Description

Technical Field

[0001] This invention relates to the field of guardrail technology, specifically to an ultra-weather-resistant highway guardrail. Background Technology

[0002] Highway guardrails are a primary form of semi-rigid guardrails. They are continuous structures made of corrugated steel guardrail panels spliced ​​together and supported by posts. They absorb energy during vehicle collisions, making them less prone to damage and providing excellent protection for vehicles and occupants. The bending of the guardrails enhances their aesthetics while also increasing their strength. Due to their long service life, highway guardrails are susceptible to the effects of wind, rain, and sun exposure; therefore, they possess a certain degree of weather resistance.

[0003] In the prior art, such as the Chinese patent CN111500164A entitled "A High Weather-Resistant and Stain-Resistant Metal Fence Coating and Its Preparation Method", it includes the following components in parts by weight: 20-30 parts of polyester resin, 20-30 parts of hydroxyl acrylic resin, 10-15 parts of fluorinated hydrophobic material, 1-5 parts of crosslinking agent, 1-3 parts of boric acid, 1-3 parts of shell powder, 3-5 parts of stainless steel powder, 1-3 parts of ultrafine wax powder, 1-3 parts of functional filler, 0.1-0.5 parts of nano stain-resistant agent, 0.1-0.5 parts of nano anti-aging agent, and 0.1-0.5 parts of nano heat-insulating agent.

[0004] However, in existing technologies, when a guardrail is hit by a vehicle, although the impact point is concentrated in one place, if the load-bearing force at that point is large, and the existing guardrail only uses posts to set up buffer points, when one guardrail is hit, a large area of ​​the guardrail will deform due to the impact. Adding posts to connect can expand the protection range of the guardrail, but the construction cost is high. Therefore, the buffer protection range of the existing guardrail is relatively dispersed, and the area of ​​deformation and damage after impact is large, which leads to high subsequent maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide an ultra-weather-resistant highway guardrail to solve the problem mentioned in the background art: existing guardrails only use posts to set up buffer points, and when one guardrail is hit, a large area of ​​the guardrail will be deformed by impact. Adding posts to connect can expand the protection range of the guardrail, but the construction cost is high. Therefore, the buffer protection range of existing guardrails is relatively dispersed, and the area of ​​deformation and damage after impact is large, which leads to high subsequent maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-weather-resistant highway guardrail, comprising guardrail panels, posts, and a connecting mechanism. Positioning holes are provided at both ends of the guardrail panels. The guardrail panels are connected to the posts via the connecting mechanism. Supporting mechanisms are provided on both sides of the connecting mechanism. The guardrail is composed of multiple sets of guardrail panels and multiple sets of posts. Two adjacent guardrail panels are connected to the posts via positioning holes at their outer ends. Each post is also provided with supporting mechanisms on both outer sides. The supporting mechanisms and the guardrail panels respectively form a triangular support structure, thereby strengthening the stability of the connection between the posts and the guardrail panels.

[0007] The connecting mechanism includes a pipe clamp, a mounting plate is provided on one side of the pipe clamp, the column is connected to the side wall of the mounting plate through the pipe clamp, a first protective plate is provided on one side of the guardrail, a protective component is provided on the other side of the guardrail, a threaded post is connected to the side wall of the mounting plate, and one end of the threaded post passes through the positioning hole and is fixedly connected to the first protective plate.

[0008] The support mechanism includes a support frame, a first rotating seat is fixedly connected to the side wall of the support frame, pads are fixedly connected to both ends of the side wall of the mounting plate, a rotating assembly is provided on the side wall of the pad, and a rotating rod is rotatably connected between the first rotating seat and the rotating assembly.

[0009] Preferably, the bottom end of the column is fixedly connected to a base, and the outer side wall of the column is provided with annular patterns.

[0010] Preferably, the top and bottom ends of the support frame are provided with positioning plates, which are made of aluminum alloy.

[0011] Preferably, the pipe clamp has a first mounting hole at both ends of its sidewall, and the mounting plate has a second mounting hole at both ends.

[0012] Preferably, a screw is slidably connected to the side wall of the pad, and one end of the screw passes through the second mounting hole and the first mounting hole and is threadedly connected to a second nut.

[0013] Preferably, the rotating assembly includes a second rotating seat and a rotating column, with both ends of the rotating column passing through both sides of the second rotating seat and fixedly connected with anti-slip stripes.

[0014] Preferably, a sealing ring is movably connected to the outer wall of the rotating column, a connecting column is fixedly connected between the sealing ring and the screw, and the rotating rod is fixedly connected to the rotating column.

