Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] The vertical and horizontal dual-purpose electromagnet structure includes a lifting structure, a top plate 3, a coil 4, and two magnetic pole discs 6; the lifting structure is fixed on the top plate 3, and is used for subsequent connection with a crane to lift the steel strip roll; coils 4 are respectively installed on both sides of the top plate 3, and the coils 4 are tightly attached to the top plate 3, and the two magnetic pole discs 6 are installed at intervals at the bottom of the top plate 3, specifically, they are arranged at intervals along the direction of the connection line of the two coils 4, and a plurality of active magnetic poles 7 are installed at intervals on the magnetic pole disc 6.

[0025] The active magnetic pole 7 contacts the end face or arc-shaped side face of the steel strip coil, and the coil 4 on one side, the magnetic pole master 6 on the same side, the active magnetic pole 7, the steel strip coil, the other magnetic pole master 6, the active magnetic pole 7, the coil 4 on the other side, the top plate 3, and the coil 4 on one side form a closed magnetic circuit. The magnetic field generated by the magnetic circuit adsorbs and fixes the steel strip coil, the magnetic pole master 6, and the active magnetic pole 7, making it easy to lift and move later.

[0026] When lifting the steel strip coil, the vertical and horizontal dual-purpose electromagnet structure places the magnetic pole disc 6 opposite to the end face of the vertical coil or the arc-shaped upper side face of the horizontal coil, so that the fixed magnetic pole contacts the end face of the vertical coil or the arc-shaped upper side face of the horizontal coil. When the electromagnet is working, the main magnetic flux generated by the electromagnet forms a closed magnetic circuit in the following order: one side coil 4 → the same side magnetic pole disc 6 → the movable magnetic pole 7 → the steel strip coil → the other side magnetic pole disc 6 → the movable magnetic pole 7 → the other side coil 4 → the top plate 3 → the return side coil 4. The generated main magnetic field fully magnetizes the steel plate within a certain depth of the steel strip coil, and generates a strong electromagnetic suction force to ensure the safe lifting of the steel strip coil.

[0027] In the utility model, the magnetic pole mother disk 6 has a downward mounting surface, the inner side of the mounting surface is processed into an arc shape, which increases the contact area and magnetic penetration depth during suction, lifting and horizontal winding, and ensures the effective transmission of magnetic force. The outer side of the mounting surface is a plane, and the active magnetic pole 7 is installed on the plane part. The interior of the magnetic pole mother disk 6 is provided with a countersunk hole, and the upper end of the active magnetic pole 7 is embedded in the countersunk hole and movably connected with the countersunk hole. The active magnetic pole can move up and down in the countersunk hole to overcome the tower shape of the vertical winding end face, increase the contact area during suction, lifting and vertical winding, and ensure the effective transmission of magnetic force; the two are combined to achieve a universal effect for vertical and horizontal winding; at the same time, the magnetic pole mother disk 6 and the active magnetic pole 7 are optimized and improved, the life of the active magnetic pole 7 is extended, and the production requirements of users are guaranteed.

[0028] In the present invention, the coil 4 comprises a housing 5 , on which a plurality of reinforcing heat sinks 8 are arranged at intervals, which not only increase the strength of the housing 5 , but also improve the heat dissipation effect of the coil 4 .

[0029] In the utility model, the lifting structure includes a lifting lug 2 and a chain 1. The lifting lug 2 is fixed on the top plate 3. In this embodiment, four lifting lugs 2 are provided according to the square structure of the top plate 3. The four lifting lugs 2 are respectively provided at the four corners of the upper end surface of the top plate 3 and arranged in an array. Of course, different numbers of lifting lugs 2 can be provided for top plates 3 of different shapes. The lifting lug 2 is provided with a lifting hole, and the chain 1 is connected to the lifting lug 2 through the lifting hole. The chain 1 is then connected to the hoisting machine to lift the steel strip coil.
