the utility model provides a blast furnace tapping machine drilling rod central point alignment fixed bolster, includes the cradling piece that two symmetries set up, and the angle is 80 between the cradling piece, and the bottom of cradling piece sets up the nut respectively, connects through fixing bolt between two nuts, and fixing bolt's axis and the contained angle between the cradling piece are 50, and the top of cradling piece sets up the couple.
In order to further realize the utility model, the hook is a cross rod arranged at the top ends of the two support rods, the two cross rods are arranged oppositely, and the cross rod is parallel to the axis of the fixing bolt.
In order to further realize the utility model, the included angle between the cross rod and the support rod is 50 degrees.
In order to further realize the utility model, the axes of the cross rod, the axes of the bracket rod and the axes of the fixing bolts are on the same plane.
In order to further realize the utility model, the nut is a hexagonal nut.
In order to further realize the utility model, the nut adopts an M16 hexagonal nut.
In order to further realize the utility model, the cross rods and the support rods are made of round steel with the diameter of 12 mm.
To further realize the utility model, the support rods are 224mm long and the cross rods are 80mm long.
Utility model compares in prior art's beneficial effect does:
when the baffle of the tapping machine is replaced, the damaged baffle is removed, the drilling rod is hung on the lower edge of a crossbeam of the tapping machine welded 500mm away from the baffle, after a fixing bolt penetrates through a nut and is screwed, one end of the drilling rod is arranged in an included angle between two support rods, the other end of the drilling rod is arranged on the tapping machine and is screwed, at the moment, the center of the drilling rod of the tapping machine is aligned, and a new baffle of the tapping machine can be fixedly welded.
After the utility model is used, potential safety accidents can be effectively eliminated, and the utility model has remarkable social benefit. The baffle re-installation position is accurate, the operation is easy, the baffle replacement can be completed by 2 persons in cooperation, the baffle replacement time is shortened from 4-6 persons in the prior art to 60-70min each time, and the baffle replacement time is shortened to 2 persons in cooperation within 20min, so that the baffle of the new tapping machine can be fixedly and firmly welded. Change the tapping machine baffle at every turn and only need demolish damaged old baffle, fixed tapping machine drill rod center fixed bolster, weld new tapping machine baffle test run once can fix and weld diely, reduced personnel closely observe the risk that equipment test run probably caused mechanical injury accident and burn and scald, reduced operation personnel's intensity of labour to avoided because of the baffle changes the long blast furnace condition of suppressing wind that causes of time, for the blast furnace safety and stability is in the same direction as driving the guarantor navigation.
