[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-3 As shown, the present invention provides a detachable ladder, including a ladder body 1, a guardrail assembly 12 detachably mounted on the ladder body 1, and a protective structure 17 mounted on the top of the ladder body 1. Several footrest beams 5 are spaced apart on the ladder body 1.

[0022] The ladder body 1 comprises a lower ladder 2, a middle ladder 3, and an upper ladder 4, which are detachably connected from bottom to top. Each of the lower ladder 2, middle ladder 3, and upper ladder 4 is equipped with a guardrail mounting position 15. The lower ladder 2 and middle ladder 3, and the middle ladder 3 and upper ladder 4 are fixed together with bolts. This layered, detachable structure allows the ladder to be disassembled into smaller components, minimizing space requirements during transport. The assembled ladder body 1 is installed on the side of the maintenance water tank. Mounting profiles can be pre-welded onto the industrial water tank, and these profiles are connected to the corresponding mounting points on the ladder body 1 using bolts. A protective structure 17 is located at the top of the ladder body 1 to prevent operators from falling. A footrest beam 5 provides a gripping and stepping surface for climbing.

[0023] The footrest crossbeam 5 includes a mounting shaft 6, footrest plates 7 fixed to the mounting shaft 6, and connectors located on both sides of the mounting shaft 6. The connectors are inserted into the ladder body 1. The footrest plates 7 are located on the side of the mounting shaft 6 away from the guardrail assembly 12, and a clearance groove 8 is provided between the footrest plates 7 and the mounting shaft 6, with the clearance groove 8 located in the middle of the mounting shaft 6. Anti-slip stripes 9 are arranged parallel to each other on the footrest plates 7.

[0024] In the above design, the mounting shaft 6 serves two purposes: firstly, it accommodates the footrest 7, and secondly, it provides a gripping surface for climbing. The resulting clearance groove 8 allows for proper gripping. The footrest 7 provides a larger footing area and features anti-slip stripes 9 to prevent slippage due to instability. The footrest 7 is positioned on the side of the mounting shaft 6 furthest from the guardrail assembly 12, ensuring it doesn't obstruct the operator's steps during climbing and prevent tripping.

[0025] The connector includes a bent connecting plate 10. A limit groove 11 is provided on the ladder body. The connecting plate 10 is hooked into the limit groove 11 and connected to the limit groove 11 by bolts. The connection plate 10 and the limit groove 11 cooperate to allow for the installation of the footrest crossbeam. Furthermore, if the footrest crossbeam is damaged, it can be quickly disassembled and replaced, offering greater flexibility in assembly and disassembly compared to welding.

[0026] The guardrail assembly 12 includes several spaced-apart arc-shaped protective strips 13 and connecting strips 14 connecting the arc-shaped protective strips 13. Guardrail mounting positions 15 are equidistantly distributed. Each arc-shaped protective strip 13 has a mounting piece 16 at both ends. The mounting pieces 16 snap into the guardrail mounting positions 15 and are fixed to them with bolts. The mounting pieces 16 are snapped into grooves in the guardrail mounting positions 15 and then fixed with bolts. The equidistant arrangement of the guardrail mounting positions 15 ensures that the arc-shaped protective strips 13 are installed at equal intervals. The connecting strips 14 can be configured to connect the arc-shaped protective strips, increasing the stability of the guardrail assembly 12.

[0027] The protective structure 17 includes two symmetrically arranged semi-circular protective components. Both semi-circular protective components are rotatably connected to the top of the ladder body 1. When the two semi-circular protective components are rotated, they open or close the passage between the guardrail assembly 12 and the ladder body. The semi-circular protective component includes a protective body 18 and a plurality of baffles 19 spaced apart on one side of the protective body 18, with a light-transmitting area 20 formed between two adjacent baffles 19.

[0028] Two semi-circular safety guards are fixed to the edge of the top platform of the ladder via a rotating shaft. When climbing to the top, personnel push open the semi-circular guards to enter the platform, and after leaving, they manually rotate the two semi-circular guards to close the passage. The rotating guards can block the fall passage at the top of the ladder, making it safer than traditional open ladders. The passage can be opened and closed simply by rotating the guards, making it easy to operate. The 20mm light-transmitting zone design ensures protection without affecting the light intake at the top and the interaction of sight between the top and bottom, thus improving climbing safety.

[0029] In this design, the main body of the ladder features a layered, detachable design, allowing it to be disassembled into smaller components, significantly reducing the space required for transportation. The footrest beams are designed with an enlarged surface area to effectively prevent climbers from slipping, while the central groove provides gripping space and avoids obstructing footsteps. The connecting components use hanging plates and limiting grooves, secured with bolts, making the footrest beams easy to assemble and disassemble. A rotating semi-circular safety feature at the top blocks fall paths, significantly improving both safety and practicality.
