The side plate connecting rods are located above the supporting back plate to fix the two oppositely arranged side plates. The upward extension end of the supporting side plate is curved inwards. The longitudinal sides of the grid unit are fixedly connected to the lower part of the corresponding supporting side plate. The longitudinal ends of the anti-climb rod are fixedly connected to the upward extension end of the corresponding supporting side plate. The grid unit is tensioned on the corresponding supporting side plate.

[0009] Furthermore, a sliding rotary cylinder is fitted onto the side plate connecting rod.

[0010] Furthermore, the grid unit includes grid horizontal bars and grid vertical bars. Multiple grid vertical bars are arranged at intervals along the longitudinal direction and are fixedly connected by grid horizontal bars.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides an anti-climbing railing device 100, including support columns 10, grid units 20, mesh units 30, and anti-climbing units 40. At least two support columns 10 are arranged longitudinally at intervals. The grid units 20, mesh units, and anti-climbing units 40 are respectively arranged between two adjacent support columns 10. The grid units 20 are arranged at the bottom of the support columns 10, the anti-climbing units 40 are arranged at the top of the support columns, and the mesh units are arranged between the grid units 20 and the anti-climbing units 40. The anti-climbing unit 40 includes an anti-climbing rod 41 arranged longitudinally between the two support columns 10. A first rotating ring 42 is sleeved on the anti-climbing rod 41, and the first rotating ring 42 is rotatably arranged.

[0032] The anti-climb railing device 100 provided by this utility model includes a support pier 10, a grid unit 20, a mesh unit 30, and an anti-climb unit 40. The support pier 10 serves as the installation base for fixing to both sides of the bridge in the lateral direction. The grid unit 20 is installed between two support piers 10 for protection from below, and the mesh unit 30 is installed between two piers for protection from the middle and above. Meanwhile, the anti-climb unit 40 is arranged at the top and includes an anti-climb rod 41 arranged longitudinally between two support piers 10. A first rotating ring 42 is sleeved on the anti-climb rod 41. The first rotating ring 42 is rotatably set and is used to unload force and enhance the climbing obstacle, thus solving the technical problem of insufficient anti-climb design in existing bridge railings, resulting in a low level of physical isolation protection.

[0033] Furthermore, the upwardly extending end of the support column 10 is arranged in an inwardly curved arc. In this invention, on the one hand, the curved end increases the difficulty of climbing. Even if the climber passes through the lower grid unit 20, the difficulty of gripping and leveraging the top of the curved support column 10 is significantly increased, further preventing the climbing behavior; on the other hand, the curved structure increases the aerodynamic performance of the entire device to a certain extent.

[0034] Furthermore, the anti-climbing railing device 100 provided by this utility model innovatively integrates supporting pillars 10, grid units 20, mesh units 30, and anti-climbing units 40, forming a comprehensive protection system. The supporting pillars 10 are arranged longitudinally at intervals, providing a stable foundation for the entire device. The grid units 20 are arranged at the bottom of the supporting pillars 10, effectively blocking climbing from below and forming the first line of defense. The anti-climbing units 40 are arranged at the top of the supporting pillars 10, wherein the anti-climbing rod 41 connects two supporting pillars 10 longitudinally, and the fitted first rotating ring 42 is rotatable. When someone attempts to climb, the rotation of the rotating ring effectively dissipates the climber's force, making it difficult to continue climbing, thereby greatly enhancing the climbing obstacle and improving the protection level. The grid unit 30 is positioned in the middle, further enhancing the protective strength. It works in conjunction with the grid unit 20 and the anti-climb unit 40 to achieve all-round protection from bottom to top, effectively solving the problem of insufficient anti-climb design of existing bridge railings, improving the reliability of physical isolation, reducing safety hazards, and ensuring the safety of the bridge area.

