③ cleaning the column: cleaning water is inserted into the liquid storage tank 5 through the liquid injection hole 6, the water is directly sprayed on the cylinder through the liquid leakage hole 25 and the liquid seepage hole 7, the pneumatic power source switch is started, the air pipe 12 outputs negative pressure power to drive the helical blade 15 to rotate, so that the movable gear 17 and the tooth grooves 18 are meshed to drive the rust removal painting sleeve 3 to rotate, the paint brush 26 on the inner wall of the rust removal painting sleeve is driven to rotate, and oil stains left on the outer surface of the cylinder 24 after rust removal are cleaned by the water;

(5) painting work

Preparing spraying: after the column body is cleaned and dried, paint is poured into the liquid storage box 5 through the liquid injection hole 6, and is infiltrated onto the column body 24 through the liquid leakage hole 25 and the liquid infiltration port 7;

secondly, painting with slow paint: the pneumatic power source is opened slowly, negative pressure power is output to the air pipe 12, the spiral blade 15 is driven to rotate, the movable gear 17 and the tooth grooves 18 are meshed, the rust removing painting sleeve 3 is driven to rotate, the paint brush 26 on the inner wall of the rust removing painting sleeve rotates, and paint seeped through the liquid leakage hole 25 and the liquid seepage port 7 is sprayed to the surface of the cylinder 24 in a rotating mode;

③ painting repeatedly: when the rust removing spraying sleeve 3 runs to the end point of one end, stopping and switching the air pressing joint 11 at the other end, filling the liquid storage tank 5 with paint, opening the pneumatic power source at a high speed, adopting high-speed painting, and determining the number of times of back-and-forth painting according to the painting effect;

(6) and (3) finishing painting:

and after the ideal painting effect is achieved, reversely disassembling and ending according to the installation steps.

Firstly, closing the pneumatic power source to separate the pneumatic power source from the compressed air joint 11;

secondly, emptying the liquid storage tank 5, and preliminarily cleaning the oil stains on the liquid storage tank 5, the liquid injection hole 6, the liquid leakage hole 25, the liquid seepage hole 7 and the waste discharge hole 8;

thirdly, disassembling and cleaning: screwing off the bolt 10, disassembling the hollow ring combination 4, taking down and thoroughly cleaning the liquid storage system and the pneumatic system, and cleaning the waste storage rectangular box 20; thoroughly cleaning the rust removing painting sleeve 3, the gear 17, the tooth groove 18, the paint brush 26 and the like;

fourthly, the cleaned parts are disassembled and cleaned, and then the parts are placed into a special containing box for proper storage.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and extensions (such as power source modification, shape modification of the sleeve for removing rust, etc.) can be made without departing from the spirit of the invention, and such modifications and extensions are also considered to be within the scope of the invention.
