Mounting structure for tilt angle sensor of bridge erecting machine

The utility model discloses a mounting structure for a tilt angle sensor of a bridge girder erection machine, which comprises a shell with an opening on one side and a shielding layer with an opening on one side, the shell is nested outside the shielding layer, the tilt angle sensor is arranged in the shielding layer, and the shell, the shielding layer and the tilt angle sensor are fixed together through fixing pieces. A magnet which can be attracted on the bridge girder erection machine is arranged on the opposite side of the outer opening of the shell; a grounding body penetrates through the shielding layer and the shell and is respectively contacted with the tilt angle sensor and the bridge girder erection machine; the mounting structure is fixed on the bridge girder erection machine through the magnet, protects the tilt angle sensor through the shell, prevents the magnet from interfering detection of the tilt angle sensor through the shielding layer, prevents the tilt angle sensor from being struck by lig
