[0002] Currently, when winding the transformer winding of oil-immersed power transformers above 110 kV on the market, generally, the paper-covered wire is wound around a separate winding mold to form a transformer winding. After winding, the winding is dried. After drying, the winding is compressed. Finally, the winding is sleeved, and the insulating parts between the winding and the iron core and between the windings are assembled in place, then the winding operation of the oil-immersed power transformer above 110 kV can be completed.

[0003] When the existing transformer winding device winds the transformer winding, the winding mold is installed on the driving shaft, the wire feeding end feeds the wire, and the driving shaft drives the winding mold to rotate and wind the paper-covered wire around the winding mold; During the winding process of the existing transformer winding device, the equipment generates severe vibration due to the operation of the driving component. The vibration will cause the loosening of the wire feeding end or the winding component, resulting in an uneven rotation speed between the driving shaft and the wire feeding end, thus causing the paper-covered wire to be loose on the winding mold and unable to fit tightly on the winding mold, thereby causing problems such as a decline in winding quality and a decline in the electrical performance of the transformer.

Subsequently, the first electric cylinder is driven to work, causing the guide wheel to drive the paper-covered wire to descend and traction, and controlling the tension of the paper-covered wire to avoid the problem of the wire drooping freely to the ground during wire retraction.

[0020] Next, the technical solution of a transformer winding device in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-14 shown, the present invention provides: a transformer winding device, including a bottom plate 1, a machine shell 2 is fixedly connected to the bottom plate 1, a reciprocating movement mechanism 3 and a placing mechanism 50 for fixing a winding mold are arranged inside the machine shell 2, and a guide assembly 40 is arranged on the reciprocating movement mechanism 3; The guide assembly 40 includes a fixed block 41, the fixed block 41 is fixedly connected with a connecting plate 42 through an elastic member, a guide wheel 43 for guiding a paper-covered wire is rotatably connected inside the connecting plate 42 through a first driving mechanism, several top plates 431 are slidably connected inside the guide wheel 43, and a driving member for driving the top plates 431 to slide is arranged inside the connecting plate 42; As Figure 3 shown, the reciprocating movement mechanism further includes a reciprocating lead screw 31 rotatably connected inside the machine shell 2, a moving plate 32 is threadedly connected to the reciprocating lead screw 31, a positioning rod 36 is slidably connected to the inner wall of the moving plate 32, the positioning rod 36 and one side of the machine shell 2 are fixedly connected, the inside of the moving plate 32 and one side of a slide rail 33 are fixedly connected, and the inner wall of the moving plate 32 and the fixed end of a first electric cylinder 35 are fixedly connected; As Figure 1 shown, the placing mechanism 50 includes a driving rod 51 rotatably connected inside the machine shell 2, a clamping plate 52 is threadedly connected to the driving rod 51, and the winding mold placed on the driving rod 51 is clamped and fixed by the clamping plate 52; As Figure 7 、 Figure 13 and Figure 14As shown in the figure, the driving member includes a rotating rod 443 rotatably connected to the connecting plate 42. A cam 44 is fixedly connected to the rotating rod 443. A circumferential portion 441 is provided on the surface of the cam 44. A convex portion 442 is provided on one side of the circumferential portion 441. The diameter of the convex portion 442 is greater than the diameter of the circumferential portion 441. The paper-covered wire is guided by the guide wheel 43 and wound around the surface of the winding die. Subsequently, the first driving mechanism drives the guide wheel 43 to rotate. The guide wheel 43 drives a plurality of top plates 431 to rotate synchronously. The top plates 431 rotate around the driving member. After the paper-covered wire detaches from the top plates 431, the top plates 431 are squeezed by the driving member and slide towards the outer wall of the guide wheel 43, so that the top plates 431 are in contact with the outer wall of the guide wheel 43 and contact and squeeze the paper-covered wire wound around the surface of the winding die, making the paper-covered wire fit more tightly with the surface of the winding die.

