Description

Technical Field

[0001] The present invention relates to the technical field of handling equipment, in particular to an electrode pushing device. Background Art

[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. Due to the continuous consumption of electrodes in high temperature and high load environments, their length gradually shortens and they need to be replaced and lengthened regularly. Existing electrode replacement methods usually rely on manual handling or mechanically assisted positioning. However, since the electrodes themselves are long and heavy, it is difficult to accurately connect them by manual or traditional mechanical methods alone, which often leads to unstable welding quality or uneven force at the connection, thereby affecting the service life of the electrodes. In addition, manual handling and adjustment methods are not only time-consuming and labor-intensive, but may also affect operational safety due to high temperature environments, further increasing the complexity of the replacement process. These methods have certain limitations in practical applications, including complex operations, low positioning accuracy, high labor intensity and insufficient safety. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figures 1-10 The present invention provides a technical solution for an electrode pushing device. The detailed connection means are well known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0043] An electrode pushing device includes: a support component 1 and a fixing tube 2.

[0044] The two support assemblies 1 are arranged in a symmetrical manner and spaced apart from each other to ensure stable support of the fixed tube 2, while avoiding movement deviation caused by eccentricity or uneven force, improving the operating accuracy and reliability of the overall device, and realizing angle adjustment or position calibration during the electrode pushing process. The center position of the fixed tube 2 is radially connected to the support assembly 1 to ensure that the fixed tube 2 has a smaller force requirement during the initial push.

[0045] The support assembly 1 includes: a support base 101, an inner end cover 103, a main shaft 104, an outer end cover 105, a secondary shaft 106, a sleeve 107, an internal gear 108, a connecting gear 109, a gear ring 110 and an end gear 111.

[0046] The support base 101 has a mounting hole 102 on its end face. The support base 101 is used to support the core structure of the entire device. The mounting hole 102 on its end face provides the necessary mounting reference for the fixation and rotation of the main shaft 104 and other components, ensuring the accurate relative position of each component during the operation of the device. The inner end cover 103 is fixedly mounted on the bottom of the mounting hole 102, serving as the reference surface for the installation of the main shaft 104, ensuring the axial stability of the main shaft 104. The main shaft 104 is rotatably arranged on the inner end cover 103 along the opening direction of the mounting hole 102. The main shaft 104 is coaxially rotatably arranged on the support base 101 along the axial direction of the mounting hole 102, and is provided with stable support by the inner end cover 103, ensuring that it can rotate smoothly under the action of the driving force and accurately cooperate with the gear transmission mechanism. The outer end cover 105 is rotatably sleeved on the outer wall of the main shaft 104. The outer end cover 105 and the inner end cover 103 are rigidly connected by at least three secondary shafts 106, and both remain stationary during the operation of the device. The main shaft 104 and the sleeve 107 are immovable, providing stable support for the movement of the main shaft 104 and the sleeve 107. At least three secondary shafts 106 are connected in parallel between the inner end cover 103 and the outer end cover 105, and at least three secondary shafts 106 are evenly surrounded on the outside of the main shaft 104. The secondary shaft 106 forms a stable connection between the outer end cover 105 and the inner end cover 103, and ensures that it is parallel to the main shaft 104 to provide good coaxiality, reduce vibration during rotation, and improve the overall accuracy of the transmission system. The sleeve 107 is rotatably set on the outer wall of the outer end cover 105 and the installation The inner wall of the mounting hole 102 is provided, and the sleeve 107 extends out of the outside of the support seat 101 from the far end of the inner end cover 103 to ensure that the fixed tube 2 connected to the sleeve 107 can rotate smoothly. The internal gear 108 is provided on the main shaft 104 and meshes with multiple connecting gears 109 as the central gear of the planetary gear mechanism to achieve power transmission. The gear ring 110 is fixedly provided on the inner wall of the sleeve 107 to form an external fixed gear of the planetary gear mechanism. The internal teeth of the gear ring 110 mesh with the connecting gears 109 to provide a stable external meshing point. During the operation of the device, the gear ring 110 rotates with the sleeve 107, which can drive the connecting gear 109 to rotate to realize power transmission. The connecting gear 109 is rotatably set on the secondary shaft 106, located between the internal gear 108 and the gear ring 110, acting as an intermediate gear for power transmission. The two sides of the connecting gear 109 are respectively engaged with the internal gear 108 and the gear ring 110 to realize torque conversion and direction adjustment. The end gear 111 is set at the end of the main shaft 104 away from the inner end cover 103, so that the rotational force of the main shaft 104 is effectively transmitted to the inner tube 22.

