Description

Technical Field

[0001] The utility model belongs to the technical field of transformer manufacturing equipment, and in particular relates to a dry-type transformer iron core sheet taking-out device. Background Art

[0002] The assembly of dry-type transformers is to first stack the cut silicon steel core on the bracket, so that the vertically stacked core sheets form a core column, and then stack the core sheets horizontally on the top of the core column, so that the horizontally placed core sheets are connected to the top of each core column. Then the high and low voltage coils are assembled. In this process, in order to reduce the transfer of core sheets and brackets, all the required core sheets are first installed on the bracket, and then transferred to the assembly station as a whole, and then the high and low voltage coils are assembled. When assembling the high and low voltage coils, it is necessary to remove the core sheets stacked on the top of the core column, and then put the high and low voltage coils on the core column in turn, and then put the core sheets back.

[0003] When removing the existing iron core sheets, a part of the stacked iron core sheets are separated first, and then two workers hold the two ends of the separated iron core sheets respectively and then remove the iron core and place it on the workbench. This process is repeated many times to remove all the iron core sheets installed on the top of the iron core column, and then the high and low voltage coils are installed into the iron core column in turn, and then the iron core sheets are stacked back. In this process, the iron core sheets are heavy and the labor intensity of manual moving is high. In addition, the iron core sheets are very thin and are easy to slip when they are not held firmly, resulting in deformation of the iron core sheets and the risk of injuring workers.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a dry-type transformer iron core extraction device, comprising: a frame 100 and an extraction portion 200, wherein the extraction portion 200 is arranged to move along the frame 100 in the vertical direction to adapt to iron core columns of different heights.

[0024] Specifically, the frame 100 includes a base 110 . Universal wheels are provided at the bottom of the base 110 for easy transfer, and a column 120 is vertically provided on the top surface of the base 110 .

[0025] The taking-out part 200 includes a lifting plate 210, a group of material taking components 220, and a group of limiting components 230. The lifting plate 210 is a rectangular structure, and one side of its long side protrudes outward to be provided with a connecting seat, which is slidably connected to the column 120. The material taking components 220 are arranged at intervals along the length direction of the lifting plate 210, and the two material taking components 220 can be moved along the length direction of the lifting plate 210 to adapt to the iron core columns with different spacings. The material taking components 220 include a transverse plate 221, one end of the transverse plate 221 is movably arranged along the length direction of the lifting plate 210, and the other end extends out of the other side of the lifting plate 210. The limiting component 230 is arranged at the protruding end of the transverse plate 221, which is used to limit the iron core piece 1 when taking out the iron core piece 1.

[0026] Specifically, Figure 2 As shown, a lifting slot 121 is provided along the vertical direction of the column 120, a first motor 123 is provided at the top of the column 120, a screw rod 122 is provided at the output end of the first motor 123, the upper end of the screw rod 122 is connected to the output end of the first motor 123, and the connecting seat of the lifting plate 210 is connected to the screw rod 122 and slidably cooperates with the lifting slot 121. When the iron core piece 1 is taken out, the lifting plate 210 has good stability to prevent the lifting plate 210 from falling along the lifting slot 121 under the gravity of the iron core piece 1.

[0027] Specifically, Figure 2 As shown, two groups of T-slots 211 are symmetrically provided on the top surface of the lifting plate 210, and two T-seats 222 are provided on the bottom surface of one end of the transverse plate 221. The T-seats 222 slide in cooperation with the T-slots 211 to ensure a firm connection between the transverse plate 221 and the lifting plate 210, thereby improving the stability of the support of the transverse plate 221 when taking out the iron chip 1.

[0028] A second motor 212 is provided on the lifting plate 210, and a bidirectional screw rod 213 is provided at the output end of the second motor 212. A connecting hole is provided on the transverse plate 221, and the connecting hole is located between the two T-shaped seats 222. The connecting holes are respectively connected to the threaded sections of the bidirectional screw rod 213, so that the rotation of the second motor 212 drives the bidirectional screw rod 213 to rotate, thereby adjusting the spacing between the two transverse plates 221 to meet the needs of iron core columns of different widths, thereby expanding the scope of application.

