Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a wall spraying device for buildings. Background Technology

[0002] Wall spraying is a common building decoration and protection process. It involves spraying paint or other materials onto walls to achieve multiple functions such as decoration, waterproofing, fireproofing, and insulation. Wall spraying is widely used in residential, commercial, and industrial buildings, offering advantages such as fast construction speed, uniform coverage, and strong adaptability.

[0003] Chinese patent CN112593683B discloses a "Spraying Device and Intelligent Spraying Robot for Building Decoration," which includes a foldable plate with multiple paint nozzles evenly distributed on it. The foldable plate comprises a flat section and side plates, both on which the paint nozzles are mounted. There are two flat sections, rotatably mounted. At least one side of each flat section is rotatably mounted with a side plate, and the flat section and all the side plates mounted thereon constitute a folded half-body, meaning the foldable plate comprises two folded half-bodies. The foldable plate can switch between a fully flat state, a corner spraying state, and a corner spraying state. This invention, a spraying device and intelligent spraying robot for building decoration, allows the spraying device to effectively handle large wall areas, corners, and other surfaces by switching between these states, resulting in high spraying efficiency and quality. Chinese patent disclosure CN114439194A, entitled "A Building Wall Spraying Device," includes a vertical pipe, a drain hole, an empty box, and spray heads. The vertical pipe is inserted vertically into the middle of the empty box, and a drain hole is located inside the empty box within the middle of the vertical pipe. Spray heads are connected to both ends of the vertical pipe. It also includes two sealing rings located in the middle of the vertical pipe, which respectively fit against the upper and lower sides of the empty box. Two retaining rings are also included in the middle of the vertical pipe, located outside the two sealing rings. Valves are also included at both the upper and lower ends of the vertical pipe. Two spray heads are provided, and the spray can be switched between them.

[0004] While the aforementioned patent allows for multi-nozzle spraying of corner areas, it still suffers from the following shortcomings: traditional wall spraying methods rely on the unidirectional movement (horizontal or vertical) of a single nozzle, which limits its core limitation to completing only a single layer per application. To achieve the standard coating thickness, operators must painstakingly repeat the entire spraying process. This repetitive labor not only significantly reduces construction efficiency but also makes it difficult to guarantee coating uniformity, affecting the overall spraying effect. Summary of the Invention

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: A wall spraying device for building construction mainly includes a movable component, a suspension plate 1, and a spraying component installed on the top of the wall 3. The movable component can drive the suspension plate 1 and the spraying component to move, so that the spraying component can spray different positions on the wall 3. The spraying component has three different spraying modes: it can spray horizontally alone, it can spray vertically alone, and it can use horizontal and vertical spraying in combination to achieve multi-layer spraying, which can not only ensure the uniformity of spraying, but also improve the overall spraying effect.

[0023] like Figure 1 and Figure 2As shown, a limiting track 4 extending along the extension direction of the wall 3 is fixed at the top of the wall 3, and the moving component slides on the limiting track 4; the spraying component is fixedly installed on the hanging plate 1, and several hanging ears 5 distributed at left and right intervals are fixed at the top of the hanging plate 1. The moving component is fixedly connected to the hanging ears 5 by a rope 6, so that when the moving component moves along the extension direction of the wall 3, it can drive the hanging plate 1 to move left and right by the rope 6, and the moving component can also drive the hanging plate 1 to move up and down.

[0024] Specifically, the moving component includes a second drive motor, a second lead screw, and a moving main plate. The second drive motor is mounted on the wall 3, and its output shaft is fixedly connected to the second lead screw. The moving main plate is guided and slidably mounted on the limiting rail 4, and is threadedly connected to the second lead screw so that when the second lead screw rotates, it can drive the moving main plate to slide along the extension direction of the limiting rail 4. A third drive motor and a fixing frame are mounted on the moving main plate. Two winding wheels are fixed on the output shaft of the third drive motor, and two auxiliary wheels are fixed on the fixing frame. The upper end of the rope 6 passes around the auxiliary wheels and is fixedly connected to the winding wheels so that the winding of the winding wheels can drive the rope 6 to be wound and unwound, thereby adjusting the height of the suspension plate 1.

[0025] like Figure 1 , Figures 3-5 As shown, the spraying assembly includes an upper horizontal reciprocating assembly 2, a lower horizontal reciprocating assembly 7, a horizontal spray head 8, a vertical spray head 9, and a gearbox. The upper horizontal reciprocating assembly 2 extends and is fixed to the side of the suspension plate 1 away from the wall 3 in the left-right direction. The lower horizontal reciprocating assembly 7 extends and is fixed to the side of the suspension plate 1 away from the wall 3 in the left-right direction. The upper horizontal reciprocating assembly 2 is driven by an upper mounting plate 11 that moves laterally. The horizontal spray head 8 is mounted on the upper mounting plate 11. The lower horizontal reciprocating assembly 7 is driven by a vertical mounting plate 12. The vertical spray head 9 is mounted on the vertical mounting plate 12 through a vertical reciprocating component, so that the vertical spray head 9 can move up and down reciprocally under the action of the vertical reciprocating component. The gearbox is fixed to the suspension plate 1, and a first drive motor 13 is fixed inside the gearbox.

