Description

Technical Field

[0001] The 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-module assembly production on shore and large-module splicing at sea are the future development directions of construction methods.

[0003] The production, offshore transportation and installation of large modular docks cannot be separated from lifting; and the lifting of large modular components cannot be separated from large distribution hangers. The current distribution hangers for offshore engineering have the following problems:

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

[0005] (2) The hanger unhooking requires an external power supply;

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

[0007] (4) There is a lack of long-range observation, positioning, and alignment systems, and manual assisted positioning is required, resulting in low human-machine efficiency. Summary of the invention

[0008] In view of the above technical problems existing in the existing hangers, the purpose of the present invention is to provide a large-scale stable distribution hanger and construction method with self-powered automatic unhooking and slow-down, 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 unhooking and rope slow-down control module, and using a light storage self-powered module to solve the power supply problem, and organically combining the above components through a control circuit. The device adopts a modular design, which can realize the main body factory production, on-site rapid 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 reasonable use of the device.

[0009] In order to achieve the above-mentioned purpose, the self-powered automatic unhooking slow-descent large-scale stable distribution hanger provided by the present invention comprises 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. Slow-descent unhooking modules are respectively arranged at the bottom of both ends of the shoulder beam. The slow-descent unhooking module is connected to the slow-descent control assembly through a suspension rope. The slow-descent control assembly, the slow-descent unhooking module and the suspension rope are connected and matched to form a suspension rope retracting assembly. An automatic unhooking lock and a camera unit are provided at the bottom of the slow-descent unhooking module.

[0010] Electromagnetic automatic unhooking devices are respectively provided on the outer sides of both ends of the shoulder pole beam;

[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, driving the slow-down unhooking module to descend, the hoisting rope is pulled down by the slow-down unhooking module, and the slow-down control component plays a role, making the main hoisting steel cable slowly fall to the lowest point at a uniform speed; then, 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 pictures during the work process to assist in alignment.

[0012] The photovoltaic energy storage module and the control module are both arranged on the frame. The photovoltaic energy storage module can generate photovoltaic power and store it, which is used to power the descent control component, the descent unhooking module and the electromagnetic automatic unhooking device.

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

[0014] Further, the damping hinge ring assembly comprises a first earring and a second earring, a third earring is arranged between the first earring and the second earring, a first damping disk is arranged between the first earring and the third earring, and a second damping disk is arranged 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, the second earring, the first damping plate, and the second damping plate are fixed together respectively by a plurality of fasteners passing through the fastening holes;

[0017] Ball bearings are arranged 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 to the middle of the pin shaft, and the first earring, the second earring, the first damping disk, and the second damping disk are sequentially passed through and fixed; the ball bearing allows the first earring and the second earring to rotate around the pin shaft through the rotating hole, and the first damping disk and the second damping disk 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 disk and the second damping disk 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 two 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 down, and the lifting rope drives the reducer and the barrel-shaped winch to rotate. The reducer can reduce the rotation speed, thereby reducing the descending speed of the slow-descent and unhooking module. After the lifting is completed, the recovery motor drives the barrel-shaped winch to rotate through 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-descent unhooking module includes a connecting plate, a lifting lug for winding a lifting rope is provided on the top of the connecting plate, an automatic unhooking lock is provided on the bottom, a battery pack, a transmitting antenna and a camera unit are provided on one side, and a controller is provided 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, and the ear plate assemblies with holes 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, and spaces for accommodating 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 comprises a housing, a pin shaft rod, an electromagnet and a controller, a balance spring and a sealing plate;

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

[0028] A magnetic plate is sleeved on the pin shaft rod, and the pin shaft rod is supported inside the cavity by the magnetic plate; one end of the electromagnet and the controller is connected and fixed to the sealing plate, a guide hole is provided in the shell, and the pin shaft rod is movably inserted into the guide hole, 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 powered on, 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 powered off, 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 ear plate with holes, and the pin shaft rod is coaxial with the holes on the first ear plate with holes, the second ear plate with holes and the third ear plate with holes;

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

[0033] By energizing the electromagnet and the controller, the balance spring can be compressed, so that the pin shaft rod moves in the opposite direction; when the pin shaft rod moves in the opposite direction to between the second ear plate with holes and the third ear plate with holes, the pin shaft rod is separated from the end ring of the main lifting cable between the first ear plate with holes 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 ear plate with holes, the pin rod disengages from the end ring of the main lifting cable between the second ear plate with holes 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 automatic unhooking and slow-down large-scale stable distribution hanger, which is used for any one of the above items, and the construction method includes:

[0036] S1: Place the large stable distribution hanger near the object to be hoisted, energize the electromagnetic automatic unhooking device, open the pin shaft rod to the outside of the third ear plate with holes, and place the ring at one end of the main hoisting cable between the second ear plate with holes and the third ear plate with holes. When the main hoisting cable is placed, the electromagnet and its controller are powered off, the balance spring is released, and the pin shaft rod is pushed out to cross all the ear plates with holes and to the outside of the first ear plate with holes, completing the fixing of the pin shaft rod;

