Description

Die Erfindung betrifft einen Teleskopmast mit mehreren, koaxialen und höhenverstellbar ausgebildeten Mastschüssen und jeweils am inneren Mastschuß vorgesehenen Vorrichtungen zum Verriegeln benachbarter Mastschüsse, sowie einer am Boden des äußersten Mastschusses angeordneten Hubeinheit.The invention relates to a telescopic mast with a plurality of coaxial and height-adjustable mast sections and devices provided on the inner mast section for locking adjacent mast sections, and a lifting unit arranged on the bottom of the outermost mast section.

Zum Übertragen von Nachrichten im zivilen und militärischen Bereich werden häufig als Ersatz oder Ergänzung zu festen Bauwerken transportable, ausfahrbare Antennenmaste verwendet. Solche Antennenmaste bestehen meistens aus mehreren ineinander steckenden Mastschüssen, die mit Hilfe unterschiedlicher Antriebe ausfahrbar sind. Zum Ausfahren der Maste werden häufig Seilantriebe eingesetzt, die jedoch störanfällig sind, da das Einfahren nur mit Hilfe des Eigengewichtes erfolgt. Eine solche Antriebsart führt zum Beispiel bei Vereisungen zum völligen Versagen des Einfahrens.Portable, extendable antenna masts are often used to replace messages in the civil and military field as a replacement or supplement to fixed structures. Such antenna masts usually consist of several interlocking mast sections that can be extended using different drives. Rope drives are often used to extend the masts, but they are prone to failure because the retraction only takes place with the help of the dead weight. Such a type of drive leads, for example, to complete failure of retraction in the event of icing.

Hydraulische Antriebseinrichtungen zum Ein-und Ausfahren der Mastschüsse sind ebenfalls störanfällig. Mit Störungen muß besonders dann gerechnet werden, wenn diese die Last der ausgefahrenen Mastschüsse über längere Zeit halten müssen. Bei solchen Antriebseinrichtungen können die Hydraulikdichtungen beim Wiederausfahren schadhaft werden.Hydraulic drive devices for retracting and extending the mast sections are also prone to failure. Disruptions must be expected especially if they have to hold the load of the extended mast shots for a long time. With such drive devices, the hydraulic seals can become defective when they are extended again.

Ein weiterer Nachteil hydraulisch ausfahrbarer Antennenmaste ist dann zu erwarten, wenn die Mastschüsse abgespannt werden müssen. Aufgrund von Temperaturunterschieden ergeben sich Volumenänderungen der Hydraulikölsäule und damit Längenänderungen für die Masthöhe. Dadurch können die Abspannseile schlaff werden oder überspannen.Another disadvantage of hydraulically extendable antenna masts is to be expected if the mast sections have to be anchored. Due to temperature differences, there are changes in the volume of the hydraulic oil column and thus changes in length for the mast height. This can cause the guy ropes to become slack or stretch.

Zur Vermeidung dieser Nachteile ist es bekannt, Verriegelungseinrichtungen von Schuß zu Schuß einzusetzen, die von unten mittels Gestänge oder Seilzüge ver- und/oder entriegelt werden.To avoid these disadvantages, it is known to use locking devices from shot to shot, which are locked and / or unlocked from below by means of linkages or cables.

Verriegelungseinrichtungen für die Mastschüsse gattungsgemäßer Maste sind aus der deutschen Gebrauchsmusterschrift G 85 10 990.8, der deutschen Auslegeschrift 1 252 882, sowie den deutschen Patentschriften P 31 29 661 und 32 14 351 bekannt. Nachteilig bei Verriegelungseinunrichtungen ist, daß diese ohne zusätzliche Maßnahmen bei Vereisungen funktionsunfähig werden, und daß ein ordnungsgemäßes Einrasten von unten durch den Bediener der Einrichtung oft nicht erkennbar ist, was zu Schäden führen kann.Locking devices for the mast shots of generic masts are known from the German utility model G 85 10 990.8, the German designation 1 252 882, and the German patents P 31 29 661 and 32 14 351. Disadvantages of locking devices are that they become inoperable without additional measures in the case of icing, and that a correct engagement from below is often not recognizable by the operator of the device, which can lead to damage.

Die Aufgabe der Erfindung ist es, einen Teleskopmast gemäß dem Oberbegriff des Anspruches 1 so auszubilden, daß die genannten Nachteile vermieden werden.The object of the invention is to design a telescopic mast according to the preamble of claim 1 so that the disadvantages mentioned are avoided.

Die erfindungegemäße Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Hauptanspruches, vorteilhafte Ausgestaltungen und Weiterbildungen sind den Unteransprüchen zu entnehmen.The achievement of this task according to the invention results from the features of the main claim, advantageous refinements and developments can be found in the subclaims.

