[0002] The wind power tower barrel is the tower pole of wind power generation, which mainly plays a supporting role in the wind power generating set and absorbs the vibration of the unit at the same time; the production process of the wind power tower barrel is generally as follows: cutting by a numerical control cutting machine, beveling is required for thick plates, after the plate is rolled into shape by a plate rolling machine, spot welding, positioning, and then welding of the inner and outer longitudinal seams after confirmation, after roundness inspection, if there is a problem, secondary rounding is carried out, after the single-section cylinder body welding is completed, hydraulic assembly roller frames are used for assembly and spot welding, and then the inner and outer circumferential seams are welded, after straightness and other tolerance inspections, the flange is welded, after weld non-destructive testing and flatness inspection, sandblasting and painting treatment are carried out, after the installation of internal parts and finished product inspection, it is transported to the installation site.

[0003] After the wind power tower is produced, paint needs to be sprayed on its outer wall to carry out a series of protections such as anti-oxidation. At present, before painting the cylinder body, it is necessary to carry out dust removal treatment on the place to be painted, and after painting, it is necessary to carry out drying treatment on the painted place. However, the existing painting devices do not have the above functions. Therefore, it is necessary to manually process the cylinder body before and after, which is very inconvenient and time-consuming. For this reason, we propose a painting assistance device for a wind power generation tower barrel, so as to realize the synchronous progress of the auxiliary work before and after painting.

An air outlet telescopic pipe communicating with the output end of the blower is connected to the top end of the air box, and an air inlet telescopic pipe communicating with the input end of the blower is connected to the bottom end of the air box.

[0008] By adopting the above technical solution, the effect of supplying air to the air suction plate and the drying plate is achieved.

[0009] The present utility model is further configured such that the air outlet telescopic pipe extends into the drying plate and is connected to the inside of the drying plate. An air outlet is provided on the inner end face of the drying plate, and an electric heating grid is installed inside the drying plate.

[0010] By adopting the above technical solution, the effect of drying the cylinder body after painting is achieved.

[0011] The present utility model is further configured such that the air inlet telescopic pipe extends into the dust suction plate and is connected to the inside of the dust suction plate. An air suction port is provided on the inner end face of the dust suction plate, and a filter screen is installed inside the dust suction plate.

[0012] By adopting the above technical solution, the effect of cleaning the cylinder body is achieved.

[0013] The present utility model is further configured such that side plates are slidably connected to the outer walls on both sides of the air box, and a connecting rod fixedly connected to the outer walls of both the drying plate and the dust suction plate is fixedly connected to the end of the side plate. The other end of the side plate is fixedly connected to an adjusting plate, and an adjusting bolt extending to the outer wall of the air box and connected to the outer wall of the air box through a bearing is installed inside the adjusting plate.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] 1. By setting the air suction plate and the drying plate, first, start the electric guide rail. The electric guide rail will drive the slider to move, and the slider will then drive the spray head to perform a painting operation on the cylinder body. At the same time, both the air suction plate and the drying plate will move synchronously with the paint box, and the blower inside the air box will also work. At this time, under the action of the blower, the air suction port at the end of the air suction plate will suck air from the outer wall of the cylinder body, and during this process, the dust and impurities on the unpainted parts of the cylinder body can be sucked out to achieve the cleaning effect of the cylinder body. The sucked air will enter the air suction plate and be filtered by the filter screen, and then the air will enter the drying plate through the air outlet pipe and be heated by the electric heating grid, and then be blown out through the air outlet to the position where the painting is completed to dry the painted part, improving the painting efficiency and quality;

[0017] 2. By providing an adjusting plate and adjusting bolts, when facing cylinders of different specifications, it is necessary to adjust the positions of the air suction plate and the drying plate to ensure the quality of dust removal and drying. Specifically, by rotating the adjusting bolts, the adjusting bolts will push the adjusting plate to move, and the movement of the adjusting plate will push the side plate to move. Thus, the side plate drives the air suction plate and the drying plate to move and adjust correspondingly through the connecting rod, thereby achieving the effect of adjusting the positions of the air suction plate and the drying plate and ensuring the auxiliary effect on the painting operation.
