DETAILED DESCRIPTION

[0020] The following will be combined with the Figures 1 to 10 The technical solutions of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention provides a hole-opening device for oil and gas pipelines through improvement. Figures 1-10 As shown, it includes an operating table 1, on which a moving plate 8 is movably provided, and an installation cavity 53 is provided on the moving plate 8, in which a turning cylinder 14 is movably installed, and a positioning shaft 16 is fixedly provided on the top of the turning cylinder 14, and multiple groups of clamping cylinders 17 are installed on the outer wall of the positioning shaft 16, and 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 pipeline 24; a punching cavity 20 is also provided on the operating table 1, and a moving frame 28 is movably provided at the bottom of the punching cavity 20; a punching ring 30 coaxial with the supporting arc plate 18 is fixedly provided on the inner side of the moving frame 28, and multiple groups of drilling rigs 33 are movably installed inside the punching ring 30; a main conical cylinder 36 and a sub-conical cylinder 39 cooperating with the drilling rig 33 are movably installed on the inner side of the moving frame 28, and the main conical cylinder 36 and the sub-conical cylinder 39 cooperate with each other to adjust the punching mode of the drilling rig 33.

[0022] In this embodiment, the drilling equipment for oil and gas pipelines consists of four main components: a movable plate 8, a movable frame 28, a primary cone 36, and a secondary cone 39. To use the equipment, the movable plate 8 and movable frame 28 are first moved apart to free up space for clamping and drilling the pipe 24. The pipe 24 to be processed is then placed on the support base 22 using external lifting equipment. Once the pipe 24 is positioned, the adjusting motor 3 drives the movable plate 8 inward, allowing the positioning shaft 16 to extend 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 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 multiple points of the pipe 24 need to be drilled simultaneously, the primary cone 36 and secondary cone 39 are connected as a single unit via the driving motor 49, and the drilling cylinder 51 is then activated. When the drive arm 52 drives the main cone 36 and the auxiliary cone 39 inward, the multiple drills 33 move synchronously toward the center. When a single hole is required in the pipe 24, the auxiliary cone 39 is made into an independent structure by the drive motor 49, and then the drilling cylinder 51 is activated. When the drive arm 52 drives the auxiliary cone 39 inward, the single drill 33 in the auxiliary cone 39 moves toward the center.

[0023] See attached Figure 1 -Attached Figure 4 Two groups of fixed vertical plates 2 are provided on the operating table 1, and an adjusting motor 3 is installed on the outer wall of one group of fixed vertical plates 2. An adjusting screw 4 is provided at the output end of the adjusting motor 3; a threaded seat 9 that cooperates with the adjusting screw 4 is provided on the moving plate 8.

[0024] In this embodiment, during the drilling operation, in order to adjust the position of the moving plate 8 relative to the fixed vertical plate 2 according to demand, an adjusting motor 3 structure is designed.

[0025] See attached Figure 3 -Attached 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 groups of limiting grooves 11 on its surface; a linkage cylinder 10 that cooperates with the linkage shaft 5 is movably installed on the movable plate 8, and the inner wall of the linkage cylinder 10 is provided with multiple groups of protrusions 12 that cooperate with the limiting grooves 11; a driving wheel 13 is fixedly provided on the outer wall of the linkage cylinder 10, and a second belt 15 is connected to the driving wheel 13, and the driving wheel 13 is movably connected to the turning cylinder 14 through the second belt 15.

[0026] In this embodiment, to ensure that the linkage shaft 5 remains in a linked state with the moving plate 8 as it moves, a mutually cooperating retaining groove 11 and protrusion 12 are provided. To synchronously drive the turning drum 14 to rotate, thereby rotating the pipe 24 during the drilling operation, a driving pulley 13 is movably connected to the turning drum 14 via a second belt 15.

[0027] See attached Figure 1 -Attached Figure 3 A rotating motor 6 is also installed on the fixed vertical plate 2 , and the output end of the rotating motor 6 is connected to a first belt 7 , and the rotating motor 6 is connected to the linkage shaft 5 through the first belt 7 .

[0028] In this embodiment, a rotating motor 6 is provided to drive the linkage shaft 5 and the turning cylinder 14 to rotate synchronously.

[0029] See attached Figure 1 -Attached Figure 2 A suspension 21 is fixedly provided at the bottom of the operating table 1, a support seat 22 is provided on the suspension 21, and multiple groups of rollers 23 cooperating with pipes 24 are movably installed on the support seat 22.

[0030] In this embodiment, a support seat 22 is designed to install and support the pipe 24 before and during the drilling operation.

[0031] See attached Figure 6 -Attached Figure 7 A support frame 25 located below the punching chamber 20 is fixedly provided at the bottom of the operating table 1, and a symmetrical conveying motor 26 is installed on the outer wall of the support frame 25. A conveying screw 27 is provided at the output end of the conveying motor 26, and a moving seat 29 threadedly connected to the conveying screw 27 is provided at the bottom of the moving frame 28.

[0032] 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 conveying motor 26 structure is designed.

[0033] See attached Figure 7 -Attached Figure 8 A plurality of mounting seats 31 are provided on the outer wall of the punching ring 30, and a reset groove 32 is opened on the mounting seat 31, and the drill rig 33 is movably installed in the reset groove 32; a protrusion 34 is provided at the end of the drill rig 33, and a reset spring 35 is provided on the outer sleeve of the drill rig 33.

