[0001] The utility model relates to the technical field of spraying, in particular to a coating structure for a wind power tower barrel. Background Art

[0002] With the wide application of wind power products, the using manufacturers have higher and higher requirements for the internal performance and appearance of wind power equipment, especially for the rust prevention treatment and surface spraying of wind power tower barrels. The tower barrel is the main supporting component of wind power products, and the using environment of the tower barrel is relatively harsh. If the spraying or rust prevention treatment of the tower barrel is not in place, it will seriously affect the service life of the tower barrel, thereby reducing the service life of wind power products as a whole and causing huge economic losses.

[0003] In the prior art, the Chinese patent document with the patent number CN210935552U proposes a spraying device for a wind power tower barrel, which includes a track, a trolley moving along the track, a spray gun and a rotating device. The rotating device includes a relatively arranged rotating motor and a rotating bracket. The rotating motor is connected to a first rotating shaft, and a expansion chuck for fixing one end of the tower barrel is arranged at the end of the first rotating shaft. The rotating bracket includes a bracket, a second rotating shaft and a expansion chuck for fixing the other end of the tower barrel; the spray gun is connected to the spray gun through an adjustable spray gun bracket. This spraying device has a simple structure, is easy to operate, and has a high spraying efficiency. The above spraying device can evenly spray the tower barrel, and there will be no phenomenon of incomplete spraying caused by the blockage of the clamping tool; moreover, the movement of the spray gun and the rotation of the tower barrel are both controlled by a control system, and there is no need for workers to be in close contact, which reduces the harm to workers. However, in the actual use process, the coverage of the clamping part will cause problems such as incomplete spraying, and in the actual use process of the above spraying device, the position of the tower barrel cannot be fixed. Therefore, the utility model proposes a coating structure for a wind power tower barrel to meet the requirement of improving the spraying effect when spraying the tower barrel. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to propose a coating structure for a wind power tower barrel to solve the problem of incomplete spraying caused by the coverage of the clamping part.

[0005] Based on the above purpose, the utility model provides a coating structure for a wind power tower barrel, which includes a support seat. A support plate is fixedly connected to the top of the support seat, and a connecting plate is fixedly connected to the support plate. It is characterized in that a fixing component is arranged on the inner wall of the support plate, and a spraying component is fixedly connected to the connecting plate;

[0006] The fixing component is used to fix the sprayed tower barrel; the fixing component includes a limiting plate rotatably connected to the inner wall of the top of the support plate. An annular sliding groove is formed on one side of the limiting plate, and a plurality of rotating seats are slidably connected in the annular sliding groove. The rotating seats are fixedly connected to the inner wall of the support plate. An expansion arm is rotatably connected to the rotating seat through a connecting rod. The expansion arm is a structure that expands outwards. A moving seat is rotatably connected to one side of the expansion arm. The moving seat is rotatably connected to a moving disk. The moving disk is coaxially arranged with the limiting plate. A first threaded rod is fixedly connected to one side of the moving disk. The first threaded rod penetrates through the limiting plate, and a first limiting disk is fixedly connected to the bottom of the first threaded rod.

[0007] The spraying component is used to spray the surface of the tower barrel.

[0008] Further improvement lies in that the spraying component includes a second threaded rod rotatably connected to the inner wall of the connecting plate. A guide rod is also fixedly connected to the inner wall of the connecting plate. The guide rod is located above the second threaded rod. A moving table is sleeved on both the second threaded rod and the guide rod. Second limiting disks are fixedly connected to both ends of the second threaded rod. A bearing table is arranged on one side of the moving table, and a spraying mechanism is arranged in the bearing table.

[0009] Further improvement lies in that the thread formed on the second threaded rod is in the shape of a bidirectional reciprocating thread.

[0010] Further improvement lies in that a plurality of connecting rods are fixedly connected to one end of the limiting plate. The connecting rods penetrate through the support plate. Grooves adapted to the connecting rods are formed on the support plate. A connecting disk is fixedly connected to one end of the connecting rods. A rotating handle is rotatably connected to one end of the connecting disk.

[0011] Further improvement lies in that a plurality of contact grooves are formed on one side of the top of the expansion arm. The surface of the contact grooves is made of rubber.

[0012] Further improvement lies in that a contact ball is fixedly connected to the top of the expansion arm. The contact ball is spherical. The contact ball is made of rubber. The contact ball preferably contacts the inner wall of the tower barrel first.

[0013] The beneficial effects of the present utility model:

[0014] 1. When painting a wind power tower barrel, by contacting the inner wall expansion arm of the tower barrel, turning the turning handle, synchronously driving the connection plate to rotate, and at the same time driving the connecting rod to rotate, thereby driving the limiting plate to rotate. When the limiting plate rotates, the first threaded rod drives the moving plate to rotate to one side, and then drives the expansion arm to synchronously rotate around the axis of the rotating seat, that is, the expansion arm realizes the expansion effect. Therefore, the contact groove and the contact ball on one side of the top of the expansion arm are in contact with the inner wall of the tower barrel. Since the surface of the contact groove is made of rubber structure and the contact ball is spherical, it avoids damaging the inner wall of the tower barrel during the process of supporting and fixing the tower barrel, and further improves the fixing effect during the spraying of the tower barrel.

