Description

Technical Field

[0001] This utility model relates to the technical field of toroidal winding machines, specifically a wire storage ring for an ultra-high voltage transformer winding device. Background Technology

[0002] Currently, most current transformer windings employ the principle of first storing the wire and then releasing it. This means the wire storage ring first passes through the current transformer's magnetic ring from the opening, then the synchronous pulley locking ring is wound with sufficient enameled wire, and finally the coil is wound around the current transformer's magnetic ring in reverse. This method requires two processes: storing and releasing the wire. For example, storing the wire takes 1 hour, releasing and winding the coil takes 1.5 hours, and finally, winding takes 2.5 hours – this is the normal procedure. The disadvantages are the wasted time and the uncontrollable length of the stored wire, which can be tens of meters long or short. Longer wires are wasteful, while shorter ones are very troublesome (wiring, insulation, etc.). Therefore, it is time-consuming, labor-intensive, and material-intensive, and urgently needs a solution.

[0003] Application number 2021203457122, titled: Belt-type circular winding machine, which effectively improves winding speed, reduces manpower and material resources, and lowers processing costs.

[0004] Application number 2019222179943, entitled "A Wire Storage Ring for an Ultra-High Voltage Instrument Transformer Winding Device," comprises a large arc portion and a small arc portion. The inner ring is formed by the large arc segment and the small arc segment, which are concentric and detachably assembled onto the inner ring of the large arc portion and the small arc portion, respectively. This utility model not only facilitates replacement after wear but also saves replacement costs.

[0005] The aforementioned patent provides technical support for the wire storage ring of the toroidal winding machine, but it cannot provide technical support for subsequent wire release, because the wire storage ring only stores wire, but when wire needs to be released, it is released in the reverse direction. Utility Model Content

[0006] In order to achieve real-time buffering of winding equipment, this utility model proposes a wire storage ring for ultra-high voltage transformer winding equipment.

[0007] Therefore, the technical solution of this utility model is a wire storage ring for an ultra-high voltage transformer winding device. The wire storage ring includes a support frame. The support frame is a frame structure with an opening on one side. The frame structure is further divided into a front panel and a rear panel, and a connecting plate is provided on its upper part. A base is provided on the closed side. Front and rear support rings are provided on the front and rear panels respectively. The front and rear support rings are connected to each other by multiple support components to form a whole. Multiple synchronous pulleys are provided between the front and rear support rings. The multiple synchronous pulleys are evenly distributed and installed between the front and rear support rings, and the tangents on the rim surfaces of the multiple synchronous pulleys form a relative wire storage ring. A first drive motor is provided outside the base, and a first drive wheel is provided inside the base with the drive shaft of the first drive motor extending into the base. The first drive motor causes the first drive wheel to move. Between the front panel and the rear panel, there are also multiple driven wheels. Each driven wheel is fitted with a timing belt and is fitted with the first drive wheel. Finally, the belt is tightened by a tensioner. The described relationship between the outer surface of the synchronous belt and the wire storage ring formed by multiple synchronous pulleys.

[0008] The advantages are: The opening of the frame structure of this utility model is used for the intake of wires, and the upper part of the front panel and the rear panel, as well as the connecting plate and the unopened side are provided with a base, forming a frame structure that can help install the wire storage ring inside the frame structure. The drive shaft of the first drive motor outside the base extends into the base and is also provided with a first drive wheel. The first drive motor causes the first drive wheel to move. The synchronous belt and synchronous pulleys form the wire storage function of the wire storage ring. The stored wire rotates around multiple sets of synchronous pulleys under the drive of the synchronous belt, realizing the function of winding and storing wire at the same time, and is arranged in an orderly manner by being pressed by the synchronous belt.

[0009] The further improvement is that the front and rear support rings are respectively divided into a large arc and a small arc, and the opening two formed by the large arc and the small arc corresponds to the opening one of the frame structure. The outer sides of both ends of the large arc are provided with pressure plates and small arc segment locking pieces. The outer sides of both ends of the small arc are provided with locking spring strips. When the locking spring strips are inserted into the small arc segment locking pieces, they are pressed by the pressure plates to form the front and rear support rings.

[0010] The effect is that the front and rear support rings are designed with large and small arcs respectively, which is to prepare for the subsequent threading of the magnetic ring.

