(3) Detection device 4
The detection device 4 is a distance sensor, and the detection device 4 is arranged at the upper part of the rear end plate 103 of the box body 1 and is far away from one end of the drilling machine. Because the diameter of the male head of the drill rod is smaller than that of the female head of the drill rod, the orientation of the drill rod is identified through the different distance induction data of the joints at the two ends of the drill rod by the detection device 4, and therefore the rotating direction of the transposition clamp holder 8 is controlled.

The process of drilling the drill rod comprises the following steps:
(1) the drill rod is placed in the drill rod box in a direction parallel to the rear end plate 103, i.e. the axis of the drill rod is parallel to the arrow marked far and near in fig. 8, without the male and female heads facing each other.
(2) The jacking hydraulic cylinder 201 jacks up the drill rod from the lowest position of the drill rod box, at the moment, more than one drill rod on the jacking frame 202 can be positioned, the upper drill rod slides back into the box body 1 under the action of the wedge-shaped protrusion of the rear end plate 103 of the box body 1, and only the lowest drill rod is left to be the drill rod 3 to be operated.
(3) After the jacking hydraulic cylinder 201 is in the stroke position, the drill rod 3 to be operated is just at the position which can be clamped by the translation clamping mechanism 5. The clamping jaw driving device 503 drives the clamping jaw 504 to clamp the drill rod 3 to be operated. Meanwhile, the distance sensor identifies the orientation of the drill rod through distance sensing data.
(4) The translation drive 502 of the translating and clamping mechanism 5 moves the drill rod in a direction to approach the index gripper 8 (drill) while the index gripper 8 rotates to the position shown in fig. 8 and opens. After the drill rod is translated into position, the indexing gripper 8 grips the drill rod and the jaws 504 release the drill rod and retract.
(5) If the sensor in the step (3) judges that the head is the female head, the transposition clamp 8 rotates forwards according to the figure until the clamping center of the transposition clamp coincides with the horizontal drilling axis of the drilling machine; the male head rotates reversely. I.e. the drill rod is located between the drill head 6 and the drill holder 9.
(6) The drill chuck 7 is released and the drill head 6 is advanced to a position where it can grip the drill rod in the index holder 8 and the drill chuck 7 grips the drill rod.
(7) The indexing holder 8 is released and the drill head 6 is rotated and advanced to complete a threaded connection with the front end drill rod 10 in the drill holder 9.
(8) The drill clamp 9 is loosened, the drill power head 6 is rotated and pushed forward, and drilling is continued.

(1) the drill clamp 9 and the indexing clamp 8 are loosened, and the drill chuck 7 clamps the drill rod to be disassembled.
(2) The drill power head 6 is retracted so that the threaded connection of the drill rod to be removed and the front end drill rod 10 is located between the drill holder 9 and the indexing holder 8.
(3) The drill clamp 9 is clamped, the drill power head 6 is reversely rotated and retreated, and the threaded connection between drill rods is loosened.
(4) The rotating clamp 8 clamps the drill rod, the drill chuck 7 is loosened, the drill power head 6 moves backwards, and the rear end of the drill rod to be disassembled is completely exposed out of the drill chuck 7.
(5) The translation drive 502 of the translating and clamping mechanism 5 drives the jaws 504 to move closer to the index gripper 8 (drill) while the index gripper 8 rotates to the position shown in fig. 8 and remains clamping the drill rod. The jaws 504 are translated into position to grip the drill rod.
(6) The index gripper 8 is released and the translating gripper mechanism 5 drives the drill rod away from the drill rig until it is back directly above the jacking mechanism 2.
(7) The discharging driving device 204 drives the discharging plate 203 to extend, so that the side of the jacking frame 202 close to the rear end plate 103 of the box body 1 is higher. Thus, during the jacking process, the drill rods in the box body 1 cannot stay on the jacking frame 202. The jacking cylinder 201 drives the jacking frame 202 to extend upward to the uppermost position to catch the retrieved drill pipe.
(8) After the jacking frame 202 is in place, the stripper plate 203 is retracted and the jaws 504 release the drill rod.
(9) The jacking hydraulic cylinder 201 drives the jacking frame 202 to retract downwards, and when the bottom is the lowest, the drill rod falls back into the box body 1 along with the jacking rod frame.
The drill rod box and the drill rod conveying device are simple in structure, and the problem of conveying the drill rods is solved by using a plurality of translation mechanisms; the large-capacity loading of the drill rod is realized by a simple box body 1; an open box body 1 structure is adopted, and the middle part is not divided into columns and layers, so that the drill rod is very convenient to take and place; be equipped with the sensor that is used for responding to drilling rod joint, need not to distinguish when getting the putting drilling rod and connect the orientation, improved site operation efficiency.
According to the invention, the jacking mechanism 2 is arranged, so that the automatic taking and placing of the drill rod are realized, the problem that the drill rod positioned at the bottom of the drill rod box is inconvenient to take and place is solved, and the safety of taking and placing the drill rod is improved; by arranging the detection device 4 for identifying the orientation of the drill rod, the problem that the drill rod in the drill rod box must be fixedly oriented to be placed is solved.
By arranging the transposition clamp 8, the flexibility of the additional connection drill rod is improved, and the problem that the drill rod to be additionally connected needs to be placed in parallel with the horizontal drilling axis of the drilling machine is solved; the drill rod feeding device has the advantages that the drill rod feeding route is simplified, the adding and connecting actions are reduced, the adding and connecting efficiency is improved, the action execution precision is guaranteed, and the problems of complex drill rod feeding route, multiple adding and connecting actions and low efficiency are solved.
