Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of port lifting devices, and particularly relates to a hoist with intelligent monitoring and control functions. BACKGROUND

[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 bear the key task of efficient loading and unloading and transportation 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 large weight, large volume, special shape (usually cylindrical), and easily damaged surface, which poses many challenges to their loading, unloading, and transportation in port environments. Traditionally, steel coil transportation relies on road and rail transportation, but as international trade volume continues to rise, the requirements for transportation efficiency, cost, and safety are becoming increasingly stringent. Sea transportation, with its large capacity and low cost, has gradually become the main mode of long-distance transportation of steel coils. In the port link, how to quickly, safely, and efficiently unload steel coils from transport vehicles and load them into containers for further transportation to ships has become a key factor restricting the efficiency of the entire logistics chain.

[0003] The prior art with publication number CN118164360A can limit the steel coil during hoisting, restrict the steel coil inside the C-shaped lifting bracket, prevent the steel coil from escaping from the C-shaped lifting bracket during hoisting due to accidents, greatly increase the safety during hoisting, and rely on the gravity of the steel coil to move the locking plate, without the need for additional circuit or electrical elements, ensuring safety during hoisting.

When the steel coil is placed on the C-shaped plate and lifted, according to the number of the first power rod and the second power rod pressed by the steel coil, the first driving rod and the second driving rod move different distances, so that the adjusting block and the connecting buckle move to the low end of the C-shaped plate, forcing the C-shaped plate to tend to a stable balance state, ensuring the stability of the device during lifting, and ensuring the safety of lifting.

[0022] 5.

[0023] In summary, the present application relies on the gravity of the steel coil and the pressing of the first power rod and the second power rod to realize the position adjustment of the adjusting 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 lifting, and ensuring the safety of lifting.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0033] REFERENCE Figures 1-7 A lifting sling with intelligent monitoring control function comprises a C-shaped plate 1 for bearing a steel coil, and the C-shaped plate 1 is provided with an adjusting groove 29, a communication groove 23 and a power groove 30 in sequence from top to bottom according to the shape of the C-shaped plate 1.

[0035] The upper end of the adjusting block 28 is provided with the connecting buckle 2, which is connected with the lifting end of the crane. The adjusting groove 29, the communication groove 23 and the power groove 30 are provided with first and second adjusting mechanisms for driving the adjusting block 28 to move.

The first power rod 5 is located below the adjusting block 28 in the direction away from the first driving rod 15.

[0036] The first adjusting mechanism is further explained in detail. The first adjusting mechanism further includes a first adjusting piston cylinder 12 fixed in the adjusting groove 29. The first adjusting piston cylinder 12 is slidably connected with a first adjusting sealing piston 16. 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, the plurality of first power piston cylinders 26 are connected in communication.

[0037] The plurality of first power piston cylinders 26 are connected with the first adjusting piston cylinder 12 through a first conveying pipe 14. The first power piston cylinder 26 is slidably connected with a first power sealing piston 24. The first power rod 5 is fixed on the upper end of the first power sealing piston 24. The first power sealing piston 24 is fixed with a first spring 25 on the first power piston cylinder 26.

[0038] The second adjusting mechanism includes a second driving rod 21 fixed on the adjusting block 28. The adjusting groove 29 is provided with a second power rod 7 matched 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. The second adjusting piston cylinder 19 is slidably connected with a second adjusting sealing piston 20. 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. The plurality of second power piston cylinders 34 are connected with the second adjusting piston cylinder 19 through a second conveying pipe 22, that is, the plurality of second power piston cylinders 34 are connected in communication.

[0039] The second power piston cylinder 34 is slidably connected with a second power sealing piston 35. The second power rod 7 is fixed on the upper end of the second power sealing piston 35. The second power sealing piston 35 is fixed with a second spring 36 on the second power piston cylinder 34.

[0040] The first conveying pipe 14 and the second conveying pipe 22 pass through the communication groove 23, and the communication groove 23 provides space for the first conveying pipe 14 and the second conveying pipe 22.

[0041] When the steel coil is placed on the C-shaped plate 1 and hoisted, the first adjusting mechanism and the second adjusting mechanism are pressed, and when the C-shaped plate 1 tilts to one side, the first adjusting mechanism and the second adjusting mechanism drive the connecting buckle 2 to move, the connecting buckle 2 moves and moves to the low end of the C-shaped plate 1, forcing the C-shaped plate 1 to tend to be in a stable equilibrium state and locked by the first adjusting mechanism and the second adjusting mechanism, and at the same time, the control module 39 detects whether the state of the C-shaped plate 1 is within the set threshold value, if it is within the set threshold value, the control module 39 does not work, and if it is not within the set threshold value, the control module 39 alarms.

[0042] Specifically, the control module 39 includes a controller, a buzzer, a signal transmitter and a level sensor, the signal transmitter adopts advanced wireless communication technology such as Wi-Fi, Bluetooth or ZigBee, 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 value set by the level sensor, the inclination angle data measured by the level sensor is within the normal fluctuation 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 operation. This state indicates that the lifting process of the lifting appliance is within a safe and controllable range, and the workers can continue to work according to the normal process.

