A pipe fitting inner wall spraying device

Abstract

The invention discloses a pipe inner wall spraying device which comprises a base frame, a movable frame which is telescopically arranged on the base frame, and a spraying group which can spray paint on the inner wall of a pipe member. The spraying group is rotatingly installed on the output end of the movable frame, the base frame is adjustably installed in the pipe member, the movable frame can drive the spraying group to protrude, and the spraying group can spray paint to the inner wall of a pipe member region where the spraying group is located. The pipe inner wall spraying device is integrally put into the pipe member by using the base frame and the movable frame, the position of the spraying group is adjusted by using the telescopic movable frame, the spraying group can spray paint tothe inner wall of the pipe member region where the spraying group is located, which is very convenient, and the spraying effect is controllable. In addition, the position of the base frame is adjustable in the pipe member, therefore, the continuous operation of the whole spraying device in the pipe member can be achieved, the position of the base frame relative to the inner wall of the pipe member is adjusted through a telescopic frame, the whole spraying device can adapt to pipe members of different pipe diameters, and the overall operability is strong.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a spraying device. Background technique [0002] With the development of society, the scope of use of large-scale pipe fittings is becoming wider and wider. Large-scale pipe fittings generally use steel pipes, which not only maintain their strength but also have a good scope of application. Since the pipe fittings are made of metal, they are easily corroded by the environment. If they are not handled properly, it is easy to cause the steel pipe to be corroded and damaged. The general industry will spray paint on the inner and outer side walls of the steel pipe for rust prevention. [0003] But when large-scale steel pipe inner wall carries out spraying operation, most are carried out paint spraying operation to pipe inner wall by manual hand-held paint spray gun. The operation in the steel pipe belongs to the confined space operation, and the safety risk factor ...

AI Technical Summary

Problems solved by technology

Spraying with a hand-held paint spray gun, the thickness of the paint is not easy to control, especially the paint spraying on the back is difficult to operate, which affects the quality of paint spraying
