Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an indoor spraying equipment for building construction. Background Technology

[0002] In modern interior design, ceiling installation is a crucial step. Especially in settings seeking a minimalist, business-like style, aluminum square tube ceilings are highly favored for their unique design and aesthetic appeal. The aluminum square tube has a U-shaped channel structure, a design that is not only simple and elegant but also highly decorative. During installation, the aluminum square tube is fixed to the ceiling along the wall, with the channel opening facing outwards, forming a long, narrow structure.

[0003] Aluminum square tubes come in a variety of colors. Before installation, it's necessary to select tubes that coordinate with the wall color to enhance the ceiling's aesthetics. However, since aluminum square tube colors cannot be customized, when existing colors don't meet requirements, painting is often necessary after installation to achieve the desired visual effect. Painting requires workers to operate at heights, using handheld spray guns to coat the inner walls of the aluminum square tubes, resulting in high labor intensity and fatigue. The relatively narrow channels of the aluminum square tubes also demand a high level of skill from the workers. Furthermore, because ceilings are typically long, workers need to constantly climb and move ladders to complete the painting work, leading to low efficiency. Utility Model Content

[0004] To avoid workers having to climb to heights, reduce the technical difficulty of painting aluminum square tube ceilings, and improve work efficiency, this application provides an indoor spraying equipment for building construction.

[0005] This application provides an indoor spraying equipment for building construction, adopting the following technical solution: An indoor spraying equipment for building construction includes a trolley, an electric telescopic rod, and a spraying assembly. The lower end of the electric telescopic rod is rotatably connected to the trolley. The spraying assembly includes a cylinder, a spray pipe, and a paint bucket. A base plate is rotatably connected to one end of the cylinder. The base plate has an annular groove for the spray pipe to pass through. The upper end of the electric telescopic rod is fixedly connected to the axis of the base plate. A steering plate is fixedly connected to the inner wall of the cylinder. The steering plate is located on the side of the base plate away from the electric telescopic rod. A steering motor is fixedly connected to the base plate, and the output shaft of the steering motor is fixedly connected to the axis of the steering plate. The end of the inner wall of the cylinder away from the steering plate is fixedly connected to... There is a fixed plate, and a switching plate is rotatably connected to the inner wall of the cylinder. The switching plate is located on the side of the fixed plate away from the bottom plate and abuts against the fixed plate. The paint spraying pipe passes through the annular groove, the turning plate, and the fixed plate. The paint spraying pipe is fixedly connected to the turning plate and the fixed plate. The lower end of the paint spraying pipe is connected to the paint bucket. A switching motor is fixedly connected to the side of the fixed plate near the bottom plate. The output shaft of the switching motor passes through the fixed plate and is fixedly connected to the switching plate. A first spray head and a second spray head are symmetrically fixedly connected to the side of the switching plate away from the fixed plate. Both the first spray head and the second spray head are connected to the switching plate and are adapted to the paint spraying pipe. The first spray head faces the side away from the switching plate, and the second spray head faces the direction away from the center of the switching plate.

[0006] By adopting the above technical solution, the worker first starts the switching motor to connect the first nozzle to the paint spraying pipe, then starts the electric telescopic rod to raise the paint spraying assembly. When the paint spraying assembly is high enough to fit inside the aluminum square tube, the trolley drives the electric telescopic rod to push the paint spraying assembly into the aluminum square tube. Then, the trolley is pushed along the length of the aluminum square tube, and the first nozzle is used to spray the sides of the aluminum square tube. After the sides are sprayed, the switching motor is started to connect the second nozzle to the paint spraying pipe. At this time, the second nozzle is oriented diagonally upwards and is used to spray the top surface of the aluminum square tube. After the top surface is sprayed, the direction of the second nozzle is turned diagonally downwards by the steering motor, and the second nozzle is used to spray the bottom surface of the aluminum square tube. After all spraying is completed, the paint spraying assembly is removed from the aluminum square tube by the trolley. The electric telescopic rod drives the painting assembly to move up and down, and the switching motor can automatically switch the spray nozzles at high positions, eliminating the need for workers to climb up and manually switch nozzles. At the same time, the movement of the trolley can drive the electric telescopic rod and the painting assembly to move synchronously, achieving a complete one-time spraying of the interior of the aluminum square tube. This eliminates the need for workers to hold the spray nozzles while spraying, reducing the technical difficulty of painting aluminum square tube ceilings and improving work efficiency.

