Description

Technical Field

[0001] This utility model relates to the field of highway guardrail protection, and in particular to a guardrail composed of a small wave double crossbeam and a rotor. Background Technology

[0002] As an important protective facility for road traffic safety, highway guardrails have the core functions of intercepting out-of-control vehicles, guiding vehicle travel direction, and reducing collision damage. They also have auxiliary functions such as anti-glare and nighttime warning, playing an irreplaceable role in ensuring road traffic safety.

[0003] In existing highway guardrail technology, some lower crossbeams are too high or lack structural strength, allowing tires of low-chassis out-of-control vehicles to easily run under the guardrail, causing serious accidents such as vehicles running off the road or overturning. Furthermore, the uneven stiffness distribution of individual crossbeams results in poor adaptability to vehicles of different heights, failing to form a comprehensive protective barrier. Secondly, in existing highway guardrail technology, anti-glare panels are often welded to the guardrail crossbeams. Installation requires significant manpower and resources for positioning and tightening, and disassembly necessitates removing bolts or cutting weld points one by one. This cumbersome and time-consuming process severely impacts road construction efficiency.

[0004] It is evident that existing highway guardrail technologies suffer from incomplete protective coverage, poor adaptability to vehicles of different heights, low efficiency in the installation and maintenance of anti-glare panels, and negative impacts on road traffic and operating costs.

Detailed Implementation

[0021] The following detailed description of a small-wave double crossbeam and rotor combined guardrail of the present invention, in conjunction with the accompanying drawings and embodiments, will further illustrate this invention.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] according to Figures 1-11As shown, this small-wave double-beam and rotor combined guardrail includes: a post 1 fixed to the road surface by driving or pre-embedding; an upper crossbeam 2 and a lower crossbeam 3 for vehicle interception; a rotating cylinder 4 for buffering and guiding vehicle impact; and an anti-glare plate 5 for preventing glare at the median strip. To intercept vehicles of different heights, the upper crossbeam 2 is fixedly connected to the upper side of the post 1, and the lower crossbeam 3 is located below the upper crossbeam 2 and fixedly connected to the post 1. The upper crossbeam 2 intercepts the vehicle body, while the lower crossbeam 3 prevents the tires of out-of-control vehicles from passing under the guardrail and intercepts vehicles of lower height. To work together with the upper crossbeam 2 and lower crossbeam 3 to buffer and guide vehicle impact, a rotating cylinder 4 is installed between the upper crossbeam 2 and lower crossbeam 3, and the rotating cylinder 4 is rotatably connected to the post 1. To improve the installation efficiency of the anti-glare plate 5, the anti-glare plate 5 is detachably connected to the upper crossbeam 2, which facilitates installation and reduces installation time.

[0027] In this specific embodiment, the small-waveform external dimensions of the upper crossbeam 2 and the lower crossbeam 3 are defined as: length 4320mm × width 200mm × height 75mm. This differs from the ordinary two-waveform beams which are 4320mm long × width 310mm × height 85mm. The "small" here mainly refers to the 75mm height of the external waveform structure of the upper crossbeam 2 and the lower crossbeam 3, compared to the 85mm height of the external waveform structure of an ordinary waveform plate. To enable the anti-glare plate 5 to be detachably connected to the upper crossbeam 2, the anti-glare plate 5 is detachably connected to the upper crossbeam 2 via an anti-glare plate bracket 01. The anti-glare plate bracket 01 includes: a flat portion 011 for fixing the anti-glare plate 5, a fixing portion 012 for connecting, and a bending portion 013 and a snap-fit ​​component 014 for engaging the upper crossbeam. Specifically, the flat portion 011 has two integrally bent fixing portions 012 on both sides, and one side of the fixing portion 012 has an integrally bent bending portion 013. A snap-fit ​​member 014 is located near the flat portion 011, and is fixedly connected to the fixing portion 012. The snap-fit ​​member 014 abuts against the upper side of the upper crossbeam 2, and the bent portion 013 abuts against the lower side of the upper crossbeam 2. Together, they fasten the upper crossbeam 2, thus allowing the anti-glare panel bracket 01 to be fixed to the upper crossbeam 2 without bolts or other fasteners. Figure 4 As shown, the anti-glare panel bracket 01 is bolted to the upper side of the anti-glare panel 5, and both sides of the anti-glare panel bracket 01 are fastened to the upper crossbeam 2. This connection avoids reducing the structural strength by drilling holes in the upper crossbeam 2, making it easy to install and remove the anti-glare panel 5. During installation, one end of the upper crossbeam 2 is first fixedly connected to the column 1, and the anti-glare panel bracket 01 is fastened and inserted from the other end of the upper crossbeam 2. Multiple anti-glare panel brackets 01 can be fastened to one upper crossbeam 2 to install multiple anti-glare panels 5.

