Description

Technical Field

[0001] The present application relates to the technical field of traffic guardrails, and in particular to a road guardrail. Background Art

[0002] Traffic guardrails are a type of traffic safety facility installed on the outside of the road shoulder, traffic divider, and sidewalk curbs. They absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from going off the road or entering the opposite lane, and minimizing the damage to passengers.

[0003] Guardrails are commonly used in roads, highways and other occasions. Their most common structure is composed of end columns, cross bars, spacers and middle columns. The end columns and middle columns and adjacent middle columns are connected by cross bars. The cross bars are mostly set as two upper and lower bars, and a spacer is set between the two cross bars.

[0004] The above-mentioned road guardrails are often set in the middle of the road to separate traffic, and at the same time can block or stop the original direction of travel of vehicles and pedestrians. However, when a road guardrail is collided or impacted, causing part of the road guardrail to fall or shift significantly, other parts of the road guardrail will also be affected and may also fall or shift significantly. When the entire road guardrail falls or shifts significantly, the normal traffic on the road will be seriously affected, causing traffic jams and may even affect other vehicles on the road. Utility Model Content

[0005] In order to improve the problem that when a part of a road guardrail is impacted, other parts of the road guardrail may also be affected, the present application provides a road guardrail.

[0006] The present application provides a road guardrail, which adopts the following technical solution:

[0007] A road guardrail comprises a plurality of positioning piles arranged at intervals, a plurality of guardrail assemblies and a plurality of fixing assemblies, wherein the positioning piles are fixed on a road surface, and the guardrail assembly comprises a frame and a plurality of buffer plates, wherein the frame is located between adjacent positioning piles, the frame is rotatably connected to adjacent positioning piles, and the plurality of buffer plates are surrounded by the frame; the fixing assembly comprises two fixing members, a plurality of first elastic members and a connecting rope, wherein the two fixing members are respectively located at two ends of the frame, the fixing members are simultaneously passed through the positioning piles and the frame, the two ends of the connecting rope are respectively fixedly connected to the two fixing members, the buffer plate is penetrated with a through hole for the connecting rope to pass through, and the first elastic member drives the fixing member to move in a direction close to the positioning piles.

[0008] By adopting the above technical solution, when the road guardrail is not hit, the frame is fixedly connected to the positioning piles on both sides through the effect of the two fixing members acting as positioning pins, and at this time, the connecting rope is taut and straight, so that the positions of the plurality of buffer plates are fixed; when the road guardrail is hit, the position states of the plurality of buffer plates will change, so that the connecting rope is bent, and after the connecting rope is bent, the two fixing members will be driven to overcome the first elastic member and move in the direction away from the positioning piles, thereby releasing the fixed connection relationship between the frame and the positioning piles on both sides; in the above process, the first elastic member will buffer the impact, and if the impact has been buffered and eliminated before the frame and the positioning piles on both sides are released from the fixed connection relationship, the first elastic member will drive the fixing member to move and reset; if the impact has not been buffered and eliminated after the frame and the positioning piles on both sides are released from the fixed connection relationship, the impact will drive the frame to rotate, and the magnitude of the impact force can be reduced during the rotation of the frame, thereby further playing a buffering role; so that the road guardrail has a good buffering effect, and a part of it can automatically reduce the strength of the connection relationship with other parts according to the magnitude of the impact force after being hit, thereby reducing the probability of affecting other parts of the road guardrail after the position change caused by itself being hit.

[0009] Optionally, the buffer plate is rotatably connected to the frame, and the rotation axis of the buffer plate is vertical.

[0010] By adopting the above technical solution, after the road guardrail is hit, several buffer plates will rotate, and the rotated buffer plates will form a concave space. After the vehicle enters the concave space, the concave space will hinder the vehicle from moving forward and eventually stop the vehicle.

[0011] Optionally, the surface of the buffer plate has an elastic buffer layer.

[0012] By adopting the above technical solution, the buffer layer has elasticity, and when a vehicle collides with the buffer plate, the degree of damage to the vehicle and the buffer plate can be reduced, thereby protecting the safety of the driver.

[0013] Optionally, a plurality of grooves are formed on the buffer layer.

