[0044] Please see Figures 1 to 13 In some embodiments of the present invention, the main structure employs a matrix-style storage method for drill rods, with multiple horizontal columns and vertical layers. To further increase the capacity of the drill rod boxes, two drill rod boxes are arranged in the same plane and placed adjacent to each other on the drilling rig platform. During the relocation of the drilling rig, all drill rods can be loaded into the drill rod boxes and transported to the construction site together with the drilling rig.

[0045] The matrix drill pipe conveying system consists of a matrix drill pipe storage system, a translation component 2, a drill pipe gripping system 3, drill pipes 4, and a drill pipe transfer device 5. The main functions and structural features of each component are as follows.

[0046] The matrix-type drill pipe storage system includes drill pipe storage units 1 arranged in a matrix for the fixed placement and storage of drill pipes. The top of each drill pipe storage unit 1 is an open structure, and the side panels 104 are evenly spaced with drill pipe holding slots via partitions. The base 102 is bolted to the drilling platform. To facilitate manual replenishment or retrieval of drill pipes, the side panels 104 are equipped with a flip-up movable baffle 101. The baffle 101 has a pin seat at the top and an ear plate at the bottom, connected to the pin seats on the base 102 and side panels 104 via connecting pins. A slide rail 103 is provided along the length of the drill pipe on the outside of the drill pipe housing for the translational movement of the drill pipe gripping system 3.

[0047] The translation component 2 is a drive device for moving the drill pipe gripping system 3 along the slide rail 103 outside the matrix drill pipe storage system. This embodiment uses a two-stage traveling cylinder as an example. The cylinder barrel of the first traveling cylinder 205 is fixedly connected to the matrix drill pipe storage system via a cylinder mounting base 204. The piston rod of the first traveling cylinder 205 is fixedly connected to the end cover plate of the clamping plate 202. When the piston rod of the first traveling cylinder 205 extends, it can push the clamping plate 202 to move. Slider blocks 201 are provided on the upper and lower sides of the clamping plate 202. The cylinder barrel of the second traveling cylinder 203 is fixedly installed on the clamping plate 202, and the piston rod of the second traveling cylinder 203 is fixedly connected to the drill pipe gripping system 3.

[0048] The drill pipe gripping system 3 is used to transport drill pipes from the matrix drill pipe storage system to the designated drill pipe transfer device 5. The drill pipe gripping system 3 consists of a gripper assembly 301, a telescopic cylinder, a crossbeam, and other components. The main functions and features of each component include:

[0049] (1) First telescopic cylinder 304

[0050] The first telescopic cylinder 304 is externally equipped with a cylinder lug 3042 for connecting other related components; it is equipped with a slider 3041, which can move along the external slide rail of the drill pipe box. The first outer cylinder 3046 is fixedly connected to the slider 3041. The first inner cylinder 3045, which is fixedly connected to the crossbeam assembly 303, is located inside the first outer cylinder 3046 and can move up and down along the first outer cylinder 3046; the first telescopic cylinder 3044 is fixedly connected to the lower end cover of the first outer cylinder 3046, and the piston rod of the first telescopic cylinder 3044 is fixedly connected to the crossbeam assembly 303 through the first pin 3043. When the piston rod of the first telescopic cylinder 3044 is in action, it drives the first inner cylinder 3045 and the crossbeam assembly 303 to move up and down.

[0051] (2) Translation component

[0052] For driving the gripper assembly 301 to move along the crossbeam assembly 303, the preferred method in this application is for the motor to drive the translational gear to mesh with the rack 3031. The motor is fixedly mounted on the motor mounting base 3022 of the second telescopic cylinder 302, and the rack 3031 is fixedly connected to the crossbeam assembly 303 by bolts.

[0053] (3) Second telescopic cylinder 302

[0054] The gripper assembly 301 and the second telescopic cylinder 302 can move along the length of the crossbeam assembly 303. In this application, the preferred method is to drive the translation gear to mesh with the rack 3031 via a motor. Therefore, the figure shows a motor mounting base 3022 and a track base 3025, both of which are fixedly connected to the second outer cylinder 3023 by welding. The track base 3025 can move along the slide rail in the crossbeam assembly 303. The upper end cover of the second outer cylinder 3023 is fixedly connected to the cylinder of the second telescopic cylinder 3021. The piston rod is fixedly connected to the gripper assembly 301 via a pin 3013. The lower part of the second inner cylinder 3024 is fixedly connected to the gripper assembly 301 via bolts. When the second telescopic cylinder 3021 drives the gripper assembly 301 to move downward, the second inner cylinder 3024 also moves downward at the same time.

