Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic suction discs, in particular to a large electromagnetic suction disc with an auxiliary clamping structure. Background Technique
[0002] A large electromagnetic suction disc is a device used to adsorb magnetic materials such as steel in lifting and handling operations. It generates a strong magnetic force through the electromagnetic principle to adsorb the magnetic material and hoist it to a designated position. This equipment is widely used in the loading and unloading operations of industries such as ports, freight yards, steel plants, and ships. When an electric current passes through the coil of the electromagnetic suction disc, a magnetic field is generated, thereby adsorbing the magnetic material. After the power supply is cut off, the magnetic field disappears, and the adsorbed material can be put down. Compared with traditional lifting methods, the electromagnetic suction disc can complete the operation faster. It adopts a strong excitation and non-contact silicon rectifier module control, without arc sparking, basically no faults, safe and reliable. High-quality materials and advanced designs ensure the long-term stable operation of the equipment.
[0003] When using a large electromagnetic suction disc, it is usually necessary to install the large electromagnetic suction disc on a lifting device, move the large electromagnetic suction disc to the top of the lifted material through the lifting device, turn on the power supply, so that the large electromagnetic suction disc generates a magnetic force to adsorb the material at the bottom of the large electromagnetic suction disc, and then control the lifting device to move the material to the target position.
[0004] However, for common large electromagnetic suction discs, when adsorbing small materials such as bolts and nuts, a large number of materials will be sucked up at the same time. The farther the material is from the large electromagnetic suction disc, the smaller the magnetic suction force it receives. There is a possibility of falling during the movement of the lifting device, which is likely to injure the staff or other equipment. In view of this, this application proposes a large electromagnetic suction disc with an auxiliary clamping structure. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figures 1 to 3 , a large electromagnetic suction disc with an auxiliary clamping structure, including a magnetic suction housing 1. Two mounting blocks 2 are fixedly installed on both sides of the magnetic suction housing 1. An auxiliary clamping component is rotatably installed between the two mounting blocks 2. Two mounting vertical plates 6 are fixedly installed on the top of the magnetic suction housing 1. A hydraulic cylinder 7 for driving the auxiliary clamping component to rotate is arranged on one side of the mounting vertical plate 6.
[0022] Among them, the auxiliary clamping assembly includes an L-shaped rotating plate 3 rotatably installed between two mounting blocks 2. A clamping base 4 is fixedly installed at the bottom of the L-shaped rotating plate 3. An auxiliary claw 5 is fixedly installed at the bottom of the clamping base 4. The claw teeth of the two auxiliary claws 5 are staggered with each other. The movable end of the hydraulic cylinder 7 is arranged at the top of the L-shaped rotating plate 3. When the hydraulic cylinder 7 retracts, it drives the L-shaped rotating plate 3 to turn outward, driving the two auxiliary claws 5 to open. When the hydraulic cylinder 7 extends, it drives the L-shaped rotating plate 3 to turn inward, driving the two auxiliary claws 5 to clamp toward the middle.
[0023] Meanwhile, two top ear plates 8 are fixedly installed on one side of the mounting vertical plate 6. The hydraulic cylinder 7 is rotatably installed between the two top ear plates 8.
[0024] Among them, two bottom ear plates 9 are fixedly installed at the top of the L-shaped rotating plate 3. The movable end of the hydraulic cylinder 7 is rotatably installed between the two bottom ear plates 9.
[0025] Secondly, an electromagnetic body 10 is fixedly installed inside the magnetic attraction housing 1. A power controller 15 is fixedly installed at the top of the magnetic attraction housing 1. A power cord 16 is fixedly installed on one side of the power controller 15. The power controller 15 controls the on / off of the electromagnetic body 10 to generate or cut off the magnetic force.
[0026] Meanwhile, two mounting side plates 11 are fixedly installed on the surface of the magnetic attraction housing 1 near the bottom. A fixing nut 12 is fixedly installed at the top of the mounting side plate 11.
[0027] Among them, an adjusting screw 13 is threadedly installed at the top of the fixing nut 12. One end of the adjusting screw 13 extending to the bottom of the mounting side plate 11 is rotatably installed with a separating plate 14. When it is necessary to release the material, since there may be residual magnetism on the magnetic attraction housing 1, resulting in some materials not falling, at this time, rotate the adjusting screw 13 to make the adjusting screw 13 move downward, push the separating plate 14 downward, so that the separating plate 14 is separated from the magnetic attraction housing 1, and the material loses magnetism.
[0028] Finally, a lifting lug 17 is fixedly installed at the top of the magnetic attraction housing 1. A steel chain 18 is rotatably installed inside the lifting lug 17.
[0029] When this embodiment is in use, after lifting the material, the auxiliary clamping assembly is controlled by the hydraulic cylinder 7. The hydraulic cylinder 7 extends, driving the L-shaped rotating plate 3 to turn inward, driving the two auxiliary claws 5 to clamp toward the middle, and wrapping the material between the two auxiliary claws 5 to prevent the material from falling during the lifting process.
