Description

Technical Field

[0001] This utility model belongs to the technical field of slope protection devices, and in particular relates to a replaceable combined energy dissipation device. Background Technology

[0002] my country has a complex terrain with vast mountainous areas, making it prone to frequent geological disasters such as landslides and rockfalls, posing a serious threat to transportation infrastructure such as highways and railways. To effectively prevent and control such disasters, slope protection netting systems are widely used in various slope engineering projects. These systems protect the safety of buildings and people below by intercepting falling rocks and landslides. The performance of a slope protection netting system largely depends on the performance of its core component—the energy dissipation device. This device absorbs and dissipates impact energy when the system is subjected to impact, thus achieving an energy dissipation effect.

[0003] Currently, the most commonly used energy dissipation device on the market is the pressure-reducing ring. Due to its inherent energy dissipation characteristics, the pressure-reducing ring cannot continue to play its role in energy dissipation after being intercepted and deformed. This irreversible deformation not only weakens the overall protective capability of the protective net system, but may also lead to the system facing higher risks in subsequent impacts.

[0004] To address the aforementioned issues, this application proposes a replaceable combined energy dissipation device. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable combined energy-consuming device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a replaceable combined energy-consuming device, including a sleeve with a flange end and an open end, and the sleeves are detachably connected in pairs.

[0008] The sleeve has a coaxial energy-consuming block inside, and a connecting rod is fixed to one end of the energy-consuming block and extends outward. A spring is fixedly installed between adjacent energy-consuming blocks.

[0009] The sleeve has a coaxial tapered cylinder inside, and the smaller diameter end is detachably fixed to the open end of the sleeve.

[0010] Preferably, the outer surface of the energy-consuming block has a conical structure that fits against the inner surface of the conical cylinder.

[0011] Preferably, the small-diameter end of the energy-consuming block is away from the spring, and the small-diameter end extends outward with a blocking part that abuts against the inner wall of the conical cylinder.

[0012] Preferably, the large-diameter end of the energy-consuming block is fixed with a connecting part for mounting a spring.

[0013] Preferably, one end of the connecting rod is fixed with a connector, which is detachably connected to the slope protection net.

[0014] Preferably, the outer side of the conical cylinder has an integral elastic protrusion that abuts against the inner wall of the sleeve, and the small-diameter end of the conical cylinder is blocked by a retaining ring on the inner side of the sleeve opening.

[0015] Preferably, a fixing block is fixed to the outer side of the large-diameter end of the conical cylinder.

[0016] This utility model has the following beneficial effects:

[0017] This invention increases friction by axially obstructing the sliding of the energy-consuming block, and works in conjunction with the spring to achieve double buffering protection. While effectively consuming the impact force, the adjacent energy-consuming mechanisms can work together to buffer, minimizing the impact of impacts such as rockfalls on the slope.

[0018] Furthermore, when the energy-consuming block slides outward, it pushes the small-diameter end of the conical cylinder outward to form an expansion, thereby utilizing the elastic properties of the elastic protrusion to form a third layer of protection against the impact force. At the same time, it can also apply an inward sliding squeezing force to the energy-consuming block after the operation, so that the energy-consuming block and the spring can be reset. The energy-consuming mechanism can perform impact buffering protection operations multiple times.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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.

[0029] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship 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.

[0030] Please see Figure 1-4 As shown, this utility model is a replaceable combined energy-consuming device, including a sleeve 1, which has a flange end and an open end, and the sleeves 1 are detachably connected in pairs.

[0031] The sleeve 1 has a coaxial energy dissipation block 3 inside, which is a conical plug. One end of the energy dissipation block 3 is fixed with a connecting rod 2 extending outward, and the other end is fixed with a connector 21 for detachable connection with the slope protection net or other connecting mechanism. A spring 4 is fixedly installed between adjacent energy dissipation blocks 3 to enhance the energy dissipation performance of the energy dissipation mechanism against impact.

[0032] A coaxial tapered cylinder 5 is inserted through the sleeve 1 from the flange end to the open end. The small diameter end of the tapered cylinder 5 is located at the open end of the sleeve 1, and a retaining ring 11 is integrally formed on the inner side of the open end to block the small diameter end and fix it.

[0033] Furthermore, a blocking part 31 extends outward from the small-diameter end of the energy-consuming block 3, which tightly abuts against the inner side of the conical cylinder to increase the frictional resistance when sliding outward.

[0034] Furthermore, the large-diameter end of the energy-consuming block 3 is fixed with a connecting part 32 for movably mounting the end of the spring 4. The detachable connection allows the spring 4 to be replaced separately during maintenance.

[0035] Furthermore, the outer side of the conical cylinder 5 has integral elastic protrusions 51, which are evenly distributed along the axis and abut against the inner wall of the sleeve 1. After being compressed, both the conical cylinder 5 and the elastic protrusions 51 undergo compression deformation. The small diameter end of the conical cylinder 5 is expanded, and the elastic protrusions 51 are compressed and deformed. The elastic properties are used to form a reverse reset force, which can enhance the energy dissipation effect and promote the reset of the energy dissipation block 3.

[0036] Furthermore, a fixing block 52, which is a metal block, is fixed to the outer side of the large-diameter end of the conical cylinder 5, and abuts against the inner wall of the sleeve 1.

[0037] It is understood that the energy-consuming mechanism provided by this utility model can form a three-level synergistic energy-consuming effect of frictional resistance, elastic reset and spring 4 under the action of impact force. Adjacent energy-consuming mechanisms can work together to form a buffer protection. Moreover, the installation and replacement of the energy-consuming mechanism is simple and convenient for batch maintenance and replacement operations in environments such as slopes.

[0038] A specific application of the operation process in this embodiment is as follows: When the connecting rod 2 is pulled by an impact force, it pulls the energy dissipation block 3 to slide outward. At this time, the frictional resistance between the energy dissipation block 3 and the conical cylinder 5 forms a first-level energy dissipation. Then, the small-diameter end of the connecting rod 2 is compressed and expanded, thereby squeezing the elastic protrusion 51. The reverse elastic force of the elastic protrusion 51 applies a reverse sliding thrust to the energy dissipation block 3 to form a second-level energy dissipation. At the same time, the sliding of the energy dissipation block 3 stretches the spring 4, and the spring 4 forms a third-level energy dissipation. The combined action achieves a good buffering and protection effect. Furthermore, the reverse sliding thrust applied by the elastic protrusion 51 to the energy dissipation block 3 can drive the energy dissipation block 3 to reset when the energy dissipation operation ends, and at the same time, it can also reset the spring 4, which is conducive to subsequent buffering and protection operations. Finally, when the energy dissipation mechanism needs to be replaced, it can be disassembled by the flange between the adjacent sleeves 1. At this time, the internal connecting rod 2, energy dissipation block 3, spring 4 and conical cylinder 5 can be directly taken out, and a new connecting rod 2, energy dissipation block 3, spring 4 and conical cylinder 5 can be reinstalled for reuse.
