Description
Beschreibungs Teleskopausleger mit Seilbetätigung, Schräganfhängung der Seilrollen im Teleskopausleger.Description telescopic boom with rope actuation, inclined attachment the pulleys in the telescopic boom.
Die Erfindung betrifft einen Kranausleger der in Jeder Lage atufenlos ein-und auszufahren ist.The invention relates to a crane boom which does not have any steps in any position is to drive in and out.
Bei diesem Teleskopausleger ist der Hanptzweck, den Kran in verschiedencn Auslegerlängen in kürzester Zeit einsatzbereit zu haben.The purpose of this telescopic boom is to move the crane in different ways To have boom lengths ready for use in the shortest possible time.
Sämtliohe bisher gebauten Teleskopausleger erreichen das Aus-und einziehen mit hydraulischen Zyliudern.All telescopic booms built so far can be extended and retracted with hydraulic cylinders.
An diesen hydrauliachen Zylindern ist zu bemängeln, daß sie sehr schwer sind, und dadu@ch die Nutzlast des Kranes verringert wird. Ais nächstes wäre zu bemängeln daß sie zu teuer sind im Verhältnis zur gesamten Krananlage.One of the complaints about these hydraulic cylinders is that they are very heavy are, and thereby the payload of the crane is reduced. Ais next would be to complain that they are too expensive in relation to the entire crane system.
Der Er@indung liegt die Aufgabe zugrunde, den Teleskopausleger bei gleichen äußerlichen Abmessungen, leichter und billiger herstellen zu können.The invention is based on the task of attaching the telescopic boom same external dimensions, easier and cheaper to manufacture.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß man die Bewegung des Telekopauslegers mit zrei Seilen und einigen Seilrollen ausführt.According to the invention, this object is achieved in that the movement of the telescopic boom with three ropes and some pulleys.
Funktion der Seilbetätigung: Ein Seil wird an der Seiltrommel festgemscht. Dann wird es durch die Seilrollen bis zur Spitze des Teleskopanslegers geführt und geht auf der gegenüberliegenden Seite des Teleskopauslegers durch die Seilroll@n sur Seiltrommel zurück. Wenn das Seil auf der Seiltrommel aufgespultwird, wird der Teleskopausleter austeleskoplert. Durch abspulen des Seiles wird der Teleskopausleger wieder einteleskopiert Wenn der Teleskopausleger steil steht wird er durch sein Eigengewicht einfahren.Function of the rope actuation: A rope is fixed to the rope drum. Then it is guided through the pulleys to the top of the telescopic jib and goes through the pulley @ n on the opposite side of the telescopic boom sur rope drum back. When the rope is wound onto the rope drum, will the Teleskopausleter telescopes out. The telescopic boom is opened by unwinding the rope telescoped in again If the telescopic boom is steep, it will be through Retract dead weight.
Da der Teleskopausleger aber auch bei flacher Stellung einziehbar sein muß, wird ein Seil am letzten Teleskopteil befestigt, und durch löcher im Boden der übrigen Teleskopteile zur Seiltrommel geführt. Dort wird es entgegengesetzt dem ersten Seil aufgespult. Wenn man den Teleskopausleger austeleskopiert hat und ihn einteleskopieren möchte, muß man das erstgenannte Seil von der Selltrommel abspulen.Since the telescopic boom can also be retracted in a flat position must be, a rope is attached to the last part of the telescope, and through holes in the floor the remaining telescopic parts led to the cable drum. There it is opposed wound onto the first rope. When you have extended the telescopic boom and If you want to telescope him in, you have to uncoil the first-mentioned rope from the drum.
Dadurch wird das zweitgenannte Seil aufgespult, und zieht den Teleskopausleger zusammen.As a result, the second-named rope is wound up and pulls the telescopic boom together.
Schrägeinban der Seilrollen: Das Seil muß an den Enden der einzelnen Teleskopteile von außen nach innen geführt werden.Inclined installation of the pulleys: The rope must be at the ends of each Telescopic parts are guided from the outside to the inside.
Der Radius der einzelnen Seilrollen darf nicht zu klein gewählt werden, da das Seil sonst einen zu starken Verschleiß hat. Zu große Sei@@ollen ergeben aber sehr breite Baumaße an den Seiten der einzelnen Teleskopteile.The radius of the individual pulleys must not be too small, otherwise the rope will wear out too much. Too large should be @@ but result very wide dimensions on the sides of the individual telescope parts.
Durch einen schrägen bau der Seilrollen wird der Teleskopausleger nicht a breit und das Seil wird gleich richtig .The telescopic boom becomes due to the inclined construction of the rope pulleys not a wide and the rope will be right.
geführt, das heißt, es kommt von außen oben und geht nach innen unten.guided, that is, it comes from outside above and goes inwards below.
