Description

Technical Field

[0001] This utility model relates to the field of mountain protection, specifically to a clip-on type flexible protective net energy dissipator. Background Technology

[0002] Flexible protective nets, as an effective slope protection measure, are widely used in slope protection projects for preventing geological disasters such as landslides and rockfalls, as well as for mountain roads, railways, mines, and other locations. During the process of intercepting falling rocks, the energy dissipator can absorb the impact kinetic energy of the falling rocks on the protective net, ultimately slowing down the falling rocks and intercepting them within the flexible protective net.

[0003] Chinese patent CN205296181U discloses a novel perforated friction-type energy dissipator in a flexible slope protection system, such as Figure 1 The device includes a steel wire rope 6, a perforated metal plate 1, a clamp 8, and a limiting device 7. The steel wire rope 6 is connected to the perforated metal plate 1 by repeatedly winding around the holes in the perforated metal plate. One end of the steel wire rope 6 forms a loop 9 through the clamp 8, and the other end is equipped with the limiting device 7, with a length reserved at that end for free hanging. The end of the perforated metal plate 1 near the free hanging end of the steel wire rope is detachably connected to the support rope 3 of the passive flexible protection system. The loop 9 end of the steel wire rope 6 is also detachably connected to the support rope 3 of the passive flexible protection system. Although the energy dissipator disclosed in Chinese Patent CN205296181U is convenient in terms of material sourcing, manufacturing, installation, maintenance, and replacement, it only uses a single steel wire rope to absorb impact energy through friction with the holes in the metal plate. Moreover, it needs to be replaced after activation and cannot be reused. The amount of impact energy absorbed is limited by the number of holes in the metal plate, and it cannot flexibly adjust the energy dissipation level according to the actual needs of the site. The existing energy dissipator uses a single rope for force, resulting in low upper limits for friction energy dissipation and impact force withstand.

[0004] Other energy consumers on the market also have problems such as direct contact and wear when the U-shaped end of the wire rope is connected to other devices in the protection system, affecting service life and environmental adaptability, low disassembly capability, and difficulty in being applied to different mountainous terrains.

[0005] To address the aforementioned issues, this application proposes a clip-on flexible protective net energy dissipator. Utility Model Content

[0006] The technical problems to be solved by this utility model are that the energy consumption device cannot be reused, the energy consumption level cannot be flexibly adjusted according to the actual needs of the site, the single rope force, friction energy consumption and the upper limit of the impact force it can withstand are low, and the steel wire rope U-shaped end directly contacts and wears when connected to other devices of the protection system, which affects the service life, has poor environmental adaptability, low disassembly, and is difficult to apply to different mountainous terrains.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a clip-type flexible protective net energy dissipator, including: steel wire rope, steel plate, bolt, heart ring, clamp, and shackle.

[0008] Furthermore, the steel plate is composed of three layers, including a central plate and two side plates. The three layers are stacked together to form a clamping structure. One end of the clamping structure is flush, and the length of the plate at the other end is greater than that of the two plates, with a shackle mounting hole at the end. The steel wire rope is bent into a U-shape in the middle, and both ends of the steel wire rope pass through the gap formed between the plate and the two plates. The three layers have three sets of bolt mounting holes along their length. Three bolts are used to fasten the three layers together and provide pressure to the steel wire rope in the gap. The steel wire rope passes through the three bolts in sequence in the gap and through the clamping structure in a wavy direction.

[0009] Furthermore, a heart-shaped ring is installed on the inner side of the bend, and the outer side of the heart-shaped ring has an arc-shaped structure that adapts to the bending shape of the wire rope.

[0010] Furthermore, the wire rope is secured at the bend by a clamp.

[0011] Furthermore, the fixture is made of aluminum alloy.

[0012] Furthermore, the shackle mounting holes on the No. 1 plate are connected to the shackle via shackle bolts.

[0013] Furthermore, the steel plate is made of Q235 steel.

[0014] This utility model has the following beneficial effects: the energy consumer can be reused after starting, the energy consumption level can be adjusted according to actual needs, the two ends of the wire rope provide friction to provide a higher energy consumption level, the U-shaped end of the wire rope is equipped with a heart-shaped ring to extend the service life of the energy consumer, and the disassembly is high, improving the installation, maintenance, replacement and adaptability.

