Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, and in particular to a passive protective netting for preventing swaying. Background Technology

[0002] In various engineering construction projects and mountain protection scenarios, anti-sway passive protective nets play a crucial role. As infrastructure construction continues to expand into areas with complex geological conditions, such as the construction of mountain roads and railways, and the advancement of mining activities, geological disasters such as landslides and rockfalls pose a serious threat to the safety of surrounding facilities and personnel. As a key facility for resisting these disasters, the performance of anti-sway passive protective nets directly affects their protective effectiveness. They need to be able to efficiently intercept falling rocks while possessing good stability, continuously functioning under various complex working conditions to ensure the safety of the area below. This has prompted continuous optimization and innovation in the structure and performance of protective nets.

[0003] Existing passive rockfall protection nets mostly employ traditional and fixed connection methods in their structural design. The netting is connected and secured to the supporting structure via welding, bolting, or other methods, and the guy ropes are typically fixed in pre-set positions. In terms of working principle, they primarily rely on the netting's own strength and toughness to block falling rocks, while the supporting structure is responsible for distributing the impact force to the foundation. When encountering a falling rock, the netting absorbs the impact through deformation, while the supporting structure strives to maintain the netting's position and prevent excessive swaying. However, this traditional design approach is gradually revealing some limitations when facing diverse real-world usage scenarios.

[0004] However, existing protective nets have significant shortcomings in the installation and adjustment of guy ropes. When the position of the guy ropes needs adjustment, or when they are damaged and require maintenance or replacement, the process is extremely cumbersome. Because the connection between the guy ropes and the protective net and supporting structure is fixed, it often requires the use of multiple tools such as wrenches and screwdrivers, and a significant amount of time and effort to disassemble multiple components to adjust or replace the guy ropes. This not only reduces work efficiency, but also makes it impossible to quickly complete guy rope maintenance in emergency situations, leading to a decline in the protective performance of the net and making it difficult to effectively cope with potential geological disaster threats, thus affecting the reliability and practicality of the entire protective system. Therefore, a passive protective net to prevent swaying is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a passive protective net to prevent swaying, which aims to improve the problem that the existing technology requires multiple tools to adjust and cannot be easily disassembled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A passive protective net for preventing swaying includes a protective net, a top post fixedly connected to the top of the protective net, a hook provided on the outer wall of the top post, a pull rope provided on the outer wall of the hook, an adjustment component provided inside the top post, and a buffer component provided at the bottom of the protective net;

[0008] The adjustment assembly includes a fixed column, one end of which is fixedly connected to one end of the hook. The top column has a slot, a rotating groove, and a sliding groove inside. The other end of the fixed column is fixedly connected to a locking column, and the outer wall of the locking column is slidably connected to the slot.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes a base, which is disposed on the outer wall of the protective net;

[0011] As a further description of the above technical solution:

[0012] The bottom of the protective net is fixedly connected to a slider, and the outer wall of the slider is slidably connected to the inside of the base.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the base is fixedly connected to a connecting column two, and the outer wall of the connecting column two is slidably connected to two sliding rings two.

[0015] As a further description of the above technical solution:

[0016] A spring is fitted on the outer wall of the second connecting column, and both ends of the spring are fixedly connected to the outer wall of the second sliding ring.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the second sliding ring is rotatably connected to a rotating rod, and the other end of the rotating rod is rotatably connected to the first sliding ring;

[0019] As a further description of the above technical solution:

[0020] A damper is fixedly connected to the outer wall of the second connecting column, and a connecting column is fixedly connected to one end of the damper.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the connecting column is fixedly connected to the outer wall of the protective net, and the inner wall of the sliding ring is slidably connected to the outer wall of the connecting column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the hook achieves its adjustment function by moving. When the hook is pulled, the hook drives the fixed column to move the locking column inside the top column, realizing the convenient placement and movement of the hook. This allows for convenient adjustment, addition, and disassembly of the pull rope, facilitating maintenance, replacement, and movement. It solves the problem that existing devices require multiple tools for adjustment and cannot be easily disassembled, thus improving the convenience of the device.

[0025] 2. In this utility model, when the protective net is subjected to pressure, it drives the connecting column to move, thereby squeezing the damper. At the same time, it drives the rotating rod to rotate and compress the spring. Then, the rebound of the spring and the damper causes the protective net to rebound, thereby buffering the protective net when it is impacted, reducing damage, solving the problem that hard contact with pressure can easily cause damage, and improving the service life of the device.

[0031] 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.

[0032] Reference Figure 1 and Figure 2The present invention provides an embodiment of a passive protective net for preventing swaying, comprising a protective net 1, which is woven from high-strength steel wire rope. This steel wire rope has good flexibility and impact resistance, and can effectively intercept falling rocks of different sizes. A top post 4 is fixedly connected to the top of the protective net 1. The top post 4 is made of high-strength alloy steel and has sufficient strength and rigidity to withstand the tension transmitted by the pull rope 2. A hook 3 is provided on the outer wall of the top post 4, and a pull rope 2 is provided on the outer wall of the hook 3. An adjustment component is provided inside the top post 4, and a buffer component is provided at the bottom of the protective net 1.

[0033] The adjustment assembly includes a fixed post 8, one end of which is fixedly connected to one end of the hook 3. A top post 4 has a slot 9, a rotating groove 6, and a sliding groove 10 inside. The size and shape of the rotating groove 6 and the sliding groove 10 are adapted to the slot 7 to ensure that the slot 7 can slide and rotate smoothly within them. The other end of the fixed post 8 is fixedly connected to the slot 7, and the outer wall of the slot 7 can slide flexibly within the slot 9, thereby adjusting the position of the hook 3. The other end of the fixed post 8 is also fixedly connected to the slot 7, and the outer wall of the slot 7 is slidably connected within the slot 9.

