Description

A wind-powered pin-type locking nut coated with anti-rust paint and its processing method Technical Field

[0001] This application relates to the field of wind turbine connection technology, and in particular to a wind turbine pin-type locking nut coated with anti-rust paint and its processing method. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It typically includes components such as a wind turbine, rotor, generator, and control system. When the wind turbine rotates due to the wind, the rotor drives the generator to produce electricity. Wind turbines can be installed in wind farms on land or offshore, utilizing natural wind energy to generate electricity. As a clean energy source, wind turbines are renewable and environmentally friendly, and are receiving increasing attention and application in more and more countries and regions.

[0003] The installation of a wind turbine typically involves the following steps: Determining the installation location: Selecting a suitable location for the wind turbine, usually in a relatively open area with abundant wind energy, such as high ground or near the coastline. Foundation construction: Wind turbines require a sturdy foundation to support their weight and withstand the effects of wind. Installing the wind turbine tower: Erecting and securing the wind turbine tower on the foundation. Installing the wind turbine blades and nacelle: Installing the wind turbine blades and nacelle onto the tower. Connections between wind turbine components are usually made using bolts and nuts to connect the components into a unified whole.

[0004] However, once the nut is exposed to the environment, it is prone to chemical reaction with the air, which can cause it to rust. Therefore, after the nut is processed, it needs to undergo surface treatment, such as galvanizing or painting. However, after the surface treatment, during the installation process, when the installation tools tighten the nut, they can damage the rust-proof surface of the nut, causing it to rust and affecting its strength. Summary of the Invention

[0019] 1. After the nut body is machined, a protective cover is fitted onto the nut to complete the machining. When connecting the nut to the bolt, the nut is screwed onto the bolt, and then the nut is rotated with the help of a tool. The nut moves on the bolt. When the bolt abuts against the indentation of the protective cover, the material within the indentation area separates from the protective cover to form a through hole for the bolt to pass through. In the above process, the tool acts directly on the protective cover, avoiding direct contact between the tool and the nut, thereby reducing the possibility of damage to the surface protective layer during the tightening process, reducing the possibility of nut corrosion, and thus extending the service life of the nut. At the same time, the protective cover separates the air from the nut, further reducing the possibility of nut corrosion. Attached Figure Description

Detailed Implementation

[0032] The present application will be further described in detail below with reference to Figures 1-8.

[0033] This application discloses a wind-powered pin-type locking nut coated with anti-rust paint. Referring to Figures 1 and 2, the wind-powered pin-type locking nut coated with anti-rust paint includes a surface-treated nut 1 and a protective cover 2 fitted over the outside of the nut 1. The protective cover 2 is made of elastic plastic. One end of the protective cover 2 has an opening for the nut 1 to enter, and the end of the protective cover 2 opposite to the opening has an indentation. The indentation is used to allow the bolt end to abut and fall, forming a through hole for the bolt to pass through. After the main body of the nut 1 is processed, the protective cover 2 is fitted onto the nut 1 to reduce the possibility of damage to the protective layer on the surface of the nut 1; at the same time, under the action of the protective cover 2, the thickness of the protective layer is appropriately reduced, thereby reducing the enterprise's input costs.

[0034] The implementation principle of a wind-powered pin-type locking nut coated with anti-rust paint in this application embodiment is as follows:

[0035] When nut 1 is connected to bolt, nut 1 is screwed onto bolt, and then nut 1 is rotated with the help of a tool. Nut 1 moves on bolt. When bolt abuts against the indentation of protective cover 2, the material within the indentation area separates from protective cover 2 to form a through hole for bolt to pass through. In the above process, the tool acts directly on protective cover 2, avoiding direct contact between the tool and nut 1, thereby reducing the possibility of damage to the surface protective layer during the screwing of nut 1, reducing the possibility of nut 1 corrosion, and thus extending the service life of nut 1.

[0036] This application discloses a processing method for a wind-powered pin-type locking nut coated with anti-rust paint. The method is used to form a wind-powered pin-type locking nut coated with anti-rust paint. Referring to Figures 3 and 4, a processing device is used. The processing device includes a worktable 3, on which a first vibrating plate 4 and a first conveying track 5 are provided. The surface-treated nut 1 is placed in the first vibrating plate 4. The first conveying track 5 is connected to the discharge end of the first vibrating plate 4. The vibrating plate is known technology for arranging and distributing materials, and will not be described in detail here. After the first vibrating plate 4 arranges the nut 1, it is placed flat on the first conveying track 5. The first conveying track 5 is inclined, and the height of the feed end of the first conveying track 5 is greater than the height of the processing end.

