The threads on a screw 15 have opposite rotation directions; two threaded sleeves 16 rotatably mounted on the rectangular steel tube 12, the two threaded sleeves 16 are respectively threadedly sleeved on the two first screws 15, so that when the threaded sleeves 16 rotate, the corresponding two first screws 15 are moved away from or closer to each other, thereby making the two steel plates 13 move away from or closer to each other; two worm wheels 17 are respectively fixedly sleeved on the two threaded sleeves 16; a second fixed plate 18 is fixedly mounted on one end of the rectangular steel tube 12 away from the first fixed plate 11; a worm 19 rotatably mounted on the first fixed plate 11 and the second fixed plate 18, the worm 19 is meshed with the two worm wheels 17, and a handwheel is fixedly mounted on one end of the worm 19 for rotating the worm 19.

The rectangular steel pipe 12 has excellent strength and stability, and provides a stable support structure for the winding process; two steel plates 13 are symmetrically arranged just above and just below the rectangular steel pipe 12. The two steel plates 13 are bent into a U shape to support the high-voltage coil carrier; protective plates 14 are fixedly installed on the top, bottom and both sides of the steel plate 13.

One end thereof passes through the through hole on the support plate 81, which is convenient for connection with the linkage assembly 5. The moving seat 44 is threadedly sleeved on the reciprocating screw rod 43 and slidably sleeved on the two first limiting rods 42. When the reciprocating screw rod 43 rotates, the moving seat 44 will reciprocate along the first limiting rod 42. The first rectangular frame 45 is fixedly mounted on one side of the moving seat 44, and the U-shaped frame 46 is slidably mounted on the inner walls of both sides of the first rectangular frame 45. Two guide rollers 47 are respectively rotatably sleeved on the U-shaped frame 46 and the two mounting shafts, and an annular groove is opened on their outer walls to guide the winding process of the high-voltage coil. The second screw rod 48 is arranged on one side of the U-shaped frame 46 and is threadedly connected with the first rectangular frame 45. By turning the knob, the position of the U-shaped frame 46 in the first rectangular frame 45 can be adjusted, and then the spacing of the guide rollers 47 can be adjusted. The limiting block 49 ensures the stability of the U-shaped frame 46 during the adjustment process. The main function of the linkage assembly 5 is to drive the reciprocating screw rod 43 to rotate under the power of the driving assembly 3, thereby realizing the automatic movement of the moving assembly 4. In this way, when the driving assembly 3 is started, the reciprocating screw rod 43 will also rotate accordingly, thereby driving the moving seat 44 and the winding structure thereon to reciprocate, thereby realizing the automatic winding of the high-voltage coil.
[0053] Through the coordinated use of the moving component 4 and the linkage component 5, the high-voltage coil winding device of the present invention not only improves the winding efficiency, but also reduces the difficulty of operation, making the entire winding process more automated and intelligent.
[0054] In a further preferred embodiment of the present invention, the linkage assembly 5 includes: a main sprocket 51 fixedly mounted on the rotating shaft 34; a hexagonal rod 52 arranged at one end of the reciprocating screw rod 43 and integrally formed with the reciprocating screw rod 43; a transmission sprocket group 53 mounted on the hexagonal rod 52, the transmission sprocket group 53 is composed of transmission sprockets of multiple diameters arranged side by side, and when the transmission sprocket group 53 rotates, it can drive the hexagonal rod 52 to rotate, thereby driving the reciprocating screw rod 43 to rotate, and under external force, the transmission sprocket group 53 can slide along the axial direction of the hexagonal rod 52; a chain 54 meshing on the main sprocket 51 and one of the transmission sprockets on the transmission sprocket group 53.
[0055] In this embodiment, the design of the linkage assembly 5 cleverly realizes the power transmission between the drive assembly 3 and the mobile assembly 4. First, the main sprocket 51 is fixedly sleeved on the rotating shaft 34. This means that when the main motor 31 in the drive assembly 3 is started and drives the rotating shaft 34 to rotate, the main sprocket 51 will also rotate synchronously. Next, the hexagonal rod 52 is a part integrally formed with the reciprocating screw rod 43, which is located at one end of the reciprocating screw rod 43. This design not only enhances the stability of the structure, but also simplifies the path of power transmission. The transmission sprocket group 53 is a special structure composed of multiple transmission sprockets of different diameters arranged side by side. These sprockets are sleeved on the hexagonal rod 52 and can slide along the axial direction of the hexagonal rod 52 under the action of external force. This design allows the transmission sprocket group 53 to adjust its position as needed to adapt to different working environments and requirements. The chain 54 is a key transmission element in the linkage assembly 5. It is engaged with the main sprocket 51 and a transmission sprocket in the transmission sprocket group 53, thereby realizing the transmission of power from the main sprocket 51 to the transmission sprocket group 53. When the main sprocket 51 rotates, the transmission sprocket set 53 can be driven to rotate accordingly through the transmission of the chain 54. Since the transmission sprocket set 53 is connected to the hexagonal rod 52, when the transmission sprocket set 53 rotates, the hexagonal rod 52 and the reciprocating screw rod 43 integrally formed therewith are driven to rotate together. In this way, the power of the driving component 3 is successfully transmitted to the moving component 4 through the linkage component 5, thereby realizing the driving of the reciprocating screw rod 43. The design of this linkage component 5 is not only compact in structure and high in transmission efficiency, but also has greater flexibility.