[0011] A further improvement is that the joint between the large and small arcs is a mortise and tenon structure, with the two ends of the large arc being set as dovetail groove female buckles and the two ends of the small arc being set as dovetail head male buckles.

[0012] The effect is that the mortise and tenon structure connects the large and small arcs to form a standard circle, which facilitates the storage of wires and makes clamping very convenient and neat.

[0013] A further improvement is that the cross-section of the synchronous pulley is an I-beam structure, a rotating shaft passes through the center of the synchronous pulley, bearings are fitted at both ends of the rotating shaft, and locking components are provided at both ends of the rotating shaft, so that it forms a moving synchronous pulley.

[0014] The effect is that the multiple wire storage rings formed by the synchronous pulleys can store the wires and arrange them in an orderly manner by being pressed together by the synchronous belt; the wire storage rings achieve real-time buffering and store the wires on the wire storage rings, which is convenient for subsequent winding.

Detailed Implementation

[0017] This utility model is as follows Figure 1-22 As shown: Example 1: Figure 1-5 As shown: The technical solution of this utility model applies to an ultra-high voltage transformer winding device, including a frame 6, on which a control system 1 is provided, and an iron core 4 is clamped on the frame 6 by an iron core active clamping seat assembly 7 and an iron core passive clamping seat assembly 8; the frame 6 has a lifting adjustment mechanism 5, wherein the lifting adjustment mechanism 5 is provided with a winding drive mechanism 2 and a wire storage ring 3. An automatic wire feeding mechanism 9 and a wire cutting mechanism 10 are also provided on the connecting plate 15 on the winding drive mechanism 2 and the wire storage ring 3.

[0018] This invention, through the combination of the winding drive mechanism 2 and the wire storage ring 3, enables wire storage and winding to proceed simultaneously, saving time and wire 12. In terms of working time, for example, simultaneous wire storage and winding only requires 1.5 hours. Furthermore, simultaneous wire storage and winding ensures that the length of the wire released is equal to the length of the wire stored, eliminating waste. When the length of the wire stored is greater than the length of the winding, the wire storage ring begins to store wire, and the winding drive mechanism consumes the stored wire to complete the winding. The active core clamping assembly 7 and the passive core clamping assembly 8 clamp the core 4, enabling the core 4 to be automatically centered and rotated. At this time, the winding drive mechanism 2 can evenly wind the core 4. The lifting and adjusting mechanism 5 achieves alignment with the center of the iron core; The wire-cutting mechanism 10 cuts the wire.

[0019] The lifting and adjusting mechanism 5 includes a mounting base 503, which is fixed to one side of the frame 6. The mounting base 503 is provided with a linear module 502, which is driven to move back and forth by a drive motor 501. The linear module 502 is mounted on a lifting base 504 and is driven by a lifting drive motor 506.

[0020] The lifting and adjusting mechanism 5 can adjust the positional relationship between the winding drive mechanism 2 and the wire storage ring 3 to achieve precise control.

[0021] The automatic wire feeding mechanism 9 is further provided with a wire laying mechanism 901 and a wire feeding mechanism 902, with the wire feeding mechanism 902 mounted on the wire laying mechanism 901; The cable laying mechanism 901 is driven by the cable laying motor 903, and the cable feeding mechanism 902 is driven by the cable feeding motor 904. A guide mechanism 11 is also provided on the wiring mechanism 901.

[0022] The cable arrangement mechanism 901 is driven by the cable arrangement motor 903, which can arrange the stored cables in an orderly manner; The implementation of the wire feeding mechanism 902 can pull out the wire 12 and form an active wire feeding, thus avoiding the breakage of the wire 12; The guiding mechanism 11 provides guidance for the storage line.

