Title:
DEVICE FOR COATING INTERIOR OF PIPE
Document Type and Number:
Japanese Patent JP3877381
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for coating the interior of a pipe having such structure that coating efficiency of resin liquid cannot be reduced by effectively actuating an air flow in the pipe to a coating cup to secure high speed rotation.
SOLUTION: There are provide a driving wheel 3 which is rotatable receiving an air flow in a pipe generated by differential pressure in a pipe obtained when moved in the pipe and a an axial body 2 whose part is fitted in the driving wheel 3 to form a rotational support body and also in which a path 2b for resin liquid fed to the driving wheel 3. Between the end part of the driving wheel 3 and the end part of the axial body 2 opposite thereto in the axial direction, an oil containing mechanical seal 9 which can be abutted on the end part of the driving wheel 3 and an oil feeding part 10 having an oil discharge part opposite to the mechanical seal 9 are installed.
