Description

Technical Field

[0001] This utility model belongs to the field of traffic safety technology, specifically relating to a safety island for preventing collisions in underground cavern roads. Background Technology

[0002] Due to their inherent characteristics such as narrow spaces and poor lighting, underground tunnels are highly susceptible to collisions if drivers make mistakes or brakes fail. Currently available crash barriers have several limitations in meeting the specific needs of underground tunnels. For example, traditional crash barriers have limited impact absorption capacity, easily causing severe damage to vehicles and potentially serious injuries to occupants. Furthermore, traditional crash barriers are difficult to repair, requiring significant time and resources for maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a safety island for underground cavern roads to solve the above problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a safety island for road collision prevention in underground caverns, including a base assembly, on which an installation frame is fixedly connected, and a plurality of tires arranged in a rectangular array are placed inside the installation frame;

[0006] The base assembly includes a rectangular frame, on which a detachable blocking frame is vertically mounted, and a detachable diagonal brace is installed between the rectangular frame and the blocking frame.

[0007] The mounting frame is fixedly connected to the blocking frame, and the tire covers the front of the blocking frame.

[0008] The aforementioned underground cavern road safety island uses a base component as its foundation. The core component, a rectangular frame, has a steel mesh fixedly connected to its bottom, which provides a basic support framework for the overall structure.

[0009] The T-shaped grooves on both sides of the rectangular frame cooperate with the T-shaped sliders on both sides of the blocking frame, allowing the blocking frame to slide on the rectangular frame. This detachable connection design facilitates the maintenance and replacement of various components in the future.

[0010] The connecting blocks at both ends of the diagonal brace are inserted into slot one and slot two on the rectangular frame and the blocking frame, respectively, which further enhances the connection strength between the blocking frame and the rectangular frame, making the entire base assembly form a stable triangular support structure.

[0011] The tires, arranged in a rectangular array within the mounting frame, form a flexible buffer layer. When a vehicle collides with the safety island, the tires have good elasticity and can deform instantly upon impact. Through their elastic deformation, they absorb some of the vehicle's impact energy, providing initial cushioning and shock absorption, and reducing the direct impact force on the vehicle.

[0012] The aluminum plate not only provides a fixed support frame for the tire, ensuring that the tire will not shift when it is hit, but also helps to absorb impact energy to a certain extent. Together with the tire, it forms a multi-level buffer system to further improve the buffering effect.

[0013] Preferably, the rectangular frame has grooves on both sides, and sliders are slidably connected in the grooves. The two sliders are fixedly connected to the two sides of the blocking frame.

[0014] Preferably, both the groove and the slider are T-shaped.

[0015] Preferably, a support leg is fixedly connected to the back of the blocking frame, the support leg is inclined to the blocking frame, and the lower end of the support leg is flush with the bottom of the rectangular frame.

[0016] Preferably, the rectangular frame and the blocking frame are respectively provided with slot one and slot two, and the two ends of the diagonal brace are respectively fixedly connected to connecting blocks, and the two connecting blocks are respectively inserted into slot one and slot two.

[0017] Preferably, a warning light is fixedly connected to the blocking frame.

[0018] Preferably, the mounting frame includes two fixing plates, which are fixedly connected to both sides of the blocking frame. Multiple aluminum plates are horizontally fixed between the two fixing plates, and a tire is placed between two adjacent aluminum plates.

[0019] Preferably, a steel mesh is fixedly connected to the bottom of the rectangular frame, and a counterweight is placed on the steel mesh.

[0020] Preferably, the counterweight is a sandbag or a concrete block.

[0021] Preferably, the surface of the base assembly is coated with a red and white reflective paint.

[0022] The beneficial effects are:

[0023] 1. By combining the flexible tire buffer layer with the aluminum plate auxiliary support structure, the impact energy of the vehicle can be efficiently absorbed. When a vehicle collision occurs, the elastic deformation of the tire and the synergistic effect of the aluminum plate can significantly reduce the impact force on the vehicle and people. Compared with traditional anti-collision facilities, it can significantly reduce the degree of vehicle damage and the risk of personal injury in an accident, providing reliable protection for driving safety in underground tunnel roads;

[0024] 2. The modular and detachable structural design is adopted. The rectangular frame and the blocking frame are connected by the cooperation of sliding grooves and sliders, and the insertion of diagonal braces. The mounting frame and the blocking frame are also fixedly connected. Each component can be transported and installed independently, which greatly simplifies the installation process, reduces the installation difficulty and construction cost. In the later maintenance process, if a component is damaged, it can be directly disassembled and replaced without large-scale repair of the entire safety island. This effectively improves maintenance efficiency, reduces maintenance costs, and extends the service life of the safety island.

[0025] 3. The dual warning design of warning lights and reflective paint can improve the visibility and recognition of the safety island from different angles in the dimly lit environment of underground caverns, effectively reminding drivers to pay attention to safety and reducing collision accidents caused by failure to notice the safety island in time.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] See Figures 1-4 As shown, this utility model provides a safety island for underground cavern roads, including a base assembly 1, an installation frame 2 fixedly connected to the base assembly 1, and a plurality of tires 3 arranged in a rectangular array placed inside the installation frame 2;

[0035] The tires 3, arranged in a rectangular array within the mounting frame 2, form a flexible buffer layer. When a vehicle collides with the safety island, these tires 3 are the first parts to come into contact with it.

