Cantilever crane device for track type dynamic compactor
The invention discloses a cantilever crane device for a track type dynamic compactor, and relates to a lifting mechanism of the track type dynamic compactor. The cantilever crane device is mainly formed by welding multiple main chord pipes (1) and web pipes (2), wherein the main chord pipes (1) adopt rectangular seamless steel pipes, and are welded to form cantilever cranes with rectangular unit sections; the web pipes (2) are welded along the diagonal lines in the sections of all the unit cantilever cranes, and are distributed in a rhombus form in the whole cantilever crane section; and the two ends of the main chord pipes (1) are welded with connecting flanges (3). The cantilever crane device is simple in structure; the main chord pipes adopt the rectangular seamless steel pipes, and the web pipes adopt the seamless steel pipes, so that the cantilever crane weight is reduced, the manufacturing cost is reduced, and the cantilever crane rigidity is improved; and the connection of all sections of the cantilever cranes adopts the flanges, so that the connecting gaps of the cantilever cranes are decreased, the whole strength of the cantilever cranes is increased, the stability of the cantilever cranes is enhanced, and the service life is prolonged.