[0055] (4) Gripper assembly 301

[0056] The connector 3014 is used for the fixed installation of parts such as the hydraulic cylinder 3012 and the gripper 3011, and also for connecting the gripper assembly 301 to the second telescopic cylinder 302 or other related components. The cylinder barrel of the clamping hydraulic cylinder 3012 is fixedly connected to the connector 3014 by a pin. The piston rod of the hydraulic cylinder 3012 is connected to the hydraulic cylinder connection hole of the first gripper 30112 by a third pin 30121. The second gripper 30111 and the first gripper 30112 are respectively provided with fixing pin connection holes, and are fixedly connected to the connector 3014 by the gripper fixing pin 30113. Both the first gripper 30112 and the second gripper 30111 are provided with connection holes for the installation of the transmission rod pin 30122. The lower half of the first gripper 30112 and the second gripper 30111 is a clamping section with both inner and outer surfaces mainly composed of arcs. The inner arc of the clamping section matches the outer surface of the drill rod.

[0057] 2. Process of grabbing the drill rod

[0058] The drill rod box 1 is fixedly connected to the drill rig body via the base plate 102. The movable baffle 101 is opened, and drill rods are loaded into the drill rod box 1. After the drill rods are loaded, the movable baffle 101 is connected to the side wall 104 with a pin. Under the action of the translation component 2, the drill rod gripping system 3 moves along the drill rod axial direction via the slide rail 103 of the drill rod box 1 to grip the drill rods in the left and right drill rod boxes. The gripper component 301 can move along the crossbeam component 303 to grip the drill rods between each row. The translation component 2 can increase the translation distance of the drill rod gripping system 3 via two-stage travel cylinders.

[0059] When the drill pipe gripping system 3 needs to grip the drill pipe in the right drill pipe box, the first travel cylinder 205 and the second travel cylinder 203 retract completely. At this time, the drill pipe gripping system 3 is positioned in the middle of the right drill pipe box. By controlling the cylinder inside the telescopic outer cylinder of the drill pipe gripping system, the gripper assembly 301 is driven to move up and down to grip drill pipes of different layers. The gripper assembly 301 and the second telescopic cylinder 302 can move along the crossbeam slide rail. In this application, a motor-driven gear and rack meshing method is used to grip drill pipes in different rows. When the gripper assembly 301 is fully released, the clamping cylinder 3012 extends completely. When it is necessary to clamp the drill pipe, the cylinder retracts, and the piston rod drives... The first gripper 30112 rotates around the fixed pin 30113, and its gripper holding section swings inward and retracts. The first gripper 30112 transmits the swing to the second gripper 30111 through the transmission rod 30123, driving the left gripper holding section to swing inward and retract, so that the left and right grippers retract inward at the same time to clamp the drill rod. After the hand gripper assembly 301 moves to place the drill rod into the drill rod slot 504 of the transfer device, the clamping cylinder 3012 extends and the hand gripper assembly 301 releases the drill rod. Under the action of the clamping cylinder 502, the transfer device adjusts the position of the drill rod from both sides to the middle and clamps the drill rod at the same time. When other mechanisms grab the drill rod onto the frame holder, the addition of the drill rod is completed.

[0060] When the gripper assembly 301 needs to grab the drill rod in the drill rod box on the left, the first travel cylinder 205 extends fully, and the second travel cylinder 203 controls the stroke of the piston rod to reach the optimal position for the gripper assembly 301 to grab the drill rod.

[0061] 2. Drill pipe return process

[0062] When returning the drill pipe, other mechanisms send the drill pipe back to the drill pipe transfer device. The clamping cylinder 502 of the transfer device extends, increasing the axial space for placing the drill pipe and increasing the fault tolerance. Before the gripper assembly 301 moves to the drill pipe transfer device to grab the drill pipe, the cylinder 502 clamps once and then releases, which is used to calibrate the relative position of the drill pipe and the drill pipe box. Subsequently, the gripper assembly 301 grabs the drill pipe under the action of the clamping cylinder 3012. The gripper assembly 301 moves along the crossbeam assembly 303, selects the empty drill pipe position in the drill pipe box through the electronic control program, and accurately positions it through the travel cylinder to put the drill pipe back into the drill pipe box.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
