Description

Technical Field

[0001] This invention belongs to the field of transfer device technology, and particularly relates to a cable reel transfer device for a cable production line. Background Technology

[0002] In the cable manufacturing industry, cable reels are a core production material, and their transfer efficiency and safety are crucial, directly affecting the continuity of the production line and the quality of cable products. However, existing cable reel transfer methods have many technical bottlenecks, making it difficult to meet the demands of modern cable production for high efficiency, precision, and safety. Specific problems are as follows:

[0003] Traditional manual handling or simple mechanical devices rely heavily on manual adjustment of the cable reel's posture during transport. This not only results in poor positioning accuracy and prolonged loading and unloading times, but also makes the cable reel highly susceptible to damage from impacts during operation. For example, it can cause wear on the outer sheath of the cable reel and even deformation of the internal structure, seriously affecting the quality of the cable reel. Moreover, most of these methods use rigid support structures, which concentrate axial pressure when the cable reels are stacked. Due to insufficient buffering performance, this can easily lead to interlayer compression damage. This is especially true for extra-long and heavy cable reels, where the protective effect of such rigid support structures is unsatisfactory and cannot effectively ensure the safety of the cable reels during stacking.

[0004] The currently used fixed storage chamber is difficult to adapt to the differences in diameter and length of cable reels of different specifications; if the size of the storage unit needs to be adjusted, the machine must be stopped for disassembly and assembly, which greatly affects the production line's flexible production requirements and reduces production efficiency and flexibility.

[0005] Traditional transfer equipment lacks real-time pressure monitoring and positioning feedback functions, making it impossible to dynamically monitor the stress state of cable reels. This leads to serious safety hazards such as stacking imbalance and eccentric load collapse during transfer and stacking, threatening the safety of equipment and operators. Summary of the Invention

[0006] This invention provides a cable reel transfer device for cable production lines, aiming to solve the problems of low loading and unloading efficiency and easy damage, lack of buffer protection, insufficient modular storage, poor clamping stability and low level of intelligence in existing cable reel transfer methods, which make it difficult to meet the high-efficiency, precise and safe requirements of modern cable production.

The surface of the receiving seat is provided with a limiting groove for clamping the axial direction of the cable reel.

[0011] The clamping structure includes a first electric push rod disposed on both sides of each storage cavity of the support frame. The piston rod end of the first electric push rod is connected to a clamping side plate. A flexible clamping layer is provided on the inner side of the clamping side plate. A V-shaped clamping groove is opened on the inner side of the clamping layer. A friction plate is provided on the inner wall of the V-shaped clamping groove. The friction plate is connected to the clamping side plate through a magnetic quick-release interface.

[0012] Preferably, the lifting device includes:

[0013] Two sets of lifting troughs are arranged side by side on the end of the conveyor frame;

[0014] One set of lifting slots is equipped with a ball screw installed through bearings, and the bottom end of the ball screw is connected to the output shaft of the servo motor through a coupling. The other set of lifting slots is equipped with a linear slide rail.

[0015] The ball screw is threaded with a lifting block, and the linear guide rail is slidably fitted with a slider.

[0016] The lifting block and the slider are connected to the same feeding bucket. The upper surface of the feeding bucket is set as an inclined shovel surface along the material conveying direction and is covered with a polyurethane anti-slip layer.

[0017] Preferably, the surface of the feeding bucket is evenly distributed with several vacuum adsorption holes, which are connected to a negative pressure pump via a solenoid valve.

[0018] Preferably, the limiting structure includes:

[0019] A portal frame spanning a supporting frame;

[0020] The top of the portal frame is equipped with a second electric push rod that is set vertically.

[0021] The piston rod end of the second electric actuator is connected to a partition baffle.

[0022] Preferably, buffer pads are provided on both sides of the partition baffle, and a limiting plate is provided on the side of the buffer pad away from the partition baffle. The surface of the limiting plate is coated with a polytetrafluoroethylene anti-adhesion coating.

