Compared with the traditional guardrail technology, the anti-collision safety guardrail used for the municipal road and bridge engineering can ensure that the guardrail is prevented from being collided by a vehicle by changing the wave shape when the guardrail is collided by the vehicle.
According to the guardrail plate base, the guardrail shell can be supported, the connecting mechanism arranged between two adjacent guardrail units can be used for connecting the two adjacent guardrail units, and mutual interference cannot be caused when an angle is changed between the two adjacent guardrail units; the connecting mechanism arranged between two adjacent guardrail plates has the function of connecting the two adjacent guardrail plates, and the mutual interference cannot be caused when the angle change occurs between the two adjacent guardrail plates; the connecting mechanism arranged between the handrail shell and the guardrail plate has the function of connecting the handrail shell and the guardrail plate, and the mutual interference cannot be caused when the angle change occurs between the handrail shell and the guardrail plate; the guardrail base arranged on the lower side of the guardrail plate plays a role in supporting the guardrail plate, and when the guardrail plate is impacted, the guardrail base can counteract a part of impact force applied to the guardrail plate through friction between the guardrail base and the ground and plays a role in drawing the impacted guardrail unit; two belt pulleys installed in two adjacent guardrail units can mutually transmit power through the matching of a belt; the spiral spring arranged in the middle of the rotating shaft has the function that the spiral spring can provide restoring force for the rotating shaft in the guardrail after the guardrail is impacted, so that the rotating shaft rotates along the opposite direction, and meanwhile, the spiral spring can also play a role in resetting the trigger plate; the fixed shaft sleeves arranged at the upper end and the lower end of the rotating shaft can fix the rotating shaft on the inner side of the railing shell; the two steel rope wheels arranged between the two fixed shaft sleeves have the functions that when the rotating shaft drives the steel rope wheels to rotate, the steel rope wheels drive the steel ropes wound on the outer circular surfaces of the steel rope wheels to move, further drive the elastic strips connected with the steel ropes to move, and finally control the angles between the three guardrail plates through the elastic strips; through the matching of the rack and the transmission gear, the transmission gear arranged on the rotating shaft can rotate when the rack moves, and the rotating shaft is driven to rotate while the transmission gear rotates; when the trigger plate is subjected to external force, the trigger plate gradually moves towards the inner side of the trigger plate hole, and the rack arranged on the trigger plate also moves towards the trigger plate hole in the moving process of the trigger plate; the trigger plate can reciprocate in the trigger plate hole through the matching of the guide block and the guide groove; the belt may pass through the belt hole to connect two adjacent pulleys mounted in the two guard rail units together, and may transmit power on the two pulleys. The belt pulley between the two guardrail units drives the rotating shaft to rotate while rotating, at the moment, the steel rope pulley drives the steel rope to move, and the steel rope drives the elastic strip connected with the steel rope to move when moving; when the guardrail unit is impacted by an automobile, the side of the arc-shaped protrusion of the guardrail unit faces the impact direction of the automobile, so that the stability of the guardrail unit can be improved, and the guardrail unit is not easy to knock down; and one part of the elastic strip positioned in the through hole of the guardrail plate is in a bow shape with opposite and alternative directions.
When the impact force is small, the original linear state is expected to be maintained between the guardrail plates in the design, the guardrail units swing at a certain angle, the collided guardrail is dragged by the non-collided guardrail, the swing angle between the guardrail units is gradually reduced along with the angle in the direction away from the collided guardrail units by the designed leaf spring, and the design can weaken the triggered resistance of the trigger plate and enable the adjacent guardrail units to deform smoothly; the angle formed between the guardrail units can cause that adjacent belt pulleys between the guardrail units can mutually rotate at a small angle, so that the steel rope can inevitably move in a small displacement manner, the two ends of the middle straightening part of the designed elastic strip stretch between the two guardrail plates, the length of the part of the straightening part positioned in the guardrail plates is greater than the distance of the small displacement movement of the steel rope, and the arc part can not influence the guardrail plates; the length of the straightened elastic strip in the through hole of the guardrail plate in the elastic strip designed by the invention is the same as that of the straightened elastic strip in the gap between the adjacent guardrail units, so that the arched elastic strip cannot be pulled out of the through hole of the guardrail plate due to insufficient force when the steel rope pulls the elastic strip to move.
