Description

Technical Field

[0001] The present invention relates to the technical field of port spreaders, and particularly to a lifting spreader with intelligent monitoring and control functions. Background Art

[0002] Under the background of global economic integration, the scale of international trade continues to expand. As an important hub connecting domestic and foreign markets, ports undertake the key task of efficient loading, unloading, and transshipment of goods. The steel industry, as an important pillar of the global industrial system, has an increasing demand for the transportation of its products - steel coils. Steel coils are characterized by their large weight, large volume, special shape (usually cylindrical), and easy damage to the surface, which bring many challenges to their loading, unloading, and transportation in the port environment. Traditionally, the transportation of steel coils mostly relies on road and railway transportation. However, with the continuous increase in the volume of international trade, the requirements for transportation efficiency, cost, and safety are becoming increasingly strict. Sea transportation, with its advantages of large transportation volume and low cost, has gradually become the main way for long-distance transportation of steel coils. At the port link, how to quickly, safely, and efficiently unload steel coils from transport vehicles, load them into containers, and then transfer them to ships has become the key factor restricting the efficiency of the entire logistics chain.

[0003] The prior art with the publication number CN118164360A can limit the steel coil during hoisting, confine the steel coil inside the C-shaped hanger, and prevent the steel coil from accidentally slipping out of the C-shaped hanger during hoisting, greatly increasing the safety during hoisting. At the same time, the movement of the locking plate is realized by relying on the gravity of the steel coil, without the need to additionally configure circuits or electrical components, ensuring the safety during hoisting.

[0004] The above prior art realizes the locking of the steel coil by relying on the gravity of the steel coil, but it is suitable for adapting to wide-width steel coils and cannot effectively limit different slightly narrower-width steel coils. When an unbalanced situation occurs, it will cause the spreader to tilt, and even knock open the lock buckle, resulting in a hoisting accident. Therefore, this application proposes a lifting spreader with intelligent monitoring and control functions. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and propose a lifting spreader with intelligent monitoring and control functions.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A lifting sling with intelligent monitoring and control functions, including a C-shaped plate for carrying steel coils, is characterized in that an adjusting groove, a communicating groove and a power groove are arranged in the C-shaped plate from top to bottom and are communicated with each other according to its shape. An adjusting block guided by sliding connection is arranged in the adjusting groove. A connecting buckle is installed at the upper end of the adjusting block. A first adjusting mechanism and a second adjusting mechanism for driving the adjusting block to move are installed in the adjusting groove, the communicating groove and the power groove. A detachable first cover plate is installed at the upper end of the adjusting groove. A control module is installed on the first cover plate. When the steel coil is placed on the C-shaped plate and lifted, it will squeeze the first adjusting mechanism and the second adjusting mechanism. When the C-shaped plate tilts to one side, in cooperation with the first adjusting mechanism and the second adjusting mechanism, it drives the connecting buckle to move. The connecting buckle moves and moves towards the lower end direction of the inclined C-shaped plate, forcing the C-shaped plate to tend to a stable balance state and locking the steel coil by using the first adjusting mechanism and the second adjusting mechanism. At the same time, the control module will detect whether the state of the C-shaped plate is within the set threshold. If it is within the set threshold, the control module does not work. If it is not within the set threshold, the control module alarms.

[0007] Preferably, the first adjusting mechanism includes a first driving rod fixed on the adjusting block. A first power rod is arranged in the adjusting groove and is arranged to cooperate with the first driving rod. The first power rod is located below the adjusting block in the direction away from the first driving rod. The second adjusting mechanism includes a second driving rod fixed on the adjusting block. A second power rod is arranged in the adjusting groove and is arranged to cooperate with the second driving rod. The second power rod is located below the adjusting block in the direction away from the second driving rod. When the steel coil is placed on the C-shaped plate and lifted, it will squeeze the first power rod and the second power rod to move downward. When the C-shaped plate tilts to one side, it drives the first driving rod and the second driving rod that cooperate to move. The first driving rod and the second driving rod will drive the adjusting block and the connecting buckle to move and move towards the lower end direction of the inclined C-shaped plate, forcing the C-shaped plate to tend to a stable balance state and locking the steel coil by using the first power rod and the second power rod.

[0008] Preferably, a detachable first cover plate is installed at the upper end of the adjusting groove. A through groove is provided through the first cover plate. The connecting buckle passes through the through groove.

