[0026] When in use, first place the subway station guardrail in the center on the vacant rack 18, then start the external paint pump to transport paint into the fixed pipe 9, and under the action of pressure, the paint is sprayed downward through multiple paint spray heads 10, and the first servo motor 6 is started to drive the screw 5 to rotate, and the screw 5 drives the moving seat 8 to move horizontally, so that the guardrail can be sprayed in a scanning manner;

[0027] After the spraying is completed on the guardrail, the output ends of the two electric push rods 17 are started to extend forward, and the two electric push rods 17 drive the corresponding square rods 15 to move, and the two square rods 15 drive the corresponding two C-shaped claws 16 to move. Finally, the four C-shaped claws 16 will be clamped on both sides of the guardrail in pairs, and then the output end of the hydraulic cylinder 4 is started to retract downward, and the hydraulic cylinder 4 drives the lifting plate 3 to move downward, gradually away from the guardrail, and will not hinder the subsequent rotation of the guardrail. After that, the two second servo motors 12 are started to run, driving the two rotating disks 1 3 rotates 180°, and driven by the two rotating disks 13, the two square sleeves 14 and the two square rods 15 rotate, and the two square rods 15 drive the corresponding C-shaped claws 16 to rotate, so that the guardrail can be turned over. After the guardrail is turned over, the output end of the hydraulic cylinder 4 is started to extend, driving the lifting plate 3 to reset upward, and then the output ends of the two electric push rods 17 are started to retract, and the two square rods 15 will move backwards, so that the C-shaped claws 16 are separated from the guardrail, and finally the guardrail can continue to be painted after the turnover.
