[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] Example 1

[0038] The present embodiment provides a safety isolation device for highway reconstruction and expansion construction, including an isolation unit 100, which includes a supporting vertical rod 1, a telescopic net 9 and a base 7. The number of the supporting vertical rods 1 is at least two groups, and a reserved groove 3 is provided on the opposite side of two adjacent supporting vertical rods 1, and a hinge seat 4 is slidably provided in the reserved groove 3; the two ends of the telescopic net 9 are respectively hinged to the hinge seats 4 of the two adjacent supporting vertical rods 1; the base 7 is provided at the bottom of the supporting vertical rod 1 and the two correspond one to one, and the height of the base 7 can be adjusted; when the number of the isolation units 100 is multiple groups, the supporting vertical rods 1 of adjacent isolation units 100 can be detachably connected; the isolation units 100 can be connected in sequence to form a strip shape, and the isolation units 100 can also be connected end to end to form a ring shape.

[0039] The utility model relates to a safety isolation device for highway reconstruction and expansion construction. The isolation unit 100 is used to isolate the construction area. The isolation unit 100 is connected to the telescopic net 9 by using the support vertical rod 1 to isolate the construction area, ensuring the support stability while isolating. The support vertical rod 1 is used to drive the telescopic net 9 to extend and contract, which can adapt to different isolation needs. The telescopic net 9 is hinged to the articulated seat 4, and the articulated seat 4 is slidably arranged in the reserved groove 3 of the support vertical rod 1, ensuring the flexible extension and contraction of the telescopic net 9; the support vertical rods 1 of adjacent isolation units 100 are detachable and connected, and multiple groups of isolation units 100 can be connected into a strip structure or a ring shape. The spliced structure can adapt to the isolation of different areas, thereby improving the adaptability of the device to the construction environment and scope.

[0040] In this specific embodiment, each group of isolation units 100 includes two supporting vertical rods 1, and the two supporting vertical rods 1 are connected by a telescopic net 9. According to the specifications of the isolation area, an appropriate number of isolation units 100 can be selected to connect into a strip-shaped isolation structure, or to form a ring-shaped isolation structure.

[0041] In this embodiment, the telescopic net 9 utilizes a parallelogram-shaped telescopic mechanism. Two hinged seats 4 are connected to each end of the telescopic net 9. The sliding direction of the hinged seats 4 is parallel to the vertical direction, ensuring the normal expansion and contraction of the telescopic net 9. The telescopic net 9 can be adjusted to the specifications of the isolation unit 100 to meet different isolation construction conditions. The parallelogram-shaped telescopic mechanism of the telescopic net 9 provides a simple structure and reliable telescopic movement. In other embodiments of the present invention, the telescopic net 9 can also utilize other structures, such as a mesh structure with a certain degree of deformation.

[0042] Specifically, the two support vertical rods 1 in each isolation unit 100 are provided with a first lock buckle 13 on the side of one support vertical rod 1 away from the telescopic net 9, and a second lock buckle 14 on the side of the other support vertical rod 1 away from the telescopic net 9. The first lock buckle 13 and the second lock buckle 14 can be rotatably connected using a lock buckle pin 16, and the relative rotation axis of the first lock buckle 13 and the second lock buckle 14 is parallel to the vertical direction. When two adjacent isolation units 100 are connected, the first lock buckle 13 on the support vertical rod 1 of the isolation unit 100 can be matched with the second lock buckle 14 on the support vertical rod 1 of the other isolation unit 100, and the lock buckle pin 16 can be used to achieve a rotational connection to accommodate isolation construction on non-straight sections. At the same time, it is convenient to connect the isolation units 100 to form a ring structure to isolate the construction area.

[0043] The first lock catch 13 is a concave structure, and the second lock catch 14 is a convex structure adapted to the first lock catch 13. Both the first lock catch 13 and the second lock catch 14 have lock holes adapted to the lock pin 16. After the first lock catch 13 and the second lock catch 14 are assembled, the lock pin 16 passes through the lock holes of the first lock catch 13 and the second lock catch 14 from top to bottom, thereby achieving a rotational connection between the first lock catch 13 and the second lock catch 14. The use of the first lock catch 13, the second lock catch 14, and the lock pin 16 to achieve a rotational connection between the isolation units 100 facilitates assembly and disassembly, reduces operational difficulty, and reduces the workload of the operator.

