Description

Technical Field

[0001] This utility model relates to a slope protection net with barbed wire coils. Background Technology

[0002] Due to geological conditions, construction excavation, or natural weathering, the slopes along highways and railways often accumulate large amounts of loose gravel. This gravel is easily loosened, slid, or even collapses under the influence of rainwater erosion, wind, or vehicle vibrations. If gravel falls from a height, it could potentially strike vehicles, railway tracks, or pedestrians below, causing serious property damage and injuries. Furthermore, the frequent activity of animals on these slopes poses a significant safety hazard as they can easily encroach on highways and railways. In the past, passive protective netting and retaining walls were commonly used for protection. However, these traditional methods still have limitations in practical application: they involve long construction periods, high construction costs, cumbersome structures, difficult replacement of parts, and high maintenance costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a slope protection net with barbed wire coils, which has a simple structure, is easy to use and process, has low cost, and has good protective effect.

[0004] To achieve the above objectives, this utility model provides a slope protection net with barbed wire coils, comprising a net body and two support rods. One end of each support rod is provided with a base, and the other end is connected to a barbed wire coil. The two support rods are connected by at least two crossbars. The support rods and crossbars are fixedly connected by locking components. Each locking component includes a surrounding portion and wings on both sides of the surrounding portion. The surrounding portion abuts against the support rod, and the wings are provided with fastening bolts for fastening to the crossbars. A connecting beam is also connected between the crossbars. Fasteners are respectively provided on the connecting beam and the support rod. The net body is connected to the support rods and the connecting beam via fasteners. The barbed wire coil is mounted on the support rod, and the crossbars are positioned between the barbed wire coil and the base.

[0005] The advantages of this design are as follows: the surrounding part of the snap-fit ​​component can quickly fit onto the support rod, and the wings are precisely connected to the crossbars via fastening bolts, eliminating the need for complex welding procedures. On-site construction requires only basic tools such as wrenches, and 1-2 people can complete the assembly of a single component. Compared with traditional welded protective nets, the construction period can be significantly shortened, making it particularly suitable for the complex construction environments of mountain roads and railways, reducing the safety risks and labor costs of steep slope operations. In terms of structural strength, the three-dimensional frame formed by at least two crossbars and connecting beams can evenly distribute the impact of falling rocks and animal collisions throughout the entire device, avoiding fractures caused by localized stress concentration. The deep-buried design of the base for fixing the support rods ensures protective stability. The net body is detachably connected via fasteners. If the net body is damaged in a localized area due to falling rocks, there is no need to dismantle the entire structure; only the fasteners need to be loosened to replace the damaged section, significantly shortening maintenance time. Furthermore, standardized components can be stocked in bulk, reducing the management difficulty of spare parts. In addition to physical barriers, the reflective properties of the barbed wire mesh can visually warn wild animals, effectively reducing the frequency of approach by animals such as deer and rabbits. This reduces traffic accidents caused by animal intrusion, protects the ecology, and eliminates the 1-2 meter blind spot caused by slope limitations in traditional protective nets. The metal components such as clamps and bolts are hot-dip galvanized, effectively reducing the overall cost. Furthermore, the prefabricated assembly eliminates the need for large-scale excavation of mountains, and the damage to surrounding vegetation during construction is controlled within 5%, meeting the environmental protection requirements for road construction in ecologically sensitive areas and achieving a synergy between protective functions and ecological protection.

[0006] As a further feature of this utility model, the fastener includes a hook body and a limiting buckle. One end of the hook body is connected to the connecting beam or support rod, and the other end is bent to form a hook. One end of the limiting buckle is connected to the connecting beam or support rod, and the other end is set close to the hook. The limiting buckle is elastically set.

[0007] The beneficial effects of this design are as follows: This design, with its hook and elastic limit buckle, significantly improves the stability and convenience of the mesh connection. During installation, simply hook the hook onto the mesh, then use the elastic deformation of the limit buckle to pry open the end. Once the hook is fully engaged, release the limit buckle, and its elastic return will secure it tightly against the hook, forming a double fixation. No additional tools are needed for tightening. Compared to traditional bolt-through connections, the assembly time for a single connection is shorter, and it avoids mesh displacement caused by loose bolts. The elastic limit buckle is made of weather-resistant elastic steel, which can maintain stable elasticity in environments ranging from -30℃ to 60℃, avoiding low-temperature brittleness or high-temperature failure, and ensuring a long-term firm connection of the net. When the net is impacted by falling rocks, the elasticity of the limit buckle can provide slight cushioning, dispersing the local force at the hook and reducing the risk of the net mesh breaking due to hard pulling. During later maintenance, there is no need to disassemble the parts; the net can be quickly removed simply by prying open the limit buckle again. Whether it is partial replacement or overall maintenance, it can further reduce the difficulty of operation and maintenance. At the same time, the elastic structure of the limit buckle does not easily accumulate mud and sand, reducing rust and jamming caused by rainwater erosion.

