[0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It realizes power transmission based on the principle of electromagnetic induction, and the transformer coil is an important component for realizing power transmission. When the transformer coil is installed into the transformer box, it needs to be turned over and lifted by a lifting device.

The cushion block 704 is fixedly installed on one side of the rotating block 7011, and the cushion block 704 is also fixedly installed on the bending portion 7032 of the rotating rod 703.

[0075] In order to ensure the normal movement of the gasket on the vertical rod 7010, arc-shaped guide blocks 7012 can also be installed at the bottom of the vertical rod 7010 and on the upper and lower sides of the gasket to ensure the normal rotation of the gasket.

[0076] The setting of the pad 704 facilitates the fixing and clamping of the transformer coil, preventing the rotating rod 703 and the vertical rod 7010 from directly contacting the transformer coil and causing wear on the surface of the transformer coil. The setting of the rotating block 7011 ensures that the contact point between the pad 704 and the transformer coil is always in a tangent position, greatly ensuring the safety of the transformer coil during the hoisting and flipping process.

[0077] As an optimization solution of the present invention, Fig.13 , Fig.14As shown, the limiting member 8 includes a limiting column 803, a pulling rod 802, a handle 801, a sliding block 804, a guide rod 806, a first spring 805 and a fixed seat 807. An adjustment hole 7020 is opened on one side of the strip hole 7022 on the support rod 701. Two fixed seats 807 are arranged one in front and one in the back. The two fixed seats 807 are fixedly installed at the bottom of the support rod 701. The two ends of the guide rod 806 are respectively fixedly installed on the fixed seats 807 arranged one in front and one in the back. The sliding block 804 is slidably installed on the guide rod 806. The first spring 805 is sleeved on the guide rod 806, and the first spring 805 is located between the sliding block 804 and the fixed seat 807. The limiting column 803 is arranged in the adjustment hole 7020, and the limiting column 803 is fixedly installed on the sliding block 804.

[0078] like Fig.10 As shown, a limiting groove 7033 is opened at the end of the horizontal part 7031 on the rotating rod 703, and the limiting column 803 cooperates with the limiting groove 7033. One end of the pulling rod 802 is rotatably installed on the sliding block 804. The handle 801 is set above the support rod 701, and the handle 801 is connected to the other end of the pulling rod 802.

[0079] The setting of the limiter 8 is used to limit the rotating rod 703, ensuring that the rotating rod 703 cooperates with the support rod 701 and the vertical rod 7010 to fix and clamp the transformer coil, ensuring that the staff can adjust the rotating rod 703 as needed to work.

[0080] As an optimization solution of the present invention, Figure 4 As shown, it also includes an auxiliary component 1, which includes a moving plate 102, a guide rod 101, a second spring 104 and a roller 103. The moving plate 102 is symmetrically arranged at both ends of the lifting plate 5, and the moving plate 102 and the lifting plate 5 are slidably matched. The rollers 103 are arranged at both ends of the moving plate 102. The rollers 103 at the ends of the moving plate 102 are arranged one up and one down, and the rollers 103 are rollingly matched with the vertical rod 12. Grooves 501 are opened at both ends of the lifting plate 5. One end of the guide rod 101 is fixedly mounted on the inner wall of the groove 501 at the end of the lifting plate 5, and the other end of the guide rod 101 penetrates the moving plate 102 and extends to the other side of the moving plate 102. The second spring 104 is sleeved on the guide rod 101, and the second spring 104 is located between the inner wall of the groove 501 on the lifting plate 5 and the moving plate 102.

[0081] The setting of the auxiliary component 1 can reduce the friction between the lifting plate 5 and the vertical rod 12. The setting of the guide rod 101 and the movable plate 102 can ensure the normal lifting and lowering of the lifting plate 5 and prevent the lifting plate 5 from tilting during the lifting process, thereby greatly ensuring the normal operation of the lifting plate 5.

