Technical Field

[0001] The invention relates to the technical field of agricultural planting, in particular to a highway guardrail which is easy to assemble. Background Art

[0002] When a vehicle hits a corrugated guardrail, it will deform and bounce the vehicle away. However, the force used to bounce the vehicle away mainly comes from the elasticity of the corrugated plate itself, and the degree of force unloading is limited. The vehicle still carries a large amount of kinetic energy after being bounced away, and the danger is still great. In addition, since the corrugated plate cannot unload force well, it is easily damaged by impact, causing the vehicle to fly out. Summary of the invention

[0010] Compared with the prior art, the present invention has the following beneficial effects: The highway guardrail of the present invention is easy to assemble. By setting a torsion arm structure, the ability of the guardrail to absorb kinetic energy is increased. On the one hand, damage to the guardrail is reduced to prevent vehicles from flying out.

[0013] See also Figure 1-5 , a highway guardrail that is easy to assemble, including a plurality of piles 1 inserted into the ground, the piles 1 are arranged side by side, the top of the pile 1 is fixedly connected with a mounting plate 2, the mounting plate 2 is welded to the pile 1 in advance, the two ends of the top of the mounting plate 2 are connected with a torsion arm 3, the torsion arm 3 is rotatable relative to the mounting plate 2, and there is a large torsional damping when rotating, the end of the torsion arm 3 is fixed with a buffer connector 4, the two buffer connectors 4 close to each other of two adjacent piles 1 are jointly fixed with a corrugated plate 5, and a spacing is set between two adjacent corrugated plates 5. When the corrugated plate 5 is hit by a vehicle, the torsion arm 3 will twist, and when twisting, it will unload a part of the impact force of the corrugated plate 5, and then the buffer connector 4 and the corrugated plate 5 will deform, absorbing a part of the impact force when deforming, and the remaining impact kinetic energy will be transferred to the vehicle through the corrugated plate 5 to bounce the vehicle away.

[0014] The reason why the torsion arm 3 needs a large torque when rotating is due to the following structure: two flower-shaped keyways 6 are provided on the top of the mounting plate 2, and the flower-shaped keyways 6 are countersunk grooves, and an anti-torsion rubber ring 7 is inserted in the flower-shaped keyways 6. The outer edge of the anti-torsion rubber ring 7 is also arranged in a flower-shaped pattern and matches the flower-shaped keyways 6. A plurality of slots 11 are arranged in the inner circle of the anti-torsion rubber ring 7. The bottom of the torsion arm 3 is arranged in a cylindrical plug post 8, and a protrusion 9 is arranged on the side wall of the plug post 8, and the protrusion 9 is inserted in the slot 11. When the torsion arm 3 is subjected to a torsion force, the anti-torsion rubber ring 7 will generate a reverse torsion force on it, just absorbing the kinetic energy on the torsion arm 3.

[0015] A through hole is provided on the side wall of the plug post 8 near the bottom, and a limiting bolt is inserted into the through hole to prevent the plug post 8 from being pulled out upwards.

[0016] The buffer connector 4 is a multi-prism cylindrical structure, and the buffer connector 4 and the corrugated plate 5 are fixedly connected by bolts. When the corrugated plate 5 is hit, the buffer connector 4 absorbs the impact kinetic energy and deforms. The elasticity of the above structure can convert the absorbed impact kinetic energy into elastic potential energy, reducing material damage.

[0017] The spacing between two adjacent corrugated plates 5 is 10-15 cm. Due to the rotation of the torsion arm 3, the corrugated plates 5 will move to a certain extent. The spacing between adjacent corrugated plates 5 can make room for their movement.

[0018] One end of the cantilever 3 connected to the buffer connector 4 faces the center of the road, and the angle between the cantilever 3 and the mounting plate 2 is 90 degrees after being fixed during installation. The installation angle of the cantilever 3 is unified to facilitate the assembly of the corrugated plate 5.
