The invention relates to the field of electric power facilities, and especially discloses a telegraph pole climbing ladder. The telegraph pole climbing ladder is formed by connecting a plurality of ladder sections, every ladder section comprises two vertical cylinders, the two vertical cylinders are connected by two connecting posts, and a plurality of pedals are arranged between the two connecting posts; the connecting post at the upper end is provided with at least one clamp; every vertical cylinder is provided a through hole in an up-and-down direction, and a T-shaped connecting rod is every through hole; and an arc-shaped rod is hinged to one of the vertical cylinders of at least two ladder sections, and antiskid thorns are arranged at the inner side of the arc-shaped rod. The plurality of ladder sections are assembled on site by the clamps and the T-shaped connecting rods in order to form an integral body, the height of the ladder can be arbitrarily increased from the lower end, the ladder can be hung on a telegraph pole by the arc-shaped rod to form a temporary ladder, and an operator climbs the ladder to reach the top and operates, so the ladder saves labor, and has a high safety factor.