[0009] Preferably, two guide rods are fixed on the inner wall of the adjusting groove. The guide rods pass through the adjusting block and are slidably connected with it.

[0010] Preferably, the first adjustment mechanism further includes a first adjustment piston cylinder fixed in the adjustment groove. A first adjustment sealing piston is slidably connected in the first adjustment piston cylinder. The first driving rod is fixed on the first adjustment sealing piston. A plurality of first power piston cylinders are fixed in the power groove. The plurality of first power piston cylinders are connected to the first adjustment piston cylinder through a first delivery pipe. A first power sealing piston is slidably connected in the first power piston cylinder. The first power rod is fixed to the upper end of the first power sealing piston. A first spring is fixed between the first power sealing piston and the first power piston cylinder.

[0011] Preferably, the second adjustment mechanism further includes a second adjustment piston cylinder fixed in the adjustment groove. A second adjustment sealing piston is slidably connected in the second adjustment piston cylinder. The second driving rod is fixed on the second adjustment sealing piston. A plurality of second power piston cylinders are fixed in the power groove. The plurality of second power piston cylinders are connected to the second adjustment piston cylinder through a second delivery pipe. A second power sealing piston is slidably connected in the second power piston cylinder. The second power rod is fixed to the upper end of the second power sealing piston. A second spring is fixed between the second power sealing piston and the second power piston cylinder.

[0012] Preferably, the first delivery pipe and the second delivery pipe are arranged to pass through the communication groove.

[0013] Preferably, it further includes a reinforcement locking mechanism for strengthening the locking of the steel coil. The reinforcement locking mechanism includes a pressing piston cylinder fixed in the power groove. A pressing sealing piston is slidably connected in the pressing piston cylinder. A third spring is fixed between the pressing sealing piston and the pressing piston cylinder. The upper end of the pressing sealing piston is fixed with a lifting rod. The C-shaped plate is provided with a chute communicating with the pressing piston cylinder through the front and back. Two seal blocks capable of resetting are slidably connected in the chute. A pressing block capable of abutting against the steel coil is fixed on the seal block.

[0014] Preferably, a short rod is fixed in the chute. Two fourth springs are fixed on the short rod. The fourth springs are fixedly connected to the seal block.

[0015] Preferably, a second cover plate is fixed on the C-shaped plate. A plurality of through holes are provided through the second cover plate. The first power rod, the lifting rod, and the second power rod penetrate through the through holes and are slidably arranged therein.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Automatic balance adjustment: The first adjustment mechanism and the second adjustment mechanism are distributed in an "X" shape on the C-shaped plate. When the steel coil is placed on the C-shaped plate and lifted, according to the different numbers of the first power rod and the second power rod squeezed by the steel coil, the moving distances of the first drive rod and the second drive rod are different, causing the adjustment block and the connecting buckle to move towards the lower end of the C-shaped plate that is inclined, forcing the C-shaped plate to tend to a stable balance state, ensuring the stability of the device during the lifting process and guaranteeing the safety of lifting.

[0017] 2. Adaptive to steel coil size: There is no need for the staff to adjust the positional relationship between the C-shaped plates. After the C-shaped plates pass through the steel coil, according to the situation of the steel coil itself (such as the number of the first power rod and the second power rod squeezed), the device can automatically adapt to steel coils of different sizes, realizing stable lifting, and improving the convenience and versatility of operation.

[0018] 3. Two-way limit locking: When the numbers of the first power rod and the second power rod squeezed are the same, the hydraulic oil squeezed by the first power rod and the second power rod will flow into the first power piston cylinder and the second power piston cylinder, driving the first power rod and the second power rod to move upward, limiting the steel coil from both sides to prevent the steel coil from slipping off the C-shaped plate, enhancing the safety during the lifting process.

[0019] 4. Reinforcement locking function: The lifting rod in the reinforcement locking mechanism is always squeezed, driving the tight-sealing piston to move, squeezing the internal hydraulic oil into the chute, driving the sealing block and the tight-block to move, making the tight-block abut against the inner wall of the steel coil, forming a triangular support for the steel coil, further increasing the support arc of the steel coil, improving the locking effect on the steel coil, and guaranteeing the safety of the lifting work.

