[0001] This application relates to the field of wind power equipment painting technology, and in particular to a wind power cylinder painting fixing device. Background Technology

[0002] The cylindrical section of the wind turbine generator transition section is a large cylindrical structure. Due to its large size, the painting position needs to be constantly changed during the painting process to achieve painting of the entire outer circumference of the cylinder. Therefore, the existing technology makes the painting process of the cylinder complex. Furthermore, the requirement for the painting equipment to constantly change position significantly affects work efficiency. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this application is to provide a wind turbine cylinder painting fixing device, including a base. A pedestal is rotatably connected to the base, and a disc is rotatably connected to the pedestal. The disc is connected to a driving device, which drives the disc to rotate. The pedestal has at least two radially arranged slide rails, each slide rail slidably connected to a support rod. The device also includes connecting rods, the number of which corresponds to the number of support rods. One end of each connecting rod is hinged to the disc, and the other end is hinged to a support rod.

[0004] Preferably, the outer circumferential surface of the disk is provided with teeth, the driving device includes a telescopic rod, the telescopic end of the telescopic rod is provided with teeth that mesh with the teeth of the disk, and the fixed end of the telescopic rod is fixedly connected to the base.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following is in conjunction with the appendix Figure 1-2This application provides a further detailed description. An embodiment of this application discloses a wind turbine cylinder painting fixing device, including a base 1. A base 2 is rotatably connected to the base 1, and a disc 3 is rotatably connected to the base 2. The disc 3 is connected to a driving device 4, which drives the disc 3 to rotate. The base 2 has at least two slide rails 201 radially arranged, and each slide rail 201 is slidably connected to a support rod 5. The sliding connection between the slide rails 201 and the support rods 5 adopts conventional prior art. In this embodiment, the slide rail 201 is a U-shaped groove, and the support rod 5 is placed within the U-shaped groove. Connecting rods 6 are also included, with the number of connecting rods 6 corresponding to the number of support rods 5. At least two support rods 5 need to be in the same straight line and parallel to the diameter direction of the disc 3 to support the cylinder to be painted. To better support the cylinder, four support rods 5 are provided in this embodiment, corresponding to four slide rails 201 and four connecting rods 6. One end of the connecting rod 6 is hinged to the disc 3, and the other end of the connecting rod 6 is hinged to the support rod 5. The rotation of the disc 3 causes the multi-link structure formed by the connecting rod 6 and the support rod 5 to reciprocate linearly within the range of motion defined by the slide rail 201, driven by the rotation of the disc 3. This allows the end of the support rod 5 away from the disc 3 to achieve a telescoping effect relative to the outer edge of the base 2. At least two support rods 5 extend and support the inner annular surface of the cylinder to be painted, thus fixing the cylinder in place. The rotation of the base 2 relative to the base 1 is controlled manually or electrically, causing the cylinder to rotate with the base 2. This allows the painting equipment or operator to paint the entire outer surface of the cylinder without changing their own position, as the cylinder rotates with the base 2.

[0018] Furthermore, disk 3 can be coaxially connected to a motor to achieve rotation. Alternatively, it can be... Figure 1-2 As shown in the embodiment, the outer circumferential surface of the disk 3 is provided with teeth. The driving device 4 includes a telescopic rod, the telescopic end of which is provided with teeth that mesh with the teeth of the disk 3, and the fixed end of the telescopic rod is fixedly connected to the base 2. By extending and retracting the telescopic end of the telescopic rod, which serves as the driving device 4, the rotation direction of the disk 3 is controlled under the action of the meshing connection of the teeth. Furthermore, the extension and retraction of the telescopic rod control the forward and reverse rotation of the disk 3, respectively, thereby achieving the extension and retraction effect of the end of the support rod 5, which is hinged to the disk 3 through a multi-link structure, relative to the outer edge of the base 2. Specifically, the telescopic rod is hydraulically driven, that is, the telescopic rod is a hydraulic telescopic rod.

[0019] Furthermore, to control the telescopic movement direction of the telescopic rod's telescopic end, the base 2 is provided with a drive rail 202. The telescopic end of the telescopic rod is slidably connected to the drive rail 202, and the telescopic rod is located between the disc 3 and the drive rail 202. The drive rail 202 can be an elongated groove that accommodates the entire telescopic end of the telescopic rod. The two sides and the bottom edge of the groove, along with the teeth of the disc 3, surround the telescopic end of the telescopic rod, thus restricting its position and ensuring that it does not shift during telescopic movement. Alternatively, the telescopic end of the telescopic rod may have an elongated groove, and the drive rail 202 may be configured as a protrusion accommodated within this groove. It can also be any conventional prior art based on the sliding connection between the rail and the slider.

[0020] Furthermore, an elastic support block is provided at the end of the support rod 5 away from the disc 3 to buffer the pressure damage to the inner circumferential surface of the cylinder to be painted. It is noted that when two support rods 5 are installed, the support surface can be enlarged by setting the shape of the support block, for example, by setting an arc-shaped support block to fit against the inner circumferential surface of the cylinder to be painted.

[0021] Furthermore, the base 2 can be of any shape, and its size can be arbitrarily set according to actual conditions. When the base 2 is larger than the cross-section of the cylinder to be painted, the installation of the cylinder can be limited by the base 2 pressing against the cylinder. In this embodiment, the base 2 is disc-shaped, and the disc-shaped base is coaxially arranged with the disc. The diameter of the disc-shaped base 2 is smaller than the inner diameter of the cylinder to be painted, in order to prevent damage to the edge of the cylinder that may be caused when the base 2 presses against the cylinder.

[0022] Furthermore, the axial extension direction of the disc 3 can be arbitrarily set according to actual needs. For example, the axial extension direction of the disc 3 can be perpendicular to the ground, but this setting requires the painting equipment to have the ability to move up and down. In order to keep the equipment used in the painting process at the same height, so as to reduce the structural requirements of the painting equipment, the axis of the disc 3 is parallel to the ground, so that the painting equipment only needs to move horizontally along the ground to complete the painting.

[0023] Furthermore, the rotation of the base 2 can be driven manually or electrically. In this embodiment, the base 2 is provided with a rotating shaft, the base 1 is provided with a bearing, the rotating shaft is connected to the bearing, and the output shaft of the motor 7 is connected to the rotating shaft. The rotation of the base 2 is driven by the motor 7, thereby controlling the rotation of the fixed cylinder to be painted.

[0024] Working principle: The cylinder to be painted is hoisted and fitted onto the outside of the disc 3, with all support rods 5 located inside the cylinder. The disc 3 is rotated by the drive device 4. Driven by the connecting rod 6 hinged to the disc 3, the support rods 5, also hinged to the connecting rod 6, extend away from the disc 3 along the direction defined by the slide rail 201. The ends of the support rods 5 away from the disc 3 contact and support the inner circumferential surface of the cylinder to be painted. Then, the painting equipment is positioned to paint the outer circumferential surface of the cylinder. By rotating the base 2, the cylinder to be painted rotates accordingly, changing the position of the painting equipment relative to the outer circumferential surface of the cylinder, thus achieving painting of the entire outer circumferential surface of the cylinder.
