Safe anti-falling device for bridge construction

The invention discloses a bridge construction safety anti-falling device which comprises a base, a stable shell is fixed to the center of the bottom of the base, lifting adjusting assemblies are fixedly installed at the four corners of the bottom of the base correspondingly, universal wheels are fixedly installed at the bottom ends of the lifting adjusting assemblies, and reciprocating translation assemblies are symmetrically and fixedly installed on the front side and the rear side of the upper surface of the base. A movable plate is fixedly mounted between the two reciprocating translation assemblies, a reciprocating lifting assembly is fixedly mounted on the upper surface of the movable plate, and a protective shell with an opening in the upper end is fixedly mounted on one side of the reciprocating lifting assembly. In the bridge construction process, falling sundries can be well shielded and protected, threats to personal safety on the lower side of a bridge are avoided, automatic adjustment movement and
