The first bearing seat 13 and the second bearing seat 15 are both fixedly mounted on the back surface of the base 1.

The top connecting piece 2 is used for connecting a hoisting mechanism, taking a cylinder as an example, and the end part of an output shaft of the cylinder is provided with connecting structures with different forms, such as: flange type, screw type, lifting lug type, etc., so the top connecting piece 2 can be a flange connecting piece or a screw connecting piece or a lifting lug connecting piece, which can be selected according to the requirement.

When the billet 16 is hoisted by using the billet hoisting tool provided by the embodiment of the utility model, taking the top connecting piece 2 connected with the cylinder as an example, the top connecting piece 2 is firstly installed on the cylinder (not shown in the figure). First, the first motor 6 and the second motor 10 are controlled to operate, and the first rotating arm 8 and the second rotating arm 12 are driven by the first motor 6 and the second motor 10 to rotate clockwise and counterclockwise respectively, so that the first rotating arm 8 and the second rotating arm 12 are opened (as shown in fig. 3). Then, the whole steel billet hoisting tool is driven to move downwards through the cylinder, so that the electromagnet 3 is in contact with the steel billet 16, the electromagnet 3 is opened to adsorb the steel billet 16, the whole steel billet hoisting tool is driven to move upwards through the cylinder, then the first motor 6 and the second motor 10 are controlled to respectively drive the first rotating arm 8 to rotate anticlockwise and the second rotating arm 12 to rotate clockwise, so that the first rotating arm 8 and the second rotating arm 12 are gradually clamped, the steel billet 16 is fixedly clamped through the first clamping block 9 and the second clamping block 14 (namely, in the state shown in fig. 1), the phenomenon that the electromagnet 3 loses magnetic adsorption force due to failure or other magnetic field influences is avoided, the steel billet falls in the moving process, and the injury is caused to personnel or other equipment, and therefore, the steel billet hoisting tool provided by the embodiment of the utility model has high safety performance. The top connecting member 2 in the embodiment of the present invention may be connected to not only the cylinder but also other lifting mechanisms such as a linear motor lifting platform, which is not particularly limited in the embodiment of the present invention.

It is to be noted that the lengths of the first and second rotating

arms

8 and 12 are equal and may be set to the size as shown in fig. 1, and the lengths of the first and second rotating

arms

8 and 12 are larger than the length of the a segment as shown in fig. 4. Wherein the length of the segment a represents the distance between the billet 16 and the lower end of the base 1 when the electromagnet 3 adsorbs the billet 16. The design can increase the length of the corresponding first clamping block 9 and the second clamping block 14, so that the billet hoisting tool can show good clamping force when facing billets with different thicknesses. Under the design of this kind of size, after electro-magnet 3 adsorbs steel billet 16, need drive steel billet lifting device through the cylinder and move up a section distance after, first swinging boom 8 and second swinging boom 12 press from both sides tightly gradually again to avoid pressing from both sides tight in-process and other steel billets or the ground production of treating the hoist and mount at first swinging boom 8 and second swinging boom 12 gradually and interfere. Because the distance that the cylinder drives the billet lifting tool to move upwards is usually not very long, even if the billet 16 falls due to losing the magnetic adsorption force at this time, the gravitational potential energy of the billet is limited, and the billet cannot be damaged.

Of course, embodiments of the present invention may be designed in another size instead of the size shown in fig. 4. Fig. 5 shows a front view of a steel billet lifting tool according to an embodiment of the utility model. As shown in fig. 5, the lengths of the first rotating arm 8 and the second rotating arm 12 are designed to be equal to the distance between the billet 16 and the lower end of the susceptor 1 when the electromagnet 3 attracts the billet 16. Namely a hoisting tool which is designed to be suitable for fixing steel billets of a certain type. Then, at this time, it is not necessary to gradually clamp the first rotating arm 8 and the second rotating arm 12 after the billet lifting tool is driven by the cylinder to move upwards for a certain distance. Under the condition of the size design shown in fig. 5, the first rotating arm 8 and the second rotating arm 12 can be gradually clamped while the steel billet hoisting tool is driven by the cylinder to move upwards, and after the steel billet hoisting tool is driven by the cylinder to move upwards for a certain distance, the first rotating arm 8 and the second rotating arm 12 just clamp the steel billet 16.
