[0027] like Figure 1 As shown, this embodiment provides a railway catenary steel support conversion base, including a lower mounting plate 3, an upper mounting plate 2, a supporting main component 4, a lower mounting plate rib 6, an upper mounting plate rib 5, and a support column 1.

At least two lower mounting plates 3 are provided, and the two lower mounting plates 3 are respectively installed on a reinforced concrete structural base plate 8, the reinforced concrete structural base plate 8 being designated C45. Figure 5As shown, the upper mounting plate 2 has mounting holes corresponding to the bolt holes of the support column 1 base. The upper mounting plate 2 is 30 mm thick, and at least two are provided.

The supporting main body component 4 is disposed between the lower mounting plate 3 and the upper mounting plate 2, and the supporting main body component 4 is welded to both the lower mounting plate 3 and the upper mounting plate 2. The lower mounting plate rib 6 is 16 mm thick, and at least two sets are provided. The two sets of lower mounting plate rib 6 are respectively disposed on both sides of the supporting main body component 4. One end of the two sets of lower mounting plate rib 6 is welded to the supporting main body component 4, and the other end is welded to the lower mounting plate 3. The upper mounting plate rib 5 is 12 mm thick, and at least two sets are provided. The two sets of upper mounting plate rib 5 are respectively disposed on both sides of the supporting main body component 4. One end of the two sets of upper mounting plate rib 5 is welded to the supporting main body component 4, and the other end is welded to the upper mounting plate 2. The upper mounting plate rib 5 and the lower mounting plate rib 6 are staggered. Bolt holes are provided on the base of the support column 1, and the base of the support column 1 is connected to the upper mounting plate 2. Optionally, the lower mounting plate 3 is connected to the structural base plate via chemical anchors 7, the mechanical performance grade of the chemical anchors 7 being not less than 8.8. In this embodiment, the material of each component is not less than Q355B, and hot-dip galvanizing is used for corrosion protection. In this embodiment, all welds are continuous and closed, and the weld thickness is not less than 12 mm and not less than the smaller thickness of the welded component.

[0028] like Figure 2 As shown, the lower mounting plate 3 is horizontally arranged along the length of the support structure. In this embodiment, the mounting holes on the lower mounting plate 3 are spaced 220 mm, 220 mm, and 360 mm apart from the outside to the inside along the length of the mounting plate, and spaced 460 mm apart along the width of the lower mounting plate 3. The upper mounting plate 2 is arranged along the width of the support structure.

[0029] like Figure 3 As shown, the main support component 4 is a rectangular steel tube with dimensions of 320 mm × 400 mm and a thickness of 16 mm.

[0030] like Figure 4 As shown, the lower mounting plate 3 has 8 mounting holes, and the spacing of each mounting hole corresponds to the concrete structure.

[0031] like Figure 6As shown, the lower mounting plate rib 6 is divided into a first support portion 601 and a first connecting portion 602, with the first support portion 601 being L-shaped. One side of the lower mounting plate rib 6 is fitted and connected to the lower mounting plate 3, and the other side is fitted and connected to the supporting main body component 4. One end of the first connecting portion 602 is connected to the upper end of the first support portion 601, and the other end is connected to the lower end of the first support portion 601.

[0032] like Figure 7 As shown, the upper mounting plate rib 5 is divided into a second support portion 501 and a second connecting portion 502, with the second support portion 501 being L-shaped. One side of the upper mounting plate rib 5 is fitted and connected to the upper mounting plate 2, and the other side is fitted and connected to the supporting main body component 4. One end of the second connecting portion 502 is connected to the upper end of the second support portion 501, and the other end is connected to the lower end of the second support portion 501.

[0033] The mounting holes on the lower mounting plate 3 are arranged at intervals of 220 mm, 220 mm, and 360 mm from the outside to the inside along the length direction of the mounting plate, and at intervals of 460 mm along the width direction of the lower mounting plate 3.

[0034] It is understandable that the issue of the spacing between the mounting holes in the mounting plate under the conversion base was resolved by increasing the spacing between the mounting holes. This solution addresses the requirement in the "Technical Specification for Post-Anchoring of Concrete Structures" (JGJ 145-2013) that the spacing between post-installed chemical anchors must be 6 times the outer diameter of the anchor.

[0035] The upper mounting plate 2 is provided with mounting holes corresponding to the bolt holes of the support column 1 base, and the lower mounting plate 3 is provided with mounting holes matching the chemical anchor 7.

[0036] Understandably, this design ensures a precise and secure connection between the support column and the conversion base. The correspondence between the mounting holes on the upper mounting plate 2 and the bolt holes on the support column base guarantees the verticality and stability of the overhead contact line steel support column, while the matching of the mounting holes on the lower mounting plate 3 and the chemical anchors 7 provides a solid foundation for the entire structure. This precise hole matching not only simplifies the installation process and speeds up the installation, but also improves the adaptability of the conversion base to different support column and anchor types, making it suitable for various installation environments. Furthermore, this design enhances the safety of the entire structure, reduces the risk of structural failure due to improper installation, and makes disassembly and reinstallation more convenient and faster when maintenance or replacement of the support column is required. This improves the installation efficiency, stability, and safety of the railway overhead contact line steel support conversion base, while also facilitating subsequent maintenance and adjustment work.

[0037] In this embodiment, the material of each component is no less than Q355B, and hot-dip galvanizing is used for corrosion protection. In this embodiment, all welds are continuous and closed, and the weld thickness is no less than 12 mm and no less than the minimum thickness of the welded component.

[0038] It is understandable that all components are made of materials no lower than Q355B, ensuring high structural strength and impact resistance, suitable for long-term bearing of heavy mechanical loads. Hot-dip galvanizing effectively prevents corrosion caused by environmental factors, significantly extending service life. The continuous closed design of all welds enhances the overall structural stability and avoids structural weaknesses caused by poor welding. Specific weld thickness specifications ensure weld uniformity and strength, preventing the risk of structural failure due to insufficient welding. These measures collectively improve the safety and reliability of the entire railway catenary steel support conversion base, enabling stable operation under various environmental conditions, thereby ensuring the safety of railway transportation.

[0039] The upper mounting plate rib 5 and the lower mounting plate rib 6 are arranged alternately.

[0040] Understandably, this arrangement effectively enhances the structure's stability and load-bearing capacity, while also improving the overall rigidity and deformation resistance of the transfer base. This design not only simplifies the post-installation of chemical anchors 7 and the tightening of nuts, but also facilitates adaptive adjustments to the positions and pre-drilled holes of the upper mounting plate 2 and lower mounting plate 3, thereby improving installation convenience and adjustment flexibility. Furthermore, the staggered ribs help distribute the load more evenly, reducing stress concentration and extending the service life of the transfer base. This design allows the transfer base to adapt to various working conditions, such as existing bridge piers and existing frames, improving its applicability and reliability in different environments and ensuring the stability and safety of the railway catenary system.
