die erfindungsgemäße Ausbildung erlaubt einen Aufbau der Mastanlage auf jedem serienmäßig ausgebildeten Fahrzeugrahmen bzw. Lastaufnahmeteil, ohne jeweils eine kostspielige Anpassung vornehmen zu müssen. Dabei können Zugfahrzeuge selbst, ebenso wie Zugfahrzeuganhänger, in Einachs- oder Mehrachsausführung verwendet werden.By means of a device designed according to the invention it is achieved that the center of gravity of the mast system, both in the working position and in its transport position, is always in the center of gravity of the vehicle, as a result of which the unloading of the extendable and retractable elements required for installation stability is on the floor surface horizontal supports can be kept extremely low. With such a design, the supports can be accommodated extremely cheaply on the carrier frame of the carrier vehicle for transport.
The design also allows the carrier vehicle itself to be used as a mast counterweight and thus the outreach of the supports, in particular if the installation area is only available to a limited extent, while maintaining the installation safety, can be kept low.
Due to the special design of the mast of the mast swivel bearing, the favorable center of gravity of the mast system is also maintained over the entire adjustment path when adjusting for raising or retracting the mast.
In addition, by means of the special design of the mast swivel mounting together with the design of the support frame or the vehicle frame, on the one hand the center of gravity of the mast or the entire system for transport is at an extremely short distance above the road and on the other hand when the mast is swung into the working position a displacement of the mast or its swivel mounting in the vertical direction with a corresponding gain in installation height compared to conventional Training achieved.
The design according to the invention allows the mast system to be set up on any standard vehicle frame or load-bearing part, without having to make any expensive adjustments. Towing vehicles themselves, like towing vehicle trailers, can be used in single-axle or multi-axle versions.

The mast swivel bearing 3 is formed from two coaxial bearing axes 20 on the mast carrier 10 of the element carrier 12 and corresponding bearing bores 21 in the bearing bridge 18 .
For swing mast mounting 3 also serve as swing arms 22 which articulate on the mast 1 via its bearing axles 20 on both sides of the mast 1 to move freely. The rockers 22 serve, which will be explained in more detail later, for parallel pivoting of the bearing axes 20 of the mast pivot bearing 3 on a circular path section from the mast working position into a transport position and vice versa.

Für die Aufnahme des Mastes 1 in Transportstellung ist eine am Traggestell 2 feste Lagergabel 32 mit ihren Gabelteilen 32′ vorgesehen. An den Gabelteilen lagern sich frei drehbar Führungsrollen 31, die mit der gegen die horizontale geneigt verlaufenden Führungsfläche 30′ von Führungsschienen 30 zusammenwirken. Die Schienen 30 sind zu beiden Seiten der Mastlängsmittelebene mit dem Mast 1 bzw. dem Elemententräger 12 des Mastes 1 fest verbunden.For the reception of the mast 1 in the transport position, a fixed bearing fork 32 with its fork parts 32 'is provided on the support frame 2 . On the fork parts are freely rotatable guide rollers 31 , which cooperate with the horizontal inclined guide surface 30 ' of guide rails 30 . The rails 30 are firmly connected to the mast 1 or the element carrier 12 of the mast 1 on both sides of the central longitudinal plane of the mast.

Zur Verschwenkung des Mastes 1 um seine Lagerung 3 ist ferner ein Schwenkantrieb 6, enthaltend einen Stellmotor 50 und ein Verstellspindel-Muttergetriebe 51, vorgesehen. Die Verstellspindel greift über ein Gelenk 52 im Bereich des unteren Mastabschnittes am Elemententräger 12 bzw. am Mastträger 10 frei schwenkbar an. Mit 53 ist ferner noch eine Schwenklagerung bezeichnet, mittels der sich der Schwenkantrieb 6 gelenkig am Traggestell 2 abstützt.In order to pivot the mast 1 about its mounting 3 , a swivel drive 6 containing an actuator 50 and an adjusting spindle nut gear 51 is also provided. The adjusting spindle engages freely via a joint 52 in the area of the lower mast section on the element carrier 12 or on the mast carrier 10 . 53 also designates a pivot bearing by means of which the pivot drive 6 is supported in an articulated manner on the support frame 2 .

In seiner Transportstellung, dargestellt mit gestrichelten Linien, nimmt der Mast 1, bezogen auf seine Längsachse L, eine horizontale Lage auf seinem Traggestellt 2 ein. Dabei sind die Teleskopelemente 11 in den Elemententräger 12 eingefahren.
Der Schwerpunkt S der Mastanlage liegt dabei in maximal geringem Abstand zur Bodenfläche B auf der Längsachse L der Mastanlage über der Radachse 40 des Fahrzeuges 4. The operation of the mast system described is as follows:
The drawing shows the vertical mast swivel position showing the working position of the mast system with dash-dotted lines, the horizontal transport position with dashed lines and the starting pivot position for erecting or pivoting the mast system into the horizontal transport position with solid lines.
In its transport position, shown with dashed lines, the mast 1 assumes a horizontal position on its support frame 2 with respect to its longitudinal axis L. The telescoping members are retracted into the element carrier 12. 11
The center of gravity S of the mast system lies at a maximum distance from the floor surface B on the longitudinal axis L of the mast system above the wheel axis 40 of the vehicle 4.

