Description

Technical Field

[0001] This invention relates to the field of pipeline drilling technology, specifically a drilling device for oil and gas transmission pipelines. Background Technology

[0002] Oil and gas pipelines are one of the main methods for long-distance transportation of oil and gas resources, offering advantages such as large transport capacity, low energy consumption, and high safety. With the further development and exploration of oil and gas resources, the demand for pipeline engineering and oil and gas pipelines is increasing. After production, oil and gas pipelines require multiple perforations to facilitate subsequent pipeline installation and the installation of other related equipment.

[0003] Chinese patent application CN119550117A discloses a drilling device for metal corrugated pipes, including two symmetrically arranged fixed mechanisms and a guide rod fixedly connected between the two fixed mechanisms. A movable mechanism is slidably mounted on the guide rod. A drive mechanism for moving and operating the movable mechanism is mounted on the front of the movable mechanism. A clamping mechanism and a drilling mechanism are evenly distributed circumferentially on the left side of the movable mechanism. This invention uses a single power source to drive a second motor to operate a reciprocating moving component and an intermittent moving component. The second motor drives the moving gear to rotate intermittently through a dial and a grooved wheel, which can drive the movable mechanism to move intermittently to the right at equal distances. At the same time, the second motor drives the reciprocating moving component to rotate the drive gear in both directions, enabling the movable mechanism to drive the clamping mechanism and the drilling mechanism to approach the metal corrugated pipe for fixing and drilling, thereby improving drilling efficiency and reducing production costs.

[0032] The following will be combined with the appendix Figures 1 to 10 The technical solutions of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides, through improvements, a perforation device for oil and gas transmission pipelines, such as... Figures 1-10 As shown, the system includes an operating platform 1, on which a moving plate 8 is movably mounted. An installation cavity 53 is formed on the moving plate 8, and a rotating cylinder 14 is movably mounted within the installation cavity 53. A positioning shaft 16 is fixedly mounted on the top of the rotating cylinder 14. Multiple sets of clamping cylinders 17 are mounted on the outer wall of the positioning shaft 16. A supporting arc plate 18 is provided at the output end of the clamping cylinder 17, and the supporting arc plate 18 is used to position the pipe 24. The operating platform 1 also has a drilling cavity 20, and a moving frame 28 is movably mounted at the bottom of the drilling cavity 20. A drilling ring 30, coaxial with the supporting arc plate 18, is fixedly mounted on the inner side of the moving frame 28. Multiple sets of drilling rigs 33 are movably mounted inside the drilling ring 30. A main conical cylinder 36 and a secondary conical cylinder 39, which cooperate with the drilling rigs 33, are movably mounted on the inner side of the moving frame 28. The main conical cylinder 36 and the secondary conical cylinder 39 cooperate to adjust the drilling mode of the drilling rigs 33.

[0034] In this embodiment, the drilling equipment for oil and gas pipelines mainly consists of four parts: a moving plate 8, a moving frame 28, a main conical cylinder 36, and a secondary conical cylinder 39. When using the equipment, the moving plate 8 and moving frame 28 are first moved away from each other to create space for clamping and drilling the pipe 24. Then, the pipe 24 to be processed is placed on the support base 22 using external hoisting equipment. After the pipe 24 is in place, the moving plate 8 is driven inward by the adjusting motor 3, at which point the positioning shaft 16 extends into the interior of the pipe 24. Finally, the clamping cylinder 17 is activated, and multiple sets of supporting arc plates 18 are used to internally position and clamp the inner wall of the pipe 24. The conveying motor 26 is then activated, and the position of the drilling ring 30 relative to the pipe 24 is adjusted. When multi-point synchronous drilling of the pipe 24 is required, the main conical cylinder 36 and the secondary conical cylinder 39 are made into a linked whole by the drive motor 49, and then the drilling cylinder 51 is activated. When the drive arm 52 drives the main conical cylinder 36 and the secondary conical cylinder 39 to move inward, multiple drilling rigs 33 move synchronously towards the center position. When single-point drilling is required on the pipe 24, the secondary conical cylinder 39 becomes an independent structure through the drive motor 49, and then the drilling cylinder 51 is activated. When the drive arm 52 drives the secondary conical cylinder 39 to move inward, a single drilling rig 33 inside the secondary conical cylinder 39 moves towards the center position.

[0035] See appendix Figure 1 - Appendix Figure 4 The control panel 1 is equipped with two sets of fixed vertical plates 2. One set of fixed vertical plates 2 is equipped with an adjustment motor 3 on its outer wall. The output end of the adjustment motor 3 is equipped with an adjustment screw 4. The moving plate 8 is equipped with a threaded seat 9 that cooperates with the adjustment screw 4.

