Therefore, the research and application of automated wall painting equipment has become a hot technology in the construction industry.

[0003] Existing automated wall painting devices use rollers to paint walls. However, there is a 90-degree angle between the top of the wall side and the top wall. Since the rollers are circular, it is difficult to paint the corner area at the top of the wall. This 90-degree angle is usually an area that needs special attention during construction. The inability to cover this corner area requires subsequent manual intervention, which increases the complexity and cost of construction and reduces the convenience and efficiency of automated operation. Summary of the Invention

This device can paint areas that the roller has not yet reached, thus improving the quality of the work.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of an automatic wall painting device for building construction. Example

[0024] Combination Figures 1-3 As shown, the present invention provides an automatic wall painting device for building construction, including a base 100 as the carrier of the entire device, a frame 101 fixedly connected to the base 100, and a coating mechanism 200 for painting the wall surface on the base 100, which can paint the upper part of the wall surface, reduce the number of times scaffolding is erected or ladders are used, thereby improving construction efficiency.

[0025] The painting mechanism 200 includes a load-bearing plate 204 that can be raised and lowered on the frame 101. A roller 2051 is provided on one side of the load-bearing plate 204. A transmission component 205 for deflecting the roller 2051 is provided on the base 100. The load-bearing plate 204 drives the roller 2051 to rise. When it reaches a certain height, the roller 2051 deflects and extends forward, thereby extending the painting height so that the upper part of the wall can also be painted.

[0026] Specifically, the transmission assembly 205 includes a transmission frame 2057 fixed to the load-bearing plate 204, a transmission shaft 2058 rotatably mounted on the transmission frame 2057, a connecting plate 2059 fixed to the transmission shaft 2058, a U-shaped frame 2052 on one side of the connecting plate 2059, and a roller 2051 rotatably mounted on the U-shaped frame 2052. After rising above the wall, the transmission shaft 2058 drives the connecting plate 2059 to rotate, and the connecting plate 2059 drives the U-shaped frame 2052 to deflect. The roller 2051 moves with the U-shaped frame 2052. Without increasing the overall height of the equipment, it can paint the upper part of the wall. By extending the painting height, it can cover a higher area above the wall, thereby completing more paint application in one operation and improving construction efficiency.

[0027] Furthermore, the base 100 is equipped with multiple casters at its bottom, making it easier for staff to move the equipment and paint other areas.

[0028] As can be seen from the examples, the machine can maintain a consistent application force and speed when painting the upper part of the wall, which helps to improve the uniformity and quality of the coating. Example

[0029] Combination Figures 4-5 As shown, based on Embodiment 1, load-bearing plates 2065 are fixed to both sides of the connecting plate 2059. A limiting strip 2066 that is slidably connected to the load-bearing plate 2065 is fixed to the U-shaped frame 2052. A protective cover 2053 located outside the roller 2051 is fixed to the U-shaped frame 2052. A stop block is fixed to the end of the limiting strip 2066. A spring a2067 is fixed between the U-shaped frame 2052 and the load-bearing plate 2065. The wall surface and the roller 2051 are in a close contact state, while the spring a2067 is in a compressed state. When the roller 2051 deflects upward, the distance between the roller 2051 and the wall surface will change. The spring a2067 pushes the U-shaped frame 2052 to move towards the wall surface, so that the roller 2051 can always be in contact with the wall surface, thus realizing the painting operation.

[0030] Specifically, a rotating shaft 2069 is rotatably mounted on the protective cover 2053. A limit frame 2072 is fixedly connected to the rotating shaft 2069. A brush 2074 is slidably connected to one side of the limit frame 2072. A spring b2073 is fixed between the brush 2074 and the inner wall of the limit frame 2072. A spur gear b2070 is mounted on the rotating shaft 2069. A rack b2071 corresponding to the spur gear b2070 is fixedly connected to the connecting plate 2059. Because there is a 90-degree angle between the top of the side wall and the top wall, and the roller 2051 is circular, a part of the wall is difficult to paint. When the connecting plate 2059 drives the roller 2051 to deflect upward, the spring... A2067 pushes the U-shaped frame 2052 forward, and the spur gear B2070 moves with the protective cover 2053 on the U-shaped frame 2052. Then, the spur gear B2070 meshes with the rack B2071, driving the rotating shaft 2069 to rotate. The limiting frame 2072 deflects with the rotating shaft 2069. At the same time, the limiting frame 2072 drives the brush 2074 to deflect upward, and the spring B2073 pushes the brush 2074 to move towards the wall. Then, the areas that the roller 2051 did not reach can be painted. The full coverage of the wall and the automated operation can improve the consistency and accuracy of the construction, reduce the occurrence of missed brushing and repeated brushing, and thus improve the quality of the work.

