The invention discloses a camera balancing device for a mine inspection robot, and relates to the technical field of coal mining safety. The balancing device comprises a computer, a camera device bottom plate, a platform, an angle sensor mounted at the center of the camera device bottom plate and two sets of hydraulic cylinder mechanisms symmetrically mounted between the camera device bottom plateand the platform. The angle sensor and the hydraulic cylinder mechanisms are electrically connected with the computer separately, the angle sensor measures the angle of inclination of the camera device bottom plate and sends the result to the computer, and after processing and analysis by the computer, the hydraulic cylinder mechanisms move to carry out the left and right balance adjustment of the camera device bottom plate. According to the camera balancing device, the method of the combination of the hydraulic cylinder mechanisms and the angle sensor is adopted to adjust the angle in the left and right directions at the same time, so that the adjustment is faster and more accurate, during the non-horizontal movement of the inspection robot, the camera device is always kept in balance tokeep a picture in a horizontal state, and thus the stability of the inspection picture is ensured.
