The maintenance ladder body 2 is installed with the wall 1 through the multiple groups of connecting rods 202 and the fixing blocks 203, thereby improving the stability of the maintenance ladder body 2.

[0036] Working principle: When in use, push the push block 704 upward to drive the locking block 7 and the clamping block 705 to move upward, so that the clamping block 705 moves out of the clamping groove 502, and then rotates to open the movable ladder 5, the movable ladder 5 can be used, and then the maintenance personnel ties the belt 8 to the surface of the body, and the maintenance personnel can climb. During the climbing process, the belt 8 follows the maintenance personnel to rise and fall. When the maintenance personnel climbs to the top of the wall 1, they can hold the first connecting block 602 and move quickly to the top of the wall 1, avoiding the operation of climbing over the parapet 3. After the maintenance is completed, the maintenance personnel can also The user can quickly enter the maintenance ladder body 2 and the guardrail 4 to climb, effectively avoiding the safety hazard caused by climbing over the parapet 3. After the maintenance is completed, the movable ladder 5 is rotated under the action of the rotating shaft 503. The rotating shaft 503 will drive the turntable 501 to rotate during the rotation. When the clamping groove 502 is aligned with the clamping block 705, under the action of the spring 702 and the locking block 7, the clamping block 705 is inserted into the inside of the clamping groove 502, thereby locking the turntable 501 and the rotating shaft 503. At this time, the movable ladder 5 is flipped upward, which can effectively prevent non-professionals from using it.
