Abstract

The utility model relates to a permanent-magnetic iron lifting device. The permanent-magnetic iron is driven by an electric motor which is assembled on the non-magnetic conduct frame through a shaft coupling screw rod to glide up and down along the open mouth of the lower end of the non-magnetic conduct frame and the pure iron pole shoe passages which are arranged on the both sides of the open mouth, and the movement distance of the permanent-magnetic iron is controlled by an upper and lower limiting switch. The permanent-magnetic iron lifting device uses the contact and the separation of the permanent-magnetic iron and the pole shoe to control the start and the stop of the lifting magnetic circuit, which reaches the purposes of lifting and unloading. Compared with the existing electric magnetic iron lifting devices, the utility model has the advantages of simple structure, low cost, convenient maintenance, power saving, etc.; the utility model can save large quantity of metal aluminum material, can hang and transport under the condition of no power without worry and does not need to be provided with spare UPS.

Description

A kind of permanent magnet weight-lifting equipment

The utility model relates to a kind of permanent magnet weight-lifting equipment, and this equipment can directly utilize permanent magnet magnetic force, lifting handling metal magnetic conducting material.

As everyone knows, permanent magnet has certain adsorption power to the metal magnetic conducting material, and using permanent magnet handling magnetic conductive metal material is something that people's dream has been asked.Utilize permanent magnet magnetic force can adsorb the material of constant weight, and with the material handling to assigned address.But lay down material and become a great problem.Just because of this, people directly utilize the dream of permanent magnet handling metal magnetic conducting material, are the something in people's illusion always.Can only make the very little handling appliance of some hoisting capacities by the indirect utilization permanent magnet at present, as a kind of hoisting sling of introducing in the CN2161591Y utility model patent specification sheets, this suspender is assemblied in permanent magnet in the disk body of a weight greater than its magnetic field suction, utilize permanent magnet to hold the constant weight material, handling then directly tangles the disk body; Permanent magnet and disk body chassis are broken away from, utilize the difference of disk body weight and magnetic force to reach the discharging purpose.Above-mentioned hoisting sling not only structure is very complicated, and equipment self weight is big, and manipulate also quite cumbersome, inefficiency.

The Nd-Fe-B rare-earth permanent magnet electricity-saved hoisting electromagnet introduced of CN2091850U for another example.This electromagnet is actual to be to utilize permanent magnet magnetic force as an attached suction, then need pass to counter-current in magnet coil during discharging, is used to overcome the adsorption affinity of permanent magnet to material.It is big that above-mentioned weight-lifting equipment exists existing electromagnet consumption of current equally, the manufacturing process complexity, and cost is high and need standby uninterruptible power, with shortcomings such as anti-power failures.

The purpose of this utility model be to overcome the deficiency of above-mentioned prior art and provide a kind of simple in structure, easy to use, energy-conservation, cost is low, can directly utilize the permanent magnet weight-lifting equipment of attraction of permanent magnet handling weight.

The utility model above-mentioned purpose is achieved by the following technical programs.

A kind of permanent magnet weight-lifting equipment is characterized in that this equipment connects permanent magnet by the motor that is assemblied on the non-magnetic guiding frame by the shaft coupling screw flight, and the pure iron pole shoe is equipped with in uncovered both sides, non-magnetic guiding frame lower end, is provided with the centre gangway that permanent magnet slides up and down between the pole shoe.This equipment is by the upper and lower slip of driven by motor permanent magnet, breaks away from pole shoe that pure iron is made or contact, unloads heavy or inhales heavy magnetic circuit keying purpose to reach control.When the needs lifting, motor moves down permanent magnet by its shaft coupling screw rod, inserts in the pole shoe centre gangway, and the permanent magnet pole surface is contacted with the both sides pole-shoe face respectively, and when needs unload when heavy, it is up to mention permanent magnet, makes it to break away from pole shoe to get final product.The utility model directly utilizes permanent magnet as a ponderomotive force, and the handling process operation freely, and gordian technique is to open and close by changing magnetic circuit, reaches to change by suction metalliferous material magnetic flow purpose.

Worn-out mouthful of above-mentioned permanent magnet and non-magnetic guiding frame lower end and the rectangular structure of pole shoe centre gangway transversal surface, be beneficial to permanent magnet about slippage freely.Above-mentioned motor is assemblied in non-magnetic guiding frame central upper portion position, and motor shaft coupling screw rod passes non-magnetic guiding frame centre hole and links to each other with the permanent magnet tapped bore.In order to control the permanent magnet shift length that rises and falls, the displacement position-limiting frame is housed on the permanent magnet, up or when falling to running into limit switch when permanent magnet, the control electric machine operation state.

The utility model directly utilizes permanent magnet control magnetic circuit conducting amount, reaches handling metallic material purpose, and not only mentality of designing is simple, and product structure is novel unique, and its cost reduces than existing electromagnet greatly with maintenance.The more important thing is and saved a large amount of electromagnet manufacturing materials and protected magneto-electric energy, do not need standby uninterrupted power supply.Said permanent magnet and pole shoe material in the utility model claims are not limited to so for example can adopt non-magnet material to substitute permanent magnet, adopt permanent magnet to substitute the pure iron pole shoe, in order to explain claim 1～4.

Introduce the utility model embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model integral installation distribution structure scheme drawing.

Fig. 2 inhales heavy industry for the utility model magnetic circuit is closed and makes schematic diagram.

Fig. 3 unloads heavy industry for the unlatching of the utility model magnetic circuit and makes schematic diagram.

In the present embodiment, permanent magnet 3 adopts high coercive nd-fe-b to make (magnetic flow reaches 13000 Gausses), and this permanent magnet center is processed with tapped bore.On the non-magnetic guiding frame 2 motor 1 is housed, its shaft coupling screw rod 8 passes tapped bore and is connected with permanent magnet 3.In the middle of two pure iron pole shoes 5 about non-magnetic guiding frame is equipped with for 2 times, pole shoe is permanent magnet 3 sliding channels 4, and permanent magnet 3 upper and lower displacements distance is determined by upper limit position switch 9 and lower position switch 6 by its position-limited rack 7.Motor 1 rotating both can drive permanent magnet 3 up or whereabouts.

Inhale when weighing, permanent magnet 3 is displaced downwardly in left and right sides pole shoe 5 centre gangways 4, and left and right sides bipolar shoe 5 is magnetized into N, the S utmost point respectively, constitutes C/LOOPs with absorbate 10, referring to Fig. 2 fundamental diagram.

Unload when weighing, permanent magnet 3 up disengaging left and right sides pole shoes 5, pole shoe 5 loses magnetic pole, can unload steel, referring to Fig. 2 fundamental diagram.

This equipment can be made different sizes such as 1T, 2T, 3T, 5T as required, and can adopt matrix to arrange and make big specification weight-lifting equipment.
