Description

An oil drill uses a drill pipe rack Technical Field

[0001] This utility model belongs to the field of drill pipe rack technology, and in particular relates to a drill pipe rack for oil drilling. Background Technology

[0002] Drill pipe racks are equipment used in oil drilling operations to support, fix, and manage drill pipes and other tubing. They can improve the stability of the drill pipe, reduce swaying and displacement of the drill pipe caused by factors such as wind and vibration, and ensure the efficiency and safety of drilling operations.

[0003] When using existing drilling rigs with drill pipe frames, the uprights cannot be adjusted. When the rotating rod encounters hard rocks and cannot be fixed, the frame structure becomes incomplete, and the instability of individual uprights affects the overall stability. The unstable pile frame and non-vertical drill pipe guide can lead to drilling deviation and affect work efficiency.

[0004] The existing patent (application number: CN202323603745.0) describes a drill using a drill pipe frame. By rotating a knob, the bolts rotate along the adjusting block, which serves an adjustment function and enables the clamping plate to clamp. The limiting post slides along the clamping ring, which serves a limiting function and prevents the clamping plate from rotating with the bolts. With the addition of a sponge pad, a cushioning effect is achieved.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in actual use, operators need to rotate multiple sets of knobs to move multiple sets of clamping plates to fit against the sidewall of the drill pipe, which is time-consuming and labor-intensive. Improvements are needed. Therefore, a drill pipe rack for oil drilling is proposed. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4. This utility model provides a technical solution:

[0028] A drill pipe rack for an oil drilling rig includes a disc 1 with a circular opening 2 in the center. An annular opening 3 is located on the top surface of the disc 1, and a ring 4 is disposed within the annular opening 3. Evenly distributed drive blocks 5 are fixedly mounted on the ring 4. Vertical rods 6 are fixedly mounted on the bottom of each drive block 5 and slide vertically on the disc 1. Evenly distributed movable blocks 7 are disposed within the annular opening 3, with their sides fitting against the sides of the drive blocks 5. The surfaces of the movable blocks 7 and drive blocks 5 are configured as matching inclined surfaces. Movable rods 8 are fixedly mounted on the sides of each movable block 7 and slide horizontally. Placed on the disc 1, the passage 2 is provided with evenly distributed clamping plates 9. The clamping plates 9 are arc-shaped and are respectively fixedly installed at the ends of the movable rods 8. The bottom of each movable block 7 is fixedly installed with a connecting plate 10. A spring 11 is fixedly installed between the disc 1 and the connecting plate 10. The bottom of the disc 1 is provided with a driving component 12 for driving the clamping plates 9 to move horizontally closer or further apart. The driving component 12 includes a lead screw 121 rotatably disposed on the bottom surface of the disc 1, a knob 122 fixedly installed at the end of the lead screw 121, and a movable ring 123 threadedly connected to the lead screw 121. The bottom ends of the vertical rods 6 are all fixedly installed with the movable ring 123.

[0029] When fixing the drill pipe during oil extraction, the drill pipe passes through the opening 2 in the middle of the disc 1;

[0030] The operator rotates knob 122, which drives screw 121 to rotate. The movable ring 123, which is threaded to screw 121, moves vertically downward along screw 121. The downward movement of movable ring 123 drives multiple sets of vertical rods 6 to slide vertically downward on disc 1 at the same time. The vertical rods 6 slide vertically downward, which drives drive block 5 and ring 4 to slide vertically downward simultaneously within annular opening 3.

[0031] Since the contact surfaces of the drive block 5 and the movable block 7 are compatible inclined surfaces, when the drive block 5 moves down, it pushes multiple sets of movable blocks 7 to move horizontally and move closer to each other through the inclined surfaces. At this time, the connecting plate 10 compresses the spring 11, and the movable block 7 drives the movable rod 8 to slide horizontally on the disc 1, thereby driving the clamping plates 9 at the ends of the movable rod 8 to move closer to each other and clamp the drill pipe around its perimeter.

[0032] Conversely, by rotating knob 122 in the opposite direction, the restoring force of spring 11 causes clamp 9 to move away from the drill pipe, thus releasing the fixation of the drill pipe.

[0033] This oil drill uses a drill pipe rack, which can easily, quickly and securely fix the drill pipe in all directions, simplifying the operation process, saving time and effort, and making it highly practical.

[0034] The side of the disc 1 is hinged with evenly distributed support columns 13, and the bottom of each support column 13 is hinged with a mounting plate 14, and a positioning stake 15 is movably mounted on the mounting plate 14.

