Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, and more specifically, to a wind turbine tower body coating support device. Background Technology

[0002] The wind turbine tower is located beneath the wind turbine main unit and rotor, supporting these components which weigh tens of tons. A wind turbine tower is generally divided into several sections. The overall tower body is a hollow cylinder or frustum-shaped cone, and each section is also a hollow cylinder or frustum-shaped cone—a cylinder that is larger at one end and smaller at the other. Each section is composed of multiple rolled smaller cylinders joined together. Flanges are then welded to both ends of each section; these are inner flanges. High-strength bolts are used to connect the sections to form the entire tower. Because each wind turbine tower has a service life of approximately 20 years, the tower body requires high corrosion resistance.

[0003] When painting a tower, a support device is needed for support before the painting work can proceed. Existing tower support devices are equipped with several rollers to facilitate the rotation of the tower. However, because the surface of the tower is relatively smooth, the tower may slip off the support device during operation, thus affecting the efficiency of the painting process. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a wind turbine tower body coating support device, which has the advantage of more precise operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower body coating support device, comprising: a base, a bottom plate, and a support plate; the base is provided with several sliding grooves and mounting grooves, each sliding groove having a first lead screw rotatably connected inside, one end of the first lead screw extending outside the sliding groove, each first lead screw being connected to a movable frame, the end of the movable frame away from the movable frame being rotatably connected to a roller, the side of the roller being in contact with the tower body; a motor and a cylinder are respectively provided on the base, the motor and cylinder being respectively installed inside the mounting groove, each motor having a second lead screw connected to both sides, each second lead screw having a slider connected to a slider, the support plate being connected to one end of the slider, the end of the support plate away from the slider having a clamping block, the clamping block and one side of the support plate being in contact with the side of the tower body; the side of the cylinder away from the mounting groove is connected to the bottom plate, the side of the bottom plate away from the cylinder is in contact with the tower body, the support plate and the side of the bottom plate near the tower body are both machined with arc-shaped grooves.

[0006] As a preferred embodiment of this utility model, a rotating component is fixed at one end of the first lead screw extending to the outside of the slide groove, and both sides of the movable frame are in contact with the inner wall of the slide groove; this makes it convenient for people to rotate the first lead screw to move the movable frame.

[0007] As a preferred technical solution of this utility model, the bottom plate has a groove on the side near the cylinder, the second lead screw is set inside the groove, and the slider is slidably connected to the groove; this can save the space occupied by the drive structure on the base.

[0008] As a preferred embodiment of this utility model, the slider and the clamping plate are both connected to the support plate in an "L" shape; this facilitates extending the position of the clamping plate to fix cylinders of different lengths.

[0009] As a preferred embodiment of this utility model, a guide rod is connected to the side of the support plate near the clamping plate, and an elastic component is sleeved on the guide rod. The clamping plate is slidably connected to the guide rod, and both ends of the elastic component are connected to the support plate and the clamping plate respectively, making it convenient for people to pull the position of the clamping plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a base plate and several support plates on the base to support the cylinder, and setting a drive structure on the base plate and support plates respectively, the base plate can be driven to lift the cylinder, so that people can have a wide operating space when placing and removing the cylinder.

[0017] like Figures 1 to 4 As shown, this utility model provides a wind turbine tower body coating support device, including: a base 1, a base plate 6, and a support plate 13; the base 1 is provided with a plurality of sliding grooves 2 and mounting grooves 9, each sliding groove 2 is rotatably connected to a first lead screw 3, one end of the first lead screw 3 extends to the outside of the sliding groove 2, and each first lead screw 3 is connected to a movable frame 4, the end of the movable frame 4 away from the movable frame 4 is rotatably connected to a roller 5, the side of the roller 5 is in contact with the cylinder body 7; a motor 10 and a cylinder 11 are respectively provided on the base 1, and the motor 10 and the cylinder 11 are respectively mounted on the... Inside the mounting groove 9, the motor 10 is connected to two second lead screws 12 on both sides, and sliders 14 are connected to the second lead screws 12. The support plate 13 is connected to one end of the slider 14. A clamping block is provided at the end of the support plate 13 away from the slider 14. The clamping block and one side of the support plate 13 are in contact with the side of the cylinder 7. The side of the cylinder 11 away from the mounting groove 9 is connected to the bottom plate 6. The side of the bottom plate 6 away from the cylinder 11 is in contact with the cylinder 7. The support plate 13 and the side of the bottom plate 6 near the cylinder 7 are both machined with arc-shaped grooves 17.

[0018] The first lead screw 3 has a rotating component fixed at one end extending to the outside of the slide groove 2, and both sides of the movable frame 4 are in contact with the inner wall of the slide groove 2; this makes it convenient for people to rotate the first lead screw 3 to move the movable frame 4.

[0019] The base plate 6 has a groove on the side near the cylinder 7, the second lead screw 12 is set inside the groove, and the slider 14 is slidably connected to the groove; this can save the space occupied by the drive structure on the base 1.

[0020] The slider 14 and the clamping plate 8 are connected to the support plate 13 in an "L" shape, which facilitates the extension of the position of the clamping plate 8 to fix cylinders 7 of different lengths.

[0021] The support plate 13 is connected to a guide rod 15 on the side near the clamping plate 8. An elastic component 16 is sleeved on the guide rod 15.

[0022] The working principle and usage process of this utility model are as follows: First, the cylinder 7 is placed on the base plate 6, and the rotating part at the top of the first lead screw 3 is rotated, so that the first lead screw 3 drives the moving frame 4 to move inside the slide groove 2 until the distance between the rollers 5 is consistent with the radius of the cylinder 7. Then, the motor 10 on the base 1 is started, so that the motor 10 drives the second lead screw 12 to rotate. Through the principle of lead screw transmission, the slider 14 is driven to slide, so that the distance between the sliders 14 increases or decreases until the support plate 13 moves to the appropriate position. At this time, the cylinder 11 in the mounting groove 9 can be controlled to lower the height of the base plate 6 until the outer side of the cylinder 7 is in contact with the rollers 5 and the arc groove 17. During the painting work, the inner side of the clamp 8 is always in contact with the cylinder 7 to prevent the cylinder 7 from sliding on the base plate 6 and the support plate 13. When it is necessary to release the fixation, people only need to pull the clamp 8 on the guide rod 15 away from the cylinder 7, and the elastic component 16 will drive the clamp 8 to automatically reset when people release their hands.
