Description

Technical Field

[0001] The present invention relates to the technical field of building hoisting construction, and in particular to a self-powered, automatically unhooking and slowly descending large-scale stable distribution hanger and a construction method. Background Art

[0002] Marine engineering is one of the key development directions in my country's future engineering construction field. Considering the difficulty of offshore assembly, large-scale modular assembly production on shore and large-scale module splicing at sea are the future development directions of marine engineering construction methods.

[0003] The production, offshore transportation and installation of large modular terminals are inseparable from lifting; and the lifting of large modular components is inseparable from large distribution hangers. The current distribution hangers in marine engineering have the following problems:

[0004] (1) The shoulder beam under the distribution beam shakes and deflects when the hanger is mounted;

[0005] (2) The hanger needs an external power supply to unhook;

[0006] (3) After the rope is unhooked, it falls freely downwards, which may easily cause entanglement or damage the platform's auxiliary equipment;

[0007] (4) There is a lack of remote observation, positioning, and alignment systems, and manual assistance is required for positioning, resulting in low human-machine efficiency. Summary of the Invention

[0008] In response to the above-mentioned technical problems existing in existing hangers, the purpose of the present invention is to provide a large-scale stable distribution hanger with self-powered automatic uncoupling and slow-down, and a construction method. By setting a shoulder beam with a passive stabilization device on the large distribution hanger, integrating an intelligent positioning, sighting and alignment module, an automatic uncoupling and rope slow-down control module, and using a light storage self-powered module to solve the power supply problem, the above components are organically combined through a control circuit. The device adopts a modular design, which can realize the main body factory production, rapid on-site installation, and remote control operation; at the same time, a supporting construction and installation process is designed, which can be effectively combined with the device of this patent to ensure the rational use of the device.

[0009] In order to achieve the above-mentioned purpose, the self-powered automatic uncoupling and slow-descent large-scale stable distribution hanger provided by the present invention includes a frame body, a photovoltaic energy storage module, and a control module. The four corners of the frame body are movably connected to the shoulder beam through a damping hinge ring assembly. The damping hinge ring can provide damping buffering for the rotation of the shoulder beam. A slow-descent control assembly is provided in the middle of the shoulder beam. A slow-descent uncoupling module is respectively arranged at the bottom of both ends of the shoulder beam. The slow-descent uncoupling module is connected to the slow-descent control assembly through a lifting rope. The slow-descent control assembly, the slow-descent uncoupling module and the lifting rope are connected and cooperated to form a lifting rope retracting assembly. An automatic uncoupling lock and a camera unit are provided at the bottom of the slow-descent uncoupling module.

[0010] The outer sides of both ends of the shoulder pole beam are respectively provided with electromagnetic automatic unhooking devices;

[0011] The main hoisting steel cable is passed through the electromagnetic automatic unhooking device and connected to the automatic unhooking lock at the bottom of the slow-down unhooking module; when the hoisting is in place, the electromagnetic automatic unhooking device is opened, the main hoisting steel cable falls, and the slow-down unhooking module is driven down. The hoisting rope is pulled down by the slow-down unhooking module, and the slow-down control component plays a role, causing the main hoisting steel cable to fall slowly and evenly to the lowest point; after that, the automatic unhooking lock releases the connection with the main hoisting steel cable, and at the same time, the slow-down control component drives the slow-down unhooking module to rise to the bottom of the shoulder beam. The camera unit can provide remote image images during the work process to assist in alignment.

[0012] The photovoltaic energy storage module and the control module are both installed on the frame. The photovoltaic energy storage module can generate and store photovoltaic power for powering the descent control component, the descent uncoupling module and the electromagnetic automatic uncoupling device.

[0013] The control module is used to control the descent control component, the descent uncoupling module, the electromagnetic automatic uncoupling device and the photovoltaic energy storage module.

