Description

Technical Field

[0001] The utility model relates to an anti-collision guardrail with high safety. Background Art

[0002] Municipal bridges generally refer to bridges built on rivers within the city, and overpasses where roads interchange or roads cross railways. Guardrails are usually installed on both sides of municipal bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, and beautifying the bridge structure.

[0003] Among the existing utility models in China, the publication number CN215830171U discloses a collision-proof guardrail for municipal bridges, including a guardrail body and a connecting column, the connecting column is connected to the ground, a connecting rod is provided at the bottom of the guardrail body, an automatic filling device is provided at the bottom of the connecting rod, and limiting devices are provided on both sides of the connecting column. The automatic filling device includes a groove, a spring, a support rod, a base, a counterweight and a limit rod, the limit rod cooperates with the limit device, the groove is located at the bottom of the connecting rod, the base cooperates with the groove, one end of the spring is connected to the top of the groove, one end of the spring is connected to the support rod, the end of the support rod away from the spring is connected to the base, the end of the base away from the support rod is connected to the counterweight, and the limit rod is connected to both ends of the base, which solves the problem that the safety guardrail cannot fit the ground.

[0004] Referring to the above-mentioned municipal bridge anti-collision guardrail, the anti-collision guardrail adopts a single support rod for protection, and the anti-collision guardrail is a rigid structure as a whole, which cannot effectively buffer the impact of the collision, making the overall protection effect of the anti-collision guardrail relatively poor, and it is easy to be damaged by vehicles, so that the vehicle rushes out of the bridge and falls off the bridge deck, causing heavy casualties. In addition, after the accident occurs, the anti-collision guardrail cannot effectively warn the passing vehicles, so that the passing vehicles cannot notice the accident site in time, causing the secondary accident. Therefore, how to better intercept vehicles and better remind passing vehicles to avoid the occurrence of secondary accidents is an important problem that needs to be solved in the design of high-safety anti-collision guardrails. Utility Model Content

[0005] The utility model provides a highly safe anti-collision guardrail in order to solve the problem of better intercepting vehicles and better reminding passing vehicles to avoid the occurrence of secondary accidents.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] The utility model provides a highly safe anti-collision guardrail, comprising a fixed mounting plate, a guardrail is fixedly arranged on the top of the fixed mounting plate, and further comprising:

[0008] A buffer guardrail structure; the buffer guardrail structure is arranged on one side of the guardrail;

[0009] A vehicle blocking structure, wherein the vehicle blocking structure is arranged on a fixed mounting plate, and the vehicle blocking structure and the buffer guardrail structure cooperate with each other to block the vehicle;

[0010] A warning structure is arranged on the top of the guardrail and the buffer guardrail structure.

[0011] Preferably, the guardrail includes guardrail support vertical plates and guardrail support cross bars, the guardrail support vertical plates are fixedly connected to the top outer side wall of the fixed mounting plate at equal distances, and the guardrail support vertical plates are fixedly connected to the guardrail support cross bars at equal distances.

[0012] Preferably, the width of the bottom end of the guardrail support vertical plate is three times the width of the top end.

[0013] In the present technical solution, the width of the bottom end of the guardrail support vertical plate is relatively large, so that the guardrail support vertical plate is supported more stably.

[0014] Preferably, the buffer guardrail structure includes guardrail vertical plates, guardrail cross bars, buffer springs and telescopic rods, the buffer springs and telescopic rods are fixedly connected to the side walls of the guardrail supporting vertical plates at equal distances, the telescopic rods are located inside the buffer springs, the other ends of the buffer springs and the telescopic rods are fixedly connected to the guardrail vertical plates, and the guardrail vertical plates are fixedly connected to the guardrail cross bars at equal distances between each other.

[0015] In the present technical solution, when a vehicle loses control and hits a guardrail, the front of the vehicle first contacts the guardrail vertical plates and the guardrail cross bars. The guardrail vertical plates and the guardrail cross bars move toward the guardrail under the action of the vehicle impact, and the buffer spring and the telescopic rod are compressed. The elastic force generated by the compression of the buffer spring and the impact force of the collision offset each other, thereby reducing the impact force transmitted to the guardrail supporting vertical plates and the guardrail supporting cross bars, reducing the possibility of damage to the guardrail, and thus better blocking the vehicle.

