Description

Technical Field

[0001] This utility model relates to the field of highway guardrail protection, and in particular to a highway guardrail with a combined structure of two-wave plates and a rotor. Background Technology

[0002] As road traffic protection facilities, highway guardrails primarily function to separate lanes, guide vehicle travel, and absorb collision energy and cushion impacts in the event of an accidental collision, preventing vehicles from running off the road or into oncoming lanes, thereby reducing the severity of accident damage. With the accelerated pace of highway construction and the increase in motor vehicle ownership, vehicle speeds and traffic density have significantly increased, placing higher demands on the comprehensive protective performance of highway guardrails. They not only need reliable anti-collision load-bearing capacity but also need to consider multiple functions such as anti-glare, visual guidance, and ease of maintenance.

[0003] Existing highway guardrail technologies suffer from several drawbacks. First, the installation of anti-glare panels is complex, requiring disassembly of the entire structure for individual component replacements, resulting in low maintenance efficiency. Second, anti-collision structures are often rigid or flexible designs. Rigid guardrails concentrate impact force upon collision, easily causing secondary injuries to vehicles and occupants. Flexible guardrails, on the other hand, suffer from insufficient protective stability and are prone to excessive deformation, making it difficult to balance protective strength and cushioning effect. Third, existing corrugated plate guardrails absorb energy solely through their own deformation, making them susceptible to rebound, rollover, or jamming upon vehicle impact. They lack effective rotating guide structures to help disperse impact force. Furthermore, the reliability of component connections is insufficient, and long-term exposure to vehicle scrapes, wind, and other factors can lead to loosening, affecting the overall protective performance of the guardrail.

[0004] It is evident that existing highway guardrail technologies suffer from problems such as complex installation methods, low maintenance efficiency, and a lack of effective rotating guide structures to help disperse impact forces. Utility Model Content

Detailed Implementation

[0021] The following description, in conjunction with the accompanying drawings and embodiments of the present invention, provides a more detailed account of a highway guardrail with a two-wave plate and rotor combination structure.

[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 counterparts 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.

[0026] according to Figures 1-12 As shown, this highway guardrail with a two-wave plate and rotor combination structure includes: an anti-glare plate 1 for glare reduction; a main crossbeam 2 as the core component for load-bearing and connecting the posts 3 and the anti-glare plate 1; the bottom end of the posts 3 is embedded in the road surface for fixation; and a rotating cylinder 5 and wave plates 4 as buffer components for collision prevention. The anti-glare plate 1 is fixedly connected to the upper side of the main crossbeam 2, which can reduce glare interference caused by oncoming vehicle lights, ensuring clear vision and driving safety for the driver. The main crossbeam 2 is also fixedly connected to the posts 3, enhancing the overall stability of the guardrail. Multiple main crossbeams in the same direction are connected together. Two wave plates 4 are fixedly connected to both sides of the posts 3, and multiple wave plates 4 in the same direction are overlapped and fixed together. A rotating cylinder 5 is installed between the main crossbeam 2 and the wave plates 4. The rotating cylinder 5 is rotatably connected to the posts 3. The rotating cylinder 5 is elastic and plays a role in assisting energy dissipation and guidance in the event of a collision, further reducing accident damage. The combination of corrugated plate 4 and rotating cylinder 5 can further improve the impact resistance of the guardrail. When a vehicle collision occurs, corrugated plate 4 absorbs energy through its own deformation, reduces the impact force, and prevents the guardrail from deforming and collapsing. Rotating cylinder 5 guides the vehicle to slide smoothly by rotating, reducing friction and rebound. The two work together to reduce impact force and vehicle damage, and the structure is compact and stable.

[0027] The lower end of the anti-glare panel is fixedly connected to the main crossbeam via the anti-glare panel bracket 01, and the lower end of the anti-glare panel 1 is fixedly connected to the main crossbeam 2 via the anti-glare panel bracket 01. This one-end fixed method ensures structural strength while also guaranteeing the anti-glare function. Furthermore, the anti-glare panel 1 is located on the upper side of the column 3 and the main crossbeam 2, making it less susceptible to damage during vehicle collisions.

