Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to an anti-collision device for road transportation engineering. Background Technology

[0002] In road transportation engineering, crash barriers are key facilities to ensure road traffic safety. They are widely used on both sides or in the central divider of highways, urban roads and expressways. Their main function is to prevent out-of-control vehicles from deviating from their lanes and to prevent accidents from escalating.

[0003] Currently, most road crash barriers on the market adopt a rigid structure design, such as concrete barriers and metal barriers. Because these barriers lack an effective buffer structure, they cannot buffer and absorb the impact generated during a collision. This characteristic not only easily leads to serious damage to vehicles, but also greatly increases the risk of injury to people inside the vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a collision avoidance device for road transportation engineering, which has the advantages of effective collision buffer and energy absorption structure, reducing the impact on the occupants of the vehicle during a collision and reducing the risk of injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance device for road transportation engineering, comprising two columns and two crossbars. Each column has an aluminum alloy energy-absorbing box fixedly installed on both sides. An arc-shaped baffle is fixedly installed on the surface of the aluminum alloy energy-absorbing box, away from the column. A second hollow rubber strip is fixedly connected to the surface of the arc-shaped baffle, away from the aluminum alloy energy-absorbing box. Mounting seats are fixedly installed at both ends of the two columns on their closest sides. The crossbars also have two mounting seats fixedly installed on both sides. A fixed plate is provided, and hollow rubber columns are fixedly installed between the two sides of the fixed plate and the two sides of the inner cavity of the mounting base. The inner cavity of the hollow rubber columns is filled with a second buffer spring. The surface of the crossbar is provided with a through hole, and a first buffer spring is fixedly installed on both sides of the through hole. An aluminum alloy energy-absorbing frame is fixedly installed on the surface of the first buffer spring and on the side away from the through hole. A crash barrier is fixedly installed between the surfaces of the two aluminum alloy energy-absorbing frames and on the side away from the first buffer spring. A first hollow rubber strip is fixedly connected to the surface of the crash barrier and on the side away from the aluminum alloy energy-absorbing frame.

[0006] As a preferred embodiment, a top cover is fixedly installed on the top of the column, and reflectors are fixedly installed on both sides of the top cover.

[0007] As a preferred embodiment, the bottom of the column is fixedly connected to a mounting base plate, and mounting holes are provided on all four sides of the mounting base plate.

[0008] As a preferred embodiment, limit rods are fixedly installed between the two ends of the two anti-collision guardrails on the side closest to each other, and the surface of the limit rods is slidably connected to the surface of the through hole.

[0009] As a preferred embodiment, a guide rod is fixedly installed in the inner cavity of the mounting base, and the surface of the fixing plate is slidably connected to the middle end of the guide rod.

[0010] As a preferred embodiment, the fixing plate is T-shaped, and reinforcing ribs are provided on both sides of the fixing plate.

[0011] As a preferred embodiment, two uprights are fixedly installed between the two crossbars on their adjacent sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the installation of an arc-shaped baffle and a second hollow rubber strip, can form a collision protection on the side of the column. Simultaneously, under the action of the aluminum alloy energy-absorbing box, it can support the arc-shaped baffle and the column. When the arc-shaped baffle is subjected to a large-force impact, it can compress and collapse the aluminum alloy energy-absorbing box, thereby absorbing the impact energy and reducing the impact on the occupants. Furthermore, through the installation of the crash barrier and the first hollow rubber strip, it can form a collision protection on the side of the crossbar. Under the action of the aluminum alloy energy-absorbing frame and the first buffer spring, it can connect the crossbar and the crash barrier. Simultaneously, when the crash barrier is impacted, it can push the aluminum alloy energy-absorbing frame to compress the first buffer spring and generate a certain thrust on the crossbar. This causes the crossbar to drive the fixing plate to compress the hollow rubber column and the second buffer spring in the mounting base. This buffers the impact force during the collision. When the collision force is large, it causes the aluminum alloy energy-absorbing frame to contact the side of the crossbar and collapse under the squeezing action of the crash barrier. This absorbs the energy of the impact during the collision, greatly reducing the impact of the collision on the occupants and improving their safety during the collision. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] The components in this application, such as column 1, mounting base 2, fixing plate 3, crossbar 4, upright 5, anti-collision guardrail 6, first hollow rubber strip 7, mounting base plate 8, arc-shaped baffle 9, second hollow rubber strip 10, guide rod 11, hollow rubber column 12, reinforcing rib 13, through hole 14, first buffer spring 15, aluminum alloy energy-absorbing frame 16, limiting rod 17, top cover 18, reflector 19, aluminum alloy energy-absorbing box 20, and second buffer spring 21, are all general standard parts or components known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1:

