The utility model relates to a quick-opening type clamping and locking device for an
oxygen-enriched burner of a metallurgical furnace, which belongs to the field of connecting workpieces and comprises an
upper tooth jaw, a
lower tooth jaw and a locking component. The left sides of the
upper tooth jaw and the
lower tooth jaw are connected through a shaft, and the right sides of the
upper tooth jaw and the
lower tooth jaw are connected through a locking
assembly in an opening and closing manner; the locking
assembly comprises a locking arc plate, a connecting pin A, a locking buckle, a sliding pin, a connecting pin B and two connecting rods. The locking arc plate is provided with a sliding groove, the sliding pin penetrates through the sliding groove to be connected with the locking arc plate in a sliding mode, the connecting pin A is connected with the lower tooth jaw shaft, and the connecting pin B is connected with the upper tooth jaw shaft. The two connecting rods are respectively connected to two ends of the sliding pin and the connecting pin B; the locking buckle is arranged on the inner side face of the locking arc plate. A
rhinoceros angle plate which can be buckled with the locking buckle is arranged at the outer end of the right side of the lower tooth jaw; according to the utility model, the quick clamping of the high-pressure hose and the
oxygen lance can be realized, the
pressure resistance is strong, the clamping is firm, and the risk that the high-pressure hose and the
oxygen lance fall off is greatly reduced or avoided.
