The second spring 543 is sleeved on the guide rod 541 and is located between the rear support 53 and the clamping mechanism 52.

[0038] In this embodiment, the two clamping members 524 are symmetrically arranged on both sides of the through hole, and the two ends of the driver 522 are respectively connected to the two clamping members 524 for driving the two clamping members 524 to move toward each other or away from each other.

[0039] In this embodiment, the penetration seat 523 includes two penetration plates arranged opposite to each other, the through holes are arranged through the two penetration plates, and the two clamping members 524 are both arranged between the two penetration plates.

[0040] In this embodiment, the clamping members 524 include a clamping claw and a connecting rod 525. The first fulcrum of the connecting rod 525 can be rotatably mounted on the penetration seat 523. The clamping claw is connected to the second fulcrum of the connecting rod 525. The third fulcrum of the connecting rod 525 is connected to the two ends of the driver 522. The driver 522 drives the two connecting rods 525 to move so that the clamping claw releases or clamps the operating rod 3.

[0041] In this embodiment, the driver 522 is a hydraulic cylinder or a pneumatic cylinder. The clamping mechanism 52 also includes a sliding sleeve 521, which is used to slide with the guide rod 541, allowing the clamping mechanism 52 to move back and forth along the guide rod 541.

When the operating rod 3 is taken, the walking trolley 44 of the furnace discharge equipment 4 walks along the track 6 to the calibrated position, and the rotating mechanism 45 drives the rock drilling track 43 to rotate a certain angle until the center of the rock drill 41 is aligned with the operating rod 3. The rock drilling trolley 42 moves along the rock drilling track 43, so that the operating rod 3 enters the guide sleeve 511. At the same time, the rotation function of the rock drill 41 is turned on, and the vibrating rod 411 rotates. When the rock drilling trolley 42 moves to the point where the thread of the vibrating rod 411 contacts the thread of the operating rod 3, it stops moving forward. The driver 522 is a hydraulic cylinder or an air cylinder, and its cylinder rod contracts, the clamping claws close, and the operating rod 3 is tightly held. The rotation of the thread of the vibrating rod 411 drives the compression spring of the operating rod 3 to continue to tighten until the thread is screwed to the bottom, completing the grasping of the operating rod 3. The pitching mechanism 56 of the furnace discharge equipment 4 is actuated, and the operating rod 3 is tilted up and returned to the center, completing the entire grasping process. On the contrary, when the operating rod needs to be unloaded, the driver 522 is a hydraulic cylinder or a pneumatic cylinder, the cylinder rod of which is extended, the clamping claws are opened, and the clamping mechanism 52 is reset under the action of the spring.

[0048] As can be seen from the above technical solution, the advantages and positive effects of the submerged arc furnace tapping equipment and the operating rod loading and unloading device of the present invention are:

[0049] In this embodiment, the front support 51 is used to introduce the operating rod 3, the rear support 53 passes through the operating rod 3, and the clamping mechanism 52 clamps the operating rod 3, thereby shortening the time for loading and unloading the operating rod 3, reducing the damage to the tool holder 1 caused by vibration, and reducing the damage to the furnace opening device 4 itself and the thread of the vibration rod 411 caused by long-term vibration of the furnace opening device 4 when loading and unloading the operating rod 3, thereby improving the service life of the furnace opening device 4.