[0023] Please see Figures 1-4As shown, this utility model provides a collision avoidance device for road traffic engineering, including two columns 1 and two crossbars 4. Two aluminum alloy energy-absorbing boxes 20 are fixedly installed on both sides of each column 1. An arc-shaped baffle 9 is fixedly installed on the surface of the aluminum alloy energy-absorbing box 20 away from the column 1. A second hollow rubber strip 10 is fixedly connected to the surface of the arc-shaped baffle 9 away from the aluminum alloy energy-absorbing box 20. Mounting seats 2 are fixedly installed at both ends of the two columns 1 on the side closest to each other. Two crossbars 4 are provided, and fixing plates 3 are fixedly installed on both sides of each crossbar 4. Hollow rubber columns 12 are fixedly installed between the two sides of the inner cavity of the mounting base 2. The inner cavity of the hollow rubber columns 12 is filled with a second buffer spring 21. The surface of the crossbar 4 is provided with a through hole 14. A first buffer spring 15 is fixedly installed on both sides of the through hole 14. An aluminum alloy energy-absorbing frame 16 is fixedly installed on the surface of the first buffer spring 15 away from the through hole 14. A crash barrier 6 is fixedly installed between the surfaces of the two aluminum alloy energy-absorbing frames 16 away from the first buffer spring 15. A first hollow rubber strip 7 is fixedly connected to the surface of the crash barrier 6 away from the aluminum alloy energy-absorbing frame 16.

[0024] In this technical solution, the arc-shaped baffle 9 and the second hollow rubber strip 10 form a collision protection barrier on the side of the column 1. Under the action of the aluminum alloy energy-absorbing box 20, the arc-shaped baffle 9 and the column 1 are supported. When the arc-shaped baffle 9 is subjected to a large-force collision, it can compress and collapse the aluminum alloy energy-absorbing box 20, thus absorbing energy and reducing the impact on the occupants. Simultaneously, the crash barrier 6 and the first hollow rubber strip 7 form a collision protection barrier on the side of the crossbar 4. Under the action of the aluminum alloy energy-absorbing frame 16 and the first buffer spring 15, the energy absorption barrier between the crossbar 4 and the crash barrier 6 is also supported. While the guardrail is in operation, when the guardrail 6 is impacted, it can push the aluminum alloy energy-absorbing frame 16 to compress the first buffer spring 15 and generate a certain thrust on the crossbar 4. This causes the crossbar 4 to drive the fixing plate 3 to compress the hollow rubber column 12 and the second buffer spring 21 in the mounting base 2. This can buffer the impact force during the collision. When the collision force is large, it can cause the aluminum alloy energy-absorbing frame 16 to contact the side of the crossbar 4. Under the squeezing action of the guardrail 6, the aluminum alloy energy-absorbing frame 16 can collapse, thus absorbing the impact during the collision. This greatly reduces the impact of the collision on the occupants and improves the safety of the occupants during the collision.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a top cover 18 is fixedly installed on the top of the column 1, and reflectors 19 are fixedly installed on both sides of the top cover 18. A mounting base plate 8 is fixedly connected to the bottom of the column 1. Mounting holes are provided around the mounting base plate 8. Limiting rods 17 are fixedly installed between the two ends of the two anti-collision guardrails 6 on the side closest to each other. The surface of the limiting rod 17 is slidably connected to the surface of the through hole 14. A guide rod 11 is fixedly installed in the inner cavity of the mounting base 2. The surface of the fixing plate 3 is slidably connected to the middle end of the guide rod 11. The fixing plate 3 is T-shaped. Reinforcing ribs 13 are provided on both sides of the fixing plate 3. Two uprights 5 are fixedly installed between the two ends of the two crossbars 4 on the side closest to each other.

[0027] In this technical solution, the reflector 19 effectively enhances the warning effect of the device during nighttime use. The mounting base plate 8 and mounting holes facilitate the installation and fixation of the column 1. The limiting rod 17 connects the two crash barriers 6 on both sides and limits and guides the crash barriers 6 and the crossbar 4 to prevent the crash barriers 6 from shifting. The guide rod 11 limits and guides the fixing plate 3 inside the mounting base 2 to prevent the fixing plate 3 from shifting. The reinforcing rib 13 strengthens both sides of the fixing plate 3. The upright 5 provides support and fixation between the two crossbars 4.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