When the bow-shaped elastic strip is subjected to a large force, i.e. when the force of a car impact is large enough, the straightened portion will be completely pulled out of the through hole of the guardrail plate and the bow portion will be pulled to the gap between two adjacent guardrail units, thereby changing the guardrail units into a bow shape.
When the guardrail is in a normal state, the elastic strip is positioned in the through hole on the guardrail plate, and the elastic strip is positioned between the gaps of the two guardrail plates and is in a straightened state; when an automobile running on a road sideslips and collides with a guardrail arranged in the middle of the road and the impact force of the automobile to the guardrail is large, an engine hood of the automobile collides with the collision plate; when the impact plate is subjected to the impact force of the automobile, a thrust force is applied to the trigger plate arranged on one side of the impact plate; under the action of thrust, the trigger plate moves towards the inner side of the trigger plate hole through the matching of the guide block and the guide groove, and the trigger plate drives the rack arranged on the inner side of the trigger plate hole to move towards the inner side of the trigger plate hole while moving; because the rack is meshed with the transmission gear, when the rack moves, the rack drives the rotating shaft to rotate; the belt pulley and the steel rope wheel which are arranged on the rotating shaft can rotate along with the rotating shaft; the rotating steel rope wheel drives the steel rope wound on the outer circular surface of the steel rope wheel to move, the steel rope wheel on the inner side of the other guardrail shell is driven to rotate while moving, the belt pulley mounted on the steel rope wheel is driven to rotate while rotating, and the steel rope moves the arc-shaped part of the elastic strip connected with the steel rope from the through hole in the guardrail plate to the position between two adjacent guardrail plates while moving, so that the shape of the guardrail unit is changed; the belt pulley rotates and simultaneously drives the belt pulley arranged in the adjacent guardrail unit to rotate; thereby driving the rotating shaft in the adjacent guardrail unit to rotate; by analogy, because the rotation direction of the belt transmission adjacent rotating shafts is the same, the rotation direction of the rotating shafts on the same side of the two adjacent guardrails is opposite. The adjacent guardrail units are opposite in shape after being impacted, so that the guardrail is changed into an S shape through transmission of the structure on the inner side of the guardrail shell when the guardrail is impacted, and the anti-collision effect is achieved. When the impact force is small, all the guardrails are not changed into bow shapes, and the railings cannot be knocked down and far due to the friction between the guardrail bases arranged on the lower sides of the guardrail shells and the ground, the friction between the guardrail plate bases arranged on the lower sides of the guardrail plates and the ground and the traction of other adjacent guardrails; after the collision is finished, the volute spiral spring arranged on the inner side of the railing shell can provide restoring force for the rotating shaft and artificially apply pressure to the deformed guardrail unit; the rotating shaft pulls the elastic strip back to the through hole on the guardrail plate from the gap between the two guardrail plates through the steel rope in the rotating process; thereby restoring the guardrail unit to the original shape.

When the impact force is small, in the design, the original linear state is expected to be maintained between the guardrail plates 6, and the guardrail units 3 swing at a certain angle, so that the collided guardrail is dragged by the non-collided guardrail, the swing angle between the guardrail units 3 is gradually reduced along with the direction angle far away from the collided guardrail units 3 by the designed leaf spring 16, and the design can weaken the triggered resistance of the trigger plate 14, so that the adjacent guardrail units 3 can be smoothly deformed; the angle formed between the guardrail units 3 can cause the adjacent belt pulleys 17 between the guardrail units 3 to mutually rotate at a small angle, and the steel rope 18 can be inevitably moved in a small displacement, so that the two ends of the middle straightening part of the designed elastic strip 31 span between the two guardrail plates 6, the length of the part of the straightening part positioned in the guardrail plates 6 is greater than the distance of the small displacement movement of the steel rope 18, and the arc part can not influence the guardrail plates 6; in the elastic strip 31 designed in the invention, the length of the straightened elastic strip 31 positioned in the through hole of the guardrail plate 6 is the same as that of the straightened elastic strip 31 positioned in the gap between the adjacent guardrail units 3, so when the steel rope 18 pulls the elastic strip 31 to move, the arched elastic strip 31 cannot be pulled out of the through hole of the guardrail plate 6 due to insufficient force.
