Road anti-collision pier

Abstract

The utility model provides a road anti-collision pier, which relates to the technical field of traffic safety and comprises an anti-collision pier body. According to the anti-collision pier, when a vehicle collides, the fan-shaped plate outside the anti-collision pier body can be collided, at the moment, the telescopic air bag between the fan-shaped plate and the anti-collision pier body can deform, and internal nitrogen is matched with deformation and compression generated by the telescopic air bag to absorb part of collision energy, so that the effect of buffering and unloading force on the fan-shaped plate is achieved; moreover, when the impact force generated by vehicle collision is too large, in the contraction process of the telescopic air bag, the limiting rod in the telescopic air bag slides into the inner cavity of the anti-collision pier body and finally abuts against the fixing block, the damper absorbs the collision energy at the moment, and therefore the impact force is further reduced, meanwhile, the reset spring stores the energy, and then the energy is released in the collision process. And a certain elastic support is provided, so that the impact energy is more effectively absorbed and dispersed, and the buffering effect of the anti-collision pier body is greatly improved.

Description

Technical Field

[0001] The utility model relates to the technical field of traffic safety, in particular to a highway anti-collision pier. Background Art

[0002] Highway crash barriers, also known as vehicle crash barriers, curb crash barriers or safety guardrails, are the most common type of road traffic facilities. They are mainly used to prevent vehicle collisions, ensure the safety of drivers, passengers and pedestrians in traffic accidents, and can also effectively absorb the energy when a vehicle hits the guardrail, reduce the degree of damage to the vehicle, and protect the driver's life.

[0003] In the prior art, the traditional crash cushion has limited cushioning effect when hit by a vehicle and cannot effectively absorb and disperse the impact energy. Such an impact may cause serious deformation or damage to the crash cushion, thereby causing harm to the vehicle and occupants. Therefore, in response to the above problems, we propose a new type of highway crash cushion. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the traditional crash cushion has limited buffering effect when hit by a vehicle and cannot effectively absorb and disperse the impact energy. Such an impact may cause serious deformation or damage to the crash cushion, thereby causing harm to the vehicle and occupants. A highway crash cushion is proposed to solve the problem that the traditional crash cushion has limited buffering effect when hit by a vehicle and cannot effectively absorb and disperse the impact energy. Such an impact may cause serious deformation or damage to the crash cushion, thereby causing harm to the vehicle and occupants.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a highway crash barrier, including a crash barrier body, a telescopic airbag is arranged on the left surface of the crash barrier body, a limiting rod is symmetrically fixedly connected to the left inner surface wall of the telescopic airbag, a fan-shaped plate is fixedly connected to the left surface of the telescopic airbag, mounting blocks are symmetrically fixedly connected to the inner surface wall of the crash barrier body near the right side, dampers are fixedly connected to the left surfaces of the two mounting blocks, the telescopic ends of the two dampers are fixedly connected to the fixing blocks, and the outer surfaces of the two dampers are sleeved with reset springs.

[0006] Preferably, an inflation nozzle is provided at a position near the left edge of the top of the telescopic airbag, and a dust cover is provided on the top of the inflation nozzle.

[0007] Preferably, a sealing ring is symmetrically embedded on the left surface of the crash pier body, and the outer surfaces of the two limiting rods respectively penetrate the outer surfaces of the two sealing rings and extend to the other side.

[0008] Preferably, the left ends of the two return springs are fixedly connected to the right surfaces of the two fixing blocks, and the right ends of the two return springs are fixedly connected to the left surfaces of the two mounting blocks.

[0009] Preferably, a base is fixedly connected to the bottom of the crash pier body, and a counterweight block is arranged at the inner bottom of the crash pier body, and the cross section of the counterweight block is arranged in a triangular shape.

[0010] Preferably, an extended bottom plate is fixedly connected to the right surface of the base, and a plurality of anti-slip strips are provided at the bottom of the extended bottom plate.

[0011] Preferably, two reinforcing rods are fixedly connected to the right surface of the crash pier body, and the bottom of the reinforcing rods is fixedly connected to the top of the extended bottom plate.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when a vehicle collides, it will hit the fan-shaped plate outside the crash pier body. At this time, the telescopic airbag between the fan-shaped plate and the crash pier body will be deformed, and the internal nitrogen will cooperate with the deformation and compression generated by the telescopic airbag to absorb part of the collision energy, thereby playing a role in buffering and unloading the fan-shaped plate. In addition, when the impact force generated by the vehicle collision is too large, during the contraction of the telescopic airbag, the internal limit rod will slide into the internal cavity of the crash pier body and finally hit the fixed block. At this time, the damper absorbs the energy of the impact, thereby further reducing the impact force. At the same time, the reset spring stores energy and then releases it during the collision to provide a certain elastic support, which more effectively absorbs and disperses the impact energy, thereby greatly improving the buffering effect of the crash pier body.

