Description

Technical Field

[0001] This invention relates to the field of graphite electrode production equipment technology, specifically a graphite electrode docking device. Background Technology

[0002] Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are produced through calcination, batching, kneading, molding, roasting, graphitization, and machining. Graphite electrodes are widely used in the metal smelting industry. The graphite electrodes used in electric arc furnaces mainly consist of two parts: the electrode body and the electrode connector. The graphite electrode connector is an accessory of the graphite electrode and is used in conjunction with the graphite electrode. The electrode connector is provided with tapered threads. The electrode body and the electrode connector are connected through the tapered threads on the electrode connector. Adjacent electrode bodies are connected through the electrode connector. The connection is convenient and reliable and can withstand high loads.

[0003] Existing graphite electrode docking methods are mostly manual, which is inconvenient, dangerous, time-consuming, and labor-intensive. Graphite electrode docking devices cannot properly fix graphite electrodes, resulting in unstable docking. Therefore, we propose a graphite electrode docking device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a graphite electrode docking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a graphite electrode docking device, comprising a linear electric rail, wherein two linear electric rails are symmetrically distributed, and each linear electric rail is fixedly mounted with a mounting base at its driving end. A lifting mechanism is fixedly mounted on the top of the two mounting bases, and a flipping mechanism is provided on the lifting mechanism. A fixed rotation mechanism is provided in the middle of the flipping mechanism.

[0006] The fixed-rotation mechanism includes two symmetrically distributed fixed frames, and a fixed-rotation component is fixedly installed between the two fixed frames.

[0007] Preferably, the fixed-rotation assembly includes symmetrically distributed fixed-rotation outer frames, each with a semi-circular structure. Two fixed-rotation outer frames are combined to form a circular outer frame. A cavity is formed within the circular outer frame. Multiple evenly distributed positioning slides are slidably mounted on opposite sides of the two fixed-rotation outer frames. The multiple positioning slides are arranged in a circular array. The opposite ends of the multiple positioning slides extend into the cavity. Positioning wheels are movably mounted on opposite ends of the multiple positioning slides. A rotating shaft is fixedly installed in the center of each positioning wheel. The rotating shaft is rotatably mounted on the positioning slide. Each of the outer frames is equipped with symmetrically distributed semi-ring frames. Semi-ring connecting frames are fixedly installed on the outer walls of the two semi-ring frames. The semi-ring connecting frames are rotatably engaged in the corresponding cavities. The semi-ring frames and positioning slides cooperate with each other. The two horizontally corresponding semi-ring frames are combined to form a ring frame. The two semi-ring connecting frames are combined to form a ring connecting frame. The opposite sides of the ring frame are integrally formed with planar threaded protrusions. The upper and lower surfaces of the positioning slides are provided with planar threaded grooves that cooperate with the planar threaded protrusions. The planar threaded protrusions are movably engaged in the corresponding planar threaded grooves.

[0008] Preferably, a semi-toothed ring is fixedly installed in the middle of the outer wall of each semi-ring connecting frame, and two semi-toothed rings are combined to form an annular toothed ring. A drive gear is meshed with the outer side of the semi-toothed ring. The drive gear is located in the middle of the fixed-rotation outer frame.

[0009] Preferably, the top of the positioning slide in the middle of the fixed rotation outer frame is provided with a drive cavity, and the top of the rotating shaft extends into the drive cavity. A crown gear is fixedly sleeved on the top of the rotating shaft. A first motor is fixedly installed in the drive cavity near the crown gear. A transmission gear is fixedly installed on the drive end of the first motor. The transmission gear and the crown gear are meshed and connected.

[0010] Preferably, a fixing column is fixedly installed at each of the opposite ends of the two fixing frames, a connecting seat is fixedly installed at one end of each fixing column, and a telescopic cylinder is fixedly installed between the two connecting seats.

