Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a road traffic safety guardrail. Background Art

[0002] Highway traffic safety refers to the state in which personal injury or property loss can be controlled to an acceptable level during traffic activities. In order to warn and protect oncoming vehicles, corresponding safety protection devices must be designed. Therefore, in order to minimize the scope of impact in the event of an accident, safety guardrails are often installed in the middle of urban highways, between motor vehicle lanes and non-motor vehicle lanes, or on both sides of rural roads.

[0003] With the continuous increase in the number of cars, traffic accidents have become more frequent. Once an accident occurs on a highway with high speeds, it often causes unbearable damage. This prompts us to find ways to minimize the damage caused by highway accidents, so higher performance requirements are placed on highway safety guardrails. Utility Model Content

[0004] In order to solve the problems raised in the above background technology. The utility model provides a highway traffic safety guardrail, comprising a pair of fixed brackets, and a sliding rod arranged between the two fixed brackets, wherein the left and right ends of the sliding rod are respectively sleeved with a left support plate and a right support plate, the left and right support plates are matched with the sliding rod, and the left and right support plates slide left and right on the sliding rod, the sliding rods at the outer ends of the left and right support plates are each provided with a second buffer mechanism, and the sliding rod between the left and right support plates is provided with a plurality of first buffer mechanisms in an array.

[0005] As a highway traffic safety guardrail of the utility model, preferably, the second buffer mechanism includes a sleeve fixed on the left support plate, and a first spring sleeved on the slide rod.

[0006] As a highway traffic safety guardrail of the utility model, preferably, the sleeve matches the first spring, and the sleeve is sleeved around the outer periphery of the first spring.

[0007] As a highway traffic safety guardrail of the utility model, preferably, the first buffer mechanism includes a front reinforcing rib and a rear reinforcing rib fixed between the left support plate and the right support plate, and a limiting ring sleeved on the slide rod.

[0008] As a highway traffic safety guardrail of the utility model, preferably, the limiting ring matches the slide bar, and the limiting ring slides left and right on the slide bar, and the front and rear side walls of the limiting ring respectively fix the front support bar and the rear support bar.

[0009] As a highway traffic safety guardrail of the present invention, preferably, the bottom ends of the front support rod and the rear support rod are connected by a connecting plate, the side wall of the rear support rod is fixedly provided with a U-shaped bracket, and the U-shaped bracket is movably provided with a roller through a bearing.

[0010] As a highway traffic safety guardrail of the utility model, preferably, a second spring is sleeved on the sliding rod between the plurality of limiting rings.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When an out-of-control vehicle hits the roller, since the roller is movably arranged on the U-shaped bracket, the rotation of the roller causes the out-of-control vehicle to change direction, preventing the vehicle from rushing out of the guardrail. At this time, the force of the vehicle impact pushes the limit ring to slide outward on the slide bar through the front support rod and the rear support rod, and is buffered by the second spring. At the same time, when the left support plate or the right support plate receives external force, the left support plate pushes the sleeve outward on the slide bar, and the first spring performs further buffering, absorbing energy step by step. Another significant advantage of hierarchical energy absorption is that it can effectively reduce the collision force, thereby achieving a buffering effect and having good energy absorption stability.

[0028] A highway traffic safety guardrail comprises a pair of fixing brackets 1.

[0029] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "With the continuous increase in the number of car ownership, traffic accidents have become more and more frequent. Once an accident occurs on a highway with a high speed, it often causes unbearable damage. This prompts us to find ways to minimize the damage caused by highway accidents, so higher performance requirements are put forward for highway safety guardrails." In combination with actual use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve this technical problem, a highway traffic safety guardrail is provided on this basis.

[0030] like Figure 1-4 As shown in the figure;

[0031] In combination with the above content, it also includes a sliding rod 2 arranged between the two fixed brackets 1, and the left and right ends of the sliding rod 2 are respectively connected with a left support plate 3 and a right support plate 4, the left support plate 3 and the right support plate 4 match the sliding rod 2, and the left support plate 3 and the right support plate 4 slide left and right on the sliding rod 2, and the sliding rod 2 at the outer ends of the left support plate 3 and the right support plate 4 is provided with a second buffer mechanism 5, and a plurality of first buffer mechanisms 6 are arranged in an array on the sliding rod 2 between the left support plate 3 and the right support plate 4.

[0032] In an optional embodiment, the second buffer mechanism 5 includes a sleeve 51 fixed on the left support plate 3 and a first spring 52 sleeved on the slide rod 2, the sleeve 51 matches the first spring 52, and the sleeve 51 is sleeved around the outer periphery of the first spring 52.

[0033] In this embodiment, when the left support plate 3 or the right support plate 4 receives an external force, the left support plate 3 pushes the sleeve 51 outward on the slide rod 2, and the first spring 52 performs a buffering effect.

[0034] In an optional embodiment, the first buffer mechanism 6 includes a front reinforcing rib 61 and a rear reinforcing rib 62 fixed between the left support plate 3 and the right support plate 4, and a limit ring 63 sleeved on the slide bar 2, the limit ring 63 matches the slide bar 2, and the limit ring 63 slides left and right on the slide bar 2, the front and rear side walls of the limit ring 63 are respectively fixed to the front support rod 64 and the rear support rod 65, the bottom ends of the front support rod 64 and the rear support rod 65 are connected by a connecting plate 66, the side wall of the rear support rod 65 is fixedly provided with a U-shaped bracket 67, and a roller 68 is movably provided on the U-shaped bracket 67 through a bearing, and a second spring 69 is sleeved on the slide bar 2 between several of the limit rings 63.

[0035] In this embodiment: when an out-of-control vehicle hits the roller 68, since the roller 68 is movably arranged on the U-shaped bracket 67, the out-of-control vehicle changes direction through the rotation of the roller 68 to prevent the vehicle from rushing out of the guardrail.