[0022] Specifically, during the winding process of the existing transformer winding device, the equipment vibrates violently due to the operation of the driving components. The vibration will cause the loosening of the wire feeding end or the winding part, resulting in an uneven rotation speed between the driving shaft and the wire feeding end, thus causing the paper-covered wire to become loose on the winding die and unable to fit tightly on the winding die, resulting in problems such as a decline in winding quality and a decline in the electrical performance of the transformer. The reciprocating lead screw 31 and the driving rod 51 in this device are both connected to the driving components inside the machine shell 2. The driving components are prior art. The driving components can drive the reciprocating lead screw 31 and the driving rod 51 to rotate on the outer wall of the machine shell 2. To solve the above existing problems, the present invention is used as follows: Place the winding die on the driving rod 51 and rotate the clamping plate 52 to fix the winding die on the driving rod 51. Subsequently, pass the paper-covered wire on the wire feeding end through the inner groove of the guide wheel 43 and wind it around the surface of the winding die. Then the winding operation can be carried out. The driving components inside the machine shell 2 work and immediately drive the reciprocating lead screw 31 and the driving rod 51 to rotate. The driving rod 51 rotates and drives the winding die to rotate, so that the paper-covered wire is wound around the surface of the winding die. At the same time, the reciprocating lead screw 31 drives the moving plate 32 to reciprocate on the positioning rod 36. The moving plate 32 drives the connecting plate 42 to reciprocate synchronously. The connecting plate 42 drives the guide wheel 43 to reciprocate. The guide wheel 43 drives the paper-covered wire inside its groove to reciprocally wind around the surface of the winding die, making the paper-covered wire evenly wound around the surface of the winding die. When the paper-covered wire is in the inner groove of the guiding wheel 43, the first driving component inside the connecting plate 42 drives the guiding wheel 43 to rotate synchronously. The guiding wheel 43 drives several internal top plates 431 to rotate synchronously. The multiple top plates 431 rotate around the cam 44. Initially, when the top plate 431 rotates to the circumferential part 441 of the cam 44, the top plate 431 is received in the groove of the guiding wheel 43. At this time, the paper-covered wire is in the inner groove of the guiding wheel 43 and contacts the upper surface of the top plate 431. After the paper-covered wire separates from above the top plate 431, one end of the top plate 431 rotates to the convex part 442 of the cam 44. The top plate 431 is squeezed by the convex part 442 of the cam 44, causing the top plate 431 to slide outward to the outer wall of the guiding wheel 43 and the top plate 431 to fit against the outer wall of the guiding wheel 43. Subsequently, the guiding wheel 43 drives the top plate 431 to rotate synchronously and contacts and squeezes the paper-covered wire wound on the surface of the winding die, so that the paper-covered wire is tightly wound on the surface of the winding die; By arranging the guiding wheel 43, the device can drive the paper-covered wire to reciprocate and be evenly wound on the surface of the winding die. The reciprocating motion of the guiding wheel 43 can accurately control the arrangement trajectory of the paper-covered wire, making each layer of winding tight and evenly distributed, ensuring a more uniform magnetic field distribution of the winding coil, thereby improving the electrical performance of the transformer. At the same time, by driving the top plate 431 to rotate through the guiding wheel 43, the top plate 431 moves and fits against the outer wall of the guiding wheel 43, enabling the guiding wheel 43 to squeeze the paper-covered wire. Therefore, the paper-covered wire can be evenly and tightly wound on the winding die, effectively preventing the loosening of the paper-covered wire during the winding process.

[0023] As Figure 4 shown, the elastic member includes a spring telescopic rod 411 fixedly connected inside the fixed block 41. The telescopic end of the spring telescopic rod 411 is fixedly connected to the inside of the connecting plate 42, and the fixed end of the spring telescopic rod 411 is fixedly connected to the inside of the fixed block 41.

[0024] Specifically, when the number of layers of the paper-covered wire on the surface of the winding die increases, the diameter of the winding die changes at this time. Therefore, when the guiding wheel 43 moves on the surface of the paper-covered wire, the paper-covered wire squeezes the guiding wheel 43, causing the guiding wheel 43 to drive the connecting plate 42 to move synchronously. The connecting plate 42 squeezes the spring telescopic rod 411 inside the fixed block 41, enabling the guiding wheel 43 to automatically adjust its position according to the change in the number of layers of the paper-covered wire to perform squeezing operations on the paper-covered wire and the surface of the winding die.

[0025] As Figures 8-11 shown, the first driving mechanism includes a motor 421 fixedly connected inside the connecting plate 42. The output end of the motor 421 is fixedly connected with a first gear 422. The rotating end of the guiding wheel 43 is fixedly connected with a second gear 432. The second gear 432 meshes with the first gear 422.

[0026] When it is necessary to drive the guide wheel 43 to rotate, the motor 421 can be turned on. The motor 421 drives the first gear 422 to rotate. The first gear 422 meshes with the second gear 432, so that the second gear 432 can drive the guide wheel 43 synchronously. The rotation of the guide wheel 43 can drive the top plate 431 to rotate synchronously.

[0027] As Figure 7 and Figure 14 shown, a sleeve 45 is fixedly connected inside the guide wheel 43. The sleeve 45 is slidably connected to the top plate 431. A first spring 451 is fixedly connected between the surface of the top plate 431 and the inner wall of the sleeve 45.

[0028] Specifically, when the top plate 431 is squeezed by the convex portion 442 of the cam 44, the top plate 431 slides inside the sleeve 45 and squeezes the first spring 451. When the top plate 431 moves to the circumferential portion 441 of the cam 44, the first spring 451 drives the top plate 431 to reset, so that one end of the top plate 431 fits on the circumferential portion 441 of the cam 44.

