Description

Technical Field

[0001] The invention relates to the technical field of stator varnish dipping, and in particular to an auxiliary device for stator varnish dipping of an exciter. Background Art

[0002] The exciter is an important component of the generator. Its stator needs to be varnished to improve the moisture resistance, electrical insulation strength, heat resistance and heat dissipation of the winding. It can also improve the mechanical properties and chemical stability of the winding insulation, thereby ensuring the normal operation of the exciter and extending its service life. In the production and manufacturing process of the exciter stator, the varnishing process is a key link to ensure the performance and quality of the stator.

[0003] During the traditional exciter stator varnishing operation, the stator is often fixed in a single position, and it is difficult to flexibly adjust the angle. As a result, during the varnishing process, some parts of the stator may not be fully exposed to the paint liquid, resulting in uneven varnishing, which seriously affects the insulation performance and service life of the stator. In addition, the process of lifting the exciter stator to the varnishing tank mainly relies on simple lifting equipment, and the operation process lacks precise control. During lifting, the stator is prone to displacement or even collision due to shaking, which may not only cause damage to the stator winding and affect the insulation performance, but also cause potential damage to the overall structure and increase the risk of equipment failure.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figures 1-11The present invention provides a technical solution: an auxiliary device for varnishing the stator of an exciter, comprising two fixed bases 1 and a control base 19. An adjusting groove 1901 is provided on the bottom outer wall of the control base 19. A second motor 1902 is fixedly provided on the outer wall of one side of the control base 19. A bidirectional screw rod 1904 is fixedly provided on the output end of the second motor 1902. The bidirectional screw rod 1904 is located inside the adjusting groove 1901. One end of the bidirectional screw rod 1904 away from the second motor 1902 is rotatably connected to the inner wall of the adjusting groove 1901. Two adjusting blocks 1903 are threaded on the outer wall of the bidirectional screw rod 1904. A fixing collar 1905 is fixed on the bottom outer wall of each adjusting block 1903. The inner wall of the fixed sleeve 1905 is rotatably provided with a connecting cylinder 1906, and the outer walls of the two connecting cylinders 1906 on the opposite side are fixedly provided with a limiting sleeve 1907, and the outer wall of one of the connecting cylinders 1906 is fixedly provided with a connecting ring 1908, and the outer wall of the connecting ring 1908 is evenly provided with a clamping groove 1909. The outer wall of the adjustment block 1903 located on the side of the second motor 1902 is provided with a seat groove 1910, and an elastic spring 1911 is fixedly provided on the top of the inner wall of the seat groove 1910. The outer wall of the other end of the elastic spring 1911 is fixedly provided with a clamping block 1913, and the outer wall of the clamping block 1913 on the side away from the adjustment block 1903 is fixedly provided with a shifting block 1912, and the shifting block 1912 is engaged with the corresponding clamping groove 1909;

[0035] In this embodiment, the exciter stator to be dipped in paint is placed stably between the two limiting collars 1907. After it is properly placed, the second motor 1902 is started to drive the bidirectional screw 1904 to rotate. Under the action of the bidirectional screw 1904, the two adjustment blocks 1903 threadedly connected thereto begin to approach each other along the screw. As the two adjustment blocks 1903 approach, the two limiting collars 1907 respectively connected thereto gradually approach and are tightly stuck on the inner wall of the stator, thereby achieving a firm clamping of the stator. When the stator is firmly clamped, the first motor 7 is started to drive the transmission gear 8 inside the installation box 5 to rotate, and the transmission gear 8 then drives the driven gear 802 to rotate, thereby controlling the retraction and extension of the steel rope 11, thereby achieving The control seat 19 drives the stator down to the paint dipping position and starts the paint dipping operation. During the paint dipping process, when the angle of the stator needs to be adjusted, the shift block 1912 is pushed upward to drive the card block 1913 to disengage from the slot 1909 on the outer wall of the connecting ring 1908, and the connecting ring 1908 is no longer restricted by the card block 1913. Rotating the connecting ring 1908 can drive the limiting ring 1907 and the stator stuck by it to rotate together, thereby adjusting the angle of the stator to ensure that all parts of the stator can be evenly dipped in paint. After adjusting to the appropriate angle, release the shift block 1912, and the card block 1913 is reset under the elastic action of the elastic spring 1911 and re-locked into the corresponding slot 1909 to ensure the stability of the stator during the paint dipping process.

