[0041] In one embodiment, the left and right sides of the substrate 21 are provided with fixing blocks 212 for limiting the moving distance of the translation mechanism 41, and the substrate 21 is also provided with a positioning sensor 213 for detecting the position of the short column 462.

[0042] As one implementation method, such as Figure 9 As shown, the positioning component 46 includes a second electric cylinder 461 and a short column 462. The second electric cylinder 461 is fixedly installed on the first mounting plate 412. The bottom piston end of the second electric cylinder 461 is connected to the short column 462. The short column 462 is used to be inserted into any one of the several positioning ports 211 for fixing.

[0043] As one implementation method, such as Figure 10 As shown, the sliding and fixing mechanism 3 includes a fixing plate 31, a slide rail 32, a sliding table 33, and an L-shaped fixing member 34. The slide rail 32 is mounted on the base frame 1 through the fixing plate 31. The sliding table 33 is slidably connected to the slide rail 32 and is used to support the frame 2. The L-shaped fixing member 34 is fixedly disposed on one side of the sliding table 33 and is used to fix the frame 2 at the upper limit of the fixing plate 31. Several positioning holes 311 for matching the L-shaped fixing member 34 are arranged on the fixing plate 31.

[0044] As one implementation method, the push rod 42 is a hexagonal rod structure (25mm across sides) and made of 40Cr material (melting point 1500℃). Combined with the automatic adjustment mechanism for the height difference of the rod head, it can adapt to the ±1° tilt of the air hole and avoid misalignment between the push rod and the hole.

[0045] The working principle of this utility model is as follows: First, by adjusting the sliding fixing mechanism 3 and the elastic limiting component 44, the push rod 42 is aligned with the air hole of the side-blown furnace. Then, the translation mechanism 41 drives the push rod 42 to quickly extend and retract on the elastic limiting component 44 (thrust force approximately 4290N, speed range: 0-1700mm / s, stroke 1400mm) to move the air hole. Specifically, the drive end of the motor 411 (2000r / min) is equipped with a gear adapted to the rack 414, thereby meshing and driving the first... Mounting plate 412 and second mounting plate 413 are provided. The push-pull assembly 45 on the first mounting plate 412 is engaged with the auxiliary adjustment assembly 43 on the second mounting plate 413. The ball joint groove 4331 on the right side of the auxiliary adjustment assembly 43 is used to connect one end of the push rod 42. The other end of the push rod 42 passes through the through hole 4491 on the positioning block 449. The left and right sides of the positioning block 449 are connected to the support frame 448 through the second spring rod 4482. The top and bottom of the support frame 448 are connected through the first spring rod 4482. 481 is connected to the first adjusting plate 443 and the second adjusting plate 444 respectively. When the handwheel 446 is turned manually, the distance between the first adjusting plate 443 and the second adjusting plate 444 can be adjusted, thereby allowing the positioning block 449 with the push rod 42 inserted to be adjusted at a small angle. This allows it to be used when there is a certain height difference between the push rod 42 and the air vent. When the push rod 42 encounters resistance during extension and retraction, the thrust reaches the set value, and the motor 411, in conjunction with the rack and pinion 414, drives the air to blow away from the side. One side of the furnace tuyere hole is retracted to the corresponding positioning port 211. The piston end of the second electric cylinder 461 extends and inserts the short column 462 into the positioning port 211, so that the first mounting plate 412 is relatively fixed on the guide rail 416. The first electric cylinder 451 is started to push and pull slowly (the first electric cylinder 451 is an explosion-proof electric cylinder with a thrust of 20400N, a speed range of 0-80mm / s, and a stroke of 200mm). The auxiliary adjustment component 43 and the push rod 42 connected in the ball head groove 4331 are then used to complete the action of opening the tuyere.

[0046] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