[0023] Preferably, carbon fiber support rods are provided at the upper part of both ends of the support frame, and the tops of several support rods are connected to an umbrella-shaped baffle plate. The unfolded projected area of ​​the baffle plate is larger than the opening of the stacking cavity.

[0024] Preferably, the pressure-bearing surface of the limiting groove is embedded with a PVDF piezoelectric thin film sensor array, and the surface is coated with a polytetrafluoroethylene anti-corrosion coating.

[0025] Preferably, the magnetic quick-release interface includes an electromagnet disposed on the clamping side plate and a magnetic conductive layer disposed on the back of the friction pad.

[0026] Preferably, a push handle is provided on the side of the conveyor away from the lifting device, and the surface of the push handle is covered with a non-slip silicone layer.

[0027] Preferably, each of the four corner positions at the bottom of the conveyor frame is equipped with a double-spring damping shock-absorbing roller.

[0028] Compared with the prior art, the embodiments of this application have the following main advantages:

[0029] Firstly, this invention utilizes a liftable loading bucket with an inclined shovel surface on the upper end, covered with a polyurethane anti-slip layer. This design facilitates the smooth sliding of the cable reel into the bucket while effectively preventing it from sliding or falling inside. Simultaneously, the negative pressure pump equipped with the device creates a negative pressure environment at the vacuum adsorption hole, tightly adsorbing the cable reel onto the shovel surface of the loading bucket, further enhancing the fixing effect of the cable reel transmission and preventing displacement due to shaking during transmission.

[0030] In addition, the laser positioning sensor integrated into the mobile end of the device can accurately locate the position of the cable reel, thereby assisting the lifting device in accurately placing the cable reel in the designated position.

[0031] Secondly, this device adopts a semi-enclosed stacking chamber design. The buffer layer and strip groove on its inner wall can effectively buffer the impact force generated when the cable roll is placed, thus protecting the cable roll. The device is equipped with multiple limiting structures, which divide the stacking chamber into multiple independent storage chambers. In each independent storage chamber, the hydraulic cylinder can push the receiving seat to achieve axial limiting support for the cable roll, ensuring the stability of the cable roll position. In addition, in terms of fixing the cable roll, the clamping side plate can firmly clamp the cable roll to prevent it from shaking or shifting during transportation.

[0032] Thirdly, this device enables the separation and elimination of storage chambers to meet different storage needs, demonstrating the safety, intelligence, and flexible adaptability of storage. The buffer pads on both sides of the partition baffle absorb and buffer the impact force, preventing the cable roll from rigidly colliding with the partition baffle; the limiting plate further limits and constrains to prevent excessive displacement; the PTFE anti-adhesion coating reduces the adhesion between the cable roll and the limiting plate, ensuring smooth movement or removal of the cable roll. In addition, the protective structure on the support frame, through the baffle with an unfolded area larger than the opening of the stacking chamber, completely covers the stacking chamber, effectively protecting the cable roll from the effects of severe weather, ensuring the quality stability of the cable roll during transportation and storage, and ensuring the efficient and stable operation of the entire transportation device.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] This invention provides a cable reel transfer device for a cable production line, such as... Figure 1-8 As shown, it includes:

[0045] The loading and unloading structure includes a conveyor frame 1, which has a lifting device on the side facing the cable reel conveying direction. The moving end of the lifting device integrates a laser positioning sensor 2.

[0046] The buffer support structure includes vertical support frames 3 symmetrically arranged on both sides of the conveyor frame 1. The support frames 3 enclose a semi-enclosed stacking cavity. The inner wall of the support frames 3 is covered with a polyurethane-rubber composite buffer layer 4. The surface of the buffer layer 4 is provided with strip grooves.

[0047] The modular stacking structure includes multiple limiting structures arranged in parallel within the stacking cavity. The limiting structures divide the stacking cavity into several independent storage cavities. Each storage cavity has a sunken assembly groove 5 at the bottom corresponding to the conveyor frame 1. A set of vertically arranged hydraulic cylinders 6 are symmetrically distributed in the assembly groove 5. The piston rods of the two hydraulic cylinders 6 are connected to the same receiving seat 7. The surface of the receiving seat 7 is provided with a limiting groove 8 for clamping the axial direction of the cable reel.

