A high-voltage circuit maintenance ladder is characterized in that a pin boss is fixed on a support; the pin boss and a rotating seat are connected through a rotating pin; an angle of the support and the rotating seat is adjusted by a gravity cone and is locked by a locking screw; an outer conical surface of the lower end of one support body is matched with an inner conical surface of an inner conical hole of the rotating seat or one lower support body for fixing, and the well attached inner conical surface and outer conical surface are automatically locked through matching of an annular lock slot in the outer conical surface and a self-locking pin after the inner conical hole and the outer conical surface are matched and fixed; foldable type pedals capable of being folded to one end of a connector of each support body is fixed on a column surface of the support body; anti-slip glue is glued at the bottom of the support. The high-voltage circuit maintenance ladder is simple in structure, very convenient to manufacture, assemble and use and portable, a tool is not required in assembling and disassembling processes when the ladder is used, the problem about upright climbing and standing of a high-voltage circuit maintenance worker is solved, and the ladder is fast to assemble, safe, reliable and convenient to climb; the ladder is convenient to disassemble, package and transport after use.