Der erfindungsgemäße Verriegelungsmechanismus wird mit Hilfe einer einstufigen Hubeinheit in den Mastschüssen durch Drehen derselben betätigt. Während des Drehenvorgangs der Hubeinheit werden Riegel zwischen dem zu fixierenden Mastschuß und dem bereits feststehenden Mastschuß eingeschoben. Nachdem der Mastschuß so verriegelt wurde, steht die Hubeinheit für den Aushub eines weiteren Mastschusses und dessen Verriegelung zur Verfügung. Die Entriegelung und das Einfahren der Mastschüsse erfolgt in entgegengesetzter Reihenfolge mit aktiver Krafteinwirkung durch die Hubeinheit.The locking mechanism according to the invention is actuated with the help of a single-stage lifting unit in the mast sections by rotating the same. During the turning process of the lifting unit, bolts are inserted between the mast section to be fixed and the already fixed mast section. After the mast section has been locked in this way, the lifting unit is available for the excavation of another mast section and its locking. The mast sections are unlocked and retracted in the opposite order with active force from the lifting unit.

Ein Ausführungsbeispiel der Erfindung wird mit Hilfe der Zeichnung erläutert. Es zeigen:

  • Fig. 1 einen Längsschnitt durch eine Hubeinheit in einem eingefahrenen und verriegelten vierschüssigen Mast,
  • Fig. 2 einen Längsschnitt durch die Hubeinheit mit ausgefahrenen und oben verriegelten innersten Mastschuß wobei sich die Hubeinheit abwärts bewegt,
  • Fig. 3 einen Querschnitt AA von Figur 1 in unterer Verriegelungsposition,
  • Fig. 4 einen Querschnitt AA von Figur 1 in unterer Entriegelungsposition,
  • Fig. 5 einen Querschnitt AA von Figur 1 in oberer Verriegelungsposition,
  • Fig. 6 einen Querschnitt AA von Figur 1 in oberer Verriegelungsposition, jedoch ohne Einzelteile.
An embodiment of the invention is explained with the help of the drawing. Show it:
  • 1 is a longitudinal section through a lifting unit in a retracted and locked four-shot mast,
  • 2 shows a longitudinal section through the lifting unit with the innermost mast section extended and locked at the top, the lifting unit moving downwards,
  • 3 shows a cross section AA from FIG. 1 in the lower locking position,
  • 4 shows a cross section AA from FIG. 1 in the lower unlocking position,
  • 5 shows a cross section AA of Figure 1 in the upper locking position,
  • Fig. 6 shows a cross section AA of Figure 1 in the upper locking position, but without individual parts.

Der in Figur dargestellte Mast wird durch vier Mastschüsse 1,2, 3,4 gebildet, innerhalb derer eine einstufige Hubeinheit 7 das Ein- und Ausfahren sowie das Ver- und Entriegeln der Mastschüsse 1,2,3,4 mit Hilfe eines Hebels 11 gestattet. Im eingefahrenen und verriegeltem Zustand sind die einzelnen Mastschüsse mit Hilfe von Riegeln 5 untereinander verbunden und wie in Figur 3 dargestellt positioniert. Dabei sind die Knaggen 6 der Hubeinheit 7 eingetaucht zwischen .Mitnehmerblechen 8, die mit Aussparungen 9 versehen sind (Figur 3, Figur 6).The mast shown in the figure is formed by four mast sections 1, 2, 3, 4, within which a single-stage lifting unit 7 permits the retraction and extension as well as the locking and unlocking of the mast sections 1, 2, 3, 4 by means of a lever 11 . In the retracted and locked state, the individual mast sections are connected to one another with the aid of bolts 5 and positioned as shown in FIG. 3. The lugs 6 of the lifting unit 7 are immersed between the driver plates 8, which are provided with cutouts 9 (FIG. 3, FIG. 6).

Zum Ausfahren des Mastes wird durch Drehen des Hebels 11 um die Längsachse der Hubeinheit 7 der anzuhebende Mastschuß 1 entriegelt. Dies geschieht dadurch, daß die Knaggen 6 der Hubeinheit 7 ein Bauteil 10 um einen bestimmten Winkel im Uhrzeigersinn verdrehen. Die Riegel 5 sind mit dem Bauteil 10 verzahnt angeordnet, so daß die Drehung der Hubeinheit 7 ein Entriegeln des anzuhebenden Mastschusses bewirkt (Figur 3, Figur 4). In der in Figur 4 dargestellten Entriegelungsposition befinden sich die Knaggen 6 zwischen den Mitnehmerblechen 8 und der Mastschuß 1 ist formschlüssig mit der Hubeinheit 7 verbunden. Durch Aktivieren der Hubeinheit 7 bewegt sich der Mastschuß 1 aufwärts. Wenn der Mastschuß 1 wenige Millimeter angehoben wurde, ist ein Austauchen der Knaggen 6 aus den Mitnehmerblechen 8 nicht mehr möglich, da die Riegel 5 gemäß Figur 4 bei einem erneuten Verdrehen der Hubeinheit 7 durch die Innenwand des Mastschusses 2 blockiert werden.To extend the mast, the mast section 1 to be lifted is unlocked by rotating the lever 11 about the longitudinal axis of the lifting unit 7. This is done by the knobs 6 of the lifting unit 7 rotating a component 10 clockwise by a certain angle. The bolts 5 are arranged in a toothed manner with the component 10, so that the rotation of the lifting unit 7 brings about an unlocking of the mast section to be lifted (FIG. 3, FIG. 4). In the unlocking position shown in FIG. 4, the lugs 6 are located between the driving plates 8 and the mast section 1 is positively connected to the lifting unit 7. By activating the lifting unit 7, the mast section 1 moves upwards. If the mast section 1 has been raised a few millimeters, it is no longer possible for the lugs 6 to emerge from the driving plates 8, since the bars 5 according to FIG. 4 are blocked by the inner wall of the mast section 2 when the lifting unit 7 is rotated again.