[0056] In a further preferred embodiment of the present invention, a switching assembly 6 is provided on one side of the support plate 81, which is used to switch the use of a transmission sprocket of corresponding specifications in the transmission sprocket group 53 when winding copper wires of different diameters. The switching assembly 6 includes: a fixed block 61 fixedly mounted on one side of the support plate 81, a second limit rod 62 fixedly mounted on one side of the fixed block 61, and a scale line is provided on the second limit rod 62; a connecting block 63 fixedly mounted on one end of the second limit rod 62; a second screw 64 rotatably mounted on the connecting block 63 and the fixed block 61, and the second screw 64 and the second limit rod 6 2 are arranged in parallel, and a knob is also fixedly installed at one end of the second screw rod 64; a first adjusting block 65 is slidably sleeved on the second limiting rod 62 and threadedly sleeved on the second screw rod 64; an inverted U-shaped plate 66 is fixedly installed at the bottom of the first adjusting block 65, and movable holes are opened on both sides of the inverted U-shaped plate 66, and the hexagonal rod 52 passes through the two movable holes. The transmission sprocket group 53 is located between the inner walls on both sides of the inverted U-shaped plate 66, and annular grooves are opened on the inner walls on both sides of the inverted U-shaped plate 66. A plurality of balls are arranged in the annular grooves, and the balls in the two annular grooves are in rolling contact with the two sides of the transmission sprocket group 53 respectively.
[0057] In this embodiment, the design of the switching assembly 6 provides great convenience for the operator when winding copper wires of different diameters, so that the transmission sprocket of the corresponding specification in the transmission sprocket group 53 can be easily switched. In the switching assembly 6, the fixed block 61 is firmly mounted on one side of the support plate 81, and the second limit rod 62 is fixed thereon. The second limit rod 62 is provided with scale lines, which provide the operator with accurate adjustment references to ensure that the transmission sprocket group 53 can be accurately moved to the desired position. The connecting block 63 is fixed to one end of the second limit rod 62, and together with the fixed block 61, it constitutes a rotation support for the second screw rod 64. The second screw rod 64 is arranged parallel to the second limit rod 62, and one end of the second screw rod 64 is also provided with a knob for convenient manual adjustment by the operator. The first adjustment block 65 is slidably sleeved on the second limit rod 62, and is threadedly sleeved on the second screw rod 64. By rotating the knob of the second screw rod 64, the first adjustment block 65 can be accurately moved along the second limit rod 62. The inverted U-shaped plate 66 is fixed to the bottom of the first adjustment block 65, and movable holes are provided on both sides of the inverted U-shaped plate 66, so that the hexagonal rod 52 can pass through them. The transmission sprocket set 53 is located between the inner walls on both sides of the inverted U-shaped plate 66, so that the transmission sprocket set 53 can move with the movement of the inverted U-shaped plate 66. Annular grooves are also provided on the inner walls on both sides of the inverted U-shaped plate 66, and multiple balls are installed in the grooves. These balls are in rolling contact with the two sides of the transmission sprocket set 53, which greatly reduces friction and improves the efficiency and stability of transmission.
[0058] The working process of the switching component 6: When it is necessary to wind copper wires of different diameters, the operator first observes the scale line on the second limit rod 62 to determine the position that needs to be adjusted. Then, by rotating the knob of the second screw 64, the first adjustment block 65 is driven to move along the second limit rod 62, thereby driving the inverted U-shaped plate 66 and the transmission sprocket group 53 therein to move to the appropriate position. In this process, the presence of the ball ensures that the transmission sprocket group 53 can move smoothly without being subjected to excessive friction resistance. Once the transmission sprocket group 53 moves to the correct position, the operator can connect it to the main sprocket 51 through the chain 54, thereby establishing a path for power transmission. At this time, the power of the drive component 3 can be transmitted to the moving component 4 through the linkage component 5, driving the reciprocating screw 43 to rotate, thereby realizing the automatic winding of the high-voltage coil.
