[0002] In industrial production processes such as metallurgy, electrolysis, and electric arc furnaces, the replacement and connection of electrodes are key links to ensure the normal operation of equipment. Since the electrodes are continuously consumed in a high-temperature and high-load environment, their lengths gradually shorten, and they need to be replaced and lengthened regularly. The existing electrode replacement methods usually rely on manual handling or mechanical auxiliary positioning. However, due to the long and heavy nature of the electrodes themselves, it is difficult to accurately dock them solely by manual or traditional mechanical methods, often resulting in unstable welding quality or uneven stress at the connection, thereby affecting the service life of the electrodes. In addition, manual handling and adjustment methods are not only time-consuming and laborious but also may affect the operation safety due to the high-temperature environment, further increasing the complexity of the replacement process.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1 - 10 , the present invention provides a technical solution for an electrode pushing device. Its detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0017] An electrode pushing device includes: a support component 1 and a fixed tube 2.

[0018] The two support components 1 are arranged symmetrically and spaced apart from each other to ensure the stable support of the fixed tube 2, while avoiding movement deviation caused by eccentricity or uneven force, improving the operation accuracy and reliability of the overall device, and realizing angle adjustment or position calibration during the electrode pushing process. The central position of the fixed tube 2 is connected to the support component 1 along the radial direction to ensure that the fixed tube 2 has a smaller force application requirement during the initial push.

[0019] The support component 1 includes: a support base 101, an inner end cap 103, a main spindle rod 104, an outer end cap 105, an auxiliary spindle rod 106, a sleeve 107, an inner gear 108, a connecting gear 109, a tooth ring 110 and an end gear 111.

[0020] The end face of the support base 101 is provided with an installation hole 102. The support base 101 is used to support the core structure of the entire device. The installation hole 102 on its end face provides a necessary installation reference for the fixation and rotation of the main shaft rod 104 and other components, ensuring the precise relative positions of the components during the operation of the device. The inner end cover 103 is fixedly installed at the bottom of the installation hole 102, serving as the reference surface for the installation of the main shaft rod 104 to ensure the axial stability of the main shaft rod 104. The main shaft rod 104 is rotatably arranged on the inner end cover 103 along the opening direction of the installation hole 102. The main shaft rod 104 is coaxially rotatably arranged on the support base 101 along the axial direction of the installation hole 102 and is stably supported by the inner end cover 103 to ensure smooth rotation under the action of the driving force and precise cooperation with the gear transmission mechanism. The outer end cover 105 is rotatably sleeved on the outer wall of the main shaft rod 104. The outer end cover 105 and the inner end cover 103 are rigidly connected by at least three auxiliary shaft rods 106, and the two remain stationary during the operation of the device, providing stable support for the movement of the main shaft rod 104 and the sleeve 107. At least three auxiliary shaft rods 106 are parallelly connected between the inner end cover 103 and the outer end cover 105, and at least three auxiliary shaft rods 106 are evenly arranged around the outside of the main shaft rod 104. The auxiliary shaft rods 106 form a stable connection between the outer end cover 105 and the inner end cover 103 and ensure that they are parallel to the main shaft rod 104 to provide good coaxiality, reduce vibration during rotation, and improve the overall accuracy of the transmission system. The sleeve 107 is rotatably arranged between the outer wall of the outer end cover 105 and the inner wall of the installation hole 102, and the distal end of the sleeve 107 away from the inner end cover 103 extends out of the support base 101 to ensure that the fixed tube 2 connected to the sleeve 107 can rotate smoothly. The internal gear 108 is arranged on the main shaft rod 104 and meshes with a plurality of connecting gears 109 as the central gear of the planetary gear mechanism to achieve power transmission. The tooth ring 110 is fixedly arranged on the inner wall of the sleeve 107 to form the external fixed gear of the planetary gear mechanism. The internal teeth of the tooth ring 110 mesh with the connecting gears 109 to provide a stable external meshing point. During the operation of the device, the tooth ring 110 rotates with the sleeve 107 and can drive the connecting gears 109 to rotate to achieve power transmission. The connecting gears 109 are rotatably arranged on the auxiliary shaft rods 106 and are located between the internal gear 108 and the tooth ring 110, acting as intermediate gears for power transmission. The two sides of the connecting gears 109 are respectively meshed with the internal gear 108 and the tooth ring 110 to achieve torque conversion and direction adjustment. The end gear 111 is arranged at the end of the main shaft rod 104 away from the inner end cover 103 to effectively transmit the rotational force of the main shaft rod 104 to the inner tube 22.

