Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a prefabricated guardrail. Background Technology

[0002] Guardrails utilize the deformation of the soil base, posts, beams, and polycarbonate sheets to absorb collision energy and force out-of-control vehicles to change direction and return to their normal driving direction, preventing vehicles from running off the road, thus protecting vehicles and passengers and reducing losses caused by accidents.

[0003] In existing road safety facilities, the installation of guardrails often requires the assembly and welding of individual parts. This process is not only cumbersome but also demands a high level of technical skill from the construction workers. The installation process requires first fixing the base, then installing the posts, beams, and other components one by one, and finally connecting them firmly together through welding or other connection methods. The installation and welding of each component is time-consuming and labor-intensive, resulting in low overall installation efficiency. Welding and other operations require specialized technical workers, which increases the difficulty of construction. If the size or position is found to be unsuitable on the construction site, adjustments are very inconvenient and can easily lead to rework, further extending the construction period. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated guardrail, comprising mounting bases and baffles, wherein mounting plates are fixedly connected inside the two mounting bases, and fixing bases are fixedly connected to opposite sides of the two mounting plates, limiting seats are sleeved on the outside of the two fixing bases, and guardrails are fixedly connected to opposite sides of the two limiting seats, guide rods are fixedly connected to the inner perimeter of the two fixing bases, sliding plates are slidably connected to the outer sides of the multiple guide rods, and pulling components are fixedly connected to the upper sides of the multiple sliding plates, the pulling components being used to drive the sliding plates to move, insert plates are fixedly connected to the opposite sides of the multiple sliding plates, the multiple insert plates are slidably connected inside the limiting bases, and return springs are sleeved on the outside of the multiple guide rods.

[0006] Furthermore, connecting plates are fixedly connected to both sides of the baffle, positioning seats are fixedly connected to the front perimeter of the guardrail, fixing boxes are fixedly connected inside the multiple positioning seats, limiting rods are fixedly connected to the inner perimeter of the multiple fixing boxes, limiting plates are slidably connected to the outside of the multiple limiting rods, buffer springs are sleeved on the outside of the multiple limiting rods, and moving blocks are fixedly connected to the opposite side of the multiple limiting plates, and the multiple moving blocks are fixedly connected to the rear of the multiple connecting plates.

[0007] Furthermore, the pulling assembly includes a pull plate and pull rods, with one end of each of the pull rods fixedly connected to the upper part of the slide plate, and the pull plates fixedly connected to the other end of each of the pull rods.

[0008] Furthermore, both ends of the plurality of return springs are fixedly connected to the opposite sides of the plurality of slide plates, and the plurality of slide plates are slidably connected inside the fixed base.

[0009] Furthermore, both sides of the interior of the two fixed seats are provided with through slots, and the multiple pull rods are slidably connected inside the through slots.

[0010] Furthermore, each of the four sides of the front of the guardrail is fixedly connected to one end of a damper, and the other ends of the multiple dampers are fixedly connected to the rear of the connecting plate.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, by pulling the pull plate, the pull rod drives the slide plate to slide along the guide rod, and the return spring is squeezed to bring the slide plate together, so that the limiting seat is placed outside the fixed seat. Then, the pull plate is released, so that the insert plate is inserted into the limiting seat to complete the fixation. This effectively simplifies the installation process and improves construction efficiency.

[0015] In this invention, when the baffle is impacted, the connecting plate squeezes the damper and the moving block, causing them to slide into the fixed box and drive the limiting plate to slide along the limiting rod, compressing the buffer spring to absorb the vibration, thereby effectively protecting the guardrail from impact and extending its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a prefabricated guardrail, comprising a mounting base 1 and a baffle 12. Mounting plates 2 are fixedly connected to the interior of each of the two mounting bases 1. Fixing bases 3 are fixedly connected to opposite sides of each of the two mounting plates 2. Limiting seats 10 are sleeved on the exterior of each of the two fixing bases 3. Guardrail plates 11 are fixedly connected to opposite sides of each of the two limiting seats 10. Guide rods 7 are fixedly connected to the interior perimeter of each of the two fixing bases 3. Sliding plates 6 are slidably connected to the exterior sides of the multiple guide rods 7. Pulling components are fixedly connected to the upper sides of the multiple sliding plates 6, and the pulling components are used to move the sliding plates 6. Multiple sliding plates 6 are fixedly connected to the opposite sides of each other with insert plates 9. Multiple insert plates 9 are slidably connected inside the limiting seat 10. Multiple guide rods 7 are fitted with return springs 8. The pulling assembly includes pull plates 4 and pull rods 5. One end of multiple pull rods 5 is fixedly connected to the upper part of the sliding plate 6. Multiple pull plates 4 are fixedly connected to the other end of multiple pull rods 5. Both ends of multiple return springs 8 are fixedly connected to the opposite sides of multiple sliding plates 6. Multiple sliding plates 6 are slidably connected inside the fixing seat 3. Through slots are opened on both sides of the interior of the two fixing seats 3. Multiple pull rods 5 are slidably connected inside the through slots.