[0011] Preferably, the lifting mechanism includes two symmetrically distributed first longitudinal sliding frames and two symmetrically distributed second longitudinal sliding frames. The first longitudinal sliding frames are fixedly installed on the top of one of the mounting bases, and the second longitudinal sliding frames are fixedly installed on the top of the other mounting base. The two first longitudinal sliding frames are slidably fitted with first slide blocks on opposite sides, and the two second longitudinal sliding frames are slidably fitted with second slide blocks on opposite sides. A lifting screw is rotatably installed in each of the first and second longitudinal sliding frames. The lifting screw is threaded through the ends of the corresponding first and second slide blocks. A connecting frame is fixedly installed at the top of each of the two first and two second longitudinal sliding frames. The top of each lifting screw movably passes through the corresponding connecting frame. Each connecting frame is provided with a pulley drive assembly. The pulley drive assembly includes two pulleys and a drive belt movably sleeved on the outside of the two pulleys. The two pulleys are respectively fixedly sleeved on the outside of the corresponding lifting screw.

[0012] Preferably, a second motor is fixedly installed on one side of the top of the connecting frame, and the drive end of the second motor and the top of the corresponding lifting screw are coaxially fixedly installed.

[0013] Preferably, the flipping mechanism includes a flipping column and a flipping cylinder. The flipping column is rotatably installed in the middle of the first slide block, and the flipping cylinder is rotatably installed in the middle of the second slide block. A telescopic inner shaft is movably engaged on the side of the flipping cylinder near the flipping column. A limiting inner rod is fixedly installed in the middle of the flipping cylinder. A limiting groove is opened in the middle of the telescopic inner shaft to cooperate with the limiting inner rod. The limiting inner rod is movably engaged in the limiting groove. The opposite ends of the flipping column and the telescopic inner shaft are respectively fixedly installed in the middle of the corresponding fixing frame.

[0014] Preferably, a driven worm gear is fixedly sleeved on the opposite ends of the flipping column and the flipping cylinder. A driving worm is meshed with the side end of the driven worm gear. A rotating frame is rotatably mounted on the top and bottom ends of the driving worm. The rotating frame is fixedly mounted to the first slide and the second slide respectively. A third motor is fixedly mounted on the side of the first slide and the second slide near the driving worm. The driving end of the third motor is coaxially fixedly mounted to the top end of the corresponding driving worm.

[0015] Preferably, the method of using the graphite electrode docking device includes the following steps:

[0016] Step 1: Control the activation of the third motors on both sides, which synchronously drive the drive worm gears on both sides to rotate, which in turn synchronously drive the driven worm wheels on both sides to rotate, which in turn synchronously drive the tilting column, tilting cylinder, and telescopic inner shaft to rotate. With the connection of the fixed frame, the fixed rotation assembly is driven to rotate 90 degrees, with the fixed rotation assembly facing vertically downward.

[0017] Step 2: Control the extension of the telescopic cylinder, and in conjunction with the connection of the connecting seat and the fixed column, drive one of the fixed frames away from the other fixed frame, causing the two fixed rotating outer frames to move away from each other, and the telescopic inner shaft to slide in the tilting cylinder.

[0018] Step 3: By controlling the activation of the second motors on both sides, and cooperating with the transmission of the belt pulleys on both sides, multiple lifting screws are driven to rotate synchronously, thereby driving the first slide and the second slide to descend vertically, which in turn drives the fixed-rotation assembly to move down. The middle position of the flat graphite column is moved to pass through the two fixed-rotation outer frames and placed between multiple positioning wheels. Then, the telescopic cylinder is activated to retract, and in conjunction with the connection of the connecting seat and the fixed column, one of the fixed frames is driven to move closer to the other fixed frame, causing the two fixed-rotation outer frames on both sides to move closer to each other. The two fixed-rotation outer frames are combined to form a ring-shaped outer frame, and the two horizontally corresponding semi-ring frames are combined to form a ring-shaped frame. The two semi-ring connecting frames are combined to form a ring connecting frame.

[0019] Step 4: Synchronously control the rotation of the two drive motors, which drive the corresponding drive shafts and drive gears to rotate synchronously in the same direction, thereby driving the annular gear ring to rotate, which in turn drives the annular connecting frame to rotate. The annular frame rotates and engages with the planar threaded protrusion in the corresponding planar threaded groove, synchronously driving multiple positioning slides and positioning wheels to move towards each other, clamping and positioning the graphite column placed between the multiple positioning wheels.