[0020] 5. Adapt to steel coils with different inner diameters: Due to the different inner diameters of the steel coil winding drums, the moving distances of the tight-blocks are different, resulting in different downward moving distances of the lifting rods, and correspondingly different downward movements of the first power rod and the second power rod. However, ultimately, the adjustment of the adjustment block can be realized, making the whole device tend to be stable when lifted, ensuring the safety of the lifting work, and being able to meet the lifting requirements of steel coils with different inner diameters.

[0021] In summary, the present invention relies on the gravity of the steel coil and the squeezing of the first power rod and the second power rod to realize the position adjustment of the adjustment block and the connecting buckle, forcing the lifted C-shaped plate to tend to a stable balance state and locking the steel coil, ensuring the stability of the device during the lifting process and guaranteeing the safety of lifting.

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1-7 , a lifting spreader with intelligent monitoring and control function, including a C-shaped plate 1 for carrying steel coils. Inside the C-shaped plate 1, an adjustment groove 29, a communication groove 23, and a power groove 30 that are connected and communicated are provided from top to bottom according to its shape. An adjustment block 28 that is guided is slidably connected in the adjustment groove 29. Two guide rods 11 are fixed on the inner wall of the adjustment groove 29. The guide rods 11 penetrate through the adjustment block 28 and are slidably connected to it. In this way, the adjustment block 28 can be installed integrally with the C-shaped plate 1, and the position of the adjustment block 28 can also be adjusted.

[0026] Among them, a detachable first cover plate 3 is installed at the upper end of the adjustment groove 29. A through groove 10 is provided through the first cover plate 3, and the connecting buckle 2 is arranged through the through groove 10, which can block the adjustment groove 29. Among them, the upper end of the C-shaped plate 1 is provided with a groove, and the first cover plate 3 is installed in the groove and fixed by bolts. At this time, the upper end of the first cover plate 3 is flush with the upper end of the C-shaped plate 1.

[0027] The connecting buckle 2 is installed at the upper end of the adjusting block 28, and the connecting buckle 2 is used to connect with the lifting end of the crane. A first adjusting mechanism and a second adjusting mechanism for driving the adjusting block 28 to move are installed in the adjusting groove 29, the communicating groove 23, and the power groove 30. The first adjusting mechanism includes a first driving rod 15 fixed on the adjusting block 28. A first power rod 5 is provided in the adjusting groove 29 to cooperate with the first driving rod 15. The first power rod 5 is located below the adjusting block 28 in the direction away from the first driving rod 15.

[0028] For a further detailed explanation of the first adjusting mechanism: The first adjusting mechanism further includes a first adjusting piston cylinder 12 fixed in the adjusting groove 29. A first adjusting sealing piston 16 is slidably connected in the first adjusting piston cylinder 12. The first driving rod 15 is fixed on the first adjusting sealing piston 16. A plurality of first power piston cylinders 26 are fixed in the power groove 30, that is, a plurality of first power piston cylinders 26 are connected in communication.

[0029] A plurality of first power piston cylinders 26 are connected to the first adjusting piston cylinder 12 through a first delivery pipe 14. A first power sealing piston 24 is slidably connected in the first power piston cylinder 26. The first power rod 5 is fixed on the upper end of the first power sealing piston 24. A first spring 25 is fixed on the first power sealing piston 24 and the first power piston cylinder 26.

[0030] The second adjusting mechanism includes a second driving rod 21 fixed on the adjusting block 28. A second power rod 7 is provided in the adjusting groove 29 to cooperate with the second driving rod 21. The second power rod 7 is located below the adjusting block 28 in the direction away from the second driving rod 21. The second adjusting mechanism further includes a second adjusting piston cylinder 19 fixed in the adjusting groove 29. A second adjusting sealing piston 20 is slidably connected in the second adjusting piston cylinder 19. The second driving rod 21 is fixed on the second adjusting sealing piston 20. A plurality of second power piston cylinders 34 are fixed in the power groove 30. A plurality of second power piston cylinders 34 are connected to the second adjusting piston cylinder 19 through a second delivery pipe 22, that is, a plurality of second power piston cylinders 34 are connected in communication.

[0031] A second power sealing piston 35 is slidably connected in the second power piston cylinder 34. The second power rod 7 is fixed on the upper end of the second power sealing piston 35. A second spring 36 is fixed on the second power sealing piston 35 and the second power piston cylinder 34.

[0032] The first conveying pipe 14 and the second conveying pipe 22 are arranged through the communication groove 23, and the communication groove 23 provides space for the first conveying pipe 14 and the second conveying pipe 22.