[0016] Preferably, the guardrail vertical plate is in an "L"-shaped structure, the top of the guardrail vertical plate is overlapped on the top of the guardrail supporting vertical plate, and the corners of the guardrail vertical plate are arranged in an arc-shaped structure.

[0017] In the present technical solution, the corners of the vertical plates of the guardrail are in an arc shape, which can prevent the sharp corners from causing damage to passers-by.

[0018] Preferably, the car-blocking structure includes a car-blocking block, tire-breaking spikes and an arc-shaped groove, the car-blocking block is fixedly connected to the top outer wall of the fixed mounting plate at equal distances, an arc-shaped groove is provided on the side of the car-block away from the guardrail, the car-block is inclined on the side wall close to the guardrail, and tire-breaking spikes are fixedly connected to the inner wall of the arc-shaped groove at equal distances, and the tire-breaking spikes are inclined upward.

[0019] In this technical solution, the block blocks the wheel, the side wall of the wheel fits with the arc groove on the block, and the tire-puncturing spikes puncture the tire of the vehicle under the pressure of the wheel and the force of rotation. After the tire is punctured, the friction resistance between the wheel and the bridge surface and between the wheel and the block increases. The increase in friction resistance can slow down the speed of the vehicle and further reduce the impact force of the vehicle, thereby further blocking the vehicle.

[0020] Preferably, the vehicle blocking blocks and the guardrail vertical plates are arranged staggered with respect to each other.

[0021] In this technical solution, when the vertical plate of the guardrail is hit, the vehicle blocking block can be better exposed to further block the vehicle.

[0022] Preferably, the warning structure includes reflector plate 1, a connecting block, reflector plate 2 and a connecting rod, the connecting block is fixedly connected to the top outer wall of the guardrail vertical plate, the top of the connecting block is fixedly connected to reflector plate 1, the connecting rod is fixedly connected to the side wall of the guardrail supporting crossbar, and the top of the connecting rod is fixedly connected to reflector plate 2.

[0023] Preferably, the reflective plate 1 and the reflective plate 2 are of the same size, and the side wall of the reflective plate 2 is slidably attached to the back surface of the reflective plate 1.

[0024] In this technical solution, when the guardrail vertical plate moves during a collision, it will drive the connecting block to move, and the connecting block will drive the reflector plate 1 to move, so that the reflector plate 1 moves away from the front of the reflector plate 2, so that the reflector plate 2 is exposed.

[0025] Preferably, the first reflector is a white reflector, and the second reflector is a red reflector.

[0026] In this technical solution, the white reflector can reflect the vehicle's lights, improve the vehicle's visibility, and increase driving safety. When no accident occurs, the reflector can play a better warning and auxiliary role. The red reflector is brighter and more eye-catching, so the driver can notice it from a distance whether during the day or at night, thereby better reminding the driver to pay attention and avoid accident-free places to avoid secondary accidents.

[0027] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0028] The positive and progressive effects of the utility model are:

[0029] 1. The guardrail and buffer guardrail structure form two layers of protection, which is convenient to increase the strength of the anti-collision guardrail and ensure the safety of the vehicle.

[0030] 2. The guardrail vertical plates and guardrail cross bars move toward the guardrail under the action of the vehicle collision, and the elastic force generated by the compression of the buffer spring and the impact force of the collision offset each other, thereby reducing the impact force transmitted to the guardrail supporting vertical plates and guardrail supporting cross bars, reducing the possibility of damage to the guardrail, thereby better blocking vehicles. The block blocks block the wheels, and the tire-breaking spikes puncture the tires of the vehicles. After the tires are punctured, the friction resistance between the wheels and the bridge deck and between the wheels and the block blocks is increased, which can slow down the speed of the vehicle and further reduce the impact force of the vehicle, thereby further blocking the vehicle, facilitating better interception of the vehicle and preventing the vehicle from rushing out of the bridge deck and falling.

