In recent years, ultrahigh voltage and extra-high voltage power grids are being constructed and put into production on a large scale in China. The ultra-high voltage and ultra-high voltage transmission line has the characteristics of wide area span, high ground distance, complex path environment, large risk of three spans (crossing high-speed railways, expressways and important transmission channels), variable meteorological disasters and the like. When the power line construction is carried out in the field, particularly in the high-altitude working environment of extra-high voltage and extra-high voltage transmission lines, the danger is high, when workers work on iron towers or cables between the iron towers, the workers are easy to fall off the cables if the workers step on the iron towers or carelessly sunstroke or other conditions occur, and the workers are suspended in the air only by the safety belts.

In the prior art, generally, rescue is carried out by other people on the tower, if the falling personnel are insufficient in physical strength, the falling personnel can only reach the falling point by other rescue personnel, the falling personnel are pulled by the safety belt, the falling personnel are pulled back to the cable, the falling personnel are carried on the back to the iron tower from the cable, and finally the iron tower is carried on the back for treatment, so that the rescue difficulty of complicated operation is very high, the rescue time is greatly consumed, and the rescue success rate is low. If the falling personnel have injury conditions needing emergency treatment, the best rescue time is likely to be missed by the rescue mode.

Another rescue method is to connect the safety belt with a safety rope and then lower the safety rope so that the falling person can fall to the ground from between the falling points. However, the connection reliability of the safety rope and the safety belt is not high, and more tall trees generally exist between the two iron towers, and when the two iron towers directly fall from a falling point downwards, the trees are possibly clamped when the two iron towers fall, so that the rescue difficulty is increased again. In addition, when the cable is located at a high altitude, due to the blurred vision and wind, the appropriate drop point cannot be clearly determined.