[0036] In this embodiment: When drilling, in order to adjust the position of the moving plate 8 relative to the fixed vertical plate 2 as needed, an adjusting motor 3 structure is designed.

[0037] See appendix Figure 3 - Appendix Figure 5 A linkage shaft 5 is movably installed between the fixed vertical plates 2. The linkage shaft 5 passes through one of the fixed vertical plates 2 and has multiple sets of limiting grooves 11 on its surface. A linkage cylinder 10 that cooperates with the linkage shaft 5 is movably installed on the moving plate 8. The inner wall of the linkage cylinder 10 is provided with multiple sets of protrusions 12 that cooperate with the limiting grooves 11. A drive wheel 13 is fixedly installed on the outer wall of the linkage cylinder 10. A second belt 15 is connected to the drive wheel 13. The drive wheel 13 is movably connected to the tilting cylinder 14 through the second belt 15.

[0038] In this embodiment: when the moving plate 8 moves, in order to keep the linkage shaft 5 in a linked state with the moving plate 8, a mutually cooperating limiting groove 11 and protrusion 12 structure is designed. In order to synchronously drive the rotating cylinder 14 to rotate, thereby rotating the pipe 24 during the drilling operation, the drive wheel 13 is movably connected to the rotating cylinder 14 through the second belt 15.

[0039] See appendix Figure 1 - Appendix Figure 3 A rotary motor 6 is also installed on the fixed vertical plate 2. The output end of the rotary motor 6 is connected to the first belt 7. The rotary motor 6 is connected to the linkage shaft 5 through the first belt 7.

[0040] In this embodiment: a rotary motor 6 structure is designed to drive the linkage shaft 5 and the tilting cylinder 14 to rotate synchronously.

[0041] See appendix Figure 1 - Appendix Figure 2 The bottom of the operating table 1 is also fixedly equipped with a suspension 21, and a support seat 22 is provided on the suspension 21. Multiple sets of rollers 23 that cooperate with the pipe 24 are movably installed on the support seat 22.

[0042] In this embodiment: Before and during the drilling operation, a support base 22 structure is designed to install and support the pipe 24.

[0043] See appendix Figure 6 - Appendix Figure 7 The bottom of the operating table 1 is fixedly provided with a support frame 25 located below the drilling cavity 20. Symmetrical conveyor motors 26 are installed on the outer wall of the support frame 25. The output end of the conveyor motor 26 is provided with a conveyor screw 27. The bottom of the motion frame 28 is provided with a motion seat 29 that is threadedly connected to the conveyor screw 27.

[0044] In this embodiment: During the drilling operation, in order to adjust the position of the moving frame 28 and drill holes at different positions of the pipe 24, a conveyor motor 26 structure is designed.

[0045] See appendix Figure 7 - Appendix Figure 8 Multiple sets of mounting seats 31 are provided on the outer wall of the drilling ring 30. The mounting seats 31 are provided with reset grooves 32. The drilling machine 33 is movably installed in the reset grooves 32. The end of the drilling machine 33 is provided with a protrusion 34. A reset spring 35 is sleeved on the outside of the drilling machine 33.

[0046] In this embodiment: when the main conical cylinder 36 and the auxiliary conical cylinder 39 move inward relative to the moving frame 28, they compress the drilling rig 33. At this time, the drilling rig 33 moves towards the center position along the reset groove 32, and the reset spring 35 is compressed. When the main conical cylinder 36 and the auxiliary conical cylinder 39 move outward and return to their original positions, the drilling rig 33 moves outward along the reset groove 32 and returns to its original position under the action of the reset spring 35.

[0047] See appendix Figure 6 - Appendix Figure 9 The inner wall of the main conical cylinder 36 has multiple sets of first grooves 37 that cooperate with the drilling rig 33. The inner wall of the secondary conical cylinder 39 has a second groove 40 that cooperates with one of the drilling rigs 33. The main conical cylinder 36 has a notch 38, and the secondary conical cylinder 39 is movably disposed at the notch 38. Multiple sets of sliding rods 43 are fixedly disposed on the inner side of the motion frame 28. The main conical cylinder 36 is provided with a telescopic seat 41 that cooperates with the sliding rod 43, and the secondary conical cylinder 39 is provided with a telescopic seat 42 that cooperates with the sliding rod 43. The sliding rod 43 is fitted with a return spring 44.

