Embodiment 1

[0043] Such as Figure 1 to Figure 5 As shown, an isolation barrier for traffic safety provided by an embodiment of the present invention includes several isolation assemblies arranged side by side, and the isolation assembly includes a base 11, a first column 10, a second column, an upper beam 12, a lower beam 14 and a first The buffer rod 13 and the two ends of the lower beam 14 are respectively fixedly connected to the first column 10 and the second column, and the lower ends of the first column 10 and the second column are connected to the base 11, as Figure 4 and Figure 5 As shown, the isolation components also include:

[0044] The first baffle 102, the left and right sides of the first column 10 are hinged with the first baffle 102, and the upper end of the first baffle 102 is hinged to the first column 10;

[0045]The second baffle plate 104, the left and right sides of the second column are all hinged with the second baffle plate 104, and the lower end of the seco...

Embodiment 2

[0051] In the first embodiment, after the upper beam 12 is separated from the first column 10 and the second column, it is very easy to fall to the side lane, posing a threat to oncoming vehicles. In addition, when the barrier is subjected to a large impact, Due to the lack of effective buffering, the rigid connection between the isolation components is easy to break or part of the isolation barrier is overturned when impacted, causing hidden dangers to traffic safety, and affecting normal traffic at the same time, making it difficult to restore normal traffic in a short time. Therefore, this embodiment Zhongru Figure 4 , 6 Shown in and 7, also comprise linkage, it comprises two linkage mechanisms that are arranged up and down oppositely, linkage mechanism comprises mount 20, rotating shaft 21, stay cord 22, torsion spring 23, ratchet 24, ratchet 25 and return spring 26, The first baffle plate 102, the second baffle plate 104, and the side walls at both ends of the upper bea...

Embodiment 3

[0056] The vehicle is easy to catch fire after being in an accident, and it is easy to cause secondary accidents due to the lack of effective cushioning during impact. In order to improve safety, on the basis of embodiment one or two, such as Figure 8 to Figure 13 As shown, the present embodiment also includes a safety buffer device, which includes a drive rod 31, a runner 30, a drill bit 32 and a reaction box 40, the drive rod 31 is rotatably arranged in the upper beam 12, and the runner 30 is fixedly arranged on the drive rod 31, the stay cord 22 is wound around the runner 30, and when the stay cord 22 moves, it drives the runner 30 to rotate; the drive rod 31 is provided with a drive groove with a polygonal cross section, and the shape and drive of the upper half of the drill bit 32 The shape of the groove is suitable, and the drive rod 31 can drive the drill bit 32 to rotate when the drive rod 31 rotates. 32 synchronous rotation;

[0057] The reaction box 41 is fixedly a...

Abstract

The invention discloses an isolation fence for traffic safety, which belongs to the field of traffic. The device includes a plurality of isolation assemblies arranged side by side, the isolation assembly includes a base, a first column, a second column, an upper beam, a lower beam and a first buffer rod, and the isolation assembly further includes: a first baffle, the upper end of the first baffle is hinged to the first column; a second baffle, the lower end of the second baffle is hinged to the second column; and a first tightening screw, one end of the first tightening screw is hinged to the lower end of the first baffle, and the other end is threaded connected to the upper beam; a second tightening screw, one end of the second tightening screw is hinged to the upper end of the second baffle plate, and the other end is threadedly connected to the upper beam. The invention provides an isolation fence for traffic safety. When impacted, the first baffle plate and the second baffle plate can be turned to give way to avoid direct impact force on the beam. When impacted, it will move with the vehicle as a whole, so it is not easy to be harmed. vehicles or people.

Description

technical field [0001] The invention relates to the traffic field, in particular to an isolation barrier for traffic safety. Background technique [0002] Traffic barriers, also known as traffic guardrails, are used to isolate roads and isolate traffic from different directions so that they can drive in their own lanes. [0003] Existing barriers generally include a column, a beam and a base, the column is fixedly arranged on the base, and the beam is fixedly connected between the two columns. When a vehicle crashes into a guardrail due to improper driving or a vehicle crashes, due to the limited structural strength of the beam, the two ends of the beam are fixedly connected to the columns, and the structural strength is high, while the middle part has a weak supporting force, poor structural strength, and is most likely to break. The broken beam will form a free end, which will penetrate the window glass and pose a threat to the human body. Contents of the invention [...
