Abstract
Description
Technical Field
[0001] This invention relates to the field of hoisting technology, and in particular to a coil frame processing hoisting equipment and hoisting method. Background Technology
[0002] Crane operation is an industrial process of transporting machinery or other objects from one place to another. Most cranes begin their vertical or combined vertical and horizontal working stroke after the lifting device picks up the material. Upon reaching the destination, they unload, then travel empty back to the picking location, completing one work cycle, before starting the next lifting operation. Generally, during crane operation, picking, moving, and unloading are performed sequentially, with the operation of each corresponding mechanism intermittent. Cranes are mainly used for handling packaged goods; equipped with grab buckets, they can handle bulk materials such as coal, ore, and grain; equipped with buckets, they can lift molten steel and other liquid materials. Some cranes, such as elevators, can also be used to carry people. In certain applications, cranes are the primary working machinery; for example, cranes used for loading and unloading materials in ports and railway stations are the main working machinery.
[0003] Patent application CN103043524A discloses a coil lifting device, which includes a central seat and at least three radially extending cross arms spaced apart along the circumference of the central seat, each cross arm being provided with a hook. Each cross arm is rotatable relative to the central seat. The cross arms are retractable toward the central axis of the central seat. Each cross arm is provided with multiple teeth. It includes four radially extending cross arms evenly arranged along the circumference of the central seat.
[0004] However, in actual use, for a certain type of coil frame, the lifting process will cause wear on the surface of the coil frame, and the coil frame may tilt during the lifting and movement, which may lead to deformation of the coil frame. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up fastening and balancing mechanisms to achieve tight fixation and stability of the coil frame's center of gravity, thereby preventing wear on the coil frame during hoisting and maintaining the stability of the coil frame's center of gravity at all times to avoid the risk of tilting or deformation. This also solves the technical problem of easy wear and tilting of the coil frame's surface during hoisting.
[0006] To address the above technical issues, the following technical solution is adopted:
[0007] A coil bobbin processing and lifting device and lifting method, comprising:
[0008] A positioning mechanism, comprising a lifting frame and a positioning component, is used to position and fix the coil frame;
[0009] A fastening mechanism, located below the positioning mechanism, is used to fix the lifting frame to the coil frame;
[0010] A reinforcing mechanism is located in the middle of the positioning mechanism and is used to further enhance the fixing effect of the fastening mechanism;
[0011] A balancing mechanism is located within a positioning mechanism and is used to connect the hoisting cable to the positioning mechanism. The balancing mechanism includes a connector, multiple sets of measuring components, and multiple sets of adjusting components. The connector is used to connect the hoisting cable to the positioning mechanism. The measuring components and adjusting components cooperate to adjust the angle of the connector and change the center of gravity of the positioning mechanism.
[0012] Preferably, the positioning components are provided in multiple sets and arrayed on the upper end of the lifting frame, including a contact plate vertically slidably connected to the upper end of the lifting frame, side plates disposed on both sides of the contact plate and intersecting on the lifting frame, a rack fixed to the upper end of the contact plate and having teeth on both sides, a first gear meshing with the rack and rotatably connected to the lifting frame, and a transmission belt connecting the rotating shaft of the first gear and the hinge shaft of the side plate.
[0013] Preferably, the fastening mechanism includes a fixing component, a control component, and a stabilizing component. The fixing component includes multiple sets of support plates arranged below the hoisting frame and whose shape matches the coil frame, a movable block hinged to the upper end of the support plate, and a first motor whose output shaft is fixedly connected to the hinge shaft of the support plate and fixedly mounted on the movable block.
[0014] Preferably, the control component includes a support rod fixed to the moving block and slidably connected to the hoisting frame, a rotating plate rotatably connected to the hoisting frame and having multiple track grooves, a control rod fixed to the support rod and located in the rotating grooves, and a second motor whose output shaft is fixedly connected to the lower end of the rotating plate and fixedly connected to the hoisting frame.
[0015] Preferably, the stabilizer is fixedly connected to the outside of the hoisting frame and is arranged in multiple groups, including a stabilizer block fixedly connected to the lower end of the hoisting frame, a clamping plate rotatably connected to the stabilizer block, and a third motor whose output shaft is fixedly connected to the rotating shaft of the clamping plate.
