Abstract

The utility model relates to an automatic sand-blasting rust-removing and automatic paint-spraying device for the internal wall of the steel tank, which makes a reverse umbrella-shaped expansion bracket which is provided with three spray guns arranged in a steel tank; the reverse umbrella-shaped expansion bracket is drawn for the automatic timing ascending (descending) by an electric hoist steel cable on the external side of the tank; the automatic timing left (right) rotation of the spray gun can be controlled by an electric magnet, and the compressed air generated by an air compressor makes the steel sand (or paint) transmitted to the spray gun through a rubber pipe for sand blasting and rust removing (or paint spraying). Each telescopic arm is split into four sections; a section is sheathed in a section and is freely extended and shortened, and the automatic sand-blasting rust-removing and automatic paint-spraying device for the internal wall of the steel tank is suitable for the automatic sand blasting, the automatic rust removing, and the automatic paint spraying on the internal wall of the steel tank with the diameter o 2 meters to 6 meters and the height 30 meters.

Description

Cylinder of steel inwall automatic sand blasting and automatic spray-paint device

The utility model relates to a kind of cylinder of steel inwall automatic sand blasting and automatic spray-paint device given.

At present, known cylinder of steel inwall derusting by sandblasting and spraying paint is that tower is established scaffold in jar, and the workman crawls in the cylinder of steel, and pistol sprays the steel sand rust cleaning to tank skin, and then sprays paint.The one, working condition is too abominable dangerous, and steel sand splashes, iron rust fills the air, coat with lacquer the smell people that chokes feels sick dizzy poisonous, noise above 120 decibels, very big to human health damage.The 2nd, the efficient of can not working continuously is low.The 3rd, rust cleaning and spraying lacquer are all inhomogeneous, of poor quality.

The purpose of this utility model provides a kind of energy and gives cylinder of steel inwall automatic sand blasting, also can spray the device of lacquer automatically.One does not need the people to advance grasps operation in the cylinder of steel, guarantee that the person is healthy and safe; The two efficient height of can working continuously; The 3rd, the derusting by sandblasting and the homogeneous quality that sprays paint are good.

The purpose of this utility model is achieved in that will the expansion bracket of falling the umbrella shape lifting up in the cylinder of steel traction with jar steel wire rope of outer electronic cucurbit hangs liter (decline).Three arm ends at the expansion bracket of falling the umbrella shape are installed electromagnet, spray gun, are connected with jar outer air compressor machine, a steel sand jar (or paint can) with sebific duct.With compressed air steel sand (or lacquer) is transported to spray gun by sebific duct, be injected into the purpose that tank skin reaches rust cleaning (or spraying paint).Electromagnet attracts spray gun deflection, utilizes the reaction force that sprays to promote the expansion bracket of falling umbrella shape integral left (right side) rotation.The control electromagnet regularly alternately attracts, and controls electric block simultaneously and regularly rises (falling) and can realize automatically evenly derusting by sandblasting and the purpose of spraying paint.

Owing to adopt such scheme, can realize cylinder of steel inwall automatic sand blasting and auto spray painting.One does not need the people to advance operation in the cylinder of steel, guarantees that the person is healthy and safe; The two efficient height of can working continuously; The 3rd, derusting by sandblasting (or spraying paint) homogeneous quality is good.

Below in conjunction with drawings and Examples the utility model is further specified.

Support (8) is installed on the top of cylinder of steel (1).It is three that the steel wire rope (9) of electric block (10) connects behind the hole under the last Kong Fangzhi of cylinder of steel (1) through pulley (7), is connected firmly with suspension ring (15) respectively.Remove set bolt (13) and each telescopic arm is shortened and bring together, change-over switch (ZK) is allocated to " liters " shelves, by manual knob (AK) electric block (10) rotation, the expansion bracket of falling the umbrella shape (3) integral body after steel wire rope (9) will be brought together is lifted up in the cylinder of steel (1).With each telescopic arm support exhibition elongation, set up set bolt (13), but so just constitute both ascending, descending again, simultaneously movable platform that also can left and right rotation.

Three spray guns (2) and sebific duct (4) are connected to air compressor machine (5).Adjust the distance of three pairs of electromagnet (11), make 3 °～8 ° of the angles of the left and right deflection of spray gun (2) also identical.Start air compressor machine (5) and utilize compressed air that the steel sand in the steel sand jar (6) is transported to the inwall of spray gun (2) injection to cylinder of steel (1) through leather hose (4), eliminate rust.Rust cleaning finishes, only blow air will float the rust blow clean.Change steel sand jar (6) into paint can again, spray gun (2) changes spray gun for paint into, can spray lacquer automatically by said procedure.

Stir change-over switch (ZK) and rise or fall, the time relay (S is adjusted in decision spray from bottom to top or spray from top to bottom ₁) time and the speed of (descending) spray in the decision.Adjust the time relay (S ₂And S ₃) time interval and the speed of the left and right rotation of decision spray.Also available computers programme-control.

Each telescopic arm (12) of the expansion bracket of falling the umbrella shape of the present utility model (3) is made rectangle, circle or polygon with metal, nylon or fiberglass, is divided into four sections, and one section is enclosed within one section, can extend arbitrarily, shortens, fix.Be suitable for 2～6 meters of diameter phi, cylinder of steel automatic sand blasting and the auto spray painting of height below 30 meters.