[0047] The fixed tube 2 includes an outer tube 21 , an inner tube 22 and a rack 23 .

[0048] The outer tube 21 is connected to the sleeve 107, the end of the main shaft 104 extends to the inner cavity of the outer tube 21, and the inner tube 22 is slidably set in the inner cavity of the outer tube 21 to realize the adjustable extension and retraction of the fixed tube 2. The rack 23 is axially arranged on the outer wall of the inner tube 22 along the inner tube 22, and the rack 23 is engaged 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, so that it can adapt to electrodes of different specifications, enhance the applicability of the device, and avoid the need to replace the entire fixed tube 2 assembly due to changes in electrode diameter.

[0049] 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 to ensure that the electrode does not tilt during rotation, affecting the docking accuracy.

[0050] The rotation angle of the fixed tube 2 is between 0° and 90°. The rotation angle of the fixed tube 2 is limited between 0° and 90° to ensure that the electrode is easy to carry and transport when in the horizontal position of 0°, and can be stably docked when in the vertical position of 90°. Limiting the rotation angle prevents the fixed tube 2 from excessive rotation during operation, avoiding misalignment or damage of the electrode connection due to unnecessary movement.

[0051] There is an anti-slip design between the sleeve 107 and the mounting hole 102. The anti-slip design ensures that the sleeve 107 can only rotate around its own axis and will not be displaced or fall off in the axial direction, thereby improving the safety and stability of the device. The anti-slip design can adopt a mechanical limiting structure, such as a limiting ring, a retaining ring, an axial clip or an embedded stopper to prevent the sleeve 107 from slipping due to inertia or load changes during operation.

[0052] A plurality 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 plurality of balls and rolling grooves are distributed along the axial direction of the outer tube 21. The ball and rolling groove matching design can reduce the friction between the inner and outer tubes 21, improve the smoothness of the sliding process, and extend the service life of the system.

[0053] The outer tube 21 and the inner tube 22 are both divided into two halves along the radial vertical plane. The connection of the outer tube 21 is connected by a connector, and half of the outer tube 21 is fixedly connected to the sleeve 107. The split structure of the outer tube 21 and the inner tube 22 is designed for convenient placement and removal of the electrode, improving the efficiency of installation and disassembly, and reducing the difficulty of manual operation. Before the electrode is installed, the outer tube 21 and the inner tube 22 are separated so that the electrode can be directly placed in the fixed tube 2 without the need for complicated insertion operations, thereby improving work efficiency. After the electrode is connected, the outer tube 21 and the inner tube 22 can be separated by removing the connector, thereby separating the fixed tube 2 from the electrode, ensuring that the electrode can be smoothly removed without being restricted by the outer tube 21 or the inner tube 22. Removable connectors such as bolt connections, snap-on connections, magnetic connections or locking pins are used to ensure that they can be quickly separated when needed, and at the same time, they can provide sufficient structural strength in the connected state to prevent the fixed tube 2 from loosening in the working state.

[0054] A guide plate 24 is mirrored on the outer wall of each half of the inner tube 22. The guide plates 24 are distributed axially along the inner tube 22. A guide groove is provided at the corresponding position of the outer tube 21. The coordinated 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 due to the engagement of the rack 23, and improve the stability and service life of the inner tube 22. The guide plates 24 and the guide grooves are distributed axially along the inner tube 22 to ensure that the inner tube 22 always maintains linear motion during the sliding process, thereby preventing unstable engagement of the rack 23 or transmission loss due to offset or shaking.

[0055] An electrode pushing device further includes: a base 31 , a first top plate 41 , a second top plate 5 and an adjusting device 6 .

