Description

Technical Field

[0001] The invention relates to the technical field of bridge guardrails, in particular to an anti-collision guardrail for bridges used in civil engineering. Background Art

[0002] Bridges are often built over dangerous areas such as rivers and valleys. Vehicles may lose control due to sudden tire pressure loss, driver misoperation, or emergency braking during driving. Anti-collision guardrails can absorb part of the collision energy, reduce the impact inside the vehicle, and reduce the damage to passengers and drivers. The bridge anti-collision guardrail in the prior art is composed of beams and railings erected between multiple pile foundations cast on the bridge deck, and buffer materials such as polyurethane foam or rubber are arranged on the side of the beams and railings facing the road. The elasticity of the buffer material is used to slow down the speed change of the vehicle during the collision, thereby reducing the impact force. In the actual application of the bridge anti-collision guardrail, due to the limited thickness of the buffer material and its small deformation, the effect of absorbing and dispersing the impact energy of the car is not good, it is difficult to form an effective buffering effect, and the use effect is poor. In addition, when the guardrail is hit, it may deform and break, aggravating the damage to the car and posing a greater safety hazard. Therefore, the present application provides a bridge anti-collision guardrail for civil engineering. Summary of the invention

[0003] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a bridge anti-collision guardrail for civil engineering. The horizontal position of the buffer component on the guardrail can be staggered with the casting position of the pile foundation, and protrude a certain distance toward the inside of the road. On the basis of ensuring the absorption and dispersion of the energy generated during the car collision, the safety hazards caused by deformation and fracture of the pile foundation due to vehicle collision are greatly reduced, and the reliability of use is good.

[0004] The technical solution adopted by the present invention to solve the technical problem is: Provided is a bridge anti-collision guardrail for civil engineering, comprising pile foundations, horizontal bars and vertical bars, wherein a plurality of pile foundations, horizontal bars and vertical bars are respectively provided, wherein the horizontal bars are fixedly installed between the plurality of pile foundations, and the vertical bars are fixedly installed between the plurality of horizontal bars; a buffer bar is movably installed on the side of the horizontal bar, a vertical rod is fixedly installed on the buffer bar, and a plurality of air bags are provided on the outer side of the vertical rod; the plurality of vertical bars and the plurality of vertical rods are connected by a separate connecting rod, and the two ends of the connecting rod are rotatably connected to the vertical bar and the vertical rod respectively.

[0005] Furthermore, an articulated seat II is integrally formed on one of the vertical bars, a driving arm is fixedly installed on the end of one of the connecting rods, a linear electric cylinder is rotatably installed on the articulated seat II, a T-shaped seat is fixedly installed on the movable end of the linear electric cylinder, and the T-shaped seat is rotatably connected to the driving arm.

[0006] Furthermore, the buffer fence and the vertical rod are hollow inside and connected to each other, an air pipe is provided on the buffer fence, a valve is installed on the air pipe, and an air guide hole is provided on the inner wall of the vertical rod, and the airbag is connected to the vertical rod through the air guide hole.

[0007] In the present application, an optional technical solution for injecting air into the buffer fence through an air pipe is that a high-pressure gas storage tank is detachably and fixedly mounted on the end of the air pipe.

[0008] In the present application, another optional technical solution for injecting air into the buffer fence through an air pipe is that the end of the air pipe is connected to an air pump through a conduit.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The anti-collision guardrail for bridges used in civil engineering of the present invention adjusts the rotation angle of multiple connecting rods on the vertical rails, and utilizes the elastic deformation capacity of the buffer rails, vertical rods and connecting rods to effectively absorb and disperse the energy generated during the collision of the car, reduce the impact force borne by the vehicle at the moment of collision, and ensure the driving safety of the vehicle on the road; because the buffer component is staggered in horizontal position from the pile foundation and protrudes a distance toward the inner side of the road, it can effectively prevent the vehicle from directly colliding with the pile foundation, and avoid safety hazards caused by pile foundation fracture.

[0010] 2. The anti-collision guardrail for bridges used in civil engineering in the example of the present invention is combined with the monitoring camera on the lane. When the monitoring camera detects that the car is out of control or an accident occurs, the rotation of the connecting rod is controlled to actively adjust the protrusion distance of the buffer bar on the pile foundation and the side of the cross bar, thereby improving the buffering effect on the vehicle, reducing the impact inside the vehicle, and reducing the damage to passengers and drivers.
