The first fitting 130 is partially disposed between the first and second position-limiting rings 150 and 160, and the first and second position-limiting rings 150 and 160 are used to prevent the first fitting 130 from moving along the axial direction of the new electrode 230, so as to ensure that the first fitting 130 can be stably fitted with the transmission assembly 120, thereby improving reliability.
Referring to fig. 2 and 3, in the present embodiment, the mounting frame 110 is provided with a first mounting cavity 111 and a second mounting cavity 112, the first mounting cavity 111 is used for mounting a first electrode 200 of the refining furnace, the second mounting cavity 112 is used for mounting a second electrode 210 of the refining furnace, and the first electrode 200 and the second electrode 210 cooperate to position the mounting frame 110, so as to position the transmission assembly 120 and ensure the matching accuracy of the first matching member 130 and the second matching member 140 with the transmission assembly 120. Before the electrode connecting operation, the first electrode 200 is installed in the first installation cavity 111, and the second electrode 210 is installed in the second installation cavity 112 to fix the relative positions of the mounting bracket 110 and the first and second electrodes 200 and 210, so that the first and second electrodes 200 and 210 can stably drive the mounting bracket 110 to ascend or descend along the axial directions of the first and second electrodes 200 and 210. However, the present invention is not limited thereto, and in other embodiments, the mounting block 110 may be only fixedly mounted on the first electrode 200, and the mounting block 110 may also be only fixedly mounted on the second electrode 210, which can also achieve the function of driving the mounting block 110 to ascend and descend, and the mounting position of the mounting block 110 is not particularly limited.

Specifically, in the refining furnace, the first electrode 200 and the second electrode 210 can be synchronously raised or lowered in the vertical direction (i.e., the axial direction of the first electrode 200 and the second electrode 210) under an electrically controlled operation. In the electrode connecting process, the first electrode 200 and the second electrode 210 are controlled to synchronously ascend or descend, so that the mounting frame 110 drives the transmission assembly 120 to ascend or descend, in the process, the spur rack 131 moves relative to the first gear assembly 121 to drive the first gear assembly 121 to rotate, and the first gear assembly 121 drives the annular rack 141 to rotate through the second gear assembly 122 and the transmission gear 123, so that the new electrode 230 rotates and is in threaded fit with the electrode 220 to be connected.
It should be noted that, in the process of screw-fitting the new electrode 230 with the electrode 220 to be connected, the new electrode 230 may be displaced downward along the vertical direction, but the displacement is very short, less than one centimeter, and will not affect the limit of the first limit ring 150 and the second limit ring 160 on the first fitting 130, and will not affect the engagement between the transmission gear 123 and the annular rack 141, and even will not affect the fitting between the straight rack 131 and the first gear assembly 121.

Specifically, the mounting ring 132 is disposed between the first limiting ring 150 and the second limiting ring 160, and the first limiting ring 150 and the second limiting ring 160 are used for preventing the mounting ring 132 from displacing along the axial direction of the new electrode 230, so as to ensure that the spur rack 131 can be stably matched with the first gear assembly 121 in the lifting process of the first electrode 200 and the second electrode 210.
The first stop collar 150 includes a first semicircular ring 151 and a second semicircular ring 152. The first semicircular ring 151 is fixedly connected with the second semicircular ring 152 through a bolt, and the first semicircular ring 151 and the second semicircular ring 152 are used for being sleeved outside the new electrode 230 together to fix the relative position of the first limiting ring 150 and the new electrode 230, prevent the first limiting ring 150 from displacing relative to the new electrode 230, and facilitate installation and disassembly.
In this embodiment, the specific structure of the second position-limiting ring 160 is the same as that of the first position-limiting ring 150, and is not described herein again.