[0016] Preferably, the reinforcing mechanism includes multiple sets of reinforcing plates that are horizontally slidably connected to the middle of the hoisting frame, a threaded rod that is rotatably connected to the middle of the hoisting frame and threaded to the lower end of the reinforcing plate, a bevel gear that is fixedly connected to the end of the threaded rod away from the reinforcing plate, a gear ring that meshes with all the bevel gears and is rotatably connected to the hoisting frame, and a fourth motor whose output shaft is fixedly connected to the rotating shaft of the gear ring and fixedly mounted on the hoisting frame.
[0017] Preferably, the balancing mechanism includes a connector, a measuring component, and an adjusting component. The connector includes a lifting rod for connecting to the lifting cable, a universal joint fixedly connected to the lower end of the lifting rod, and a balance plate connected to the lower end of the universal joint and used to connect the universal joint to the lifting frame.
[0018] Preferably, the measuring element includes
[0019] An inclined tube is fixedly connected to a balance plate and is inclined, with the outer end of the inclined tube being higher than the inner end of the inclined tube.
[0020] Ball bearings, which are disposed inside an inclined tube and roll freely within the inclined tube;
[0021] An elastic block is disposed at the outer end of the inclined tube, with one end of the elastic block extending into the inclined tube and a contact switch disposed on the outside.
[0022] Preferably, the adjusting component includes a pulley fixed to the lifting rod, a cable with one end fixed to the balance plate and passing through the pulley, a coil winding fixed to the other end of the cable and used for winding the cable, and a fifth motor whose output shaft is fixedly connected to the coil winding and controlled by a contact switch on the elastic block.
[0023] As a further preferred embodiment, the hoisting steps of the coil frame processing and hoisting equipment are as follows:
[0024] Step 1, Positioning Step: The lifting frame moves down, so that the coil frame is surrounded by the lifting frame. The contact plate of the upper section of the lifting frame contacts the upper end face of the coil frame, causing the contact plate to move up and drive the side plate to rotate, clamping the coil frame, thus achieving the initial fixation of the coil and the positioning of the lifting frame.
[0025] Step two, the fastening step: The second motor drives the rotating plate to slide the support rod outward. The support plate drives the fixing piece to approach the coil frame and fit tightly against the bottom of the coil frame to fix the coil frame. At the same time, the stabilizing component is activated, and the third motor drives the clamping plate to rotate. The clamping plate engages with the fixing piece. The fourth motor in the strengthening mechanism drives the reinforcing plate to move outward and fit against the inner wall of the coil frame to further fix the coil and ensure the stability of the coil frame during hoisting.
[0026] Step 3, balancing step: The coil frame is lifted along with the lifting equipment. When the coil frame is moved horizontally, it tilts due to inertia. When the tilt angle exceeds a certain limit, the ball bearings in the tilting tube on the tilted side roll and contact the elastic block, causing the elastic block to move and triggering the contact switch. The fifth motor starts and retracts the cable. The cable shortens, causing the balance plate to tilt relative to the lifting rod, bringing the coil frame back to a vertical position relative to the horizontal plane. At this point, the ball bearings disengage from the elastic block, the cable retraction stops, and the center of the coil frame is stabilized.
[0027] The beneficial effects of this invention are:
[0028] (1) In this invention, by setting a positioning mechanism, the lifting frame can be perfectly fitted onto the coil frame, avoiding deviation in the falling position of the lifting frame, which would affect the subsequent fastening steps. At the same time, the coil frame is clamped and fixed, and the initial fixation between the coil frame and the lifting frame is completed.
[0029] (2) In this invention, by setting a fastening mechanism, the coil frame is fully fixed, avoiding wear on the coil frame during the fixing process. At the same time, by setting a fixing component, the support plate can rotate upward, thereby preventing the support plate from colliding with the sleepers or pallets on which the coil frame is placed during the movement. The support plate moves flexibly, and together with the stabilizing component, the lower edge of the coil frame is fixed, ensuring the safety of the coil frame during hoisting.
