Description

Technical Field

[0001] This invention belongs to the field of transformer coil transfer technology, and particularly relates to a transport device for transformer coils. Background Technology

[0002] With the increase in the capacity and weight of single transformers and the increasing complexity of the transportation environment, transformer on-site assembly technology has emerged in transformer production technology. On-site assembly is based on transportation. The transformer is disassembled and transported to the installation site for on-site assembly. A crucial part of the transportation process is the transport of the transformer coils, which requires consideration of various risks such as moisture protection, foreign object protection, and impact damage.

[0003] The existing transformer coil needs to be transported. The transformer coil is placed inside the transport device for transport. When the transformer coil encounters complex roads during transport, it is prone to bumps. In severe cases, the transformer coil may detach from the transport device, causing damage to the transformer coil. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transport device for transformer coils. This device can not only store transformer coils to achieve the purpose of transporting transformer coils, but also facilitates the placement and lifting of transformer coils by the lifting component. It can more conveniently place transformer coils into the housing. At the same time, the cooperation of the pressing component, the first clamping rod and the second clamping rod can fix the transformer coils and ensure the safety of the transformer coils during transportation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A transport device for transformer coils includes a housing, a sealing cover, and a locking mechanism. The sealing cover is located on the top of the housing, and one side of the sealing cover is connected to the housing via a hinge. The two ends of the locking mechanism are respectively connected to the other side of the sealing cover and the housing. Inside the housing, a lifting assembly and a clamping mechanism are installed. The lifting assembly is mounted on the bottom plate of the housing. The clamping mechanism includes a first clamping rod, a second clamping rod, and a reset mechanism. The bottoms of the first and second clamping rods are rotatably mounted on the bottom wall of the housing. The first and second clamping rods are symmetrically arranged on both sides of the center line of the housing. There are two second clamping rods, each located on one side of the first clamping rod. The reset mechanism is connected to both the first and second clamping rods. The lifting assembly, in conjunction with the first and second clamping rods, positions and fixes the transformer coil to be transported. A pressing mechanism is also installed at the bottom of the sealing cover, which cooperates with the first and second clamping rods.

[0007] Preferably, the reset mechanism includes a lifting plate, a pull rod, a guide column, a first spring, and a sealing block. The guide column is fixedly installed on the bottom plate of the housing, the lifting plate is slidably installed on the guide column, the pull rod is symmetrically arranged at both ends of the lifting plate, one end of the pull rod is connected to the lifting plate, and the other end of the pull rod is connected to the first clamping rod or the second clamping rod. The sealing block is fixedly installed on the top of the guide column, the first spring is sleeved on the guide column, and the first spring is located between the lifting plate and the sealing block. The reset mechanism is used to drive the first clamping rod and the second clamping rod to reset, ensuring the normal operation of the first clamping rod and the second clamping rod.

[0008] Preferably, the lifting assembly includes a scissor lifting mechanism and a placement plate. The two ends of the scissor lifting mechanism are respectively installed on the bottom plate of the housing and the bottom of the placement plate. A limit hole is opened in the middle of the placement plate. The limit hole cooperates with the first clamping rod and the second clamping rod. The placement plate is set to support the transformer coil and ensure the safety of the transformer coil during transportation. The scissor lifting mechanism can drive the transformer coil to lift and lower, which facilitates the hoisting of the transformer coil when installing it.

[0009] Preferably, the locking component includes a pulling mechanism, a fixed plate, a sliding block, a lead screw, and a first internal hexagonal nut fixedly installed at the end of the lead screw. The pulling mechanism is rotatably installed on the other side of the sealing cover. The fixed plate is fixedly installed on the side of the housing, with a through hole on the fixed plate and an adjustment hole on the side wall of the through hole. The two ends of the lead screw are rotatably installed on the two side walls of the through hole, respectively. The first internal hexagonal nut is located below the fixed plate. The sliding block is slidably installed in the through hole and threaded onto the lead screw. A limit rod is also installed on the sliding block, which slides in cooperation with the adjustment hole. The pulling mechanism cooperates with the limit rod. By rotating the first internal hexagonal nut, the lead screw is driven to rotate. The rotation of the lead screw causes the sliding block to move along the through hole. The movement of the lead screw along the through hole causes the limit rod on the sliding block to move. The movement of the limit rod pulls the pulling mechanism installed on the cover plate downward, thereby fixing the sealing cover to the top of the housing.

