Description

Technical Field

[0001] This invention relates to the field of transformer positioning device technology, specifically a transformer body positioning device. Background Technology

[0002] When transporting a transformer, the transformer components need to be placed in the enclosure for fixation. The weight of the transformer core varies. The heavier core will exert greater pressure on the enclosure due to acceleration during transportation. The pressure changes over a long period of time can easily cause the enclosure to deform and be damaged, and it can also damage the core. At the same time, the long-term acceleration changes can also cause the coils wound on the core to loosen, which will lead to a decrease in stability when energized and make it prone to vibration and overheating.

[0003] The existing transformer positioning devices have the following drawbacks:

[0004] The prior art CN116461835A discloses a transformer body fixing device for transportation. This technology includes a device body with a base at its bottom end. A magnetic block is fixedly installed inside the bottom end of the base. When the device body is inserted into the top end of a plug rod, the connecting block at the bottom end of the device body moves upward under the pushing force of the plug rod, thereby causing a limiting plate to move towards the outer wall of the plug rod. The limiting plates in four directions fix the sides of the plug rod. Simultaneously, an inflated air spring pushes a fixing block towards the plug rod, thus fixing the top end of the plug rod. This achieves a stable connection between the plug rod and the device body. After fixing the device body, energizing an electromagnet ensures a stable connection between the bottom end of the plug rod and the base, preventing the internal windings from loosening due to shaking during transportation and affecting subsequent use.

[0005] The aforementioned technology fixes the bottom of the transformer, but does not protect the transformer body itself. When a casing is used to protect the body, the casing and the body are prone to shaking and collisions. When the object being fixed is the transformer core, damage to the core will cause a decrease in core quality, and loosening of the coils on the core will also cause a decrease in the overall quality of the transformer core. Therefore, a transformer body positioning device is needed to solve this problem, which can protect the transformer core, prevent collisions between the core and the protective casing, ensure stable core fixing, prevent deformation of the protective casing, and prevent loosening of the coils.

A positioning bowl is installed at one end of the mounting rod, the positioning bowl is located outside the positioning pin, and a polyurethane insulating pad is installed on the inner wall of the positioning bowl.

[0012] Preferably, the positioning mechanism further includes a spring, bolts, a compression plate, and a rubber pad. A spring is installed on the inner wall of the guide frame, and one end of the spring is connected to one side of the positioning plate. Multiple bolts are installed through the top of the guide frame, and one end of each bolt penetrates the top of the positioning plate.

A bolt is installed through one side of each right-angled block. Multiple blocks are symmetrically installed on the outer side of the rectangular ring. A threaded rod is installed through the top of each block, and one end of the threaded rod penetrates the bottom of the block. A support plate is installed at one end of the threaded rod.

[0014] Preferably, a storage block is symmetrically installed on the outer side of the rectangular ring, and guide grooves are symmetrically opened on both sides of the storage block. A positioning rod is movably installed on the inner side of the guide groove, and one end of the positioning rod passes through one side of the threaded rod. A spring is installed on one end of the positioning rod, and one end of the spring is connected to the inner wall of one side of the guide groove.

[0015] Preferably, threaded rods are symmetrically installed through both sides of the box, a closing plate is installed at one end of the threaded rods, and a sealing gasket is installed on one side of the closing plate.

[0016] Preferably, the transformer body positioning device is used as follows:

[0017] S1. Place the iron core body into the box, the second positioning nail enters the second positioning bowl and is supported, then cover the top of the box and make the first positioning bowl press against the outside of the first positioning nail to fix the first positioning nail, thereby fixing the iron core body.

[0018] S2. Then bolt two rotates and passes through the top of positioning pin one to fix positioning bowl one and positioning pin one in place;

[0019] S3. Then the positioning plate extends to contact the web plate to position and fix the web plate. Next, the closing plate is rotated to close the gaps on both sides of the box, while the pressing plate presses and fixes the coil wound on the iron core body.

[0020] Preferably, step S3 further includes the following steps:

[0021] S31. Rotate the support plate to make it perpendicular to the box body. Then extend the positioning rod outward and insert it into the hole on the threaded rod to fix the threaded rod, thereby fixing the support plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, the iron core body is placed in the housing, the second positioning pin is inserted into the second positioning bowl and supported, then the cover plate is placed on the top of the housing and the first positioning bowl is pressed against the outside of the first positioning pin to fix the first positioning pin, thereby fixing the iron core body. Subsequently, the second bolt rotates and passes through the top of the first positioning pin to fix the first positioning bowl and the first positioning pin together, thereby positioning and fixing the iron core body and avoiding the situation where the positioning component directly contacts the iron core body, which would easily damage the iron core body.