[0014] Furthermore, the damping hinge ring assembly includes a first earring and a second earring, a third earring is provided between the first earring and the second earring, a first damping disc is provided between the first earring and the third earring, and a second damping disc is provided between the third earring and the second earring;

[0015] The first earring, the second earring, the third earring, the first damping plate, and the second damping plate are sequentially provided with coaxial rotating holes and a plurality of fastening holes;

[0016] The first earring and the second earring are fixed to the first damping plate and the second damping plate respectively by a plurality of fasteners passing through the fastening holes;

[0017] Ball bearings are provided in the rotating holes of the first earring and the second earring;

[0018] The third earring is fixed on the frame, and the first earring and the second earring are fixed on the shoulder beam. The third earring is fixed in the middle of the pin shaft, and passes through the first earring, the second earring, the first damping plate, and the second damping plate in sequence and are fixed; the ball bearing enables the first earring and the second earring to rotate around the pin shaft through the rotating hole, and the first damping plate and the second damping plate are filled with viscous damping material. When the first earring and the second earring rotate through the rotating hole, they can drive the internal mechanism of the first damping plate and the second damping plate to rotate and shear the viscous damping material inside, thereby generating damping energy consumption.

[0019] Furthermore, the descent control assembly includes a housing, a barrel winch, a reducer, and a recovery motor. Both ends of the barrel winch are rotatably arranged inside the housing through bearing assemblies.

[0020] The reducer and the recovery motor are respectively located at both ends of the housing and are respectively connected to the barrel winch. The reducer, the recovery motor and the barrel winch are coaxially arranged. The bearing assembly passes through the coaxially arranged barrel winch, the reducer and the recovery motor so that the three can rotate coaxially.

[0021] The barrel-shaped winch can be used to wrap one end of the lifting rope, and the other end of the lifting rope is wrapped around the slow-descent and unhooking module. When the slow-descent and unhooking module falls, it drives the lifting rope to go down, and the lifting rope drives the reducer and the barrel-shaped winch to rotate. The reducer can reduce the speed, thereby reducing the descending speed of the slow-descent and unhooking module. After the recovery motor is used for lifting, the barrel-shaped winch is driven to rotate by the recovery motor, so that the lifting rope is pulled upward, and the lifting rope drives the slow-descent and unhooking module to be pulled upward.

[0022] Furthermore, the slow-down unhooking module includes a connecting plate, a lifting lug for winding a lifting rope on the top of the connecting plate, an automatic unhooking lock on the bottom, a battery pack, a transmitting antenna and a camera unit on one side, and a controller on the other side. The controller is connected to the automatic unhooking lock and can control the opening and closing of the automatic unhooking lock;

[0023] The battery pack, controller, and transmitting antenna are all connected to the automatic unhooking lock and the camera unit, and can serve as energy supply, remote control, and signal transmitting devices for the automatic unhooking lock and the camera unit, respectively.

[0024] Furthermore, the two ends of the shoulder beam are provided with ear plate assemblies with holes, which cooperate with the electromagnetic automatic unhooking device to lock and unlock the main lifting cable;

[0025] The perforated ear plate assembly includes a first perforated ear plate, a second perforated ear plate and a third perforated ear plate. The first perforated ear plate, the second perforated ear plate and the third perforated ear plate are arranged at intervals. Spaces for placing circular rings at both ends of the main lifting cable are formed between the first perforated ear plate and the second perforated ear plate, and between the third perforated ear plate and the second perforated ear plate.

[0026] Furthermore, the electromagnetic automatic unhooking device includes a housing, a pin shaft, an electromagnet and a controller, a balance spring and a sealing plate;

[0027] The shell and the sealing plate are connected and assembled to form a cavity; the cavity is provided with a coaxially mounted pin rod, an electromagnet and a controller, a balance spring,

[0028] A magnetic plate is sleeved on the pin shaft, and the pin shaft is supported inside the cavity by the magnetic plate; one end of the electromagnet and the controller is fixedly connected to the sealing plate, and a guide hole is provided in the housing, and the pin shaft is movably inserted into the guide hole, and one end of the balance spring is connected to the magnetic plate, and the other end is connected to the other end of the electromagnet and the controller;

[0029] The magnetic plate cooperates with the electromagnet and the controller. When the electromagnet and the controller are energized, the magnetic plate resists the elastic force of the balance spring and moves toward the electromagnet and the controller through magnetic force, thereby driving the shaft pin to move toward the electromagnet and the controller. When the electromagnet and the controller are deenergized, the elastic restoring force of the balance spring causes the magnetic plate and the shaft pin to move in the opposite direction.

