Embodiment 1

[0044] like Figure 1-Figure 10As shown, a highway crash barrier includes a first support beam 10, a second support beam 20, and an anti-collision barrel 30 installed between the first support beam 10 and the second support beam 20, wherein: the first support The extension direction of beam 10 is parallel to the extension direction of second support beam 20; The front end is connected in a freely rotatable manner relative to the rear end of another first support rod 101; the second support beam 20 is formed by connecting a plurality of second support rods 201 in series, and one of the adjacent second support rods 201 The front end of the second support rod 201 is connected to the rear end of another second support rod 201 in a freely rotatable manner. The anti-collision barrel 30 is made of non-metallic material, has certain elasticity, and can absorb certain impact force.

[0045] In the embodiment of the present invention, when the vehicle hits the anti-collision guardrail...

Embodiment 2

[0055] like Figure 11 As shown, the difference between the crash barrier in this embodiment and Embodiment 1 is that the connection positions of the first and second connecting rods 1011, 1012 and the third and fourth connecting rods 2011 and 2012 in this embodiment are different. . Therefore, the description below focuses on the connection position in this embodiment. The description of the same or similar elements as those in Embodiment 1 is omitted.

[0056] like Figure 11 As shown, the vertical distance h between the first link 1011 and the third link 2011 1 The vertical distance h between the second link 1012 and the fourth link 2012 2 equal. Specifically, at the connection between the first connecting rod 1011 and the second connecting rod 1012, the rear end of the first connecting rod 1011 is located above the front end of the second connecting rod 1012; At the connection, the rear end of the third connecting rod 2011 is located above the front end of the fourth...

Embodiment 3

[0058] like Figure 12 As shown, the difference between the crash barrier in this embodiment and Embodiment 1 and Embodiment 2 lies in the first and second connecting rods 1011 and 1012 and the third and fourth connecting rods 2011 and 2012 in this embodiment The connection location is different. Therefore, the description below focuses on the connection position in this embodiment. The description of the same or similar elements as those in Embodiment 1 is omitted.

[0059] like Figure 12 As shown, the vertical distance h between the first link 1011 and the third link 2011 1 The vertical distance h between the second link 1012 and the fourth link 2012 2 equal. Specifically, at the connection between the first link 1011 and the second link 1012, the rear end of the first link 1011 is located below the front end of the second link 1012; At the connection, the rear end of the third connecting rod 2011 is located below the front end of the fourth connecting rod 2012, so th...

Abstract

The invention relates to the technical field of guardrails, in particular to a highway crash barrier. The highway crash barrier comprises a first support beam, a second support beam and an anti-collision barrel, wherein the extension direction of the first support beam is parallel to that of the second support beam; the first support beam is formed in a way that a plurality of first support rods are connected in series, and the front end of one first support rod in adjacent first support rods is connected with the rear end of the other first support rod in a free rotating mode; and the secondsupport beam is formed in a way that a plurality of second support rods are connected in series, and the front end of one second support rod in adjacent second support rods is connected with the rearend of the other second support rod in the free rotating mode. According to the embodiment of the highway crash barrier, the anti-collision barrel generates rolling friction so as to transfer and absorb impact force; and the plurality of the first support rods and the plurality of second support rods rotate relatively, so that corresponding buffering force is provided for the collision of vehicles, and the damage to the vehicles and passengers is further reduced.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to an anti-collision guardrail for expressways. Background technique [0002] Highway anti-collision barrier is the main form of semi-rigid barrier, which is a continuous structure of corrugated steel guardrails spliced ​​with each other and supported by the main column. It uses the deformation of the soil foundation, columns, and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction, preventing the vehicle from rushing out of the road, so as to protect the vehicle and passengers and reduce the loss caused by the accident. [0003] The high-speed anti-collision guardrail in the prior art mainly adopts wave beam guardrail, and the wave beam guardrail is the main form of semi-rigid guardrail, which is a continuous structure with corrugated steel guardrail panels spliced ​​with each other and suppor...
