[0002] Before existing round steel pipes are galvanized, brushing and rust removal operations are required, for which a round pipe polishing rust removal device is disclosed in Chinese Patent Application No. CN202322804893.2, which mainly rotates a polishing belt around a driving wheel to polish the surface of the round pipe.

[0003] However, the applicant has found at least the following technical problems in the process of implementing the technical solutions in the embodiments of the application:

[0004] 1. The round pipe needs to be axially moved to change the polishing position, but the roller body needs to have sufficient static friction force as a component for driving the rotation of the round pipe, so the static friction force of the roller body hinders the axial movement of the round pipe and affects the polishing operation.

[0005] 2. The polishing belt has a limited length and needs to be frequently replaced, which is relatively troublesome. INVENTION CONTENTS
