Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a mountain highway guardrail. Background Art

[0002] In recent years, more and more mountain roads have been built. When vehicles are driving on mountain roads, due to the large number of winding mountain roads, narrow roads, limited driving sight distance, and the vehicles are prone to speeding, and at the same time, there is a lot of rain and snow, which makes the road surface slippery and the braking effect is not good. Therefore, it is very easy for cars to have traffic accidents on mountain roads, which can damage the car and cause traffic jams at the least, or even cause the car to be destroyed and people to be injured.

[0003] In the prior art, the guardrails on mountain roads mainly include rigid concrete guardrails, semi-rigid corrugated guardrails, and flexible cable guardrails. Since the concrete guardrail is a rigid structure with low deformation capacity and basically does not absorb energy, the car is easily deformed under the impact of the car, causing casualties to the car and people. In the semi-rigid corrugated guardrail, since the corrugated guardrail itself has little deformation, it basically has no buffering capacity. Under the impact of the car, the corrugated plate is easy to break, causing the car to rush into the opposite lane or fall, and the broken corrugated guardrail is very easy to pierce the car, increasing casualties. The traditional flexible cable guardrail has a small interception effect due to the limited energy absorption of the cable. Although the improved flexible cable guardrail is equipped with a spring buffer, it is easy to cause the vehicle to rebound after interception, which will cause secondary damage to subsequent vehicles and personnel. Summary of the invention

[0004] Based on this, it is necessary to provide a mountain highway guardrail that can effectively improve the protection effect of out-of-control vehicles and reduce vehicle and personnel casualties.

This mountain highway guardrail can absorb the impact force of out-of-control vehicles, improve the protection effect of out-of-control vehicles, and help avoid car rollover and falling accidents or ejection of vehicles endangering the road, reduce vehicle and personnel casualties, and thus improve the safety of driving on mountain roads.

[0030] In one embodiment, see Figure 1 and Figure 2 A mountain highway guardrail 100 includes: a support frame 110, a guardrail net 120 and an energy dissipation component 130. There are at least two support frames 110, and at least two support frames 110 are arranged in parallel and spaced apart. The energy dissipation component 130 includes a first connecting line 131 and an energy dissipation component 132. The first connecting line 131 is connected between two adjacent support frames 110, and the guardrail net 120 is located between two adjacent support frames 110 and connected to the first connecting line 131. The energy dissipation component 132 is arranged on the first connecting line 131 and is used to dissipate the tension of the first connecting line 131.

[0031] During the installation of the mountain highway guardrail 100, first, two support frames 110 are installed at the protection position of the mountain highway; then, the two ends of the guardrail net 120 are connected to the two support frames 110, so that the guardrail net 120 is opened; finally, the first connecting line 131 is connected to the guardrail net 120, and after being tightened, the two ends of the first connecting line 131 are connected to the energy dissipation part 132. During use, when a vehicle loses control and hits the mountain highway guardrail 100, first, the car contacts the guardrail net 120; then, under the further impact of the car, the guardrail net 120 begins to deform greatly, and due to the support of the support frame 110, the guardrail net 120 gradually tightens; then, as the guardrail net 120 continues to tighten, the tension of the first connecting line 131 increases, and the energy dissipation part 132 starts to consume energy and dissipate the tension of the first connecting line 131; finally, the energy is exhausted, and the car is stopped and wrapped in the guardrail net 120. The mountain highway guardrail 100 can absorb the impact force of an out-of-control vehicle, improve the protection effect on the out-of-control vehicle, help prevent the car from rolling over and falling or bouncing off and endangering vehicles on the road, reduce vehicle and personnel casualties, and thus improve the safety of driving on mountain roads.

[0032] Optionally, there are multiple ways to arrange the energy dissipation part 132 and the first connecting wire 131 on the support frame 110. The first way is that there are two first connecting wires 131, and the two ends of the energy dissipation part 132 are respectively connected to the two first connecting wires 131, and the two first connecting wires 131 are connected between the two support frames 110, and the guardrail net 120 is arranged on the first connecting wire 131. Another way is that there is one first connecting wire 131, and one end of the first connecting wire 131 bypasses the two support frames 110, and the opposite ends of the first connecting wire 131 are respectively connected to the opposite ends of the energy dissipation part 132.

