Railway bridge dynamic deflection wireless detection device

The utility model relates to the technical field of railway bridge detection equipment, and discloses a railway bridge dynamic deflection wireless detection device which comprises a fixing plate, a damping device is fixedly installed at the top of the fixing plate, a connecting block is fixedly installed at the bottom of the fixing plate, and a supporting rod is rotatably installed on the inner surface of the connecting block. A fixed rotating block is rotatably mounted on the inner surface of the supporting rod, a clamping rod is mounted on the inner surface of the fixed rotating block in a threaded mode, and a rotating block is fixedly mounted on the outer surface of the clamping rod. A worker opens the fixed rotating block and fixes the clamping rod in the fixed rotating block, the worker rotates the rotating block and rotates the clamping rod into soil, and due to the fact that the clamping rod is hollow, the soil can be squeezed out of the clamping rod, and firmness can be improved. 本实用新型涉及铁路桥梁检测设备技术领域，且