[0007] Optionally, both the first and second nozzles are flat nozzles, with the first nozzle set vertically and the second nozzle set parallel to the length direction of the cylinder.

[0008] By adopting the above technical solution, the first and second nozzles are flat nozzles, which can expand the spraying range and reduce the number of spraying times during spraying. The first nozzle is set vertically and moved by a trolley, which can achieve a complete one-time spraying of the side of the aluminum square tube. The second nozzle is set parallel to the length of the cylinder and moved by a trolley, which can achieve a complete one-time spraying of the top or bottom surface of the aluminum square tube, thus improving work efficiency.

[0009] Optionally, the trolley includes a handle, a support plate, and four casters. The lower end of the handle is fixedly connected to the support plate, and the lower end face of the support plate is fixedly connected to the four casters. A positioning frame is fixedly connected to the support plate, and a storage motor is fixedly connected to the upper end of the positioning frame. The output shaft of the storage motor passes through the positioning frame and is fixedly connected to a first gear. An electric telescopic rod is rotatably connected to the support plate, and the electric telescopic rod passes through and is fixedly connected to a second gear. The first gear and the second gear mesh.

[0010] By adopting the above technical solution, after the storage motor is started, it drives the first gear to rotate, the first gear drives the second gear to rotate, and finally the storage motor can drive the electric telescopic rod to rotate. When the equipment is not in use, the painting assembly is located on the trolley, reducing the overall footprint of the equipment, making it easier to move the equipment, and also reducing the chance of the painting assembly being bumped when the equipment is not in use. When the equipment needs to be used, the storage motor is started to rotate the electric telescopic rod and the painting assembly outward for easy use.

[0011] Optionally, the support plate is provided with a storage platform.

[0012] By adopting the above technical solution, after the equipment is used, the worker starts the storage motor to rotate the painting assembly back to the top of the trolley, adjusts the length of the electric telescopic rod, and places the painting assembly on the storage platform. This supports the painting assembly and prevents the electric telescopic rod from being subjected to a downward pull for a long time, thereby extending the service life of the equipment.

[0013] Optionally, a storage rack is fixedly connected to the side of the paint bucket near the storage table.

[0014] By adopting the above technical solution, when the equipment is not in use, the paint spray tube can be wrapped around the storage rack. The U-shaped storage rack helps to fix the position of the paint spray tube and prevent it from falling off.

[0015] Optionally, the support plate is provided with four first limiting components, each corresponding to a swivel wheel. Each first limiting component includes two first limiting slots, two first pins, and two T-shaped first limiting blocks. The first limiting slots, first pins, and first limiting blocks correspond one-to-one. The first limiting slots are all formed along the length of the support plate. The distance between two first limiting slots is the same as the width of the swivel wheel. The first limiting blocks are slidably connected in their corresponding first limiting slots. A first limiting hole, matching the first pin, is formed at the lower end of the first limiting block. The first pin is set along the width of the first limiting slot. The end of the first pin furthest from the first limiting slot passes through and is slidably connected to a first limiting piece. The lower end of the first limiting piece is fixedly connected to the support plate. The end of the first pin closest to the first limiting slot passes through and is fixedly connected to a second limiting piece. A first spring is fixedly connected between the first limiting piece and the second limiting piece, and the first pin passes through the first spring.

[0016] By adopting the above technical solution, after the first pin is inserted into the first limiting hole, the first limiting block is positioned above the support plate and does not limit the caster wheel below the support plate. When the worker needs to push the cart along the length of the support plate, the first pins of the four first limiting components are pulled away from the first limiting block, so that the first pins leave the first limiting hole and the first limiting block falls down, thus limiting the caster wheel in the width direction of the support plate, so that the cart can only move along the length of the support plate.

