1. in order to realize the functions of fixing and protecting the wire and avoiding vibration, the shockproof hammer, the strain clamp, the suspension clamp and the like become indispensable devices on the wire, and the indispensable devices become typical barriers on the power transmission line, but the existing inspection robot is poor in barrier crossing function and cannot well cross the barriers by itself, so that inspection efficiency is affected;
2. in a high-voltage transmission line, because the requirements of the bearing electric performance of different positions are different, the requirements of conveying different voltages and currents are required to be met, and therefore, the thicknesses of the cables at different positions are different, but the existing inspection robot is only suitable for walking on the cable with the consistent thickness, and when the thickness of the cable changes, the enclasping operation with the cable cannot be well completed, so that the normal inspection work is influenced;
3. the high-voltage transmission line is generally more than ten meters in height, wind power is often very large, and the existing line inspection robot is simple in connection mode and poor in fixing effect with a cable line, so that weak transverse wind resistance and poor stability are prevented, the condition that the line inspection robot is shaken greatly or even falls due to wind blowing is easily caused, interruption and data errors in the inspection process are easily caused, and potential safety hazards exist.
