[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Example:
[0032] like Figures 1 to 10 As shown, an underground automatic roadblock comprises an underground box 1 and a roadblock box 4. The roadblock box 4 is assembled on the upper side of the buried box 1. Hydraulic cylinders 12 are fixed on both sides of the left and right sides of the buried box 1, and the upper ends of the hydraulic cylinders 12 are fixedly connected to the bottom surface of the roadblock box 4. A cavity groove 17 is opened on the upper side of the interior of the roadblock box 4. Two groups of roadblock boxes 6 are symmetrically accommodated in the cavity groove 17. Both groups of roadblock boxes 6 are provided with reversible roadblock plates 7, and the rear ends of the roadblock plates 7 are rotatably connected to the roadblock boxes 6 through pins. Multiple groups of thorn teeth 8 are evenly arranged on one side of the roadblock plate 7 close to the roadblock box 6. Two groups of first hydraulic rods 9 are symmetrically arranged on the left and right sides of the interior of the roadblock box 6, and the ends of the first hydraulic rods 9 are connected to the The roadblock box 6 is hinged, and the head end is hinged to the rear end of the roadblock plate 7. Multiple groups of second hydraulic rods 16 are arranged on the lower side of the interior of the roadblock box 4, and the two adjacent groups of second hydraulic rods 16 are arranged upside down. A slide groove 15 is opened at the bottom of the cavity groove 17, and a pull rod 11 is provided inside the slide groove 15. The upper end of the pull rod 11 is fixedly connected to the roadblock box 6, and the lower end thereof is fixedly connected to the output end of the second hydraulic rod 16. This design solves the problem that the existing underground roadblocks are bulky, which not only takes up a lot of storage space, but also increases the difficulty of transportation and handling. In addition, during the construction and installation process, a large area of road surface excavation is required, and the excavation amount is large, which not only destroys the road structure, but also increases the complexity and time-consuming nature of construction.
[0033] In this embodiment, limiting struts 13 are fixed to the bottom of the roadblock box 4 near the four corners, and limiting plates 14 are fixed to the inner wall of the buried box 1 near the four corners. The limiting struts 13 penetrate the limiting plates 14 and are slidably connected to them. This design, through the limiting struts 13 and the limiting plates 14, provides support and guidance for the roadblock box 4, providing stable guidance for the lifting and lowering of the roadblock box 6. This ensures that the roadblock box 4 slides smoothly along the predetermined trajectory during the lifting process, avoiding shaking or deviation, thereby ensuring the stability of the roadblock box 4.
[0034] In this embodiment, blocking plates 3 are installed on both sides of the roadblock box 4. These blocking plates 3 are triangular prism-shaped, and multiple groups of cone-shaped spikes 24 are provided on both the front and rear surfaces of the blocking plates 3. These blocking plates 3 form a physical barrier on both sides of the roadblock box 4. Together with the blocking plates 7, they extend the device's blocking path, increasing the width of the roadblock and its blocking range, thus enhancing its blocking effectiveness.
[0035] In this embodiment, the end of the barrier plate 3 near the barrier box 4 is fixedly connected to a support shaft 22. The distal end of the support shaft 22 is rotatably connected to the barrier box 4 via a shaft seat. A driven pulley 21 is mounted on the support shaft 22. A drive motor 20 is mounted within the barrier box 4. The output end of the drive motor 20 extends through the barrier box 4 and is mounted on a driving pulley 26. The driving pulley 26 is connected to the driven pulley 21 via a belt 25. This design, comprising the support shaft 22, the drive motor 20, the driven pulley 21, and the driving pulley 26, forms a drive system capable of rotating the barrier plate 3 and controlling its position. Driven by the drive motor 20, the driving pulley 26 drives the belt 25, which in turn drives the driven pulley 21, thereby automatically rotating the barrier plate 3. This automated control significantly improves the efficiency of deploying and retracting the barrier plate 3 and reduces the complexity and time-consuming manual operation.
[0036] In this embodiment, triangular side boxes 2 are welded to each side of the underground box 1. These side boxes 2 are designed to accommodate the barrier plates 3. These side boxes 2 accommodate the barrier plates 3, allowing them to be stored when not in use, reducing potential threats to surrounding personnel and objects.
