Description

Technical Field

[0001] The invention relates to the technical field of spraying processing, in particular to rust-proof spraying equipment for a blade bracket of a wind turbine generator. Background Art

[0002] Wind turbine blades are large and fragile components. In order to transport them safely and efficiently, specially designed transport racks (such as Figure 8 ), the transport bracket can ensure that the wind turbine blades remain stable during transportation and reduce the risk of vibration and damage; since wind turbine blades are usually transported in outdoor environments and are exposed to wind and rain, the transport bracket needs to be sprayed with anti-rust paint to improve the weather resistance of the transport bracket and reduce damage to the transport bracket caused by environmental factors. In order to achieve uniform distribution of the coating and reduce the inconsistency of the coating thickness, the commonly used spraying method is electrostatic spraying.

[0003] When spraying a transport bracket, the bracket is usually placed on the support seat first, and then the surface of the bracket that is not in contact with the support seat is sprayed by rotating the bracket or moving the spray gun. The bracket is then rotated to separate the surface in contact with the support seat from the support seat, and then the unsprayed surface of the bracket is sprayed.

[0004] The current anti-corrosion spraying process has the following problems: there are usually multiple surfaces on the bracket that need to be sprayed, and each surface needs to be adjusted to the appropriate position before spraying, which requires the operator to constantly rotate the bracket or move the spray gun to treat each surface separately, thereby increasing the complexity of the entire spraying process and affecting the spraying processing efficiency; in addition, it is necessary to wait for the sprayed part to dry before clamping and rotating it to spray the unsprayed part, which easily leads to inconsistent spraying effect of the bracket.

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] As Figure 1 shown, an anti-rust spraying device for a wind turbine blade bracket includes an equipment rack 10, a bottom plate 11 is installed on the equipment rack 10, a support mechanism 3 for supporting the bracket is provided on the bottom plate 11, and a spraying mechanism 2 is also provided on the bottom plate 11.

[0034] As Figure 1 、 Figure 2 and Figure 4 shown, the spraying mechanism 2 includes a support 20, the support 20 is installed at the upper end of the bottom plate 11, the support 20 has an inverted L-shaped structure, a support plate 21 is installed at the front end of the horizontal section of the support 20, two liquid storage boxes 22 corresponding to each other up and down are slidably installed on the support plate 21, both liquid storage boxes 22 have a C-shaped structure, and the open ends of the two liquid storage boxes 22 are distributed facing each other. Atomizing nozzles 23 are uniformly communicated with the inner side walls of the liquid storage boxes 22, and liquid inlet pipes 24 are communicated with both liquid storage boxes 22.

[0035] As Figure 1 、 Figure 4 and Figure 8As shown, the support plate 21 is provided with a No. 1 guide portion 25 for guiding the upper liquid storage box 22 to move along the inner contour of the bracket, and the support plate 21 is also provided with a No. 2 guide portion 26 for guiding the lower liquid storage box 22 to move along the outer contour of the bracket, and the support 20 is provided with a driving portion 27 for driving the two liquid storage boxes 22 to move.

[0036] During specific operation, an external forklift places the bracket on the supporting mechanism 3, and then the driving part 27 drives the two liquid storage boxes 22 to move. The upper liquid storage box 22 moves along the inner contour of the bracket under the guidance of the No. 1 guide part 25, while the lower liquid storage box 22 moves along the outer contour of the bracket under the guidance of the No. 2 guide part 26. During the movement of the two liquid storage boxes 22, the external pump body is connected to the liquid inlet pipe 24 through the external delivery pipe to deliver the spray paint through the liquid inlet pipe 24 to the liquid storage box 22. The amount of spray paint in the liquid storage box 22 increases and the pressure increases, so that the spray paint is sprayed from the corresponding atomizing nozzle 23 and atomized and sprayed onto the bracket, thereby realizing the spraying processing of the bracket.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, the No. 1 guide portion 25 includes a guide groove 250, and the front end of the support plate 21 is provided with a guide groove 250 with the same contour shape as the inner side of the bracket, and the rear end of the upper liquid storage box 22 is installed with a roller 251 that slides with the guide groove 250, and the front end of the support plate 21 is rotatably installed with four No. 1 rollers distributed in a rectangular shape. The four No. 1 rollers are connected by a No. 1 chain plate 252, and a No. 1 support plate 253 is installed on the outer side of the No. 1 chain plate 252. A connecting component is provided between the upper liquid storage box 22 and the No. 1 support plate 253.