Nachdem der Mastschuß 1 in die obere Endlage gehoben wurde, werden durch erneutes Drehen des Hebels 11 im Uhrzeigersinn Mastschuß 1 und Mastschuß 2 mit Hilfe der Riegel 5 miteinander verbunden, Figur 5 zeigt die verriegelten Mastschüsse 1 und 2, wobei die Knaggen 6 sich in den Aussparungen 12 des Bauteils 10 (Figur 6) befinden und somit abwärts bewegt werden können. Durch Bewegen von Hebel 11 entgegen dem Uhrzeigersinn bis zu einem Anschlag, wird die Hubeinheit 7 mit den Knaggen 6 in die Einfahrposition für den nächsten anzuhebenden Mastschuß gebracht. In dieser Stellung sind die Knaggen 6 über den Aussparungen 9 der Mitnehmerbleche 8 positioniert und der Entriegelungs-, Hebe- und Verriegelungsvorgang kann wie beschrieben von neuem für den nächsten Mastschuß ablaufen (Figur 6, Figur 3).After the mast section 1 has been raised to the upper end position, the mast section 1 and the mast section 2 are connected to one another by means of the latch 5 by turning the lever 11 clockwise again; FIG Cutouts 12 of component 10 (FIG. 6) are located and can thus be moved downwards. By moving lever 11 counterclockwise until it stops, the lifting unit 7 with the lugs 6 is brought into the retracted position for the next mast section to be lifted. In this position, the lugs 6 are positioned above the recesses 9 of the driving plates 8 and the unlocking, lifting and locking process can take place again as described for the next mast section (FIG. 6, FIG. 3).

Das Einfahren der Mastschüsse geschieht in entgegengesetzter Reihenfolge wie beim Ausfahren, wobei der zuerst ausgefahrene Mastschuß 1 als letzter eingezogen wird. Erfindungsgemäß wird dabei durch die formschlüssige Verbindung der Hubeinheit 7 mit dem jeweiligen Mastschuß ein kraftbewegtes Einfahren möglich. Dadurch lassen sich auch in vereistem Zustand die Mastschüsse zuverlässig Einfahren.The mast sections are retracted in the opposite order to when the mast sections 1 are extended, with the first mast section 1 being drawn in last. According to the invention, the positive connection of the lifting unit 7 with the respective mast section enables force-moving retraction. This means that the mast sections can be reliably retracted, even in the icy condition.

Der Einsatz der erfindungsgemäßen Verriegelungseinrichtung kann bei unterschiedlichen Masttypen erfolgen, wie zum Beispiel bei Vollwandmaste und Gittermaste, die rund, dreieckig, viereckig oder vieleckig sind. Als Hubeinheiten können beispielsweise Spindelantriebe, Hydrauliksysteme und geschlossene Seilsysteme Verwendung finden.The locking device according to the invention can be used with different types of masts, for example with solid wall masts and lattice masts which are round, triangular, quadrangular or polygonal. For example, spindle drives, hydraulic systems and closed cable systems can be used as lifting units.

Ein weiterer Vorteil der Erfindung ist, daß stets eine kostengünstige einstufige Hubeinheit zur Anwendung gelangen kann. Durch das Drehen der Hubeinheit wird der zu hebende Mastschuß erfaßt, zugleich entriegelt und sodann angehoben. Sobald der Mastschuß in der oberen Endlage angekommen ist, wird durch ein weiteres Drehen der Hubeinheit der obere Mastschuß mit dem feststehenden verriegelt und anschließend zum Absenken freigegeben. Durch diese einfache Handhabung ist eine Fehlbedienung mit Schadensfolge nicht möglich.Another advantage of the invention is that an inexpensive single-stage lifting unit can always be used. By turning the lifting unit, the mast section to be lifted is gripped, unlocked at the same time and then raised. As soon as the mast section has reached the upper end position, the upper mast section is locked with the fixed one by turning the lifting unit again and then released for lowering. This simple handling means that incorrect operation with consequential damage is not possible.
