Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a spliced ​​isolation net for road maintenance. Background Technology

[0002] In routine maintenance, renovation, or emergency repair work on urban roads and highways, temporary isolation facilities need to be set up around the work area to ensure the safety of construction workers and effectively guide traffic flow. Currently, commonly used isolation facilities mainly include water-filled barriers, crash barriers, and traditional metal safety nets.

[0003] Traditional metal safety barriers typically consist of posts and metal mesh panels. The posts are mounted on a base and are usually installed by drilling holes in the road surface and fixing the posts to the road surface with expansion bolts, which damages the road structure. Alternatively, a pit can be dug in the ground and the posts can be poured into a concrete foundation. Then, the posts are fixed to the safety barrier unit with 2-4 fastening bolts. The assembly and disassembly process is relatively cumbersome, time-consuming, and labor-intensive, making it relatively inconvenient.

[0004] Existing isolation devices also rely on hooks and other structures for connection. For example, Chinese utility model patent CN215859446U discloses a smart building construction security device. Its technical solution includes a main body, hook-and-loop connection structures, a movable protective mechanism, and a threaded fixing mechanism. Hook-and-loop connection structures are located on both sides of the main body, a movable protective mechanism is connected to one outer wall of the main body, and a threaded fixing mechanism is connected to the bottom of the main body. In this smart building construction security device, the base and extended legs provide support and stability to the overall equipment. During installation, the operator can further enhance the overall structural stability through the threaded fixing mechanism. However, this structure also suffers from problems such as cumbersome assembly and disassembly, being time-consuming and labor-intensive, and relatively inconvenient.

[0005] Therefore, there is a need to design a modular safety net for road maintenance that can effectively solve existing problems. Utility Model Content

[0006] To address the problems of existing methods that damage road structures by drilling holes or pouring concrete to fix posts, and the cumbersome, time-consuming, and inconvenient process of fixing and splicing posts to the isolation net units with bolts, this utility model provides a spliced ​​isolation net for road maintenance.

[0007] To achieve the objectives of this utility model, the technical solution adopted is as follows: A modular safety barrier for road maintenance includes a safety barrier unit and a support mechanism, with a support mechanism on each side of the safety barrier unit. The support mechanism includes a splicing assembly comprising a C-shaped insert, a hollow block, a straight plate, a locking rod, a vertical pole, and a movable plate. The movable plate is located inside the hollow block. The hollow block is located on the side wall of the C-shaped insert. The straight plate is located above the C-shaped insert and the hollow block, and a locking rod extends downward from one bottom end of the straight plate, with its bottom passing through the top of the C-shaped insert and extending into the interior of the C-shaped insert. A vertical pole extends downward from the other bottom end of the straight plate, with its bottom passing through the top of the hollow block and extending downward into the interior of the hollow block. The bottom of the vertical pole inside the hollow block is fixedly connected to the top of the movable plate. The safety barrier unit includes an insert connected to the C-shaped insert.

[0008] Based on the above technical solution, further, an elastic element is provided inside the hollow block, with the bottom end of the elastic element fixedly connected to the bottom of the hollow block and the top end of the elastic element fixedly connected to the bottom end face of the movable plate.

[0009] Based on the above technical solution, the isolation net unit is further composed of a net frame and a metal mesh, with the metal mesh fixedly installed inside the net frame and the inserts installed on the outer side wall of the net frame.

[0010] Based on the above technical solution, further, the side wall of the insert block is provided with a sliding groove, and the inner side wall of the C-shaped insert plate is provided with a sliding rail, and the sliding rail and the sliding groove are slidably engaged.

[0011] Based on the above technical solution, a locking hole is further provided on the top of the insertion block, and the locking hole matches the locking rod.

[0012] Based on the above technical solution, the support mechanism further includes a column and a base, with the column mounted on the base and the C-shaped insert plate mounted on the side wall of the column.

[0013] Based on the above technical solution, the base is further provided with a water inlet and a water outlet, and both the water inlet and the water outlet are threaded with bottle caps.

[0014] Furthermore, based on the above technical solution, the base is a hollow structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are specifically reflected in: The hollow base of this invention is lightweight and easy to transport. After being filled with water, the hollow base becomes stable, eliminating the need for drilling or pouring on the road surface and avoiding damage to the road structure. The splicing components allow the inserts to be quickly locked into the C-shaped inserts, thus facilitating the splicing of the posts and the isolation net units. Compared to the traditional method of using 2-4 fastening bolts to fix the posts and the isolation net units, this method saves time and effort, and makes splicing and disassembly simpler and more convenient.

