[0002] Guardrails are a type of safety facility used to protect people or objects from harm. The history of guardrails can be traced back to ancient times, when people used materials such as wooden fences and stone walls to protect their homes or territories. With the development of society and the advancement of science and technology, the materials and designs of guardrails are also constantly improving. Today, guardrails have developed into safety facilities with multiple functions that can adapt to the needs of different scenarios. In civil engineering projects, in order to ensure the safety of workers and prevent dangerous accidents, the laws and regulations of many countries and regions stipulate that guardrails must be installed on construction sites.

[0003] Existing guardrails, especially in the field of architecture and construction, are generally designed as large and regular-shaped units. This design causes great inconvenience during transportation because they require more space and are difficult to load effectively on standard-sized transport vehicles.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a detachable guardrail based on civil engineering, including a base 1 and a railing 5, a driving assembly is fixed inside the base 1, and two sliders 20 are threadedly connected to the middle of the driving assembly, and the tops of the two sliders 20 are rotatably connected to the support rods 6, and the middle parts of the two support rods 6 are rotatably connected to the rotating shaft 22. The driving assembly will drive the two sliders 20 to slide toward each other, thereby driving the two support rods 6 to rotate, and the rotating shaft 22 is fixedly connected to the middle of the railing 5, and the tops of the two support rods 6 are rotatably connected to the slider 24, and the tops of the two sliders 24 are slidably connected to the railing 28, thereby making the railing 5 and the railing 28 rise and fall, thereby realizing the lifting function of the guardrail, and the guardrail can be folded when it needs to be transported, and the guardrail can be raised when it needs to be used, which greatly improves the work efficiency.

[0032] Reference Figure 1-Figure 3 One end of the railing 5 is fixedly connected to a limit plate 18, and the other end of the railing 5 is provided with an installation opening 14. A spring 11 is fixedly connected inside the railing 5, and one end of the spring 11 is fixedly connected to a limit block 12. The limit plate 18 of one guardrail is aligned with the installation opening 14 of another guardrail and inserted. The limit plate 18 will squeeze the limit block 12, so that the limit block 12 slides inward to squeeze the spring 11 until the limit plate 18 enters the bottom of the installation opening 14, and the limit block 12 that loses pressure returns to its original position, thereby completing the installation of the guardrail. There are two top rods slidably connected to the middle part of the railing 5. 15, one end of the two push rods 15 is fixedly connected with a handle 16, and the middle parts of the two push rods 15 are fixedly connected to a limiting block 17, and the other ends of the two push rods 15 are in contact with the limiting block 12. The handle 16 is pressed inward by hand, and the two push rods 15 will squeeze the limiting block 12, and the limiting block 12 will slide inward again to squeeze the spring 11. The width of the limiting plate 18 can just pass through between the two push rods 15. At this time, the limiting plate 18 can be pulled out to complete the disassembly, thereby realizing the installation and disassembly functions of the guardrail, facilitating the early installation and later disassembly of the guardrail, and greatly saving working time.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The driving assembly includes a motor 19, which is fixedly connected to the inside of the base 1. The output end of the motor 19 is fixedly connected to a bidirectional threaded rod 21. Two sliders 20 are threadedly connected to the middle of the bidirectional threaded rod 21. The motor 19 is started to drive the bidirectional threaded rod 21 to rotate. The two sliders 20 will slide toward each other on the bidirectional threaded rod 21. A counterweight block 2 is fixedly connected to the bottom of the base 1. The counterweight block 2 is used to add counterweight to the bottom of the guardrail to make the entire guardrail more stable. The two ends of the base 1 are fixedly connected to the waterproof board 10. The two corners of the two waterproof boards 10 are fixedly connected to the anti-collision angle 9. The anti-collision angle 9 can effectively prevent the occurrence of collisions during transportation. To prevent damage caused by bumps, the front and rear sides of the railing 5 are fixedly connected with rainproof plates 4. The waterproof plate 10 and the rainproof plate 4 effectively prevent the erosion of rain on the device and extend the service life of the device. The top of the base 1 is fixedly connected with a baffle 3, and the middle part of the limit block 12 is fixedly connected with a slide bar 13. The slide bar 13 is slidably connected to the inside of the railing 5. The top of the railing 5 is fixedly connected with two limit columns 23. The limit columns 23 are used to limit the position of the railing 2 8 to prevent it from sliding. The two limit columns 23 are both slidably connected to the middle part of the railing 2 8. The top of the railing 2 8 is fixedly connected with two warning lights 7. The warning lights are used to alert workers to danger.

[0034] Working principle: start the motor 19 to drive the bidirectional threaded rod 21 to rotate, and the two sliders 20 will slide toward each other on the bidirectional threaded rod 21, thereby driving the two support rods 6 to rotate, and then the railing 1 5 and the railing 2 8 rise and fall, thereby realizing the lifting function of the guardrail. The guardrail can be folded when it needs to be transported, and raised when it needs to be used, which greatly improves work efficiency.

[0035] The limiting plate 18 of one guardrail is aligned with the installation opening 14 of the other guardrail and inserted. The limiting plate 18 will squeeze the limiting block 12, so that the limiting block 12 slides inward to squeeze the spring 11 until the limiting plate 18 enters the bottom of the installation opening 14 and the limiting block 12 that loses pressure returns to its original position, thereby completing the installation of the guardrail. When it needs to be disassembled, the handle 16 is pressed inward by hand, and the two push rods 15 will squeeze the limiting block 12, and the limiting block 12 slides inward to squeeze the spring 11 again. The width of the limiting plate 18 can just pass through between the two push rods 15. At this time, the limiting plate 18 can be pulled out to complete the disassembly, thereby realizing the installation and disassembly functions of the guardrail, facilitating the early installation and later disassembly of the guardrail, and greatly saving working time.
