Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a retractable energy-dissipating protective net supporting steel column structure. Background Technology

[0002] In slope protection netting systems, steel columns are crucial supports for the netting. When rocks or debris fall from the slope onto the netting, both the netting and the steel columns experience significant impact. Existing slope protection netting systems typically use energy-dissipating rings to absorb this impact. However, relying solely on energy-dissipating rings is ineffective. When large rocks or debris fall, the rings cannot provide sufficient cushioning, potentially damaging the slope protection netting system. Utility Model Content

[0003] To address the aforementioned issues, this application provides a telescopic energy-dissipating protective net support steel column structure, which can effectively buffer and dissipate energy, reducing the probability of damage to the slope protection net system.

[0004] The objective of this utility model is achieved through the following technical solution: a retractable energy-dissipating protective net supporting steel column structure, comprising:

[0005] A base and a swingable steel column assembly connected to the base; the steel column assembly includes a swinging steel column and a buffer steel column coaxially connected to the swinging steel column via a buffer mechanism; when the buffer steel column is subjected to axial pressure, the buffer mechanism contracts to cause the steel column assembly to contract.

[0006] The buffer mechanism includes a mounting cavity disposed on the swing steel column, a spring disposed in the mounting cavity, and a transmission arm with one end connected to the buffer steel column and the other end extending into the mounting cavity and connected to a push plate; when the buffer steel column is subjected to axial pressure, the transmission arm moves along the mounting cavity to cause the steel column assembly to contract.

[0007] The number of buffer mechanisms is two, and the two buffer mechanisms are located on both sides of the buffer steel column and the swing steel column, respectively.

[0008] Both the buffer steel column and the swing steel column are H-beams; an upper end plate and a lower end plate are spaced apart between the upper flange plate and the lower flange plate of the swing steel column, and a sealing plate is connected between the upper end plate and the lower end plate. The upper end plate, the lower end plate, the sealing plate and the web plate of the swing steel column together form the mounting cavity, and the transmission arm extends into the mounting cavity after passing through the upper end plate.

[0009] Two stiffening plates are spaced apart on the base. A rotating plate is provided at the end of the swing steel column away from the buffer steel column. The rotating plate is rotatably installed between the two stiffening plates via a rotating pin.

[0010] Compared with the prior art, this application has the following beneficial effects:

[0011] (1) The buffer mechanism of this utility model can drive the buffer steel column to contract, so that the steel column assembly has a buffer energy dissipation function, which can absorb the impact force of falling rocks and objects and protect the slope protection net system.

[0012] (2) The steel column assembly of this utility model can swing up and down relative to the base. By swinging up and down, it can also absorb part of the impact force of falling rocks and objects, thereby improving the buffer performance of the slope protection net system.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0020] Example

[0021] like Figure 1As shown, this embodiment discloses a telescopic energy-dissipating protective net support steel column structure, including a base 1 and a swingable steel column assembly connected to the base 1. The steel column assembly includes a swinging steel column 4, a buffer mechanism, and a buffer steel column 7. The buffer steel column 7 is coaxially connected to the swinging steel column 4 via the buffer mechanism. The buffer mechanism is telescopic; therefore, when the buffer steel column 7 is subjected to axial pressure, the buffer mechanism contracts, thereby causing the steel column assembly to contract and achieve a buffering function.

[0022] Specifically, such as Figure 2 As shown, the buffer mechanism includes a mounting cavity on the swing steel column 4, a spring 12 disposed in the mounting cavity, and a transmission arm 6 with one end connected to the buffer steel column 7 and the other end extending into the mounting cavity and connected to a push plate 11.

[0023] In this embodiment, both the buffer steel column 7 and the swing steel column 4 are H-beams. An upper end plate 10 and a lower end plate 13 are spaced apart between the upper and lower flange plates of the swing steel column 4. A sealing plate 5 is detachably connected between the upper end plate 10 and the lower end plate 13 by bolts. Thus, the upper end plate 10, the lower end plate 13, the sealing plate 5, and the web of the swing steel column 4 together form the aforementioned mounting cavity. The transmission arm 6 is a square tube, one end of which is fixed to the buffer steel column 7 by bolts, and the other end passes through a hole in the upper end plate 10 and extends into the mounting cavity, where it is welded or threaded to the push plate 11.

[0024] During installation, first install the spring 12 and push plate 11 into the mounting cavity, then insert the transmission arm 6 into the mounting cavity, and connect the transmission arm 6 to the push plate 11. Finally, install the sealing plate 5. The push plate 11 abuts against the spring 12. When the buffer steel column 7 is subjected to axial pressure, the transmission arm 6 and push plate 11 move along the mounting cavity, thereby causing the steel column assembly to contract and achieve the buffering function. When the impact force disappears, under the pushing force of the spring 12, the transmission arm 6 pushes the buffer steel column 7 to reset.

[0025] In a specific configuration, the number of buffer mechanisms can be set to two, with the two buffer mechanisms located on either side of the buffer steel column 7 and the swing steel column 4, respectively, to further improve their buffering performance. Figure 3 As shown.

[0026] like Figure 1 As shown, two stiffening plates 2 are spaced apart on the base 1. A rotating plate 3 is provided at the end of the swinging steel column 4 away from the buffer steel column 7. The rotating plate 3 is rotatably installed between the two stiffening plates 2 via a rotating pin 14. In this way, the entire steel column assembly can swing with the rotating pin 14 as the fulcrum.

[0027] In use, the base 1 is cast onto the slope, and the entire steel column assembly is pulled by a traction steel wire rope, allowing it to be installed at a certain angle on the slope. The protective net is installed on top of the steel column assembly supporting the multiple telescopic energy dissipation protective net structures. When rocks fall from the slope onto the protective net, the impact force is applied to the telescopic energy dissipation protective net supporting steel column structure through the protective net. The steel column assembly is compressed, and the buffer steel column 7 on it contracts towards the swinging steel column 4 to buffer the impact force. At the same time, when the telescopic energy dissipation protective net supporting steel column structure is impacted, the steel column assembly swings at a certain angle relative to the base 1, which can also buffer part of the impact force and prevent the impact force of falling rocks from damaging the protective net system.

[0028] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0029] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
