Description

Technical Field

[0001] This invention relates to the field of petroleum equipment technology, specifically to a ground-based single-root integrated treatment method and device. Background Technology

[0002] As a key technology to ensure the efficient operation of oil wells in the mid-to-late stages of oil and gas field development, pressurized operations can complete wellbore maintenance, reservoir stimulation and other operations without well control or blowout, avoiding contamination of the reservoir by well control fluid, reducing resource waste and significantly shortening the operation cycle.

[0003] Before performing live-line work, the tubing requires a series of pretreatment operations, including disassembling the end protector, gauging and cleaning, thread cleaning, length measurement, drying, thread inspection, and inkjet marking. Currently, these processes are typically completed in steps by multiple independent pieces of equipment, such as: a protector removal machine, a gauging machine, a cleaning machine, a length measuring instrument, a dryer, a thread inspector, and an inkjet printer. These devices are scattered, have single functions, and lack effective integration and coordination. Operators need to repeatedly hoist and move the tubing between these devices, which is not only lengthy and time-consuming, but also prone to damaging the tubing surface and threads due to repeated clamping.

[0004] In the existing technology, a Chinese invention patent published on August 3, 2018, with publication number CN108362245A and titled "An Integrated Machine for Drilling Site Pipeline Inspection," integrates functions such as thread cleaning, diameter detection, length measurement, and inkjet marking into a single device. However, the overall structure and application mode of the existing integrated solution still have the following shortcomings: Firstly, this all-in-one machine only integrates four processes: thread cleaning, diameter detection, length measurement, and inkjet marking. It does not cover equally necessary pre-treatment processes such as wire removal, drying, and thread detection. After the oil pipe is processed, it still needs to be transferred to other equipment for the remaining processes.

[0005] Secondly, the existing integrated solution adopts a fixed-point operation mode, that is, after the oil pipe is fixed inside the equipment, each functional module moves to the oil pipe position in sequence to complete the operation. In this mode, the processes are sequential, and only one workstation is in operation at any given time, while other functional modules are in a waiting state, resulting in low equipment utilization and low operation efficiency.

[0006] Third, in the existing integrated solution, the functional modules and the handling mechanism are arranged separately—the functional modules are installed on the equipment base, while the handling mechanism is set up independently on the outside. There is a lack of a unified installation foundation and layout plan between the two. The flow of oil pipes between various processes depends entirely on the cross-regional transport of the external handling mechanism. This not only increases the process connection time and the overall space occupied, but also limits the alignment accuracy between the functional modules and the handling mechanism due to their independent installation state, making it difficult to guarantee the accurate positioning of the oil pipes between various workstations.

[0007] Fourth, there is a lack of automated connection between loading and unloading. Whether it is a standalone device or an integrated machine, the loading and unloading of oil pipes still rely on manual hoisting or external robotic arms. The entire process from feeding to pre-processing to delivery has not been fully automated, and there are many manual intervention links, which affects the overall operation efficiency. Summary of the Invention

[0008] To address the problems of incomplete process coverage, low efficiency of fixed-point operations, and limited flow caused by the separate arrangement of functional modules and handling mechanisms in existing integrated equipment, this invention provides a ground-based single-pipe integrated processing method and device.

[0017] Furthermore, the transmission mechanism includes a synchronous shaft, a driving bevel gear, a driven bevel gear, a main gear, and a secondary gear; the output end of the servo motor is connected to one end of the synchronous shaft via the torque clutch; several driving bevel gears are fixedly mounted on the synchronous shaft; the traveling wheel assembly includes multiple pairs of driving guide rollers and driven guide rollers, the driving guide rollers and the driven guide rollers being located on both sides of the hose delivery path; each driving guide roller is coaxially fixedly connected to a driven bevel gear and a main gear, the driven bevel gear meshing one-to-one with the driving bevel gear on the synchronous shaft; each driven guide roller is coaxially fixedly connected to a secondary gear, the main gear meshing one-to-one with the secondary gear.

[0018] Furthermore, the gauge receiving end includes a gauge receiving mechanism and a sensor for sensing whether the gauge has reached the receiving end.