[0044] More specifically, the support vertical rod 1 is further provided with a hook rod 2, which is located on the same side as the hinge seat 4 and above the hinge seat 4. The hook rod 2 is used to hook the safety warning banner 10. By hooking the four corners of the safety warning banner 10 on the hook rod 2, a striking safety slogan is formed, which serves as a warning and educational purpose, reminding drivers and pedestrians to stay away from the construction area.

[0045] In this embodiment, the hook rod 2 includes a connecting portion and a hooking portion. The connecting portion is connected to the support vertical rod 1. The hooking portion is L-shaped. The first branch of the hooking portion is connected to the connecting portion. A gap is formed between the second branch of the hooking portion and the support vertical rod 1, so that the hanging loop of the safety warning banner 10 passes through the gap between the second branch and the support vertical rod 1, passes through the second branch, and is hooked on the first branch. The connection portion of the hook rod 2 facilitates its connection to the support vertical rod 1, and the L-shaped hooking portion is provided for hooking the hanging loop or hanging rope of the safety warning banner 10. This prevents the hanging loop or hanging rope of the safety warning banner 10 from slipping off the hooking portion, thereby improving the fixed stability of the safety warning banner 10.

[0046] The highway reconstruction and expansion construction safety isolation device of the present invention also includes a warning light 12, which is detachably connected to the support vertical rod 1; the installation of the warning light 12 can effectively enhance the nighttime warning function, making the highway reconstruction and expansion construction safety isolation device of the present invention more eye-catching in the dark, thereby reducing traffic accidents caused by vehicles due to poor visibility.

[0047] In addition, the outside of the supporting vertical pole 1 has a reflective structural layer to further enhance the warning effect. The reflective structural layer is made of reflective paint. In actual application, yellow reflective paint can be coated on the outside of the supporting vertical pole 1 to play an obvious warning role during the day.

[0048] In order to facilitate the disassembly and assembly of the warning light 12, the warning light 12 is connected to a mounting base 17. The warning light 12 is arranged at the top of the mounting base 17. The bottom of the mounting base 17 has an insertion rod. The top of the supporting vertical rod 1 has a slot 11 adapted to the insertion rod. The mounting base 17 is connected to the supporting vertical rod 1 by means of the insertion rod; the warning light 12 is connected to the supporting vertical rod 1 by means of the mounting base 17, which is easy to install and is arranged at the top of the supporting vertical rod 1 to enhance the warning effect.

[0049] In this embodiment, there are two sets of insertion rods, and the mounting base 17 can be connected to the support vertical rods 1 of two adjacent isolation units 100 by means of the insertion rods. The mounting base 17 can be used to install the warning light 12 at the connection between the two isolation units 100. In actual application, the installation position of the warning light 12 can also be selected according to specific working conditions to meet different warning requirements.

[0050] Furthermore, the base 7 is connected to a threaded sleeve 19 and an adjusting screw 20. The threaded sleeve 19 is fixed to the base 7, and the adjusting screw 20 is threadedly connected to the threaded sleeve 19. The bottom of the adjusting screw 20 can contact the road surface, and the top of the adjusting screw 20 is connected to the turning handle 18. The turning handle 18 drives the adjusting screw 20 to rotate, thereby adjusting the relative position of the threaded sleeve 19 and the adjusting screw 20, thereby achieving the purpose of adjusting the height of the base 7 in the vertical direction by using the threaded sleeve 19. In actual application, a support block with a large bottom area can be provided at the bottom of the adjusting screw 20 to enhance the support stability of the base 7.

[0051] At the same time, the bottom of the base 7 is also connected to a moving wheel 8 to facilitate the movement and installation of the isolation unit 100. The moving wheel 8 has a brake structure to ensure the stability of the isolation unit 100 during the isolation construction process and improve the working reliability of the device.

[0052] Example 2

[0053] This embodiment discloses a safety isolation device for highway reconstruction and expansion construction. In a specific embodiment, each set of isolation units 100 includes N vertical support rods 1. Adjacent vertical support rods 1 are connected by telescopic nets 9. The number of telescopic nets 9 is N-1 sets, where N is a natural number not less than 3. In practical applications, the specifications of the isolation units 100 can be adjusted according to actual isolation conditions to meet different construction isolation requirements, further enhancing the flexibility and adaptability of the safety isolation device for highway reconstruction and expansion construction.