[0018] The present invention will be further described and illustrated below with reference to the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly, provided that there is no mutual conflict.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0020] In the description of this utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected, i.e., there is an intermediate element. Conversely, when an element is said to be "directly" connected to another element, there is no intermediate element.

[0021] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0022] Example Combination Figures 1-4 As shown, this embodiment provides a spliced ​​isolation net for road maintenance, including an isolation net unit 1 and a support mechanism, and a support mechanism is provided on each side of the isolation net unit 1; the support mechanism includes a splicing component 2, which splices the support mechanism and the isolation net unit 1 together.

[0023] In this embodiment, the splicing assembly 2 includes a C-shaped insert plate 5, a hollow block 7, a straight plate 8, a locking rod 10, a vertical rod 9, and a movable plate 18. The movable plate 18 is disposed inside the hollow block 7 and is slidably connected to the inner sidewall of the hollow block 7. The sidewall of the C-shaped insert plate 5 is provided with the hollow block 7. The straight plate 8 is disposed above the C-shaped insert plate 5 and the hollow block 7. The bottom end of the straight plate 8 extends downward with a locking rod 10. The bottom of the locking rod 10 passes through the top of the C-shaped insert plate 5 and extends into the interior of the C-shaped insert plate 5. The other bottom end of the straight plate 8 extends downward with a vertical rod 9. The bottom of the vertical rod 9 passes through the top of the hollow block 7 and extends downward into the interior of the hollow block 7 and is fixedly connected to the top of the movable plate 18. It should be noted that both the vertical rod 9 and the locking rod 10 can rotate freely. Furthermore, an elastic element is provided inside the hollow block 7. The elastic element is preferably a return spring 17. The bottom end of the return spring 17 is fixedly connected to the bottom of the hollow block 7, and the top end of the return spring 17 is fixedly connected to the bottom end face of the moving plate 18.

[0024] In this embodiment, the isolation net unit 1 is composed of a net frame 19 and a metal mesh 20. The metal mesh 20 is fixedly installed inside the net frame 19 and can effectively isolate the road during maintenance. An insert 6 is provided on the outer wall of the net frame 19, and the insert 6 is slidably connected to the C-shaped insert plate 5. Furthermore, the insert 6 has a sliding groove 15 on its side wall and a sliding rail 14 on its inner side wall. The sliding rail 14 slides in conjunction with the sliding groove 15, and the sliding groove 15 serves as a limiting position. The top of the insert 6 also has a locking hole 16, which is used to match the locking rod 10. It should be noted that the locking rod 10 can rotate freely within the locking hole 16.

[0025] Specifically, the working principle of splicing component 2 and isolation net unit 1 is as follows: Lift the isolation net unit 1 and insert the plug 6 into the corresponding C-shaped insert plate 5. Then, grasp the straight plate 8 and pull it upwards while rotating it around the upright 9. The straight plate 8 is pulled upwards, which in turn drives the upright 9 and the locking rod 10 to rise. At this time, the return spring 17 is in a stretched state. The rotation of the straight plate 8 around the upright 9 causes the locking rod 10 to rotate above the locking hole 16. Slowly lower the straight plate 8. At this time, the return spring 17 rebounds and resets. The locking rod 10 moves down, passes through the top of the C-shaped insert plate 5, and inserts into the locking hole 16 to reset, thereby locking the plug 6 into the C-shaped insert plate 5. It should be noted that the number of C-shaped insert plates 5 can be set according to actual needs, but at least one must be set, as shown in the reference. Figures 2-3 As shown, two C-shaped insert plates 5 are provided on the same side wall of the same column 4, which are distributed vertically. Similarly, the number of insert blocks 6 that connect with the C-shaped insert plates 5 is consistent with the number of C-shaped insert plates 5, and their positions correspond to each other to ensure installation accuracy.

[0026] In this embodiment, the support mechanism also includes a column 4 and a base 3. The column 4 is installed on the top of the base 3, and the C-shaped insert 5 is installed on the side wall of the column 4. In order to save manufacturing costs and facilitate transportation, the base 3 is preferably designed as a hollow structure. At the same time, in order to further improve the stability of the support, the column 4 is preferably installed at the center of the top of the base 3 to ensure that the base 3 is evenly weighted. Furthermore, the base 3 is provided with a water inlet 11 and a water outlet 12. Preferably, the water inlet 11 is located on the top of the base 3, and the water outlet 12 is located on the side wall of the base 3. Both the water inlet 11 and the water outlet 12 are threaded with bottle caps 13. Specifically, by unscrewing the bottle cap 13 of the water inlet 11, water is injected into the hollow base 3 to increase the weight, thereby providing sufficient stability to resist wind or accidental collisions.

[0027] The above are merely embodiments of this utility model, described in a relatively specific and detailed manner, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