[0019] Furthermore, the first thread cleaning unit is an external thread cleaning unit, and the second thread cleaning unit is an internal thread cleaning unit; the first thread cleaning unit includes a cleaning motor, a transmission gear set, a high-pressure rotary joint, and an external thread cleaning head. The external thread cleaning head includes a brush set and a water spray pipe, both of which are evenly distributed along the circumference of the external thread cleaning head; the transmission gear set is fixedly connected to the external thread cleaning head; the high-pressure rotary joint passes through the center of the transmission gear set and the external thread cleaning head, with its rear end stationary and connected to a high-pressure water pipe, and its front end connected to the water spray pipe; the cleaning motor drives the external thread cleaning head to rotate through the transmission gear set.

[0020] Furthermore, the first coarse centering unit and the second coarse centering unit have the same structure, both including a centering shell, a moving rod, a baffle, an oil pipe cover, and a spring; the moving rod passes through the centering shell and can slide relative to it, the front end of the moving rod extends out of the centering shell and is fixedly connected to the oil pipe cover, and the rear end is connected to the baffle fixed to the rear end of the centering shell through the spring.

The forward and backward motor drives the clamping and rotating mechanism to move back and forth as a whole through the forward and backward lead screw; The clamping opening and closing motor drives the two jaws to move synchronously towards or away from each other via the clamping opening and closing screw to clamp or release the oil pipe. The rotary motor drives the rotary roller to rotate through the gear transmission pair, thereby rotating the oil pipe.

[0025] Furthermore, the first and second inkjet printing units have the same structure, both including an inkjet printing servo motor, an inkjet printing guide rail, an inkjet printer, and a lead screw. The inkjet printer is slidably mounted on the inkjet printing guide rail, and the inkjet printing servo motor is connected to the inkjet printer via the lead screw to drive the inkjet printer to reciprocate along the inkjet printing guide rail.

[0026] On the other hand, based on the above-mentioned ground single-root integrated treatment device, the present invention also proposes a ground single-root integrated treatment method, including: S1, Loading: The two oil pipe support frames on the loading side of the two skid-mounted structures are driven by the corresponding horizontal drive mechanism and vertical drive mechanism respectively, which simultaneously lift the same oil pipe from both ends and place the oil pipe in the clamping position of the corresponding rotary conveying component. S2. Conveying and Pre-treatment: The rotary conveying component clamps the oil pipe and drives the oil pipe to rotate in sections, conveying the oil pipe to each pre-treatment station of the functional component in sequence. When the oil pipe arrives at each station, the functional component performs pre-treatment operations simultaneously from both ends of the oil pipe. S3. Unloading: After all pre-processing is completed, the two oil pipe support frames on the unloading side of the two skid-mounted structures are driven by the corresponding horizontal drive mechanism and vertical drive mechanism respectively, and the oil pipes are lifted from both ends simultaneously, and the oil pipes are removed from the clamping position of the rotating transport assembly and transferred to the next process.

[0027] Furthermore, the pretreatment process includes, in sequence: coarse centering, wire removal, diameter and high-pressure cleaning, thread cleaning, length measurement, drying, thread inspection and coding.

[0028] Preferably, after each station completes its current processing action, the rotary conveying assembly rotates by one station angle, and the oil pipes on each station move forward by one station simultaneously; at this time, the oil pipe located at the last station completes all preprocessing and moves out, while the first station becomes vacant, and the next oil pipe enters the first station; multiple oil pipes are processed in parallel at different stations, forming a continuous assembly line operation.

[0029] In summary, the present invention has the following advantages: 1. This invention integrates the integrated base frame, loading and unloading handling components, rotating handling components and functional components into a single device, realizing continuous automated operation from pipe picking, full-process pre-processing to delivery, without the need for manual hoisting intervention, greatly shortening the operation chain and reducing manpower input.

[0030] 2. In this invention, the loading and unloading conveying component and the rotary conveying component work together. The loading and unloading conveying component simultaneously lifts the oil pipe from both ends and places it on the rotary conveying component. The rotary conveying component clamps the oil pipe and drives it to rotate in sections, so that the oil pipe passes through each pre-processing station in sequence, realizing the automatic flow of a single oil pipe between stations without relying on external conveying equipment.

