Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic safety facilities, in particular to a highway crash barrier used in traffic safety facility engineering. Background Art
[0002] A highway noise barrier is a facility specially designed to reduce the impact of traffic noise on nearby residential areas, commercial areas or other sensitive areas. It reduces noise transmission by blocking, absorbing or reflecting sound waves, thereby improving the acoustic quality of the surrounding environment.
[0003] Currently, soundproofing walls are typically installed on concrete walls with screws and arranged along the sides of highways to achieve a soundproofing effect. This method of securing the soundproofing walls to the concrete walls allows them to be arranged along both sides of the highway. In the event of an out-of-control vehicle crashing into the road, the concrete walls can prevent the vehicle from running off the road. However, the concrete base is generally very hard and does not provide a good cushioning effect. Therefore, the impact force generated by an out-of-control vehicle colliding with the concrete walls often causes damage to the vehicle and the walls, and in more serious cases, can result in casualties.
[0004] Therefore, the existing method of fixing the sound insulation wall by a concrete wall has the problem that the concrete wall is difficult to act as a good buffer, which may easily cause serious damage to the vehicle and the wall, or even casualties when a vehicle collides with the concrete wall. Utility Model Content
[0005] The purpose of the utility model is to provide a highway crash barrier for traffic safety facility engineering, so as to solve the technical problem in the prior art that the concrete wall is difficult to act as a good buffer, which leads to damage to the vehicle wall and even casualties when colliding with an out-of-control vehicle.

[0010] The buffer plates are arranged in a tile-like overlapping manner along the vertical inner wall of the opening; the first elastic member is arranged at the overlapping portion of each two buffer plates and connects the two buffer plates; the second elastic member is arranged at one end of each buffer plate close to the wall and fixed to the wall;
[0011] When an out-of-control vehicle hits the buffer plate, the buffer plate is impacted and presses down the first elastic member and the second elastic member, and the first elastic member then presses down the next level of the buffer plate at the overlapping position to disperse and absorb the impact energy step by step.
[0012] As a preferred solution of the present invention, the first elastic member includes a first telescopic rod and a first spring, the first telescopic rod is fixedly connected to every two buffer plates, and the first spring is sleeved on the first telescopic rod.
[0013] As a preferred solution of the present invention, the second elastic member includes a second telescopic rod and a second spring, the second telescopic rod is connected and fixed to the wall and the buffer plate, and the second spring is sleeved on the second telescopic rod.
[0014] As a preferred solution of the present invention, the length of the second spring is greater than that of the first spring.
[0015] As a preferred solution of the present invention, multiple groups of buffer rollers are provided on the outer side of the buffer plate, and each group of the buffer rollers has two layers, an upper layer and an lower layer.
[0016] As a preferred solution of the present invention, the wall is provided with buffer layers on both the upper and lower sides of the opening.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] like Figure 1 and 2 As shown, the utility model provides a highway crash barrier for traffic safety facility engineering, comprising:
[0029] The wall 1 is provided on both sides of the road, and a C-shaped opening 11 is provided on the side of the wall 1 facing the road surface;
[0030] The buffer assembly 2 is disposed in the opening 11 and includes a first elastic member 21, a second elastic member 22 and a buffer plate 23;
[0031] The buffer plates 23 are arranged in a tile-like overlapping manner along the vertical inner wall of the opening 11. The first elastic member 21 is provided at the overlapping portion of each two buffer plates 23 and connects the two buffer plates 23. The second elastic member 22 is provided at one end of each buffer plate 23 close to the wall 1 and is fixed to the wall 1.
[0032] When the out-of-control vehicle hits the buffer plate 23, the buffer plate 23 is impacted and presses down its first elastic member 21 and second elastic member 22. The first elastic member 21 then presses down the next level buffer plate 23 at the overlapping position to disperse the impact energy step by step.
[0033] In this embodiment, the buffer plates 23 are arranged in an overlapping manner. When an out-of-control vehicle hits the buffer plate 23, the first elastic member 21 and the second elastic member 22 of the buffer plate 23 can be pressed down, and the first elastic member 21 can press down the next-level buffer plate 23, thereby dispersing the impact force to the first elastic member 21 and the second elastic member 22 of the next-level buffer plate 23. Similarly, when the out-of-control vehicle hits the next buffer plate 23, its impact force can be further dispersed and absorbed.
