Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides an easily adjustable highway bridge construction fence, which consists of components such as pile 1, winding assembly 2, protective assembly 3 and positioning bolts 5, and achieves significant advantages such as flexible adjustment of the protection range, simple and quick installation and disassembly, and strong overall stability.

[0025] As attached Figure 5 As shown: The pile 1 serves as the basic support structure of the construction fence, consisting of a mounting base 101 and a post 102. The mounting base 101 and post 102 are made of high-strength metal materials (such as steel). The post 102 is firmly connected to the mounting base 101 by welding or bolting, ensuring connection strength. Several connecting hooks 103 are fixed to the surface of the post 102 by welding or casting. The number and position of the connecting hooks 103 are designed according to the connection requirements of the protective net 301, ensuring that the protective net 301 can be firmly connected to the pile 1, thereby clearly defining the protective boundary of the construction fence and effectively preventing unauthorized personnel from entering the construction area. The mounting base 101 is provided with mounting holes 6, which can be firmly fixed to the ground using expansion bolts, ground nails, and other fasteners, providing a stable support foundation for the entire construction fence.

[0026] As attached Figure 3 To be continued Figure 4 As shown: The winding assembly 2 is installed between two adjacent uprights 1, including a base 201 and a winding rod 202. The support seat 2011 of the base 201 is made of metal material through machining processes (such as turning, milling, etc.), and has mounting holes 6. The support seat 2011 can be fixed to the ground by expansion bolts, ground nails and other fasteners to provide stable support for the construction fence.

[0027] The winding shaft 2021 of the winding rod 202 is made of metal and is mounted on the support base 2011 via bearings. Two positioning discs 2022 are fixedly sleeved at its lower end. The upper end of the winding shaft 2021 has a hanging ring 2023 fixed by welding or casting. Each positioning disc 2022 has three insertion holes, each containing a positioning bolt 5. The support base 2011 has several positioning holes 2012, the number of which is n times the number of insertion holes in the positioning discs 2022 (n is a positive integer, e.g., n=2). When adjusting the protective net 301, the positioning holes 2012 and the insertion holes in the positioning discs 2022 work together. The positioning bolts 5 can be inserted into the corresponding positioning holes 2012 and the insertion holes in the positioning discs 2022, achieving precise positioning of the rotation angle of the winding shaft 2021. This ensures that the protective net 301 remains stable after adjustment, meeting the protection requirements of different construction sites.

[0028] As attached Figure 2 As shown: The protective component 3 is connected between the winding shaft 2021 and the post 1, and includes a retractable protective net 301 with an overall length of 10m. The protective net 301 can be made of high-strength metal wire mesh or weather-resistant plastic mesh, and has metal connecting plates 302 at both ends that are fixed by welding or riveting to ensure sufficient strength and rigidity.

[0029] A connecting ring 303 and a steel wire rope 304 are welded onto the connecting plate 302. One side of the connecting ring 303 is fixedly connected to the hanging ring 2023 on the winding shaft 2021, while the other side is detachably connected to the connecting hook 103 on the post 1. This connection method is extremely simple, allowing workers to quickly connect the protective netting 301 on the winding shaft 2021 to the post 1 without the need for complex tools, significantly improving installation efficiency. Disassembly is simple: just reverse the operation, connecting the connecting ring 303 to the connecting hook 103, and the protective netting 301 can be easily removed, effectively reducing the time and labor costs required for fence installation and disassembly during construction. The steel wire rope 304 connects the two connecting plates 302, enhancing the structural stability of the protective netting 301 and preventing tensile deformation. The protective netting 301 not only prevents unauthorized personnel from entering the construction area but also allows for the display of warning signs, reminding passing vehicles and pedestrians to pay attention to construction safety, thus serving a safety warning function. The protective netting 301 can be retracted and extended by rotating the rewinding shaft 2021, which allows the protective range of the construction fence to flexibly adapt to various complex sites such as straight construction sections, curves, and irregular areas, greatly improving the applicability and flexibility of the fence.

[0030] As attached Figure 3 To be continued Figure 4As shown: Symmetrically distributed hooks 4 are welded or cast onto the reel 2021 and the post 102, serving as anchoring connection points. During construction, especially in windy conditions, the hooks 4 can be connected to ground nails or fixed structures via steel wire ropes, enhancing the fence's wind resistance and stability, and ensuring construction safety. Even in the event of strong winds or accidental vehicle collisions, the construction fence remains stable, preventing tilting or collapse, ensuring effective protection in various environments and guaranteeing construction safety.

[0031] Working Principle: First, by adjusting the number of posts 1 and retractable components 2, the fence can flexibly adapt to construction areas of different lengths and shapes. Posts 1 are fixed to the ground by mounting bases 101, and connecting hooks 103 on posts 102 are used to connect the protective netting 301, ensuring clear protection boundaries. Retractable components 2 are installed between adjacent posts 1, and their number can be increased or decreased according to the needs of the construction area, ensuring that the protective netting 301 can cover the entire construction area. When it is necessary to adjust the unfolded length of the protective netting 301, the retractable shaft 2021 is rotated to unfold or retract the protective netting 301 from the retracted state. Positioning bolts 5 are inserted into the corresponding positioning holes 2012 and the insertion holes of positioning discs 2022 to fix the position of the retractable shaft 2021, ensuring that the protective netting 301 remains stable after adjustment and will not loosen or shift due to external forces. During installation, simply hook the connecting ring 303 onto the connecting hook 103; disassembly is done by reversing the operation. The two ends of the protective net 301 are connected by steel wire ropes 304, which further enhances its structural stability and prevents the protective net 301 from deforming due to tension. When the wind is strong or additional stability is required, the hooks 4 can be connected to ground nails or nearby fixed buildings through steel wire ropes to enhance the overall wind resistance and impact resistance of the fence.