[0021] The fixed tube 2 includes: an outer tube 21, an inner tube 22, and a rack 23.

[0022] The outer tube 21 is connected to the sleeve 107. The end of the main spindle rod 104 extends into the inner cavity of the outer tube 21. The inner tube 22 is slidably arranged in the inner cavity of the outer tube 21 to realize the adjustable telescoping of the fixed tube 2. The rack 23 is arranged along the axial direction of the inner tube 22 on the outer wall of the inner tube 22. The rack 23 meshes with the end gear 111. The rotation of the end gear 111 can drive the rack 23 to move, thereby driving the inner tube 22 to move in the outer tube 21. The inner tube 22 adopts a replaceable design, enabling it to adapt to electrodes of different specifications, enhancing the applicable range of the device, and avoiding the need to replace the entire fixed tube 2 assembly due to changes in the electrode diameter.

[0023] The two support assemblies 1 are on the same horizontal plane. The two support assemblies 1 are installed on the same horizontal plane to ensure that the rotation axis of the fixed tube 2 remains horizontal, so as to ensure that the electrode does not tilt during rotation, affecting the docking accuracy.

[0024] The rotation angle of the fixed tube 2 is between 0° and 90°. The rotation angle of the fixed tube 2 is restricted between 0° and 90° to ensure that the electrode is convenient for handling and transportation at the horizontal position of 0°, and can be stably docked at the vertical position of 90°. Limiting the rotation angle prevents the fixed tube 2 from rotating excessively during operation, avoiding the misalignment or damage of the electrode connection caused by unnecessary movement.

[0025] There is an anti - detachment sleeve design between the sleeve 107 and the mounting hole 102. The anti - detachment sleeve design ensures that the sleeve 107 can only rotate around its own axis and will not displace or fall off in the axial direction, improving the safety and stability of the device. This anti - detachment design can adopt mechanical limit structures such as limit rings, retaining rings, axial snap - fasteners or embedded stoppers to prevent the sleeve 107 from slipping due to inertia or load changes during operation.

[0026] A number of balls are provided on the inner wall of the outer tube 21, and a rolling groove is provided on the outer wall of the inner tube 22. The number of balls and the rolling grooves are all distributed along the axis direction of the outer tube 21. The design of the cooperation between the balls and the rolling grooves can reduce the friction between the outer tube 21 and the inner tube 22, improve the smoothness of the sliding process, and extend the service life of the system.

[0027] Both the outer tube 21 and the inner tube 22 are divided into two halves along the radial vertical plane. The connection part of the outer tube 21 is connected through a connecting piece. One half of the outer tube 21 is fixedly connected to the sleeve 107. The split structure design of the outer tube 21 and the inner tube 22 is for the convenient placement and removal of the electrode, improving the installation and disassembly efficiency and reducing the difficulty of manual operation. Before installing the electrode, the outer tube 21 and the inner tube 22 are separated so that the electrode can be directly placed into the fixed tube 2 without complex insertion operations, improving the work efficiency. After the electrode is connected, the outer tube 21 and the inner tube 22 can be separated by disassembling the connecting piece, so that the fixed tube 2 and the electrode are separated, ensuring that the electrode can be taken out smoothly without being restricted by the outer tube 21 or the inner tube 22. Removable connecting pieces such as bolt connection, snap connection, magnetic connection or locking pin are used to ensure quick separation when needed, and at the same time provide sufficient structural strength in the connected state to prevent the fixed tube 2 from loosening during operation.