When the arcuate resilient strip 31 is subjected to a large force, i.e. a sufficient force for a car crash, the straightened portion will be pulled completely out of the through hole of the guardrail plate 6 and the arcuate portion will be pulled to the gap between two adjacent guardrail units 3, thereby bringing the guardrail units 3 into an arcuate shape, as shown in fig. 16.
The specific implementation scheme is as follows: when the guardrail is in a normal state, the elastic strip 31 is positioned in the through hole on the guardrail plate 6, and the elastic strip 31 positioned between the gaps of the two guardrail plates 6 is in a straightening state; when an automobile running on a road sideslips and collides with a guardrail arranged in the middle of the road and the impact force of the automobile to the guardrail is large, an engine hood of the automobile collides with the collision plate 2; when the impact plate 2 is subjected to the impact force of the automobile, a pushing force is applied to the trigger plate 14 arranged on one side of the impact plate 2; under the action of thrust, the trigger plate 14 moves towards the inner side of the trigger plate hole 27 through the matching of the guide block 30 and the guide groove 28, and the trigger plate 14 drives the rack 12 arranged on the inner side to move towards the inner side of the trigger plate hole 27 while the trigger plate 14 moves; since the rack 12 is meshed with the transmission gear 13, when the rack 12 moves, the rack 12 drives the rotating shaft 15 to rotate; the belt pulley 17 and the steel cable wheel 22 arranged on the rotating shaft 15 can rotate along with the rotating shaft; the rotating cable wheel 22 will move the cable 18 wound on its outer circumferential surface, the cable 18 will move and simultaneously rotate the cable wheel 22 on the inner side of the other guardrail housing 1, and simultaneously rotate the pulley 17 mounted thereon, as shown in fig. 15, the cable 18 will move and move the arc-shaped part of the elastic strip 31 connected with the cable 18 from the through hole in the guardrail plate 6 to between two adjacent guardrail plates 6, changing the shape of the guardrail unit 3; the belt pulley 17 rotates and simultaneously drives the belt pulley 17 arranged in the adjacent guardrail unit 3 to rotate; thereby driving the rotating shaft 15 in the adjacent guardrail unit 3 to rotate; by analogy, because the rotation directions of the belt 4 driving the adjacent rotating shafts 15 are the same, the rotation directions of the rotating shafts 15 on the same side of the two adjacent guardrails are opposite. The adjacent guardrail units 3 are opposite in shape after being impacted, so that the guardrail is changed into an S shape through the transmission of the structure on the inner side of the guardrail shell 1 when the guardrail is impacted, and the effect of preventing the guardrail from falling is achieved. When the impact force is small, all the guardrails are not changed into bow shapes, and at the moment, the railings cannot be knocked down and knocked far due to the friction between the railing base 7 arranged on the lower side of the railing shell 1 and the ground, the friction between the guardrail plate base 5 arranged on the lower side of the guardrail plate 6 and the ground and the traction of other adjacent guardrails; after the collision is finished, the spiral spring 21 arranged on the inner side of the guardrail shell 1 can provide restoring force for the rotating shaft 15 and artificially press the deformed guardrail unit 3; the rotating shaft 15 pulls the elastic strip 31 back to the through hole on the guardrail plate 6 from the gap between the two guardrail plates 6 through the steel rope 18 during rotation; thereby restoring the guardrail unit 3 to its original shape.