[0010] Preferably, the pulling mechanism includes a fixed base, a rotating rod, and a handle. The fixed base is fixedly installed on the other side of the sealing cover. The rotating rod is symmetrically arranged on both sides of the fixed base and rotatably installed on the fixed base. The handle is fixedly installed at the end of the rotating rod. A limiting groove is also opened on the limiting rod. The handle cooperates with the limiting groove. The setting of the limiting groove can prevent the handle from sliding relative to the limiting rod during operation, which would affect the normal operation of the sealing cover. Under the action of the lead screw, sliding block, and limiting rod, the handle and the rotating rod can be pulled down, so that the sealing cover is sealed on the top of the box.

[0011] Preferably, the pressing component includes a fixed block, a threaded rod, a slider, a rotating arm, and a pressing plate. The fixed block is fixedly installed in the middle of the sealing cover, and mounting seats are provided on both sides of the center line of the sealing cover. The two ends of the threaded rod are respectively rotatably installed on the mounting seats provided on both sides of the center line of the sealing cover, and the middle part of the threaded rod is rotatably installed on the fixed block. The threads on both sides of the center line of the threaded rod have opposite directions. A second hexagonal socket nut is fixedly installed at both ends of the threaded rod. The slider is symmetrically arranged on both sides of the fixed block, and the slider is threadedly connected to the threaded rod. The pressing plate is provided on the threaded rod. Below the rod, the rotating arms are symmetrically arranged on both sides of the fixed block. One end of the rotating arm is rotatably mounted on the lower pressure plate, and the other end of the rotating arm is rotatably mounted on the sliders symmetrically arranged on both sides of the fixed block. By rotating the second internal hex nut, the threaded rod is driven to rotate. The rotation of the threaded rod drives the slider to move towards the fixed block at the same time. As the slider moves, it will drive one end of the rotating arm to move towards the fixed block, and the other end of the rotating arm will press down on the pressure plate, so that the lower pressure plate cooperates with the first clamping rod and the second clamping rod to achieve the purpose of fixing the first clamping rod and the second clamping rod.

[0012] Preferably, an inclined surface is provided on the side wall of the lower pressure plate, and a clearance groove is provided on the side wall of the housing near both ends of the threaded rod. The clearance groove cooperates with the second internal hexagonal nut. The inclined surface ensures that the side wall of the lower pressure plate can fit more closely to the first clamping rod and the second clamping rod. The clearance groove can avoid the second internal hexagonal nut and prevent the second internal hexagonal nut from interfering with the side wall of the housing during operation.

[0013] Preferably, the device also includes a positioning component, which comprises a fixing ring, a push rod, a positioning rod, and a fixing frame. The fixing frame is fixedly installed on the side wall of the box, the fixing ring and the fixing frame are installed on the same straight line and connected to the side wall of the box, the positioning rod is slidably installed on the fixing frame, and a through hole is opened on the bottom plate of the box, which cooperates with the positioning rod. The push rod is located on one side of the fixing frame and is rotatably installed on the side wall of the box. When the device needs to be stacked, the push rod cooperates with the positioning rod, the push rod pushes the positioning rod to move downward, and the positioning rod moves downward and inserts into the fixing ring on the lower box, thereby achieving the purpose of fixing the stacked boxes.

[0014] Preferably, the fixing frame includes a top plate and side plates installed at both ends of the top plate. The top plate and side plates are fixedly installed on the outer wall of the box. A strip hole is opened on the side plate. The positioning rod is slidably disposed between the side plates at both ends of the top plate. A groove is opened at the top of the positioning rod. A fixing post is fixedly installed inside the groove. Guide grooves are opened on both sides of the positioning rod. A guide rail is installed on the inner wall of the side plate. The guide rail is slidably engaged with the guide groove. One end of the push rod is disposed in the strip hole on the side plate. A strip groove is opened on the push rod. The fixing post is disposed in the strip groove and is slidably engaged with the strip groove. The fixing frame is used to guide the positioning rod and can ensure the normal operation of the positioning rod. The strip groove on the push rod cooperates with the fixing post to ensure that the positioning rod can be moved when the push rod is rotated, thereby inserting the positioning rod on the upper box into the fixing ring on the side wall of the box stacked below.