[0015] Preferably, the protective component includes a side support plate and a second protective plate, and a first nut is provided between the side support plate and the second protective plate.

[0016] Preferably, the side wall of the second protective plate is fixedly connected to two baffles, the first nut is threadedly connected to the threaded post, and a spring is fixedly connected between the side support plate and the mounting plate.

[0017] Preferably, the guardrail panel comprises a panel body and the following raw materials in parts by weight: 1000-1200 parts by weight of polyester resin, 70-110 parts by weight of titanium dioxide, 100-170 parts by weight of barium sulfate powder, 4-5 parts by weight of bentonite, 4-6 parts by weight of anti-flash rust additive, 3.5-4 parts by weight of wax powder, 0.7-1 parts by weight of sanding agent, 5-6 parts by weight of leveling agent, 2-4 parts by weight of benzoin, 0.4-1 parts by weight of defoamer, 0.1-3 parts by weight of carbon black, and 1.5-2 parts by weight of iron oxide yellow. The polyester resin is mixed with the other ingredients in the specified proportions and then subjected to uniform mixing. The mixture is then extruded, cooled, crushed, ground, and sieved to obtain the desired powder. The powder coating is then uniformly sprayed onto the outer surface of the panel body using an electrostatic spraying machine. After curing at 200 °C for 15 min, the panel is removed, cooled, and a weather-resistant guardrail panel is obtained.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, a connecting mechanism is set at the connection point of two adjacent guardrail panels. The first protective plate is attached to the outside of the guardrail panel 1. The protective component is pushed towards the first protective plate, so that the first protective plate and the protective component are clamped on both sides to fix the guardrail panel. The support frame is snapped onto the outside of the guardrail panel. The support frame and the pad are laterally supported by a rotating rod, which increases the support range of the column on the guardrail panel, reduces the deformation area of ​​the guardrail panel after impact, and thus reduces the maintenance cost of the guardrail panel after an accident.

[0020] 2. In this invention, by setting easily deformable and bendable locking plates at the top and bottom of the support frame, when the support frame is installed and connected to the guardrail, the two locking plates are bent inward so that the bent parts of the locking plates are locked and fixed to the guardrail, so that the rotating rod no longer rotates arbitrarily, thereby enhancing the stability of the rotating rod and improving the support effect of the support mechanism on the guardrail.

[0021] 3. In this invention, the support position of the support frame and the guardrail is adjusted by adjusting the installation angle of the rotating rod. Then, the pad and the mounting plate are connected by screws. While the screws are being installed, the connecting column will also move to one side, so that the sealing ring tightens the rotating column and fixes it to the second rotating seat, thereby adjusting the support range of the guardrail and enabling the support mechanism to support and position guardrails of different lengths.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0031] according to Figure 1-7 As shown: A super weather-resistant highway guardrail includes a guardrail panel 1, a post 2 and a connecting mechanism 3. Positioning holes 11 are provided at both ends of the guardrail panel 1. The guardrail panel 1 is connected to the post 2 through the connecting mechanism 3. Supporting mechanisms 4 are provided on both sides of the connecting mechanism 3.

[0032] The connecting mechanism 3 includes a pipe clamp 33, a mounting plate 34 is provided on one side of the pipe clamp 33, the column 2 is connected to the side wall of the mounting plate 34 through the pipe clamp 33, a first protective plate 31 is provided on one side of the guardrail 1, a protective component 32 is provided on the other side of the guardrail 1, and a threaded post 35 is connected to the side wall of the mounting plate 34. One end of the threaded post 35 passes through the positioning hole 11 and is fixedly connected to the first protective plate 31.

[0033] The support mechanism 4 includes a support frame 41, a first rotating seat 43 is fixedly connected to the side wall of the support frame 41, and pads 36 are fixedly connected to both ends of the side wall of the mounting plate 34. A rotating assembly 44 is provided on the side wall of the pads 36, and a rotating rod 42 is rotatably connected between the first rotating seat 43 and the rotating assembly 44.

[0034] In this embodiment, the guardrail is composed of multiple sets of guardrail panels 1 and multiple sets of posts 2. Two adjacent guardrail panels 1 are connected to the posts 2 through the positioning holes 11 at the outer ends. Each post 2 is also provided with a support mechanism 4 on both outer sides. The support mechanism 4 and the guardrail panel 1 form a triangular support structure to strengthen the stability of the connection between the post 2 and the guardrail panel 1.

