Multi-angle protective anti-collision guardrail

Abstract

The multi-angle protective anti-collision guardrail comprises a base and a top seat, a first arc-shaped plate and a second arc-shaped plate are fixedly connected between the base and the top seat, and a polyurethane foam anti-collision pad is fixedly connected to the arc-shaped protruding face of the first arc-shaped plate; a first rubber cushion block and a second rubber cushion block which are symmetrically distributed are arranged between the first arc-shaped plate and the second arc-shaped plate, and a first supporting rod, a second supporting rod and a third supporting rod which are symmetrically distributed are fixedly connected between the first arc-shaped plate and the second arc-shaped plate; when being impacted by external force, the air holes in the polyurethane foam anti-collision pad can be compressed and deformed to absorb a large amount of energy, and after the impact force is conducted to the first arc-shaped plate, the impact force is dispersed to a larger area along the arc surface instead of being concentrated on one point due to the arc shape, so that the impact force borne by the local part is reduced, and the service life of the anti-collision pad is prolonged. The risk that the guardrail is crashed is reduced, bending and deformation can be better resisted, and the situation that a vehicle breaks through the guardrail and falls off from a bridge is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of bridge guardrails, and in particular to a multi-angle protection and anti-collision guardrail. Background Art

[0002] Bridge guardrails are guardrails installed on bridges. Their purpose is to prevent uncontrolled vehicles from crossing the bridge, preventing vehicles from breaking through, passing under, or climbing over the bridge, and beautifying the bridge structure. However, existing technologies have the following shortcomings when used:

[0003] Existing bridge guardrails are basically composed of multiple horizontal bars and vertical bars, and their overall anti-collision effect is poor. When a vehicle hits the guardrail, the guardrail may undergo a large deformation and break, causing the vehicle to break through the guardrail and fall from the bridge. In actual use, the protection effect is average.

[0004] Therefore, a multi-angle protection anti-collision guardrail is urgently needed to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to address the problem that the existing bridge guardrails are basically composed of multiple horizontal bars and vertical bars, and their overall anti-collision effect is poor. When a vehicle hits the guardrail, the guardrail may be greatly deformed and broken, causing the vehicle to break through the guardrail and fall from the bridge. In actual use, the protective effect is generally poor.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A multi-angle protection anti-collision guardrail is used to improve the above problems.

[0008] The specific application is as follows:

[0009] A multi-angle protective anti-collision guardrail includes a base and a top seat, a first curved plate and a second curved plate are fixedly connected between the base and the top seat, a polyurethane foam anti-collision pad is fixedly connected to the curved convex surface of the first curved plate, a first rubber pad and a second rubber pad are symmetrically distributed between the first curved plate and the second curved plate, a first support rod, a second support rod and a third support rod are fixedly connected between the first curved plate and the second curved plate, and the interior of the polyurethane foam anti-collision pad has a porous structure.

[0010] As a preferred technical solution of the present application, the base is provided with a first mounting hole and a second mounting hole that are symmetrically distributed, and the first mounting hole and the second mounting hole have the same specifications.

[0011] As a preferred technical solution of the present application, symmetrically distributed fluorescent panels are fixedly connected to the front side of the top seat.

[0012] As a preferred technical solution of the present application, the first curved plate and the second curved plate are symmetrically distributed about the transverse center line of the base.

[0013] As a preferred technical solution of the present application, the front and rear end surfaces of the first rubber pad are respectively in contact with the first curved plate and the second curved plate.

[0014] As a preferred technical solution of the present application, the top seat is located directly above the base seat.

[0015] As a preferred technical solution of the present application, the front and rear end surfaces of the second rubber pad are respectively in contact with the first curved plate and the second curved plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] When a vehicle collides with the guardrail, the vehicle will first come into contact with the polyurethane foam anti-collision pad. The pores in the polyurethane foam anti-collision pad will be compressed and deformed, thereby absorbing a large amount of energy, which can significantly reduce the impact force generated by the collision and protect the safety of the vehicle and passengers. At the same time, when the impact force is transmitted to the first curved plate, the curved shape disperses the impact force along the curved surface to a larger area, and can disperse the impact force in multiple directions instead of concentrating it on one point, reducing the local impact force and the risk of the guardrail being damaged. The structure is relatively more stable and can better resist bending and deformation. The two first rubber pads and the two second rubber pads It can absorb part of the impact force generated again. At the same time, through the coordinated use with the second curved plate, the first support rod, the second support rod and the third support rod, the first curved plate can convert the pressure into tension distributed along the curved plate when subjected to impact force, thereby improving the overall strength of the guardrail and preventing vehicles from breaking through the guardrail and falling from the bridge. It solves the problem that the existing bridge guardrails in the prior art are basically composed of multiple horizontal bars and vertical bars, and their overall anti-collision effect is poor. When a vehicle hits the guardrail, the guardrail may be greatly deformed and broken, causing the vehicle to break through the guardrail and fall from the bridge, and the protection effect is general during actual use.

