Description

Technical Field

[0001] The utility model relates to the field of wind turbine main shafts, in particular to a spraying bracket for placing the wind turbine main shaft. Background Art

[0002] The wind turbine main shaft is a component used to transmit torque in a wind turbine. The front end of the wind turbine main shaft is provided with a hub connection flange, which is used to connect to the hub. The hub is the base for fixing blades, and the blades are installed on the hub to form a wind wheel. The tail end of the wind turbine main shaft is connected to the gear box. The axis of the wind turbine main shaft is provided with a through hole, which is the passage for the control cable, oil circuit or mechanical rod of the variable pitch mechanism. Since the side wall of the wind turbine main shaft needs to cooperate with the bearing in the wind turbine, the side wall of the wind turbine main shaft is prone to rust and wear. Once the side wall of the wind turbine main shaft is rusted and worn, it is necessary to stop the machine to repair the rust and wear. The position affects the normal operation of the wind turbine main shaft, so the wind turbine main shaft is usually sent to the spraying workshop after being manufactured and formed, and an anti-rust layer is sprayed on the designated position according to customer needs. In the prior art, the wind turbine main shaft is usually placed on an ordinary fixed bracket and then sprayed manually. However, the ordinary fixed bracket needs to be sprayed around the wind turbine main shaft manually, otherwise it cannot be sprayed evenly to the circumferential position of the wind turbine main shaft that needs rust prevention, or the main shaft is rotated manually, which will consume a lot of manpower, and because the bracket cannot be moved, the bracket needs to be moved into the workshop for spraying. Utility Model Content

[0003] The utility model aims to solve the above technical problems and to provide a spraying bracket which can be adjusted according to wind turbine main shafts of different sizes and can rotate automatically when spraying the wind turbine main shafts.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1

[0020] like Figure 1-3 As shown, a spraying bracket for placing a wind turbine main shaft comprises a main body 1, which is a rectangular bottom plate. A group of walking wheel groups are welded on both sides of the main body 1, and each group of walking wheel groups is provided with two parallel walking wheels 2. In this embodiment, the walking wheel is a universal wheel to adapt to the complex track and road conditions of the factory. The walking wheel group is uniformly controlled by a first driving motor to save manpower. The walking wheel group is slidingly arranged on a rail 3 leading to a spraying workshop. Two support members 4 for supporting the wind turbine main shaft are relatively arranged on the upper surface of the main body 1. Two wheel discs 5 with rotating shafts parallel to the ground are arranged on the support member 4. The wheel disc 5 is uniformly controlled to rotate by a rotating motor 6. The purpose of setting the wheel disc is that a wind turbine main shaft of any shape and size can be set up on it, and the self-axis rotation of the wind turbine main shaft can be limited by the relative rotation of the wheel disc, so that the staff only needs to stand in one position to complete the spraying of the required spraying area. In addition, the rotation is controlled by a rotating motor, which is convenient for the staff to control the rotation angle.

[0021] In order to be able to adjust the distance between the two supports to adapt to wind turbine main shafts of different lengths, specifically, in this embodiment, two parallel and mutually parallel slide rails 7 are provided in the middle of the main body 1 along the arrangement direction of the supports 4, and a slider 8 adapted to the slide rail 7 is provided at the bottom of the support 4. The slider 8 is controlled by the second drive motor. As is known to all, the wind turbine main shaft has different lengths according to the size of the wind turbine, so the slider rail can automatically adjust the distance between the two supports 4 to adapt to wind turbine main shafts of different lengths. In order to make the support 4 more stable when supporting, a further preferred technical solution is that both sides of the support 4 are provided with fixing members 9, and mounting holes are provided on the fixing members 9, and both sides of the slide rail 7 are provided with mounting plates 10, and the mounting plates 10 are evenly provided with a plurality of fixing holes 11 adapted to the mounting holes. Since the support member is slidable, when the support member stops and the spraying operation is carried out, there is a risk of the support member sliding during the operation. Therefore, a fixing member is provided and the fixing member is installed in the fixing hole by bolts to prevent the support member from moving during the spraying process. In addition, since wind turbine main shafts of the same length are usually sprayed in a batch, the bolt fixing does not mean that it needs to be frequently pulled out for position adjustment. In order to improve the stability of the fixing member, a further preferred technical solution is that the fixing member 9 is in the shape of a right triangle.

[0022] In order to adapt to wind turbine main shafts of different shaft diameters and more convenient spraying requirements at different positions, a further preferred technical solution is that the support member 4 is divided into a lifting part 12 and a fixed part 13 through a mounting groove 14 opened in the middle, and at least one cylinder push rod 15 is provided in the mounting groove 14. In this embodiment, one cylinder push rod is provided. If a heavy wind turbine main shaft is encountered, two or more cylinder push rods are usually required. The output end of the cylinder push rod 15 is connected to the bottom of the lifting part 12, and a rotating motor 6 is provided next to the cylinder push rod 15. Since the shaft diameter of each batch of wind turbine main shafts is different, the height of the support points at both ends of the wind turbine main shaft may be different. Therefore, a cylinder push rod is provided to adjust the height of the support point of the support member to adapt to different types of wind turbine main shafts, so as to be able to collect waste left over from spraying.

[0023] A further preferred technical solution is that the bottom of the main body 1 is detachably provided with a waste trough 16. During the spraying process, the waste of spraying will usually drip into the spraying workshop, which is not conducive to environmental protection. Therefore, a waste trough is set to collect the waste, which can be centrally processed after the spraying is completed. After the wind turbine main shaft is sprayed, it usually needs to be placed on a bracket to dry for two or three days to ensure that the anti-rust film is completely air-dried before leaving the factory. This results in one bracket being occupied and the entire production cycle being extended by two or three days. When there are many work orders, this undoubtedly affects the efficiency. Therefore, a further preferred technical solution is that a plurality of heating tubes 18 are provided on the waste trough 16. In this embodiment, 3 are provided. A drying fan 17 is provided on one side of the upper surface of the main body 1. After the spraying is completed, or during the spraying, the heating lamp and the drying fan are turned on at the same time for air drying, and the original wind turbine main shaft is kept rotating after the spraying is completed to dry it quickly. After inspection, the air drying that could be completed in two or three days can be compressed to 12 hours, thereby improving work efficiency.

[0024] The utility model provides a walking wheel set and rails, so that the wind turbine main shaft can be directly placed on the bracket after production is completed, and transported to the spraying workshop by the walking wheels, avoiding the previous need to transport the wind turbine main shaft to the bracket in the spraying workshop. The walking bracket can improve the transportation efficiency, thereby improving the work efficiency; in addition, a turntable is provided on the support member, and the main shaft is set between the two turntables. When the two turntables rotate relative to each other, the rotation of the main shaft can be automatically controlled, thereby facilitating the spraying of the main shaft and facilitating the workers to carry out the spraying work, thereby improving the workers' work efficiency.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