[0028] Guide plates 24 are mirror - set on the outer wall of each half of the inner tube 22. The guide plates 24 are distributed along the axial direction of the inner tube 22. Guide grooves are provided at the corresponding positions of the outer tube 21. The cooperation design of the guide plates 24 and the guide grooves can effectively disperse the pressure on the side of the rack 23, reduce the unilateral force during the meshing of the rack 23, improve the stability and service life of the inner tube 22. The guide plates 24 and the guide grooves are distributed along the axial direction of the inner tube 22 to ensure that the inner tube 22 always moves in a straight line during the sliding process, preventing unstable meshing or transmission loss of the rack 23 caused by deviation or shaking.

[0029] An electrode pushing device further includes: a base 31, a first top plate 41, a second top plate 5 and an adjusting device 6.

[0030] Base 31, a U-shaped groove 32 is formed on the top surface of the base 31, and both ends of the U-shaped groove 32 penetrate through the side wall of the base 31. The opening position of the U-shaped groove 32 ensures its symmetrical distribution on the vertical mid-plane of the base 31, ensuring the overall center of gravity of the device is balanced, so as to ensure the installation alignment of the fixed pipe 2 and related components, improving the overall stability and accuracy of the device. The shape and size of the U-shaped groove 32 match those of the fixed pipe 2 to adapt to the rotation of the fixed pipe 2, ensuring that there will be no excessive clearance or interference during the rotation process. A driving wheel (not shown in the figure) is provided at the bottom of the base 31. The setting of the driving wheel enables the device to move freely between different working areas, reducing the burden of manual handling and improving work efficiency. The U-shaped groove 32 divides the top surface of the base 31 into two independent areas. First electric push rods 33 are respectively arranged in the two independent areas. The first electric push rods 33 are all arranged in the direction perpendicular to the ground. A first top plate 41 and a second top plate 5 are respectively arranged on the first electric push rods 33 in the two independent areas. Controlling the telescoping of the first electric push rods 33 can change the heights of the first top plate 41 and the second top plate 5. The first electric push rods 33 can be selected from high-precision servo motors 81 or screw drives to ensure the consistency of the movement of the first top plate 41 and the second top plate 5. The opposite surfaces of the first top plate 41 and the second top plate 5 are both provided with sliding grooves, and an adjusting device 6 is installed in the sliding grooves. The shape and depth of the sliding grooves precisely match the installation requirements of the adjusting device 6, ensuring that the adjusting device 6 can move smoothly in the sliding grooves and providing sufficient supporting force.

[0031] The adjusting device 6 includes: a mounting member 61, a guide rod 62, a toothed plate 63, a worm 64, a transmission assembly 65, and a transmission rod 66.

[0032] The mounting member 61 is arranged in the sliding groove, the support assembly 1 is arranged on the mounting member 61, the guide rod 62 and the toothed plate 63 are respectively arranged on both sides of the mounting member 61, the guide rod 62 and the toothed plate 63 are located in the same extending direction, the extending direction of the guide rod 62 and the toothed plate 63 is perpendicular to the rotation axis of the fixed tube 2, and the end parts of the guide rod 62 and the toothed plate 63 are respectively inserted into the inner wall of the sliding groove. Cooperating with the guide rod 62 and the toothed plate 63, the sliding direction of the mounting member 61 in the sliding groove is restricted. The guide rod 62 and the rack 23 provide a linear guiding function, ensuring that the moving direction of the mounting member 61 along the sliding groove will not deviate, and improving the adjustment accuracy. A detachable connection method is adopted between the mounting member 61 and the support seat 101. The worm 64 is rotatably arranged on one side of the toothed plate 63, and the worm 64 meshes with the rack 23. The worm 64 has a transmission self-locking characteristic, preventing the toothed plate 63 from accidentally sliding due to external force influence, and improving the system safety. The combination of the toothed plate 63 and the worm 64 forms a stable transmission system. By rotating the worm 64, the movement of the toothed plate 63 is adjusted. The transmission rod 66 is rotatably installed on the first top plate 41 and the second top plate 5 in a direction perpendicular to the ground, and the transmission rod 66 is connected to the worm 64 through a transmission assembly 65. The transmission assembly 65 includes, but is not limited to, being connected by two bevel gears meshing. The transmission assembly 65 is used to connect the transmission rod 66 and the worm 64 to ensure stable power transmission. A spline opening is provided at the top end of the transmission rod 66. The vertical arrangement ensures that the guide rod 62 and the toothed plate 63 will not interfere with the rotational movement of the fixed tube 2. Among them, the inner cavities of the first top plate 41 and the second top plate 5 are provided with notches matching the adjusting device 6.