[0048] The clamping structure includes a first electric push rod 9 disposed on both sides of each storage cavity of the support frame 3. The piston rod end of the first electric push rod 9 is connected to a clamping side plate 10. A flexible clamping layer 11 is provided on the inner side of the clamping side plate 10. A V-shaped clamping groove is opened on the inner side of the clamping layer 11. A friction plate 12 is provided on the inner wall of the V-shaped clamping groove. The friction plate 12 is connected to the clamping side plate 10 through a magnetic quick-release interface.

[0049] It should be noted that existing cable reel transfer methods suffer from drawbacks such as low loading and unloading efficiency, susceptibility to damage, lack of buffering and protection, insufficient modular storage, poor clamping stability, and low level of intelligence, making it difficult to meet the high-efficiency, precise, and safe requirements of modern cable production. This solution addresses these issues by using a liftable loading bucket 19 with an inclined shovel surface covered with a polyurethane anti-slip layer. This facilitates the cable reel's sliding into the bucket while effectively preventing it from sliding or falling inside. Combined with a negative pressure pump 21, a negative pressure environment is created at the vacuum suction hole 20, tightly adhering the cable reel to the shovel surface, enhancing the transmission and fixing effect, and preventing displacement due to shaking during transmission. Regarding positioning, the buffer layer 4 and the strip groove on the inner wall of the semi-enclosed stacking cavity effectively buffer the impact force during cable reel placement, providing protection. The device functions as follows: multiple limiting structures divide the stacking cavity into independent storage cavities; hydraulic cylinder 6 pushes the receiving seat 7 to achieve axial limiting support; clamping side plate 10 firmly clamps the cable roll to prevent shaking and displacement during transportation; the device also has the ability to flexibly adjust the storage space, and can realize the separation and cancellation of storage cavities to meet different storage needs; buffer pads 25 on both sides of the dividing baffle 24 absorb impact force to avoid rigid collisions; limiting plate 26 prevents excessive displacement; polytetrafluoroethylene anti-adhesion coating reduces adhesion to ensure smooth movement or removal of the cable roll; the protective structure on the support frame 3 completely covers the stacking cavity through the shielding plate 28, effectively protecting the cable roll from the effects of severe weather, ensuring the quality stability of the cable roll during transportation and storage, and ensuring the efficient and stable operation of the entire transportation device.

[0050] Specifically, in this embodiment, during the loading and unloading stage, the lifting device on the side of the conveyor frame 1 facing the direction of cable roll conveying is started and operated; the laser positioning sensor (LMS5IP67) integrated in the moving end of the lifting device will accurately locate the position of the cable roll, thereby assisting the lifting device to complete the loading and unloading operation of the cable roll, accurately placing the cable roll in the designated position, and greatly improving the convenience of loading and unloading.

[0051] Subsequently, the cable roll enters the stacking area; the vertical support frames 3 symmetrically arranged on both sides of the conveyor frame 1 enclose a semi-enclosed stacking cavity. The buffer layer 4 and the strip groove covering the inner wall of the support frame 3 can effectively buffer the impact force generated when the cable roll is placed, and play a protective role for the cable roll.

[0052] Multiple limiting structures divide the stacking cavity into several independent storage cavities; at the bottom of each storage cavity, a sunken assembly groove 5 is opened at the corresponding position of the conveyor frame 1, and a set of vertical hydraulic cylinders 6 are symmetrically distributed in the groove; when the hydraulic cylinder 6 is started, its piston rod pushes the receiving seat 7 to rise or fall, so that the cable roll can move smoothly into the limiting groove 8 on the surface of the receiving seat 7, thereby realizing the axial limiting support of the cable roll and ensuring the stability of the cable roll in the storage cavity;

[0053] Finally, the clamping structure secures the cable roll; the first electric push rod 9, which is set on both sides of each storage cavity of the support frame 3, starts to move, and the piston rod pushes the clamping side plate 10 closer to the cable roll. The flexible clamping layer 11 on the inner side of the clamping side plate 10 tightly adheres to the cable roll; the inner wall of the V-shaped clamping groove on the inner side of the clamping layer 11 is connected to a friction plate 12 through a magnetic quick-release interface. The friction plate 12 can increase the friction with the cable roll, thereby firmly clamping the cable roll and ensuring that the cable roll remains stable during transportation, avoiding shaking and displacement.

