This utility model proposes a suspended platform for bridges, comprising: a platform body, a swing arm, a damping wheel, and a spring rod. The platform body is suspended from the lower part of the bridge by steel cables. A guardrail is provided around the outer perimeter of the platform body, and a mounting base and an extension rod are provided on the guardrail. One end of the swing arm is hinged to the mounting base, and the damping wheel is mounted on the other end of the swing arm. One end of the spring rod is hinged to the end of the extension rod. This utility model, by setting a swing arm on the guardrail, presses the damping wheel against the bottom of the bridge under the action of the spring rod. When the platform body sways, the damping wheel rotates. The damper can resist the rotation of the damping wheel, converting kinetic energy into internal energy, allowing the platform body to quickly eliminate swaying. The swing arm's swing allows the damping wheel to adjust itself according to the curvature of the bridge bottom, adapting to different bridge types.
