[0002] In industries such as power and communications, cable brackets are important components for supporting and fixing cables. Traditional cable brackets are generally made of ordinary metals or galvanized steel.

[0003] Ordinary metal cable supports are prone to deformation at high temperatures, and may even accelerate the spread of fire, especially when cables are on fire. Galvanized steel cable supports, on the other hand, are less resistant to corrosion.

[0004] Therefore, existing cable supports are insufficient to meet the needs of use in complex environments. Utility Model Content

[0014] The material of the carbonized coating includes graphene composite material.

[0015] Optionally, the fire-retardant and anti-corrosion coating may further include a heat-insulating coating.

[0016] The heat insulation coating is applied to the side of the carbonized coating that is away from the flame retardant coating.

[0017] The material of the heat insulation coating includes aerogel composite material.

[0018] Optionally, the base material of the cross brace of the bracket is 304 stainless steel or aluminum alloy.

[0019] Optionally, the cross brace of the support further includes a second end, which is the end of the cross brace of the support that is away from the first end;

[0020] The support cross brace has at least one cross brace square hole, which is located between the first end and the second end.

[0021] Optionally, a folded edge is provided on the second end of the cross brace of the bracket;

[0022] The folded edge is set at a preset angle to the support column.

[0023] Optionally, the support column is provided with a plurality of cross brace mounting holes, the cross brace mounting holes including a first cross brace mounting hole and a second cross brace mounting hole; each of the support cross braces is provided with a first protrusion and a second protrusion at its first end, and each cross brace mounting hole corresponds to one support cross brace;

[0024] For each of the bracket cross braces, the first protrusion of the bracket cross brace passes through the corresponding first cross brace mounting hole, and the second protrusion of the bracket cross brace passes through the corresponding second cross brace mounting hole, so that the bracket cross brace is fastened and fixed to the bracket column.

[0028] The beneficial effects of the cable bracket and cable bracket assembly provided by this utility model are:

[0029] Because the outer surface of the cross braces is coated with a fire-retardant and corrosion-resistant paint, the safety and lifespan of the cable support are improved.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Traditional cable supports are inadequate in terms of fire and corrosion resistance, making them unsuitable for use in complex environments. Traditional cable supports have the following drawbacks:

[0043] 1. Poor fire resistance: Ordinary metal brackets have no fireproof coating and are prone to deformation at high temperatures (fire resistance limit <30 minutes). When cables catch fire, they will accelerate the spread of fire.

[0044] 2. Weak corrosion resistance: Galvanized steel supports will rust in 3-5 years in humid environments (salt spray test ≤480h).

[0045] Based on the above, this specification provides a cable bracket 01 and a cable bracket assembly, which can effectively alleviate the above-mentioned technical problems.

[0046] Please see Figure 1 This embodiment provides a cable bracket 01, which includes a bracket column 10 and a plurality of bracket cross braces 20, each of which includes a first end 21.

[0047] The first end 21 of each support cross brace 20 is fixed on the support column 10, and each support cross brace 20 is arranged sequentially on the support column 10 at a preset interval.

[0048] Each support cross brace 20 has its outer surface coated with fire-retardant and corrosion-resistant paint 22.

[0049] like Figure 1 As shown, a bracket column 10 is equipped with multiple bracket cross braces 20, and the first end 21 of each bracket cross brace 20 is fixed to the bracket column 10. The side of the bracket cross brace 20 that carries the cable is perpendicular to the bracket column 10.

[0050] The outer surface of the cross brace 20 is coated with Figure 2 The fireproof and anti-corrosion coating 22 shown can effectively prevent the external environment from corroding the support cross brace 20, and at the same time, it can slow down the spread of fire and protect the safety of the cable in the event of a fire.

[0051] Optionally, the fire-retardant and corrosion-resistant coating 22 includes a flame-retardant coating layer 221.

[0052] A flame-retardant coating 221 is applied to the substrate 222 of the support cross brace 20. The material of the flame-retardant coating 221 includes aluminum hydroxide flame retardant.

[0053] Aluminum hydroxide flame retardant decomposes endothermically (878 J / g) at 200–350℃, which can lower the surface temperature of materials and slow down the combustion process. Its decomposition produces water vapor, which can dilute the concentration of oxygen and combustible gases, weakening the combustion reaction intensity. In addition, aluminum hydroxide flame retardant can form a dense alumina (Al₂O₃) protective layer, isolating oxygen and inhibiting heat transfer. Simultaneously, aluminum hydroxide flame retardant can catalyze the formation of a char layer on the material surface, preventing flame spread and reducing the release of smoke and toxic gases.

[0054] Therefore, as Figure 2 As shown, a flame-retardant coating 221 can be applied to the substrate 222 of the support cross brace 20, and its components include aluminum hydroxide flame retardant.

[0055] Optionally, the fire-retardant and corrosion-resistant coating 22 may also include a carbonized coating 223.

[0056] The carbonized coating 223 is applied to the side of the flame-retardant coating 221 away from the substrate 222 of the support cross brace 20. The material of the carbonized coating 223 includes graphene composite material.

