The carrying trolley 1 described in this embodiment can realize the lifting and tilting of the trolley carrying platform by two independently controlled lifting cylinders 8. The carrying trolley 1 comprises two liftable stoppers 6 controlled by an oil cylinder 5 and used for preventing the drill rod from sliding down.

The working principle of the automatic drill rod management system in the embodiment is as follows:

(1) when the drill rod is conveyed:

the carrying trolley 1 moves to one side of the drill rod box 2, one end, close to the drill rod box 2, of the platform 4 of the carrying trolley 1 is lowered to be flush with a discharge hole of the drill rod box by controlling the first lifting oil cylinder 8 close to one side of the drill rod box 2, and one end, far away from the drill rod box 2, of the carrying trolley 1 is lowered to be lower than the discharge plane of the drill rod box by controlling the first lifting oil cylinder 8 at the other end; the carrying trolley 1 is in an inclined state, and the stop block 6 is lifted at the lower side; then an inverted lifting oil cylinder 13 in the drill rod box 2 is lifted to drive a liftable drill rod collecting platform 12 to be lifted for a certain height, so that a top layer drill rod and a drill rod pushing device 14 are positioned on the same plane, an oil cylinder of the drill rod pushing device 14 extends out to enable an L-shaped pushing arm 15 with a guide wheel 16 to push out the drill rod, and the drill rod rolls into the carrying trolley 1 along the same line; then, a stop block 6 is lifted at one end, close to the drill rod box, of the carrying trolley 1, the carrying trolley 1 is integrally lifted to the highest position, and the drill rods are conveyed to the position above the pipe support of the power catwalk along the track 10; finally the carriage 2 is lowered to the lowest point and the stop 6 is retracted and moved away from the pipe support along the rail 10, at which time the drill rod remains on the pipe support due to the fact that the carriage is lower in height than the pipe support.

(2) When the drill rod is collected:

when the pipe support of the power catwalk is stored with enough drill rods to fill one layer of the drill rod box 2, the height of the carrying trolley 1 is reduced to the lowest level, the stop block 6 is retracted, the stop block 6 is moved to the lower part of the pipe support, and then the stop block 6 is lifted. Then the carrying trolley 1 is integrally lifted and lifts the drill rod to the maximum stroke, and the height of the carrying trolley is gradually higher than that of the pipe support in the process, so that the drill rod on the pipe support can be jacked up, and the carrying trolley 1 moves towards the drill rod box 2 under the driving of the walking motor 9 to move the drill rod out of the pipe support. Meanwhile, the liftable drill rod collecting platform 12 of the drill rod box 2 is lifted, so that the loading plane is higher than the outer frame 11 of the drill rod box 2; when the carrying trolley 1 moves to the positioning device 3, the carrying trolley integrally descends to the same horizontal plane of the drill rod box; the pushing device 17 of the positioning device 3 extends out to push the uneven drill rods to the limiting device 18 until one end of each drill rod abuts against the limiting device 18, the drill rods finish the alignment step, and the pushing device 17 returns to the original position; then the stop block 6 at one side of the carrying trolley 1 close to the drill rod box 2 falls down, and the first lifting oil cylinder 8 of the carrying trolley at one end far away from the drill rod box 2 rises to incline the carrying trolley 1, so that the drill rod rolls into the drill rod box by matching with the 2-degree inclined design existing on the structure of the drill rod box 2; and finally, the drill rod box falls down to finish the collection of the drill rods.

By using the automatic drill rod management system, 10 drill rods can be taken out and put in at one time, and the loading efficiency is greatly improved.