[0033] Specifically, see Figure 1 and Figure 2 , the first connecting line 131 surrounds and connects to two adjacent support frames 110 respectively. The opposite ends of the first connecting line 131 are respectively connected to the opposite ends of the energy absorbing component 132. In this way, it is beneficial to improve the installation convenience of the energy absorbing component 130, reduce the connection position, and help prevent the first connecting line 131 from falling off, thereby improving the energy absorbing effect of the energy absorbing component 132 and improving the overall protection effect of the mountain highway guardrail 100. This embodiment only provides a setting method of the first connecting line 131, but is not limited to this.

[0034] Optionally, the first connecting line 131 may be a steel wire rope, a nylon rope, a carbon fiber rope, a metal chain or other connecting devices.

[0035] Specifically, see Figure 1 and Figure 2, the first connecting line 131 is a steel wire rope. In this way, the steel wire rope has a large breaking tensile force, is wear-resistant and high-temperature-resistant, and can transmit long-distance loads, which is conducive to improving the connection stability between the first connecting line 131 and the guardrail net 120 and the structural stability of the energy-consuming component 130, avoiding the first connecting line 131 from being broken by impact, and extending the service life of the first connecting line 131; at the same time, the steel wire rope has good flexibility and is flexible to use, which is conducive to improving the overall quality of the mountain highway guardrail 100. This embodiment only provides a specific implementation of the first connecting line 131, but is not limited to this.

[0036] This embodiment does not specifically limit the structure and type of the energy dissipation part 132, and it only needs to meet the energy dissipation effect. For example, the energy dissipation part 132 is a plate-type energy dissipator, a rod-type energy dissipator, a damper, a liquid viscosity energy dissipator, a friction energy dissipator, a metal deformation energy dissipator, etc. Since the structure of the energy dissipation part 132 is not the object to be improved in this embodiment, its specific structure is not described in detail here, and the existing products and existing literature can be directly referred to.

[0037] In one embodiment, see Figure 1 and Figure 2 The guardrail net 120 includes a net body 121 and a connecting ring 122. The net body 121 is connected to the support frame 110 through the connecting ring 122, and one end of the first connecting line 131 is connected to the energy absorbing part 132, and the other end of the first connecting line 131 passes through the connecting ring 122 and is connected to the energy absorbing part 132. In this way, the setting of the connecting ring 122 is conducive to improving the installation convenience of the guardrail net 120 and the connection stability of the guardrail net 120 and the support frame 110, avoiding the direct connection between the guardrail net 120 and the support frame 110, which makes the guardrail net 120 easy to break, thereby improving the overall quality of the mountain highway guardrail 100.

[0038] For further information, see Figure 1 and Figure 2, there are more than two connecting rings 122. The more than two connecting rings 122 are at least divided into a first connecting ring 1221 and a second connecting ring 1222. The more than two first connecting rings 1221 are arranged at intervals along the height direction of the support frame 110, and the net body 121 is connected to the support frame 110 through the first connecting rings 1221. The more than two second connecting rings 1222 are sleeved on the first connecting line 131. In this way, the second connecting ring 1222 is sleeved on the first connecting line 131, and the first connecting line 131 is in a taut state, so that the net body 121 can be subjected to the tension in the height direction of the support frame 110, thereby opening; the first connecting ring 1221 is connected to the support frames 110 at both ends, so that the net body 121 can be subjected to the tension in the length direction of the support frame 110, thereby causing the net body 121 to open and form a mesh structure, which is conducive to improving the installation convenience of the net body 121, while ensuring that the net body 121 forms a flexible mesh structure, thereby improving the protective effect of the mountain highway guardrail 100, and further improving the overall quality and protective effect of the mountain highway guardrail 100.

[0039] In order to further understand and illustrate the height direction of the support frame 110, Figure 1 For example, the height direction of the support frame 110 is Figure 1 The direction indicated by any arrow on the center line S1.

[0040] Optionally, the net body 121 may be a nylon net, a steel net, a polymer flexible material or other net structures.

[0041] Specifically, see Figure 1 and Figure 2 The net body 121 includes more than two ring mesh pieces 1211, and the more than two ring mesh pieces 1211 are mutually nested to form the net body 121. In this way, on the one hand, the mutually nested ring mesh pieces 1211 can rotate flexibly and form flexibility, which is conducive to avoiding continuous force on the connection, dispersing stress, improving the connection stability of the ring mesh pieces 1211 and the structural stability of the net body 121, extending the service life of the net body 121, and reducing the probability of damage to the net body 121, thereby improving the protective effect of the mountain highway guardrail 100. On the other hand, the mutually nested ring mesh pieces 1211 are easy to install and easy to replace, which is conducive to reducing maintenance costs, thereby improving the overall quality and user experience of the mountain highway guardrail 100. This embodiment only provides a specific implementation method of a net body 121, but is not limited to this.