[0030] (3) In this invention, a reinforcing plate is set inside the hoisting frame through a reinforcing mechanism, and the reinforcing plate can be tightly attached to the inside of the coil frame. The reinforcing plate further improves the stability of the hoisting frame in fixing the inside of the coil frame, and provides a certain amount of friction. Together with the positioning mechanism and the fastening mechanism, it prevents the coil frame from sliding during the turning process, which would cause wear on the surface of the coil frame.
[0031] (4) In this invention, a balancing mechanism is set up to measure the tilt angle generated by the lifting frame during the movement. When the tilt angle exceeds a certain limit, the tilt angle of the lifting frame is adjusted so that the tilt angle of the lifting frame is always kept within an acceptable range, thereby avoiding large tilt of the lifting frame and deformation of the coil frame caused by the shift of the center of gravity, and improving the safety of the lifting process.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0046] Example 1
[0047] like Figure 1-11 As shown, a coil bobbin processing and lifting device and lifting method are characterized by comprising:
[0048] Positioning mechanism 1, which includes a lifting frame 11 and a positioning component 12 and is used to position and fix the coil frame 001;
[0049] Fastening mechanism 2, which is located below positioning mechanism 1 and is used to fix the lifting frame 11 to the coil frame 001;
[0050] The reinforcing mechanism 3 is located in the middle of the positioning mechanism 1 and is used to further enhance the fixing effect of the fastening mechanism 2;
[0051] The balancing mechanism 4 is located at the positioning mechanism 1 and is used to connect the hoisting cable 432 to the positioning mechanism 1. The balancing mechanism 4 includes a connector 41, multiple sets of measuring components 42 and multiple sets of adjusting components 43. The connector 41 is used to connect the hoisting cable 432 to the positioning mechanism 1. The measuring components 42 and the adjusting components 43 cooperate to adjust the angle of the connector 41 and change the center of gravity of the positioning mechanism 1.
[0052] In this embodiment, by setting the fastening mechanism 2 and the balancing mechanism 4, the coil frame 001 is tightly fixed, ensuring the stability of the coil frame 001 during the hoisting process, preventing wear of the coil frame 001 during hoisting, and ensuring that the center of gravity of the coil frame 001 remains stable during hoisting, avoiding tilting of the coil frame 001 that causes the center of gravity to shift, and preventing deformation or other adverse conditions.
[0053] In detail, the positioning mechanism 1 initially fixes the lifting frame 11 onto the coil frame 001, and the fastening mechanism 2 fixes the coil frame 001 to the lifting frame 11 to ensure that the coil frame 001 is firmly fixed on the lifting frame 11 and to prevent it from falling. The strengthening structure further stabilizes the coil frame 001. In response to the tilting that occurs when the coil frame 001 is hoisted, the balancing mechanism 4 moves the coil frame 001 to keep the center of gravity of the coil frame 001 stable and to prevent the center of gravity from shifting too much.
[0054] It should be noted that the hoisting cable 432 is fixedly connected to the balancing mechanism 4. When the hoisting equipment and coil frame 001 are lifted and moved, the coil frame 001 is heavy and has a large inertia. Therefore, the hoisting equipment and coil frame 001 will tilt as a whole, causing the center of gravity of the coil frame 001 to shift. This will cause the pressure on the lower part of the coil frame 001 to be different, which may cause the coil frame 001 to deform.
[0055] It is worth mentioning that the balancing mechanism 4 can change the tilt angle of the coil frame 001, and control the tilt angle of the coil frame 001 within a small range.
[0056] Furthermore, the positioning element 12 is provided in multiple sets and arrayed on the upper end of the lifting frame 11, including a contact plate 121 vertically slidably connected to the upper end of the lifting frame 11, side plates 122 provided on both sides of the contact plate 121 and intersecting on the lifting frame 11, a rack 123 fixed to the upper end of the contact plate 121 and provided with teeth on both sides, a first gear 124 meshing with the rack 123 and rotatably connected to the lifting frame 11, and a transmission belt 125 connecting the rotation shaft of the first gear 124 and the hinge shaft of the side plate 122.
[0057] In this embodiment, by setting the contact plate 121 and the side plate 122, the lifting frame 11 and the coil frame 001 can maintain a fixed position when the lifting frame 11 is lowered. The side plates 122 on both sides of the multiple positioning members 12 clamp the upper edge of the coil frame 001, so that the lifting frame 11 is located in the middle position of the coil frame 001, which facilitates the subsequent steps.
