[0019] The opening and closing clamping mechanism comprises a connecting shaft 6 connected to the inside of the sleeve 1, two baffles 7 rotationally connected to the connecting shaft 6, a hinged seat 8 connected to the opposite side of each of the two baffles 7, and a flat plate 9 rotationally connected to one end of the hinged seat 8, one end of each of the two flat plates 9 is rotationally connected to the pull rod 10, and one end of each of the two baffles 7 can pass through the two openings 2 and extend to the outside of the sleeve 1. The connecting shaft 6 serves as a rotating fulcrum, cooperates with the lever structure of the hinged seat 8 and the flat plate 9, so that the operator only needs to push and pull the pull rod 10 to drive the baffle 7 to open and close along the opening 2 of the sleeve 1; this transmission mode converts linear motion into rotary motion of the baffle 7, improving the efficiency of operation; the hinged seat 8 and the flat plate 9 are both made of motorcycle chains. The hinged seat 8 and the flat plate 9 are made of motorcycle chains, which have high strength characteristics to ensure that they can withstand a large pulling force when the pull rod 10 is pulled to drive the baffle 7 to abut against the end face of the lance water jacket 20, avoiding component fracture and ensuring smooth disassembly operation.

[0020] The other end of the sleeve 1 is symmetrically provided with two half-external thread rings 3, and the two half-external thread rings 3 are distributed along the axial line of the sleeve 1, the interval of the two half-external thread rings 3 corresponds to the two openings 2 and jointly forms a through opening; the through opening is provided with an embedded head 12 corresponding to one side of the connecting shaft 6, one end of the embedded head 12 is provided with a V-shaped groove 13, and the other end of the embedded head 12 is connected with a threaded connecting block 14; the threaded connecting block 14 is located between the two half-external thread rings 3, and the threaded connecting block 14 is threadedly connected with the two half-external thread rings 3 through the knurled nut 5; the circular side surfaces of the embedded head 12 and the threaded connecting block 14 are respectively matched with the outer walls of the sleeve 1 and the half-external thread rings 3. The symmetrically distributed half-external thread rings 3 jointly form the through opening with the openings 2, and the through opening provides a mounting space for the embedded head 12; the threaded connecting block 14 is detachably connected with the half-external thread rings 3 through the knurled nut 5, so that the threaded connecting block 14 is convenient to disassemble, assemble and adjust.

[0021] Working process and principle: when the lance water jacket 20 is disassembled, first, a positioning nut 18 is screwed on the sleeve 1, then the opening of the fixed plate 15 is aligned with the sleeve 1, and the fixed plate 15 is sleeved on the outer wall of the sleeve 1, and then another positioning nut 18 is screwed to clamp the fixed plate 15, so that the fixed plate 15 is fixed and installed. When operating, the sleeve 1 is inserted into the tuyere of the lance water jacket 20, the operator holds the handle 11 and pushes the pull rod 10 into the sleeve 1, and through the linkage of the pull rod 10, the flat plate 9, the hinged seat 8 and the connecting shaft 6, the two flaps 7 are driven to expand outward through the openings 2; then the pull rod 10 is pulled in the reverse direction, so that the flaps 7 abut against the end face of the lance water jacket 20. Finally, the hydraulic jack 17 is installed in the two fixed cylinders 16 respectively, the two hydraulic jacks 17 generate a pressing force on the side of the furnace wall 19, and through the principle of force interaction, the two hydraulic jacks 17 form a reverse thrust, so that the lance water jacket 20 is disassembled from the furnace wall 19.
