Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, and in particular to a painting equipment for the production of wind turbine towers. Background Technology

[0002] The wind turbine tower is the core supporting component of a wind turbine generator set. Its main function is to support the nacelle and blades at high altitudes to obtain more stable wind energy. It is mostly made of high-strength steel (a few are concrete or steel-concrete composite structures), and its shape is conical or cylindrical, with a larger diameter at the bottom and a smaller diameter at the top. The tower must possess extremely high structural strength, wind load resistance, and weather resistance. Since wind turbine towers are exposed to the outdoors for extended periods, they must withstand corrosion from ultraviolet rays, rain, salt spray, and sandstorms. Therefore, they require painting. The core functions of painting are corrosion and rust prevention, weather protection, and visual identification.

[0003] An existing painting device for wind turbine tower production (announcement number: CN220919610U) has many limitations and cannot meet the comprehensive needs of wind turbine tower production: This device primarily uses a U-shaped mounting frame and multiple first telescopic push rods to move the paint storage tank up and down, in conjunction with an adjusting motor to drive the mounting plate to rotate, and multiple second telescopic push rods to adjust the horizontal position of the paint nozzles, thus achieving the painting of the inner wall of the wind turbine tower. Its structural design results in a single function, only capable of treating the inner wall of the tower, unable to handle outer wall painting, requiring additional outer wall painting equipment, increasing production investment and operational complexity.

[0004] Meanwhile, the device employs multiple paint nozzles working in tandem, each requiring an independent paint outlet pipe, control valve, pump body, and paint guide hose. It also relies on multiple telescopic push rods (first, second, and third telescopic push rods) and adjusting motors for multi-dimensional adjustments, resulting in a highly complex structure. This not only increases manufacturing costs but also makes it difficult to detect malfunctions in individual nozzles, leading to uneven paint application, affecting paint quality, and impacting the overall painting process. Maintenance requires checking multiple components one by one, reducing production efficiency.

[0005] Given the problems of limited functionality and complex structure in existing technologies, it is necessary to propose a new type of painting device for wind turbine tower production to solve the above-mentioned drawbacks. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a painting device for wind turbine tower production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A painting device for wind turbine tower production includes an automatic spray gun, with a tower body disposed on one side of the automatic spray gun. It also includes a painting device for painting the tower body, disposed on one side of the tower body. The painting device includes a railcar, which is disposed on one side of the tower body. A support frame is movably fitted inside the railcar. A first circular through hole is formed on the top surface of the support frame. A support column is movably fitted onto the inner circular wall of the first circular through hole. A connecting frame is fixedly installed on the top surface of the support column. A transverse support tube is fixedly installed inside the connecting frame. A rectangular through hole is formed on the outer circular wall of the transverse support tube. A movable plate is movably fitted onto the inner circular wall of the transverse support tube. One side of the movable plate is fixedly installed to the automatic spray gun. A moving mechanism for moving the automatic spray gun is provided on one side of the movable plate.

[0008] As a further embodiment of this utility model, the moving mechanism includes: a threaded hole, the threaded hole being formed on one side of the moving plate, a threaded rod being threadedly connected to the inner circular wall of the threaded hole, and a baffle being fixedly installed on the inner circular wall of the transverse support tube, the baffle being movably sleeved with the threaded rod.

[0009] As a further embodiment of this utility model, a rectangular groove is provided on the outer circular wall of the movable plate, and a plurality of rotating wheels are installed inside the rectangular groove.

[0010] As a further embodiment of this utility model, a counterweight is fixedly installed at one end of the transverse support tube, a drive motor is fixedly installed on one side of the inside of the counterweight, and first circular through holes are opened on both sides of the counterweight. The threaded rod extends out from the inside of the first circular through hole and is fixedly installed at one end of the drive shaft of the drive motor.

[0011] As a further embodiment of this utility model, two tie rods and a tie bar are fixedly installed on both sides of the connecting frame, and the tie rods are fixedly installed with the transverse support tube.

[0012] As a further embodiment of this utility model, a first hydraulic cylinder is fixedly installed on the bottom surface of the support frame, and the first hydraulic cylinder is fixedly installed on the inner bottom surface of the railcar.

[0013] As a further embodiment of this utility model, a second hydraulic cylinder is hinged to one side of the support frame, and the second hydraulic cylinder is hinged to the transverse support tube.

[0014] As a further embodiment of this utility model, the bottom surface of the tower body is provided with several electrically controlled roller frames, which support the tower body. The bottom surface of the railcar is provided with two guide rails for supporting the rollers. A control console is provided on one side of the guide rails, and the control console is electrically connected to the automatic spray gun and the drive motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By using the automatic spray gun, tower body, railcar, support frame, and support column in coordination, the tower body can be painted. The reciprocating movement of the automatic spray gun, combined with the low-speed rotation of the tower body, achieves the outer wall painting. At the same time, the tower body is positioned in the forward direction of the horizontal support pipe, allowing the horizontal support pipe to enter the interior of the tower body, thereby achieving the inner wall painting. Furthermore, the single spray head reduces the failure rate; painting stops immediately upon blockage, preventing uneven painting. Maintenance also eliminates the need to troubleshoot multiple components, making it quite practical.

[0016] 2. The railcar can move laterally, which facilitates painting of other parts of the tower body. Furthermore, the support frame can be moved up and down by extending and retracting the first hydraulic cylinder, thereby adjusting the height of the connecting frame and the transverse support pipe. By activating the second hydraulic cylinder, the transverse support pipe is pulled to rotate horizontally, so that the transverse support pipe rotates and tilts to adapt to the shape of the tower body.
