Description

Technical Field

[0001] This utility model relates to the field of crash barrier technology, specifically a modular buffer-type road and bridge crash barrier. Background Technology

[0002] Road and bridge crash barriers are facilities used to protect the safety of roads, bridges, and other traffic infrastructure. They are typically located on both sides of roads or bridges as a passive safety measure to reduce the damage to vehicles and pedestrians in collisions. Road and bridge crash barriers are generally made of materials such as steel, aluminum, or concrete, and are structurally robust with a certain degree of elasticity, capable of absorbing impact forces and mitigating the consequences of accidents during vehicle collisions.

[0003] A road and bridge crash barrier with announcement number CN221297584U uses a rotating buffer cylinder to buffer the impact of low-speed impacts, reducing the deformation of the guardrail posts in low-speed collisions and lowering the maintenance costs after the guardrail posts are deformed in low-speed collisions.

[0004] There are still some shortcomings in its use. The impact buffering method is relatively simple, which reduces the anti-collision effect of the guardrail and makes the guardrail less practical and protective. When the guardrail is impacted, it will be damaged and the service life of the guardrail will be reduced. Therefore, we propose a modular buffer road and bridge anti-collision guardrail.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] For examples, please refer to Figures 1-4 This utility model provides a technical solution: A modular buffer-type road and bridge anti-collision guardrail includes a base plate 1, a fixing plate 3 fixedly connected to the top of the base plate 1, a guardrail plate 4 fixedly connected to the top of the fixing plate 3, a slot 10 provided in the fixing plate 3, a side plate 5 provided on the side of the fixing plate 3, an insert rod 9 fixedly connected to the side of the side plate 5, the insert rod 9 being opposite to the slot 10, the insert rod 9 extending into the slot 10 and inserting into the slot 10, a side groove 19 provided in the side plate 5, a movable plate 12 slidably connected in the side groove 19, a connecting spring 13 fixedly connected between the movable plate 12 and the side groove 19, a damping rod 14 provided in the connecting spring 13, the two ends of the damping rod 14 being fixedly connected to the movable plate 12 and the side groove 19 respectively, and a circular groove 17 provided in the side plate 5.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a rubber ball 18 is fixedly connected inside the circular groove 17. A rectangular plate 6 is fixedly connected to the side of the side plate 5 through a sponge adhesive pad 15. When the entire mechanism is impacted, the impact is initially buffered by the elastic force of the rubber plate 8. Then, under the hinge action of the rotating rod 11, the moving plate 12 is moved, so that the moving plate 12 and the connecting spring 13 abut together, which can buffer the impact again. Then, the impact is further buffered by the abutting action of the circular plate 16 against the rubber ball 18, improving the buffering effect of the entire guardrail mechanism during use. A circular plate 16 is fixedly connected to the side of the rectangular plate 6. The circular plate 16 is opposite to the circular groove 17 and abuts against the rubber ball 18. The circular plate 16 is slidably connected to the circular groove 17. An adhesive plate 7 is fixedly connected to the side of the rectangular plate 6. A rubber plate 8 is fixedly connected to the side of the adhesive plate 7. The cross-sectional area of ​​the rubber plate 8 and the rectangular plate 6 is the same.

[0021] The system can provide multiple buffers against impacts to the guardrail panel 4 under the elastic force of the rubber plate 8, connecting spring 13, sponge pad 15, and rubber ball 18, thereby preventing damage to the guardrail, improving its protective effect, and extending its service life.

[0022] In this embodiment, as Figure 3 and Figure 4 As shown, four fastening bolts 2 are rotatably connected inside the base plate 1. The four fastening bolts 2 are respectively located at the bottom corner of the base plate 1. The shape of the insertion rod 9 and the slot 10 are both pentagonal. The material of the insertion rod 9 is stainless steel. A rotating rod 11 is provided between the movable plate 12 and the rectangular plate 6. The two ends of the rotating rod 11 are respectively hinged to the rectangular plate 6 and the movable plate 12. There are two fixed plates 3. The two fixed plates 3 are respectively located on both sides of the guardrail plate 4.

[0023] The side plate 5 can be detachably fixed to the side of the fixing plate 3 through the insertion of the rod 9 and the slot 10, which improves the convenience of the entire guardrail mechanism when carrying it.

[0024] The working process of this utility model is as follows: When the modular buffer road and bridge anti-collision guardrail designed in this scheme is in operation, the fastening bolt 2 is rotated so that the bottom of the fastening bolt 2 rotates into the ground. Then, through the insertion of the insertion rod 9 into the slot 10, the side plate 5 is fixed to the side of the fixed plate 3. When the entire mechanism is impacted, the impact is initially buffered by the elastic force of the rubber plate 8. Then, under the hinge action of the rotating rod 11, the moving plate 12 is moved, so that the moving plate 12 and the connecting spring 13 abut together, which can buffer the impact again. Then, through the abutment action of the round plate 16 against the rubber ball 18, the impact can be further buffered, improving the buffering effect of the entire guardrail mechanism during use. When the entire mechanism is not in use, the insertion rod 9 is pulled to separate the insertion rod 9 from the slot 10, so that it can be disassembled and the entire mechanism can be carried.
