Technical Field
[0001] The utility model relates to the technical field of railway power line maintenance, in particular to a railway power line foreign matter removing device. Background Art
[0002] As railway power lines operate in the natural environment for a long time, foreign objects are often trapped on the power lines. For example, foreign objects such as agricultural greenhouse plastic, sunshade nets, woven belts, advertising cloth, kites and kite ropes are entangled on the power lines due to wind and other reasons. Since the retention of foreign objects will affect the safety of railway transportation and the stable operation of the power system, it is necessary to remove the foreign objects on the railway power lines. The existing removal methods include laser removal, drone removal and manual removal. In the process of manually using an insulating rod to remove foreign objects on the railway power lines, the operator needs to hold the insulating rod in his hand all the time to remove the foreign objects. The insulating rod is long and heavy overall. Therefore, when the operator continues to hold the insulating rod to remove foreign objects on the railway power lines, the labor intensity is high and it is easy to cause arm fatigue and soreness. Therefore, a railway power line foreign object removal device is proposed to address the above problems. Utility Model Content