[0037] Referring to Figures 3 and 4, a second vibrating plate 6 and a second conveying track 7 are provided on the workbench 3. The second conveying track 7 is located directly above the first conveying track 5. The protective cover 2 is placed inside the second vibrating plate 6. The second conveying track 7 is connected to the processing end of the second vibrating plate 6. The second conveying track 7 is in an inclined state. The height of the feeding end of the second conveying track 7 is greater than the height of the processing end.

[0038] Referring to Figures 3 and 4, an assembly device 8 is provided on the workbench 3. The assembly device 8 is used to pick up the protective cover 2 on the second conveying track 7 and press it onto the nut 1.

[0039] Referring to Figures 3 and 4, an indentation device 9 is also provided on the worktable 3. The indentation device 9 is located on the side of the assembly device 8 away from the first conveying track 5. The indentation device 9 is used to indent the protective cover 2.

[0040] When assembling nut 1 and protective cover 2, nut 1 and protective cover 2 are placed in the first vibrating plate 4 and the second vibrating plate 6 respectively. Then, the first vibrating plate 4 and the second vibrating plate 6 are started. The first vibrating plate 4 places nut 1 in a flat position on the first conveying track 5 and slides along the first conveying track 5. The second vibrating plate 6 places protective cover 2 in a snap-fit ​​position on the second conveying track 7 and slides along the second conveying track 7. When nut 1 and protective cover 2 slide to the assembly device 8, the assembly device 8 presses protective cover 2 onto nut 1. Then, through-hole indentation is formed on protective cover 2 by indentation device 9. The operation is simple and convenient.

[0041] Referring to Figures 5 and 6, in this embodiment, a first through hole 10 is provided at the bottom of the second conveying track 7. The cross-section of the first through hole 10 is adapted to the cross-section of the nut 1. In this embodiment, the nut 1 is a hexagonal nut. The first through hole 10 allows the protective cover 2 to pass through the second conveying track 7 to the top of the first conveying track 5. The assembly device 8 includes a first electric push rod 81 disposed on the workbench 3 and a suction cup 82 disposed at the end of the conveying shaft of the first electric push rod 81. A first mounting frame 11 is disposed on the workbench 3. The first electric push rod 81 is disposed on the first mounting frame 11. The first electric push rod 81 is located above the second conveying track 7. The length direction of the conveying shaft of the first electric push rod 81 is perpendicular to the workbench 3 surface and faces the workbench 3 surface. The output shaft of the first electric push rod 81 is coaxial with the first through hole 10. The suction cup 82 is used to fix the protective cover 2 and is pressed onto the nut 1 by the first electric push rod 81.

[0042] After the protective cover 2 is conveyed to the first through hole 10 along the second conveying guide rail, the first electric push rod 81 is activated. The first electric push rod 81 drives the suction cup 82 to move toward the protective cover 2 and press it onto the protective cover 2. The suction cup 82 adsorbs and fixes the protective cover 2, and is placed above the nut 1 through the first through hole 10. Then the protective cover 2 is pressed onto the nut 1, completing the assembly of the protective cover 2 and the nut 1.

[0043] Referring to Figures 4, 5, and 6, to facilitate the separation of the suction cup 82 and the protective cover 2, an air pump 12 is provided on the first mounting bracket 11. An air pipe 13 is provided at the output end of the air pump 12. The air pipe 13 is a flexible tube and is connected to the suction cup 82. When the suction cup 82 and the protective cover 2 are separated, the air pump 12 is started. The air pump 12 introduces compressed air between the suction cup 82 and the protective cover 2 through the air pipe 13, thereby separating the suction cup 82 and the protective cover 2. The operation is simple and convenient.

[0044] Referring to Figures 5 and 6, to facilitate the suction cup 82 pressing onto the protective cover 2, a sliding plate 14 is slidably provided on the bottom surface of the second conveying track 7. The sliding plate 14 slides along the length direction parallel to the second conveying track 7. The bottom surface of the second conveying track 7 is provided with a first driving member for driving the sliding plate 14 to slide and opening and closing the first through hole 10. The first driving member includes a second electric push rod 15 provided on the bottom surface of the second conveying track 7. The length direction of the output shaft of the second electric push rod 15 is parallel to the length direction of the second conveying track 7. The sliding plate 14 is fixedly provided on the output shaft of the second electric push rod 15. After the sliding plate 14 closes the first through hole 10, a receiving groove for temporarily storing the protective cover 2 is formed between the first through hole 10 and the sliding plate 14, and the movement of adjacent protective covers 2 is blocked. When the protective cover 2 slides along the second conveying track 7, the protective cover 2 falls into the first through hole 10 and is supported by the sliding plate 14. Then, the first electric push rod 81 drives the suction cup 82 to adhere to the protective cover 2, and then the second electric push rod 15 drives the sliding plate 14 to slide and open the first through hole 10.

