DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1 to Figure 5 As an embodiment of the utility model, a safety guardrail for road and bridge construction includes a column 1 and a connecting groove 2 opened on the outer wall of the column 1, a safety guardrail body 3 is arranged between two adjacent columns 1, and two safety guardrail bodies 3 are arranged. A rotating connection component is arranged on the wall surface of the safety guardrail body 3 opposite to the column 1, and a telescopic buffer component is arranged between the two safety guardrail bodies 3. The rotating connection component is used to rotatably connect the safety guardrail body 3 to the column 1, and the telescopic buffer component is used to connect the safety guardrail body 3 between two adjacent columns 1, and the telescopic buffer component is retractable, that is, the telescopic buffer component can alleviate the force impacting the safety guardrail body 3.

[0024] In this embodiment, when a vehicle on the road hits the safety guardrail body 3 between two adjacent columns 1, the impact force of the two safety guardrail bodies 3 between the two adjacent columns 1 caused by the impact of the vehicle will rotate on the columns 1 through the rotating connection assembly, and the safety guardrail body 3 will pull the telescopic buffer assembly during the rotation process, and the telescopic buffer assembly will alleviate the force of the impact on the safety guardrail body 3 between the two adjacent columns 1 during the pulling process. The force of the vehicle hitting the safety guardrail body 3 can be alleviated by setting the rotating connection assembly and the telescopic buffer assembly, which can not only improve the toughness of the safety guardrail body 3, thereby reducing the phenomenon of the safety guardrail body 3 being broken, but also reduce the inertial impact caused by the impact of the vehicle, thereby reducing the damage to the owner caused by the inertia of the vehicle being hit.

[0025] As a further solution of the utility model, the rotating connection assembly includes a first connecting block 4 sleeved in the connecting groove 2 and a first connecting plate 5 fixedly arranged on the safety guardrail body 3, a second connecting plate 6 is fixedly arranged on the first connecting block 4, the positions of the first connecting plate 5 and the second connecting plate 6 correspond to each other, and the corresponding first connecting plate 5 and the second connecting plate 6 are connected by connecting screws.

[0026] Among them, a ring is fixedly set in the first connecting block 4, and a groove is opened in the connecting slot 2. The ring on the first connecting block 4 is sleeved in the groove in the connecting slot 2. The setting of the ring and the groove can reduce the friction between the first connecting block 4 and the connecting slot 2, thereby making the rotation of the first connecting block 4 on the connecting slot 2 smoother. The setting of the connecting screws, the first connecting block 4, and the second connecting plate 6 can not only connect the safety guardrail body 3 with the column 1, but also make it simple and convenient to remove the damaged safety guardrail body 3 from the column 1.

[0027] As a further solution of the utility model, the telescopic buffer assembly includes a connecting tube 7 fixedly arranged on a safety guardrail body 3 between two adjacent columns 1 and a second connecting block 8 on another safety guardrail body 3 between two adjacent columns 1, a telescopic spring 9 and an insertion rod 10 are arranged in the connecting tube 7, and the two ends of the telescopic spring 9 in the connecting tube 7 are respectively connected to the bottom end of the inner side of the connecting tube 7 and the insertion rod 10 inserted in the connecting tube 7, a hook 11 is fixedly arranged at one end of the connecting tube 7 away from the telescopic spring 9, and the hook 11 is hung on the second connecting block 8 on the safety guardrail body 3 corresponding to the position of the hook 11, a guide groove 12 is opened in the connecting tube 7, and a guide block 13 is fixedly arranged on the outer wall surface of the insertion rod 10, and the guide block 13 is located in the guide groove 12 on the inner side of the connecting tube 7, and the diameter of the guide block 13 is adapted to the diameter of the guide groove 12.

[0028] In this embodiment, when a vehicle on the road hits the safety guardrail body 3 between two adjacent columns 1, the two safety guardrail bodies 3 between the two adjacent columns 1 will be rotated on the column 1 through the first connecting block 4 by the impact force of the vehicle collision. During the rotation, the safety guardrail body 3 will pull the plug rod 10 through the hook 11. During the pulling process, the plug rod 10 will pull the telescopic spring 9 in the connecting tube 7. The telescopic spring 9 is stretched by the force. During the process of increasing the distance between the two safety guardrail bodies 3 between the two adjacent columns 1, a part of the inertia generated by the vehicle collision will be relieved, and the other part will be transmitted to the column 1 through the safety guardrail body 3. The column 1 will then transmit the force to the ground, thereby intercepting the vehicle hitting the safety guardrail body 3. By setting the rotating connection component, the safety guardrail body 3 can be rotated on the column 1, thereby improving the toughness of the safety guardrail body 3 and making the safety guardrail body 3 less likely to be damaged. The setting of the telescopic buffer component allows a certain adjustable distance between two adjacent safety guardrail bodies 3, which can alleviate the force of the device on the safety guardrail body 3 and reduce the phenomenon of the safety guardrail body 3 being damaged.

[0029] As a further solution of the utility model, a support reinforcement assembly is provided on the column 1, and the support reinforcement assembly includes a reinforcement cross bar 14 arranged on the column 1, and a third connecting plate 15 is provided between the reinforcement cross bar 14 and the column 1, and the third connecting plate 15 is used to fix the column 1 and the reinforcement cross bar 14 together, and a support reinforcement plate 16 is provided on the reinforcement cross bar 14, and the end of the support reinforcement plate 16 away from the reinforcement cross bar 14 is connected to the column 1, and a positioning hole is opened on the reinforcement cross bar 14, and a plurality of positioning holes are provided in sequence.

[0030] In this embodiment, when the column 1 needs to be fixed to the ground, the reinforcing cross bar 14 is first placed at the bottom end of the column 1, and then the reinforcing cross bar 14 is fixed to the column 1 through the third connecting plate 15. After the column 1 and the reinforcing cross bar 14 are fixedly connected together, the supporting reinforcing plate 16 is placed between the column 1 and the reinforcing cross bar 14, and the two ends of the supporting reinforcing plate 16 are respectively fixedly connected to the column 1 and the reinforcing cross bar 14. The support ground of the column 1 can be improved by setting the supporting reinforcement assembly, thereby improving the firmness of the column 1 fixed to the ground.

[0031] As a further solution of the utility model, the safety guardrail body 3 includes a fixed frame and a fence net fixedly arranged in the fixed frame, the connecting tube 7 and the second connecting block 8 are connected to the outer wall surface of the fixed frame, and a support plate 17 is fixedly arranged at the top of the column 1.
