Description

Technical Field

[0001] This invention belongs to the field of iron core transportation technology, and in particular relates to a support device for preventing transformer iron core displacement and deformation. Background Technology

[0002] In the power industry, transformer cores are an important component of transformers. Transformer cores come in a variety of types and shapes, each with its unique advantages and applicable scenarios. For example, toroidal cores are usually toroidal or nearly toroidal, so special care must be taken during transportation and storage to prevent them from shifting or deforming. Therefore, it is necessary to fix and limit the cores and take corresponding protective measures before transportation.

[0003] Traditional methods of securing iron cores typically involve stacking them on a support plate, wrapping them with plastic film for protection and fixation, and then using fasteners such as clamps or brackets, along with bolts or other connectors, to enclose and limit the iron cores. This method ensures that the iron cores do not shift during transportation. However, when unloading iron cores wrapped with plastic film, the fasteners must be removed first, followed by the plastic film, which takes a considerable amount of time and makes the unloading process cumbersome, reducing unloading efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a support device to prevent transformer core displacement and deformation, which facilitates unloading and improves efficiency.

[0005] To achieve the above objectives, the invention employs the following technical solution: a support device for preventing transformer core displacement and deformation, comprising a support base plate, wherein four hinged rotatable side plates are provided on the top of the support base plate, a limiting plate is provided on the top of the rotatable side plates, a second permanent magnet is embedded in the bottom of the limiting plate, a locking frame that can slide up and down is provided on the outer periphery of the four rotatable side plates, a second electromagnet that can magnetically attract the second permanent magnet is embedded in the top of the locking frame, magnetic attraction components are provided on both sides of the rotatable side plates, multiple limiting components are provided on the top of the support base plate, and an air-filled cavity communicating with the limiting components is provided inside the support base plate.

[0006] By adopting the above technical solution, and by designing a supporting base plate and four hinged rotatable side plates, as well as limiting plates and locking frames, the four rotatable side plates can be unfolded to form a platform when loading and unloading the iron core, thereby facilitating unloading personnel to load and unload the internal iron core and improving efficiency. Utilizing the magnetic attraction of permanent magnets and electromagnets, it is easy to quickly lock and unlock the rotatable side plates, improving the flexibility of the supporting device. When the four rotatable side plates are closed together, they will surround the iron core inside, providing initial protection and limiting effect. At the same time, the limiting components provide internal support for the iron core stacked on the limiting posts, further preventing the iron core from easily shifting and deforming during transportation.

[0007] Optionally, the top of the supporting base plate is provided with an embedding groove adapted to the lock frame, the two sides of the lock frame are provided with lifting blocks, and the top of the supporting base plate is provided with grooves located on both sides of the top of the embedding groove, and the lifting blocks are adapted to the grooves.

[0008] By adopting the above technical solution, by opening an embedding groove and a recess on the supporting base plate to match the lock frame and its lifting block, the unlocked lock frame can slide into the embedding groove and be stored inside. At the same time, it is convenient for users to lift the lock frame out of the embedding groove by lifting the block to lock the flip-up side panel, which improves the convenience and stability of use.

[0009] Optionally, the lock frame has through grooves on both sides of its four inner walls, and the size of the through grooves is larger than the size of the hinge connecting the flip-up side plate and the supporting base plate.

[0010] By adopting the above technical solution, through grooves are set on both sides of the inner wall of the four sides of the lock frame, so that the lock frame can smoothly bypass the connecting hinge between the flip-up side plate and the supporting base plate during the sliding process, avoiding structural interference and improving the sliding flexibility and reliability of the lock frame.

[0011] Optionally, the magnetic attraction component includes a first electromagnet and a first permanent magnet disposed on both sides of the rotatable side plate, wherein the first electromagnet on one side of the rotatable side plate is magnetically attracted to the first permanent magnet on the adjacent side of the rotatable side plate.

