Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a wing wall-free guardrail. Background Art

[0002] Highway guardrails are a type of guardrail that is not easily destroyed by vehicles and can provide good protection for vehicles and passengers. Concrete wing walls are mostly used for transition between highway, bridge section guardrails and roadbed section guardrails. This method of directly connecting the guardrail to the wall can effectively save space and provide a simple appearance, so it is widely used.

[0003] After searching, the existing patent (Announcement No.: CN218090514U) discloses a wing-wall-free transition section guardrail, which is arranged between the bridge guardrail and the highway guardrail, including a first support column, a second support column and a third support column arranged at equal intervals from the highway guardrail to the bridge guardrail, the first support column, the second support column and the third support column are fixedly installed on the ground, a corrugated anti-collision plate is arranged along the bridge guardrail to the highway guardrail, the corrugated anti-collision plate is fixedly installed on the bridge guardrail section roadbed through a fixed bracket, and a protective beam is arranged along the bridge guardrail to the highway guardrail, one end of the protective beam is fixedly installed on the bridge guardrail section roadbed, and the other end extends to the side of the first support column away from the road surface. A wing-wall-free transition section guardrail has a simple structure, is easy to install, and has a short construction time. It effectively replaces the role of the wing wall. At the same time, when a collision occurs, it can effectively guide the collision vehicle to avoid more serious traffic injuries.

[0004] However, in the above scheme, the safety is poor. When a vehicle collides, the wing-free wall guardrail can effectively prevent the vehicle from sliding out, but the collision energy between the two is large, and it is inconvenient to guide the vehicle to consume the impact energy, which leads to its poor safety.

[0005] In view of this, the utility model proposes a wing wall-free guardrail. Utility Model Content

[0006] The utility model provides a wing wall-free guardrail, which solves the problem of poor safety in the related technology.

[0007] The technical solution of the utility model is as follows: a wing-wall-free guardrail comprises a concrete guardrail, a lap plate is fixedly connected to one side of the front of the concrete guardrail, a supporting column is movably connected to one side of the concrete guardrail at equal intervals, a bracket is fixedly connected to the upper end of the front of the supporting column, a three-wave plate is fixedly connected to the front of the bracket and the lap plate, a connecting frame is fixedly connected to the front of the supporting column below the bracket, a friction beam is fixedly connected to the front of the connecting frame, an upper guide plate is fixedly connected to the front of the supporting column below the friction beam, a lower guide plate is fixedly connected to the front of the supporting column below the upper guide plate, and rubber wheels are rotatably connected to the inner walls of the upper guide plate and the lower guide plate at equal intervals. When a vehicle collides with the friction beam and the three-wave plate, the rotating rubber wheels are used to enable the vehicle to slide along the surface of the three-wave plate, and cooperate with the friction beam to consume the impact energy of the vehicle, thereby improving its anti-collision effect and avoiding direct collision of the vehicle with the friction beam and the three-wave plate, resulting in the impact energy directly acting on the vehicle and causing safety hazards.

[0008] Preferably, the surface of the rubber wheel extends to the outside of the upper guide plate and the lower guide plate, and the ends of the friction beam, the upper guide plate and the lower guide plate away from the supporting column are all in the same vertical plane, so that when the vehicle collides, it can first contact the rubber wheel to achieve preliminary buffering and collision prevention and guide vehicle movement.

[0009] Preferably, a slope is provided on one side of the top of the lower guide plate, and the slope has an inclination angle of thirty degrees to the vertical direction, so as to guide rainwater falling to the top of the lower guide plate and reduce the accumulation of rainwater at the top of the lower guide plate.

[0010] Preferably, the three-wave plate is wavy in shape in side view, and the three-wave plate is fixedly connected to the front side of the bracket by bolts to prevent an out-of-control vehicle from running off the road.

[0011] Preferably, the shape of the bracket in a top view is a "π" shape, and the height of the bracket is less than the height of the three-wave plate, thereby improving the structural strength of the connection between the support column and the three-wave plate.

[0012] Preferably, a reinforcement block is welded at the middle position of the inner wall of the bracket, and one end of the reinforcement block is engaged with the middle position inside the three-wave plate, thereby reinforcing the structural strength of the bracket itself and making it more closely contact with the middle position inside the three-wave plate, further improving the firmness and stability of the three-wave plate installation.

[0013] Preferably, a groove is provided at the other end of the reinforcement block, and the shape of the groove in a top view is arc-shaped, which ensures the structural strength of the reinforcement block while reducing the deadweight of the reinforcement block to reduce costs.

[0014] Preferably, one end of the lap plate is in contact with the upper end of the outer surface of the concrete guardrail, and the lap plate has a "knife" shape in a side view, which facilitates the connection and installation between one side of the three-wave plate and the concrete guardrail.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. The utility model provides supporting columns, rubber runners, friction beams, three-wave plates, upper guide plates, lower guide plates, brackets, connecting frames and reinforcing blocks. When a vehicle collides with the friction beam and the three-wave plate, the elastic deformation of the rubber runner itself can be used to absorb a part of the collision energy of the vehicle. The rotating rubber runner can be used to allow the vehicle to slide along the surface of the three-wave plate, and cooperate with the friction beam to consume the impact energy of the vehicle, thereby improving its anti-collision effect and avoiding the impact energy directly acting on the vehicle due to direct collision between the vehicle and the friction beam and the three-wave plate, thereby preventing the three-wave plate from being further supported and reinforced by the bracket and the reinforcing block, and reinforcing the friction beam by the connecting frame, thereby improving the structural strength of the friction beam and the three-wave plate, thereby avoiding excessive deformation of the friction beam and the three-wave plate due to excessive collision of the vehicle, thereby improving its safety and anti-collision performance.

