[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following describes an oil-immersed transformer winding device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 3 As shown, the oil-immersed transformer winding device according to an embodiment of the present invention may include a driving structure 100 , a connecting column 200 , a reciprocating structure 300 , a guiding structure 400 , a knocking structure 500 and a supporting structure 600 .

[0027] The driving structure 100 and the connecting column 200 are arranged opposite to each other, and both ends of the iron core 700 are detachably connected to the driving structure 100 and the connecting column 200 respectively.

[0028] As a possible scenario, the drive structure 100 includes a motor and a transmission mechanism, wherein the transmission mechanism is detachably connected to the end of the iron core 700 through a flange, and can drive the iron core 700 to rotate through the transmission mechanism when driven by the motor.

[0029] The reciprocating structure 300 is erected between the driving structure 100 and the connecting column 200 . The guide structure 400 is disposed on the moving end of the reciprocating structure 300 . The flat copper wire 800 passes through the guide structure 400 and is wound around the iron core 700 .

[0030] The striking structure 500 is arranged above the iron core 700. Figure 2 As shown, the striking structure 500 includes a fixed shaft 510 and a striking plate 520 .

[0031] The fixed shaft 510 is disposed between the driving structure 100 and the connecting column 200 and is located above the iron core 700 . The knocking plate 520 is provided with a long sliding groove 521 which is slidably connected to the fixed shaft 510 .

[0032] It should be noted that the length of the slide groove 521 is greater than the cross-sectional diameter of the fixed shaft 510. As the number of layers of the flat copper wire 800 wrapped around the iron core 700 increases, the relevant staff can pull up the knocking plate 520 so that the knocking plate 520 can move upward.

[0033] In one embodiment of the present invention, the knocking plate 520 is provided with a handle 522 for easy pushing.

[0034] The support structure 600 is disposed at the bottom of the iron core 700 to compress the flat copper wire 800 wound around the iron core 700 .

[0035] It should be noted that the supporting end of the supporting structure 600 abuts against the flat copper wire 800 wound around the iron core 700 , and the length of the supporting end of the supporting structure 600 is smaller than the length of the iron core 700 .

[0036] Specifically, when the relevant staff is winding the flat copper wire 800, first, the relevant staff installs the two ends of the iron core 700 on the output end of the driving structure 100 and the rotating end of the connecting column 200 respectively, and after passing the flat copper wire 800 through the guide structure 400, it is initially wound around one end of the iron core 700, and the knocking plate 520 is pushed to the outside above the iron core 700 so that the knocking plate 520 does not contact the iron core 700.

[0037] Then, the relevant staff controls the supporting end of the supporting structure 600 to rise until it contacts the iron core 700.

[0038] Then the relevant staff starts the driving structure 100 and the reciprocating structure 300, and the iron core 700 rotates following the driving structure 100, and the guide structure 400 drives the flat copper wire 800 to move and wind along with the reciprocating structure 300. When the flat copper wire 800 becomes loosely wound, the relevant staff moves the knocking plate 520 to above the iron core 700 and pushes the knocking plate 520 horizontally so that the knocking plate 520 knocks on the side of the flat copper wire 800, thereby making the loose flat copper wire 800 become tighter.

[0039] In addition, when the iron core 700 rotates, the support structure 600 always compresses the flat copper wire 800 wound on the iron core 700 to prevent the flat copper wire 800 from spreading in a direction perpendicular to the axial direction. Through the cooperation of the knocking structure 500 and the support structure 600, the flat copper wire 800 can be wound more tightly.

[0040] In one embodiment of the present invention, Figure 4 As shown, the reciprocating structure 300 includes a driving motor 310 , a bidirectional lead screw 320 , a lead screw slider 330 , a stabilizing rod 340 and a sliding sleeve 350 .

[0041] Among them, a mounting frame 301 is provided on the driving structure 100 and the connecting column 200, the bidirectional screw 320 and the stabilizing rod 340 are respectively arranged between the two mounting frames 301, the bidirectional screw 320 is connected to the output end of the driving motor 310, the screw slider 330 is arranged on the bidirectional screw 320, and the sliding sleeve 350 is sleeved and slidably set on the stabilizing rod 340.

[0042] It should be noted that the guide structure 400 is arranged on the screw slider 330 and the sliding sleeve 350. When the relevant staff starts the reciprocating structure 300, the drive motor 310 is turned on, and the drive motor 310 drives the bidirectional screw 320 to rotate, so that the screw slider 330 moves on the bidirectional screw 320, and the guide structure 400 follows the screw slider 330 to move, and at the same time drives the sliding sleeve 350 to slide on the stabilizing rod 340.

[0043] In one embodiment of the present invention, the guide structure 400 includes a connecting plate 410 , a guide wheel frame 420 and a guide wheel 430 .

[0044] Among them, the connecting plate 410 connects the screw slider 330 and the sliding sleeve 350, the guide wheel frame 420 is set on the connecting plate 410, and the two guide wheels 430 are arranged relatively up and down in the guide wheel frame 420, wherein the flat copper wire 800 passes between the two guide wheels 430 and is wound around the iron core 700.

[0045] As a possible scenario, the guide structure 400 further includes a tensioning wheel, which is elastically disposed on the guide wheel frame 420 and is used to adjust the tension of the flat copper wire 800 .

[0046] After the relevant staff passes the flat copper wire 800 through the two guide wheels 430 and tensions it with the tensioning wheel, the tension of the flat copper wire 800 wound around the iron core 700 can be ensured.

[0047] In one embodiment of the present invention, Figure 5 As shown, the support structure 600 includes a driving cylinder 610 , a support frame 620 and a support roller 630 .

[0048] The supporting roller 630 is rotatably disposed on the supporting frame 620 , and the telescopic end of the driving cylinder 610 is connected to the supporting frame 620 .

[0049] It should be noted that the driving cylinder 610 can be set at an installation position such as the ground or other locations, and the specific installation position can be determined by relevant staff according to the on-site environment.

[0050] In addition, the driving cylinder 610 is a multi-stroke cylinder, that is, each time the flat copper wire 800 is wound one layer, the telescopic end of the driving cylinder 610 contracts accordingly.

[0051] In another embodiment of the present invention, the support structure 600 includes an elastic telescopic rod, a support frame 620 and a support roller 630 .

[0052] The support roller 630 is rotatably disposed on the support frame 620 , and the telescopic end of the elastic telescopic rod is connected to the support frame 620 .

[0053] As a possible situation, the elastic telescopic rod includes a rod sleeve, a top rod and a spring, wherein,

[0054] The push rod is slidably arranged in the rod sleeve, and the spring is arranged in the rod sleeve and connects the rod sleeve and the push rod. Under the elastic action of the spring, the support roller 630 always maintains contact with the flat copper wire 800 wound on the iron core 700, and there is no need to manually adjust the entire support structure 600.

[0055] In summary, according to the oil-immersed transformer winding winding device of the embodiment of the present invention, the relevant staff manually pushes and pulls the knocking plate 520, so that the knocking plate 520 can knock the flat copper wire 800, so that the flat copper wire 800 is arranged more tightly, and the flat copper wire 800 wound on the iron core 700 is compressed by the support structure 600 arranged at the bottom. Then, through the action of the knocking structure 500 and the support structure 600 in two directions, the flat copper wire 800 is wound on the iron core 700 and arranged more tightly, thereby improving the winding quality of the flat copper wire 800.
