Description

Technical Field

[0001] This utility model relates to the field of geological disaster management technology, specifically to a landslide and rockfall buffer and protection device. Background Technology

[0002] Rockfalls and rockfalls are geological phenomena in which rocks and soil, influenced by various factors, suddenly detach from a slope under the influence of gravity, move downwards, and eventually accumulate in relatively flat areas or near obstacles. The powerful impact of falling and rolling rocks can cause serious injury, especially in mountainous areas where rockfalls are often characterized by their frequent occurrence, suddenness, and randomness, making them difficult to predict and posing significant hazards to transportation routes, buildings, and personal safety. Methods for preventing rockfall disasters can be divided into two main categories: active protection and passive protection. Active protection aims to prevent potential rockfall instability, such as removing unstable rock masses, anchoring, and shotcreting. Passive protection, on the other hand, allows rockfalls to occur but prevents them from causing harm, such as retaining walls and rockfall barriers.

[0003] After long-term use, fence-type protective structures will deform due to collisions with gravel and rocks. Existing fence-type protective structures are fixed together with bolts. When replacing them, workers need to tighten multiple bolts, which is not only time-consuming and labor-intensive, but also inefficient in terms of installation and replacement, making them inconvenient to use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a landslide and rockfall buffer protection device, comprising a guardrail, a pair of vertically aligned connecting plates fixed to one side of the guardrail, the two connecting plates being located on the upper and lower sides of the guardrail respectively, and connecting holes being provided on the connecting plates; multiple fixing plates fixed to the other side of the guardrail, and a bidirectional long screw rod rotatably mounted on the fixing plate; and a snap-fit ​​assembly mounted on the bidirectional long screw rod for connecting and fixing multiple guardrails together.

[0005] Furthermore, the snap-fit ​​assembly includes a screw connector threaded onto the bidirectional long screw, a plug portion fixed on the screw connector, and an internal thread adapted to the bidirectional long screw at the center of the screw connector and the plug portion. The plug portion is adapted to the connecting hole, and the two screw connectors located on the same bidirectional long screw can be close to or far from each other.

[0006] Furthermore, a pair of extension plates are provided on one side of the guardrail, with each pair of adjacent extension plates forming a group, and a connection notch is provided between them, the connection notch being adapted to the connecting plate.

[0007] Furthermore, a through hole is provided on the extension plate, which is adapted to the plug-in portion.

[0008] Furthermore, a hexagonal fixing sleeve is sleeved and fixed in the middle of the bidirectional long screw.

[0009] Furthermore, a fixed base plate is fixed to the bottom of the guardrail, and multiple evenly distributed support rods are rotatably installed on one side of the guardrail.

[0010] Furthermore, a positioning groove is provided on the guardrail, and a positioning slide rod adapted to the positioning groove is fixed on the screw connector. The positioning slide rod can slide within the positioning groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting up a fixing plate, a two-way long screw rod, a hexagonal fixing sleeve, a screw connector, a connecting plate, a connecting hole, a plug-in part, a through hole, and a connecting notch, when connecting multiple guardrails, simply install the connecting plate on two guardrails into the connecting notch, and then rotate the two-way long screw rod clockwise to force the screw connectors on the same side to move away from each other until the plug-in part is inserted into the connecting hole and the through hole. Disassembly is also simple; just rotate counterclockwise to release the fixation. The operation is simple, facilitates efficient replacement or installation of guardrails, saves manpower, and is highly practical. Attached Figure Description

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] like Figures 1-5 This embodiment provides a landslide and rockfall buffer protection device, including a guardrail 1, a fixed base plate 2 fixed at the bottom of the guardrail 1, multiple evenly distributed support rods 3 rotatably installed on one side of the guardrail 1, a pair of vertically aligned connecting plates 8 fixed on one side of the guardrail 1, the two connecting plates 8 being located on the upper and lower sides of the guardrail 1 respectively, and connecting holes 9 being opened on the connecting plates 8; multiple fixing plates 4 fixed on the other side of the guardrail 1, and a bidirectional long screw rod 5 rotatably installed on the fixing plate 4; it also includes a snap-fit ​​assembly, which is installed on the bidirectional long screw rod 5 to connect and fix multiple guardrails 1 together, and a hexagonal fixing sleeve 6 is sleeved and fixed in the middle of the bidirectional long screw rod 5. The hexagonal fixing sleeve 6 is similar to a nut, and the operator can engage and tighten it with an adjustable wrench during operation.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the snap-fit ​​assembly includes a screw connector 7 threaded onto a bidirectional long screw 5, and a plug part 10 fixed on the screw connector 7. The center of the screw connector 7 and the plug part 10 is provided with an internal thread that is adapted to the bidirectional long screw 5. The plug part 10 is adapted to the connecting hole 9. Two screw connectors 7 located on the same bidirectional long screw 5 can be close to or far from each other. A pair of extension plates are provided on one side of the guardrail 1. Each pair of adjacent extension plates forms a group. A connection notch 12 is provided between the two. The connection notch 12 is adapted to the connecting plate 8. A through hole 11 is provided on the extension plate. The through hole 11 is adapted to the plug part 10.

[0023] During installation, first, fix the first guardrail 1 to the ground using the base plate 2 and support rod 3. Then, insert the connecting plate 8 on the two guardrails 1 into the connecting notch 12. Next, use a wrench to turn the hexagonal fixing sleeve 6 clockwise. The double-ended long screw 5 rotates clockwise, forcing the two screw parts 7 on it to move away from each other, and gradually inserting the plug part 10 from the through hole 11 into the connecting notch 12. When the head of the plug part 10 protrudes from the top of the guardrail 1, the installation is complete. The operation is simple and easy to use.

[0024] In this embodiment, as Figure 4 and Figure 5 As shown, a positioning groove 14 is provided on the guardrail 1, and a positioning slide rod 13 adapted to the positioning groove 14 is fixed on the swivel joint 7. The positioning slide rod 13 can slide in the positioning groove 14. When the swivel joint 7 moves, the positioning slide rod 13 slides in the positioning groove 14, so that the swivel joint 7 moves stably and avoids shaking or rotating with the bidirectional long screw 5, which has the function of limiting the movement.

[0025] The implementation principle of the landslide and rockfall buffer protection device in this application embodiment is as follows: During installation, the first guardrail 1 is first fixed to the ground by the fixed base plate 2 and the support rod 3. Then, the connecting plate 8 on the two guardrails 1 is inserted into the connecting notch 12. Then, the hexagonal fixing sleeve 6 is turned clockwise with a wrench. The two-way long screw 5 is rotated clockwise to force the two screw connectors 7 on it to move away from each other, and the plug part 10 is gradually inserted into the connecting notch 12 from the through hole 11. When the head of the plug part 10 is exposed from the top of the guardrail 1, the installation is completed. The operation is simple and easy to use.
