Description

Technical Field

[0001] This invention relates to the field of steelmaking technology, and in particular to an electrode replacement auxiliary device. Background Technology

[0002] In the smelting of various alloys and metals, graphite electrodes are required for heat treatment. An electrode is a two-end device used to input or output current in a conductive medium (solid, gas, vacuum or electrolyte solution). Because the electrode length is insufficient after being consumed by electricity, a new electrode needs to be connected to the tail of the working electrode in a timely manner. When it is necessary to replace the graphite electrode, it is usually necessary to use an overhead crane to lift and replace the graphite electrode.

[0003] The existing publication number CN212146213U describes an auxiliary device for replacing graphite electrodes. This solution uses clamping components to clamp the graphite electrodes more smoothly and reliably. The clamping components are bolts, and threaded holes are provided on the side wall of the mounting device. The clamping components are threadedly connected to the threaded holes on the side wall of the mounting device. Multiple sets of clamping mechanisms are used to fix the installed graphite electrodes, thereby making the clamping method of graphite electrodes simpler, easier to operate, and lower in manufacturing cost.

[0004] Although the above solution improves the installation method of graphite electrodes, the electrodes often wobble during hoisting and replacement, making it difficult to insert them into the holes when replacing them. Intervention is often required to ensure that the electrodes are accurately aligned with the holes. However, assisting in inserting the electrodes into the holes prolongs the operation time of electrode replacement, and there are also safety hazards when intervening in the electrode alignment. Therefore, an electrode replacement auxiliary device is proposed to address the above problems. Summary of the Invention

[0009] In one embodiment of the present invention, a side plate is fixedly connected to one side of the top plate. The side plate is L-shaped. A rotary motor is fixedly connected to the top of one side of the side plate. A rotating rod is fixedly connected to the output end of the rotary motor. A support plate is fixedly connected to the top of the rotating rod. The support plate is located at the top of the top plate. A connecting plate is fixedly connected to one side of the rotating rod. A collar is fixedly connected to the side of the connecting plate away from the rotating rod. The collar has a bevel at its top. The collar is located at the top of the mounting cylinder. The collar is located at the bottom of the guide plate. The collar is cylindrical in shape.

[0010] In one embodiment of the present invention, a horizontal plate is fixedly connected to one side of the top plate, the horizontal plate is disposed at the bottom of the support plate, a vertical rod is fixedly connected to the top of the horizontal plate, the vertical rod is disposed on one side of the column, a limiting rod is fixedly connected to one side of the column, and the limiting rod is disposed on one side of the vertical rod.

[0011] In one embodiment of the present invention, an inclined block is fixed to the top of the top plate, the inclined block is disposed at the top of one side of the slide groove, and there are two sets of inclined blocks, which are symmetrically distributed at the top of the two sets of slide grooves.

[0012] In one embodiment of the present invention, an arc-shaped plate is fixed to one side of the guide plate, the shape of one side of the arc-shaped plate is fitted to one side of the guide plate, and six sets of arc-shaped plates are arranged in a circular pattern on the outer wall of the guide plate.

[0013] In one embodiment of the present invention, a protrusion is fixed to the side of the arc-shaped plate away from the guide plate, and the protrusion is disposed at the top of the top plate.

[0014] In one embodiment of the present invention, a slot is provided at the top of the top plate. The slot is square in shape. A rod is fixed to one side of the bottom of the guide plate. The rod is rectangular in shape and is inserted into the inner wall of the slot. Two sets of rods are provided and are symmetrically distributed on both sides of the guide plate.

[0015] In one embodiment of the present invention, the top of the guide plate is fixedly connected to a top opening, and the top opening has a curled cross-section.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] 1. This invention, by setting a guide plate at the top of the top plate, facilitates the insertion of the electrode body into the guide plate. The shape of the guide plate guides the electrode body to gradually shift towards the center, allowing the electrode body to gradually stop wobbling after continuously contacting the guide plate. This facilitates the bottom of the electrode body extending into the bottom of the guide plate, allowing the electrode to be straightened by the inner wall of the guide plate and moved vertically downward until the bottom of the electrode body is fully inserted into the inner wall of the mounting cylinder, thus completing the installation of the electrode body and solving the problem of inaccurate electrode alignment during electrode replacement.

