Description

Technical Field

[0001] This utility model relates to the technical field of electrode replacement devices, and in particular to an electrode replacement device for an electroslag remelting furnace. Background Technology

[0002] In today's industrial manufacturing sector, electroslag remelting furnaces are key equipment for refining high-quality metallic materials. Their working principle relies on the resistance heat generated by current passing through molten slag to melt and refine metal electrodes, producing high-quality metal ingots. However, due to the high temperature, high current density, and complex chemical environment in which the electrodes operate, they wear out rapidly, making frequent electrode replacement a necessary operation to maintain production continuity. Developing an efficient and reliable electrode replacement device for electroslag remelting furnaces is of great significance for improving production efficiency and reducing production costs.

[0003] Current technologies for electrode replacement in electroslag remelting furnaces mostly employ relatively traditional mechanical connection and disassembly methods. Operators use hand tools such as wrenches and screwdrivers to disassemble and install bolts, nuts, and other fasteners at the connection points between the electrode and the furnace one by one. The entire technical principle relies on the precise lifting of cranes and manual operation to complete the electrode replacement process.

[0004] However, this traditional electrode replacement method, or electrode replacement process, is extremely complex and time-consuming. From the moment the electrode is hoisted by the lifting equipment to the operator gradually disassembling and reinstalling the fasteners at multiple connection points, each step must be performed strictly in sequence, and the operation requires a high level of skill and physical strength from the operator. The entire replacement process often consumes a significant amount of time, leading to prolonged downtime of the electroslag remelting furnace. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electrode replacement device for an electroslag remelting furnace, which aims to improve the problem that the traditional electrode replacement method and process are extremely complicated and time-consuming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrode replacement device for an electroslag remelting furnace, comprising a mounting base, a fixing disk fixedly connected to the lower surface of the mounting base, an electrode body disposed below the mounting base, and an installation assembly disposed inside the electrode body;

[0007] The installation assembly includes a first locking block, which is disposed inside the electrode body. A sliding rod is fixedly connected to the upper surface of the first locking block, and a second fixing disk is slidably connected to the outer wall of the sliding rod. A first sliding groove is opened inside the second fixing disk, and a connecting rod is fixedly connected to the outer wall of the second fixing disk. A rotating ring is fixedly connected to the outer wall of the connecting rod, and a fixing plate is disposed below the second fixing disk.

[0008] Furthermore, a fixing post is fixedly connected to the upper surface of the fixing plate, a knob is rotatably connected to the upper surface of the fixing post, a threaded rod is fixedly connected to the outer wall of the knob, a spring is sleeved on the outer wall of the threaded rod, a sliding groove is opened inside the knob, and a locking block is threadedly connected to the outer wall of the threaded rod.

[0009] Furthermore, the outer wall of the first locking block is slidably connected to the inner wall of the fixing plate, and the first locking block is used to fix the electrode body.

[0010] Furthermore, the knob is positioned above the fixed disk and is used to drive the threaded rod to rotate.

[0011] Furthermore, one end of the spring is fixedly connected to the inner wall of the fixed column, and the other end of the spring is fixedly connected to the outer wall of the second locking block.

[0012] Furthermore, the outer wall of the second locking block is slidably connected to the inner wall of the fixed column, and the second locking block is used to fix the rotating ring.

[0013] Furthermore, the fixing plate is disposed inside the electrode body, and the fixing plate is used to guide the sliding of the first card block.

[0014] Furthermore, the outer wall of the second locking block is slidably connected to the inner wall of the rotating ring, and the second locking block is used to fix the rotating ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by rotating the rotating ring, the fixed disk can be easily rotated, which in turn causes the slide rod to move along the slide groove, causing the locking block to slide and lock into the electrode body to achieve fixation. Rotating the rotating ring in the opposite direction can quickly release the fixation, which greatly simplifies the electrode replacement process, significantly improves work efficiency, and reduces equipment downtime caused by electrode replacement.

