Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway guardrails, in particular to a three-wave plate highway protection structure. Background Technique
[0002] Highway guardrails refer to a kind of protective facilities set on both sides or in the middle of highways. Their main function is to protect the safety of pedestrians and vehicles. On roads with large traffic flows such as highways, vehicles travel at high speeds. Once an accident occurs, the consequences are often very serious. Highway guardrails can effectively isolate vehicles and pedestrians, prevent vehicles from running off the road, and thus protect the safety of pedestrians and vehicles.
[0003] In the prior art, most highway guardrails install the guardrail columns by means of concrete embedding or fixing with bolts to concrete. However, when being impacted, this installation method is very likely to make the guardrail columns form slopes, resulting in vehicles running off the road and affecting rescue. And since the battery packs of existing new energy vehicles are generally at the bottom of the vehicles, when the guardrail columns tilt up, it is very easy to tilt up the concrete blocks, and it is easy to scratch the vehicle floor during the process of the vehicle running out, which is likely to cause problems such as battery damage and fire. Content of the Utility Model
[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a three-wave plate highway protection structure so as to solve the technical problems mentioned in the above background technique.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions:
[0006] A three-wave plate highway protection structure includes an installation base. Guide rails are arranged on both sides of the top of the installation base. Installation holes are formed in the side walls of both guide rails. A support rod is slidably arranged inside the guide rails. A buffer bolt passing through the installation holes is arranged inside the support rod;
[0007] One side top end of the support rod is provided with a guardrail column. A support structure is arranged at the included angle position where the guardrail column is connected to the support rod. A protection mechanism is arranged on the side wall of the guardrail column.
[0008] Furthermore, the support structure includes an inclined rod. The inclined rod is located at the included angle between the guardrail column and the support rod, and the end of the inclined rod is in a right-angled conical shape and is fixedly connected to the side wall of the guardrail column and the top wall of the support rod. The other end of the inclined rod is provided with a support beam. Both ends of the support beam are fixedly connected to the guardrail column and the support rod respectively.
[0009] Further, the protection mechanism includes connecting bolts. A plurality of bolt holes arranged in a linear array are formed at the top end of the side wall of the guardrail column. The connecting bolts are installed inside the bolt holes. One end of the connecting bolts is provided with extension screws, and a three-wave guard plate is sleeved on the outer wall of the extension screws.
[0010] Further, a plurality of arc-shaped bottom plates arranged linearly are provided at the bottom end of the installation base, and the outer arc surfaces of the arc-shaped bottom plates face the three-wave guard plate.
[0011] Further, a plurality of installation holes are provided and arranged linearly. Along the linear direction of the guide rail, the length of the installation holes gradually increases, and the distance between the installation holes also gradually increases.
[0012] Further, when one end of the support rod where the guardrail column is installed contacts the inner end wall of the guide rail, each of the buffer bolts contacts the inner end of the installation hole.
[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:
[0014] 1. For this three-wave plate highway protection structure, when being impacted by a vehicle, since a support structure is provided at the connection between the guardrail column and the support rod, it can effectively support the guardrail column, prevent the guardrail column from forming a slope, thereby reducing the possibility of the vehicle rushing out of the highway for the purpose of facilitating rescue. At the same time, it can effectively prevent the concrete from warping and scratching the car battery or car fuel pipe, and can effectively reduce the risk of vehicle fire or even explosion.
[0015] 2. For this three-wave plate highway protection structure, when the vehicle impacts the guardrail, the impact force of the vehicle will overcome the friction between the buffer bolt and the installation hole. Since the installation hole is strip-shaped and the lengths of the installation holes at different positions are different, when the support rod moves, the three buffer bolts will sequentially impact the hole wall of the installation hole, and the buffer bolt that first impacts the hole wall of the installation hole will break under the influence of the vehicle impact to gradually reduce the impact force of the vehicle, thereby reducing the impact on the passengers in the car.

Specific embodiments
[0022] The following further describes the present utility model in detail with reference to the accompanying drawings.
[0023] Embodiment:
[0024] Refer to Figure 1 - Figure 4 A three-wave plate highway protection structure disclosed by the present utility model includes an installation base 1. Both sides of the top of the installation base 1 are provided with guide rails 2. Installation holes 3 are opened on the side walls of the two guide rails 2. A support rod 4 is slidably arranged inside the guide rail 2. A buffer bolt 5 passing through the installation hole 3 is arranged inside the support rod 4;
[0025] One side top end of the support rod 4 is provided with a guardrail column 6. A support structure 7 is arranged at the included angle position where the guardrail column 6 is connected to the support rod 4. A protection mechanism 8 is arranged on the side wall of the guardrail column 6.
