Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and specifically relates to a spraying device for exterior wall decoration. Background Technique

[0002] After a building is completed, in order to prevent the exterior wall from being exposed to wind, sun, rain, abrasion, and corrosion for a long time, it is necessary to use a spraying device to spray paint on the surface of the building. The paint can not only protect the surface of the object to be painted from erosion by light, oxygen, chemical substances, solvents, etc. from the outside, but also improve the service life of the coated object.

[0003] During the spraying process of the paint, the method is manual spraying. When a worker holds the spraying device at a high altitude to spray the paint, the worker needs to hold the spraying device for a long time, which causes soreness in the arm. This not only makes the spraying thickness uneven, but also easily causes safety hazards, and the efficiency of manual spraying is low. For this reason, we propose a spraying device for exterior wall decoration.

[0004] Combining the above problems, we will find that the existing spraying devices for exterior wall decoration on the market are difficult to avoid the above-mentioned problems simultaneously during use. And even if they can be solved, they need to be solved by cooperating with external tools, thus unable to achieve the desired effect. Therefore, we propose a spraying device for exterior wall decoration. Summary of the Invention

Material conveying branch pipes 17 arranged at equal distances are fixedly communicated with the material conveying pipe 16. The pressure cylinder 11 is connected with a spraying mechanism 2;

[0034] The spraying mechanism 2 includes a spraying protection unit 21. The spraying protection unit 21 is located outside the pressure cylinder 11 and is used for protective spraying on the wall surface.

[0035] As a further limitation of the spraying mechanism 2 of the present invention, the spraying protection unit 21 includes two side baffles 2101. The bottoms of the two side baffles 2101 are fixedly installed at both ends of the installation box 2102. Sliding grooves 2103 are provided on the edges of the same side of the two side baffles 2101 and the installation box 2102. A protection plate 2105 is slidably connected inside the sliding grooves 2103. On one edge side of the protection plate 2105 inside the sliding grooves 2103, two groups of telescopic springs 2104 are fixedly connected. The number of each group of telescopic springs 2104 is ten. One end of the telescopic spring 2104 away from the protection plate 2105 is fixedly connected to the inner side wall of the sliding groove 2103. A plurality of fixedly arranged fixing frames 2107 are fixedly installed on the bottom surface of the protection plate 2105. A rolling frame 2108 is fixedly connected to the fixing frame 2107. A fixed shaft 2109 is rotatably connected to the rolling frame 2108. A rolling wheel 2110 is fixedly connected to the fixed shaft 2109. The rolling wheel 2110 is rotatably connected inside the rolling frame 2108; by setting the spraying protection unit 21, it is ensured that the spraying nozzle 2223 maintains an appropriate spraying distance from the wall, enabling the spraying device to evenly spray the wall surface, and protecting and collecting the dripping paint during spraying, avoiding paint pollution of other positions and paint waste, and improving the spraying effect and efficiency of the spraying device;

[0036] A wear-resistant strip 2106 is fixedly connected to the edge side of the protection plate 2105 away from the telescopic spring 2104. The material of the wear-resistant strip 2106 is ultra-high molecular plastic. The fixing frame 2107 is fixedly connected to the bottom of the wear-resistant strip 2106. The wear-resistant strip 2106 has characteristics such as scratch resistance, aging resistance, high and low temperature resistance, and friction resistance. The wear-resistant strip 2106 can extend the service life of the protection plate 2105;

[0037] A fixed disk 2111 is fixedly installed on the side of the rolling frame 2108 away from the wear-resistant strip 2106. The outer surface of each fixed disk 2111 is fixedly connected to the bottom surface of the fixing frame 2107; by using the fixed disk 2111 fixed between the rolling frame 2108 and the fixing frame 2107, the stability of the rolling frame 2108 and the fixing frame 2107 is improved, thereby improving the stability of the spraying device moving along the wall surface.

[0038] The specific implementation method is as follows: When the spraying device sprays paint on the outer facade of a building wall, the driving device installed on the roof is used to move the spraying device along the outer facade of the building wall for spraying. First, the spraying device is lowered outside the outer facade of the building wall. The wear-resistant strip 2106 fixed to one side of the protective plate 2105 contacts the outer facade of the wall. The protective plate 2105 slides along the sliding groove 2103. There are two groups of telescopic springs 2104 in the sliding groove 2103. By using the telescopic springs 2104, the wear-resistant strip 2106 is in close contact with the outer facade of the wall. A plurality of fixing frames 2107 are fixed to the bottom surface of the protective plate 2105, enabling the rolling frame 2108 to be fixed to the inner wall of the fixing frame 2107. Thus, the rolling wheel 2110 rotates inside the rolling frame 2108 through the fixed shaft 2109. Furthermore, by using the rolling of the rolling wheel 2110 on the outer facade of the building wall, the stability of the protective plate 2105 is improved, ensuring that the spraying nozzle 2223 maintains an appropriate spraying distance from the wall, enabling the spraying device to evenly spray the wall surface, and protecting and collecting the paint dripping during spraying, avoiding paint pollution of other positions and paint waste, and improving the spraying effect and efficiency of the spraying device.

