Description

Technical Field

[0001] This utility model relates to the field of electromagnet hoisting technology, and in particular to an auxiliary device for electromagnet hoisting. Background Technology

[0002] In industrial production, electromagnets are widely used in heavy-duty lifting operations in industries such as steel and machinery due to their convenient adsorption and release characteristics. However, existing electromagnet lifting equipment has significant drawbacks in actual operation: when the lifting machine lowers the electromagnet, the lifting cable lacks a stable guiding and fixing structure, making it susceptible to external forces during descent. This causes the connection socket between the lifting cable and the electromagnet's power supply port to bear additional tension, leading to electromagnet tilting. The tilt of the electromagnet directly causes the cable reel inside the lifting machine to become misaligned, resulting in severe friction between the misaligned reel and the inner wall of the casing, as well as the lifting cable. On the one hand, long-term friction severely wears down the outer protective layer of the lifting cable, significantly shortening its lifespan and increasing equipment maintenance costs and safety hazards. On the other hand, the connection socket to the power supply port, subjected to continuous additional tension, is prone to loosening, poor contact, or even detachment. This not only affects the continuity of lifting operations but may also cause the heavy object to fall due to a sudden power outage, posing a serious threat to the safety of personnel and equipment on site. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a safer and longer-lasting electromagnet hoisting auxiliary device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An electromagnet hoisting auxiliary device, the key features of which include a hoisting machine, a hoisting cable, a traction device and an electromagnet; The hoisting machine is connected to the hoisting cable via a fixing ring at the top of the traction device. The hook of the hoisting machine is connected to the top ring of the electromagnet. The hoisting cable is connected to the power supply port of the electromagnet via a connector at one end.

[0005] Preferably, the hoisting machine includes a hoisting cable, a hook, a cable reel, and a housing; the cable drives the hook to move through two cable reels; the cable reels are located inside the housing; and the hook is sleeved on a connecting rod between the two cable reels.

[0006] Preferably, the traction device includes a fixed plate, a traction plate, and a fixing ring; the fixed plate is positioned directly above the two cable reels, one end of the traction plate is bolted to the center of the fixed plate, and the connection between the traction plate and the fixed plate is located directly above the connecting rod between the two cable reels; the fixing ring is positioned at the other end of the traction plate; the fixing ring is a U-shaped ring with threads at both ends, and is fixed by bolts after passing through pre-set holes in the traction plate at both ends; the hoisting cable passes through the fixing ring and is fixed to the traction plate through the fixing ring.

[0007] Preferably, the electromagnet includes a main body, a power supply port, and a top ring; the power supply port is connected to the coil inside the main body.

[0008] The beneficial effects of adopting the above technical solution are as follows: This invention uses a fixing ring to limit and fix the hoisting cable. Combined with the force transmission between the traction plate and the fixing plate, the tension on the hoisting cable is precisely guided to the center of the cable reel, ensuring that the cable reel is always in a horizontal and balanced state. This avoids friction between the cable reel and the outer shell and the cable due to cable reel tilting, significantly reducing the wear of the hoisting cable and extending its service life. At the same time, it reduces the damage of the tension to the connection socket and the power supply port, reducing the risk of power outage.

[0009] This utility model achieves the function of tensile force transmission through a traction device. It has a simple structure, is easy to disassemble and assemble, facilitates subsequent inspection and maintenance, and can be directly installed on existing hoisting machines, which is convenient and quick.

[0013] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0014] An electromagnet hoisting auxiliary device includes a hoisting machine, a hoisting cable 8, a traction device, and an electromagnet. The hoisting machine connects to the hoisting cable 8 via the fixing ring 7 at the top of the traction device. The hoisting machine's hook 2 connects to the top ring 9 of the electromagnet. The hoisting cable 8 is connected to the power supply port of the electromagnet via a connector at one end.

[0015] When a hoist lifts an object using an electromagnet, during the descent of the hoist, the friction of the hoisting cable 8 causes a pulling force at the connection between the socket and the power supply port to pull the cable 8 down. In this environment, the pulling force at the connection between the socket and the power supply port causes the electromagnet to tilt, resulting in the cable reel 3 becoming skewed. The cable reel 3 and the outer casing 4 rub against the hoisting cable 8, causing wear and tear on the cable 8, greatly reducing its lifespan. Furthermore, the external force wear on the connection socket and the power supply port also reduces its service life.

[0016] The hoisting machine includes a hoisting cable 1, a hook 2, a cable reel 3, and a housing 4; the cable drives the hook 2 to move through two cable reels 3; the cable reels 3 are located inside the housing 4; the hook 2 is sleeved on the connecting rod between the two cable reels 3; The traction device includes a fixed plate 5, a traction plate 6, and a fixing ring 7. The fixed plate 5 is positioned directly above the two cable reels 3 and is connected by welding. One end of the traction plate 6 is bolted to the center of the fixed plate 5, and the connection point between the traction plate 6 and the fixed plate 5 is located directly above the connecting plate between the two cable reels 3. The fixing ring 7 is located at the other end of the traction plate 6. The fixing ring 7 is a U-shaped ring with threads at both ends. Both ends pass through pre-set holes in the traction plate 6 and are fixed by bolts. The hoisting cable 8 passes through the fixing ring 7 and is fixed to the traction plate 6 through the fixing ring 7. The electromagnet includes a main body, a power supply port, and a top ring 9. The power supply port is connected to the coil inside the main body.

[0017] The hoisting cable 8 is secured by the fixing ring 7, so that the tension originally generated at the connection between the connector socket and the power supply port is applied to the center of the connecting plate through the traction plate 6, and the tension is adjusted to the center of the cable reel 3. This ensures that the force on the hoisting cable 8 is always adjusted to the center of the cable reel 3 through the traction plate 6, ensuring the balance of the cable reel 3 and preventing friction caused by imbalance between the cable reel 3 and the hoisting cable 8. At the same time, the tension is transferred, reducing the tension at the connection between the connector socket and the power supply port. This is a weak point in the system connection and is prone to external damage and detachment. Reducing the tension improves the stability of the hoisting system.

[0018] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
