[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 The present invention provides a technical solution, including the following embodiments:

[0025] Example 1

[0026] Combination Figure 1 and Figure 2 As shown, this embodiment focuses on the basic length adjustment mechanism of the adjustable pipeline crossing protection box.

[0027] Specifically, the protective box includes a D-shaped box 1 with a curved surface and a flat surface to ensure structural continuity and load-bearing strength. The curved surface of the D-shaped box 1 is used for vehicle rolling, while the flat surface is used to conform to the ground for support. A D-shaped component 2 is slidably installed inside the D-shaped box 1, and the user can continuously adjust the effective length of the protective box by pulling or pushing the D-shaped component 2. An auxiliary plate 3 is fitted onto the outer wall of the extended D-shaped component 2, and its curved surface matches the curved surface of the D-shaped box 1 to form a smooth transition and avoid bumps when vehicles roll over it. A first base plate 31 and a second base plate 32, hinged at both ends of the auxiliary plate 3, support the bottom of the D-shaped component 2, providing a stable support base for the drop between the extended part and the ground. When the D-shaped component 2 extends, the user can select an appropriate number of auxiliary plates 3 for installation as needed. The sides of the auxiliary plates 3 fit together to further enhance the support and the continuity between the curved surfaces. When the road length changes, the user pushes the D-shaped component 2 to slide it out of the D-shaped box 1, and the auxiliary plates 3 expand outward accordingly. The first base plate 31 and the second base plate 32 are flipped to the bottom of the D-shaped piece 2 and fit against the ground, forming a stable support. The curved surface matching design ensures even pressure distribution when vehicles pass over it, protecting the pipelines running through the D-shaped piece 2 from damage. This sliding method allows for length adjustment and adapts to different road surface length requirements, avoiding instability caused by splicing. The hinged base plate design simplifies the installation process, allowing for quick deployment without additional tools. The number of auxiliary plates 3 can be selected according to the actual road surface for splicing and installation.

[0028] Example 2

[0029] Combination Figure 3 As shown, this embodiment optimizes the arrangement of the auxiliary board 3 to enhance the coverage area, based on embodiment one.

[0030] Specifically, there are multiple auxiliary plates 3, and the sides of the multiple auxiliary plates 3 fit together to form a tight array. The D-shaped component 2 has slots 22 arranged in a linear array. The protrusions 33 on the auxiliary plates 3 are movably positioned within the slots 22 for precise positioning. This positioning method ensures effective and stable splicing between the multiple auxiliary plates 3, preventing the auxiliary plates 3 from sliding on the outer wall of the D-shaped component 2 and affecting the splicing continuity. When the D-shaped component 2 extends, the user can install multiple auxiliary plates 3 sequentially. Each auxiliary plate 3 is fixed in position by the engagement of the protrusions 33 with the slots 22, ensuring overall alignment. The first base plate 31 and the second base plate 32 are hinged to adapt to uneven ground, providing uniform support. The user slides the D-shaped component 2 to the target position according to the pipeline length requirements, and then slides the multiple auxiliary plates 3 into the slots 22. The engagement of the protrusions 33 with the slots 22 prevents the auxiliary plates 3 from shifting, and the fitting sides of the multiple auxiliary plates 3 distribute pressure, forming a continuous protective curved surface. The multi-auxiliary plate (3) design significantly expands the protection range, making it suitable for long-distance pipeline crossing scenarios. The slot 22 and the protrusion 33 provide modular installation, ensuring accurate positioning of the auxiliary plate 3 and reducing installation errors. This synergistic support enhances overall stability, prevents local deformation, and extends service life. The auxiliary plate 3 is detachable and stackable, saving space.

[0031] Example 3

[0032] Combination Figure 4 As shown, this embodiment introduces a side plate 11 and a through slot 12 to improve locking reliability.