[0054] In a further preferred embodiment of the present invention, such as Figure 1-5 As shown, the lifting device includes:

[0055] Two sets of lifting grooves 13 are arranged side by side on one end of the conveyor frame 1;

[0056] One set of lifting grooves 13 is equipped with a ball screw 14 installed in the bearing, and the bottom end of the ball screw 14 is connected to the output shaft of the servo motor 15 through a coupling. The other set of lifting grooves 13 is equipped with a linear slide rail 16.

[0057] The ball screw 14 is threaded with a lifting block 17, and the linear slide rail 16 is slidably fitted with a slider 18.

[0058] The lifting block 17 and the slider 18 are connected to the same feeding bucket 19 on their outer sides. The upper end face of the feeding bucket 19 is set as an inclined shovel surface along the material conveying direction, and the surface is covered with a polyurethane anti-slip layer.

[0059] In this embodiment, the servo motor 15 starts, and its output shaft drives the ball screw 14 in a set of lifting grooves 13 connected to it to rotate through a coupling. Since the ball screw 14 is threaded with a lifting block 17, as the ball screw 14 rotates, the lifting block 17 will move up or down along the axial direction of the ball screw 14. At the same time, in another set of lifting grooves 13, there is a linear slide rail 16, and the slider 18 slides on the linear slide rail 16. The lifting block 17 and the slider 18 are connected to the same loading bucket 19. In this way, under the drive of the lifting block 17, the slider 18 will also slide synchronously along the linear slide rail 16, thereby ensuring that the loading bucket 19 can rise or fall smoothly. The upper end face of the loading bucket 19 is set with an inclined shovel surface along the material conveying direction. This design facilitates the smooth sliding of the cable roll into the bucket, and the polyurethane anti-slip layer covering its surface can increase the friction between it and the cable roll, preventing the cable roll from sliding or falling in the bucket, thereby realizing the stable lifting and transportation of the cable roll.

[0060] In a further preferred embodiment of the present invention, such as Figure 6 As shown, the surface of the feeding bucket 19 is evenly distributed with several vacuum adsorption holes 20, and the vacuum adsorption holes 20 are connected to the negative pressure pump 21 through a solenoid valve.

[0061] In this embodiment, the negative pressure pump 21 starts working, creating a negative pressure environment at the vacuum adsorption hole 20, which tightly adsorbs the cable roll onto the shovel surface of the feeding bucket 19, enhancing the fixing effect of the cable roll on the feeding bucket 19 and preventing it from shifting or falling off due to shaking during transmission.

[0062] In a further preferred embodiment of the present invention, such as Figure 5-7 As shown, the limiting structure includes:

[0063] A portal frame 22 spanning across the support frame 3;

[0064] The top of the portal frame 22 is provided with a second electric push rod 23 arranged in the vertical direction;

[0065] The piston rod end of the second electric push rod 23 is connected to a partition baffle 24.

[0066] In this embodiment, the piston rod of the second electric push rod 23 extends downward, driving the partition baffle 24 connected to its end to move downward. The partition baffle 24 gradually descends to a suitable position, dividing the stacking cavity into several independent storage cavities, thereby limiting and separating the storage location of the cable rolls and avoiding interference between different cable rolls. When it is necessary to adjust the size of the storage cavity or remove the cable roll, the piston rod of the second electric push rod 23 retracts upward, driving the partition baffle 24 to move upward, thereby canceling the separation state of the stacking cavity so as to perform the corresponding operation.

[0067] In a further preferred embodiment of the present invention, such as Figure 5 As shown, buffer pads 25 are provided on both sides of the partition baffle 24, and a limiting plate 26 is provided on the side of the buffer pad 25 away from the partition baffle 24. The surface of the limiting plate 26 is coated with a polytetrafluoroethylene anti-adhesion coating.

