[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figures 1-5, this embodiment provides a new type of single-pile climbing ladder, which includes a plurality of climbing units 100 stacked upward in sequence. A single pile is provided at the bottom of the lowermost climbing unit 100. The climbing unit 100 includes four columns 1, at least two platform frames 2 that connect the four columns 1 and are rectangular, and a ladder 3 provided between two adjacent platform frames 2. A beam-column 21 is provided on the platform frame 2. Among them, the platform frame 2 is enclosed by H-shaped steel. Both ends of the beam-column 21 are clamped into the grooves of the H-shaped steel. One side of the beam-column 21 and one side of the platform frame 2 are connected by a flat plate to form a walking platform 22. The ladder 3 is arranged on the other side of the beam-column 21. The ladder 3 includes two parallel side plates 31 and pedals 32 arranged between the two side plates 31. U-shaped grooves 311 are respectively arranged at both ends of the side plate 31. The side plate 31 is clamped and welded to the beam-column 21 through the U-shaped groove 311. During installation, the ladder 3 can be first fixed and clamped on the beam-column 21 through the self-provided U-shaped groove 311, and then welded and fixed between the U-shaped groove 311 and the beam-column 21. This fixing method not only simplifies the installation steps, but also increases the welding area between the ladder 3 and the beam-column 21, thereby providing the connection strength and stability between the two. Compared with the traditional welding fixing method, the present utility model avoids the cumbersome steps of pre-fixing and improves work efficiency; compared with bolt connection, it does not require regular maintenance and inspection, reduces the maintenance cost, and reduces the safety hazards caused by loosening.

[0025] In this embodiment, to enhance the safety performance of the climbing ladder, prevent the user from being injured due to accidental fall during use, and ensure the life safety of the user, a guardrail 9 is provided around the walking platform 22 of the platform frame 2, and guardrails 33 are provided on both sides of the ladder 3.

[0026] In this embodiment, connecting plates 7 are respectively provided at both ends of the four columns 1 of the climbing unit 100, and connection holes 71 are provided on the connecting plates 7. At least three connection holes 71 are provided on each connecting plate 7. Except for the uppermost climbing unit 100, horizontal cross-section L-shaped installation guide plates 8 are provided at the tops of two diagonally arranged columns 1 of other climbing units 100. The upper half of the installation guide plate 8 is inclined outward. The structural design and installation position design of the installation guide plate 8 enable the upper climbing unit 100 to smoothly slide along the installation guide plate 8 and be fixed on the lower climbing unit 100 when the climbing units 100 are stacked. Then, the two stacked climbing units 100 are fixedly connected by bolts passing through the connection holes 71 and nuts, thereby improving the installation efficiency and reducing the production cost.

[0027] In this embodiment, in order to improve the stability and load-bearing capacity of the entire step ladder, struts 4 distributed in a V-shape are provided between the two side edges of two adjacent platform frames 2. This structural design enables the step ladder to maintain a stable structural state when bearing heavy objects or being used by multiple people simultaneously, without deformation or shaking.
