Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a highway roller-type anti-collision, buffering and shock-absorbing guardrail. Background Art

[0002] In traffic accidents, traditional guardrails have a high side impact stiffness, which can lead to serious damage to vehicles and guardrails. Current roller-type anti-collision guardrails rotate to absorb the impact force when a vehicle collides with the guardrail, effectively correcting the vehicle's direction of travel.

[0003] However, most of the adjustable road and bridge guardrails currently on the market cannot disperse and reduce the impact force of vehicles hitting the guardrails. The vehicle impact force still causes serious damage to the guardrails, which shortens the service life of the guardrails. Utility Model Content

[0026] like Figures 1 to 3 As shown, an embodiment of the present utility model provides a highway roller-type anti-collision buffer and shock-absorbing guardrail, which includes: a horizontal plate and a buffer portion;

[0027] The horizontal plate includes an upper horizontal plate 1 and a lower horizontal plate 2;

[0028] The buffer part includes a first guide rod 3, a second guide rod 4 and a plurality of buffer mechanisms. The first guide rod 3 is horizontally arranged on the lower surface of the upper horizontal plate 1, and the second guide rod 4 is horizontally arranged on the upper surface of the lower horizontal plate 2. The buffer mechanism includes a central axis 5, a first roller 6 and two buffer components. The first roller 6 is sleeved on the central axis 5. The buffer component includes a slider 7, a transverse spring 8 and a limit plate 9 arranged in sequence along the axial direction of the guide rod. The slider 7 is slidably connected to the first guide rod 3 or the second guide rod 4. The transverse spring 8 is sleeved on the first guide rod 3 or the second guide rod 4. The limit plate 9 is fixedly connected to the first guide rod 3 or the second guide rod 4. The sliders 7 of the two buffer components are respectively connected to the opposite ends of the central axis 5.

[0029] The working process of a highway roller-type anti-collision buffer and shock-absorbing guardrail is as follows:

[0030] When a vehicle traveling on the road collides with a roadside guardrail, the first rollers 6 absorb the impact force by rotating and correct the direction of the vehicle at the same time;

[0031] At the same time, the central shaft 5 drives the slider 7 to move along the first guide rod 3 or the second guide rod 4 toward the limit plate 9, and the multiple transverse springs 8 on the first guide rod 3 or the second guide rod 4 are compressed in sequence to offset the impact force in the horizontal direction of the vehicle;

[0032] In the above process, the impact force of the vehicle is elastically buffered, which reduces the damage to the vehicle itself and also reduces the damage to the guardrail caused by the impact force of the vehicle.

[0033] Specifically, both ends of the first guide rod 3 are fixedly connected to the upper horizontal plate 1 , and both ends of the second guide rod 4 are fixedly connected to the lower horizontal plate 2 .

[0034] Specifically, for a two-way highway, the shock-absorbing guardrail is set on one side of the highway. Along the direction of vehicle travel, the slider 7, transverse spring 8 and limit plate 9 are arranged in sequence. When a one-way vehicle scratches and hits the first roller 6 outside the central axis 5, the slider 7 is driven to compress the transverse spring 8. The limit plate 9 is fixedly welded to the first guide rod 3 or the second guide rod 4 to ensure the compression amount of the transverse spring 8.

[0035] In a specific embodiment, the buffer component also includes a longitudinal spring 10, a sleeve 11 and a sleeve 12, the sleeve 12 is fixedly connected to the slider 7, the sleeve 11 is fixedly connected to the end of the center shaft 5, one end of the longitudinal spring 10 is fixedly connected to the sleeve 12, and the other end is fixedly connected to the sleeve 11.

[0036] In this embodiment, specifically, when a vehicle hits the guardrail, the multiple first rollers 6 rotate, and at the same time, the longitudinal springs 10 at the upper and lower ends of the central axis 5 can also bend and stretch to absorb the impact force of the vehicle, preventing the central axis 5 of the guardrail from rigidly receiving the impact of the vehicle and seriously damaging the guardrail structure.

[0037] In a specific embodiment, the number of the first guide rods 3 and the second guide rods 4 are both two, the number of the transverse springs 8 and the limit plates 9 of each of the buffer components are both two, the two first guide rods 3 are respectively slidably connected to the opposite sides of the slider 7 at the upper end of the central shaft 5, the two second guide rods 4 are respectively slidably connected to the opposite sides of the slider 7 at the lower end of the central shaft 5, and the sleeve 12 is located at the center of the slider 7.

[0038] In this embodiment, specifically, each transverse spring 8 and each limit plate 9 of the buffer component at the upper end of the central shaft 5 is correspondingly arranged on the axial side of one of the first guide rods 3; each transverse spring 8 and each limit plate 9 of the buffer component at the lower end of the central shaft 5 is correspondingly arranged on the axial side of one of the second guide rods 4;

[0039] The first guide rod 3 is slidably connected to the through hole on the opposite side of the slider 7 at the upper end of the central shaft 5 , and the second guide rod 4 is slidably connected to the through hole on the opposite side of the slider 7 at the lower end of the central shaft 5 .

[0040] Each slider 7 slides horizontally along the two guide rods, and the movement of the slider 7 is more stable. The slider 7 will not swing left and right, and the central shaft 5 will not swing.

[0042] In this embodiment, specifically, each column 13 is buried below the ground, and the columns 13 are fixedly connected to the lower horizontal plate 2 and the upper horizontal plate 1, respectively, to ensure the positional stability of the upper horizontal plate 1 and the lower horizontal plate 2 relative to the ground;

[0043] At the same time, the column 13 between the upper horizontal plate 1 and the lower horizontal plate 2 is nested in the second roller 14. When a vehicle collides with the second roller 14, the second roller 14 can also rotate to absorb the impact force of the vehicle.

[0044] In a specific embodiment, the length of the column 13 located below the lower horizontal plate 2 is greater than the length of the central axis 5 .

[0045] In this embodiment, specifically, the length of the column 13 below the lower horizontal plate 2 is greater than the length of the central axis 5, and the length of the column 13 that can be buried is greater than the length of the central axis 5. After multiple columns 13 are buried, they can provide sufficient support force for the guardrail on the ground.

[0046] In a specific embodiment, the distance between two adjacent columns 13 is no more than 4 meters, and the length of the column 13 located below the lower horizontal plate 2 is no less than 60 cm.

[0047] In this embodiment, specifically, two adjacent columns 13 provide support for a guardrail structure with an intermediate length of no more than 4m to prevent accident vehicles from running out of the driving lane; at the same time, the length of the column 13 below the lower horizontal plate 2 is no less than 60cm, and the length of each column 13 that can be buried is no less than 60cm.
