In some embodiments, the air pressure control unit 223 may include a gauge head and a three-point filter device to control the pressure of the air output by the air pressure drum 222 .

In practical applications, the spraying assembly 22 may also include other components to realize the spraying of paint. For example, paint for spraying can be stored in the paint supply bucket 221 . When the liquid level sensing device in the spraying assembly 22 receives the signal, the rotary joint of the suction port of the paint supply bucket 221 starts to absorb the paint. The amount of paint supply is controlled by automatically adjusting the throat of the rotary joint of the suction port, the piston sealing ring and the pressure control degree of compression. Among them, this adjustment method can prolong the service life of the piston sealing ring. Next, the paint is delivered through the cylinder pressure. When the liquid level sensing device in the spraying assembly 22 receives the material signal, the air valve connected to the air pressure bucket 222 is opened to deliver the paint to the high-pressure paint spraying pipe. Finally, the transfer valve of the spray gun 220 is opened, so that the air and paint in the conveying pipe are sprayed by the spray gun 220 on the area to be sprayed (ie, the outer wall of the building).

In the process of spraying, the ratio of paint to air, the supply of paint, the time of application, and the distance of spraying can be adjusted according to the effect of spraying. For example, the distance of spraying can be 45-60cm from the outer wall, but not limited thereto. When the spray gun 220 is too close to the outer wall, the spraying operation can be temporarily stopped, and the spraying operation can be continued until the position of the spraying component 22 is moved to a safe distance. It should be reminded that the above description is only an implementation aspect of the present application, and should not be regarded as a limitation of the present application. In other embodiments, the spray assembly 22 may operate in a manner other than that described above.

In some embodiments, the drive assembly 23 may be a synchronous motor, and the stretching of the lift rope 12 in the second direction DR2 is controlled by an encoder.

The surface profile detector 24 is disposed on the stage 20, and the surface profile detector 24 scans the area to be sprayed to obtain scanning information. For example, the surface profile detector may be a 3D scanner, which acquires profile data (ie, scan information) of the outer wall by detecting, and transmits the data to the control unit 25 .

The control assembly 25 is disposed on the carrier 20 , and the control assembly 25 is electrically connected to the lifting device 1 , the spraying assembly 22 , the driving assembly 23 , and the surface profile detector 24 . Before construction, the operator may store the initial information corresponding to the external wall structure of the building in the control component 25 in advance. For example, building-related parameters (eg, the shape, size, inclination, or material of the exterior walls) can be modeled and stored in the control component 25 . During the spraying process, the control component 25 compares the pre-stored initial information with the real-time scanning information to correct the spraying operation. That is to say, the control component 25 can control the operation of the lifting device 1 , the spraying component 22 and the driving component 23 after correction according to the scanning information and the pre-stored initial information, so as to realize a highly precise spraying operation. Wherein, the correction of the spraying operation can be the distance between the spray gun 220 and the outer wall (that is, the position in the third direction DR3), the path of spraying (that is, the distance in the first direction DR1 and/or the second direction DR2). position), pressure of spraying, amount of spraying, angle of spraying, and film thickness of spraying, etc., but not limited thereto.

In some embodiments, the spraying apparatus 2 may further include a housing 26 disposed on the stage 20 to cover the spraying assembly 22 , the driving assembly 23 , the surface profile detector 24 , and the control assembly located on the stage 20 25. The outer cover 26 can be used for wind protection, so as to protect the above-mentioned components from being disturbed by strong wind during high-altitude operation and reduce the operation precision.

Please also refer to FIG. 6 , which is a schematic diagram of an elastic component and an adsorption component according to an embodiment of the present application. As shown in the figures, in some embodiments, the spraying apparatus 2 may further include an elastic component 27, and the elastic component 27 is disposed on one side of the stage 20 adjacent to the area to be sprayed. One end of the elastic element 27 is disposed on the stage 20, and the other end is abutted against the outer wall of the building. For example, the elastic component 27 may include an upper roller 270 and a lower roller 271, and the upper roller 270 and the lower roller 271 are disposed on one side of the stage 20 adjacent to the area to be sprayed. When the carrier 20 is pulled and moved by the lift rope 12 , the elastic member 27 can reduce the friction between the carrier 20 and the outer wall. Alternatively, when the carrier 20 is attacked by strong wind, the elastic component 27 can also reduce the positive impact between the carrier 20 and the outer wall.

