Description
Die Erfindung bezieht- sich auf die Ausführung der Abstützarme sowie die dazugehörigen Ausschwenklager für Eisenbahn- sowie straßengängige Krane usw.The invention relates to the execution of the support arms as well the associated swivel bearings for railway and road cranes, etc.
Die Ausschwenkarme besitzen im allgemeinen als Drehpunkte Laschen, die oben und unten an den entsprechenden Trägern des Kranunterwagens angebracht und um diese schwenkbar sind. Im abgestützten Zustand des Kranes werden die Laschen stark auf Biegung sowie Zug und Druck beansprucht und sind deshalb meist als massive Gußstücke ausgeführt.The swivel arms generally have tabs as pivot points, which are attached to the corresponding beams of the crane undercarriage at the top and bottom and can be pivoted about them. When the crane is supported, the lugs are strongly stressed on bending as well as tension and pressure and are therefore mostly considered massive Castings executed.
Erfindungsgemäß sollen die Laschen von allen Biegungsmomenten entlastet werden. Die Kräfte werden deshalb in Horizontal- und Vertikalkräfte zerlegt, und es wird durch zweckmäßige Konstruktion erreicht, daß die Laschen nur noch Horizontal-, also Zug- oder Druckkräfte aufzunehmen haben. Die Vertikalkräfte werden nicht über die Laschen, sondern über scharnierartige Hülsen direkt auf den Steg des I-Querschnittes des Abstützarmes weitergeleitet. Sinngemäß erfolgt die Kräfteleitung ebenso bei allen anderen Querschnitten der Abstützarme.According to the invention, the brackets should be relieved of all bending moments will. The forces are therefore divided into horizontal and vertical forces, and it is achieved by an appropriate construction that the tabs only horizontal, thus have to absorb tensile or compressive forces. The vertical forces are not over the tabs, but via hinge-like sleeves directly on the web of the I cross-section of the support arm forwarded. Correspondingly, the forces are also directed at all other cross-sections of the support arms.
Eine erfindungsgemäße Ausführungsforiri zeigt die Abbildung. In dem Träger F am Kranunterwagen sitzt der Bolzen 2 als Drehpunkt für die Abstützarme, welche mit den Laschen 3 und 4 um den Bolzen :2 schwenken. Die Vertikalkräfte werden von der Hülse 5 am Oberwagen auf das Hülsensegment 6 und von dort auf den Steg 7 des Abstützarmes weitergeleitet. Die Laschen 3 und 4 haben somit nur noch Horizontalkräfte aufzunehmen und können demnach entsprechend leicht ausgeführt werden.An embodiment according to the invention is shown in the figure. By doing Beam F on the crane undercarriage has bolt 2 as a pivot point for the support arms, which with the tabs 3 and 4 around the bolt: 2 swivel. The vertical forces will be from the sleeve 5 on the superstructure to the sleeve segment 6 and from there to the web 7 of the support arm forwarded. The tabs 3 and 4 therefore only have horizontal forces and can therefore be carried out easily.
Durch diese Anordnung ergibt sich eine wesentliche Gewichts- und damit Kostenersparnis gegenüber den bisherigen Ausführungen.This arrangement results in a significant weight and thus Cost savings compared to the previous versions.
