[0019] 1. When the present invention is in use, the correction mechanism can prevent the stacked silicon steel sheets from shifting when the core is compressed, avoid additional correction processes, and reduce the noise and loss of the core; the hydraulic cylinder drives the connecting bent rod to move the piston, squeeze the liquid in the fixed tank into the oil storage tank, and then enter the fixed cylinder through the connecting pipe, push the limit column, movable rod and correction plate to move, squeeze the core to make it stacked neatly, if some correction plates contact the core first, other correction plates will continue to move until they are all in contact, and finally gather the core.

[0021] 3. The four corners of the stabilizing frame outside the fixed cylinder are connected to the four corners of the fixed frame, which enhances the stability of the entire correction mechanism and ensures the reliability of the correction process. Tension springs 1 and 2 play a role in the related operations of the movable plug rod and the bending column, respectively, to reset the various components of the device and ensure the normal operation of the device. The torsion spring can reset the rotating box, so that the hook can better fix the clamping plate, further improving the reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] After the interior of the fixed cylinder 303 is filled with liquid, the limiting column 304 and the movable rod 305 can be pushed to move. When the liquid in the fixed cylinder 303 is extracted, the limiting column 304 and the movable rod 305 can be retracted under the action of hydraulic pressure. The end of the movable rod 305 away from the limiting column 304 is fixedly connected to the correction plate 307, and the movable rod 305 can drive the correction plate 307 to move, and then the stacked iron cores can be pushed into alignment to achieve the role of auxiliary correction. Two movable columns 312 are slidably connected to the top of the fixed frame 302, and the end of the movable column 312 away from the fixed frame 302 is fixedly connected to the slider 306. Two slide grooves 308 are provided inside the correction plate 307 close to the fixed frame 302. The slider 306 is slidably connected to the inside of the slide groove 308. The slider 306 slides inside the slide groove 308 to realize the removal and installation of the correction plate 307.

[0040] One end of the fixed cylinder 303 away from the correction plate 307 is fixedly connected with a connecting pipe, and the connecting pipe can pass liquid. One end of the four connecting pipes is respectively fixedly connected to the four sides of the oil storage tank 309.

[0041] In the specific setting, when the iron core of the energy storage transformer is compressed, the hydraulic cylinder 2 is started, and the output end of the hydraulic cylinder 2 moves downward to drive the connecting crankshaft to move downward, thereby driving the piston to move downward, and then the liquid inside the fixed tank 301 can be squeezed out of the fixed tank 301 and enter the oil storage tank 309 through the oil pipe. Since the oil storage tank 309 is full of liquid, the liquid will enter the fixed cylinder 303 through the connecting pipe, and push the limit column 304 and the movable rod 305 to move toward the middle of the mounting frame 1, and then it can The correction plates 307 are driven to move toward the middle, and the stacked iron cores are squeezed by the correction plates 307, so that the stacked iron cores are neatly stacked. If two of the correction plates 307 touch the iron cores first, the two correction plates 307 will not move any further due to the obstruction of the iron cores, and the other two correction plates 307 will continue to move toward the middle because they do not touch the iron cores, and until they touch the iron cores. When all four correction plates 307 touch the iron cores, they will tightly gather the iron cores toward the middle, and when the correction plates 307 can no longer move toward the middle;

[0042] If the output end of the hydraulic cylinder 2 needs to move downward, the excess liquid in the fixed tank 301 will continue to move toward the inside of the oil storage tank 309. The hydraulic pressure generated by the excess liquid will move the movable plug rod 311 downward and overcome the tension of the tension spring 1, so it will not affect the compression of the energy storage transformer core.

