A control motor 22 is arranged on the hoisting platform 21.

[0030] The control mechanism includes a first motor 33, a first lead screw 34 and a first guide rod 35 disposed inside the hoisting control cylinder 26. The first motor 33 is used to drive the first lead screw 34. A sliding seat 36 is movably disposed on the first lead screw 34 and the first guide rod 35.

The fixing plate 15 is pushed by the base 37, and the push rod 18 is pushed by the deflection push wheel 43.

[0031] Operation principle: The installation and fixation of the logging-while-drilling tool assembly 2 are achieved by the cooperation of the fixing seat 3 and the card slot inside the drill pipe 1. The limiting part 12 at one end of the limiting push seat 10 limits the push wheel 9 to restrict the movement of the push frame 7. When performing the fishing operation, first release the fixed state between the drill pipes 1 of the logging-while-drilling tool assembly 2. Specifically, the hoisting control cylinder 26 is located in the second installation cylinder 14 in a hoisting form, and the hoisting control cylinder 26 is supported by the support rolling plate 20. By controlling the operation of the motor 22, the gear ring 24 rotates, so that the centering rod 27 rotates. The centering rod 27 contacts the inner wall of the second installation cylinder 14, so that the hoisting control cylinder 26 performs concentric adjustment in the second installation cylinder 14, that is, the axis of the hoisting control cylinder 26 coincides with the logging-while-drilling tool assembly 2. By the operation of the azimuth motor 25, that is, controlling the rotation of the hoisting control cylinder 26 for angle adjustment, the deflection motor 30 drives the fixed electric cylinder 29 to deflect. The fixed electric cylinder 29 deflects to the outside of the hoisting control cylinder 26. The deflection motor 30 controls the movement of the fixed shaft 31. The displacement detection rod 32 contacts the inside of the second installation cylinder 14. When the displacement detection rod 32 corresponds to the fixed hole inside the second installation cylinder 14, the displacement detection rod 32 is inserted into the fixed hole. The position sensor outputs and feeds back the displacement signal of the displacement detection rod 32, that is, judges the fixed angle. By controlling the cooperation of the fixed shaft 31 and the fixed hole, the fixation of the second installation cylinder 14 is achieved. Then the subsequent hoisting can be carried out.

[0032] Further, by controlling the electric cylinder 19, the support roller plate 20 is controlled to move outward. The first motor 33 operates, and the first lead screw 34 rotates, causing the sliding seat 36 to move and be located inside the first mounting cylinder 13. The base 37 pushes the fixed plate 15, causing the clamping shaft 16 on the fixed plate 15 to disengage from one end of the limit push seat 10. Then, by pushing the electric cylinder 39 to operate, the push table 40 moves. Under the connection action of the connecting rod 42, the deflection push rod 41 deflects, and the deflection push wheel 43 pushes the push rod 18, causing the limit push seat 10 to move. The limiting portion 12 moves and releases the limit on the push wheel 9. The inclined surface area on the limit push seat 10 pushes the push wheel 9, causing the push frame 7 to move. The extrusion wheel 6 moves in the inclined groove 4 to push the fixed seat 3, and the fixed seat 3 retracts inward to release the fixed state with the drill pipe 1. By limiting the push wheel 9 with the limiting portion 12 and fixing the limit push seat 10 with the clamping shaft 16, two-stage limit fixation is achieved, ensuring the stable fixed state of the fixed seat 3 and the inner card slot of the drill pipe 1.