[0048] In this embodiment, a notch 38 is provided on the main conical cylinder 36, and the main conical cylinder 36 and the secondary conical cylinder 39 form a complete conical cylinder mechanism. Since both the first groove 37 and the second groove 40 are inclined structures, when the main conical cylinder 36 and the secondary conical cylinder 39 move inward, the protrusion 34 slides along the first groove 37 and the second groove 40, thereby driving the drill rig 33 to move towards the center position relative to the drilling ring 30. In order to enable the main conical cylinder 36 and the secondary conical cylinder 39 to reciprocate relative to the motion frame 28 and automatically return to their original positions, a return spring 44 is sleeved on the outside of the slide rod 43.

[0049] See appendix Figure 8 - Appendix Figure 10 The main conical cylinder 36 has a main T-slot 45 on its top outer wall, and the secondary conical cylinder 39 has a secondary T-slot 46 on its top outer wall. A semi-gear ring 47 is movably mounted on the top of the main conical cylinder 36 and the secondary conical cylinder 39. A T-slot 48 is provided at the bottom of the semi-gear ring 47. The semi-gear ring 47 is movably mounted in the main T-slot 45 and the secondary T-slot 46 through the T-slot 48. A drive motor 49 is also installed on the outer wall of the main conical cylinder 36. A gear 50 that meshes with the semi-gear ring 47 is installed at the output end of the drive motor 49.

[0050] In this embodiment: when multiple holes need to be drilled in the pipe 24, the drive motor 49 drives the semi-gear ring 47 to rotate along the main T-slot 45 and the secondary T-slot 46, thereby making the main conical cylinder 36 and the secondary conical cylinder 39 a linked whole. When a single hole needs to be drilled in the pipe 24, the drive motor 49 drives the semi-gear ring 47 to disengage from the secondary T-slot 46, thereby making the secondary conical cylinder 39 an independent moving body.

[0051] See appendix Figure 1 - Appendix Figure 2 and attached Figure 6 - Appendix Figure 7 The motion frame 28 is also equipped with a punching cylinder 51, and the output end of the punching cylinder 51 is provided with a drive arm 52 to compress the secondary conical cylinder 39; the outer wall of the operating table 1 is also provided with a control panel 19.

[0052] In this embodiment: after the semi-gear ring 47 binds the main conical cylinder 36 and the secondary conical cylinder 39 together, the main conical cylinder 36 and the secondary conical cylinder 39 become a linked whole. When the drive arm 52 compresses the secondary conical cylinder 39 inward, the inclined first groove 37 and the second groove 40 drive multiple sets of drills 33. At this time, the multiple sets of drills 33 move along the drilling ring 30 towards the center position and drill multiple points in the pipe 24. When the semi-gear ring 47 disengages the secondary conical cylinder 39 from the main conical cylinder 36, the secondary conical cylinder 39 becomes an independent moving body. When the drive arm 52 compresses the secondary conical cylinder 39 inward, the second groove 40 drives a single set of drills 33. At this time, the drill 33 moves along the drilling ring 30 towards the center position and drills a single point in the pipe 24. To control the operation of the equipment, a control panel 19 structure is designed.

[0053] The working principle of this invention is as follows: When using the equipment, the moving plate 8 and moving frame 28 are first moved away from each other to create space for clamping and drilling the pipe 24. Then, the pipe 24 to be processed is placed on the support base 22 using external hoisting equipment. After the pipe 24 is in place, the moving plate 8 is driven inward by the adjusting motor 3. At this time, the positioning shaft 16 extends into the interior of the pipe 24. Finally, the clamping cylinder 17 is activated, and multiple sets of supporting arc plates 18 are used to internally position and clamp the inner wall of the pipe 24. The conveying motor 26 is then activated, and the position of the drilling ring 30 relative to the pipe 24 is adjusted. When multi-point synchronous drilling of the pipe 24 is required, the main conical cylinder 36 and the auxiliary conical cylinder 39 are made into a linked whole by the drive motor 49, and then the drilling cylinder 51 is activated. When the drive arm 52 drives the main conical cylinder 36 and the auxiliary conical cylinder 39 inward, multiple drilling rigs 33 move synchronously towards the center position. When single-point drilling is required on pipe 24, the auxiliary conical cylinder 39 is made into an independent structure by driving motor 49, and then the drilling cylinder 51 is activated. When the drive arm 52 drives the auxiliary conical cylinder 39 to move inward, the single drilling rig 33 inside the auxiliary conical cylinder 39 moves towards the center position.
