Operation stability monitoring device for bridge detection vehicle

The invention discloses an operation stability monitoring device for a bridge detection vehicle, which comprises a workbench, a light emitting mechanism and a light receiving mechanism are fixedly installed on one side wall of the workbench, and the light emitting mechanism and the light receiving mechanism are located on the same horizontal plane. The device has the beneficial effects that the horizontal position of the laser pen can be adjusted through the horizontal adjusting mechanism, the height of the laser pen can be adjusted through the height adjusting mechanism, light rays can be emitted through the laser pen, the light rays are emitted into the calibration ring on the receiving plate, and when the workbench shakes, the light spot position on the receiving plate deviates. The larger the shaking amplitude of the workbench is, the larger the offset distance of the light spot is, so that the shaking degree of the workbench is observed, and the stability of the workbench can be accurately monitored. 本发明