[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] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figure 2-4 As shown, this utility model is a clip-type flexible protective net energy dissipator, including a steel wire rope 3, a steel plate 6, a fastening bolt 4, a heart-shaped ring 1, a clamp 3, and a shackle 5.

[0026] The steel plate 6 is composed of three layers of Q235 steel, including a central plate and two side plates. The three layers are stacked together to form a steel plate structure. One end of the clamping structure is flush, and the length of the plate at the other end is greater than that of the second plate. The extended part of the plate has a shackle mounting hole 8. Each layer has three bolt mounting holes 7 longitudinally corresponding to each other in the middle. The bolt mounting holes 7 are used to install fastening bolts 4. The connection of the fastening bolts 4 includes two types: one is a fastening assembly consisting of a fastening bolt 4 and a nut; the other is a threaded connection between the fastening bolt 4 and the threaded holes of the three layers of plates. The three layers of plates are firmly fixed together and pressure is provided for the steel wire rope 2 sandwiched between the steel plates by the engagement of the pre-made internal threads in the bolt mounting holes 7 of the three layers of plates with the external threads of the bolts.

[0027] The steel wire rope 3 is bent into a U-shape in the middle, and a heart-shaped ring 1 and a clamp 3 are installed at the bend. The clamp 3 is made of aluminum alloy. The two ends of the steel wire rope 3 pass through the gaps on both sides of the steel plate 6, and pass through the gaps in sequence around the fastening bolts 4 in a wavy direction. This wavy direction increases the contact area between the steel wire rope and the steel plate, thereby increasing the friction and improving the energy dissipation effect of the entire device. When falling rocks act on the flexible protective net, the steel wire rope 3 of the energy dissipator slides in the gaps of the steel plate 6 and generates friction between the steel plate and the bolts, thereby absorbing the impact energy of the falling rocks and playing a protective role.

[0028] At the bend of the wire rope 3, after the wire rope is bent into a U-shape, the bend end is fixed with clamp 3. A heart-shaped ring 1 is installed at the bend. The arc-shaped structure of the heart-shaped ring 1 is adapted to the bending shape of the wire rope. The heart-shaped ring 1 can prevent frictional wear on the wire rope after the energy dissipator and other accessories in the flexible protective net system are connected, thus extending the service life of the wire rope.

[0029] The shackle mounting hole 8 of the middle long plate of steel plate 6 is connected to the shackle 5 through the shackle bolt 9. The connection form of the shackle bolt 9 includes two types: one is the mating structure of the shackle bolt 9 and the nut, that is, the fastening assembly composed of bolt and nut; the other is the threaded connection structure of the bolt and the threaded hole of the shackle 5, that is, the shackle 5 can be connected to other support structures through the engagement of the pre-made internal thread in the bolt hole of the shackle 5 with the external thread of the shackle bolt 9, so that the entire energy consumer can be stably installed in the protection system. The shackle 5 also makes it easy to connect or disassemble the energy consumer with other components, which is convenient for installation and maintenance.

[0030] In practical applications, when the protective net is subjected to the impact of falling rocks, the impact kinetic energy is transferred through the protective net to the steel wire rope 3 of the energy dissipator. The steel wire rope 3 generates sliding friction with the steel plate and fastening bolts 4 in the gaps on both sides of the steel plate 6. During the sliding friction process, the impact kinetic energy is consumed and converted into internal energy through friction work, thereby playing a role in buffering and energy dissipation, protecting the protective net and objects or personnel behind the protective net from injury.

[0031] This clip-on flexible protective net energy dissipator has a simple structure, low manufacturing cost, and convenient installation. It employs a dual energy dissipation method: the clip-on type not only allows the short steel plates on both sides to press the steel wire rope together by tightening bolts, increasing friction (the friction can be adjusted by loosening the bolts), but also the friction between the steel wire rope and the bolt shaft further enhances the energy dissipation effect. It has excellent energy dissipation performance and can effectively improve the safety performance of the protective net.