[0020] Step 5: Move the entire fixed-rotation assembly upwards to clamp and position the graphite column. Then, flip the fixed-rotation assembly again to reset it, so that the graphite column is in a vertical position. Turn on the linear electric rails on both sides to drive the mounting base, lifting mechanism, flipping mechanism, fixed-rotation mechanism, and graphite column to translate so that the graphite column and graphite electrode are in the same position.

[0021] Step Six: Synchronous control activates the first motors on both sides to drive the transmission gears to rotate, which in turn drives the rotating shafts and positioning wheels on both sides to rotate synchronously horizontally on the positioning slide, thereby causing the graphite column to rotate automatically horizontally. In conjunction with the entire fixed-rotation assembly and the downward movement of the clamped and positioned graphite column, the graphite column is stably and spirally installed in the graphite electrode, saving time and effort.

[0022] Step 7: After the graphite column and graphite electrode are automatically aligned, the drive motors on both sides are synchronously activated to rotate in opposite directions, driving the corresponding drive shafts and drive gears to rotate synchronously in opposite directions. This, in turn, drives the annular gear ring to rotate in opposite directions, thereby driving the annular connecting frame to rotate in opposite directions. The annular frame rotates in opposite directions and engages with the planar threaded protrusion in the corresponding planar threaded groove. This synchronously drives multiple positioning slides and positioning wheels to move in opposite directions, causing the graphite column to lose its clamping and positioning. The fixed rotation outer frame, semi-annular frame, and semi-annular connecting frame are reset, facilitating the separation of the two fixed rotation outer frames and detachment from the automatically aligned graphite column.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By setting up a fixed rotation mechanism, in conjunction with a lifting mechanism and a flipping mechanism, the flat graphite column is automatically clamped, positioned, flipped, and moved downwards. It can also drive the graphite column to rotate, so that the graphite column is stably installed in the graphite electrode by spiral rotation, saving time and effort, and automatically docking the graphite electrode.

[0025] 2. By setting a fixed-rotation mechanism, multiple positioning carriages and positioning wheels can be driven to move towards each other synchronously, and the spacing of the positioning wheels can be flexibly adjusted to clamp and position graphite columns of different outer diameters for docking, thereby improving the flexibility of the entire graphite electrode docking device.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figure 1-9 As shown, the present invention provides a graphite electrode docking device, including a linear electric rail 1, wherein two linear electric rails 1 are symmetrically distributed, and each linear electric rail 1 is fixedly mounted with a mounting base 2 at its driving end. A lifting mechanism 3 is fixedly mounted on the top of the two mounting bases 2, and a flipping mechanism 4 is provided on the lifting mechanism 3. A fixed rotation mechanism 5 is provided in the middle of the flipping mechanism 4. The two linear electric rails 1 on both sides are opened synchronously, driving the mounting bases 2, lifting mechanism 3, flipping mechanism 4 and fixed rotation mechanism 5 to translate.

[0039] The fixed-rotation mechanism 5 includes two symmetrically distributed fixed frames 51, and a fixed-rotation component 6 is fixedly installed between the two fixed frames 51.

[0040] The fixed-rotation component 6 includes symmetrically distributed fixed-rotation outer frames 61, each with a semi-annular structure. Two fixed-rotation outer frames 61 are combined to form an annular outer frame. A cavity 611 is formed within the annular outer frame. Multiple evenly distributed positioning slides 62 are slidably engaged on opposite sides of the two fixed-rotation outer frames 61. The multiple positioning slides 62 are arranged in a circular array. The opposite ends of the multiple positioning slides 62 extend into the cavity 611, and the opposite ends of the multiple positioning slides 62 are movable. A positioning wheel 63 is provided, and a rotating shaft 631 is fixedly installed in the middle of the positioning wheel 63. The rotating shaft 631 is rotatably mounted on the positioning slide 62. By setting the rotating shaft 631, the positioning wheel 63 can rotate horizontally on the positioning slide 62. The fixed and rotating outer frame 61 is movably fitted with symmetrically distributed semi-ring frames 64. Semi-ring connecting frames 65 are fixedly installed on the outer walls of the two semi-ring frames 64 to fix the two semi-ring frames 64 together. The semi-ring connecting frames 65 are rotatably engaged. In the corresponding cavity 611, the semi-ring frame 64 and the positioning slide 62 cooperate with each other. Two horizontally corresponding semi-ring frames 64 are combined to form a ring frame, and two semi-ring connecting frames 65 are combined to form a ring connecting frame. The opposite sides of the ring frame are integrally formed with planar threaded protrusions. The upper and lower surfaces of the positioning slide 62 are provided with planar threaded grooves that cooperate with the planar threaded protrusions. The planar threaded protrusions are movably engaged in the corresponding planar threaded grooves. By driving the ring connecting frame to rotate, the ring frame is driven to rotate, and the planar threaded protrusions are movably engaged in the corresponding planar threaded grooves. This synchronously drives multiple positioning slides 62 and positioning wheels 63 to move towards each other, clamping and positioning the graphite column placed between the multiple positioning wheels 63. Conversely, by driving the ring connecting frame to rotate in the opposite direction, the ring frame is driven to rotate in the opposite direction, and the planar threaded protrusions are movably engaged in the corresponding planar threaded grooves. This synchronously drives multiple positioning slides 62 and positioning wheels 63 to move away from each other, and the graphite column loses its clamping and positioning.