[0043] When the lifting inclination angle of the C-shaped plate 1 exceeds the safety threshold value set by the level sensor due to various reasons such as improper lifting operation, lifting appliance failure, steel coil center of gravity deviation, etc., 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 capability, and can react instantly when the inclination angle changes slightly, ensuring that abnormal conditions can be discovered in time.

[0044] After receiving the abnormal signal transmitted by the level sensor, the controller will immediately start the built-in analysis program to quickly process and analyze the received data. By comparing with the preset safety threshold value, 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.

[0045] The buzzer will immediately emit a loud alarm sound after receiving the driving signal sent by the controller. This alarm sound has a unique frequency and rhythm, which can stand out among the various noises in the port operation site and attract the attention of the site workers. When the site workers hear the alarm sound, they will immediately realize that there is an abnormal situation during the lifting of the spreader, and may realize that the C-shaped plate 1 has a large lifting inclination angle, which is not safe, and thus take appropriate 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.

[0046] At the same time, the signal transmitter will transmit the abnormal state information of the spreader to the crane control room in the form of wireless signals. When the control personnel receive this abnormal signal through the special monitoring equipment in the control room, they will immediately understand the situation of the large lifting inclination angle of the spreader. The control personnel can stop the continuous control of the crane in time according to the received information, to prevent serious consequences such as steel coil sliding and spreader damage caused by continuous lifting. In addition, the signal transmitter can also transmit other related information of the spreader (such as the specific value of the inclination angle, the time of the abnormality, etc.) to the control room, providing detailed data support for subsequent accident analysis and handling.

[0047] In addition to the above-mentioned alarm and remote reminder functions, the alarm mechanism of the control module 39 also plays an important role in reminding the workers to check the spreader. When the inclination angle is abnormal, it may mean that some parts of the spreader are faulty or worn out, or there are non-standard behaviors in the lifting operation process. Through the alarm of the buzzer and the remote reminder of the signal transmitter, the workers can realize in time that the spreader needs to be checked and maintained comprehensively to eliminate potential safety hazards and ensure the normal operation of the spreader in subsequent operations.

[0048] In summary, the control module 39 forms a perfect safety monitoring and early warning system through the coordinated work of its various components. During the lifting of the spreader, it can monitor the inclination state of the spreader in real time and accurately, and send an alarm signal in time when an abnormal situation occurs, reminding the site workers and the control personnel to take appropriate measures, thereby effectively ensuring the safety and reliability of the lifting operation of the spreader and reducing the risk of safety accidents in port operations.

[0049] Specifically, if the inclination angle of the C-shaped plate 1 is within the threshold set by the horizontal sensor, the control module 39 does not work, and if the inclination angle 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 workers that the inclination angle of the C-shaped plate 1 is large and not safe, and also remind the workers to check the spreader, and at the same time, through the signal transmitter, it is transmitted to the crane control room to remind the control personnel not to continue to control the lifting.

[0050] Wherein, the second cover plate 4 is fixed on the C-shaped plate 1, a plurality of through holes 17 are provided on the second cover plate 4, the first power rod 5, the lifting rod 6 and the second power rod 7 penetrate the through holes 17 and are slidably arranged in the through holes 17, and the C-shaped plate 1 is provided with a groove, and the second cover plate 4 is located in the groove to seal the power groove 30; wherein, the first power rod 5, the lifting rod 6 and the second power rod 7 are all fixed with a limiting ring 18, and the limiting ring 18 in the initial state does not contact the bottom of the second cover plate 4.

[0051] Wherein, 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.

[0052] In summary, the first adjusting mechanism and the second adjusting mechanism are distributed in an X shape on the C-shaped plate 1.

[0053] When the steel coil is placed on the C-shaped plate 1, the first power rod 5 and the second power rod 7 are squeezed, when the C-shaped plate 1 lifts the steel coil upward, because the number of the first power rod 5 and the second power rod 7 is different or the same, the number of the first power rod 5 and the second power rod 7 squeezed when the steel coil is lifted is also different or the same, so that the moving distance of the first driving rod 15 and the second driving rod 21 matched and driven is also different or remains stationary; when the C-shaped plate 1 tilts to one side, the first driving rod 15 and the second driving rod 21 drive the adjusting block 28 and the connecting buckle 2 to move and move to the low end of the C-shaped plate 1, forcing the C-shaped plate 1 to tend to be in a stable balance state and locking the steel coil by the first power rod 5 and the second power rod 7.

[0054] It also includes a reinforcing locking mechanism for reinforcing the locking of the steel coil, the reinforcing locking mechanism includes an abutting piston cylinder 31 fixed in the power groove 30, an abutting sealing piston 32 slidably connected in the abutting piston cylinder 31, a third spring 33 fixed on the abutting piston cylinder 31 and the abutting sealing piston 32, a lifting rod 6 fixed on the upper end of the abutting sealing piston 32, a sliding groove 9 in communication with the abutting piston cylinder 31 provided through the C-shaped plate 1 in front and back, two resettable sealing blocks 37 slidably connected in the sliding groove 9, a short rod 27 fixed in the sliding groove 9, two fourth springs 38 fixed on the short rod 27, the fourth springs 38 being fixedly connected with the sealing blocks 37, and an abutting block 8 fixed on the sealing block 37 and capable of abutting against the steel coil.