[0038] like Figure 2 As shown, the connecting assembly includes a support rod 254, and the support rod 254 is symmetrically installed on the No. 1 support plate 253 for sliding thereon. The right end of the support rod 254 passes through the No. 1 support plate 253 and is fixedly connected to the liquid storage box 22 above.

[0039] During specific operation, the driving part 27 drives the first chain plate 252 to rotate through the first roller shaft. The first chain plate 252 then drives the first supporting plate 253 to move downward. The first supporting plate 253 drives the liquid storage box 22 above to move downward through the support rod 254, so as to spray and process the vertical section inside the bracket. During the downward movement of the liquid storage box 22 above, through the guidance of the guiding groove 250, the liquid storage box 22 above moves horizontally to the left or right while moving downward, so as to maintain the effective distance between the atomizing nozzle 23 and the bracket, thereby ensuring the quality of the spraying process. As the first chain plate 252 rotates, the first supporting plate 253 moves from the right vertical section to the lower horizontal section. During its movement, the first supporting plate 253 drives the liquid storage box 22 above to rotate 90 degrees through the support rod 254, that is, the liquid storage box 22 with an initial opening to the right rotates to a state with an opening downward. Then the first chain plate 252 drives the liquid storage box 22 to move horizontally, so as to spray and process the horizontal section inside the bracket. Then the first supporting plate 253 moves from the lower horizontal section of the first chain plate 252 to the left vertical section, making the liquid storage box 22 rotate from an opening downward to an opening to the left, so as to spray and process the vertical section inside the bracket, thus realizing the spraying process of the inside of the bracket.

[0040] As Figure 1 , Figure 2 and Figure 4 shown, the second guiding part 26 includes a fixing frame 260. The rear end of the supporting plate 21 is provided with a fixing frame 260 through a pillar. The fixing frame 260 is in an X-shaped structure. Four ends of the fixing frame 260 are all rotatably installed with second roller shafts. The four second roller shafts are connected by a second chain plate 261 arranged thereon. The outer side wall of the second chain plate 261 is provided with a second supporting plate 262. The second supporting plate 262 is fixedly connected to the liquid storage box 22 below.

[0041] As Figure 4 shown, the driving part 27 includes a first motor 270. The rear end of the vertical section of the support 20 is provided with a first motor 270. The first motor 270 is connected to the corresponding second roller shaft through a bevel gear set 271. A first belt 272 is arranged between one of the first roller shafts and the corresponding second roller shaft for transmission connection.

[0042] During specific operation, the No. 1 motor 270 drives the corresponding No. 2 roller to rotate through the bevel gear set 271, and the No. 2 roller drives the corresponding No. 1 roller to rotate through the No. 1 belt 272, and the No. 1 roller drives the No. 1 chain plate 252 to rotate, so as to realize the drive of the upper liquid storage box 22, so that it can spray the inner side of the bracket. During the rotation of the No. 2 roller, the No. 2 chain plate 261 will also be driven to rotate, and the No. 2 chain plate 261 drives the No. 2 support plate 262 to move downward on its right vertical section, and the No. 2 support plate 262 drives the lower liquid storage box 22 to move downward, and the lower liquid storage box 22 sprays the vertical section of the outer side of the bracket through the atomizing nozzle 23. After the paint is applied, the No. 2 support plate 262 will rotate from the right vertical section of the No. 2 chain plate 261 to the lower horizontal section, thereby driving the liquid storage box 22 below, which is initially open to the left, to rotate to an open upward state, so that as the No. 2 chain plate 261 rotates, the corresponding liquid storage box 22 moves horizontally to spray the horizontal section on the outside of the bracket, and then the No. 2 support plate 262 moves from the lower horizontal section of the No. 2 chain plate 261 to the left vertical section, so that the corresponding liquid storage box 22 rotates from the opening upward to the opening to the right, and moves upward with the rotation of the No. 2 chain plate 261 to spray the left vertical section on the outside of the corresponding bracket.

[0043] like Figure 4 and Figure 5 As shown, the support mechanism 3 includes a fixing component, and two groups of fixing components are arranged on the left and right sides of the base plate 11. Each group of fixing components consists of two fixed blocks 30 opposite to each other in the front and rear directions. A limiting groove corresponding to the fixed block 30 is opened on the base plate 11, and the lower end of the fixed block 30 slides through the corresponding limiting groove. The opposite surfaces of the two fixed blocks 30 opposite to each other in the front and rear directions are both installed with limiting columns 31. The lower end of the base plate 11 is installed with an executive part 32 for driving the fixed block 30 to move, and the base plate 11 is provided with a supporting part 33 for supporting the bracket.