[0008] As a further feature of this utility model, a gap groove is provided on the hook body corresponding to the buckle position. The limiting buckle includes a connecting part and a bending part. The connecting part is connected to the connecting beam or the support rod. One end of the bending part is connected to the connecting part, and the other end is provided with an abutting tip. The abutting tip is engaged in the gap groove.

[0009] The beneficial effects of this design are as follows: The cooperation between the hook gap groove and the limiting buckle's contact tip forms a double locking structure, which greatly enhances the stability of the net connection. After the contact tip is precisely engaged in the gap groove, it not only maintains continuous contact force through the elasticity of the limiting buckle, but also prevents the hook from shifting laterally through the physical limitation of the groove. Even if the net is impacted by falling rocks, animals, or strong winds, the hook cannot slide along the hook axis or detach from the net due to the engagement of the gap groove and the tip, thus completely solving the problem that traditional elastic buckles are prone to loosening due to long-term stress.

[0010] As a further feature of this invention, a mating post is provided at the connection end between the support rod and the barbed wire cage, and the mating post is inserted into the barbed wire cage.

[0011] The advantages of this design are as follows: This configuration allows for precise insertion of the fitting post into the barbed wire coil, creating a bushing-like positioning that avoids radial misalignment common in traditional external clamp connections. This ensures the barbed wire coil and support rod remain coaxial, preventing coil tilting or displacement even under animal impact or strong winds, thus maintaining the protection range. During assembly, repeated calibration is unnecessary; initial fixation is achieved simply by inserting the fitting post. The fitting post also shares the weight and external forces of the barbed wire coil, reducing stress concentration at the support rod connection and lowering the risk of component fatigue damage. Furthermore, the fitting post's diameter can be finely adjusted to accommodate barbed wire coils of different inner diameters, improving the device's compatibility with various coil specifications.

[0012] As a further feature of this invention, the mating post is fixedly connected to the support rod by a pin, and the pin passes through the support rod, the barbed wire cage and the mating post and is then fixedly connected to the support rod by a fastening nut.

[0013] The beneficial effect of this design is that it directly restricts the sliding and circumferential rotation of the barbed wire coil along the mating column. Even if it is hit by an animal or pulled by strong winds, it can prevent the barbed wire coil from shifting or loosening, thus greatly improving the stability of the connection.

One end of each support rod 1 is provided with a base 11, and the other end is connected to a barbed wire coil 5. The two support rods 1 are connected by at least two crossbars 2. The support rods 1 and the crossbars 2 are fixedly connected by a locking member 6. The locking member 6 includes a surrounding part 61 and wings 62 provided on both sides of the surrounding part 61. The surrounding part 61 abuts against the support rod 1. The wings 62 are provided with fastening bolts for fastening to the crossbars 2. A connecting beam 3 is also connected between the crossbars 2. Fasteners 7 are provided on the connecting beam 3 and the support rod 1 respectively. The net body 4 is connected to the support rods 1 and the connecting beam 3 by the fasteners 7. The barbed wire coil 5 is provided on the support rod 1, and the crossbars 2 are provided between the barbed wire coil 5 and the base 11. The advantages of this design are as follows: the surrounding part of the snap-fit ​​component can quickly fit onto the support rod, and the wings are precisely connected to the crossbars via fastening bolts, eliminating the need for complex welding procedures. On-site construction requires only basic tools such as wrenches, and 1-2 people can complete the assembly of a single component. Compared with traditional welded protective nets, the construction period can be significantly shortened, making it particularly suitable for the complex construction environments of mountain roads and railways, reducing the safety risks and labor costs of steep slope operations. In terms of structural strength, the three-dimensional frame formed by at least two crossbars and connecting beams can evenly distribute the impact of falling rocks and animal collisions throughout the entire device, avoiding fractures caused by localized stress concentration. The deep-buried design of the base for fixing the support rods ensures protective stability. The net body is detachably connected via fasteners. If the net body is damaged in a localized area due to falling rocks, there is no need to dismantle the entire structure; only the fasteners need to be loosened to replace the damaged section, significantly shortening maintenance time. Furthermore, standardized components can be stocked in bulk, reducing the management difficulty of spare parts. In addition to physical barriers, the reflective properties of the barbed wire mesh can visually warn wild animals, effectively reducing the frequency of approach by animals such as deer and rabbits. This reduces traffic accidents caused by animal intrusion, protects the ecology, and eliminates the 1-2 meter blind spot caused by slope limitations in traditional protective nets. The metal components such as clamps and bolts are hot-dip galvanized, effectively reducing the overall cost. Furthermore, the prefabricated assembly eliminates the need for large-scale excavation of mountains, and the damage to surrounding vegetation during construction is controlled within 5%, meeting the environmental protection requirements for road construction in ecologically sensitive areas and achieving a synergy between protective functions and ecological protection.

