Lifting electromagnet for steel pipe

Abstract

The invention relates to a trolley steel tube bundling hoisting electromagnet. The hoisting electromagnet comprises one or more actuating coil and corresponding iron core, each actuating coil and the corresponding iron core forming into a small U shape electromagnet, with the iron core being the magnetic yoke with both ends fixed to two supporting plates, whose bottom fixed with several flexible magnets, whose top end being fixed, bottom dripping loosely, flexible magnet pole sticking out the said support face, with length equal or bigger than hoisting max. steel tube radius, distance between the outmost flexible magnetic poles of two support plates less than the min. steel tube bundle, with the surface coated with a layer of diamagnetic material. It can trolley the steel tube bundle with reliability, high working efficiency and low energy consumption.

AI Technical Summary

Problems solved by technology

[0002]Currently, steel pipe manufacturers use steel wire ropes to hoist bundled steel pipe bundles, and then use driving hooks to hook the steel wire ropes for hoisting. The hanging steel wire rope carries the weight of the entire bundle of steel pipes during hoisting. During the hoisting process, hanging and unhanging the steel wire rope takes up a lot of time, and the operation is very inconvenient and the work efficiency is very low.

In order to improve efficiency and facilitate operation, it is natural to consider using lifting electromagnets to lift steel pipe bundles. However, the existing lifting electromagnets all encounter the same problem when lifting steel pipe bundles, because the contact between the magnetic poles and steel pipe bundles is very small. Bad, the magnetic potential drop is very large, and the diameter of the steel pipe bundle is generally large, and the lifting electromagnet can only make a few steel pipes on the upper surface of the steel pipe bundle receive the magnetic force, and the rest of the steel pipes are all hung by the bundled steel belt. The strapping steel strap is easy to break

Therefore, it is generally believed that the lifting electromagnet is not suitable for lifting steel pipe bundles.
