Walking type jacking and pushing device

The utility model discloses a walking type jacking and pushing device for bridge construction. The jacking and pushing device comprises bearing sleeper beams, beam placing seats, longitudinal sliding ways, a jacking and lifting mechanism and a pushing mechanism; and the lifting of the jacking and lifting mechanism and the translation of the pushing mechanism are controlled by a control circuit. The walking type jacking and pushing device performs jacking and pushing construction in a sequence of jacking, pushing, descending and contracting in a reciprocating and circulating way, so that the jacked and pushed beams can be moved in a vertical direction and along the bridge direction, and the limit, adjustment and movement of the jacked and pushed beams in a vertical direction, a direction along the bridge and a transverse direction of the bridge direction can be realized. The requirement of the most advanced walking type jacking and pushing process technology at present can be fully met; the walking type jacking and pushing device is simple in structure, and low in purchasing and using cost; and a walking type jacking and pushing process technology can be popularized and applied conveniently.