[0026] Specifically, the upper-level lateral reciprocating assembly 2 includes an upper-level lead screw 201 and an upper-level guide rod 202 extending in the left-right direction. Both ends of the upper-level lead screw 201 and the upper-level guide rod 202 are mounted on the suspension plate 1 via upper-level support seats. In this embodiment, the upper-level support seats provide stable support for the upper-level lead screw 201 and the upper-level guide rod 202 to prevent misalignment. The output shaft of the first drive motor 13 is connected to the upper-level lead screw 201. The upper-level mounting plate 11 is fitted onto the upper-level lead screw 201 and the upper-level guide rod 202, and is threadedly connected to the upper-level lead screw 201. When the first drive motor 13 is connected to the upper-level lead screw 201, the upper-level lead screw 201 can rotate. The rotation of the upper-level lead screw 201 can cause the upper-level mounting plate 11 to move along the extension direction of the upper-level guide rod 202.

[0027] An upper-level storage box (not shown in the figure) is fixed on the upper-level mounting plate 11. The discharge end of the upper-level storage box is connected to the horizontal spray head 8 through an upper-level pipe. In this embodiment, the paint is stored in the upper-level storage box. Then, the paint in the upper-level storage box is transported to the horizontal spray head 8 through the upper-level pipe. Since the upper-level mounting plate 11 can move in the left and right direction, the horizontal spray head 8 will also move in the left and right direction to repeatedly spray the wall 3 from left to right.

[0028] The lower-level horizontal reciprocating assembly 7 includes a lower-level lead screw 701 and a lower-level guide rod 702 extending in the left-right direction. Both ends of the lower-level lead screw 701 and the lower-level guide rod 702 are mounted on the suspension plate 1 via lower-level support seats. The lower-level lead screw 701 is connected to the output shaft of the first drive motor 13 via a gearbox. When the first drive motor 13 is connected to the lower-level lead screw 701, it can drive the lower-level lead screw 701 to rotate. The vertical mounting plate 12 is fitted onto the lower-level lead screw 701 and the lower-level guide rod 702, and the vertical mounting plate 12 is threadedly connected to the lower-level lead screw 701. The vertical reciprocating component is mounted on the vertical mounting plate 12, and the vertical spray head 9 is mounted on the vertical reciprocating component. When the lower-level lead screw 701 rotates, it can drive the vertical mounting plate 12 to move in the left-right direction. The movement of the vertical mounting plate 12 can drive the vertical spray head 9 and the vertical reciprocating component to move, thereby realizing the left-right movement of the vertical spray head 9.

[0029] The vertical reciprocating component includes a telescopic device 15 extending in the vertical direction. In this embodiment, the telescopic device 15 adopts an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or the hydraulic telescopic rod are existing technologies and will not be described in detail here. The telescopic device 15 is fixed on the vertical mounting plate 12. The vertical spray head 9 is installed on the upper end of the movable section of the telescopic device 15. An infrared sensor (not shown in the figure) is installed in the gear box. When the infrared sensor detects that the first drive motor 13 is compatible with the lower lead screw 701, the telescopic device 15 can be started by the controller. The telescopic device 15 and the infrared sensor are connected by the controller signal so that the telescopic device 15 can move in the left and right directions while extending and retracting in the vertical direction.

[0030] A lower-level storage box (not shown in the figure) is fixed on the vertical mounting plate 12. The outlet of the lower-level storage box is connected to the vertical spray head 9 through the lower-level pipe. In this embodiment, the paint will be stored in the lower-level storage box. Then, the paint in the lower-level storage box will be transported to the vertical spray head 9 through the lower-level pipe. Since the vertical mounting plate 12 can move in the left and right direction, the vertical spray head 9 will also move in the left and right direction to spray the wall 3 repeatedly in the left and right directions.

[0031] like Figure 6 and Figure 7 As shown, the output shaft of the first drive motor 13 is connected to the upper-level horizontal reciprocating assembly 2 via a gearbox, so that the horizontal spray head 8 can perform horizontal reciprocating spraying independently. The output shaft of the first drive motor 13 is connected to the lower-level horizontal reciprocating assembly 7 via a gearbox, so that the vertical spray head 9 can perform horizontal reciprocating spraying independently. The output shaft of the first drive motor 13 is simultaneously connected to both the upper-level horizontal reciprocating assembly 2 and the lower-level horizontal reciprocating assembly 7 via a gearbox, so that the vertical spray head 9 and the horizontal spray head 8 cooperate to form a stacked spraying.

