Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail painting, and specifically relates to an anti-corrosion painting device for a crash guardrail. Background Art

[0002] Currently, guardrails are designed for safety on both highways and bridges. Generally, the guardrails are corrugated guardrails, but the corrugated guardrails are generally not firm. Therefore, the current guardrails are provided with a base cement support seat, and the guardrail above is a cylindrical steel pipe. This kind of guardrail has good rigidity and saves materials compared with the corrugated guardrail. However, whether it is a corrugated guardrail or a steel pipe guardrail, it is necessary to regularly paint it to prevent the guardrail from rusting due to long-term exposure to the external environment, which will lead to damage to the rigidity of the guardrail and waste of materials. Therefore, it is necessary for sanitation workers to regularly maintain it, and the most effective maintenance is painting.

[0003] In the current prior art, the Chinese utility model patent CN218531387U discloses a guardrail painting device. The device is moved to the side of the guardrail through a push rod and universal wheels, the angle is adjusted so that the nozzle is aligned with the guardrail, the motor is started, the height of the nozzle is adjusted, and the motor is turned off. At the beginning, the nozzle is flush with the highest point of the guardrail. The water pump is turned on to start painting, and it moves while painting. After spraying at the same height, the motor is started again, the height of the nozzle is adjusted, and the motor is turned off to move the nozzle downward and spray again. The above working process is repeated until the entire guardrail is sprayed.

[0004] Although the above prior art can spray the guardrail, it is necessary to adjust the height and the angle of the nozzle up and down to complete the full spraying of the guardrail. This method results in low spraying efficiency and takes too much time to occupy the lane when facing the guardrail in the middle of the road. Summary of the Utility Model
