10. An automatic centering method for a tripping pipe, at least comprising the automatic centering platform for the tripping pipe of any one of claims 1-9, characterized by further comprising the following steps:
the first step is as follows: the first oil pipe is hoisted by a crane, the mechanical arm (6) drives the mechanical arm (61) to grab the bottom end of the first oil pipe, the mechanical arm (6) moves to drive the mechanical arm (61) to support the first oil pipe to be aligned with the wellhead (1) to lower the first oil pipe, the first oil pipe enters the pneumatic slip (4), the mechanical arm (61) is loosened, the mechanical arm resets, the first oil pipe is lowered, the first oil pipe penetrates through the pneumatic slip (4) and the self-sealing blowout preventer (5) to enter the wellhead (1), and when the joint hoop part of the first oil pipe is positioned in the pneumatic slip (4), the pneumatic slip (4) is started to lock the first oil pipe;
the second step is that: oil is injected through the oil inlet (54), the oil bag (52) is bulged, and the first oil pipe is pushed to approach to the center, so that the centering of the first oil pipe is completed;
the third step: the second oil pipe is hoisted by a crane in a whole, and the second oil pipe and the first oil pipe are supported by a mechanical arm (61) driven by a mechanical arm (6) to be positioned on the same axis;
the fourth step: starting the motor (90), driving the end of the motor (90) to drive the gear (92) to rotate, because the gear (92) is meshed with the rack (91), the portal frame (8) slides on the guide rail (89) and is close to the well head (1), the pair of semi-annular surrounding columns (84) are buckled outside the second oil pipe under the support of the scissor frame (87), the front and back positions of the portal frame (8) are adjusted to ensure that the second oil pipe and the first oil pipe are completely positioned on the same axis, then the force of clamping the second oil pipe by the semi-annular embracing column (84) is slightly loosened to enable the second oil pipe to fall onto the joint hoop of the first oil pipe, and then completely loosening the second oil pipe by the semi-annular embracing column (84), continuously enabling the door-shaped frame (8) to be close to the oil pipe, clamping the oil pipe by the oil pipe hydraulic clamp (82), and enabling the first oil pipe and the second oil pipe to be positioned on the same axis to finish centering, namely enabling the first oil pipe and the second oil pipe to be buckled by the oil pipe hydraulic clamp (82).
