Description

Rolling device for anti-corrosion spraying of wind turbine tower

technical field

The invention relates to an anti-corrosion spraying auxiliary tooling, in particular to a rolling device used for anti-corrosion spraying of a wind turbine tower.

Background technique

There are abundant wind resources on the earth. As a clean and non-polluting renewable energy, wind energy has attracted more and more attention. Therefore, wind power has become one of the renewable energy development projects that are generally concerned by countries all over the world.

The diameter of the bottom section of the tower of a megawatt-scale large-scale wind turbine is generally greater than 4 meters. When the painters spray the tower, the working area is very limited. Therefore, we need to rely on the rotation of the wind turbine tower to achieve the overall anti-corrosion spraying. Effect.

It can be seen from Figure 1 that in the prior art, the wind turbine tower 100 is directly placed on the roller frame 101, and the roller frame is in direct contact with the cylinder surface, but the contact surface between the roller frame and the wind turbine tower cylinder cannot be sprayed or other surfaces Drying and then spraying will affect the construction time and the overall effect of the anti-corrosion spraying of the cylinder. In order to facilitate the painter's work and improve production efficiency and quality, it is necessary to design a tooling for anti-corrosion spraying of wind turbine towers.

Contents of the invention

The technical problem to be solved by the present invention is to provide a rolling device for anti-corrosion spraying of a wind turbine tower, aiming at solving the above-mentioned problems.

In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

The present invention includes: a wind turbine tower; also includes: 2 roller frames; rolling wheels are placed on the roller frames; at least 2 brackets are fixed on the rolling wheels; the upper end of each bracket is connected to a detachable connection plate; the detachable connecting plate is fixedly connected to the flange surfaces at both ends of the wind turbine tower.

Compared with the prior art, the beneficial effect of the present invention is that the efficiency of the anti-corrosion spraying operation is improved, and the overall quality of the anti-corrosion is ensured at the same time, an uninterrupted overall anti-corrosion spraying operation of the cylinder body is realized, and the friction between the cylinder body and the roller frame is avoided. direct contact.

Fig. 4 is a view from Fig. 3A-A.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

It can be seen from Fig. 2, Fig. 3 and Fig. 4 that the present invention includes: a wind turbine tower 1; also includes: 2 roller frames 2; At least two brackets 4 are fixed; the upper end of each bracket 4 is connected to a detachable connecting plate 5 ; the detachable connecting plate 5 is fixedly connected to the flange surfaces at both ends of the wind turbine tower 1 .

The number of said at least two supports 4 is three, which are evenly distributed on the rolling wheel 3 .

The detachable connecting plate 5 is fixed at least in one place on the upper end of the bracket 4 .

The bracket on the rolling wheel is connected and fixed with bolts and the detachable connecting plate, and two rows of round holes are respectively opened on the bracket, and the length can be adjusted according to the size of the flange; then the detachable connecting plate is connected with bolts, gaskets and nuts Flange connection.

Technical advantage of the present invention:

The anti-corrosion spraying operation can be carried out at one time through the device, which avoids the problem of color difference at joints during the anti-corrosion spraying process.

Due to the adoption of the present invention, during the anti-corrosion spraying operation, the barrel spraying does not need to be completed step by step and does not need to wait for drying time, which greatly reduces time loss.

The form of rolling is adopted, which reduces the trouble of workers climbing and the danger of high-altitude operations, and realizes the anti-corrosion of the cylinder at one time, ensuring safety and improving production efficiency.

While simplifying the anti-corrosion operation process, by adjusting the angle of anti-corrosion spraying and other issues, the quality of anti-corrosion is greatly improved and the labor intensity is reduced. It avoids the direct contact between the cylinder body and the roller frame, and also avoids the operation blind area during the paint spraying process of the cylinder body.
