Description
Technical field
The utility model relates to a kind of lifting electromagnet, especially relates to a kind of lifting electromagnet of handling horizontal steel coils.
Background technology
The handling of coil of strip generally is divided into vertical and horizontal two kinds of handling modes, needs under many circumstances coil of strip is carried out horizontal handling, so-called horizontal be exactly that the axis of coil of strip is the level of state, being commonly called as this coil of strip is horizontal steel coils or horizontal roll.At present, the handling of horizontal steel coils mainly is to adopt the special-purpose machinery suspender, also has enterprise to adopt the electromagnet handling.The electromagnet that is adopted is generally " U " shape, utilize electromagnet to produce very powerful magnetic field, successively make its magnetic saturation air gap between penetrated bed more inwards from the top layer, cause its magnetic potential loss big, the interlayer limited amount that magnetic field can penetrate, therefore, it is the effects that are not subjected to magnetic field force that there are a lot of layers the centre of horizontal steel coils, be to hang in handling by tying up the steel band pocket, go out to tie up the phenomenon that the steel band fracture is loose and rolled up sometimes, thereby adopt electromagnet handling horizontal steel coils not general, especially use hardly in important working space and production staple product.This shows that the present electromagnet that adopts mainly exists the big energy consumption height of power of electromagnet, the problem that reliability is lower when roll of steel plate is crouched in handling.
The utility model content
In order to solve the deficiency in the above-mentioned technology, the purpose of this utility model is to provide the lifting electromagnet of the handling horizontal steel coils of the low and reliable operation of a kind of energy consumption.
In order to solve the problems of the technologies described above, the utility model horizontal steel coils lifting electromagnet is " U " shape electromagnet, the line of two magnetic poles and the axis normal of horizontal steel coils, a relative side of two magnetic poles respectively is a circular arc, each magnetic pole is similar " triangle " wide at the top and narrow at the bottom at the vertical surface of horizontal steel coils axis, these two circular arcs with matched by the cylindrical of the maximum specification horizontal steel coils of handling; Each magnetic pole respectively has a boss near two outsides at electromagnet middle part, and the outside of boss is fixed with many flexible magnetic poles, also is fixed with many flexible magnetic poles on two outsides of magnetic pole, and the upper end of every flexible magnetic pole is fixed, and the lower end freedom is sagging.
Distance between two outsides of each magnetic pole equals the minimum width of horizontal steel coils.Boss on two magnetic poles is near the diameter of bore of the distance between one side of electromagnet middle part less than horizontal steel coils; Distance between two boss outsides on each magnetic pole is greater than the width of maximum specification roll of steel plate for sleeping in.The lower end of flexible magnetic pole links to each other by flexible strand mutually.The length of flexible magnetic pole is greater than the radius of horizontal steel coils.Flexible magnetism is the magnetic conductive metal rope very.
Because the utility model has adopted flexible magnetic pole, during work, under the effect of excitation coil excitation, on two end faces attached to horizontal steel coils, every layer of coil of strip becomes flux path to flexible magnetic pole on two magnetic poles respectively, and magnetic line of force is by every layer of roll of steel plate, form C/LOOP, make every layer of roll of steel plate all be subjected to the effect of magnetic force, solved the not problem of magnetic field force induced effect of middle lower floor roll of steel plate, thus handling horizontal steel coils safely and reliably.Because the restriction of air gap ability handling between the necessary penetrated bed in magnetic field has been avoided in the variation of the utility model magnetic circuit, therefore saved the big energy of institute simultaneously, under the situation with equipower, handling ability of the present utility model improves 30% at least.

The specific embodiment
From Fig. 1-Fig. 4 as can be known, the utility model horizontal steel coils lifting electromagnet is " U " shape structure, preferred two excitation coils 5 are contained in respectively on the both sides iron core 3 of electromagnet, yoke and two iron cores 3 constitute " U " shape, excitation coil 5 is used the closing plate welded seal after being loaded in the solenoid housing, and the peripheral shell 4 of solenoid housing is diamagnetic plate; Magnetic pole 2 usefulness bolts and iron core 3 are connected; A relative side of two magnetic poles 2 respectively is a circular arc, and each magnetic pole 2 is similar " triangle " wide at the top and narrow at the bottom at the vertical surface of horizontal steel coils 8 axis, these two circular arcs with matched by the cylindrical of the maximum specification horizontal steel coils 8 of handling; Each magnetic pole 2 respectively has a boss 7 near two outsides at electromagnet middle part, the outside of each boss 7 is fixed with 10 flexible magnetic poles 1, also be fixed with 30 flexible magnetic poles 1 on two outsides of magnetic pole 2 respectively, the upper end of every flexible magnetic pole 1 is fixed with wire clips, the lower end freedom is sagging, and flexible magnetic pole 1 is a Φ 10mm steel rope.Distance between two outsides of magnetic pole 2 equals the minimum width of horizontal steel coils 8; Boss 7 on two magnetic poles 2 is near the diameter of bore 50mm of the distance between one side of electromagnet middle part less than horizontal steel coils 8; Distance between two boss 7 outsides on each magnetic pole 2 is greater than the width 200mm of maximum specification roll of steel plate 8 for sleeping in; The lower end of flexible magnetic pole 1 links to each other by flexible strand 9 mutually, thereby the relative position that guarantees every flexible magnetic pole 1 is constant; The length of flexible magnetic pole 1 is greater than the radius 50mm of horizontal steel coils 8.
From Fig. 5, as can be known shown in Figure 6, because the distance between two outsides of magnetic pole 2 equals the minimum width of roll of steel plate 8 for sleeping in, so regardless of width, the flexible magnetic pole 1 that is fixed on magnetic pole 2 outsides just contacts with the end face of roll of steel plate 8 for sleeping in when sagging naturally, naturally pass through the interconnect function of flexible strand 9, the lower end of many flexible magnetic poles 1 that are fixed on boss 7 outsides is also contacted with the end face of roll of steel plate 8 for sleeping in, this part flexible magnetic pole 1 is the loose last wide del of point down, and boss 7 is exactly the part of magnetic pole 2 in fact.When excitation coil 5 excitations, flexible magnetic pole 1 on two magnetic pole 2 outsides is respectively on two end faces attached to horizontal steel coils 8, the lower end of the flexible magnetic pole 1 on four boss 7 is at first respectively on two end faces attached to horizontal steel coils 8, and at this part flexible magnetic pole 1 under the effect of magnetic force from bottom to top on two end faces attached to the roll of steel plate 8 that crouches, till going out flexible magnetic pole 1 between boss 7 places and the topmost attachment point and being straightened, cause this part flexible magnetic pole 1 not contact with part middle level roll of steel plate, thereby guaranteed centering with the upper strata of horizontal steel coils 8, the magnetic field effect of lower floor's roll of steel plate.Because the conducting effect of flexible magnetic pole 1 makes every layer of roll of steel plate become flux path, magnetic line of force forms C/LOOP by every layer of roll of steel plate, makes every layer of roll of steel plate all be subjected to the effect of magnetic force, reduced magnetic field and passed the waste of power of interlayer air gap, and can safely and reliably horizontal steel coils have been sling and transport.