[0044] like Figure 5 and Figure 6 As shown, the executive part 32 includes a bidirectional screw 320, and two bidirectional screws 320 are symmetrically arranged at the lower end of the base plate 11. The bidirectional screw 320 is rotatably connected to the base plate 11 through a bearing seat, and the two threaded segments of the bidirectional screw 320 are respectively threadedly connected to the corresponding two fixed blocks 30. The two bidirectional screws 320 are connected by a No. 2 belt 321. A No. 2 motor 322 is installed on the base plate 11, and the No. 2 motor 322 is connected to one of the bidirectional screws 320 by a No. 3 belt 323.

[0045] During specific operation, an external forklift places the bracket on the supporting part 33. Then, the second motor 322 drives the corresponding bidirectional screw 320 to rotate through the third belt 323, and the two bidirectional screws 320 rotate synchronously through the second belt 321. The rotation of the bidirectional screw 320 drives the corresponding two fixing blocks 30 to move towards the bracket until the limit posts 31 are inserted into the corresponding mounting holes of the bracket to further restrict the movement of the bracket and improve its stability. When the liquid storage box 22 below needs to spray the horizontal section on the outside of the bracket, the second motor 322 drives the bidirectional screw 320 to rotate in the reverse direction, causing the fixing block 30 to drive the limit post 31 away from the bracket. Then, the liquid storage box 22 below can be guided by the second guiding part 26 to cross over the right fixing block 30 and the limit post 31. Then, the second motor 322 drives the bidirectional screw 320 to rotate forward again, causing the limit post 31 to be inserted into the mounting hole of the bracket again. Then, the supporting part 33 rotates away from the bracket to avoid interfering with the horizontal movement of the corresponding liquid storage box 22. After the liquid storage box 22 moves out of the rotation and supporting range of the supporting part 33, the supporting part 33 rotates back to support the bracket, and the second motor 322 drives the limit post 31 away from the bracket again, enabling the corresponding liquid storage box 22 to rotate to the left side of the bracket to spray the vertical section on the left side of the bracket.

[0046] As Figure 5 and Figure 6 shown, the supporting part 33 includes a shaft rod 330. Two shaft rods 330 are symmetrically arranged on the left and right on the bottom plate 11 and are located between two groups of fixing components. The lower end of the shaft rod 330 movably penetrates through the bottom plate 11. A supporting plate 331 for supporting the bracket is installed at the upper end of the shaft rod 330. A connecting plate 332 is rotatably installed at the lower ends of the shaft rods 330 together. A hydraulic cylinder 333 is installed at the lower end of the bottom plate 11. The telescopic end of the hydraulic cylinder 333 is fixedly connected to the connecting plate 332. A deflection component for guiding the deflection of the shaft rod 330 is arranged on the bottom plate 11.

[0047] As Figure 6 and Figure 7 shown, the deflection component includes a sleeve 334. The shaft rod 330 is movably sleeved with the sleeve 334. The upper end of the sleeve 334 is fixedly connected to the bottom plate 11. Guide grooves 335 are formed on both sleeve 334s. Guide posts 336 that are slidably matched with the corresponding guide grooves 335 are installed on the shaft rod 330.

[0048] As Figure 7 shown, the guide groove 335 is composed of an upper vertical section and a lower arc section. The vertical section lengths of the two guide grooves 335 are different, and the arc section directions of the two guide grooves 335 are opposite.

[0049] During specific operation, the hydraulic cylinder 333 pulls the two shaft rods 330 downward through the connecting plate 332. At this time, the guide posts 336 slide on the vertical sections of the corresponding guiding grooves 335, enabling the shaft rods 330 to drive the corresponding supporting plates 331 to move downward steadily away from the bottom surface of the bracket. As the shaft rods 330 move downward, the guide posts 336 move to the arc sections of the corresponding guiding grooves 335. Under the guidance of the arc sections of the guiding grooves 335, the supporting plates 331 rotate towards the middle of the bottom plate 11 until the supporting plates 331 are away from the bracket, so as to facilitate the movement of the liquid storage box 22 to spray the horizontal sections outside the bracket. Since the lengths of the vertical sections of the two guiding grooves 335 are different, the two supporting plates 331 will rotate in a staggered manner, thus avoiding interference between the two supporting plates 331.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0051] In addition, the terms "first", "second", "No. 1", "No. 2" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "No. 1", "No. 2" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0052] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0053] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
