Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanized guardrail structures, and particularly relates to a high guardrail with a hot-dip galvanized film impact-resistant structure. Background Art

[0002] The reason why hot-dip galvanized film guardrails are favored is inseparable from their unique technical characteristics. First of all, the hot-dip galvanizing technology forms a dense zinc film on the surface of steel, effectively preventing the corrosion of steel and greatly extending the service life of the guardrail. Secondly, the zinc film has excellent adhesion and ductility, which can ensure that the guardrail is not easily deformed or damaged when subjected to external force impact. In addition, the hot-dip galvanized film guardrail also has excellent weather resistance and ultraviolet resistance, and can maintain stable performance in various harsh environments.

[0003] In the prior art, such as a high guardrail with a hot-dip galvanized film impact-resistant structure proposed in the publication number CN217399486U, which includes a guardrail. A buffer plate is slidably connected to the outer side of the interior of the guardrail. A limiting plate is fixedly connected to the top end behind the buffer plate. A hollow plate is fixedly connected to the rear of the guardrail. A top block is fixedly connected to the rear of the limiting plate. A hollow block is slidably connected to the outer side of the top block. A rubber block is fixedly connected to the top end behind the interior of the hollow block. A bottom rod is fixedly connected to the lower end surface of the guardrail. In the utility model, through the arranged rubber block, the impact force of the car hitting the outer side of the buffer plate on the guardrail can be effectively reduced, and the impact resistance of the guardrail can be effectively improved. At the same time, sliding rods and compression springs are arranged at the rear sides of the left and right sides of the limiting plate, so that the buffer plate is always fixed to the outer side of the guardrail. At the same time, the compression spring also has a certain impact resistance, which can protect the vehicle and also protect the guardrail to a certain extent, which is very practical.

[0004] When this application is in use, through the arranged rubber block, the impact force of the car hitting the outer side of the buffer plate on the guardrail can be effectively reduced, and the impact resistance of the guardrail can be effectively improved. At the same time, sliding rods and compression springs are arranged at the rear sides of the left and right sides of the limiting plate, so that the buffer plate is always fixed to the outer side of the guardrail. At the same time, the compression spring also has a certain impact resistance. However, if it encounters a large impact, it is not convenient for this guardrail to quickly buffer the impact force of the car, and the inside of the guardrail structure is easily quickly squeezed, and finally the guardrail is separated from the bottom rod, resulting in the rapid damage of the bottom rod.

Specific implementation mode

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment:

[0026] Referring to Figures 1-4 , a height guardrail with a hot-dip galvanized film impact-resistant structure disclosed by the present invention includes two bottom columns 1. The top ends of the two bottom columns 1 are fixedly connected with installation columns 2. The bottom ends of the installation columns 2 are inserted into the bottom columns 1. A first corrugated guardrail plate 3 is fixedly connected between the two installation columns 2. A second corrugated guardrail plate 5 is connected to the sides of the two installation columns 2 through a buffer 4. An auxiliary part 6 is installed between the first corrugated guardrail plate 3 and the second corrugated guardrail plate 5.

[0027] In this embodiment, during installation, the bottom column 1 is buried in the concrete floor. The provided installation column 2 can be installed at the top end of the bottom column 1 by bolts or welding. The provided first corrugated guardrail plate 3 can also be installed between the two installation columns 2 by welding or bolt connection. The provided second corrugated guardrail plate 5 is connected through the buffer 4. The second corrugated guardrail plate 5 faces the road surface. After being collided, pressure is relieved through the provided buffer 4, and at the same time, the auxiliary part 6 assists to prevent the second corrugated guardrail plate 5 from breaking in the middle, thereby improving the strength of the guardrail plate.

[0028] In a further preferred embodiment of the present invention, as Figures 2-3 shown, the buffer 4 includes two through grooves 7. The two through grooves 7 are opened on the sides of the installation column 2. A sliding rod 8 is arranged in the through groove 7. The end of the sliding rod 8 is fixedly connected with the second corrugated guardrail plate 5. A positioning ring 9 and a sliding ring 10 are respectively arranged at both ends in the through groove 7. The positioning ring 9 is fixedly connected with the through groove 7 and is slidably connected with the sliding rod 8. The sliding ring 10 is slidably connected with the through groove 7 and is fixedly connected with the sliding rod 8. A tension spring 11 is fixedly connected between the positioning ring 9 and the sliding ring 10.

[0029] In this embodiment, when the second arc-shaped guardrail plate is collided, the sliding rod 8 provided therein can slide on the positioning ring 9 in the chute, thereby driving the sliding ring 10 to slide. The provided tension spring 11 provides preliminary buffering. When the impact force is small, it can be directly bounced back by the tension spring 11, so as to achieve the effect of protecting the vehicle and preventing the vehicle from rushing out of the guardrail.

