Description

Technical Field

[0001] The invention belongs to the technical field of iron core transportation, and in particular relates to a supporting device for preventing the iron core of a transformer from shifting and deforming. Background Art

[0002] In the power industry, the transformer core is an important component of the transformer. There are many types and shapes of transformer cores, and each type has its unique advantages and applicable scenarios. For example, the ring core is usually ring-shaped or approximately ring-shaped, so special attention must be paid to prevent it from shifting and deforming during transportation and storage. Therefore, the core needs to be fixed and limited before transportation and corresponding protective measures must be taken.

[0003] The traditional fixing method is usually to stack the iron cores on a supporting pallet, then wrap plastic film around the outside of the iron cores to protect and fix the iron cores, and then use fixings such as splints or brackets, bolts or other connecting parts to surround and limit the iron cores. In this way, it is ensured that the iron cores will not move during transportation. However, when the iron cores wrapped with plastic film are unloaded later, the fixings need to be removed first and then the plastic film can be removed. During this period, it will take a long time to remove the plastic film and fixings, which makes the unloading process more cumbersome and reduces the unloading efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a supporting device for preventing the transformer core from shifting and deforming, so as to facilitate unloading and improve efficiency.

[0006] By adopting the above technical scheme, by designing the supporting bottom plate and the reversible side plates hinged on the four sides, as well as the limit plates and locking frames and other structures, the four reversible side plates can be unfolded to form a platform when loading and unloading the iron cores, so as to facilitate the unloading personnel to load and unload the internal iron cores and improve efficiency. The magnetic attraction of the permanent magnet and the electromagnet can be used to quickly lock and unlock the reversible side plates, thereby improving the flexibility of the supporting device. When the four reversible side plates are closed together, the iron cores will be surrounded inside to play a preliminary protective limiting effect. At the same time, the limiting parts have the effect of internal support for the iron cores stacked on the limit columns, further preventing the iron cores from being easily displaced and deformed during transportation.

[0012] By adopting the above technical solution, by arranging the first electromagnet and the first permanent magnet on the two side walls of the flip side panel, a magnetic connection between adjacent flip side panels is achieved, thereby enhancing the structural stability and overall rigidity of the supporting device. At the same time, the flip side panel on one side can be lowered according to actual needs, thereby improving the flexibility of use.

[0013] Optionally, three raising plates are provided at the bottom of the supporting base plate, the spacing between the three raising plates is the same, and the width of the limiting plate is the same as the total height of the supporting base plate and the raising plates.

[0015] Optionally, a side wall of the supporting base plate is provided with an inflation tube with one end penetrating into the inflation cavity, and a valve is provided at one 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 to facilitate inflation or deflation of the inflation cavity. During inflation, the limit abutment plate on the outside of the limit column can be pushed to contact the inner wall of the iron core under the action of air pressure, thereby achieving the effect of internal support limitation.

[0017] Optionally, the limiting member includes a limiting column arranged on the top of the supporting base plate, the bottom of the limiting column is provided with a connecting pipe extending to the inside of the inflation cavity, and the inside of the limiting column is provided with a ventilation cavity connected to the connecting pipe.

[0018] By providing structures such as the limit column, the connecting pipe and the ventilation cavity, the connection between the inflatable cavity and the limit member is achieved, so that the gas in the inflatable cavity can be transferred to the inside of the limit column, achieving the effect of pushing the limit plate.

[0019] Optionally, three telescopic parts are equidistantly arranged around the side wall of the limit column, and the telescopic parts include an embedded shell embedded in the limit column, the interior of the embedded shell is slidably connected to a piston plate, and the side wall of the piston plate is provided with a piston rod, one end of the piston rod passes through the embedded shell and extends to the outside to be connected to a limit plate.

