Description

Technical Field

[0001] This utility model belongs to the field of highway anti-collision technology, specifically relating to a highway anti-collision pier. Background Technology

[0002] Highway crash barriers are facilities used to prevent vehicle collisions, mainly installed at the ends of road guardrails and in central medians. They are typically 30-50 centimeters high and are usually made of high-strength materials such as reinforced concrete or steel plates.

[0003] Most crash barriers are currently manufactured as a single unit, with holes on both sides for inserting guardrails between them. They offer poor cushioning during vehicle collisions, typically relying on rigid restraint to stop the vehicle. Therefore, the impact and damage from crash barriers to vehicles during a collision are relatively high. Even if some crash barriers have added buffer structures, these only act on the main body of the crash barrier and cannot provide cushioning when a vehicle hits the guardrails. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a highway crash barrier that solves the problem that current crash barriers are generally manufactured as a single unit, with insertion holes on both sides for connecting guardrails between them. This results in poor buffering during vehicle collisions, typically relying on rigid restraint to stop the vehicle. Therefore, the impact and damage to the vehicle from the crash barrier during a collision are relatively high. Even if some crash barriers have added buffer structures, these only act on the main body of the crash barrier and fail to provide buffering when the vehicle hits the guardrail.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highway crash barrier, comprising side blocks arranged side by side, a buffer body between the side blocks, buffer grooves symmetrically formed on the side of the buffer body near the side blocks, buffer rods arranged on the inner side of the buffer grooves, the upper end of the buffer grooves being rotatably connected to both the side blocks and the buffer body, springs fixedly arranged side by side between the lower side of the buffer rods and the inner wall of the buffer grooves, a seat plate arranged on the lower side of the buffer rods, and insertion holes arranged side by side on the upper side of the side blocks on the opposite sides, the insertion holes penetrating into the inner side of the buffer body.

[0006] The beneficial effects of this utility model are as follows: When the guardrail or buffer is hit by a vehicle, the upper end of the buffer rod is rotatably connected to the side block and the buffer. The side block and the buffer will rotate relative to the buffer rod under the force, and at the same time, the spring will be compressed. The spring provides buffering for the side block and the buffer, avoiding stopping the vehicle directly through rigid collision, thereby reducing the reverse impact force and the degree of damage to the vehicle during the collision. Moreover, when the guardrail is hit, it can also play a buffering role like the buffer when it is hit, increasing the protective effect of this device during use.

[0007] To facilitate the disassembly and assembly of the buffer bar;

[0008] As a further improvement to the above technical solution: each of the side blocks that are far apart from each other is threaded with a plurality of bolts, and each bolt passes through the side block and is threadedly connected to the buffer body.

[0009] The beneficial effects of this improvement are: the use of bolts to fix the side blocks and the buffer body facilitates the disassembly and assembly of the buffer rod.

[0010] To enhance the cushioning and protective effect of the buffer;

[0011] As a further improvement to the above technical solution: the upper side of the buffer body is open, the inner side of the buffer body is filled with sand, and a cover plate is provided at the opening of the buffer body.

[0012] The beneficial effects of this improvement are: the buffer body is not made solid, but filled with sand. While providing counterweight for the device, when the buffer body is impacted, the impact surface of the buffer body is concave, and the internal sand particles are squeezed and flow, which can also provide a better buffering effect for the vehicle.

[0013] To increase friction during a side impact with a vehicle;

[0014] As a further improvement to the above technical solution: both sides of the buffer body are provided with convex strips at equal intervals.

[0015] The beneficial effects of this improvement are: in a side impact, the vehicle will slide relatively far on its sides due to the impact force, and the area of ​​damage will also increase. By setting the convex strip, the friction with the vehicle during a side impact is increased, which can better stop the vehicle and thus reduce the area of ​​damage to the vehicle.

[0016] In order to adjust the protective height of this device to a certain extent;

[0017] As a further improvement to the above technical solution: each of the buffer rods is provided with a connecting rod inserted into its lower side, the lower end of the connecting rod is fixedly connected to the seat plate, and each of the buffer rods is provided with a bolt 2 threaded on its lower side away from the buffer body, the bolt 2 penetrating the buffer rod and contacting the connecting rod.

[0018] The beneficial effect of this improvement is that by inserting the plug rod into the buffer rod and tightening it with bolt two, the protective height of this device can be adjusted to a certain extent.

[0019] To increase the stability of this device when placed on the ground;

[0020] As a further improvement to the above technical solution: a fixing block is provided at each of the four corners on both sides of the base plate, and a mounting hole is provided through the upper side of the fixing block.

[0021] The beneficial effect of this improvement is that the base plate is fixed to the ground by driving anchor bolts into the mounting holes of the fixing block, which increases the stability of the device when placed on the ground.

[0022] For use as a reflective warning at night;

[0023] As a further improvement to the above technical solution: each of the side blocks is equipped with a reflector at its upper end.