[0028] To ensure the column 1 can be securely connected to the upper crossbeam 2 and lower crossbeam 3, the side of the crossbeam 02 that contacts the column 1 is fixedly connected to the column 1 using bolts and nuts. Two crossbeams 02 are provided, corresponding to the upper crossbeam 2 and lower crossbeam 3 respectively. The crossbeam 02 closer to the anti-glare panel 5 is fixedly connected to the upper crossbeam 2 on both sides, while the crossbeam 02 farther from the anti-glare panel 5 is fixedly connected to the lower crossbeam 3 on both sides. Specifically, the upper side of the column 1 is defined as the side closer to the anti-glare panel 5, and the lower side of the column 1 is defined as the side buried in the ground. Two crossbeams 02 are provided on the column 1. The crossbeam 02 located on the upper side of the column 1 is fixedly connected to the upper crossbeam 2 on both sides, while the crossbeam 02 farther from the upper side of the column 1 is fixedly connected to the lower crossbeam 3 on both sides. The crossbeam 02 enhances the overall rigidity and stability between the two upper crossbeams 2 and the two lower crossbeams 3. Simultaneously, the crossbeam 02 also serves to secure the overlapping of multiple lower crossbeams 3 and upper crossbeams 2. In addition, the upper crossbeam 2 and lower crossbeam 3, combined with the crossbeams via corrugated plates, not only separate the two sides of the road but also serve as a collision buffer. This reduces the number of components, simplifies the structure, and improves production and installation efficiency. To ensure the ends of the guardrail, i.e., the starting and ending positions, have collision protection cylinders 6 installed on the posts 1 at the starting and ending positions of the guardrail. The collision protection cylinders 6 are fixedly connected to the crossbeams 02.

[0029] To ensure the crash barrier 6 is fixed to the end of the guardrail, it includes an outer cylinder 61 for protection and fixed brackets 62 on both sides of the crossbeam 02. The fixed brackets 62 are secured to both sides of the crossbeam 02 with bolts and nuts, thus fixing the upper crossbeam 2, lower crossbeam 3, fixed brackets 62, and crossbeam 02 together, reducing the number of connecting parts and ensuring structural strength. To provide crash protection, a buffer structure 63 is installed inside the outer cylinder 61. This honeycomb structure allows for excellent plastic deformation and energy absorption when the guardrail is impacted, preventing the upper or lower crossbeam 2 from penetrating the vehicle window. To make the posts 1 at the beginning and end highly visible, reflective grooves 611 are provided on the outside of the outer cylinder 61, with reflective film adhered inside.

[0030] To ensure that the anti-glare panel 5 can be fixed to the anti-glare panel bracket 01, the anti-glare panel 5 includes: a panel portion 51 that serves to prevent glare and a bent portion 52 that is fixed to the upper side of the anti-glare panel bracket 01 with bolts and nuts. The panel portion 51 is integrally bent to form the bent portion 52, which is fixedly connected to the flat portion 011. The bent portion 52 reduces the number of connecting parts between the panel portion 51 and the anti-glare panel bracket 01, improves structural strength, and facilitates installation.

[0031] To facilitate the separation of the bending portion 52 and the anti-glare panel bracket 01 upon impact, the bending portion 52 includes a first bending portion 521 and a second bending portion 522. The first bending portion 521 is integrally bent on one side of the panel portion 51, and the second bending portion 522 is integrally bent on the other side of the panel portion 51. The first bending portion 521 and the second bending portion 522 are arranged opposite to each other and are respectively fixedly connected to the flat portion 011. Release grooves 03 are respectively formed on the first bending portion 521 and the second bending portion 522, and the release grooves 03 are fixedly connected to the flat portion 011 by bolts. When the anti-glare panel 5 is impacted, the release grooves 03 on the first bending portion 521 and the second bending portion 522 are damaged and deformed, making it easy for the bolts to be released from the release grooves 03. When released from one side, the anti-glare panel 5 can also easily tilt to the other side. Two release slots 03 are located on both sides of the panel 51, so that when vehicles traveling in both directions on either side of the road collide, the curved part 52 can separate from the anti-glare bracket 01.

[0032] To make the rotating drum 4 highly visible and alert vehicles, it is made of elastic materials such as polyurethane foam or EVA, with a reflective film applied to the outer edge of the central groove. This serves multiple purposes, including visibility, collision energy dissipation, outline marking, and nighttime reflective guidance. To enhance the anti-slip performance of the rotating drum 4, anti-slip strips 41 are provided along its circumference, which better guide vehicles.

[0033] To prevent debris or rainwater from falling into the interior of the column 1, a cap 04 is fixedly connected to the end of the column 1 near the anti-glare plate 5. To prevent the cap 04 from falling off, a connector 041 is fixedly connected to the lower end of the cap 04. The connector 041 is connected and fixed to the column 1 and the crossbeam 02 by bolts and nuts.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