[0042] Optionally, the ring mesh 1211 may be made of metal, plastic, polymer, carbon fiber or other materials, or the ring mesh 1211 may be made of a combination of multiple materials.

[0043] Specifically, see Figure 1 and Figure 2 , the ring mesh is made of steel. In this way, the structure is stable, rigid, and not easily deformed, which is conducive to improving the connection stability of the ring mesh 1211 and the structural stability of the mesh body 121, extending the service life of the mesh body 121, reducing the probability of damage to the mesh body 121, and thus improving the protective effect of the mountain highway guardrail 100. This embodiment only provides a material selection for a ring mesh 1211, but is not limited thereto.

[0044] Furthermore, a reflective layer (not shown in the figure) is provided on the ring mesh 1211, and the reflective layer is wrapped on the ring mesh 1211. In this way, on the one hand, the reflective layer on the ring mesh 1211 is conducive to warning vehicles traveling on mountain roads, which is conducive to focusing the driver's attention, reducing the risk of accidents, and improving the safety of driving on mountain roads. On the other hand, when the ring mesh 1211 is made of metal material, the reflective layer wrapped on the ring mesh 1211 is conducive to improving the corrosion resistance of the ring mesh 1211, extending the service life of the guardrail net 120, and improving the reliability of the guardrail net 120, thereby improving the overall quality and user experience of the mountain road guardrail 100.

[0045] In one embodiment, see Figure 1 and Figure 2 The support frame 110 includes a support rod 111, a front short column 112 and a second connection line 113. At least two front short columns 112 are arranged at both ends of the support rod 111 along the height direction of the support rod 111, the second connection line 113 connects the two front short columns 112, and the first connection ring 1221 is sleeved on the second connection line 113. In this way, the second connection line 113 on the two support rods 111 provides support for the first connection ring 1221, and the first connection ring 1221 is connected to the net body 121, so that the net body 121 can be unfolded and tensioned along the length direction of the net body 121, so that the net body 121 forms a flexible mesh structure; at the same time, the front short column 112 is conducive to providing support for the first connection line 131, improving the use effect of the energy consumption component 130, and thus improving the protection effect of the mountain highway guardrail 100. After the net body 121 cooperates with the energy consumption component 130, it can avoid vehicle rebound, which is conducive to reducing the occurrence of casualties.

[0046] It should be noted that the height direction of the support rod 111 is the same as the height direction of the support frame 110. Figure 1 The direction indicated by any arrow on the center line S1.

[0047] Optionally, the first connecting line 131 may be a steel wire rope, a nylon rope, a rubber rope, a carbon fiber rope, a metal chain or other connecting devices.

[0048] Specifically, see Figure 1 and Figure 2, the first connecting line 131 is an elastic rubber rope. In this way, the elastic steel wire rope has strong reliability and large elasticity, which is conducive to promoting the deformation of the guardrail net 120, thereby dispersing part of the impact force borne by the energy-absorbing component 132, reducing the destructive effect of the guardrail net 120 on the vehicle, ensuring the protective effect of the guardrail net 120, and improving the overall quality of the mountain highway guardrail 100. This embodiment only provides a specific implementation of the first connecting line 131, but is not limited thereto.

[0049] For further information, see Figure 2 At least two front short posts 112 are provided with steel earrings 1121 arranged opposite to each other. The second connecting line 113 is connected to the two front short posts 112 through the steel earrings. In this way, it is beneficial to improve the connection stability between the second connecting line 113 and the front short posts 112, thereby improving the structural stability of the support frame 110, improving the structural strength of the support frame 110, reducing or even avoiding the occurrence of falling off due to excessive tension of the second connecting line 113, and improving the overall quality of the mountain highway guardrail 100.

[0050] Optionally, the steel earring 1121 and the front short column 112 may be connected by welding, threaded connection, bolt connection, riveting, bonding, plug-in or other connection methods.

