Description

Technical Field

[0001] The utility model specifically relates to the technical field of spray painting, in particular to a roadside guardrail renovation spray painting device. Background Art

[0002] On both sides of modern roads, there are various guardrails. The function of the guardrail is to absorb collision energy by using the deformation of the soil foundation, columns and beams, so as to change the direction of the out-of-control vehicle or prevent the vehicle from running off the road, so as to protect the vehicle and passengers and reduce the losses caused by accidents. However, as the guardrail ages, the paint on the surface of the metal guardrail in the guardrail will gradually fall off, resulting in the guardrail being unable to reflect light or achieve a warning effect when driving at night. At the same time, the paint on the outer surface of the metal guardrail will also play a protective role. After the paint falls off, the service life of the metal guardrail will be greatly reduced. At this time, the surface of the metal guardrail needs to be repainted.

[0003] The Chinese invention patent with announcement number: CN115301449B discloses a device for uniformly spraying paint on pipes, including a fixed frame, a guide rod, a nozzle, a support assembly, an adjustment assembly and a drive assembly. The pipe to be sprayed is inserted into the outside of the support rod. According to the different lengths of the support rod inserted into the support rod for pipes of different diameters, the adjustment assembly timely adjusts the distance between the sliding block and the fixed ring so that the pipes arranged on the support rod abut against each other, thereby preventing the paint from leaking from the gap between the pipes and reducing the waste of paint. The nozzle is driven by the first drive unit to reciprocate on the guide rod so that the paint is evenly sprayed on the pipe through the nozzle. The second drive unit drives multiple sliding blocks to slide along the annular slide groove at the same time, and the third drive unit drives multiple support rods to rotate, spraying multiple pipes at the same time, reducing the waste of paint in the process of spraying the pipes, and improving the efficiency of pipe spraying.

[0004] In the process of manual spray painting or spray painting using existing technology, the thickness of the paint surface is often unable to be controlled, resulting in cracking or peeling of the paint surface after spraying. At the same time, manual spray painting causes physical damage to the construction workers. Summary of the invention