[0012] By adopting the above technical solution, and by setting the first electromagnet and the first permanent magnet on both sides of the rotatable side plate, magnetic attraction connection between adjacent rotatable side plates is realized, which enhances the structural stability and overall rigidity of the support device. At the same time, a single rotatable side plate can be lowered according to actual needs, which improves the flexibility of use.

[0013] Optionally, the bottom of the supporting base plate is provided with three lifting plates, the three lifting plates are spaced at the same distance, and the width of the limiting plate is the same as the total height of the supporting base plate and the lifting plates.

[0014] By adopting the above technical solution, the gap formed between the lifting plates makes it convenient for the forks of the forklift to insert into the gap to move the supporting device. The width of the limiting plate is the same as the total height of the supporting base plate and the lifting plate, so that after the flip-up side plate is unfolded, the limiting plate can be supported on the ground.

[0015] Optionally, the side wall of the supporting base plate is provided with an inflation tube that extends into the inflation cavity at one end, and a valve is provided at the end of the inflation tube located outside the supporting base plate.

[0016] By adopting the above technical solution, the inflation tube can be connected to the air pump, which facilitates inflation or deflation of the inflation cavity. When inflating, the air pressure can push the limiting plate on the outside of the limiting post to abut against the inner wall of the iron core, thereby achieving the effect of internal support and limiting.

[0017] Optionally, the limiting member includes a limiting post disposed on the top of the supporting base plate, the bottom of the limiting post having a connecting pipe extending into the interior of the inflation cavity, and the interior of the limiting post having a ventilation cavity communicating with the connecting pipe.

[0018] By setting up structures such as limiting posts, connecting pipes, and ventilation chambers, the connection between the inflation chamber and the limiting component is realized, allowing the gas in the inflation chamber to be transferred to the inside of the limiting post, thereby achieving the effect of pushing the limiting plate.

[0019] Optionally, the sidewall of the limiting post is provided with three telescopic members at equal intervals. Each telescopic member includes an embedded housing embedded inside the limiting post. A piston plate is slidably connected inside the embedded housing. A piston rod is provided on the sidewall of the piston plate. One end of the piston rod extends through the embedded housing to the outside and connects to a limiting stop plate.

[0020] By adopting the above technical solution, and by setting telescopic components and limiting plates on the side wall of the limiting post, the limiting post can be adapted and adjusted according to the shape and size of the annular iron core, thereby improving the fit and stability of the internal support.

[0021] Optionally, the embedded housing has an air hole on the side near the ventilation cavity, and the limiting plate is an arc-shaped plate. The limiting plate of the arc-shaped plate can better adapt to the curved shape of the annular iron core.

[0022] Optionally, the top of the lock frame is provided with an embedded master control button, and the side wall of the flip-up side panel is provided with an embedded individual control button.