[0041] Each of the semi-ring connecting frames 65 has a semi-toothed ring 66 fixedly installed in the middle of its outer wall. Two semi-toothed rings 66 are combined to form a ring-shaped toothed ring. Drive gears 67 are meshed with the outer sides of each semi-toothed ring 66. The drive gears 67 on both sides are located in the middle of the corresponding fixed-rotation outer frame 61. A drive shaft 671 is fixedly installed in the middle of each drive gear 67. The drive shaft 671 is rotatably engaged with the corresponding fixed-rotation outer frame 61. A drive motor 672 is fixedly installed on the top of the fixed-rotation outer frame 61 near the drive shaft 671. The drive end of 672 and the top end of the corresponding drive shaft 671 are coaxially fixed. In use, the drive motors 672 on both sides are turned on synchronously, which drives the corresponding drive shaft 671 and drive gear 67 to rotate synchronously in the same direction, thereby driving the annular gear ring to rotate, which in turn drives the annular connecting frame to rotate. Conversely, the drive motors 672 on both sides are turned on synchronously in opposite directions, which drives the corresponding drive shaft 671 and drive gear 67 to rotate synchronously in opposite directions, thereby driving the annular gear ring to rotate in opposite directions, which in turn drives the annular connecting frame to rotate in opposite directions.

[0042] The top of the positioning slide 62, located in the middle of the fixed-rotation outer frame 61, has a drive cavity. The top of the rotating shaft 631 extends into the drive cavity. A crown gear 632 is fixedly sleeved on the top of the rotating shaft 631. A first motor 633 is fixedly installed in the drive cavity near the crown gear 632. A transmission gear 634 is fixedly installed at the drive end of the first motor 633. The transmission gear 634 and the crown gear 632 are meshed and connected. By synchronously controlling the first motors 633 on both sides to drive the transmission gear 634 to rotate, the rotating shafts 631 on both sides and the positioning wheel 63 are driven to rotate synchronously horizontally on the positioning slide 62. This drives the graphite column to rotate automatically horizontally, facilitating the stable spiral rotation of the graphite column in the graphite electrode, saving time and effort.

[0043] Each of the two fixed frames 51 has a fixed post 52 fixedly installed at its opposite ends. A connecting seat 53 is fixedly installed at one end of each fixed post 52. A telescopic cylinder 54 is fixedly installed between the two connecting seats 53. Controlling the telescopic cylinder 54 to extend, in conjunction with the connection of the connecting seat 53 and the fixed post 52, drives one of the fixed frames 51 away from the other fixed frame 51, causing the two fixed rotating outer frames 61 on both sides to move away from each other. Conversely, controlling the telescopic cylinder 54 to retract, in conjunction with the connection of the connecting seat 53 and the fixed post 52, drives one of the fixed frames 51 closer to the other fixed frame 51, causing the two fixed rotating outer frames 61 on both sides to move closer to each other.