[0037] S2: Lift the large stable distribution hanger above the object to be hoisted, and slowly descend so that the ring at the other end of the main hoist steel passes through the binding position of the object to be hoisted, and wraps and stabilizes it, energize 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 separated from 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 the aerial platform to place the ring at the other end of the main hoist steel cable between the second perforated ear plate and the first perforated ear plate, when the ring at the other end of the main hoist steel cable is placed, the electromagnet and its controller are powered off, the balance spring is released, the pin shaft rod is pushed out to cross all the perforated ear plates, to the left side of the first perforated ear plate, the pin shaft rod is fixed, and the end ring of the main hoist steel cable between the second perforated ear plate and the first perforated ear plate is connected to the automatic unhooking lock, at this time the hoist rope is in the recovery stage, the slow-descent unhooking module is located at the bottom of the vibration-damping shoulder beam, and the installation and fixation of each main hoist steel cable are completed in sequence;

[0038] S3: Slowly lift until the main lifting cables are tensioned. During the process, the damping disc passes through, generating damping energy consumption, quickly reducing the shaking of the shoulder beam, and lifting in accordance with relevant specifications until the object to be lifted reaches the predetermined 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 rod 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 to rotate, and the reducer works, so that the main hoisting rope slowly and evenly drops to the lowest point to avoid rebound and entanglement; then, the automatic unhooking lock releases the main hoisting rope, 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 of the shoulder beam; during the process, the wireless camera unit provides remote image pictures to assist the crane in alignment;

DETAILED DESCRIPTION

[0058] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0059] See also Figure 1-Figure 11 , which shows a structural schematic diagram of a self-powered, automatically unhooking and slowly descending large-scale stable distribution hanger provided by the present invention.

[0060] According to the diagram, the self-powered automatic uncoupling and slow-descent large-scale stable distribution hanger provided by the present invention includes seven components: a frame 100, a photovoltaic energy storage module 200, a control module 300, a shoulder beam 400, a slow-descent control component 500, a slow-descent uncoupling module 600, and an electromagnetic automatic uncoupling device 700.

[0061] The frame 100 is a structural main body used to carry 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, and the damping hinge ring 800 can provide damping buffering for the shaking of the shoulder beam 400;

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

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

[0065] The main hoisting steel cable 1000 is passed through the electromagnetic automatic unhooking device 700 and connected to the automatic unhooking lock 612 at the bottom of the slow-descent 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-descent unhooking module 600 to descend, and the hoisting rope 900 is pulled down by the slow-descent unhooking module 600. The slow-descent control component 500 plays a role, so that the main hoisting steel cable 1000 slowly falls to the lowest point at a uniform speed; after that, the automatic unhooking lock 612 releases the connection with the main hoisting steel cable 1000, and at the same time, the slow-descent control component 500 drives the slow-descent 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 arranged on the frame. The photovoltaic energy storage module 200 can generate and store photovoltaic power for supplying power to the descent control assembly 500, the descent unhooking module 600 and the electromagnetic automatic unhooking device 700.

[0067] The control module 300 is used to control the slow-descent control assembly 500 , the slow-descent unhooking module 600 , the electromagnetic automatic unhooking 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 arranged between the first earring 810 and the second earring 820, a first damping plate 840 is arranged between the first earring 810 and the third earring 830, and a second damping plate 850 is arranged 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 rotating hole 801 and a plurality of fastening holes 802;

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

[0072] Ball bearings 860 are disposed 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 in the middle of the pin shaft 110, and the third earring 830 is passed through the first earring 810, the second earring 820, the first damping disk 840, and the second damping disk 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 disk 840 and the second damping disk 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 disk 840 and the second damping disk 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 existing conventional technologies, which are integral products with the same structure. There is a rotating hole in the center of the middle circle, and 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, and 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 arranged 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 lifting is completed, the recovery motor 540 drives the barrel-shaped winch 520 to rotate through 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 structure cooperates with the descent release module 600, such as Fig. 9 The slow-descent unhooking module 600 includes a connecting plate 610, a top of the connecting plate 610 is provided with a lifting ear 611 for winding the lifting rope 900, a bottom of the connecting plate 610 is provided with an automatic unhooking lock 612, one side is provided with a battery pack 613, a transmitting antenna 614 and a camera unit 615, and the other side is provided with a controller 616, 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 arranged at intervals, and spaces for accommodating the rings at both ends of the main suspension steel 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, Fig.10 , Fig.11The electromagnetic automatic unhooking device 700 includes a housing 710 , a pin shaft rod 720 , an electromagnet and a controller 730 , a balance spring 740 and a sealing plate 750 .

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

[0084] A magnetic plate 721 is sleeved on the pin shaft 720, and the pin shaft 720 is supported inside the cavity by the magnetic plate 721; one end of the electromagnet and controller 730 is connected and fixed to the sealing plate 750. A guide hole 711 is provided in the housing 710, and the pin shaft 720 is movably inserted into the guide hole 711. 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 powered on, 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.