[0015] Preferably, a mounting hole is provided at a position slightly below the middle of the positioning rod. A limiting mechanism is installed in the mounting hole. The limiting mechanism includes a telescopic rod, a second spring, a mounting block, and a limiting block. The mounting block is fixedly installed in the middle of the mounting hole. The telescopic rod, the second spring, and the limiting block are symmetrically arranged on both sides of the mounting block. The two ends of the telescopic rod are respectively fixedly installed on the limiting block and the mounting block. The second spring is sleeved on the telescopic rod, and the two ends of the second spring are respectively connected to the limiting block and the mounting block. The limiting mechanism can limit and fix the stacked boxes, preventing the upper box from tipping over or tilting during transportation, thus greatly ensuring the safety of the transformer coil.

[0016] Preferably, a hand-tightening bolt is also installed on the push rod, and a fixing groove is opened on the side wall of the housing. The hand-tightening bolt cooperates with the fixing groove, and the push rod can be fixed by the hand-tightening bolt and the fixing groove, so as to ensure the stability and safety of the positioning component during the operation.

[0017] The beneficial effects of this invention are:

[0018] This device not only stores transformer coils for transportation, but also features a lifting assembly that facilitates the placement and lifting of the coils, making it easier to place them inside the housing. Furthermore, the combined action of the lowering component, the first clamping rod, and the second clamping rod secures the transformer coils, ensuring their safety during transport.

[0019] The reset mechanism of this device is used to reset the first clamping rod and the second clamping rod, ensuring the normal operation of the first clamping rod and the second clamping rod.

[0020] The placement plate of this device is used to support the transformer coil and ensure its safety during transportation. The scissor lifting mechanism can drive the transformer coil to lift and lower, making it convenient to hoist the transformer coil during installation.

[0021] This device rotates the first internal hexagonal nut to drive the lead screw to rotate. The rotation of the lead screw causes the sliding block to move along the through hole. The movement of the lead screw along the through hole causes the limit rod on the sliding block to move. The movement of the limit rod causes the pulling mechanism installed on the cover plate to move downward, thereby fixing the sealing cover to the top of the box.

[0022] The limiting groove of this device can prevent the handle from sliding relative to the limiting rod during operation, which would affect the normal operation of the sealing cover. Under the action of the lead screw, sliding block and limiting rod, the handle and rotating rod can be pulled down, so that the sealing cover is sealed at the top of the box.

[0023] This device rotates the threaded rod by rotating the second internal hex nut. The rotation of the threaded rod causes the slider to move towards the fixed block. As the slider moves, one end of the rotating arm moves towards the fixed block, and the other end of the rotating arm presses down on the pressure plate. This causes the pressure plate to cooperate with the first clamping rod and the second clamping rod to fix the first clamping rod and the second clamping rod.

[0024] The inclined surface of this device ensures that the side wall of the lower pressure plate can fit more closely to the first and second clamping rods, and the clearance groove can avoid the second internal hexagonal nut, preventing the second internal hexagonal nut from interfering with the side wall of the housing during operation.

[0025] When the devices need to be stacked, the push rod and the positioning rod cooperate. The push rod pushes the positioning rod downward, and the positioning rod moves downward and inserts into the fixing ring on the lower box, thereby achieving the purpose of fixing the stacked boxes.

[0026] The mounting bracket of this device is used to guide the positioning rod and ensure its normal operation. The slot on the push rod cooperates with the fixed column to ensure that the positioning rod can be moved when the push rod is rotated, thereby inserting the positioning rod on the upper box into the fixing ring on the side wall of the box stacked below.

[0027] The limiting mechanism of this device can limit and fix stacked boxes, preventing the upper box from tipping over or tilting during transportation, thus greatly ensuring the safety of the transformer coil. Attached Figure Description

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.

[0053] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0054] like Figure 1 , Figure 2 , Figure 3 As shown, a transport device for transformer coils includes a housing 1, a sealing cover 3, and a locking component 2. The sealing cover 3 is located on the top of the housing 1, and one side of the sealing cover 3 is connected to the housing 1 via a hinge. To ensure the sealing performance of the device, a rubber sealing gasket can be provided at the connection between the sealing cover 3 and the housing 1. The two ends of the locking component 2 are respectively connected to the other side of the sealing cover 3 and the housing 1. Inside the housing 1, a lifting assembly 5 and a clamping component 6 are installed. The lifting assembly 5 is installed on the bottom plate of the housing 1. The lifting assembly 5 facilitates the placement of the transformer coil inside the housing 1 and also facilitates the removal of the transformer coil from the housing 1, thereby improving the efficiency of transformer coil transport.

