AI Technical Summary
The existing rotating barrel material is susceptible to exposure to summer sun, and shortened service life. The road slippage in snowy winter causes vehicle slippage, causing traffic congestion.
The rubber barrel is equipped with a filling cavity to fill sand and gravel, and a metal protective layer is added on the outside. In winter, sand and gravel can be discharged through the discharge component to form a sand and gravel layer that is anti-slip.
Improve the buffering resistance of the rotating barrel body to resist deformation, prevent permanent deformation, ensure vehicle passability, and avoid slippage in snow.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of guardrails, in particular to a road guardrail. Background Art
[0002] Road guardrails mainly play the role of absorbing energy when a vehicle collides, being neither easily damaged nor easily destroyed, and at the same time can play a good protective role for vehicles and drivers and passengers. In order to improve the protection of the guardrail for vehicles, existing ones will install rotating barrels on the guardrail to avoid rigid collisions of vehicles.
[0003] However, the existing rotating barrels are mainly made of elliptical hollow plastics. They are affected by summer exposure and their service life is reduced. Moreover, when the rotating barrels made of hollow plastics are impacted by a vehicle, they will undergo permanent deformation and are not easily restored. At the same time, in winter, when there is snow and the road surface is slippery, especially on the curved road surface, once a vehicle slips or sideslips, it is very easy to cause collisions, resulting in serious traffic congestion. Content of the Utility Model
[0004] In order to solve the above existing problems, the utility model provides a road guardrail.
[0005] The utility model is realized through the following technical solutions:
[0006] A road guardrail includes guardrail brackets arranged at the upper and lower ends of the road side. A number of rotating barrels are installed between the upper and lower guardrail brackets. The rotating barrel includes a rubber barrel body. A filling cavity is arranged inside the rubber barrel body. The filling cavity is filled with sand and gravel. A discharging component is arranged at the lower part of the filling cavity.
[0007] Further optionally, the rotating barrel is rotatably connected to a support column. The upper and lower ends of the support column are fixedly connected to the guardrail bracket through connecting blocks.
[0008] Further optionally, a metal protective layer is coated on the outer side of the rubber barrel body.
[0009] Further optionally, a sand filling port communicating with the filling cavity is opened at the top of the rubber barrel body.
[0010] Further optionally, the discharging component includes a plurality of sand discharging holes opened at the lower part of the rubber barrel body and communicating with the filling cavity. A closing cover is arranged at the lower part of the sand discharging holes. A plurality of rubber plugs for inserting and sealing the sand discharging holes are fixed on the closing cover.
[0011] Further optionally, the closing cover is closely attached to the protective layer at the bottom of the rubber barrel body.
[0012] Compared with the existing technologies, the beneficial effects of the present utility model are as follows: by providing a filling cavity in the rotating barrel of the road guardrail and filling sand and gravel materials that can be discharged through the discharge assembly in the filling cavity, not only can the buffer and anti-deformation capabilities of the rotating barrel be improved, but also road skidding in snowy days can be prevented, ensuring the passing ability of vehicles.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments:
[0018] As Figure 1 , 2 shown, a road guardrail includes guardrail brackets 1 arranged at the upper and lower ends of the road side. A plurality of rotating barrels 4 are installed between the upper and lower guardrail brackets 1. The rotating barrel 4 includes a rubber barrel 5. A filling cavity 7 is arranged inside the rubber barrel 5. Sand and gravel materials 71 are filled in the filling cavity 7. The sand and gravel materials 71 have good cushioning properties to improve the cushioning and anti-deformation capabilities of the rotating barrel 4. A discharge assembly is arranged at the lower part of the filling cavity 7.
[0019] As Figure 1 shown, the rotating barrel 4 is rotatably connected to the support column 3. The upper and lower ends of the support column 3 are fixedly connected to the guardrail bracket 1 through the connecting block 2.
[0020] As Figure 2 shown, a metal protective layer 6 is coated on the outer side of the rubber barrel 5. The metal protective layer 6 can be made of iron sheet with a thickness of 1 - 2 mm to prevent sun exposure and extend the service life of the rubber barrel 5.
[0021] As Figure 2 shown, a sand filling port 8 communicating with the filling cavity 7 is opened at the top of the rubber barrel 5, and the filling cavity 7 is replenished with sand and gravel materials through the sand filling port 8.
[0022] As Figure 2As shown, the discharging assembly includes a plurality of sand discharging holes 9 formed in the lower part of the rubber barrel body 5 and communicating with the filling cavity 7. A closing cover 10 is arranged below the sand discharging holes 9. A plurality of rubber plugs 11 inserted into the sand discharging holes 9 for sealing are fixed on the closing cover 10. By pulling out the rubber plugs 11 of the closing cover 10 from the sand discharging holes 9, the sand and gravel materials are discharged and scattered on the road, avoiding the phenomenon of skidding on the road in snowy days.
[0023] As Figure 2 shown, the closing cover 10 is closely attached to the protective layer 6 at the bottom of the rubber barrel body 5.
[0024] The implementation principle of an embodiment of a road guardrail in this application is as follows:
[0025] A filling cavity 7 is formed inside the rotating barrel body 4 of the road guardrail, and sand and gravel materials 71 are filled in the filling cavity 7. These sand and gravel materials 71 can not only improve the buffering performance against vehicle collisions, but also improve the anti-deformation ability of the rotating barrel body 4, thereby avoiding permanent deformation of the rotating barrel body 4 and ensuring the subsequent use of the rotating barrel body 4.
[0026] When it is easy to skid and sideslip on the road in snowy days in winter, the closing cover 10 of the discharging assembly at the lower part of a plurality of rotating barrel bodies 4 of the nearby guardrail can be opened, so that the plurality of rubber plugs 11 of the closing cover 10 are pulled out from the sand discharging holes 9 of the rotating barrel body 4. In this way, the sand and gravel materials 71 in the filling cavity 7 of the rotating barrel body 4 will be discharged along the sand discharging holes 9, and the staff will sprinkle the discharged sand and gravel materials 71 on the road surface to form a sand and gravel layer 13 (as Figure 3 shown). In this way, when a vehicle passes through these roads (especially the turning road 12), it is not easy to skid or sideslip, ensuring the passing performance of the vehicle.
[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