[0014] By adopting the above technical solution, after the vehicle hits the buffer plate and contacts the buffer layer, the several grooves on the buffer layer will increase the friction force on the surface of the buffer layer, thereby further preventing the vehicle from moving forward.

[0015] Optionally, the guardrail assembly further includes a plurality of protective covers for protecting the connecting ropes, wherein the protective covers are fixedly connected to the buffer plate, the protective covers are located at the ends of the perforations, and the protective covers are sleeved on the connecting ropes.

[0016] By adopting the above technical solution, the vehicle hits the buffer plate, causing the buffer plate to rotate and thus causing the connecting rope to deform. The protective cover can protect the connecting rope and prevent the connecting rope from directly contacting the sharp edge of the perforation after the buffer plate rotates, thereby reducing the probability of the connecting rope being damaged or disconnected due to contact with the sharp edge and extending the service life of the connecting rope.

[0017] Optionally, the rotation axis of the frame is located at the bottom of the frame, and the bottom of the frame is against the road surface.

[0018] By adopting the above technical solution, when the road guardrail is hit and causes the frame to rotate, the rotated frame and a number of buffer plates will form an inclined ramp to guide the vehicle under the action of inertia to drive up, thereby eliminating the inertia of the vehicle, and then the vehicle continues to move forward due to inertia, causing the frame to move and drive the positioning piles to move, thereby affecting other parts of the road guardrail.

[0019] Optionally, it also includes a plurality of buffer components, the buffer components include a sliding part and a second elastic part, the bottom of the positioning pile is provided with a first sliding groove for the sliding part to slide in a vertical direction, the guardrail assembly also includes two linkage parts, both ends of the frame body have rotating shafts extending outward, the two linkage parts are respectively arranged on the two rotating shafts, the linkage part is located inside the positioning pile, and the linkage part cooperates with the sliding part; the second elastic part is also located in the first sliding groove, one end of the second elastic part is connected to the bottom groove wall of the first sliding groove, and the other end of the second elastic part is connected to the bottom of the sliding part, and the rotation of the frame body drives the sliding part to slide through the linkage part.

[0020] By adopting the above technical solution, after the road guardrail is hit and causes the frame to rotate, the frame will drive the sliding member to slide through the linkage member. During the sliding process of the sliding member, the force of the second elastic member needs to be overcome, so the second elastic member can buffer the impact, and the second driving member will drive the sliding member to slide and reset, thereby rotating and resetting the frame; the frame still has a buffering effect on the vehicle after rotation, thereby further reducing the probability that the vehicle continues to move forward and causes the frame to move after being hit, thereby driving the positioning pile to move, thereby further reducing the impact of the frame rotation on other parts of the road guardrail.

[0021] Optionally, the buffer assembly includes a plurality of sliding members and a plurality of second elastic members, and the linkage member cooperates with the plurality of sliding members simultaneously.

[0022] By adopting the above technical solution, when the road guardrail is hit and causes the frame to rotate, the rotation of the linkage member will drive the multiple sliding members to slide, and the buffering effect of the multiple second elastic members on the impact will be doubled, which can greatly improve the buffering effect of the buffer assembly.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When a part of the road guardrail is hit, the part can weaken its connection with other parts of the road guardrail according to the magnitude of the impact force, thereby reducing the probability that the other parts of the road guardrail will be affected by the impact itself;

[0025] 2. Road guardrails have a better buffering effect. After a vehicle collides with a road guardrail, the force exerted by the vehicle on the impacted part can be eliminated promptly and effectively, reducing the impact of the impact on the road guardrail, thereby reducing the probability of the road guardrail toppling over or having a large position displacement.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] An embodiment of the present application discloses a road guardrail.

[0034] Reference Figure 1 and Figure 2The road guardrail includes a plurality of positioning piles 1, a plurality of guardrail components 2, a plurality of fixing components 3 and a plurality of buffer components 4. The plurality of positioning piles 1 are evenly spaced along the center line of the road, and the positioning piles 1 are fixedly installed on the road surface; the guardrail components 2 are installed between adjacent positioning piles 1, and the guardrail components 2 are fixed relative to the adjacent positioning piles 1 through the fixing components 3; when a vehicle hits the guardrail component 2, the guardrail component 2 will absorb and eliminate the impact of the vehicle through the buffer component 4, thereby reducing the impact of the vehicle impact on the guardrail component 2, and further reducing the probability of other guardrail components 2 being affected.

