Description
Eisenbahn-Auslegerkran Die Erfindung betrifft einen Eisenbahn-Auslegerkran mit am Fuße des Kranhauses angelenktem winkelförmigen Ausleger, dessen Schenkel gegeneinander verstellbar sind und der mit zwei Einziehwerken versehen ist. Das eine Einziehwerk dient zum Ausschwenken des Gesamtauslegers, und das andere Einziehwerk ist in neuartiger Weise dazu bestimmt, die Streckung des niedergelegten Auslegers zum Durchfahren des Eisenbahnprofils und eine Vergrößerung der Rollenhöhe des aufgerichteten Auslegers herbeizuführen.Railway jib crane The invention relates to a railway jib crane with angled boom hinged at the foot of the crane house, the legs of which are mutually adjustable and which is provided with two draw-in mechanisms. That one retraction mechanism is used to swivel out the entire boom, and the other retraction mechanism is designed in a new way to increase the extension of the laid boom for driving through the railroad profile and increasing the roller height of the erected one Bring about boom.
In der Zeichnung ist der Erfindungsgegenstand in zweiAusführungsformen je in Ruhe-, Arbeits- und Beförderungsstellung beispielsweise veranschaulicht.In the drawing, the subject of the invention is in two embodiments each illustrated in the rest, work and promotion position, for example.
Abb. z zeigt einen Kran mit winkelförmigem Ausleger b1, b2, der in bekannter Weise mit Hilfe eines Einziehwerkes a heruntergelassen und eingezogen werden kann. Die gestrichelte Stellung I (Abb. r) des Auslegers zeigt, wie dieser bei völligem Niederlegen noch über das Eisenbahnprofil p hinausragt. Um den Ausleger innerhalb desselben unterzubringen, hat er eine bewegliche Knickstelle d, an der das zweite Einziehwerk A angreift. Dieses kann den Ausleger aus Stellung I (Abb. r) entweder in die Lage II oder Stellung III bringen, je nachdem die Stabilitätsverhältnisse des Kranes dieses gestatten. Das zweite Einziehwerk A bietet weiter den Vorteil, daß die Rollenhöhe in der höchsten Auslegerstellung vergrößert werden kann (Stellung IV, Abb. r). Das zweite Einziehwerk kann maschinell oder von Hand nach bekannten Ausführungen bewegbar sein, und es ist ohne Belang, ob dieses im Ober- oder Untergurt liegt. In Abb. 3 .ist ein Eisenbahn-Auslegerkran dargestellt, der zum Einstellen in Eisenbahnzüge eingerichtet ist. Der Ausleger b1, b2 ist mit dem üblichen Einziehwerk a ausgerüstet. Außer diesem ist ein zweites Einziehwerk A vorgesehen, das an der Knickstelle d angreift.Fig. Z shows a crane with an angled boom b1, b2, which can be lowered and retracted in a known manner with the aid of a pull-in mechanism a. The dashed position I (Fig. R) of the boom shows how it protrudes beyond the railroad profile p when it is completely laid down. In order to accommodate the boom within it, it has a movable kink d on which the second draw-in mechanism A engages. This can move the boom from position I (Fig. R) either into position II or position III, depending on the stability of the crane. The second draw-in mechanism A also offers the advantage that the roller height can be increased in the highest boom position (position IV, Fig. R). The second retraction mechanism can be moved by machine or by hand according to known designs, and it is irrelevant whether it is in the upper or lower belt. Fig. 3 shows a railway jib crane that is set up for use in railway trains. The boom b1, b2 is equipped with the usual draw-in mechanism a. In addition to this, a second drawing-in mechanism A is provided, which engages at the kink d.
Arbeitet der Kran, so steht der untere kurze Auslegerteil b1 so weit zurück, daß er das Eisenbahnprofil p des Nebengeleises frei läßt (Abb. 3). Soll dagegen der obere Ausleger b2 zurückgeklappt werden, so würde derselbe an sich weit über den Unterwagen des Kranes hinausragen. Es wäre entweder ein Schutzwagen erforderlich, oder die Plattform des Wagens, müßte entsprechend länger gewählt werden. Die größere Länge des Unterwagens beeinflußt jedoch die nutzbare Ausladung des Kranes in seiner Geleisrichtung ungünstig. Mit Hilfe des zweiten Einziehwerkes A kann indessen der Drehpunkt d des oberen Auslegers und damit dieser selbst nach rechts verschoben werden, so daß die Plattform erheblich verkürzt werden kann.When the crane is working, the lower short jib part b1 is so far back that it leaves the railroad profile p of the side track free (Fig. 3). If, on the other hand, the upper boom b2 is to be folded back, it would in itself protrude far beyond the undercarriage of the crane. It would be either a barrier wagon required or the platform of the carriage must be chosen longer. However, the greater length of the undercarriage has an unfavorable effect on the usable radius of the crane in its direction of the track. With the help of the second retraction mechanism A , however, the pivot point d of the upper boom, and thus the latter itself, can be shifted to the right, so that the platform can be shortened considerably.
