[0018] To make the above objects, features and advantages of the present utility model more obvious and understandable, the specific implementation manners of the present utility model will be described in detail below with reference to the drawings in the specification.

[0019] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0021] Furthermore, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0022] Referring to Figure 1-2 , the present utility model provides an anti-collision and fire-proof protection device for a bridge cable structure, including:

[0023] The hanger cable 100 and a plurality of protective sleeves 200, and the protective sleeve 200 is sleeved on the hanger cable 100;

[0024] The protective sleeve 200 includes an anti-collision buffer inner layer 201, a heat insulation and fire-proof layer 202 and an anti-collision buffer outer layer 203. The anti-collision buffer inner layer 201 is arranged on the inner side, the anti-collision buffer outer layer 203 is arranged on the outer side, and the heat insulation and fire-proof layer 202 is arranged between the anti-collision buffer inner layer 201 and the heat insulation and fire-proof layer 202.

[0025] Among them, the anti-collision buffer outer layer 203 is made of a polymer material, and the use of the polymer material makes the anti-collision buffer outer layer 203 have good toughness and energy absorption characteristics.

[0026] Furthermore, the heat insulation and fire-proof layer 202 is filled with a high-temperature resistant ceramic fiber material. The ceramic fiber material is a material with light weight, high temperature resistance, small heat capacity, good heat preservation and insulation performance, good high-temperature heat insulation performance and non-toxicity, which can better improve the fire-proof performance of the device.

[0027] During use, the protective sleeve 200 is sleeved on the hanger cable 100. When a vehicle hits the protection device, the outer polymer material will deform to absorb the impact force, and change the traveling direction of the vehicle through a rolling mechanism, reducing the direct impact on the cable. In the event of a fire, the flame retardant material in the fire-proof layer can isolate high temperature, delay the heat transfer to the internal steel wire, thereby reducing the burning speed and extending the emergency repair time.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