[0057] Graphene possesses high-temperature resistance (decomposition temperature > 450℃), which can improve the thermal stability of composite materials and delay the degradation of material properties at high temperatures. Furthermore, graphene has an inherent tensile strength of 130 GPa and a Young's modulus of 1.0 TPa. When combined with polymers or metal matrices, it can significantly improve the tensile strength, toughness, and fatigue resistance of materials, making it suitable for high-strength structural materials.

[0058] Therefore, a carbonized layer coating 223, including graphene composite material, can be applied to the flame-retardant coating 221 to increase the high temperature resistance and strength of the support cross brace 20.

[0059] Optionally, the fire-retardant and corrosion-resistant coating 22 may also include a heat-insulating coating 224.

[0060] The heat insulation coating 224 is applied to the side of the carbonized coating 223 that is away from the flame retardant coating 221. The material of the heat insulation coating 224 includes an aerogel composite material.

[0061] Aerogel composites exhibit a porosity of 80%-99.8%, with nanoscale pore sizes (1-100 nm) suppressing air molecule flow and convective heat transfer. Their thermal conductivity is as low as 0.013-0.018 W / (m·K), resulting in superior thermal insulation performance compared to traditional materials at room temperature. Furthermore, by optimizing the porous network structure (such as a shell-like nanocomposite design), thermal insulation stability under extreme environments can be further improved, for example, maintaining structural integrity and low thermal conductivity (17.4 mW / (m·K)) within a temperature range of -196℃ to 1000℃.

[0062] Therefore, a thermal insulation coating 224, including an aerogel composite material, can be applied to the carbonized layer to improve the thermal insulation performance of the support cross brace 20.

[0063] Optionally, the base 222 of the support cross brace 20 is made of 304 stainless steel or aluminum alloy.

[0064] 304 stainless steel and aluminum alloys have good strength and corrosion resistance. Using 304 stainless steel or aluminum alloy as the base material 222 of the cross brace 20 can ensure the structural strength and stability of the cable bracket 01.

[0065] Optionally, the support cross brace 20 also includes a second end 23, which is the end of the support cross brace 20 that is away from the first end 21.

[0066] At least one cross brace square hole 24 is provided on the cross brace 20, and the cross brace square hole 24 is located between the first end 21 and the second end 23.

[0067] like Figure 3As shown, the second end 23 of the bracket cross brace 20 can be the end of the bracket cross brace 20 that is not in contact with the bracket column 10 and is far from the first end 21. At least one cross brace square hole 24 is opened on the side of the bracket cross brace 20 that carries the cable, which not only facilitates the fixing of the cable and cable fittings, but also effectively reduces the weight of the bracket cross brace 20, making it convenient for users to transport, install, and disassemble.

[0068] Optionally, a flange 25 is provided on the second end 23 of the cross brace 20. The flange 25 is set at a preset angle with the support column 10.

[0069] Still with Figure 3 For example, a folded edge 25 at a preset angle to the support column 10 is provided on the second end 23 of the support cross brace 20, which can prevent the cable supported on the support cross brace 20 from slipping off the second end 23 of the support cross brace 20.

[0070] Optionally, the support column 10 is provided with a plurality of cross brace mounting holes 11, including a first cross brace mounting hole 111 and a second cross brace mounting hole 112.

[0071] Each support cross brace 20 has a first protrusion 26 and a second protrusion 27 on its first end 21, and each cross brace mounting hole 11 corresponds to one support cross brace 20.

[0072] For each support cross brace 20, the first protrusion 26 of the support cross brace 20 passes through the corresponding first cross brace mounting hole 111, and the second protrusion 27 of the support cross brace 20 passes through the corresponding second cross brace mounting hole 112, so that the support cross brace 20 is fastened and fixed on the support column 10.

[0073] like Figure 4 As shown, the first protrusion 26 and the second protrusion 27 slide downwards after passing through the first cross brace mounting hole 111 and the second cross brace mounting hole 112, respectively, thus fixing the cross brace 20 to the support column 10. When it is necessary to install, disassemble, or adjust the cross brace 20, since no bolts, nuts, or other means are used to fix the cross brace 20, the user can quickly install, disassemble, and adjust the cross brace 20. This greatly reduces the time required for installing and maintaining the cable bracket 01.

[0074] Optionally, the support column 10 is also provided with a plurality of support column fixing holes 12. The support column fixing holes 12 and the cross brace mounting holes 11 are arranged alternately.

[0075] Please see Figure 4 A bracket column fixing hole 12 is opened between every two sets of cross brace mounting holes 11. This reduces the weight of the bracket column 10, and when it is necessary to install and fix the bracket column 10, a suitable bracket column fixing hole 12 can be selected to fix the bracket column 10.

[0076] Based on the same inventive concept, this utility model provides a cable support assembly, which includes two or more cable supports 01 as described above.

[0077] Regarding the cable bracket assembly, the specific functions and structures of each part have been described in detail in the embodiment of cable bracket 01 provided in this specification, and will not be elaborated here.

[0078] The above-described solutions in the embodiments of this utility model have at least the following beneficial effects:

[0079] Because the outer surface of the cross braces is coated with a fire-retardant and corrosion-resistant paint, the safety and lifespan of the cable support are improved. This allows the cable support provided by this invention to be installed and deployed in high-fire-risk environments such as urban underground utility tunnels and chemical industrial zones.

[0080] 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.