[0030] The electromagnet and the controller are connected to the photovoltaic energy storage module and the control module respectively;

[0031] The housing is arranged on one side of the third perforated ear plate, and the pin rod is coaxial with the holes on the first perforated ear plate, the second perforated ear plate and the third perforated ear plate;

[0032] By cutting off the power of the electromagnet and the controller, the balance spring can be released, so that the pin rod can move along the guide hole and pass through the holes of the third perforated ear plate, the second perforated ear plate and the first perforated ear plate in sequence, and can also pass through the end rings of the main lifting cable between the first perforated ear plate and the second perforated ear plate and between the third perforated ear plate and the second perforated ear plate at the same time, thereby fixing the rings at both ends of the main lifting cable;

[0033] By energizing the electromagnet and the controller, the balance spring can be compressed, causing the pin shaft rod to move in the opposite direction; when the pin shaft rod moves in the opposite direction to between the second ear plate with a hole and the third ear plate with a hole, the pin shaft rod disengages from the end ring of the main lifting cable between the first ear plate with a hole and the second driving ear plate, and the ring at one end of the main lifting cable can be released;

[0034] When the pin rod continues to move in the opposite direction to the outside of the third perforated ear plate, the pin rod disengages from the main lifting cable end ring between the second perforated ear plate and the third driving ear plate, and can release the other end ring of the main lifting cable.

[0035] In order to achieve the above object, the present invention provides a construction method for a self-powered, automatically unhooking and slowly lowering large-scale stable distribution hanger, which is used for any of the above items, and the construction method includes:

[0036] S1: Place the large stable distribution hanger near the object to be lifted, energize the electromagnetic automatic unhooking device, open the pin to the outside of the third perforated lug, and place the ring at one end of the main lifting cable between the second and third perforated lugs. After the main lifting cable is placed, the electromagnet and its controller are de-energized, the balancing spring is released, and the pin is pushed out to cross all the perforated lugs and to the outside of the first perforated lug, completing the pin fixation.

[0037] S2: Lift the large stable distribution hanger above the object to be lifted, and slowly lower it so that the ring at the other end of the main lifting steel passes through the binding position of the object to be lifted and is wrapped and stabilized. Power on the electromagnetic automatic unhooking device, open the pin shaft rod to the second perforated ear plate and close to the side of the first perforated ear plate. At this time, the free end of the pin shaft rod is out of the gap between the first perforated ear plate and the second perforated ear plate and is located in the gap between the second perforated ear plate and the third perforated ear plate. Use a climbing vehicle to place the ring at the other end of the main lifting steel cable between the second perforated ear plate and the first perforated ear plate. When the ring at the other end of the main lifting steel cable is placed, the electromagnet and its controller are powered off, the balancing spring is released, and the pin shaft rod is pushed out to cross all the perforated ear plates and to the left side of the first perforated ear plate to complete the fixing of the pin shaft rod. Connect the end ring of the main lifting steel cable between the second perforated ear plate and the first perforated ear plate with the automatic unhooking lock. At this time, the lifting rope is in the recovery stage, and the slow-descent unhooking module is located at the bottom position of the vibration-damping shoulder beam. The installation and fixation of each main lifting steel cable are completed in sequence.

[0038] S3: Slowly lift until all main lifting cables are tensioned. During this process, the damping disc passes through, generating damping energy and rapidly reducing the swaying of the shoulder beam. Lift in accordance with relevant specifications until the object is lifted to the designated location.

