Description

The permanent magnet hoisting electromagnet

One, technical field:

The utility model relates to a kind of permanent magnet hoisting electromagnet.

Two, background technology:

Present common electromagnetism class lifting electromagnet adopts iron core coil structure, coil electricity to inhale heavy, coil blackout and unloads heavily, in order to prevent in the handling of absorbate body, to have a power failure and cause safety misadventure, need install additional to have a power failure and protect magnetic power supplying system, control path complexity.There is following several problem in this class electromagnet: consumption of current is big, copper loss is big, iron and steel consumption is big, volume big, control panel is doted on greatly, manufacturing cost is high; And in order to prevent in the handling process, to have a power failure suddenly to smash equipment and jeopardizing personal safety, must install additional to have a power failure and protect the magnetic power supplying system, make that control circuit is complicated more, serviceability is poor.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of economize on electricity, material saving, little, the easy reliable permanent magnet hoisting electromagnet of control of volume.

The utility model adopts following technical scheme: a kind of permanent magnet hoisting electromagnet, form by lifting auxiliary equipment and electromagnet ontology, it is characterized in that: on electromagnet ontology, be provided with the automatically controlled distribution equipment of micro computer, reversible permanent magnet aluminium nickel cobalt, reversible excitation coil, magnetic conduction magnetic pole and permanent magnet nd-fe-b and magnetic assembly binding bolt are housed in the described electromagnet ontology to be formed, and the fixing magnetic assembly of perfusion sealing, described reversible permanent magnet aluminium nickel cobalt is set with reversible excitation coil outward, the permanent magnet nd-fe-b be contained in the magnetic conduction magnetic pole around.

The utility model is owing to having adopted automatically controlled distribution equipment of micro computer and reversible permanent magnet aluminium nickel cobalt, reversible excitation coil, and magnetic conduction magnetic pole and permanent magnet nd-fe-b have following advantage is arranged:

1, economize copper, economize steel, volume is little, in light weight.

2, have the complete safe reliability, the handling process need not the electric energy support, need not to worry unexpected the power failure and fall material, can definitely guarantee the safety of staff and equipment.

3, when suction or blowing short, separate unit suction of compole or blowing time below 220mS.

4, adopted the order power supply technique can many or separate unit control, improved the degree of utilization of control power supply.

Four, description of drawings:

Fig. 1 is a constructional drawing of the present utility model;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is a control circuit block scheme of the present utility model.

Five, the specific embodiment:

The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:

From Fig. 1, Fig. 2 as can be known, the utility model is made up of lifting auxiliary equipment 1 and electromagnet ontology 4, installed the automatically controlled distribution equipment 3 of the micro computer that protective device 2 is arranged additional on electromagnet ontology 4, reversible permanent magnet aluminium nickel cobalt 5, reversible excitation coil 6, magnetic conduction magnetic pole 7 and permanent magnet nd-fe-b 8 and magnetic assembly binding bolt 9 compositions are housed in the electromagnet ontology 4, and the fixing magnetic assembly of perfusion sealing, reversible permanent magnet aluminium nickel cobalt 5 is outer to be set with reversible excitation coil 6, permanent magnet nd-fe-b 8 be contained in magnetic conduction magnetic pole 7 around.

As can be seen from Figure 3, the automatically controlled distribution equipment 3 of micro computer is made up of ac power switch 15, voltage-stabilized power supply circuit 16, microprocessor microcontroller 18, forward and reverse excitation trigger circuit 17, forward exciting controllable silicon 20, reverse exciting controllable silicon 21, power output circuit, power light 12, suction indicator lamp 11, blowing indicator lamp 10, suction button 13, blowing button 14, and power output circuit wherein can adopt excitation source multichannel output distributor circuit 19.

Suction, the blowing work of the utility model control lifting electromagnet are as follows:

1, suction process

Behind the power turn-on switch 15, microprocessor microcontroller 18 is lighted suction indicator lamp 11 when pressing suction button 13, drive the output of excitation source multichannel and distribute road 19, forward and reverse excitation trigger circuit 17, trigger 20 conductings of forward exciting controllable silicon, electric current is exported the direct impulse electric currents by source switch 15 through forward exciting controllable silicon 20 and excitation source multichannel output distributor circuit 19, direct impulse electric current moment is during by reversible excitation coil 6, reversible permanent magnet aluminium nickel cobalt 5 two ends magnetic poles change, become the N utmost point by the S utmost point, magnetic conduction magnetic pole 7 is also along with variation, when magnetic conduction magnetic pole 7 and permanent magnet nd-fe-b 8 same polarities on every side, magnetic conduction magnetic pole 7 shows magnetic, to lifting deposits yields suction, this suction is maintained to the arrival of reverse impulse electric current.Direct impulse electric current width controlled in microprocessor microcontroller 18.When the program that arrives microprocessor microcontroller 18 during the designated time, microprocessor microcontroller 18 turn-offs forward and reverse excitation trigger circuit 17, turn-offs excitation source multichannel output distributor circuit 19, finishes one road electromagnet suction process.