[0034] Specifically, in practical applications, the layout of the pull ropes 2 of the anti-sway passive protective net 1 often needs to be flexibly adjusted according to different working conditions and protection requirements. When it is necessary to adjust the position of the pull ropes 2 or add pull ropes 2, the staff can directly push the hook 3. After the hook 3 is subjected to force, it will drive the fixed column 8 connected to it to move together. As the fixed column 8 moves, the locking column 7 connected to the front end of the fixed column 8 will smoothly slide out from the original locking groove 9. At this time, the rotating groove 6 on the hook 3 can slide into another rotating groove 6 that is adapted to it. Workers can push the hook 3 to slide it to the ideal position, and then pull the hook 3 back so that the locking post 7 is locked in the corresponding slot 9, thus achieving a stable fixation and pulling of the pull rope 2. When there is a need to disassemble or assemble the pull rope 2, simply rotate the hook 3 inside the rotating slot 6 to precisely align it with the sliding slot 10, and the hook 3 and pull rope 2 can be easily pulled out through the sliding slot 10. This greatly facilitates the replacement or addition of the pull rope 2 and significantly improves the overall tensile strength and protective performance of the protective net 1.

[0035] Reference Figure 1 and Figure 3The buffer assembly includes a base 5, which is made of high-strength cast iron, a material with good compressive strength and stability. The base 5 is securely mounted on the outer wall of the protective net 1, and its interior is designed with smooth tracks to ensure smooth sliding of mating components. A slider 11 is fixedly connected to the bottom of the protective net 1, and the outer wall of the slider 11 is slidably connected to the inside of the base 5. A connecting post 15 is fixedly connected to the inner wall of the base 5. Two sliding rings 17 are slidably connected to the outer wall of the connecting post 15. The sliding rings 17 are made of aluminum alloy, which is lightweight and has good wear resistance. Their inner walls are finely machined to perfectly fit the outer wall of the connecting post 15, ensuring free sliding on the connecting post 15. A spring 18 is fitted onto the outer wall of the connecting post 15. The spring 18 is made of high-elasticity stainless steel, possessing good elasticity and fatigue resistance. Both ends of the spring 18 are firmly fixed to the outer wall of the sliding ring 17 by welding. When the sliding ring 17 slides on the connecting post 15, it can effectively compress or stretch the spring 18 to realize the storage and release of energy. Both ends of the spring 18 are fixed to the outer wall of the sliding ring 17. The outer wall of the sliding ring 17 is rotatably connected to the rotating rod 16. The other end of the rotating rod 16 is rotatably connected to the sliding ring 12. The outer wall of the connecting post 15 is fixedly connected to the damper 14. One end of the damper 14 is fixedly connected to the connecting post 13. The outer wall of the connecting post 13 is fixedly connected to the outer wall of the protective net 1. The sliding ring 12 is slidably connected to the outer wall of the connecting post 13.

[0036] Specifically, in mountainous areas and other regions prone to rockfall disasters, the anti-sway passive protective netting 1 constantly faces severe challenges. When the protective netting 1 is hit by falling rocks, the immense pressure instantly exerts a strong impact on it. At this moment, the protective netting 1 bears the brunt of the impact, and the force causes the sliding ring 12, which is closely connected to it, to begin to move. The movement of the sliding ring 12 causes the connecting column 13 to immediately compress the damper 14. Simultaneously, the sliding ring 12 slides smoothly along its predetermined track, thereby causing the rotating rod 16 to begin to rotate. During the rotation of the rotating rod 16, the sliding ring 17 slides smoothly against the outer wall of the connecting column 15, and during this process, the spring 18 is gradually compressed. Once the impact force of the falling rocks weakens, the damper 14 and the spring 18 begin to rebound using their own elastic potential energy, pushing the protective netting 1 slowly back to its initial position. In this way, the impact damage of falling rocks on the protective netting 1 is effectively reduced, greatly extending the service life of the protective netting 1 and ensuring that it can play a stable protective role for a long time.

[0037] Working principle: When it is necessary to adjust the position of the pull rope 2 or add pull rope 2, the hook 3 can be pushed. The hook 3 drives the fixed column 8 to move. Then, the fixed column 8 drives the locking column 7 to slide out from the inside of the locking groove 9, so that the rotating groove 6 slides into the inside of the rotating groove 9. Then, it is moved to slide to the appropriate position and pulled back, so that it continues to be locked in the locking groove 9 in the appropriate position for fixed pulling. When it is necessary to disassemble or assemble, it can be rotated inside the rotating groove 6 to align with the sliding groove 10, so that it can be pulled out through the sliding groove 10, which is convenient for replacing or adding pull rope 2 and increasing the pulling force.

[0038] In addition, when the protective net 1 is subjected to the pressure of falling rocks, it will impact the protective net 1. Then, the protective net 1 will drive the sliding ring 12 to move, and the connecting column 13 will squeeze the damper 14 and drive the sliding ring 12 to slide, thereby rotating the rotating rod 16. This will drive the sliding ring 17 to slide on the outer wall of the connecting column 15, compressing the spring 18. Then, the rebound of the damper 14 and the spring 18 will drive the protective net 1 back to its original position, thereby reducing the impact of falling rocks on the protective net 1 and extending its service life.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