[0017] Optionally, the support plate is provided with four second limiting components, each corresponding to a swivel wheel. Each second limiting component includes two second limiting slots, two second pins, and two T-shaped second limiting blocks. The second limiting slots, pins, and blocks correspond one-to-one. The second limiting slots are all formed along the width of the support plate. The distance between two second limiting slots is the same as the width of the swivel wheel. The second limiting blocks are slidably connected in their corresponding second limiting slots. A second limiting hole, matching the second pin, is provided at the lower end of the second limiting block. The second pin is set along the width of the second limiting slot. A third limiting piece is slidably connected to the end of the second pin away from the second limiting slot. The lower end of the third limiting piece is fixedly connected to the support plate. A fourth limiting piece is fixedly connected to the end of the second pin near the second limiting slot. A second spring is fixedly connected between the third and fourth limiting pieces, and the second pin passes through the second spring.

[0018] By adopting the above technical solution, after the second pin is inserted into the second limiting hole, the second limiting block is positioned above the support plate and does not limit the casters below the support plate. When the worker needs to push the cart along the width of the support plate, the second pins of the four second limiting components are pulled away from the second limiting block, causing the second pins to leave the second limiting hole and the second limiting block to fall down, thus limiting the casters along the length of the support plate and allowing the cart to move only along the width of the support plate.

[0019] Optionally, a number of clips adapted to the paint spray tube are fixedly connected to the upper end of the first electric telescopic rod on the side away from the paint spraying assembly.

[0020] By adopting the above technical solution, before using the equipment, the paint spraying tube is inserted into the buckle to fix its position. After the first electric telescopic rod drives the paint spraying assembly to the height of the aluminum square tube, the paint spraying tube is unfolded. The buckle can prevent the paint spraying tube from shaking and improve the stability of the paint spraying assembly.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By using an electric telescopic rod, a painting assembly, and a steering motor, the painting assembly is raised and inserted into the aluminum square tube. Then, a trolley is pushed along the length of the aluminum square tube, and the first nozzle is used to spray the sides. After the sides are painted, the switching motor is activated to use the second nozzle to spray the top surface. After the top surface is painted, the steering motor is used to turn the second nozzle downwards, and the second nozzle is used to spray the bottom surface. After all painting is completed, the painting assembly is removed from the aluminum square tube using the trolley. This method avoids workers climbing to heights, reduces the technical difficulty of painting aluminum square tube ceilings, and improves work efficiency.

[0023] 2. By setting the first limiting component, when the worker needs to push the cart along the length of the support plate, the first pins of the four first limiting components are pulled away from the first limiting block, so that the first pins leave the first limiting hole and the first limiting block falls down, which limits the universal wheel in the width direction of the support plate, so that the cart can only move along the length of the support plate.

[0024] 3. By setting the second limiting components, when the worker needs to push the trolley along the width direction of the support plate, the second pins of the four second limiting components are pulled away from the second limiting blocks, so that the second pins leave the second limiting holes and the second limiting blocks fall down, which limits the universal wheels in the length direction of the support plate, so that the trolley can only move along the width direction of the support plate.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses an indoor spraying equipment for building construction. Example

[0033] Reference Figure 1An indoor spraying equipment for building construction includes a trolley 1, an electric telescopic rod 2, and a spraying assembly 3. The trolley 1 includes a handle 11, a support plate 12, and four casters 13. The lower end of the handle 11 is fixedly connected to the support plate 12. Workers move the trolley 1 by pushing the handle 11. The lower end of the support plate 12 is fixedly connected to the four casters 13, allowing workers to move the trolley 1 flexibly in all directions with the support of the casters 13. The electric telescopic rod 2 drives the spraying assembly 3. A storage platform 18 is placed on the support plate 12. In the initial state, the electric telescopic rod 2 is in a shortened state, and the spraying assembly 3 is placed on the storage platform 18. The storage platform 18 supports the spraying assembly 3, preventing the spraying assembly 3 from exerting a downward pulling force on the electric telescopic rod 2 for extended periods when idle, thereby extending the service life of the equipment.

