the pipe column enters a drill bit feeding column device: three pipe columns are arranged on a power catwalk inclination mechanism (13), each stop pin (4) is positioned at one end close to the pipe column in a guide groove (1), the inclination mechanism (13) inclines, a first pipe column rolls into the middle of a V-shaped groove, swing cylinders corresponding to all odd-numbered guide grooves (1) drive a guide connecting rod (2), so that the corresponding stop pins (4) positioned at odd-numbered positions slide in the guide grooves (1), the first pipe column is jointly conveyed from one wide side of a frame body (24) to the other wide side and blocks the first pipe column, then the inclination mechanism (13) inclines, a second pipe column rolls into the middle of the V-shaped groove, swing cylinders corresponding to even-numbered guide grooves (1) drive the guide connecting rod (2), so that the corresponding stop pins (4) positioned at even-numbered positions slide in the guide grooves (1) and slide to one side of the second pipe column far away from the first pipe column, and then the inclination mechanism (13) inclines, the third pipe column rolls into a V-shaped groove and is blocked by the stop pins (4) positioned at the even number positions;
conveying the pipe column to a drill floor:
when the drill string feeding device reaches the drill floor (23), the pulley (12) moves forwards to push a second pipe string onto the drill floor, then the pulley (12) returns to the original position, the even-numbered corresponding swing cylinders drive the stop pins (4) to swing towards the odd-numbered stop pins (4), so that a third pipe string rolls into the middle of the V-shaped groove, the pulley (12) moves forwards to push the third pipe string onto the drill floor, then the pulley (12) returns to the original position, then the swing cylinders all act to drive the stop pins (4) to return to the original position, the first pipe string rolls to the middle of the V-shaped groove, the pulley (12) moves forwards to push the first pipe string onto the drill floor, then the pulley (12) returns to the original position, and three pipe strings are fed to the drill floor (23).
