Rainproof traffic sign convenient to overhaul and change
The invention belongs to the technical field of traffic equipment, and particularly relates to a rainproof traffic sign convenient to overhaul and replace.
Traffic refers to the industry engaged in passenger and cargo transportation and language and image-text transfer, including both transportation and post and telecommunications, and belongs to the third industry in the national economy. The transportation has five modes of railway, road, waterway, aviation and pipeline, and the post and telecommunications includes two contents of post and telecommunications. The traffic warning sign is a facility for transmitting specific information by using graphic symbols and characters to manage traffic and indicate driving direction so as to ensure smooth road and safe driving. The highway is suitable for highways, urban roads and all special highways, has the property of law, and vehicles and pedestrians must obey the property. Traffic signs are divided into two major categories, main signs and auxiliary signs. The main signs include four kinds of warning signs, forbidden signs, indicating signs and direction signs. The shape, color, size, pattern type and arrangement place of the road sign are all executed according to the current regulations of road traffic signs and marking lines. The indication mark is used for indicating vehicles and pedestrians to drive in a specified direction and place, is in a blue bottom and white pattern, and has a circular shape, a rectangular shape and a square shape. The indication mark can guide the correct driving direction and lane for the driver, and traffic violation is avoided.
The road traffic sign board provides road information and plays a role of road language; the traffic is commanded and controlled, and the traffic safety is guaranteed; the road is guided, and the driving efficiency is improved; the system provides law enforcement basis for traffic management departments, and is a facility for managing traffic and indicating driving directions to ensure smooth road and driving safety. In the city development process, the management department of the traffic sign faces to continuously patrol the traffic sign; the indication board is stained and needs to be repaired in time; the general problem that the road section indication boards with changed conditions need to be replaced in time. The repair or replacement of the small traffic sign is easy, the time consumption is not long, the influence on traffic is limited, but the repair or replacement of the small traffic sign is not simple for large and medium traffic signs, large tools such as cranes and the like are needed, a plurality of workers can complete the operation at the same time, the time and the labor are consumed, and the influence on road traffic is great. The turning type traffic sign disclosed in publication No. CN105133517A can store the backup board of the current traffic sign and the traffic sign needing to be replaced recently, and can be automatically replaced when needed, large tools such as cranes are not needed when the sign is replaced, the field operation is quite easy, and the sign suffering from fouling can be directly replaced when the traffic is idle, and the replacement can be completed without disassembling parts. However, it can be seen through its structure that discloses that the sign can not be taken in the inside of frame assembly completely, and this just causes the sign under the influence of environment, and the life-span can significantly reduce to if the sign damages, not the replacement is solved the problem even if, still need maintain it, and the open-page traffic sign that discloses for CN105133517A can not solve its convenient problem of maintaining. In summary, there is a need to design a traffic sign that is easy to repair and replace.