[0059] The design of the switching assembly 6 not only improves the convenience of operation, but also ensures the accuracy and stability of transmission through the use of precise scale lines and balls, providing reliable support for the winding of high-voltage coils.
[0060] It should be noted that, when the corresponding transmission sprocket is used, when the carrier rotates one circle, the movable seat 44 moves a distance corresponding to the diameter of the copper wire used, thereby achieving tight and uniform winding of the coil.
[0061] In a further preferred embodiment of the present invention, a tension adjustment component 7 for adjusting the tension of the chain 54 is also installed on one side of the support plate 81, so as to be able to smoothly switch different transmission sprockets, and the tension adjustment component 7 includes: a second rectangular frame 71 fixedly installed on one side of the support plate 81, and third limit rods 72 are fixedly installed on the inner walls of both sides of the second rectangular frame 71; a bidirectional screw 73 rotatably installed on the inner walls of both sides of the second rectangular frame 71, and the bidirectional screw 73 is provided with two sections of threads with opposite rotation directions, and a knob is also fixedly installed on one end of the bidirectional screw 73; two symmetrically arranged second adjustment blocks 74 threadedly sleeved on the bidirectional screw 73 and slidably sleeved on the third limit rod 72, and the two second adjustment blocks 74 are rotatably installed with wheel axles 75; two adjustment sprockets 76 fixedly sleeved on the two wheel axles 75, respectively, and the two adjustment sprockets are engaged with the chain 54.
[0062] In this embodiment, in order to better adapt to the transmission sprockets of different specifications and ensure the smooth transmission of the chain, a tension adjustment component 7 is specially designed. The component is not only simple in structure, but also easy to adjust, which effectively improves the transmission efficiency and the convenience of operation. The structure of the tension adjustment component 7: the second rectangular frame 71 is firmly mounted on one side of the support plate 81, providing a stable support foundation for the tension adjustment component 7. The third limit rod 72 is fixedly mounted on the inner walls of both sides of the second rectangular frame 71, which plays a guiding and limiting role to ensure stability during the adjustment process. The bidirectional screw 73 is rotatably mounted on the inner walls of both sides of the second rectangular frame 71, and is characterized in that it has two sections of threads with opposite rotation directions. This design enables the two second adjustment blocks 74 threadedly sleeved thereon to move toward or away from each other when the bidirectional screw 73 rotates. The second adjustment block 74 is not only threadedly sleeved on the bidirectional screw 73, but also slidably sleeved on the third limit rod 72, ensuring the stability and accuracy of the movement. A wheel axle 75 is rotatably mounted on each second adjusting block 74, and an adjusting sprocket wheel 76 is fixedly sleeved on the wheel axle 75. The two adjusting sprocket wheels 76 are all engaged with the chain 54, and the tightness of the chain 54 can be effectively adjusted by their rotation.
[0063] The working process of the tension adjustment component 7:
[0064] When the tightness of the chain 54 needs to be adjusted, the operator only needs to rotate the knob at one end of the bidirectional screw 73. Since the bidirectional screw 73 has two sections of threads with opposite rotation directions, the two second adjustment blocks 74 will move toward or away from each other when rotated. In this way, by adjusting the distance between the two adjustment sprockets 76, the tightness of the chain 54 can be accurately adjusted. After the adjustment is completed, the chain 54 will maintain an appropriate tension state, ensuring that when switching between transmission sprockets of different specifications, the chain can smoothly mesh between the main sprocket 51 and the transmission sprocket group 53 to achieve effective power transmission.
[0065] The use of the tension adjustment assembly 7 not only simplifies the adjustment process and improves work efficiency, but also ensures the stability and reliability of the transmission system. This is of great significance for the automation and precision operation of high-voltage coil winding equipment.
[0066] In a further preferred embodiment of the present invention, two mounting blocks 91 are fixedly sleeved on one of the first limit rods 42, and trigger buttons 92 are installed on the sides of the two mounting blocks 91 close to each other, which are used to shut down the main motor 31 when the moving seat 44 moves to the farthest point on both ends of the reciprocating screw rod 43.