[0026] In this embodiment, during installation, the installation base 1 is fixed on the top of a concrete foundation, and the end wall of the guide rail 2 faces the highway. Then, the support rod 4 is installed inside the guide rail 2, and the end of the support rod 4 provided with the guardrail column 6 is in contact with the end wall of the guide rail 2. At this time, the end of the support rod 4 provided with the guardrail column 6 faces the highway. And after the support rod 4 is installed, the support rod 4 and the guide rail 2 are fixed through the setting of bolts and the installation holes 3 to prevent the support rod 4 from sliding randomly;
[0027] When impacted by a vehicle, since a support structure 7 is provided at the connection between the guardrail post 6 and the support rod 4, it can effectively support the guardrail post 6, prevent the guardrail post 6 from forming a slope, thereby reducing the possibility of the vehicle running off the road for the purpose of facilitating rescue. At the same time, it can effectively prevent the concrete from warping and scratching the car battery or car fuel pipe, and can effectively reduce the risk of the vehicle catching fire or even exploding.
[0028] In a further preferred embodiment of the present invention, as Figures 1-4 shown, the support structure 7 includes an inclined rod 71. The inclined rod 71 is located at the included angle between the guardrail post 6 and the support rod 4, and the end of the inclined rod 71 is in a right-angled conical shape and is fixedly connected to the side wall of the guardrail post 6 and the top wall of the support rod 4. A support beam 72 is provided at the other end of the inclined rod 71, and both ends of the support beam 72 are fixedly connected to the guardrail post 6 and the support rod 4 respectively.
[0029] In this embodiment, the inclined rod 71 and the support beam 72 jointly form a T-shaped support structure 7 to support the support rod 4 and the guardrail post 6, so that the possibility of the guardrail post 6 tilting after being impacted can be effectively reduced, and it can effectively prevent the guardrail post 6 from forming a slope, which is likely to cause the vehicle to run off the road, and can effectively improve the convenience of rescue in case of an accident.
[0030] In a further preferred embodiment of the present invention, as Figures 1-4 shown, the protection mechanism 8 includes a connecting bolt 81. A plurality of bolt holes 61 arranged in a linear array are opened at the top end of the side wall of the guardrail post 6. The connecting bolt 81 is installed inside the bolt hole 61, and an extension screw 82 is provided at one end of the connecting bolt 81. A three-wave guard plate 83 is sleeved on the outer wall of the extension screw 82.
[0031] In this embodiment, the three-wave guard plate 83 is wavy, and there is good anti-bending property between the wave crests and wave troughs of the corrugated guardrail, which can effectively improve the strength of the guardrail plate. And the corrugated design enables the guardrail plate to disperse the collision force through its special shape when the vehicle collides, reducing the harm to the vehicle and the occupants.
[0032] In a further preferred embodiment of the present invention, as Figures 1-4 shown, a plurality of arc-shaped bottom plates 9 arranged in a linear pattern are provided at the bottom end of the mounting base 1, and the outer arc surface of the arc-shaped bottom plate 9 faces the three-wave guard plate 83.
[0033] In this embodiment, when the concrete base is not completely hardened, the arc-shaped bottom plate 9 is inserted into the concrete base. When the concrete base is completely hardened, the purpose of effectively fixing the mounting base 1 can be achieved.
[0034] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, a plurality of mounting holes 3 are provided and arranged linearly. Along the linear direction of the guide rail 2, the length of the mounting holes 3 gradually increases, and the spacing between the mounting holes 3 also gradually increases.
[0035] In this embodiment, three groups of mounting holes 3 are provided, and the number of buffer bolts 5 is equal to that of the mounting holes 3. When the vehicle impacts the guardrail, the impact force of the vehicle will overcome the frictional force between the buffer bolts 5 and the mounting holes 3. Since the mounting holes 3 are strip-shaped and the lengths of the mounting holes 3 at different positions are different, when the support rod 4 moves, the three groups of buffer bolts 5 will sequentially impact the inner walls of the mounting holes 3, and the buffer bolt 5 that first impacts the inner wall of the mounting hole 3 will break under the influence of the vehicle impact, so as to gradually reduce the impact force of the vehicle and thus reduce the impact on the passengers in the vehicle.
[0036] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, when one end of the support rod 4 where the guardrail post 6 is installed contacts the inner end wall of the guide rail 2, each of the buffer bolts 5 contacts the inner end of the mounting hole 3.
[0037] In this embodiment, when one end of the support rod 4 contacts the inner end wall of the guide rail 2, each of the buffer bolts 5 contacts the inner end of the mounting hole 3. Therefore, when the support rod 4 moves, the purpose of making the three groups of buffer bolts 5 contact the mounting holes 3 at different moving distances can be achieved.
[0038] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