[0056] The base 31 has a U-shaped groove 32 on its top surface, and both ends of the U-shaped groove 32 pass through the side walls of the base 31. The U-shaped groove 32 is positioned to ensure that it is symmetrically distributed on the vertical mid-plane of the base 31, ensuring that the overall center of gravity of the device is balanced, so as to ensure the installation alignment of the fixed tube 2 and related components, and improve the overall stability and accuracy of the device. The shape and size of the U-shaped groove 32 match the fixed tube 2 to adapt to the rotation of the fixed tube 2, ensuring that no excessive gap or interference is generated during the rotation process. A driving wheel is provided at the bottom of the base 31, which is not shown in the figure. The setting of the driving wheel can enable the device to move freely between different working areas, reduce the burden of manual handling, and improve work efficiency. The U-shaped groove 32 divides the top surface of the base 31 into two independent There are two independent areas, and the two independent areas are respectively provided with a first electric push rod 33. The first electric push rods 33 are both arranged in a direction perpendicular to the ground. The first top plate 41 and the second top plate 5 are respectively arranged on the first electric push rods 33 of the two independent areas. Controlling the extension and retraction of the first electric push rod 33 can change the height of the first top plate 41 and the second top plate 5. The first electric push rod 33 can be driven by a high-precision servo motor 81 or a screw 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 provided with a slide groove, and an adjusting device 6 is installed in the slide groove. The shape and depth of the slide groove precisely match the installation requirements of the adjusting device 6, ensuring that the adjusting device 6 can move smoothly in the slide groove and provide sufficient supporting force.

[0057] The adjusting device 6 includes a mounting member 61 , a guide rod 62 , a tooth plate 63 , a worm 64 , a transmission assembly 65 and a transmission rod 66 .

[0058] The mounting member 61 is arranged in the slide groove, the support assembly 1 is arranged on the mounting member 61, the guide rod 62 and the tooth plate 63 are respectively arranged on both sides of the mounting member 61, the guide rod 62 and the tooth plate 63 are located in the same extension direction, the extension direction of the guide rod 62 and the tooth plate 63 are perpendicular to the rotation axis of the fixed tube 2, and the ends of the guide rod 62 and the tooth plate 63 are respectively inserted into the inner wall of the slide groove, cooperating with the guide rod 62 and the tooth plate 63 to limit the sliding direction of the mounting member 61 in the slide groove, and the guide rod 62 and the rack 23 provide a linear guiding function to ensure that the mounting member 61 will not deviate along the movement direction of the slide groove, thereby improving the adjustment accuracy. The mounting member 61 and the support seat 101 are connected in a detachable manner. The worm 64 is rotatably arranged on one side of the tooth plate 63, and the worm 64 is meshed with the rack 23. The self-locking feature of the worm 64 prevents the tooth plate 63 from accidentally sliding due to external force, thereby improving the safety of the system. The combination of the tooth plate 63 and the worm 64 forms a stable transmission system. The movement of the tooth plate 63 is adjusted by the rotation of the worm 64. The transmission rod 66 is rotatably mounted on the first top plate 41 and the second top plate 5 in a direction perpendicular to the ground, and the transmission rod 66 and the worm 64 are connected by a transmission assembly 65. The transmission assembly 65 includes but is not limited to the use of two bevel gear meshing connections. The transmission assembly 65 is used to connect the transmission rod 66 and the worm 64 to ensure stable power. A spline mouth is provided at the top of the transmission rod 66, and the vertical arrangement ensures that the guide rod 62 and the tooth plate 63 will not interfere with the rotational movement of the fixed pipe 2. The inner cavity of the first top plate 41 and the second top plate 5 is provided with a slot matching the adjustment device 6.

[0059] In order to ensure the synchronous operation of the adjusting devices 6 on the first top plate 41 and the second top plate 5, it is included but not limited to using a servo motor 81 that can be detachably installed at the spline mouth of the transmission rods 66 of the two adjusting devices 6 to synchronously control the two transmission rods 66 to ensure that the mounting parts 61 of the two adjusting devices 6 can move synchronously.

[0060] Two fixing devices 7 are provided in parallel on the top surface of the first top plate 41 to fix the electrode when in a non-operating state, wherein the fixing device 7 includes: a fixed block 71 , a movable block 72 , a second electric push rod 73 and a binding belt 74 .

