Abstract
The utility model discloses a lifting electromagnet with a ring-shaped magnet yoke. The lifting electromagnet comprises electromagnetic units and a ring-shaped magnet yoke, wherein at least three electromagnetic units are fixedly connected on the circumference of the magnet yoke uniformly; the axes of the electromagnetic units are vertical to the magnet yoke; the magnetic poles of the two adjacent electromagnetic units are different; the electromagnetic units are sealed by shells; the shells are not magnetic-permeable; and the electromagnetic units are connected with the magnet yoke by bolts. The lifting electromagnet has the characteristics of lower energy consumption, lighter dead weight and convenience in maintenance.
Description
Technical field
The utility model relates to a kind of electromagnet, especially relates to a kind of lifting electromagnet.
Background technology
In steel production in China technology, be extensive use of lifting electromagnet handling steel billet and steel plate.Handling steel billet and steel plate now, the lifting electromagnet that adopted of handling plate iron particularly, a large amount of circular configurations that adopt, but this traditional circular lifting electromagnet structure is because of there being the internal magnetic pole of a circle, it is around with excitation coil, adds the outer magnetic pole of a circle, and it is bigger to conduct oneself with dignity, and along with the diameter of circular lifting electromagnet increases, its deadweight increases very fast; And energy consumption is higher, and is difficult in maintenance.
Summary of the invention
In order to solve the deficiency in the above-mentioned technology, it is lower that the purpose of this utility model provides a kind of energy consumption, the lifting electromagnet lighter and easy to maintenance of conducting oneself with dignity.
In order to solve the problems of the technologies described above, the utility model annular arrangement yoke lifting electromagnet comprises electromagnetic unit, yoke; Yoke is an annular arrangement, and at least three electromagnetic units that circumferentially evenly are connected of yoke, the axis of electromagnetic unit is vertical with yoke, and the magnetic pole of adjacent two electromagnetic units is different; Electromagnetic unit is by body seal, and shell is magnetic conduction not.The other end and the pole shoe of the iron core of electromagnetic unit are connected.
The electromagnetic unit and the yoke bolt together of the utility model annular arrangement yoke lifting electromagnet.
Because the utility model annular arrangement yoke lifting electromagnet has adopted at least three electromagnetic units, evenly be connected in the circumferential of yoke, the different this structure of the magnetic pole of adjacent two electromagnetic units, each electromagnetic unit is identical, interchangeability is arranged, created condition for electromagnetic unit normalisation, seriation, be convenient to especially safeguard that certain electromagnetic unit has been broken, only need unload tie bolt, take off the damage electromagnetic unit, replacing with new electromagnetic unit can use, also very convenient to the maintenance that damages electromagnetic unit.In case and that traditional circular lifting electromagnet magnet coil damages its maintenance time is very long, and the dismounting coil quite bothers.
Because the closing of all electromagnetic unit core sections of the utility model annular arrangement yoke lifting electromagnet, the internal magnetic pole of traditional circular lifting electromagnet that should be identical with the handling ability or the sectional area of outer magnetic pole equate, so weight of the present utility model is lighter again.
And under the situation of same handling ability, generally speaking the a.t. of electromagnet should be identical, the diameter of the electromagnetic unit iron core of this structure is more much smaller than the internal magnetic pole diameter of existing traditional circular lifting electromagnet, so the used electromagnetic wire of electromagnetic unit coil of the present utility model must be shorter than the used electromagnetic wire of existing traditional circular lifting electromagnet coil, weight is also little.
Shorter because of the used electromagnetic wire of electromagnetic unit coil of the present utility model simultaneously than the electromagnetic wire of the coil of traditional circular lifting electromagnet, under the identical situation of electromagnetic wire sectional area, the resistance of the resistance ratio coil of the present utility model of the circular magnet spool of tradition is big, obtain same a.t., will increase voltage, energy consumption is higher; If under the situation that voltage equates, traditional circular electromagnets has only the electromagnetic wire of increasing sectional area, its resistance is equated with coil resistance of the present utility model, but will further strengthen deadweight, thus the energy consumption of raising handling appliance, so energy consumption of the present utility model is lower.
Thereby the utility model annular arrangement yoke lifting electromagnet to have energy consumption lower, the characteristics lighter and easy to maintenance of conducting oneself with dignity.
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 elevational schematic view of the utility model annular arrangement yoke lifting electromagnet structure.
Fig. 2 is the A-A cross-sectional schematic.
The specific embodiment
From Fig. 1, as can be known shown in Figure 2, the utility model annular arrangement yoke lifting electromagnet comprises electromagnetic unit 1, yoke 2; The electromagnetic unit 1 of annular arrangement yoke lifting electromagnet is at least three, preferred four electromagnetic units 1 of the utility model.The coil of the electromagnetic unit 1 of each is loaded on the iron core 3, uses the shell potted coil, and the peripheral envelope 5 of shell is magnetic conduction not, and the weak permeability magnetic material high manganese steel of peripheral envelope 5 usefulness of the present utility model is made.The one end welding pole shoe 4 of the iron core 3 of electromagnetic unit 1, the other end is connected in yoke 2 with bolt, and the axis of iron core 3 is vertical with yoke 2, and iron core 3 contacts with yoke 2 well; And make the magnetic pole of adjacent two electromagnetic units 1 different.Hanger in the upper surface welding of yoke 2.
