Description

Technical Field

[0001] The invention relates to the technical field of graphite electrodes, in particular to a docking mechanism for graphite electrode joints. Background Art

[0002] Graphite electrode refers to a high-temperature conductive material made from petroleum coke and needle coke as the main raw materials and coal tar as the binder, through calcination, molding, roasting, graphitization and other processes. It is widely used in electric arc furnace steelmaking and other fields. Graphite electrodes are connected through electrode joints. Existing graphite electrode rods and electrode joints are usually connected in a spiral manner. The electrode joint adopts a conical or cylindrical thread structure, and is physically fixed by tightening the male head (joint) and the female head (electrode hole groove).

[0003] The utility model with announcement number CN215036862U discloses a docking device for graphite electrode joints. By starting the servo motor, the two clamping blocks are eventually driven to approach each other and clamp the graphite electrode joint body. After clamping, the handle is turned, and the graphite electrode joint body is finally rotated while moving laterally toward the spare graphite electrode. The graphite electrode joint body can then be threadedly connected to the electrode hole to complete the installation of the graphite electrode joint body.

[0004] The utility model with announcement number CN215548206U discloses a limiting device for assembling a carbon-carbon ring and a graphite electrode. It is provided with a clamping seat and a limiting plate. By the mutual approach of the first slide and the second slide, the bracket and the sleeve can be elastically extended and retracted, so that the limiting plate can rotate under the support of the push rod, so that the limiting plate can fit the inner wall of the carbon ring, and then push the carbon ring to move and splice and assemble with the graphite electrode. At the same time, the first slide will pull the clamping seat to rotate through the pull rope, so that the clamping block can stably clamp the graphite electrode.

[0005] However, the docking device for graphite electrode joints disclosed above still has the following problems during actual use: the graphite electrode column and the electrode joint are placed horizontally and locked by rotation, but due to the high precision requirements for docking between the graphite electrode column and the joint, graphite debris on the surface of the graphite electrode column and the joint will cause wear during the rotational docking process, thereby affecting the tightness of the connection between the graphite electrode column and the joint, and also causing the electrode joint to tilt and cause damage, thus resulting in docking failure and affecting the high-temperature conductive effect.

[0006] Therefore, we propose a docking mechanism for graphite electrode joints in order to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a docking mechanism for a graphite electrode joint, in order to solve the problem that the existing method is to place the graphite electrode column and the electrode joint horizontally and lock them by rotation. However, due to the high precision requirements for the docking between the graphite electrode column and the joint, the graphite debris on the surface of the graphite electrode column and the joint will cause wear during the rotational docking process, thereby affecting the tightness of the connection between the graphite electrode column and the joint, and also causing the electrode joint to tilt and cause damage, thus leading to docking failure and affecting high-temperature conductivity.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a docking mechanism for a graphite electrode joint, comprising a bearing base and a bidirectional threaded rod rotatably mounted at the center of the bearing base; and further comprising:

[0011] A docking mechanism is provided on the right side of the top surface of the supporting base, and the docking mechanism includes a docking bracket, and a rotating sleeve is rotatably provided at the inner center position of the docking bracket.

[0015] Preferably, the bottom end of the pressing slide included in the positioning mechanism is slidably arranged inside the positioning slide, and the pressing slide and the positioning slide are distributed one-to-one in reverse order, and the graphite electrode rod is clamped and limited by the pressing slide, the positioning slide and the inner limiting arc plate, and the bottom end of the positioning slide is threadedly connected to the left end of the bidirectional threaded rod inside the supporting base.

[0016] Preferably, the dust removal mechanism includes a limiting slide rod, and the limiting slide rod is fixedly installed on the front and rear sides of the supporting base, and the limiting slide rod slides through the bottom end of the symmetrically arranged dust removal bracket, and the limiting slide rod and the bottom end of the dust removal bracket are connected to each other through a torsion spring, and at the same time, the front and rear sides of the supporting base are fixedly installed with a resisting inclined plate.