In some embodiments, the spraying apparatus 2 may further include a suction assembly 28, and the suction assembly 28 is disposed on one side of the stage 20 adjacent to the area to be sprayed. The adsorption component 28 is used to adsorb the outer wall of the building, so that the carrier 20 can be fixed on the outer wall. In some embodiments, the suction assembly 28 may be a high strength suction cup, but is not limited thereto.

Please refer to FIG. 7 , which is a flowchart of a method of using a spraying system according to an embodiment of the present application. As shown in the figure, the use of the spray system includes:

Step S1: Create initial information corresponding to the area to be sprayed. Among them, the establishment of initial information can be subdivided into: confirming the basic conditions of the building (outer layer, size, special conditions), preliminary graphic confirmation, graphic design planning, proofing simulation drawing confirmation, etc.

Step S2 : storing the initial information in the control component 25 .

Step S3: Scan the area to be sprayed by the surface profile detector 24 to obtain scanning information.

Step S4 : Send the scan information to the control component 25 .

Step S5 : After correcting the data according to the scanning information and the initial information, the control element 25 controls the driving device 13 , the driving element 23 and the spraying element 22 to operate. The operation of the driving device 13 refers to moving the lifting device 1 in the first direction DR1. The operation of the drive assembly 23 refers to stretching the lift rope 12 in the second direction DR2. The operation of the spraying assembly 22 includes moving the spray gun 220 in the first direction DR1, the second direction DR2 and/or the third direction DR3, controlling the spraying angle of the spray gun 220, controlling the supply pressure of the paint supply bucket 221 and the air pressure bucket 222, and supply, etc.

In some embodiments, the paint may include one or more of a primer, a finish, a stone varnish, and a clear topcoat. Preferably, the primer, the intermediate paint, the stone varnish and the clear topcoat can be sequentially applied to the exterior walls of the building. Among them, the stone flower color paint can be sprayed by a large-capacity pressure barrel, an airless spraying host, a high-pressure paint spraying pipe, a pressure gauge head and a spray gun equipment. Primers, intermediate coats, and clear topcoats are sprayed using a pressure-controlled spray host, high-pressure spray hoses, pressure gauge heads, and spray guns. It should be reminded that the above configuration is only an implementation aspect of the present application, and should not be regarded as a limitation of the present application.

In some embodiments, the sprayed path may be divided into three layers. The first layer occupies 50% of the paint, and its application path is one continuous spray in the vertical direction and one in the lateral direction. The second layer occupies 30% to 40% of the paint and its application path can be similar or the same as the first layer, or can be adjusted to the standard pattern. The third layer is the repair layer, which accounts for 10% to 20% of the paint. The best practice is to maintain a 10% to 20% overlap area for each layer of spray to achieve uniformity and integrity of the entire area.

In some embodiments, when the lines of the varietal paint on the exterior wall show a vertical flow phenomenon, it means that the amount of paint is too high, and the pressure of the spray gun needs to be adjusted to increase and the pressure of the supply to drop. Conversely, when the texture of the varietal paint on the exterior wall is damaged or atomized, it means that the amount of paint is too small, and it is necessary to adjust the pressure drop of the spray gun and the increase of the supply pressure.

In some embodiments, the angle between the spray gun 220 and the outer wall can also be adjusted according to actual conditions. For example, the spray angle may be between 15° and 90°. The preferred spraying angle can be 30°, 45°, 60°, 75°, 90° or a range of any combination of the above values.

To sum up, various beneficial effects can be achieved by operating the spraying system and its using method described above. For example, the pattern to be sprayed is made by professional drafters, and then handed over to the spraying system to spray automatically. As a result, thick sprayed patterns have a high degree of integrity and a very low error rate. In addition, the spraying system can continue to work during the construction time, which is more efficient than manpower that needs to rest. Finally, spray systems can reduce the use of manpower to reduce the risk of working at heights. Therefore, the present application implements a spraying device with high precision, low error rate, high efficiency and high safety and a method of using the same, so as to solve the difficulties faced in the prior art.

However, the above descriptions are only examples of the present application, and are not intended to limit the scope of implementation of the present application. For example, all equivalent changes and modifications made according to the shape, structure, characteristics and spirit described in the scope of the patent application of the present application, All should be included in the scope of the patent application of this application.
