Description

Technical Field

[0001] This utility model relates to the field of energy dissipation and protection technology for slope protection nets, and in particular to a novel energy dissipation device for slope protection nets. Background Technology

[0002] The new energy dissipation device for slope protection nets is based on traditional protection nets and enhances the energy absorption, energy dissipation and shock absorption capabilities of the protection system by introducing innovative technologies. Its main purpose is to improve the effectiveness of slope protection systems in dealing with large-scale landslides, collapses or rockfalls, ensure their stability and durability, and reduce possible damage. It is quite common in slope protection.

[0003] Existing technologies, such as the utility model patent with publication number CN216194807U, disclose an energy dissipation and buffer device suitable for flexible slope protection nets. This patent includes a steel barrel; a gravity damper sliding inside the steel barrel, connected to the protection net via a buffer steel wire rope; and an elastic damper set inside the steel barrel to buffer the impact force of the gravity damping. This utility model can avoid the phenomenon of flexible protection nets being damaged due to excessive local stress, improve the service life of flexible protection nets, and has low cost, compact structure, and strong practicality. When subjected to impact, it will immediately exert its buffering and energy dissipation function, and after the impact is eliminated, the device will automatically restore its original function.

[0004] During slope protection operations, it was found that slope protection nets are subject to significant impacts from rockfalls and landslides. Traditional slope protection nets use energy dissipation devices, such as pressure-reducing rings, which dissipate energy through friction between steel pipes and aluminum sleeves. However, the stamped aluminum sleeves cannot effectively ensure consistent friction between the steel pipes and aluminum sleeves in each pressure-reducing ring, leading to inconsistent friction initiation forces and unstable energy dissipation effects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the use of pressure-reducing rings as energy dissipation devices in traditional slope protection nets. These rings achieve energy dissipation through the friction between steel pipes and aluminum sleeves. However, the stamped aluminum sleeves cannot effectively ensure that the friction force between the steel pipe and the aluminum sleeve of each pressure-reducing ring is consistent, resulting in inconsistent friction starting forces and unstable energy dissipation effects.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel energy dissipation device for slope protection netting, comprising: a first steel plate, a second steel plate, and a steel wire rope. The first steel plate and the second steel plate are slidably connected on their sides that are close to each other, and U-shaped rope clips are fixedly connected to the ends of the first steel plate and the second steel plate that are far from each other. The inner walls of the two U-shaped rope clips are fixedly connected to the surface of the steel wire rope.

[0007] The effect achieved by the above components is as follows: During the protection of slopes, strong impacts are likely to occur. At this time, the protective net may not be able to completely and effectively absorb and dissipate the kinetic energy generated by the impact of the rock and soil sliding. At this time, by using the combination of the first steel plate and the second steel plate, the wire rope can be reserved with sufficient length for effective tension control, and the first steel plate and the second steel plate can achieve the effect of energy dissipation through friction. The structure is simple and the performance is stable.

[0008] Preferably, both the first steel plate and the second steel plate have grooves on their surfaces, and the grooves have a vertical cross-section.

[0009] The effect achieved by the above components is to adjust and limit the position of the bolts by means of the grooves opened in the first steel plate and the second steel plate.

[0010] Preferably, a plurality of bolts slide through the inner walls of the two grooves, and the plurality of bolts are evenly distributed on the inner walls of the grooves.

[0011] The effect achieved by the above components is as follows: by using the limit between the bolt and the first and second steel plates, it helps to control the torque of the bolt to achieve the same pressure on the steel plates, thereby determining the value of the friction force, making the starting force of the energy dissipation device consistent, and achieving the purpose of protecting the system.

[0012] Preferably, an upper washer is fitted on the upper arc surface of the bolt, and a lower washer is fitted on the lower arc surface of the bolt. The upper washer abuts against the upper surface of the first steel plate, and the lower washer abuts against the lower surface of the second steel plate.

[0013] The effect achieved by the above-mentioned components is that when the bolts are connected and fixed between the first steel plate and the second steel plate, the upper and lower washers at both ends of the bolts can be used for protection to prevent the bolts from loosening and falling off.

[0014] Preferably, the U-shaped rope clip is a stainless steel rope clip, the U-shaped rope clip is symmetrically curved in a U-shape, and the inner arc surface of the U-shaped rope clip is provided with anti-slip texture.

[0015] The effect achieved by the above components is that the U-shaped bending rope clip made of stainless steel can quickly fix and protect the position of the wire rope, preventing the wire rope from loosening and falling off.