[0068] In this embodiment, when the partition baffle 24 moves to a suitable position to limit the cable roll, the buffer pads 25 provided on both sides of the partition baffle 24 play a role. When the cable roll comes into contact with the partition baffle 24 due to shaking or other external forces during the transfer process, the buffer pads 25 can effectively absorb and buffer the impact force, avoiding direct rigid collision between the cable roll and the partition baffle 24, thereby protecting the cable roll. At the same time, the limiting plate 26 provided on the side of the buffer pad 25 away from the partition baffle 24 further limits and constrains the cable roll, preventing the cable roll from excessive displacement in the separated storage cavity. The polytetrafluoroethylene anti-adhesion coating on the surface of the limiting plate 26 can effectively reduce the adhesion between the cable roll and the limiting plate 26, preventing the cable roll from sticking to the limiting plate 26 during placement or removal, ensuring that the cable roll can move smoothly in the storage cavity or be removed, and ensuring the high efficiency and stability of the entire transfer device.

[0069] In a further preferred embodiment of the present invention, such as Figure 1-3 As shown, carbon fiber support rods 27 are provided at the upper part of both ends of the support frame 3. The tops of several support rods 27 are connected to an umbrella-shaped baffle 28. The projected area of ​​the baffle 28 when unfolded is larger than the opening of the stacking cavity.

[0070] In this embodiment, since the projected area of ​​the shield 28 after being unfolded is larger than the opening of the stacking cavity, the unfolded shield 28 can completely cover the stacking cavity, providing effective protection for the cable roll inside the stacking cavity, preventing rainwater from wetting the cable roll and causing it to become damp and damaged, or preventing the cable roll from being exposed to sunlight for a long time, causing the surface temperature of the cable roll to be too high and accelerating aging, thereby ensuring the quality stability of the cable roll during transportation and storage.

[0071] In a further preferred embodiment of the present invention, such as Figure 3 As shown, the pressure-bearing surface of the limiting groove 8 is embedded with a PVDF piezoelectric thin film sensor 29 array, and the surface is coated with a polytetrafluoroethylene anti-corrosion coating.

[0072] In this embodiment, when the cable reel is placed into the limiting groove 8 of the receiving seat 7, the limiting groove 8 provides axial support for the cable reel. The PVDF piezoelectric film sensor 29 (LDT0-028K) array embedded in the pressure-bearing surface of the limiting groove 8 begins to function. Due to the piezoelectric effect of the PVDF piezoelectric film, when the cable reel applies pressure to the pressure-bearing surface of the limiting groove 8, the sensor array converts the pressure signal into an electrical signal output. By collecting and analyzing these electrical signals, the magnitude and distribution of pressure exerted by the cable reel on the limiting groove 8 can be monitored in real time, thereby understanding the placement status and weight distribution of the cable reel, providing data support for the stable operation and safety of the device. At the same time, the polytetrafluoroethylene anti-corrosion coating on the surface of the limiting groove 8 can effectively isolate corrosive substances in the external environment, such as humid air and chemical gases, preventing corrosion of the surface of the limiting groove 8, extending the service life of the limiting groove 8, ensuring that it always maintains good limiting performance and pressure bearing capacity, and ensuring the stable storage of the cable reel during transportation.

[0073] In a further preferred embodiment of the present invention, such as Figure 7 As shown, the magnetic quick-release interface includes an electromagnet located on the clamping side plate 10 and a magnetic conductive layer located on the back of the friction plate 12.

[0074] In this embodiment, when it is necessary to install the friction plate 12 to enhance the clamping effect on the cable roll, the electromagnet provided on the clamping side plate 10 is energized, and the electromagnet generates magnetism. Since the back of the friction plate 12 is provided with a magnetic conductive layer, under the attraction of the electromagnet's magnetic force, the friction plate 12 will quickly and accurately adhere to the clamping side plate 10, achieving rapid installation and fixation. This ensures that the inner wall of the V-shaped clamping groove on the inner side of the clamping side plate 10 can increase the friction with the cable roll through the friction plate 12, firmly clamping the cable roll.

