Bridge slope adjusting integral jacking device

The utility model relates to the technical field of bridges, in particular to a bridge slope adjusting integral jacking device which comprises a cover beam, a steel corbel is arranged on the surface of the cover beam, and a jack for replacing a support is arranged on the surface of the steel corbel. A limiting hole is formed in the surface of the column embracing beam; longitudinal limiting bailey beams are arranged between the bridge piers; the self-locking jack has the beneficial effects that the jacks are all self-locking jacks, automatic locking can be achieved in time through a mechanical lock in the jacking process of the jacks, accidents such as hydraulic leakage or sealing oil leakage are avoided, and good safety is achieved; the bulb at the top of the jack automatically adjusts the bulb at the top of the cylinder along with the change of the gradient of the upper structure, so that the vertical stress of the jack is ensured, and the major risk of failure of the jack caused by overlarge horizontal unb
