Description

Technical Field

[0001] This utility model relates to the field of road and bridge technology, specifically a safety anti-collision structure for roads and bridges. Background Technology

[0002] The main function of road and bridge anti-collision structures is to protect the bridge itself, prevent damage to the bridge from collisions, and minimize injuries to vehicles and people caused by accidents. Existing road and bridge safety anti-collision structures, as described above, provide localized anti-collision protection. If the impact force is large, the localized area can easily be broken through, resulting in poor anti-collision safety performance. Therefore, a road and bridge safety anti-collision structure with higher safety performance is designed to facilitate the transfer of localized impact force to both sides in the event of a collision, while simultaneously allowing support points to automatically extend outward from both sides to further improve anti-collision performance. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a safety anti-collision structure for roads and bridges, which has high safety protection performance. In the event of a collision, it facilitates the transfer of local impact force to both sides, while the two sides automatically extend support points outward to further improve the anti-collision performance.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety anti-collision structure for roads and bridges, comprising a side plate, wherein multiple sets of anti-collision mechanisms are horizontally spaced on the side plate, each set of anti-collision mechanisms includes an anti-collision column, and both sides of the anti-collision column are hinged to sliders that slide horizontally with the side plate via hinge rods. A fixing block connected to the side plate is provided at the middle position of two sliders, and an elastic component is provided between the two sliders and the fixing block. A support mechanism is hinged at the middle position of two adjacent sets of anti-collision mechanisms, and the support mechanism includes an outward push rod, which is hinged to the two sides of the side plate via hinge rods. In the free state, the outward push rod is located on the side of the two adjacent anti-collision columns closer to the side plate.

[0007] Preferably, a horizontal slide rail is fixedly installed on the upright side plate, each slider is horizontally guided and slidably engaged with the horizontal slide rail, and the fixing block is fixedly connected to the horizontal slide rail.

[0008] Preferably, the elastic component includes a spring, and each slider has an embedded groove on one side facing the fixed block, and the two sides of the spring are fixedly connected to the fixed block and the embedded groove, respectively.

[0009] Preferably, the side of the second hinge rod away from the outward push rod is hinged to the side of the first hinge rod near the slider via the second pivot.

[0010] Preferably, a rotating shaft that is rotatably connected to the hinge rod is fixedly mounted on the slider.

[0011] Preferably, multiple positioning seats are fixedly installed on the side of the upright plate away from the anti-collision column.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a safety anti-collision structure for roads and bridges, which has the following beneficial effects:

[0014] This road and bridge safety collision protection structure, through the setting of multiple sets of horizontally spaced collision protection mechanisms, facilitates the transfer of impact force to both sides when a collision occurs with the central collision protection column. The sliding block is moved outward via a hinged rod, causing it to collide with the adjacent sliding block. Simultaneously, the movement of the hinged rod causes the central push-out column to extend outward, increasing the number of support points and further enhancing collision protection performance. This road and bridge safety collision protection structure offers high safety protection performance, effectively transferring localized impact force to both sides during a collision, while simultaneously allowing support points to automatically extend outward from both sides, further improving collision protection performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-5 A safety anti-collision structure for roads and bridges includes a side panel 1. Multiple anti-collision mechanisms are horizontally spaced on the side panel 1. Each anti-collision mechanism includes an anti-collision column 3. Both sides of the anti-collision column 3 are hinged to sliders 6 that slide horizontally with the side panel 1 via hinge rods 9. A fixing block 7, which is fixedly connected to the side panel 1, is provided in the middle of the two sliders 6. An elastic component is provided between the two sliders 6 and the fixing block 7. A support mechanism is hinged in the middle of two adjacent anti-collision mechanisms. The support mechanism includes an outward push rod 4. The outward push rod 4 is hinged to the hinge rods 9 on both sides via hinge rods 11. In the free state, the outward push rod 4 is located on the side of the two adjacent anti-collision columns 3 closer to the side panel 1.

[0024] Specifically, a horizontal slide rail 5 is fixedly installed on the side plate 1. Each slider 6 is horizontally guided and slidably engaged with the horizontal slide rail 5. The fixing block 7 is fixedly connected to the horizontal slide rail 5. The setting of the horizontal slide rail 5 increases the guiding stability of each slider 6.

[0025] Specifically, the elastic component includes a spring 8. Each slider 6 has an embedded groove on one side facing the fixed block 7. The two sides of the spring 8 are fixedly connected to the fixed block 7 and the embedded groove, respectively. By setting the spring 8, when the slider 6 is pushed outward when it hits the anti-collision column 3, the spring 8 is stretched, so the spring 8 has a tendency to pull back towards the middle.

[0026] Specifically, the side of the hinge rod 11 away from the push rod 4 is hinged to the side of the hinge rod 9 near the slider 6 via the pivot 12. The pivot 12 and the hinge position make it easy to position the push rod 4 inside the anti-collision column 3 in a free state.

[0027] Specifically, a rotating shaft 10 is fixedly installed on the slider 6 and is rotatably connected to the hinge rod 9. The setting of the rotating shaft 10 facilitates the hinge connection between the hinge rod 9 and the slider 6.

[0028] Specifically, multiple positioning seats 2 are fixedly installed on the side of the upright side plate 1 away from the anti-collision column 3. The multiple positioning seats 2 facilitate the installation of the upright side plate 1 on one side of the road and bridge.
