Description

Technical Field

[0001] This utility model relates to the field of electrodes, and specifically relates to an electrode clamping and fixing ring. Background Art

[0002] The electrode is fixed by a spring. High temperature in the electric furnace can easily cause the spring to fail, resulting in unstable clamping of the electrode and easy slippage of the electrode. Content of the Utility Model

[0003] In order to overcome the above deficiencies, this utility model provides an electrode clamping and fixing ring.

[0004] The technical solution adopted by this utility model is as follows:

[0005] An electrode clamping and fixing ring includes an electrode column. There is a fixing ring on the outer side of the electrode column. Four hydraulic cylinders I and four hydraulic cylinders II are fixedly connected to the outer wall of the fixing ring. The hydraulic cylinders I and II are cross-distributed around the outer wall of the fixing ring. The output shafts of the hydraulic cylinders I and II both penetrate the inner wall of the fixing ring and are fixedly connected with clamping heads. The eight clamping heads abut against the outer wall of the electrode column.

[0006] The hydraulic cylinder I is remotely controlled, and the hydraulic cylinder II is manually controlled.

[0007] The beneficial effects of this utility model are as follows:

[0008] This utility model combines two control methods, namely manual control and remote control, which can not only meet the need for fine adjustment of the clamping force, but also achieve remote automated operation, improving the flexibility and adaptability of equipment use.

[0009] The design of the eight hydraulic cylinders provides sufficient supporting force and stability, ensuring the smooth movement of the electrode column during the process of lowering the electrode, and reducing potential risks caused by vibration or imbalance.

[0010] The clamping is reliable, and it is not easy for the electrode to fall off, causing the electric furnace to stop. This greatly reduces production energy consumption and improves production efficiency. Description of the Drawings

[0017] As Figures 1-5 shown: An electrode clamping and fixing ring includes an electrode column 1. A fixing ring 2 is provided on the outer side of the electrode column 1. Four first hydraulic cylinders 3 and four second hydraulic cylinders 4 are fixedly connected to the outer wall of the fixing ring 2. The first hydraulic cylinders 3 and the second hydraulic cylinders 4 are distributed crosswise around the outer wall of the fixing ring 2. The output shafts of the first hydraulic cylinders 3 and the second hydraulic cylinders 4 both penetrate through the inner wall of the fixing ring 2 and are fixedly connected to chucks 5. The eight chucks 5 abut against the outer wall of the electrode column 1.

[0018] The first hydraulic cylinders 3 are remotely controlled, and the second hydraulic cylinders 4 are manually controlled.

[0019] When the electrode clamping and fixing ring is in a non-working state, the chucks 5 of the eight hydraulic cylinders (four first hydraulic cylinders 3 and four second hydraulic cylinders 4) are all in a relaxed state, maintaining a certain gap with the outer wall of the electrode column 1 and not applying a clamping force.

[0020] When it is necessary to fix the electrode column 1, the operator manually controls the four second hydraulic cylinders 4, so that the output shafts of the second hydraulic cylinders 4 extend outwards, driving the chucks 5 to gradually approach and closely adhere to the outer wall of the electrode column 1. Since the clamping force of the second hydraulic cylinders 4 can be manually adjusted, the operator can adjust the magnitude of the clamping force according to needs to ensure that the electrode column 1 is firmly fixed.

[0021] When the electrode column 1 needs to be moved or lowered, the four first hydraulic cylinders 3 are started through the remote control system. The output shafts of the first hydraulic cylinders 3 also extend outwards, but their main purpose is to work in coordination with the four second hydraulic cylinders 4 to jointly provide a stable supporting force through the eight chucks 5 to ensure the smooth movement of the electrode column 1 during the process of lowering the electrode. Remote control allows the operator to operate away from the equipment, improving the safety and convenience of the operation.

[0022] After the electrode column 1 reaches the predetermined position, first, the output shafts of the first hydraulic cylinders 3 are retracted through remote control to reduce the supporting force of the chucks 5 on the electrode column 1. Subsequently, the operator manually operates the second hydraulic cylinders 4 to retract their output shafts, and the chucks 5 are separated from the electrode column 1 to complete the release action. The present utility model only protects the mechanical part, and the functions realized through the software control part related thereto are not within the protection scope of the present utility model.