[0017] 2. The structure of the utility model is more convenient to install and has a short construction time. It can effectively replace the role of the wing wall. At the same time, when a collision occurs, it can effectively guide the colliding vehicle to avoid more serious traffic injuries and improve its practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The preferred embodiment of the wing-free wall guardrail provided by the utility model is as follows: Figures 1 to 5 As shown: a wing-wall-free guardrail, comprising a concrete guardrail 1, a lap plate 12 is fixedly connected to one side of the front of the concrete guardrail 1, a support column 2 is movably connected to one side of the concrete guardrail 1 at equal intervals, a bracket 8 is fixedly connected to the upper end of the front of the support column 2, a three-wave plate 5 is fixedly connected to the front of the bracket 8 and the lap plate 12, a connecting frame 9 is fixedly connected to the front of the support column 2 below the bracket 8, a friction beam 4 is fixedly connected to the front of the connecting frame 9, an upper guide plate 6 is fixedly connected to the front of the support column 2 below the friction beam 4, a lower guide plate 7 is fixedly connected to the front of the support column 2 below the upper guide plate 6, and rubber runners 3 are rotatably connected to the inner walls of the upper guide plate 6 and the lower guide plate 7 at equal intervals. When a vehicle collides with the friction beam 4 and the three-wave plate 5, the rotating rubber runner 3 is used to allow the vehicle to slide along the surface of the three-wave plate 5, and cooperate with the friction beam 4 to consume the impact energy of the vehicle, so as to avoid direct collision of the vehicle with the friction beam 4 and the three-wave plate 5, resulting in the impact energy directly acting on the vehicle and causing safety hazards.

[0027] In this embodiment, the surface of the rubber wheel 3 extends to the outside of the upper guide plate 6 and the lower guide plate 7, and the ends of the friction beam 4, the upper guide plate 6 and the lower guide plate 7 away from the support column 2 are all in the same vertical plane. By using a larger rubber wheel 3, the vehicle can first contact the rubber wheel 3 when colliding, thereby achieving preliminary buffering and anti-collision and guiding vehicle movement.

[0028] In this embodiment, a slope 13 is provided on one side of the top of the lower guide plate 7, and the inclination angle of the slope 13 to the vertical direction is thirty degrees. The inclined slope 13 is used to guide rainwater falling to the top of the lower guide plate 7, thereby reducing the accumulation of rainwater at the top of the lower guide plate 7.

[0029] In this embodiment, the three-wave plate 5 is wavy in shape in the side view, and the three-wave plate 5 is fixedly connected to the front side of the bracket 8 by bolts. The wavy three-wave plate 5 is used to prevent an out-of-control vehicle from running off the road.

[0030] In this embodiment, the shape of the bracket 8 in the top view is "π"-shaped, and the height of the bracket 8 is less than the height of the three-wave plate 5. The "π"-shaped bracket 8 is used to improve the structural strength of the connection between the support column 2 and the three-wave plate 5.

The welded reinforcement block 10 is used to reinforce the structural strength of the bracket 8 itself, and it is in closer contact with the middle position inside the three-wave plate 5, thereby further improving the firmness and stability of the installation of the three-wave plate 5.

[0032] In this embodiment, a groove 11 is formed at the other end of the reinforcement block 10, and the shape of the groove 11 in a top view is arc-shaped. The arc-shaped groove 11 is used to ensure the structural strength of the reinforcement block 10 while reducing the weight of the reinforcement block 10 to reduce costs.

[0033] In addition, one end of the lap plate 12 is in contact with the upper end of the outer surface of the concrete guardrail 1, and the shape of the lap plate 12 in the side view is a "knife" shape. The "knife"-shaped lap plate 12 is used to facilitate the connection and installation between one side of the three-wave plate 5 and the concrete guardrail 1.

[0034] The working principle and use process of the utility model are as follows: first, the support columns 2 are installed and fixed on the roadside on one side of the concrete guardrail 1 at equal intervals in sequence, and then the lap plate 12 is installed and fixed on the upper end of the front side of the concrete guardrail 1, and then the bracket 8 and the connecting frame 9 are used to realize the installation and fixation of the friction beam 4 and the three-wave plate 5, and the middle position inside the three-wave plate 5 will be stuck to one end of the reinforcement block 10, and at the same time, the welded reinforcement block 10 is used to reinforce the structural strength of the bracket 8 itself, and it is more closely in contact with the middle position inside the three-wave plate 5, further improving the firmness and stability of the installation of the three-wave plate 5, and then the upper guide plate 6 and the lower guide plate 7 are installed and fixed on the lower end of the front side of the support column 2;

[0035] Afterwards, during its normal use, when the vehicle accidentally collides with the friction beam 4 and the three-wave plate 5, the elastic deformation of the rubber runner 3 itself can be used to absorb a part of the vehicle's collision impact energy, and the rotating rubber runner 3 can be used to allow the vehicle to slide along the surface of the three-wave plate 5, and cooperate with the friction beam 4 to frictionally consume the vehicle's impact energy, thereby improving its anti-collision effect, and avoiding the vehicle directly colliding with the friction beam 4 and the three-wave plate 5, causing the impact energy to directly act on the vehicle and cause safety hazards. At the same time, the friction beam 4 and the three-wave plate 5 are reinforced by the above structure, thereby improving the structural strength of the friction beam 4 and the three-wave plate 5, and avoiding excessive deformation of the friction beam 4 and the three-wave plate 5 due to excessive collision of the vehicle, which may cause the vehicle to rush out.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