[0033] Specifically, the end of the D-shaped box 1 is provided with a side plate 11, and the side plate 11 has a through groove 12 corresponding to the slot 22. The protrusion 33 provided on the auxiliary plate 3 is movably disposed in the through groove 12 and the slot 22 to achieve double fixation. The side plate 11 is fitted into the receiving groove 34 opened on the auxiliary plate 3, and the protrusion 33 is fixedly installed on the inner wall of the receiving groove 34 to form a tight fit. The protrusion 33 and the auxiliary plate 3 are an integral structure. When the D-shaped part 2 is adjusted into place, the protrusion 33 is simultaneously embedded in the through groove 12 and the slot 22 to prevent the auxiliary plate 3 from loosening under the pressure of a vehicle. At the same time, the D-shaped box 1 and the D-shaped part 2 are locked. In use, after the user puts the D-shaped part 2 in place, the auxiliary plate 3 is attached to the D-shaped part 2, and the protrusion 33 passes through the through groove 12 of the side plate 11 and is engaged in the slot 22. The fitting of the side plate 11 with the receiving groove 34 enhances lateral stability, while the through groove 12 guides the protrusion 33 for precise positioning, ensuring a secure lock between the D-shaped box 1 and the D-shaped part 2. This method provides additional locking points for the side plate 11 and the through groove 12, significantly enhancing vibration and shock resistance. The receiving groove 34 design simplifies the alignment process and reduces installation complexity.

[0034] Example 4

[0035] This embodiment integrates the base plate connection mechanism and cable management function to improve practicality and convenience.

[0036] Specifically, the buckle 35 on the first base plate 31 is movably mounted within the slot 36 on the second base plate 32, enabling quick connection and fixation of the base plates. A cable management plate 21 is provided on the D-shaped component 2 to organize and secure passing pipelines, preventing them from becoming messy or shifting. The curved surface of the auxiliary plate 3 matches the curved surface of the D-shaped box 1, ensuring a smooth transition in the cable management plate 21 area. After the D-shaped component 2 is in place, the user unfolds the first base plate 31 and the second base plate 32, connecting the base plates by engaging the buckle 35 with the slot 36. The cable management plate 21 provides cable positioning, preventing cable twisting. The auxiliary plate 3 supports the overall structure, and its curved design ensures that the pipelines are not compressed when vehicles pass over it. This method allows for quick connection of the buckle 35 and the slot 36, reducing installation time and improving efficiency. The integrated design of the cable management plate 21 eliminates the need for additional cable management devices, keeping the pipelines neat and safe. The base plate connection enhances bottom stability.

[0037] Working principle: Users can continuously adjust the effective length of the protective box by pulling or pushing the D-shaped component 2 to adapt to different road surface requirements. The auxiliary plate 3 is fitted onto the outer wall of the extended D-shaped component 2, and its curved surface matches the curved surface of the D-shaped box 1 to form a smooth transition, avoiding bumps when vehicles run over it. The first base plate 31 and the second base plate 32, which are hinged at both ends of the auxiliary plate 3, are respectively supported at the bottom, providing a stable foundation for the extended part, ensuring uniform pressure distribution, and protecting the pipeline from damage. When it is necessary to expand the coverage area, multiple auxiliary plates 3 are connected to each other on the sides to form an array. The slots 22 on the D-shaped component 2 cooperate with the protrusions 33 on the auxiliary plate 3 to achieve precise positioning and modular installation, enhancing overall stability.

[0038] To further enhance locking reliability, a through groove 12 is provided on the side plate 11 at the end of the D-shaped box 1, and a protrusion 33 is movably disposed within the through groove 12 and the slot 22. The side plate 11 is fitted into the receiving groove 34 of the auxiliary plate 3 to prevent the auxiliary plate 3 from loosening under vehicle pressure, thereby enhancing vibration and impact resistance. Finally, the first base plate 31 and the second base plate 32 are quickly connected by the fastening of the buckle 35 and the buckle slot 36. The cable management plate 21 on the D-shaped part 2 organizes and fixes the passing pipelines, avoiding pipeline clutter and ensuring the bottom plate connection enhances bottom stability. The integrated cable management function improves practicality and convenience.
