A fixing frame is fixedly connected to the top of the column, and the fixing frame is rotatably connected to the middle part of the rocker arm. A high-position fixing hole and a low-position fixing hole are arranged at the inner end of the fixing frame. One end of the rocker arm where the transition block is located is detachably connected to the high-position fixing hole or the low-position fixing hole. When one end of the rocker arm where the transition block is located is connected to the low-position fixing hole, a limiting angle can be formed.
[0007] Furthermore, the middle part of the pin is rotatably connected to the swing rod, and a limit head is provided at the bottom of the pin. When the pin rotates in one direction until one end thereof contacts the limit head, the limit head prevents the pin from continuing to rotate in that direction.
[0008] Furthermore, the two ends of the pin are respectively a stop end and a push end, the center of gravity of the pin is located at the stop end of the pin, and the stop end of the pin rotates under the action of gravity to contact the limit head.
[0009] Furthermore, the transition block is rotatably connected to the swing rod. When the transition block rotates to contact the top end of the fixing frame, the fixing frame provides support for the transition block to limit the transition block.
[0010] Furthermore, the end of the rod storage mechanism close to the column is the near rod end, and the end of the rod storage mechanism away from the column is the far rod end. The far rod end of the rod storage mechanism has a higher vertical height than the near rod end.

At this time, when the worker lifts the partition rod on the rod storage mechanism onto the swing rod, the partition rod is automatically rolled to the one end of the swing rod where the transition block is located under the influence of gravity, and is blocked by the transition block and the fixing frame. Then the driving device drives the column to move close to the end of the drill rod box. At this time, the column is located outside the drill rod box, and the partition rod is located above the drill rod box. The drill rod box rises under the drive of the lifting mechanism. The uppermost drill rod in the drill rod box first contacts the partition rod and lifts the partition rod, so that the partition rod continues to rise and is separated from the swing rod. Then the driving device drives the column to reset. The placement process of the partition rod of the drill rod on this layer is completed.

DETAILED DESCRIPTION
[0018] In order to make the technical means, technical features, invention objectives and technical effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific illustrations.
[0019] Embodiment 1: like Figure 1 and Figure 2 As shown, the present embodiment provides an automatic picking device for a drill rod box of a petroleum drilling rig, comprising a frame 1, wherein the frame 1 is provided with a drill rod box 2 for placing drill rods, the frame 1 is provided with a lifting mechanism 3 which can drive the drill rod box 2 to rise and fall, rod storage mechanisms 4 are provided at both ends of the drill rod box 2, a group of columns 5 are provided between the rod storage mechanism 4 at each end of the drill rod box 2 and the drill rod box 2, each group of columns 5 are located on both sides of the drill rod box 2, a swing rod 6 is provided on the top of the column 5, a thrust pin 7 is provided on the end of the swing rod 6 close to the rod storage mechanism 4, a transition block 8 is provided on the end of the swing rod 6 close to the drill rod box 2, the frame 1 is provided with a driving device, the driving device drives the column 5 to reciprocate between the drill rod box 2 and the rod storage mechanism 4, the lifting mechanism 3 can be a motor cooperating with a lead screw to achieve lifting, or it can be a hydraulic telescopic rod to achieve lifting, this structure is a prior art, and those skilled in the art can select a suitable lifting mechanism 3 for lifting the drill rod box 2 according to actual conditions, which will not be described in detail herein.
[0020] The top of the column 5 is screwed connected to a fixing frame 10, and the fixing frame 10 is rotatably connected to the middle pin shaft of the rocker arm 6. The inner end of the fixing frame 10 is provided with a high-position fixing hole 11 and a low-position fixing hole 12. One end of the rocker arm 6 where the transition block 8 is located is screwed to the high-position fixing hole 11 or the low-position fixing hole 12. When the rocker arm 6 is screwed to the high-position fixing hole 11, the rocker arm 6 tilts toward the end where the thrust pin 7 is located. When the rocker arm 6 is screwed to the low-position fixing hole 12, the rocker arm 6 tilts toward the end where the transition block 8 is located. When one end of the rocker arm 6 where the transition block 8 is located is connected to the low-position fixing hole 12, a limiting angle can be formed.
