Abstract
The utility model relates to a high-temperature hoist permanent magnet which is suitable for high-temperature workpiece operation, comprising a housing, a driving device and a rotatable magnetic circuit. The high-temperature hoist permanent magnet is characterized in that the housing is provided with at least one magnetic cell which can form the rotatable magnetic circuit, and the magnetic cell comprises a rotatable upper composite permanent magnet, a fixed lower composite permanent magnet, and magnetic poles. A plurality of heat conducting holes are arranged on the magnetic poles, and a plurality of heat pipes are embedded in the heat conducting holes. The magnetic field are superimposed are counteracted through the change of the magnetic circuit, and the problems of the weight sucking or weight unloading of workpieces. Through three thermal designs which are heat insulation, heat conduction, and the heat dispersion of heat dissipation air duct and ventilating fans, the problem of heat demagnetization is effectively solved, which makes the high-temperature hoist permanent magnet can hoist high-temperature heat workpieces.
Description
The utility model relates to the weight-lifting equipment field, particularly relate to high temperature modification hoisting permanent magnet the high temperature workpiece operation.
At present, domestic metallurgy industry is general when the handling heated work pieces to use electromagnet, owing to do not have heat insulation and heat abstractor, the insulating barrier of magnet coil easily wears out and influences its service life, generally use just need carry out large repairs in 7～8 months, and consumption of current is big.For existing hoisting permanent magnet, owing to inhaled the workpiece temperature height, cause hot demagnetization and influence suction, also be not suitable for the high temperature workpiece operation.
The utility model purpose is to provide a kind of high temperature modification hoisting permanent magnet by the magnetic Circuit Design of novelty and thermal design, overcomes above-mentioned shortcoming and defect, solves hot demagnetization problem, makes the hoisting permanent magnet still can normal operation when the heated work pieces of 500～850 ℃ of handlings.
The technical scheme that is adopted that achieves the above object is: this high temperature modification hoisting permanent magnet, comprise housing, actuating device and rotatable magnetic circuit, be characterized in housing, being provided with at least a magnetic cell that forms rotatable magnetic circuit, magnetic cell is made up of rotating composite permanent magnet, following fixedly composite permanent magnet and the magnetic pole gone up, and has on the magnetic pole to be embedded with the heat pipe member in thermal hole and the thermal hole.
Accompanying drawing has provided embodiment of the present utility model.
Fig. 1 forms the magnetic cell organigram of rotatable magnetic circuit for this high temperature modification hoisting permanent magnet.
