Device for brushing paint on inner wall of steel tubes

Abstract

The invention provides a device for brushing paint on an inner wall of a steel tube, which consists of a steel tube supporting part for supporting the steel tube to be brushed with paint, a paint injecting part for providing the required paint for the steel tube to be brushed, and a paint recovering device for recovering surplus paint. By adopting the device for brushing paint on the inner wall ofsteel tubes of the invention, the problems that brushing paint on the inner wall of steel tubes has slower speed and difficult operation, paint is difficult to be brushed evenly, brushing quality isdifficult to ensure, construction is inconvenient, construction quality and schedule can not be guaranteed and the like are overcome, thus achieving the effects of convenience and practicality.

Description

technical field [0001] The invention relates to a device for painting the inner wall of a steel pipe. Background technique [0002] The inner wall of the steel pipe for the construction installation of electromechanical pre-buried wires and the inner wall of the steel pipe for scaffolding usually need to be painted with anti-rust paint. At present, the commonly used method is to tie a piece of cotton yarn on the front end of a thin steel bar or thick iron wire, and paint the cotton yarn. Cotton yarn stretches into the inside of the steel pipe to paint. [0003] The inventor finds that there are at least the following problems in the prior art: because the method of extending the cotton yarn into the inside of the steel pipe to paint the paint is slow and difficult to operate, the paint is difficult to paint evenly, and the quality of painting cannot be guaranteed, and the construction is also difficult. It is very inconvenient, and the construction quality and progress cann...
