Highway central guardrail

Abstract

The invention discloses a highway central guardrail and relates to the technical field of highway central guardrails. The guardrail comprises two guardrail assemblies, wherein each guardrail assemblycomprises a motor, a rotating shaft and a plurality of stand columns; the two ends of each rotating shaft are fixedly connected with rotating pieces; the rotating pieces are rotationally connected with fixing pieces; the motor is in power connection with one rotating piece; and the multiple stand columns are evenly and fixedly connected to the rotating shaft. Through the design of the two guardrail assemblies, the adjustment of the road width in a certain direction can be realized through the adjustment of the horizontal state and the vertical state of the stand columns in the two guardrail assemblies. Therefore, the width of the road in a certain direction can better adapt to the requirement of traffic flow, and traffic jam is reduced.

Description

technical field [0001] The invention relates to the technical field of highway central guardrails, in particular to a highway central guardrail. Background technique [0002] At present, central guardrails are set up on expressways at home and abroad. The main function is to separate two-way traffic flow, avoid accidents caused by vehicles turning around midway, and prevent accidents caused by dazzling lights on the opposite side at night. The specific forms include sun visor type and green belt type. No matter which form is adopted, the guardrails of the expressway are fixed guardrails at present. Since the fixed guardrail cannot be moved, when the two-way traffic flow is uneven, it is often impossible to effectively use the expressway resources to achieve dynamic adjustment. For example: at the beginning of a holiday in a large city, the traffic flow in the direction of the expressway out of the city increases rapidly and there is often serious congestion, while the road ...

AI Technical Summary

Problems solved by technology

Since the fixed guardrail cannot be moved, when the two-way traffic flow is uneven, it is often impossible to effectively use the expressway resources to achieve dynamic adjustment

For example: at the beginning of a holiday in a large city, the traffic flow in the direction of the expressway out of the city increases rapidly and there is often serious congestion, while the road vehicles in the direction of the city are small and idle, resulting in a great waste of resources; when the holiday is over, the situation is just right On the contrary, the rapid increase of traffic flow in the direction of the expressway into the city often leads to serious congestion, while the road vehicles in the direction of the city are small and idle, which also causes a great waste of resources

[0003] However, since the guardrails are fixed, it is impossible to adjust the road width and the number of lanes in a certain direction according to the actual situation, resulting in serious congestion in one direction, and basically no cars in the other direction, and the expressway resources cannot be allocated and used.
