Description
Technical Field
[0001] The present application relates to the field of guardrail structures, and in particular to an anti-climbing road guardrail. Background Art
[0002] Road guardrails are generally set up between two-way lanes or between motor vehicle lanes and non-motor vehicle lanes to more fully isolate vehicles of different types and directions, to ensure that vehicles are less likely to violate driving regulations and to improve road safety.
[0003] In order to prevent pedestrians from arbitrarily crossing the road over the guardrail, existing guardrails are equipped with some air cushions, and then a corresponding trigger mechanism is set on the side of the road close to the guardrail. When a pedestrian moves close to the guardrail and applies pressure on the trigger mechanism, the air pump in the guardrail runs to expand the air cushion, thereby preventing pedestrians from climbing over the guardrail. For example, an anti-climbing safety road guardrail with publication number CN112681189A is disclosed.
[0004] With regard to the above-mentioned related technologies, the expansion of the air cushion forces pedestrians to be unable to cross the guardrail, and at the same time, it will make pedestrians stay in the corresponding lane. At this time, if the pedestrians return along the original route, it is easy to cause safety problems. Summary of the invention
[0005] In order to reduce the possibility of pedestrians climbing over the guardrail while also reducing the probability of causing safety problems to pedestrians, the present application provides an anti-climbing road guardrail.
[0006] The present application provides an anti-climbing road guardrail that adopts the following technical solution.
[0007] An anti-climbing road guardrail comprises a guardrail base arranged on a road surface to separate a road, a row of blocking plates being arranged on the upper portion of the guardrail base along its length direction, a row of projecting plates being slidably connected on both sides of the guardrail base in the length direction, an projecting plate electric cylinder being arranged in the guardrail base to switch the projecting plates between two states of being exposed from the guardrail base and being built into the guardrail base, pedestrians can temporarily stay between two adjacent projecting plates, a warning member for warning vehicles is arranged on the side of each row of projecting plates facing the direction of oncoming vehicles in the corresponding lane, and a rear triggering part being arranged on opposite sides of the guardrail base to detect approaching pedestrians so as to operate the projecting plate electric cylinder and the warning member.
[0008] By adopting the above technical solution, when a pedestrian has crossed the lane on one side of the guardrail base to the vicinity of the guardrail base and stepped on the rear trigger part, the overhanging piece will extend. On the one hand, it will provide a certain degree of protection for the pedestrian close to the guardrail base. On the other hand, the warning piece on the overhanging piece can also warn the vehicle driver, so that the vehicle can slow down or stop in time, so that the pedestrian can return to the original route more safely.
[0009] Optionally, the blocking plate is rotatably connected to the guardrail base, and two adjacent blocking plates can be close to each other. A blocking plate motor for driving the blocking plate to rotate is provided in the guardrail base. Front triggering parts are provided on opposite sides of the guardrail base and located near the edge of the lane of the sidewalk. The front triggering parts are stepped on by pedestrians to enable the blocking plate motor to operate and keep the two adjacent blocking plates close to each other.
[0010] By adopting the above technical solution, when a pedestrian wants to cross the lane at the edge of the sidewalk, the pedestrian will step on the front trigger part so that the corresponding blocking piece can be flipped immediately, so that the two adjacent blocking pieces remain close to each other, so as to eliminate the idea of pedestrians forcibly crossing the gap between the two blocking pieces.
[0011] Optionally, the front trigger part includes a base block, a pedal slidably connected to the base block, a pressure sensor arranged in the base block and detecting the pressure applied to the pedal, a return spring arranged in the base block to force the pedal to move upward, and a limit member detachably connected to the pedal and limiting the pedal from being separated from the base block.
[0012] By adopting the above technical solution, when a pedestrian steps on the pedal, the pressure value detected by the pressure sensor increases, so that the external controller can judge whether a pedestrian intends to cross the lane based on this.
[0013] Optionally, the pedal is sleeved on a base block, a bottom frame opening is formed around the bottom of the base block, and a limiting member is slidably connected to an inner wall of the bottom frame opening.
[0014] By adopting the above technical solution, the pedal can be moved and operated more stably.
[0015] Optionally, the bottom of the surface of the bottom frame opening for sliding connection of the limit piece is formed as a pressure inclined surface, the higher the height of the pressure inclined surfaces on both sides, the smaller the distance between the two positions; a slope seal is provided on the surface of the limit piece facing the pressure inclined surface, and a flat seal that can abut against the top surface of the bottom frame opening is provided on the upper surface of the limit piece.