[0017] Preferably, the dust removal mechanism includes a resistance inclined plate and a dust removal bracket in the initial position, which are far away from each other, and the resistance inclined plate is arranged in an inclined structure on the side close to the dust removal bracket. The dust removal bracket and the resistance inclined plate slide in contact with each other, so that the inclined surface of the resistance inclined plate squeezes the dust removal bracket to drive the dust removal turntable at the top to rotate outward, so that the dust removal turntable is disengaged from the positioning mechanism and the docking mechanism.

[0018] Preferably, the dust removal mechanism includes an elastic airbag installed on the front and rear sides of the supporting base, and the elastic airbag realizes extrusion air supply through the movement of the positioning mechanism and the docking mechanism, and the elastic airbag and the dust removal turntable are connected through a conveying pipe, and the corresponding electrode rod and electrode joint are dusted through the dust removal turntable.

[0019] Preferably, the dust removal mechanism includes a worm gear block fixedly mounted at an equal angle on the outer wall of the dust removal turntable, and the worm gear block is meshedly connected with the outer driving worm, and the upper end bearing of the driving worm is rotatably arranged on the outer wall of the dust removal bracket, and the bottom end of the driving worm is fixedly mounted with a guide gear, and the guide gear extends to the interior of the bearing base;

[0020] The dust removal mechanism includes guide tooth blocks fixedly installed on the front and rear sides of the supporting base, and the guide tooth blocks are meshed and connected with the guide gear at the bottom end of the dust removal bracket, and the guide gear and the guide tooth block are meshed and disengaged by flipping the dust removal bracket, and when the dust removal bracket is pushed by the positioning mechanism and the docking mechanism, the guide gear meshes with the guide tooth block to rotate.

[0021] Preferably, the docking mechanism includes a docking bracket threadedly connected to the right outer wall of the bidirectional threaded rod inside the supporting base, and the electrode connector is threadedly installed in the rotating sleeve inside the docking bracket, and the rotating sleeve is driven to rotate by the motor at the rear so that the electrode connector and the electrode rod are rotated when they move into place to achieve docking installation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the docking mechanism of the graphite electrode joint adjusts the distance between the graphite electrode rod and the electrode joint through the positioning mechanism and the docking mechanism, so that the dust removal bracket and the dust removal turntable of the dust removal mechanism clean the inner cavity and the outer wall, and after moving into position, they are flipped without affecting the docking, so as to improve the convenience and accuracy of the docking between the graphite electrode rod and the electrode joint. The specific contents are as follows:

[0023] 1. Graphite electrode rods of different specifications are placed on top of the positioning bracket. The positioning pressure plate is driven down by its own weight to tighten the traction cable so that the positioning slides on the front and rear sides slide inward synchronously, so that the limit arc plate contacts the bottom outer wall of the graphite electrode rod, thereby preventing the graphite electrode rods of different specifications from being displaced during positioning.

[0024] Furthermore, the limiting arc plate squeezes the graphite electrode rod and then slides outward, driving the positioning rack connected to the resistance spring to rotate the meshing positioning gear. After the positioning gear drives the lifting threaded rod to rotate, it drives the pressure-covering slide on the top of the positioning slide to slide downward, and then the pressure-covering slide is attached to the top of the graphite electrode rod to ensure stability during the subsequent docking process.

[0025] 2. Electrode connectors of different specifications are connected to the corresponding spinning sleeves in a spiral manner, and the spinning sleeve is installed above the docking bracket, so that the bidirectional threaded rod inside the supporting base drives the threaded positioning brackets and the docking bracket on the left and right sides to slide inward synchronously, and then the graphite electrode rod and the electrode connector are docked and adjusted in distance, so that the electrode connector is driven by the spinning sleeve to be rotated and installed inside the graphite electrode rod.

