There are two sets of winding wheels 32, and one end of each set of winding wheels 32 is fixed with the transmission wheel 36. The two transmission wheels 36 are driven by the transmission belt 37.

[0029] It is convenient to fix the positioning frame 51 on the side wall at the bottom end of the building main body 6, so that the positioning frame 51 plays a role in supporting and restricting. Through the operation of the third motor 52, the second lead screw 54 can drive the positioning frame 51 to slide on the positioning rod 53, thereby adjusting the position of the restricting frame 72.

[0030] In the specific implementation process, as Figure 3 and Figure 4 shown, the flow splitting structure 8 further includes a flow splitting pipe 81 and a fixed shaft 82. One end of the flow splitting pipe 81 is communicated with the side wall at one end of the guiding and conveying pipe 1.

It flows into the inside of the roller shaft 26 from the opening at its bottom end, and is then absorbed by the painting roller 23 through the through holes provided on its side wall, and then painted on the wall.

[0032] The working principle of the painting equipment for building wall decoration provided by the present utility model is as follows:

[0033] During use, first fix the positioning frame 51 on the side wall at the bottom end of the building body 6, then install and fix the limiting frame 41 on the top surface of the building body 6 according to the position of the positioning frame 51, so that the positions of the second lead screw 54 and the positioning rod 53 installed between the positioning frames 51 correspond to the positions of the first lead screw 44 and the limiting rod 43 installed between the limiting frames 41. Then, hoist the outer shell 21 with the side of the fixed block 24 facing outwards on the limiting frame 41 through the steel cable 33, so that the painting roller 23 abuts against the side wall of the building body 6. Adjust the position of the outer shell 21 by winding and releasing the steel cable 33 by the reel 32. Then, respectively sleeve the two ends of the two groups of limiting frames 72 on the side walls of the first lead screw 44 and the limiting rod 43, so that the first lead screw 44 and the limiting rod 43 are supported and limited by the limiting frames 72. Sleeve the two ends of the other two groups of limiting frames 72 on the side walls of the second lead screw 54 and the positioning rod 53 respectively, so that the second lead screw 54 and the positioning rod 53 are supported and limited by the limiting frames 72. And a connecting pipe 35 is supported and fixed between the corresponding two groups of limiting frames 72. And two of the connecting pipes 35 are threadedly connected to the corresponding first lead screw 44 and the second lead screw 54, and the other two connecting pipes 35 are slidably connected to the corresponding positioning rod 53 and the limiting rod 43, so that the positions of the first lead screw 44 and the second lead screw 54 are symmetric up and down. Then, respectively fix the two limiting ropes 71 to the two groups of limiting frames 72 in an up-and-down connection state, adjust the position of the limiting ropes 71 so that they abut against the side wall of the first pulley 25, and then adjust the length of the limiting ropes 71 to make the limiting ropes 71 taut. Further, the limiting ropes 71 squeeze the outer shell 21 through the first pulley 25, and further the outer shell 21 squeezes the positioning frame 22, so that the spring 27 is in a certain degree of compressed state, and the painting roller 23 is in a squeezed state and abuts against the side wall of the building body 6. Then, connect the first motor 31 to an external power source, so that the first motor 31 drives the reel 32 to rotate, and further the reel 32 winds and releases the steel cable 33, driving the outer shell 21 to move up and down, and further the painting roller 23 rolls on the side wall of the building body 6. Connect the other end of the conveying pipe 1 to a feeding pump, and the length of the conveying pipe 1 can adapt to the maximum degree of movement of the outer shell 21, so that the paint is transported through the conveying pipe 1, and then is branched and conveyed to the interiors of the two painting rollers 23 by the shunt pipe 81. Under the extrusion of the building body 6 and its own rolling, the paint is applied to the side wall of the building body 6. After one group of paint is applied, connect the second motor 42 and the third motor 52 to an external power source, so that the two motors run synchronously.Furthermore, the first lead screw 44 and the second lead screw 54 are synchronously rotated, so that the four upper and lower limiting frames 72 are synchronously moved, and the positions of the reel 32 and the housing 21 are laterally adjusted, so that the side wall of another group of the building main body 6 is painted. This device has the advantages of being convenient for continuous painting on high walls and enhancing the wall painting construction efficiency.

[0034] Compared with the related art, the painting device for building wall decoration provided by the present invention has the following beneficial effects:

[0035] The present invention provides a painting device for building wall decoration. First, the limiting structure 4 and the positioning structure 5 are respectively and fixedly installed on the top edge of the building main body 6 and the side wall at the bottom end of the building main body 6 in a corresponding manner, so that the positions of the positioning structure 5 and the limiting structure 4 are symmetrical. Then, the lifting structure 3 is installed on the limiting structure 4, so that the lifting structure 3 hoists the painting structure 2. Then, two groups of the limiting structures 7 are installed between the limiting structure 4 and the positioning structure 5, so that the upper and lower ends of the two groups of the limiting structures 7 are connected together through the fixed pipe, and the limiting structure 7 slides on the back of the painting structure 2 through the first pulley 25. Furthermore, the limiting structure 7 has a certain squeezing effect on the painting structure 2, so that one end of the painting structure 2 abuts against the side wall of the building main body 6. Under the squeezing of the limiting structure 7, the abutting end of the painting structure 2 is in a compressed state, restricting the position of the brush retracting structure. Then, by connecting the lifting structure 3 to an external power source, the painting structure 2 can be driven to move up and down on the side wall of the building main body 6 by winding the steel cable 33. Under the guiding of the guiding pipe 1 by the feeding pump, the paint is conveyed to the inside of the corresponding painting roller 23 through the flow dividing structure 8. The paint is absorbed by the painting roller 23 and then smeared on the side wall of the building main body 6 under the extrusion of the side wall of the building main body 6. By connecting the first motor 31 and the second motor 42 in the limiting structure 4 and the positioning structure 5 to an external power source at the same time, the two motors operate synchronously, so as to drive the painting structure 2 to displace laterally and paint other positions on the side wall of the building main body 6. This device has the advantages of being convenient for continuous painting on high walls and enhancing the wall painting construction efficiency.