[0023] By adopting the above technical solution, the master control button can simultaneously open and close the four second electromagnets on the lock frame, while the single control button is used to control the opening and closing of the first electromagnet on the corresponding single flip-up side plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. By designing a supporting base plate and four hinged rotatable side plates, as well as limiting plates and locking frames, the four rotatable side plates can be unfolded to form a platform when loading and unloading the iron core, thereby facilitating unloading personnel to load and unload the internal iron core, improving efficiency. Utilizing the magnetic attraction of permanent magnets and electromagnets, the rotatable side plates can be quickly locked and unlocked, improving the flexibility of the supporting device; 2. When the four rotatable side plates are closed together, they will surround the iron core inside, providing initial protection and limiting effect. At the same time, the limiting components provide internal support for the iron core stacked on the limiting posts, further preventing the iron core from slipping during transportation. 3. The inflation tube can be connected to an air pump, which facilitates inflation or deflation of the inflation chamber. When inflated, the air pressure can push the limiting plate on the outside of the limiting post against the inner wall of the iron core, so that the limiting post can be adjusted according to the size of the annular iron core, improving the fit and stability of the inner support; 4. The generation and disappearance of the magnetic field of the second electromagnet are controlled by controlling the current on the lock frame through the main control button, which facilitates one-key locking and unlocking. The single control button is used to control the opening and closing of the first electromagnet on the corresponding single flip-up side plate, which facilitates unfolding a single flip-up side plate or fully unfolding it according to actual needs, improving flexibility.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] like Figure 1 As shown in Figure 3, the specific solution of the embodiment is as follows: A support device for preventing transformer core displacement and deformation includes a support base plate 1. Each of the four sides of the top of the support base plate 1 is hinged with a rotatable side plate 4. A limit plate 5 is provided at the top of the rotatable side plate 4. A second permanent magnet 501 is embedded at the bottom of the limit plate 5. A locking frame 6 that can slide up and down is provided on the side wall of the rotatable side plate 4. A second electromagnet 601 that can magnetically attract the second permanent magnet 501 is embedded at the top of the locking frame 6. Magnetic attracting components are provided on both sides of the rotatable side plate 4. The magnetic attracting components include... The first electromagnet 401 and the first permanent magnet 402 are installed on both sides of the rotatable side plate 4. The first electromagnet 401 on one side of the rotatable side plate 4 is magnetically attracted to the first permanent magnet 402 on the side of the adjacent rotatable side plate 4. By setting the first electromagnet 401 and the first permanent magnet 402 on both sides of the rotatable side plate 4, the magnetic connection between the adjacent rotatable side plates 4 is realized, which enhances the structural stability and overall rigidity of the support device. At the same time, the rotatable side plate 4 on one side can be lowered according to actual needs, which improves the flexibility of use.

[0037] It is important to note that, as is well known, both electromagnets and permanent magnets are types of magnets and possess north and south magnetic poles. Two magnets attract each other with opposite poles and repel each other with like poles. In this embodiment, the magnetic field generated by the first electromagnet 401 after it is energized is in the same direction as the magnetic field of the side of the adjacent first permanent magnet 402 facing the first electromagnet 401. Therefore, after the first electromagnet 401 is energized, it will generate a repulsive force with the adjacent first electromagnet 401.

[0038] Specifically, such as Figure 2 As shown, the magnetic field generated by the first electromagnet 401 after being energized has the direction of the magnetic field facing the first permanent magnet 402 as the south pole, and the magnetic field of the contact surface between the first permanent magnet 402 and the first electromagnet 401 is also the south pole.

[0039] When the first electromagnet 401 is not energized, it has no attraction. However, due to its iron content, when the rotatable side plate 4 is upright and the other rotatable side plates 4 are together, the first permanent magnet 402, which is in contact with the first electromagnet 401, attracts the first electromagnet 401, thus stabilizing the two rotatable side plates together. When it is necessary to open one of the rotatable side plates 4, the first electromagnet 401 on that rotatable side plate 4 is energized, causing the first electromagnet 401 to generate an electromagnetic field. Since this electromagnetic field and the magnetic field of the adjacent first permanent magnet 402 are the same polarity magnetic field, the first electromagnet 401 and the first permanent magnet 402 change from an attractive state to a repulsive state, thus opening the rotatable side plate 4.

[0040] Similarly, the second permanent magnet 501 and the second electromagnet 601 are also like this. When not energized, the second permanent magnet 501 will attract the second electromagnet 601, thereby fixing the lock frame 6 to the bottom of the limiting plate 5. Once energized, the second electromagnet 601 will generate a magnetic field with the same polarity that repels the second permanent magnet 501, eliminating the attraction effect. At this time, the lock frame will automatically detach from the limiting plate 5.

[0041] Preferably, the top of the supporting base plate 1 is provided with multiple limiting members 7, the interior of the supporting base plate 1 is provided with an inflatable cavity 103 communicating with the limiting members 7, the bottom of the supporting base plate 1 is provided with three lifting plates 2, the spacing between the three lifting plates 2 is the same, the width of the limiting plate 5 is the same as the total height of the supporting base plate 1 and the lifting plates 2, and the side wall of the lifting plate 2 is provided with a power supply 3, so that the internal battery can be charged by plugging in the charging cable, and the electromagnet can be energized by the battery.

