The invention relates to the technical field of power grid maintaining equipment, in particular to a lightning arrester carrying robot. The lightning arrester carrying robot comprises a moving device,an arm body device and a clamp device which are connected sequentially. The arm body device comprises a lifting mechanism, a horizontal moving mechanism, a rotating mechanism and a telescoping mechanism. The clamp device is installed at the moving end of the telescoping mechanism. A clamp support is connected with the moving end of the telescoping mechanism. The clamp support is provided with a first installing face and a second installing face. The first installing face and the second installing face are provided with clamp tracks arranged in parallel. A first edge claw and a second edge claw can slide in the arrangement direction of the clamp tracks. According to the lightning arrester carrying robot, by means of the moving device, the arm body device and the clamp device can be conveniently moved to the position where a lightning arrester needs to be carried, by means of the arm body device, the clamp device is further moved to the adjusting position, thus the clamp device clamps the lightning arrester, the lightning arrester is fixed and carried, the carrying efficiency of the lightning arrester is improved, labor investment is reduced, and the personal risk in the lightning arrester construction process of workers is reduced.
