[0027] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] The following is combined with Figure 1-6 The present invention is further described.

[0030] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a bridge anti-collision guardrail with a buffer structure.

[0031] Example 1

[0032] The specific technical solution includes a frame 1, a rotating sleeve 3, and a shell 5.

[0033] In this application, the rack 1 is provided with multiple groups, and the backs of the racks 1 are fixedly connected to each other by steel plates, and anti-collision columns 2 are rotatably mounted on the racks 1;

[0034] The specific rotation installation is as follows: a mounting groove 12 is provided on the frame 1, and a rotating seat 13 is rotatably installed in the mounting groove 12. The rotating seat 13 is fixedly connected to the anti-collision column 2, so the rotation installation of the anti-collision column 2 is realized. The purpose is to be able to rotate and buffer when it is hit. A fixed block 7 is fixedly installed on the outside of the anti-collision column 2, and a conical spring 8 is fixedly installed on the outside of the fixed block 7. The purpose of this arrangement is to allow the conical spring 8 to collide with the frame 1 when the anti-collision column 2 is hit and rotated. Through the compression of the conical spring 8, the generated impact can be further buffered.

[0035] The above technical means are further refined as follows: the rotating sleeve 3 is rotatably installed on the outside of the anti-collision column 2, and the shell 5 is fixedly installed on the frame 1. The shell 5 is a circular structure, and the outside of the rotating sleeve 3 is fixedly connected with multiple groups of buffer blocks 4. The buffer blocks 4 are made of rubber or silicone and are used for buffering.

[0036] At the same time, a turntable 14 is rotatably installed in the shell 5, and a plurality of groups of semicircular protrusions 19 of different diameters are fixedly installed on the outside of the turntable 14 to resist the spring sheet 17. A winding roller 15 is also fixedly installed on the turntable 14, and a second pull rope 16 is wound around the winding roller 15. The second pull rope 16 is fixedly connected to the rotating sleeve 3. Specifically, the turntable 14 is rotatably installed in the shell 5 through the rotating shaft, and a second torsion spring is also sleeved on the outside of the rotating shaft. The two ends of the second torsion spring are fixedly engaged with the turntable 14 and the inner wall of the shell 5 respectively, so that torque reset is achieved.

[0037] When the tangential impact is applied, the rotating sleeve 3 rotates, so that the second pull rope 16 can be wound, and the second pull rope 16 drives the winding roller 15 to rotate, and the winding roller 15 drives the turntable 14 to rotate counterclockwise. Figure 3 As shown, the turntable 14 drives the semicircular protrusion 19 to resist the spring sheet 17. Since the radius of the semicircular protrusion 19 gradually increases in the clockwise direction, the buffering effect becomes better and better when the turntable 14 rotates counterclockwise.

[0038] In order to cooperate with the rotation buffer of the turntable 14, a first buffer component is set up. The first buffer component is arranged in the shell 5 and is used to provide buffering when the rotating sleeve 3 rotates. The first buffer component is a plurality of groups of spring leaves 17 fixedly installed in the shell 5. A plurality of groups of strong springs 20 are fixedly connected between the spring leaves 17 and the inner wall of the shell 5.

[0039] Further details are as follows: the radius of the semicircular protrusion 19 gradually increases in the clockwise direction. When subjected to a tangential impact, the rotating sleeve 3 rotates, so that the second pull rope 16 can be wound. The second pull rope 16 drives the winding roller 15 to rotate, and the winding roller 15 drives the turntable 14 to rotate counterclockwise. Figure 3As shown, the turntable 14 drives the semicircular protrusion 19 to resist the spring sheet 17. Since the radius of the semicircular protrusion 19 gradually increases in the clockwise direction, the buffering effect becomes better and better when the turntable 14 rotates counterclockwise.

[0040] Please refer to the following for details

[0041] The device is installed on the side of a bridge or road. When it is hit tangentially, the rotating sleeve 3 rotates, so that the second pull rope 16 can be wound. The second pull rope 16 drives the winding roller 15 to rotate, and the winding roller 15 drives the turntable 14 to rotate counterclockwise. Figure 3 As shown, the turntable 14 drives the semicircular protrusion 19 to resist the spring sheet 17. Since the radius of the semicircular protrusion 19 gradually increases in the clockwise direction, the buffering effect becomes better and better when the turntable 14 rotates counterclockwise.

[0042] Because the first thing that contacts the spring sheet 17 is the semicircular protrusion 19 with a smaller diameter, and then the semicircular protrusion 19 with the largest diameter finally contacts the spring sheet 17, so the contact effect on the spring sheet 17 is the best. By adopting such a gradual approach, the vehicle can be further buffered and protected.

[0043] At the same time, if the vehicle directly collides with the anti-collision column 2, the anti-collision column 2 rotates, and then drives the conical spring 8 to compress the frame 1, thereby further buffering the vehicle.

[0044] Example 2

[0045] This embodiment is different from the first embodiment in that a slot 6 is provided in the frame 1 , and further includes a second buffer assembly, which is disposed in the slot 6 and is used for buffering when the anti-collision column 2 rotates.

[0046] Specifically, the second buffer assembly includes a rotating plate 9, a magnet 21 and a winding disk 11. The rotating plate 9 is rotatably mounted in the slot 6. The rotating plate 9 and the inner wall of the slot 6 are fixedly mounted with magnets 21. The magnets 21 are arranged so that the same poles repel each other. The winding disk 11 is rotatably mounted on the outside of the frame 1 through a rotating rod. The outside of the rotating rod is also sleeved with a first torsion spring. The first pull rope 10 is wound around the winding disk 11, and the first pull rope 10 is fixedly connected to the rotating plate 9.

[0047] Therefore, the following buffering effect will be produced during the collision. If it directly hits the anti-collision column 2, the anti-collision column 2 will rotate, and then drive the conical spring 8 to rotate the rotating plate 9. The magnet 21 is set to repel each other with the same poles, so the rotation can be further buffered. When the rotating plate 9 rotates, the first pull rope 10 will be pulled, and the first pull rope 10 will rotate the winding disk 11. The winding disk 11 allows the first torsion spring to twist and bear the force, thereby further increasing the buffering effect.

[0048] Example 3

[0049] This embodiment is different from the second embodiment in that the second buffer component is a rubber bag fixedly disposed in the notch 6 and filled with a non-Newtonian fluid.

[0050] The conical spring 8 can also provide buffering protection when impacting the non-Newtonian fluid.

[0051] Example 4

[0052] This embodiment is different from the first embodiment in that an arc-shaped buffering protrusion 18 is fixedly connected to the outside of the spring sheet 17 for cooperating with the semicircular protrusion 19 to increase buffering damping and enhance the buffering effect.

[0053] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