[0015] 2. When painting a wind power tower barrel, by pushing the moving platform to move along the axis of the guiding rod, and at the same time spraying the tower barrel on the fixing component through the spraying mechanism in the bearing platform. Since the thread of the second threaded rod is of a double - direction reciprocating thread shape, it ensures that the moving platform can reciprocate on the second threaded rod, thereby ensuring the comprehensiveness during the spraying of the tower barrel, avoiding omission during the spraying process, and improving the spraying effect.

[0024] As Figures 1-4 shown, a coating structure for a wind power tower includes a support base 1. A support plate 2 is fixedly connected to the top of the support base 1. A connecting plate 3 is fixedly connected to the support plate 2. A fixing component is provided on the inner wall of the support plate 2. A spraying component is fixedly connected to the connecting plate 3. The fixing component is used to fix the sprayed tower, and the spraying component is used to spray the surface of the tower. When coating the wind power tower, the tower to be coated is fixed through the fixing component to ensure stable fixation during the coating process. Then, the spraying component evenly sprays the paint on the surface of the tower, enabling efficient coating of the wind power tower and ensuring uniform paint and reliable quality.

[0025] As Figures 2-4As shown in the figure, the fixing component includes a limiting plate 4 rotatably connected to the inner wall of the top of the support plate 2. An annular chute is formed on one side of the limiting plate 4. A plurality of rotating seats 5 are slidably connected in the annular chute. The rotating seats 5 are fixedly connected to the inner wall of the support plate 2. An expansion arm 6 is rotatably connected to the rotating seat 5 through a connecting rod. The expansion arm 6 is a structure that expands outwards. A moving seat 8 is rotatably connected to one side of the expansion arm 6. The moving seat 8 is rotatably connected to the moving disk 7. The moving disk 7 is coaxially arranged with the limiting plate 4. A first threaded rod 9 is fixedly connected to one side of the moving disk 7. The first threaded rod 9 threadedly penetrates through the limiting plate 4. A first limiting disk 10 is fixedly connected to the bottom of the first threaded rod 9. A plurality of connecting rods 11 are fixedly connected to one end of the limiting plate 4. A groove adapted to the connecting rods 11 is formed on the support plate 2. The plurality of connecting rods 11 penetrate through the support plate 2 through the same groove. One end of the connecting rod 11 is fixedly connected to a connecting disk 12. A rotating handle 13 is rotatably connected to one end of the connecting disk 12. A plurality of contact grooves 14 are formed on one side of the top of the expansion arm 6. The surface of the contact groove 14 is made of rubber. A contact ball 15 is fixedly connected to the top of the expansion arm 6. The contact ball 15 is spherical. The contact ball 15 preferably contacts the inner wall of the tower barrel. When painting the wind power tower barrel, by bringing the inner wall of the tower barrel into contact with the expansion arm 6, and by rotating the rotating handle 13, the connecting disk 12 is synchronously driven to rotate, and at the same time the connecting rod 11 is driven to rotate, thereby driving the limiting plate 4 to rotate. When the limiting plate 4 rotates, the first threaded rod 9 drives the moving disk 7 to rotate to one side, thereby driving the expansion arm 6 to synchronously rotate around the axis of the rotating seat 5, that is, the expansion arm 6 realizes the expansion effect. Therefore, the contact groove 14 on one side of the top of the expansion arm 6 and the contact ball 15 contact the inner wall of the tower barrel. Due to the surface of the contact groove 14 being made of rubber and the contact ball 15 being spherical, damage to the inner wall of the tower barrel during the process of supporting and fixing the tower barrel is avoided, and the fixing effect during the spraying of the tower barrel is further improved.

[0026] As Figure 1 , Figure 2 and Figure 4As shown in the figure, the spraying assembly includes a second threaded rod 16 rotatably connected to the inner wall of the connecting plate 3. The thread formed on the second threaded rod 16 is in the shape of a bidirectional reciprocating thread. A guide rod 17 is also fixedly connected to the inner wall of the connecting plate 3. The guide rod 17 is located above the second threaded rod 16. A moving platform 18 is sleeved on both the second threaded rod 16 and the guide rod 17. Second limiting discs 19 are fixedly connected to both ends of the second threaded rod 16. A bearing platform 20 is provided on one side of the moving platform 18. A spraying mechanism is arranged inside the bearing platform 20. When painting the wind power tower barrel, by pushing the moving platform 18 to move along the axis of the guide rod 17, and at the same time spraying the tower barrel on the fixing assembly through the spraying mechanism inside the bearing platform 20, the motor drives the second threaded rod 16 to rotate. Since the thread of the second threaded rod 16 is in the shape of a bidirectional reciprocating thread, it ensures that the moving platform 18 can reciprocate on the second threaded rod 16, thereby guaranteeing the comprehensiveness during the spraying of the tower barrel, avoiding omission during the spraying process, and improving the spraying effect.