[0029] As Figures 8-11 shown, a limiting rod 6 is rotatably connected to the outer wall of the machine shell 2. The height of the limiting rod 6 is the same as the horizontal height of the driving rod 51. One end of the rack 424 is provided with a second electric cylinder 423. The fixed end of the second electric cylinder 423 is fixedly connected to the inside of the connecting plate 42. The telescopic end of the second electric cylinder 423 is fixedly connected to one end of the rack 424. The surface of the cam 44 is slidably connected to one end of the top plate 431. The upper surface of the top plate 431, one side of the connecting plate 42 and one side of the guide wheel 43 are all inclined.

[0030] As Figure 3 shown, the reciprocating movement mechanism 3 includes a slide rail 33. A slider 34 is slidably connected to the slide rail 33. A first electric cylinder 35 is arranged below the slider 34. The telescopic end of the first electric cylinder 35 is fixedly connected to the lower part of the slider 34. The inside of the slider 34 is fixedly connected to the surface of the fixed block 41.

[0031] Specifically, during the winding process of the winding die, when the winding speed is fast and there are phenomena such as over-tight, over-loose or irregular winding, it is necessary to unwind the paper-covered wire and rewind it. When the winding device reverses to unwind the wire, it is necessary to adjust the tension between the driving rod 51 and the wire feeding end to avoid the problem that the paper-covered wire will sag freely and contact the ground, causing damage to the surface of the paper-covered wire. When the above-mentioned guide wheel 43 is used for tension adjustment, it is necessary for the staff to manually place the paper-covered wire from above the guide wheel 43 to below the guide wheel 43, and limit the paper-covered wire through the groove of the guide wheel 43, and the ejector rod will push the paper-covered wire into the inside of the groove, resulting in the problem of the paper-covered wire falling off; To avoid the above technical problems, the present device operates as follows: When it is necessary to unwind the paper-covered wire, the guide wheel 43 is kept fixed, and the second electric cylinder 423 can be driven to operate. The second electric cylinder 423 drives the rack 424 to slide in the direction of the bottom side of the axial connection plate 42, so that the rack 424 meshes with the third gear 444. The third gear 444 drives the rotating rod 443 to rotate, and the rotating rod 443 drives the cam 44 to rotate, causing the cam 44 to rotate 180 degrees. At this time, the circumferential portion 441 of the cam 44 faces downward, and the initial position faces upward. When the cam 44 rotates, it pushes the top plate 431 to rotate, and the top plate 431 slides outward from the guide wheel 43, so that the top plate 431 pushes the paper-covered wire to slide outward from the guide wheel 43. Since the length of the paper-covered wire is relatively long when it is payed out, the paper-covered wire slides on the inclined surface of the top plate 431, and then slides to the inclined surfaces of the connection plate 42 and the guide wheel 43, causing the paper-covered wire to automatically fall below the guide wheel 43. Subsequently, the user opens the first electric cylinder 35, and the first electric cylinder 35 drives the slider 34 to slide on the slide rail 33. The slider 34 drives the fixed block 41 to slide downward, so that the guide wheel 43 slides downward. Then, the paper-covered wire is placed in the groove of the guide wheel 43. One end of the paper-covered wire is above the limit rod 6, and one end is on the winding die. The middle part is driven downward by the guide wheel 43, so that the downward movement of the guide wheel 43 controls the tension of the paper-covered wire. When unwinding the wire, the guide wheel 43 drives the paper-covered wire to reciprocate for unwinding and winding. Subsequently, when the guide wheel 43 drives the ejector rod to rotate, at this time, the convex portion 442 of the cam 44 faces upward, so the ejector rod will not contact the paper-covered wire below and push it out of the groove. After the wire unwinding is completed, the cam 44 is driven to reset. At this time, the top plate 431 pushes the paper-covered wire out of the groove of the guide wheel 43. Then, the reciprocating lead screw 31 is driven to drive the guide wheel 43 to retreat, and the first electric cylinder 35 is driven to adjust the position of the guide wheel 43, so that the paper-covered wire is in the upper groove of the guide wheel 43, and the winding operation can be continued; The present device drives the guide wheel 43 to slide up and down through the first electric cylinder 35, thereby adjusting the tension of the paper-covered wire during wire unwinding, avoiding the problem that the paper-covered wire will sag freely and contact the ground, causing damage to the surface of the paper-covered wire. At the same time, the paper-covered wire can be automatically adjusted below the guide wheel, reducing the labor intensity of manual operation and improving work efficiency.

