Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrail equipment, in particular to a three-wave anti-collision guardrail plate. Background Technique

[0002] The continuous construction and operation of expressways have greatly facilitated the travel of the masses and the economic development of all regions along the way. The guardrail is the last barrier for highway traffic safety. When the anti-collision performance of the guardrail does not meet the requirements, after the vehicle hits the guardrail, it will rush out of the road or cross the median strip, resulting in serious casualties and property losses.

[0003] Chinese Patent Publication No. CN215629626U discloses a three-wave anti-collision guardrail plate, including a main board. Side plates are arranged on both sides of the main board. A plurality of groups of movable rods A are sleeved at the middle position of the bottom of the main board. Impact blocks B are arranged at the bottoms of the plurality of groups of movable rods A. A plurality of groups of movable rods B are sleeved at the middle positions of the tops of the two side plates. Impact blocks A are arranged at the tops of the plurality of groups of movable rods B. Springs A are sleeved on the outer sides of the movable rods A and the movable rods B. Through the mutual cooperation among the movable rod A, the impact block A, the spring A, the rotating plate, the impact block B, the spring B, the movable plate A, the movable rod B, the push plate, the movable plate B and the spring C, when the device is impacted, the push plate can drive the push plate to apply force to the impact object in the direction opposite to the impact direction to offset a certain impact force, and at the same time, part of the impact force received by the device can be dispersed and converted to reduce the impact strength received by the device.

[0004] In the above patent, it has good protection for vertically impacting vehicles. However, when an accident occurs, the impact between the vehicle and the guardrail is mostly inclined. When the impact direction between the vehicle and the guardrail is inclined, the thrust applied by the above-mentioned push plate to the impact object is perpendicular to the straight line direction of the guard plate. Therefore, it is easy to cause the vehicle to lose control again, which will affect the other vehicles on the expressway and is also easy to cause secondary injuries to the passengers. Content of the Utility Model

[0005] In view of the deficiencies of the existing technology, the purpose of the present utility model is to provide a three-wave anti-collision guardrail plate to solve the technical problems mentioned in the above background technique.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A three-wave anti-collision guardrail plate includes a support guard plate. A support structure is arranged on one side of the support guard plate. An energy-absorbing guard plate is slidably arranged on the outer side wall of the support guard plate.

[0008] The support guard plate is in a triple-wave shape. Positioning plates for installing the support structure are provided on both sides of the support guard plate. Two groups of sliding grooves are formed inside the support guard plate, and two groups of sliding members are arranged inside each sliding groove;

[0009] The energy-absorbing guard plate is in a triple-wave shape, and the wave crests and wave troughs correspond to those of the support guard plate. The energy-absorbing guard plate is slidably connected to the support guard plate through the sliding members. A support protrusion is provided in the middle of the support guard plate, and an energy-absorbing protrusion is provided in the middle of the energy-absorbing guard plate.

[0010] Further, the sliding member includes a connecting sleeve. The connecting sleeve is fixedly connected to the side wall of the energy-absorbing guard plate and is inserted into the sliding groove. An extension rod is connected inside the connecting sleeve through a spring, and a limiting disk is provided at one end of the extension rod extending out of the connecting sleeve.

[0011] Further, the support structure includes two columns and two support rods. The two columns are respectively fixedly connected to the two positioning plates. An installation rod is commonly connected to the tops of the opposite sides of the two columns, and the two support rods are fixedly arranged at both ends of the installation rod.

[0012] Further, the inside of the energy-absorbing guard plate is hollow, and shock-absorbing rubber is provided inside the energy-absorbing guard plate. The wave crests and wave troughs of the energy-absorbing guard plate correspond to those of the support guard plate.

[0013] Further, both the energy-absorbing protrusion and the support protrusion are arc-shaped, and the positions of the support protrusion and the energy-absorbing protrusion correspond to each other.

[0014] Further, when the two ends of the energy-absorbing guard plate are aligned with the two ends of the support guard plate, all positions of the connection surface between the energy-absorbing guard plate and the support guard plate are in contact with each other.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] 1. For this triple-wave anti-collision guardrail plate, when an accident occurs, the vehicle impacts the energy-absorbing guard plate at an angle. Since the middle of the energy-absorbing guard plate has an energy-absorbing protrusion, during the impact and sliding process of the vehicle, it will push the energy-absorbing guard plate to slide, and thus buffer the impact force of the vehicle through the resistance during the sliding of the energy-absorbing guard plate, achieving the purpose of reducing the impact force of the vehicle to protect passengers;

[0017] 2. When a vehicle collides with the guard plate, the contact surface between the vehicle and the guard plate is affected by the energy-absorbing convex part, which will push the energy-absorbing convex part to slide. Since the support guard plate has a support convex part, a deflecting thrust will be generated when the vehicle pushes the energy-absorbing convex part, guiding the deflecting direction of the vehicle and causing a slight offset at the impact point. And because both the energy-absorbing convex part and the support convex part are arc-shaped, it can effectively adjust the angle between the vehicle's traveling direction and the guardrail, thereby reducing the force generated during the collision between the vehicle and the guardrail, and further achieving the purpose of reducing accident damage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will further elaborate on the present invention with reference to the accompanying drawings.