[0034] In this embodiment, when the main conical cylinder 36 and the auxiliary conical cylinder 39 move inward relative to the moving frame 28, they squeeze the drill 33, causing the drill 33 to move toward the center along the return groove 32. This compresses the return spring 1 35. When the main conical cylinder 36 and the auxiliary conical cylinder 39 move outward and return to their original positions, the return spring 1 35 acts to move the drill 33 outward along the return groove 32 and return to its original position.

[0035] See attached Figure 6 -Attached Figure 9 The inner wall of the main conical tube 36 is provided with multiple groups of first grooves 37 that cooperate with the drilling rig 33, and the inner wall of the auxiliary conical tube 39 is provided with a second groove 40 that cooperates with one group of drilling rigs 33. A notch 38 is provided on the main conical tube 36, and the auxiliary conical tube 39 is movably set at the notch 38; multiple groups of sliding rods 43 are fixedly set on the inner side of the moving frame 28, a telescopic seat 41 that cooperates with the sliding rod 43 is provided on the main conical tube 36, and a telescopic seat 42 that cooperates with the sliding rod 43 is provided on the auxiliary conical tube 39. The outer sleeve of the sliding rod 43 is provided with a return spring 44.

[0036] In this embodiment, a notch 38 is formed in the main conical tube 36, and the main conical tube 36 and the auxiliary conical tube 39 form a complete conical tube mechanism. Because the first groove 37 and the second groove 40 are both inclined, when the main conical tube 36 and the auxiliary conical tube 39 move inward, the protrusion 34 slides along the first and second grooves 37 and 40, thereby driving the drill 33 toward the center relative to the punching ring 30. To enable the main conical tube 36 and the auxiliary conical tube 39 to reciprocate relative to the moving frame 28 and automatically return to their original position, a return spring 44 is mounted on the exterior of the slide rod 43.

[0037] See attached Figure 8 -Attached Figure 10 A main T-slot 45 is provided on the top outer wall of the main conical cylinder 36, and a secondary T-slot 46 is provided on the top outer wall of the secondary conical cylinder 39. A half gear ring 47 is movably installed on the top of the main conical cylinder 36 and the secondary conical cylinder 39, and a T-shaped seat 48 is provided at the bottom of the half gear ring 47. The half gear ring 47 is movably set in the main T-slot 45 and the secondary T-slot 46 through the T-shaped seat 48; a drive motor 49 is also installed on the outer wall of the main conical cylinder 36, and a gear 50 meshing with the half gear ring 47 is installed at the output end of the drive motor 49.

[0038] In this embodiment, when multiple holes are to be drilled in the pipe 24, the drive motor 49 drives the half ring gear 47 to rotate along the main T-slot 45 and the secondary T-slot 46, thereby making the main cone 36 and the secondary cone 39 a linked whole. When a single hole is to be drilled in the pipe 24, the drive motor 49 drives the half ring gear 47 away from the secondary T-slot 46, thereby making the secondary cone 39 an independently movable unit.

[0039] See attached Figure 1 -Attached Figure 2 and attached Figure 6 -Attached Figure 7 A punching cylinder 51 is also installed on the motion frame 28, and a driving arm 52 for compressing the secondary conical cylinder 39 is provided at the output end of the punching cylinder 51; a control panel 19 is also provided on the outer wall of the operating table 1.

[0040] In this embodiment, when the half gear ring 47 binds the main cone 36 and the secondary cone 39 together, they become a linked unit. When the drive arm 52 compresses the secondary cone 39 inward, the inclined first groove 37 and second groove 40 drive the multiple drills 33, which then move along the punching ring 30 toward the center and punch multiple holes in the pipe 24. When the half gear ring 47 separates the secondary cone 39 from the main cone 36, the secondary cone 39 becomes an independent moving unit. When the drive arm 52 compresses the secondary cone 39 inward, the second groove 40 drives the single drill 33, which then moves along the punching ring 30 toward the center and punches a single hole in the pipe 24. A control panel 19 is provided to control the operation of the device.

[0041] The working principle of the present invention is as follows: When using the device, the movable plate 8 and movable frame 28 are first moved apart to free up space for clamping and drilling the pipe 24. The pipe 24 to be processed is then placed on the support base 22 using external lifting equipment. Once the pipe 24 is in place, the adjusting motor 3 drives the movable plate 8 inward, allowing the positioning shaft 16 to extend into the interior of the pipe 24. Finally, the clamping cylinder 17 is activated, and the multiple sets of supporting arc plates 18 are used to position and clamp the inner wall of the pipe 24. The conveying motor 26 is then activated, and the position of the punching ring 30 relative to the pipe 24 is adjusted. When multiple points of the pipe 24 need to be drilled simultaneously, the main cone 36 and the auxiliary cone 39 are connected as a coordinated whole by the drive motor 49. The drilling cylinder 51 is then activated. As the drive arm 52 drives the main cone 36 and the auxiliary cone 39 inward, the multiple sets of drilling rigs 33 move synchronously toward the center. When a single point drilling is required on the pipe 24, the auxiliary cone 39 is made into an independent structure by driving the motor 49, and then the drilling cylinder 51 is started. When the driving arm 52 drives the auxiliary cone 39 to move inward, the single drill rig 33 in the auxiliary cone 39 moves toward the center position.