[0016] By adopting the above technical solution, when the pedal is not pressed and moves downward, the flat seal can prevent external water from entering the base block, and when the pedal is pressed and moves downward, the inclined seal is pressurized and the greater the pressure, the better the sealing effect of the inclined seal, so as to minimize the possibility of external water entering the base block.
[0017] Optionally, the rear trigger part and the front trigger part have consistent structures, and a buzzer is provided on the guardrail base; when the pressure value detected by the rear trigger part is within a preset pressure range, the extended plate electric cylinder and the warning part are operated; when the pressure value detected by the rear trigger part exceeds the pressure threshold, the buzzer sounds an alarm.
[0018] By adopting the above technical solution, when the distance between the vehicle and the guardrail base is too close, the wheel will apply greater pressure to the rear trigger part, so that the protruding piece will not extend out of the guardrail base, making it difficult for the protruding piece to touch the vehicle close to the guardrail base, thereby avoiding accidents. At the same time, the buzzer emits a sound of a certain decibel to remind the vehicle driver to adjust the direction in time to maintain a suitable distance between the guardrail base and the vehicle.
[0019] Optionally, display modules are provided on both opposite sides of the blocking piece; when the pressure value detected by the front trigger part exceeds the pressure threshold, the display module on the corresponding blocking piece synchronously displays a warning message for pedestrians; when the pressure value detected by the rear trigger part is within a preset pressure range, the display module located within a predetermined distance in front of the corresponding rear trigger part in accordance with the direction of the oncoming vehicle synchronously displays a warning message for the vehicle driver.
[0020] By adopting the above technical solution, on the one hand, pedestrians are further reminded not to cross the lane, and on the other hand, reminders are given in advance to drivers of vehicles approaching pedestrians near the guardrail base, so that the vehicle drivers can be prepared in advance, further reducing the possibility of accidents.
[0021] Optionally, the angle between the blocking piece corresponding to the display module displaying the warning information for the vehicle driver and the corresponding lane direction is between 120° and 150°.
[0022] By adopting the above technical solution, the angle of the display module can be adjusted to an angle that is easier for the vehicle driver to observe.
[0023] Optionally, the blocking sheet is formed with a plurality of air holes, and the air holes are fixedly connected to a hole blocking net.
[0024] By adopting the above technical solution, the blocking piece can have a certain area while reducing the weight of the blocking piece and the wind load it bears, and the hole blocking net can also prevent pedestrians from climbing through the wind hole.
[0025] Optionally, a distance sensor is provided on the side of the overhanging piece that can expose the guardrail base; when the distance value detected by the distance sensor is less than a distance threshold, the electric cylinder of the overhanging piece stops running.
[0026] By adopting the above technical solution, when a vehicle unexpectedly stops at the guardrail base, if the vehicle driver gets off the vehicle and steps on the rear trigger part, the overhanging piece will extend out of the guardrail base. When the overhanging piece approaches the stopped vehicle, the overhanging piece can stop in time to avoid the overhanging piece causing damage to the vehicle or personnel, thereby reducing the possibility of a secondary accident.
[0027] In summary, the present application includes at least the following beneficial effects.
[0028] When a pedestrian has crossed the lane on one side of the guardrail base to the vicinity of the guardrail base and stepped on the rear trigger part, the overhanging piece will extend. On the one hand, it will provide a certain degree of protection for the pedestrian close to the guardrail base. On the other hand, the warning piece on the overhanging piece can also alert the vehicle driver, so that the vehicle can slow down or stop in time, so that the pedestrian can return to the original route more safely.

DETAILED DESCRIPTION
[0031] The present application is further described in detail below in conjunction with the accompanying drawings.
[0032] The present application embodiment discloses an anti-climbing road guardrail, referring to Figure 1 It includes a guardrail base 1 fixedly connected to the road surface between two opposite lanes. The length direction of the guardrail base 1 is consistent with the length direction of the road. The guardrail base 1 can be set in several sections along the length direction of the road as needed. Several blocking pieces 2 are installed on the upper part of the guardrail base 1 along its own length direction to prevent pedestrians from climbing over the guardrail base 1.
