The invention discloses an inspection well crawling ladder. The inspection well crawling ladder comprises a crawling ladder main body made of round steel; the crawling ladder main body comprises a foot rest lever, two bended supporting feet, and two connecting rods; each bended supporting foot comprises a bended segment embedded into walls and an exposed straight segment; each straight segment is connected with one end of the foot rest lever via a corresponding connecting rod; the foot rest lever and a bended segment are arranged on the two sides of a corresponding straight segment respectively; a foot rest surface of the foot rest lever is a concave surface with inclination angles ranging from 3 to 5 DEG C from the middle part to the two end parts; the foot rest lever, the connecting rods, and the straight segments are all coated with skid-resistant layers made of corrosion-resistant plastic. Structure optimization is adopted, so that stability and gravity center balance can be maintained easily when the inspection well crawling ladder is used by servicemen, slipping is not easily caused, and powerful guarantee is provided for safe repair operation.
