Problems solved by technology
Because when the electromagnet is hoisting the horizontal steel coil, its magnetic pole is in contact with the outer circular surface of the horizontal steel coil. To make the magnetic pole contact with the outer circle of the horizontal steel coil better, the magnetic pole is used as an arc surface, but this structure is only for The effect of lying steel coils with one diameter specification is better, but the contact with other specifications and diameters is poor; and the use of movable magnetic poles can partially solve the problem of poor contact with lying steel coils with different specifications and diameters. The long stroke of the magnetic pole increases the volume of the electromagnet, which is heavy, consumes a lot of energy, and has a complex structure. Sometimes there are problems that affect the work such as the moving magnetic pole jamming

Embodiment Construction
[0013] As can be seen from Fig. 1-Fig. 4, the lifting electromagnet of the present invention is a "U" shaped electromagnet, and the excitation coil housing 6 is arranged on the iron core 2, and the ring plate of the excitation coil housing 6 is a magnetic-resistant material. After the excitation coil 5 is loaded into the excitation coil housing 6, the end plates are welded and sealed, and then the two ends of the iron core 2 are respectively connected to the two supporting plates 3 by welding; the lower end of each supporting plate 2 is clamped with a rope Fix the upper end of 100×10 flexible magnetic poles 1 that are uniformly densely distributed, and the lower end hangs freely. The cross-sectional area of all flexible magnetic poles 1 fixed on each side is equal to the cross-sectional area of iron core 2. The flexible magnetic pole 1 is a Φ10mm steel wire rope, and the flexible magnetic pole 1 The length of the length is greater than the distance from the bottom surface o...

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. diameter of the steel tube bundle, and the distance between flexible magnetic poles at both ends of the support plate less than the min. specification horizontal steel reel width. It has good contact between the magnetic poles and the horizontal steel reel, being able to hoist the trolley steel reel with simple structure, low energy consumption, light in weight and convenient in maintenance.
Description
technical field [0001] The invention relates to a lifting electromagnet, in particular to a lifting electromagnet for hoisting and transporting a lying steel coil. Background technique [0002] At present, the hoisting of horizontal steel coils mainly uses special mechanical spreaders, and some enterprises use electromagnets for hoisting. The electromagnet for hoisting the horizontal steel coil is generally an arc-shaped magnetic pole or a movable magnetic pole. Because when the electromagnet is hoisting the horizontal steel coil, its magnetic pole is in contact with the outer circle of the horizontal steel coil. To make the magnetic pole contact with the outer circle of the horizontal steel coil better, the magnetic pole is used as an arc surface, but this structure is only for The effect of lying steel coils with one diameter specification is better, but the contact with other specifications and diameters is poor; and the use of movable magnetic poles can partially solve ...