[0033] Reference Figure 2 and Figure 3 Each barrier 2 rotates around its own vertical center line and is connected to the upper part of the guardrail base 1. Two adjacent barrier 2 are close to each other. The guardrail base 1 is equipped with a barrier motor 43 corresponding to each barrier 2. The output shaft of the barrier motor 43 is coaxially detachably connected to the rotation point of the barrier 2. A front trigger 44 is installed at the edge of the sidewalk close to the lane.
[0034] Reference Figure 2 and Figure 3 The front triggering part 44 includes a base block 45 buried in the sidewalk, and a pedal 46 is sleeved and slidably connected to the upper part of the base block 45 in the vertical direction. A pressure sensor 47 is detachably connected to the bottom surface of the base block 45. The pressure sensor 47 and the blocking piece motor 43 are both electrically connected to an external controller. A reset spring 48 is detachably connected between the upper surface of the pressure sensor 47 and the pedal 46, and the reset spring 48 forces the pedal 46 to move upward. At the same time, the surfaces of the two opposite sides of the blocking piece 2 can be detachably connected to a display module 36 electrically connected to an external controller. The blocking piece 2 corresponding to each section of the guardrail base 1 can face the direction of the oncoming vehicle on the lane to display relevant information for the vehicle driver to know. The blocking piece 2 is penetrated by a wind hole 37 to reduce the weight of the blocking piece 2 and the wind load it receives. Each wind hole 37 is fixedly connected to a hole blocking net 38, which can prevent pedestrians from inserting their fingers into the wind hole 37, thereby reducing the possibility of pedestrians climbing the blocking piece 2 with the help of the wind hole 37.
[0035] When a pedestrian comes to the edge of the sidewalk and intends to cross the lane, the pedestrian will step on the pedal 46, so that the pressure value detected by the pressure sensor 47 exceeds the pressure threshold preset in the external controller. At this time, the blocking piece motor 43 operates so that the blocking pieces 2 corresponding to a section of the guardrail base 1 can be close to each other, so that the larger gap between the two adjacent blocking pieces 2 becomes a smaller gap, and the display module 36 displays a preset warning message for pedestrians, such as prohibiting crossing the road, etc., to reduce the possibility of pedestrians continuing to engage in dangerous behavior of crossing the lane.
[0036] Reference Figure 2 and Figure 4 A bottom frame opening 32 with a rectangular horizontal cross-section is formed around the bottom of the base block 45, and a limiter 49 with a rectangular horizontal cross-section is detachably connected to the bottom of the pedal 46. The upper part of the vertical side surface of the limiter 49 close to its own vertical center line is slidably connected to the upper part of the vertical inner wall of the bottom frame opening 32 along the vertical direction. A pressure inclined surface 33 is formed at the bottom of the vertical inner wall of the bottom frame opening 32. The higher the height of the pressure inclined surface 33 relative to the two side surfaces, the smaller the spacing between them. The bottom periphery of the limiting member 49 is also set as an inclined surface with an inclined direction consistent with the pressure inclined surface 33. The limiting member 49 is fixedly connected with an inclined surface seal 34 and a plane seal 35 which can be made of rubber material. The plane seal 35 is located on the upper surface of the limiting member 49 and can abut against the top surface of the bottom frame opening 32. The inclined surface seal 34 is located at the bottom inclined surface of the limiting member 49 and can abut against the pressure inclined surface 33, so that external water is not easy to enter the base block 45 when the pedal 46 is under force or not under force.
[0037] Reference Figure 2 and Figure 3, the two vertical sides of the guardrail base 1 in the length direction are slidably connected with the extension piece 3, the extension piece 3 moves along the width direction of the guardrail base 1, the extension piece 3 can be completely located inside the guardrail base 1 or extend out of the guardrail base 1, and the guardrail base 1 is equipped with an extension piece electric cylinder 4 which can be a rodless electric cylinder corresponding to each extension piece 3, the power rod of the extension piece electric cylinder 4 can be detachably connected to the extension piece 3, and the extension piece electric cylinder 4 is electrically connected to an external controller. The side of the extension piece 3 facing the direction of the oncoming vehicle in the corresponding lane is detachably connected with a warning member 41, which can be an audible and visual alarm and is electrically connected to an external controller, so as to sound an alarm when the extension piece 3 is extended, reminding the vehicle driver that there is a pedestrian at the corresponding extension piece 3.