[0031] 3. In this invention, the functional components are arranged with multiple pre-processing stations in sequence along the circumference, and the rotary conveying component has multiple clamping positions arranged along the circumference on the conveying turntable, which can clamp multiple oil pipes simultaneously for parallel processing. Each time the conveying turntable rotates by one station angle, each oil pipe moves forward by one station synchronously. The discharge cycle of a single oil pipe is equal to the processing time of the slowest station, rather than the sum of the times of each station. The equipment utilization rate is high, and the batch processing efficiency is greatly improved.

[0032] 4. In this invention, the functional component consists of two opposing arc mounting bases. The corresponding units on both sides are arranged opposite each other along the axial direction and are processed synchronously from both ends of the oil pipe at the same work station. The processing time of a single oil pipe is reduced by half, avoiding off-center load or positioning error caused by asynchronous processing at both ends.

[0033] 5. In this invention, the spacing between the two skid-mounted structures is adjustable, and the integrated base frame achieves overall leveling through bottom lifting jacks and angle sensors, which can flexibly adapt to the processing needs of oil pipes of different lengths and ensure operational accuracy.

[0034] 6. In this invention, the loading and unloading conveying assembly is fixedly installed on the skid-mounted structure and moves synchronously with the skid-mounted structure. When the two skid-mounted structures adjust the distance to accommodate oil pipes of different lengths, the loading and unloading conveying assembly always maintains the correct relative position with the rotating conveying assembly, ensuring the accuracy of loading and unloading actions.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Example 1 This embodiment provides a ground-based single-root integrated treatment method and device, such as Figure 1 As shown, the device includes an integrated base frame 61, on which two skid-mounted structures are arranged opposite each other, and the distance between the two skid-mounted structures is adjustable. Each skid-mounted structure is sequentially equipped with a functional component, a rotary conveying component 4, and a loading / unloading conveying component 71. That is, from the left end to the right end of the integrated base frame 61, the sequence is: functional component, rotary conveying component 4, loading / unloading conveying component 71, loading / unloading conveying component 71, rotary conveying component 4, and functional component.

[0039] like Figure 20 As shown, the integrated base frame 61 includes a bottom frame 611, with bottom lifting jacks 617 installed at each of the four corners of the bottom frame 611. The bottom lifting jacks 617, in conjunction with angle sensors, level the bottom frame 611 as a whole. Two bottom guide rails 612 and a bottom toothed rail 613 are arranged parallel to each other along the length of the top surface of the bottom frame 611. A bottom rack 614 is installed on one side of the bottom toothed rail 613.

[0040] The skid-mounted structure has a skid-mounted mounting base 615 at its bottom, which spans the bottom guide rail 612 and the bottom rack 613 and can move along the length of the bottom guide rail 612. A skid-mounted drive motor 616 is mounted on the skid-mounted mounting base 615, and a skid-mounted drive gear is provided at the output end of the skid-mounted drive motor 616. The skid-mounted drive gear meshes with the bottom rack 614 to drive the skid-mounted structure to move along the bottom guide rail 612.

[0041] like Figure 1As shown, the functional components include a first arc-shaped mounting base 1a and a second arc-shaped mounting base 1b arranged opposite each other, with the two arc-shaped mounting bases coaxially arranged. The first arc-shaped mounting base 1a has, along its circumferential direction, a first coarse alignment unit 51, a first wire removal unit 52, a first bore cleaning unit 21, a first thread cleaning unit 31, a first length measuring unit 53, a first drying unit 54, a first thread detection unit 55, and a first coding unit 56. The second arc-shaped mounting base 1b has, along its circumferential direction, a second coarse alignment unit, a second wire removal unit, a second bore cleaning unit 22, a second thread cleaning unit 32, a second length measuring unit, a second drying unit, a second thread detection unit, and a second coding unit. The paired units (such as the first coarse alignment unit 51 and the second coarse alignment unit) are arranged opposite each other along the axial direction of the tubing, respectively performing operations on the corresponding ends of the tubing from both ends.