[0025] During the installation of the guardrail panel 11, multiple pull plates 4 are first pulled. By pulling these pull plates 4, the pull rod 5 slides inside the through groove. As the pull rod 5 moves, the slide plate 6 slides synchronously outside the guide rod 7. The guide rod 7 provides a sliding path for the slide plate 6, ensuring the directionality and stability of the slide plate 6 during movement. During this process, the slide plate 6 applies pressure to the return spring 8, causing multiple slide plates 6 to move closer together within the fixed seat 3. After being compressed, the return spring 8 stores energy. When the pull plates 4 are released, the spring releases the energy. Push the slide plate 6 back to its original position. Next, put the two limiting seats 10 on the outside of the two fixed seats 3. Then, release the pull plate 4. With the help of the return spring 8, the multiple slide plates 6 quickly return to their initial positions. Driven by this action, the slide plate 6 drives the insert plate 9 to insert into the limiting seat 10. The limiting seat 10 is put on the outside of the fixed seat 3 to finally fix the position of the insert plate 9 and the slide plate 6, ensuring the stability of the guardrail 11, thereby firmly fixing the limiting seat 10. The guardrail 11 is the core part of the entire structure and is used to provide road safety protection.

[0026] Reference Figure 1 , Figure 2 and Figure 5Both sides of the baffle 12 are fixedly connected to connecting plates 19. The front of the guardrail 11 is fixedly connected to positioning seats 13. The interior of each positioning seat 13 is fixedly connected to a fixing box 14. The interior of each fixing box 14 is fixedly connected to a limit rod 15. The exterior of each limit rod 15 is slidably connected to a limit plate 17. The exterior of each limit rod 15 is fitted with a buffer spring 16. The opposite side of each limit plate 17 is fixedly connected to a moving block 18. The moving blocks 18 are fixedly connected to the rear of each connecting plate 19. One end of each damper 20 is fixedly connected to the front of the guardrail 11. The other end of each damper 20 is fixedly connected to the rear of each connecting plate 19. The baffle 12 is located at the front of the guardrail 11. The moving blocks 18 are slidably connected to the interior of the fixing box 14. One end of each buffer spring 16 is fixedly connected to the interior of each fixing box 14. The other end of each buffer spring 16 is fixedly connected to the rear of each limit plate 17.

[0027] In the event of a collision, the baffle 12 allows the connecting plate 19 to quickly apply pressure to the damper 20 and the moving block 18. The main function of the damper 20 is to mitigate the impact force and reduce the energy transfer caused by the collision, thereby protecting other parts of the system. At this time, the moving block 18, pushed by the connecting plate 19, slides smoothly into the fixed box 14 along a predetermined trajectory. This action not only mitigates the impact force but also drives multiple limiting plates 17 to slide accordingly along the outer side of the limiting rod 15. The limiting rod 15 provides a sliding path for the limiting plates 17, ensuring that the limiting plates 17 can move correctly when subjected to pressure, thereby triggering the operation of the buffer spring 16. As the limiting plates 17 move, they exert a squeezing effect on the buffer spring 16, enabling the buffer spring 16 to effectively absorb and disperse some of the energy generated during the collision. The guardrail 11 is effectively protected and avoids direct impact. The function of the buffer spring 16 is to absorb and disperse the vibration energy generated by the collision, reduce the direct impact on the guardrail 11, and protect the guardrail 11 from damage.

[0028] Working principle: When installing the guardrail panel 11, first pull multiple pull plates 4. The pull plates 4 drive the pull rod 5 to slide inside the through groove. When the pull rod 5 moves, it drives the slide plate 6 to slide outside the guide rod 7. When the slide plate 6 slides, it compresses the return spring 8, causing the multiple slide plates 6 to approach each other inside the fixed seat 3. Then, the two limit seats 10 are placed on the outside of the two fixed seats 3. Release the multiple pull plates 4. Under the action of the multiple return springs 8, the multiple slide plates 6 are driven to return to their original position, causing the slide plates 6 to drive the insert plate 9 to insert into the limit seat 10, thus fixing the limit seat 10. This completes the installation of the guardrail panel. The installation of guardrail 11 facilitates its installation, reduces on-site construction time and complexity, and improves construction efficiency. When the guardrail 12 is impacted, the connecting plate 19 presses against the damper 20 and the moving block 18. The moving block 18 slides into the fixed box 14 under pressure, and drives multiple limiting plates 17 to slide outside the limiting rod 15. This causes the limiting plates 17 to press against the buffer spring 16, which absorbs part of the vibration, effectively protecting the guardrail 11 from impact and extending its service life.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