[0032] Specifically, the gearbox includes a housing 29, a gear sleeve 23, an upper first gear 24, an upper second gear 25, a lower first gear 26, a lower second gear 27, and a transmission gear assembly 28. In this embodiment, the transmission gear assembly 28 includes a first auxiliary gear and a second auxiliary gear. Both the first and second auxiliary gears rotate on the inner wall of the housing 29 and mesh with each other. The second auxiliary gear meshes with the lower second gear 27. When the gear sleeve 23 moves between the upper second gear 25 and the transmission gear assembly 28, it can drive the second gear 25 and the transmission gear assembly 28 to rotate. The upper lead screw 201 and the lower lead screw... The end of lever 701 near housing 29 rotates on the inner wall of housing 29; the first drive motor 13 is fixed inside housing 29, and gear sleeve 23 is connected to the output shaft of the first drive motor 13 by a guide spline and can move along the extension direction of the output shaft of the first drive motor 13; the upper first gear 24 and the upper second gear 25 are fixed to the upper lead screw 201 from left to right, and the size of the upper second gear 25 is larger than that of the upper first gear 24. When the adjusting component 30 drives the gear sleeve 23 to move to mesh with the upper first gear 24, the upper lead screw 201 can be rotated through the upper first gear 24, and the lower first gear 26 and the lower second gear 25 can rotate. Wheels 27 are fixed to the lower-level lead screw 701 at intervals from left to right. The size of the lower-level first gear 26 is smaller than that of the lower-level second gear 27. When the adjusting component 30 moves the gear sleeve 23 to mesh with the lower-level first gear 26, the lower-level lead screw 701 can be rotated through the lower-level first gear 26. The transmission gear component 28 is rotatably mounted on the housing 29. The gear sleeve 23 can mesh with the upper-level first gear 24, the lower-level first gear 26, or the upper-level second gear 25 and the transmission gear component 28. When the adjusting component 30 moves the gear sleeve 23 to mesh with the upper-level second gear 25 and the transmission gear component 28, the lower-level lead screw 701 can be rotated through the transmission gear component 28. The lower-level second gear 27 rotates. Since the size of the upper-level second gear 25 is larger than that of the lower-level second gear 27, the upper-level lead screw 201 rotates slower, while the lower-level lead screw 701 rotates faster. This is because the upper-level lead screw 201 drives the horizontal spray head 8 to move linearly left and right, while the lower-level lead screw 701 drives the vertical spray head 9 to move in a wave-like trend. In order to make the horizontal spray head 8 and the vertical spray head 9 move the same distance, the upper-level lead screw 201 rotates slower and the lower-level lead screw 701 rotates faster. An adjustment component 30 is provided inside the housing 29. The adjustment component 30 is rotatably connected to the gear sleeve 23 so that the gear sleeve 23 extends and moves along the output shaft of the first drive motor 13.

[0033] The gear sleeve 23 includes a splined cylinder 2301 that slides on the output shaft of the first drive motor 13, a primary gear 2302 fixed on the splined cylinder 2301 near the first drive motor 13, and a secondary gear 2303 fixed on the splined cylinder 2301 away from the first drive motor 13 (spline connection not shown in the figure). The size of the primary gear 2302 is larger than that of the secondary gear 2303. The adjusting component 30 is rotatably connected to the upper surface of the splined cylinder 2301. When the splined cylinder 2301 moves under the action of the adjusting component 30 until the primary gear 2302 meshes with the upper first gear 24 or the lower first gear 26, it can drive the upper lead screw 201 or the lower lead screw 701 to rotate. When the splined cylinder 2301 moves under the action of the adjusting component 30 until the secondary gear 2303 meshes with the upper second gear 25 and the transmission gear component 28, it can drive the upper second gear 25 and the transmission gear component 28 to rotate.

[0034] In this embodiment, the adjustment component 30 includes a telescopic mechanism and a long plate. A concave limiting groove is provided on the inner wall of the housing 29 for the long plate to slide. The telescopic mechanism adopts an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or hydraulic telescopic rod are existing technologies and will not be described in detail here. The movable end of the telescopic mechanism is fixedly connected to the long plate so that the long plate can move along the concave limiting groove. The end of the long plate away from the telescopic mechanism is rotatably connected to the spline cylinder 2301 so that the movement of the long plate can drive the spline cylinder 2301 to move. In this embodiment, the infrared sensor is installed on the inner wall of the housing 29 and is located between the lower first gear 26 and the lower second gear 27. When the infrared sensor detects the spline cylinder 2301, it will drive the telescopic device 15 to start through the controller.

[0035] In this embodiment, when the horizontal spray head 8 and the vertical spray head 9 work together, the vertical spray head 9 can assist the horizontal spray head 8 in spraying, so that the vertical spray head 9 can re-spray areas missed by the horizontal spray head 8.

