Universal crane electromagnet for vertical and horizontal steel coils

Abstract

The invention discloses a lifting electromagnet, especially a universal lifting electromagnet for handing horizontal and vertical steel coil. The lifting electromagnet is U-shape electromagnet. There is an arc at the middle segment on the length direction at the lower end face of magnetic pole. There is an arc groove with the same curvature of the arc in the arc. The arc groove has no groove edge at the inner side of magnetic pole, namely only the arc groove has groove edge at the outer side. Soft magnetic tape is set in the arc groove. The soft magnetic tape at the inside of magnetic pole is level to the inside of magnetic pole. Two ends of soft magnetic tape are fixed with two ends of arc groove respectively and the soft magnetic is catenary suspension linear shape. The length of soft magnetic tape is equal to the length of arc groove and the top point is lower than the bottom face of magnetic pole. The height of groove edge of arc groove is equal to the thickness of soft magnetic tape. The distance of inner sides of two magnetic poles is smaller than the diameter of inner circle of steel coil slightly. The length of magnetic pole is larger than the chord length where the outside of magnetic pole is intersected with the steel coil. The invention not only hoists vertical steel coil but also hoists horizontal steel coil. The invention is provided with simple structure, stable work and light weight.

Description

technical field [0001] The invention relates to a lifting electromagnet, in particular to a lifting electromagnet for hoisting steel plate coils. Background technique [0002] At present, the hoisting of steel coils is generally divided into vertical and horizontal hoisting methods. The so-called vertical means that the axis of the steel coil is in a vertical state. The axis of the steel coil is horizontal, commonly known as horizontal steel coil or horizontal coil. At present, the hoisting of horizontal steel coils mainly uses special mechanical spreaders, and some enterprises use electromagnets for hoisting, and vertical steel coils also mostly use electromagnets for hoisting. Due to the different ways of lifting vertical steel coils and horizontal steel coils, the electromagnet must be able to lift both vertical steel coils and horizontal steel coils. Generally, the movable magnetic poles are assembled on the fixed magnetic poles to realize its function, but due to the l...

Problems solved by technology

Due to the different ways of lifting vertical steel coils and horizontal steel coils, the electromagnet must be able to lift both vertical steel coils and horizontal steel coils. Generally, the movable magnetic poles are assembled on the fixed magnetic poles to realize its function, but due to the limitation of the movable magnetic poles The stroke is relatively large, which makes the structure of the existing general-purpose electromagnet capable of lifting vertical steel coils and horizontal steel coils too complicated, with a large self-weight, and the movable magnet is extremely prone to failure, so this general-purpose electromagnet is rarely used. Iron, still basically use vertical steel coil electromagnet and horizontal steel coil electromagnet to lift vertical steel coil and horizontal steel coil respectively