[0036] The top outer walls of the two fixed bases 1 are fixedly connected to support beams 2, and two cross beams 3 are fixedly connected between the upper ends of the two support beams 2, with a gap between the two cross beams 3. Movable grooves 4 are provided on the outer walls on the opposite sides of the two cross beams 3, and an installation box 5 is movably connected between the two cross beams 3. The outer walls of both sides of the installation box 5 are fixedly connected to support sliders 501, and the outer walls of the two support sliders 501 are movably connected to the inner walls of the corresponding two movable grooves 4 respectively;

[0037] A working compartment 502 is provided at the bottom of the installation box 5, and a first motor 7 is fixedly installed on the outer wall of one side of the installation box 5. Two box holes 602 are provided on the outer walls of both sides of the installation box 5. A rotating shaft 801 is rotatably provided on the inner walls of the two box holes 602. A transmission gear 8 and a driven gear 802 are respectively installed between the two pairs of rotating shafts 801. One end of the rotating shaft 801 located at the transmission gear 8 is connected to the output end of the first motor 7, and a first mounting plate 9 is provided on the outer wall of the rotating shaft 801 at the end of the transmission gear 8 and the driven gear 802 away from the first motor 7. The first mounting plate 9 is fixedly connected to the installation box 5, and one end of the two rotating shafts 801 passing through the inner wall of the first mounting plate 9 is fixedly connected A rope drum 10 is connected, and a second mounting plate 12 is provided on the outer wall of the other end of the two rope drums 10. The outer walls of the two second mounting plates 12 on the side away from the mounting box 5 are fixedly connected to the same fixing plate 13. An electric push rod 14 is fixedly installed on the top of the fixing plate 13. A push plate 15 is fixedly installed on the output end of the electric push rod 14. A support plate 16 is fixedly connected to the outer wall of one side of the push plate 15. A plate groove 17 is opened on the top outer wall of the support plate 16. Steel ropes 11 are provided on the outer walls of the two rope drums 10. One end of the two steel ropes 11 is fixedly connected to the same hanging platform 18. The hanging platform 18 is located inside the plate groove 17, and the bottom outer wall of the hanging platform 18 is fixedly connected to the top of the control seat 19.

[0038] In this embodiment, the installation box 5 is slidably connected to the movable slot 4 of the crossbeam 3 via a support slider 501, ensuring stable movement of the installation box 5 within the gap between the crossbeams 3 and providing a basis for adjusting the horizontal position of the control base 19. The first motor 7, serving as the power source, drives the transmission gear 8 to rotate, driving the synchronous rotation of the driven gear 802. This enables the two pairs of rotating shafts 801 and the rope drum 10 to operate in coordination, achieving the retraction and extension of the steel rope 11. This gear transmission structure ensures the consistent rotation speed of the two rope drums 10, preventing uneven force on the steel rope 11 and causing the hanging platform 18 to tilt. The working chamber 502 provides an enclosed space for the transmission gear 8, the driven gear 802, and other components, reducing interference from external dust on the transmission. The first and second mounting plates 9 and 12 provide fixed support for the rotating shaft 801 and rope drum 10, ensuring their coaxiality during rotation. The electric push rod 14 on the fixed plate 13 pushes the support plate 16 via the push plate 15, supporting the hanging platform 18 from below when the stator is hoisted, preventing the stator from shaking due to a shift in its center of gravity and further improving the hoisting stability.

[0039] The bottom of the inner wall of the two movable grooves 4 is fixedly connected with a plurality of compression springs 20, the top outer wall of the two plurality of compression springs 20 is fixedly connected with a movable plate 401, and an elastic sealing frame 21 is provided between the two movable plates 401 and the inner wall of the movable groove 4;

[0040] In this embodiment, the compression spring 20 on the inner wall of the movable groove 4 and the movable plate 401 form a buffer mechanism. When the installation box 5 slides on the crossbeam 3 or vibrates due to stator hoisting, the movable plate 401 compresses the compression spring 20. The elastic deformation of the spring absorbs the impact force, preventing the installation box 5 from directly colliding with the bottom of the movable groove 4, thereby reducing the shaking during the stator hoisting process. The elastic sealing frame 21 is embedded between the movable plate 401 and the inner wall of the movable groove 4, ensuring the flexible movement of the movable plate 401 while preventing dust and debris from entering the movable groove 4, preventing it from affecting the smooth sliding of the support slider 501, and enhancing the sealing of the structure.

[0041] A fixing ring 22 is fixedly connected to the top outer wall of one of the support beams 2, a third motor 23 is installed inside the fixing ring 22, a lock buckle 24 is provided on the outer wall of the fixing ring 22, a reciprocating screw 25 is fixedly installed on the output end of the third motor 23, a connecting plate 26 is fixedly installed on the top outer wall of the other support beam 2, the outer wall of the other end of the reciprocating screw 25 is rotatably connected to the inner wall of the connecting plate 26, a movable block 6 is fixedly installed on the top outer wall of the mounting box 5, a through hole 601 is opened in the movable block 6, and the outer wall of the through hole 601 is movably connected to the reciprocating screw 25;

[0042] In this embodiment, the third motor 23 is firmly mounted on the support beam 2 via a fixing ring 22 and a lock 24, and its output end drives the reciprocating screw 25 to rotate, while the movable block 6 on the top of the mounting box 5 is threadedly connected to the reciprocating screw 25 via a through hole 601, forming a screw transmission mechanism. When the reciprocating screw 25 rotates, the movable block 6 moves along the axial direction of the screw, thereby driving the mounting box 5 to slide in the movable groove 4 via the support slider 501, thereby adjusting the horizontal position of the control seat 19. The connecting plate 26 supports and positions the other end of the reciprocating screw 25, ensuring its stability during rotation and preventing the screw from bending and deforming due to excessive cantilevering. This structure enables the control seat 19 to be accurately moved to the stator storage position or the paint dipping station, thereby improving the flexibility and accuracy of the operation.