[0016] Preferably, the bolt is a carbon steel bolt, and the length of the bolt is adapted to the thickness of the first steel plate and the second steel plate.

[0017] The effect achieved by the above components is that the carbon steel bolts can be fixed and limited for a long time, and have good strength and toughness.

[0018] Compared with related technologies, the novel energy dissipation device for slope protection netting provided by this utility model has the following beneficial effects:

[0019] This utility model provides a novel energy dissipation device for slope protection nets, featuring dynamic energy dissipation and structural stability: the sliding connection design between the first and second steel plates allows the device to absorb energy through controllable frictional displacement during impact, preventing instantaneous overload failure of the rigid structure; the adjustable cooperation between the groove and the bolts allows for preset friction thresholds, ensuring consistent energy dissipation starting force and adapting to different impact intensity scenarios. Maintainability and adaptability: by adjusting the position of the bolts in the groove, the initial distance between the two steel plates can be flexibly changed to accommodate different tension requirements of the protection net; the combination of carbon steel bolts and stainless steel U-shaped rope clips balances strength and corrosion resistance, extending the device's service life. Anti-loosening and safety: the elastic buffering effect of the upper and lower gaskets reduces the risk of bolt loosening due to vibration; the anti-slip texture on the inner wall of the U-shaped rope clip and the double-ear bolt locking structure provide double protection for the reliability of the wire rope fixation.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 4The present invention provides a novel energy dissipation device for slope protection netting, comprising: a first steel plate 1, a second steel plate 2 and a steel wire rope 7. The first steel plate 1 and the second steel plate 2 are slidably connected on the side close to each other, and U-shaped rope clips 3 are fixedly connected to the ends of the first steel plate 1 and the second steel plate 2 that are far from each other. The inner walls of the two U-shaped rope clips 3 are fixedly connected to the surface of the steel wire rope 7.

[0028] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 4 Both the first steel plate 1 and the second steel plate 2 have grooves 8 on their surfaces. The grooves 8 have vertical cross-sections. Several bolts 4 slide through the inner walls of the two grooves 8. The bolts 4 are evenly distributed on the inner walls of the grooves 8. An upper washer 5 is fitted on the upper arc surface of the bolt 4, and a lower washer 6 is fitted on the lower arc surface of the bolt 4. The upper washer 5 abuts against the upper surface of the first steel plate 1, and the lower washer 6 abuts against the lower surface of the second steel plate 2. The U-shaped rope clip 3 is a stainless steel rope clip. The U-shaped rope clip 3 is symmetrically curved in a U-shape, and the inner arc surface of the U-shaped rope clip 3 is provided with anti-slip texture. The bolts 4 are carbon steel bolts, and the length of the bolts 4 is adapted to the thickness of the first steel plate 1 and the second steel plate 2.

[0029] The working principle of the novel energy dissipation device for slope protection netting provided by this utility model is as follows: During the operation of the slope protection netting, the energy dissipation device will be used to effectively dissipate energy. First, the first steel plate 1 and the second steel plate 2 are connected, and multiple bolts 4 are connected to the sliding grooves 8 opened on the surfaces of the first steel plate 1 and the second steel plate 2. Anti-slip operation is achieved using upper washers 5 and lower washers 6 at both ends of the bolts 4. Next, two U-shaped rope clips 3 are fixed to the ends of the first steel plate 1 and the second steel plate 2 that are far apart from each other. Finally, the steel wire rope 7 is fixed and connected to the U-shaped rope clips 3, with a certain length reserved for it. During operation, the flexible slope protection system uses "softness to overcome hardness," using its own plastic deformation to offset the impact kinetic energy of falling rocks. The force of the entire system is transmitted to the underground anchor rods through the steel wire rope 7. To prevent the steel wire rope 7 from breaking during the stress process, a certain buffer distance and energy consumption are required for the steel wire rope 7. When the tension of the wire rope 7 is greater than the starting force of the energy dissipation device, the steel plate begins to dissipate energy through sliding friction. When the energy dissipation device is activated to its limit position, the wire rope 7 intervenes and is subjected to force together with the energy dissipation device. The main components of the energy dissipation device are the first steel plate 1, the second steel plate 2, the bolts 4, and the U-shaped rope clamps 3. The width, thickness, and length of the first steel plate 1 and the second steel plate 2, as well as the number and size of the bolts 4, are adjusted according to different design energy levels. When the length of a single steel plate is less than 1m, two bolts 4 are used; when it is greater than or equal to 1m, three bolts 4 are used. At the same time, the size of the bolts 4 is also adjusted according to the design energy level.