[0036] Working Principle: First Spraying Mode: The telescopic mechanism is activated, allowing the long plate to move along the concave limiting groove. The movement of the long plate moves the splined cylinder 2301 until the primary gear 2302 meshes with the upper primary gear 24. Then, the upper primary gear 24 drives the upper lead screw 201 to rotate. The rotation of the upper lead screw 201 causes the upper mounting plate 11 to move along the extension direction of the upper guide rod 202. Since the transverse spray head 8 is mounted on the upper mounting plate 11, the transverse spray head 8 also moves left and right as the upper mounting plate 11 moves, performing repeated transverse spraying on the wall 3. Second Spraying Mode: The telescopic mechanism is activated, allowing the long plate to move along the concave limiting groove. The movement of the long plate moves the splined cylinder 2301 until the primary gear 2302 meshes with the lower primary gear 26. Then, the lower primary gear 26 drives the lower lead screw 701 to rotate. The rotation of the lower screw 701 drives the vertical mounting plate 12 to move in the left and right directions. The movement of the vertical mounting plate 12 drives the vertical spray head 9 and the vertical reciprocating component to move, so that different spray heights can be achieved by adjusting the height of the suspension plate 1. At the same time, under the action of the infrared sensor, the telescopic device 15 can be started, so that the vertical spray head 9 moves in a wave-like trend. The third spray mode: the telescopic mechanism is started, so that the long plate can move along the concave limiting groove. The movement of the long plate can drive the spline cylinder 2301 to move until the secondary gear 2303 meshes with the upper second gear 25 and the transmission gear component 28. Then, the upper screw 201 and the lower screw 701 can be rotated, so that the horizontal spray head 8 and the vertical spray head 9 can be used together to achieve multi-layer spraying, which can not only ensure the uniformity of spraying, but also improve the overall spraying effect.

[0037] In Example 2, in the structure of Example 1, the telescopic device 15 requires an infrared sensor to trigger it before it can be started, which will cause errors. In addition, the telescopic device 15 also needs to be connected to an external power source, which increases the cost.

[0038] Based on the above problems, in this embodiment, as follows: Figure 8 and Figure 9 As shown, the vertical reciprocating component may further include a reciprocating grooved cylinder 1501 extending in the vertical direction, a vertical rod 1502 extending in the vertical direction, a guide block 1503, and a transmission assembly. The lower-level lead screw 701 is connected to the reciprocating grooved cylinder 1501 through the transmission assembly, so that when the lower-level lead screw 701 rotates, it can drive the reciprocating grooved cylinder 1501 to rotate. In this embodiment, the reciprocating grooved cylinder 1501 is a cylindrical cylinder and a spiral groove formed on the cylindrical cylinder. The guide block 1503 guides and slides in the spiral groove.

[0039] Specifically, the vertical mounting plate 12 has a concave groove 17 for guiding the vertical rod 1502 to slide. The guide block 1503 is fixed on the vertical rod 1502 and slides within the groove of the reciprocating groove cylinder 1501. This allows the reciprocating groove cylinder 1501 to rotate, which in turn drives the guide block 1503 to move along the groove of the reciprocating groove cylinder 1501, thereby guiding the vertical rod 1502 to move along the concave groove 17. The vertical spray head 9 is installed at the upper end of the vertical rod 1502.

[0040] The transmission assembly includes a rack 18, a mating gear 19, a first sprocket 20, and a second sprocket 21. The rack 18 is fixed on a vertical mounting plate 12, and a fixed support is fixed on the upper part of the vertical mounting plate 12. A transmission rod 22 extending in the vertical direction is rotatably inserted into the fixed support. When the lower screw 701 rotates, it can drive the vertical mounting plate 12 to move, and the movement of the vertical mounting plate 12 can drive the mating gear 19 to move. Since the upper end of the transmission rod 22 is fixedly connected to the mating gear 19, and the mating gear 19 meshes with the rack 18, the rotation of the transmission rod 22 can drive the mating gear 19 to rotate. The lower end of the transmission rod 22 is fixedly connected to the first sprocket 20, and the lower end of the reciprocating grooved cylinder 1501 is fixedly connected to the second sprocket 21. The first sprocket 20 and the second sprocket 21 are connected by a chain drive. When the transmission rod 22 rotates, it can drive the reciprocating grooved cylinder 1501 to rotate through the first sprocket 20, the second sprocket 21, and the chain.

[0041] Compared to Embodiment 1, the advantage of this embodiment is that it saves costs and can also improve the spraying effect of the vertical spray head 9.

[0042] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is that by using three different spraying modes, adjustments can be made as needed, which not only improves work efficiency but also ensures uniform spraying and improves the overall spraying effect. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