[0055] In the initial state of the present application, after the lifting end of the crane is connected with the connecting buckle 2, the C-shaped plate 1 is lifted, and the whole device is in a horizontal state.

[0056] When the steel coil is lifted and transported into the container, the staff will pass 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 are in contact with the inner wall of the steel coil. As the C-shaped plate 1 continues to move upward, the first power rod 5, the lifting rod 6, and the second power rod 7 will be pressed downward due to the gravity of the steel coil. The amount of downward movement of the first power rod 5 and the second power rod 7 may be different or the same. This will be further explained:

[0057] When the amount of pressing of the first power rod 5 and the second power rod 7 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 will press the hydraulic oil through the first delivery pipe 14 to the first adjusting piston cylinder 12, causing the hydraulic oil in the first adjusting piston cylinder 12 to increase, thereby driving the first adjusting sealing piston 16 and the first driving rod 15 to move.

[0058] The second power rod 7 will drive the second power sealing piston 35 to move downward. The second power sealing piston 35 will press the hydraulic oil through the second delivery pipe 22 to the second adjusting piston cylinder 19, causing the hydraulic oil in the second adjusting piston cylinder 19 to increase, thereby driving the second adjusting sealing piston 20 and the second driving rod 21 to move. Since the same amount of the first power rod 5 and the second power rod 7 is pressed, the amount of hydraulic oil delivered is the same, that is, it will cause the first driving rod 15 and the second driving rod 21 to remain stationary. That is, when the steel coil is placed on the C-shaped plate 1 and the entire device is lifted, it will tend to a stable state, which can ensure the stability of the lifted steel coil.

[0059] Since the remaining first power rod 5 and the second power rod 7 are not pressed, the hydraulic oil pressed 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 thereto, thereby driving the first power sealing piston 24 and the second power sealing piston 35 to move upward, and further driving 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, and finally the limiting ring 18 is in contact with the second cover plate 4, the entire device tends to be stable, and the steel coil can be limited from both sides to avoid accidental slipping off the C-shaped plate 1.

[0060] As mentioned above, that is, no hydraulic oil is delivered into the first adjusting piston cylinder 12 and the second adjusting piston cylinder 19.

[0061] When the amount of pressing of the first power rod 5 and the second power rod 7 is different, the amount of hydraulic oil pressed into the first adjusting piston cylinder 12 and the second adjusting piston cylinder 19 is different, such as Figure 4As shown, assuming placed close to the inner side of the C-shaped plate 1, the number of extruded first power rods 5 is large, and the number of extruded second power rods 7 is small, so that 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, but since other second power rods 7 are not extruded, when the second power rod 7 is extruded, the hydraulic oil in the corresponding second power piston cylinder 34 will flow into other second power piston cylinders 34, and since the adjusting block 28 is driven to move, the hydraulic oil in the second adjusting piston cylinder 19 is also driven to move into other second adjusting piston cylinders 19, and the corresponding other second power rods 7 move upward to shield the steel coil, so that the adjusting block 28 and the connecting buckle 2 move toward the inner side of the C-shaped plate 1, and finally the entire device is hoisted to be stable, ensuring the safety of hoisting, and facilitating the placement of the steel coil in the container.

[0062] When the number of extruded first power rods 5 is less than the number of extruded second power rods 7, it is the opposite.

[0063] However, in actual hoisting construction, the steel coil will be placed close to the inner side of the C-shaped plate 1.

[0064] In the above, the lifting rod 6 will always be extruded, and the lifting rod 6 drives the abutting sealing piston 32 to move, so that the internal hydraulic oil can be extruded into the chute 9, and the hydraulic oil in the chute 9 drives the sealing block 37 and the abutting block 8 to move, and finally the abutting block 8 abuts against the inner wall of the steel coil, so that the arc of the support of the steel coil is increased; the abutting of the abutting block 8 against the steel coil is fed back to the sealing block 37, and the hydraulic oil is fed back to the lifting rod 6, so that the lifting rod 6 and the abutting block 8 form a triangular support for the steel coil, and finally tend to a stable state, and this state is fed back to the first power rod 5 and the second power rod 7, so that the downward movement distance is controlled according to the downward movement distance of the lifting rod 6.

[0065] Due to the different inner diameters of the steel coil winding drums, the movement distance of the abutting block 8 is different, and the downward movement distance of the lifting rod 6 is also different, and the downward movement distance of the first power rod 5 and the second power rod 7 is also different, but finally all can realize the adjustment of the adjusting block 28, so that the entire device is hoisted to be stable, ensuring the safety of hoisting work.

[0066] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
