[0025] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.

[0026] Please refer to Figure 1 , Figure 1 which is a perspective view of the optimal embodiment of the electrode vertical extension device for an electric arc furnace of the present utility model. As Figure 1 shown, at least one embodiment provides an electrode vertical extension device for an electric arc furnace, including: a docking support plate 1, the bottom surface of the docking support plate 1 is connected with a driving structure, the driving structure includes a cylinder, the output end of the cylinder is rotatably connected to the bottom surface of the docking support plate, and under the drive of the cylinder, the docking support plate 1 can rotate by 0° - 90°. Additionally, it should be noted that the docking support plate 1 is rotatably connected to the use surface, and the use surface includes the top surface of the lifting workbench. Specifically, after the graphite electrode 10 is sent onto the docking support plate 1, the extension device is lifted to a certain height by the elevator, and then the docking support plate 1 is driven by the cylinder to rotate 90°, so that the graphite electrode 10 is in a vertical state, and then the upright docking effect is achieved through the cooperation of the lifting device, solving the problem that the end face of the graphite electrode 10 is easily damaged during manual docking, improving the docking efficiency, and reducing the labor intensity.

[0027] The docking support plate 1

[0028] Please continue to refer to Figure 1 and in combination with Figures 2 to 3 , Figure 2 which is the front view structure diagram of the electrode vertical extension device for an electric arc furnace of the present utility model; Figure 3 which is the upright state structure diagram of the electrode vertical extension device for an electric arc furnace of the present utility model. As Figures 1 to 3 shown, the docking support plate 1 has a feeding position 4 and a material placement position 5 corresponding to the feeding position 4. A baffle 6 is installed at the edge of the material placement position 5. The docking support plate 1 also has an upright top surface 2 and an upright bottom surface 3 corresponding to the upright top surface 2. The distance between the upright bottom surface 3 and the upright top surface 2 is greater than the length of the graphite electrode 10. A material supporting plate 7 is installed at the position of the upright bottom surface 3. One side of the material supporting plate 7 is flush with the feeding position 4, and the other side is flush with the material placement position 5.

[0029] The material guiding table 8

[0030] A material guiding table 8 is installed on the top surface of the feeding position 4, and the graphite electrode 10 rolls from the position of the material guiding table 8 until it abuts against the baffle 6. The material guiding table 8 includes a flat plate 81 and an inclined plate 82. The flat plate 81 and the inclined plate 82 are integrally formed structures, and the top surface of the flat plate 81 is flush with one side edge of the inclined plate 82. In order to make the rolling speed of the graphite electrode 10 neither too fast nor too slow, the thickness of the flat plate 81 is set to be 1 / 4 - 1 / 2 of the diameter of the graphite electrode 10. The inclined angle of the inclined surface of the inclined plate 82 is set to be 30° - 45°.

[0031] Buffer structure 9

[0032] Please refer to Figure 4 , Figure 4 , which is a perspective view of the optimal embodiment of the buffer structure of the present utility model. As Figure 4 shown, in order to make the graphite electrode 10 stop stably when it rolls to the upright docking position, a plurality of buffer structures 9 are provided on one side of the baffle 6 facing the feeding position 4. In addition, the buffer structure 9 can also play a role in relatively fixing the graphite electrode 10 during the upright process, reducing the risk of the graphite electrode 10 tilting and falling. The buffer structures 9 are arranged at equal intervals. The buffer structure 9 includes a rubber plate 91, and the hardness of the rubber plate 91 is 50 - 62 Shore degrees; one side of the rubber plate 91 is a concave surface 92, and the radius of the concave surface 92 matches the radius of the graphite electrode 10. A plurality of air bag balls 93 are arranged on the concave surface 92, and suction cups 94 are arranged at positions near both ends of the concave surface 92. An air exchange hole 95 is opened at the center position of the suction cup 94, and the air exchange hole 95 is communicated with the air bag balls 93 through a trachea. When the graphite electrode 10 collides with the air bag balls 93, it will compress them and abut against the concave surface 92 and the suction cups 94 to play a buffering effect. After buffering, the air bag balls 93 need to rebound, and the trachea inhales air through the air exchange hole 95. At this time, the suction force cooperates with the suction cups 94 to grip the graphite electrode 10, so that the surface of the graphite electrode 10 has an equally spaced adsorption force, thereby effectively avoiding the problem of tilting and falling during the process of the graphite electrode 10 changing from a horizontal state to an upright state.

[0033] In summary, by setting the rotatable docking support plate 1, the problem that the end face of the graphite electrode 10 is easily damaged due to manual docking is solved, the docking efficiency is improved, and the labor intensity is reduced; by setting the material guiding table 8, the graphite electrode 10 can automatically roll into the installation position after feeding, reducing the operation steps of the staff and shortening the time required for docking; by setting the buffer structure 9, not only the surface of the graphite electrode is prevented from being damaged, but also the graphite electrode 10 during the upright process can be relatively fixed, reducing the risk of the graphite electrode 10 tilting and falling.

[0034] Inspired by the above-described ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
