Description

The steel board lifting electromagnet

Technical field

The utility model relates to a kind of lifting electromagnet, especially relates to a kind of lifting electromagnet of handling sheet material.

Background technology

Template steel and slab are that iron and steel enterprise produces one of maximum steel products and freak oil, and these class steel generally adopt the lifting electromagnet handling.The steel board lifting electromagnet that uses is " E " type electromagnet substantially at present, comprise a yoke plate and three magnetic poles, the housing of its electromagnet is actually by four bigger block plates of physical dimension to be formed, the large usage quantity of steel, in addition, because its iron core generally has only one, sectional area is big and be rectangle in addition, thereby under same ampere-turn situation, the weight of excitation coil is bigger, manufacturing cost is higher, and maintenance is inconvenient.

The utility model content

In order to solve the deficiency in the above-mentioned technology, the purpose of this utility model is to provide a kind of steel plate consumption less, the steel board lifting electromagnet that manufacturing cost is lower and easy to maintenance.

In order to solve the problems of the technologies described above, the utility model steel board lifting electromagnet, structure is " U " shape electromagnet, comprises one or more excitation coils and cooresponding iron core, each excitation coil and cooresponding iron core are formed little " U " shape electromagnet; Iron core is the yoke of " U " shape electromagnet, and the two ends of iron core are connected with two stay bearing plates respectively, and the bottom surface of stay bearing plate is fixed with many flexible magnetic poles, and the upper end of flexible magnetic pole is fixed, and the lower end freedom is sagging; The same polarity stay bearing plate of each little " U " shape electromagnet links to each other by connecting panel.

As a kind of improvement of the utility model steel board lifting electromagnet, steel board lifting electromagnet structure is " U " shape electromagnet, comprises one or more excitation coils and cooresponding iron core; Iron core is the yoke of " U " shape electromagnet, and two stay bearing plates link to each other with the two ends of each iron core respectively, and each iron core is identical with the polarity of same stay bearing plate connecting place; The bottom surface of stay bearing plate is fixed with many flexible magnetic poles, and the upper end of flexible magnetic pole is fixed, and the lower end freedom is sagging.

The lower surface of flexible magnetic pole is a little less than the bottom surface of solenoid housing.Flexible magnetism is the metallic cable of magnetic conduction very.This structure can guarantee flexible magnetic pole and fine contact of smooth steel plate of being hung.

The utility model adopts " U " shape electromagnet structure, and the tool iron core is the yoke of " U " shape electromagnet, saved steel plate as yoke plate, and magnetic pole is flexible magnetic pole, the optional old steel rope of this flexibility magnetic pole, thereby used steel plate is few, again owing to adopt a plurality of little iron cores, so same a.t., coil weight is light, overall low cost of manufacture.The utility model is convenient to maintenance especially, to first kind of the utility model,, only need the dismounting connecting panel that it is unloaded when certain little " U " shape electromagnet breaks down, change or do not change standby little " U " shape electromagnet, connect the function of promptly recovering lifting electromagnet with connecting panel again; And,, only need dismounting to comprise the excitation coil housing unit of coil and iron core when certain excitation coil breaks down to second kind of the utility model, change the function that auxiliary excitation solenoid housing assembly can recover lifting electromagnet.

Description of drawings

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

Fig. 1 is the scheme drawing of the utility model steel board lifting electromagnet of being made up of a plurality of little " U " shape electromagnet.

Fig. 2 is the A-A generalized section.

Fig. 3 is improved the utility model steel board lifting electromagnet scheme drawing.

Fig. 4 is that scheme drawing is looked on the left side of Fig. 1, Fig. 3.

The specific embodiment

From Fig. 1, Fig. 2, as can be known shown in Figure 4, the structure of the utility model steel board lifting electromagnet is " U " shape electromagnet.Comprise 3 little " U " shape electromagnet; Iron core 1 is the yoke of " U " shape electromagnet, excitation coil housing 4 is arranged on the iron core 1, the Circular Plate 5 of excitation coil housing 4 is a diamagnetic material, after excitation coil 10 is packed excitation coil housing 4 into, end plate is sealed in welding, again with the two ends of iron core 1 respectively with two stay bearing plates 2 by being weldingly connected, lower surface at each stay bearing plate 2 is fixed the upper end of many flexible magnetic poles 3 with card, the lower end freedom is sagging, flexible magnetic pole 3 is the old steel rope of Φ 12mm, little " U " shape electromagnet is formed than the low 10mm of bottom surface of solenoid housing in the lower surface of flexible magnetic pole 3; Same polarity stay bearing plate 2 with each little " U " shape electromagnet links to each other by connecting panel 8 then, connecting panel 8 is connected with stay bearing plate 2 usefulness bolts 7, and two terminations at two stay bearing plates 2 are welded an end plate 9 respectively, and this plate is a diamagnetic material, constitute big " U " shape electromagnet; Symmetric position above 4 hanger 6 uniform electromagnet is avoided connecting seam and is weldingly connected with stay bearing plate 2 upper surfaces.When the utility model steel board lifting electromagnet with contacted by the handling steel plate after, every flexible magnetic pole 3 contacts with steel plate, after the energising excitation, magnetic line of force enters steel plate through flexible magnetic pole 3 and form closed magnetic path, the steel plate of slinging under the effect of magnetic force.