[0039] Please refer to Figures 1-9 , as a further limitation of the spraying mechanism 2 of the present invention, the spraying mechanism 2 further includes a spraying control unit 22. The spraying control unit 22 is located on one side of the spraying protection unit 21, and the spraying control unit 22 is used for evenly spraying the wall surface;

[0040] The spraying control unit 22 includes fixed boxes 2201 arranged at equal distances. The fixed boxes 2201 are fixedly connected to the rolling frame 2108. One end of the fixed shaft 2109 is rotatably connected inside the fixed box 2201. The end of the fixed shaft 2109 away from the rolling wheel 2110 is fixedly connected with a first bevel gear 2202. A driving telescopic rod 2203 is rotatably connected to the fixed box 2201. One end of the driving telescopic rod 2203 inside the fixed box 2201 is fixedly connected with a second bevel gear 2205. The first bevel gear 2202 and the second bevel gear 2205 are correspondingly meshed. A gear box 2207 is fixedly connected inside the installation box 2102. The gear box 2207 is provided with positioning holes 2208 arranged at equal distances. The driving telescopic rods 2203 are rotatably installed in the positioning holes 2208 one by one. Inside the gear box 2207, auxiliary shafts 2209 arranged at equal distances and output shafts 2212 arranged at equal distances are rotatably connected. The number of driving telescopic rods 2203, the number of auxiliary shafts 2209, and the number of output shafts 2212 are the same. A driving gear 2206 is fixedly installed on the driving telescopic rod 2203. A transmission gear 2210 is fixedly installed on the auxiliary shaft 2209. The transmission gear 2210 and the driving gear 2206 are correspondingly meshed one by one. An output gear 2211 is fixedly installed on the output shaft 2212. The output gear 2211 and the transmission gear 2210 are correspondingly meshed one by one. Spraying control boxes 2222 arranged at equal distances are fixedly installed on the inner wall of the installation box 2102. The number of spraying control boxes 2222 is the same as the number of output shafts 2212. A spraying nozzle 2223 is installed on one side of the spraying control box 2222 close to the wear-resistant strip 2106. The lower end of the material conveying branch pipe 17 is communicated with a lower bottom pipe 2214. The end of the output shaft 2212 penetrates through the lower bottom pipe 2214 to the inside of the spraying control box 2222. The end of the output shaft 2212 is fixedly connected with a rotation control shaft 2216. The rotation control shaft 2216 is provided with telescopic holes 2217 arranged at equal distances. A rotation sliding rod 2218 is fixedly inserted into the telescopic holes 2217. The end of the rotation sliding rod 2218 away from the rotation control shaft 2216 is fixedly connected with a stop block 2220. The stop block 2220 is slidably connected inside the spraying control box 2222. A sliding block 2219 is sleeved on the rotation sliding rod 2218. One side of the sliding block 2219 away from the rotation control shaft 2216 contacts the stop block 2220. A tension spring 2221 is sleeved on the rotation sliding rod 2218. One end of the tension spring 2221 abuts against the sliding block 2219, and the other end of the tension spring 2221 is fixedly connected to the inner wall of the telescopic hole 2217. By setting the spraying control unit 22, the rotation of the rolling wheel 2110 rolling on the wall surface is used to adjust the shielding area of the output hole of the lower bottom pipe 2214 by the sliding block 2219, so that the moving speed of the spraying device is positively correlated with the amount of the sprayed paint, thereby enabling the paint to be evenly sprayed on the wall surface;

[0041] A first bearing 2204 is fixedly connected to each driving telescopic rod 2203. One side of the outer ring of the first bearing 2204 is fixedly connected to the outer wall of the fixed box 2201. A second bearing 2213 is fixedly connected to the output shaft 2212. One side of the outer ring of the second bearing 2213 is fixedly connected to the outer wall of the gear box 2207. The first bearing 2204 improves the stability of the rotation of the driving telescopic rod 2203 inside the fixed box 2201, and the second bearing 2213 improves the stability of the rotation of the output shaft 2212 inside the gear box 2207.

[0042] A sealing bearing 2215 is fixedly connected to the output shaft 2212. One side of the outer ring of the sealing bearing 2215 is fixedly connected to the lower bottom pipe 2214. The sealing bearing 2215 is fixedly connected at the internal connection where the output shaft 2212 extends into the lower bottom pipe 2214, so that the contact position between the output shaft 2212 and the lower bottom pipe 2214 is sealed, preventing the leakage of paint from this position.

