Description

Technical Field

[0001] The present invention relates to the technical field of bridge component spraying, and more particularly to an intelligent production line for bridge component spraying. Background Art

[0002] Bridges are important structures that connect transportation networks, and the quality of their components directly affects the safety and durability of bridges. With the continuous development of modern bridge engineering, the manufacturing accuracy and surface treatment requirements for bridge components are becoming increasingly higher. Spraying, as a surface treatment technology, can effectively improve the corrosion resistance, wear resistance and aesthetics of components.

[0003] Traditional bridge parts spraying processes are mostly manual, with problems such as low efficiency, unstable quality, and serious environmental pollution. Manual spraying relies on the experience and skills of workers, and it is difficult to ensure the uniformity and consistency of spraying. In addition, a large amount of harmful gases and dust will be generated during the spraying process, which will affect the health of workers and the environment.

[0004] With the advancement of Industry 4.0 and intelligent manufacturing, intelligent spraying technology has emerged. Intelligent spraying technology realizes the automation, intelligence and informatization of the spraying process by integrating advanced automation equipment, robotics, computer control systems, etc., effectively improving production efficiency and product quality, and reducing production costs and environmental pollution. With the continuous expansion of infrastructure construction, the demand for bridge parts is growing. The application of intelligent spraying production lines will greatly improve production efficiency, reduce production costs, improve product quality, and meet the market demand for high-performance bridge parts. At the same time, the promotion and application of intelligent production lines will also promote technological progress and industrial upgrading in related industries.
