[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] The core is an important structure of a transformer, mainly consisting of the core column and the yoke. The core column is the main magnetic circuit part of the transformer, and usually consists of multiple silicon steel sheets stacked together to achieve magnetic circuit closure.

[0034] The tightness of the silicon steel sheets stacked in the core column directly affects the overall performance and stability of the transformer. Clamping the core column ensures the integrity of the magnetic conductor, reduces eddy current losses and no-load current, thereby improving the efficiency and reliability of the transformer.

[0035] Currently, for iron core columns with a semi-circular cross-section, a semi-circular fixture is usually made of laminated wood. This semi-circular fixture is then spliced ​​with the iron core column to form a circular frame. Cable ties are then wrapped around the outside of the circular frame along the axial direction of the iron core column to clamp the iron core column.

[0036] However, the semi-circular tooling made of laminated wood is heavy, making it difficult for operators to lift and hold. To address this issue, this application discloses a clamping device for a core column. This device is simple in structure, lightweight, and does not require manual lifting, thus reducing the operator's workload.

[0037] like Figure 1 As shown, the clamping device for the iron core column disclosed in this application includes: a tooling body and an arc-shaped slider 3. The tooling body includes a first assembly 1 and a second assembly 2. The first assembly 1 includes: a main body 11, a connecting rod 12 and an upper hanging plate 13. The second assembly 2 includes: a telescopic rod 21, a lower hanging plate 22 and a guide guard plate 23.

[0038] The fixture body has an upper hanging plate 13 at one end along the first direction and a lower hanging plate 22 at the other end along the first direction. The upper hanging plate 13 and the lower hanging plate 22 are arranged opposite to each other and parallel to each other along the first direction. In this article, the first direction refers to the axial direction of the core column, and the second direction refers to the radial direction of the core column. For other locations mentioned in the article, please refer to this description.

[0039] The upper mounting plate 13 and the lower mounting plate 22 are arranged opposite each other along the first direction. During the clamping process of the clamping device clamping the core column, the upper mounting plate 13 is attached to the upper surface of the core column along the axial direction, and the lower mounting plate 22 is attached to the lower surface of the core column along the axial direction. By using the upper mounting plate 13 and the lower mounting plate 22 to clamp the core column along the first direction, the clamping connection between the clamping device and the core column is realized.

[0040] The curved slider 3 is connected to the main body of the tooling and is located between the two ends of the main body of the tooling along the first direction. The curved surface of the curved slider 3 protrudes in the second direction relative to the main body of the tooling. Optionally, the curved slider 3 is located between the upper hanging plate 13 and the lower hanging plate 22. Of course, the curved slider 3 can also be flush with the upper hanging plate 13 and / or the lower hanging plate 22 to support the tightening band at the upper hanging plate 13 and the lower hanging plate 22, thereby improving the roundness of the tightening band. It should be noted that the position of the curved slider 3 can be set according to the position of the upper hanging plate 13 and the lower hanging plate 22, and the installation position of the curved slider 3 is always within the protection range.

[0041] Optionally, the connecting rod 12 and the arc surface slider 3 correspond one-to-one. The number of connecting rods 12 can be set according to different needs and can be arranged along the first direction. The arc surface slider 3 is distributed along the arc surface.

[0042] The curved slider 3 protrudes in the second direction and, together with the iron core column, forms a structure with a circular cross-section. That is, the curved slider 3 supports the tightening band along the second direction, so that the tightening band wraps around the outside of the iron core column in the plane of the first direction. This can be understood as the tightening band wrapping around the upper surface, lower surface, and side surface of the iron core column along the first direction.

[0043] During the clamping process of the core column: the upper hanging plate 13 can be suspended on the upper surface of the core column, and the lower hanging plate 22 can be placed on the lower surface of the core, flush with the lower surface; the upper hanging plate 13 and the lower hanging plate 22 are used to connect the clamping device to the core column. The tightening band wraps around the outside of the semi-circular section of the core column in the first direction, and the tightening band passes through the arc-shaped slider 3 during the wrapping process, so that the tightening band is wrapped in a ring. The jack and the screw jack are placed on the upper surface of the upper hanging plate 13, and the two ends of the tightening band are wrapped around the tightening band and the semi-circular section core. The horizontal support of the arc-shaped slider 3 is adjusted to ensure that the angle of the tightening band on both sides of the jack is consistent. The jack provides clamping force for tightening the tightening band. For example, the screw jack is set to a pressure of 5 tons, and the semi-circular core is pre-clamped evenly, realizing the clamping of the stacked plates of the semi-circular section core column.