[0082] Example 1

[0083] The working process is as follows: push the device to the top of the transformer coil that needs to be flipped, then open the lifting assembly 6 to drive the lifting plate 5 to move downward, the lifting plate 5 moves downward until the support rod 701 is above the transformer coil, the lifting assembly 6 drives the lifting plate 5 to move upward, the lifting plate 5 moves upward to drive the lifting frame 9 to move upward, the lifting frame 9 moves upward to pull the fixed block 7018 to move upward, the fixed block 7018 moves upward, and the rotating rod 703 along the connection between the horizontal part 7031 and the bending part 7032 is driven to rotate until the pad 704 on the bending part 7032 and the pad 704 on the vertical rod 7010 are in contact with the transformer coil, the lifting assembly 6 continues to move upward, which will drive the rotating rod 703 to continue to rotate, and the transformer coil is fixed under the cooperation of the bending part 7032 and the vertical rod 7010, and the lifting assembly 6 continues to rise, which will drive the transformer coil to move upward, thereby achieving the purpose of hoisting the transformer coil;

[0084] When the transformer coil is lifted to a suitable position, the lifting cylinder 4 is turned on to drive the lifting frame 9 to move downward. The downward movement of the lifting frame 9 will drive the clamping member 7 and the transformer coil clamped on the clamping member 7 to move downward. When the transformer coil moves downward to a suitable position, the first motor 301 is turned on to drive the first pulley 303 to rotate. The first pulley 303 drives the second pulley 302 to rotate through the belt 304. The rotation of the second pulley 302 will drive the first threaded rod 308 to rotate. The rotation of the first threaded rod 308 drives the first slider 3010 to slide along the strip through hole 307 on the fixed rod 306. While the first slider 3010 slides, it will drive the top of the push rod 305 to move downward. The bottom of the push rod 305 will push the support rod 701 to rotate around the fixed axis 903. The first motor 301 continues to drive the first threaded rod 308 to rotate, and the first slider 3010 will continue to move downward until the support rod 701 rotates 90° around the fixed axis 903, thereby achieving the purpose of flipping the transformer coil.

[0085] Example 2

[0086] Before hoisting the transformer coil, it is necessary to use a wrench or an electric wrench to rotate the hexagon socket nut 7023. The rotation of the hexagon socket nut 7023 drives the second threaded rod 7019 to rotate. The rotation of the second threaded rod 7019 drives the second slider 7024 to move along the strip hole 7022 on the support rod 701. Since the rotating rod 703 is restricted by the fixed shaft 903, the movement of the second slider 7024 will drive the support rod 701 to move, thereby reducing the distance between the bent portion 7032 of the rotating rod 703 and the vertical rod 7010. Repeating the steps in Example 1 can achieve the purpose of clamping transformer coils of different sizes.

[0087] Example 3

[0088] The difference from Example 1 and Example 2 lies in that a limit member 8 is provided in the present device, and the rotating rod 703 is limited by the limit member 8 before work to ensure that the horizontal portion 7031 of the rotating rod 703 and the support rod 701 are on the same horizontal plane, and the bending portion 7032 is in a slightly tilted state, so as to prevent the transformer coil from being between the vertical rod 7010 and the bending portion 7032 of the rotating rod 703. When the device moves to the top of the transformer coil, the handle 801 is pulled to drive the pulling rod 802 to move, and the movement of the pulling rod 802 drives the sliding block 804 to move along the guide rod 806. The movement of the sliding rod 309 along the guide rod 806 will compress the first spring 805, and at the same time, the limit column 803 is pulled out of the limit slot 7033, so as to achieve the purpose of releasing the limit on the rotating rod 703. In this way, the purpose of hoisting and flipping the transformer coil can be achieved by repeating the above steps.

[0089] Example 4

[0090] When the transformer coil is hoisted and flipped, and the transformer needs to be removed, the second motor 7014 is turned on to drive the worm 7017 to rotate, and the rotation of the worm 7017 drives the worm wheel 7016 to rotate, and the rotation of the worm wheel 7016 drives the third threaded rod 709 to rotate. The rotation of the third threaded rod 709 will drive the third slider 7025 to move along the slide groove 708 toward a position away from the middle of the cross bar 707. The movement of the third slider 7025 will drive the vertical rod 7010 to move. The distance between the vertical rods 7010 on both sides of the center line of the cross bar 707 becomes larger and larger, which will cause the turned-over transformer coil to fall off from the gap between the vertical rods 7010, thereby achieving the purpose of unloading the turned-over transformer.