[0024] 2. In this invention, after the positioning pin and the positioning bowl pair position the iron core body, the positioning plate extends out to contact the web plate and fix the web plate. Then, the bolt three rotates and is inserted into the hole on the positioning plate to fix the positioning plate. This can further increase the stability of the iron core body and avoid the situation where the iron core body exerts excessive pressure on the positioning pin and the positioning bowl pair due to acceleration, causing the positioning pin to bend.

[0025] 3. This invention rotates the support plate to make it perpendicular to the box body, then extends the positioning rod outward and inserts it into the hole on the threaded rod to fix the threaded rod, thereby fixing the support plate. This provides support for the side wall of the box body when it is subjected to compressive force, preventing the box body from being deformed and damaged due to irregular pressure over a long period of time.

[0026] 4. The present invention uses an extrusion plate to press and fix the coil wound on the iron core body, making the coil wound on the iron core body more stable and preventing the coil from loosening and falling off the iron core body due to impact and shaking during transportation.

Multiple insulating plates 7 are symmetrically installed on both sides of the core body 6. Web plates 8 are symmetrically installed on both sides of the insulating plates 7. Multiple positioning devices are installed on the top of the upper web plate 8. The bottom of the cover plate 4 is equipped with multiple mounting rods 10. A positioning bowl 11 is mounted on one end of each mounting rod 10, and the positioning bowl 11 is located outside the positioning nail 9. A polyurethane insulating gasket 12 is installed on the inner wall of the positioning bowl 11. A flange cover 13 is movably mounted on the outer side of the mounting rod 10. Bolts 14 are symmetrically installed through the top of the flange cover 13, and one end of each bolt 14 penetrates the top of the positioning nail 9. Multiple positioning nails 15 are installed at the bottom of the lower web plate 8. The bottom inner wall of the box body 1... Multiple mounting rods 16 are installed, with a positioning cup 17 installed at one end of each rod. The positioning cup 17 is located outside the positioning pin 15. A polyurethane insulating pad 18 is installed on the inner wall of the positioning cup 17. The housing 1 provides storage space for the iron core body 6. When the iron core body 6 is placed into the housing 1, the positioning pin 15 is first inserted into the positioning cup 17. Then, the cover plate 4 is placed on top of the housing 1, and the positioning cup 11 covers the outside of the positioning pin 9 to position the positioning pin 9, thereby positioning the iron core body. The body 6 is positioned, and then the cover plate 4 is fixed above the connecting plate 3 by bolt 5, thereby sealing the top of the box body 1. Then, bolt 14 is screwed into the top of the positioning nail 9, thereby fixing the positioning bowl 11 and the positioning nail 9 together to ensure the stability of the iron core body 6. The polyurethane insulation pad 12 can prevent the positioning bowl 11 and the positioning nail 9 from contacting each other and causing damage. The polyurethane insulation pad 18 can prevent the positioning bowl 17 and the positioning nail 15 from contacting each other and causing damage.

[0042] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of the present invention is a transformer body positioning device;

[0043] The system includes a positioning mechanism. A positioning mechanism is symmetrically arranged on the inner wall of the housing 1. The positioning mechanism includes a guide frame 19 and a positioning plate 20. The guide frame 19 is symmetrically installed on the inner wall of the housing 1. The positioning plate 20 is movably installed on the inner side of the guide frame 19, and one side of the positioning plate 20 extends out of the guide frame 19 and contacts the web plate 8. The positioning mechanism also includes a spring 21, bolts 22, a pressing plate 36, and a rubber pad 37. A spring 21 is installed on the inner wall of the guide frame 19, and one end of the spring 21 is connected to one side of the positioning plate 20. Multiple bolts 22 are installed through the top of the guide frame 19, and one end of each bolt 22 penetrates the top of the positioning plate 20. The pressing plate 36 is installed at the bottom of the positioning plate 20, and a rubber pad 37 is installed on one side of the pressing plate 36. The iron core body 6 is... When positioned inside the housing 1, spring 21 compresses the positioning plate 20, causing it to move towards and contact the web plate 8. Then, bolt 22 rotates downward and inserts into the hole at the top of the positioning plate 20 to position it. This allows the positioning plate 20 to further position and reinforce the web plate 8, preventing components such as the positioning nail 9 from bending and being damaged. At the same time, the compression plate 36 compresses and fixes the coil wound on the iron core body 6, making the coil wound more stable on the iron core body 6. This prevents the coil from loosening and falling off the iron core body 6 due to impacts or shaking during transportation. The rubber pad 37 is made of soft rubber, which can fully contact the outer coil on the iron core body 6 when compressing the coil, thereby increasing the fixing effect on the coil.