[0039] S4: Slowly lower the large stable distribution hanger until the main hoisting cable only bears its own weight. Power on the electromagnetic automatic unhooking device, open the free end of the pin shaft to the hole of the second perforated ear plate and close to the side of the first perforated ear plate, release and drop the ring at one end of the main hoisting cable between the second perforated ear plate and the first perforated ear plate, drive the slow-down unhooking module to descend, and the rope is pulled down by the slow-down unhooking module, driving the cylindrical hoisting rope winch, the reducer rotates, and the reducer works, so that the main hoisting cable slowly and evenly drops to the lowest point to avoid rebound and entanglement; after that, the automatic unhooking lock releases the main hoisting cable, and at the same time, the recovery motor drives the cylindrical hoisting rope winch, the rope, and the slow-down unhooking module to rise to the bottom position of the shoulder beam; during the process, the wireless camera unit provides remote image images to assist in crane alignment;

[0040] S5: Slowly raise the large stable distribution hanger to the predetermined position and wait for the next lifting.

[0041] This invention provides a large, stable, self-powered, automatically unhooking and slowly lowering distribution hanger and its construction method. This system incorporates a shoulder beam with a passive stabilization device on the large distribution hanger, integrated with an intelligent positioning, sighting, and alignment module, an automatic unhooking, and a rope-suspension slowly lowering control module, and a solar-powered, self-storage energy module to address power supply issues. These components are organically combined through a control circuit. The modular design of the device allows for factory fabrication of the main structure, rapid on-site installation, and remote control operation. A supporting construction and installation process has also been designed that can be effectively combined with the patented device to ensure its proper use. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application is further described below in combination with specific figures.

[0059] The figure shows that: Figures 1-11 The figure shows that:

[0060] According to the figure, the self-powered automatic unhooking and slow descending large stable distribution hanger provided by the application includes seven components, namely, a frame body 100, a photovoltaic energy storage module 200, a control module 300, a pole beam 400, a slow descending control assembly 500, a slow descending unhooking module 600, and an electromagnetic automatic unhooking device 700.

[0061] The frame body 100 is the main structure and is used to bear other components.

[0062] The four corners of the frame 100 are movably connected to the shoulder beam 400 through the damping hinge ring assembly 800. The damping hinge ring 800 can provide damping buffering for the shaking of the shoulder beam 400.

[0063] A descending control assembly 500 is provided in the middle of the shoulder pole beam 400, and descending unhooking modules 600 are arranged at the bottom of both ends of the shoulder pole beam 400. The descending unhooking module 600 is connected to the descending control assembly 500 through a sling 900. The descending control assembly 500, the descending unhooking module 600 and the sling 900 are connected and cooperated to form a sling retracting assembly. An automatic unhooking lock 612 and a camera unit 615 are provided at the bottom of the descending unhooking module 600.

[0064] The outer sides of both ends of the shoulder pole beam 400 are respectively provided with electromagnetic automatic unhooking devices 700;

[0065] By passing the main hoisting steel cable 1000 through the electromagnetic automatic unhooking device 700 and connecting it to the automatic unhooking lock 612 at the bottom of the slow-down unhooking module 600; when the hoisting is in place, the electromagnetic automatic unhooking device 700 is opened, the main hoisting steel cable 1000 falls, driving the slow-down unhooking module 600 to descend, and the hoisting rope 900 is pulled down by the slow-down unhooking module 600, and the slow-down control component 500 plays a role, causing the main hoisting steel cable 1000 to fall slowly and uniformly to the lowest point; after that, the automatic unhooking lock 612 releases the connection with the main hoisting steel cable 1000, and at the same time, the slow-down control component 500 drives the slow-down unhooking module 600 to rise to its original position. The camera unit 615 can provide remote image pictures during the working process to assist in alignment.

[0066] The photovoltaic energy storage module 200 and the control module 300 are both installed on the frame. The photovoltaic energy storage module 200 can generate and store photovoltaic power for powering the descent control assembly 500, the descent uncoupling module 600, and the electromagnetic automatic uncoupling device 700.

[0067] The control module 300 is used to control the descent control assembly 500 , the descent uncoupling module 600 , the electromagnetic automatic uncoupling device 700 and the photovoltaic energy storage module 200 .

[0068] Specifically, the frame 100 is composed of a spatial steel structure truss, and its four corners are connected to the shoulder beam 400 through a damping hinge ring assembly 800.

