In order to solve the above problem, the utility model discloses a technical scheme is: the blast furnace tuyere sleeve dismounting device comprises a pull rod, wherein a hook head is arranged at the front end of the pull rod, a backward recoil cushion with a pedal is arranged at the rear end of the pull rod, and a forward recoil cushion is arranged on the side of the pull rod close to the hook head; and a sliding hammer is arranged between the forward recoil pad and the backward recoil pad of the pull rod, and is sleeved on the pull rod and can slide along the pull rod.
In the above technical solution, a more specific technical solution may also be: and a handle is arranged on the sliding hammer.
Furthermore, a rib plate fixedly connected with the pull rod is arranged on one side, close to the sliding hammer, of the retreating recoil pad.
Furthermore, a first reinforcing rib fixedly connected with the pull rod is arranged on one side, close to the hook head, of the forward recoil cushion.
Furthermore, a second reinforcing rib fixedly connected with the backward recoil pad is arranged on the pedal plate.
Further, the tie rod, the forward recoil pad, and the reverse recoil pad are all made of steel.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:
by adopting the utility model to disassemble the tuyere external member of the blast furnace, the whole process only needs 3 to 5 minutes, thereby greatly shortening the disassembly time, improving the disassembly efficiency and reducing the influence of tuyere equipment failure on the production of the blast furnace; the rear end of the pull rod is provided with the pedal plate for being stepped by a worker, so that the hook head is tightly combined with the air port sleeve, the worker can stand conveniently, the worker is not easy to slip and hurt, and potential safety hazards are avoided; the sliding hammer is sleeved on the pull rod to respectively impact the forward recoil pad and the backward recoil pad, and the pull rod and the two sides of the hook head are uniformly stressed, so that the labor intensity is reduced, and the operation in a narrow space such as an air port is facilitated; the forward and backward recoil pads are made of steel materials, and provide impact force, so that the hook head is easy to collide into the air inlet and be collided out of the air outlet.
