Description

Die Erfindung bezieht sich auf einen abgespannten Mast, der an seiner Spitze Sensoren und/oder Antennen trägt. The invention relates to a guyed tower, which carries at its tip sensors and / or antennae.

Hochmaste dieser Art werden häufig eingesetzt, um Nachrich tenverbindungen, insbesondere für militärische Aufgaben zu schalten. High masts of this type are often used to tenverbindungen Nachrich to switch especially for military tasks. Die Zuverlässigkeit solcher Nachrichtenstrecken hängt dabei von der Ausrichtgenauigkeit der an den Masten angebrachten Sensoren bzw. Antennen ab. The reliability of such messages routes depends on The accuracy of identification affixed to the poles sensors or antennas. Da Witterungseinflüs se insbesondere Winde nicht ohne Einfluß auf die Ausrichtge nauigkeit sind, ist es notwendig, die Maste mit genügend ho her Steifigkeit zu versehen oder mittels Seile und Erdankern zu verspannen. Since Witterungseinflüs se particular winch not without influence on the Ausrichtge are accuracy, it is necessary to provide the poles with sufficient stiffness or ho forth to clamp by means of ropes and ground anchors. Maste hinreichender Steifigkeit lassen sich aber nur mit entsprechend dimensionierten Mastelementen auf bauen, was sich dann aber auch durch ein entsprechendes Ge wicht ausdrückt. But masts sufficient rigidity can be only with appropriately sized mast elements to build, but what then weight is also expressed by a corresponding Ge.

Wie aus der DE-PS 9 26 919 hervorgeht, ist es bekannt, Hoch maste mit Seilen abzuspannen und die an der Mastspitze ange ordneten Antennen auszurichten. As is apparent from the DE-PS 9 26 919, it is known, high masts with ropes unclamp and align the antennas is arranged at the mast top. Dazu sind dort die Antennen in Rahmen gehaltert, die mit Steuermotoren und Schneckenge trieben eingestellt werden können. These antennas are there held in frames that exaggerated with control motors and worm can be adjusted. Fehlausrichtungen der An tennen lassen sich daher durch Nachstellungen ausgleichen. therefore let antennas misalignments of An be offset by adjustments.

Der Erfindung liegt daher die Aufgabe zugrunde, einen abge spannten Mast mit einer Vorrichtung zum Stabilisieren von Sensoren und/oder Antennen zu versehen, die es erlaubt, mit einfachen Mitteln die Ausrichtgenauigkeit der Sensoren ein zuhalten. The invention is therefore based on the object to provide a tensioned abge mast with a device for stabilizing sensors and / or antennae which allows the alignment accuracy of the sensors, a hold with simple means.

Diese Aufgabe wird durch die Kennzeichenmerkmale im Anspruch 1 und 8 gelöst. This object is solved by the characterizing features in claim 1 and 8. FIG.

Die erfindungsgemäße Maßnahme hat den Vorteil, daß die Nei gung des Sensorträgers wegen dessen kardanischer Anlenkung unabhängig von der Neigung der Mastspitze ist. The measure according to the invention has the advantage that the Nei's supply of the sensor support regardless of the inclination of the mast top because of its cardanic linkage.

Dies hat zur Folge, daß eine einmal eingestellte Ausrichtung der am Sensorträger ange brachten Sensoren oder Antennen, und zwar durch die paral lele Seilführung, stets aufrechterhalten wird. This has the consequence that an once adjusted orientation of the sensor carrier mounted sensors or antennas, by the paral Lele cable guide is always maintained. Die Maste brauchen daher hinsichtlich ihrer Steifigkeit und Festig keit nicht mehr so stark ausgelegt zu werden, so daß sich hierdurch auch Gewichtseinsparungen und Handhabungsvortei le ergeben. Therefore, the masts need in terms of their rigidity and Festig ness no longer be so strongly designed so that thereby also give weight savings and Handhabungsvortei le. Außerdem haben die auf den Sensorträger wir kenden Windkräfte und das hierdurch entstehende Moment keine Auswirkungen auf den Mast, weil eine kardanische La gerung keine Momente übertragen kann. also have the sensor on the carrier we kenden wind forces and the thereby resulting moment no impact on the mast because a gimbal La delay can not transfer moments. Windkräfte wirken sich daher lediglich als vertikale Zugkräfte auf die Zug elemente aus, so daß sich hierdurch auch Verbesserungen hinsichtlich der Mastdimensionierung ergeben. Therefore, wind forces act merely as a vertical tensile forces to the train of elements, so that thereby also give improvements in the mast dimensions.

Die erfindungsgemäße Vorrichtung ermöglicht es daher auch, Maste in sog. Leichtbauweise vorzugsweise mit Aluminium werkstoffen herzustellen. Therefore, the apparatus according to the invention also makes it possible in so-called poles. lightweight construction materials, preferably with aluminum to produce. Der gegenüber Stahl geringere Elastizitätsmodul von Aluminium mit der sich daraus erge benden Weichheit der Maste kann sich dann nicht so auf die Ausrichtgenauigkeit auswirken. The opposite lower steel Young's modulus of aluminum with which erge from them shall softness of the masts can not then so affect the alignment accuracy is. Daher können mit der erfindungsgemäßen Vorrichtung Antennenmaste vorzugsweise für mobile Einsätze hergestellt werden. Therefore, can be prepared for mobile use with the inventive device preferably Antenna masts.

