Description
One, technical field:
The present invention relates to special spraying device for wind-power tower, belong to special spraying device.
Two, background technology:
As the wind-power tower of the crucial corollary equipment of wind-powered electricity generation unit, the accuracy of manufacture requires high, and except that form and position tolerances such as axiality, flatness, the depth of parallelism, linearity, unfitness of butt joint all should meet the demands, its tower tube requirement for anticorrosion was also quite strict.
Be exposed to the actual conditions of corrosive environment according to the wind-powered electricity generation unit, according to the requirement of ISO12944-2, the outer surface of tower tube belongs to corrosion classification C
5-M (not containing marine zone) and C
5-I inner surface belongs to corrosion classification C
4, according to the requirement of ISO12944-1, tower tube anti-corrosion protection grade is " for a long time ", useful life 15 years, and the hollow heart degree of depth was no more than 0.5mm in 20 years, and the spraying of tower tube requires three times lacquers of outer wall, coating layer thickness 280 μ m, two times lacquers of inwall, coating layer thickness 220 μ m.
The tradition method for paint spraying has two kinds:
The one, the qualified cylindrical shell of derusting by sandblasting (general length is about 20m) is placed on two blocks of parallel sleepers of certain distance apart, both sides fix with chock, begin spraying.The cylinder body outer wall upper end, the operator stands in spray gun spraying successively down on the cylindrical shell, and both sides utilize mobile platform to spray successively, and cylindrical shell lower end spray gun is spraying successively up.Finish the spraying of a lacquer, paint film repeats above-mentioned action after doing, and finishes two, three times lacquer sprayings.Cylinder inboard wall utilizes the mobile platform construction, finishes two times lacquer sprayings.
This spraying method, cylinder body outer wall spray gun can't guarantee all the time to cause the film thickness inequality perpendicular to the construction requirement of spraying face, leak spraying defectives such as spray, sagging, elephant skin, pin hole, paint waste is serious, and the sleeper place paint that also need fill spray separately at last is difficult to consistent with whole paint film.
The 2nd, cylindrical shell is placed on the turning rolls, carry out inside and outside wall spraying, revolve and turn around, finish a lacquer spraying, after paint film is done, finish two, three times lacquer sprayings successively.The paint quality of this spraying method, roller heavy damage roller contact position in rolling process need polish metallic luster again, sprays paint again.
Adopt above-mentioned two kinds of methods, the equal difficulty of cylinder body outer wall reaches requirement for anticorrosion.
Three, summary of the invention:
Defectives such as the objective of the invention is to overcome tower tube spraying film thickness inequality, leak spray, sagging, pin hole, elephant skin, paint waste are serious and a kind of special spraying device for wind-power tower is provided.
The present invention adopts following technical scheme:
A kind of special spraying device for wind-power tower, by cylinder (1), positioning and fixing dish (2), gusset (3), positioning retainer ring formations such as (4), it is characterized in that: with positioning and fixing dish (2), by the pattern requirement, be placed on the platform and smooth, by docking welding manner by hand with cross positioning and fixing dish (2) firm welding, find out central point, mark cylinder (1), positioning and fixing hole (5) position line and get out positioning and fixing hole (5), with cylinder (1) volume circle, by automatic welding manner welded drum (1) longitudinal joint, and the school circle is to qualified; Cylinder (1) is placed on the positioning and fixing dish (2) of having smoothed on the platform, and by the location of the cylinder position line on the positioning and fixing dish (2), point admittedly, gusset (3) is solid on cylinder (1) and positioning and fixing dish (2) by pattern requirement location, point; To locate, put good admittedly cylinder (1), gusset (3), symmetrical manual angle welding is welded on the positioning and fixing dish (2) simultaneously, prevents welding deformation, presses pattern welding positioning retainer ring (4), finishes the integral manufacturing of spray equipment;
Aforesaid a kind of special spraying device for wind-power tower, its feature also is: the steel plate of forming positioning and fixing dish (2) is steel plate (δ 32);
Aforesaid a kind of special spraying device for wind-power tower, its feature also is: positioning and fixing dish (2) is provided with a plurality of positioning and fixing hole (5), to adapt to many variety production.
Operation principle:
The first step, the preparation before the spraying: overhaul sanding rust cleaning situation, meet the Sa2.5 level requirement of GB8923-1998 standard-required.
Second step, the location: with driving tower tube to be sprayed is winched on the turning rolls, special spraying device is installed and fixed on tower tube two end flanges by bolt, after turning rolls is moved on the cylinder of special spraying device, use the cylinder back-up ring to locate.
In the 3rd step, spraying: the inboard utilizes the mobile platform spraying application; The outside, the operator stands in ground, along X to, spray gun keeps the upright position to spray successively with the tower tube all the time, and measures its wet-film thickness with the wet film card at any time, reaches requirement to guarantee build, according to tower tube diameter, highly, the difference of weight, adopt one-sided or two-side motor department clothes drive.Cylindrical shell rotates a circle, and finishes the working cycles of a lacquer, treat that paint film is done after, repeat above-mentioned working procedure, finish two, three times lacquer sprayings.
Employing special spraying device spraying, spray gun remain the position relation vertical with spraying face, do not have oblique spraying, and coating cloud is suave aerial, reduces paint waste, and the paint loss factor (is used 1 liter of paint in theory, actually needed 2 liters by original 2.) reduce to about 1.6, every tower shell ring economizes that paint is nearly 1/5, and painted surface is smooth, defectives such as no sag, pin hole, elephant skin, cylindrical shell need not to paint repair procedure, greatly improves coating quality.
The 4th step, packing: after treating that paint films is done, shed special spraying device, use the plastic sheeting entire package, wait to send out.
Four, description of drawings:
Fig. 1 is an agent structure schematic diagram of the present invention
Fig. 2 is a side view of the present invention
Agent set is made up of following four parts: 1, cylinder, 2, the positioning and fixing dish, 3, gusset, 4, positioning retainer ring, 5, the positioning and fixing hole.
Five, the specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
The first step: the positioning and fixing dish 2 that will be made up of steel plate (δ 32) by the pattern requirement, is placed on the platform and smooths, by manual butt joint welding manner, with cross positioning and fixing dish 2 firm welding.Find out central point, mark cylinder, bolt hole position line and get out bolt hole.
Second step: with cylinder 1 volume circle, by automatic welding manner welded drum 1 longitudinal joint, and the school circle is to qualified.
The 3rd step: cylinder 1 is placed on the positioning and fixing dish 2 of having smoothed on the platform, admittedly by the location of the cylinder position line on the positioning and fixing dish 2, point.Gusset 3 is solid on cylinder 1 and positioning and fixing dish 2 by pattern requirement location, point.
The 4th step: will locate, put good admittedly cylinder 1, gusset 3, symmetrical manual angle welding is welded on the positioning and fixing dish 2 simultaneously, prevents welding deformation.
The 5th step: press pattern welding positioning retainer ring 4, finish the integral manufacturing of spray equipment.
