When the clamping plate 513 moves to both sides of the outer ring of the drill rod, the motor 2 starts the adjustment disk 37 to rotate. At this time, the plug-in plate 56 on the overlapping groove 38 on the adjustment disk 37 rotates, so that the driven rod 55 rotates, and then drives the bevel gear 1 57 and the bevel gear 2 58 to rotate, so that the driving shaft 59 rotates. Under the joint action of the thread and the guide rod 511, the two sets of side plates 510 move in the direction of approaching each other to clamp and fix the drill rod; the clamped drill rod is transported to the cleaning component 7 in the above manner for the welding ring cleaning operation;

[0068] During the cleaning operation, the driving unit 4 on the stabilizing mechanism 75 is started to move the locking tube toward the two ends of the drill rod. At this time, the locking grooves at both ends of the locking tube come into contact with the two ends of the drill rod, and the drill rod is clamped between the two sets of locking tubes.

[0069] Afterwards, the motor 3 on the driving mechanism 72 is used to drive the screw to rotate, so that the driving power mechanism 74 moves, and the outer ring cleaning mechanism 76 and the inner ring cleaning mechanism 77 connected to the power mechanism 74 move to the inner and outer ring positions of the drill rod;

[0070] At this time, the driving unit three located inside the box body 81 is started, driving the push-pull plate 85 to move, and then the push-pull plate 85 drives the pull rod 1 68 and the pull rod 3 46 to move together, the pull rod 1 68 drives the driven plate 64 to move, and then the adjustment ring 65 moves. At this time, under the action of the pull rod 2 67, the tool mounting plate 1 66 extends from the inner circle of the rotating plate 62, so that the cutting knife on the tool mounting plate 1 66 contacts the outer wall of the drill rod; the pull rod 3 46 drives the retaining plate 47 and the auxiliary rod 43 to move, and under the action of the pull rod 4 45, the tool mounting plate 2 44 extends out of the cleaning head 41, and the cutting knife on the tool mounting plate 2 44 contacts the inner wall of the drill rod;

[0071] When the motor 4 on the driving unit 2 is started, the gear ring 1 83 rotates under the action of the gear 3, and the connecting tube 42 rotates at this time, so that the cleaning head 41 rotates, so that the cutting knife on the cleaning head 41 rotates and starts to perform a rotary cutting operation on the side of the inner ring of the drill pipe; at the same time, the gear ring 1 83 drives the gear 1 84 to rotate, so that the connecting shaft 611 rotates, and then under the action of the gear 2 610 and the gear ring 2 69, the rotating plate 62 rotates, so that the cutting knife on the rotating plate 62 performs a rotary cutting operation on the side of the outer ring of the drill pipe; under the drive of the driving mechanism 72, the outer ring cleaning mechanism 76 and the inner ring cleaning mechanism 77 complete the cleaning operation of the drill pipe welding ring while moving forward;

[0072] By using the scraping mechanism 2 with a spiral structure arranged on the outer ring of the drill rod body 1, when the drill rod is rotating for drilling, the scraper 22 on the main body 21 scrapes the inner wall of the borehole to remove the agglomerated foreign matter adhering to the inner wall of the borehole, so as to avoid the foreign matter blocking the borehole, thereby increasing the resistance of the drill rod and causing it to get stuck. At the same time, the overflow hole 23 is used to filter the drill rod fluid, and the large agglomerated particles are blocked by the baffle plate 24 at the same time, so as to be easily discharged when the drill rod is lifted upward;

[0073] The design first uses a scraping mechanism set on the outer ring of the drill pipe body to remove the agglomerated foreign matter adhering to the inner wall of the borehole, so as to avoid the foreign matter blocking the borehole, thereby increasing the resistance of the drill pipe and causing it to get stuck. At the same time, the overflow hole is used to filter the drill pipe fluid, and large agglomerated particles are blocked by the baffle plate at the same time, so that they can be discharged upward with the drill pipe.

[0074] The drill rod is loaded and unloaded by a rotary table circulation loading and unloading method, which is convenient for rapid loading and unloading of welded drill rods, improves the loading and unloading operation difficulty, and reduces the waiting time for loading and unloading of drill rods;

[0075] The inner weld ring at the welding position of the drill pipe is removed by synchronously cutting and removing the inner and outer rings of the drill pipe, which reduces the inaccurate removal of the inner weld ring caused by the error in the clamping alignment of the drill pipe when the inner and outer edges are not removed synchronously, and improves the efficiency and quality of the inner weld ring removal.

[0076] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
