6) the elevator is arranged at the end of the oil pipe coupling hoop, the lifting electric push rod is controlled to contract to drive the arc-shaped oil pipe pillow to move downwards to the lower part of the sliding base, the end of the oil pipe coupling hoop is lifted by the elevator, and in the lifting process, the sliding motor is controlled to drive the sliding trolley to slide along the sliding rail to be close to the wellhead device to assist in lifting the oil pipe;
7) when the oil pipe is lifted to the center line of the well hole, the sliding motor is controlled to stop rotating, then the sliding wrapping motor is controlled to rotate reversely to drive the sliding semicircular wrapping piece to slide into the sliding cavity, then the sliding motor is controlled to rotate forwards continuously to drive the sliding trolley to slide along the sliding rail continuously to deviate from the position right above the wellhead device,
8) controlling a sliding electric push rod to push the hydraulic tubing tongs to the center of the well hole, releasing the hydraulic tubing tongs after the hydraulic tubing tongs are buckled, and then resetting the hydraulic tubing tongs;
9) loosening the pneumatic slip, lowering the tubing string, and clamping the tubing string by using the pneumatic slip again;
the use method of the oil lifting pipe specifically comprises the following steps:
1) lifting a plurality of connected oil pipes to the height of one oil pipe through an elevator, aligning the end of the coupling hoop to the height of the hydraulic oil pipe tongs, controlling the sliding electric push rod to extend, pushing the hydraulic oil pipe tongs to the center of a borehole, operating the hydraulic oil pipe tongs to be unscrewed, and then loosening the hydraulic oil pipe tongs to control the hydraulic oil pipe tongs to return;
2) the oil pipe at the lower end is clamped through a pneumatic slip, the auxiliary hinged semicircular pillow is adjusted to be in a vertically downward state, the sliding motor is controlled to rotate reversely to drive the sliding trolley to slide along the sliding rail until the oil pipe is clamped into the auxiliary hinged semicircular pillow, and the sliding wrapping motor is controlled to rotate forwardly to drive the sliding semicircular wrapping piece to slide out of the sliding cavity to wrap the lower end of the oil pipe;
3) when the elevator is lowered, the sliding motor is controlled to drive the sliding trolley to slide along the sliding rail to be far away from the wellhead device to assist in lowering the oil pipe, and when the oil pipe is lowered to be in a horizontal state, the lifting electric push rod is controlled to extend to drive the arc-shaped oil pipe pillow to move upwards until the arc-shaped oil pipe pillow is in contact with the bottom wall of the oil pipe;
4) loosening the elevator, adjusting the lifting bearing pushing piece and the lowering bearing pushing piece to move downwards to the same height and move downwards to the lower part of the auxiliary hinged semicircular pillow, controlling the pushing electric push rod to extend to drive the inclined push block to move upwards to push the oil pipe on the arc-shaped oil pipe pillow and the auxiliary hinged semicircular pillow to move upwards, and when the pushing electric push rod pushes the inclined push block to move upwards to be higher than the heights of the arc-shaped oil pipe pillow and the auxiliary hinged semicircular pillow, the oil pipe slides downwards to a position between the lifting bearing pushing piece and the lowering bearing pushing piece along the inclined upper wall of the inclined push block;
5) controlling the oil pipe bidirectional conveyor belt to reversely downwards transmit, controlling the lifting electric push rod and the lower discharging push rod to synchronously extend to drive the lifting bearing pushing piece and the lower bearing pushing piece to move upwards to the same height and stop when the lifting electric push rod and the lower discharging push rod move to the same height as the circle center of the driving rotating shaft at the upper end of the lower discharging limiting plate, controlling the lower discharging push rod to extend to drive the lower bearing pushing piece to push the oil pipe to move upwards, when the lower bearing pushing piece moves upwards to be completely higher than the lifting bearing pushing piece, sliding the oil pipe to the oil pipe bidirectional conveyor belt along the oblique bearing plate II, and downwards transmitting the oil pipe to the oil pipe placing frame and sliding.
