Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electromagnetic slings, in particular to a disk electromagnetic sling beam. Background Art
[0002] Electromagnetic lifters are widely used in the metallurgical industry. They operate based on the principle of electromagnetic induction, whereby current flowing through the coils within an electromagnet generates an electromagnetic force that attracts and lifts objects. When the electromagnet is powered, it generates a magnetic field that is transferred to the steel or other object being attracted, creating a magnetic attraction. When the electromagnet is powered off, the magnetic field disappears, and the object is released from the electromagnet.
[0003] During the lifting process, uneven force on the lifting beam is a common problem. At this time, it is very likely that only two electromagnets are under force, while the other two are under less force or basically under no force, causing the left and right sides of the lifting beam to tilt due to the uneven force. The tilt of the lifting beam is also likely to cause the hoisted object to fall, thereby increasing the risk during the work process.
[0004] Traditional threaded electromagnetic cranes are prone to shaking during the process of hoisting coils due to the flexible connection between the electromagnetic block and the lifting beam. The shaking can easily lead to unstable adsorption of the electromagnetic block, causing the coil to disintegrate or fall during the hoisting process, posing a safety hazard. Therefore, traditional threaded electromagnetic cranes are not suitable for hoisting coils. Utility Model Content

[0024] Example
[0025] like Figures 1 to 2 As shown, an electromagnetic hanging beam for a round coil includes a main beam 100, wherein a plurality of electromagnetic hanging assemblies 200 are installed at the bottom end of the main beam 100. In this design, four groups are provided, and the electromagnetic hanging assemblies 200 are symmetrically installed at the bottom of the main beam 100. The adsorption and hanging of the round coil are achieved by the electromagnetic hanging assemblies 200. It is worth mentioning that an electric control box 121 is provided on the side of the main beam 100. The electric control box 121 is electrically connected to the electromagnetic hanging assembly 200. The electric control box 121 is used to control the power on and off of the electromagnetic hanging assembly 200. The electric control box 121 is connected to an external power supply through a line.
[0026] Preferably, the top of the main beam frame 100 is symmetrically provided with several connecting shaft seats 300. In this design, four groups of the connecting shaft seats 300 are provided, and the connecting ends of the four groups of connecting shaft seats 300 are all facing the center of the main beam frame 100. A lifting arm 400 is rotatably provided on the connecting end of the connecting shaft seat 300, and the lifting arm 400 forms an angle less than 90° with the top surface of the main beam frame 100. A lifting ear mounting plate 600 is installed on the other end of the lifting arm 400 through a hinge support 500, and a lifting ear 700 is provided on the middle part of the lifting ear mounting plate 600. An elastic force-bearing component 800 is also provided on the middle part of the lifting ear mounting plate 600. During lifting, the elastic force-bearing component 800 is pressed down to hook the lifting hook onto the lifting ear 700. The reset elastic force-bearing component 800 surrounds the lifting hook to the lifting ear 700 to limit the rotation of the lifting hook on the lifting ear 700. When the main beam 100 is subjected to uneven force, the end subjected to greater gravity will pull the main beam 100 to tilt toward the end subjected to force. At this time, the conventional lifting hook will rotate on the lifting ear and the main beam 100 will tilt. However, in this design, due to the presence of the elastic force-bearing component 800 and the balancing structure (the vertical distance between the lifting arm 400 and the main beam 100 and the top connection point of the lifting arm 400 and the top surface of the main beam 100 forms a triangular stable structure), the rotation of the lifting hook is suppressed. At this time, the lifting hook transmits the force to the elastic force-bearing component 800 and the balancing structure to maintain the balance of the main beam 100 and prevent it from tilting. Moreover, since the lifting arm 400 and the elastic force-bearing component 800 are rigid structures rather than flexible, they can further ensure the balance of the main beam 100, ensure stability during the lifting process, and improve the safety of the lifting operation.
[0027] In some preferred embodiments, the main beam frame 100 is not a solid beam, and the main beam frame 100 includes an upper top plate 110, a rib plate 120 and a lower bottom plate 130. The rib plate 120 is vertically installed between the upper top plate 110 and the lower bottom plate 130, and is in a vertical relationship with the upper top plate 110 and the lower bottom plate 130 respectively. The connecting shaft seat 300 is installed on the upper top plate 110.
[0028] In some preferred embodiments, the ear mounting plate 600 is provided with a plurality of guide holes, and the elastic force-bearing component 800 includes a guide rod 810, a spring 820, a limit plate 830 and a baffle plate 840. The guide rod 810 is slidably arranged in the guide hole, and the limit plate 830 is provided on one end of the guide rod 810, and the baffle plate 840 is provided on the other end. The limit plate 830 is located below the ear mounting plate 600, and the spring 820 is sleeved and installed on the guide rod 810. One end of the spring 820 is connected to the bottom surface of the ear mounting plate 600, and the other end is connected to the limit plate 830. The ear 700 is installed at the center enclosed by the baffle plate 840. When preparing for lifting, first press down the enclosure plate 840 to expose the lifting ear 700, then hook the lifting hook onto the lifting ear 700, release the pressed enclosure plate 840, and under the elastic restoring force of the spring 820, the enclosure plate 840 is lifted up and enclosed around the lifting ear 700, while enclosing the lifting hook. When the main beam 100 is subjected to uneven force and the lifting hook wants to rotate on the lifting ear 700, the hook body of the lifting hook will abut against the enclosure plate 840 to achieve balance and prevent tilting.
[0029] In some preferred embodiments, the electromagnetic hanging assembly 200 includes a lower end ear plate 210, a connecting arm 220, an electromagnet connecting plate shaft seat 230, an electromagnet connecting plate 240 and an electromagnetic block 250, wherein the lower end ear plate 210 passes through the lower base plate 130 and is installed on the bottom of the upper top plate 110, the electromagnet connecting plate shaft seat 230 is installed on the electromagnet connecting plate 240, and the electromagnetic block 250 is installed on the bottom surface of the electromagnet connecting plate 240, and a pin hole is provided on the lower end ear plate 210, and the connecting arm 220 is connected to the lower end ear plate 210 at one end through a connecting pin 221, and is connected to the electromagnet connecting plate shaft seat 230 at the other end, wherein an electric control box 121 is provided on the rib plate 120, and the electric control box 121 is electrically connected to the electromagnetic block 250, and the electric control box 121 is used to control the power on and off of the electromagnetic block 250.
[0030] To sum up, the utility model provides a circular electromagnetic lifting beam, which utilizes the elastic force-bearing components and the balancing structure (the vertical distance between the lifting arm and the main beam frame and the connection point on the top of the lifting arm and the top surface of the main beam frame forms a triangular stable structure) to suppress the rotation of the lifting hook on the lifting ear, so as to maintain the balance of the main beam frame and prevent it from tilting, thereby ensuring stability and safety during the lifting process.