[0023] Example 2 Figure 6-18 As shown: This utility model applies to a wire storage and winding system of an ultra-high voltage transformer winding device. The wire storage ring 3 and the winding drive mechanism 2 include a support frame. The support frame is a frame structure with an opening on one side. The frame structure is further divided into a front panel 13 and a rear panel 14, and a connecting plate 15 is provided on its upper part. A base 16 is provided on the closed side. A front support ring 17 and a rear support ring 18 are respectively provided on the front panel 13 and the rear panel 14. The front support ring 17 and the rear support ring 18 are connected to each other through a support component 28 to form a whole. Multiple synchronous pulleys 19 are provided between the front support ring 17 and the rear support ring 18. The multiple synchronous pulleys 19 are evenly distributed and installed between the front support ring 17 and the rear support ring 18. The tangents on the rim surfaces of the multiple synchronous pulleys 19 form a relative wire storage ring 3. A first drive motor 20 is provided outside the base 16. The drive shaft of the first drive motor 20 extends into the base 16 and a first drive wheel 21 is also provided. The first drive motor 20 causes the first drive wheel 21 to move. Between the front panel 13 and the rear panel 14, there are also a number of driven wheels 22. A timing belt 25 is fitted on the multiple driven wheels 22 and is fitted with the first drive wheel 21. Finally, it is tightened by the tensioning wheel 24. The storage ring formed by the outer surface of the synchronous belt 25 and the multiple synchronous pulleys 19 has a mating relationship.

[0024] The opening of the frame structure of this utility model is used for the intake of the wire 12. The upper part of the front panel 13 and the rear panel 14, as well as the connecting plate 15 and the unopened side, are provided with a base 16 to form a frame structure that can help install the wire storage ring 3 inside the frame structure. The drive shaft of the first drive motor 20 outside the base 26 extends into the base 16 and a first drive wheel 21 is also provided. The first drive motor 20 causes the first drive wheel 21 to move. A mating relationship is formed between the outer surface of the synchronous belt 25 and multiple synchronous pulleys 19. At this time, the first drive motor 20 drives the first drive wheel 21 to drive the synchronous belt 25 to move circumferentially along the wire storage ring 3. The synchronous belt 25 and the synchronous pulley 19 form the wire storage function of the wire storage ring 3. The stored wire rotates around multiple sets of synchronous pulleys 19 under the drive of the synchronous belt 25, realizing the function of winding and storing wire at the same time, and is pressed and arranged in an orderly manner by the synchronous belt 25.

[0025] The winding drive mechanism 2 includes a front support ring 17 and a rear support ring 18. The inner diameter of the rear support ring 18 is provided with a front internal gear ring 26 and a rear internal gear ring 27, which form a synchronous gear set. A front gear 29 and a rear gear 30 are provided on the inner side of the front panel 13 and the rear panel 14. The front gear 29 and the rear gear 30 mesh with the front internal gear ring 26 and the rear internal gear ring 27, respectively. The front gear 29 is provided with a driven wheel 31 through the front panel 13 and is connected to a second drive wheel 34 through an inert gear 32. The second drive wheel 34 forms a driving relationship with the second drive motor 35. Multiple bearing support assemblies 33 are also provided in the extended portions of the front panel 13 and the rear panel 14; the multiple bearing support assemblies 33 and the supporting front support ring 17 and the rear support ring 18 form a support and movement relationship.

[0026] The winding drive mechanism 2 is driven by the second drive motor 35, which actively releases the wire wound on the wire storage ring 3 to achieve winding of the iron core 4. At this time, the wire storage ring 3 continuously stores wire, and the winding drive mechanism 2 winds the iron core 4 in real time, realizing the simultaneous storage and winding of wire, which solves the time problem in the background technology, saves at least 1 / 3 of the time, reduces the waste of wire, and solves the unreliability in the production process. The multiple bearing support assemblies 33 support the operation of the winding drive mechanism 2, and also provide directional support and movement for the front and rear support rings 17 and 18.

[0027] The front gear 29 and the rear gear 30 are each in sets of three or more; There are also more than three driven gears 31 and inertial gears 32 corresponding to the front gear 29. The inertial gears 32 directly or indirectly mesh with the second drive wheel 34 to form a kinematic relationship.

[0028] The front gear 29 and the rear gear 30 are in more than three sizes to ensure stability during the driving process of the second motor; Driven by the front gear 29 and engaged by the rear gear 30, the winding drive mechanism 2 enables active wire feeding.

[0029] An annular guide rail 36 is also provided on the inner extension plate of the rear panel 14. A spring mechanism 37 is also provided on the annular guide rail 36. The spring mechanism 37 moves in annular motion along the annular guide rail 36. A guide wheel 38 is also provided on the annular guide rail 36. The spring of the spring mechanism 37 is guided by the guide wheel 38 to move along the annular guide rail.

