[0026] Hydraulic control principle:

[0027] The lifting cylinder 5 of the two guide beams 3 on the left side of the drill rod box is controlled by a one-way and a two-way reversing valve group: the A port of the one-way valve is directly connected to the rod chamber oil port of the left front end lifting cylinder 5, and the B port is connected to the main oil inlet of the synchronous shunt motor 16, and its two oil outlets are respectively connected to the rodless chamber oil ports of the two lifting cylinders 5 on the left side; the A port of the two-way valve is directly connected to the rod chamber oil port of the left rear end lifting cylinder 5, and the B port is blocked; the oil drain port of the synchronous shunt motor 16 is connected to the front end oil return port of the one-way valve 13 to ensure the motor's oil replenishment needs.

[0028] The lifting cylinder 5 of the two guide beams 3 on the right side of the drill rod box is controlled by a three- and four-way reversing valve group: the A port of the three-way valve is directly connected to the rod chamber oil port of the right rear end lifting cylinder 5, and the B port is blocked; the A port of the four-way valve is directly connected to the rod chamber oil port of the right front end lifting cylinder 5, and the B port is connected to the main oil inlet of the synchronous shunt motor 16, and its two oil outlets are respectively connected to the rodless chamber oil ports of the two lifting cylinders 5 on the right side; the oil drain port of the synchronous shunt motor 16 is connected to the front end oil return port of the one-way valve 13 to ensure the motor's oil replenishment needs.

[0030] 1. Pipe out of drill pipe box

[0031] Simultaneously operate the handles of the three-way and four-way reversing valve groups to make the oil from the A ports of the two valve plates flow into the rod chambers of the two lifting cylinders 5 on the right, and the piston rods of the two cylinders retract, thereby pulling the right side of the guide beam 3 up through the wire rope 4, and stop the operation when it is raised to an appropriate height; then, simultaneously operate the handles of the one-way and two-way reversing valve groups to make the oil from the A ports of the two valve plates flow into the rod chambers of the two lifting cylinders 5 on the left, and the piston rods of the two cylinders retract, thereby pulling the left side of the guide beam 3 up through the wire rope 4, and stop the operation when the left and right sides of the guide beam 3 are in a horizontal state; if the front and rear heights of the two lifted guide beams 3 on the left or right side are inconsistent, the lifting cylinder 5 in the corresponding lower position can be operated separately to increase the height of the corresponding guide beam 3 until the front and rear heights of the two guide beams 3 are consistent, and then the two valves are operated simultaneously; in this way, the lifting cylinders 5 on both sides of the drill rod box are operated alternately. When the right side is lifted until the lowest point of the drill rod coupling is higher than the upper plane of the drill rod box body, stop; then continue to operate the two lifting cylinders 5 on the left side to lift the guide beam 3 until the left side of the guide beam 3 is higher than the right side, forming a height difference between the left and right sides, and the entire guide beam 3 is tilted, so that the pipes overcome friction and roll under the action of gravity, and the entire layer of pipes will roll out of the drill rod box along the inclined surface of the guide beam 3, and the pipes will roll into the next drill rod box or catwalk pipe rack through the transition bridge 2, completing the action of the pipes coming out of the box.

[0032] 2. Pipes into the drill rod box

[0033] Simultaneously operate the handles of the one, two, three and four-way reversing valve groups to make the oil outlet from the A port of the four valve plates enter the rod chambers of the four lifting cylinders 5 on both sides to lift the guide beam 3. Stop the operation when the upper plane of the guide beam 3 or the interlayer rod 9 is flush with the upper plane of the drill pipe box body. Operate the handle of the one-way reversing valve group to make the oil outlet from the B port of the valve plate enter the synchronous diversion motor 16, and then enter the rodless chambers of the two lifting cylinders 5 on the left to lower the left side of the guide beam 3 after diversion. Stop when the height difference formed on the left and right sides is sufficient to allow the pipe to roll freely. The pipes on the catwalk pipe rack are within the range of the material hook of the entry arm 6. Operate the handle of the five-way reversing valve group to make the oil flow out of the valve B port and enter the diversion and collecting valve 15. After diversion, the oil enters the rodless chamber of the two flip cylinders 7 to extend the piston rod, and flip the entry arm 6 upward to drive the pipes in the material hook to separate from the pipe rack. When the flip cylinder 7 is fully extended, the entry arm 6 reaches the highest point, and the pipes roll into the drill rod box along the entry arm 6 to complete the action of entering the pipe box; then operate the handle of the five-way reversing valve group to make the oil flow out of the valve A port and enter the rod chamber of the two flip cylinders 7 to retract the piston rod, and then drop the entry arm 6 to prepare for the next drill rod entry work.