[0034] Reference Figure 1 and Figure 2 A positioning frame 14 is fixedly connected to the support plate 12. A storage motor 15 is fixedly connected to the upper end of the positioning frame 14. The positioning frame 14 supports the storage motor 15. The output shaft of the storage motor 15 passes through the positioning frame 14 and is fixedly connected to the first gear 16. After the storage motor 15 is started, it drives the first gear 16 to rotate. The electric telescopic rod 2 passes through and is fixedly connected to the second gear 17. The first gear 16 meshes with the second gear 17. The rotation of the first gear 16 can drive the second gear 17 and the electric telescopic rod 2 to rotate synchronously. The electric telescopic rod 2 is rotatably connected to the support plate 12. After the storage motor 15 is started, it can drive the electric telescopic rod 2 to rotate on the support plate 12.

[0035] Reference Figure 1 and Figure 2When the equipment is needed, start the storage motor 15, which will cause the electric telescopic rod 2 to rotate the spray painting assembly 3 counterclockwise until the spray painting assembly 3 is above the storage table 18. Then, the worker controls the electric telescopic rod 2 to raise the spray painting assembly 3 to a height that can be used to spray paint the aluminum square tube, and the painting can begin. When the spray painting assembly 3 rises, the spray painting tube 32 rises synchronously. Several buckles 21 that are compatible with the spray painting tube 32 are fixedly connected to the upper end of the electric telescopic rod 2 away from the spray painting assembly 3. The worker can insert the spray painting tube 32 into the buckles 21 to fix the position of the spray painting tube 32, prevent the spray painting tube 32 from shaking, and improve the stability of the spray painting assembly 3. After the painting is finished, the storage motor 15 is restarted, which drives the electric telescopic rod 2 and the painting assembly 3 to rotate clockwise to the top of the storage platform 18. This reduces the overall footprint of the equipment and reduces the chance of the painting assembly 3 being bumped during the movement of the equipment. At the same time, the electric telescopic rod 2 drives the painting assembly 3 to descend, and finally the painting assembly 3 is placed back on the storage platform 18. When the painting assembly 3 descends, the paint pipe 32 also descends. The paint bucket 33 is fixedly connected to the storage rack 331 on the side near the storage platform 18. Workers can coil the paint pipe 32 around the storage rack 331 to fix the position of the paint pipe 32 and prevent the paint pipe 32 from falling.

[0036] Reference Figure 3 The painting assembly 3 includes a cylinder 31, a paint spray pipe 32, and a paint bucket 33. A base plate 4 is rotatably connected to one end of the cylinder 31. A first limiting groove 42, adapted to the base plate 4, is formed on the inner wall of the cylinder 31. The first limiting groove 42 limits the base plate 4 along the length of the cylinder 31. The upper end of the electric telescopic rod 2 is fixedly connected to the axis of the base plate 4. A steering plate 51 is fixedly connected to the inner wall of the cylinder 31. The steering plate 51 is located on the side of the base plate 4 away from the electric telescopic rod 2. The cylinder 31 rotates... The guide plate 51 provides support. A fixed plate 53 is fixedly connected to the end of the inner wall of the cylinder 31 away from the guide plate 51. The cylinder 31 supports the fixed plate 53. A switching plate 61 is rotatably connected to the inner wall of the cylinder 31. The switching plate 61 is located on the side of the fixed plate 53 away from the bottom plate 4 and abuts against the fixed plate 53. A second limiting groove 63 adapted to the switching plate 61 is opened on the inner wall of the cylinder 31. The second limiting groove 63 limits the switching plate 61 along the length direction of the cylinder 31.

[0037] Reference Figure 1 and Figure 3A switching motor 62 is fixedly connected to the side of the fixed plate 53 near the base plate 4. The fixed plate 53 supports the switching motor 62. The output shaft of the switching motor 62 passes through the fixed plate 53 and is fixedly connected to the switching plate 61. After the switching motor 62 starts, it drives the switching plate 61 to rotate. A first nozzle 71 and a second nozzle 72 are symmetrically fixedly connected to the side of the switching plate 61 away from the fixed plate 53. When the switching plate 61 rotates, it can drive the first nozzle 71 and the second nozzle 72 to rotate together. The first nozzle 71 and the second nozzle 72 are both flat nozzles, which can expand the spraying range and reduce the number of spraying times during spraying. The paint spray pipe 32 passes through the annular groove 41, the turning plate 51 and the fixed plate 53. The paint spray pipe 32 is fixedly connected to the turning plate 51 and the fixed plate 53. The turning plate 51 and the fixed plate 53 support the paint spray pipe 32. The lower end of the paint spray pipe 32 is connected to the paint bucket 33. During spraying, the paint is discharged from the paint bucket 33.