[0031] 3. When the vertical plate of the guardrail moves during the collision, it will drive the connecting block to move, and the connecting block will drive the reflector 1 to move, so that the reflector 1 moves away from the front of the reflector 2. The reflector 2 adopts a red reflector. The color of the red reflector is brighter and more eye-catching, which is convenient for better reminding the driver to pay attention and avoid the accident-free place to avoid the occurrence of a secondary accident.

[0040] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0041] like Figure 1-6 As shown, the anti-collision guardrail with high safety includes a fixed mounting plate 1, a guardrail 2 is fixedly arranged on the top of the fixed mounting plate 1, and also includes:

[0042] A buffer guardrail structure 3; the buffer guardrail structure 3 is arranged on one side of the guardrail 2;

[0043] A vehicle blocking structure 4, wherein the vehicle blocking structure 4 is arranged on the fixed mounting plate 1, and the vehicle blocking structure 4 and the buffer guardrail structure 3 cooperate with each other to block the vehicle;

[0044] The warning structure 5 is arranged on the top of the guardrail 2 and the buffer guardrail structure 3.

[0045] The guardrail 2 includes guardrail support vertical plates 201 and guardrail support cross bars 202. The guardrail support vertical plates 201 are fixedly connected to the top outer side wall of the fixed mounting plate 1 at equal distances, and the guardrail support vertical plates 201 are fixedly connected to the guardrail support cross bars 202 at equal distances between each other.

[0046] The width of the bottom end of the guardrail support vertical plate 201 is three times the width of the top end.

[0047] The width of the bottom end of the guardrail support vertical plate 201 is relatively large, so that the guardrail support vertical plate 201 is supported more stably.

[0048] The buffer guardrail structure 3 includes a guardrail vertical plate 301, a guardrail cross bar 302, a buffer spring 303 and a telescopic rod 304. The buffer spring 303 and the telescopic rod 304 are fixedly connected to the side wall of the guardrail support vertical plate 201 at an equal distance. The telescopic rod 304 is located inside the buffer spring 303. The other ends of the buffer spring 303 and the telescopic rod 304 are fixedly connected to the guardrail vertical plate 301. The guardrail vertical plates 301 are fixedly connected to the guardrail cross bars 302 at an equal distance between each other.

[0049] When a vehicle loses control and hits the guardrail, the front of the vehicle first contacts the guardrail vertical plate 301 and the guardrail cross bar 302. The guardrail vertical plate 301 and the guardrail cross bar 302 move toward the guardrail 2 under the action of the vehicle impact, and the buffer spring 303 and the telescopic rod 304 are compressed. The elastic force generated by the compression of the buffer spring 303 and the impact force of the collision offset each other, thereby reducing the impact force transmitted to the guardrail support vertical plate 201 and the guardrail support cross bar 202, reducing the possibility of damage to the guardrail 2, thereby better blocking the vehicle.

[0050] The guardrail vertical plate 301 is in an "L"-shaped structure, the top of the guardrail vertical plate 301 is overlapped on the top of the guardrail support vertical plate 201, and the corners of the guardrail vertical plate 301 are set to be an arc-shaped structure.

[0051] The corners of the guardrail vertical plate 301 are in an arc shape, which can prevent the sharp corners from causing damage to passers-by.

[0052] The vehicle blocking structure 4 includes a vehicle blocking block 401, tire-breaking spikes 402 and an arc-shaped groove 403. The vehicle blocking block 401 is fixedly connected to the top outer wall of the fixed mounting plate 1 at equal distances. The side of the vehicle blocking block 401 away from the guardrail 2 is provided with an arc-shaped groove 403. The side wall of the vehicle blocking block 401 close to the guardrail 2 is inclined. The tire-breaking spikes 402 are fixedly connected to the inner wall of the arc-shaped groove 403 at equal distances, and the tire-breaking spikes 402 are inclined upward.

[0053] The block 401 blocks the wheel, and the side wall of the wheel fits with the arc groove 403 on the block 401. The tire-puncturing spikes 402 puncture the tire of the vehicle under the pressure of the wheel and the force of rotation. After the tire is punctured, the friction resistance between the wheel and the bridge surface and between the wheel and the block 401 is increased. The increase in friction resistance can slow down the speed of the vehicle and further reduce the impact force of the vehicle, thereby further blocking the vehicle.