[0030] The spring mechanism 37 moves in a ring along a section of annular guide rail 36 and is guided by the guide wheel 38 to move along the annular guide rail, so that the wire of the wire storage ring 3 is wound on the iron core 4 by the winding drive mechanism 2. Because the diameter of the iron core 4 is not on the same center as the circumference of the wire release, the spring mechanism 37 can keep the wire 12 actively released by the winding drive mechanism 2 under tension, so that it does not become tangled and is arranged in an orderly manner.

[0031] The front support ring 17 and the rear support ring 18 are further divided into a large circular arc 1701 and a small circular arc 1702, respectively. The second opening formed by the large circular arc 1701 and the small circular arc 1702 corresponds to the first opening of the frame structure. The outer sides of both ends of the large arc 1701 are provided with pressure plates 1703 and small arc segment locking pieces 1704. The outer sides of both ends of the small arc 1702 are provided with locking spring strips 1705. When the locking spring strips 1705 are inserted into the small arc segment locking pieces 1704, they are pressed by the pressure plates 1703 to form the front support ring 17 and the rear support ring 18.

[0032] The front support ring 17 and the rear support ring 18 are respectively divided into large arc and small arc open-type designs; this is to prepare for the subsequent threading of the iron core 4.

[0033] The joint between the large arc 1701 and the small arc 1702 is a mortise and tenon structure, wherein the two ends of the large arc 1701 are set as dovetail groove female buckles 1706, and the two ends of the small arc 1702 are set as dovetail head female buckles 1707.

[0034] The mortise and tenon structure connects the large arc 1701 and the small arc 1702 into a standard circle through the connection of the female and male fasteners, which facilitates the storage of wires 12 and makes the clamping process very convenient and neat.

[0035] The synchronous pulley 19 has an I-shaped cross-section. A rotating shaft 1901 passes through the center of the synchronous pulley 19. Bearings 1902 are fitted at both ends of the rotating shaft 1901, and locking components 1903 are provided at both ends of the rotating shaft 1901 to form a moving synchronous pulley.

[0036] The multiple wire storage rings 3 formed by the synchronous pulleys 19 can store the wires 12 and arrange them in an orderly manner by being pressed together by the synchronous belt 25; the wire storage rings 3 realize real-time buffering and store the wires 12 on the wire storage rings 3 for convenient use in subsequent winding.

[0037] The principle of the storage winding system: such as Figure 19-22 As shown: In this invention, the iron core 4 is wound with a diameter of 800mm in one turn, and the wire storage ring 3 is wound with a diameter of 3140mm in one turn. The diameter of the wire storage ring 3 in one turn is nearly four times that of the iron core 4. The wire storage ring 3 and the winding drive mechanism 2 are on the same wheel. While the winding drive mechanism 2 is winding the iron core 4, the wire storage ring 3 stores many turns of wire 12 (enameled wire), that is, the (enameled wire) is wound around the circumference of the wire storage ring 3, which is composed of multiple synchronous pulleys 19. The synchronous belt 25 cooperates with multiple driven pulleys 22. The first drive motor 20 drives the synchronous belt 25, which drives the synchronous pulleys 19 to rotate the wire storage ring 3. The multiple turns of wire 12 (enameled wire) wound around the synchronous pulleys 19 will generate rolling friction. In this way, the wire 12 (enameled wire) will not be broken while winding and storing wire, so that the function of simultaneous wire storage and winding can be achieved.

[0038] In the winding drive mechanism 2, the wire 12 (enameled wire) is pulled inward from the synchronous pulley 19. The spring mechanism 37 moves in a ring along a section of annular guide rail 36 and is guided by the guide wheel 38 to move along the annular guide rail, so that the wire 12 of the wire storage ring 3 is wound on the iron core 4 through the winding drive mechanism 2. Because the diameter of the iron core 4 is not on the same center as the circumference of the wire release, the spring mechanism 37 can keep the wire 12 actively released by the winding drive mechanism 2 under tension, prevent it from getting tangled, and keep it arranged in an orderly manner.

[0039] At this time, the wire storage and winding are in the same direction, so that the wire storage ring 3 stores the wire while the iron core 4 is wound, saving time and wire 12. In terms of working time, for example, the wire storage and winding can be carried out simultaneously, which only takes 1.5 hours. Also, the wire storage and winding can be carried out simultaneously so that the length of the wire released is equal to the length of the wire stored, and there is no waste. When the length of the wire stored is greater than the length of the winding, the wire storage ring starts to store the wire, and the winding drive mechanism 2 will consume the stored wire to realize the winding.