[0069] like Figure 3 , Figure 6The damping hinge ring assembly 800 is located in the middle of the top of the shoulder beam 400. The damping hinge ring assembly 800 includes a first earring 810, a second earring 820, a third earring 830 is provided between the first earring 810 and the second earring 820, a first damping disc 840 is provided between the first earring 810 and the third earring 830, and a second damping disc 850 is provided between the third earring 830 and the second earring 820.

[0070] The first earring 810, the second earring 820, the third earring 830, the first damping plate 840, and the second damping plate 850 are sequentially provided with a coaxial rotation hole 801 and a plurality of fastening holes 802;

[0071] The first earring 810 and the second earring 820 are fixed together with the first damping plate 840 and the second damping plate 850 respectively by a plurality of fasteners passing through the fastening holes 802;

[0072] Ball bearings 860 are provided in the rotating holes 801 of the first earring 810 and the second earring 820 .

[0073] The third earring 830 is fixed on the frame 100, and the first earring 810 and the second earring 820 are fixed on the shoulder beam 400. The third earring 830 is fixed to the middle of the pin shaft 110, and passes through the first earring 810, the second earring 820, the first damping plate 840, and the second damping plate 850 in sequence and fixed; the ball bearing 860 allows the first earring 810 and the second earring 820 to rotate around the pin shaft 110 through the rotating hole 801, and the first damping plate 840 and the second damping plate 850 are filled with viscous damping material. When the first earring 810 and the second earring 820 rotate through the rotating hole 801, they can drive the internal mechanisms (such as blades) of the first damping plate 840 and the second damping plate 850 to rotate and shear the viscous damping material inside, thereby generating damping energy consumption.

[0074] The first damping disc 840 and the second damping disc 850 are conventional technologies in the existing market. They are integral products with the same structure. There is a rotating hole in the center of the middle circle. The disc is a hollow structure with a structure similar to a fan blade inside. The fan blade is connected to the rotating hole, and the middle of the hollow structure is filled with viscous damping material. When the first earring 810 and the second earring 820 rotate, the rotating hole is driven to rotate, and then the blade is driven to rotate. The blade shears the internal viscous material. Similar products are already available on the market, so the specific details will not be elaborated.

[0075] Furthermore, if Figure 8 The descent control assembly 500 includes a housing 510, a barrel winch 520, a reducer 530, and a recovery motor 540. Both ends of the barrel winch 520 are rotatably mounted inside the housing 510 through bearing assemblies 550.

[0076] The reducer 530 and the recovery motor 540 are respectively located at both ends of the shell 510 and are respectively connected to the barrel winch 520. The reducer 530, the recovery motor 540 and the barrel winch 520 are coaxially arranged. The bearing assembly 550 passes through the coaxially arranged barrel winch 520, the reducer 530 and the recovery motor 540 so that the three can rotate coaxially.

[0077] The barrel-shaped winch 520 can be used to wrap one end of the lifting rope 900, and the other end of the lifting rope 900 is wrapped around the slow-descent and unhooking module 600. When the slow-descent and unhooking module 600 falls, it drives the lifting rope 900 to descend, and the lifting rope 900 drives the reducer 530 and the barrel-shaped winch 520 to rotate. The reducer 530 can reduce the rotation speed, thereby reducing the descending speed of the slow-descent and unhooking module 600. After the recovery motor 540 is used for lifting, the barrel-shaped winch 520 is driven to rotate by the recovery motor 540, so that the lifting rope 900 is pulled upward, and the lifting rope 900 thereby drives the slow-descent and unhooking module 600 to be pulled upward.

[0078] The descent control assembly 500 of such a structure cooperates with the descent decoupling module 600, as shown in FIG. Figure 9 The slow-descent unhooking module 600 includes a connecting plate 610, a top of which is provided with a lifting ear 611 for winding the lifting rope 900, a bottom of which is provided with an automatic unhooking lock 612, a battery pack 613, a transmitting antenna 614 and a camera unit 615 on one side, and a controller 616 on the other side. The controller 616 is connected to the automatic unhooking lock 612 and can control the opening and closing of the automatic unhooking lock 612.