[0055] As an optimized solution of the present invention, such as Figure 9 As shown, the clamping component 6 includes a first clamping rod 602, a second clamping rod 603, and a reset mechanism 601. The bottoms of the first clamping rod 602 and the second clamping rod 603 are rotatably mounted on the bottom wall of the housing 1. The first clamping rod 602 and the second clamping rod 603 are symmetrically arranged on both sides of the center line of the housing 1. There are two second clamping rods 603, which are respectively arranged on both sides of the first clamping rod 602. The reset mechanism 601 is connected to the first clamping rod 602 and the second clamping rod 603 respectively. The lifting component 5 works with the first clamping rod 602 and the second clamping rod 603 to position and fix the transformer coil to be transported.

[0056] like Figure 3 As shown, a pressing component 7 is also installed at the bottom of the sealing cover 3. The pressing component 7 cooperates with the first clamping rod 602 and the second clamping rod 603. The setting of the pressing component 7 ensures that the first clamping rod 602 and the second clamping rod 603 can fix transformer coils of different sizes, which greatly improves the applicable scenarios of the device.

[0057] As an optimized solution of the present invention, such as Figure 10As shown, the reset mechanism 601 includes a lifting plate 604, a pull rod 608, a guide post 606, a first spring 605, and a sealing block 607. The guide post 606 is fixedly installed on the bottom plate of the housing 1. The lifting plate 604 is slidably installed on the guide post 606. The pull rod 608 is symmetrically arranged at both ends of the lifting plate 604. One end of the pull rod 608 at both ends of the lifting plate 604 is connected to the lifting plate 604, and the other end of the pull rod 608 is connected to the first clamping rod 602 or the second clamping rod 603. The sealing block 607 is fixedly installed on the top of the guide post 606. The first spring 605 is sleeved on the guide post 606 and is located between the lifting plate 604 and the sealing block 607. The first spring 605 is used to drive the lifting plate 604 to reset, ensuring the normal operation of the first clamping rod 602 and the second clamping rod 603.

[0058] The reset mechanism 601 is used to drive the first clamping rod 602 and the second clamping rod 603 to reset, so as to ensure the normal operation of the first clamping rod 602 and the second clamping rod 603.

[0059] As an optimized solution of the present invention, such as Figure 8 As shown, the lifting assembly 5 includes a scissor lifting mechanism 501 and a placement plate 502. The two ends of the scissor lifting mechanism 501 are respectively installed on the bottom plate of the housing 1 and the bottom of the placement plate 502. A limiting hole 503 is opened in the middle of the placement plate 502. The limiting hole 503 cooperates with the first clamping rod 602 and the second clamping rod 603.

[0060] The placement plate 502 is used to support the transformer coil and ensure its safety during transportation. The scissor lifting mechanism 501 can drive the transformer coil to lift and lower, making it convenient to place the transformer coil inside the housing 1 or take it out of the housing 1. It also facilitates the hoisting of the transformer coil during installation.

[0061] As an optimized solution of the present invention, such as Figure 4 , Figure 5 , Figure 6As shown, the locking component 2 includes a pulling mechanism 201, a fixing plate 202, a sliding block 204, a lead screw 203, and a first internal hexagon nut 205 fixedly installed at the end of the lead screw 203. The pulling mechanism 201 is rotatably installed on the other side of the sealing cover 3. The fixing plate 202 is fixedly installed on the side of the housing 1. A through hole 208 is opened on the fixing plate 202, and an adjustment hole 209 is opened on the side wall of the through hole 208. The two ends of the lead screw 203 are respectively rotatably installed on the two side walls of the through hole 208. The first internal hexagon nut 205 is located below the fixing plate 202. The sliding block 204 is slidably installed in the through hole 208, and the sliding block 204 is threaded onto the lead screw 203. A limit rod 207 is also installed on the sliding block 204. The limit rod 207 is slidably engaged with the adjustment hole 209. The pulling mechanism 201 is engaged with the limit rod 207.

