Description

Technical Field

[0001] This utility model belongs to the field of lane guardrail technology, and in particular relates to a collision-resistant guardrail for highway operation safety. Background Technology

[0002] With economic development, traffic flow on highways is increasing day by day. On some busy highway sections, thousands of vehicles pass by every hour. The types of vehicles are also very diverse, including small cars, large buses, heavy trucks, etc. Different types of vehicles have great differences in driving speed, body size and handling performance. For example, due to their large weight, heavy trucks have a long braking distance and it is difficult for them to brake as quickly as small cars in emergency situations.

[0003] However, in the use of existing highway safety crash barriers, the barriers are not effective at buffering during vehicle collisions. When the front of the vehicle hits the barrier, the vehicle frame structure will directly bear a huge impact force, which will cause serious deformation of the frame and pose a potential safety threat to the driver. Utility Model Content

[0004] The purpose of this utility model is to provide a safety anti-collision guardrail for highway operation. By setting up a buffer mechanism, it solves the problem that the safety anti-collision guardrail is not easy to effectively buffer during vehicle collisions. When the front of the vehicle hits the guardrail, the frame structure will directly bear huge impact force, which will cause serious deformation of the frame and pose a potential safety threat to the driver.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a highway operation safety anti-collision guardrail, including a guardrail frame, on which a plurality of buffer mechanisms and a plurality of deceleration mechanisms are provided;

[0007] The buffer mechanism includes a buffer assembly and a rotating assembly. The buffer assembly includes a fixed rod fixedly connected to the guardrail frame. A fixed block is fixedly connected to the outer wall of the fixed rod. Several L-shaped plates are fixedly connected to the upper part of the fixed block. Several connecting rods are fixedly connected between the several L-shaped plates.

[0008] Furthermore, two fixing plates are slidably connected to the outer walls of several connecting rods, and two springs are sleeved on the outer walls of several connecting rods. The sides of several springs that are far apart from each other are fixedly connected to L-shaped plates, and the sides of several L-shaped plates that are close to each other are fixedly connected to fixing plates. An arched plate is fixedly connected to the sides of several fixing plates that are close to each other.

[0009] Furthermore, the rotating assembly includes several fixed blocks II fixedly connected to the corresponding L-shaped plate, and hollow rods I fixedly connected to the outer walls of each of the several fixed blocks II, and rectangular rods slidably connected inside each of the several hollow rods I.

[0010] Furthermore, two springs are fixedly connected to the side of several rectangular rods near the fixing block one, and the side of several springs away from the rectangular rods is fixedly connected to the fixing block two. A crash barrier is provided on the top of the fixing rod.

[0011] Furthermore, the anti-collision barrel has two circular grooves, and a slider is fixedly connected to the side of the rectangular rod away from the L-shaped plate, and the slider is slidably connected in the circular groove.

[0012] Furthermore, the deceleration mechanism includes a geared disc fixedly connected to the outer wall of the fixed rod, and a plurality of fixed blocks three are fixedly connected to the outer wall of the anti-collision barrel, and hollow rods two are fixedly connected to the outer walls of the plurality of fixed blocks three.

[0013] Furthermore, each of the fixed blocks three has two sliding rods fixedly connected to the side away from the anti-collision barrel, and the side of each sliding rod away from the fixed block three slides into the conical rod. The outer wall of each sliding rod is slidably connected to a conical rod. If each conical rod is adapted to the gear plate, a spring three is sleeved on the outer wall of each sliding rod. The side of each spring three near the fixed rod is fixedly connected to the conical rod, and the side of each spring three away from the fixed rod is fixedly connected to the fixed block three.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a buffer mechanism, after installation, when the device is impacted, it will first contact the anti-collision barrel. The anti-collision barrel will initially rotate due to the external force. As it rotates, the slider will slide within the circular groove. Subsequently, the anti-collision barrel will be compressed. Due to the good toughness of the anti-collision barrel, when it is compressed, the rectangular rod will compress the second spring. The compression of the second spring will act on the second fixed block. When the rectangular rod is compressed, it will slide within the hollow rod. Upon impact, the anti-collision barrel will retract inwards. When the anti-collision barrel retracts, it will first contact the arched plate. When the plate is compressed, it will apply the compressive force to both ends. When the arched plate extends to both ends, the fixed plate will be pushed. When the fixed plate slides, it will slide on the connecting rod. When the fixed plates are pushed, they move away from each other. When the fixed plates move away from each other, the spring will be compressed. The compressive force of the spring will act on the L-shaped plate to achieve a buffering effect. When the vehicle crashes, the anti-collision barrel will be the first to receive the external force and rotate. Its slider slides on the circular groove, dispersing the initial collision energy, gradually reducing the impact force of the vehicle, mitigating the damage to the vehicle structure, and reducing maintenance costs and the risk of scrapping.