[0044] The lifting mechanism 3 includes two symmetrically distributed first longitudinal sliding frames 31 and two symmetrically distributed second longitudinal sliding frames 32. The first longitudinal sliding frames 31 are fixedly installed on the top of one of the mounting bases 2, and the second longitudinal sliding frames 32 are fixedly installed on the top of the other mounting base 2. First sliding blocks 33 are slidably mounted on opposite sides of the two first longitudinal sliding frames 31, and second sliding blocks 34 are slidably mounted on opposite sides of the two second longitudinal sliding frames 32. Lifting screws 35 are rotatably mounted in both the first and second longitudinal sliding frames 31 and 32, respectively. The lifting screws 35 are threaded through the ends of the corresponding first sliding blocks 33 and second sliding blocks 34. Connecting frames 36 are fixedly installed on the tops of both the first and second longitudinal sliding frames 31 and 32, respectively, for connecting and fixing the two first longitudinal sliding frames 31 and 32. The top of the lifting screws 35... The movement extends through the corresponding connecting frame 36, each of which is equipped with a pulley drive assembly 37. Each pulley drive assembly 37 includes two pulleys and a drive belt movably sleeved on the outside of the two pulleys. The two pulleys are respectively fixedly sleeved on the outside of the corresponding lifting screw 35. A second motor 38 is fixedly installed on one side of the top of the connecting frame 36. The drive end of the second motor 38 is coaxially fixedly installed with the top of the corresponding lifting screw 35. By controlling the activation of the two second motors 38, in conjunction with the transmission of the two pulley drive assemblies 37, multiple lifting screws 35 are synchronously driven to rotate, thereby causing the first slide 33 and the second slide 34 to descend vertically. Conversely, by controlling the activation of the two second motors 38, in conjunction with the transmission of the two pulley drive assemblies 37, multiple lifting screws 35 are synchronously driven to rotate in the opposite direction, thereby causing the first slide 33 and the second slide 34 to rise vertically.

[0045] The flipping mechanism 4 includes a flipping column 41 and a flipping cylinder 42. The flipping column 41 is rotatably mounted in the middle of the first slide block 33, and the flipping cylinder 42 is rotatably mounted in the middle of the second slide block 34, providing a rotatable connection between the flipping mechanism 4 and the lifting mechanism 3. A telescopic inner shaft 43 is movably engaged on the side of the flipping cylinder 42 near the flipping column 41. A limiting inner rod 421 is fixedly mounted in the middle of the flipping cylinder 42, and a portion of the telescopic inner shaft 43 is provided to cooperate with the limiting inner rod 421. The limiting slot 431 is used in conjunction with the limiting inner rod 421, which is movably engaged in the limiting slot 431 to facilitate the telescopic inner shaft 43 to slide telescopically within the tilting cylinder 42. When the two fixed rotating outer frames 61 are opposite to each other, the telescopic inner shaft 43 slides telescopically within the tilting cylinder 42. When the two fixed rotating outer frames 61 are close to each other, the telescopic inner shaft 43 slides telescopically within the tilting cylinder 42. When the tilting cylinder 42 rotates, it can drive the telescopic inner shaft 43 to rotate synchronously. The tilting column 41 and the telescopic inner shaft 43 are in phase. The back end is fixedly installed with the middle of the corresponding fixed frame 51; the opposite ends of the flip column 41 and the flip cylinder 42 are both fixedly fitted with driven worm gears 44, the side ends of the driven worm gears 44 are meshed with driving worm gears 45, the top and bottom ends of the driving worm gears 45 are rotatably mounted with rotating frames 451, the rotating frames 451 are fixedly installed with the first slide 33 and the second slide 34 respectively, and the first slide 33 and the second slide 34 are fixedly installed with a third motor 46 on the side near the driving worm gears 45. The driving end of the third motor 46 is coaxially fixedly installed with the top end of the corresponding driving worm gears 45. When in use, the third motors 46 on both sides are turned on, which synchronously drives the driving worm gears 45 on both sides to rotate, and then synchronously drives the driven worm gears 44 on both sides to rotate, and then synchronously drives the flip column 41, the flip cylinder 42 and the telescopic inner shaft 43 to rotate. With the connection of the fixed frame 51, the fixed rotation assembly 6 is driven to rotate 90 degrees, thereby driving the positioned graphite column to rotate stably 90 degrees.