[0058] In detail, the lifting frame 11 moves down, the contact plate 121 contacts the upper edge of the coil frame 001, the contact plate 121 stops moving, the lifting frame 11 continues to move down, the rack 123 drives the first gear 124 to rotate, the first gear 124 drives the transmission belt 125 to rotate, the transmission belt 125 drives the side plate 122 to rotate, and the side plates 122 on both sides rotate downwards at the same time, clamping the upper edge of the coil frame 001.
[0059] It should be noted that the surfaces of the contact plate 121 and the side plate 122 that need to contact the coil frame 001 are made of rubber or similar materials to avoid wear on the coil frame 001 caused by the contact plate 121 and the side plate 122.
[0060] It is worth mentioning that since the lifting frame 11 needs to fall from above the coil frame 001 onto the coil frame 001, there may be a positional deviation, which may prevent the lifting frame 11 from being exactly in the middle of the coil frame 001, affecting the subsequent fixation. By clamping the coil frame 001 with the side plate 122, the lifting frame 11 can gradually move to the middle position of the coil frame 001.
[0061] Furthermore, the fastening mechanism 2 includes a fixing component 21, a control component 22, and a stabilizing component 23. The fixing component 21 includes multiple sets of support plates 211 arranged below the hoisting frame 11 and whose shape matches the coil frame 001, a moving block 212 hinged to the upper end of the support plate 211, and a first motor 213 whose output shaft is fixedly connected to the hinge shaft of the support plate 211 and fixedly mounted on the moving block 212.
[0062] In this embodiment, by setting a support plate 211 and a moving block 212, the support plate 211 can rotate relative to the moving block 212, so that the support plate 211 can move up or down when the moving block 212 moves, thereby avoiding the sleeper on which the coil frame 001 is placed.
[0063] In detail, when the moving block 212 moves, the first motor 213 drives the support plate 211 to rotate, so that the support plate 211 rotates to above the moving block 212. As the moving block 212 moves to the appropriate position, the first motor 213 drives the support plate 211 to lower, so that the support plate 211 returns to the support position.
[0064] It should be noted that the coil frame 001 is usually placed on two sleepers or a support plate. A gap needs to be left between the coil frame 001 and the object to be placed so that the support plate 211 can move under the coil frame 001, thereby fixing the coil frame 001.
[0065] It is worth mentioning that the material of the contact surface between the support plate 211 and the coil frame 001 should also be made of rubber to avoid wear and tear on the coil frame 001 caused by the support plate 211.
[0066] Furthermore, the control component 22 includes a support rod 221 fixed to the moving block 212 and slidably connected to the hoisting frame 11, a rotating plate 222 rotatably connected to the hoisting frame 11 and having multiple track grooves, a control rod 223 fixed to the support rod 221 and located in the track grooves, and a second motor 224 whose output shaft is fixedly connected to the lower end of the rotating plate 222 and fixedly connected to the hoisting frame 11.
[0067] In this embodiment, by setting the rotating plate 222 and the support rod 221, the moving block 212 is driven in a unified manner, so that the moving block 212 slides outward at the same time, thereby causing the support plate 211 to contact the lower edge of the coil frame 001.
[0068] In detail, the second motor 224 drives the rotating plate 222 to rotate. The rotation of the rotating plate 222 drives the support rod 221 to slide on the hoisting frame 11 through the control rod 223 in the track groove. The support rod 221 drives the moving block 212 to move, thereby fixing the lower end face of the coil frame 001 to the support plate 211.
[0069] Furthermore, the stabilizer 23 is fixedly connected to the outside of the hoisting frame 11 and is arranged in multiple arrays, including a stabilizer block 231 fixedly connected to the lower end of the hoisting frame 11, a clamping plate 232 rotatably connected to the stabilizer block 231, and a third motor 233 whose output shaft is fixedly connected to the rotating shaft of the clamping plate 232.
[0070] In this embodiment, by setting a stabilizing component 23, the clamping plate 232 and the support plate 211 cooperate with each other. The clamping plate 232 shares the weight borne by the support plate 211, thereby improving the safety of the lifting equipment.
