Sliding adjusting type steel box girder hanging bracket

The utility model relates to a sliding adjusting type steel box girder hanging bracket which comprises a main longitudinal beam, a cross beam sliding end, a sliding cross beam, a force bearing slider, an n-shaped clamping groove type sliding cross beam, an I-shaped large-size cross beam, a supporting truss, a sliding steel sleeve, a steel rope winding drum and a steel box girder. The inner and outer sliding cross beam structures of the hanging bracket can slide along the longitudinal beams, the gravity center can be adjusted according to the size of the steel box girder, the stability of the gravity center of the hanging bracket is effectively guaranteed through the sliders, the stability of the gravity center of the steel box girder is effectively guaranteed through the sliding steel sleeves, and the large-size steel box girder can be rapidly and accurately hung to a to-be-installed position; and the hoisting efficiency of the steel box girder is improved, and good economic and technical benefits are achieve
