Description

Technical Field

[0001] The utility model relates to a polishing device, in particular to a pipeline surface polishing device. Background Art

[0002] As a tool for diversion, pipes play an important role both in industry and in people's daily lives. However, for some iron pipes, the outer surface of the pipes will rust due to long-term storage. In order to ensure the service life of the pipes, the pipes need to be polished and then sprayed with anti-corrosion coating on the outer surface, which requires the use of a polishing device.

[0003] For example, a pipe surface grinding device disclosed in Chinese patent publication number CN217800609U includes a base, a grinding mechanism, a support roller mechanism and a pressure roller mechanism fixed at both ends of the base. Each support roller mechanism includes two opposing support rollers located on the outside of the pipe and a servo motor that drives the corresponding support rollers to rotate. A first sliding groove for the pressure roller mechanism to slide is provided at both ends of the base. Each pressure roller mechanism includes a telescopic platform and a pressure roller located above the telescopic platform. The pressure roller can move and abut against the inside of the pipe. Supporting and rotating the pipe by the support roller mechanism helps to grind the outer surface of the pipe. Inserting the pressure roller mechanism into the pipe to cooperate with the support roller mechanism to clamp the pipe prevents the pipe from shaking during grinding, thereby improving the stability of the pipe during grinding.

[0004] Some problems were found during use of the above-mentioned existing pipe surface grinding device. First, the support roller mechanism was fixedly installed on the base, which resulted in the inability to adjust the spacing between the support roller mechanisms, and thus the inability to effectively support and clamp shorter pipes. Secondly, the grinding wheel was pushed into contact with the pipe surface by a spring, and there was no limiting mechanism, resulting in the problem that the thickness of the grinding wheel grinding could not be guaranteed.
