Description

Technical Field

[0001] This invention relates to the field of drilling and production machinery and equipment, and in particular to a drill rod storage mechanism for drilling rigs. Background Technology

[0002] Currently, most drilling rigs rely on manual operation for rod loading. Workers remove the drill rod from the drill rod holder, move it under the drill rig's power head, fine-tune it to align the drill rod's center with the power head's center, and then start the power head's rotation to tighten the drill rod's threads onto the power head's threads. This entire process is manual, labor-intensive, and has a low safety factor. To improve these shortcomings, some existing technologies add automatic rod loading and unloading mechanisms to the drilling rig. However, since the automatic rod loading and unloading actions are entirely automated (either manually operated by a button or controlled by a program), the drill rod must be moved to a fixed position each time to ensure the automatic loading and unloading mechanism can retrieve and place the rod. However, current drilling rigs use ordinary rectangular frame structures for the drill rod holder, making it impossible to arrange the drill rods orderly within the holder. Furthermore, the drill rods inside the holder cannot automatically move to the loading and unloading positions on the drilling rig, affecting the normal operation of automatic rod loading and unloading. Therefore, a drill rod storage mechanism for drilling rigs needs to be developed. Summary of the Invention

[0003] The purpose of this invention is to provide a drill rod storage mechanism for drilling rigs, thereby solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention discloses a drill rod storage mechanism for a drilling rig, comprising a rod storage frame. The bottom front end of the rod storage frame is movably engaged with the frame of the drilling rig. Two rod storage frame lifting cylinders are symmetrically hinged between the bottom rear end of the rod storage frame and the frame of the drilling rig. A lifting arm that can move vertically is provided near the front end of the rod storage frame, and two rod storage lifting cylinders for driving the vertical movement of the lifting arm are symmetrically provided on the rod storage frame. Two drill rod support frames are symmetrically fixed on the lifting arm. Two sets of rod feeders are symmetrically provided at the rear end of the rod storage frame.

[0006] Furthermore, the bottom front end of the rod storage frame cooperates with two rod storage frame hinge seats fixedly mounted on the frame of the drilling rig. The square base of each rod storage frame hinge seat is fixedly connected to the drilling frame. The upper part of each rod storage frame hinge seat is provided with an arc groove. The bottom front end of the rod storage frame is symmetrically provided with two cylindrical support seats that rotatably cooperate with the arc grooves on the two rod storage frame hinge seats.

[0007] Furthermore, the bottom of each of the rod storage frame lifting cylinders is hinged to the pivot cylinder seat fixedly mounted on the frame of the drilling rig, and the telescopic end of each of the rod storage frame lifting cylinders is hinged to both sides of the rear end of the rod storage frame.

[0008] Furthermore, the bottom of each drill rod support frame is fixedly connected to the upper part of the lifting arm, and the upper end of each drill rod support frame is configured as an arc-shaped structure that adapts to the outer periphery of the drill rod.

[0009] Furthermore, the lower ends of the two rod holder lifting cylinders are symmetrically hinged at the bottom center of the rod holder frame; one side of the telescopic end of the two rod holder lifting cylinders is respectively hinged to one end of the first connecting rod and the second connecting rod, the first connecting rod and the second connecting rod have the same shape and their other ends are respectively hinged to the bottom of the rod holder frame; the other side of the telescopic end of the two rod holder lifting cylinders is respectively hinged to two third connecting rods, and the other ends of the two third connecting rods are respectively hinged to the bottom of the lifting arm.

[0010] Furthermore, a first slider and a second slider are symmetrically arranged at both ends of the lifting arm. The first slider and the second slider located at the same end are fixedly connected to form a U-shaped limiting slider. The limiting slider slides in cooperation with the limiting guide rail fixedly arranged on the side of the storage rod frame.

[0011] Furthermore, each of the rod dividers includes a rod support base fixedly mounted on the rod storage frame. A rod support telescopic cylinder is hinged to the bottom center of the rod support base via a cylinder pin. The telescopic end of the rod support telescopic cylinder is connected to one side of a partition plate welded component that is slidably mounted on the rod support base. Two hinge plates are symmetrically fixedly mounted on the rod support base near the other side of the partition plate welded component. The upper ends of the two hinge plates are commonly fixedly connected to a connecting plate fixedly mounted on the upper part of the rod support base. On the opposite sides of the two hinge plates, multiple partition plates are respectively rotatably arranged at intervals by a pin through a partition plate; on the side of each partition plate near the partition plate welded component, a rectangular groove is respectively opened through the partition plate welded component, and the length of the multiple rectangular grooves on the partition plate welded component gradually increases from top to bottom; the upper part of the end of each partition plate away from the partition plate welded component is a planar structure, and the lower part of the end of each partition plate away from the partition plate welded component is provided with multiple arc-shaped limiting grooves that are adapted to the outer peripheral wall of the drill rod.

