[0025] The clamp is formed in a U-shaped structure by the connecting plate 4 and the limiting plate 5, facilitating the insertion with the end of the carbon electrode, saving the operation time and enabling the staff to more easily and efficiently complete the clamping work of the carbon electrode. After the clamp is installed at both ends of the carbon electrode, the electric push rod 16 operates to push the positioning plate 17 to move downward, and the downward moving positioning plate 17 can shrink the length of the connecting cable 3. After the length of the connecting cable 3 is shrunk, hoisting is carried out, eliminating the instability factor that may be caused by the overlength of the connecting cable 3, ensuring the stability of the connection between the clamp and the carbon electrode, and even if bumps or vibrations are encountered during hoisting, the stability of the carbon electrode can be maintained, avoiding the risk of falling or damage caused by unstable connection, and facilitating the stable performance of the hoisting work.

[0026] A control assembly is arranged between the first mounting frame 2 and the fixed plate 7, and is used to drive the fixed plate 7 to move up and down. The control assembly comprises a rotating shaft 10 rotatably connected to the inside of the first mounting frame 2, a gear 11 fixedly connected to the outside of the rotating shaft 10, a rack 8 movably connected to the inside of the first mounting frame 2 and in meshing connection with the gear 11, and a driving assembly for driving the rotating shaft 10 to rotate. One side of the first mounting frame 2 is fixedly connected with a second mounting frame 14. The driving assembly comprises a motor 15 fixedly connected to the inside of the second mounting frame 14, a worm 13 fixedly connected to the output shaft of the motor 15, and a worm wheel 12 fixedly connected to one end of the rotating shaft 10. The worm 13 is in meshing connection with the worm wheel 12.

[0027] When the motor 15 starts to drive the worm 13 to rotate, the rotating shaft 10 is driven to rotate through the worm wheel 12. When the rotating shaft 10 rotates, the gear 11 drives the rack 8 to move up and down, and then drives the fixed plate 7 to move up and down through the rack 8, so as to realize the lifting of the carbon electrode.
