The invention relates to a lead lifting device for a high-tension line tower grounding line, and provides the lead lifting device, being simple in structure, labor-saving in operation, and convenient to operate, for the high-tension line tower grounding line. The lead lifting device adopts the structure that a U-shaped bracket is arranged on a tower body cement base; two supporting legs of the U-shaped bracket face downwards and are used as bearing components; one end of a horizontal rod is fixedly arranged on the U-shaped bracket; the other end of the horizontal rod is movably arranged on a stand column; the stand column is vertically arranged on the ground; the horizontal rod and the stand column are perpendicular to each other; the horizontal rod is provided with a screw hole meshed with a screw rod in the vertical direction; the screw rod corresponds to the screw hole, is vertically arranged on the horizontal rod, and can move up and down along the horizontal rod; a loose joint ring is arranged at the lower part of the screw rod; the upper end of a hook can be hooked in the loose joint ring; a clamp head is arranged at the lower part of the hook. The lead lifting device can be widely applied to the field of power maintenance.