[0042] The gap between the lifting plates 2 allows the forks of the forklift to be inserted into the gap to move the support device. The width of the limiting plate 5 is the same as the total height of the supporting base plate 1 and the lifting plate 2, so that after the flip-up side plate 4 is unfolded, the limiting plate 5 can be supported on the ground.

[0043] By designing a supporting base plate 1 and four hinged rotatable side plates 4, as well as a limiting plate 5 and a locking frame 6, the four rotatable side plates 4 can be unfolded to form a platform when loading and unloading the iron core, thereby facilitating the loading and unloading of the iron core by unloading personnel and improving efficiency. The magnetic attraction of permanent magnets and electromagnets makes it easy to quickly lock and unlock the rotatable side plates 4, improving the flexibility of the supporting device. When the four rotatable side plates 4 are closed together, they will surround the iron core inside, providing initial protection and limiting effect. At the same time, the limiting component 7 provides internal support for the iron core stacked on the limiting post 71, further preventing the iron core from easily shifting and deforming during transportation.

[0044] like Figure 1 , Figure 2 , Figure 4 As shown in this embodiment, the top of the supporting base plate 1 is provided with an embedding groove 101 that is adapted to the lock frame 6, the two sides of the lock frame 6 are provided with lifting blocks 604, and the top of the supporting base plate 1 is provided with grooves 102 located on both sides of the top of the embedding groove 101. The lifting blocks 604 are adapted to the grooves 102.

[0045] It is understandable that by opening an embedding groove 101 and a recess 102 on the supporting base plate 1 to fit the lock frame 6 and its lifting block 604, the unlocked lock frame 6 can slide into and be stored inside the embedding groove 101. At the same time, it is convenient for the user to lift the lock frame 6 out of the embedding groove 101 by lifting the block 604 to lock the flip-up side plate 4, thereby improving the convenience and stability of use.

[0046] Preferably, the inner walls of the four sides of the lock frame 6 are provided with through grooves 602, and the size of the through grooves 602 is larger than the size of the hinge connecting the flip-up side plate 4 and the supporting base plate 1.

[0047] By providing through slots 602 on both sides of the inner wall of the four sides of the lock frame 6, the lock frame 6 can smoothly bypass the connecting hinge between the flip-up side plate 4 and the supporting base plate 1 during the sliding process, avoiding structural interference and improving the sliding flexibility and reliability of the lock frame 6.

[0048] like Figure 1 , Figure 5 As shown, the side wall of the supporting base plate 1 is provided with an inflation pipe 9 that extends into the inflation cavity 103 at one end, and a valve 10 is provided at the end of the inflation pipe 9 located outside the supporting base plate 1.

[0049] Preferably, valve 10 can be replaced with an air inlet.

[0050] The inflation tube 9 can be connected to an air pump to facilitate inflation or deflation of the inflation chamber 103. When inflated, the air pressure can push the limiting plate 74 on the outside of the limiting post 71 to abut against the inner wall of the iron core, thereby achieving the effect of internal support and limiting.

[0051] Please see Figure 6 , Figure 7 , Figure 8 In this embodiment, the limiting member 7 includes a limiting post 71 disposed on the top of the supporting base plate 1. The bottom of the limiting post 71 is provided with a connecting pipe 72 extending into the air cavity 103. The interior of the limiting post 71 is provided with a ventilated cavity 7101 communicating with the connecting pipe 72. The side wall of the limiting post 71 is provided with three telescopic members 73 at equal intervals. The telescopic member 73 includes an embedded housing 7301 embedded in the limiting post 71. A piston plate 7302 is slidably connected inside the embedded housing 7301. The side wall of the piston plate 7302 is provided with a piston rod 7303. One end of the piston rod 7303 extends through the embedded housing 7301 to the outside and is connected to a limiting abutment plate 74. The side wall of the limiting abutment plate 74 is provided with a protective pad, which may be made of rubber.

