Steel pipe inner wall anti-rust agent applicator for anti-rust engineering

The invention relates to an anti-rust agent applicator, in particular to a steel pipe inner wall anti-rust agent applicator for anti-rust engineering. The technical problem to be solved by the invention is to provide the steel pipe inner wall anti-rust agent applicator for the anti-rust engineering, which is uniform in application. According to the technical scheme, the steel pipe inner wall anti-rust agent applicator for the anti-rust engineering comprises: a mounting plate; a mounting ring, wherein the mounting ring is fixedly connected to the upper side of the mounting plate; and a fixing table, wherein the fixing table is fixedly connected to the upper side of the mounting ring. The device can be driven by a lifting mechanism to move along a whole steel pipe, so that a spraying mechanism can move to the deep position of the steel pipe, and the inner wall of the steel pipe is evenly coated with an anti-rust agent; the anti-rust agent on the inner wall of the steel pipe can be applied more uniformly through