[0019] 2. This invention uses a push plate to move the electrode body downwards, which in turn pushes the push plate. The slope at the bottom of the inner wall of the push plate helps the electrode body push the push plate downwards. When the push plate is pushed downwards, it will cause the connecting block on one side to move downwards as well. When the connecting block moves, it will cause the rotating cylinder to rotate around the circular rod. When the rotating cylinder rotates, it will cause the connecting arm and the guide plate to rotate together. The guide plate is arc-shaped and will gradually fit against one side of the electrode body when it rotates. After the bottom of the electrode body moves to the bottom of the push plate, the inner wall of the guide plate will completely fit against the outer wall of the top of the electrode body. After both sets of guide plates move towards the center at the same time, they will force the top of the electrode body to remain vertical, which makes it convenient for the electrode body to be installed vertically downwards into the mounting cylinder.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Please see Figures 1-8 As shown, an electrode replacement auxiliary device includes a top plate 1; a support column 2 is fixedly connected to the bottom of the top plate 1, a base plate 40 is fixedly connected to the bottom of the support column 2, an mounting cylinder 3 is provided at the top of the base plate 40, and a guide assembly is provided at the top of the top plate 1.

[0032] The guiding assembly includes a guide plate 16, which is fixedly connected to the center of the top end of the top plate 1. The guide plate 16 is funnel-shaped and is used to limit the electrode body 15. The guide plate 16 penetrates the top plate 1. A rib 17 is fixedly connected to one side of the guide plate 16, and a connecting rod 18 is fixedly connected to one side of the guide plate 16. There are three sets of ribs 17 and connecting rods 18, which are circumferentially distributed on the outer wall of the guide plate 16.

[0033] To address the issue of inaccurate electrode alignment during electrode replacement, when installing a new electrode, the electrode body 15 is moved to the top of the guide plate 16 via hoisting. The electrode body 15 is then gradually moved downwards until its bottom extends into the inner wall of the guide plate 16. The funnel shape of the guide plate 16 guides the electrode body 15 towards the center, aligning it with the axis of the mounting cylinder 3 at the bottom. Upon contact with the guide plate 16, the electrode body 15 gradually stops wobbling until its bottom extends into the bottom of the guide plate 16. The inner wall of the guide plate 16 then straightens the electrode body 15, which is then moved vertically downwards until its bottom is fully inserted into the inner wall of the mounting cylinder 3. This completes the precise installation of the electrode body 15 and the mounting cylinder 3. The ribs 17 and connecting rods 18 on the outer wall of the guide plate 16 enhance its stability.

[0034] Furthermore, such as Figure 2 and Figure 3 As shown, the top plate 1 has a groove 19 at its top. A round rod is fixed to the inner wall of the groove 19. A rotating cylinder 20 is hinged to the outer wall of the round rod. A connecting block 21 is fixed to the bottom of the rotating cylinder 20. A push plate 22 is fixed to the bottom of the connecting block 21. The push plate 22 is located at the bottom of the guide plate 16. A connecting arm 23 is fixed to the top of the rotating cylinder 20. The connecting arm 23 is C-shaped. A guide plate 24 is fixed to one side of the top of the connecting arm 23. The guide plate 24 is arc-shaped. The guide plate 24 is located at the top of the guide plate 16. The round rod, rotating cylinder 20, connecting block 21, push plate 22, connecting arm 23 and guide plate 24 are all provided in two sets and are symmetrically distributed on both sides of the guide plate 16.

[0035] In the initial state, because the connecting arm 23 has a C-shaped structure and is heavier than the connecting block 21, the connecting arm 23 expands outward in the initial state. Even if one side of the connecting arm 23 is attached to the inclined side of the slide groove 19, the connecting arm 23 and the guide plate 24 are fully open when there is no need to connect or replace the electrode, and the push plate 22 is closable. After the push plate 22 is opened, its height does not exceed the top opening 34; the push plates 22 are close to each other, and the guide plates 24 are far apart; after the electrode body 15 moves downward to the inner wall of the guide plate 16, it will first contact the push plate 22 at the bottom of the guide plate 16, and during the downward movement of the electrode body 15, it will squeeze the slope on the push plate 22. After applying pressure to both sides, the connecting block 21 on one side will deflect downwards together, and under the connection of the rotating cylinder 20, the connecting arm 23 and the guide plate 24 will deflect upwards together, so that the guide plate 24 is aligned vertically with the push plate 22. Since the guide plate 24 is arc-shaped, when it rotates to be aligned vertically with the push plate 22 and remains vertical, it will fit against one side of the electrode body 15. After the bottom of the electrode body 15 completely penetrates the bottom of the push plate 22, the inner wall of the guide plate 16 will completely fit against the outer wall of the top of the electrode body 15. After the two sets of guide plates 16 move towards the center at the same time, they will force the electrode body 15 to be vertically restricted, so that the electrode body 15 can be vertically installed into the mounting cylinder 3.

