Description

Technical Field

[0001] The utility model relates to the technical field of electromagnet maintenance, in particular to an electromagnet coil removal device. Background Technique

[0002] An electromagnet is a device that generates electromagnetic force when energized. A conductive winding matching its power is wound around the outside of the iron core. This current-carrying coil has magnetism like a magnet. We usually make it in a bar shape or a horseshoe shape to make the iron core easier to magnetize. In addition, in order to make the electromagnet demagnetize immediately when powered off, we often use soft iron or silicon steel materials with faster demagnetization to make it. Such an electromagnet has magnetism when energized and the magnetism disappears when powered off. Electromagnets have extremely wide applications in our daily life, and the invention of it has also greatly improved the power of generators.

[0003] At present, when the existing electromagnet coils are recycled and maintained later, the removal of the electromagnet coils is required. In recent years, with the increase of the process and the usage amount, the volume and weight of the electromagnets are gradually increasing. When the existing electromagnets are disassembled, most of them are carried out by a welder who welds brackets on the electromagnet shell in advance, and then uses a jack to support the brackets to remove the coils. This usage method not only damages the electromagnet shell during welding, but also has a long welding time, is easy to waste manpower and material resources, and has a poor safety factor.