[0079] The battery pack 613 , the controller 616 , and the transmitting antenna 614 are all connected to the automatic unhooking lock 612 and the camera unit 615 , and can serve as power supply, remote control, and signal transmitting devices for the automatic unhooking lock 612 and the camera unit 615 , respectively.

[0080] like Figure 3 , Figure 4 The two ends of the shoulder beam 400 are provided with ear plate assemblies 410 with holes. The ear plate assemblies 410 with holes cooperate with the electromagnetic automatic unhooking device 700 to lock and unlock the main lifting cable 1000.

[0081] The perforated ear plate assembly 410 includes a first perforated ear plate 411, a second perforated ear plate 412, and a third perforated ear plate 413. The first perforated ear plate 411, the second perforated ear plate 412, and the third perforated ear plate 413 are spaced apart. Spaces for accommodating the rings at both ends of the main sling cable 1000 are formed between the first perforated ear plate 411 and the second perforated ear plate 412, and between the third perforated ear plate 413 and the second perforated ear plate 412.

[0082] In conjunction with it, such as Figure 10 , Figure 11The electromagnetic automatic unhooking device 700 includes a housing 710 , a pin shaft 720 , an electromagnet and controller 730 , a balance spring 740 and a sealing plate 750 .

[0083] The housing 710 and the sealing plate 750 are connected and assembled to form a cavity; the cavity is provided with a coaxially mounted pin shaft 720, an electromagnet and controller 730, and a balance spring 740.

[0084] A magnetic plate 721 is mounted on the pin shaft 720, supporting the pin shaft 720 within the cavity. One end of the electromagnet and controller 730 is fixedly connected to the sealing plate 750. A guide hole 711 is provided in the housing 710, through which the pin shaft 720 is movably inserted. One end of the balance spring 740 is connected to the magnetic plate 721, and the other end is connected to the other end of the electromagnet and controller 730.

[0085] The magnetic plate 721 cooperates with the electromagnet and the controller 730. When the electromagnet and the controller 730 are energized, the magnetic plate 721 resists the elastic force of the balance spring 740 and moves toward the electromagnet and the controller 730 through magnetic force, thereby driving the shaft pin 720 to move toward the electromagnet and the controller 730. When the electromagnet and the controller 730 are deenergized, the elastic restoring force of the balance spring 740 causes the magnetic plate 721 and the shaft pin 720 to move in the opposite direction.

[0086] The electromagnet and the controller 730 are connected to the photovoltaic energy storage module 200 and the control module 300 respectively;

[0087] The housing 710 is disposed on one side of the third perforated ear plate 413 , and the pin shaft 720 is coaxial with the holes on the first perforated ear plate 411 , the second perforated ear plate 412 , and the third perforated ear plate 413 ;

[0088] By de-energizing the electromagnet and the controller 730, the balance spring 740 is released, so that the pin shaft rod 720 moves along the guide hole 711 and can sequentially penetrate the holes of the third perforated ear plate 413, the second perforated ear plate 412, and the first perforated ear plate 411, and can simultaneously penetrate the end rings of the main lifting cable 1000 between the first perforated ear plate 411 and the second perforated ear plate 412 and between the third perforated ear plate 413 and the second perforated ear plate 412, thereby fixing the rings at both ends of the main lifting cable 1000;

[0089] By energizing the electromagnet and the controller 730, the balance spring 740 can be compressed, causing the pin shaft rod 720 to move in the reverse direction; when the pin shaft rod 720 moves in the reverse direction to between the second perforated ear plate 412 and the third perforated ear plate 413, the pin shaft rod 720 disengages from the end ring of the main lifting cable 1000 between the first perforated ear plate 411 and the second driving ear plate 412, thereby releasing the end ring of the main lifting cable 1000;

[0090] When the pin rod 720 continues to move in the opposite direction to the outside of the third perforated ear plate 413, the pin rod 720 disengages from the end ring of the main lifting cable 1000 between the second perforated ear plate 412 and the third driving ear plate 413, and the other end ring of the main lifting cable 1000 can be released;