[0036] Furthermore, such as Figure 4 As shown, a side plate 4 is fixedly connected to one side of the top plate 1. The side plate 4 is L-shaped. A rotary motor 5 is fixedly connected to the top of one side of the side plate 4. A rotating rod 6 is fixedly connected to the output end of the rotary motor 5. A support plate 7 is fixedly connected to the top of the rotating rod 6. The support plate 7 is located at the top of the top plate 1. A connecting plate 29 is fixedly connected to one side of the rotating rod 6. A collar 30 is fixedly connected to the side of the connecting plate 29 away from the rotating rod 6. The collar 30 has a bevel at its top and is located at the top of the mounting cylinder 3. The collar 30 is located at the bottom of the guide plate 16 and is cylindrical in shape.

[0037] By setting a connecting plate 29 on one side of the rotating rod 6, the collar 30 can be installed at the bottom of the top plate 1 through the connecting plate 29. When the rotating motor 5 is started, the rotating rod 6 will rotate to one side, thereby driving the connecting plate 29 and the collar 30 to rotate together. After the electrode body 15 is lifted, the rotating rod 6 will rotate in the opposite direction and reset, driving the connecting plate 29 and the collar 30 to reset together. By setting the collar 30, the bottom of the electrode body 15 can be guided after passing the push plate 22, so that the electrode body 15 falls vertically. After the electrode body 15 is completely vertical, it will be perpendicular to the inner wall of the mounting cylinder 3. The inner wall of the mounting cylinder 3 is aligned with the inner wall of the guide plate 16, which makes it convenient to insert the electrode body 1 into the inner wall of the mounting cylinder 3.

[0038] Furthermore, such as Figure 4 and Figure 8 As shown, a horizontal plate 35 is fixed to one side of the top plate 1. The horizontal plate 35 is located at the bottom of the support plate 7. A vertical rod 36 is fixed to the top of the horizontal plate 35. The vertical rod 36 is located on one side of the column 9. A limiting rod 37 is fixed to one side of the column 9. The limiting rod 37 is located on one side of the vertical rod 36.

[0039] When the column 9 needs to be reset, it will move the limit rod 37 on one side together until the limit rod 37 rotates to the side of the column 36 and is blocked by the column 36. At this time, the rotation of the rotary motor 5 stops, which can facilitate the reset of the column 9 and make the position of the column 9 after reset accurate.

[0040] Furthermore, such as Figure 1 and Figure 7 As shown, an inclined block 8 is fixed to the top of the top plate 1. The inclined block 8 is set at the top of one side of the slide groove 19. There are two sets of inclined blocks 8, which are symmetrically distributed at the top of the two sets of slide grooves 19.

[0041] By setting two sets of inclined blocks 8 at the top of the top plate 1, when the connecting arm 23 is tilted to both sides of the slide groove 19, the two sets of inclined blocks 8 can provide support for both sides of the connecting arm 23, preventing the connecting arm 23 from tilting excessively to both sides.

[0042] Furthermore, such as Figure 5 and Figure 6 As shown, an arc-shaped plate 32 is fixed to one side of the guide plate 16. The arc-shaped plate 32 is shaped to fit one side of the guide plate 16. There are six sets of arc-shaped plates 32, which are distributed in a circle on the outer wall of the guide plate 16.

[0043] By providing an arc-shaped plate 32 on one side of the guide plate 16, the guide plate 16 can be supported by the arc-shaped plate 32 when it is installed on the top plate 1, which helps to improve the stability of the outer wall of the guide plate 16.

[0044] Furthermore, such as Figure 5 and Figure 6 As shown, a protrusion 10 is fixed to the side of the arc plate 32 away from the guide plate 16, and the protrusion 10 is disposed at the top of the top plate 1.