[0030] Example:

[0031] like Figure 1-4 As shown, a multi-angle protective anti-collision guardrail proposed in this embodiment includes a base 1 and a top seat 2, a first curved plate 3 and a second curved plate 4 are fixedly connected between the base 1 and the top seat 2, and a polyurethane foam anti-collision pad 5 is fixedly connected to the curved convex surface of the first curved plate 3. When a vehicle collides with this guardrail, the vehicle will first contact the polyurethane foam anti-collision pad 5. When impacted by external force, the pores in the polyurethane foam anti-collision pad 5 will be compressed and deformed, thereby absorbing a large amount of energy, which can significantly reduce the impact force generated by the collision and protect the safety of the vehicle and passengers. A symmetrically distributed first rubber pad 6 and a second rubber pad 7 are provided between the first curved plate 3 and the second curved plate 4. When the impact force is transmitted to the first curved plate 3, the arc shape causes the impact force to be dispersed to a larger area along the arc surface, which can be Dispersing the impact force in multiple directions instead of concentrating it on one point can reduce the local impact force and lower the risk of the guardrail being damaged. The structure is relatively more stable and can better resist bending and deformation. The first curved plate 3 and the second curved plate 4 are fixedly connected with a symmetrically distributed first support rod 8, a second support rod 9 and a third support rod 10. The two first rubber pads 6 and the two second rubber pads 7 can absorb part of the impact force again. The polyurethane foam anti-collision pad 5 has a porous structure inside. Through the use of the second curved plate 4, the first support rod 8, the second support rod 9 and the third support rod 10, the first curved plate 3 can convert the pressure into tension distributed along the curved surface when subjected to impact force, thereby improving the overall strength of the guardrail and preventing vehicles from breaking through the guardrail and falling off the bridge.

[0032] like Figure 3 As shown, the base 1 is provided with a symmetrically distributed first mounting hole 11 and a second mounting hole 12. The first mounting hole 11 and the second mounting hole 12 have the same specifications. The staff fixes the base 1 on the bridge by using multiple fixing screws in conjunction with the first mounting hole 11 and the second mounting hole 12.

[0033] like Figure 1 As shown, the front of the top seat 2 is fixedly connected with symmetrically distributed fluorescent plates 13. The fluorescent plates 13 can emit a certain amount of light at night, which has a certain warning effect on passing vehicles.

[0034] like Figure 3 As shown, the first curved plate 3 and the second curved plate 4 are symmetrically distributed about the transverse center line of the base 1 .

[0035] like Figure 3 As shown, the front and rear end surfaces of the first rubber pad 6 are respectively fitted with the first curved plate 3 and the second curved plate 4.

[0036] like Figure 1 As shown, the top seat 2 is located directly above the base seat 1 .

[0037] like Figure 3 As shown, the front and rear end surfaces of the second rubber pad 7 are respectively fitted with the first curved plate 3 and the second curved plate 4. The two first rubber pads 6 and the two second rubber pads 7 can absorb part of the impact force generated.

[0038] Specifically, when the multi-angle protection anti-collision guardrail is in use: the staff uses a plurality of fixing screws to match the first mounting hole 11 and the second mounting hole 12 to fix the base 1 on the bridge. When a vehicle hits the guardrail, the vehicle will first contact the polyurethane foam anti-collision pad 5. When impacted by external force, the pores in the polyurethane foam anti-collision pad 5 will be compressed and deformed, thereby absorbing a large amount of energy, which can significantly reduce the impact force generated by the collision and protect the safety of the vehicle and the driver and passengers. At the same time, when the impact force is transmitted to the first curved plate 3, the curved shape causes the impact force to be dispersed to a larger area along the curved surface, which can be Dispersing the impact force in multiple directions instead of concentrating it on one point can reduce the local impact force and lower the risk of the guardrail being damaged. The structure is relatively more stable and can better resist bending and deformation. The two first rubber pads 6 and the two second rubber pads 7 can absorb part of the impact force generated again. At the same time, through the coordinated use with the second curved plate 4, the first support rod 8, the second support rod 9 and the third support rod 10, the first curved plate 3 can convert the pressure into tension distributed along the curved surface when subjected to impact force, thereby improving the overall strength of the guardrail and preventing vehicles from breaking through the guardrail and falling off the bridge.