[0044] Optionally, a tightening strap can be tied every 300mm to clamp the semi-circular cross-section core columns. During the transformer core clamping process, each column is clamped to ensure that the lamination coefficient meets the requirements, ultimately guaranteeing good no-load loss and noise reduction performance of the core.

[0045] The clamping device of this application embodiment can suspend the main body of the tooling on the iron core during use, without the need for manual support of the clamping device. Therefore, it can help reduce the difficulty of operation and thus reduce the labor intensity of the operator.

[0046] In an optional embodiment, both the tooling body and the curved slider 3 can be formed from square steel. The hollow interior of the square steel helps reduce weight; furthermore, the high strength of the square steel meets the strength requirements of the tooling body.

[0047] The curved slider 3 supports the tightening belt along the second direction and provides pre-tension to the tightening belt. Only the outline needs to be set, and there is no need to set the overall structure. Therefore, it is beneficial to simplify the structure and reduce the weight of the clamping device.

[0048] It should be noted that current semi-circular clamping devices made of laminated wood require two people to clamp the semi-circular iron core column. Specifically, each iron core column needs to be tightened with 10 tensioning straps. During the tightening process, one operator needs to lift the 22kg laminated wood fixture while the other operator tightens the tensioning straps wrapped around the laminated wood fixture and the iron core column. As can be seen from the above work process, using laminated wood fixtures requires a large number of operators, and the operators' labor intensity is high. In contrast, the clamping device proposed in this application only requires hanging a 10kg clamping device on the iron core column, and only one operator is needed to tighten the semi-circular side yoke, which can reduce the number of operators and reduce the operators' labor intensity.

[0049] Combination Figure 1 As can be seen, the first mounting component 1 and the second mounting component 2 are arranged along the first direction. The upper mounting plate 13 is located at the end of the main body 11 away from the second mounting component 2, and the lower mounting plate 22 is located at the end of the telescopic rod 21 away from the first mounting component 1. It should be noted that the installation positions of the upper mounting plate 13 and the lower mounting plate 22 include, but are not limited to, the positions disclosed above. The figure only illustrates one specific position and does not constitute a specific limitation. Optionally, the upper mounting plate 13 may be located in the middle of the main body 11, and the lower mounting plate 22 may be located in the middle of the telescopic rod 21.

[0050] A connecting rod 12 is provided at one end of the main body 11 near the first assembly 1, and an arc-shaped slider 3 is provided at the end of the connecting rod 12 away from the main body 11. Optionally, the size of the connecting rod 12 along the second direction can be set according to different needs, and all are within the protection range.

[0051] The connecting rod 12 is arranged close to the first assembly 1, which can increase the angle of the tensioning band along the first direction on the upper surface near the core column, which is beneficial for the pre-tightening force of the jack to be transmitted through the tensioning band in the winding direction.

[0052] In some embodiments, the distance between the upper mounting plate 13 and the lower mounting plate 22 along the first direction is adjustable.

[0053] By adjusting the distance between the upper hanging plate 13 and the lower hanging plate 22 along the first direction, the main body of the tooling can be inserted into iron core columns of different sizes along the first direction, that is, the main body of the tooling can be adapted to iron core columns of different sizes along the first direction.

[0054] like Figures 2 to 6 As shown in the embodiment of this application, a method is disclosed to make the distance between the upper mounting plate 13 and the lower mounting plate 22 adjustable along the first direction. Specifically, the distance between the upper mounting plate 13 and the lower mounting plate 22 is adjusted by the relative movement of the first mounting part 1 and the second mounting part 2.

[0055] in, Figures 2 to 4 The first assembly 1 includes: a main body 11, a connecting rod 12, and an upper hanging plate 13.

[0056] One end of the main body 11 along the first direction is fixedly connected to the upper hanging plate 13, and the other end of the main body 11 along the first direction has a mounting groove that extends along the first direction. The shape and size of the mounting groove can be set according to different needs, and all are within the protection range.

[0057] The main body 11 has a first locking hole 111 and a fastening hole 112.

[0058] The first locking hole 111 and the fastening hole 112 are distributed along the first direction. Optionally, the first locking hole 111 may include, but is not limited to, a plurality of first locking holes 111, and the plurality of first locking holes 111 may be distributed along the first direction.

[0059] The first locking hole 111 and the fastening hole 112 extend through the mounting groove in a direction perpendicular to the first direction. The first locking hole 111 is, but is not limited to, an oblong hole that extends in the first direction; the fastening hole 112 is, but is not limited to, a round hole, and optionally a threaded hole.