[0038] Reference Figure 1 and Figure 3 , rear triggering parts 42 are installed on opposite sides of the guardrail base 1. The structure of the rear triggering part 42 is consistent with that of the front triggering part 44. The pressure sensor 47 of the rear triggering part 42 is electrically connected to the external controller. When the pressure value detected by the pressure sensor 47 of a rear triggering part 42 is within the preset pressure range in the external controller, the corresponding blocking piece motor 43 will also operate to keep the two adjacent blocking pieces 2 in a close state to prevent pedestrians from moving between different guardrail bases 1 and trying to pass between the two blocking pieces 2. The extended piece 3 on the side of the guardrail base 1 close to the corresponding rear triggering part 42 is exposed to the guardrail base 1 under the push of the extended piece electric cylinder 4. At the same time, the warning piece 41 of the extended piece 3 exposed to the guardrail base 1 synchronously alarms to remind the vehicle driver.
[0039] At the same time, all the blocking pieces 2 located in front of the guardrail base 1 where the overhanging piece 3 is exposed within a predetermined distance, such as 50m or 100m, in accordance with the direction of the oncoming vehicle are deflected, and the corresponding display module 36 displays warning information for the vehicle driver, such as, there are pedestrians on the side of the guardrail 50m or 100m ahead, please slow down, etc., to warn the vehicle driver in advance. In addition, the angle between the blocking piece 2 corresponding to the display module 36 that displays the warning information for the vehicle driver and the corresponding lane direction is between 120° and 150°, so that the vehicle driver can more clearly know the corresponding warning information.
[0040] Reference Figure 2 and Figure 3 The guardrail base 1 is detachably connected to a buzzer 31 electrically connected to an external controller. When a vehicle is too close to the guardrail base 1, the pressure value detected by the pressure sensor 47 of the rear trigger part 42 exceeds the pressure threshold. At this time, the extension piece electric cylinder 4 will not operate to ensure that when the vehicle is too close to the guardrail base 1, the extension piece 3 will not extend from the guardrail base 1. At the same time, the buzzer 31 will emit an alarm sound of appropriate decibels to remind the driver to adjust the distance between the vehicle and the guardrail base 1 in time.
[0041] Reference Figure 2 and Figure 3 The vertical side surface of one end of each overhanging piece 3 exposed outside the guardrail base 1 is detachably connected to a distance sensor 39. Several distance sensors 39 can be evenly distributed in the vertical direction of the overhanging piece 3. The distance sensors 39 are electrically connected to an external controller. In the process of the overhanging piece 3 extending out of the guardrail base 1, once a distance value detected by a distance sensor 39 is less than a distance threshold preset in the external controller, the overhanging piece electric cylinder 4 stops running, so that when a vehicle has problems and stops near the guardrail base 1 and applies pressure to the rear trigger part 42, the overhanging piece 3 will not maintain the maximum extended length, so as to reduce secondary injuries to the vehicle or vehicle personnel such as the driver who gets off the vehicle to check.
[0042] The implementation principle of an anti-climbing road guardrail in an embodiment of the present application is as follows: when a pedestrian on the sidewalk changes pressure and intends to enter a lane, the pedestrian will step on the pedal 46 of the front trigger portion 44. At this time, the blocking piece 2 of the corresponding section of the guardrail base 1 rotates from a state facing the oncoming vehicle direction to a state facing the sidewalk. On the one hand, the gap between two adjacent blocking pieces 2 becomes minimum. On the other hand, the display module 36 on the rotating blocking piece 2 will display warning information for pedestrians, so as to dispel the idea of pedestrians intending to cross the lane as much as possible.
[0043] When a pedestrian forcibly crosses the lane to the guardrail base 1 regardless of the warning information, the pedestrian will step on the pedal 46 of the rear trigger part 42. At this time, the blocking piece 2 corresponding to the guardrail base 1 will also remain in a state facing the sidewalk, and the corresponding protruding piece 3 of the guardrail base 1 will extend to provide a certain protection for the pedestrian. At the same time, the warning piece 41 on the protruding piece 3 will sound and light alarm to remind the vehicle driver that there is a pedestrian at the corresponding guardrail base 1. At the same time, the blocking piece 2 within a predetermined distance in the direction of the oncoming vehicle at the guardrail base 1 where the pedestrian is located rotates to a suitable angle, and the corresponding display module 36 displays warning information for the vehicle driver to remind the driver that there is a pedestrian near the guardrail base 1 within a certain distance ahead and that the driver needs to slow down in time.
[0044] 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.
