Description
Technical field
The utility model relates to a kind of electromagnet, is specifically related to a kind of lifting electromagnet.
Background technology
Lifting electromagnet is as a device that can produce huge suction, and range of use is wider.The electric current that when work, operating voltage produces by coil resistance produces huge gravitation on magnetic pole, and meanwhile, electric current produces larger heat on the resistance of coil.If this heat does not distribute, temperature can raise gradually, can become greatly because calorific effect can cause the resistance of coil, and working current can reduce, and suction reduces.General magnet spool and iron core are wrapped up by shell, and inner heat is difficult for distributing, the continuous working of electromagnet, and the temperature rising of coil can cause electromagnet suction to decline, and insulation reduces, and even causes coil burnout, and material tenesmus, has an accident.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is to provide a kind of good heat dissipation effect and the good lifting electromagnet of insulation effect.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of lifting electromagnet, it comprises iron core, for two bearings of secured core, be sleeved on the coil rack on iron core, and be wound on the excitation coil on coil rack, two bearings are separately positioned on the two ends of iron core, excitation coil is outside equipped with housing, and housing is sleeved on iron core, is evenly provided with multiple radiating fins on the outside face of housing.
Wherein, on the end plate of housing both sides, all offer multiple breather ports.
Wherein, between coil rack and iron core, be provided with collet.
Wherein, between excitation coil and housing, be provided with insulating barrier.
Wherein, on each bearing, be provided with two and play flap seat.
(3) beneficial effect
Compared with prior art, the utility model is provided with radiating fin, has ensured the heat radiation of electromagnet, has ensured service life and the in-use performance of electromagnet, and can guarantee reliable, safe handling, increase work efficiency.

Fig. 1 is the Facad structure schematic diagram of the utility model lifting electromagnet.
Fig. 2 is the left side structural representation of the utility model lifting electromagnet.
Fig. 3 is the A-A generalized section of Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The Facad structure of the utility model lifting electromagnet as shown in Figure 1, its left side structure as shown in Figure 2, its cross-section structure as shown in Figure 3, this lifting electromagnet comprises iron core 1, for two bearings 2 of secured core 1, be sleeved on the coil rack 3 on iron core 1, and be wound on the excitation coil 4 on coil rack 3, two bearings 2 are separately positioned on the two ends of iron core 1, excitation coil 4 is outside equipped with housing 5, housing 5 is sleeved on iron core 1, is evenly provided with multiple radiating fins 51 on the outside face of housing 5, and this radiating fin 51 is one-body molded on housing 5; Wherein, this housing 5 is made up of high manganese steel.
On the end plate 53 of housing 5 both sides, all offer multiple breather ports 52, make the air conducting in excitation coil, improved the heat dispersion of excitation coil.
Between coil rack 3 and iron core 1, be provided with collet 6, this collet can be made up of the thermal insulation material such as asbestos, aluminium silicate.The heat that the setting of collet has avoided iron core to produce passes to coil, has ensured the normal use of coil, the service life of having improved electromagnet.
Between excitation coil 4 and housing 5, be provided with insulating barrier 8, improve the insulation effect of electromagnet, avoid other parts to produce magnetization, and affect the normal use of lifting electromagnet.
On each bearing 2, be provided with two and play flap seat 7, be convenient to the installation of lifting electromagnet.
The utility model is provided with radiating fin, has ensured the heat radiation of electromagnet, has ensured service life and the in-use performance of electromagnet, and can guarantee reliable, safe handling, increase work efficiency.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
