KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine neuartige Sicherung der Rohrstöße von Teleskoprohrmasten gegen Durchbiegung oder Ausknickung an den ineinander stecken bleibenden Teilen.The subject of the invention is a novel securing of the pipe joints of telescopic pipe masts against bending or buckling of the parts that get stuck together.
Die Vorrichtung besteht darin, daß die Innenrohre keilförmig nach oben verlaufende, die Außenrohre dagegen in gleichem Sinne keilförmig nach unten verlaufende Verstärkungen erhalten, welche sich beim Ausziehen der Rohre ineinander schieben.The device consists in that the inner tubes wedge-shaped upwards, the outer tubes, on the other hand, have reinforcements running downwards in a wedge shape in the same sense which slide into each other when the tubes are pulled out.
In der Zeichnung ist in Fig. 1 eine Seitenansicht, in Fig. 2 eine Aufsicht dieser Anordnung dargestellt. Als Beispiel ist hier ein Vierkantmast gewählt worden, es können aber selbstverständlich auch Maste anderer, beliebiger Querschnitte so ausgebildet werden.In the drawing, FIG. 1 shows a side view and FIG. 2 shows a plan view of this arrangement shown. A square mast has been chosen as an example, but it can Of course, masts of other, arbitrary cross-sections can also be designed in this way.
Das Außenrohr α trägt Innenverstärkungen d, welche nach unten keilförmig zulaufen; das Innenrohr b trägt Auflagen c, welche in gleichem Sinne keilförmig nach oben verlaufen.The outer tube α carries inner reinforcements d, which taper downwards in a wedge shape; the inner tube b carries supports c, which run in the same direction in a wedge shape upwards.
Wenn die Maste ausgezogen sind, so stoßen die Anlaufflächen der Verstärkungen an den Rohrstößen gegeneinander. Da z. B. beim Vierkantmast vier Verstärkungen vorhanden sind, so werden die Führungen je zweier gegenüberliegender Seiten nur ein Ausweichen des Mastes in der senkrecht auf diesen stehenden Richtung gestatten. Dieses Ausweichen ist aber unmöglich, da die Kanten der Verstärkungen der beiden andern Seiten dies nicht gestatten. Es ist somit durch die Berührung der Keilflächen ein starres Sicherheitsmoment gegeben.When the masts are extended, the contact surfaces of the reinforcements hit the Pipe butt against each other. Since z. B. There are four reinforcements in the square mast are, the guides are only an evasion of the two opposite sides Permit the mast in the direction perpendicular to it. This dodging is but impossible, since the edges of the reinforcements on the other two sides do not allow. It is therefore a rigid safety factor due to the contact with the wedge surfaces given.