[0035] The top of the column 2 is provided with an annular groove 22, and the inside of the pipe clamp 33 is provided with a matching groove. When the connecting mechanism 3 is fixedly installed to the column 2, the pipe clamp 33 is sleeved on the outside of the column 2 and the pipe clamp 33 is made to fit against the outer wall of the column 2, so that the pipe clamp 33 and the annular groove 22 are fastened together, and the connecting mechanism 3 is stably installed on the top of the column 2. The first protective plate 31 and the protective component 32 are respectively set on both sides of the guardrail 1. The first protective plate 31 is fixed to the threaded post 35, and the other end of the threaded post 35 is connected to the mounting plate 34 by threads. The protective component 32 is inserted into the surface of the first protective plate 31. When the connecting mechanism 3 is installed, the first protective plate 31 is fitted against the outside of the guardrail 1, and the protective component 32 is pushed towards the first protective plate 31, so that the first protective plate 31 and the protective component 32 are clamped on both sides to fix the guardrail 1, so as to achieve the effect of installing the guardrail 1 on the column 2.

[0036] The support frame 41 is a groove-shaped plate, so the support frame 41 can be snapped onto the outside of the guardrail plate 1. A rotating rod 42 is set between the support frame 41 and the pad 36. The rotating rod 42 provides lateral support to the support frame 41, thereby supporting the guardrail plate 1 at the connection of the support frame 41. The number of anti-collision support points of the guardrail plate 1 is increased from one to three, which increases the overall support and connection of the guardrail plate 1, reduces the degree of deformation when a vehicle collides with the guardrail plate 1, and reduces the maintenance cost after an accident. Example 2

[0037] according to Figure 1 , Figure 3 and Figure 4As shown, a base 21 is fixedly connected to the bottom end of the column 2, and annular grooves 22 are formed on the outer side wall of the column 2. A positioning plate 410 is provided at both the top and bottom of the support frame 41, and the positioning plate 410 is made of aluminum alloy. First mounting holes 330 are formed at both ends of the side wall of the pipe clamp 33, and second mounting holes 340 are formed at both ends of the mounting plate 34. A screw 39 is slidably connected to the side wall of the pad 36, and one end of the screw 39 passes through the second mounting hole 340 and the first mounting hole 330 and is threaded with a second nut 38.

[0038] In this embodiment, a positioning plate 410 is provided at the top of the support frame 41. The positioning plate 410 is made of easily deformable aluminum alloy. Before the support frame 41 is installed on the guardrail plate 1, the positioning plate 410 is in a straight state. The rotating rod 42 has a variety of different lengths. The appropriate length of the rotating rod 42 can be selected according to the usage situation so that the rotating rod 42 is connected to the first rotating seat 43 and the second rotating seat 441. After the angle of the rotating rod 42 is adjusted, the two positioning plates 410 are bent inward so that the bent part of the positioning plate 410 is engaged with the guardrail plate 1, thereby fixing the support position of the support frame 41 on the guardrail plate 1. A base 21 is provided at the bottom of the column 2. The base 21 is installed above the ground with expansion screws, and the mounting plate 34 and the pad 36 are fixed by screws 39 so that the pipe clamp 33 can stably install the column 2 on the side wall of the mounting plate 34. Example 3

[0039] according to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the rotating assembly 44 includes a second rotating seat 441 and a rotating column 444. Both ends of the rotating column 444 pass through both sides of the second rotating seat 441 and are fixedly connected with anti-slip stripes. A sealing ring 442 is movably connected to the outer wall of the rotating column 444. A connecting column 443 is fixedly connected between the sealing ring 442 and the screw 39. The rotating rod 42 is fixedly connected to the rotating column 444. The protective assembly 32 includes a side support plate 321 and a second protective plate 322. A first nut 323 is provided between the side support plate 321 and the second protective plate 322. Two baffles 324 are fixedly connected to the side wall of the second protective plate 322. The first nut 323 is threadedly connected to a threaded column 35. A spring 37 is fixedly connected between the side support plate 321 and the mounting plate 34.

[0040] In this embodiment, a protective component 32 is provided on the back of the guardrail 1. Before the post 2 is installed on one side of the mounting plate 34, the hole on the second protective plate 322 is aligned with the threaded post 35. The second protective plate 322 is sleeved on the threaded post 35, and the second protective plate 322 is fastened to the other side of the guardrail 1 using the first nut 323. Then, a side support plate 321 is sleeved on one side of the second protective plate 322. The side support plate 321 has an inverted C-shaped structure. The first nut 323 is accommodated in the cavity of the side support plate 321 and the second protective plate 322. A spring 37 is set on the outside of the threaded post 35. Finally, the mounting plate 34 is connected to the threaded post 35. The spring 37 plays a buffering role on the side support plate 321. When the impact force on one side is transmitted to the side wall of the guardrail 1, the deformation of the guardrail 1 can be reduced by the action of the spring 37.

