Technical Field

[0001] This utility model relates to the field of highway technology, specifically to a guardrail for highways. Background Technology

[0002] Highways, or expressways for short, are roads specifically designed for high-speed automobile travel. The regulations governing highways vary across different countries, regions, eras, and scientific and academic fields.

[0003] Because vehicles travel at high speeds on highways, guardrails are required along the sides of highways. The guardrails on both sides of highways mainly consist of posts and protective panels on top of them. Both the protective panels and posts are made of steel materials and are usually connected by steel, either by welding or by bolting the protective panels to the posts. However, existing guardrails do not have any shock-absorbing or protective devices on their surface. When a vehicle is involved in an accident, it will not be able to absorb shocks and cushion the impact, which will not only damage the vehicle but also increase the chance of injury to the driver and passengers. Utility Model Content

[0004] The purpose of this utility model is to provide a highway guardrail to solve the problem mentioned in the background art that the existing guardrails have no shock-absorbing and protective devices on their surface. When a vehicle is in danger, it will not provide shock absorption and cushioning, which will not only damage the vehicle, but also increase the probability of injury to the driver and passengers.

[0006] Preferably, the column is cylindrical, the base plate is plate-shaped, and both the movable sleeve and the fixed cylinder are cylindrical.

[0007] Preferably, the fixed cylinder is movably connected to the column via a movable sleeve, and the two ends of the buffer spring are fixedly connected to the movable sleeve and the pressure plate, respectively.

[0008] Preferably, the pressure plate is circular, and the pressure plate is slidably connected to the fixed cylinder by a buffer spring, and the connecting rod is cylindrical.

[0009] Preferably, the connecting rod is slidably connected to the pressure plate and the fixed cylinder, the protective plate is long, and both the first elastic metal plate and the second elastic metal plate have a certain curvature.

[0010] Preferably, the fixing plate is plate-shaped, the limiting block is cylindrical, and the limiting block is rotatably connected by a screw and a connecting block.

[0011] Preferably, the connecting block and the movable sleeve are fixedly connected, and the connecting block is movably connected to the column via a screw and a limiting block.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A highway guardrail includes a post 1 for erecting the guardrail. A base plate 2 is fixedly connected to the lower end of the post 1, which is used to fix the guardrail to the ground. A movable sleeve 3 is slidably connected to the surface of the post 1, which is used to move a protective plate 8, a first elastic metal plate 9, and a second elastic metal plate 10 up and down, thereby adjusting the height of the guardrail. A fixed cylinder 4 is fixedly connected to the surface of the movable sleeve 3, which is used to prevent the buffer spring 5 from shaking when compressed. A buffer spring 5 is fixedly connected to the inner surface of the fixed cylinder 4, which is used to buffer the guardrail when it is impacted, reducing the impact force. A pressure plate 6 is fixedly connected to the surface of the buffer spring 5, which is used to compress the buffer spring 5. A connecting rod 7 is fixedly connected to the surface of the pressure plate 6, which is used to connect the pressure plate 6 and the protective plate 8. The end of the connecting rod 7 away from the pressure plate 6 is fixedly connected to the protective plate 8, which is used to install the first elastic metal plate 9 and the second elastic metal plate 10. A first elastic metal plate 9 is fixedly connected to the surface of the guardrail, and a second elastic metal plate 10 is fixedly connected to the surface of the first elastic metal plate 9. The first elastic metal plate 9 and the second elastic metal plate 10 are used to buffer the guardrail when it is hit, reducing the impact force. A fixing plate 11 is fixedly connected to the upper end of the post 1. A screw 12 is threadedly connected to the surface of the fixing plate 11. The fixing plate 11 and the screw 12 are used to drive the connecting block 15 and the movable sleeve 3 to move up and down, thereby driving the guardrail 8, the first elastic metal plate 9 and the second elastic metal plate 10 to move up and down, thereby adjusting the height of the guardrail. A turntable 13 is fixedly connected to one end of the screw 12. The turntable 13 is used to rotate the screw 12. A limit block 14 is fixedly connected to the other end of the screw 12. The limit block 14 is used to limit the position of the screw 12, so that the screw 12 can drive the connecting block 15 to move up and down, while not affecting the rotation of the screw 12. A connecting block 15 is movably connected to the surface of the limit block 14. The connecting block 15 is used to drive the movable sleeve 3 to move up and down.

