Description
Die Erfindung bezieht sich auf einen Wippkran mit von einer Seite des Krangeriistes zur anderen durchschwingendem Ausleger, bei dessen Bewegung sich die Last in waagerechtem Weg am Krangerüst vorbeibewegt.The invention relates to a luffing crane with one side of the crane riser another swinging boom, the movement of which moves the load in a horizontal position Path moved past the crane frame.
Krane dieser Art sind in verschiedener Ausführung bekannt, und zwar sowohl mit geneigt liegender Auslegerschwenkachse wie auch mit waagerecht liegender.Cranes of this type are known in various designs, both with inclined horizontal boom pivot axis as well as with horizontal.
ίο Beide Anordnungen haben bisher den Nachteil, daß die Last nicht quer zur Schwingungsrichtung des Auslegers auf das Krangerüst zu und von demselben ab bewegt werden kann. Dies ist aber vielfach erwünscht, da man dabei den Arbeitsbereich des Kranes erheblich erweitern kann, ohne ihn als Drehkran ausbilden zu müssen.ίο Both arrangements have so far had the disadvantage that the load is not at right angles to the direction of oscillation of the boom towards the crane frame and can be moved from it. However, this is often desired because you are doing it can significantly expand the working range of the crane without training it as a slewing crane to have to.
Die Erfindung bietet diese Möglichkeit, und sie besteht darin, daß die Schwenkachse des Auslegers verstellbar so im Krangerüst gelagert ist, daß sie sowohl waagerecht wie rauch in verschiedene Neigungswinkel vor oder während des Betriebes eingestellt werden kann.The invention provides this possibility, and it consists in that the pivot axis of the boom is so adjustably mounted in the gantry so that it can be set as r in different angles of inclination before or during operation both horizontally.
Auf der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäß ausgebildeten Kranes dargestellt, bei dem der Kran als Schwimmkran ausgebildet ist.The drawing shows an embodiment of a crane designed according to the invention shown, in which the crane is designed as a floating crane.
Der Ausleger 1 ist um die Achse 2 zwischen einem vorderen Gerüst 3 und einem hinteren Gerüst 4 schwenkbar angeordnet. Die Lager 5 und 6 der Schwenkachse 2 sind ihrerseits selbst als Schwenklager ausgebildet. Das vordere Lager 5 ist am oberen Ende des das Führerhaus 7 tragenden vorderen Gerüstes 3 um einen Festpunkt drehbar gelagert, während das hintere Lager 6 in einer nach vorn etwas überragenden Kulisse 8 des hinteren Gerüstes 4 mittels eines die Lagerzapfen 9 aufnehmenden Steines 10 verschiebbar geführt ist. In dem hinteren Schwenklager 6 ist die Schwenkachse 2 axial verschiebbar, während sie im vorderen Lager 5 gegen Axialverschiebung gesichert ist. Die Verstellung des hinteren Schwenklagers 6 in der Kulisse 8 erfolgt mit Hilfe einer an dem Kulissenstein 10 festgelegten, nicht drehbaren Schraubenspindel 11, auf der eine außen als Schnecke ausgebildete Mutter 12 sitzt. Diese wird durch den Motor 13 mittels der auf seiner Welle sitzenden Schnecke 14 angetrieben.The boom 1 is around the axis 2 between a front frame 3 and a rear one Scaffold 4 arranged to be pivotable. The bearings 5 and 6 of the pivot axis 2 are themselves designed as a pivot bearing. The front bearing 5 is at the top of the cab 7 supporting front frame 3 rotatably mounted about a fixed point, while the rear Bearing 6 in a forward slightly protruding gate 8 of the rear frame 4 by means of a bearing pin 9 receiving Stone 10 is slidably guided. The pivot axis 2 is located in the rear pivot bearing 6 axially displaceable, while it is secured in the front bearing 5 against axial displacement. The adjustment of the rear pivot bearing 6 in the link 8 takes place with the help of an on the Sliding block 10 fixed, non-rotatable screw spindle 11, on which an outside as Snail-trained nut 12 is seated. This is by the motor 13 by means of the on his Shaft seated screw 14 driven.
Um den waagerechten Lastweg zu sichern, ist das Lastseil 15 in an sich bekannter Weise über einen Flaschenzug 16 geführt, dessen Rollen einerseits am Auslegerschwanz und andererseits am Fuße des vorderen Krangeriistes 3 angeordnet sind.In order to secure the horizontal load path, the load rope 15 is in a manner known per se guided over a pulley 16, the roles of which on the one hand on the boom tail and on the other hand are arranged at the foot of the front Krangeriistes 3.
Der Antrieb des Auslegers und des Lastseiles kann in beliebiger Weise erfolgen.The boom and the load rope can be driven in any way.
Wie aus der Zeichnung ohne weiteres ersichtlich ist, kann man mit dem dargestellten Kran sowohl nach vorn, d. h. vor dem Ponton, arbeiten wie auch nach beiden Seiten desselben. Ebenso ist man bei Uferkranen in der Lage, von der Wasserseite, d. h. von einem Schiff aus sowohl unmittelbar in axialer Richtung der Schwenkachse 2 nach dem Ufer zu sowie am Ufer nach beiden Seiten der Schwenkachse, also z. B. nach mehreren hintereinanderstehenden Waggons, zu arbeiten (Abb. 2) oder auch übereck von Schiff zu Schiff (Abb. 3), ohne daß der Kran selbst gedreht werden müßte.As can be readily seen from the drawing, you can use the crane shown both forward, d. H. work in front of the pontoon, as well as on both sides of the same. In the case of bank cranes, you are also able to work from the water side, i.e. H. from a ship both immediately in the axial direction of the pivot axis 2 after the bank and on Bank on both sides of the pivot axis, so z. B. after several consecutive Wagons to work (Fig. 2) or even across the board from ship to ship (Fig. 3) without the crane would have to be rotated.
Die Anordnung der Kulisse oder des darin verschiebbaren Schwenklagers kann natürlich auch anders erfolgen als dargestellt, und zwar kann man die Kulisse z. B. auch kreisbogenförmig um den festen Schwenkpunkt der Achse 2 herumlegen, Dabei muß die Schraubenspindel natürlich selbst mit ihrer Mutter schwenkbar angeordnet sein, doch braucht die Achse 2 in dem verschiebbaren Lager nicht axial verschiebbar zu sein.The arrangement of the backdrop or the pivot bearing displaceable therein can of course also take place differently than shown, namely you can use the backdrop z. B. also circular arc around the fixed pivot point of axis 2, the screw spindle of course, be arranged pivotably even with its mother, but needs the axis 2 in the displaceable bearing not to be axially displaceable.
Selbstverständlich kann statt des hinteren Lagers 6 gegebenenfalls auch das vordere Lager 5 in der Höhe verstellbar angeordnet sein.Of course, instead of the rear bearing 6, the front bearing 5 can optionally also be used be arranged adjustable in height.