[0033] When the steel coil is placed on the C-shaped plate 1 and lifted, it will squeeze the first adjusting mechanism and the second adjusting mechanism. When the C-shaped plate 1 tilts to one side, the first adjusting mechanism and the second adjusting mechanism cooperate to drive the connecting buckle 2 to move. The connecting buckle 2 moves and moves towards the lower end of the C-shaped plate 1 that tilts, forcing the C-shaped plate 1 to tend to a stable equilibrium state and locking the steel coil by using the first adjusting mechanism and the second adjusting mechanism. At the same time, the control module 39 will detect whether the state of the C-shaped plate 1 is within the set threshold. If it is within the set threshold, the control module 39 does not work. If it is not within the set threshold, the control module 39 will alarm.

[0034] Specifically, the control module 39 includes a controller, a buzzer, a signal transmitter, and a level sensor. The signal transmitter adopts advanced wireless communication technologies such as Wi-Fi, Bluetooth, or ZigBee, etc., and has the advantages of long transmission distance, strong anti-interference ability, stable and reliable data transmission, etc.; during the normal lifting process of the lifting appliance, when the lifting inclination angle of the C-shaped plate 1 is within the safety threshold range set by the level sensor, the inclination angle data measured by the level sensor fluctuates within the normal range. At this time, the level sensor will not send an abnormal signal to the controller, and the control module 39 is in a "standby" state and does not perform any alarm or control operations. This state indicates that the lifting process of the lifting appliance is within the safe and controllable range, and the staff can continue to operate according to the normal process.

[0035] When due to various reasons (such as improper lifting operation, lifting appliance failure, steel coil center of gravity deviation, etc.) the lifting inclination angle of the C-shaped plate 1 exceeds the safety threshold set by the level sensor, the level sensor will immediately detect this abnormal change and quickly and accurately transmit the corresponding abnormal electrical signal to the controller. The level sensor has high sensitivity and fast response ability, and can react instantly when the inclination angle changes slightly, ensuring that abnormal situations can be detected in time.

[0036] After receiving the abnormal signal transmitted by the level sensor, the controller will immediately start the built-in analysis program, quickly process and analyze the received data. By comparing with the preset safety threshold, the controller can accurately judge whether the inclination angle of the lifting appliance has reached a dangerous level. Once it is confirmed that the inclination angle exceeds the safety range, the controller will quickly make a decision and send control instructions to the buzzer and the signal transmitter respectively.

[0037] After receiving the driving signal sent by the controller, the buzzer will immediately emit a loud alarm sound. This alarm sound has a unique frequency and rhythm, which can stand out among various noises at the port operation site and attract the high attention of on-site staff. After hearing the alarm sound, on-site staff will immediately realize that something abnormal has occurred during the lifting process of the spreader, and may realize that the lifting inclination angle of the C-shaped plate 1 is large, posing an unsafe factor, and thus quickly take corresponding measures, such as stopping the lifting operation, checking the connection between the spreader and the steel coil, adjusting the lifting method, etc., to avoid accidents.

[0038] Meanwhile, the signal transmitter will transmit the abnormal state information of the spreader to the crane control room in the form of a wireless signal in real time. After receiving this abnormal signal through a dedicated monitoring device in the control room, the operator will immediately learn about the situation that the lifting inclination angle of the spreader is too large. The operator can stop the continuous operation of the crane in a timely manner according to the received information to prevent serious consequences such as the steel coil slipping and the spreader being damaged due to continued lifting. In addition, the signal transmitter can also transmit other relevant information of the spreader (such as the specific value of the inclination angle, the time when the abnormality occurred, etc.) to the control room, providing detailed data support for subsequent accident analysis and handling.

[0039] In addition to the above alarm and remote reminder functions, the alarm mechanism of the control module 39 also plays an important role in reminding the staff to check the spreader. When the inclination angle is abnormal, it may mean that some components of the spreader are faulty or worn, or there are irregular behaviors during the lifting operation. Through the alarm of the buzzer and the remote reminder of the signal transmitter, the staff can timely realize the need to conduct a comprehensive inspection and maintenance of the spreader to eliminate potential safety hazards and ensure the normal operation of the spreader in subsequent operations.