[0020] By adopting the above technical solution, by arranging the telescopic parts and the limiting abutment plates on the side walls of the limiting columns, the limiting columns can be adjusted according to the shape and size of the annular core, thereby improving the fit and stability of the inner support.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. By designing the supporting bottom plate and the reversible side plates hinged on the four sides, as well as the limit plates and the lock frame and other structures, the four reversible side plates can be unfolded to form a platform when loading and unloading the iron cores, so as to facilitate the unloading personnel to load and unload the internal iron cores and improve efficiency. The magnetic attraction of the permanent magnet and the electromagnet is used to facilitate the rapid locking and unlocking of the reversible side plates, thereby improving the flexibility of the supporting device; 2.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figure 1 —3, the specific scheme of the embodiment is as follows: a supporting device for preventing the displacement and deformation of the transformer core, comprising a supporting bottom plate 1, the four sides of the top of the supporting bottom plate 1 are hinged with a reversible side plate 4, a limit plate 5 is arranged on the top of the reversible side plate 4, a second permanent magnet 501 is embedded in the bottom of the limit plate 5, a locking frame 6 that can slide up and down is arranged on the side wall of the reversible side plate 4, a second electromagnet 601 that can be magnetically attracted to the second permanent magnet 501 is embedded in the top of the locking frame 6, and magnetic suction parts are arranged on both sides of the reversible side plate 4, and the magnetic suction parts include The first electromagnet 401 and the first permanent magnet 402 are arranged on the two side walls of the reversible side panel 4. The first electromagnet 401 on one side of the reversible side panel 4 is magnetically attracted to the first permanent magnet 402 on the side of the adjacent reversible side panel 4. By arranging the first electromagnet 401 and the first permanent magnet 402 on the two side walls of the reversible side panel 4, a magnetic connection between adjacent reversible side panels 4 is achieved, thereby enhancing the structural stability and overall rigidity of the supporting device. At the same time, the reversible side panel 4 on one side can be lowered according to actual needs, thereby improving the flexibility of use.

[0037] It should be noted here that, as is well known, both electromagnets and permanent magnets are a type of magnet, and both have north and south magnetic fields, and two magnets with opposite poles attract each other, and with the same poles repel each other. In this embodiment, the direction of the magnetic field generated by the first electromagnet 401 after being energized is the same as the direction of the magnetic field of the side of the adjacent first permanent magnet 402 facing the direction of the first electromagnet 401, so after the first electromagnet 401 is energized, the first electromagnet 401 will generate a mutually repelling force with the adjacent first electromagnet 401.

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

[0039] When the first electromagnet 401 is not energized, the first electromagnet 401 has no suction force. However, due to its iron-containing property, when the reversible side panel 4 is erected and placed together with other reversible side panels 4, the first electromagnet 401 is attracted by the first permanent magnet 402 in contact with the first electromagnet 401, so that the two reversible side panels are placed together and stabilized. When one of the reversible side panels 4 needs to be opened, the first electromagnet 401 on the reversible side panel 4 is energized to generate an electromagnetic field. Since the electromagnetic field and the magnetic field of the adjacent first permanent magnet 402 are of the same polarity, the first electromagnet 401 and the first permanent magnet 402 are changed from an originally mutually attractive state to a mutually repulsive state, and the reversible side panel 4 can be opened.

[0040] Similarly, the second permanent magnet 501 and the second electromagnet 601 are also the same. When no power is supplied, the second permanent magnet 501 will attract the second electromagnet 601, so that the lock frame 6 is fixed at the bottom of the limit plate 5. Once power is supplied, the second electromagnet 601 will generate a magnetic field of the same polarity as the second permanent magnet 501 that repels each other, eliminating the attraction effect. At this time, the lock frame will automatically detach from the limit plate 5.

[0041] Preferably, a plurality of limit members 7 are provided on the top of the supporting base plate 1, an inflatable cavity 103 connected to the limit members 7 is provided inside the supporting base plate 1, three lifting plates 2 are provided at the bottom of the supporting base plate 1, the three lifting plates 2 have the same spacing, the width of the limit plate 5 is the same as the total height of the supporting base plate 1 and the lifting plate 2, and a power supply 3 is provided on the side wall of the lifting plate 2, so that the internal battery can be charged by plugging in the battery, and the electromagnet is energized by the battery.

[0042] Among them, the gap formed between the lifting plates 2 facilitates the insertion of the fork on the forklift into the gap to carry the supporting device. The width of the limiting plate 5 is the same as the total height of the supporting bottom plate 1 and the lifting plate 2, so that after the flip side plate 4 is unfolded, the limiting plate 5 can be supported on the ground.

[0043] By designing the supporting bottom plate 1 and the reversible side plates 4 hinged on four sides, as well as the limit plates 5 and the locking frame 6 and other structures, the four reversible side plates 4 can be unfolded to form a platform when loading and unloading the iron cores, so as to facilitate the unloading personnel to load and unload the internal iron cores and improve efficiency. The magnetic attraction of the permanent magnet and the electromagnet can be used to quickly lock and unlock the reversible side plates 4, thereby improving the flexibility of the supporting device. When the four reversible side plates 4 are closed together, the iron cores will be surrounded inside to play a preliminary protective limiting effect. At the same time, the limiting member 7 has an internal support effect on the iron cores stacked on the limit columns 71, further preventing the iron cores from being easily displaced and deformed 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 adapted to the locking frame 6, and lifting blocks 604 are provided on both sides of the locking frame 6. 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, and the lifting blocks 604 are adapted to the grooves 102.