[0033] In order to ensure the synchronous operation of the adjusting devices 6 on the first top plate 41 and the second top plate 5, including but not limited to detachably installing a servo motor 81 at the spline opening of the transmission rods 66 of the two adjusting devices 6 to synchronously control the two transmission rods 66, so as to ensure that the mounting members 61 of the two adjusting devices 6 can move synchronously.

[0034] Two fixing devices 7 are arranged in parallel on the top surface of the first top plate 41 to fix the electrode when in a non-operating state. The fixing device 7 includes: a fixing block 71, a movable block 72, a second electric push rod 73 and a strap 74.

[0035] The fixed block 71 is fixedly installed on the top surface of the first top plate 41. The bottom corner of the proximal end of the movable block 72 away from the fixed block 71 is hinged to the first top plate 41. The distance between the fixed block 71 and the second top plate 5 is greater than the distance between the movable block 72 and the second top plate 5. The fixed block 71 and the movable block 72 have exactly the same structure. The clamping surfaces of the fixed block 71 and the movable block 72 match the outer shape of the electrode. The clamping surfaces are arc-shaped to ensure that they can fit the surface of the electrode, increase the contact area, and improve the fixing stability. At the same time, a receiving groove 42 is provided at the corresponding position of the movable block 72. After the movable block 72 rotates, it can completely move into the receiving groove 42. The second electric push rod 73 is arranged on the side wall of the first top plate 41. The extending end of the second electric push rod 73 extends into the receiving groove 42 and abuts against the side wall of the movable block 72. The first end of the strap 74 is detachably installed on the side wall of the movable block 72 and can enter the receiving groove 42 along with the movable block 72. The second end of the strap 74 is arranged on the side wall of one half of the inner tube 22. An opening window is provided on the side wall of the outer tube 21 for the strap 74 to pass through and be fixed to the side wall of the inner tube 22. The second end of the strap 74 is connected to one half of the inner tube 22 connected to the support assembly 1 on its side. At the same time, the position where the second end of the strap 74 is connected is on the side of the inner tube 22 away from the distal end of the fixed block 71. When the movable block 72 is in the receiving groove 42, the strap 74 is in a released state, and the strap 74 in one half of the inner tube 22 will fit the inner wall of the inner tube 22. When the movable block 72 is outside the receiving groove 42, the strap 74 is in a taut state.

[0036] A limiting device 8 is further arranged in the U-shaped groove 32. The limiting device 8 includes: a motor 81, a cable 82, a first stop block 83, and a second stop block 84.

[0037] The motor 81 is arranged at one end of the U-shaped groove 32 and is outside the rotation range of the fixed tube 2. One end of the cable 82 is connected to the output end of the motor 81, and the other end of the cable 82 is connected to the outer wall of the outer tube 21. The cable 82 can be wound by the rotation of the motor 81 to control the fixed tube 2 to rotate from the horizontal state to the vertical state. After the fixed tube 2 generates an initial deflection angle under manual force, it can continue to rotate under the action of gravity. The motor adjusts the tightness of the cable 82 to slow down its rotation speed and achieve a stable transition from the vertical to the horizontal. The first stop block 83 is arranged at a position close to the bottom end of the U-shaped groove 32. When the fixed tube 2 is in the vertical state, the outer wall of the fixed tube 2 contacts the first stop block 83 to limit the rotation angle of the fixed tube 2 to be greater than 90°. The second stop block 84 is arranged at a position close to the top of the U-shaped groove 32. When the fixed tube 2 is in the horizontal state, the outer wall of the fixed tube 2 contacts the second stop block 84 to limit the rotation angle of the fixed tube 2 to be less than 0°.

