Description

Technical Field

[0001] This utility model relates to the field of road collision avoidance technology, specifically to a collision avoidance device for road transportation engineering. Background Technology

[0002] Road traffic collision avoidance devices are facilities or devices installed to reduce or prevent collisions between vehicles and other objects during travel. These devices are mainly divided into two categories: road collision avoidance facilities and vehicle collision avoidance devices.

[0003] Existing road crash barriers mainly include corrugated beam guardrails and concrete guardrails. Corrugated beam guardrails have a certain degree of elasticity, but the distance between the posts of each section of corrugated beam guardrail is relatively large, and they are mostly flexible structures with poor impact resistance. Concrete guardrails have greater strength and high impact resistance, but when a vehicle hits a concrete guardrail, although the stopping effect is very good, it will also cause significant damage to the vehicle. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing road traffic collision avoidance facilities come in various styles, some have poor impact resistance, and others are prone to significant damage from multiple vehicles.

[0005] To solve the above problems, the technical solution adopted by this utility model is a collision avoidance device for road transportation engineering, including a steel frame structure. The steel frame structure includes a main support frame, a bent rod fixed on one side of the main support frame, several pairs of baffles fixed on the outside of the bent rod, a guide short roller rotatably connected between each pair of baffles on the outside of the bent rod, a square connecting rod fixed between every two adjacent bent rods, a connecting shaft fixed in the middle of the square connecting rod, a guide long roller rotatably connected on the outside of the connecting shaft, an auxiliary support frame fixed on one side of the main support frame, a pair of fastening rods fixed between the main support frame and the square connecting rod, and reflective strips fixed on the sides of both the guide long roller and the guide short roller.

[0006] As a further aspect of this invention, both the long guide roller and the short guide roller are made of composite materials such as EVA and polyurethane. These materials not only have excellent elasticity but also possess outstanding wear resistance and impact resistance.

[0007] As a further embodiment of this invention, both the long guide roller and the short guide roller have a honeycomb-shaped hollow structure inside, which can improve impact resistance.

[0008] As a further embodiment of this invention, the long guide roller and the short guide roller have the same radius, which facilitates contact with the outer surface of the vehicle.

[0009] As a further embodiment of this invention, three short guide rollers are provided on the side of the bending rod to reduce the impact on the bending rod.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds a guide long roller and a guide short roller structure. When a vehicle hits the roller, the roller will rotate after contacting the surface of the roller, which will cause the vehicle to deviate slightly in the direction of impact, thereby reducing the impact force. In addition, the steel frame structure is added, which can improve the overall impact resistance of the guardrail. Attached Figure Description

[0018] 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.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0020] Combined with appendix Figure 1 , 24. It can be seen that the structure includes a steel frame, which includes a main support frame 1. A bent rod 2 is fixed on one side of the main support frame 1 to improve the impact resistance of the facility. Several pairs of baffles are fixed on the outside of the bent rod 2. A square connecting rod 4 is fixed between every two adjacent bent rods 2. A connecting shaft 5 is fixed in the middle of the square connecting rod 4. An auxiliary support frame 7 is fixed on one side of the main support frame 1 to further improve the impact resistance of the facility. A pair of fastening rods 8 are fixed between the main support frame 1 and the square connecting rod 4 to improve the impact resistance of the square connecting rod 4.

[0021] Combined with appendix Figure 1-3 It can be seen that three short guide rollers 3 are rotatably connected to the outside of the bent rod 2 between each pair of baffles, and a long guide roller 6 is rotatably connected to the outside of the connecting shaft 5. The long guide roller 6 and the short guide roller 3 are both made of composite materials such as EVA and polyurethane. These materials not only have excellent elasticity, but also have excellent wear resistance and impact resistance. The long guide roller 6 and the short guide roller 3 have a honeycomb hollow structure inside, which can improve the impact resistance. The long guide roller 6 and the short guide roller 3 have the same radius, which can facilitate contact with the outer surface of the vehicle. The long guide roller 6 and the short guide roller 3 are fixed with reflective strips 9 on their sides, which can reflect vehicle lights at night and indicate the road boundary.

[0022] The working principle of this application is as follows: When installing the facility, first install the long guide roller 6 and the short guide roller 3 on the outside of the connecting shaft 5 and the bent rod 2, and then fix the main support frame 1 and the auxiliary support frame 7 to the edge of the road for protection.

[0023] When a vehicle deviates from the road and crashes obliquely into the long guide roller 6 and the short guide roller 3, the outer side of the vehicle will come into contact with the surfaces of the long guide roller 6 and the short guide roller 3. When the surfaces of the long guide roller 6 and the short guide roller 3 are subjected to the impact force, they will rotate, guiding the vehicle to continue moving forward, thereby reducing the force on the facility and the impact force on the vehicle. At the same time, the bending rod 2, the square connecting rod 4, the fastening rod 8, and the auxiliary support frame 7 will be subjected to the impact force, preventing the vehicle from rushing out of the facility and slowing down the vehicle's movement speed.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