[0060] The first locking hole 111 is an oblong hole, which allows for fine adjustment of the position of the first assembly 1 and the second assembly 2 along the first direction, ensuring that the distance between the upper hanging plate 13 and the lower hanging plate 22 is more compatible with the size of the core column along the first direction.

[0061] The aforementioned fastening hole 112 is not required during the connection process of the first assembly 1 and the second assembly 2. If the fastening hole 112 happens to have a corresponding second locking hole 211 of the second assembly 2, the fastening hole 112 can be connected to the second locking hole 211.

[0062] The connecting rod 12 is arranged perpendicularly to the main body 11. Optionally, the connecting rod 12 and the main body 11 may be integrally formed or welded together.

[0063] The connecting rod 12 has a first mounting hole 121. Optionally, there are multiple first mounting holes 121, arranged along a second direction. In some embodiments, the first mounting holes 121 are evenly arranged along the second direction. Of course, the spacing between adjacent first mounting holes 121 along the second direction can be set differently according to different needs.

[0064] The first mounting hole 121 may be, but is not limited to, a round hole; optionally, the first mounting hole 121 may be a threaded hole.

[0065] like Figure 5 and Figure 6 As shown, the second assembly 2 includes: a telescopic rod 21, a lower hanging plate 22, and a guide guard plate 23.

[0066] The telescopic rod 21 is inserted into the mounting groove of the main body 11 and can move along the mounting groove. The telescopic rod 21 has a second locking hole 211, which may include, but is not limited to, a plurality of second locking holes, arranged along a first direction. Optionally, the second locking holes 211 are evenly distributed along the first direction, or the distance between adjacent second locking holes 211 along the first direction is different.

[0067] In this embodiment, the telescopic rod 21 is detachably connected to the main body 11, and during the movement of the telescopic rod 21 along the mounting groove, the telescopic rod 21 moves relative to the main body 11 in a first direction, thereby adjusting the distance between the upper hanging plate 13 and the lower hanging plate 22 in the first direction.

[0068] In order to fix the telescopic rod 21 to the main body 11 in the first direction, different second locking holes 211 can be connected to the first locking hole 111 to change the position of the telescopic rod 21 relative to the main body 11.

[0069] Optionally, the first locking hole 111 and the second locking hole 211 are fixedly connected by a locking member (not shown in the figure), thereby achieving a fixed connection between the telescopic rod 21 and the main body 11. The locking member includes, but is not limited to, threaded parts such as bolts.

[0070] The above content discloses the telescopic connection method of the second mounting part 2 relative to the first mounting part 1, so as to realize the adjustment of the distance between the upper hanging plate 13 and the lower hanging plate 22. In other optional embodiments, the first mounting part 1 and the second mounting part 2 can also be connected by threads to form a screw and nut structure. By rotating the second mounting part 2, the position of the second mounting part 2 on the first mounting part 1 changes, thereby realizing the adjustment of the distance between the upper hanging plate 13 and the lower hanging plate 22.

[0071] In some embodiments, Figure 1 and Figure 2A limiting member 113 may also be provided on the main body 11. The limiting member 113 may include, but is not limited to, a bolt. The limiting member 113 is threadedly connected to the main body 11 and extends into the mounting groove of the main body 11. The limiting member 113 can abut against the telescopic rod 21.

[0072] By rotating the limiting member 113, the contact force between the limiting member 113 and the telescopic rod 21 can be adjusted, so that the telescopic rod 21 abuts against the side wall of the mounting groove, thereby limiting the telescopic rod 21 along the first direction. Figure 1 and Figure 2 The structure of the limiting member 113 is only shown in the figure, and the position of the limiting member 113 is not specifically limited.

[0073] The lower mounting plate 22 is located at the end of the telescopic rod 21 away from the first assembly 1. Optionally, the lower mounting plate 22 and the telescopic rod 21 are integrally formed, including but not limited to.

[0074] The guide plate 23 is located at the end of the telescopic rod 21 away from the first assembly 1. The guide plate 23 is an arc-shaped plate that guides the second assembly 2 away from the first assembly 1 toward the arc-shaped slider 3. The guide plate 23 guides the tightening belt, allowing the tightening belt to pass around the clamping device more smoothly and reducing wear between the tightening belt and the clamping device.

[0075] Optionally, the guide plate 23 and the telescopic rod 21 may be integrally formed, including but not limited to.

