[0050] Reference Fig. 9 The present application also includes a limiting mechanism, which is arranged on one side of the graphite electrode body 113 so that it can assist in limiting the graphite electrode body 113. Two groups of support rods 411 are fixedly connected to the right side of the top of the bottom plate 111, and the tops of the support rods 411 are fixedly connected to a placement plate 412. The graphite electrode body 113 is placed on the surface of the placement plate 412, and a limiting plug plate 413 is inserted on the right side of the inside of the placement plate 412.

This design makes it easy to make the limiting plug plate 413 movable through the deformation of the fourth spring 414, so that the graphite electrode body 113 will not be affected during placement, and the limiting plug plate 413 can be used for limiting and auxiliary positioning after the subsequent placement is completed.

[0051] The implementation principle of a docking device for a graphite electrode joint in the embodiment of the present application is as follows:

[0052] First, when it is necessary to use a device to rotationally dock the graphite electrode pole head 112 and the graphite electrode body 113, the graphite electrode pole head 112 and the graphite electrode body 113 can be placed on the surface of the lower clamping ring 318 and the placement plate 412 respectively, and then the motor 215 and the electric push rod 324 can be controlled to work. When the motor 215 is working, it can drive the first pulley 216 to rotate. When the first pulley 216 rotates, it can drive the spline sleeve 214 to rotate through the transmission belt 218 and the second pulley 217. When the spline sleeve 214 rotates, it can drive the spline shaft 213 to rotate. When the spline shaft 213 rotates, since the spline shaft 213 is threadedly connected to the first threaded rod 212, the first threaded rod 212 cannot rotate, so that the spline shaft 213 moves to the outside of the spline sleeve 214, so that the spline shaft 213 moves to the side close to the graphite electrode pole head 112 and drives the second fixed rod 219 and the fixed sleeve plate 220 to rotate as a whole.

[0053] When the electric push rod 324 is working, it can drive the connecting plate 325 to move to the right side. When the connecting plate 325 moves, it can drive the first movable block 313 to move to the right side, so that the two sets of transmission gears 319 are respectively engaged with the two sets of second rack plates 328, so that the two-way threaded rods 314 on both sides rotate. When the two-way threaded rods 314 on both sides rotate, the threads on both sides of the two-way threaded rods 314 rotate in opposite directions and the movable blocks 315 cannot rotate, so that the movable blocks 315 on both sides move toward the side close to each other, and then the semicircular plate 316 and the clamping ring 318 move toward the side close to each other, so that the clamping ring 318 clamps the graphite electrode pole head 112, thereby completing the clamping limit of the graphite electrode pole head 112. At the same time, when the first movable block 313 moves, it will also squeeze the third spring 323, so that it deforms. At this time, the graphite electrode pole head 112 is at the end of the graphite electrode body 113 and fits with it.

[0054] Subsequently, when the fixed sleeve 220 rotates and moves toward the side close to the graphite electrode head 112, the rotating stop block 227 will abut against the graphite electrode head 112, thereby causing the second spring 229 to deform. Subsequently, when the rotating stop block 227 is placed outside the mounting groove on the graphite electrode head 112, the second spring 229 will restore its deformation so that the rotating stop block 227 is placed inside the mounting groove of the graphite electrode head 112. Since the fixed sleeve 220 and the movable plug block 224 are in a counterclockwise rotation state as a whole, the rotating stop blocks 227 on both sides can abut against the side walls of the connecting block 225, so that the movable plug block 224 and the rotating stop block 227 can be connected to the side wall of the connecting block 225. The block 227 can rotate as a whole and drive the graphite electrode pole head 112 to rotate and move. When the graphite electrode pole head 112 rotates, the second movable block 317 can rotate inside the semicircular plates 316 on both sides, thereby ensuring the normal rotation of the graphite electrode pole head 112, so that the graphite electrode pole head 112 can be screwed into the graphite electrode body 113. When the moving speed of the graphite electrode pole head 112 is different from the moving speed of the fixed sleeve 220 and the rotating block 227, the movable plug 221 can be moved inside the fixed sleeve 220, so that the first spring 222 is deformed, and then adaptive adjustment is performed.

[0055] When the graphite electrode pole head 112 is screwed into the graphite electrode body 113, the graphite electrode pole head 112, the clamping ring 318 and the bidirectional threaded rod 314 move to the right as a whole. At this time, the transmission gears 319 on both sides will respectively mesh with the second rack plates 328 on both sides. Since the transmission belts 218 on both sides are on the other side of the two sets of transmission gears 319, the two sets of transmission gears 319 will rotate to the other side, so that the movable blocks 315 on both sides move away from each other and drive the clamping ring 318 and the semicircular plate 316 to move away from each other, thereby releasing the clamping limit of the graphite electrode pole head 112 and ensuring the normal screwing and docking of the graphite electrode pole head 112. When the clamping ring 318 releases the clamping of the graphite electrode pole head 112, the clamping ring 318 will not rotate at this time, so that the magnet 326 on the clamping ring 318 is attracted to the magnetic strip 327, thereby limiting the clamping ring 318.

[0056] Subsequently, when the graphite electrode pole head 112 is docked, the motor 215 can be controlled to reverse and the electric push rod 324 can be reset, so that the rotating blocks 227 on both sides rotate to the other side. At this time, the rotating blocks 227 cannot abut against the movable plug block 224, so that the rotating blocks 227 are screwed out from the inside of the graphite electrode pole head 112, and the torsion spring 228 is deformed. When the motor 215 is reversed, the spline shaft 213 can be moved toward the inside of the spline sleeve 214, thereby performing a reset operation. When the rotating blocks 227 are moved out of the graphite electrode pole head 112, the third spring 323 can also restore the deformation of the third spring 323 to drive the first movable block 313 to reset, and at the same time, the clamp ring 318 and the semicircular plate 316 are reset, thereby completing the reset of the device.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