[0017] 2. In this utility model, after the first locking block is inserted into the electrode body, rotating the knob can drive the threaded rod to rotate, causing the second locking block to be inserted into the rotating ring, thereby further reinforcing the electrode body and effectively preventing the electrode body from falling off due to accidents during operation. This ensures the safety of equipment operation, improves the reliability of the electroslag remelting furnace, and reduces safety risks. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an electrode replacement device for an electroslag remelting furnace, including a mounting base 1, a fixing disk 4 fixedly connected to the lower surface of the mounting base 1, an electrode body 2 disposed below the mounting base 1, and an installation component disposed inside the electrode body 2.

[0026] The mounting assembly includes a locking block 10, which slides along the inside of the fixing plate 9 under the action of the slide rod 6, locking into a pre-set slot inside the electrode body 2 to achieve initial fixation of the electrode body 2. When moving in the reverse direction, it disengages from the slot, facilitating the replacement of the electrode body 2. The locking block 10 is located inside the electrode body 2, and the slide rod 6 is fixedly connected to its upper surface. When the fixing plate 2 5 rotates, the slide rod 6 moves along the direction of the sliding groove 8, converting the rotation of the fixing plate 2 5 into linear motion, thereby driving the locking block 10 to slide along the internal slide of the fixing plate 9. The fixing plate 2 5 is slidably connected to the outer wall of the slide rod 6. When the rotating ring 3 rotates, the fixing plate 2 5 rotates synchronously, with its internal sliding groove... The first 8 provides a specific trajectory for the movement of the slide bar 6, guiding the slide bar 6 to move along the designed route, thereby driving the first 10 of the locking block to complete the fixing and disengaging action of the electrode body 2. The second fixing plate 5 has a sliding groove 8 inside, and a connecting rod 7 is fixedly connected to the outer wall of the second fixing plate 5. A rotating ring 3 is fixedly connected to the outer wall of the connecting rod 7. By manually rotating the rotating ring 3, the second fixing plate 5 connected to it can be rotated. A fixing plate 9 is set below the second fixing plate 5 and installed inside the electrode body 2 to provide precise guidance for the sliding of the first 10 of the locking block, ensuring that the first 10 of the locking block can accurately lock into or disengage from the locking groove of the electrode body 2 during the movement, and ensuring the accuracy of the fixing and disengaging operation.

[0027] Specifically, the operator manually rotates the rotating ring 3, which is securely connected to the fixed disk 5 via the connecting rod 7. Therefore, the rotation of the rotating ring 3 directly drives the fixed disk 5 to rotate synchronously. The fixed disk 5 has a sliding groove 8 inside. One end of the sliding rod 6 is fixedly connected to the locking block 10, and the other end can slide smoothly in the sliding groove 8. As the fixed disk 5 rotates, the sliding groove 8 guides the sliding rod 6 to move along a specific trajectory. The movement of the sliding rod 6 then drives the locking block 10 connected to it to move. The locking block 10 slides in the slide rail inside the fixed plate 9. The fixed plate 9 is installed inside the electrode body 2 and plays a precise guiding role. Finally, the locking block 10 is successfully locked into the preset locking slot of the electrode body 2, completing the initial fixation of the electrode body 2. When it is necessary to release the fixation of the electrode body 2, the operator only needs to rotate the rotating ring 3 in the opposite direction. At this time, the sliding rod 6 will move in the opposite direction along the sliding groove 8, driving the locking block 10 to disengage from the locking slot inside the electrode body 2, so that the electrode body 2 can be quickly replaced, greatly improving work efficiency.