[0016] As a further feature of this embodiment, the fastener 7 includes a hook 71 and a limiting buckle 72. One end of the hook 71 is connected to the connecting beam 3 or the support rod 1, and the other end is bent to form a hook. One end of the limiting buckle 72 is connected to the connecting beam 3 or the support rod 1, and the other end is positioned close to the hook. The limiting buckle 72 is elastically designed. The beneficial effects of this design are: the design of the hook 71 and the elastic limiting buckle 72 of the fastener 7 greatly improves the stability and convenience of the connection of the net body 4. During installation, it is only necessary to hook the hook of the hook 71 onto the mesh of the net body 4, and then use the elastic deformation of the limiting buckle 72 to pry open the end. After the hook is fully engaged, the limiting buckle 72 is released, and its elastic return will tightly adhere to the hook to form a double fixation. No additional tools are needed to tighten it. Compared with the traditional bolt through-hole connection, the assembly time for a single connection is shorter, and the displacement of the net body 4 caused by loose bolts is avoided. The elastic limit buckle 72 is made of weather-resistant elastic steel, which can maintain stable elasticity in environments ranging from -30℃ to 60℃, avoiding low-temperature brittleness or high-temperature failure, and ensuring the long-term firm connection of the net body 4. When the net body 4 is impacted by falling rocks, the elasticity of the limit buckle 72 can provide slight cushioning, dispersing the local force at the hook and reducing the risk of the net body 4 mesh breaking due to hard pulling. During later maintenance, there is no need to disassemble the parts. The net body 4 can be quickly removed by simply prying off the limit buckle 72 again. Whether it is partial replacement or overall maintenance, it can further reduce the difficulty of operation and maintenance. At the same time, the elastic structure of the limit buckle 72 does not easily accumulate mud and sand, reducing rust and jamming caused by rainwater erosion.

[0017] As a further feature of this embodiment, a gap groove is provided on the hook body 71 corresponding to the buckle position. The limiting buckle 72 includes a connecting part 721 and a bending part 722. The connecting part 721 is connected to the connecting beam 3 or the support rod 1. One end of the bending part 722 is connected to the connecting part 721, and the other end is provided with an abutting tip 723, which is engaged in the gap groove. The beneficial effect of this design is that the cooperation between the gap groove of the hook body 71 and the abutting tip 723 of the limiting buckle 72 forms a double locking structure, which greatly enhances the connection stability of the net body 4. After the abutting tip 723 is precisely engaged in the gap groove, it not only maintains a continuous abutting force by relying on the elasticity of the limiting buckle 72, but also prevents the hook body 71 from shifting laterally through the physical limitation of the groove. Even if the net body 4 is impacted by falling rocks, animals, or strong winds, the hook cannot slide along the axial direction of the hook body 71 or disengage from the mesh due to the engagement of the gap groove and the tip, thus completely solving the problem that traditional elastic buckles are prone to loosening due to long-term stress.

[0018] As a further feature of this embodiment, a mating post 12 is provided at the connection end between the support rod 1 and the barbed wire coil 5, and the mating post 12 is inserted into the barbed wire coil 5. The advantages of this configuration are: the mating post 12 is precisely inserted into the inside of the barbed wire coil 5, forming a bushing-like positioning, avoiding the radial offset that is prone to occur in traditional external clamping connections, ensuring that the barbed wire coil 5 and the support rod 1 remain coaxial. Even under animal impact or strong wind pulling, the coil cannot be tilted or shifted, ensuring that the protection range is not reduced. During assembly, there is no need for repeated position calibration; the initial fixation is completed simply by inserting the mating post 12. The mating post 12 can share the weight of the barbed wire coil 5 and external forces, reducing the stress concentration at the connection end of the support rod 1 and lowering the risk of component fatigue damage. Furthermore, the mating post 12 can be finely adjusted in diameter to adapt to barbed wire coils 5 with different inner diameters, improving the compatibility of the device with coils of different specifications.

[0019] As a further feature of this embodiment, the mating post 12 is fixedly connected to the support rod 1 by a pin. The pin passes through the support rod 1, the barbed wire coil 5, and the mating post 12, and is then fixedly connected to the support rod 1 by a fastening nut. The beneficial effect of this configuration is that it directly restricts the axial sliding and circumferential rotation of the barbed wire coil 5 along the mating post 12. Even if it encounters animal collisions or strong winds, it can prevent the barbed wire coil 5 from shifting or loosening, greatly improving the stability of the connection.

[0020] The above examples are merely one preferred embodiment of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution are all included within the protection scope of this utility model.