[0044] Please see Figure 1 , Figure 7 and Figure 8 One embodiment of the present invention is a transformer body positioning device;

[0045] The enclosure includes a rectangular ring 23 and a storage block 29. The rectangular ring 23 is movably mounted on the outer side of the enclosure 1. Multiple right-angled blocks 24 are symmetrically mounted on the outer side of the enclosure 1. A bolt 25 is threaded through one side of each right-angled block 24. Multiple blocks 26 are symmetrically mounted on the outer side of the rectangular ring 23. A threaded rod 27 is threaded through the top of each block 26, with one end of the threaded rod 27 penetrating the bottom of the block 26. A support plate 28 is mounted on one end of the threaded rod 27. Storage blocks 29 are symmetrically mounted on the outer side of the rectangular ring 23. Guide grooves 30 are symmetrically opened on both sides of each storage block 29. A positioning rod 31 is movably mounted on the inner side of the guide groove 30, with one end of the positioning rod 31 penetrating one side of the threaded rod 27. A spring 32 is mounted on one end of the positioning rod 31. One end is connected to the inner wall of the guide groove 30. The rectangular ring 23 is fitted onto the outside of the housing 1. Then, the bolt 25 is rotated to press and fix the rectangular ring 23, ensuring the stability of the rectangular ring 23 on the outside of the housing 1. Then, the support plate 28 is rotated to make the support plate 28 perpendicular to the housing 1. Next, the spring 32 presses the positioning rod 31, causing the positioning rod 31 to move and extend into the hole of the threaded rod 27, thereby fixing the threaded rod 27 and then fixing the support plate 28. This allows the support plate 28 to provide support for the side wall of the housing 1, avoiding deformation and damage to the housing 1 caused by the pressure on the positioning plate 20 generated by the acceleration of the transformer core body 6 during the transportation of the housing 1, and improving the service life of the housing 1.

[0046] Please see Figure 1 One embodiment of the present invention is a transformer body positioning device;

A sealing plate 34 is installed at one end of the threaded rod 33, and a sealing gasket 35 is installed on one side of the sealing plate 34. After the iron core body 6 is fixed in the housing 1, bolts 14 and 22 can be easily operated through the notch 2. After the operation is completed, the notch 2 is closed by rotating the sealing plate 34, and then the sealing gasket 35 seals the gap between the sealing plate 34 and the housing 1, thereby preventing external moisture from entering the housing 1 and causing the iron core body 6 to rust.

[0048] The method of using the transformer body positioning device is as follows:

[0049] S1. Place the iron core body 6 into the box 1. Positioning pin 2 15 enters the positioning bowl 2 17 and is supported. Then cover the top of the box 1 with the cover plate 4 and press the positioning bowl 11 on the outside of the positioning pin 9 to fix the positioning pin 9, thereby fixing the iron core body 6.

[0050] S2. Then bolt 14 rotates and passes through the top of positioning pin 9 to fix and connect positioning bowl 11 and positioning pin 9.

[0051] S3. Then, the positioning plate 20 extends to contact the web plate 8 to position and fix the web plate 8. Then, the closing plate 34 is rotated to close the gaps 2 on both sides of the box body 1. At the same time, the pressing plate 36 presses and fixes the coil wound on the iron core body 6.

[0052] S3 also includes the following steps:

[0053] S31. Rotate the support plate 28 so that the support plate 28 is perpendicular to the box 1. Then extend the positioning rod 31 outward and insert it into the hole on the threaded rod 27 to fix the threaded rod 27, and then fix the support plate 28.

[0054] Working principle: Before using the transformer core positioning device, check whether there are any problems affecting its use. Place the core body 6 into the housing 1. Positioning pin 2 15 is supported by positioning bowl 2 17. Then, cover plate 4 is placed on top of housing 1, and positioning bowl 1 11 is pressed against the outside of positioning pin 1 9 to fix positioning pin 1 9, thereby fixing the core body 6. Then, bolt 2 14 is rotated and passes through the top of positioning pin 1 9 to fix positioning bowl 1 11 and positioning pin 1 9. Then, positioning plate 20 extends out to contact web plate 8 to position and fix web plate 8. The extrusion plate 36 extrudes and fixes the coil wound on the iron core body 6, making the coil wound on the iron core body 6 more stable and preventing the coil from loosening and falling off the iron core body 6 due to impact or shaking during transportation. Then, the sealing plate 34 is rotated to close the gaps 2 on both sides of the box 1. At the same time, the extrusion plate 36 extrudes and fixes the coil wound on the iron core body 6. The support plate 28 is rotated to make the support plate 28 perpendicular to the box 1. Then, the positioning rod 31 extends outward and is inserted into the hole on the threaded rod 27 to fix the threaded rod 27, thereby fixing the support plate 28.