In der mit ausgezogenen Linien dargestellten Mastlage befindet sich der Mast 1 parallel zur horizontalen Transportlage in maximal angehobener Stellung der Mastschwenklagerung 3.
Die Verstellbewegung erfolgt mittels der Lagerschwingen 22 um die Gelenke 23 bzw. 24, wobei sich die Lagerachsen 20 am Mastträger 10 auf einer Kreisbahn um die Gelenke 23 bzw. 24 am Traggestell 2, geführt von den Lagerschwingen 22, bewegen.
Bei dieser Bewegung findet damit, wie bereits beschrieben, gleichzeitig ein Anheben des Mastes 1 mittels seiner Lagerung 3 und eine Verlagerung des Mastes 1 in horizontaler Richtung statt, und zwar so, daß in der Ausgangsstellung zur Aufrichtung des Mastes 1 in die Vertikale der Schwerpunkt S ebenfalls auf der Längsachse L des Mastes 1 vertikal über der Radachse 40 des Fahrzeuges 4 zu liegen kommt.In the mast position shown with solid lines, the mast 1 is parallel to the horizontal transport position in the maximally raised position of the mast pivot bearing 3 .
The adjustment movement takes place by means of the bearing rockers 22 around the joints 23 and 24 , the bearing axes 20 on the mast support 10 moving in a circular path around the joints 23 and 24 on the support frame 2 , guided by the bearing rockers 22 .
During this movement, as already described, the mast 1 is simultaneously lifted by means of its mounting 3 and the mast 1 is displaced in the horizontal direction, in such a way that in the starting position for the erection of the mast 1 into the vertical the center of gravity S likewise comes to lie vertically above the wheel axis 40 of the vehicle 4 on the longitudinal axis L of the mast 1 .

Bei der in horizontaler Richtung verlaufenden Mastbewegung wird der Mast 1 über die Lagergabel 32 mittels der Führungsrollen 31 und der Führungsschienen 30 mit ihren geneigten Führungsflächen 30′ in seiner Parallelverschiebung in Richtung der Fahrzeuglängsachse unterstützt.In the horizontal movement of the mast movement, the mast 1 is supported via the bearing fork 32 by means of the guide rollers 31 and the guide rails 30 with their inclined guide surfaces 30 ' in its parallel displacement in the direction of the longitudinal axis of the vehicle.

Infolge der Schwenkbewegung der Lagerschwingen 22 werden die Lagerachsen 20 mit ihren Abflachungen 26 in eine Eingriffslage in Bezug auf die Schlitze 27 in den Bohrungen 21 des Mastträgers 10 gebracht, so daß die Lagerachsen 20 in die Lagerbohrungen 21 der am Traggestell 2 festen Lagerbrücke 18 in Eingriff gelangen.
Der Mast 1 schwenkt nach dem Einrasten der Lagerachsen 20 in die Lagerbohrungen 21 bzw. die Schlitze 27 am Mastträger 10 ein. Bei einer Verschwenkung des Mastes 1 um die Lagerachsen 20 verriegeln sich diesedurch die Drehbewegung selbsttätig, sodaß nunmehr der Mast 1 in sämtlichen Richtungen in den in den Lagerbohrungen 21 fixiert ist.As a result of the pivoting movement of the bearing rockers 22 , the bearing axles 20 are brought with their flattened portions 26 into an engagement position with respect to the slots 27 in the bores 21 of the mast support 10 , so that the bearing axles 20 engage in the bearing bores 21 of the bearing bracket 18 fixed on the support frame 2 reach.
After the bearing axles 20 have engaged, the mast 1 pivots into the bearing bores 21 or the slots 27 on the mast support 10 . When the mast 1 is pivoted about the bearing axes 20, they lock themselves automatically due to the rotary movement, so that the mast 1 is now fixed in all directions in the bearing bores 21 .

Mittels des Stellmotors 50 und die über ein Untersetzungsgetriebe und ein Mutterteil verstellbare Verstellspindel 51 wird über den gelenkigen Antrieb 52 der Mast 1 um seine Lagerachsen 20 in den Lagerbohrungen 21 im Brückenteil 18 bzw. am Mastträger 10 in seine vertikale Arbeitsstellung geschwenkt. In dieser Grundstellung des Mastes 1 werden über den Stellmotor 14 und das Getriebe 15 die Teleskopelemente 11 in ihre Ausfahrstellung gebracht .By means of the servomotor 50 and the adjusting spindle 51 , which is adjustable via a reduction gear and a nut part, the mast 1 is pivoted about its bearing axes 20 in the bearing bores 21 in the bridge part 18 or on the mast carrier 10 into its vertical working position via the articulated drive 52 . In this basic position of the mast 1 , the telescopic elements 11 are brought into their extended position via the servomotor 14 and the gear 15 .

Der im Ausführungsbeispiel beschriebene Teleskopmast dient zur Aufnahme von Elementen zur Nachrichtenübermittlung oder dergleichen. Das gezeigte Prinzip ist jedoch auch für andere Aufgabenzwecke, z.B. bei längenveränderlichen Armen für die Aufnahme von Lasten , Geräten oder dergleichen einsetzbar.The telescopic mast described in the exemplary embodiment serves to accommodate elements for transmitting messages or the like. However, the principle shown is also for other task purposes, for example with variable length Arms can be used to hold loads, equipment or the like.
