Description

Technical Field

[0001] The utility model relates to the technical field of tower barrel flanges, in particular to a dummy flange device for wind power tower barrel painting. Background Technique

[0002] In the processing of wind power tower barrels, in order to improve the corrosion resistance of the tower barrels, it is generally necessary to paint the surface of the tower barrels and spray anti-corrosion coatings on the surface of the tower barrels. Since the diameter of the tower barrels is relatively large and the length of a section of the tower barrel is relatively long, during the painting of wind power tower barrels, the wind power tower barrels are usually placed flat and a roller support structure is arranged at the bottom of the tower barrel. The tower barrel can rotate on the roller support mechanism, so as to spray the surface of the tower barrel comprehensively. However, since there is contact between the support structure and the side wall of the tower barrel, during the spraying process, in order not to damage the paint, after spraying a certain area on the surface of the tower barrel, it is necessary to wait for the paint to dry before rotating the tower barrel to spray the next area of the tower barrel. This requires additional time to wait for the paint to dry, and the spraying takes a long time. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dummy flange device for wind power tower barrel painting to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A dummy flange device for wind power tower barrel painting, including two support frames and two flange plates. The two flange plates are located between the two support frames. A plurality of threaded holes are annularly and equidistantly arranged on the side surface of the flange plate. The inner side surface of the top of the support frame is rotatably connected with a support cylinder. A connection groove is arranged on the side surface of the support cylinder. The inner side surface of the connection groove is rotatably connected with a rotating cylinder. Plugging rods are fixedly connected to the opposite surfaces of the two flange plates, and the side surface of the plugging rod is slidably connected with the inner side surface of the adjacent rotating cylinder.

[0006] Furthermore: Plugging rings are fixedly connected to the opposite surfaces of the two flange plates.

[0007] Preferably: A rectangular groove is arranged on the inner side surface of the connection groove. A rectangular block slidably connected with the inner side surface of the rectangular groove is fixedly connected to the side surface of the plugging rod. A lead screw is rotatably connected to the inner side surface of the support cylinder, and one end of the lead screw is screwed with the inner side surface of the adjacent rectangular block.

[0008] Furthermore, on the inner side of a support frame, there is a support plate fixedly connected. On the top surface of the support plate, there is a motor fixedly connected. The output end of the motor is drivingly connected to a transmission shaft. On the side of the support plate, there is a fixed frame fixedly connected to the side of the adjacent support frame. The side of the transmission shaft is rotatably connected to the inner side of the fixed frame, and the inner side of the fixed frame is rotatably connected to the side of the adjacent support cylinder. On the side of the transmission shaft inside the fixed frame, there is a gear fixedly sleeved. On the side of the support cylinder inside the fixed frame, there is a connecting frame fixedly connected. On the side of the connecting frame, there is a toothed ring fixedly connected, and the gear meshes and drives with the bottom of the toothed ring.

[0009] Preferably, two roller frames are rotatably connected to the bottom of the side of the support frame.

[0010] Furthermore, on one side of each of the two support frames away from each other, there are positioning plates provided. On the inner sides of both sides of the positioning plate, there are sliding rods rotatably connected. On the side of the sliding rod, there is a rotating rod slidably connected. On the top of the side of the rotating rod, there is a connecting shaft rotatably connected to the side of the support frame. On the inner side of the rotating rod, there is a spring fixedly connected to the inner side of the sliding rod.

[0011] Furthermore, two lifting frames are rotatably connected to the top of the side of the positioning plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By the side of the insertion rod being slidably connected to the inner side of the rotating cylinder, a screw can be screwed into the threaded hole and then into the threaded groove of the tower barrel, so as to connect the two flange plates to the end of the tower barrel through the screw and fix the tower barrel between the two support frames. The support frame can support the support cylinder, and the support cylinder can support the flange plate through the insertion rod, thereby supporting the tower barrel. There is no need to set a support structure at the bottom of the tower barrel. Neither the support frame nor the support cylinder will contact the side wall of the tower barrel. In this way, when the tower barrel rotates continuously between the two support frames and the surface of the tower barrel is fully sprayed, the support frame and the support cylinder will not damage the coating. After the surface of the tower barrel is fully sprayed, the paint on the surface of the tower barrel can be dried, and there is no need to spend multiple drying times, which is beneficial to accelerating the spraying treatment speed of the tower barrel.

