Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, and specifically relates to a cleaning device for surface treatment of the base material for refurbishing highway guardrails. Background Technique

[0002] The guardrails on highways are exposed to the air for a long time, and are exposed to wind, sun, automobile exhaust and dust pollution for a long time, which has a certain corrosive effect on the guardrails to a certain extent, causing the paint film to fall off and affecting the appearance. Therefore, it is very important to do a good job in the maintenance, protection and cleaning of highway guardrail plates. However, due to the geometric shape of the corrugated guardrail plate, when performing on-site base material treatment without demolition, a suitable process needs to be selected for operation.

[0003] At present, the most environmentally friendly treatment method is to use a high-pressure water gun for treatment, but the treatment process is prone to environmental pollution, and the cleaning of the site after treatment increases the operation process and the cost is relatively high. Therefore, it is particularly important to design a special outdoor guardrail cleaning device, which can construct safely and environmentally friendly outdoors, reduce the construction process and improve the construction efficiency.
