The application of permanent magnet chuck in the industry:
In the production practice of lifting work, lifting equipment generally can not end the automatic operation, especially the extraction equipment, and electromagnets, permanent magnets, hooks and other lifting heavy objects are widely used before the mouth. According to the production reflection and field application inquiry, it is found that there are some defects in the above equipment.

Common technical problems of permanent magnet chuck:
Safety and energy saving technical problems: the use of electromagnets to lift heavy objects, there must be a power supply, when the lack of power or sudden power failure, taking equipment can not operate normally, and even may constitute a safety accident, it is not easy to underwater and other special operating environment, its safety, reliability is not high, the use of conditions are limited.

Technical problems of automatic loading and unloading: When using the general permanent magnet magnet iron to lift heavy objects, because the magnetic core can not automatically move, the magnetic circuit is always in the registration or short connection situation, the suction is always in the suction or discharge situation, in the automatic transformation process of the end of the discharge and suction action, it must rely on external forces, operation auxiliary demagnetization equipment to end the hard separation, resulting in sheet metal deformation can not be lifted.

Technical problems of special operations: the use of hooks to lift heavy objects requires heavy lifting lifting, in some special and dangerous operating occasions, because of the harsh environment, manual lifting lifting hook is difficult and unsafe. Therefore, the lifting work urgently needs a fully automatic permanent magnet lifting crane.

It can be seen that the primary problem in the traditional lifting and hoisting is that it is impossible to end the problem of humanized efficient and safe operation.

Permanent magnet Jack lifting solutions:
Recently, the lifting technology department announced the automatic magnetic hoist. The magnetic crane can liberate the operator in special and dangerous working occasions, and has significant advantages such as high efficiency and energy saving, automatic loading and unloading, and safe operation.

The automatic magnetic crane mainly solves the two major problems of power engine and automatic lifting in technology. Its structure is divided into two parts: lifting and control. Among them, the lifting part is a group of rod organization with permanent magnet hoist as the primary lifting part. The control part is a composite device composed of power supply, remote control receiver and circuit board.

According to the structure principle of magnetic sucker, the structure of magnetic core and magnetic sucker is planned. The magnetic core is composed of magnetic steel and magnetic insulation material, and is installed in a magnetic box of magnetic insulation material, and a magnetic box push-foot is fixed on the surface of the magnetic box. The magnetic sucker is composed of Q235 and magnetic insulation material, and is fixed as a whole with the shell, the shell is a magnetic insulation material, through the relative movement of the magnetic core and the magnetic sucker, the magnetic circuit is registered (suction) and short (discharge) two cases.

As for the lifting rod, it is planned and manufactured in strict accordance with the principle of mechanics, so it is no longer detailed here.

永磁吸盘全自动磁力吊特点：

(1) Automatic magnetic crane is composed of strong magnetic nickel iron boron magnetic circuit system, strong magnetic, by lifting and lowering the derrick, the full use of permanent magnet chuck jack self-weight automatic control magnetic circuit registration and shorting, to achieve the end of the automatic operation of the mouth. The maximum lifting weight planned by the model is 20kg and different lifting weights are achieved by increasing or decreasing the number of magnetic blocks.

(2) Automatic permanent magnet jack can lift block, cylindrical and other shapes of magnetic conductive materials, suitable for lifting plates, especially thin plate lifting.

(3) During the lifting process, the magnetic core suction and discharge action can be automatically and reliably ended.

(4) The structure is light and safe, the operation is simple and convenient, and the adsorption force is strong.

(5) The control part is planned to meet the positive and negative operation requirements of the two motors, and can cooperate with the lifting part to end the automatic lifting process, and has outstanding safety protection performance.

Through repeated field test, the permanent magnet jack can automatically end the suction and discharge action, which has high practical production and application value.

The innovation of permanent magnet chuck automatic permanent magnet crane:

(1) The movement of the magnet core of the automatic permanent magnet jack requires neither electricity nor manual, and completely uses the self-weight of the permanent magnet jack and the mechanical automatic lifting organization to end.

(2) Suitable for underwater and field operations, and can ensure that the thin sheet that is not easy to transfer is not deformed.

(3) The selection of high-energy magnetic materials, so that it is smaller, lighter weight, but powerful magnetic force. The base eliminates the influence of remanence and magnetic leakage.

(4) The wonderful use of mechanical and electrical integration to end the automatic lifting process, reduce labor intensity, make the operation more simple and safe.

Fully automatic magnetic lifting, show one’s skill in the place of distress, designed to solve the problem of safe and efficient operation, energy saving automatic lifting.