[0035] Reference Figure 2 The bottom of the positioning pile 1 has a counterweight part 11, the mass of the counterweight part 11 is much greater than the mass of other parts of the positioning pile 1, and the counterweight part 11 is buried under the road surface, so that the positioning pile 1 is firmly fixed relative to the road.

[0036] Reference Figure 1 and Figure 2 The guardrail assembly 2 includes a frame 21 and a plurality of buffer plates 22. The frame 21 surrounds the plurality of buffer plates 22. The buffer plates 22 are rotatably connected to the frame 21. The rotation axis 211 of the buffer plates 22 is perpendicular to the ground, and the buffer plates 22 are symmetrical along their own rotation axis 211. The plurality of buffer plates 22 are distributed at equal intervals, and there is always a gap between adjacent buffer plates 22 during the rotation of the buffer plates 22.

[0037] Reference Figure 1 and Figure 3 The surface of the buffer plate 22 has a buffer layer 23, the buffer layer 23 is elastic, and a plurality of grooves 231 are formed at equal intervals on the buffer layer 23, the plurality of grooves 231 make the surface of the buffer layer 23 uneven, increase the friction between the vehicle and the surface of the buffer layer 23, and thus prevent the vehicle from continuing to move forward after colliding with the buffer plate 22. In this embodiment, the buffer layer 23 is preferably made of rubber material.

[0038] Reference Figure 2 The bottom of the frame 21 is against the road surface, and both ends of the frame 21 extend outward with a rotation axis 211, which is located at the bottom of the frame 21, and the frame 21 is rotatably connected to the positioning piles 1 on both sides through the two rotation axes 211, and the rotation axis 211 line of the frame 21 is perpendicular to the rotation axis 211 line of the buffer plate 22.

[0039] Reference Figure 2 and Figure 4The fixing assembly 3 includes two fixing members 31, two first elastic members 32 and a connecting rope 33. One end of the fixing member 31 is a plug-in portion 311, and the other end is a connecting portion 312, and the fixing member 31 also has a protrusion 313 between the plug-in portion 311 and the connecting portion 312. A plug-in slot 12 for inserting the plug-in portion 311 is provided on one end surface of the positioning pile 1 close to the other positioning pile 1, and a second sliding slot 212 for sliding the fixing member 31 is provided on one end of the frame 21 close to the positioning pile 1, and the fixing member 31 slides in the horizontal direction. When the frame 21 is in a vertical state, the second sliding slot 212 is communicated with the plug-in slot 12. When the fixing member 31 slides to the extreme position in the direction close to the adjacent positioning pile 1, the plug-in portion 311 is inserted into the plug-in slot 12, and the connecting portion 312 is still located in the second sliding slot 212, and at this time the frame 21 cannot rotate under the action of the fixing member 31; when the fixing member 31 slides to the extreme position in the direction away from the adjacent positioning pile 1, the plug-in portion 311 leaves the plug-in slot 12, and the connecting portion 312 abuts against the bottom of the second sliding slot 212, and at this time the frame 21 can rotate.

[0040] Reference Figure 4 The first elastic member 32 is sleeved on the connecting portion 312, and one end of the first elastic member 32 is fixedly connected to the protruding portion 313, and the other end of the first elastic member 32 is fixedly connected to the bottom of the second sliding groove 212. The first elastic member 32 drives the fixing member 31 to slide toward the direction close to the adjacent positioning pile 1, so that the plug-in portion 311 remains plugged into the plug-in groove 12. In this embodiment, the first elastic member 32 is preferably a compression spring.

