Detailed Description
The present invention is further illustrated by the following specific examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides a two steel pipe inner walls air-dry device on line, comprises location portion, portion of being close, the portion of blowing, location portion, portion of being close arrange side by side, the portion of blowing sets up in the portion of being close. The positioning part is used for positioning the steel pipe so as to facilitate blowing; the approaching part is used for enabling the air nozzle to approach the steel pipe and enabling high-pressure airflow to be blown into the inner wall of the steel pipe; the blowing part is used for blowing high-pressure airflow into the steel pipe.
The approaching part consists of an approaching part frame 1, a push-pull cylinder 2, a cylinder bracket 3, a guide sliding bar 4 and a tuyere bracket 6, the cylinder bracket is fixedly arranged on the top surface of the approaching part frame, the rear part of the push-pull cylinder is horizontally and fixedly arranged on the cylinder bracket, the front end of the push-pull cylinder is fixedly arranged with the tuyere bracket, the guide sliding bar is arranged on the cylinder bracket in a sliding way, the front end of the guide sliding bar is fixedly arranged with the tuyere bracket,
