[0002] Power towers are trapezoidal or triangular tower-shaped structures with steel frames. They are mostly built near power plants and substations in the field. They are important facilities for the power sector, providing overhead power lines and serving as protection and support. The design, manufacture, installation, maintenance, and quality inspection of power towers are important guarantees for the operation and development of modern power systems.

[0003] Power tower ladders are mainly used to facilitate workers going up and down power towers. Ladders are divided into integrated ladders and combined folding ladders. Combined folding ladders are generally stored by folding or pulling out, and can be unfolded for use when needed.

[0004] Existing modular folding ladders, in order to facilitate storage and folding, generally consist of a large square bar enclosing a smaller square bar. If the ladder is too long, it will affect the overall strength and increase safety hazards.

[0005] Therefore, it is necessary to provide a convenient folding modular ladder for power towers to solve the above-mentioned technical problems. Utility Model Content

The slide groove and slide opening are connected. The docking assembly can fix the ladders at both ends after they are unfolded, preventing the two ladders from folding after unfolding. The docking block and the limiting assembly dock with each other.

[0010] Preferably, the rotating assembly includes a rotating frame, a limiting structure, and a stabilizing frame, wherein the limiting structure passes through the rotating frame and the stabilizing frame;

[0011] The limiting structure has threaded blocks at both ends, which serve to limit the movement.

[0020] This invention provides a convenient folding modular ladder for power towers. To improve the strength and facilitate storage, the ladder is assembled using a pull-out first and second ladder. Each first or second ladder consists of a pull-out outer frame and an inner frame. The first and second ladders are assembled using rotating components and connecting frames. When not in use, they are folded together for easy storage. When needed, the first and second ladders are unfolded, and the connection is secured using a docking component. The inner frame is then pulled out from inside the outer frame. By using the limiting components for fixation, a complete ladder can be assembled. The ladder can be composed of multiple sections, and the connection points are only connected by rotating components and connecting frames, which ensures the stability of the connection. When the ladder needs to be stored, simply put the inner frame of each ladder section into the inner frame of the outer frame, and then manually remove the connecting components.

The outer surface of the inner frame 103 is provided with a docking assembly 7. The sliding structure 102 includes a support 1021 and a docking block 1022. The support 1021 is located at the bottom of the inner frame 103, and the docking block 1022 is located at the top of the support 1021 near both ends.

[0031] The rotating component 3 installs two connecting frames 2 at the adjacent ends of the first ladder 1 and the second ladder 4, thereby enabling the first ladder 1 and the second ladder 4 to be folded and stored. The slide groove 105 and the slide opening 104 are connected. The docking component 7 can fix the ladders after they are unfolded, preventing the two ladders from being folded after unfolding. The docking block 1022 and the limiting component 5 dock with each other. When the docking block 1022 is inserted into the inside of the limiting component 5, the docking block 1022 can slide inside the slide opening 104, which can limit the range of vertical movement of the inner frame 103.

[0032] The rotating assembly 3 includes a rotating frame 301, a limiting structure 302, and a stabilizing frame 303, wherein the limiting structure 302 passes through the rotating frame 301 and the stabilizing frame 303.

[0040] The limiting component 5 includes a docking component 501, a limiting component 502, and a spring 503, wherein the spring 503 is used to mount the limiting component 502 on one side of the docking component 501.

[0041] The limiting component 502 penetrates the docking component 501 and is inserted into the interior of the east docking block 1022 to fix the unfolded ladder and prevent the inner frame 103 from sliding into the interior of the outer frame 101.

[0042] The working principle of the convenient folding ladder for power towers provided by this utility model is as follows:

[0043] A foldable ladder is assembled by using a pull-out first ladder 1 and a second ladder 4. Each first ladder 1 or second ladder 4 is composed of an outer frame 101 and an inner frame 103 that can be pulled out. The first ladder 1 and the second ladder 4 are assembled by rotating component 3 and connecting frame 2. When not in use, they are folded together for easy storage. When needed, the first ladder 1 and the second ladder 4 are unfolded and the connection is fixed by docking component 7. Then, the inner frame 103 of the ladder is pulled out from inside the outer frame 101 and fixed with limiting component 5 to form a complete ladder. The ladder can be composed of multiple sections, and the connection is only connected by rotating component 3 and connecting frame 2 to ensure connection stability. When the ladder needs to be stored, simply put the inner frame 103 of each section into the outside frame 101, and then manually remove the docking component 7. The multiple sections of the ladder can then be folded up for storage by rotating component 3 and connecting frame 2.

[0044] Compared with related technologies, the convenient folding modular ladder for power towers provided by this utility model has the following advantages:

[0045] To improve the strength and facilitate storage of the modular folding ladder, a pull-out first ladder 1 and second ladder 4 are assembled to form a foldable ladder. Each first ladder 1 or second ladder 4 consists of an outer frame 101 and an inner frame 103 that can be pulled out. The first ladder 1 and second ladder 4 are assembled by rotating component 3 and connecting frame 2. When not in use, they are folded together for easy storage. When needed, the first ladder 1 and second ladder 4 are unfolded and the connection is secured by docking component 7.