[0043] The replacement mechanism includes a clamping plate 401, which can clamp the iron core. Both ends of the top of the clamping plate 401 are fixedly connected to fixed rods 402. The top bottom of the mounting frame 1 is fixedly connected to two fixed forks 403. The bottom of the fixed fork 403 is fixedly connected to a fixed pin 404. The fixed pin 404 can provide an installation position. The external rotation of the fixed pin 404 is connected to a rotating box 411. The rotating box 411 can provide an installation position and can rotate around the fixed pin 404. The bottom of the rotating box 411 is fixedly connected to a card Hook 405, the hook 405 can hook the fixing rod 402, so that the pressing plate 401 can be temporarily placed on the top of the mounting frame 1, the outer sleeve of the fixing pin 404 is provided with a torsion spring, and the torsion spring can reset the rotating box 411, the outer part of the fixing rod 402 is engaged with the inner side of the hook 405, and the bottom of the output end of the hydraulic cylinder 2 is fixedly connected with a hexagonal head 409, which can be engaged with the groove on the top of the pressing plate 401, and then the pressing plate 401 can be easily installed, and the inner part of the hexagonal head 409 is provided with a socket 410;

[0044] The top and bottom of the clamping plate 401 are fixedly connected with a fixed outer cylinder 406, and the interior of the fixed outer cylinder 406 is slidably connected with a bent column 407. The top of the bent column 407 is fixedly connected with a latch 408, and the latch 408 can be inserted into the interior of the socket 410 to complete the installation of the clamping plate 401. The latch 408 is slidably connected to the top of the clamping plate 401, and the bottom of the bent column 407 is fixedly connected with a limiting ring. The limiting ring is slidably connected to the interior of the fixed outer cylinder 406, and the latch 408 is engaged with the socket 410. A tension spring 2 is fixedly connected between the interior of the bent column 407 and the interior of the fixed outer cylinder 406, one end of the torsion spring is fixedly connected to the exterior of the fixed pin 404, and the other end of the torsion spring is fixedly connected to the interior of the rotating box 411;

[0045] When replacing the clamping plate 401, first start the hydraulic cylinder 2, and the output end of the hydraulic cylinder 2 is retracted, so that the clamping plate 401 can be driven to move upward, and the fixed rod 402 on the clamping plate 401 can be driven to move upward. When the fixed rod 402 moves to the bottom of the hook 405, the hook 405 can be rotated to the side away from the clamping plate 401 under the pressure of the fixed rod 402, and then the hook 405 can be used to drive the rotating box 411 to rotate, and the rotating box 411 is rotated to compress the torsion spring. When the fixed rod 402 moves to the bottom of the hook 405, the hook 405 can be rotated to the side away from the clamping plate 401. After 02 moves to the inner side of the hook 405, the rotating box 411 can be driven to rotate under the action of the torsion spring, and then the hook 405 can be driven to rotate, so that the hook 405 can be engaged with the fixing rod 402, and then the fixing rod 402 can be hooked by the hook 405, and then the pressing plate 401 can be kept under the top of the mounting frame 1. At this time, the bent column 407 is pulled outward, so that the bent column 407 drives the latch 408 to move outward, and then the latch 408 can be pulled out of the inside of the insertion hole 410;

[0046] At this time, the hydraulic cylinder 2 can be started again, so that the output end of the hydraulic cylinder 2 moves out of the top groove of the clamping plate 401. At this time, the clamping plate 401 is pulled outward, and then the fixing rod 402 can be slid out of the inner side of the hook 405, and the removal of the clamping plate 401 is completed. When installing, align the fixing rod 402 with the inner side of the hook 405, and slide the fixing rod 402 into the inner side of the hook 405. At this time, the hydraulic cylinder 2 is started, so that the output end of the hydraulic cylinder 2 moves downward, and the bending column 407 is pushed outward. The hexagonal head 409 can be pulled out from the side, and then the hexagonal head 409 can be inserted into the groove inside the top of the clamping plate 401. At this time, the bent column 407 is loosened, and the tension of the tension spring 2 can drive the bent column 407 to return to its original position, and then the latch 408 can be driven to return to its original position, so that the latch 408 is inserted into the inside of the socket 410. At this time, the hook 405 is rotated outward, and the hydraulic cylinder 2 is started again so that the output end of the hydraulic cylinder 2 drives the clamping plate 401 to move downward, and the installation of the clamping plate 401 is completed.