[0054] The vehicle blocking block 401 and the guardrail vertical plate 301 are arranged to be staggered with each other.

[0055] When the guardrail vertical plate 301 is hit, the vehicle blocking block 401 can be better exposed to further block the vehicle.

[0056] The warning structure 5 includes a reflector plate 1 501, a connecting block 502, a reflector plate 2 503 and a connecting rod 504. The connecting block 502 is fixedly connected to the top outer wall of the guardrail vertical plate 301, the top of the connecting block 502 is fixedly connected to the reflector plate 1 501, the connecting rod 504 is fixedly connected to the side wall of the guardrail supporting cross bar 202, and the top of the connecting rod 504 is fixedly connected to the reflector plate 2 503.

[0057] The reflective plate 1 501 and the reflective plate 2 503 are of the same size, and the side wall of the reflective plate 2 503 is slidably attached to the back side of the reflective plate 1 501 .

[0058] When the guardrail vertical plate 301 moves during the collision, it will drive the connecting block 502 to move, and the connecting block 502 will drive the reflector 1 501 to move, so that the reflector 1 501 moves away from the front of the reflector 2 503, so that the reflector 2 503 is exposed.

[0059] The reflector plate 1 501 is a white reflector plate, and the reflector plate 2 503 is a red reflector plate.

[0060] The white reflector can reflect the vehicle's lights, improve the vehicle's visibility, and increase driving safety. When no accident occurs, the reflector 501 plays a good warning auxiliary role. The red reflector is brighter and more eye-catching. Whether in the day or at night, the driver can notice it from a farther distance, thereby better reminding the driver to pay attention and avoid accident-free places to avoid secondary accidents.

[0061] When the utility model is in use, the electrical components in the present application are all externally connected to the power supply and the control switch, the fixed mounting plate 1 is fixedly connected to the top side wall of the municipal bridge, and the guardrail 2 and the buffer guardrail structure 3 form two layers of protection, thereby better increasing the strength of the anti-collision guardrail, thereby ensuring the safety of the vehicle;

[0062] When a vehicle loses control and hits the guardrail, the front of the vehicle first contacts the guardrail vertical plate 301 and the guardrail crossbar 302. The guardrail vertical plate 301 and the guardrail crossbar 302 move toward the guardrail 2 under the action of the vehicle collision, and the buffer spring 303 and the telescopic rod 304 are compressed. The elastic force generated by the compression of the buffer spring 303 and the impact force of the collision offset each other, thereby reducing the impact force transmitted to the guardrail support vertical plate 201 and the guardrail support crossbar 202, reducing the possibility of damage to the guardrail 2, thereby better blocking the vehicle. The blocking block 401 is exposed during the movement of the guardrail vertical plate 301. As the vehicle moves, the wheel will contact the block 401, which blocks the wheel. The side wall of the wheel fits with the arc groove 403 on the block 401. The tire-breaking spike 402 punctures the tire of the vehicle under the pressure of the wheel and the force of rotation. After the tire is punctured, the friction resistance between the wheel and the bridge surface and between the wheel and the block 401 is increased. The increase in friction resistance can slow down the speed of the vehicle, further reduce the impact force of the vehicle, and thus further block the vehicle, which is convenient for better interception of the vehicle and prevents the vehicle from rushing out of the bridge surface and falling.

[0063] Reflector 1 501 is a white reflector that can reflect the lights of vehicles, improve the visibility of vehicles, and increase driving safety. When no accident occurs, reflector 1 501 plays a good warning and auxiliary role. When a collision accident occurs, when guardrail vertical plate 301 moves during the collision, it will drive connecting block 502 to move, and connecting block 502 drives reflector 1 501 to move, so that reflector 1 501 moves away from the front of reflector 2 503. Reflector 2 503 adopts a red reflector. The color of the red reflector is bright and eye-catching. Whether in daytime or night, the driver can notice it from a farther distance, thereby better reminding the driver to avoid accident-free places and avoid secondary accidents.