[0014] 2. By one end of the screw rod being screwed and connected to the inner side of the adjacent rectangular block, the rectangular block can be restricted inside the rectangular groove through the screw rod, thereby restricting the insertion rod inside the support cylinder. When the support cylinder rotates, it can drive the insertion rod to rotate through the rectangular block, so that the flange plate and the tower barrel rotate, which is convenient for fully spraying the tower barrel. The screw rod can be rotated to move the rectangular block out of the rectangular groove. At this time, the flange plate can be removed from the support cylinder, so that the flange plate with a corresponding diameter can be replaced according to the size of the tower barrel, which is convenient for adapting to the support of tower barrels of different sizes.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , in the embodiments of the present utility model, the dummy flange device for wind power tower painting includes two support frames 1 and two flanges 2. The two flanges 2 are located between the two support frames 1. A number of threaded holes 21 are annularly and equidistantly formed on the side surface of the flange 2. The inner side surface of the top of the support frame 1 is rotatably connected with a support cylinder 3. A connection groove 32 is formed on the side surface of the support cylinder 3. The inner side surface of the connection groove 32 is rotatably connected with a rotating cylinder 33. Insertion rods 23 are fixedly connected to the opposite surfaces of the two flanges 2, and the side surface of the insertion rod 23 is slidably connected with the inner side surface of the adjacent rotating cylinder 33. Insertion rings 22 are fixedly connected to the opposite surfaces of the two flanges 2.

[0024] Specifically, after moving the tower barrel between the two flange plates 2, move the support frame 1 and the flange plate 2 to the end of the tower barrel, insert the insertion ring 22 into the tower barrel, and make the flange plate 2 abut against the end of the tower barrel. Then, screws can be screwed into the threaded holes 21 and further into the threaded grooves on the tower barrel, so that the two flange plates 2 are connected to the end of the tower barrel through the screws. The support frame 1 can support the support cylinder 3, and the support cylinder 3 can support the insertion rod 23 through the rotating cylinder 33, thereby supporting the flange plate 2, enabling the flange plate 2 to support the tower barrel. Neither the support frame 1 nor the support cylinder 3 contacts the side wall of the tower barrel, and there is no need to provide a support structure at the bottom of the tower barrel. The support cylinder 3 can rotate on the top of the support frame 1, so that the flange plate 2 and the tower barrel can continuously rotate between the two support frames 1. When spraying the entire surface of the tower barrel, the support frame 1 and the support cylinder 3 will not damage the coating. After the entire surface of the tower barrel is sprayed, the paint on the surface of the tower barrel is dried once, without the need to spend multiple drying times, which is conducive to accelerating the spraying process of the tower barrel.

[0025] Embodiment 1

[0026] As Figure 5 shown, in this embodiment, a rectangular groove 34 is formed on the inner side of the connection groove 32. A rectangular block 24 is fixedly connected to the side of the insertion rod 23 and is slidably connected to the inner side of the rectangular groove 34. A lead screw 31 is rotatably connected to the inner side of the support cylinder 3, and one end of the lead screw 31 is screwed into the inner side of the adjacent rectangular block 24.

[0027] During specific implementation, the lead screw 31 can restrict the rectangular block 24 inside the rectangular groove 34, thereby restricting the insertion rod 23 inside the support cylinder 3, and connecting the flange plate 2 to the support cylinder 3 more stably. The lead screw 31 can be rotated to move the rectangular block 24 out of the rectangular groove 34, causing the flange plate 2 to move away from the support cylinder 3. After the rectangular block 24 is disengaged from the lead screw 31, the flange plate 2 can be removed from the support cylinder 3. Then, the flange plate 2 with a corresponding diameter can be replaced according to the size of the tower barrel, so as to adapt to the support of tower barrels of different sizes. After connecting the new flange plate 2 inside the support cylinder 3 and inserting the insertion rod 23 into the rotating cylinder 33, since the insertion rod 23 and the rotating cylinder 33 can rotate relative to the support cylinder 3, the angle of the rectangular block 24 can be adjusted to enable the rectangular block 24 to be smoothly inserted into the rectangular groove 34.