[0067] In this embodiment, in order to ensure that the main motor 31 can be automatically shut down when the movable seat 44 moves to the farthest end on the reciprocating screw 43, thereby preventing the equipment from being overloaded or damaged, a trigger button 92 is specially provided as an innovative mechanism. The following is a structural and functional description of the mechanism: The first limit rod 42 and the mounting block 91: Two mounting blocks 91 are fixedly sleeved on one of the first limit rods 42. The positions of the two mounting blocks 91 are carefully designed to ensure that they can accurately sense the moving state of the movable seat 44. Trigger buttons 92 are installed on the sides of the two mounting blocks 91 that are close to each other. These buttons are set to be activated under specific conditions, that is, when the movable seat 44 moves to the farthest point at both ends of the reciprocating screw 43.
[0068] How trigger button 92 works:
[0069] When the moving seat 44 moves to the farthest point on the reciprocating screw 43, it will touch the trigger button 92. Once this touch occurs, the trigger button 92 will be activated, thereby sending a signal to the controller. After receiving this signal, the controller will immediately perform the preset operation - shut down the main motor 31, and start the alarm to remind the worker to perform subsequent operations. This design effectively avoids equipment overload or damage caused by the continued movement of the moving seat 44, ensuring the stability and safety of the entire system.
[0070] It is worth noting that the circuits, electronic components and modules involved in the present invention are all prior art, and those skilled in the art can fully implement them. Needless to say, the content protected by the present invention does not involve improvements to software and methods.
[0071] The present solution also provides a controller, which is disposed on the device. When in use, each electrical device can be started and operated separately through the controller. The power connection method of each electrical device is an existing mature technology, which is a well-known technology to those skilled in the art and will not be elaborated on here.
[0072] The present invention also provides a winding method for an oil-immersed transformer high-voltage coil winding device, the winding method is applied to the above-mentioned oil-immersed transformer high-voltage coil winding device, the winding method comprises the following steps:
[0073] S1, remove the baffle 25 in the copper wire mounting frame assembly 2, sleeve the copper wire roll 23 to be wound on the reel 21, then install the baffle 25 on the first screw rod 24, and tighten the nut to make it tightly against the baffle 25;
[0074] S2, then the high-voltage coil carrier is sleeved on the protective plate 14 located on the periphery of the winding adjustment frame assembly 1, and the hand wheel is turned to rotate the worm 19, so that the two steel plates 13 drive the upper and lower protective plates 14 away from each other, so that the upper and lower protective plates 14 tightly support the high-voltage coil carrier;
[0075] S3, passing the starting end of the copper wire of the copper wire roll 23 through the first rectangular frame 45, so that the copper wire is located between the two guide rollers 47, and winding the starting end of the copper wire on the high-voltage coil carrier and fixing it;
[0076] S4. Turn the knob on the second screw rod 48 to rotate the second screw rod 48 and push the U-shaped frame 46 to move. The two limit blocks 49 slide in the limit holes on the first rectangular frame 45. The U-shaped frame 46 drives the guide roller 47 thereon to move toward the other guide roller 47 until the copper wire is restricted between the two guide rollers 47.
[0077] S5, start the main motor 31, reduce the speed through the reduction gear box 32, and drive the winding adjustment frame assembly 1 to rotate through the rotating shaft 34, so that the high-voltage coil carrier rotates with the winding adjustment frame assembly 1, and then continuously winds the copper wire on the high-voltage coil carrier. At the same time, the rotating shaft 34 drives the reciprocating screw rod 43 to rotate through the linkage assembly 5, so that the moving seat 44 moves laterally along the reciprocating screw rod 43, and then drives the two guide rollers 47 to move laterally. The guide rollers 47 can carry the copper wire to move laterally. For each rotation of the high-voltage coil carrier, the moving seat 44 moves a distance of the copper wire diameter, so that the copper wire can be tightly and evenly wound on the high-voltage coil carrier;
[0078] S6. When the movable seat 44 moves from one end to the other end and touches the trigger button 92, the main motor 31 is turned off and the alarm sounds, so that the staff can promptly cover a layer of insulating paper on the wound copper coil. After the paper covering operation is completed, the main motor 31 is started again, and the movable seat 44 moves in the reverse direction to continue winding the copper wire on the high-voltage coil carrier until the entire winding work is completed. The hand wheel is rotated in the reverse direction to release the fixing of the high-voltage coil carrier by the protective plate 14, and then the high-voltage coil carrier with the copper coil wound on it is removed from the protective plate 14;
[0079] S7. When copper wires of different diameters are needed, the corresponding transmission sprocket needs to be switched, that is, the knob at one end of the bidirectional screw 73 is first turned to rotate it, so that the two second adjustment blocks 74 are close to each other, thereby loosening the chain 54, and then the knob on the second screw 64 is turned to rotate it, thereby driving the first transmission adjustment block 65 to move, thereby driving the transmission sprocket group 53 to move through the inverted U-shaped plate 66, and moving the appropriate distance according to the scale line, and then the chain 54 is sleeved on the corresponding transmission sprocket directly above the main sprocket 51, and then the bidirectional screw 73 is turned in the opposite direction to move the two second adjustment blocks 74 away from each other until the chain 54 is tightened, and then the winding operation can be performed according to steps S1-S6.