[0052] Preferably, the interior of the inflation cavity 103 is provided with a plurality of staggered support plates 105. The support plates 105 support the sealing plate 8, thereby improving the load-bearing capacity of the sealing plate 8. The staggered support plates 105 form a serpentine gas flow channel, allowing gas to enter the interior of the limiting post 71.

[0053] It should be noted that the supporting base plate 1 includes a lower base plate and a sealing plate 8. The inflation cavity 103 is opened on the lower base plate in the form of a hollow groove, and the sealing plate 8 is set in the plate groove 104 at the top of the inflation cavity 103 to seal the inflation cavity 103 and seal the inflation cavity 103 to form a cavity.

[0054] By setting up structures such as limiting post 71, connecting pipe 72 and venting cavity 7101, the connection between inflation cavity 103 and limiting member 7 is realized, so that the gas in inflation cavity 103 can be transferred to the inside of limiting post 71, thereby achieving the effect of pushing the limiting plate 74. Meanwhile, the expansion member 73 and limiting plate 74 are set on the side wall of limiting post 71, so that limiting post 71 can be adapted and adjusted according to the shape and size of the annular iron core, thereby improving the fit and stability of the inner support.

[0055] like Figure 8 As shown, an air hole 7304 is provided on the side of the embedded housing 7301 near the ventilation cavity 7101, and the limiting plate 74 is an arc-shaped plate. The limiting plate 74 of the arc-shaped plate can better adapt to the curved shape of the annular iron core.

[0056] Preferably, the top of the lock frame 6 is provided with an embedded master control button 603, and the side wall of the flip-up side panel 4 is provided with an embedded single control button 403. The master control button 603 is configured to simultaneously open and close the four second electromagnets 601 on the lock frame 6, while the single control button 403 is used to control the opening and closing of the first electromagnet 401 on the corresponding single flip-up side panel 4.

[0057] It is worth mentioning that the two sides of the flip-up side panel 4 are sloped, and the embedded single control button 403 will not obstruct the upward and downward movement of the lock frame, while the embedded master control button 603 allows the lock frame 6 to fit tightly with the limiting plate 5 to ensure the fixing effect.

[0058] Meanwhile, the master control button 603 is located at the corner of the lock frame 6. Since the length of the limiting plate 5 is less than the width of the flip-up side plate 4, there will be a certain gap at the corner of the adjacent limiting plate 5. After locking, the lock frame 6 fits against the bottom of the limiting plate 5, and the master control button 603 will be located in the gap, so that it is convenient to press the master control button 603 to unlock the lock frame 6.

[0059] The working principle of the above embodiment is as follows: Before transportation, the lock frame 6 is unlocked by the main control button 603, causing the lock frame 6 to slide into the embedded groove 101. Then, the four flip-up side plates 4 are unlocked by the single control button 403, causing the flip-up side plates 4 to flip outward and unfold, and the limiting plate 5 is supported on the ground to form a platform. Then, the annular iron core can be stacked on each limiting post 71 in sequence. After stacking, the air pump connected to the air pipe 9 is used to inflate the air chamber 103. The gas enters the ventilation chamber 7 in the limiting post 71. The airflow is diverted into the embedded housing 7301. Under the action of air pressure, the piston plate 7302 is moved, thereby causing the limiting plate 74 outside the limiting post 71 to move and abut against the inner wall of the iron core, thus providing internal support. Then, two workers pull the lifting blocks 604 on both sides to lift the lock frame 6 out of the embedded groove 101 and move it upward to fit against the bottom of the limiting plate 5. The second permanent magnet 501 can then attract the second electromagnet 601 that is not energized, thus fixing the lock frame 6 and achieving the purpose of surrounding and protecting the iron core inside.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
