Railway component painting device

Abstract

The present invention discloses a painting device for railway components. The whole machine is composed of a painting booth, a painting machine, a wheel feeding mechanism, and a dust removal device. The wheel feeding mechanism pushes the wheel set to the spraying station. The brake disc protection mechanism and the axle diameter protection mechanism are respectively lowered to the brake disc and the axle diameter by the cylinder lifting mechanism for protection. The wheel set starts to rotate, and the shaft body spray gun and the inner and outer auxiliary plate spray guns start automatic painting work. The angle and fan surface of the spray head are adjustable, and the spray flow rate is adjustable. When the painting stops, the wheel set stops rotating, the protection device retracts, and the wheel pushing mechanism pushes the wheel set out of the painting booth. This painting device has functions such as automatic wheel feeding, automatic spraying, and automatic wheel discharging, features of streamlined operation, uniform and beautiful painted surface, convenient operation, and little pollution, and is an ideal device for rust-proof painting work of railway maintenance wheel sets.

Our company has developed an automatic wheelset spraying equipment, which is a professional painting equipment for railway vehicle wheelsets. It is directly controlled by an industrial-grade PLC, and the manual process is clear and fast, truly realizing the real-time control and continuous operation of the test process. When designing the hardware, the scalability of the system is considered. The industrial-grade PLC control system, which is the most popular in China at present, is adopted in the host control. The system has strong scalability and reserves sufficient storage space for future program upgrades. Since the ladder diagram language of the PLC control method is adopted, it is very convenient for future maintenance and program modification. Summary of the Invention
