Road bridge jacking bracket

The utility model belongs to the technical field of road bridges and particularly relates to a road bridge jacking bracket. The road bridge jacking bracket comprises a bottom support block which is symmetrically arranged, wherein a horizontal bracket is arranged at the upper end of the bottom support block; the horizontal bracket is connected to the bottom support block through oblique brackets; the road bridge jacking bracket is characterized in that the horizontal bracket comprises a telescopic fixing ring in the middle; the telescopic fixing ring radially extends outwards to form horizontal support arms which are uniformly distributed along the periphery of the telescopic fixing ring; one end of each oblique bracket is hinged to the outer end of the corresponding horizontal support arm; the other end of each oblique bracket is hinged to the bottom support block; jacks are arranged on the horizontal support arms. The road bridge jacking bracket has the advantages that the telescopic fixing ring can be adjusted according to the diameter of specific piers; specifically, adjacent arc-shaped ring bodies generate extension and retraction and are closely fit with the outer walls of the piers; the arc-shaped ring bodies are highly flexibly; the arc-shaped ring bodies and the outer walls of the piers hard slide relatively; the road bridge jacking bracket is high in safety.
