Description

Technical Field

[0001] The present invention relates to the technical field of electromagnets, and in particular to an anti-falling electromagnet. Background Art

[0002] Electromagnets, also known as lifting electromagnets and electromagnetic lifters, are mainly used in the steel, metallurgy, mining, machinery, transportation and other industries to lift magnetic materials such as steel. They are also used as electromagnetic manipulators to clamp magnetic materials such as steel, and are suitable for transporting cast iron ingots, steel balls and various scrap steel.

[0003] When the existing electromagnet is in use, it needs a sling to lift it for transportation. The sling is generally connected to the electromagnet through a hook. In order to facilitate disassembly, the hook generally has an opening to facilitate the installation or removal of the lifting ear, which causes a risk of falling off between the lifting ear and the hook. Especially when the hook is deformed under force for a long time, the lifting ear is more likely to fall off, causing the electromagnet to fall, posing a safety hazard. Therefore, the present invention proposes an anti-falling electromagnet to solve the problems existing in the prior art. Summary of the Invention

[0029] according to Figure 1 、 2 , 3, 4, 5, this embodiment proposes an anti-falling electromagnet, including a hanging plate 1, a suction plate 2 and an electromagnet 3, the electromagnet 3 is arranged between the hanging plate 1 and the suction plate 2, a lifting ear 4 is provided at the edge of the top of the hanging plate 1, and a hook portion is installed on the lifting ear 4, a sling 5 is connected to the hook portion, the hook portion includes a hook body 6, a first slide bar 7 and a second slide bar 8, the first slide bar 7 and the second slide bar 8 are respectively movably mounted on both sides of the interior of the hook body 6, and the lower ends of the first slide bar 7 and the second slide bar 8 both pass through the hook body 6;

[0030] A first gear 9 and a second gear 10 are rotatably mounted on the lower portion of the hook body 6. The diameter of the first gear 9 is larger than that of the second gear 10. A first meshing tooth 11 is mounted on the inner side of the first slide bar 7, and a second meshing tooth 12 is mounted on the inner side of the second slide bar 8, which is adapted to engage with the first gear 9. The first gear 9 and the second gear 10 are adapted to engage with each other, and a hook 13 is mounted on the lower end of the first slide bar 7. The meshing ratio of the second gear 10 and the second meshing tooth 12 is different from the meshing ratio of the first gear 9 and the first meshing tooth 11. When in use, it is connected to the lifting ear 4 through the hook portion. When lifting, the electromagnet 3 is forced downward, pulling the hook 13 and the first slide bar 7 downward. Through the linkage action of the first gear 9 and the second gear 10, and the adaptation action of the first meshing tooth 11 and the second meshing tooth 12, the second slide bar 8 is driven downward synchronously until the lower end contacts the hook 13, so that the first slide bar 7 and the second slide bar 8 are dynamically locked, sealing the opening to prevent the lifting ear 4 from falling off. Even after long-term use, the hook 13 is deformed downward to a certain extent, then the lower end of the second slide bar 8 is unlocked from the hook 13, and synchronously, the first slide bar 7 is also unlocked and continues to move downward. Through the action of gears and meshing teeth, the second slide bar 8 also moves downward synchronously until it contacts the hook 13 and is locked again.

[0031] A first guide rail 14 and a second guide rail 15 are respectively provided on both sides of the interior of the hook body 6. The first slide bar 7 is movably mounted on the inner side of the first guide rail 14, and the second slide bar 8 is movably mounted on the inner side of the second guide rail 15. When in use, the first guide rail 14 and the second guide rail 15 guide the movement of the first slide bar 7 and the second slide bar 8.

[0032] The hook body 6 is provided with a first guide slot 16 on one side of the front and rear ends. A first guide block 17 is provided above the front and rear ends of the first slide bar 7, which is adapted to fit within the first guide slot 16. A guide rod 18 is provided within the first guide slot 16, and the guide rod 18 movably extends through the first guide block 17. A first spring 19 is connected between the lower portion of the first guide block 17 and the lower portion of the first guide slot 16, and the first spring 19 is wound around the outer side of the guide rod 18. During use, the first guide block 17 and the first guide slot 16 cooperate to guide the movement of the first slide bar 7. To disassemble, simply place the electromagnet 3 on the ground to release gravity. The first spring 19 then pushes the first guide block 17 upward, causing the first slide bar 7 to rise, simultaneously raising the second slide bar 8. Because the diameter of the first gear 9 is larger than that of the second gear 10, the second slide bar 8 rises a greater distance due to different gear ring travels and meshing tooth ratios, leaving an opening between the lower end and the hook 13 for easy disassembly.

[0033] A second guide groove 20 is provided on the front and rear ends of the hook body 6, away from the first guide groove 16. A second guide block 21 is provided above the front and rear ends of the second slide bar 8. The second guide block 21 movably fits in the second guide groove 20. During use, the second guide block 21 fits in the second guide groove 20 to guide the movement of the second slide bar 8, thereby improving stability.

[0034] The hook 13 is provided with a splicing groove 22, and a splicing block 23 is provided below the second slide bar 8, and the splicing block 23 is adapted to the splicing groove 22. When in use, the splicing block 23 is adapted to the splicing groove 22, so that the lower end of the second slide bar 8 and the hook 13 are locked more firmly.

[0035] A connecting block 24 is provided at the upper end of the hook body 6 , and a hanging plate 25 is provided above the connecting block 24 , and the hanging plate 25 is connected to the sling 5 .

