The invention belongs to the technical field of the power line operating maintenance, and specifically relates to a turnover-type steel pipe pole tower climbing detection device. The device comprisestwo groups of annular clamping devices, an automatic turnover device provided with a turnover pole tower detection unit, and a central control monitoring device; two groups of annular clamping devicesare rotatably connected with the upper end and the lower end of the automatic turnover device; the central control monitoring device controls two groups of annular clamping devices to clamp or release the steel pipe pole tower, controls the movement of two groups of annular clamping devices on the steel pipe pole tower, and controls the turnover of the automatic turnover device and the detectionon the steel pipe pole tower status by the pole tower detection unit through remote control. The detection device disclosed by the invention is relatively simple in structure, safe and reliable, and capable of accomplishing the detection tasks on various pole towers by using the matched equipment.