[0043] The specific implementation of this embodiment is as follows: When the spraying device sprays the wall surface, the rolling wheel 2110 rolls on the outer surface of the building wall, causing the fixed shaft 2109 to rotate inside the fixed box 2201, thereby driving the rotation of the first bevel gear 2202 at one end of the fixed shaft 2109. Since the first bevel gear 2202 meshes with the second bevel gear 2205, its transmission direction is changed, and the driving telescopic rod 2203 can be driven to rotate inside the fixed box 2201 and the positioning hole 2208. Then, the driving gear 2206 at one end of the driving telescopic rod 2203 is used to mesh with the transmission gear 2210 to drive its rotation, causing the auxiliary shaft 2209 to rotate inside the gear box 2207. The transmission gear 2210 meshes with the output gear 2211 to drive the output shaft 2212 to rotate inside the gear box 2207. The output shaft 2212 extends to one side of the gear box 2207 and passes through the lower bottom pipe 2214 into the spraying control box 2222. The paint in the lower bottom pipe 2214 flows into the spraying nozzle 2223 through the spraying control box 2222 and is sprayed out, thus completing the spraying of the wall surface. The output shaft 2212 drives the rotation control shaft 2216 to rotate inside the spraying control box 2222, causing the sliding block 2219 to slide along the rotating slide rod 2218 under the action of centrifugal force until the sliding block 2219 contacts the stop block 2220. As the rolling speed of the rolling wheel 2110 increases, the output hole of the lower bottom pipe 2214 is opened to the maximum, and the amount of paint sprayed by the spraying nozzle 2223 reaches the maximum. When the rolling speed of the rolling wheel 2110 decreases, the sliding block 2219 gradually approaches the rotation control shaft 2216 under the pulling force of the tension spring 2221 until the rolling of the rolling wheel 2110 stops, causing the multiple sliding blocks 2219 to contact the rotation control shaft 2216 to form a whole, thereby closing the output hole of the lower bottom pipe 2214 and stopping the spraying nozzle 2223 from spraying paint.

[0044] Please refer to Figures 1-9, as a further limitation of the spraying mechanism 2 of the present invention, a carrying mechanism 3 is provided outside the spraying protection unit 21. The carrying mechanism 3 is used in cooperation with the spraying mechanism 2 and is configured to carry a spraying device to spray the wall surface;

[0045] The carrying mechanism 3 includes four lifting rods 302. Two lifting rods 302 are grouped together and are respectively fixedly connected to two side baffles 2101. A connecting cross bar 301 is fixedly connected between the upper ends of the two lifting rods 302 located on the same side baffle 2101. A connecting frame 306 is directly fixedly connected between the two side baffles 2101. The pressure cylinder 11 and two material storage cylinders 13 are fixedly connected to a reinforcing frame 307. By providing the carrying mechanism 3, cooperating with the spraying protection unit 21 and the spraying control unit 22, and using a driving device arranged on the roof, the driving device being a crane that outputs a lifting force, connecting the output end of the driving device to the four lifting rods 302, the spraying device is driven by the driving device to move along the wall surface and spray the wall surface, improving the spraying effect and efficiency of the spraying device;

[0046] A right side plate 303 and a left side plate 304 arranged in parallel are installed between the two side baffles 2101. The right side plate 303 and the left side plate 304 are respectively fixedly connected to the lifting rods 302 at their ends. The two connecting frames 306 and the reinforcing frame 307 are respectively fixedly connected to the left side surface of the right side plate 303 and the left side plate 304. By using the right side plate 303 and the left side plate 304 fixed to one side of the lifting rods 302 and connecting the right side plate 303 and the left side plate 304 through the two connecting frames 306 and the reinforcing frame 307, the pressure cylinder 11 and the two material storage cylinders 13 are connected to the four lifting rods 302, thereby stably carrying the main body of the spraying device;

[0047] A lower bottom plate 305 is fixedly connected to the bottom surface of the right side plate 303 and the bottom of the left side plate 304. The lower bottom plate 305 is fixedly connected to the inner wall of the installation box 2102. The discharging end of each material conveying branch pipe 17 penetrates to the bottom of the lower bottom plate 305. By means of the lower bottom plate 305 fixed to the bottom surfaces of the right side plate 303 and the left side plate 304, the stability of the carrying frame is improved.

[0048] The specific implementation mode of this embodiment is as follows: When the spraying device sprays paint on the wall surface, a hanging basket is formed by using the side baffle 2101, the right side plate 303, the left side plate 304 and the lower bottom plate 305. A fixed structure is formed through the connecting frame 306 and the reinforcing frame 307, so that the main body of the spraying device of the pressure cylinder 11 and the two material storage cylinders 13 is fixedly installed inside the hanging basket. And by manually operating the driving device that drives the movement of the spraying device, the output end of the driving device is connected to the connecting cross bar 301 and the lifting rods 302 through ropes, thereby stably using the driving device to drive the hanging basket to pull the spraying device to move, improving the spraying effect and efficiency of the spraying device.