[0038] Reference Figure 4 The support plate 12 is provided with four second limiting components 9, each corresponding to a swivel wheel 13. Each second limiting component 9 limits the length of the swivel wheel 13. Each second limiting component 9 includes two second limiting slots 91, two second pins 92, and two T-shaped second limiting blocks 93. The second limiting slots 91, second pins 92, and second limiting blocks 93 correspond to each other. The second limiting slots 91 are all formed along the width of the support plate 12. The second limiting blocks 93 are slidably connected to their corresponding second limiting slots 91. The T-shaped crossbar of the second limiting block 93 is located above the second limiting slot 91, and its width is greater than the width of the second limiting slot 91, preventing the second limiting block 93 from slipping out of the second limiting slot 91. The second pins 92 are set along the width of the second limiting slots 91, and the lower end of the second limiting block 93 has a corresponding opening. The second limiting hole 94 is adapted to the second pin 92. After the second pin 92 is inserted into the second limiting hole 94, it can limit the second limiting block 93 in the vertical direction through the second limiting hole 94. The end of the second pin 92 away from the second limiting groove 91 is inserted and slidably connected to the third limiting piece 95. The second pin 92 can slide in the third limiting piece 95. The lower end of the third limiting piece 95 is fixedly connected to the support plate 12. The third limiting piece 95 is fixed and provides support for the second pin 92. The end of the second pin 92 near the second limiting groove 91 is inserted and fixedly connected to the fourth limiting piece 96. The fourth limiting piece 96 abuts against the support plate 12. When the second pin 92 moves, it can drive the fourth limiting piece 96 to move synchronously.

[0039] Reference Figure 1 and Figure 4A second spring 97 is fixedly connected between the third limiting plate 95 and the fourth limiting plate 96. The second pin 92 passes through the second spring 97. When the second pin 92 is inserted into the second limiting hole 94, the second spring 97 is in a compressed state. At this time, the second limiting block 93 is fixed above the support plate 12 and does not affect the movement direction of the caster wheel 13. The worker can pull the second pin 92 away from the second limiting block 93, causing the fourth limiting plate 96 to move synchronously. The fourth limiting plate 96 applies a force to the second spring 97 away from the second limiting block 93. The third limiting plate 95 applies a force to the second spring 97 in the direction of the second limiting block 93. The force in the direction of the second limiting block 93, the third limiting piece 95 and the fourth limiting piece 96 cooperate with each other to further compress the second spring 97. At the same time, the second pin 92 leaves the second limiting hole 94. Under its own weight, the second limiting block 93 falls along the second limiting groove 91 and abuts against the universal wheel 13. The second pin 92 abuts against the upper end of the second limiting block 93. The distance between the two second limiting grooves 91 is the same as the width of the universal wheel 13. The two second limiting blocks 93 cooperate to limit the universal wheel 13 in the length direction of the support plate 12, so that the trolley 1 can only move in the width direction of the support plate 12.

[0040] Reference Figure 3 and Figure 4 Both the first nozzle 71 and the second nozzle 72 are connected to the switching plate 61 and are compatible with the paint spraying pipe 32. During painting, the worker first raises the paint spraying assembly 3 to a height that allows painting of the aluminum square tube using the electric telescopic rod 2. Then, the worker pulls the second pin 92 away from the second limit block 93, causing the second pin 92 to leave the second limit hole 94. The second limit block 93 then falls, limiting the length of the support plate 12 on the caster wheel 13, thus allowing the trolley 1 (refer to...) to... Figure 1 It can only move along the width of the support plate 12. The worker pushes the cart 1 (refer to) along the width of the support plate 12. Figure 1 ), so that cart 1 (refer to Figure 1 The painting assembly 3 is driven into the aluminum square tube; the worker can adjust the vertical position of the painting assembly 3 through the electric telescopic rod 2, and the trolley 1 is fixed by the second pin 92 (see reference). Figure 1 After moving in the direction of movement, push cart 1 (refer to) Figure 1 Adjust the position of the paint spraying assembly 3 within the aluminum square tube to improve the painting effect; after the position of the paint spraying assembly 3 is determined, the worker can pull the second limiting block 93 vertically upwards. When the second limiting hole 94 moves to the position of the second pin 92, the second spring 97 extends, causing the second pin 92 to insert into the second limiting hole 94. The second limiting block 93 is then fixed above the support plate 12. The second limiting block 93 controls the trolley 1 (refer to...). Figure 1 The limiting effect of ) is released.