[0047] Working principle: when the iron core of the energy storage transformer is compressed, the hydraulic cylinder 2 is started, and the output end of the hydraulic cylinder 2 moves downward to drive the connecting bent rod to move downward, thereby driving the piston to move downward, and then the liquid inside the fixed tank 301 can be squeezed out of the fixed tank 301, and enter the oil storage tank 309 through the oil pipe. Since the oil storage tank 309 is full of liquid, the liquid will enter the fixed cylinder 303 through the connecting pipe, and push the limit column 304 and the movable rod 305 to move toward the middle of the mounting frame 1, and then it can drive the correction plate 307 to move toward the middle, and use the correction plate 307 to squeeze the stacked iron cores, so that the stacked iron cores are neatly stacked;

[0048] If two of the correction plates 307 touch the iron core first, then these two correction plates 307 will not move any further due to the obstruction of the iron core, while the other two correction plates 307, since they do not touch the iron core, will continue to move toward the middle until they touch the iron core. When all four correction plates 307 touch the iron core and tightly gather the iron core toward the middle, and when the correction plates 307 can no longer move toward the middle, if the output end of the hydraulic cylinder 2 still needs to move downward, the excess liquid in the fixed tank 301 will continue to move toward the inside of the oil storage tank 309. At this time, the hydraulic pressure generated by the excess liquid will move the movable plug rod 311 downward and overcome the tension of the tension spring 1, so it will not affect the compression of the iron core of the energy storage transformer.

[0049] When replacing the clamping plate 401, first start the hydraulic cylinder 2, and the output end of the hydraulic cylinder 2 is retracted, so that the clamping plate 401 can be driven to move upward, and the fixed rod 402 on the clamping plate 401 can be driven to move upward. When the fixed rod 402 moves to the bottom of the hook 405, with the squeezing of the fixed rod 402, the hook 405 can be rotated to the side away from the clamping plate 401, and then the hook 405 can be used to drive the rotating box 411 to rotate, and the rotation of the rotating box 411 is used to compress the torsion spring. When the fixed rod 402 moves to the inner side of the hook 405, the rotating box 411 can be driven to rotate under the action of the torsion spring, and then the hook 405 can be driven to rotate. 05 rotates, so that the hook 405 can be engaged with the fixing rod 402, and then the fixing rod 402 can be hooked by the hook 405, and then the clamping plate 401 can be kept under the top of the mounting frame 1, and at this time, the bent column 407 is pulled outward, so that the bent column 407 drives the latch 408 to move outward, and then the latch 408 can be pulled out of the inside of the socket 410, and at this time, the hydraulic cylinder 2 can be started again, so that the output end of the hydraulic cylinder 2 moves out of the top groove of the clamping plate 401, and at this time, the clamping plate 401 is pulled outward, and then the fixing rod 402 can slide out of the inner side of the hook 405, and the removal of the clamping plate 401 is completed;

[0050] During installation, align the fixing rod 402 with the inner side of the hook 405 and slide the fixing rod 402 into the inner side of the hook 405. At this time, start the hydraulic cylinder 2, so that the output end of the hydraulic cylinder 2 moves downward, and at the same time, pull the bent column 407 outward, and then the hexagonal head 409 can be inserted into the groove inside the top of the clamping plate 401. At this time, release the bent column 407, and under the tension of the tension spring 2, the bent column 407 can be driven to return to its original position, and then the latch 408 can be driven to return to its original position, so that the latch 408 is inserted into the inside of the socket 410. At this time, rotate the hook 405 outward, and start the hydraulic cylinder 2 again so that the output end of the hydraulic cylinder 2 drives the clamping plate 401 to move downward, completing the installation of the clamping plate 401.