[0037] In this embodiment, triangular notches 10 are provided on both the left and right sides of the underground box 1, and the positions of the notches 10 correspond to those of the side boxes 2. The notches 10 ensure that the barrier box 4 can be raised and lowered, preventing obstructions to the drive motor 20, support shaft 22, and other components during the raising and lowering process, thereby ensuring the normal operation of the barrier box 4.
[0038] In this embodiment, a bottom plate 23 is fixed to the bottom of the barrier plate 3, and the width of the bottom plate 23 is the same as the width of the side box 2. The design of the bottom plate 23 allows the barrier plate 3 to be completely hidden within the side box 2 when retracted, reducing safety hazards when the roadblock is not in use. At the same time, it can protect the barrier plate 3 from being directly run over by vehicles and other vehicles, which may cause damage to the barrier plate 3.
[0039] In this embodiment, a top plate 5 is fixed to the top of the roadblock box 4. The top plate 5 has the same external specifications as the underground box 1. This top plate 5 seals the top of the roadblock box 4 when not in use, forming a complete structure with the underground box 1, facilitating the passage of people and vehicles. It also protects the roadblock box 4 and increases its top load-bearing capacity, allowing it to withstand greater external pressure or weight, preventing damage caused by vehicles running over it.
[0040] In this embodiment, stop blocks 19 are fixedly mounted on both upper and lower end surfaces near the rear end surface of the roadblock box 6. Stop slots 18 matching the specifications of the stop blocks 19 are formed on both upper and lower sides of the inner wall of the cavity 17. The stop blocks 19 are inserted into the stop slots 18 and slidably connected thereto. The stop blocks 19 and stop slots 18 serve as a guide for the roadblock box 6, ensuring its accurate position within the cavity 17. This makes the movement of the roadblock box 6 smoother and more stable, avoids the risk of the roadblock box 6 accidentally falling out of the cavity 17 during movement, and improves the stability of the movement of the roadblock box 6.
[0041] The working principle of this kind of underground automatic roadblock is as follows: First, a groove for accommodating the roadblock is excavated on the road surface, the roadblock is installed underground, and the top surface of the top plate 5 is flush with the bottom surface. In the initial state, the roadblock box 4 is located inside the underground box 1, the roadblock box 6 is housed in the cavity slot 17, and the blocking plate 3 is housed in the side box 2. When the roadblock needs to be deployed, the hydraulic cylinder 12 is started to push the roadblock box 4 up until the bottom surface of the roadblock box 4 is higher than the road surface. At the same time, the second hydraulic rod 16 is started, pushing the pull rod 11 to slide in the slide 15, and then pushing the roadblock box 6 out of the cavity slot 17. Then the first hydraulic rod 9 starts to retract, pulling the rear end of the roadblock plate 7, causing the roadblock plate 7 to flip to a vertical state, and forming a roadblock through the roadblock plate 7 and the spikes 8 thereon, thereby achieving obstruction of the vehicle and the formed vehicle. As the barrier box 4 rises, it drives the blocking plates 3 on both sides to rise. Then the drive motor 20 starts, driving the support shaft 22 to rotate through the active pulley 26, belt 25 and driven pulley 21, thereby rotating the blocking plates 3 180 degrees, so that the bottom plate 23 is located at the bottom side, and the spikes 24 on it are exposed, forming an additional physical blocking barrier through the blocking plates 3.
[0042] When the roadblock needs to be retracted, the first hydraulic rod 9 starts to extend, pushing the rear end of the roadblock plate 7, causing the roadblock plate 7 to flip back to a horizontal state. The second hydraulic rod 16 starts to retract, pulling the pull rod 11 to slide in the slide 15, thereby pulling the roadblock box 6 back into the cavity slot 17. At the same time, the drive motor 20 starts in the reverse direction, driving the support shaft 22 to rotate through the active pulley 26, belt 25, and driven pulley 21, thereby flipping the barrier plate 3 to a state where the bottom plate 23 is on top. The hydraulic cylinder 12 starts in the reverse direction, pulling the barrier box 4 down until it is completely stored in the buried box 1, and the barrier plate 3 is stored in the side box 2.
[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
