Description

Die Erfindung bezieht sich auf eine Einrichtung zum Einziehen des Auslegers von Kranen, die so ausgebildet ist, daß als Wippwerk eine mit Antriebsmotor versehene Kletterkatze verwendet wird. Damit sich die Last beim Heben und Senken des Auslegers waagerecht oder annähernd waagerecht bewegt, wird von der genannten Kletterkatze ein im Krangerüst \rerschiebbarer Wagen beeinflußt,The invention relates to a device for retracting the boom of cranes, which is designed so that a climbing trolley provided with a drive motor is used as the luffing mechanism. Thus, the load horizontally or for lifting and lowering the boom approximately horizontally moved, an influence from said climbing cat in gantry \ r erschiebbarer carriage,

ίο über dessen Rollen das Lastseil in bekannter Weise flaschenzugartig geführt ist. Die zum Einziehen des Auslegers benutzten Mittel, wie Seile, Spindeln o. dgl., stehen hierbei mit der auf- und abwärts gehenden Kletterkatze in Verbindung.ίο on whose roles the load rope in known Way is like a pulley block. The means used to retract the boom, such as Ropes, spindles or the like are here with the climbing cat going up and down Link.

Wie aus der Zeichnung, die den Gegenstand der Erfindung schematisch darstellt, ersichtlich ist, wird der Ausleger α im Punkt b gelenkig am Krangerüst c angeschlossen. Das zum Einziehen benutzte Zugorgan wie Spindel, Seil ο. dgl. d steht einerseits mit dem Ausleger α und andererseits mit der Kletterkatze e in Verbindung, derart, daß bei der Bewegung derselben nach oben oder unten ein Senken bzw. Heben des Auslegers erfolgt. Weiterhin ist an der Kletterkatze e ein Steuerorgan, Seil, Kette ο. dgl. / befestigt, Avelches über die Rollen g, h, i zu einem mit Umlenkrollew versehenen, im Krangerüst verschiebbaren Wagen k geführt ist. Das Lastseil / läuft hierbei von dem Windwerk q über die festen Rollen m und die lose Rolle η des verschiebbaren Wagens· k, eine Schlaufe bildend, zur Schnabelrolle 0 und' von hier zur --Last/».As can be seen from the drawing, which schematically depicts the subject matter of the invention, the boom α is connected to the crane frame c in an articulated manner at point b. The pulling element used for pulling in, such as spindle, rope ο. Like. d is on the one hand with the boom α and on the other hand with the climbing cat e in connection, such that when the same up or down a lowering or lifting of the boom takes place. Further, a control member, rope, chain on the ο cat climbing e. Like. / attached, Avelches is guided over the rollers g, h, i to a carriage k provided with a deflection rollerw and displaceable in the crane frame. The load rope / runs here from the winch q over the fixed pulleys m and the loose pulley η of the movable carriage · k, forming a loop, to the beak pulley 0 and 'from here to the --load / ».

Wie in Abb. ι dargestellt, wird beim Senken der Kletterkatze e der Ausleger α eingezogen, wobei das an der Katze befestigte Steuerorgan, beispielsweise Seil /, eine Bewegung des Wagens k gegen die feste Rolle m bewirkt. Hierdurch erfolgt eine Beeinflussung des am Windwerk q angeschlossenen Lastseiles I derart, daß es durch die Veränderung der zwischen beide Rollen m, 11 gezogenen Schlaufe die an ihm hängende Last in gleicher Höhe beläßt. Bewegt sich die Kletterkatze e nach oben, so senkt sich der Ausleger«, und die genannte Schlaufe innerhalb des Lastseiles I wird vergrößert.As shown in Fig. Ι, when the climbing trolley e is lowered, the boom α is retracted, the control element attached to the trolley, for example a rope /, causing the carriage k to move against the fixed roller m. This influences the load rope I connected to the winch q in such a way that the change in the loop drawn between the two rollers m, 11 leaves the load hanging on it at the same height. If the climbing trolley e moves upwards, the boom lowers and the loop mentioned within the load rope I is enlarged.

Es muß noch darauf hingewiesen werden, .daß die Kletterkatze aus einem mit Antriebsmotor versehenen, sich im Krangerüst auf- und abwärts bewegenden Wagen besteht, der gleichzeitig auch als Gegengewicht für den Ausleger benutzt werden kann.It must also be pointed out that the climbing cat consists of a drive motor provided, moving up and down in the crane frame, which also acts as a counterweight for the Boom can be used.