Die Erfindung wird anhand eines in der Zeichnung darge stellten Ausführungsbeispieles näher erläutert. The invention is further illustrated with reference to a set in the drawing Darge embodiment.

Die Darstellung zeigt das Prinzip eines Teleskopmastes, der an seinem oberen Mastschuß 1′ einen Sensorträger 2 mit zwei daran befestigten Parabolantennen 3, 4 trägt. The figure shows the principle of a telescopic mast, which carries at its upper mast section 1 'has a sensor support 2 with two attached thereto parabolic antennas 3 4. Der Sensorträger 2 ist mit dem oberen Mastschuß 1′ über ein Kardangelenk 5 verbunden, das Bewegungen des Sensorträ gers 2 um die horizontalen Achsen erlaubt. The sensor carrier 2 is connected to the upper mast section 1 'via a universal joint 5, allows the movements of the Sensorträ gers 2 about the horizontal axes. Für Bewegun gen um die vertikale Achse ist das Kardangelenk 5 steif, so daß Torsionskräfte und Querkräfte in den Mast 1 eingelei tet werden. For Bewegun gen about the vertical axis is the universal joint 5 stiff so that torsional forces and shear forces in the mast 1 eingelei be tet. Oberhalb des Kardangelenks 5 sind vier kreuz förmig ausgerichtete horizontale Streben 6 am Sensorträ ger 2 angebracht, von deren Enden Zugseile 7 zum Mastgrund 8 führen. Above the universal joint 5, four cross-shaped aligned horizontal struts 6 are attached to the Sensorträ ger 2, leading from the ends of traction cables 7 to the mast base. 8 Die Zugseile 7 sind mit gleichem Abstand zur Mastachse an den Streben 6 und am Mastgrund 8 befestigt und verlaufen somit parallel zueinander. The lift cords 7 are attached with the same distance to the mast axis on the strut 6 and the mast base 8, and thus parallel to each other. Diese Parallel führung der Zugseile 7 gewährleistet bei Durchbiegungen des Teleskopmastes 1 beispielsweise aufgrund von Windkräf ten, die Ausrichtung der am Sensorträger 2 angebrachten Antennen 3, 4 . This parallel guidance of the tension cables 7 ensured with deflections of the telescopic mast 1, for example due to wind Strengthens th, the orientation of the sensor mounted on the carrier 2 antennas 3 4. Bei einer Auslenkung des Mastes, wie gestrichelt an gedeutet, kann somit keine Veränderung der Neigungen entstehen, während der im Azimut gegebenenfalls auftreten de seitliche Versatz wegen der Keulenbereiche der Antennen 3, 4 oder Sensoren vernachlässigt werden kann. With a deflection of the mast, as shown in phantom at interpreted thus no change in the inclinations may arise during occur in azimuth optionally de lateral offset due to the lobe regions of the antennas 3, 4 or sensors can be neglected. Die gesamte An ordnung kann daher auf ein nicht näher dargestelltes Trans portfahrzeug für mobile Einsatzzwecke aufgebaut werden. can order the whole to therefore transport vehicle on a not-shown Trans for mobile applications are built.

Das Kardangelenk 5 könnte auch durch ein Kugelgelenk er setzt werden, aber ein Kugelgelenk würde Torsions- und Querkräfte nicht abfangen und eine Verdrehung des Sensor trägers 2 zur Folge haben. The universal joint 5 could also be a ball joint, it is but a ball joint would not intercept torsional and lateral forces and a rotation of the sensor carrier 2 also be impaired. Ein Kugelgelenk kann daher nur dann eingesetzt werden, wenn die auftretenden Änderungen im Azimut vernachlässigbar sind. A ball joint can only be used, therefore, when the changes occurring in azimuth are negligible. Die Streben 6 am Sensor träger 2 können an diesem starr, z. The struts 6 on the sensor carrier 2 can in this rigid, z. B. angeschweißt oder auch gelenkig angebracht sein und mittels zur Spitze des Sensoträgers führender Zugelemente verspannt werden. B. welded or be hinged, and are clamped by means of the tip of the leading Sensoträgers tension elements. So wohl in diesen als auch in den Zugelementen 7 ist es zweck mäßig Spannvorrichtungen einzusetzen. So well in these and in the tension elements 7 it is more appropriate to use standard fixtures. Die erfindungsgemäße Vorrichtung bietet darüber hinaus die Möglichkeit, mehrere kardanisch angelenkte Sensorträger übereinander zu setzen bzw. den gesamten Mast aus übereinander kardanisch ange lenkten Sensorträgern aufzubauen. The device also offers the possibility to set several gimbal hinged sensor carrier above the other and build the entire mast above the other gimbal hinged sensor carriers.
