[0015] The utility model has at least the following beneficial effects:
[0016] 1. When the buffer plate is hit by a car, the rubber buffer pad on the surface is used for preliminary slight buffering, and then the buffer plate slides backward, and the first compression spring and rubber pad arranged inside are used to buffer and unload the impact force, thereby achieving a preliminary energy absorption effect. At the same time, the impact force brought by the car will also cause an impact on the anti-collision guardrail. When the anti-collision guardrail is subjected to the impact force, the rear buffer support plate will move backward, and the internal rubber pad and the second compression spring will be used to buffer and unload the impact force, thereby achieving a further energy absorption effect, thereby buffering the force unloading when the vehicle loses control protection, and will not cause secondary injury to the people in the car.

DETAILED DESCRIPTION
[0025] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0026] like Figures 1-4 As shown, the highway bridge anti-collision device provided by this embodiment includes an anti-collision bridge pier 1 and an anti-collision guardrail 2 arranged above the anti-collision bridge pier 1, wherein a second support frame 19 is provided on the rear side of the anti-collision bridge pier 1, and the angle between the second support frame 19 and the rear side surface of the anti-collision bridge pier 1 is 45 degrees. The use of the inclined second support frame 19 can improve the support effect of the anti-collision bridge pier 1. When the anti-collision bridge pier 1 is hit, the second support frame 19 prevents the anti-collision bridge pier 1 from being seriously displaced, preventing it from falling under the bridge and causing damage to objects or pedestrians below, and improves the blocking effect to prevent it from falling when a vehicle hits.
[0027] A sliding cavity 3 is provided on the front face of the anti-collision bridge pier 1. A sliding rod 4 is slidably arranged in the sliding cavity 3. A buffer plate 5 is supported on the outer end of the sliding rod 4. The sliding rod 4 is supported and connected to the inner end of the sliding cavity 3 by a first compression spring 6.
[0028] The sliding cavity 3 is inclined upward from the outside to the inside, and the inclination angles of the front and rear sides of the buffer plate 5 are consistent with the inclination direction of the sliding cavity 3. When the buffer plate 5 is hit, the inclined sliding cavity 3 is used to make the buffer plate 5 move obliquely upward. At this time, the upper part of the buffer plate 5 will block the connection between the anti-collision guardrail 2 and the anti-collision bridge pier 1, which can prevent the anti-collision guardrail 2 from breaking, thereby not only improving the service life of the anti-collision device, but also preventing the car from breaking the anti-collision guardrail 2 and falling under the bridge to the greatest extent; ensuring the safety of the people in the car; both sides of the buffer plate 5 are inwardly bent arc structures, and the arc structures on both sides surround the anti-collision bridge pier 1 on both sides, which can not only protect the anti-collision bridge pier 1, but also reduce the damage to the car compared with the angular structure;
[0029] A first support frame 7 for supporting the anti-collision guardrail 2 is provided on the rear side of the upper end surface of the anti-collision bridge pier 1, wherein the bottom end of the first support frame 7 is fixedly connected to the rear side of the upper end surface of the anti-collision bridge pier 1, and the top end of the first support frame 7 is close to and in contact with the anti-collision guardrail 2 in front. The inclined first support frame 7 can support the anti-collision guardrail 2 to prevent severe bending, thereby improving the service life, and can play a good blocking effect to prevent the vehicle from falling when it collides;
[0030] A second sliding cavity 8 is formed at one end of the first support frame 7 close to the anti-collision guardrail 2, and a support rod 9 is slidably arranged in the second sliding cavity 8. The outer end of the support rod 9 supports a buffer support plate 10, and the inner end of the support rod 9 is supported and connected to the inner end of the second sliding cavity 8 by a second compression spring 20;
[0031] Furthermore, the inner walls of the sliding cavity 3 and the second sliding cavity 8 are both provided with rubber pads 12. The provision of the rubber pads 12 can generate a certain damping when the sliding rod 4 and the support rod 9 slide, so that the buffer plate 5 and the buffer support plate 10 further play a buffering effect when they are hit. The front end surfaces of the buffer plate 5 and the buffer support plate 10 are both provided with rubber buffer pads 13. The provision of the rubber buffer pads 13 improves the buffering performance of the buffer plate 5 and the buffer support plate 10 when they are hit, thereby achieving a good unloading effect.
[0032] Furthermore, the front end surface of the rubber buffer pad 13 is provided with a reflective sticker 18, and the front end surfaces of the anti-collision guardrail 2 and the detachable guardrail 11 are also provided with reflective stickers 18. The provision of the reflective stickers 18 facilitates the observation of the anti-collision devices on both sides of the bridge by cars at night, thereby improving the safety of driving at night.
[0033] A detachable guardrail 11 is installed between every two anti-collision guardrails 2; a mounting block 14 is provided on both sides of the anti-collision guardrail 2, and a mounting cavity 15 is provided on the mounting block 14, and a threaded hole 16 is provided on the mounting block 14 to penetrate into the interior of the mounting cavity 15, and threaded holes 16 are also provided at both ends of the detachable guardrail 11, and the two threaded holes 16 are screwed and connected by a threaded rod 17 with a rotating handle; the detachable guardrail 11 can be quickly disassembled and assembled, wherein the maximum gap between each two anti-collision bridge piers 1 is not more than 1.2 meters, so as to ensure that the car will not fall under the bridge through the weaker place between the two anti-collision bridge piers 1. When installing the detachable guardrail 11, the two ends of the detachable guardrail 11 are stuck into the interior of the mounting cavity 15. At this time, the detachable guardrail 11 is communicated with the threaded holes 16 on the mounting block 14, and then the threaded rod 17 is used for screwing and connection.
[0034] like Figures 1-4As shown, the principle of the highway bridge anti-collision device provided by this embodiment is as follows: when a car loses control and collides with the anti-collision device, it first contacts the buffer plate 5. When the buffer plate 5 is hit, the rubber buffer pad 13 on the surface is used for preliminary slight buffering. Then, the buffer plate 5 slides backward by sliding the sliding rod 4 in the sliding cavity 3, and the first compression spring 6 and rubber pad 12 provided inside are used to buffer and unload the impact force, thereby achieving a preliminary energy absorption effect. In addition, the second support frame 19 at the rear can support the anti-collision bridge pier 1 to prevent the occurrence of In the case of severe displacement, when the buffer plate 5 moves backward due to the impact force, the impact force brought by the car will also impact the anti-collision guardrail 2. When the anti-collision guardrail 2 is subjected to the impact force, the rear buffer support plate 10 will slide backward using the support rod 9 sliding in the second sliding cavity 8, and the internal rubber pad 12 and the second compression spring 20 will be used to buffer and unload the impact force, thereby achieving further energy absorption effect. In addition, the buffer support plate 10 is supported by the first support frame 7 at the rear, which can effectively prevent the anti-collision guardrail 2 from bending easily.