[0030] In a further preferred embodiment of the present utility model, as Figures 2-3 shown, a cavity tube 12 is provided at one end of the sliding rod 8 away from the second corrugated guardrail plate 5. The cavity tube 12 is fixedly connected to the outer side wall of the mounting column 2. The end of the sliding rod 8 extends into the cavity tube 12. One end of the cavity tube 12 close to the sliding rod 8 is provided with a closed end. A piston plate 13 is fixedly connected to one end of the sliding rod 8 located in the cavity tube 12. The piston plate 13 is piston-connected to the cavity tube 12. Two leakage holes 20 are formed in the piston plate 13. A compensating piston piece 14 is piston-connected in the cavity tube 12.

[0031] In this embodiment, when the second corrugated guardrail plate 5 is subjected to a large impact, at this time, the second corrugated guardrail plate 5 is pushed to move rapidly, thereby quickly pushing the sliding rod 8 into the cavity tube 12. The sliding rod 8 and the sliding ring 10 are subjected to the acting force of the tension spring 11 for preliminary buffering. Subsequently, the piston plate 13 will quickly perform a piston movement towards the inside of the cavity tube 12. The cavity tube 12 is filled with damping liquid, and the damping liquid will flow towards the mounting column 2 through the leakage holes 20, so as to achieve the effect of unloading and buffering through the piston movement of the piston plate 13 and the viscous resistance of the damping liquid. At the same time, as the sliding rod 8 moves into the cavity tube 12, it will drive the compensating piston piece 14 to perform a piston movement, thereby preventing the reduction of the storage space of the damping liquid caused by the entry of the sliding rod 8 and resulting in cylinder explosion. After unloading, the impact force on the guardrail is greatly reduced, and the second corrugated guardrail plate 5 is prevented from being directly bent after being hit hard, resulting in the vehicle rushing out of the road.

[0032] In a further preferred embodiment of the present utility model, as Figure 4 shown, the auxiliary member 6 includes two support rods 15. The ends of the two support rods 15 are fixedly connected to one side of the second corrugated guardrail plate 5 close to the first corrugated guardrail plate 3. A reinforcing rod 16 is connected between one ends of the two support rods 15 close to the second corrugated guardrail plate 5.

[0033] In this embodiment, the provided support rods 15 are used to fix the reinforcing rod 16, so that the reinforcing rod 16 is fixed on the second corrugated guardrail plate 5. The middle strength of the second corrugated guardrail plate 5 is improved through the reinforcing rod 16, and it is prevented from being directly broken after being collided, thereby reducing the anti-collision ability.

[0034] In a further preferred embodiment of the present utility model, as Figure 1 andFigure 4 As shown, a cavity rod 17 is provided on the first corrugated guardrail plate 3. The end of the cavity rod 17 passes through the first corrugated guardrail plate 3 and is fixedly connected to the first corrugated guardrail plate 3. The end of the support rod 15 is piston-connected to the cavity rod 17, and an exhaust hole 18 is provided at one end of the cavity rod 17 away from the support rod 15.

[0035] In this embodiment, when the second corrugated guardrail plate 5 is collided, it will quickly drive the support rod 15 to move inside the cavity rod 17. Due to the rapid movement of the support rod 15 after being collided, the diameter of the exhaust hole 18 is small and the internal air cannot be ejected instantly, so the internal air pressure will be increased to block the movement of the second corrugated guardrail plate 5. In addition, it will cooperate with the return spring 19 to block, further improving the overall impact resistance of the guardrail. At the same time, it can cooperate with the first corrugated guardrail plate 3 to bear the impact force together, improving the overall stability of the guardrail.

[0036] In a further preferred embodiment of the present invention, as Figure 1 and Figure 4 shown, a return spring 19 is provided between the cavity rod 17 and the second corrugated guardrail plate 5. Both ends of the return spring 19 are fixedly connected to the second corrugated guardrail plate 5 and the cavity rod 17 respectively.

[0037] In this embodiment, after the second corrugated guardrail plate 5 is collided, the return spring 19 and the tension spring 11 are respectively squeezed and stretched. The second corrugated guardrail plate 5 is driven to reset by the reaction forces of the two.

[0038] Both the first corrugated guardrail plate 3 and the second corrugated guardrail plate 5 are provided with hot-dip galvanized films on their surfaces, improving the antioxidant and anti-corrosion capabilities.

[0039] The embodiments of this specific implementation manner are all preferred embodiments of the present invention. The protection scope of the present invention is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