[0024] Furthermore, the upright 1 is cylindrical and is used to install and erect the guardrail. The base plate 2 is plate-shaped and is used to install and fix the guardrail on the ground. The movable sleeve 3 and the fixed cylinder 4 are both cylindrical. The movable sleeve 3 is used to drive the protective plate 8, the first elastic metal plate 9 and the second elastic metal plate 10 to move up and down, thereby adjusting the height of the guardrail.

[0025] Furthermore, the fixed cylinder 4 is movably connected to the column 1 via the movable sleeve 3. The fixed cylinder 4 is used to prevent the buffer spring 5 from shaking when it is compressed. The two ends of the buffer spring 5 are fixedly connected to the movable sleeve 3 and the pressure plate 6 respectively. The buffer spring 5 is used to buffer the impact when the guardrail is hit, thereby reducing the impact force generated by the impact.

[0026] Furthermore, the pressure plate 6 is in the shape of a circular plate, and the pressure plate 6 is slidably connected to the buffer spring 5 and the fixed cylinder 4. The pressure plate 6 is used to compress the buffer spring 5. The connecting rod 7 is in the shape of a cylinder, and the connecting rod 7 is used to connect the pressure plate 6 and the protective plate 8.

[0027] Furthermore, the connecting rod 7 is slidably connected to the pressure plate 6 and the fixing cylinder 4. The protective plate 8 is in the shape of a long plate. The protective plate 8 is used to install the first elastic metal plate 9 and the second elastic metal plate 10. Both the first elastic metal plate 9 and the second elastic metal plate 10 have a certain curvature. The first elastic metal plate 9 and the second elastic metal plate 10 are used to buffer the impact when the guardrail is hit, thereby reducing the impact force generated by the impact.

[0028] Furthermore, the fixing plate 11 is plate-shaped, and the fixing plate 11 and the screw 12 are used to drive the connecting block 15 and the movable sleeve 3 to move up and down, thereby driving the protective plate 8, the first elastic metal plate 9 and the second elastic metal plate 10 to move up and down, thereby adjusting the height of the guardrail. The turntable 13 is used to rotate the screw 12. The limiting block 14 is cylindrical in shape, and the limiting block 14 is rotatably connected to the connecting block 15 through the screw 12.

[0029] Furthermore, the limiting block 14 is used to limit the position of the screw 12, so that the screw 12 can drive the connecting block 15 to move up and down without affecting the rotation of the screw 12. The connecting block 15 and the movable sleeve 3 are fixedly connected. The connecting block 15 is movably connected to the column 1 through the screw 12 and the limiting block 14. The connecting block 15 is used to drive the movable sleeve 3 to move up and down.

[0030] Working principle: When a vehicle hits the guardrail, the vehicle will exert an impact force on the guardrail, which will squeeze the first elastic metal plate 9 and the second elastic metal plate 10, causing the first elastic metal plate 9 and the second elastic metal plate 10 to deform. At the same time, it will also push the pressure plate 6 to compress the buffer spring 5. After the buffer spring 5, the first elastic metal plate 9 and the second elastic metal plate 10 are deformed, they will rebound and generate a reverse force to cancel out the impact force, thereby playing a buffering role.

[0031] Rotating the turntable 13 drives the screw 12 to rotate, and the screw 12 moves up and down, thereby driving the connecting block 15 and the movable sleeve 3 connected to the connecting block 15 to move up and down, thereby adjusting the height of the protective plate 8, the first elastic metal plate 9 and the second elastic metal plate 10 connected to the movable sleeve 3, so as to make it easy to adjust and use according to the highway site conditions.
