In the daily operation process of a power transmission line, the situation that barrier foreign matters such as plastic garbage, kites and the like blown by strong wind are wound and hung on the power transmission line often occurs, and the occurrence of the situations aggravates the vibration of the power transmission line, causes the damage of a power grid structure and even causes flashover or short circuit damage. For the obstacles, at present, line maintenance workers mostly climb onto an electric tower by means of tools such as rope ladders, shielding clothes, insulating rods and the like to remove the nearby obstacles. And the obstacle far away from the electric tower can only remove foreign matters by repeatedly dragging and rubbing the obstacle by a ground worker through hanging a thick rope. The methods need line maintenance workers to carry out high-altitude live working, and have the disadvantages of high labor intensity of the workers, low efficiency, high risk coefficient and high requirement on professional quality of the workers.

CN 201710327991-8 discloses a transmission line of remote control flame projecting removes barrier device, relies on the flame projecting mode to clear away the circuit barrier, and this utility model flame projecting nozzle arranges the circuit below in, relies on the running block to realize the motion on the circuit. The utility model discloses a there is certain design drawback in the practice, often has equipment such as stockbridge damper on the high tension transmission line, and this kind of walking coaster can not be through these equipment, will unable realization free skating along the line.

And in the utility model, obstacles such as kite lines in the free state are difficult to cut off only by one rotary saw blade, so that the machine is easy to wind and the consequence of walking is difficult to occur.

However, the swing arm walking mode has low efficiency and poor equipment balance. Foreign matters are often distributed on the high-voltage line far away from the fixed electric tower, and the obstacle removal through long-distance walking of the swing arm can cause insufficient power supply, and when the high-voltage line is arranged in a large-gradient oblique manner, climbing is difficult to realize only by a swing arm walking mode, and obstacle removal operation cannot be realized at all.