[0028] Reference Figure 4A fixed post 11 is fixedly connected to the upper surface of the fixed disk 4. A knob 15 is rotatably connected to the upper surface of the fixed post 11. By manually rotating the knob 15, the threaded rod 12 fixedly connected to it is driven to rotate, thereby controlling the movement of the locking block 13 and realizing the locking and unlocking of the rotating ring 3. This further reinforces or releases the electrode body 2. The threaded rod 12 is fixedly connected to the outer wall of the knob 15, pushing the locking block 13 into or out of the rotating ring 3 to realize the locking and unlocking of the rotating ring 3. A spring 14 is sleeved on the outer wall of the threaded rod 12, which plays a role in buffering and assisting in reset. During the movement of the locking block 13, it provides a certain elastic force to make the movement of the locking block 13 more stable, and assists the locking block 13 to reset smoothly when unlocking. A sliding groove 16 is opened inside the knob 15, and the locking block 13 is threadedly connected to the outer wall of the threaded rod 12. 13. Driven by the threaded rod 12, it slides on the inner wall of the fixed column 11 and the inner wall of the rotating ring 3. When it is locked into the inner groove of the rotating ring 3, the rotating ring 3 is locked, thereby strengthening the electrode body 2. The outer wall of the locking block 10 is slidably connected to the inner wall of the fixed plate 9. The locking block 10 is used to fix the electrode body 2. The knob 15 is set above the fixed plate 4. The knob 15 is used to drive the threaded rod 12 to rotate. One end of the spring 14 is fixedly connected to the inner wall of the fixed column 11, and the other end of the spring 14 is fixedly connected to the outer wall of the locking block 2 13. The outer wall of the locking block 2 13 is slidably connected to the inner wall of the fixed column 11. The locking block 2 13 is used to fix the rotating ring 3. The fixed plate 9 is set inside the electrode body 2. The fixed plate 9 is used to provide guidance for the sliding of the locking block 10. The outer wall of the locking block 2 13 is slidably connected to the inner wall of the rotating ring 3. The locking block 2 13 is used to fix the rotating ring 3.

[0029] Specifically, after the locking block 10 is successfully inserted into the electrode body 2 and initially fixed, a locking operation is required to further ensure the stability of the electrode during operation. The operator rotates the knob 15 located above the fixing plate 4. The knob 15 is fixedly connected to the threaded rod 12. When the knob 15 is rotated, the threaded rod 12 rotates accordingly. A spring 14 is sleeved on the outer wall of the threaded rod 12. One end of the spring 14 is fixed to the inner wall of the fixing post 11, and the other end is connected to the locking block 13. The locking block 13 can slide on the inner wall of the fixing post 11 and the inner wall of the rotating ring 3. As the threaded rod 12 rotates, its threaded structure pushes the locking block 13. The electrode body 2 moves along the inner wall of the fixed column 11 toward the rotating ring 3 until the second locking block 13 is engaged in the groove inside the rotating ring 3, thereby locking the rotating ring 3 and further reinforcing the electrode body 2. When the electrode body 2 needs to be disassembled, the operator rotates the knob 15 in the opposite direction, the threaded rod 12 rotates in the opposite direction, and drives the second locking block 13 to move in the opposite direction along the inner wall of the fixed column 11, disengaging from the groove inside the rotating ring 3 and releasing the fixation of the rotating ring 3. Through secondary reinforcement, the electrode body 2 can be effectively prevented from accidentally falling off due to vibration, high temperature and other unexpected factors during the operation of the electroslag remelting furnace, ensuring the safe and stable operation of the equipment.

[0030] Working principle: When the electrode replacement device for the electroslag remelting furnace is needed, when the electrode needs to be installed, firstly, by rotating the rotating ring 3, the fixed disk 2 5 is rotated. While the fixed disk 2 5 is rotating, the sliding rod 6 will move along the sliding groove 8. Then, the movement of the sliding rod 6 will cause the locking block 10 to slide along the inside of the fixed plate 9, thereby locking into the electrode body 2 to fix it. When it is necessary to remove the electrode body 2 from the fixation, simply rotate the rotating ring 3 in the opposite direction to make the locking block 10 disengage from the electrode body 2. Quickly replacing the electrode body 2 is beneficial to improving work efficiency.

[0031] In addition, after the first locking block 10 is inserted into the electrode body 2, it needs to be locked. By rotating the knob 15, the threaded rod 12 is rotated, so that the second locking block 13 is inserted into the rotating ring 3, thereby further fixing the electrode body 2. When the electrode body 2 is disassembled, the knob 15 can be rotated in the opposite direction to drive the second locking block 13 out of the rotating ring 3, thereby releasing the rotating ring 3 and further reinforcing the electrode body 2 to prevent the electrode body 2 from falling off accidentally during operation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