[0062] By rotating the first internal hex nut 205, the lead screw 203 is driven to rotate. The rotation of the lead screw 203 causes the sliding block 204 to move along the through hole 208. The movement of the lead screw 203 along the through hole 208 will cause the limiting rod 207 on the sliding block 204 to move. The movement of the limiting rod 207 will pull the pulling mechanism 201 installed on the cover plate to move downward, thereby fixing the sealing cover 3 to the top of the box 1.

[0063] As an optimized solution of the present invention, such as Figure 7 As shown, the pulling mechanism 201 includes a fixed base 2010, a rotating rod 2011, and a handle 2012. The fixed base 2010 is fixedly installed on the other side of the sealing cover 3. The rotating rod 2011 is symmetrically arranged on both sides of the fixed base 2010 and is rotatably installed on the fixed base 2010. The handle 2012 is fixedly installed on the end of the rotating rod 2011. A limiting groove 206 is also opened on the limiting rod 207, and the handle 2012 cooperates with the limiting groove 206.

[0064] The setting of the limiting groove 206 can prevent the handle 2012 from sliding relative to the limiting rod 207 during operation, which would affect the normal operation of the sealing cover 3. Under the action of the lead screw 203, the sliding block 204 and the limiting rod 207, the rod 608, handle 2012 and rotating rod 2011 can be pulled down, so that the sealing cover 3 is sealed on the top of the box 1.

[0065] As an optimized solution of the present invention, such as Figure 15As shown, the pressing component 7 includes a fixing block 704, a threaded rod 701, a slider 703, a rotating arm 705, and a pressing plate 706. The fixing block 704 is fixedly installed in the middle of the sealing cover 3. Mounting seats 707 are provided on both sides of the center line of the sealing cover 3. The mounting seats 707 facilitate the installation of the threaded rod 701 and ensure the normal operation of the threaded rod 701. In order to ensure the sealing performance of the device, a sealing gasket can also be provided between the mounting seat 707 and the inner wall of the housing 1.

[0066] The two ends of the threaded rod 701 are rotatably mounted on the mounting seats 707 located on both sides of the center line of the sealing cover 3. The middle part of the threaded rod 701 is rotatably mounted on the fixed block 704. The threads on both sides of the center line of the threaded rod 701 have opposite directions, which facilitates the simultaneous movement of the sliders 703 on both sides of the fixed block 704 to the sides or to the center, thereby achieving the purpose of driving the lower pressure plate 706 to rise or fall, ensuring the normal operation of the lower pressure plate 706. A second internal hexagonal nut 702 is fixedly installed at both ends of the threaded rod 701. The sliders 703 are symmetrically arranged on both sides of the fixed block 704, and the sliders 703 are threadedly connected to the threaded rod 701. The lower pressure plate 706 is located below the threaded rod 701. The rotating arms 705 are symmetrically arranged on both sides of the fixed block 704. One end of the rotating arm 705 is rotatably mounted on the lower pressure plate 706, and the other end of the rotating arm 705 is rotatably mounted on the sliders 703 symmetrically arranged on both sides of the fixed block 704.

[0067] By rotating the second internal hex nut 702, the threaded rod 701 is driven to rotate. The rotation of the threaded rod 701 drives the slider 703 to move towards the fixed block 704. As the slider 703 moves, one end of the rotating arm 705 moves towards the fixed block 704. The other end of the rotating arm 705 presses down on the pressure plate 706, so that the pressure plate 706 cooperates with the first clamping rod 602 and the second clamping rod 603 to achieve the purpose of fixing the first clamping rod 602 and the second clamping rod 603.

[0068] As an optimized solution of the present invention, such as Figure 15 As shown, an inclined surface is provided on the side wall of the lower pressure plate 706, such as... Figure 11 As shown, clearance grooves 101 are provided on the side walls of the housing 1 near both ends of the threaded rod 701, and the clearance grooves 101 cooperate with the second internal hexagonal nut 702.

[0069] The inclined surface ensures that the side wall of the lower pressure plate 706 can fit more closely to the first clamping rod 602 and the second clamping rod 603. The clearance groove 101 can avoid the second internal hexagonal nut 702 and prevent the second internal hexagonal nut 702 from interfering with the side wall of the housing 1 during operation.