[0091] In actual use, when the power is off, the pin 720 is inserted into the holes on the first perforated ear plate 411, the second perforated ear plate 412, and the third perforated ear plate 413. The rings at both ends of the main lifting cable 1000 are respectively mounted on the pin 720 and located between the first perforated ear plate 411 and the second perforated ear plate 412, and between the second perforated ear plate 412 and the third perforated ear plate 413. When the electromagnet and its controller 730 are energized, the balance spring 740 is compressed. When the free end of the pin 720 is pulled to move out of the gap between the first perforated ear plate 411 and the second perforated ear plate 412, the ring at one end of the main lifting cable 100 is released. When the free end of the pin is further pulled to move out of the gap between the second perforated ear plate 412 and the third perforated ear plate 413, the ring at the other end of the main lifting cable 1000 is released.

[0092] When the rings at both ends of the main lifting rope 100 are placed respectively, the electromagnet and its controller 730 are powered off, the balance spring 740 is released, and the pin rod 720 is pushed out to cross all the perforated ear plates and to the outside of the first perforated ear plate 411, completing the fixation of the pin rod 720.

[0093] like Figure 12 Based on the self-powered, automatically unhooking and slowly descending large-scale stable distribution hanger constructed by the above scheme, this scheme also provides a construction method. The construction steps are as follows:

[0094] S1: Place the large stable distribution hanger near the object to be hoisted 1100, power on the electromagnetic automatic unhooking device 700, open the pin rod 720 to the outside of the third perforated ear plate 413, and place the ring at one end of the main lifting cable 1000 between the second perforated ear plate 412 and the third perforated ear plate 413. When the main lifting cable 1000 is placed, the electromagnet and its controller 730 are powered off, the balance spring 740 is released, and the pin rod 720 is pushed out to cross all the perforated ear plates and to the outside of the first perforated ear plate 411, completing the fixation of the pin rod 720.

[0095] After the ring at the other end of the main lifting steel cable 1000 is placed, the electromagnet and its controller 730 are powered off, the balancing spring 740 is released, and the pin shaft 720 is released. When the lifting rope 900 is in the recovery stage, the decoupling module 600 is located at the bottom of the shock-absorbing shoulder beam 400, and the installation and fixation of each main lifting rope 1000 are completed in sequence. At this time, the main lifting rope 1000 is U-shaped, and the rings at both ends are respectively between the second and third perforated ear plates 412 and the third perforated ear plate 413 and between the first and second perforated ear plates 411 and 412, and are sleeved on the pin shaft 720 and fixed. At the same time, the main lifting rope 1000 is also connected to the object to be lifted 1100 and the automatic decoupling rope 612.

[0096] S3: Slowly lift until all main lifting cables are tensioned. During this process, the damping disc passes through, generating damping energy and quickly reducing the swaying of the shoulder beam 400. Lift in accordance with relevant specifications, and the object to be lifted 1100 is moved to the predetermined location.

[0097] S4: Slowly lower the large stable distribution hanger until the main hoist cable 1000 only bears its own weight. The electromagnetic automatic unhooking device 700 is energized, the free end of the pin shaft rod 720 is opened and moved into the hole of the second perforated ear plate 412, close to the side of the first perforated ear plate 411, and the circular ring at one end of the main lifting rope 100 located between the second perforated ear plate 412 and the first perforated ear plate 411 is released and falls, driving the slow-down unhooking module 600 to descend. The lifting rope 900 is pulled down by the slow-down unhooking module 600, driving the cylindrical lifting rope winch 520 and the reducer 530 to rotate. The reducer 530 works to make the main lifting rope slowly and evenly fall to the lowest point to avoid rebound and entanglement; thereafter, the automatic unhooking lock 612 releases the main lifting rope 1000. At the same time, the recovery motor 540 drives the cylindrical lifting rope winch 520, the lifting rope 900, and the slow-down unhooking module 600 to rise to the bottom position of the shoulder beam 400; during this process, the wireless camera unit 615 provides remote image images to assist in crane alignment.

[0098] S5: Slowly raise the large stable distribution hanger to the predetermined position and wait for the next lifting.
