[0018] like Figure 1 , Figure 2 As shown, a collision avoidance device for safety management of highway bridge engineering comprises a mounting base plate 1, a column 2 and an collision avoidance assembly, wherein the column 2 is fixed on the mounting base plate 1, the collision avoidance assembly is detachably connected to the column 2, the collision avoidance assembly comprises an collision avoidance block 3 and a first buffer assembly 4, a second buffer assembly 5 and a third buffer assembly 6 which are sequentially connected between the collision avoidance block 3 and the column 2, the collision avoidance block 3 comprises a hollow chamber formed by an inner guard plate 32 and an outer arched guard plate 31 and a plurality of rubber strips 33 arranged in the hollow chamber, the longitudinal cross section of the rubber strip 33 is an arc-shaped structure tangent to the outer arched guard plate 31.
[0019] The first buffer assembly 4 includes a first metal shell 41 and a first buffer spring. The first metal shell 41 is divided from top to bottom into a plurality of concave installation cavities by a partition bar 411. A slide groove 413 is provided on both side walls of each concave installation cavity. A slider 412 is slidably connected to the slide groove 413. The upper and lower ends of the anti-collision block 3 are connected to the slider 412. The first buffer spring is connected between the concave installation cavity and the anti-collision block 3. When impacted, the anti-collision block 3 moves along the inner wall of the first metal shell 41 to squeeze the first buffer spring 42, thereby buffering the impact force.
[0020] The second buffer assembly 5 includes a second metal shell 51 and a second buffer spring 52. The second buffer assembly 5 is installed in the second metal shell 51. The first metal shell 41 is slidably connected to the inner wall of the second metal shell 51. The second buffer spring 52 is connected between the first metal shell 41 and the second buffer assembly 5. Under the reaction force of the first buffer spring 42, the first metal shell 41 moves along the inner wall of the second metal shell 51 to squeeze the second buffer spring 52, thereby performing secondary buffering on the impact force.
[0021] The third buffer assembly 6 includes a wedge block 61, a connecting block 62 and a third buffer spring 63. The wedge blocks 61 are arranged on both sides of the second metal shell 51 and are slidably connected to the bottom of the second metal shell 51.

[0024] The working process of this embodiment is as follows:
[0025] When a collision occurs, the rubber strip 33 in the anti-collision block 3 is squeezed to absorb the impact energy and play a buffering and protective role. When the impact energy is too large, the anti-collision block 3 will drive the first metal shell 41 to move due to the impact force. At the same time, the first metal shell 41 drives the connecting block 62 to move, and the wedge shape is pushed to move under the action of the connecting block 62. In this process, multiple buffering protections are performed through the first buffer spring 42, the second buffer spring 52 and the third buffer spring 63 to effectively absorb the impact energy, achieve the purpose of good buffering and anti-collision performance, and better prevent damage caused by highway bridge facilities.