[0021] When using, when it is necessary to place a barrier rod on the drill rod, one end of the swing rod 6 where the transition block 8 is located is connected to the low-position fixing hole 12. At this time, the swing rod 6 is inclined toward the end of the swing rod 6 where the transition block 8 is located. At this time, when the worker lifts the barrier rod on the rod storage mechanism 4 onto the swing rod 6, the barrier rod automatically rolls to one end of the swing rod 6 where the transition block 8 is located under the influence of gravity, and is fixed within the limit angle surrounded by the transition block and the fixing frame 10. Then the driving device drives the column 5 to move close to the end of the drill rod box 2. At this time, the column 5 is located outside the drill rod box 2, and the barrier rod is located above the drill rod box 2. The drill rod box 2 rises under the drive of the lifting mechanism 3. The uppermost drill rod in the drill rod box 2 first contacts the barrier rod and lifts the barrier rod, so that the barrier rod continues to rise and is separated from the swing rod 6. Then the driving device drives the column 5 to reset, and the placement process of the barrier rod of this layer of drill rod is completed. The above process can be repeated to complete the placement of all barrier rods.
[0022] When it is necessary to remove the interlayer rod from the drill rod, one end of the rocker rod 6 where the transition block 8 is located is connected to the high-position fixing hole 11. At this time, the rocker rod 6 is inclined toward one end of the rocker rod 6 where the thrust pin 7 is located. The lifting mechanism 3 first raises the drill rod box 2, and the column 5 is driven by the driving device to move to the outside of the drill rod box 2. The drill rod box 2 descends, and the interlayer rod descends accordingly and contacts the transition block 8, and falls back onto the rocker rod 6 under the guidance of the transition block 8. The thrust pin 7 can stop the interlayer rod from continuing to roll and prevent it from rolling out of the rocker rod 6. The drill rod box 2 continues to descend, and the interlayer rod is separated from the drill rod. The driving device drives the column 5 away from the drill rod box 2, and then the worker lifts the partition rod from the rocker rod 6 and places it on the rod storage mechanism 4. The above process is repeated to complete the process of removing all the partition rods. The technical solution still requires workers to lift the partition rods, but does not require workers to move the partition rods to the drill rod box 2 and remove the partition rods from the drill rod box 2. The movement of the column 5 replaces the movement of the workers. Therefore, the process of placing and removing the partition rods avoids the workers passing through the rolling path of the drill rods, which not only improves the efficiency of the arrangement of the partition rods, but also reduces safety hazards.
[0023] Embodiment 2: The similarities between this embodiment and the first embodiment are not repeated here, and the differences are as follows: Preferably, the middle part of the thrust pin 7 is rotatably connected to the pin shaft of the swing rod 6, and the bottom screw of the thrust pin 7 is fixedly connected to the limit head 13. When the thrust pin 7 rotates in one direction until one end thereof contacts the limit head 13, the limit head 13 prevents the thrust pin 7 from continuing to rotate in the direction. Preferably, the two ends of the thrust pin 7 are respectively the stop end 14 and the push end 15. The center of gravity of the thrust pin 7 is located at the stop end 14 of the thrust pin 7. The stop end 14 of the thrust pin 7 rotates to contact the limit head 13 due to gravity. When the interlayer rod is removed from the drill rod box 2, the interlayer rod rolls on the inclined swing rod 6 to the stop end. At the push pin 7, since the push pin 7 can rotate and is affected by gravity, its pushing end 15 is located above the rocker arm 6, and its stopping end 14 is located below the rocker arm 6 and contacts the limit head 13. At this time, the push pin 7 cannot play a limiting role, so the partition rod will run over the pushing end 15 of the push pin 7, and the push pin 7 will rotate to be flush with the rocker arm 6 due to the pressure of the partition rod, so that the partition rod passes through. After the partition rod passes through, it is affected by gravity, and the stop end 14 of the push pin 7 falls to the bottom of the rocker arm 6 and contacts the limit head 13, and the pushing end 15 rotates to the top of the rocker arm 6 again.
