Disk lifting electromagnet

Abstract

The invention discloses a hoisting electromagnet, especially a hoisting electromagnet for hoisting a rod stock. The hoisting electromagnet is U-shaped and comprises a plurality of exciting coils and iron cores composing a plurality of small U-shaped electromagnets; the iron core is the magnetic yoke of the electromagnet, two ends of the iron core respectively fixedly connect with two magnetic poles, the homopolar magnetic poles of the small U-shaped electromagnet connect together through a connecting board, the length direction of the magnetic pole is identical with the direction of the axialline of the rod stock, the conduction between two magnetic poles is the rod stock, and the magnetic line of force are distributed along the circumferential direction of the rod stock. The invention can safely and reliably hoist rod stocks, and has advantages of light weight, low power consumption and big attractive force.

Description

technical field [0001] The invention relates to a hoisting electromagnet, in particular to a hoisting electromagnet for hoisting a disc. Background technique [0002] With the widespread use of high-speed wire rod production units in my country's metallurgical industry, the production efficiency has been greatly improved. In order to improve the efficiency of lifting high-speed wire coils, a large number of lifting electromagnets are used. At present, several electromagnets are generally used for hoisting high-wire coils, and most of them are "E" type electromagnets. On the one hand, using several electromagnets to lift high-wire coils requires additional beams, which increases the traffic load. On the one hand, this electromagnet has some deficiencies such as self-heavy weight and less lifting capacity.

Chinese patent (Patent No. ZL200520051305.1) discloses an "Integral Lifting Electromagnet for Hoisting High Wire Discs". When the magnetic field passes through the air gap between the disk circle and the circle, the magnetic potential drop is relatively large, the power consumption is large, and the structure is relatively complicated, which is inconvenient for maintenance.
