Abstract
Description
Die Erfindung betrifft ein Verfahren zur Montage von Rohr-Gitter- Masten mit dem Hubschrauber, ohne daß sich während des Einfliegens Hilfs- oder Montagekräfte an den Aufnahmepunkten des Unterteiles (1) und damit im gefährdeten Bereich unterhalb einer schwebenden Last befinden.The invention relates to a method for assembling pipe-lattice masts with the helicopter, without auxiliary or assembly forces being at the pick-up points of the lower part ( 1 ) and thus in the endangered area below a suspended load during the flying in.
Die Aufgabe der Erfindung besteht daher darin, daß die Verbindungen der Rohrsegmente (1) und (2) so gestaltet werden, daß ein vertikales Zusammenfügen von geneigten Profilen, die sich durch die Bauart eines jeden Mastes ergeben, gewährleistet wird (Fall-Linie, Fig. 3), ohne daß aufwendige Hilfskonstruktionen benötigt werden.The object of the invention is therefore that the connections of the pipe segments ( 1 ) and ( 2 ) are designed so that a vertical assembly of inclined profiles, which result from the design of each mast, is guaranteed (fall line, Fig . 3) are required without the need for expensive auxiliary constructions.
Dieses wird durch die Formgebung der beiden Paßstücke "Mutter" (8) und "Vater" (7) erreicht, die konisch ausgeführt die Angleichung an die verschiedensten Neigungswinkel ermöglichen. Je nach gewünschter Zug-/Belastungsfähigkeit läßt sich auch eine "sparsame" Materialausführung des Zapfens (7) wählen, wobei das Gegenstück (8) nicht aus Vollmaterial, sondern als Rohr ausgelegt wird. Am Prinzip ändert sich dadurch nichts.This is achieved by the shape of the two adapters "mother" ( 8 ) and "father" ( 7 ), which are conical and allow adjustment to the most varied angles of inclination. Depending on the desired tensile / load capacity, an "economical" material version of the pin ( 7 ) can also be selected, the counterpart ( 8 ) not being made of solid material, but of a tube. This does not change the principle.
Die Verriegelung der Verschlußstücke kann wahlweise über eine koaxial eingebaute Konus-Halterung (5), die über eine vorgespannte Feder bei Auftreffen des Zapfens (7) auf dem Sensor (6) in den Nut (9) rotiert und je nach eingestellter Federkraft die beiden Verschlußstücke (7) und (8) noch zusätzlich zusammenzieht. Ein nach außen geführter Inbus kann ein nachträgliches Spannen ebenfalls ermöglichen. Auch dadurch bleibt die äußere Oberfläche des Rohrprofils ohne Hindernisse, die Feuchtigkeit aufnehmen und Korrosion bilden lassen. Entsprechende Markierungen lassen die genaue Rotationsstellung der Konushalterung (5) von außen jederzeit kontrolliert.The locking pieces can optionally be locked via a coaxially installed cone holder ( 5 ), which rotates via a pre-tensioned spring when the pin ( 7 ) hits the sensor ( 6 ) in the groove ( 9 ) and, depending on the spring force set, the two locking pieces ( 7 ) and ( 8 ) additionally pulls together. An external hex can also enable subsequent tensioning. This also leaves the outer surface of the tubular profile free from obstacles that absorb moisture and cause corrosion. Appropriate markings allow the exact rotational position of the cone holder ( 5 ) to be checked from the outside at all times.
Anstelle der Konushalterung (5) kann auch eine einfachere Halterung in Form eines "Schnapp-Riegels" (11) eine Fixierung der beiden Verschlußstücke (7) und (8) erreichen, der in einer Aussparung (12) des Verschlußstückes (8) mit einer Feder (13) gespannt ruht.Instead of the cone holder ( 5 ), a simpler holder in the form of a "snap-lock" ( 11 ) can fix the two closure pieces ( 7 ) and ( 8 ) in a recess ( 12 ) of the closure piece ( 8 ) with a Spring ( 13 ) rests under tension.
Beim Einführen des Verschlußstückes (7) wird über die Fläche (3) des Verschlußstückes der Keilbolzen (11) in die Führung (12) gedrückt und die Feder (13) gespannt. Setzt das Verschlußstück (7) im Unterteil (8) auf, so drückt die vorgespannte Feder (13) den Keilbolzen (11) in die Aussparung (14), und eine kraftschlüssige Verbindung ist hergestellt. Über einen hier nicht gezeigten Stift zeigt sich außen, ob die Feder gespannt oder entlastet ist und somit die genaue Position des Keilbolzens (11) innerhalb der Führung (12) bzw. der Aussparung (14).When inserting the closure piece ( 7 ), the wedge bolt ( 11 ) is pressed into the guide ( 12 ) over the surface ( 3 ) of the closure piece and the spring ( 13 ) is tensioned. If the closure piece ( 7 ) is placed in the lower part ( 8 ), the prestressed spring ( 13 ) presses the wedge bolt ( 11 ) into the recess ( 14 ), and a force-fit connection is established. A pin (not shown here) shows on the outside whether the spring is tensioned or relieved and thus the exact position of the wedge pin ( 11 ) within the guide ( 12 ) or the recess ( 14 ).
Anstelle der Feder alleine kann eine pyrotechnische Treibladung (15) verwendet werden, die den Keilbolzen (11) in die Nut (14) treibt, sobald ein Sensor (17) die Zündung auslöst. Eine Riegelfalle (16) verhindert ein Zurückrutschen des Keilbolzens (11).Instead of the spring alone, a pyrotechnic propellant charge ( 15 ) can be used, which drives the wedge pin ( 11 ) into the groove ( 14 ) as soon as a sensor ( 17 ) triggers the ignition. A bolt latch ( 16 ) prevents the wedge bolt ( 11 ) from sliding back.
Bei einem sogenannten gekapselten System wird das Funktionieren der Treibladung (15) über die Injektionsbohrung (4) kontrolliert, da sich dann dort der Pulverschmauch zeigt.In a so-called encapsulated system, the functioning of the propellant charge ( 15 ) is checked via the injection hole ( 4 ), since the powder smoke is then shown there.
Die endgültige und kraftschlüssige Verbindung der beiden Verschlußstücke (7) und (8) wird dadurch erhöht, indem über eine Bohrung (4) ein Metallkleber injiziert wird, die die Flächen dauerhaft verklebt. Zum Erreichen einer besseren Haftung werden die Oberflächen der zu klebenden Teile (3) entsprechend vorbehandelt. Die beiden Verschlußstücke selbst können ebenfalls in die Rohre eingeklebt werden. Es zeigtThe final and non-positive connection of the two closure pieces ( 7 ) and ( 8 ) is increased by injecting a metal adhesive through a hole ( 4 ) that permanently glues the surfaces. To achieve better adhesion, the surfaces of the parts ( 3 ) to be glued are pretreated accordingly. The two closure pieces themselves can also be glued into the tubes. It shows
