[0058] The working principle of this embodiment is as follows: (1) the feeding mechanism 6 transports the drill rod 4 to the reduction drive mechanism 8, and the reduction drive mechanism 8 clamps one end of the drill rod 4: multiple drill rods 4 are stacked in the drill rod packaging box 5, and one of the drill rods 4 in the drill rod packaging box 5 slides on the inclined plate 10. In the initial state, the first baffles 613 at both ends of the fifth connecting shaft 605 are under the action of the third spring 620. The first baffles 613 always contact the frontmost drill rod 4 and prevent the drill rod 4 from sliding out. When the frontmost drill rod 4 needs to slide out, the output end of the fourth electric cylinder 608 drives the wedge block 609 to slide in the horizontal direction, and the wedge block 609 drives the third guide rod 610 to slide along the bottom of the drill rod packaging box 5 Sliding in the horizontal direction, the wedge block 609 conflicts with the fifth connecting shaft 605 during the horizontal movement, the fifth connecting shaft 605 drives the sleeve plate 611 to rotate on the fourth fixed shaft 615, the sleeve plate 611 drives the fifth connecting shaft 605 to descend, the fifth connecting shaft 605 drives the first baffles 613 at both ends to slide downward in the second through holes 617 on the inclined plate 10 respectively, the first baffle 613 is separated from the drill rod 4, and at the same time the sleeve plate 611 drives the fourth connecting shaft 604 to rise, the fourth connecting shaft 604 drives the second baffle 614 to slide upward in the first through holes 616 of the inclined plate 10 respectively, the second baffle 614 moves until it conflicts with the next drill rod 4 and blocks the next drill rod 4 from sliding out.

[0059] The drill rod 4 slides onto the horizontal track 603 of the drill rod packaging box 5, and the output end of the third electric cylinder 607 drives the push plate 601 to slide in the horizontal direction on the second sliding hole 602 of the bottom plate of the drill rod packaging box 5. The second guide rod 606 on the push plate 601 slides in the horizontal direction on the bottom plate of the drill rod packaging box 5. The push plate 601 pushes one end of the drill rod 4 on the horizontal track 603 into the automatic drill rod clamp 801, and the automatic drill rod clamp 801 automatically clamps one end of the drill rod 4.

[0060] (2) The automatic drill rod clamp 801 clamps one end of the drill rod 4 and rotates the other end of the drill rod 4 to the bottom of the lifting mechanism 1. The lifting mechanism 1 clamps the other end of the drill rod 4: the automatic drill rod clamp 801 fixes and clamps one end of the drill rod 4. The output shaft of the second motor 802 drives the sixth gear 807 to rotate through the fifth gear 806, the tenth gear 813, the ninth gear 812, the eighth gear 811, and the seventh gear 810 in sequence. The seventh gear 810 drives the fourth gear 805 to rotate through the seventh connecting shaft 809. The fourth gear 805 drives the third gear 804 to rotate. Since the number of teeth of the sixth gear 807 is equal to that of the third gear 804, the sixth gear 807 is The shape of gear 807 is equal to that of the third gear 804, the sixth gear 807 and the third gear 804 have the same rotation speed, the sixth gear 807 and the third gear 804 drive the sixth connecting shaft 808 to rotate, the sixth connecting shaft 808 drives the automatic drill rod clamp 801 and one end of the drill rod 4 to rotate, the reduction drive mechanism can increase the torque of the sixth connecting shaft 808, the other end of the drill rod 4 moves between the two jaws 108, the two jaws 108 are based on the size of the drill rod 4, each jaw 108 slides on the first connecting shaft 116 respectively, the two jaws 108 clamp the other end of the drill rod 4, and the two jaws 108 are suitable for clamping drill rods 4 of different sizes.

[0061] (3) The automatic drill rod clamp 801 automatically separates from one end of the drill rod 4, and the clamping mechanism 3 clamps the drill rod 4 to straighten it, so that the drill rod 4 is aligned with the entrance just above the well platform 7. When the two clamping jaws 108 stably clamp the other end of the drill rod 4, the automatic drill rod clamp 801 releases from one end of the drill rod 4. During the loosening movement of one end of the drill rod 4, the one end of the drill rod 4 moves to contact the rubber pad 304. The rubber pad 304 is used to buffer the impact of the drill rod 4. At the same time, under the action of the second spring 314, the connecting plate 309 on the rear side of the rubber pad 304 drives the first connecting rod 306 and the second connecting rod 307 to move, which can relieve the impact of the drill rod 4 on the rubber pad 304.

[0062] The output end of the second electric cylinder 303 drives the clamping plate 301 to move in the horizontal direction, and the clamping plate 301 drives the first guide rod 302 to move in the horizontal direction on the side plate of the third support plate 305. The two clamping plates 301 clamp one end of the drill rod 4 to align with the entrance of the well platform 7, and one end of the drill rod 4 is located directly above the entrance end of the well platform 7.

The winch car pulls the gravity hook 107 to move in the vertical direction through the rope 101, and the two claws 108 at the bottom of the gravity hook 107 clamp the other end of the drill pipe 4 to hoist the drill pipe 4 inside the well platform 7.