[0012] Furthermore, multiple partition plates located on the same hinge plate are fixedly provided with anti-rotation welding components between the corresponding hinge plate and partition plate by pins, and each anti-rotation welding component is fixedly provided with a cuboid limiting block below each partition plate to prevent the partition plate from excessively sagging.

[0013] Furthermore, two guide rail pressure plates are symmetrically fixed on both sides of the base of the support frame, and guide rail grooves are formed between the two guide rail pressure plates and the base of the support frame. The two sides of the partition pressure plate welded part are respectively slidably engaged with the two guide rail grooves.

[0014] Furthermore, two tie rods are symmetrically arranged at both ends of the upper part of the rod storage frame, and the two ends of each tie rod are fixedly connected to the rod storage frame by safety pins.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0016] The drill rod storage structure for drilling rigs disclosed in this invention employs hydraulic control. It can rotate the storage frame to achieve outward or inward rolling of the drill rods and to position them. The extension cylinder of the support frame pushes the welded components of the partition plate and pressure plate up and down, causing the partition plate to rotate, enabling layered retrieval and storage of drill rods. By pushing the lifting arm up and down, different layers of drill rods can be fed and stored. Therefore, this invention enables automatic feeding and storage of drill rods, reducing labor intensity during drill rod retrieval and placement, improving work efficiency, and reducing safety risks during operation.

[0043] like Figure 1 As shown, a drill rod storage mechanism for a drilling rig includes a rod storage frame 14. The front bottom of the rod storage frame 14 is movably fitted with the frame of the drilling rig. Two rod storage frame lifting cylinders 1 are symmetrically hinged between the rear bottom of the rod storage frame 14 and the frame of the drilling rig. A vertically movable lifting arm 15 is provided near the front end of the rod storage frame 14, and two rod storage lifting cylinders 2 are symmetrically arranged on the rod storage frame 15 to drive the vertical movement of the lifting arm 15. Two drill rod support frames 16 are symmetrically fixedly installed on the lifting arm 15. Two sets of rod dividers 17 are symmetrically arranged at the rear end of the rod storage frame 14, and rod divider pressure plates 12 are respectively provided at the upper ends of the two sets of rod dividers 17 at the rear end of the rod storage frame 14.

[0044] like Figures 2-4 As shown, the bottom front end of the rod storage frame 14 engages with two rod storage frame hinge seats 19 fixedly mounted on the frame of the drilling rig. The square base 19-1 of each rod storage frame hinge seat 19 is fixedly connected to the drilling frame by welding. The upper part of each rod storage frame hinge seat 19 is provided with an arc groove 19-2. Two cylindrical support seats 14-1 are symmetrically fixedly mounted on the bottom front end of the rod storage frame 14, which respectively rotatably engage with the arc grooves 19-2 on the two rod storage frame hinge seats 19. In addition, a hinge seat pressure block 9 is bolted to the upper part of each rod storage frame hinge seat. The side of the hinge seat pressure block 9 opposite to the rod storage frame hinge seat is also provided with an arc groove, so that the cylindrical support seat 14-1 of the rod storage frame 14 is rotatably mounted between the rod storage frame hinge seat 19 and the hinge seat pressure block 9.

[0045] The bottom of each of the rod storage frame lifting cylinders 1 is hinged to the pivot cylinder seat 3 fixedly mounted on the frame of the drilling rig, and the telescopic end of each of the rod storage frame lifting cylinders 1 is hinged to both sides of the rear end of the rod storage frame 14.

[0046] When the rod splitter 17 is in operation, when the piston rod of the rod storage frame lifting cylinder 1 extends, the rear part of the rod storage frame 14 is higher than the front part, allowing the drill rod to roll forward. When the piston rod of the rod storage frame lifting cylinder 1 retracts, the front part of the rod storage frame 14 is higher than the rear part, allowing the drill rod to roll backward. This structure enables the drill rod to move back and forth within the rod splitter 17.