[0036] Tire 3 has good elasticity and can deform at the moment of impact. It absorbs part of the impact energy of the vehicle through its own elastic deformation, playing a preliminary role in buffering and shock absorption, reducing the direct impact force on the vehicle. The tire is made from recycled tires.

[0037] The base assembly 1 includes a rectangular frame 5, a detachable blocking frame 6 is vertically mounted on the rectangular frame 5, and a detachable diagonal brace 7 is installed between the rectangular frame 5 and the blocking frame 6.

[0038] The mounting frame 2 is fixedly connected to the blocking frame 6, and the tire 3 covers the front of the blocking frame 6.

[0039] A fire extinguisher is placed on the side of the base assembly 1 for emergency use.

[0040] As an optional implementation, the rectangular frame 5 has grooves 16 on both sides, and sliders 17 are slidably connected in the grooves 16. The two sliders 17 are fixedly connected to the two sides of the blocking frame 6.

[0041] Both the groove 16 and the slider 17 are T-shaped.

[0042] The back of the blocking frame 6 is fixedly connected to a support leg 8. The support leg 8 is inclined to the blocking frame 6, and the lower end of the support leg 8 is flush with the bottom of the rectangular frame 5.

[0043] The supporting leg 8 and the rectangular frame 5 form a stable triangular structure. When a vehicle collides with the safety island, the supporting leg 8 can disperse the impact force, preventing the barrier frame 6 from tilting or collapsing due to uneven force distribution. This ensures that the entire safety island remains stable when subjected to impact, without displacement or overturning, laying the foundation for the normal functioning of subsequent buffer protection.

[0044] The rectangular frame 5 and the blocking frame 6 are respectively provided with slot 14 and slot 2 15. The two ends of the diagonal brace 7 are respectively fixedly connected to connecting blocks 13, and the two connecting blocks 13 are respectively inserted into slot 14 and slot 2 15.

[0045] The connecting blocks 13 at both ends of the diagonal brace 7 are inserted into slot 14 and slot 2 15 on the rectangular frame 5 and the blocking frame 6, respectively, which further enhances the connection strength between the blocking frame 6 and the rectangular frame 5, making the entire base assembly form a stable triangular support structure, effectively improving the safety island's ability to resist vehicle impacts.

[0046] Warning lights 4 are fixedly connected to the barrier 6.

[0047] The mounting frame 2 includes two fixing plates 9, which are fixedly connected to both sides of the blocking frame 6. Multiple aluminum plates 10 are horizontally fixedly connected between the two fixing plates 9, and tires 3 are placed between two adjacent aluminum plates 10.

[0048] The aluminum plate 10 not only provides a fixed support frame for the tire 3, ensuring that the tire 3 will not shift arbitrarily when it is impacted, but also helps to absorb impact energy to a certain extent. Together with the tire 3, it forms a multi-level buffer system to further improve the buffering effect.

[0049] A steel mesh 11 is fixedly connected to the bottom of the rectangular frame 5, and a counterweight 12 is placed on the steel mesh 11.

[0050] The counterweight 12 is made of sandbags or concrete blocks. The sandbags or concrete counterweight 12 placed on the surface of the steel mesh 11 enhance the stability and impact resistance of the safety island by increasing its weight, so that it can remain stable when hit by a vehicle and is not easy to shift or tip over.

[0051] The surface of the base component 1 is coated with red and white reflective paint.

[0052] Using the above structure, the base component 1 serves as the foundation of the anti-collision safety island, and the steel mesh 11 fixedly connected to the bottom of its core component rectangular frame 5 provides a basic support frame for the overall structure.

[0053] The T-shaped grooves 16 on both sides of the rectangular frame 5 cooperate with the T-shaped sliders 17 on both sides of the blocking frame 6, so that the blocking frame 6 can be slidably installed on the rectangular frame 5. This detachable connection design facilitates the maintenance and replacement of each component in the later stage.

[0054] The connecting blocks 13 at both ends of the diagonal brace 7 are inserted into slot 14 and slot 2 15 on the rectangular frame 5 and the blocking frame 6, respectively, which further enhances the connection strength between the blocking frame 6 and the rectangular frame 5, so that the entire base assembly forms a stable triangular support structure.

[0055] The tires 3, arranged in a rectangular array within the mounting frame 2, form a flexible buffer layer. When a vehicle collides with the safety island, the tires 3 have good elasticity and can deform instantly upon impact. Through their own elastic deformation, they absorb part of the vehicle's impact energy, playing a preliminary buffering and shock-absorbing role, and reducing the direct impact force on the vehicle.

[0056] The aluminum plate 10 not only provides a fixed support frame for the tire 3, ensuring that the tire 3 will not shift arbitrarily when it is impacted, but also helps to absorb impact energy to a certain extent. Together with the tire 3, it forms a multi-level buffer system to further improve the buffering effect.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
