Overhead line icing automatic clearing device

The utility model relates to an overhead line ice coating automatic clearing device which comprises a deicing cutter head, a driving assembly, a moving assembly and a thrust balancing assembly. The deicing cutter head, the moving assembly and the thrust balancing assembly are all connected with the driving assembly, the driving assembly drives the moving assembly to drive the automatic overhead line icing clearing device to integrally move along the overhead line, and the driving assembly drives the deicing cutter head to rotate along the axis of the overhead line so as to remove ice. The deicing cutter head and the moving assembly are arranged in the moving direction of the automatic overhead line icing clearing device, the thrust balancing assembly is located between the deicing cutter head and the moving assembly, and the thrust balancing assembly is used for bearing forward resistance applied to the deicing cutter head. The beneficial effects are that the thrust balance assembly is located between the dei