[0047] like Figures 5-12 As shown:

[0048] The bottom of the drill rod support frame 16 is fixedly connected to the upper part of the lifting arm 15, and the upper end of each drill rod support frame 16 is configured as an arc-shaped structure that adapts to the outer periphery of the drill rod.

[0049] The lower ends of the two rod holder lifting cylinders 2 are symmetrically hinged to the bottom center of the rod holder frame 14. One side of the telescopic end of each of the two rod holder lifting cylinders 2 is hinged to one end of the first connecting rod 6 and the second connecting rod 7 respectively via a first pin 10. The first connecting rod 6 and the second connecting rod 7 have the same shape, and their other ends are respectively hinged to the bottom of the rod holder frame 14. The other side of the telescopic end of each of the two rod holder lifting cylinders 2 is hinged to two third connecting rods 8 respectively via a first pin 10. The other ends of the two third connecting rods 8 are respectively hinged to the bottom of the lifting arm 15 via a second pin 11.

[0050] The lifting arm 15 has a first slider 4 and a second slider 5 symmetrically arranged at both ends. The first slider 4 and the second slider 5 located at the same end are fixedly connected by bolts to form a U-shaped limiting slider. The limiting slider slides in cooperation with the limiting guide rail 14-2 fixedly arranged on the side of the storage rod frame 14.

[0051] When the piston rod of the rod storage cylinder 2 extends, the rotation of the linkage mechanism causes the assembly of the lifting arm 15 and the drill pipe support frame 16 to move upward along the limiting guide rail of the rod storage frame 14 until it reaches the set position (rod take-up / release position). When the piston rod of the rod storage cylinder 2 retracts, the rotation of the linkage mechanism causes the assembly of the lifting arm 15 and the drill pipe support frame 16 to move downward along the limiting guide rail of the rod storage frame 14. Controlled by the hydraulic valve of the cylinder, the drill pipe support frame 16 can be stopped at each layer of drill pipe.

[0052] Then, the piston rod of the rod storage frame lifting cylinder 1 is extended (retracted) so that the front end of the rod storage frame 14 is lower (higher) than the rear end, which allows the drill rod to roll from the rod splitter 17 onto the drill rod support frame 16 (which allows the drill rod to roll from the drill rod support frame 16 onto the rod splitter 17).

[0053] like Figures 13-23 As shown:

[0054] Each of the rod dividers 17 includes a rod support base 17-8 fixedly installed on the rod storage frame 14. A rod support telescopic cylinder 17-1 is hinged to the bottom center of the rod support base 17-8 via a cylinder pin 17-2. The telescopic end of the rod support telescopic cylinder 17-1 is connected to one side of a partition pressure plate welded component 17-10 that is slidably installed on the rod support base 17-8.

[0055] The support frame base 17-8 has two hinge plates 17-6 symmetrically fixedly installed on the other side near the partition plate welded component 17-10. The upper ends of the two hinge plates 17-6 are jointly and fixedly connected to the connecting plate 17-7 fixedly installed on the upper part of the support frame base 17-8. The two small holes at the lower end of the hinge plates 17-6 are positioned and installed with the small holes in the middle welded component of the support frame base 17-8, serving a fixing function. The connecting plate 17-7 is fixedly connected to the small holes at the top of the two hinge plates 17-6.

[0056] The five large holes in the middle of the hinge plate 17-6 are installed in conjunction with the partition plate pin 17-3 and provide support for the partition plate pin 17-3. Multiple partition plates 17-4 are provided on the opposite sides of the two hinge plates 17-6 through the partition plate pin 17-3 at intervals.

[0057] Each of the partition plates 17-4 has a rectangular groove extending through it on the side of the partition plate welding component 17-10 near the partition plate pressure plate welding component 17-10. The length of these rectangular grooves gradually increases from top to bottom. The upper part of the end of each partition plate 17-4 away from the partition plate pressure plate welding component 17-10 is planar, allowing the drill rod to roll on the plane. The lower part of the end of each partition plate 17-4 away from the partition plate pressure plate welding component 17-10 has multiple arc-shaped limiting grooves that fit the outer peripheral wall of the drill rod. These arc-shaped limiting grooves mate with the arc surface of the lower drill rod to prevent the drill rod from rolling back and forth. The circular hole in the center of each partition plate 17-4 engages with a corresponding partition plate pin 17-3, allowing the partition plate 17-4 to rotate around the partition plate pin.