[0016] 2. By setting up a deceleration mechanism, when the crash barrier rotates, the fixed block three will rotate accordingly. When the fixed block three rotates, it will simultaneously rotate the hollow rod two, which in turn will rotate the cone rod. When the cone rod rotates, there will be some resistance due to the restriction of the gear plate. After the crash barrier is squeezed, the fixed block three will retract inward. When the fixed block three retracts, the hollow rod two will be moved along with it. When the fixed block three retracts inward, the sliding rod will also slide inward into the cone rod. When the fixed block three retracts inward, it will push the spring three to retract inward. When the spring three retracts, the extension force will increase. At this time, the thrust on the cone rod will become stronger and stronger, thus increasing the force of contact between the cone rod and the gear plate. Therefore, the resistance will be greater and the deceleration effect will be more obvious. By generating and changing the resistance between the cone rod and the gear plate, a highly efficient deceleration function is achieved. It can initially reduce the impact speed of the vehicle, effectively reduce the severity of the initial collision between the vehicle and the guardrail, and reduce the risk of vehicle structural damage, such as reducing the possibility of damage to the exterior parts of the vehicle body and local deformation of the frame.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5As shown, this utility model is a highway safety anti-collision guardrail, including a guardrail frame 1. The guardrail frame 1 is equipped with several buffer mechanisms 2 and several deceleration mechanisms 3. Each buffer mechanism 2 includes a buffer assembly 21 and a rotating assembly 22. The buffer assembly 21 includes a fixed rod 211 fixedly connected to the guardrail frame 1. A fixed block 212 is fixedly connected to the outer wall of the fixed rod 211. Several L-shaped plates 213 are fixedly connected to the upper part of the fixed block 212. Several connecting rods 214 are fixedly connected between the L-shaped plates 213. Two fixed plates 215 are slidably connected to the outer walls of the connecting rods 214. Two springs 216 are sleeved on the outer walls of the connecting rods 214. The sides of the springs 216 that are far apart from each other are fixedly connected to the L-shaped plates 213, and the sides of the L-shaped plates 213 that are close together are fixedly connected to the fixed plates 215. An arched plate 217 is fixedly connected to the sides of the fixed plates 215 that are close together. The rotating assembly 22 includes several fixed blocks 221 fixedly connected to the corresponding L-shaped plate 213. Hollow rods 222 are fixedly connected to the outer walls of each fixed block 221. Rectangular rods 223 are slidably connected inside each hollow rod 222. Two springs 224 are fixedly connected to the side of each rectangular rod 223 near the fixed block 212. The side of each spring 224 away from the rectangular rod 223 is fixedly connected to the fixed block 221. A crash barrier 225 is provided on the fixed rod 211. Two circular grooves 226 are provided on the crash barrier 225. A slider 227 is fixedly connected to the side of the rectangular rod 223 away from the L-shaped plate 213. The slider 227 is slidably connected in the circular groove 226. By setting up a buffer mechanism, when a vehicle is impacted, the crash barrier rotates first due to the external force. Its slider slides in the circular groove, dispersing the initial collision energy, gradually reducing the impact force of the vehicle, mitigating the damage to the vehicle structure, and reducing maintenance costs and the risk of scrapping.

[0028] The deceleration mechanism 3 includes a gear disc 311 fixedly connected to the outer wall of the fixed rod 211. Several fixed blocks 312 are fixedly connected to the outer wall of the anti-collision barrel 225. Hollow rods 313 are fixedly connected to the outer walls of each of the fixed blocks 312. Two sliding rods 314 are fixedly connected to the side of each fixed block 312 away from the anti-collision barrel 225. The side of each sliding rod 314 away from the fixed blocks 312 slides into a cone rod 315. Cone rods 315 are slidably connected to the outer walls of each sliding rod 314. If each cone rod 315 is compatible with the gear disc 311, then... Each sliding rod 314 has a spring 316 fitted on its outer wall. The side of several springs 316 closest to the fixed rod 211 is fixedly connected to the cone rod 315, and the side of several springs 316 furthest from the fixed rod 211 is fixedly connected to the fixed block 312. By setting up a deceleration mechanism, the generation and change of resistance between the cone rod and the gear plate achieve a high-efficiency deceleration function, which can initially reduce the impact speed of the vehicle, effectively reduce the severity of the initial collision between the vehicle and the guardrail, and reduce the risk of vehicle structural damage, such as reducing the possibility of damage to the exterior parts of the vehicle body and local deformation of the frame.

[0029] A specific application of this embodiment is as follows: In use, the device is first placed in the appropriate position. After installation, when the device is impacted, it first contacts the anti-collision barrel 225. The anti-collision barrel 225 will rotate due to the external force. When the anti-collision barrel 225 rotates, the slider 227 will slide within the circular groove 226. Subsequently, the anti-collision barrel 225 will be compressed. Because the anti-collision barrel 225 has good toughness, when the anti-collision barrel 225 is compressed, the rectangular rod 223 will compress the spring 224, and the spring 224... The compression applied to 24 will act on the fixed block 221. When the rectangular rod 223 is compressed, it will slide inside the hollow rod 222. When impacted, the anti-collision barrel 225 will retract inward. When the anti-collision barrel 225 retracts, it will first contact the arched plate 217. When the arched plate 217 is compressed, it will apply the compressive force to both ends. When the arched plate 217 extends to both ends, the fixed plate 215 will be pushed. When the fixed plate 215 slides, it will slide on the connecting rod 214. When the fixed plates 215 are pushed, they move away from each other. When the fixed plates 215 move away from each other, the spring 216 will be compressed. The compressive force on the spring 216 will act on the L-shaped plate 213, achieving a buffering effect. When the anti-collision barrel 225 rotates, the fixed block 312 will rotate accordingly. When the fixed block 312 rotates, it will simultaneously rotate the hollow rod 313, which will then rotate the cone rod 315. When the cone rod 315 rotates, it will experience some resistance due to the restriction of the gear plate 311. After the anti-collision barrel 225 is compressed, the fixed block 312 will... 12 will retract inward. When the fixed block 312 retracts, the hollow rod 2 313 will move along with it. When the fixed block 312 retracts inward, the slide rod 314 will also slide into the cone rod 315 at the same time. When the fixed block 312 moves inward, it will push the spring 316 to retract inward. When the spring 316 retracts, the extension force will increase. At this time, the thrust on the cone rod 315 will become stronger and stronger. As a result, the force of the cone rod 315 contacting the gear plate 311 will increase, and the resistance will be greater and the deceleration effect will be more obvious.