[0061] The fixed block 71 is fixedly installed on the top surface of the first top plate 41, and the bottom corner of the movable block 72 near the proximal end of the fixed block 71 is hinged on 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 shape of the electrode. The arc-shaped clamping surface ensures that it can fit the electrode surface, increase the contact area, and improve the fixing stability. At the same time, an accommodating groove 42 is opened at the corresponding position of the movable block 72. After rotation, the movable block 72 can be completely moved into the accommodating groove 42. The second electric push rod 73 is arranged on the side wall of the first top plate 41, and the protruding end of the second electric push rod 73 extends into the accommodating groove 42 and abuts against the side wall of the movable block 72. The first end of the strap 74 is detachably mounted on the side wall of the movable block 72 and can enter the accommodating groove 42 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, and 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 the half of the inner tube 22 connected to the side support assembly 1 where it is located. At the same time, the position where the second end of the strap 74 is connected is the side of the inner tube 22 far away from the fixed block 71, so that when the movable block 72 is in the accommodating groove 42, the strap 74 is in a released state, and the strap 74 located in half of the inner tube 22 will fit the inner wall of the inner tube 22. When the movable block 72 is outside the accommodating groove 42, the strap 74 is in a taut state.

[0062] A limiting device 8 is further provided in the U-shaped groove 32 . The limiting device 8 includes a motor 81 , a cable 82 , a first stopper 83 and a second stopper 84 .

[0063] The motor 81 is arranged at one end of the U-shaped groove 32, and the motor 81 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 rotation of the motor 81 can be used to wrap around the cable 82 to control the rotation of the fixed tube 2 from a horizontal state to a 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 slowly release its rotation speed to achieve a stable transition from vertical to horizontal. The first stop block 83 is arranged near 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 greater than 90°. The second stop block 84 is arranged near the top end 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 less than 0°.

[0064] Working principle:

[0065] The second electric push rod 73 is used to push the movable block 72 out of the receiving groove 42, and the electrode is located between the fixed block 71 and the movable block 72. The half of the outer tube 21 connected to the sleeve 107 is removed, and the first end of the strap 74 is connected to the side wall of the movable block 72. The electrode pushing device is moved to the bottom of the electrode to be connected, and the fixed tube 2 is rotated to a horizontal state. The second electric push rod 73 is controlled to move the movable block 72 into the receiving groove 42. During this process, the movable block 72 will abut against the strap 74, and part of the strap 74 will move into the receiving groove 42 with the movable block 72. The strap 74 outside the receiving groove 42 is in a taut state. Then the electrode is slowly pushed toward the fixed tube 2. When the electrode is out of the range covered by the movable block 72, the movable block 72 is controlled to move out of the receiving groove 42, and at the same time, it is slightly moved. Move the electrode to prevent the electrode from moving into the fixed tube 2 before the band 74 is tightened. When the band 74 is tightened, move the electrode to the fixed tube 2. Since the band 74 is in a tightened state, the electrode is outside the fixed tube 2. Then control the movable block 72 to move slowly into the accommodating groove 42. Since the band 74 is tightened at the opening part of half of the inner tube 22, when the electrode rolls to this part of the inner tube 22, the band 74 in a tightened state will support the electrode from entering the inner cavity of this part of the inner tube 22. As the band 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 band 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 that is 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 and pull the cable 82 until the fixed tube 2 rotates to a 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. With the cooperation of the gear ring 110, the connecting gear 109 and the inner gear 108, the main shaft 104 and the sleeve 107 rotate in opposite directions, and the end gear 111 rotates synchronously with the main shaft 104. Under the action of the end gear 111 and the rack 23, the inner tube 22 will move with the electrode toward the top direction of the fixed tube 2 until the fixed tube 2 rotates to a vertical state. At this time, the two adjustment devices 6 can be adjusted, which can be achieved by external power, including but not limited to connecting the two servo motors 8 on the two transmission rods 66. 1. Synchronously drive the two transmission rods 66 to rotate, and with 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. After the two electrodes are aligned, the first electric push rod 33 can be synchronously operated to control the height of the first top plate 41 and the second top plate 5, so as to achieve fine adjustment of the height of the fixed tube 2. After the two electrodes are aligned, the electrode connection operation can be carried out.