[0076] In some embodiments, there are at least two guide plates 23, arranged along a guiding direction perpendicular to the guide plates 23, and there is a gap between adjacent guide plates 23. Optionally, there are two guide plates 23, arranged along a third direction, and the third direction, the second direction, and the first direction are perpendicular to each other.

[0077] The two adjacent guide plates 23 have a gap along the third direction to accommodate the tightening belt 4. By using the guide plates 23 to limit the tightening belt 4 along the third direction, it can prevent the tightening belt 4 from shifting along the third direction and affecting the tightening effect of the tightening belt 4.

[0078] In some embodiments, the guide plate 23 is an arc plate. Setting the guide plate 23 as an arc plate can increase the roundness of the tightening band, improve the stress on the tightening band at various points, and facilitate the improvement of the clamping effect of the tightening band on the core column.

[0079] Combination Figure 1 as well as Figure 7 and Figure 8 As shown, the distance between the arc-shaped slider 3 and the tooling body in the second direction disclosed in this application embodiment is adjustable.

[0080] By adjusting the distance between the arc-shaped slider 3 and the fixture body, the distance between the arc-shaped slider 3 and the fixture body can be changed, allowing the clamping device to adapt to iron core columns with different dimensions along the second direction. Combined with the movement of the arc-shaped slider 3 relative to the fixture body and the movement of the second assembly 2 relative to the first assembly 1, the clamping device can be dimensionally adjusted in both the vertical and horizontal directions according to the diameter of the iron core column, adapting to iron core columns of different sizes and different binding angles of the clamping straps.

[0081] like Figure 7 and Figure 8 As shown, the curved slider 3 includes: a connector 31, a reinforcing rib 32, and a curved support plate 33.

[0082] The connector 31 is used to be detachably connected to the connecting rod 12 of the first assembly 1. Specifically, the connector 31 has a second assembly hole 311, which is detachably connected to the first assembly hole 121 of the connecting rod 12.

[0083] Based on the dimensions of the core column along the second direction, the connector 31 selects the first mounting hole 121 on the connecting rod 12 and aligns the second mounting hole 311 with the first mounting hole 121. The connector is then locked with the first mounting hole 121 and the second mounting hole 311 using a threaded component, thereby achieving a detachable and fixed connection between the arc-shaped slider 3 and the tooling body.

[0084] In some embodiments, the connector 31 has, but is not limited to, two second mounting holes 311 arranged along a second direction.

[0085] By setting multiple second assembly holes 311, the distance that the arc-shaped slider 3 and the tooling body can move along the second direction can be increased, further expanding the applicability of the clamping device.

[0086] Optionally, the connector 31 may be made of square steel, and the connector 31 may be hollow to reduce its weight. The dimension of the curved support plate 33 along the third direction is the same as that of the connector 31 along the third direction, so as to increase the width of the curved support plate 33 along the third direction, increase the contact area of ​​the curved support plate 33 with the tightening belt, and prevent the tightening belt from separating from the curved support plate 33 after movement.

[0087] In this embodiment of the application, the arc-shaped support plate 33 is connected to the connector 31 by a reinforcing rib 32, and the dimension of the reinforcing rib 32 along the third direction is smaller than the dimension of the arc-shaped support plate 33 along the third direction.

[0088] Reducing the dimension of the reinforcing rib 32 along the third direction can reduce the amount of reinforcing rib 32 used and lower the weight of the clamping device. Optionally, the reinforcing rib 32 is located at the middle position of the curved support plate 33 along the third direction.

[0089] The clamping device described in this application embodiment can save the following volume of laminated wood for semi-circular yokes of different diameters: 118cm * 59cm * 5cm = 34810cm². 3 ; Single unit of 10 pieces of laminated wood: 34810cm 3 *10=348100cm 3 Savings in laminated wood cost: 0.3481m 3 *1.1t / m 3 *15000 yuan / t = 5740 yuan. Producing 30 semi-circular side yoke iron cores annually saves on the cost of processing laminated wood tooling: 574 yuan / unit * 100 units / year = 172200 yuan / year.

[0090] In addition: Previously, when binding and tightening the straps, one person was needed to hold the laminated wood block while another tightened it, requiring two people to work together. Now, only one person is needed to clamp the semi-circular iron core, improving production efficiency. Each product saves one person, and clamping one unit takes 4 hours. With 100 units per year, the labor cost savings are: 1 person * 4 hours * 10 yuan / hour * 100 units / year = 4000 yuan / year.

[0091] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0092] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