[0031] As can be seen from the embodiments, it can cover the 90-degree angle between the top of the wall and the ceiling, ensuring the paint application on the entire wall surface, thereby improving the integrity and aesthetics of the construction. Example

[0032] Combination Figure 4 and Figure 5As shown, based on Embodiment 1, a connecting shaft 2061 is rotatably mounted on the load-bearing plate 204. A spur gear a2064 is fitted onto the connecting shaft 2061. A rack a2062 corresponding to the spur gear a2064 is provided on the frame 101. A worm gear 2063 is fixedly connected to the connecting shaft 2061. A worm wheel 2060 meshing with the worm gear 2063 is fixedly connected to the transmission shaft 2058. The load-bearing plate 204 drives the roller 2051 to paint upwards on the wall. The spur gear a2064... The meshing of 064 and rack a2062 causes the connecting shaft 2061 to rotate. The worm 2063 rotates with the connecting shaft 2061, and the worm 2063 drives the transmission shaft 2058 to rotate through the worm wheel 2060. Subsequently, the transmission shaft 2058 drives the roller 2051 to deflect upward through the connecting plate 2059, thereby enabling painting of the upper part of the wall and extending the painting height. This reduces the need to build temporary supports or use other high-altitude work equipment, saving time and costs.

[0033] Specifically, the frame 101 is fixedly equipped with an electric telescopic rod 2068 for adjusting the deflection position of the roller 2051 according to the wall height. The rack a2062 is fixedly connected to the free end of the electric telescopic rod 2068. When the height of the wall changes, the electric telescopic rod 2068 starts to adjust the position of the rack a2062 according to the wall height. It can be used to paint walls of different heights and can adapt to walls of different heights without replacing equipment or adjusting other parts, thus improving the flexibility and adaptability of the equipment.

[0034] As can be seen from the embodiment, an infrared camera is also provided on one side of the device, which can measure the height of the wall and then control the electric telescopic pole 2068. Without the need for manual adjustment or replacement of the equipment, it can quickly and accurately adapt to walls of different heights, thus improving construction efficiency. Example

[0035] Combination Figures 3-6 As shown, based on Embodiment 1, a motor 201 is fixedly mounted on the base 100, and a screw 203 is fixedly connected to the output end of the motor 201. The screw 203 is rotatably connected to the frame 101, and the load-bearing plate 204 is threadedly connected to the screw 203. A slide rod 202 is also fixedly connected to the frame 101, and the load-bearing plate 204 is slidably connected to the slide rod 202. When the motor 201 is started, it drives the screw 203 to rotate. The rotation of the screw 203 causes the load-bearing plate 204 to rise and fall. Using the motor 201 as a single power source can reduce the assembly cost of the equipment.

[0036] Specifically, a material box 102 containing paint is placed on the base 100, and a pump body 103 is fixedly mounted on the base 100. The end of the pump body 103 is connected to the inside of the material box 102 through a pipe. A main pipe 2054 is fixedly connected to the protective cover 2053, and multiple branch pipes 2056 for conveying paint are fixedly connected to the bottom of the main pipe 2054. The pump body 103 is connected to the main pipe 2054 through the pipe. When the pump body 103 is started, the paint is conveyed through the pipe to the area below the protective cover 2053. The paint falls onto the roller 2051, and the roller 2051 rotates to evenly apply the paint to it, which helps to improve the painting quality of the wall surface.

[0037] Furthermore, a baffle 2055 is fixed to the bottom of the protective cover 2053 and fits against the roller 2051 to prevent paint from flowing out. The baffle 2055 can block the paint and prevent it from flowing away.

[0038] As can be seen from the above embodiments: the worker moves the equipment to the front of the wall, then locks the bottom rollers, and the roller 2051 is in contact with the wall. The spring a2067 is in a compressed state. Then the motor 201 starts and drives the screw 203 to rotate. The rotation of the screw 203 causes the load plate 204 to rise, and the roller 2051 rotates along the wall to paint the wall. When it moves to the top, the spur gear a2064 and the rack a2062 mesh to make the connecting shaft 2061 rotate. The worm gear 2063 rotates with the connecting shaft 2061. The worm gear 2063 drives the transmission shaft 2058 to rotate through the worm wheel 2060. Then the transmission shaft 2058 drives the roller 2051 to deflect upward through the connecting plate 2059, so that the upper part of the wall can be painted. Then the roller 2051 returns to its original position downward.
