The utility model provides a portable formula can manual regulation's track detection dolly relates to track detection technical field, including connecting rod one, the both ends fixed mounting of connecting rod one has the car body. The utility model discloses a 6x6
capacitor sensor matrix is installed in the car body bottom, can more accurately detect the damage condition of track surface and inside, cooperate the image information that OpenMV camera gathers, control terminal comprehensive analysis, has improved the accuracy of track damage identification greatly, effectively solved the problem of low detection accuracy of existing track detection car, in addition, through adopting hand -operated lifting wheel, the staff can manually adjust the distance between car body and track according to track height, make the dolly can nimblely adapt to the track detection demand of different height, at the same time, the flexible rotation of the OpenMV camera driven by the
steering wheel can realize multi -angle detection and
obstacle avoidance, greatly enhanced the flexibility of track detection dolly work in different track environment.
