[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A steel pipe pile ladder comprises a supporting riser 1 and a protective arc plate 4. There are two supporting risers 1 in total. A horizontal pedal 2 is fixedly arranged equidistantly along the vertical direction between the two supporting risers 1. Protective arc plates 4 are fixedly arranged equidistantly along the vertical direction on the top side of the supporting riser 1. Vertical rods 5 are fixedly arranged equidistantly along the vertical direction on the bottom of multiple groups of protective arc plates 4. A movable hanging assembly for hanging safety ropes and safety buckles is arranged on the outer wall of the supporting riser 1. A bottom seat 3 is fixedly arranged at the bottom of the supporting riser 1. Mounting holes 31 are opened at the four corners of the top of the bottom seat 3. The entire ladder can be fixed on a cement base by using expansion bolts.

[0022] Extension rods 6 are fixedly provided at equal intervals along the vertical direction on the opposite sides of the supporting riser 1 on the protective arc plate 4, and multiple groups of short vertical rods 7 are fixedly provided at one end of the extension rods 6 away from the supporting riser 1. A lap plate 8 is commonly fixedly provided between the bottoms of the two groups of short vertical rods 7, and fixing holes 81 are equidistantly provided on the top of the lap plate 8. The movable suspension assembly includes a left half ring 10, a right half ring 11, a fixing bolt 12, a vertical shift ring 14, and a step block 16. Extension rings 101 are fixedly provided at one end of the left half ring 10 and the right half ring 11, and the fixing bolt 12 is screwed into the common thread of the extension ring 101 on the left half ring 10 and the right half ring 11. Avoidance gaps 9 are provided at one end of the left half ring 10 and the right half ring 11 away from the extension ring 101, and the avoidance gaps 9 are used to avoid the horizontal pedals 2 arranged along the vertical direction.

[0023] A hanging hook 13 is vertically fixed on the side of the right half ring 11, and a vertical shoulder 18 is fixedly provided on the outer wall of the supporting riser 1 in the vertical direction. A vertical moving ring 14 is movably inserted into the vertical shoulder 18 in the vertical direction. A rectangular groove 15 is opened on the side of the left half ring 10, and a step block 16 is fixedly provided on the side of the vertical moving ring 14. The step block 16 extends out of the rectangular groove 15 and the rear side is fixedly connected to one end of a connecting spring 17, and the other end of the connecting spring 17 is fixedly connected to the side of the rectangular groove 15. The width of the head of the step block 16 is greater than the width of the rectangular groove 15, and the head of the step block 16 contacts the side wall of the left half ring 10. The vertical shoulder 18 limits the vertical moving ring 14 to move only in the vertical direction and cannot rotate.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] When the connecting spring 17 is at its original length, the avoidance gap 9 is in an interlaced state with the top of the horizontal pedal 2 distributed along the vertical direction, and the mobile suspension assembly cannot move up along the supporting riser 1. The worker connects the safety buckle of the safety rope to the suspension hook 13. When the worker climbs up, the integral structure of the left half ring 10 and the right half ring 11 needs to be twisted. At this time, the connecting spring 17 is compressed, and the avoidance gap 9 is aligned with the top of the horizontal pedal 2 distributed along the vertical direction.

[0026] When a worker accidentally slips from the top of the horizontal pedal 2 and no longer touches the movable suspension assembly, the connecting spring 17 resets, driving the left half ring 10 and the right half ring 11 integrated structure to reset, and the avoidance gap 9 and the top of the horizontal pedal 2 distributed in the vertical direction are in a staggered state. When the left half ring 10 and the right half ring 11 integrated structure are pulled down by the falling worker, they will overlap with the nearest horizontal pedal 2 to prevent the worker from continuing to fall.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