[0026] 3. The graphite electrode rod and the electrode joint drive the fitted dust removal turntable and the dust removal bracket to move synchronously. The positioning bracket and the docking bracket squeeze the fitted elastic airbag, so that the elastic airbag conveys air to the interior of the dust removal turntable through the through-connected conveying pipe, so as to blow and remove dust from the inner cavity of the graphite electrode rod and the surface of the electrode joint.

[0027] Furthermore, the movable dust removal bracket drives the guide gear at the bottom end of the driving worm to engage with the guide tooth block, so that the rotating driving worm engages with the worm gear block and drives the dust removal turntable to rotate, so that the dust removal turntable is within the dust removal range, avoiding the residual graphite debris from affecting the docking.

[0028] When the dust removal bracket moves, it fits in with the interference inclined plate, and the inclined surface structure gradually interferes with the moving bracket, causing it to drive the dust removal turntable to rotate outward, thereby breaking away from the fit between the graphite electrode rod and the electrode joint, avoiding obstruction during the docking process, and improving the convenience and accuracy of the docking between the graphite electrode rod and the electrode joint.

[0044] like Figure 7-10 As shown, during the docking process, the graphite electrode rod is placed between the positioning slides 4 on the front and rear sides above the positioning bracket 3, and the graphite electrode rod slides downward against the positioning pressure plate 9, and the positioning pressure plate 9 drives the traction cable 10 connected to the bottom end to be tensioned, so that the traction cable 10 drives the positioning slide 4 fixed at the outer end to slide inward, and the positioning is achieved by the dead weight of the graphite electrode rods of different specifications.

[0045] Furthermore, the positioning slide 4 that moves inward contacts the outer wall of the bottom surface of the graphite electrode rod through the inner limiting arc plate 11, so that the squeezed limiting arc plate 11 drives the positioning rack 12 connected to the resistance spring 13 to slide outward, and the positioning gear 14 engaged with the positioning rack 12 rotates inside the positioning slide 4, so that the positioning gear 14 drives the lifting threaded rod 15 to be threadedly connected with the pressing slide 16, and the pressing slide 16 is limited by the positioning slide 4 so that the pressing slide 16 can slide downward and fit the upper outer wall of the graphite electrode rod to avoid displacement during subsequent docking.

[0049] The dust removal mechanism includes a resistance inclined plate 19 which is far away from the dust removal bracket 5 in the initial position, and the resistance inclined plate 19 is arranged in a slanted structure on the side close to the dust removal bracket 5. The dust removal bracket 5 and the resistance inclined plate 19 slide together, so that the inclined surface of the resistance inclined plate 19 squeezes the dust removal bracket 5 to drive the dust removal turntable 6 at the top to rotate outward, so that the dust removal turntable 6 is separated from the positioning mechanism and the docking mechanism; the dust removal mechanism includes an elastic airbag 20 installed on the front and rear sides of the supporting base 1, and the elastic airbag 20 is squeezed and supplied with air through the movement of the positioning mechanism and the docking mechanism, and the elastic airbag 20 is connected to the dust removal turntable 6 through a conveying pipe 21, and the corresponding electrode rod and electrode joint are dusted through the dust removal turntable 6.

[0052] Furthermore, during the movement of the dust removal bracket 5, the driving worm 23 installed on the outside of the dust removal bracket 5 is rotated to engage the guide gear block 25 set inside the supporting base 1 through the guide gear 24 at the bottom, so as to drive the worm 23 to rotate and engage the worm gear block 22 on the outer wall of the dust removal turntable 6, so that the dust removal turntable 6 cooperates with the internal dust removal nozzle to improve the dust removal effect through rotation, thereby avoiding the residue of graphite debris.

[0053] like Figure 3-Figure 5As shown, during the movement of the dust removal bracket 5 on the front and rear sides of the supporting base 1, the dust removal bracket 5 is guided by the inclined surface between the symmetrically arranged interference inclined plates 19 and the dust removal bracket 5, so that the dust removal bracket 5 is resisted and flipped outward, while driving the torsion spring 18 to twist. The torsion spring 18 can drive the dust removal bracket 5 to flip while sliding it back to its initial position.