[0046] The method of using the graphite electrode docking device includes the following steps:

[0047] Step 1: Control the activation of the third motors 46 on both sides, which synchronously drive the drive worm gears 45 on both sides to rotate, which in turn synchronously drive the driven worm wheels 44 on both sides to rotate, which in turn synchronously drive the tilting column 41, the tilting cylinder 42, and the telescopic inner shaft 43 to rotate. With the connection of the fixed frame 51, the fixed rotation assembly 6 is driven to rotate 90 degrees, with the fixed rotation assembly 6 facing vertically downward.

[0048] Step 2: Control the extension of the telescopic cylinder 54, and in conjunction with the connection of the connecting seat 53 and the fixed column 52, drive one of the fixed frames 51 away from the other fixed frame 51, causing the two fixed rotating outer frames 61 to move away from each other, and the telescopic inner shaft 43 to slide in the tilting cylinder 42.

[0049] Step 3: By controlling the activation of the second motors 38 on both sides, and cooperating with the transmission of the belt pulley transmission group 37 on both sides, multiple lifting screws 35 are driven to rotate synchronously, thereby driving the first slide block 33 and the second slide block 34 to descend vertically, thereby driving the fixed rotation component 6 to move down, and the middle position of the flat graphite column is moved to pass through the two fixed rotation outer frames 61 and placed between multiple positioning wheels 63. Then, the telescopic cylinder 54 is activated to retract, and in conjunction with the connection of the connecting seat 53 and the fixed column 52, one of the fixed frames 51 is driven to approach the other fixed frame 51, and the two fixed rotation outer frames 61 on both sides are driven to approach each other. The two fixed rotation outer frames 61 are combined to form a ring-shaped outer frame, the two horizontally corresponding semi-ring frames 64 are combined to form a ring-shaped frame, and the two semi-ring connecting frames 65 are combined to form a ring connecting frame.

[0050] Step 4: Synchronously control the start of the two-sided drive motors 672 to rotate, which drives the corresponding drive shafts 671 and drive gears 67 to rotate synchronously in the same direction, thereby driving the annular gear ring to rotate, which in turn drives the annular connecting frame to rotate. The annular frame rotates and engages with the planar threaded protrusion in the corresponding planar threaded groove, synchronously driving multiple positioning slides 62 and positioning wheels 63 to move towards each other, clamping and positioning the graphite column placed between the multiple positioning wheels 63.

[0051] Step 5: Move the entire fixed-rotation assembly 6 upward to clamp and position the graphite column. Then, flip the fixed-rotation assembly 6 again to reset it, so that the graphite column is in a vertical state. Then, turn on the linear electric rails 1 on both sides to drive the mounting base 2, lifting mechanism 3, flipping mechanism 4 and fixed-rotation mechanism 5 to translate the graphite column so that the graphite column and the graphite electrode are in the same position.

[0052] Step 6: Synchronous control turns on the first motors 633 on both sides to drive the transmission gears 634 to rotate, which in turn drives the rotating shafts 631 and positioning wheels 63 on both sides to rotate synchronously horizontally on the positioning slide 62, thereby driving the graphite column to rotate automatically horizontally. In conjunction with the downward movement of the entire fixed-rotation assembly 6 and the clamped and positioned graphite column, the graphite column is stably and spirally installed in the graphite electrode, saving time and effort.

[0053] Step 7: After the graphite column and graphite electrode are automatically aligned, the drive motors 672 on both sides are synchronously activated to rotate in opposite directions, driving the corresponding drive shafts 671 and drive gears 67 to rotate synchronously in opposite directions. This drives the annular gear ring to rotate in opposite directions, thereby driving the annular connecting frame to rotate in opposite directions. The annular frame rotates in opposite directions and engages with the planar threaded protrusion in the corresponding planar threaded groove. This synchronously drives multiple positioning slides 62 and positioning wheels 63 to move in opposite directions, causing the graphite column to lose its clamping and positioning. The fixed rotation outer frame 61, the semi-annular frame 64 and the semi-annular connecting frame 65 are reset, making it easy for the two fixed rotation outer frames 61 to separate and detach from the automatically aligned graphite column.

