Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of road traffic safety facilities, specifically to an anti-overturning structure for the divergence points of interchange ring road ramps. Background Technology
[0002] In modern transportation networks, interchanges serve as crucial nodes for traffic flow conversion between different road directions, and the traffic conditions at the junctions of ring road ramps and divergences are particularly complex. Because vehicles need to change lanes, decelerate, or accelerate at these points, driver errors and improper speed control can easily lead to vehicle rollovers or loss of control, causing serious traffic accidents that threaten the lives of passengers and drivers, as well as resulting in significant economic losses and traffic congestion.
[0003] Currently, common ramp protection measures mainly include ordinary metal guardrails and concrete crash barriers. While ordinary metal guardrails offer some cushioning, they are prone to deformation or even breakage when impacted by high-speed or heavy vehicles, making it difficult to effectively prevent vehicles from running off the road. Concrete crash barriers, although rigid enough to withstand vehicles running off the road, suffer from poor cushioning performance; the impact force generated instantly upon collision can easily lead to severe vehicle damage and secondary injuries to occupants. With the increasing traffic volume, providing an anti-overturning structure that combines high cushioning performance and structural stability at the branching points of interchange ring road ramps has become an urgent technical problem to be solved. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an anti-overturning structure for the divergence points of interchange ring road ramps.
[0005] The technical solution of this utility model is:
[0006] The anti-overturning structure for the divergence point of a grade-separated interchange ring road includes a base fixed to the ground. A vertical plate is hinged to the front top of the base via a hinge shaft. A diagonal brace plate for supporting the vertical plate is fixed to the top of the base via bolts. A support plate is located on the front side of the vertical plate. A damper is fixedly installed at each of the four corners of the front outer wall of the vertical plate. The support plate is fixedly connected to the piston rods of the four dampers. Several buffer springs are fixedly installed between the support plate and the vertical plate. A foamed aluminum buffer pad is fixedly installed on the front outer wall of the support plate, and a high-elasticity rubber buffer pad is fixedly installed in front of the foamed aluminum buffer pad. A top protective plate is installed on the top of the vertical plate. The base is fixed to the ground, and the hinge shaft enables the hinged installation of the vertical plate, which, together with the diagonal brace plate, forms a stable foundation structure. The dampers, buffer springs, foamed aluminum buffer pad, and high-elasticity rubber buffer pad on the front side of the vertical plate constitute a multi-stage buffer system, which can effectively absorb and disperse the energy generated by a vehicle impact, reducing the impact force on the vehicle and occupants. The top protective plate prevents the vehicle from rolling over, further enhancing safety. The overall structural design is reasonable, providing reliable protection in the event of a rollover or collision, reducing accident losses.
[0007] As a preferred technical solution, the diagonal brace is fixedly connected to the outer wall of the vertical plate by a plurality of fixing bolts, which are evenly spaced. Fixing the diagonal brace to the vertical plate with multiple equally spaced fixing bolts enhances the stability of the connection, ensures that the diagonal brace can effectively support the vertical plate, and improves the overall strength and impact resistance of the structure.
[0008] As a preferred technical solution, the vertical plate is installed in a vertical position, and can be rotated to a horizontal position after disassembly. The vertical plate can remain vertical during installation to provide protection, and can be rotated to a horizontal position after disassembly, facilitating transportation and storage, and improving the maintainability and practicality of the structure.
[0009] As a preferred technical solution, the front side of the high-elastic rubber buffer pad is provided with multiple waste tires. The waste tires are fixedly connected to the support plate by multiple long screws, which pass through two buffer pads. This further increases the number of buffer pads, utilizes the elasticity and deformation capacity of the waste tires to absorb more energy, and simultaneously realizes the reuse of waste resources, reducing costs.
[0010] As a preferred technical solution, a top protective pad is fixedly installed at the bottom of the top protective plate, and the top protective plate is connected to the vertical plate via a pin. The top protective pad at the bottom of the top protective plate enhances the protection of the vehicle, and the pin connection makes the installation and removal of the top protective plate more convenient, facilitating maintenance and replacement.
[0011] As a preferred technical solution, the insert shaft is plugged into both the vertical plate and the top protective plate. The cross-section of the insert shaft is a regular N-gon, and N≥6. This design prevents the insert shaft from rotating, ensures the connection stability between the top protective plate and the vertical plate, improves the reliability of the structure, and allows for adjustment of the angle of the top protective plate, increasing convenience during use.
[0012] As a preferred technical solution, a limiting screw is threaded onto one end of the insertion shaft, and a screw head is integrally formed on the outer wall of the limiting screw on the same axis. The limiting screw and screw head facilitate the limiting and fixing of the insertion shaft.