[0041] Reference Figure 5The support plate 12 is provided with four first limiting components 8, each corresponding to a swivel wheel 13. Each first limiting component 8 limits the width of the swivel wheel 13 within the support plate 12. Each first limiting component 8 includes two first limiting slots 81, two first pins 82, and two T-shaped first limiting blocks 83. The first limiting slots 81, first pins 82, and first limiting blocks 83 correspond one-to-one. The first limiting slots 81 are all formed along the length of the support plate 12. The first limiting blocks 83 are slidably connected to their corresponding first limiting slots 81. The T-shaped crossbar of the first limiting block 83 is located above the first limiting slot 81, and its width is greater than the width of the first limiting slot 81, preventing the first limiting block 83 from slipping out of the first limiting slot 81. The first pins 82 are set along the width of the first limiting slot 81, and the lower end of the first limiting block 83 has a corresponding opening. The first limiting hole 84 is adapted to the first pin 82. After the first pin 82 is inserted into the first limiting hole 84, it can limit the first limiting block 83 in the vertical direction through the first limiting hole 84. The end of the first pin 82 away from the first limiting groove 81 is inserted and slidably connected to the first limiting piece 85. The first pin 82 can slide in the first limiting piece 85. The lower end of the first limiting piece 85 is fixedly connected to the support plate 12. The first limiting piece 85 is fixed and supports the first pin 82. The end of the first pin 82 near the first limiting groove 81 is inserted and fixedly connected to the second limiting piece 86. The second limiting piece 86 abuts against the support plate 12. When the first pin 82 moves, it can drive the second limiting piece 86 to move synchronously.

[0042] Reference Figure 1 and Figure 5 A first spring 87 is fixedly connected between the first limiting plate 85 and the second limiting plate 86. A first pin 82 passes through the first spring 87. When the first pin 82 is inserted into the first limiting hole 84, the first spring 87 is in a compressed state. At this time, the first limiting block 83 is fixed above the support plate 12 and does not affect the movement direction of the caster wheel 13. The worker can pull the first pin 82 away from the first limiting block 83, causing the second limiting plate 86 to move synchronously. The second limiting plate 86 applies a force to the first spring 87 away from the first limiting block 83, and the first limiting plate 85 applies a force to the first spring 87 in the direction of the first limiting block 83. The force applied to the first limiting block 83 causes the first limiting piece 85 and the second limiting piece 86 to cooperate, further compressing the first spring 87. At the same time, the first pin 82 leaves the first limiting hole 84, and the first limiting block 83 falls along the first limiting groove 81 under its own weight, abutting against the universal wheel 13. The first pin 82 abuts against the upper end of the first limiting block 83. The distance between the two first limiting grooves 81 is the same as the width of the universal wheel 13. The two first limiting blocks 83 cooperate to limit the width of the universal wheel 12, so that the trolley 1 can only move along the length of the support plate 12.

[0043] Reference Figure 3 and Figure 5 In the initial state, the first nozzle 71 is connected to the paint spray pipe 32, and the first nozzle 71 faces away from the switching plate 61, allowing for painting of the side of the aluminum square tube. Subsequently, the worker pulls the first pin 82 away from the first limiting block 83, causing the first pin 82 to leave the first limiting hole 84. The first limiting block 83 then falls, limiting the width of the support plate 12 on the caster wheel 13, thus allowing the trolley 1 (refer to...) to... Figure 1 It can only move along the length of the support plate 12. The worker pushes the cart 1 (refer to) along the length of the support plate 12. Figure 1 This causes the first spray head 71 to move. The first spray head 71 is set vertically, which can achieve complete spraying of the side of the aluminum square tube in one go, thus improving work efficiency.