[0014] 2. In the utility model, when the impact force is too great, the base and the anti-collision pier body will move to the right as a whole, and the design of the extended bottom plate increases the contact area and stability between the base and the ground, thereby increasing the friction when the base slides on the ground and achieving a buffering effect.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a highway crash pier, including a crash pier body 11, a telescopic airbag 2 is arranged on the left surface of the crash pier body 11, a limit rod 23 is symmetrically fixedly connected to the left inner surface wall of the telescopic airbag 2, a sector plate 3 is fixedly connected to the left surface of the telescopic airbag 2, a mounting block 4 is symmetrically fixedly connected to the inner surface wall of the crash pier body 11 near the right side, a damper 41 is fixedly connected to the left surface of the two mounting blocks 4, and the telescopic ends of the two dampers 41 are fixedly connected to the fixing blocks 43. The outer surface of 41 is sleeved with a return spring 42, an inflation nozzle 21 is provided at the top of the telescopic airbag 2 near the left edge, and a dust cover 22 is sleeved on the top of the inflation nozzle 21, and a sealing ring 24 is symmetrically embedded on the left surface of the anti-collision pier body 11, and the outer surfaces of the two limit rods 23 respectively penetrate the outer surfaces of the two sealing rings 24 and extend to the other side, the left ends of the two return springs 42 are fixedly connected to the right surfaces of the two fixing blocks 43, and the right ends of the two return springs 42 are fixedly connected to the left surfaces of the two mounting blocks 4.

[0023] The effect achieved by the entire embodiment 1 is that when a vehicle collides, it will hit the fan-shaped plate 3 outside the crash pier body 11. At this time, the telescopic airbag 2 between the fan-shaped plate 3 and the crash pier body 11 will be deformed, and the internal nitrogen will cooperate with the deformation and compression generated by the telescopic airbag 2 to absorb part of the collision energy, thereby playing a role in buffering and unloading the fan-shaped plate 3. In addition, when the impact force generated by the vehicle collision is too large, during the contraction of the telescopic airbag 2, the internal limit rod 23 will slide into the internal cavity of the crash pier body 11, and finally hit the fixed block 43. At this time, the damper 41 absorbs the energy of the impact, thereby further reducing the impact force. At the same time, the reset spring 42 stores energy and then releases it during the collision to provide a certain elastic support. , which more effectively absorbs and disperses the impact energy, thereby greatly improving the buffering effect of the crash pier body 11 and protecting the vehicle and occupants. When the nitrogen inside the telescopic airbag 2 is insufficient, open the dust cover 22, and then inflate it through the inflation nozzle 21. After inflating, cover the dust cover 22. Filling nitrogen is more convenient, and the counterweight block 44 is triangular and has good stability. It can increase the impact force on the front of the crash pier body 11 inside, so that a part of the inside of the crash pier body 11 can be set to a hollow state, thereby reducing the material usage and the overall weight while ensuring the strength. The sealing ring 24 improves the sealing effect. The mounting block 4 is used to install the damper 41 and the return spring 42.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the bottom of the crash pier body 11 is fixedly connected to the base 1, the inner bottom of the crash pier body 11 is provided with a counterweight block 44, the cross-section of the counterweight block 44 is triangular, the right surface of the base 1 is fixedly connected to the extension bottom plate 5, the bottom of the extension bottom plate 5 is provided with a plurality of anti-slip strips 52, and the right surface of the crash pier body 11 is fixedly connected to two reinforcing rods 51, and the bottom of the reinforcing rods 51 is fixedly connected to the top of the extension bottom plate 5.

[0025] The effect achieved by the entire embodiment 2 is that when the impact force is too great, the base 1 and the crash pier body 11 will move to the right as a whole, and the design of the extended bottom plate 5 increases the contact area and stability between the base 1 and the ground, so that the friction force of the base 1 is increased when it slides on the ground, which has a buffering effect, and the reinforcing rod 51 better improves the stability and strength of the crash pier body 11 when it is hit.

[0026] Working principle: When a vehicle collides, it will hit the fan-shaped plate 3 outside the crash pier body 11. At this time, the telescopic airbag 2 between the fan-shaped plate 3 and the crash pier body 11 will be deformed, and the internal nitrogen will cooperate with the deformation and compression generated by the telescopic airbag 2 to absorb part of the collision energy, thereby playing a role in buffering and unloading the fan-shaped plate 3. In addition, when the impact force generated by the vehicle collision is too large, during the contraction of the telescopic airbag 2, the internal limit rod 23 will slide into the internal cavity of the crash pier body 11, and finally hit the fixed block 43. At this time, the damper 41 absorbs the energy of the impact, thereby further reducing the impact force. At the same time, the return spring 42 stores energy and then releases it during the impact, providing a certain amount of elastic support, which more effectively absorbs and disperses the impact energy, thereby greatly improving the buffering effect of the crash pier body 11. When the impact force is too large, the base 1 and the crash pier body 11 will move to the right as a whole, and the design of the extended bottom plate 5 increases the contact area and stability between the base 1 and the ground, thereby increasing the friction force when the base 1 slides on the ground, which has a buffering effect, and the reinforcing rod 51 better improves the stability and strength of the crash pier body 11 during impact.