[0045] Referring to Figures 5 and 6, to facilitate the fitting of the protective cover 2 onto the nut 1, the first conveying track 5 is grooved, and the nut 1 moves within the groove 25. A connecting pipe 16 is provided on the first conveying track 5, located directly below the first through hole 10. The protective cover 2 passes through the first through hole 10 and the connecting pipe 16 to the nut 1. An electric heating wire 17 is arranged around the connecting pipe 16 and is electrically connected to the mains power. Furthermore, the bottom of the protective cover 2 is made of hard plastic. The electric heating wire 17 heats the protective cover 2, causing the inner diameter of the protective cover 2 to increase due to the heat, while the bottom of the protective cover 2 remains undeformed. When the protective cover 2 passes through the connecting pipe 16, the inner diameter of the protective cover 2 increases due to the heat, thus facilitating its fitting onto the nut 1. After the protective cover 2 cools down, its inner diameter decreases to secure it to the nut 1.

[0046] Referring to Figures 5, 6, and 7, to reduce the impact of adjacent nuts 1 on the first conveying track 5 on the nuts 1 to be fitted with the protective cover 2, a material distribution rod 18 is slidably provided at the bottom of the first conveying track 5. The material distribution rod 18 passes through the conveying track, and the sliding direction of the material distribution rod 18 is parallel to the axial direction of the nuts 1. The material distribution rod 18 is used to slide into the nut 1 behind the nut 1 to be processed, and a space exceeding the thickness of the protective cover 2 is reserved. A second driving component is provided on the worktable 3 to drive the material distribution rod 18 to slide. The second driving component includes... The third electric push rod 19 is placed on the workbench 3, and the material distribution rod 18 is coaxially arranged on the output shaft of the third electric push rod 19. When the nut 1 moves in the first conveying track 5, the nut 1 at the first end passes through the material distribution rod 18 and activates the third electric push rod 19. The third electric push rod 19 drives the material distribution rod 18 to slide and insert into the nut 1, thereby fixing the nut 1 on the material distribution rod 18. At the same time, it blocks the subsequent nuts 1 behind the material distribution rod 18, thereby reducing the impact of adjacent nuts 1 on the installation of the protective cover 2.

[0047] Referring to Figures 6, 7, and 8, in this embodiment, the indentation device 9 is located on one side of the end of the first conveying track 5 and on the extension line of the first conveying track 5. A third conveying track 20 is provided between the first conveying track 5 and the indentation device 9, and the third conveying track 20 is connected to the first conveying track 5. The installation station of the protective cover 2 is located on the first conveying track 5 and at its end. Furthermore, the installation station of the protective cover 2 is in a horizontal state. An air jet pipe 21 is provided on the workbench 3 and on the first conveying track 5. The air jet pipe 21 is located in front of the installation station of the protective cover 2. An air compressor 22 is provided on the workbench 3. 1 is connected to the output end of the air compressor 22. The third conveying track 20 is used to convey the nut 1 with the protective cover 2 to the indentation device 9. The third conveying track 20 is trough-shaped and multiple drive rollers 23 are rotatably arranged on both sides. The length direction and rotation axis of the multiple drive rollers 23 are perpendicular to the table surface of the worktable 3. The drive rollers 23 are evenly arranged on the third conveying track 20. After the nut 1 with the protective cover 2 enters the third track, the protective cover 2 abuts against the side wall of the drive roller 23. Furthermore, a motor is provided on the third track. One drive roller 23 located at the end is coaxially arranged on the output shaft of the motor. A conveyor belt 24 is arranged around all the drive rollers 23.

[0048] After the protective cover 2 is fitted with nut 1 at the work station, the air compressor 22 is started. The air compressor 22 compresses air and sprays it through the jet pipe 21. The sprayed air acts on the protective cover 2, moving the protective cover 2 to the third conveyor track 20. Then the motor is started, and the motor drives the drive roller 23 to rotate. The rotation of the drive roller 23 moves the protective cover 2 to the indentation device 9.

