[0041] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 , Figure 2 and Figure 3 As shown, the first frame 1 has a frame body 11 and two fasteners 12. The frame body 11 is located at one end of the two wind deflectors 4 away from the second frame 2. The frame body 11 is detachably connected to the second frame 2. The two fasteners 12 are spaced apart along the longitudinal direction of the bridge on the side of the frame body 11 near the side guardrail base 3. One end of each fastener 12 is detachably connected to the frame body 11, and the other end abuts against the inner side of the side guardrail base 3.

The frame body 11 is detachably connected to the side guardrail base 3 through the two fasteners 12 to improve the stability of the windproof fire protection device when working in the external environment.

[0042] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1As shown, two connecting parts 5 are also provided. The two connecting parts 5 are arranged at intervals along the longitudinal direction of the bridge. Each connecting part 5 is provided with a first connecting rod 51, a second connecting rod 52 and at least one connecting bolt 53. One end of the first connecting rod 51 is connected to the frame 11 and the other end extends toward the second frame 2. One end of the second connecting rod 52 is connected to one side of the second frame 2 and the other end of the second connecting rod 52 is provided with a mounting groove 521. The other end of each first connecting rod 51 extends into the corresponding mounting groove 521 and is detachably connected to the second connecting rod 52 by at least one connecting bolt 53. The connecting part 5 of this utility model is formed by a first connecting rod 51, a second connecting rod 52 and at least one connecting bolt 53. One end of the first connecting rod 51 is connected to the frame 11, and one end of the second connecting rod 52 is connected to the second frame 2. The other ends of the first connecting rod 51 and the second connecting rod 52 are provided with threaded through holes. The direction of the threaded through holes is perpendicular to the direction of the first connecting rod 51 and the second connecting rod 52. The other end of the first connecting rod 51 is inserted into the mounting groove 521 at the other end of the second connecting rod 52. The connecting bolt 53 is detachably connected to the first connecting rod 51 and the second connecting rod 52 through the threaded through holes. The two connecting parts are firmly connected and easy to disassemble, which improves the stability of the windproof fire-resistant device.

[0043] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 , Figure 4 and Figure 5 As shown, the second frame 2 is equipped with a hanger 21 and a fire-catching box 22. The hanger 21 is located on the outer side of the side rail base 3 along the transverse direction of the bridge. The fire-catching box 22 is located below the bridge deck. The top outer side of the fire-catching box 22 is connected to the bottom of the hanger 21. The fire-catching box 22 is a box structure with an open top. The hanger 21 and the fire-catching box 22 work together to prevent wind damage and collect sparks generated during welding into the fire-catching box 22, preventing sparks from falling below the bridge and causing a fire. This improves the quality of the weld and reduces the risk of fire accidents.

[0044] As an optional implementation, in one embodiment of the invention, a splash-proof layer is further provided, which is laid inside the fire-receiving box 22. The fire-receiving box 22 of this invention is used to receive sparks that fall during welding. Laying the splash-proof layer inside the fire-receiving box 22 prevents sparks from falling into the box and then splashing out again, further reducing the risk of fire accidents.

[0045] As an optional implementation, in one embodiment of the utility model, the splash-proof layer is made of asbestos cloth, which is a high-temperature resistant material with fireproof and heat insulation properties, ensuring the fireproof performance of the splash-proof layer and further improving the safety of the welding process.

[0046] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, both fasteners 12 are fastening bolts. Each fastening bolt is located on the corresponding side of the frame 11 near the side guardrail base 3. The fastening bolt is threadedly connected to the threaded through hole on the frame 11 and extends to abut against the inner side of the side guardrail base 3. Before welding, the fastening bolts are adjusted to fix the windproof fire-receiving device to the side guardrail base 3 to prevent it from falling off in the wind. After one stroke of welding is completed, the fastening bolts are loosened and the device is moved to the next stroke. This ensures the stability of the windproof fire-receiving device while facilitating movement and improving welding efficiency.