[0040] To sum up, through the coordinated work of its various components, the control module 39 forms a complete safety monitoring and early warning system. During the lifting process of the spreader, it can monitor the inclination state of the spreader in real time and accurately, and send an alarm signal in a timely manner when an abnormal situation occurs, reminding on-site staff and operators to take corresponding measures, thus effectively ensuring the safety and reliability of the spreader lifting operation and reducing the risk of safety accidents in port operations.

[0041] Specifically, if it is within the threshold set by the horizontal sensor, the control module 39 does not work. If it is not within the threshold set by the horizontal sensor, the horizontal sensor transmits a signal to the controller, and the controller controls the buzzer to alarm, which can remind the staff that the lifting inclination angle of the C-shaped plate 1 is large and unsafe, and also remind the staff to check the spreader. At the same time, it is transmitted to the crane control room through the signal transmitter to remind the operator not to continue the lifting operation.

[0042] Among them, a second cover plate 4 is fixed on the C-shaped plate 1. A plurality of through holes 17 are provided through the second cover plate 4. The first power rod 5, the lifting rod 6, and the second power rod 7 penetrate through the through holes 17 and are slidably arranged therein. Similarly, a groove is provided on the C-shaped plate 1, and the second cover plate 4 is located in the groove to seal the power groove 30. Among them, limiting rings 18 are fixed on the first power rod 5, the lifting rod 6, and the second power rod 7. The limiting rings 18 in the initial state do not contact the bottom of the second cover plate 4.

[0043] Among them, the first power piston cylinder 26 and the second power piston cylinder 34 are symmetrically distributed on both sides of the abutting piston cylinder 31.

[0044] In summary, the first adjusting mechanism and the second adjusting mechanism are distributed in an "X" shape on the C-shaped plate 1.

[0045] When the steel coil is placed on the C-shaped plate 1, it will squeeze the first power rod 5 and the second power rod 7. When the C-shaped plate 1 hoists the steel coil and moves upward, due to the different or same numbers of the steel coil and the first power rod 5 and the second power rod 7, the numbers of the first power rod 5 and the second power rod 7 squeezed by the steel coil when it is hoisted are also different or the same, so that the moving distances of the first driving rod 15 and the second driving rod 21 that are matched are also different or both remain stationary. When the C-shaped plate 1 tilts to one side, the first driving rod 15 and the second driving rod 21 will drive the adjusting block 28 and the connecting buckle 2 to move and move towards the lower end of the C-shaped plate 1 where it tilts, forcing the C-shaped plate 1 to tend to a stable equilibrium state and locking the steel coil by using the first power rod 5 and the second power rod 7.

[0046] It further includes a reinforcement locking mechanism for strengthening the locking of the steel coil. The reinforcement locking mechanism includes an abutting piston cylinder 31 fixed in the power groove 30. An abutting seal piston 32 is slidably connected in the abutting piston cylinder 31. A third spring 33 is fixed on the abutting seal piston 32 and the abutting piston cylinder 31. The upper end of the abutting seal piston 32 is fixed with a lifting rod 6. The C-shaped plate 1 is provided with a sliding groove 9 penetrating through the front and back and communicating with the abutting piston cylinder 31. Two seal blocks 37 capable of resetting are slidably connected in the sliding groove 9. A short rod 27 is fixed in the sliding groove 9. Two fourth springs 38 are fixed on the short rod 27. The fourth springs 38 are fixedly connected with the seal blocks 37. The seal blocks 37 are fixed with abutting blocks 8 capable of abutting against the steel coil.

[0047] In the initial state of the present invention, that is, after the lifting end of the crane is connected to the connecting buckle 2 and the C-shaped plate 1 is hoisted, the whole device is in a horizontal state.