[0070] As an optimized solution of the present invention, such as Figure 11 As shown, it also includes a positioning component 4, which includes a fixing ring 401, a push rod 4011, a positioning rod 405, and a fixing frame 406. The fixing frame 406 is fixedly installed on the side wall of the housing 1. The fixing ring 401 and the fixing frame 406 are installed on the same straight line and are connected to the side wall of the housing 1. The positioning rod 405 is slidably installed on the fixing frame 406. A through hole (not shown in the figure) is opened on the bottom plate of the housing 1. The through hole cooperates with the positioning rod 405. The through hole facilitates the passage of the positioning rod 405 and ensures the normal operation of the positioning rod 405. The push rod 4011 is located on one side of the fixing frame 406 and is rotatably installed on the side wall of the housing 1.

[0071] When the device needs to be stacked, the push rod 4011 cooperates with the positioning rod 405. The push rod 4011 pushes the positioning rod 405 downward, and the positioning rod 405 moves downward and inserts into the fixing ring 401 on the lower box 1, thereby achieving the purpose of fixing the stacked box 1.

[0072] As an optimized solution of the present invention, such as Figure 12 As shown, the fixing frame 406 includes a top plate 407 and side plates 4010 installed at both ends of the top plate 407. The top plate 407 and side plates 4010 are fixedly installed on the outer wall of the housing 1. A strip hole 408 is opened in the side plate 4010. The positioning rod 405 is slidably disposed between the side plates 4010 at both ends of the top plate 407. A groove 4013 is opened on the top of the positioning rod 405, and a fixing post 4 is fixedly installed inside the groove 4013. 016, guide grooves 4014 are opened on both sides of the positioning rod 405, and guide rails 409 are installed on the inner wall of the side plate 4010. The guide rails 409 are slidably engaged with the guide grooves 4014. One end of the push rod 4011 is set in the strip hole 408 on the side plate 4010. A strip groove 4012 is opened on the push rod 4011, and a fixing post 4016 is set in the strip groove 4012, and the fixing post 4016 is slidably engaged with the strip groove 4012.

[0073] The fixing bracket 406 is used to guide the positioning rod 405 and ensure the normal operation of the positioning rod 405. The strip groove 4012 on the push rod 4011 cooperates with the fixing column 4016 to ensure that the positioning rod 405 can be moved when the push rod 4011 is rotated, so that the positioning rod 405 on the upper box 1 is inserted into the fixing ring 401 on the side wall of the lower box 1.

[0074] As an optimized solution of the present invention, such as Figure 13 , Figure 14As shown, a mounting hole 4015 is provided at a position slightly below the middle of the positioning rod 405. A limiting mechanism 404 is installed in the mounting hole 4015. The limiting mechanism 404 includes a telescopic rod 4020, a second spring 4018, a mounting block 4017, and a limiting block 4019. The mounting block 4017 is fixedly installed in the middle of the mounting hole 4015. The telescopic rod 4020, the second spring 4018, and the limiting block 4019 are symmetrically arranged on both sides of the mounting block 4017. The two ends of the telescopic rod 4020 are respectively fixedly installed on the limiting block 4019. On the positioning block 4019 and mounting block 4017, the second spring 4018 is sleeved on the telescopic rod 4020, and the two ends of the second spring 4018 are respectively connected to the limiting block 4019 and the mounting block 4017. The second spring 4018 is used to pop out the limiting block 4019, thereby ensuring that the limiting block 4019 can always be in the popped-out state during the operation, and the limiting block 4019 always cooperates with the bottom of the fixing ring 401, thereby fixing the stacked box 1, which greatly ensures the safety of the box 1 during transportation.

[0075] The limiting mechanism 404 can limit and fix the stacked boxes 1, preventing the upper box 1 from tipping over or tilting during transportation, thus greatly ensuring the safety of the transformer coil.

[0076] As an optimized solution of the present invention, such as Figure 11 As shown, a hand-tightening bolt 403 is also installed on the push rod 4011, and a fixing groove 402 is opened on the side wall of the housing 1. The hand-tightening bolt 403 cooperates with the fixing groove 402.

[0077] The hand-tightening bolt 403, in conjunction with the fixing groove 402, can be used to fix the push rod 4011, ensuring the stability and safety of the positioning component 4 during operation.

