Problems solved by technology

But this kind of lifting electromagnet is that two adjacent electromagnetic units form a U-shaped electromagnet, so because the central electromagnetic unit has two adjacent electromagnetic units, the central electromagnetic unit and the two adjacent electromagnetic units on both sides The unit forms two U-shaped electromagnets, that is, the central electromagnetic unit is a part of two adjacent U-shaped electromagnets, and the electromagnetic unit at the end has only one adjacent electromagnetic unit, which can only form a U-shaped electromagnet; The ampere-turns of the two electromagnetic units at both ends are small, and the ampere-turns of the central electromagnetic unit are large. Obviously, the iron cores of the two electromagnetic units at both ends are smaller than the iron core of the central electromagnetic unit. As a result, the two The electromagnetic unit and the central electromagnetic unit are not interchangeable, which brings inconvenience to maintenance, and at the same time consumes a lot of energy and self-weight

Embodiment Construction

[0014] from figure 1 , figure 2 As can be seen, the U-shaped combined lifting electromagnet of the present invention includes an electromagnetic unit 1 and a yoke 2; the electromagnetic units 1 of the U-shaped combined lifting electromagnet are an even number, and at least four electromagnetic units 1 are arranged. Four electromagnetic units 1 are preferred. The coil of each electromagnetic unit 1 is mounted on the iron core 3, and the coil is packaged with a shell, and the circumferential shell 5 of the shell is not magnetically conductive. Stainless steel is preferably used as the circumferential shell 5 in the present invention. One end of the iron core 3 of the electromagnetic unit 1 is welded to the pole shoe 4, and the other end is fixedly connected to the yoke 2 with bolts, the axis of the iron core 3 is perpendicular to the yoke 2, and the iron core 3 is in good contact with the yoke 2; and from the yoke 2 ends, the magnetic polarity of the first electromagnetic uni...

Abstract

The invention discloses a U-shaped combined lifting electromagnet, which includes an electromagnetic unit and a magnetic yoke; the electromagnetic units are even in number, and there are at least four electromagnetic units; one end of the iron core of the electromagnetic unit is fixedly connected with the magnetic yoke, The axis of the iron core is perpendicular to the yoke; starting from the electromagnetic unit fixed at the end of the yoke, every two electromagnetic units form a U-shaped electromagnet, and the two adjacent electromagnetic units of two adjacent U-shaped electromagnets The magnetic polarity is the same; the electromagnetic unit and the yoke are connected by bolts. The invention has the characteristics of low energy consumption, light weight and convenient maintenance.

Description

technical field [0001] The invention relates to an electromagnet, in particular to a lifting electromagnet. Background technique [0002] In my country's iron and steel production process, lifting electromagnets are widely used to lift billets and steel plates. However, the hoisting electromagnets used for hoisting steel billets and steel plates, especially for hoisting thick steel plates, are generally E-shaped structures, but this structure has a high energy consumption and a large dead weight. At present, there is a lifting electromagnet that adopts a plurality of electromagnetic units fixedly connected under a yoke plate, which actually constitutes a plurality of U-shaped electromagnets, which is more optimized in terms of energy consumption and self-weight than the E-shaped structure. But this kind of lifting electromagnet is that two adjacent electromagnetic units form a U-shaped electromagnet, so because the central electromagnetic unit has two adjacent electromagnet...