[0024] Preferably, the transition block 8 is rotatably connected to the rocker arm 6 by a pin. When the transition block 8 rotates to contact the top of the fixing frame 10, the fixing frame 10 provides support for the transition block 8 to limit the transition block 8, so that the transition block 8 will not rotate when the interlayer rod on the guide drill pipe falls onto the rocker arm 6.
[0025] Preferably, the end of the rod storage mechanism 4 close to the column 5 is the near rod end, and the end of the rod storage mechanism 4 away from the column 5 is the far rod end. The far rod end of the rod storage mechanism 4 has a vertical height higher than its near rod end. The top of the rod storage mechanism 4 is recessed toward its bottom to form a limiting groove 16. The limiting groove 16 is located at the near rod end of the rod storage mechanism 4. This structure ensures that the partition rod placed on the rod storage mechanism 4 is always close to its near rod end under the influence of gravity, which is convenient for taking and storing the partition rod. The limiting groove 16 can limit the partition rod to prevent the partition rod from rolling off the rod storage mechanism 4 due to gravity.
[0026] Preferably, a sliding groove 17 is provided on the side wall of the rod storage mechanism 4, a push rod 18 is provided in the sliding groove 17, a flip block 19 is provided on the top of the push rod 18, the rod storage mechanism 4 and the flip block 19 are rotatably connected through a pin shaft, and when the push rod 18 slides in the sliding groove 17, the flip block 19 can be driven to rotate relative to the rod storage mechanism 4, and when the column 5 is close to the rod storage mechanism 4 and the interlayer rod is taken from the rod storage mechanism 4, the outer end of the fixed frame 10 contacts the push rod 18 and pushes the push rod 18 to slide in the sliding groove 17, and when the fixed frame 10 contacts the push rod 18, the push rod 18 is pushed to slide to the right, and the flip block 19 When the interlayer rod is stored in the rod storage mechanism 4, the push rod 18 is first moved to the rightmost end of the sliding groove 17 so that the push rod 18 does not contact the flip block 19, and when the fixed frame 10 is close to the rod storage mechanism 4, it will not contact the push rod 18, thereby avoiding the rotation of the flip block 19 when taking the rod from the rod storage mechanism 4 to hinder the rod storage process.
[0027] Preferably, the driving device includes a hydraulic cylinder 9 and a guide rail 20, the guide rail 20 is fixedly connected to the frame 1 by screws, the column 5 is slidably connected to the guide rail 20, and the hydraulic cylinder 9 drives the column 5 to slide relative to the frame 1. Preferably, guide rods 21 are slidably connected to both sides of the column 5, and the guide rods 21 are fixedly connected to the frame 1 by screws. The guide rods 21 and the guide rail 20 of the driving device work together to realize the sliding of the column 5 relative to the frame 1.
[0028] Preferably, the rocker arm 6 is detachably connected to the high-position fixing hole 11 or the low-position fixing hole 12 by screws, a threaded hole is provided at the stop end 14 of the locking thrust pin 7, and the rocker arm 6 is provided with a fixing part 22. When the fixing part 22 is connected to the threaded hole, the locking thrust pin 7 is flush with the rocker arm 6, and the fixing part 22 is a bolt.
[0029] The workflow includes a rod taking mode for taking out the interlayer rods from the drill rod box 2 and a rod placing mode for placing the interlayer rods on the drill rod box 2 .
[0030] The rod retrieval mode is the process of taking out the interlayer rods placed on the drill rod layer and transferring them to the rod storage mechanism 4. First, the position of the column 5 needs to be adjusted: the swing rod 6 is connected and fixed to the high-position fixing hole 11; the transition block 8 is flipped out and placed on the top of the fixed frame 10 by gravity; the fixing piece 22 of the thrust pin 7 is removed, so as to adjust it to a free rotation state, and it will stop at the limit head 13 and tilt due to gravity. Adjust the rod storage mechanism 4: place the push rod 18 on the outside of the flip block 19 to ensure that the flip block 19 will not tilt in the rod retrieval mode.