[0051] Specifically, see Figure 1 and Figure 2 , the connection method of the steel earring 1121 and the front short column 112 is welding. In this way, it is beneficial to disperse the stress at the connection between the steel earring 1121 and the front short column 112, improve the connection stability of the steel earring 1121 and the front short column 112 and the overall structural stability of the support frame 110, and improve the overall quality and user experience of the mountain highway guardrail 100. This embodiment only provides a specific connection method between the steel earring 1121 and the front short column 112, but is not limited to this.

[0052] In one embodiment, see Figure 1 and Figure 2 , an arc plate 1122 and a limit pin 1123 are provided on the front short column 112. The two arc plates 1122 are arranged opposite to each other and form a gap, and the limit pin 1123 connects the two arc plates 1122. In this way, the first connecting line 131 is passed through the two arc plates 1122, which is conducive to guiding the sliding of the first connecting line 131; the limit pin 1123 can limit the first connecting line 131, which is conducive to improving the reliability of the energy consumption component 130 and improving the use effect and practicality of the mountain highway guardrail 100.

[0053] In one embodiment, see Figure 1 and Figure 2The support frame 110 further includes a rear short column 114. The rear short column 114 and the front short column 112 are arranged on both sides of the support rod 111, and the first connecting line 131 passes through the second connecting ring 1222, the front short column 112 and the rear short column 114, and is connected to the energy dissipation component 132. In this way, through the supporting effect of the front short column 112 and the rear short column 114, it is helpful to improve the supporting effect of the support frame 110 on the guardrail net 120 and the energy dissipation component 130, avoid the deformation of the support rod 111 caused by excessive tension of the first connecting line 131, improve the structural stability of the support frame 110, and further improve the overall quality and user experience of the mountain highway guardrail 100.

[0054] For further information, see Figure 1 and Figure 2 , there are at least two rear short posts 114. The two rear short posts 114 are spaced apart at both ends of the support rod 111 along the height direction of the support rod 111. In this way, the structural stability of the support rod 111 is further improved, and the support rod 111 is prevented from tilting to one side; at the same time, the first connecting line 131 is prevented from being deformed due to excessive tension, thereby improving the overall quality and user experience of the mountain highway guardrail 100.

[0055] For further information, see Figure 1 and Figure 2 , an arc plate 1122 and a limit pin 1123 are provided on the rear short column 114. The two arc plates 1122 are arranged opposite to each other and form a gap, and the limit pin 1123 connects the two arc plates 1122. In this way, the first connecting line 131 is passed through the two arc plates 1122, which is conducive to guiding the sliding of the first connecting line 131; the limit pin 1123 can limit the first connecting line 131, which is conducive to improving the reliability of the energy consumption component 130 and improving the use effect and practicality of the mountain highway guardrail 100.

[0056] In one embodiment, see Figure 1 and Figure 2 The support frame 110 further includes a side short column 115. The side short column 115 is connected to the support rod 111, and the side short column 115 is arranged between the front short column 112 and the rear short column 114 along the circumference of the support rod 111. In this way, it is beneficial to further improve the structural stability of the support rod 111, and at the same time improve the supporting effect of the support frame 110 on the guardrail net 120 and the energy dissipation component 130, avoid the deformation of the support rod 111 caused by excessive tension of the first connecting line 131, and thus improve the overall quality and user experience of the mountain highway guardrail 100.

[0057] For further information, see Figure 1 and Figure 2, an arc plate 1122 and a limit pin 1123 are provided on the side short column 115. The two arc plates 1122 are arranged opposite to each other and form a gap, and the limit pin 1123 connects the two arc plates 1122. In this way, the first connecting line 131 is passed through the two arc plates 1122, which is conducive to guiding the sliding of the first connecting line 131; the limit pin 1123 can limit the first connecting line 131, which is conducive to improving the reliability of the energy consumption component 130 and improving the use effect and practicality of the mountain highway guardrail 100.

[0058] For further information, see Figure 1 and Figure 2 , there are at least two side short posts 115. The two side short posts 115 are spaced apart at both ends of the support rod 111 along the height direction of the support rod 111. In this way, the structural stability of the support rod 111 is further improved, and the support rod 111 is prevented from tilting to one side; at the same time, the first connecting line 131 is prevented from being deformed due to excessive tension, thereby improving the overall quality and user experience of the mountain highway guardrail 100.

[0059] In one embodiment, see Figure 1 and Figure 2 The support frame 110 further includes a base bottom plate 116. The support rod 111, the side short column 115, the front short column 112, and the rear short column 114 are all connected to the base bottom plate 116.