[0044] Reference Figure 3 and Figure 5 After the side spraying is completed, the worker starts the switching motor 62, which drives the first spray head 71 and the second spray head 72 to rotate synchronously with the switching plate 61. The second spray head 72 faces away from the center of the switching plate 61, so that the second spray head 72 is connected to the paint spray pipe 32. At this time, the second spray head 72 is facing obliquely upward, and the second spray head 72 is set parallel to the length direction of the cylinder 31, which can realize the spraying of the top surface of the aluminum square tube. The worker can pull the first limiting block 83 vertically upward to release the first limiting block 83 from the trolley 1 (refer to Figure 1 The limiting block 83 acts as a limiter, thereby adjusting the position of the second nozzle 72 within the aluminum square tube. After the position of the second nozzle 72 is adjusted, the worker repeats the operation of pulling the first pin 82, so that the first limiting block 83 limits the universal wheel 13 in the width direction of the support plate 12, and then pushes the trolley 1 (refer to) along the length direction of the support plate 12. Figure 1 ), cart 1 (refer to) Figure 1 This drives the second nozzle 72 to move, enabling a one-time complete spraying of the top surface of the aluminum square tube.

[0045] Reference Figure 1 and Figure 3A steering motor 52 is fixedly connected to the base plate 4. The output shaft of the steering motor 52 is fixedly connected to the steering plate 51. Since the base plate 4 is rotatably connected to the cylinder 31, the steering motor 52 can drive the cylinder 31, the fixed plate 53, the switching plate 61, the first spray head 71, and the second spray head 72 to rotate synchronously after starting. The base plate 4 has an annular groove 41 for the paint spray pipe 32 to pass through, and the paint spray pipe 32 can also rotate synchronously with the cylinder 31. After the sides and top of the aluminum square tube are painted, the worker starts the steering motor 52, so that the orientation of the second spray head 72 changes to oblique downward. Then the worker pushes the trolley 1, and the trolley 1 drives the second spray head 72 to move, which can achieve a complete one-time painting of the bottom surface of the aluminum square tube. After the painting is finished, the worker pulls the first limit block 83 upward (refer to...). Figure 5 The limiting effect on the trolley 1 is released, and then the trolley 1 and the painting assembly 3 are moved out of the aluminum square tube. The electric telescopic rod 2 is shortened, and the storage motor 15 drives the electric telescopic rod 2 and the painting assembly 3 to rotate counterclockwise to the storage platform 18, completing the storage of the painting assembly 3. During the painting process, workers no longer need to climb high and hold the spray nozzle to spray the aluminum square tube, reducing the technical difficulty of painting the aluminum square tube ceiling. The positions of the first spray nozzle 71 and the second spray nozzle 72 can be adjusted by the trolley 1 and the electric telescopic rod 2, without the need for workers to climb high. At the same time, workers can switch the first spray nozzle 71 and the second spray nozzle 72 by turning on the switching motor 62, and turn on the steering motor 52 to adjust the orientation of the second spray nozzle 72, thereby achieving spraying of the sides, top, and bottom of the aluminum square tube without the need to climb high and manually switch, or lower the painting assembly 3 for replacement, thus improving the efficiency of the painting work.

[0046] The implementation principle of an indoor spraying equipment for building construction according to an embodiment of this application is as follows: the position of the spraying assembly 3 inside the aluminum square tube is adjusted by the electric telescopic rod 2 and the trolley 1; the first spray head 71 and the second spray head 72 are switched by the switching motor 62, so that the spraying assembly 3 can spray the side and top surfaces of the aluminum square tube; the orientation of the second spray head 72 is adjusted by the steering motor 52, so that the spraying assembly 3 can spray the bottom surface of the aluminum square tube. The first limiting assembly 8 can limit the width of the support plate 12 by the universal wheel 13, so that the trolley 1 can only move along the length of the support plate 12; the second limiting assembly 9 can limit the length of the support plate 12 by the universal wheel 13, so that the trolley 1 can only move along the width of the support plate 12; the worker can flexibly adjust the limiting direction of the trolley 1 according to the actual situation to achieve precise spraying of the aluminum square tube.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
