Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a lightweight bulwark ladder. This solves the problems of traditional bulwark ladders, such as difficulty in balancing lightweight and stability, the need for complete disassembly for repair of vulnerable parts, cumbersome operation, high maintenance costs, insufficient stability during use, and inability to guarantee passage safety.

[0004] This utility model also provides a lightweight bulwark ladder as described above, comprising: a left ladder frame column, a connecting frame fixedly connected to the right surface of the left ladder frame column, a right ladder frame column fixedly connected to the right surface of the connecting frame, and support rods embedded inside the left and right ladder frame columns, with a rotating rod threaded to the upper end of the support rods; and a ladder plate, with limit plates fixedly connected to the left and right surfaces of the ladder plate, and an anti-slip pad fixedly connected to the upper surface of the ladder plate. These devices facilitate the formation of a stable main frame, enable quick disassembly and assembly of vulnerable parts, improve stability and ease of maintenance, and ensure safe passage.

[0005] According to the present invention, a lightweight wall ladder is provided with a limiting groove on the right surface of the left ladder column and the left surface of the right ladder column. The limiting plate is located inside the limiting groove. The above device is beneficial for accurately positioning the ladder plate, preventing displacement during use, improving the stability of the ladder body, and simplifying the ladder plate disassembly and assembly process, reducing maintenance difficulty.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-4 This utility model discloses a lightweight bulwark ladder, comprising: a left ladder column 1, a connecting frame 3 fixedly connected to the right surface of the left ladder column 1, a right ladder column 11 fixedly connected to the right surface of the connecting frame 3, support rods 8 embedded inside the left and right ladder columns 1 and 11, positioning holes 10 provided on the upper surfaces of the left and right ladder columns 1 and 11, the lower end of the support rods 8 located inside the positioning holes 10, and a rotating rod 9 threadedly connected to the upper end of the support rods 8, with a threaded hole on the side surface of the rotating rod 9, the upper end of the support rod 8 located inside the threaded hole; and ladder plates 6, with left and right ladder plates 6... A limiting plate 13 is fixedly connected to the surface. A limiting groove 2 is provided on the right surface of the left ladder column 1 and the left surface of the right ladder column 11. The limiting plate 13 is located inside the limiting groove 2. An anti-slip pad 7 is fixedly connected to the upper surface of the ladder plate 6. A positioning groove 12 is provided on the upper surface of the ladder plate 6. The anti-slip pad 7 is located inside the positioning groove 12 and covers the positioning groove 12. The ladder plate 6 and the anti-slip pad 7 are located between the left ladder column 1 and the right ladder column 11. A positioning support column 4 is fixedly connected to the left surface of the left ladder column 1 and the right surface of the right ladder column 11. A hook 5 is rotatably connected to the side surface of the positioning support column 4. Specifically, the left ladder column 1 and the right ladder column 11 serve as the main support structures on both sides of the ladder, bearing the overall load (weight of personnel and materials) and providing an installation foundation for other components such as the ladder plate 6, support rod 8, and positioning support column 4. They disperse the longitudinal pressure and lateral impact force on the ladder through their own rigidity (material strength). The symmetrical distribution on both sides forms a stable frame to ensure the uprightness of the overall ladder structure. They are fixedly connected to the connecting frame 3 (non-core detachable components), but provide detachable slots / holes such as limit slots 2 and positioning holes 10 for vulnerable parts such as the ladder plate 6 and support rod 8, facilitating partial replacement without affecting the main frame. The connecting frame 3 is used to connect the left and right ladder columns, reinforcing the main support structures on both sides. The overall support structure prevents lateral deformation of the ladder (especially to prevent separation of the side columns under load). It uses welding or bolts to rigidly connect the left and right ladder columns, forming a "frame" structure to improve the ladder's torsional rigidity. If bolted connections are used, the connecting frame can be disassembled and replaced separately if damaged, without affecting other core functional components. The ladder plate 6 (including the limiting plate 13, positioning groove 12, and anti-slip pad 7) serves as the load-bearing surface for personnel to step on and is a core component that directly contacts the load. The anti-slip pad 7 enhances friction and prevents slipping in damp environments. During operation, the ladder plate 6 is laterally positioned by the limiting plate 13 embedding into the limiting groove 2 of the left and right ladder columns, preventing slippage when stepped on. Sliding left and right, the positioning groove 12 is used to fix the anti-slip pad 7 to prevent it from shifting due to friction. The ladder plate itself, made of high-strength aluminum alloy and other materials, bears the vertical load and transmits the force to the ladder frame columns on both sides. In terms of disassembly and maintenance, the limiting plate 13 and the limiting groove 2 are in a "plug-in" fit, allowing the ladder plate to be pulled out from the ladder frame column without tools, facilitating quick replacement when a single ladder plate is damaged (without disassembling the entire ladder frame). The anti-slip pad 7 is embedded in the positioning groove 12 and can be directly torn off and replaced with a new pad after wear, resulting in low maintenance costs. The support rod 8 and the rotating rod 9 are used to assist in supporting the ladder body, enhancing the longitudinal stability of the ladder frame column, preventing the ladder frame column from bending and deforming due to excessive load, and the support height can be adjusted to adapt to different loads. In the same scenario, during operation, the lower end of the support rod 8 is inserted into the positioning holes 10 of the left and right ladder columns, and the upper end is connected to the rotating rod 9 through a thread to form a protective mechanism on both sides. The lower end of the support rod 8 and the positioning hole 10 are plug-in type, and can be pulled out directly when disassembling, which is convenient for maintenance or replacement of rods of different lengths to adapt to the scenario. The positioning support column 4 and the hook 5 are used to realize the fixed connection between the ladder body and the wall, and prevent the ladder body from shaking or tipping over during use. During operation, the positioning support column 4 is fixed on the side of the ladder column, providing a rotation fulcrum for the hook 5. The hook 5 can rotate around the positioning support column 4. When in use, the hook is hung on the edge of the wall or the fixed part. The pull force of the hook limits the lateral displacement of the ladder body and ensures that the ladder body is in stable contact with the wall.Positioning hole 10 and limiting slot 2 are both "positioning connectors" used to provide standardized installation positions for support bars and ladder plates, ensuring component assembly accuracy and stability. During operation, the preset hole / slot dimensions restrict the installation freedom of components, preventing loosening or displacement. As fixed structures on the ladder frame column, they are not easily damaged themselves, but they provide a basis for the quick disassembly and replacement of other components (without damaging the ladder frame column itself).

[0016] Working principle: The left ladder frame column 1, the right ladder frame column 11, and the connecting frame 3 form a stable main frame, which disperses longitudinal pressure and lateral impact force through its own rigidity; the ladder plate 6 is positioned by being embedded into the limiting slot 2 by the limiting plate 13, and the anti-slip pad 7 is fixed to the positioning slot 12 to prevent displacement; the support rod 8 is inserted into the positioning hole 10 and threadedly connected to the rotating rod 9 to realize telescopic adjustment and enhance the stability of the ladder frame column; the hook 5 on the positioning support column 4 rotates and hangs on the bulwark to limit the lateral displacement of the ladder body; the positioning hole 10 and the limiting slot 2 accurately position the components, and the vulnerable parts are connected by plug-in and threaded connections to realize quick disassembly and replacement, ensuring stable use and convenient maintenance.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
