Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, and more specifically, relates to a guardrail component and a combined rotating traffic guardrail. Background Technology

[0002] Currently, guardrails are installed on the center line or side of the road. They are divided into fixed type and buried type. Fixed guardrails consist of concrete blocks installed on the center line or side of the road. The blocks are connected one by one and then fixed to the center line or side of the road with bolts to form a fixed guardrail. Regardless of whether it is fixed or buried, the main structure is too rigid, which leads to greater casualties among people inside the vehicle.

[0003] To address the aforementioned issues, a search revealed a Chinese invention patent (CN202116999U) that discloses a traffic barrier with an intermittently grounded rotating body. The barrier includes posts, an elastic rotating body fitted onto the posts, upper and lower horizontal bars respectively positioned above and below the elastic rotating body, and a rotating support piece fitted onto the posts and positioned between the lower horizontal bar and the elastic rotating body. The posts comprise alternating long and short posts; the long posts extend downwards to below the lower horizontal bar to form a mounting base, and the short posts... The two ends of the column are connected to the upper and lower horizontal bars respectively; Chinese invention patent (CN202849974U) discloses an SA-grade rotating anti-collision guardrail with an impact-absorbing rotating body, including a tubular column, a horizontal bar connected to the column, an elastic rotating body sleeved on the column, an upper horizontal bar and a lower horizontal bar respectively provided above and below the elastic rotating body, the upper horizontal bar includes at least an upper-level horizontal bar and a lower-level horizontal bar arranged in an arrangement, and a rotating support member sleeved on the column is provided between the lower end of the elastic rotating body and the lower horizontal bar.

[0004] However, when these patents are applied to road products, vehicles do not stop immediately after tilting and hitting the rotating barrel. After the front of the vehicle returns to the correct position, it still slides a distance close to the rotating guardrail. In addition, the rotating guardrails mentioned above are installed in dangerous traffic areas, such as the entrances and exits of highways. Due to the height difference in these road sections, the vehicles have a large potential energy. After the potential energy is converted into kinetic energy, the vehicles continue to slide forward, which is not conducive to the escape of drivers and passengers. Utility Model Content

[0005] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a guardrail component and a combined rotating traffic guardrail, which shortens the distance the vehicle slides close to the rotating guardrail after returning to its correct position.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] like Figures 1 to 2 As shown, the guardrail assembly of this embodiment includes a vertical post 1, a mounting shaft 2, and an elastic collision member 3. The mounting shaft 2 passes horizontally (along the horizontal direction) through the vertical post 1 and is fixedly connected to the vertical post 1. Both ends of the mounting shaft 2 extend to the outside of the vertical post 1. The elastic collision member 3 is sleeved on the mounting shaft 2 and is rotatably connected to the mounting shaft 2. The axis of the elastic collision member 3 coincides with the axis of the mounting shaft 2. The outer surface of the elastic collision member 3 has an arc-shaped structure. The elastic collision member 3 is made of EVA foam, which has good elasticity and wear resistance and can provide friction in the horizontal direction.

[0025] Combination Figure 1 As shown, there are two elastic collision elements 3. The two elastic collision elements 3 are evenly spaced along the length of the mounting shaft 2. A spacer sleeve 4 is provided between two adjacent elastic collision elements 3. The spacer sleeve 4 is fitted on the mounting shaft 2. The spacer sleeve 4 is made of hard plastic to avoid sticking to the elastic collision elements 3 and to ensure smooth rotation of the collision elements.

[0026] Furthermore, the vertical column 1 includes a base 5, which is welded and fixed to the vertical column 1. The vertical column 1 is vertically positioned above the base 5. The base 5 has four fixing holes, and anchor bolts 6 are inserted into the fixing holes. The base 5 is fixedly connected to the ground through the anchor bolts 6. During installation, the anchor bolts 6 are driven into the ground foundation through the fixing holes to fix the base 5.

[0027] In this embodiment, the two ends of the mounting shaft 2 are connected by a limit ring 7 through a thread. The diameter of the limit ring 7 is larger than the outer diameter of the mounting shaft 2 and larger than the inner diameter of the elastic collision member 3, which can effectively prevent the axial movement of the mounting shaft 2 and the detachment of the elastic collision member 3. When disassembling, simply unscrew the limit ring 7 to maintain or replace the elastic collision member 3 or the mounting shaft 2.

[0028] In this embodiment, the mounting shaft 2 is made of 45 seamless steel pipe, the vertical column 1 is made of Q235 round steel, and the base 5 is made of Q235 steel plate. The materials of each component are matched to ensure the overall strength of the guardrail.

[0029] Furthermore, the surface of the elastic collision component 3 is provided with an annular groove 8, and a reflective strip (not shown in the figure) is embedded in the groove 8. The reflective strip is made of a high-brightness reflective material, which can clearly reflect light when illuminated at night; or the surface of the elastic collision component 3 is coated with a reflective layer 9, the reflective layer 9 having a thickness of 0.1mm. The reflective layer 9 is formed by the curing of reflective paint, and the reflective effect is stable. The aforementioned reflective strips or reflective layers 9 reflect light at night, alerting passing vehicles and pedestrians, and improving safety.

[0030] In this embodiment, a column cap 10 is welded on the top of the vertical column 1. The column cap 10 is a hemispherical structure and is made of the same material as the vertical column 1. It can effectively block the opening at the top of the column and prevent impurities from entering.

[0031] During the installation of the guardrail assembly in this embodiment, the base 5 is first fixed to the ground at a preset position using anchor bolts 6. Then, the spacer sleeve 4 and the elastic collision member 3 are sequentially fitted onto the mounting shaft 2. The mounting shaft 2 is then inserted into the vertical column 1 and welded in place. Finally, limit retaining rings 7 are installed at both ends of the mounting shaft 2 to complete the assembly of the guardrail assembly.

[0032] like Figure 3 and Figure 4 As shown, this embodiment also provides a combined rotating traffic guardrail, including: a circular tube post 5; a rotating body 6 sleeved on the circular tube post 5; an upper horizontal bar 7 disposed above the rotating body 6 and a lower horizontal bar 8 disposed below it; and a rotating receiving member 9 sleeved on the circular tube post 5 and disposed between the lower horizontal bar 8 and the rotating body 6; and also includes the above-mentioned guardrail assembly, wherein the upper horizontal bar 7 and the lower horizontal bar 8 are respectively fixedly connected to the vertical post 1.

[0033] The rotating support 9 can adopt the following structure: 1) The rotating support 9 includes a base and a flange with a cover plate. The base and the flange are sequentially fitted onto the circular tube column 5 from bottom to top. An annular groove is opened at the center of the upper edge of the base. Rollers are provided at the center of the upper edge of the flange, corresponding to the annular groove. The elastic rotating body 6 is supported on the cover plate of the flange. 2) The rotating support 9 includes a base and a support plate with rollers. The base and the support plate are sequentially fitted onto the circular tube column 5 from bottom to top. The elastic rotating body 6 is placed on the support plate.

[0034] The base is a ring. The outer diameter of the ring is larger than the diameter of the cylindrical column 5 but smaller than the bottom diameter of the elastic rotating body 6. Symmetrical notches are opened on the ring. The notches cooperate with the head of the first screw. The ring is placed stably and is limited by the head of the first screw, so it will not rotate with the elastic rotating body 6, thus ensuring the normal rotation of the elastic rotating body 6.

[0035] The above examples are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design concept of the present invention shall fall within the protection scope of the present invention.
