Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to a surface painting device for expansion joints. Background Art

[0002] The compensator is also called an expansion joint or a telescopic joint, which is composed of a corrugated pipe that forms its working main body and accessories such as end pipes, brackets, flanges, and conduits. It belongs to a compensating element. The compensator utilizes the effective telescopic deformation of its working main body corrugated pipe to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by reasons such as thermal expansion and contraction, or to compensate for the axial, lateral, and angular displacements of pipelines, conduits, containers, etc.

[0003] When the expansion joint is spray-painted, due to the different distances between the concave and convex parts of the expansion joint and the spray head, the spraying is uneven, and there is even a possibility that some concave parts cannot be sprayed. Therefore, improvement is still needed. Summary of the Utility Model
