Title:
STEEL BRIDGE AUTOMATED COATING APPARATUS AND FILM COATING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/127262
Kind Code:
A1
Abstract:
A steel bridge automated coating apparatus and a film coating method thereof. The steel bridge automated coating apparatus comprises a planar movement mechanism and a spray-coating component arranged thereon. The spray-coating component comprises two spray head assemblies (3, 6), a quick air-drying mechanism (4) and a paintwork dent detection mechanism (5) that are disposed between the two spray head assemblies (3, 6), and two telescopic pushing mechanisms (12) that respectively drive the two spray head assemblies (3, 6) to move linearly. During spray coating of a primer, the two spray head assemblies (3, 6) operate cooperatively, and the telescopic pushing mechanisms (12) drive the spray head assemblies (3, 6) to move within a travel range. During movement, the spray head assemblies (3, 6) spray-coat a steel member area covered thereby, wherein the front spray head assembly (3, 6) in the movement direction of the planar movement mechanism performs primary spray-coating, and the rear spray head assembly (3, 6) performs compensatory spray-coating on an area where a detected dent is located. By means of the apparatus, a primary spray-coating result is inspected in real time, and secondary spray-coating for compensation is performed on a dent portion in a timely manner, such that the surface of a primer is uniform, and therefore, the thickness and surface flatness of a finishing coat are within an ideal range.
