DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0032] like Figure 1-7As shown, the bridge anti-collision guardrail provided by the utility model includes: two columns 1, the columns 1 are installed at the shoulder positions on both sides of the bridge, a first protective frame 2 is installed between the columns 1, a first buffer mechanism is installed on one side of the first protective frame 2, the first buffer mechanism includes a second protective frame 3, the second protective frame 3 and the first protective frame 2 are both I-shaped, and the second protective frame 3 is installed with a plurality of buffer wheels 4 arranged in an arc; the buffer wheel 4 includes a rotating shaft 15, both ends of the rotating shaft 15 are connected to the second protective frame 3, and the outer layer of the rotating shaft 15 is provided with a latex layer 17. When in use, when a vehicle has a slight side collision with the guardrail, the vehicle first hits the buffer wheel 4. Since the outermost layer of the buffer wheel 4 is a soft latex layer 17, it can greatly absorb energy and protect the vehicle surface, and the plurality of buffer wheels 4 arranged in an arc rotate when hit by the vehicle, guide the vehicle to change direction, gradually reduce the vehicle impact angle, and thereby reduce the possibility of vehicle damage, especially in the case of slight collision caused by small-angle collision, the latex layer 17 can effectively protect the vehicle paint.

[0033] By arranging the upright column 1, the first protective frame 2, the second protective frame 3 and a plurality of buffer wheels 4, and arranging the latex layer 17 on the buffer wheel 4, it is possible to guide the vehicle to change its direction of travel, reduce the impact angle of the vehicle, and reduce the loss of the vehicle when the vehicle collides. In addition, when a minor collision occurs, the latex layer 17 is deformed and absorbs energy, which can effectively protect the vehicle paint and reduce the loss of the vehicle.

[0034] Embodiment 2:

[0035] like Figure 2-3 As shown, a plurality of cross grooves 5 are provided on the first protective frame 2, and a plurality of connectors 6 of rectangular column structures are installed on one side of the back of the second protective frame 3. An elastic component 7 is provided in the cross groove 5. The connector 6 is inserted into the cross groove 5 and connected to the elastic component 7. When in use, the second protective frame 3 and the first protective frame 2 are elastically connected through the joint action of the connector 6 and the elastic component 7. Therefore, when a strong impact occurs, the energy absorption of the elastic component 7 can effectively reduce the impact force, thereby reducing the damage to the vehicle and the guardrail.

[0036] By providing the cross groove 5, the connector 6 and the elastic component 7, the second protection frame 3 is elastically connected to the first protection frame 2, so that the energy of the impact can be absorbed and the damage to the vehicle and the guardrail can be reduced.

[0037] Embodiment 3:

[0038] like Figure 4As shown, the elastic component 7 includes four elastic components arranged in a cross, and the elastic components include a first connecting plate 8 and a second connecting plate 9. A spring 10 is installed between the first connecting plate 8 and the second connecting plate 9. The first connecting plate 8 is connected to the inner wall of the cross groove 5. A hinge plate 11 is installed on the second connecting plate 9. One side of the hinge plate 11 is hinged to the connecting head 6, and then the second connecting plate 9 is connected to the connecting head 6 through the hinge plate 11. When impact occurs, the connecting head 6 moves into the cross groove 5, and then the first connecting plate 8 moves when passing through the hinge plate 11, thereby deforming the spring 10 to absorb energy.

[0039] By providing an elastic component including a first connecting plate 8, a second connecting plate 9 and a spring 10, and utilizing four elastic components arranged in a cross to form an elastic component 7, the connecting head 6 can obtain relatively stable elastic support in the cross groove 5, and can absorb energy through the deformation of the spring 10, thereby reducing the damage to the vehicle and the guardrail caused by the impact force.

[0040] Embodiment 4:

[0041] like Figure 5 As shown, a guide tube 12 is installed on the first connecting plate 8, and a guide head 13 is installed on the second connecting plate 9. The guide head 13 is inserted into the guide tube 12, and the spring 10 is sleeved on the guide head 13 and the guide tube 12. When in use, when an impact occurs, the connecting head 6 moves into the cross groove 5, and the second connecting plate 9 is moved along the axial direction of the guide head 13 through the hinged plate 11, thereby compressing the spring 10.

[0042] By providing the guide tube 12 and the guide head 13 , the movement of the second connecting plate 9 can be guided.

[0043] Embodiment 5:

[0044] like Figure 6 As shown, a grid-shaped structural layer 16 is provided between the rotating shaft 15 and the latex layer 17. The structural layer 16 is made of aluminum alloy or nylon material. When in use, when the impact force is large, it is difficult to effectively buffer. At this time, the structural layer 16 can be deformed or broken by the impact, and absorb energy through its own deformation or fragmentation, thereby reducing the damage to the vehicle caused by the impact.

[0045] By providing a grid-like structural layer 16 between the rotating shaft 15 and the latex layer 17, the structural layer 6 can be deformed or broken to absorb energy, thereby reducing the degree of damage to the vehicle caused by the collision.

[0046] Embodiment 6:

[0047] like Figure 7As shown, a diagonal support column 14 is installed on the back of the column 1. When in use, the diagonal support column 14 is fixed to the bridge deck by bolts to provide auxiliary support for the column 1, thereby improving the stability of the column 1 and further improving the stability of the guardrail.

[0048] By installing the diagonal support column 14 on the back side of the column 1, the stability of the guardrail can be improved.

[0049] Working principle: When in use, when a vehicle has a slight side collision with the guardrail, the vehicle first hits the buffer wheel 4. Since the outermost layer of the buffer wheel 4 is a soft latex layer 17, it can greatly absorb energy and protect the vehicle surface. The multiple buffer wheels 4 arranged in an arc are rotated by the impact of the vehicle, guiding the vehicle to change direction, gradually reducing the impact angle of the vehicle, and thereby reducing the possibility of damage to the vehicle, especially in the case of slight collisions caused by small-angle impacts. The latex layer 17 of sufficient thickness can effectively protect the vehicle paint to a great extent.
