A lifting electromagnet device for lifting vertical steel coils with non-contact electric control

Abstract

The invention provides a lifting electromagnetic device for performing contactless electronic control lifting and transporting on vertical-type steel coils. The lifting electromagnetic device comprises a main body part and an electronic control part; the main body part consists of a yoke plate, a shell, through shaft movable magnetic poles, coils, concentrating flux plates, a support plate and a junction box body; the upper part of the yoke plate is provided with a plurality of square holes according to the sizes of spacing blocks on the through shaft movable magnetic poles; a through shaft mode is adopted for connection and installation of the through shaft movable magnetic poles; the plurality of through shaft movable magnetic poles are distributed in a 'plum blossom petal' structure and act as coil iron cores, and a layer of concentration flux plates are surrounded at the periphery of the coil iron cores so as to form trapezoidal frames; each trapezoidal frame corresponds to a coil; the coils are made of two-glass-fiber enamel-cover flat aluminium wire materials; after the coils wind around the concentration flux plates, insulation materials are arranged on the outer periphery in a paving manner, so that multiple problems of insufficient electromagnetic suction force, over-low safety coefficient and the like which are caused by adverse factors such as relatively high steel coiled tower shape, severe environment temperature, and over-high coil temperature rise are solved.

Problems solved by technology

However, there are various kinds of hoisting materials at the production site, and the transportation conditions at the hoisting site are different.

For example, the production of steel coils is involved in the port, steel and other industries. Sometimes it is often necessary to lift steel coil materials at high temperature. Conventional vertical lifting often causes the magnetic field to gradually weaken due to the high temperature rise of the electromagnet coil and poor heat dissipation. , so that the coil is burned, and the weight of this type of electromagnet is relatively large, resulting in waste of magnetic field and high cost

In order to overcome the problems of existing technologies, researchers often slightly change the magnetic circuit design and heat dissipation in vertical lifting, but the industry still cannot get rid of the above difficulties, and also faces the problems of rising temperature and weak magnetic field; Ampere-turns are used to solve the weakening of the magnetic field, but at the same time increase the energy consumption and self-weight of the coil, and most electromagnets cannot better solve the tower shape of the steel coil and the equipment damage caused by contact or collision

[0003] At the same time, traditional electromagnetic lifting equipment has four major problems in industrial applications. These four problems have always been the problems faced by lifting electromagnets for steel coils: (1) The tower shape of steel coils makes the magnetic field unable to be fully utilized; (2) ) The magnetic poles of the electromagnet are damaged beyond repair during the long-term contact with the material; (3) The temperature of the steel coil is high, the temperature of the coil rises quickly, and the heat dissipation is slow; (4) The special DC circuit of the electromagnet causes the DC components in the control cabinet to burn out due to overcurrent Does not work with the device
