AI Technical Summary
Existing bridge railing painting equipment cannot accurately adjust the spray nozzle height for railings of different heights and complex shapes, resulting in uneven spraying and affecting coating quality and protective performance.
Employing a multi-set electric push rod, slide rail, and slider structure, combined with a laser rangefinder and displacement sensor, the system enables independent height adjustment for each nozzle. The controller precisely controls the extension and retraction of the electric push rods to ensure that the nozzles maintain a suitable spraying distance from the guardrail surface.
This effectively avoids problems such as uneven coating thickness and missed spraying, significantly improving the spraying quality and protective performance of bridge railings, and enhancing the precision and safety of the operation.
