[0045] The tank cover 2 and the tank body 1 are fixed via a clamp mechanism 3 .

[0046] The above-mentioned tank body 1 and tank cover 2 are improved by using the original copper melting tank, a lifting disc 22 is arranged above the tank cover 2, and a vertical rib 23 structure is added at the bottom of the lifting disc 22 to increase the height of the lifting disc 22, so as to facilitate the automatic grabbing of the tank cover 2 by the sling, and a plurality of guide ribs 24 are arranged on the lower surface of the tank cover 2. In this embodiment, 6 guide ribs 24 are arranged, and the 6 guide ribs 24 are arranged with an inclined surface structure, so that when the tank cover 2 is opened and placed on the top of the tank cover 2 of another copper melting tank, the guide ribs 24 are engaged with the lifting disc 22 of the other tank cover 2;

[0047] At the same time, the heavy-duty fastening screw pressing structure on the original tank cover 2 is removed, and a fast and powerful clamping mechanism 3 is provided to fix the tank cover 2 and the tank body 1.

[0065] The two sling bodies 724 mentioned above move toward or in opposite directions through the driving of the bidirectional screw 723. When it is necessary to grab the copper melting tank cover 2, the two sling bodies 724 are close to each other. At the same time, a groove 726 is opened on the side where the two sling bodies 724 are close to each other. The size of the groove 726 is adapted to the size of the lifting disc 22, and the bottom of the groove 726 forms a support portion 727.

The drive motor of the hoist drives the bidirectional screw 723 to push the hoist body 724 to close to the circumferential side of the tank cover 2 lifting disc 22, and the tank cover 2 can be grabbed.

[0072] When the sling is lifted, the support part 727 structure formed on the bottom surface of the sling pulls the can lid 2 upward, and the movement of the large and small trolleys of the traveling crane drives the original can lid 2 to be transported. When the sling moves to the coordinate position just above the adjacent can lid 2, the sling descends, and the 6 groups of guide ribs 24 structure on the lower surface of the original can lid 2 are guided, positioned and fixed with the lifting disc 22 of another can lid 2, completing the stacking of the can lid 2. At this time, the copper melting tank of the original can lid 2 has been opened, and the sling automatically takes the copper coil for delivery. When the delivery is completed, the sling reaches the stacking position of the original can lid 2, grabs the original can lid 2 and moves it above the original copper melting tank. The sling automatically descends, and the original can lid 2 is guided and positioned by the conical guide seat 5 structure of the 6 groups of fast and powerful clamp mechanisms 3 of the original copper melting tank, and slides into the installation groove of the copper melting tank under the action of gravity, completing the capping process, and finally the can lid 2 and the copper melting tank are quickly pressed and fixed using the fast and powerful clamp handle 37 and the pressure rod 36.
