[0021] When installing, two sleeve piece 1 is separated so that it is sleeved on the two sides of front bridge guardrail respectively, is connected and fixed using bolt, if the sleeve piece 1 is sleeved larger space can be used to supplement the wood board that is adapted to sleeve piece 1 is placed, after being fixed, when collision occurs, vehicle directly contacts buffer cotton 7, impact potential will be transmitted to multiple moving rods 9 by support plate 6, and then moving rod 9 moves and forces buffer spring 11 to be compressed, to realize the effect of buffering.
[0022] By setting two sleeve piece 1, two sleeve piece 1 is fixed on the guardrail of bridge by multiple bolts, so that the buffer anti-collision device is installed and fixed, the buffer mechanism is set, when collision occurs, the impact force brought by vehicle body will be transmitted to moving rod 9 through support plate 6 and buffer cotton 7, and then moving rod 9 moves and makes buffer spring 11 compressed, so that the impact force is attenuated by the characteristics of buffer spring 11, so as to avoid greater loss caused by direct collision, the device is easy to install, improves the safety of bridge engineering, and is high in practicality.
[0023] It should be noted that when the external force acts on the buffer spring 11, the buffer spring 11 is deformed under stress, and the kinetic energy of the external force is converted into elastic energy storage. This energy conversion makes the compression or stretching of the external force acting on the buffer spring 11 more uniform, and stores the kinetic energy in the buffer spring 11, thereby achieving the effect of buffering.
[0024] Further, as shown in Figure 1 and Figure 2 , the collision is mostly from the side, and when the collision occurs from the side, the moving rod 9 will displace a small section in the waist-shaped hole 5, thereby moving the moving rod 9, avoiding the situation of being stuck, and achieving the purpose of compressing the buffer spring 11.

After being fixed, when a collision occurs, the vehicle directly contacts the buffer cotton 7, and the impact potential is transmitted to a plurality of moving rods 9 through the support plate 6, and then the moving rods 9 move to force the buffer spring 11 to be compressed. When the external force acts on the buffer spring 11, the buffer spring 11 is deformed under stress, and the kinetic energy of the external force is converted into elastic energy storage. This energy conversion makes the compression or stretching of the external force acting on the buffer spring 11 more uniform, and stores the kinetic energy in the buffer spring 11, thereby achieving the effect of buffering.
[0028] By setting two sleeve fittings 1, two sleeve fittings 1 are fixed on the guardrail of the bridge through a plurality of bolt sleeve fittings, so that the buffer anti-collision device is realized installation and fixation, and the buffer mechanism is arranged, when collision occurs, the impact force brought by the vehicle body is transmitted to the moving rod 9 through the supporting plate 6 and the buffer cotton 7, and then the moving rod 9 is forced to move to compress the buffer spring 11, so that the impact force is attenuated through the characteristics of the buffer spring 11, so that the loss caused by direct collision is avoided, the device is convenient to install, the safety of the bridge engineering is improved, and the practicality is high.
