[0002] A steel truss bridge is a bridge structure system that forms an integral load-bearing structure through the rigid connection between beams and piers. Most existing steel truss bridges are temporarily erected at predetermined target locations to suit scenarios that require rapid construction or adaptation to special terrain.

[0003] When a steel truss bridge encounters safety hazards such as partial fractures or collapses, or when special circumstances such as bridge maintenance or other natural disasters require the bridge to be temporarily closed to traffic, emergency devices need to be placed on the bridge deck to provide emergency protection for pedestrians and vehicles, thereby improving the safety of crossing the steel truss bridge.

[0004] However, existing emergency devices still have the following defects and shortcomings: 1) Existing emergency devices often rely on temporary construction using signs and foundations, which requires on-site fabrication, is time-consuming and labor-intensive, and has low adaptability.

[0005] 2) Existing emergency devices are often temporarily erected on the top of the bridge deck by signs and foundations, which may be moved by people, posing a safety hazard.

[0006] 3) Existing emergency devices are ineffective in alerting users to severe weather conditions such as rain and night.

[0007] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

[0027] [First Embodiment] like Figure 1-4 The image shown is a steel frame bridge with a liftable emergency device provided in the first embodiment of this utility model, such as... Figure 1As shown, the system includes a steel bridge body 1, which is typically placed between the two banks of a river to provide a crossing for vehicles and pedestrians. The improvement of this embodiment compared to existing technologies lies in the following: emergency devices 2 are respectively installed at the bottom of both sides of the steel bridge body 1. Protective components 3 are fixed to the outside of the emergency devices 2, and the protective components 3 can move up and down synchronously relative to the steel bridge body 1 along with the emergency devices 2. By installing the emergency devices and protective components, the road on the steel bridge body can be quickly closed off through their synchronous up and down movement, intercepting passing vehicles and pedestrians and preventing them from entering the steel bridge body 1. No on-site fabrication is required, and the emergency devices and protective components are respectively raised and lowered in coordination with the steel bridge body, effectively improving adaptability.

[0028] like Figure 2-3 As shown, the emergency device 2 in this embodiment includes an electric telescopic pole 21. The electric telescopic pole 21 is electrically connected to the built-in battery or external power source of the steel bridge body 1. The fixed end of the electric telescopic pole 21 is fixedly connected to the bottom of the steel bridge body 1. A push rod 22 is fixedly connected to the output end of the electric telescopic pole 21. A reinforcing block 27 is fixedly connected between the output end of the electric telescopic pole 21 and the push rod 22 to further improve the connection strength. The output end is located below the fixed end and can move up and down relative to the fixed end. Fences 23 are fixedly connected to the top of both sides of the push rod 22. A top plate 24 is fixedly connected to the top of the fences 23. A plurality of equidistant protrusions 25 are fixedly provided on the top of the top plate 24 to provide a speed bump for pedestrians and vehicles when the top plate 24 is not raised. The steel bridge body 1 Rectangular holes 28 are provided on both sides of the bridge. The fence 23 is located inside the rectangular holes 28 and can slide up and down relative to the rectangular holes 28. The outer edge of the top plate 24 is adapted to the inner wall of the rectangular holes 28. By setting up an emergency device 2, when the steel bridge needs to be temporarily closed to traffic, the electric telescopic pole 21 is activated. The output end of the electric telescopic pole 21 drives the push rod 22 to move closer to the upper part of the steel bridge body 1, so that the push rod 22 pushes the fence 23 to move upward along the inside of the rectangular holes 28. At this time, the fence 23 drives the top plate 24 to move upward synchronously. When the fence 23 rises from the inside of the rectangular holes 28 to the highest position, the part of the fence 23 that is higher than the surface of the steel bridge body 1 closes the road, and the emergency interception of vehicles and pedestrians is carried out, improving traffic safety and the emergency efficiency of the steel bridge body 1.

[0029] Based on this, as a further preferred option, an indicator light 26 is fixedly installed inside the fence 23. The indicator light 26 is electrically connected to the built-in battery or external power source of the steel frame bridge body 1, which can effectively improve the warning effect of the emergency device in severe weather such as rain and night.

[0030] like Figure 3-4As shown, the protective component 3 in this embodiment includes a blocking post 32. The blocking post 32 is fixedly connected to the outside of the push rod 22 via a support rod 31. Circular holes 35 are provided on both sides of the steel frame bridge body 1 and on the outside of the rectangular hole 28. The blocking post 32 is located inside the circular hole 35 and can move up and down relative to the circular hole 35. By setting the protective component 3, when the fence 23 is moving upward, the push rod 22 drives the blocking post 32 to move upward synchronously along the inside of the circular hole 35 via the support rod 31. When the fence 23 rises to the highest position inside the rectangular hole 28, the blocking post 32 completely moves out of the circular hole 35 and is placed on the outside of the fence 23, close to the vehicles and pedestrians, to intercept the vehicles and pedestrians and prevent them from directly colliding with the fence 23, thereby protecting the fence 23, reducing direct collisions with the fence 23, and improving the safety of the emergency device 2.

[0031] As a further preferred embodiment, a rubber pad 33 is fixedly fitted onto the outer edge of the barrier post 32. The rubber pad 33 separates vehicles and pedestrians from the barrier post 32, reducing damage during collisions. Simultaneously, a prismatic reflector 34 is fixedly attached to the top of the barrier post 32, effectively improving the visibility of the protective components in adverse weather conditions such as rain and night. Furthermore, the outer diameters of both the rubber pad 33 and the reflector 34 are smaller than the diameter of the circular hole 35, facilitating their movement within the circular hole 35.

[0032] The specific working process of this embodiment includes: When the steel bridge needs to be temporarily closed to traffic, the electric telescopic pole 21 is activated. The output end of the electric telescopic pole 21 drives the push rod 22 to move upward closer to the steel bridge body 1, so that the push rod 22 pushes the fence 23 to move upward along the inside of the rectangular hole 28. At this time, the fence 23 drives the top plate 24 to move upward synchronously. When the fence 23 rises to the highest position from the inside of the rectangular hole 28, the part of the fence 23 that is above the surface of the steel bridge body 1 closes the road, and the emergency interception of vehicles and pedestrians is carried out. At the same time, the indicator light 26 continuously provides light to remind people of the raising of the fence 23 and the danger warning, thereby achieving the emergency interception of vehicles and pedestrians.

[0033] As the fence 23 moves upward, the push rod 22 drives the blocking post 32 to move synchronously upward along the inside of the circular hole 35 via the support rod 31. When the fence 23 rises to its highest position inside the rectangular hole 28, the blocking post 32 completely moves out of the circular hole 35 and is placed on the outside of the fence 23, close to the vehicles and pedestrians, to intercept the vehicles and pedestrians and prevent them from directly colliding with the fence 23, thereby protecting the fence 23. The diamond-shaped reflective block 34 reflects light under the illumination effect provided by the indicator light 26, further improving the warning effect of the protective components in inclement weather such as rain and night.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