[0034] In this embodiment, the buffer plates 23 are arranged in an overlapping manner. When an out-of-control vehicle collides with the buffer plate 23 and presses down its first elastic member 21 and second elastic member 22, the first elastic member 21 can press down the next level buffer plate 23, thereby dispersing the impact force generated by the collision to the first elastic member 21 and second elastic member 22 of the next level buffer plate 23, thereby dispersing the impact force downward, and when the out-of-control vehicle collides forward with the next buffer plate 23, the impact force can be dispersed and absorbed in the same way, thereby playing a buffering role in the event of a collision and protecting the safety of people and vehicles.
[0035] In order to enable the first elastic member 21 to connect the two buffer plates 23 and be compressed when subjected to a collision, the following preferred embodiments are proposed.
[0036] like Figure 3 As shown, the first elastic member 21 includes a first telescopic rod 211 and a first spring 212 . The first telescopic rod 211 is fixedly connected to every two buffer plates 23 , and the first spring 212 is sleeved on the first telescopic rod 211 .
[0037] Specifically, every two buffer plates 23 are connected by a first telescopic rod 211 and supported by a first spring 212. When a collision occurs, the buffer plate 23 can press down the first spring 212, and the first telescopic rod 211 retracts at the same time. During this process, the first spring 212 can absorb the impact force caused by the collision.
[0038] In order to enable the second elastic member 22 to connect to the buffer plate 23 to fix it on the wall 1 and press it downward when it is impacted, the following preferred embodiments are proposed.
[0039] like Figure 3 As shown, the second elastic member 22 includes a second telescopic rod 221 and a second spring 222 . The second telescopic rod 221 is connected to the fixed wall 1 and the buffer plate 23 , and the second spring 222 is sleeved on the second telescopic rod 221 .
[0040] Specifically, the second telescopic rod 221 is connected to the buffer plate and fixed on the wall 1, and the second spring 222 is sleeved on the second telescopic rod 221. When impacted, the buffer plate 23 can press down the second spring 222, and the second telescopic rod 221 retracts at the same time. During this process, the second spring 22 can absorb the impact force caused by the collision.
[0041] When an out-of-control vehicle hits the buffer plate 23, the first spring 212 and the second spring 222 of the buffer plate 23 can be compressed in the first time to absorb the impact force. In order to withstand a larger impact force, it is necessary to be able to quickly disperse the pressure to the next-level buffer plate 23 through the first spring 212, and then absorb the impact force through the first spring 212 and the second spring 222 of the next-level buffer plate 23. The following preferred embodiments are proposed.
[0042] like Figure 3 As shown, the length of the second spring 222 is greater than the length of the first spring 212 .
[0043] Specifically, the length of the second spring 22 is greater than that of the first spring 212 , so that the first spring 212 can be compressed to its shortest before the second spring 222 , thereby dissipating the impact force to the next-level buffer plate 23 through the first spring 212 before the second spring 222 reaches its maximum compression value.
[0044] In order to further enhance the buffering effect of the buffer plate 23 and reduce the impact force between the vehicle and the buffer plate 23, the following preferred embodiments are proposed.
[0045] like Figure 1 and 2 As shown, multiple groups of buffer rollers 231 are provided on the outer side of the buffer plate 23 , and each group of the buffer rollers 231 has two layers, an upper layer and a lower layer.
[0046] Specifically, when the out-of-control vehicle collides with the buffer plate 23 , it will come into contact with the buffer roller 231 . The buffer roller 231 rolls under the action of the impact, reducing the friction area while also diluting the impact force.
[0047] The double-layered and multi-group buffer rollers 231 can provide a safety redundancy effect, that is, if a single buffer roller 231 is damaged, the other buffer rollers 231 can still play a buffering role.
[0048] For some vehicles with larger bodies, when the buffer plate is pressed down in a collision, it will collide and rub against the wall. Therefore, the following preferred embodiments are proposed.
[0049] like Figure 1 As shown, the wall 1 is provided with buffer layers 111 on both the upper and lower sides of the outer side of the opening 11 .
[0050] Specifically, when the vehicle body contacts the wall, the buffer layer 111 can reduce the damage.
[0051] In this embodiment, when a collision occurs, the out-of-control vehicle hits the buffer plate 23, and preliminary buffering is performed by the buffer roller 231. At the same time, the buffer plate 23 presses down its first spring 212 and second spring 222. The first spring 212 simultaneously presses down the next-level buffer plate 23, thereby compressing the first spring 212 and second spring 222 of the next-level buffer plate 23, thereby dispersing the pressure downward. Similarly, when the vehicle hits the next buffer plate 23 forward, it can further disperse and absorb the impact force caused by the collision.
[0052] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