[0028] As Figures 3 - 4As shown, in this embodiment, a support plate 6 is fixedly connected to the inner side of a support frame 1. A motor 63 is fixedly connected to the top surface of the support plate 6. The output end of the motor 63 is drivingly connected to a transmission shaft 61. A fixed frame 4 fixedly connected to the side surface of an adjacent support frame 1 is fixedly connected to the side surface of the support plate 6. The side surface of the transmission shaft 61 is rotatably connected to the inner side surface of the fixed frame 4, and the inner side surface of the fixed frame 4 is rotatably connected to the side surface of an adjacent support cylinder 3. A gear 62 is fixedly sleeved on the side surface of the transmission shaft 61 inside the fixed frame 4. A connecting frame 7 is fixedly connected to the side surface of the support cylinder 3 inside the fixed frame 4. A tooth ring 71 is fixedly connected to the side surface of the connecting frame 7, and the gear 62 meshes with the bottom of the tooth ring 71 for driving transmission.

[0029] During specific implementation, the support plate 6 can support the motor 63. After the tower barrel is connected between two flange plates 2 using screws and needs to be painted, the motor 63 can be driven to drive the transmission shaft 61 to rotate. The transmission shaft 61 can drive the tooth ring 71 to rotate through the gear 62. The tooth ring 71 can drive the connecting frame 7 to rotate, so that the support cylinder 3 rotates. The support cylinder 3 can drive the rectangular block 24 to rotate through the rectangular groove 34. The rectangular block 24 can drive the insertion rod 23 to rotate. The insertion rod 23 can drive the flange plate 2 to rotate. The flange plate 2 can drive the tower barrel to rotate through the screws, thereby comprehensively painting the side wall of the tower barrel.

[0030] Embodiment Two

[0031] Based on Embodiment One, as Figure 6 shown, in this embodiment, two roller frames 11 are rotatably connected to the bottom of the side surface of the support frame 1. Positioning plates 5 are arranged on both sides of the two support frames 1 away from each other. Sliding rods 53 are rotatably connected to the inner side surfaces on both sides of the positioning plate 5. A rotating rod 52 is slidably connected to the side surface of the sliding rod 53. The top of the side surface of the rotating rod 52 is rotatably connected to a connecting shaft 54 rotatably connected to the side surface of the support frame 1. A spring 55 fixedly connected to the inner side surface of the sliding rod 53 is fixedly connected to the inner side surface of the rotating rod 52. Two lifting frames 51 are rotatably connected to the top of the side surface of the positioning plate 5.

[0032] During specific implementation, the roller stand 11 facilitates the movement of the support stand 1, making it easy to move the support stand 1 to the end of the tower barrel, so that the flange 2 abuts against the end of the tower barrel. At this time, the positioning plate 5 can be moved downward. After the positioning plate 5 moves to the bottom of the connecting shaft 54, under the action of the spring 55, the sliding rod 53 can extend out of the rotating rod 52, enabling the positioning plate 5 to continue moving downward and abut against the ground, thereby positioning the support stand 1. When the painting is completed and it is necessary to move the support stand 1 away from the end of the tower barrel, the lifting frame 51 can be moved upward to disengage the positioning plate 5 from the ground. After the positioning plate 5 moves to the top of the connecting shaft 54, under the action of the spring 55, the sliding rod 53 can extend out of the rotating rod 52, so that the positioning plate 5 continues to move upward. At this time, the positioning plate 5 can be supported by the spring 55. After the positioning plate 5 is moved upward by a certain height, the lifting frame 51 can be rotated so that the lifting frame 51 extends into the bottom of the support stand 1, and the lifting frame 51 is supported by the bottom cross bar of the support stand 1, thereby maintaining the height of the positioning plate 5 and facilitating the release of the fixation of the position of the support stand 1.