The inner slots 27 are arranged in multiple groups at equal angles around the center of the ear slot 26. A shaft plate 28 is movably provided inside the inner slot 27, and a roller 29 is rotatably provided inside the shaft plate 28. The outer side of the roller 29 is provided with an anti-slip layer 30. A first stopper 31 is provided at one end of the shaft plate 28, and a second spring 32 is connected to the first stopper 31 and one end inside the inner slot 27. After the hook portion is installed, the hook 13 passes through the ear slot 26. The roller 29 inside the ear slot 26 and the anti-slip layer 30 allow the hook 13 to rotate within the ear slot 26, but the sliding will encounter horizontal resistance, further preventing it from falling off. The second spring 32 can push the shaft plate 28 outward, causing the roller 29 to fit the sidewall of the hook 13.

[0037] An electric control compartment 33 is provided at a middle position above the hanging plate 1 , and a wire 34 is connected to the electric control compartment 33 , and the wire 34 is electrically connected to the electromagnet 3 .

[0038] Example 2

[0039] according to Figure 1 、 2 , 3, 4, and 6, this embodiment proposes an anti-falling electromagnet, comprising a hanging plate 1, a suction plate 2, and an electromagnet 3, wherein the electromagnet 3 is arranged between the hanging plate 1 and the suction plate 2, a lifting ear 4 is provided at the edge of the top of the hanging plate 1, and a hook portion is installed on the lifting ear 4, a sling 5 is connected to the hook portion, and the hook portion comprises a hook body 6, a first slide bar 7 and a second slide bar 8, the first slide bar 7 and the second slide bar 8 are respectively movably mounted on both sides of the interior of the hook body 6, and the lower ends of the first slide bar 7 and the second slide bar 8 both pass through the hook body 6;

[0040] A first gear 9 and a second gear 10 are rotatably mounted on the lower portion of the hook body 6. The diameter of the first gear 9 is larger than that of the second gear 10. A first meshing tooth 11 is mounted on the inner side of the first slide bar 7, and a second meshing tooth 12 is mounted on the inner side of the second slide bar 8, which is adapted to engage with the first gear 9. The first gear 9 and the second gear 10 are adapted to engage with each other, and a hook 13 is mounted on the lower end of the first slide bar 7. The meshing ratio of the second gear 10 and the second meshing tooth 12 is different from the meshing ratio of the first gear 9 and the first meshing tooth 11. When in use, it is connected to the lifting ear 4 through the hook portion. When lifting, the electromagnet 3 is forced downward, pulling the hook 13 and the first slide bar 7 downward. Through the linkage action of the first gear 9 and the second gear 10, and the adaptation action of the first meshing tooth 11 and the second meshing tooth 12, the second slide bar 8 is driven downward synchronously until the lower end contacts the hook 13, so that the first slide bar 7 and the second slide bar 8 are dynamically locked, sealing the opening to prevent the lifting ear 4 from falling off. Even after long-term use, the hook 13 is deformed downward to a certain extent, then the lower end of the second slide bar 8 is unlocked from the hook 13, and synchronously, the first slide bar 7 is also unlocked and continues to move downward. Through the action of gears and meshing teeth, the second slide bar 8 also moves downward synchronously until it contacts the hook 13 and is locked again.

[0041] An insert tube 35 is provided at the top edge of the suction plate 2, and an elastic rod 36 is provided at the bottom edge of the hanging plate 1. The elastic rod 36 is movably inserted into the insert tube 35, and a second stopper 37 is provided at the lower end of the elastic rod 36. A third spring 38 is connected between the second stopper 37 and the bottom of the insert tube 35. During use, the insertion of the elastic rod 36 into the insert tube 35 and the buffering effect of the third spring 38 facilitate shock absorption during material absorption, protecting the electromagnet 3 between the hanging plate 1 and the suction plate 2.

[0042] The anti-falling electromagnet is connected to the lifting ear 4 through the hook part. When lifting, the electromagnet 3 is forced downward, pulling the hook 13 and the first slide bar 7 downward. Through the linkage action of the first gear 9 and the second gear 10, and the adaptation action of the first meshing tooth 11 and the second meshing tooth 12, the second slide bar 8 is driven downward synchronously until the lower end contacts the hook 13, so that the first slide bar 7 and the second slide bar 8 are dynamically locked, sealing the opening to prevent the lifting ear 4 from falling off. When disassembling, it is only necessary to put the electromagnet 3 on the ground and release the gravity. Then, under the action of the first spring 19, the first guide block 17 is pushed up, causing the first slide bar 7 to rise and the second slide bar 8 to rise synchronously. Since the diameter of the first gear 9 is larger than that of the second gear 10, under the action of different gear ring strokes and meshing tooth ratios, the second slide bar 8 rises a greater distance, leaving an opening between the lower end and the hook 13, which is convenient for disassembly. After the hook portion is installed, the hook 13 passes through the ear slot 26. The roller 29 and anti-slip layer 30 within the ear slot 26 allow the hook 13 to rotate within the ear slot 26, but the sliding movement encounters horizontal resistance, further preventing it from falling off. Furthermore, the insertion of the spring rod 36 into the insert 35, combined with the cushioning effect of the third spring 38, facilitates shock absorption during material absorption, protecting the electromagnet 3 between the hanging plate 1 and the suction plate 2.
