Abstract
The utility model discloses a special electromagnet of coil of wire circle handling, reaching to connect in parallel including the yoke board and fixing two iron cores in the yoke board lower part, there is excitation coil in every iron core outside all winding, and two excitation coil's polarity is opposite, side and the following of every excitation coil are equipped with the protection shield and do not have the magnetism layer board, no magnetism layer board two -layer for from top to bottom, be between the two -layer no magnetism layer board with the communicating heat dissipation wind channel of air. Adopt above -mentioned structure, the heat of coil of wire circular radiation can be blocked to bottom nos magnetism layer board, and during the heat that excitation coil produced can be in time gives off the air through the wind channel of dispelling the heat for the inside temperature rise of electro -magnet reduces, is keeping under the same coil number of turns circumstances, and the temperature rise has reduced about 40%, guarantees the electro -magnet and can work for a long time. Simultaneously, because the temperature rise reduction for the electro -magnet can use the excitation coil that the number of turns is bigger, makes suction stronger, has improved operational capability.
Description
One, technical field
The utility model belongs to electromagnet technical field, is specifically related to the special lifting electromagnet of a kind of coil of wire circle handling.
Two, background technology
Coil of wire circle is one of topmost raw MAT'L of construction trade, is widely used in the industrial civil building fields such as real estate, transmission mast for power, long-span roofing plate, port and pier, power station.Along with the technical innovation of metallurgy industry, the capability and performance of dish circle is also gradually improved, often lifting electromagnet is commonly used in handling, the transhipment of coiling circle, usually there is following problem when handling in lifting electromagnet in the past: handling high-temperature steel wire tray bowlder, the temperature of dish circle itself is very high general at 200 DEG C-400 DEG C, if this type high temp dish of the long-time handling of electromagnet circle, the heat of dish circular radiation is absorbed by electromagnet itself greatly, and then cause electromagnet temperature rise too high, suction declines, even burn excitation coil, can not work long hours.
Three, summary of the invention
It is simple, reasonable in design that the purpose of this utility model is to provide a kind of structure, effectively can solve handling height Winchester disk bowlder, the special lifting electromagnet of coil of wire circle handling of the electromagnet temperature rise occurred, the problem such as can not to work long hours.
For achieving the above object, the technical solution adopted in the utility model is: this electromagnet comprises two iron cores that yoke plate and parallel connection are fixed on yoke plate bottom, and be all wound with excitation coil outside each iron core, the polarity of two excitation coils is contrary; The side of each excitation coil and be provided with fender below and without magnetic supporting plate; Be characterized in: described is two-layer up and down without magnetic supporting plate, two-layer without the heat dissipation wind channel for communicating with air between magnetic supporting plate.
Adopt said structure, the bottom heat that can block coil of wire circular radiation without magnetic supporting plate, and the heat that excitation coil produces can be dispersed in air by heat dissipation wind channel in time, the temperature rise of electromagnet inside is reduced, in the same coil turn situation of maintenance, temperature rise reduces about 40%, guarantees that electromagnet can work long hours.Meanwhile, because temperature rise reduces, make electromagnet can use the excitation coil that the number of turn is larger, make suction stronger, improve working ability.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Five, detailed description of the invention
As shown in Figure 1, the utility model comprises two iron cores 2 that yoke plate 3 and parallel connection are fixed on yoke plate bottom, and be all wound with excitation coil 1 outside each iron core 2, the polarity of two excitation coils 1 is contrary.The side of each excitation coil 1 and be provided with fender 4 below and without magnetic supporting plate 8.Described is two-layer up and down without magnetic supporting plate 8, two-layer without the heat dissipation wind channel 6 for communicating with air between magnetic supporting plate 8.The height of this heat dissipation wind channel 6 is 30-40mm.Be provided with pole shoe 5 in each iron core 2 bottom, this pole shoe 5 bottom is arcuate structure.This kind of arcuate structure can coincide very well with steel wire disk external diameter, increases the area of contact of electromagnet and coil of wire circle, avoids stressed concentrated damage steel wire disk.
As Fig. 2, be provided with arc magnetic conduction infill panel 7 in the both sides of iron core 2, iron core 2 and arc magnetic conduction infill panel 7 combined and forms the low bulge shape structure in middle high both sides.This kind of bulge shape structure, after excitation coil 1 coiling can not with iron core 2 in the middle part of there is larger gap.Like this, after later stage electromagnet perfusion, what can not cause because of electromagnet cold and hot expands with heat and contract with cold, and makes excitation coil 1 section produce crack, and then causes electromagnet local temperature too high, cause electromagnet to scrap.