[0049] Referring to Figures 7 and 8, in this embodiment, the indentation device 9 includes a first pressing rod 91 and a second pressing rod 92 located on the worktable 3. The first pressing rod 91 and the second pressing rod 92 are respectively located on both sides of the third conveying track 20. Further, the second pressing rod 92 is slidably mounted on the third conveying track 20. The first pressing rod 91 and the second pressing rod 92 are coaxial and perpendicular to the worktable 3 surface. A nut 1 with a protective cover 2 is located between the first pressing rod 91 and the second pressing rod 92. Both the first pressing rod 91 and the second pressing rod 92 are slidably mounted on the worktable 3. The worktable 3 is provided with a mounting plate for the first pressing rod 91 and the second pressing rod 92. The third driving component, which presses against the protective cover 2, includes two fourth electric push rods 93. The first pressure rod 91 and the second pressure rod 92 are respectively mounted on the output shaft of the fourth electric push rod 93. When the protective cover 2 is conveyed to the position directly above the second pressure rod 92, the two fourth electric push rods 93 are activated. The first pressure rod 91 and the second pressure rod 92 move toward the protective cover 2. The second pressure rod 92 enters the nut 1 and abuts against the protective cover 2. The first pressure rod 91 acts on the protective cover 2. The first pressure rod 91 and the second pressure rod 92 apply pressure to the protective cover 2 to form an indentation on the protective cover 2. The operation is simple and convenient.

[0050] Referring to Figures 7 and 8, in order to facilitate indentation forming, grooves 25 are provided on the faces of the first pressure rod 91 and the second pressure rod 92 that are directly opposite each other. The grooves 25 are spherical and the maximum diameter of the grooves 25 is equal to the diameter of the first pressure rod 91 and the second pressure rod 92. Under the action of the grooves 25, the ends of the first pressure rod 91 and the second pressure rod 92 can easily enter the protective cover 2, thereby facilitating the formation of indentations on the protective cover 2.

[0051] Referring to Figures 7 and 8, a fixing plate 26 is further provided at the end of the third conveying track 20. The indentation station is located in front of the fixing plate 26. After the protective cover 2 abuts against the fixing plate 26, the indentation operation begins. Furthermore, notches 27 are provided on both sides of the third conveying track 20. After the indentation is completed, the protective cover 2 is moved out from the notches 27 to facilitate the indentation operation of the next protective cover 2.

[0052] The implementation principle of the processing method for a wind-powered pin-type locking nut coated with anti-rust paint in this application embodiment is as follows:

[0053] When assembling the nut 1 and the protective cover 2, place the nut 1 and the protective cover 2 in the first vibrating plate 4 and the second vibrating plate 6 respectively. Then start the first vibrating plate 4 and the second vibrating plate 6. The first vibrating plate 4 makes the nut 1 lie flat on the first conveying track 5 and slide along the first conveying track 5. The second vibrating plate 6 makes the protective cover 2 be in a snap-fit ​​state on the second conveying track 7 and slide along the second conveying track 7.

[0054] After the protective cover 2 slides to the first through hole 10, it falls into the first through hole 10. The first electric push rod 81 is activated to drive the suction cup 82 to adhere to the protective cover 2. Then, the second electric push rod 15 drives the slide plate 14 to slide and open the first through hole 10. When the nut 1 moves in the first conveying track 5, the nut 1 at the first end passes through the material distribution rod 18 and the third electric push rod 19 is activated. The third electric push rod 19 drives the material distribution rod 18 to slide and insert into the nut 1, thereby fixing the nut 1 on the material distribution rod 18.

[0055] The first electric push rod 81 drives the protective cover 2 to press onto the nut 1 via the connecting pipe 16. Then, the air compressor 22 is started. The air compressor 22 compresses air and sprays it through the jet pipe 21. The sprayed air acts on the protective cover 2, moving the protective cover 2 onto the third conveying track 20. Then, the motor is started, driving the drive roller 23 to rotate. The rotation of the drive roller 23 moves the protective cover 2 to the indentation device 9. When the protective cover 2 abuts against the fixing plate 26, the two fourth electric push rods 93 are started. The first pressure rod 91 and the second pressure rod 92 move toward the protective cover 2. The second pressure rod 92 enters into the nut 1 and abuts against the protective cover 2. The first pressure rod 91 acts on the protective cover 2. The first pressure rod 91 and the second pressure rod 92 apply pressure to the protective cover 2 to form an indentation on the protective cover 2. After the indentation is completed, the protective cover 2 is moved out of the third conveying track 20 through the notch 27 and falls onto the worktable 3.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
