Maintenance equipment used on power wire tower

The invention belongs to the technical field of wire tower maintenance, and particularly relates to maintenance equipment used on a power wire tower, the maintenance equipment comprises an engineering vehicle, a mechanical arm and a sweeping execution assembly, the sweeping execution assembly is installed on the engineering vehicle through the mechanical arm with multiple degrees of freedom; when the insulator is cleaned, the shape of the bristle mounting plate can ensure that the front surface of the insulator faces one side of the bristle mounting plate, the insulator is half-wrapped by the rotating bristle mounting plate, and the side, facing the bristle mounting plate, of the front surface of the insulator can be cleaned by bristles on the bristle mounting plate; when the other side is cleaned, a first motor is controlled to work, so that a mounting screw drives a cleaning unit to rotate by 180 degrees around the axis of a rotating ring, and the front face of a rotating bristle mounting plate faces the cl
