Fabricated I-shaped bridge detection working platform

The utility model discloses an assembly type I-shaped bridge detection working platform, which belongs to the technical field of bridge detection and maintenance equipment and is characterized in that a plurality of pairs of spherical walking wheels with adjustable intervals are arranged on the detection working platform, and the spherical walking wheels with the adjustable intervals can be clamped on a lower horseshoe of an I-shaped beam. The detection working platform is suspended between the two I-shaped beams and walks in the span direction of the I-shaped beams; the detection working platform ingeniously utilizes the shape of the lower horseshoe of the I-shaped beam, and can be suspended between the two I-shaped beams and walk through the paired spherical walking wheels, so that detection personnel can detect the lower part of the bridge, and meanwhile, the detection working platform only needs to adapt to the distance between the two I-shaped beams; the size and the weight of the detection working platf