[0075] In a further preferred embodiment of the present invention, such as Figure 2 As shown, the conveyor frame 1 is provided with a push handle 30 on the side away from the lifting device, and the surface of the push handle 30 is covered with an anti-slip silicone layer 31.

[0076] In this embodiment, when the entire transfer device needs to be pushed, the operator can hold the push handle 30 and apply pushing force. The anti-slip silicone layer 31 covering the surface of the push handle 30 can significantly increase the friction between the operator's hand and the handle, effectively preventing the handle from slipping out of the hand due to sweaty hands or uneven force during the pushing process, ensuring that the operator can push the device to the designated position stably and safely, and improving the reliability and convenience of operation.

[0077] In a further preferred embodiment of the present invention, such as Figure 1-3 As shown, each of the four corner positions at the bottom of the conveyor frame 1 is equipped with a double-spring damping shock-absorbing roller 32.

[0078] In this embodiment, when the device is moving, such as when it passes over uneven ground, encounters bumpy roads or steps, the double-spring damping shock-absorbing roller 32 can effectively buffer the impact force from the ground, so that the roller can smoothly transition and avoid continuous shaking of the device after buffering.

[0079] Working principle: When using this invention, the operator holds the push handle 30 located on the side of the conveyor frame 1 away from the lifting device and applies a pushing force to ensure that the device can be pushed stably and safely to the loading and unloading area;

[0080] Upon arrival at the loading and unloading area, loading and unloading operations commence. The lifting device on the side of the conveyor frame 1 facing the direction of cable reel transport is activated, and the servo motor 15 starts. Its output shaft drives the ball screw 14 in a set of lifting grooves 13 connected to it to rotate via a coupling. Since the ball screw 14 is threaded with a lifting block 17, as the ball screw 14 rotates, the lifting block 17 will move up or down along the axial direction of the ball screw 14. At the same time, in another set of lifting grooves 13, a linear slide rail 16 is provided, and the slider 18 moves along the linear slide rail. The lifting block 17 and the slider 18 are connected to the same feeding bucket 19 on the outside of the rail 16. In this way, the slider 18 will also slide synchronously along the linear slide rail 16 under the drive of the lifting block 17, thereby ensuring that the feeding bucket 19 can rise or fall smoothly. The upper end face of the feeding bucket 19 is set with an inclined shovel surface along the material conveying direction. This design makes it easy for the cable roll to slide smoothly into the bucket, and the polyurethane anti-slip layer covering its surface can increase the friction between it and the cable roll, preventing the cable roll from sliding or falling in the bucket.

[0081] When the cable roll is inside the feeding bucket 19, the negative pressure pump 21 starts to work, creating a negative pressure environment at the vacuum adsorption hole 20, which tightly adsorbs the cable roll onto the shovel surface of the feeding bucket 19, enhancing the fixing effect of the cable roll on the feeding bucket 19 and preventing it from shifting or falling off due to shaking during transmission.

[0082] The laser positioning sensor 2 integrated in its mobile terminal can accurately locate the position of the cable roll, thereby assisting the lifting device in completing the loading and unloading of the cable roll, accurately placing the cable roll in the designated position, and greatly improving the convenience of loading and unloading.

[0083] Next, the cable roll enters the stacking area; the vertical support frames 3 symmetrically arranged on both sides of the conveyor frame 1 enclose a semi-enclosed stacking cavity. The inner wall of the support frame 3 is covered with a buffer layer 4 and a strip groove, which can effectively buffer the impact force generated when the cable roll is placed and protect the cable roll.

[0084] Inside the stacking chamber, multiple limiting structures divide the chamber into several independent storage chambers. At the bottom of each storage chamber, a sunken assembly groove 5 is provided at the corresponding position of the conveyor frame 1. A set of vertical hydraulic cylinders 6 are symmetrically distributed in the groove. When the hydraulic cylinder 6 is activated, its piston rod pushes the receiving seat 7 to rise or fall, so that the cable roll can move smoothly into the limiting groove 8 on the surface of the receiving seat 7, thereby achieving axial limiting support for the cable roll and ensuring the stability of the cable roll in the storage chamber.

