Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically relating to a high-speed anti-collision and noise-reducing guardrail. Background Technology

[0002] Guardrails are mainly used in residential areas, highways, commercial areas, public places and other places to protect personal safety and equipment facilities. The existing highways have rotating guardrails installed on both sides, which are guardrails with multiple rotating barrels arranged side by side in the middle of the crossbeam for better protection.

[0003] When a rotating guardrail is struck from the side by a high-speed vehicle, its rotating barrels convert the impact force into rotational kinetic energy, absorbing the impact force. The vehicle is guided to slide along the rotating guardrail, preventing it from crashing through. However, existing rotating guardrails have limited noise reduction effects and cannot meet the environmental protection requirements of modern highways. Therefore, an improved high-speed collision-resistant and noise-reducing guardrail has been designed. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a high-speed anti-collision and noise reduction guardrail to solve the problems in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-speed anti-collision and noise reduction guardrail includes multiple column assemblies evenly spaced on a base plate. Rotational protection components are installed on the column assemblies, and noise reduction plates are connected between adjacent column assemblies. The noise reduction plates are three-layer structures consisting of an aluminum alloy perforated plate, a glass wool felt layer, and a butyl rubber damping sheet bonded together sequentially from the outside to the inside.

[0007] Furthermore, the column assembly includes a base embedded in and connected to the base plate, a column fixedly connected to the base, and a rearwardly inclined upper support section at the top of the column, the upper support section having an installation through hole for installing a guardrail.

[0008] Furthermore, the column assembly also includes two sets of parallel connecting components, each set of connecting components including two connectors, which are connected to the column via L-shaped connecting rods.

[0009] Furthermore, the rotating protective assembly includes two mounting brackets arranged side by side, which are connected to the column via a connecting assembly. It also includes a rotating barrel and a connecting shaft, which are connected between the two mounting brackets. The rotating barrel is fitted around the outer periphery of the connecting shaft.

[0010] Furthermore, the mounting bracket includes two mounting rods and mounting bases connected to the two mounting rods, with the connecting shaft rotatably connected between the upper and lower bases.

[0011] Furthermore, the connector includes two coaxially connected fixed disks, and the noise reduction plate is connected between the two fixed disks.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. The rotating barrel in the rotating guardrail assembly forms a rotatable structure by connecting the rotating shaft and the mounting bracket. When a vehicle impacts the guardrail from the side, the rotating barrel is driven by the impact force to rotate the connecting shaft, converting the collision kinetic energy into rotational mechanical energy. At the same time, the rotation guides the vehicle to slide along the guardrail, preventing the vehicle from directly running off the road or violently overturning, thus reducing the risk of personal injury and vehicle damage.

[0014] 2. The rearward-sloping upper support section at the top of the column forms a trapezoidal impact-resistant structure with the guardrail, which, together with the embedded connection between the base and the substrate, enhances the overall anti-tipping capability of the guardrail. The upper and lower sets of connecting components, L-shaped connecting rods and connectors, clamp the noise reduction plate with a fixing disc, forming a composite structure of "rigid support + flexible connection", dispersing the impact force to adjacent column units and avoiding structural failure caused by single-point stress;

[0015] 3. The noise reduction board is flexibly installed through the fixed disc of the connector, forming an elastic floating gap with the column assembly, cutting off the solid sound transmission path and achieving the noise reduction effect. Attached Figure Description

[0028] like Figure 1-5As shown, this utility model provides a high-speed anti-collision and noise-reducing guardrail, comprising multiple column assemblies 200 evenly spaced on a base plate 100, a rotating protective assembly 400 mounted on each column assembly 200, and noise-reducing plates 500 connected between adjacent column assemblies 200. The noise-reducing plate 500 is a three-layer structure consisting of an aluminum alloy perforated plate 501, a glass wool felt layer 502, and a butyl rubber damping sheet 503 bonded sequentially from the outside to the inside.

[0029] The column assembly 200 includes a base 201 embedded in and connected to the base plate 100, and a column 22 fixedly connected to the base 201. The top of the column 22 is provided with a rearwardly inclined upper support section 203, and the upper support section 203 is provided with a mounting through hole for installing the guardrail 300.

[0030] The column assembly 200 also includes two sets of parallel connecting components, each set of connecting components including two connectors 205, which are connected to the column 22 by an L-shaped connecting rod 204.

[0031] The rotating protective assembly 400 includes two mounting brackets 401 arranged side by side, which are connected to the column 22 by a connecting assembly. It also includes a rotating barrel 402 and a connecting shaft 403, which are connected between the two mounting brackets 401. The rotating barrel 402 is fitted around the outer periphery of the connecting shaft 403.

[0032] Mounting bracket 401 includes two mounting rods 4011 and mounting bases 4012 connected to the two mounting rods 4011. A connecting shaft 403 is rotatably connected between the upper and lower bases 4012.

[0033] The connector 205 includes two coaxially connected fixed disks, and the noise reduction plate 500 is connected between the two fixed disks.

[0034] The noise reduction panel adopts a three-layer composite sound absorption and insulation structure, from the outside to the inside: Outer impact-resistant protective layer: A 2-3mm thick perforated aluminum alloy plate with 3-5mm diameter holes arranged in a quincunx pattern. The surface is anodized, providing both corrosion and impact resistance while also providing an incident channel for sound waves. Middle sound-absorbing layer: Filled with 50-80mm thick centrifugal glass wool felt, its porous structure forming numerous micropores, creating viscous resistance when sound waves enter and rub against the fibers. Inner sound insulation and damping layer: A 1-2mm thick butyl rubber damping sheet, using the damping properties of the polymer material to suppress panel vibration and reduce solid-borne sound transmission. The rotating barrel 402 in the rotating protective assembly 400 forms a rotatable structure by connecting the rotating shaft 403 to the mounting bracket 401. When a vehicle strikes the guardrail from the side, the rotating barrel is driven by the impact force to rotate the connecting shaft, converting the collision kinetic energy into rotational mechanical energy. At the same time, the rotation guides the vehicle to slide along the guardrail, preventing the vehicle from directly running off the road or violently overturning, thus reducing the risk of personal injury and vehicle damage.