[0048] When lifting and transporting a steel coil into a container, the staff passes the C-shaped plate 1 through the steel coil without adjusting the positional relationship between the C-shaped plates 1. When the C-shaped plate 1 is lifted, the first power rod 5, the lifting rod 6, and the second power rod 7 abut against the inner wall of the steel coil. As the C-shaped plate 1 continues to move upward, due to the gravity of the steel coil, the first power rod 5, the lifting rod 6, and the second power rod 7 will be squeezed and move downward. There may be the same or different numbers of the first power rod 5 and the second power rod 7 being squeezed by the steel coil. Further explanation is as follows: When the number of the first power rod 5 and the second power rod 7 being squeezed is the same, the first power rod 5 will drive the first power sealing piston 24 to move downward. The first power sealing piston 24 squeezes the hydraulic oil and transports it through the first delivery pipe 14 into the first adjustment piston cylinder 12, increasing the hydraulic oil in the first adjustment piston cylinder 12, and then driving the first adjustment sealing piston 16 and the first driving rod 15 to move; The second power rod 7 will drive the second power sealing piston 35 to move downward. The second power sealing piston 35 squeezes the hydraulic oil and transports it through the second delivery pipe 22 into the second adjustment piston cylinder 19, increasing the hydraulic oil in the second adjustment piston cylinder 19, and then driving the second adjustment sealing piston 20 and the second driving rod 21 to move; Since the same number of the first power rod 5 and the second power rod 7 are squeezed, the amount of the hydraulic oil transported is the same, that is to say, the first driving rod 15 and the second driving rod 21 will remain stationary. That is to say, when the steel coil is placed on the C-shaped plate 1 at this time, the whole device will tend to a stable state when lifted, so as to ensure the stability of lifting the steel coil.

[0049] Since the remaining first power rod 5 and second power rod 7 are not squeezed, the hydraulic oil squeezed by the first power rod 5 and the second power rod 7 will flow into the first power piston cylinder 26 and the second power piston cylinder 34 connected to them. In this way, it can drive the first power sealing piston 24 and the second power sealing piston 35 to move upward, and then drive the first power rod 5 and the second power rod 7 to move upward. In this way, the steel coil is limited from both sides. Finally, the limiting ring 18 abuts against the second cover plate 4, and the whole device tends to be stable, and the steel coil can be limited from both sides to prevent it from slipping off the C-shaped plate 1 due to an accident.

[0050] As described above, that is to say, not into the first adjustment piston cylinder 12 and the second adjustment piston cylinder 19.

[0051] When the number of the first power rod 5 and the second power rod 7 being squeezed is different, the amount of the hydraulic oil squeezed into the first adjustment piston cylinder 12 and the second adjustment piston cylinder 19 is different, such as Figure 4As shown in the figure, it is assumed that the steel coil is placed close to the inner side of the C-shaped plate 1. The number of the first power rods 5 being squeezed is large, and the number of the second power rods 7 being squeezed is small. Therefore, more hydraulic oil is delivered into the first adjusting piston cylinder 12, and "less" hydraulic oil is delivered into the second adjusting piston cylinder 19. However, since the other second power rods 7 are not squeezed, when the second power rods 7 are squeezed, the hydraulic oil in the corresponding second power piston cylinders 34 will flow into other second power piston cylinders 34. Since the adjusting block 28 is driven to move, the hydraulic oil in the second adjusting piston cylinder 19 is also driven into other second adjusting piston cylinders 19. Correspondingly, the other second power rods 7 move upward to block the steel coil. In this way, the adjusting block 28 and the connecting buckle 2 move toward the inner side of the C-shaped plate 1. Finally, after being lifted, the whole device tends to be stable, ensuring the safety of lifting and facilitating the placement of the steel coil into the container.

[0052] When the number of the first power rods 5 being squeezed is less than the number of the second power rods 7 being squeezed, the situation is opposite.

[0053] However, during actual lifting construction, the steel coil will be arranged close to the inner side of the C-shaped plate 1.

[0054] In the above, the lifting rod 6 will always be squeezed. The downward pressure of the lifting rod 6 drives the pressing and sealing piston 32 to move, so that the internal hydraulic oil can be squeezed into the chute 9. The increased hydraulic oil in the chute 9 drives the sealing block 37 and the pressing block 8 to move. Finally, the pressing block 8 abuts against the inner wall of the steel coil, thus increasing the supporting arc of the steel coil; the abutment of the pressing block 8 against the steel coil will be feedback to the sealing block 37 and then to the lifting rod 6 through the hydraulic oil. Therefore, the lifting rod 6 and the pressing block 8 will form a triangular support for the steel coil and finally tend to a stable state. This state is feedback to the first power rod 5 and the second power rod 7, so that the downward moving distance of them is controlled according to the downward moving distance of the lifting rod 6.

[0055] Due to the different inner diameters of the steel coil winding drums, the moving distances of the pressing blocks 8 are different, which in turn leads to different downward movements of the lifting rods 6. Correspondingly, the downward movements of the first power rods 5 and the second power rods 7 are also different. But finally, the adjustment of the adjusting block 28 can be realized, making the whole device tend to be stable when lifted and ensuring the safety of the lifting work.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
