Description

Technical Field

[0001] This utility model relates to the field of highway slope protection technology, and in particular to a quick-connect component and protection device for highway slope protection netting. Background Technology

[0002] Slope protection involves covering and wrapping various types of flexible netting around the slopes or rocks to limit weathering and erosion of the slope's rock and soil, as well as preventing rockfalls and controlling the movement of falling rocks within a certain range. This effectively ensures road safety. Retaining walls are a common technique in slope protection, facilitating highway protection and reducing the occurrence of dangerous situations such as rockfalls.

[0003] The protective nets used in existing protective devices mostly use metal mesh for interception and restraint to reduce the occurrence of dangers. The metal mesh is fixed to the mounting pole by welding. When it is damaged, it needs to be replaced as a whole. Disassembly and replacement are time-consuming, labor-intensive, costly, and have relatively low work efficiency.

[0004] Therefore, in order to address the above problems, a quick-connect component and protective device for highway slope protection netting is proposed to solve these problems. Utility Model Content

[0023] like Figures 2 to 6 As shown, a quick-connect component for highway slope protection netting includes an installation rod 1, a hook 2, and a stop bar 4. The installation rod 1 has installation grooves 11 at both the top and bottom, which pass through the installation rod 1. The bottom wall of the installation groove 11 is horizontally rotatably connected to one end of the hook 2. The bottom wall of the installation groove 11 has a sliding groove 111 along the plane perpendicular to the protection netting 5. The stop bar 4 is installed in the sliding groove 111. The free end of the hook 2 rotates to secure the protection netting 5 until the bottom of the stop bar 4 self-locks with the stop bar 4.

[0024] By setting hooks 2 and stops 4, it is easy to connect with the protective net 5. Its structure is simple and easy to operate, enabling safe and fast installation and removal of the protective net 5, improving work efficiency. At the same time, it facilitates the transportation of the protective net 5 and the connecting parts, making it easy to reuse and achieve the goal of green construction, energy conservation and emission reduction.

[0025] In this embodiment, the slide 111 includes a first slide 1111 and a second slide 1112 that are connected to each other. The second slide 1112 is located close to the hook 2, and the first slide 1111 is located away from the hook 2.

[0026] Hook 2 is C-shaped, with its opening facing towards the mounting rod 1. The stop rod 4 includes a sliding rod 41, a first traction rod 42, and a second traction rod 43. The first traction rod 42 is slidably mounted within the second sliding groove 1112. A spring 7 is installed on the inner wall of the first sliding groove 1111, with one end of the spring 7 away from the inner wall of the first sliding groove 1111 connected to the first traction rod 42. The first traction rod 42 is vertically mounted on the sliding rod 41. The second traction rod 43 is connected to the first traction rod 42 along the length parallel to the sliding rod 41. The second traction rod 43 facilitates operation and pulling by the worker.

[0027] In this embodiment, a rotating shaft 6 is provided on the bottom wall of the mounting groove 11, and one end of the hook 2 is rotatably mounted on the bottom wall of the mounting groove 11 via the rotating shaft 6, while the other end is provided with a "V"-shaped card interface 21.

[0028] The bottom of the sliding rod 41 has a "V"-shaped tip, and the "V"-shaped tip is adapted to the locking interface 21 of the hook 2. The "V"-shaped locking interface 21 adapts to the "V"-shaped tip at the bottom of the sliding rod 41, improving the engagement between the sliding rod 41 and the hook 2, so that the two can be locked together and are not easy to come apart.

[0029] like Figure 1 As shown, a highway slope protection device includes the quick-connect component of the highway slope protection net as described in any of the above claims, and also includes a concrete pier 8, with the mounting rods 1 evenly spaced on the concrete pier 8.

[0030] When installing the protective net 5, first rotate the hook 2. After hooking the protective net 5, rotate the hook 2 to the bottom of the sliding rod 41. The "V"-shaped locking interface 21 at the end of the hook 2 presses against the "V"-shaped tip of the sliding rod 41, causing the sliding rod 41 to drive the first traction rod 42 to overcome the elastic force of the spring 7. Its "V"-shaped tip is locked into the locking interface 21 at the end of the hook 2, thus connecting the protective net 5 to the installation rod 1. When it is necessary to remove the protective net, push the second traction rod 43 to cause the first traction rod 42 to press against the spring 7, causing the sliding rod 41 to move and disengage from the "V"-shaped locking interface 21 at the end of the hook 2. At this time, rotate the hook 2 to separate the hook 2 from the protective net 5, thus completing the removal of the protective net 5.

[0031] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
