[0012] Through the cooperation between the large limit block, the medium limit block and the small limit block, different movable rods can be limited and slid, so that the practicality of the ladder can be improved.

[0013] As a preferred implementation, the outer wall of the positioning ring fits into the ground surface of the outer wall of the wellhead.

[0014] As a preferred embodiment, the second movable rod is slidably mounted on the inner wall of the movable groove, the third movable rod is slidably mounted on the inner wall of the sliding groove, and the fourth movable rod is slidably mounted on the inner wall of the mounting groove.

[0015] Through the cooperation between the first movable rod, the second movable rod, the third movable rod and the fourth movable rod, the ladder can be easily stored, thereby further improving the practicality of the ladder.

[0016] Compared with the prior art, the utility model provides a ladder for municipal road inspection wells, which has at least the following beneficial effects:

[0017] (1) Through the cooperation between the positioning ring, the mounting block, the first movable rod, the second movable rod, the third movable rod and the fourth movable rod, the ladder can be retracted and extended, and is easy to store. The positioning ring can also be used to position the ladder on the surface of the wellhead, thereby eliminating the need to install the ladder on the inner wall of the wellhead, thereby reducing construction costs.