[0031] Operation process of taking rods from drill rod box 2: like Figure 3 and Figure 6 As shown, operate the lifting mechanism 3 to lift the drill rod box 2 and the drill rod inside to a height where the target interlayer rod is higher than the transition block 8; operate the reversing valve to fill oil into the rodless chamber of the hydraulic cylinder, and the hydraulic cylinder 9 extends to push the column 5 and the mechanism thereon to the side of the drill rod box 2 until the cylinder is fully extended, at which time the transition block 8 will be directly below the target interlayer rod; operate the lifting mechanism 3 to lower the drill rod box 2, and when the target interlayer rod falls to the transition block 8, it will roll downward along the downward inclined path of the transition block 8 and the rocker arm 6 due to gravity; when it hits the raised anti-thrust pin 7, the interlayer rod will smoothly pass over the anti-thrust pin 7 due to its larger mass and kinetic energy and stop at the fixed The thrust pin 7 will be placed on the groove at the end of the frame 10; the thrust pin 7 will also return to the tilted state after the interlayer rod passes over; the reversing valve is operated to fill the rod chamber of the hydraulic cylinder 9 with oil, and the hydraulic cylinder retracts to push the column 5 and the target interlayer rod to the rod storage mechanism 4; because the swing rod 6 is connected to the high-position fixed hole 11, the swing rod 6 is tilted toward the end where the thrust pin 7 is located, and because the thrust pin 7 is limited by the limit head 13, when the column 5 moves and retracts, the thrust pin 7 will push the target interlayer rod on the right side to slide obliquely upward along the top of the rod storage mechanism 4, and at the same time, it can push the other interlayer rods that are already on the top of the rod storage mechanism 4 to slide upward in turn, completing the work of the target interlayer rod entering the rod storage mechanism 4. According to the above procedure, the storage of other interlayer rods is completed.
[0032] Operation process of placing rods on drill rod box 2: Adjust the column 5: connect and fix the swing rod 6 to the low-position fixing hole 12. The swing rod 6 is tilted toward the end where the transition block 8 is located, and the swing rod 6 forms a limit angle with the fixing frame 10; the transition block 8 and the thrust pin 7 are retracted and fixed inside the swing rod 6. Adjust the rod storage mechanism 4: place the push rod 18 inside the flip block 19 or on the left side in the figure, to ensure that the rod removal bracket can push the push rod 18 in the rod release mode, thereby tilting the flip block 19.
[0033] Operation process of release mode: like Figure 4 and Figure 5As shown, the drill rod box 2 is operated to rise, and the drill rod layer is dropped to a height lower than the limit angle formed by the swing rod 6 and the fixed frame 10; the reversing valve is operated to fill oil into the rod chamber of the hydraulic oil cylinder 9, and the hydraulic oil cylinder 9 retracts to push the column 5 toward the rod storage mechanism 4; when the right end of the fixed frame 10 touches the extended push rod 18, it will push the push rod 18 to move toward the side of the rod storage mechanism 4; the push rod 18 will lift the flip block 19, and then lift the interlayer rod located at the top of the flip block 19 in the limit groove 16; since the two flip blocks 19 of the rod storage mechanism 4 are connected by the same rotating shaft, it can ensure that the two ends of the interlayer rod are lifted synchronously; the interlayer rod rolls along the flip block 19 to the fixed frame 10; at the same time, the tilting of the flip block 19 can The other interlayer rods on the rod storage mechanism 4 are isolated to ensure that only one interlayer rod rolls into the picking mechanism; the interlayer rod rolls to the limit angle formed by the swing rod 6 and the fixed frame 10 and stops; the reversing valve is operated to fill the rodless chamber of the hydraulic cylinder 9 with oil, and the hydraulic cylinder 9 extends to transport the interlayer rod to the side of the drill rod box 2; when the fixed frame 10 touches the interlayer rod located between the drill rod layers, it will push it together until the hydraulic cylinder is fully extended; the lifting mechanism 3 is operated to make the drill rod box 2 rise, lift the drill rod layer, and lift the interlayer rod within the limit angle surrounded by the fixed frame 10 and the swing rod 6 together, and it can be stopped when the target interlayer rod is higher than the fixed frame 10; the column 5 is retracted to complete the work of placing the target interlayer rod on the drill rod layer. According to the above procedure, the placement of other interlayer rods is completed. In order to ensure that the stress conditions of the drill rod layer are good, the interlayer rods can be pushed to the same stress surface through the fixed frame 10.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should belong to the technical scope of the present invention.
