The invention discloses a cable patrol and snow removal robot which comprises a box body, wherein the box body is provided therein with a box body cavity; the box body is provided therein with two boxbody auxiliary cavities which are bilaterally symmetrical and communicate with the box body cavity. A spanning device is disposed in the box body cavity, and has an upper end hinged to the lower endof a rocker arm device. The spanning device is hinged to two bilaterally symmetrical mechanical arms. The lower ends of the mechanical arms on the left and right sides are rotatably connected with lifting devices located in the box body auxiliary cavities. The upper ends of the mechanical arms on the left and right sides are connected with a snow removing mechanical arms. The snow removing mechanical arms on the left and right sides are in sliding connection to the upper ends of the two sides of the rocker arm device respectively. The invention provides a cable patrol robot capable of workingnormally on a snowy cable. The cable patrol robot can realize the independent line spanning and cable detection functions, and has a relatively efficient continuous snow removal function.