[0041] Reference Figure 2 and Figure 4 The two ends of the connecting rope 33 are fixedly connected to the connecting parts 312 of the two fixing members 31 respectively. A clearance hole 213 for the connecting rope 33 to pass through is opened on the frame 21, and the clearance hole 213 is communicated with the second sliding groove 212; the buffer plate 22 is also penetrated with a through hole 221 for the connecting rope 33 to pass through. When the plug-in parts 311 of the two fixing members 31 are both inserted into the plug-in grooves 12, the connecting rope 33 is in a taut state. At this time, the connecting rope 33 is in a straight state. The taut connecting rope 33 will drive the plurality of buffer plates 22 to maintain a position state in the same plane; when the guardrail assembly 2 is hit by a vehicle, the plurality of buffer plates 22 will rotate and cause part of the connecting rope 33 to bend. After the connecting rope 33 is bent and deformed, it will drive the fixing member 31 to slide toward the direction close to the frame body 21, so that the plug-in parts 311 of the two fixing members 31 are disengaged from the corresponding plug-in grooves 12, thereby weakening the connection relationship between the frame body 21 and the positioning piles 1 on both sides, and the frame body 21 can rotate at this time.

[0042] Reference Figure 2 and Figure 3The guardrail assembly 2 further includes a plurality of protective covers 24, two protective covers 24 are fixedly mounted on each buffer plate 22, and the two protective covers 24 are respectively located at two opening positions of the perforation 221 on the buffer plate 22. The protective cover 24 is sleeved on the connecting rope 33, and the surface of the protective cover 24 is smooth, which can prevent the connecting rope 33 from directly contacting the sharp edge of the opening of the perforation 221, thereby preventing the connecting rope 33 from being broken or disconnected. In this embodiment, the protective cover 24 is preferably made of plastic.

[0043] Reference Figure 2 and Figure 5 The buffer assembly 4 includes two linkage members 41, four sliding members 42 and four second elastic members 43. The two rotating shafts 211 of the frame 21 penetrate into the interior of the positioning piles 1 on both sides respectively, and the interior of the positioning piles 1 is provided with four first sliding grooves 13 for the sliding members 42 to slide along the vertical direction. Sliding members 42 are installed on both sides of the linkage member 41, and the second elastic member 43 is also installed in the first sliding groove 13, and the second elastic member 43 is located below the sliding member 42. One end of the second elastic member 43 is fixedly connected to the bottom of the sliding member 42, and the other end of the second elastic member 43 is fixedly connected to the bottom groove wall of the first sliding groove 13. The second elastic member 43 drives the sliding member 42 to be fixed in the first sliding groove 13. The rotation of the frame 21 will drive the linkage member 41 to rotate, and the rotation of the linkage member 41 will simultaneously drive the sliding members 42 on both sides to slide against the force of the second elastic member 43. At this time, the second elastic member 43 will prevent the frame 21 from rotating, thereby playing a buffering role in the collision of the vehicle. In this embodiment, the second elastic member 43 is preferably a common spring, and the linkage relationship between the linkage member 41 and the sliding member 42 is preferably the same as the linkage relationship between the gear and the rack.

[0044] The implementation principle of a road guardrail in the embodiment of the present application is:

[0045] When a vehicle hits the guardrail assembly 2, the vehicle will contact with a plurality of buffer plates 22, and the buffer layer 23 on the buffer plate 22 can absorb part of the impact, while a plurality of grooves 231 on the buffer layer 23 can prevent the vehicle from moving forward; after the vehicle contacts with a plurality of buffer plates 22, the buffer plate 22 will be driven to rotate, and the rotation of the buffer plate 22 will cause the connecting rope 33 to bend and deform, and the bending and deformation of the connecting rope 33 will drive the fixing member 31 to slide, so that the plug-in cooperation between the plug-in portion 311 and the plug-in groove 12 is released, thereby weakening the connection relationship between the frame 21 and the adjacent positioning pile 1, and thus reducing the guardrail assembly. 2 affects other guardrail components 2 after being hit; after the fixed relationship between the frame 21 and the adjacent positioning pile 1 is released, the impact will drive the frame 21 to rotate, and the frame 21 will form a ramp for the vehicle to drive on after rotation, thereby reducing the impact of the vehicle on the guardrail component 2 and further preventing the vehicle from moving forward; after the frame 21 rotates, the sliding member 42 will be driven by the linkage member 41 to slide against the force of the second elastic member 43, and the second elastic member 43 will prevent the frame 21 from rotating, thereby playing a buffering role on the impact of the vehicle, further reducing the impact of the vehicle impact on the guardrail component 2.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
