[0020] The utility model discloses an electrode fixing device of electric furnace, including guide portion 1, first fixed part 3, moving part 4, elastic part 5 and drive component 6.

[0021] The first direction can be the direction shown by the X axis in the drawing, and the first direction can also be parallel to the length direction of the guide portion 1.

[0022] The clamping space formed by the moving part 4 and the first fixed part 3 is used for clamping the electrode.

[0023] The moving part 4 is arranged between the first fixed part 3 and the second fixed part 2, when the moving part 4 moves away from the first fixed part 3, the electrode is relaxed.

[0024] When the moving part 4 moves away from the first fixed part 3, the elastic part 5 is compressed.

[0025] The elastic part 5 is arranged between the second fixed part 2 and the moving part 4, on the one hand, the elastic recovery force generated when the elastic part 5 is compressed acts on the moving part 4, can make the moving part 4 and the first fixed part 3 more stably clamp the electrode, improve the fixed reliability of the electrode.

[0026] The second fixed part 2 can be used to provide support force when the elastic part 5 is compressed on the one hand, and can be used to install and fix the drive component 6 on the other hand.

[0027] The driving component 6 can be configured to be remotely controlled, and when the moving end of the driving component 6 moves, the moving component 4 can be driven to move, so that the clamping or loosening of the electrode can be remotely operated, improving the safety during the elongation operation of the electrode.

[0028] In some embodiments, the driving component 6 includes a hydraulic cylinder configured to be controlled by the control component.

[0029] The hydraulic cylinder is used to provide power for moving the moving component 4.

[0030] The structure and working principle of the hydraulic cylinder are known to those skilled in the art, and will not be described here.

[0031] The control component controls the flow of hydraulic oil in the hydraulic cylinder to control the operation of the hydraulic cylinder, so that the control of the hydraulic cylinder can be remotely completed, and the clamping or loosening of the electrode can be remotely operated, improving the safety during the elongation operation of the electrode.

[0032] In some embodiments, the control component includes a solenoid valve.

[0033] The flow of hydraulic oil is controlled by the solenoid valve, so that the working state of the hydraulic cylinder can be remotely adjusted.

[0034] The specific oil circuit of the hydraulic cylinder, the supporting hydraulic station required for the operation of the hydraulic cylinder, the setting mode of the solenoid valve in the oil circuit, and the specific principle of the solenoid valve controlling the flow of hydraulic oil are known to those skilled in the art, and the present application does not improve this part, so it will not be described here.

[0036] In some embodiments, the hydraulic cylinder includes a telescopic end, the telescopic end forms the moving end, and the hydraulic cylinder is configured such that when the telescopic end moves into the cylinder body of the hydraulic cylinder, the telescopic end drives the moving component 4 away from the first fixed component 3.

[0037] When the hydraulic oil in the hydraulic cylinder flows, the telescopic end can move relative to the cylinder body of the hydraulic cylinder, so that the telescopic end can drive the moving component 4 to move.

[0038] When the telescopic end moves into the cylinder body of the hydraulic cylinder, the telescopic end drives the moving component 4 away from the first fixed component 3, which has the advantage that compared to the telescopic end moving out of the cylinder body to drive the moving component 4 away from the first fixed component 3, the space occupied by the device can be saved, so that the device as a whole can be more compact.

[0039] In the embodiment in which the control component comprises a solenoid valve, the solenoid valve is powered, at which time the telescopic end moves into the hydraulic cylinder, the moving part 4 and the first fixed part 3 are separated, and the electrode is released.

[0044] In some embodiments, along the first direction, threaded parts 7 are threadedly connected on both sides of the guide part 1, and the first fixed part 3 and the second fixed part 2 are arranged between the two threaded parts 7.

[0045] The threaded part 7 is used to limit the distance between the first fixed part 3 and the second fixed part 2.

[0046] The threaded part 7 is threadedly connected to the guide part 1, so that the position of the threaded part 7 relative to the guide part 1 can be adjusted by rotating the threaded part 7, and the distance between the two threaded parts 7 in the first direction can also be adjusted.

[0047] In the embodiment of the present application, the two threaded parts 7 can be detachably connected with the first fixed part 3 and the second fixed part 2 respectively. When the position of the threaded part 7 is adjusted, the first fixed part 3 and the second fixed part 2 can be connected with the corresponding threaded part 7 respectively, so that the distance between the first fixed part 3 and the second fixed part 2 can be fixed.