[0078] Example 1

[0079] The scissor lifting mechanism 501 is controlled to raise the placement plate 502 until its upper surface is flush with the top of the housing 1. The transformer coil to be transported is placed on the placement plate 502, and initial adjustments are made to ensure that the middle of the transformer coil is aligned with the limiting hole 503 in the middle of the placement plate 502. The scissor lifting mechanism 501 then lowers the placement plate 502, which in turn lowers the transformer coil into the housing 1 until it is completely submerged inside. During the descent of the scissor lifting mechanism 501, the first... A clamping rod 602 and a second clamping rod 603 extend through the limiting hole 503 and the hole in the middle of the transformer coil to the top of the transformer coil. The scissor lifting mechanism 501 continues to move downward. Under the action of the inner wall of the limiting hole 503, it will drive the first clamping rod 602 and the second clamping rod 603 to rotate, so that the upper ends of the first clamping rod 602 and the second clamping rod 603 continue to move outward, so that the side walls of the first clamping rod 602 and the second clamping rod 603 contact the inner wall of the hole in the middle of the transformer coil, and fix the transformer coil from the inside.

[0080] Pulling the handle 2012 causes the rotating rod 2011 to rotate around the fixed base 2010, so that the handle 2012 is located in the limiting groove 206 on the limiting rod 207. Rotating the first internal hex nut 205 causes the lead screw 203 to rotate. The rotation of the lead screw 203 causes the sliding block 204 to move along the through hole 208. The movement of the lead screw 203 along the through hole 208 will cause the limiting rod 207 on the sliding block 204 to move. The movement of the limiting rod 207 will pull the handle 2012 installed on the cover plate to move downward. The downward movement of the handle 2012 will cause the rotating rod 2011 to move downward. The pulling rod 608 will pull the sealing cover 3 downward, thereby fixing the sealing cover 3 on the top of the box 1.

[0081] Example 2

[0082] The second hexagonal nut 702 is rotated by a wrench or electric wrench. The rotation of the second hexagonal nut 702 will drive the threaded rod 701 to rotate. The rotation of the threaded rod 701 will drive the sliders 703 located on both sides of the fixed block 704 to move towards the center. As the sliders 703 move, one end of the rotating arm 705 will move towards the fixed block 704. The other end of the rotating arm 705 will press down on the pressure plate 706, so that the pressure plate 706 cooperates with the first clamping rod 602 and the second clamping rod 603. The downward movement of the pressure plate 706 will drive the upper ends of the first clamping rod 602 and the second clamping rod 603 to separate in opposite directions, so that the first clamping rod 602 and the second clamping rod 603 fix the transformer coil on the placement plate 502, preventing the transformer coil from shaking when encountering complex road sections and ensuring the safety of the transformer coil during transportation.

[0083] Example 3

[0084] like Figure 16 As shown, when stacking the housing 1 containing the transformer coil, the worker places the housing 1 containing the transformer coil onto the sealing cover 3 on top of the housing 1 on the ground. After the upper housing 1 is placed, the push rod 4011 is rotated to move the positioning rod 405 downward. The downward movement of the positioning rod 405 causes the positioning rod 405 on the upper housing 1 to move into the fixing ring 401 on the lower housing 1. When the limiting mechanism 404 at the bottom of the positioning rod 405 moves to below the fixing ring 401, the limiting block 4019 pops out from the mounting hole 4015 under the action of the second spring 4018 and the telescopic rod 4020, so that the limiting block 4019 cooperates with the bottom of the fixing ring 401. This prevents the upper positioning rod 405 from being pulled out of the positioning ring during the movement, which would affect the safety of the transformer coil during transportation. This achieves the purpose of binding the upper and lower housing 1 together, preventing the upper housing 1 from tilting due to bumps during the transportation of the transformer coil, which would affect the safety of the transformer coil.

[0085] Example 4

[0086] After the push rod 4011 moves to the appropriate position, the hand screw 403 is rotated to make the hand screw 403 penetrate into the fixing groove 402, thereby fixing the push rod 4011. This prevents the push rod 4011 from rotating during the transportation of the transformer coil and affecting the normal operation of the positioning rod 405. It also prevents the positioning rod 405 from moving too far downward, exceeding the limit of the push rod 4011 on the positioning rod 405, thus ensuring the normal operation of the device.

[0087] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