[0025] Embodiment:

[0026] Refer to Figure 1 - Figure 4 , a three-wave anti-collision guardrail plate disclosed by the present invention includes a support guard plate 1, a support structure 2 is arranged on one side of the support guard plate 1, and an energy-absorbing guard plate 3 is slidably arranged on the outer side wall of the support guard plate 1;

[0027] The support guard plate 1 is in a triple-wave shape. Positioning plates 4 for installing the support structure 2 are arranged on both sides of the support guard plate 1. Two sets of sliding grooves 5 are formed inside the support guard plate 1, and two sets of sliding members 6 are arranged inside each of the sliding grooves 5;

[0028] The energy-absorbing guard plate 3 is in a triple-wave shape, and the wave crests and wave troughs correspond to those of the support guard plate 1. The energy-absorbing guard plate 3 is slidably connected to the support guard plate 1 through the sliding members 6. A support protrusion 7 is arranged in the middle of the support guard plate 1, and an energy-absorbing protrusion 8 is arranged in the middle of the energy-absorbing guard plate 3.

[0029] In this embodiment, during use, the support guard plate 1 is installed on the side of the road through the support structure 2, and the side of the support guard plate 1 with the energy-absorbing guard plate 3 installed faces the road. Through the arrangement of the sliding grooves 5 and the sliding members 6, the energy-absorbing guard plate 3 is slidably connected to the support guard plate 1. When an accident occurs, the vehicle impacts the energy-absorbing guard plate 3, and the impact force of the vehicle is buffered through the sliding of the energy-absorbing guard plate 3, so as to reduce the impact force of the vehicle and protect the passengers. Moreover, the impact force of the vehicle is absorbed by the resistance during the sliding of the energy-absorbing guard plate 3, thereby achieving the purpose of reducing accident damage;

[0030] Specifically, when an accident occurs to the vehicle, since the traveling direction of the vehicle is mostly parallel to the straight line direction of the guard plate, when an accident occurs, the traveling direction of the vehicle forms an intersection with the straight line direction of the guard plate. When the vehicle impacts the guard plate, the contact surface between the vehicle and the guard plate is affected by the energy-absorbing protrusion 8 and will push the energy-absorbing protrusion 8 to slide. Since the support guard plate 1 has the support protrusion 7, a deflecting thrust will be generated when the vehicle pushes the energy-absorbing protrusion 8, guiding the deflecting direction of the vehicle and causing a slight offset at the impact point. And since both the energy-absorbing protrusion 8 and the support protrusion 7 are arc-shaped, the included angle between the traveling direction of the vehicle and the guardrail can be effectively adjusted, thereby reducing the acting force generated when the vehicle impacts the guardrail and achieving the purpose of protecting the passengers. Moreover, during the sliding process of the energy-absorbing guard plate 3, it will be resisted by the support protrusion 7, increasing the resistance during the sliding of the energy-absorbing guard plate 3, thereby further reducing the impact force of the vehicle.

[0031] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the sliding member 6 includes a connecting sleeve 61. The connecting sleeve 61 is fixedly connected to the side wall of the energy-absorbing guard plate 3 and is inserted into the sliding groove 5. An extension rod 62 is connected to the inside of the connecting sleeve 61 through a spring, and a limiting disc 63 is arranged at one end of the extension rod 62 extending out of the connecting sleeve 61.

[0032] In this embodiment, through the setting of the connecting sleeve 61, it is used to correspondingly adjust the positions of the energy-absorbing guard plate 3 and the support guard plate 1. Through the setting of the extension rod 62 and the limit disc 63 connected by a spring, it is used to pull the energy-absorbing guard plate 3 to make it fit with the support guard plate 1, so as to buffer the vehicle when an accident occurs.

[0033] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the support structure 2 includes two columns 21 and two support rods 22. The two columns 21 are respectively fixedly connected to the two positioning plates 4. The tops of the opposite sides of the two columns 21 are jointly connected with a mounting rod 23. The two support rods 22 are fixedly arranged at both ends of the mounting rod 23.

[0034] In this embodiment, the positioning plate 4 is used to install the column 21, and then the column 21 cooperates with the mounting rod 23 to install the support rod 22. Furthermore, the column 21 and the support rod 22 are used to fix the support guard plate 1.

[0035] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the inside of the energy-absorbing guard plate 3 is hollow, and shock-absorbing rubber is arranged inside the energy-absorbing guard plate 3. The wave crests and wave troughs of the energy-absorbing guard plate 3 correspond to the wave crests and wave troughs of the support guard plate 1.

[0036] In this embodiment, through the setting of the shock-absorbing rubber, the impact force of the vehicle on the energy-absorbing guard plate 3 is further reduced, achieving the effect of protecting the vehicle.

[0037] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, both the energy-absorbing convex part 8 and the support convex part 7 are arc-shaped, and the positions of the support convex part 7 and the energy-absorbing convex part 8 correspond to each other.

[0038] In this embodiment, since the positions of the support convex part 7 and the energy-absorbing convex part 8 correspond to each other, the support convex part 7 can effectively provide a large resistance to the energy-absorbing guard plate 3. And when the support convex part 7 jacks up the energy-absorbing guard plate 3, the spring inside the connecting sleeve 61 will be stretched to increase the friction force between the energy-absorbing guard plate 3 and the support guard plate 1, achieving the effect of increasing the sliding resistance of the energy-absorbing guard plate 3.

[0039] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, when the two ends of the energy-absorbing guard plate 3 are aligned with the two ends of the support guard plate 1, all positions of the connection surface between the energy-absorbing guard plate 3 and the support guard plate 1 are in contact with each other.

[0040] In this embodiment, when the two ends of the energy-absorbing guard plate 3 are aligned with the two ends of the support guard plate 1, all positions of the connection surface between the energy-absorbing guard plate 3 and the support guard plate 1 are in contact with each other, so that the resistance to the sliding of the energy-absorbing guard plate 3 can be further increased.

[0041] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