[0035] Furthermore, the supporting pier 10 includes a foundation installation section and a top extension section. The top extension section is fixedly mounted on the foundation installation section. It also includes a base 11, supporting side plates 12, supporting back plates 13, and side plate connecting rods 14. The supporting back plate 13 is fixedly mounted on the base 11. Two supporting side plates 12 are longitudinally opposite to each other on the base 11 and are fixedly connected by the supporting back plate 13. The supporting back plate 13 and the two supporting side plates 12 enclose an inner operating opening. The supporting pier 10 includes a base 11, supporting side plates 12, supporting back plates 13, and side plate connecting rods 14. The supporting back plate 13 is fixedly mounted on the base 11. Support side plates 12 are longitudinally mounted on the base 11 and fixedly connected by a support back plate 13. The support back plate 13 and the two support side plates 12 enclose an inner operating opening. A side plate connecting rod 14 is located above the support back plate 13 to fix the two oppositely arranged side plates. The upwardly extending ends of the support side plates 12 are curved inwards. The longitudinal sides of the grid unit 20 are fixedly connected to the lower part of the corresponding support side plate 12. The longitudinal ends of the anti-climb rod 41 are fixedly connected to the upwardly extending ends of the corresponding support side plate 12. The grid unit 30 is tensioned on the corresponding support side plate 12. In this utility model, the support pier 10 consists of a foundation installation section and a top heightening section. The grid unit 20 is arranged on the foundation installation section, and the grid unit 30 and the anti-climb unit 40 are arranged on the top heightening section. Understandably, by arranging the inner operating opening, the installation, adjustment, and maintenance of each component are facilitated.

[0036] Furthermore, a sliding rotary cylinder is fitted onto the side plate connecting rod 14. The presence of the sliding rotary cylinder allows for a certain degree of rotation or sliding when subjected to external impact or when a climber attempts to climb. This movement can effectively consume the climber's strength, reduce their success rate in climbing, and enhance the device's anti-climbing capability.

[0037] Furthermore, the grid unit 20 includes grid horizontal bars and grid vertical bars. Multiple grid vertical bars are arranged longitudinally at intervals and fixedly connected by the grid horizontal bars. A first mounting hole is provided on the bottom side of the supporting pier 10, and the grid horizontal bars are inserted between two supporting piers 10 through the first mounting hole. In this invention, the grid unit 20 is composed of grid horizontal bars and grid vertical bars. Multiple grid vertical bars are arranged longitudinally at intervals and fixedly connected by the grid horizontal bars, forming a stable and robust protective grid. The first mounting hole on the bottom side of the supporting pier 10 provides a convenient way to install the grid horizontal bars. The insertion method allows the grid unit 20 to be quickly and securely installed between two supporting piers 10, improving installation efficiency and facilitating subsequent disassembly and replacement. The grid unit 20 provides effective safety protection for the area beneath the bridge.

[0038] Furthermore, the grid crossbar includes a bottom connecting rod, a lower handrail, and an upper handrail arranged sequentially along the height direction, with the lower and upper handrails located inside the grid vertical bars. The grid vertical bars are curved members, with the lower part curving inward and the upper part recessed outward. The inner side of the support side plate 12 has a handrail lug, and the lower handrail is inserted into the handrail lug. The bottom connecting rod provides basic connecting support, enhancing the connection strength between the grid unit 20 and the support column 10. The lower and upper handrails not only serve as connecting components but also provide convenient support for pedestrians, improving the comfort and safety of passage. Simultaneously, placing the lower and upper handrails inside the grid vertical bars avoids potential safety hazards such as hooking from exposed handrails. Furthermore, the curved member design of the grid vertical bars, with the lower part curving inward and the upper part recessed outward, further enhances the anti-climbing effect.

[0039] Furthermore, the grid unit 30 includes protective steel wires 31 arranged sequentially along the height direction, with the protective steel wires 31 tensioned between two supporting columns 10; the spacing between two adjacent protective steel wires 31 gradually increases along the upward direction of height. Understandably, the grid unit 30, composed of protective steel wires 31 arranged sequentially along the height direction and tensioned between two supporting columns 10, forms a tight and robust protective mesh. This design of the protective steel wires 31 effectively prevents personnel from climbing from the middle and above, forming a comprehensive protection system together with the grid unit 20 and the anti-climb unit 40; the mesh size of the grid unit 30 can be adjusted according to actual protection needs to meet safety requirements in different scenarios, enhancing the adaptability and practicality of the entire guardrail device.

[0040] Understandably, in this invention, the first rotating rings 42 are densely arranged longitudinally; the inward-sloping anti-climbing railing device 100 of this invention has an overall permeability of over 85%, significantly altering the aerodynamic shape of the structure. In this invention, the anti-climbing rod can be either steel wire or steel rod.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
