[0002] The highway guardrail plate is composed of two corrugated steel guardrail plates and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail plates. By inserting and pulling out the columns, they can be conveniently inserted into the pre-set insertion holes at the openings, playing a role in isolation and protection. At the same time, it echoes the guardrail belt on the outer edge of the highway, being neat, unified, and aesthetically matched. In order to prevent the corrugated guardrail plate from rusting, it usually needs to be painted on its surface. A painting device for highway corrugated guardrails proposed in the prior art publication number CN213762549U includes a fixing plate. A bearing is embedded inside the fixing plate. The inner wall of the bearing is fixedly connected with a support member. One end of the support member is fixedly connected with a roller. A conveyor belt is sleeved on the surface of the roller. One side of the fixing plate is fixedly connected with a first mounting plate. A slide rail is fixedly mounted on the upper surface of the first mounting plate. A rack is slidably connected inside the slide rail. However, during processing, only one side surface of the highway guardrail plate is spray-treated. After spraying, due to the lack of a structure that can automatically turn over, manual turning is required, consuming manpower and time. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a painting device for highway corrugated guardrails that can drive the corrugated guardrail plate to rotate and turn over, perform comprehensive spraying on it, reduce manual operation, and improve work efficiency.

[0004] A painting device for highway corrugated guardrails of the utility model includes a frame, multiple fixing plates, multiple legs, a conveyor belt, a box body, a clamping assembly, a turning mechanism, a spraying assembly, and a drying assembly.