[0029] Specifically, Figure 1-Figure 3 As shown, a limit seat 223 is vertically provided on the transverse plate 221, and the limit seat 223 corresponds to the top surface of the lifting plate 210, so that the center of gravity of the limit seat 223 falls on the lifting plate 210, so as to reduce the pressure of the transverse plate 221 extending out of one end of the lifting plate 210, thereby improving the service life of the transverse plate 221, and a guide groove 224 is recessed along the vertical direction of the limit seat 223, and the guide groove 224 faces the other end of the transverse plate 221. A cylinder 225 is provided on the top of the limit seat 223, and the output end of the cylinder 225 passes through one end of the guide groove 224 to connect with the limit assembly 230, so as to adapt to iron chips 1 of different widths.

[0030] Specifically, Figure 2-Figure 3 As shown, the limit assembly 230 includes a moving seat 231, an L-shaped block 232, and a clamping plate 233. The top surface of the moving seat 231 is connected to the output end of the cylinder 225, one end of the moving seat 231 is slidably matched with the guide groove 224, and the other end is connected to the L-shaped block 232. The L-shaped block 232 is inverted, with its vertical portion facing downward, one side of the vertical portion connected to the other end of the moving seat 231, one end of the horizontal portion is vertically arranged at the top of the vertical portion and extends outward, and the upper end of the clamping plate 233 is connected to the other end of the horizontal portion of the L-shaped block 232.

[0031] Specifically, Figure 3-Figure 4As shown, a circular hole is provided at the upper end of the card plate 233, a sleeve 234 is inserted into the circular hole, a screw 235 is inserted into the sleeve 234, one end of the screw 235 is threadedly connected to the horizontal portion of the L-shaped card block 232, and when the screw 235 rotates, the distance between the card plate 233 and the card block 232 is adjusted to meet the requirements of laminated iron core sheets 1 of different thicknesses. The sleeve 234 is rotatably connected to the card plate 233, and connecting rods 236 are respectively provided on both sides of the screw 235, and one end of the connecting rod 236 is inserted into the horizontal portion of the L-shaped card plate 232, and when the screw 235 rotates, the card plate 233 is prevented from rotating.

[0032] Preferably, to prevent the iron core sheet 1 from being scratched, the top surface of the extended end of the transverse plate 221 , the inner side of the L-shaped clamping plate 232 , and the side of the clamping plate 233 facing the L-shaped clamping plate 232 are all covered with flexible rubber pads.

[0033] Specific operation process:

[0034] Move the frame 100 to one side of the core column, start the first motor 123 so that the screw rod 122 adjusts the height of the lifting plate 210, and synchronously start the cylinder 225 to move the L-shaped block 232 to the uppermost end of the guide groove 224, continue to move the frame 100 toward the core column, and start the second motor 212 so that the second motor 212 drives the bidirectional screw rod 213 to rotate, so that the end of the transverse plate 221 extending out of the lifting plate 210 moves to the lower side of the iron core sheet 1 corresponding to the empty space between the two adjacent core columns. Start the first motor 123 again so that the first motor 123 drives the screw rod 122 to rotate, so that the lifting plate 210 drives the transverse plate 221 to move upward, so that the protruding end of the transverse plate 221 abuts against the lower side of the iron core sheet 1, and then start the cylinder 225 to move the L-shaped clamping plate 232 downward, so that the vertical part of the L-shaped clamping plate 232 fits against the inner side of the iron core sheet 1, and the horizontal part abuts against the top of the iron core sheet 1, and then rotate the screw rod 235 to make the clamping plate 233 fit against the outer side of the iron core sheet 1, thereby limiting the position of the iron core sheet 1.

[0035] The first motor 123 is started again, so that the screw rod 122 drives the lifting plate 210 to move upward, so that the core piece 1 moves upward out of the top of the core column, and the core piece 1 is transferred out of the top of the core column to facilitate the installation of high and low voltage coils.