[0013] As a preferred technical solution, the base has several equally spaced fixing holes on both sides, and the screw head is a standard-sized screw head. The fixing holes on both sides of the base facilitate further fixing of the base to the ground using bolts or other methods, thereby enhancing the stability of the structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model uses a base fixed to the ground and a hinge to achieve the hinged installation of the vertical plate, supported by diagonal bracing plates, to form a stable foundation structure. The damper, buffer spring, aluminum foam buffer pad, and high-elastic rubber buffer pad on the front side of the vertical plate constitute a multi-stage buffer system, which can effectively absorb and disperse the energy generated by a vehicle impact, reducing the impact force on the vehicle and occupants. The top protective plate prevents the vehicle from overturning, further improving safety. The overall structural design is reasonable and can provide reliable protection in the event of a vehicle rollover or collision, reducing accident losses. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please refer to the accompanying drawings. This utility model provides a technical solution:
[0024] like Figures 1-3 As shown, the anti-overturning structure of the interchange ring road ramp divergence includes a base 1 fixed to the ground. A vertical plate 2 is hinged to the front top of the base 1 via a hinge shaft 6. A diagonal brace 3 for supporting the vertical plate 2 is fixed to the top of the base 1 via fixing bolts 30. A support plate 21 is provided on the front side of the vertical plate 2. A damper 20 is fixedly installed at each of the four corners of the front outer wall of the vertical plate 2. The support plate 21 is fixedly connected to the piston rods of the four dampers 20. Several buffer springs 25 are fixedly installed between the support plate 21 and the vertical plate 2. A foam aluminum buffer pad 22 is fixedly installed on the front outer wall of the support plate 21, and a high-elastic rubber buffer pad 23 is fixedly installed in front of the foam aluminum buffer pad 22. A top protective plate 4 is installed on the top of the vertical plate 2. The base 1 is fixed to the ground, the hinge shaft 6 enables the hinged installation of the vertical plate 2, and the diagonal brace 3 provides support, forming a stable foundation structure. The damper 20 and buffer spring 25 on the front side of the vertical plate 2, together with the aluminum foam buffer pad 22 and the high-elastic rubber buffer pad 23, constitute a multi-stage buffer system that can effectively absorb and disperse the energy generated by the vehicle impact, reducing the impact force on the vehicle and occupants. The top protective plate 4 can prevent the vehicle from overturning, further improving safety. The overall structural design is reasonable and can provide reliable protection when the vehicle rolls over or collides, reducing accident losses.
[0025] like Figure 2 As shown, in a preferred embodiment, the diagonal brace 3 is fixedly connected to the outer wall of the vertical plate 2 by fixing bolts 30. Several fixing bolts 30 are provided and are evenly spaced. Fixing the diagonal brace 3 to the vertical plate 2 with multiple evenly spaced fixing bolts 30 enhances the stability of the connection, ensuring that the diagonal brace 3 can effectively support the vertical plate 2, and improving the overall strength and impact resistance of the structure.
[0026] like Figure 1 As shown, in this preferred embodiment, the vertical plate 2 is installed vertically, and after disassembly, it can be rotated to a horizontal position. The vertical plate 2 can remain vertical during installation to provide protection, and can be rotated to a horizontal position after disassembly, facilitating transportation and storage, and improving the maintainability and practicality of the structure.
[0027] like Figure 1 As shown, in a preferred embodiment, the front side of the high-elastic rubber buffer pad 23 is provided with multiple waste tires 24. The waste tires 24 are fixedly connected to the support plate by multiple long screws, which pass through two buffer pads. This further increases the number of buffer pads, utilizes the elasticity and deformation capacity of the waste tires 24 to absorb more energy, and simultaneously realizes the reuse of waste resources, reducing costs.
[0028] like Figure 1 As shown, in a preferred embodiment, a top protective pad 40 is fixedly installed at the bottom of the top protective plate 4, and the top protective plate 4 is connected to the vertical plate 2 via a pin 5. The top protective pad 40 at the bottom of the top protective plate 4 enhances the protection of the vehicle, and the pin 5 connection method makes the installation and removal of the top protective plate 4 more convenient, facilitating maintenance and replacement.
[0029] like Figure 4 As shown, in this preferred embodiment, the insert shaft 5 is plugged into both the vertical plate 2 and the top protective plate 4. The cross-section of the insert shaft 5 is a regular N-gon, and N≥6. This design prevents the insert shaft 5 from rotating, ensuring the connection stability between the top protective plate 4 and the vertical plate 2, improving the reliability of the structure, and allowing adjustment of the angle of the top protective plate 4, increasing convenience during use.
[0030] like Figure 4 As shown, in a preferred embodiment, a limiting screw 50 is threaded onto one end of the insert shaft 5, and a screw head 51 is integrally formed coaxially on the outer wall of the limiting screw 50. The limiting screw 50 and the screw head 51 facilitate the limiting and fixing of the insert shaft 5.
[0031] like Figure 4 As shown, in a preferred embodiment, the base 1 has several equally spaced fixing holes 10 on both sides. The fixing holes 10 on both sides of the base 1 facilitate further fixing of the base 1 to the ground by means of bolts or other methods, thereby enhancing the stability of the structure.
[0032] In use, the anti-overturning structure of the interchange ring road ramp divergence of this utility model is first firmly fixed to the ground by bolts through the fixing holes 10 on both sides of the base 1. The diagonal brace 3 is firmly connected to the vertical plate 2 by multiple equally spaced fixing bolts 30 to form a stable support foundation. When the vehicle overturns or collides, the waste tire 24 and the high-elastic rubber buffer pad 23 first provide initial buffering and absorb some of the impact energy. Then, the foam aluminum buffer pad 22 further absorbs energy and disperses the impact force through its own plastic deformation. Finally, the support plate 21 absorbs the impact force. The action compresses the buffer spring 25 and drives the piston rod of the damper 20 to move. The buffer spring 25 stores energy through elastic deformation, while the damper 20 converts kinetic energy into heat energy. The multi-stage buffer structure works together to significantly reduce the impact force. At the same time, the top pad 40 at the bottom of the top protective plate 4, together with the vertical plate 2, effectively prevents the vehicle from overturning. The connecting component consisting of the insert shaft 5 and the limit screw 50 ensures that the top protective plate 4 is securely installed, while facilitating daily maintenance and angle adjustment. This provides comprehensive protection for the vehicle's safety at the ramp divergence and reduces accident losses.