[0024] The beneficial effect of this improvement is that it can be used for nighttime reflective warnings.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] like Figure 1 — Figure 4As shown: A highway crash barrier includes side blocks 1 arranged side by side, with a buffer body 2 between the side blocks 1. Each buffer body 2 has symmetrically formed buffer grooves 3 on the side closest to the side blocks 1. A buffer rod 4 is provided inside each buffer groove 3. The upper end of each buffer groove 3 is rotatably connected to both the side blocks 1 and the buffer body 2. Springs 6 are fixedly arranged side-by-side between the lower side of each buffer rod 4 and the inner wall of the buffer groove 3. A seat plate 5 is provided on the lower side of each buffer rod 4. Insertion holes 8 are formed side-by-side on the upper side of each of the side blocks 1 on the side furthest from each other. The insertion holes 8 penetrate into the inner side of the buffer body 2. When the barrier or buffer body 2 is hit by a vehicle, the upper end of the buffer rod 4 is rotatably connected to both the side blocks 1 and the buffer body 2. Side block 1 and buffer body 2 rotate relative to buffer rod 4 under the action of force, which compresses spring 6. Spring 6 provides cushioning for side block 1 and buffer body 2, preventing the vehicle from stopping directly through rigid collision, thereby reducing the reverse impact force and damage to the vehicle during collision. The guardrail also provides cushioning when impacted, similar to buffer body 2, increasing the protective effect of the device during use. Multiple bolts 7 are threaded onto the opposite sides of each side block 1, and these bolts 7 thread through side block 1 and connect to buffer body 2. The bolts 7 are used to fix the side block 1 and buffer body 2, facilitating the disassembly and assembly of buffer rod 4. The upper side of buffer body 2 is open. The inner side of the buffer body 2 is filled with sand. A cover plate 9 is fitted over the opening of the buffer body 2. The buffer body 2 is not solid; by filling it with sand, it serves as a counterweight for the device. When the buffer body 2 is impacted, the impact surface of the buffer body 2 is concave, and the internal sand is compressed and flows, providing excellent cushioning for the vehicle. Both sides of the buffer body 2 are equally spaced with raised strips 10. During a lateral impact, the vehicle will slide further and the damage area will increase. The raised strips 10 increase the friction during a lateral impact, better stopping the vehicle and reducing the damage area. Insertion rods 11 are inserted into the lower side of each buffer rod 4. The lower end of the plug rod 11 is fixedly connected to the base plate 5. The lower side of the buffer rod 4 away from the buffer body 2 is threaded with bolts 12. The bolts 12 penetrate the buffer rod 4 and contact the plug rod 11. The plug rod 11 is plugged into the buffer rod 4 and tightened with bolts 12 to adjust the protective height of the device to a certain extent. The four corners of both sides of the base plate 5 are provided with fixing blocks 13. The upper side of the fixing blocks 13 is provided with mounting holes. The base plate 5 is fixed to the ground by driving anchor bolts through the mounting holes of the fixing blocks 13 to increase the stability of the device on the ground. The upper end of the side blocks 1 is provided with reflective lights 14 for nighttime reflective warning.

[0033] Working principle and usage process of this utility model:

[0034] In use, this device is placed on the road. The devices are assembled by inserting railings through the insertion holes 8 between the side blocks 1. When the railing or buffer 2 is impacted by a vehicle, the upper end of the buffer rod 4 is rotatably connected to the side blocks 1 and buffer 2. The side blocks 1 and buffer 2 will rotate relative to the buffer rod 4 under the force, simultaneously compressing the spring 6. The spring 6 provides cushioning for the side blocks 1 and buffer 2, preventing the vehicle from stopping directly through a rigid collision, thereby reducing the reverse impact force and the degree of damage during a vehicle collision. Furthermore, the railing also provides a cushioning effect when impacted, similar to the buffer 2. To enhance the protective effect of the device during use, multiple bolts 7 are threaded onto the opposite sides of the side blocks 1. These bolts 7 penetrate the side blocks 1 and are threadedly connected to the buffer body 2. The bolts 7 are used to securely connect the side blocks 1 and the buffer body 2, facilitating the disassembly and assembly of the buffer rod 4. Furthermore, the upper side of the buffer body 2 is open, and the inside of the buffer body 2 is filled with sand. A cover plate 9 is fitted over the opening of the buffer body 2. The buffer body 2 is not solid; by filling it with sand, it serves as a counterweight for the device. When the buffer body 2 is impacted, the buffer body 2... The impact surface is concave, and the internal sand particles are compressed and flowed, which can also provide a good cushioning effect for the vehicle. In addition, during use, both sides of the buffer body 2 are equally spaced with raised strips 10. In the event of a side impact, the vehicle will slide relatively far on the sides due to the impact force, and the damage area will also increase. By setting the raised strips 10, the friction with the vehicle during a side impact can be increased, which can better stop the vehicle and reduce the damage area. In addition, the lower side of the buffer rod 4 is inserted with a connecting rod 11, and the lower end of the connecting rod 11 is fixedly connected to the seat plate 5. The lower side of the buffer rod 4 away from the buffer body 2 is threaded with a thread. Bolt 12 penetrates the buffer rod 4 and contacts the plug rod 11. The plug rod 11 is inserted into the buffer rod 4 and tightened by bolt 12. This is used to adjust the protective height of the device to a certain extent. In addition, during use, fixing blocks 13 are provided at the four corners of both sides of the base plate 5. The upper side of the fixing block 13 has a through hole. The base plate 5 is fixed to the ground by driving anchor bolts through the mounting holes of the fixing blocks 13 to increase the stability of the device on the ground. In addition, during use, reflectors 14 are provided at the upper end of the side blocks 1 for nighttime reflective warning.