[0045] By providing a protrusion 10 on one side of the arc plate 32, the bottom of the protrusion 10 can contact the top plate 1, thereby increasing the force-bearing contact surface and providing stable support for the bottom of the arc plate 32.

[0046] Furthermore, such as Figure 6 and Figure 7As shown, a slot 31 is provided at the top of the top plate 1. The slot 31 is square in shape. A rod 33 is fixed to one side of the bottom of the guide plate 16. The rod 33 is rectangular in shape. The rod 33 is inserted into the inner wall of the slot 31. There are two sets of rods 33, which are symmetrically distributed on both sides of the guide plate 16.

[0047] By providing a slot at the top of the top plate 1, when the guide plate 16 is installed at the top of the top plate 1, the insertion rod 33 at the bottom of the guide plate 16 can be inserted into the inner wall of the slot. Under the influence of gravity, the insertion rod 33 fits against the inner wall of the slot, thereby preventing the guide plate 16 from shifting when the electrode body 15 touches the guide plate 16, and at the same time facilitating the disassembly of the guide plate 16.

[0048] Furthermore, such as Figure 5 As shown, the top of the guide plate 16 is fixedly connected to a top opening 34, and the cross-section of the top opening 34 is curled.

[0049] By providing a curled top opening 34 at the top of the guide plate 16, the electrode body 15 can be easily slid towards the center of the guide plate 16 through the curled top opening 34 when it moves downward to the top of the guide plate 16.

[0050] Furthermore, such as Figure 1 and Figure 7 As shown, a wedge 11 is fixed to the top of one side of the support column 2. The wedge 11 is triangular in shape, and the top of the wedge 11 is fixed to the bottom of the top plate 1.

[0051] By setting an inclined plate 11 on one side of the support column 2, the triangular feature of the inclined plate 11 can provide stable support for the connection between the support column 2 and the top plate 1, thereby improving stability.

[0052] Working Principle: To solve the problem of inaccurate electrode alignment during electrode replacement, when a new electrode needs to be installed, the electrode body 15 is moved to the top of the guide plate 16 by hoisting, and then gradually moved downwards until the bottom of the electrode body 15 extends into the inner wall of the guide plate 16. The electrode body 15 slides towards the center of the guide plate 16 through the curled top opening 34. The funnel shape of the guide plate 16 guides the electrode body 15 towards the center, and when the electrode body 15 contacts the guide plate 16, it gradually... The shaking gradually stops until the bottom of the electrode body 15 extends into the bottom of the guide plate 16. As it moves downwards, the electrode body 15 contacts the push plate 22 at the bottom of the guide plate 16. When the push plate 22 is pushed downwards, it causes the connecting block 21 on one side to move downwards as well. The movement of the connecting block 21 causes the rotating drum 20 to rotate around the circular rod. As the rotating drum 20 rotates, it causes the connecting arm 23 and the guide plate 24 to rotate together. The guide plate 16 is arc-shaped, and as it rotates, it gradually conforms to one side of the electrode body 15, while the bottom of the electrode body 15 moves downwards... After the guide plate 22 is moved to the bottom, the inner wall of the guide plate 16 will completely fit against the outer wall of the top of the electrode body 15. When both sets of guide plates 16 move towards the center at the same time, the top of the electrode body 15 will be forced to remain vertical. The mounting cylinder 3 is placed at the bottom of the top plate 1, and the mounting hole of the mounting cylinder 3 is aligned with the bottom of the guide plate 16. The rotary motor 5 is started to rotate the rotating rod 6 to one side, thereby driving the connecting plate 29 and the collar 30 to rotate together. After the electrode body 15 is lifted, the rotating rod 6 will rotate in the opposite direction and return to its original position, while driving the connecting plate 29 to rotate. The electrode body 15 is reset together with the collar 30. By setting the collar 30, the bottom of the electrode body 15 can be guided after passing through the push plate 22, so that the electrode body 15 falls vertically. After the electrode body 15 is completely vertical, it will be perpendicular to the inner wall of the mounting cylinder 3. The inner wall of the mounting cylinder 3 is aligned with the inner wall of the guide plate 16, which makes it easy to insert the electrode body 15 into the inner wall of the mounting cylinder 3, thus completing the installation of the electrode body 15. The ribs 17 and connecting rods 18 set on the outer wall of the guide plate 16 can be used to improve the stability of the outer wall of the guide plate 16.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