[0035] When installing the drill pipe frame, first unfold the support column 13 around the hinge point with the side of the disc 1, adjust the angle of the support column 13 so that the mounting plate 14 is in contact with the ground, then pass the positioning pile 15 through the mounting plate 14 and drive it into the ground, use the positioning pile 15 to fix the mounting plate 14 to the ground, thereby making the support column 13 stably support the disc 1, completing the overall installation and fixing of the device, and ensuring the stability of the drill pipe frame during operation.

[0036] A pad is laid on the surface of the clamping plate 9, and the pad is made of rubber.

[0037] When the clamping plate 9 clamps the drill pipe, the rubber pads on the surface of the clamping plate 9 are in close contact with the surface of the drill pipe, increasing the friction and making it less likely for the drill pipe to slip under the fixation of the clamping plate 9, thus improving the stability of the drill pipe fixation.

[0038] The surface of the pad has evenly distributed anti-slip textures;

[0039] The evenly distributed anti-slip texture on the surface of the pad further increases the resistance to the sliding of the drill pipe, which can further improve the stability of the drill pipe fixation and ensure that the drill pipe remains fixed during operation.

[0040] The clamping plate 9 is provided with at least four evenly distributed sets;

[0041] The clamping plate 9 is provided with at least four evenly distributed sets to fix the sides of the drill pipe from multiple directions. This can more comprehensively cover the circumference of the drill pipe, subjecting it to clamping forces from multiple angles and evenly distributing the fixing pressure. This improves the comprehensiveness of fixing the sides of the drill pipe, further enhances the stability of the drill pipe fixing, and ensures the stability of the drill pipe during oil extraction operations.

[0042] Working principle:

[0043] When fixing the drill pipe during oil extraction, the drill pipe passes through the opening 2 in the middle of the disc 1;

[0044] The operator rotates knob 122, which drives screw 121 to rotate. The movable ring 123, which is threaded to screw 121, moves vertically downward along screw 121. The downward movement of movable ring 123 drives multiple sets of vertical rods 6 to slide vertically downward on disc 1 at the same time. The vertical rods 6 slide vertically downward, which drives drive block 5 and ring 4 to slide vertically downward simultaneously within annular opening 3.

[0045] Since the contact surfaces of the drive block 5 and the movable block 7 are compatible inclined surfaces, when the drive block 5 moves down, it pushes multiple sets of movable blocks 7 to move horizontally and move closer to each other through the inclined surfaces. At this time, the connecting plate 10 compresses the spring 11, and the movable block 7 drives the movable rod 8 to slide horizontally on the disc 1, thereby driving the clamping plates 9 at the ends of the movable rod 8 to move closer to each other and clamp the drill pipe around its perimeter.

[0046] Conversely, by rotating knob 122 in the opposite direction, the restoring force of spring 11 causes clamp 9 to move away from the drill pipe, thus releasing the fixation of the drill pipe.

[0047] This oil drill uses a drill pipe rack, which can easily, quickly and securely fix the drill pipe in all directions, simplifying the operation process, saving time and effort, and making it highly practical.

[0048] in,

[0049] When installing the drill pipe frame, first unfold the support column 13 around the hinge point with the side of the disc 1, adjust the angle of the support column 13 so that the mounting plate 14 is in contact with the ground, then pass the positioning pile 15 through the mounting plate 14 and drive it into the ground, use the positioning pile 15 to fix the mounting plate 14 to the ground, thereby making the support column 13 stably support the disc 1, completing the overall installation and fixing of the device, and ensuring the stability of the drill pipe frame during operation.

[0050] When the clamping plate 9 clamps the drill pipe, the rubber pads laid on the surface of the clamping plate 9 are in close contact with the surface of the drill pipe, increasing the friction and making it less likely for the drill pipe to slip under the fixation of the clamping plate 9, thus improving the stability of the drill pipe fixation.

[0051] The evenly distributed anti-slip texture on the surface of the pad further increases the resistance to the sliding of the drill pipe, which can further improve the stability of the drill pipe fixation and ensure that the drill pipe remains fixed during operation.

[0052] The clamping plate 9 is provided with at least four evenly distributed sets to fix the sides of the drill pipe from multiple directions. This can more comprehensively cover the circumference of the drill pipe, subjecting it to clamping forces from multiple angles and evenly distributing the fixing pressure. This improves the comprehensiveness of fixing the sides of the drill pipe, further enhances the stability of the drill pipe fixing, and ensures the stability of the drill pipe during oil extraction operations.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