[0038] Working principle: First, place the electrode on two fixing devices 7. The second electric push rod 73 pushes the movable block 72 out of the receiving groove 42. The electrode is located between the fixed block 71 and the movable block 72. Remove half of the outer tube 21 connected to the sleeve 107. At the same time, connect the first end of the binding strap 74 to the side wall of the movable block 72. Move the electrode pushing device below the electrode to be connected. Rotate the fixed tube 2 to a horizontal state. Control the second electric push rod 73 to move the movable block 72 into the receiving groove 42. During this process, the movable block 72 will abut against the binding strap 74, and part of the binding strap 74 will move into the receiving groove 42 with the movable block 72. The binding strap 74 outside the receiving groove 42 is in a taut state. Then, slowly push the electrode towards the fixed tube 2. When the electrode moves out of the range covered by the movable block 72, control the movable block 72 to move out of the receiving groove 42, and at the same time, slightly move the electrode to prevent the electrode from moving into the fixed tube 2 before the binding strap 74 is taut. When the binding strap 74 is taut, move the electrode to the fixed tube 2. Since the binding strap 74 is in a taut state and the electrode is outside the fixed tube 2, then control the movable block 72 to slowly move into the receiving groove 42. Since the binding strap 74 is taut at the opening part of half of the inner tube 22, when the electrode rolls to this part of the inner tube 22, the binding strap 74 in the taut state will support the electrode and prevent it from entering the inner cavity of this part of the inner tube 22. As the binding strap 74 gradually relaxes, the electrode will slowly enter the fixed tube 2. When the electrode completely enters the fixed tube 2, remove the first end of the binding strap 74 from the side wall of the movable block 72 and place it on the outer wall of the electrode. Then, install the half of the outer tube 21 not connected to the sleeve 107 and the other half of the outer tube 21 on the outer wall of the electrode and fix them to form a complete fixed tube 2.Then, control the motor 81 to pull the cable 82 until the fixed tube 2 rotates to the vertical state, and the outer wall of the fixed tube 2 abuts against the first stopper 83. During the rotation of the fixed tube 2, the sleeve 107 rotates synchronously. Under the cooperation of the toothed ring 110, the connecting gear 109 and the internal gear 108, the main spindle rod 104 rotates in the opposite direction to the sleeve 107, and the end gear 111 rotates synchronously with the main spindle rod 104. Under the action of the end gear 111 and the rack 23, the inner tube 22 and the electrode will move towards the top of the fixed tube 2 until the fixed tube 2 rotates to the vertical state. At this time, the two adjusting devices 6 can be adjusted. Through external power, including but not limited to connecting two servo motors 81 to the two transmission rods 66 to synchronously drive the two transmission rods 66 to rotate. Under the cooperation of the worm 64 and the rack 23, control the position of the mounting member 61, thereby controlling the position of the two support assemblies 1, so as to finely adjust the position of the fixed tube 2. When the two electrodes are aligned, the first electric push rod 33 can be operated synchronously to control the heights of the first top plate 41 and the second top plate 5, so as to finely adjust the height of the fixed tube 2. After the two electrodes are aligned, the connection operation of the electrodes can be carried out. After completion, the half of the outer tube 21 and the inner tube 22 that are not connected to the sleeve 107 can be removed, and then the electrodes can be completely separated by moving the position of the base 31 or the mounting member 61, etc. At this time, the pushing and connection of the electrodes are completed.