[0085] Meanwhile, the PVDF piezoelectric film sensor array embedded in the pressure-bearing surface of the limiting groove 8 begins to function. Due to the piezoelectric effect of the PVDF piezoelectric film, when the cable roll applies pressure to the pressure-bearing surface of the limiting groove 8, the sensor array converts the pressure signal into an electrical signal output. By collecting and analyzing these electrical signals, the magnitude and distribution of pressure exerted by the cable roll on the limiting groove 8 can be monitored in real time, thereby understanding the placement status and weight distribution of the cable roll, providing data support for the stable operation and safety of the device. At the same time, the polytetrafluoroethylene anti-corrosion coating on the surface of the limiting groove 8 can effectively isolate corrosive substances in the external environment, such as humid air and chemical gases, preventing the surface of the limiting groove 8 from being corroded, extending the service life of the limiting groove 8, ensuring that it always maintains good limiting performance and pressure-bearing capacity, and ensuring the stable storage of the cable roll during transportation.

[0086] After the cable roll enters the storage cavity and completes its initial positioning, the clamping structure fixes the cable roll in place. The first electric push rod 9, which is set on both sides of each storage cavity, starts to move. The piston rod pushes the clamping side plate 10 closer to the cable roll. The flexible clamping layer 11 on the inner side of the clamping side plate 10 tightly adheres to the cable roll. The inner wall of the V-shaped clamping groove on the inner side of the clamping layer 11 is connected to a friction plate 12 through a magnetic quick-release interface. The friction plate 12 can increase the friction with the cable roll, thereby firmly clamping the cable roll and ensuring that the cable roll remains stable during transportation, avoiding shaking and displacement.

[0087] During the transfer process, the stacking cavity can be divided and adjusted as needed; the piston rod of the second electric push rod 23 begins to extend downward, driving the dividing baffle 24 connected to its end to move downward. The dividing baffle 24 gradually descends to a suitable position, dividing the stacking cavity into several independent storage cavities, thereby limiting and separating the storage location of the cable rolls and avoiding interference between different cable rolls; when it is necessary to adjust the size of the storage cavity or remove the cable roll, the piston rod of the second electric push rod 23 retracts upward, driving the dividing baffle 24 to move upward, thereby canceling the separation state of the stacking cavity so as to carry out the corresponding operation;

[0088] When the partition baffle 24 moves to the appropriate position to limit the cable roll, the buffer pads 25 set on both sides of the partition baffle 24 play a role. When the cable roll comes into contact with the partition baffle 24 due to shaking or other external forces during the transfer process, the buffer pads 25 can effectively absorb and buffer the impact force, avoiding direct rigid collision between the cable roll and the partition baffle 24, thus protecting the cable roll. At the same time, the limiting plate 26 set on the side of the buffer pad 25 away from the partition baffle 24 further limits and constrains the cable roll, preventing the cable roll from excessive displacement in the separated storage cavity. The polytetrafluoroethylene anti-adhesion coating on the surface of the limiting plate 26 can effectively reduce the adhesion between the cable roll and the limiting plate 26, preventing the cable roll from sticking to the limiting plate 26 during placement or removal, ensuring that the cable roll can move smoothly in the storage cavity or be removed, and ensuring the high efficiency and stability of the entire transfer device.

[0089] In addition, during transportation and storage, a protective structure is provided on the support frame 3 to protect the cable rolls from severe weather. Since the projected area of ​​the shield 28 after it is unfolded is larger than the opening of the stacking cavity, the unfolded shield 28 can completely cover the stacking cavity, providing effective protection for the cable rolls inside the stacking cavity. This prevents rainwater from wetting the cable rolls and causing them to become damp and damaged, or prevents prolonged exposure to sunlight from causing the surface temperature of the cable rolls to become too high and accelerating aging, thereby ensuring the quality stability of the cable rolls during transportation and storage.