[0058] Multiple partition plates located on the same hinge plate 17-6 are fixedly provided with anti-rotation welded parts 17-9 between the corresponding hinge plate 17-6 and partition plate 17-4 using pins 17-3. Each anti-rotation welded part 17-9 has a cuboid limiting block fixedly provided below each partition plate 17-4. The two round holes of the anti-rotation welded part 17-9 are installed on the corresponding partition plate pins 17-3. The function of the two cuboid limiting blocks welded to the anti-rotation welded part 17-9 is to prevent the partition plate 17-4 from excessively sagging during operation.

[0059] Two guide rail plates 17-5 are symmetrically fixedly installed on both sides of the support frame base 17-8. The two guide rail plates 17-5 form guide rail grooves with the support frame base 17-8. The two sides of the partition plate welded part 17-10 are respectively slidably engaged with the two guide rail grooves.

[0060] The hinge seat of the partition plate pressure plate welded component 17-10 is connected to the bottom of the main body of the support frame telescopic cylinder 17-1. The telescopic end of the support frame telescopic cylinder 17-1 is connected to the bottom hinge seat of the support frame base 17-8 via a pin. The rear ends of the five assembled partition plates 17-4 are respectively snapped into the five rectangular slots of the partition plate pressure plate welded component 17-10. During operation, the movement of the piston rod of the support frame telescopic cylinder 17-1 causes the partition plate pressure plate welded component 17-10 to move up and down, and the upper edge of the rectangular slot causes the partition plate 17-4 to rotate.

[0061] The state of the drill rod after storage in this practical shape is as follows: Figure 24 As shown:

[0062] During rod delivery: By manipulating the corresponding control handle, the piston of the rod storage device lifting cylinder 2 extends or retracts, causing the lifting arm 15 and drill rod support frame 16 assembly to rise or fall to the existing horizontal position of the drill rod. Then, manipulating the corresponding control handle causes the piston rod of the rod storage device lifting cylinder 1 to extend. At this time, the rear end of the rod storage frame is higher than the front end, and the drill rod rolls outward under gravity until it stops on the drill rod support frame 16. Then, manipulating the corresponding control handle again causes the piston rod of the rod storage device lifting cylinder 2 to extend, pushing the drill rod upward to the highest position (the rod take-up position of the drilling rig's rod take-up device). After all the drill rods in this layer have been taken, manipulating the corresponding control handle causes the piston rod of the rod frame telescopic cylinder 17-1 to retract, driving the partition plate welding part 17-10 to move downward. The slot on the partition plate welding part 17-10 presses down on the corresponding partition plate 17-4, and then the partition plate 17-4 rotates upward and lifts up. Repeating the previous operation arrangement allows the drill rods of the next layer to be taken out.

[0063] During rod storage: Manipulate the corresponding control handle to extend the piston of rod storage device lifting cylinder 2, raising the lifting arm 15 and drill rod support frame 16 assembly to its highest position. After the drilling rig's rod feeder places the drill rod onto the drill rod support frame 16, manipulate the corresponding control handle to retract the piston of rod storage device lifting cylinder 2, lowering the lifting arm 15 and drill rod support frame 16 assembly to the storage compartment. Then, manipulate the corresponding control handle to retract the piston rod of rod storage device lifting cylinder 1. At this point, the rear end of the rod storage frame is lower than the front end, and the drill rod rolls inward under gravity onto the upper surface of partition plate 17-4 until it can no longer roll. After this layer of drill rods is full, manipulate the corresponding control handle to extend the piston rod of rod frame telescopic cylinder 17-1, causing the partition plate pressure plate welded part 17-10 to move upward. Under gravity, partition plate 17-4 rotates downward, and the lower arc groove of partition plate 17-4 matches the outer circle of the drill rod to limit its movement. Repeat the above process until the storage rack is full.

[0064] In this embodiment, two tie rods 18 are symmetrically arranged at both ends of the upper part of the storage rod frame 14, and the two ends of each tie rod 18 are fixedly connected to the storage rod frame 14 by safety pins 13. During transportation, the tie rods 18 are installed in place and the safety pins 13 are inserted to ensure the overall strength of the storage rod frame during transportation.

[0065] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