[0041] In addition, one end of the rotating rod 42 is rotatably connected to the first rotating seat 43, and the other end of the rotating rod 42 is fixedly connected to the rotating column 444. The rotating column 444 is movably connected to the second rotating seat 441 through the sealing ring 442. When the sealing ring 442 is tightly fastened to the outside of the rotating column 444, the anti-slip stripes on the surface of the rotating column 444 facilitate contact with the shaft hole of the second rotating seat 441, increasing the friction of the rotating column 444 and fixing the connection position between the rotating rod 42 and the rotating assembly 44. Therefore, before installing the pipe clamp 33, according to the support... The frame 41 rotates the rotating rod 42 of a suitable length to the support position of the guardrail plate 1. First, adjust the installation angle of the rotating rod 42. After the connection angle between the rotating rod 42 and the rotating component 44 is adjusted, the pad 36 and the mounting plate 34 are connected by screws 39. While the screws 39 are being installed, they will also drive the connecting column 443 to move to one side, so that the sealing ring 442 tightens the rotating column 444 and fixes it to the second rotating seat 441, thus achieving the effect of stable installation of the rotating rod 42. The rotating rod 42 plays a buffering role against the impact force at the support frame 41. Example 4

[0042] according to Figure 1 As shown, the guardrail panel 1 comprises a panel body and the following raw materials in parts by weight: 1000-1200 parts by weight of polyester resin, 70-110 parts by weight of titanium dioxide, 100-170 parts by weight of barium sulfate powder, 4-5 parts by weight of bentonite, 4-6 parts by weight of anti-flash rust additive, 3.5-4 parts by weight of wax powder, 0.7-1 parts by weight of sanding agent, 5-6 parts by weight of leveling agent, 2-4 parts by weight of benzoin, 0.4-1 parts by weight of defoamer, 0.1-3 parts by weight of carbon black and 1.5-2 parts by weight of iron oxide yellow.

[0043] In this embodiment, polyester resin is mixed with the other ingredients mentioned above and then mixed evenly. The powder is obtained by extrusion, cooling, crushing, grinding and sieving. The powder coating is then evenly sprayed onto the outer surface of the panel using an electrostatic spraying machine. After curing at 200 °C for 15 min, the panel is removed and cooled to obtain a weather-resistant guardrail panel 1.

[0044] The usage method and working principle of this device: When installing the guardrail, first, the base 21 is buried in the ground and fixed with expansion screws. Then, cement is poured on top of it to seal it. Finally, the positioning holes 11 of the two guardrail plates 1 are connected to the connecting mechanism 3.

[0045] Then, place the first protective plate 31 in front of the guardrail plate 1, so that the threaded post 35 passes through the positioning hole 11, overlap the second protective plate 322 with the threaded post 35 behind, then tighten the first nut 323 so that the second protective plate 322 and the first protective plate 31 clamp and fix the two connected guardrail plates 1, and then overlap the side support plate 321 on the second protective plate 322.

[0046] Then, spring 37 is inserted into the outside of threaded post 35, and threaded post 35 is connected and fixed to mounting plate 34. Next, support frame 41 is sleeved on top of guardrail plate 1, rotating rotating rod 42 to make support frame 41 fit against guardrail plate 1.

[0047] Finally, screw 39 is inserted into pad 36, pipe clamp 33 is sleeved on the outside of column 2, and the end of screw 39 is made to pass through the first mounting hole 330 and connect with the second nut 38. During the connection of screw 39 and pipe clamp 33, screw 39 drives connecting column 443 to move to one side, so that sealing ring 442 tightens rotating column 444 and fixes second rotating seat 441, so that rotating rod 42 no longer rotates, and rotating rod 42 connects guardrail plate 1 and pad 36.

[0048] When the guardrail 1 is impacted near the connecting mechanism 3, the deformation of the guardrail 1 pushes the second protective plate 322 to move. The second protective plate 322 and the mounting plate 34 generate a squeezing force, and the spring 37 deforms to apply a reverse buffering force. The support mechanisms 4 on both sides support the guardrail 1 around the impact point to prevent the guardrail 1 on both sides from deforming.

[0049] When the guardrail 1 is impacted near the support mechanism 4, the deformation of the guardrail 1 pushes the support frame 41 to move, which in turn causes the rotating rod 42 to rotate. The sealing ring 442 provides a certain anti-collision buffer against the friction of the rotating column 444. The connecting mechanism 3 on one side supports the guardrail 1 around the impact point to prevent large-area deformation of the guardrail 1.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