[0071] In detail, when the support plate 211 contacts the coil frame 001, the third motor 233 drives the clamping plate 232 to rotate. The clamping plate 232 rotates to the bottom of the support plate 211 and engages with the support plate 211. The clamping plate 232 shares the pressure received by the support plate 211.
[0072] It should be noted that since both the moving block 212 and the support plate 211 are mounted on the support rod 221, the support rod 221 cannot fully support the coil frame 001, and there is a risk that the support rod 221 may break. Therefore, the support plate 211 needs to be reinforced, and the pressure on the support plate 211 is shared by the clamping plate 232.
[0073] It is worth mentioning that the clamping plate 232 in the stabilizer 23 has a certain thickness. During the contact between the clamping plate 232 and the support plate 211, the upper and lower positions of the hoisting frame 11 are more fixed, which prevents the hoisting frame 11 from not descending to the bottom and causing the positioning mechanism 1 above the hoisting frame 11 to not fully clamp the coil frame 001.
[0074] Furthermore, the reinforcing mechanism 3 includes multiple sets of reinforcing plates 31 that are horizontally slidably connected to the middle of the hoisting frame 11, a threaded rod 32 that is rotatably connected to the middle of the hoisting frame 11 and threaded to the lower end of the reinforcing plate 31, a bevel gear 33 that is fixedly connected to the end of the threaded rod 32 away from the reinforcing plate 31, a gear ring 34 that meshes with all the bevel gears 33 and is rotatably connected to the hoisting frame 11, and a fourth motor 35 whose output shaft is fixedly connected to the rotating shaft of the gear ring 34 and fixedly mounted on the hoisting frame 11.
[0075] In this embodiment, by setting the reinforcing plate 31 and the threaded rod 32, the fixing of the coil frame 11 to the coil skeleton 001 is further strengthened. The reinforcing plate 31 is driven by the fourth motor 35 to adhere to the inner wall of the coil skeleton 001, thereby achieving more stable coil fixing. At the same time, it alleviates the situation where the bottom of the coil skeleton 001 is subjected to excessive force when the coil skeleton 001 tilts.
[0076] In detail, the fourth motor 35 starts, drives the gear ring 34 to rotate, the gear ring 34 rotates and drives all the bevel gears 33 to rotate, the bevel gears 33 drive the threaded rod 32 to rotate, the threaded rod 32 drives the reinforcing plate 31 to move, so that the reinforcing plate 31 is tightly attached to the inner wall of the coil frame 001.
[0077] It should be noted that the parts of the reinforcing plate 31 that come into contact with the coil frame 001 are made of materials such as rubber to avoid wear on the coil frame 001 caused by the reinforcing plate 31. At the same time, the rubber and other materials have a large friction force, which further improves the stability of the reinforcing plate 31.
[0078] It is worth mentioning that by using the threaded rod 32 to drive the movement of the reinforcing plate 31, the movement distance of the reinforcing plate 31 is more precise and easier to control, thus avoiding unstable movement of the reinforcing plate 31 and causing wear or even deformation to the inner wall of the coil frame 001.
[0079] Furthermore, the balancing mechanism 4 includes a connector 41, a measuring component 42, and an adjusting component 43. The connector 41 includes a lifting rod 411 for connecting to the lifting cable 432, a universal joint 412 fixedly connected to the lower end of the lifting rod 411, and a balance plate 413 connected to the lower end of the universal joint and used to connect the universal joint 412 and the lifting frame 11.
[0080] In this embodiment, by setting a universal joint 412 and a balance plate 413, the lifting frame 11 can rotate in multiple directions relative to the lifting rod 411, thereby facilitating the adjustment of the lifting frame 11 and ensuring that the lifting frame 11 and the coil frame 001 are always kept within a small tilt angle.
[0081] In detail, when the hoisting frame 11 is lifted, the hoisting equipment and the coil frame 001 will tilt as a whole due to inertia. At this time, the angle of the hoisting frame 11 can be controlled by adjusting the balance plate 413 and the hoisting rod 411, so that the hoisting frame 11 and the coil frame 001 always maintain a small angle of tilt.