[0045] It can be understood that by providing the embedding groove 101 and the groove 102 on the supporting base plate 1, which are adapted to the lock frame 6 and its lifting block 604, the unlocked lock frame 6 can slide into the embedding groove 101, and at the same time, it is convenient for the user to lift the lock frame 6 in the embedding groove 101 by lifting the block 604 to lock the flip side panel 4, thereby improving the convenience and stability of use.

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

[0047] By providing through grooves 602 on both sides of the inner walls of the four sides of the lock frame 6, the lock frame 6 can smoothly bypass the connecting hinge between the flip side plate 4 and the supporting bottom plate 1 during the sliding process, thereby 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 tube 9 with one end penetrating into the inflation cavity 103 , and the inflation tube 9 is provided with a valve 10 at one end outside the supporting base plate 1 .

[0049] Preferably, the valve 10 can be replaced by an inflation nozzle.

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

[0051] See also Figure 6 , Figure 7 , Figure 8 In this embodiment, the limiting member 7 includes a limiting column 71 arranged on the top of the supporting base plate 1, and a connecting pipe 72 extending to the inside of the inflation cavity 103 is provided at the bottom of the limiting column 71. A ventilation cavity 7101 connected to the connecting pipe 72 is provided inside the limiting column 71. Three telescopic members 73 are equidistantly provided around the side wall of the limiting column 71. The telescopic members 73 include an embedded shell 7301 embedded in the inside of the limiting column 71, and a piston plate 7302 is slidably connected to the inside of the embedded shell 7301. A piston rod 7303 is provided on the side wall of the piston plate 7302. One end of the piston rod 7303 passes through the embedded shell 7301 and extends to the outside to connect with the limiting abutment plate 74. The side wall of the limiting abutment plate 74 is provided with a protective pad, which can be made of rubber.

[0052] Preferably, a plurality of staggered support plates 105 are provided inside the inflation cavity 103, and the support plates 105 support the sealing plate 8, thereby improving the load-bearing capacity of the sealing plate 8, and the staggered support plates 105 form a serpentine gas flow channel, so that the gas can enter the interior of the limiting column 71.

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

[0054] By setting structures such as the limit column 71, the connecting tube 72 and the ventilation cavity 7101, the connection between the inflatable cavity 103 and the limit member 7 is achieved, so that the gas in the inflatable cavity 103 can be transmitted to the inside of the limit column 71, thereby achieving the effect of pushing the limit abutment plate 74. The telescopic member 73 and the limit abutment plate 74 are set on the side wall of the limit column 71, so that the limit column 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 one side of the embedded shell 7301 close to the ventilation cavity 7101, and the limit stop plate 74 is an arc-shaped plate. The arc-shaped limit stop plate 74 can better adapt to the curved surface shape of the annular iron core.

[0056] Preferably, an embedded master control button 603 is provided on the top of the lock frame 6, and an embedded single control button 403 is provided on the side wall of the flip side panel 4. The master control button 603 can simultaneously turn on and off 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 side panel 4.

[0057] It is worth mentioning that the two sides of the flip side panel 4 are inclined structures, and the embedded single control button 403 will not hinder the upward and downward sliding of the lock frame, while the embedded master control button 603 enables the lock frame 6 to fit tightly with the limit plate 5 to ensure the fixing effect.

[0058] At the same time, the master control button 603 is located at the corner of the lock frame 6. Since the length of the limit plate 5 is smaller than the width of the flip side plate 4, a certain gap will be left at the corners of the adjacent limit plates 5. The locked lock frame 6 will fit against the bottom of the limit plate 5, and the master control button 603 will be located in the gap, making it 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 master control button 603, so that the lock frame 6 slides down and falls into the embedded groove 101, and then the four flip-over side panels 4 are unlocked by the single control button 403, so that the flip-over side panels 4 are flipped outward and unfolded, and the limit plate 5 is supported on the ground to form a platform, and then the annular iron core can be stacked on each limit column 71 in turn. After the stacking is completed, the inflation tube 9 is connected to the air pump to inflate the inflation cavity 103, and the gas enters the ventilation cavity 7 in the limit column 71. 101 and is diverted into the embedded shell 7301, and under the action of air pressure, the piston plate 7302 is pushed to move, so that the limiting abutment plate 74 outside the limiting column 71 moves and abuts against the inner wall of the iron core, playing the role of internal support, and then two staff members pull the lifting blocks 604 on both sides to lift the lock frame 6 out of the embedded groove 101 and move it up to fit the bottom of the limiting plate 5, and the second permanent magnet 501 can absorb the unpowered second electromagnet 601, so that the lock frame 6 is fixed, thereby achieving the purpose of surrounding and protecting the iron core inside.

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