The side end of the driven worm gears (44) is meshed with a drive worm (45). The top and bottom ends of the drive worm (45) are rotatably mounted with rotating frames (451).

7. A graphite electrode docking device according to claim 1, characterized in that: The method of using the graphite electrode docking device includes the following steps: Step 1: Control the activation of the third motors (46) on both sides, which synchronously drive the drive worm gears (45) on both sides to rotate, which in turn synchronously drive the driven worm wheels (44) on both sides to rotate, which in turn synchronously drive the rotating column (41), rotating cylinder (42), and telescopic inner shaft (43) to rotate. With the connection of the fixed frame (51), the fixed rotation assembly (6) is driven to rotate 90 degrees, with the fixed rotation assembly (6) facing vertically downward. Step 2: Control the extension of the telescopic cylinder (54), and in conjunction with the connection of the connecting seat (53) and the fixed column (52), drive one of the fixed frames (51) away from the other fixed frame (51), causing the two fixed rotating outer frames (61) to move away from each other, and the telescopic inner shaft (43) to slide in the flipping cylinder (42); Step 3: By controlling the opening of the second motors (38) on both sides, and cooperating with the transmission of the belt pulley transmission group (37) on both sides, multiple lifting screws (35) are driven to rotate synchronously, thereby driving the first slide (33) and the second slide (34) to descend vertically, thereby driving the fixed rotation component (6) to move down, and the middle position of the flat graphite column is moved to pass through the two fixed rotation outer frames (61) and placed between multiple positioning wheels (63). Then, the telescopic cylinder (54) is opened to retract, and in cooperation with the connection of the connecting seat (53) and the fixed column (52), one of the fixed frames (51) is driven to approach the other fixed frame (51), driving the two fixed rotation outer frames (61) to approach each other. The two fixed rotation outer frames (61) are combined to form a ring outer frame, and the two horizontally corresponding half ring frames (64) are combined to form a ring frame, and the two half ring connecting frames (65) are combined to form a ring connecting frame. Step 4: Synchronously control the two drive motors (672) to rotate, which drives the corresponding drive shaft (671) and drive gear (67) to rotate synchronously in the same direction, thereby driving the ring gear to rotate, which in turn drives the ring connecting frame to rotate, and drives the ring frame to rotate. The ring frame is engaged with the planar thread protrusion in the corresponding planar thread groove, and synchronously drives multiple positioning slides (62) and positioning wheels (63) to move towards each other, clamping and positioning the graphite column placed between the multiple positioning wheels (63). Step 5: Move the entire fixed-rotation assembly (6) upwards to clamp and position the graphite column. Then, flip the fixed-rotation assembly (6) again to reset it, so that the graphite column is in a vertical state. Turn on the linear electric rails (1) on both sides to drive the mounting base (2), lifting mechanism (3), flipping mechanism (4) and fixed-rotation mechanism (5) to move the graphite column so that the graphite column and the graphite electrode are in the same position. Step 6: Synchronous control turns on the first motor (633) on both sides to drive the transmission gear (634) to rotate, thereby driving the rotating shaft (631) and positioning wheel (63) on both sides to rotate synchronously horizontally on the positioning slide (62), thereby driving the graphite column to rotate automatically horizontally. In conjunction with the entire fixed-rotation assembly (6) and the downward movement of the clamped and positioned graphite column, the graphite column is stably spirally installed in the graphite electrode, saving time and effort. Step 7: After the graphite column and graphite electrode are automatically docked, the drive motors (672) on both sides are turned on in reverse, which drives the corresponding drive shaft (671) and drive gear (67) to rotate in reverse synchronously, thereby driving the annular gear ring to rotate in reverse, which in turn drives the annular connecting frame to rotate in reverse, and drives the annular frame to rotate in reverse. The annular frame rotates in reverse, and the planar thread protrusion is engaged in the corresponding planar thread groove. The multiple positioning slides (62) and positioning wheels (63) are driven to move in opposite directions in a synchronous manner. The graphite column loses its clamping and positioning, and the fixed rotation outer frame (61), the half-ring frame (64) and the half-ring connecting frame (65) are reset, which makes it easy for the fixed rotation outer frames (61) on both sides to separate and detach from the graphite column after automatic docking.
