Rear crossbeam and main girder connecting structure for self-propelled movable formwork
The invention discloses a rear crossbeam and main girder connecting structure for a self-propelled movable framework. The rear crossbeam and main girder connecting structure comprises a triaxial rotating mechanism; the triaxial rotating mechanism comprises transverse moving frames, hanging rods, lifting lugs, transverse moving bases and transverse moving oil cylinders, wherein the lower end of each transverse moving frame is hinged to the upper end of the corresponding hanging rod through a transverse pin shaft; each transverse pin shaft is arranged in a transverse direction; the lower end of each hanging rod is hinged to the upper end of the corresponding lifting lug through a longitudinal pin shaft; each longitudinal pin shaft is arranged in a longitudinal direction; two ends of each transverse moving oil cylinder are respectively hinged to the corresponding transverse moving frame and the corresponding transverse moving base; each transverse moving frame and the corresponding transverse moving base are respectively suspended on a rear crossbeam of the self-propelled movable formwork; each transverse moving base is connected with a rear crossbeam of the self-propelled moving formwork; each transverse moving frame is positioned in the inner side of the corresponding transverse moving base; the lower part of each lifting lug extends to a main girder of the self-propelled moving formwork, and the main girder of the self-propelled moving formwork can rotate around the lifting lugs; the lifting lugs are vertically arranged. According to the rear crossbeam and main girder connecting structure disclosed by the invention, the stress concentration phenomenon generated when local transverse and longitudinal bending moments at the connecting part between the rear crossbeam and the main girder are relatively large is avoided, and the safety of small-radius horizontal curve bridge construction is ensured.
