Description

Technical Field

[0001] The utility model relates to the field of expressways, in particular to a device for fixing a construction sign on an expressway. Background Art

[0002] Expressways are high-grade highways. Expressways refer to "highways that can accommodate an average annual day and night passenger car traffic volume of more than 25,000 vehicles, are specially designed for cars to travel at high speeds, and have full access control." Direct trunk lines with grade separations are also called expressways. The lighting of expressways belongs to the category of expressway electromechanical engineering. When driving on expressways at night, the visual environment deteriorates. The driver can roughly see the direction of the new road in front of the car and the nearby environment through the reflection of the headlights on the road surface and various reflective films, but does not have the ability to perceive environmental changes on a large scale, and cannot carefully distinguish the movements of surrounding vehicles and the location of obstacles, and it is difficult to discern the direction of the road ahead. Compared with daytime, the accident rate of driving at night is much higher. According to surveys and statistics from relevant departments, more than half of traffic fatalities occur at night. Calculated by weighted mileage, the death rate of traffic accidents at night is twice that of daytime. It can be seen that lighting is closely related to traffic safety.

[0003] At present, highway construction signs are usually fixed above the support frame, and their height is generally fixed, which is not conducive to up and down adjustment. In addition, when the support frame fixes the construction sign, the speed is slow and not conducive to current use. Therefore, we propose a highway construction sign fixing device to solve the above problems. Utility Model Content