[0054] It needs to be explained here that in order to achieve the connection between adjacent groups of isolation units 100, the support vertical rods 1 located at both ends of each group of isolation units 100, the support vertical rod 1 at one end is provided with one of the first lock buckle 13 and the second lock buckle 14, and the support vertical rod 1 at the other end is provided with the other one of the first lock buckle 13 and the second lock buckle 14, so as to ensure the smooth connection of the isolation units 100 of adjacent groups; and the support vertical rod 1 located in the middle is provided with reserved grooves 3 on both sides, and the first lock buckle 13 and the second lock buckle 14 may not be provided.

[0055] The other structures of the highway reconstruction and expansion construction safety isolation device of this embodiment are the same as those of the first embodiment and will not be described again here.

[0056] Example 3

[0057] This embodiment discloses a safety isolation device for highway reconstruction and expansion construction. Each isolation unit 100 includes two support vertical rods 1 at both ends. A chain 5 is provided on the side of one support vertical rod 1 away from the telescopic net 9. A chain hook 6 is also connected to the end of the chain 5. A buckle 15 compatible with the chain hook 6 is provided on the side of the other support vertical rod 1 away from the telescopic net 9. The chain hook 6 can be hooked and connected to the buckle 15. When multiple groups of isolation units 100 are connected, the chains 5 of the support vertical rods 1 of one isolation unit 100 in two adjacent isolation units 100 are hooked and connected to the buckles 15 of the support vertical rods 1 of the adjacent isolation unit 100 using the chain hook 6, thereby achieving a connection between the isolation units 100. At the same time, when the isolation unit 100 is transported and moved, the telescopic net 9 can be retracted, and then the chain 5 of the supporting vertical rod 1 at one end of each group of isolation units 100 is hooked and connected with the buckle 15 of the supporting vertical rod 1 at the other end, saving the space occupied by the isolation unit 100, facilitating the storage and transportation of the isolation unit 100, and further improving the flexibility and adaptability of the highway reconstruction and expansion construction safety isolation device of the utility model.

[0058] In actual application, the length of the chain 5 can be adjusted to meet the connection requirements of the isolation unit 100. At the same time, when the isolation unit 100 is stored and transported, the chain 5 can be used to wrap the telescopic net 9 around the contracted isolation unit 100, further facilitating the transportation and transfer of the isolation unit 100.

[0059] The other structures of the highway reconstruction and expansion construction safety isolation device of this embodiment are the same as those of the first embodiment and will not be described again here.

[0060] Example 4

[0061] This embodiment discloses a safety isolation device for highway reconstruction and expansion construction, and the device structure is the same as that of the first embodiment. When the device is used, the telescopic net 9 is pulled open to separate the two supporting vertical rods 1 of the isolation unit 100. When the supporting vertical rod 1 is pulled open, the hanging ropes at the four corners of the safety warning banner 10 are hung on the hook rod 2 to form a striking safety slogan logo, which plays a warning and educational role, reminding drivers and pedestrians to stay away from the construction area. A warning light 12 can be installed on the top between the two groups of isolation units 100 to strengthen the night warning, making the isolation device more eye-catching in the dark and reducing traffic accidents caused by vehicles due to poor visibility. The exterior of the supporting vertical rod 1 is coated with yellow reflective paint, which plays a significant warning role during the day. After the support vertical rods 1 are pulled apart, the telescopic net 9 is unfolded to form interception and isolation. The support vertical rods 1 are matched with the first lock buckle 13 and the second lock buckle 14, and the lock buckle pin 16 is used to plug in, so that the two groups of isolation units 100 can rotate relative to each other while forming a connection. Multiple support vertical rods 1 can form a continuous isolation structure, which can be surrounded and isolated according to the specific shape of the isolated area. Turn the handle 18, and the adjustment screw 20 is continuously rotated downward in the threaded sleeve 19 until it contacts the ground, acting as a support foot to prevent the device from sliding, ensuring stability under various ground conditions.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