[0028] To securely connect the main crossbeam 2 to the column 3, a crossbeam bracket 02 is used to connect them. The crossbeam bracket 02 is located on the upper side of the column 3 and includes a curved portion 021 that conforms to the shape of the outer wall of the column 3 and a fixing portion 022 that is fixedly connected to the main crossbeam 2. The fixing portion 022 is integrally bent on both sides of the curved portion 021. Preferably, the curved portion 021 has bolt holes for fixing to the column 3 using bolts and nuts. Similarly, the fixing portion 022 also has bolt holes and is fixed to the main crossbeam 2 using bolts and nuts. The curved portion 021 and the fixing portion 022 fix the column 3 between the two main crossbeams 2, allowing the crossbeam bracket 02 and the anti-glare panel bracket 01 to act as reinforcing ribs between the main crossbeams 2. Furthermore, in conjunction with the anti-glare panel bracket 01, they further enhance the anti-collision effect of the main crossbeam 2.

[0029] To ensure that the two corrugated plates 4 can be fixed to both sides of the column 3, a crossbeam 03 is fixedly connected to the column 3. The crossbeam 03 connects the corrugated plates 4 to both sides of the column 3, serving as a collision buffer for the lanes on both sides. The crossbeam 03 includes: a fitting part 031 that is tangential to and fixed to the outer side of the column 3, and a connecting part 032 that serves to fix the corrugated plates 4. Preferably, the fitting part 031 has an opening and is fixedly connected to the column 3 with bolts and nuts. The connecting part 032 has an opening and is fixedly connected to the corrugated plates 4 with bolts and nuts. In this specific embodiment, the main crossbeam 2 is a rectangular tube, and the two main crossbeams 2 are respectively bolted to both sides of the column 3 through fixing parts 022. The two corrugated plates 4 are respectively bolted to both sides of the column 3 through connecting parts 032.

[0030] To facilitate installation and reduce installation time, the posts 3 include: anchor posts 31 with their bottoms fixed to the road surface, and ground-mounted posts 32 longitudinally positioned between two spaced anchor posts 31. The ground-mounted posts 32 are shorter than the anchor posts 31 and their bottoms are not fixed to the road surface. The upper sides of the anchor posts 31 and the ground-mounted posts 32 are fixedly connected to the crossbeam brackets 02, and their lower sides are fixedly connected to the crossbeams 03. The bottom of the ground-mounted posts 32 does not contact the road surface. A first rope 04 is installed between the anchor posts 31 and the ground-mounted posts 32, and correspondingly, a first rope 04 is installed between the ground-mounted posts 32 and the anchor posts 31. This guardrail design reduces the number of posts 3 fixed to the ground while ensuring structural strength, saving costs and improving installation efficiency. Combined with the subsequent connection of the first rope 04 and the second rope 05, the guardrail as a whole possesses both rigid load-bearing capacity and flexible buffering capacity.

[0031] To ensure that the highway guardrail has a rigid-flexible anti-collision structure, specifically, a first connecting hole 311 is provided on the anchor post 31, and a seventh connecting hole 321 is provided on the post 32 off the ground. The first connecting hole 311 and the seventh connecting hole 321 are respectively fixedly connected to the bending part 021.

[0032] Anchor post 31 has a second connecting hole 312 and a third connecting hole 313, while the off-ground post 32 has an eighth connecting hole 322 and a ninth connecting hole 323. The second connecting hole 312 and the eighth connecting hole 322 are connected by a first rope 04. This allows the anchor post 31 and the off-ground post 32 to be connected. Of course, to allow the off-ground post 32 to connect to the next anchor post 31, the first rope 04 can also pass through the third connecting hole 313 and the ninth connecting hole 323. Multiple connecting holes are provided for flexible combination and connection of the first rope 04 and the second rope 05. Anchor post 31 has a fourth connecting hole 314, and the off-ground post 32 has a tenth connecting hole 324. The fourth connecting hole 314 and the tenth connecting hole 324 are respectively fixedly connected to the fitting part 031.

[0033] To ensure the connection strength between the two anchor posts 31 and the ground-mounted post 32, a fifth connecting hole 315 and a sixth connecting hole 316 are provided on the anchor post 31, and an eleventh connecting hole 325 is provided on the ground-mounted post 32. A second rope 05 is provided between the two anchor posts 31. The two anchor posts 31 are connected by the fifth connecting hole 315 and the second rope 05 respectively, or the two anchor posts 31 are connected by the sixth connecting hole 316 and the second rope 05 respectively. The second rope 05 is provided by passing through the eleventh connecting hole 325. The first rope 04 and the second rope 05 are respectively fixedly connected to the column 3 by the pretensioner 6, and the two ends of the first rope 04 and the two ends of the second rope 05 are respectively fixedly connected to the pretensioner 6.