[0080] In summary, compared with the related art, the present invention facilitates the installation and fixing of the high-voltage coil carrier by setting the winding adjustment frame assembly 1, and by setting the moving assembly 4 and the linkage assembly 5, the driving assembly 3 can drive the reciprocating screw rod 43 in the moving assembly 4 to rotate while driving the carrier to rotate, thereby realizing the horizontal movement of the copper wire, so that the coil can be tightly and evenly wound;
[0081] Furthermore, by providing the switching component 6 and the tension adjustment component 7, the transmission sprocket of the corresponding specification can be switched to be used according to the diameter of the copper wire used, which is relatively simple to operate, improves production efficiency, and reduces labor intensity.

A winding method for a high voltage coil winding device of an oil immersed transformer, characterized in that: The winding method is applied to the oil-immersed transformer high-voltage coil winding device according to any one of claims 1 to 8, and the winding method comprises the following steps: S1, remove the baffle (25) in the copper wire mounting frame assembly (2), sleeve the copper wire roll (23) to be wound on the reel (21), then install the baffle (25) on the first screw rod (24), and tighten the nut to make it tightly against the baffle (25); S2, then sleeve the high-voltage coil carrier on the protective plate (14) located on the outer periphery of the winding adjustment frame assembly (1), and rotate the hand wheel to rotate the worm (19), so that the two steel plates (13) drive the upper and lower protective plates (14) away from each other, so that the upper and lower protective plates (14) tightly support the high-voltage coil carrier; S3, passing the starting end of the copper wire of the copper wire roll (23) through the first rectangular frame (45), so that the copper wire is located between the two guide rollers (47), and winding the starting end of the copper wire on the high-voltage coil carrier; S4. Turn the knob on the second screw rod (48) to rotate the second screw rod (48) and push the U-shaped frame (46) to move. The two limit blocks (49) slide in the limit holes on the first rectangular frame (45). The U-shaped frame (46) drives the guide roller (47) thereon to move toward the other guide roller (47) until the copper wire is confined between the two guide rollers (47). S5, starting the main motor (31), reducing the speed through the reduction gear box (32), and driving the winding adjustment frame assembly (1) to rotate through the rotating shaft (34), so that the high-voltage coil carrier rotates along with the winding adjustment frame assembly (1), and the copper wire is continuously wound on the high-voltage coil carrier. At the same time, the rotating shaft (34) drives the reciprocating screw rod (43) to rotate through the linkage assembly (5), so that the moving seat (44) moves laterally along the reciprocating screw rod (43), and then drives the two guide rollers (47) to move laterally. The guide rollers (47) can carry the copper wire to move laterally. For each rotation of the high-voltage coil carrier, the moving seat (44) moves a distance of a copper wire diameter, so that the copper wire can be tightly and evenly wound on the high-voltage coil carrier; S6. When the movable seat (44) moves from one end to the other end and touches the trigger button (92), the main motor (31) is shut down and the alarm sounds, so that the staff can promptly cover the wound copper coil with a layer of insulating paper. After the paper covering operation is completed, the main motor (31) is started again, and the movable seat (44) moves in the reverse direction to continue winding the copper wire on the high-voltage coil carrier until the entire winding operation is completed. The hand wheel is rotated in the reverse direction to release the protection plate (14) from fixing the high-voltage coil carrier, and then the high-voltage coil carrier with the copper coil wound on it is removed from the protection plate (14); S7. When copper wires of different diameters are required, the corresponding transmission sprockets need to be switched. That is, the knob at one end of the bidirectional screw (73) is first turned to rotate it so that the two second adjustment blocks (74) are moved closer to each other, thereby loosening the chain (54). The knob on the second screw (64) is then turned to rotate it, thereby driving the first transmission adjustment block (65) to move, thereby driving the transmission sprocket assembly (53) to move an appropriate distance according to the scale line, and then the chain (54) is sleeved on the corresponding transmission sprocket just above the main sprocket (51). The bidirectional screw (73) is then turned in the opposite direction to move the two second adjustment blocks (74) away from each other until the chain (54) is tightened. Then, the winding operation can be performed according to steps S1-S6.