[0082] It should be noted that the installation of the universal joint 412 needs to take into account the weight of the coil and the lifting equipment. As the connector 41 between the lifting equipment and the lifting cable 432, the universal joint 412 needs to bear a large weight.
[0083] Furthermore, the measuring element 42 includes
[0084] Inclined tube 421, which is fixedly connected to the balance plate 413 and is inclined, with the outer end of the inclined tube 421 being higher than the inner end of the inclined tube 421;
[0085] Ball bearing 422, which is disposed inside the inclined tube 421 and rolls freely within the inclined tube 421;
[0086] An elastic block 423 is disposed at the outer end of the inclined tube 421. One end of the elastic block 423 extends into the inclined tube 421, and a contact switch is disposed on the outside.
[0087] In this embodiment, by setting the tilt tube 421 and the ball bearing 422, the tilt angle of the hoisting frame 11 is measured. By moving the ball bearing 422 in the tilt tube 421, the tilt angle of the hoisting frame 11 is determined and the adjusting member 43 is triggered, thereby cooperating with the adjusting member 43 to complete the adjustment of the angle of the hoisting frame 11.
[0088] In detail, when the hoisting frame 11 tilts to one side, the tilting tube 421 tilts at the same time. When the tilting angle is greater than the angle between the tilting tube 421 and the horizontal plane, the ball 422 rolls to the outer end of the tilting tube 421. The ball 422 contacts the elastic block 423, causing the elastic block 423 to move and the contact switch on the elastic block 423 to be connected.
[0089] It should be noted that the ball bearing 422 needs to have a certain mass so that when the tilt angle of the lifting frame 11 is not greater than the angle between the tilt tube 421 itself and the horizontal plane, it can stay stably at the inner end of the tilt tube 421. When the tilt angle of the lifting frame 11 is greater than the angle between the tilt tube 421 itself and the horizontal plane, it can quickly roll to the outer end of the tilt tube 421 and trigger the elastic block 423.
[0090] It is worth mentioning that the angle of the tilt tube 421 can be adjusted according to actual needs. The larger the angle of the tilt tube 421, the greater the tilt angle that the equipment can tolerate.
[0091] Furthermore, the adjusting component 43 includes a pulley 431 fixed on the lifting rod 411, a cable 432 with one end fixed on the balance plate 413 and passing through the pulley 431, a coil winding 433 rotatably connected to the balance plate 413 and used for winding the cable 432, and a fifth motor 434 whose output shaft is fixedly connected to the coil winding 433 and controlled by a contact switch on the elastic block 423.
[0092] In this embodiment, by setting up cable 432 and coil loop 433, the relative position of balance plate 413 and lifting rod 411 can be adjusted by coiling cable 432. With the rotation of universal joint, balance plate 413 drives lifting frame 11 to adjust angle.
[0093] In detail, when the contact switch of the elastic block 423 is triggered, the fifth motor 434 drives the coil winding 433 to rotate. The coil winding 433 tightens the cable 432, shortening the cable 432 and causing the balance plate 413 to tilt relative to the lifting rod 411. The side of the balance plate 413 moves closer to the lifting rod 411. After adjusting to a certain angle, the contact switch is disconnected, and the balance plate 413 stops moving. At this time, the device remains at a small tilt angle.
[0094] It should be noted that when one of the adjustment components 43 is triggered, the cable 432 on that side is coiled up, while the cable 432 on the other side is in the unwinding state. Therefore, the coil loop 433 is rotatably connected to the balance plate 413 and needs to be properly damped to avoid excessive unwinding when the coil loop 433 is unwinding.
[0095] Example 2
[0096] like Figure 12 As shown, the hoisting steps of the coil frame 001 processing and hoisting equipment are as follows:
[0097] Step 1, positioning step: The hoisting frame 11 moves down, so that the coil frame 001 is surrounded by the hoisting frame 11. The contact plate 121 of the upper section of the hoisting frame 11 contacts the upper end face of the coil frame 001, causing the contact plate 121 to move up, driving the side plate 122 to rotate, clamping the coil frame 001, thus achieving the initial fixation of the coil and the positioning of the hoisting frame 11.