[0034] The first rope 04 and the second rope 05 provide a flexible connection at the bottom of the ground-mounted column 32, while the fourth connecting hole 314 of the anchor column 31 and the tenth connecting hole 324 of the ground-mounted column 32 ensure that they can be fixed to the crossbeam 03 respectively. The first rope 04 passing through the second connecting hole 312 and the eighth connecting hole 322, or the third connecting hole 313 and the ninth connecting hole 323, also assists in fixing the crossbeam 03. This creates a rigid-flexible combination structure between the ground-mounted column 32 and the anchor column 31, which deforms along with the corrugated plate 4 during impact, thus buffering and dissipating energy. The first rope 04 and the second rope 05 can transmit tension, allowing the ground-mounted column 32 and the anchor column 31 to share the force collaboratively. During a collision, the tension deformation of the first rope 04 and the second rope 05 helps absorb energy and avoids localized force concentration. Meanwhile, this connection method allows the guardrail to remain intact when subjected to impact, thanks to the anchor post 31, while also providing elastic buffering through the cooperation of the ground-mounted post 32 with the first rope 04 and the second rope 05, effectively guiding the vehicle and reducing the impact force of the collision.

[0035] To keep the first rope 04 and the second rope 05 taut, a pretensioner 6 is fixedly connected to the ends of both ropes. The pretensioner 6 includes a pretensioner head 61 for fixing and a pretensioner nut 62 for adjusting tension. The pretensioner head 61 includes a crimping portion 611 and a threaded portion 612. A crimping hole 6111 is provided on the crimping portion 611, and the ends of the first rope 04 and the second rope 05 are respectively crimped into the crimping hole 6111 and the crimping portion 611 for fixing. A thread is provided on the threaded portion 612, and the threaded portion 612 is threadedly connected to the pretensioner head 61. This allows the tension to be adjusted from the ends of the first rope 04 and the second rope 05 by rotating the pretensioner nut 62, giving the taut first rope 04 and the second rope 05 a stronger elastic deformation capacity.

[0036] The pre-tensioning component 6 also includes a tightening component 63, which is detachably connected to the pre-tensioning nut 62 to prevent rainwater intrusion. The tightening component 63 has a tightening groove 631, through which the pre-tensioning nut 62 can be tightened. The pre-tensioning bolt head 61 extends out of the connection hole of the anchor post 31 or the off-ground post 32, and is then fixed by rotating the pre-tensioning nut 62, thereby securing the ends of the first rope 04 and the second rope 05 to the post 3.

[0037] To enable the preload nut 62 to be threadedly connected to the preload bolt head 61, the preload nut 62 includes a circular portion 621 for fixing and a protrusion 622 for facilitating rotation of the preload nut 62. To ensure structural strength, the protrusion 622 protrudes outward from the circular portion 621, and the protrusion 622 and the circular portion 621 are integrally formed. Multiple protrusions 622 are arranged circumferentially around the circular portion 621. A bolt hole 6211 is provided in the circular portion 621, and the bolt hole 6211 is threadedly connected to the threaded portion 612. The tightening groove 631 has the same dimensions as the protrusion 622, and the positions of multiple tightening grooves 631 and multiple protrusions 622 correspond to each other. The tightening grooves 631 and protrusions 622 are detachably connected. The protrusion 622 is inserted into the tightening groove 631, thereby rotating the tightening member 63 to fix the preload nut 62 onto the threaded portion 612.

[0038] To enable the rotating drum 5 to absorb and reduce force through rotation, a connecting hole 51 is provided in the middle of the drum 5, through which the column 3 passes and is rotatably connected to the drum 5. Simultaneously, to make the drum 5 more visible, a groove 52 is formed around its circumference on the side of the drum 5. Reflective film is adhered inside the groove 52. The brightly colored drum 5 enhances road contour guidance and improves the driver's anticipation of road direction. To avoid blind spots, multiple anti-glare panels 1 are longitudinally arranged along the main crossbeam 2, and the panels are equidistantly distributed. The drum 5 is made of an elastic material, such as polyurethane foam or EVA, and is elastic. This reduces the direct impact force on the vehicle and guardrail, further dispersing the force and guiding the vehicle to glide smoothly.

[0039] 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.
