[0002] A steel structure bridge is a bridge constructed by welding and assembling steel structural parts. When inspecting a hook structure bridge, it is inconvenient for the staff to climb and stand, so a special inspection platform is needed. For example, in the prior art, the announcement number CN214828839U discloses a steel structure bridge inspection device, including an inspection platform, a U-shaped bracket is fixedly connected to the bottom of the inspection platform, a generator is fixedly connected to the inner wall of the U-shaped bracket, a lifting plate is arranged on the upper surface of the inspection platform, and the front and rear sides of the inspection platform are fixedly connected to the limit frame. The utility model is provided with an inspection platform, a lifting plate, a limit frame, a limit column, a pushing mechanism, a pushing block and a spring, wherein the pushing block is a trapezoidal block, and the side of the pushing block close to the pushing mechanism is an inclined surface. When the distance between the lifting plate and the inspection platform needs to be adjusted, the hydraulic push rod is opened to make the pushing disc contact the inclined surface of the pushing block, and the pushing disc pushes the pushing block, so that the pushing block moves upward under the action of the pushing disc. At this time, the distance between the lifting plate and the bridge can be adjusted according to the height of the inspector.

[0003] In actual use, since the inspection surface inside the bridge frame is relatively large, the inspection platform must be moved to the next inspection point after inspecting one area. The existing inspection platform only adjusts the vertical height by lifting and lowering, which cannot solve the problem of limited inspection surface, restricts the movement of operators, brings inconvenience to use, and needs further improvement.
