Abstract

The utility model relates to a permanent-magnetic electromagnet. The permanent-magnetic electromagnet comprises an electromagnetic coil, permanent magnets and two magnetizers, wherein the electromagnetic coil is vertically arranged between the two magnetizers and comprises an iron core and a coil wound on the iron core, and the middle part of the iron core is provided with an upper-part permagnet magnet; the coil is electrified forwards or reversely; the coil and a lower-part permanent magnet arranged below the electromagnetic coil form an in-series magnetic field or an in-parallel magnetic field so as to complete material discharging or suctioning. The permanent-magnetic electromagnet has the advantages that the energy-saving effect is achieved, and the electric energy consumption is only below 1% of that of the ordinary hoisting electromagnetic block; the safety is reliable, fortuitous accidents on the ordinary hoisting electromagnet due to sudden power failure can be avoided, and the material discharging of the permanent-magnetic electromagnet due to fortuitous power failure can be avoided, so that the safety of workers and equipment can be absolutely guaranteed; the permanent-magnetic electromagnet has the performances that the weight is light, the structure is simple, the service life is long, the quality is reliable, the maintenance is not needed basically and the like; the permanent-magnetic electromagnet adopts a design idea combining a scientific electromagnetic technology, an automatic constant-current control technology and a unique magnetic-path design technology.

Description

Permanent magnet solenoid

Technical field

The utility model relates to weight-lifting equipment, refers in particular to a kind of permanent magnet solenoid.

Background technology

What common lifting electromagnet adopted is that lifting is carried out in the magnetic field that hot-wire coil produces, this electromagnet is complex structure not only, and consumed power is bigger, because play important a lot of peripheral control unit that has by electric energy, making provision against emergencies has a power failure causes contingency, so rely on the electromagnet of electric power lifting that significant limitation is arranged.

Summary of the invention

The purpose of this utility model is improved and is innovated at the shortcoming that exists in the background technology and problem, and a kind of not electricity consumption lifting is provided, and the permanent magnet solenoid of playing function conversion is inhaled in electricity consumption.

The technical solution of the utility model is a kind of permanent magnet solenoid that comprises magnet coil, permanent magnet and magnetizer of structure, wherein:

Magnet coil is upright to be loaded between two magnetizers, comprises iron core and the coil that is wound on the iron core, and is provided with the top permanent magnet in the middle of the iron core;

Described coil is forward or oppositely energising, constitutes series field or magnetic field in parallel with the bottom permanent magnet that is arranged on the magnet coil below, finishes blowing or suction work.

Advantage of the present utility model and beneficial effect:

1, the utlity model has very considerable energy saving, power consumption only is below 1% of common lifting electromagnetic block.

2, the utlity model has the failure-free safety, common lifting electromagnet is worried to cause contingency because having a power failure suddenly, and the utility model need not worried unexpected the power failure and blowing, can definitely guarantee the safety of staff and equipment.

3, the utility model is in light weight, simple in structure, long service life, reliable in quality, performance such as need not keep in repair substantially.

4, the utility model adopts the electromagnetic technique of science, the mentality of designing that automation constant current control technology and unique magnetic Circuit Design technology combine.

Fig. 2 is the utility model lateral plan.

The specific embodiment

By Fig. 1,2 as can be known, the utility model comprises magnet coil, permanent magnet and magnetizer 2, wherein:

Magnet coil is upright to be loaded between two magnetizers 2, comprises iron core 5 and the coil 1 that is wound on the iron core 5, and is provided with top permanent magnets 4 in the middle of the iron core 5;

Described coil 1 is forward or oppositely energising, constitutes series field or magnetic field in parallel with the bottom permanent magnet 3 that is arranged on the magnet coil below, finishes blowing or suction work.

Magnetizer 2 described in the utility model is fixed on iron core 5 both sides of magnet coil by bolt 6, and two magnetizers, 2 outsides also are provided with the hanger that hoist cable is installed.

Structure of the present utility model and principle of work:

The utility model is made up of bottom permanent magnet 3, magnetizer 2, magnet coil, top permanent magnet 4, wherein magnet coil comprises iron core 5 and coil 1, and coil 1 is vertically-mounted, is provided with top permanent magnet 4 in the middle of the iron core 5, magnetizer 2 is located at the both sides of coil 1, inhales the blowing function behind the coil two-way communication.

Oppositely switch on when magnet coil, making the magnetic field of top permanent magnet is direction in parallel with the magnetic direction of bottom permanent magnet, and two magnetizers are finished the suction function jointly; When the magnet coil forward is switched on, can make the magnetic field of top permanent magnet be the direction of connecting with the magnetic direction of bottom permanent magnet, two magnetizers oneself forms closed magnetic path, finishes the blowing function.

Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
