Description

Technical Field

[0001] The utility model relates to a centering auxiliary device, in particular to a device which can assist workers in centering a drill rod and facilitate subsequent welding operations, and belongs to the technical field of drill rod equipment of an iron hole opening machine. Background Art

[0002] During the smelting production process of a blast furnace, molten iron is discharged from the iron mouth at the bottom of the blast furnace. The iron mouth needs to be unblocked by an iron mouth opening machine before iron can be tapped. After the drill rod of the iron mouth opening machine drills the iron mouth, the liquid slag in the furnace flows smoothly out of the furnace through the hole drilled by the drill rod to complete the iron and slag tapping work. At present, the drill rods used in most blast furnaces are threaded steel drill rods, that is, the threaded end is connected to the opening machine rock drill. According to the different requirements of the blast furnace for the drill rod, the threaded steel needs to be welded to round steel or hexagonal steel with different diameters. However, under the high-intensity impact and rotation of the rock drill, if the welding of the drill rod is not parallel, the center line of the threaded steel and the drill rod will be offset, resulting in deformation and fracture of the drill rod, and the operation of opening the iron mouth cannot be completed smoothly. Therefore, a centering auxiliary device is needed, which is required to assist the staff to dock the ends of the threaded steel and the drill rod, ensure that they are welded in a state where the center lines coincide, and then ensure that the drill rod can reliably open the iron mouth.
