Description

Technical Field

[0002] With the continuous increase in the operating mileage of bridges and roads in my country, a large number of highway supporting facilities are under the maintenance and management stage of the construction pipeline. The circular steel crash barrier with color coating installed on the concrete guardrails on both sides of the road bridge is also one of the highway supporting facilities. With the increase of application time, a large number of steel crash barrier guardrails have aging phenomena such as dirt contamination, fading, and paint peeling on the surface due to oxidation, exposure to dust, sand, and ultraviolet radiation, resulting in them being unable to play their original road warning role normally, posing a serious safety hazard to the personal and material safety of passing vehicles and drivers and passengers.

[0003] At present, when steel crash barrier guardrails fade and peel, they are still mainly cleaned and repainted manually. The feasibility of using manual operation for local maintenance is acceptable, but in the future, when a large number of long-distance steel crash barrier guardrails need to be cleaned and repainted due to aging, if manual operation is still used, it will result in high maintenance costs, low construction efficiency, and uneven spraying quality. Therefore, there is an urgent need for an integrated grinding, cleaning and spraying maintenance device for crash barrier guardrails. Utility Model Content