[0098] The lifting frame 11 moves down, the contact plate 121 contacts the upper edge of the coil frame 001, the contact plate 121 stops moving, the lifting frame 11 continues to move down, the rack 123 drives the first gear 124 to rotate, the first gear 124 drives the transmission belt 125 to rotate, the transmission belt 125 drives the side plate 122 to rotate, and the side plates 122 on both sides rotate downwards at the same time, clamping the upper edge of the coil frame 001.
[0099] Step two, the fastening step: the second motor 224 drives the rotating plate 222 to slide the support rod 221 outward. The support plate 211 drives the fixing piece 21 to approach the coil frame 001 and fit tightly against the bottom of the coil frame 001 to fix the coil frame 001. At the same time, the stabilizing piece 23 is activated, and the third motor 233 drives the clamping plate 232 to rotate. The clamping plate 232 engages with the fixing piece 21. The fourth motor 35 in the reinforcing mechanism 3 drives the reinforcing plate 31 to move outward and fit against the inner wall of the coil frame 001 to further fix the coil and ensure the stability of the coil frame 001 during hoisting.
[0100] The second motor 224 drives the rotating plate 222 to rotate. The rotation of the rotating plate 222, via the control rod 223 in the track groove, drives the support rod 221 to slide on the hoisting frame 11. The moving block 212 moves. When the moving block 212 moves, the first motor 213 drives the support plate 211 to rotate, causing the support plate 211 to rotate above the moving block 212. As the moving block 212 moves to the appropriate position, the first motor 213 drives the support plate 211 to lower, returning it to its supporting position. The second motor 224 drives the rotating plate 222 to rotate. The rotation of the rotating plate 222, via the control rod 223 in the track groove, drives the support rod 221 to slide on the hoisting frame 11. The support rod 221 drives the moving block 212 to move, thereby fixing the support plate 211 to the lower end face of the coil frame 001.
[0101] The fourth motor 35 starts, drives the gear ring 34 to rotate, the gear ring 34 rotates and drives all the bevel gears 33 to rotate, the bevel gears 33 drive the threaded rod 32 to rotate, the threaded rod 32 drives the reinforcing plate 31 to move, so that the reinforcing plate 31 is tightly attached to the inner wall of the coil frame 001.
[0102] Step 3, balancing step: The coil frame 001 is lifted along with the lifting equipment. When the coil frame 001 is moved horizontally, it tilts due to inertia. When the tilt angle exceeds a certain limit, the ball bearing 422 in the tilting tube 421 on the tilting side rolls. The ball bearing 422 contacts the elastic block 423, causing the elastic block 423 to move and triggering the contact switch. The fifth motor 434 starts and retracts the cable 432. The cable 432 becomes shorter, causing the balance plate 413 to tilt relative to the lifting rod 411, so that the coil frame 001 returns to a vertical position relative to the horizontal plane. At this time, the ball bearing 422 disengages from the elastic block 423, and the cable 432 stops retracting, thus stabilizing the center of the coil frame 001.
[0103] When the hoisting frame 11 tilts to one side, the tilting tube 421 on that side tilts simultaneously. When the tilt angle is greater than the angle between the tilting tube 421 and the horizontal plane, the ball bearing 422 rolls towards the outer end of the tilting tube 421. The ball bearing 422 contacts the elastic block 423, causing the elastic block 423 to move and the contact switch on the elastic block 423 to connect. The fifth motor 434 drives the coil winding 433 to rotate. The coil winding 433 bundles the cable 432, shortening the cable 432 and causing the balance plate 413 to tilt relative to the lifting rod 411. This side of the balance plate 413 moves closer to the lifting rod 411. After adjusting to a certain angle, the contact switch is disconnected, and the balance plate 413 stops moving. At this time, the device remains at a small tilt angle.

The contact plate (121) of the upper section of the hoisting frame (11) contacts the upper end face of the coil frame (001), so that the contact plate (121) moves up, driving the side plate (122) to rotate, clamping the coil frame (001), thus achieving the initial fixation of the coil frame and the positioning of the hoisting frame (11); Step 2, fastening step: The second motor (224) drives the rotating plate (222) to slide the support rod (221) outward. The support plate (211) drives the fixing piece (21) to approach the coil frame (001) and fit tightly against the bottom of the coil frame (001) to fix the coil frame (001).
