However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an anti-collision device for a highway bridge, including an L-shaped plate 1, three limit grooves 2 are opened on the top of the L-shaped plate 1, limit sliders 3 are movably embedded in the inner walls of the three limit grooves 2, a buffer plate 4 is fixedly installed between the tops of the three limit sliders 3, a plurality of buffer springs 5 ​​are fixedly installed on one side of the outer wall of the L-shaped plate 1, and one side of the outer wall of the plurality of buffer springs 5 ​​is fixedly connected to the opposite side of the outer wall of the buffer plate 4, a plurality of dampers 6 are fixedly installed on one side of the outer wall of the L-shaped plate 1, and one side of the outer wall of the plurality of dampers 6 is fixedly connected to the opposite side of the outer wall of the buffer plate 4, and the outer walls of the plurality of dampers 6 are connected to the inside of the plurality of buffer springs 5, and five anti-collision airbags 7 are fixedly installed on one side of the outer wall of the buffer plate 4.

[0024] The effect achieved by the entire embodiment 1 is that when a vehicle collides on a road or a bridge, the five anti-collision airbags 7 installed on one side of the buffer plate 4 can initially reduce the impact force of the collision and achieve a buffering effect. Since multiple buffer springs 5 ​​and multiple dampers 6 are installed between the buffer plate 4 and the L-shaped plate 1, each buffer spring 5 is provided with a damper 6 inside, and then three limit grooves 2 are opened on the top of the L-shaped plate 1, and the three limit sliders 3 fixedly installed at the bottom of the buffer plate 4 are movably embedded in the three limit grooves 2, which further reduces the force of the vehicle's collision with the buffer plate 4 and reduces the degree of damage to the highway bridge, thereby protecting the structural safety of the bridge and further improving the use effect of the highway bridge anti-collision device.

[0025] Embodiment 2, as Figure 2-Figure 4As shown, the back side of the L-shaped plate 1 is in contact with a back plate 8, and two strip blocks 9 are fixedly installed on one side of the outer wall of the back plate 8, and strip holes 10 are provided on the tops of the two strip blocks 9, and two mounting blocks 11 are fixedly installed on the outer wall of the L-shaped plate 1, and one side of the outer wall of the two mounting blocks 11 is in contact with the opposite side of the outer wall of the back plate 8, one side of the outer wall of the two mounting blocks 11 is provided with strip sleeve holes 12, and the outer walls of the two strip blocks 9 are movably inserted into the inside of the two strip sleeve holes 12, the inner walls of the two strip holes 10 are movably inserted with T-shaped inserts 13, and one side of the outer walls of the two T-shaped inserts 13 are movably inserted with fixing bolts 14, and the outer walls of the two fixing bolts 14 are threadedly connected to the inside of the two mounting blocks 11.

[0026] The effect achieved by the entire embodiment 2 is that the back plate 8 is fixedly installed at a suitable position on the highway bridge, and then two strip blocks 9 are installed on the back plate 8, and strip holes 10 are opened on the two strip blocks 9. Next, mounting blocks 11 are installed on both sides of the L-shaped plate 1, and strip holes 12 are opened on the two mounting blocks 11. Since the L-shaped plate 1 can be sleeved on the two strip blocks 9 installed on the back plate 8 through the two mounting blocks 11 and the two strip holes 12, and when the two strip blocks 9 are completely inside the two strip holes 12, the two T-shaped strips are inserted. 13 is inserted into the two strip holes 10 at the same time, at this time, the bottoms of the two T-shaped inserts 13 are in contact with the tops of the two mounting blocks 11, and then the two fixing bolts 14 pass through the two T-shaped inserts 13 and are threadedly connected to the inside of the two mounting blocks 11 at the same time, so that the two T-shaped inserts 13 are limited in the two strip holes 10, and the two mounting blocks 11 and the L-shaped plate 1 are also limited and fixed on the back plate 8. The installation process is simple. When the anti-collision device is damaged, it is convenient to disassemble and inspect or repair it, thereby improving the service life and use effect of the anti-collision device.

[0027] Working principle: First, the back plate 8 is installed at a suitable position on the highway bridge. When a vehicle collides with the highway bridge, the five anti-collision airbags 7 installed on one side of the outer wall of the buffer plate 4 can initially reduce the force of the collision. Secondly, the three limit sliders 3 installed at the bottom of the buffer plate 4 are movably embedded in the three limit grooves 2, and then a plurality of buffer springs 5 ​​and a plurality of dampers 6 are installed between the buffer plate 4 and the L-shaped plate 1. In cooperation with the three limit sliders 3 and the three limit grooves 2, the impact force caused by the collision of the vehicle is further reduced, part of the energy can be absorbed, and the impact on the highway bridge is reduced, thereby reducing the degree of damage to the highway bridge. When the anti-collision device is damaged and needs to be repaired, since the L-shaped plate 1 is directly mounted on the two strip blocks 9 through the two mounting blocks 11 and the two strip holes 12, and then the two T-shaped inserts 13 are simultaneously inserted into the strip holes 10, and under the action of the two fixing bolts 14, the L-shaped plate 1 and the anti-collision device can be limited and fixed on the back plate 8, so as to facilitate the disassembly and assembly and maintenance thereof, thereby improving the service life and use effect of the anti-collision device. In general, the anti-collision device can improve the safety of highway bridges, protect the lives and property safety of traffic participants, reduce the occurrence of traffic accidents, and thus improve the use effect of the anti-collision device of the highway bridge.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
