The first column 21 is a C-shaped column, that is, a shell with openings on three sides. The inner wall of the second column 22 is provided with a second slide groove 221. The height of the first column 21 and the second column 22 is less than the height of the door opening in the building. After the telescopic frame 3 is stored in the first column 21 and the second column 22, the device can be directly pushed into the building from the door opening, which is convenient for wall painting inside the building.

[0027] A supporting platform 211 is disposed on the top of the first column 21 , and a first motor 212 is disposed on the supporting platform 211 . A gear shaft 213 is fixedly connected to a fixed end of the first motor 212 , and the first motor 212 drives the gear shaft 213 to rotate.

[0028] A rack 31 is provided on the outer wall of the telescopic frame 3 near the first column 21, and the rack 31 is meshed with the gear shaft 213. When the gear shaft 213 rotates, the gear shaft 213 drives the rack 31 to rise and fall, and further makes the telescopic frame 3 rise or fall in height, completes the height adjustment, and finally aligns the height with the sitting height point to be painted. When the gear shaft 213 stops rotating, the gear shaft 213 prevents the rack 31 from moving, and further fixes the telescopic height of the telescopic frame 3. When the telescopic frame 3 needs to be stored, the gear shaft 213 is driven to reverse to make the telescopic frame 3 descend.

[0029] A slider 32 is provided on the outer wall of the telescopic frame 3 close to the second column 22. The slider 32 extends vertically and covers the outer wall of the telescopic frame 3. The slider 32 is slidably connected to the second slide groove 221. The second slide groove 221 limits the slider 32 to move only in the vertical direction.

The other end of the pull wire 8 is connected to the lifting block 4, and the pull wire 8 drives the lifting block 4 to rise and fall.

[0031] A tube collecting tube 13 is provided at the front end of the base 1, and a connecting tube 14 is provided in the tube collecting tube 13. The connecting tube 14 is coiled and stored in the tube collecting tube 13. One end of the connecting tube 14 is connected to the paint bucket 12, and the other end of the connecting tube 14 is connected to the lifting block 4. The connecting tube 14 transfers the paint in the paint bucket 12 to the lifting block 4. The paint bucket 12 has a built-in pump body, and the pump body provides power and pressure for the movement of the paint in the connecting tube 14. When the lifting block 4 rises, the lifting block 4 drives the connecting tube 14 in the tube collecting tube 13 to rise to ensure a continuous supply of paint. When the lifting block 4 descends, the connecting tube 14 is stored in the paint bucket 12.

[0032] The spraying mechanism 5 includes a paint spray head 51 and a brush wheel 52. The paint spray head 51 is rotatably connected to the front end of the lifting block 4. A paint channel is provided in the lifting block 4. The lifting block 4 is connected to the paint spray head 51 through a paint pipe. The paint is sprayed from the paint spray head 51 and adheres to the wall to be painted or the brush wheel 52. The brush wheel 52 is provided above the paint spray head 51. The brush wheel 52 can evenly apply the paint sprayed thereon to the wall.

[0033] like Figure 3As shown, a connecting shaft 41 is provided at the front end of the lifting block 4, and a connecting piece 511 is provided at the rear end of the paint spray head 51. The connecting piece 511 is rotatably connected to the connecting shaft 41, and a fastening nut 512 is detachably connected to the connecting shaft 41. When the fastening nut 512 is not tightened, the paint spray head 51 can be rotated arbitrarily relative to the front end of the lifting block 4 to adjust the inclination angle of the spraying. When the angle adjustment is determined, tighten the fastening nut 512 so that the fastening nut 512 presses the connecting piece 511 and the side wall of the lifting block 4 to limit the rotation of the paint spray head 51.

[0034] In actual operation, the track 11 is placed on the ground, the track 11 is perpendicular to the wall, the angle of the paint spray head 51 is adjusted so that the paint spray head 51 is aimed at the wall or the brush wheel 52, and then the pump body is started to make the paint spray head 51 spray paint on the wall, and the second motor 7 is started to drive the lifting block 4 to rise. When the lifting block 4 reaches the top of the telescopic frame 3, the first motor 212 is started to drive the telescopic frame 3 to rise to the roof, and the brush wheel 52 contacts the roof. Then the device is pushed to move back and forth along the track 11 to directly realize the painting of the roof, avoiding workers from climbing up to spray. After completing a spraying area, the whole can be moved to the next area; when only the side wall needs to be sprayed, the track 11 is placed horizontally, so that the device can be easily moved horizontally.