[0043] The mounting box 5 is slidably connected to the two cross beams 3 through the provided movable groove 4 and the supporting slider 501, and the inner walls of the two first mounting plates 9 are rotatably connected to the corresponding rotating shaft 801. The two pairs of first mounting plates 9 and second mounting plates 12 are rotatably connected to the corresponding rope drum 10. The mounting box 5 is movably connected to the two cross beams 3 through the provided movable groove 4, the supporting slider 501, the elastic sealing frame 21, the compression spring 20 and the movable plate 401. The first motor 7 drives the transmission gear 8 to rotate, driving the driven gear 802 to rotate and control the steel rope 11 to retract and release, completing the up and down movement of the lifting control seat 19. The third motor 23 is fixedly connected to the fixing ring 22 through the provided lock buckle 24. The mounting box 5 is movably connected to the two cross beams 3 through the provided movable groove 4, the supporting slider 501, the elastic sealing frame 21, the compression spring 20, the movable plate 401, the third motor 23, the reciprocating screw rod 25 and the movable block 6. The third motor 23 drives the mounting box 5 to reciprocate between the two cross beams 3;

[0044] Working principle: Two cross beams 3 are arranged between the two support beams 2, a gap is left between the two cross beams 3, an installation box 5 is arranged between the gaps, a working compartment 502 is opened at the bottom of the installation box 5, and a first motor 7 is arranged on the outer wall of the installation box 5. When the first motor 7 is started, the transmission gear 8 inside the installation box 5 is driven to rotate. As the transmission gear 8 rotates, the driven gear 802 is driven to rotate. After the transmission gear 8 and the driven gear 802 rotate together, they respectively drive the rope drums 10 on the two rotating shafts 801 to rotate together. As the rope drum 10 rotates, the steel rope 11 drives the control seat 19 to slowly descend. At the same time, a hanging platform 18 is provided between the steel rope 11 and the control seat 19, which can be used to adjust the direction of the control seat 19 to facilitate the installation of the stator. At the same time, a second mounting plate 12 is provided at the rope drum 10, and a fixing plate 13 is fixedly provided on the outer walls of the two second mounting plates 12. An electric push rod 14 is provided. When the electric push rod 14 is started, the support plate 16 outside the control seat 19 is pushed to support the control seat 19, thereby ensuring the stability of the stator and effectively avoiding the problem that the center of gravity of the stator is shifted after the control seat 19 lifts the stator, thereby causing damage to the stator. A movable groove 4 is opened on the outer walls opposite to each other of the two cross beams 3, and compression springs 20 are provided at the bottom of the inner walls of the two movable grooves 4. A movable plate 401 is provided on the top of the two pairs of compression springs 20 for pressure buffering of the installation box 5 to ensure the stability of the stator during the hanging process. A third motor 23 is provided on the top of one of the support beams 2. When the third motor 23 is started, the movable block 6 is driven to move on the reciprocating screw rod 25. At the same time, the bottom of the movable block 6 is fixedly connected to the installation box 5. The movement of the movable block 6 can drive the installation box 5 to move, thereby adjusting the position of the control seat 19, which is convenient for the extraction of the stator.

[0045] Place the exciter stator to be dipped in paint steadily between the two limiting collars 1907. After it is properly placed, start the second motor 1902 to drive the bidirectional screw 1904 to rotate. Under the action of the bidirectional screw 1904, the two adjustment blocks 1903 threadedly connected thereto begin to approach each other along the screw. As the two adjustment blocks 1903 approach, the two limiting collars 1907 respectively connected thereto gradually approach and are tightly stuck on the inner wall of the stator, thereby achieving a firm clamping of the stator. When the stator is firmly clamped, start the first motor 7 to drive the transmission gear 8 inside the installation box 5 to rotate, and the transmission gear 8 then drives the driven gear 802 to rotate, thereby controlling the retraction and extension of the steel rope 11, thereby achieving a control seat 19 drives the stator down to the paint dipping position and starts the paint dipping operation. During the paint dipping process, when the angle of the stator needs to be adjusted, the shift block 1912 is pushed upward to drive the clamping block 1913 to disengage from the slot 1909 on the outer wall of the connecting ring 1908, and the connecting ring 1908 is no longer restricted by the clamping block 1913. Rotating the connecting ring 1908 can drive the limiting ring 1907 and the stator clamped by it to rotate together, thereby adjusting the angle of the stator to ensure that all parts of the stator can be evenly dipped in paint. After adjusting to the appropriate angle, release the shift block 1912, and the clamping block 1913 is reset under the elastic action of the elastic spring 1911 and re-locked into the corresponding slot 1909 to ensure the stability of the stator during the paint dipping process.