[0032] Working principle: First, prepare the winding mold for the oil-immersed power transformer. Then, place the winding mold on the driving rod 51 and rotate the clamping plate 52 to fix the winding mold on the driving rod 51. Subsequently, pass the paper-covered wire at the wire-releasing end through the inner groove of the guide wheel 43 and wind it around the surface of the winding mold. Then, the winding operation can be carried out. The driving component inside the machine shell 2 works and immediately drives the reciprocating lead screw 31 and the driving rod 51 to rotate. The driving rod 51 rotates and drives the winding mold to rotate, causing the paper-covered wire to wind around the surface of the winding mold. At the same time, the reciprocating lead screw 31 drives the moving plate 32 to reciprocate on the positioning rod 36. The moving plate 32 drives the connecting plate 42 to reciprocate synchronously. The connecting plate 42 drives the guide wheel 43 to reciprocate. The guide wheel 43 drives the paper-covered wire inside its groove to reciprocally wind around the surface of the winding mold, making the paper-covered wire evenly wind around the surface of the winding mold; When the paper-covered wire is in the inner groove of the guide wheel 43, turn on the motor 421. The motor 421 drives the first gear 422 to rotate. The first gear 422 meshes with the second gear 432, enabling the second gear 432 to drive the guide wheel 43 synchronously. The guide wheel 43 drives several internal top plates 431 to rotate synchronously. The multiple top plates 431 rotate around the cam 44. Initially, when the top plate 431 rotates to the circumferential part 441 of the cam 44, the top plate 431 is received in the groove of the guide wheel 43. At this time, the paper-covered wire is in the inner groove of the guide wheel 43 and contacts the upper surface of the top plate 431. After the paper-covered wire separates from above the top plate 431, one end of the top plate 431 rotates to the convex part 442 of the cam 44. The top plate 431 is squeezed by the convex part 442 of the cam 44, causing the top plate 431 to slide outward from the guide wheel 43 and the outer wall of the top plate 431 to fit with the outer wall of the guide wheel 43. Subsequently, the guide wheel 43 drives the top plate 431 to rotate synchronously and performs contact and extrusion operations on the paper-covered wire wound on the surface of the winding mold, making the paper-covered wire tightly wind around the surface of the winding mold; When the number of layers of the paper-covered wire on the surface of the winding mold increases, the diameter of the winding mold changes at this time. Therefore, when the guide wheel 43 moves on the surface of the paper-covered wire, the paper-covered wire squeezes the guide wheel 43, causing the guide wheel 43 to drive the connecting plate 42 to move synchronously. The connecting plate 42 squeezes the spring telescopic rod 411 inside the fixed block 41, enabling the guide wheel 43 to automatically adjust its position according to the change in the number of layers of the paper-covered wire to perform extrusion operations on the paper-covered wire and the surface of the winding mold; When the unwinding treatment of the paper-covered wire is required, keep the guide wheel 43 fixed, and the second electric cylinder 423 can be driven to work. The second electric cylinder 423 drives the rack 424 to slide in the bottom side direction of the axial connecting plate 42, so that the rack 424 meshes with the third gear 444. The third gear 444 drives the rotating rod 443 to rotate, and the rotating rod 443 drives the cam 44 to rotate, so that the cam 44 rotates to 180 degrees. At this time, the circumferential part 441 of the cam 44 faces downward, and the initial position faces upward. When the cam 44 rotates, it pushes the top plate 431 to rotate, and the top plate 431 slides outward from the guide wheel 43, so that the top plate 431 pushes the paper-covered wire to slide outward from the guide wheel 43. Since the length of the paper-covered wire is long when it is payed out, the paper-covered wire slides on the inclined surface of the top plate 431, and then slides to the inclined surfaces of the connecting plate 42 and the guide wheel 43, so that the paper-covered wire automatically falls below the guide wheel 43. Subsequently, the user opens the first electric cylinder 35, and the first electric cylinder 35 drives the slider 34 to slide on the slide rail 33. The slider 34 drives the fixed block 41 to slide downward, so that the guide wheel 43 slides downward. Then the paper-covered wire is placed in the groove of the guide wheel 43. One end of the paper-covered wire is above the limiting rod 6, and one end is on the winding die. The middle part is driven downward by the guide wheel 43, so that the downward movement of the guide wheel 43 controls the tension of the paper-covered wire. When unwinding, the guide wheel 43 drives the paper-covered wire to reciprocate for unwinding and winding treatment. Subsequently, when the guide wheel 43 drives the ejector rod to rotate, at this time, the convex part 442 of the cam 44 faces upward, so the ejector rod will not contact the paper-covered wire below and push it out of the groove. After the unwinding is completed, the cam 44 is driven to reset. At this time, the top plate 431 pushes the paper-covered wire out of the groove of the guide wheel 43. Then the reciprocating lead screw 31 is driven to drive the guide wheel 43 to retreat, and the first electric cylinder 35 is driven to adjust the position of the guide wheel 43, so that the paper-covered wire is in the upper groove of the guide wheel 43, and the winding operation can be continued.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