[0042] like Figure 2 As shown, each unit is slidably mounted on its corresponding arc-shaped mounting base via guide rail pairs. Each unit is equipped with an independent drive mechanism (such as a servo motor with a lead screw, or a cylinder), which can slide independently along the oil pipe axis to achieve precise alignment or reset of each unit with the oil pipe port. The position of each unit on the arc-shaped mounting base corresponds one-to-one with the indexing positions of the rotary conveying assembly 4. As the oil pipe rotates with the rotary conveying assembly 4, it passes through the working positions of each unit in sequence.

[0043] like Figure 19 As shown, the loading and unloading conveying assembly 71 includes a conveying base 712 fixedly mounted on a skid-mounted structure. Horizontal conveying guide rails are respectively provided on two sides of the conveying base 712, and a conveying lifting seat 714 is slidably fitted on each horizontal conveying guide rail. Two horizontal push motors 711 are correspondingly provided on the conveying base 712. Each horizontal push motor 711 is driven by a corresponding horizontal lead screw 713 to drive the conveying lifting seat 714 to move along the corresponding horizontal conveying guide rail. Each conveying lifting seat 714 is provided with a vertical conveying guide rail 715, and a hydraulic pipe support seat 716 is slidably fitted on the vertical conveying guide rail 715. A hydraulic pipe support frame 717 is provided on one side of the hydraulic pipe support seat 716. A vertical push motor 719 is provided at the top of each conveying lifting seat 714. The vertical push motor 719 is driven by a corresponding vertical lead screw 718 to drive the hydraulic pipe support seat 716 to rise and fall along the corresponding vertical conveying guide rail 715.

[0044] Therefore, each loading and unloading conveying assembly 71 includes two oil pipe support frames 717 located on the loading side and the unloading side, respectively. Each oil pipe support frame 717 has independent horizontal and vertical degrees of freedom of movement. The two oil pipe support frames 717 on the loading side of the two skid-mounted structures work together to lift the oil pipe, move the oil pipe from the picking position and place it on the clamping position of the rotary conveying assembly 4 to complete the loading. The two oil pipe support frames 717 on the unloading side of the two skid-mounted structures work together to lift the oil pipe that has completed all pre-processing, move the oil pipe from the clamping position of the rotary conveying assembly 4 to the next process to complete the unloading.

[0045] In this embodiment, the horizontal drive mechanism uses a horizontal drive motor 711 in conjunction with a horizontal lead screw 713 to achieve linear drive, and the vertical drive mechanism uses a vertical drive motor 719 in conjunction with a vertical lead screw 718 to achieve linear drive. In other embodiments, the horizontal and vertical drive mechanisms can also use conventional linear drive structures such as cylinders, hydraulic cylinders, gear racks, or synchronous belts, as long as they can achieve the corresponding linear motion.

[0046] like Figures 15 to 17 As shown, the rotary conveying assembly 4 includes a conveying turntable 41 that can rotate around its own axis and multiple sets of conveying clamping assemblies 42 evenly arranged around the circumference of the conveying turntable 41. Two conveying turntables 41 are respectively disposed on opposite sides of two arc-shaped mounting bases and are coaxially arranged. The conveying clamping assemblies 42 on the two conveying turntables 41 cooperate in pairs, clamping the same oil pipe from the left and right ends respectively. The two conveying turntables 41 are driven by their respective indexing drive motors or the same drive system, and can synchronously index and rotate around their own axes, sequentially conveying oil pipes between multiple workstations.

[0047] Each set of transport and clamping components 42 includes two clamping blocks 421, a clamping frame 422, a clamping block guide rail 423, a clamping drive motor 424, a clamping screw 425, and a clamping gear set 426. The clamping frame 422 is fixedly mounted on the transport turntable 41, the clamping block guide rail 423 is fixedly mounted on the top of the clamping frame 422, and the clamping drive motor 424 is fixedly mounted on the bottom of the clamping frame 422. The clamping screw 425 is rotatably mounted inside the clamping frame 422, and its two ends have external threads with opposite directions of rotation. The output shaft of the clamping drive motor 424 is connected to one end of the clamping screw 425 via the clamping gear set 426. The two clamping blocks 421 are slidably mounted on the clamping block guide rail 423, and a connecting rod 427 is fixedly connected to the bottom of each clamping block 421. These two connecting rods 427 are threadedly engaged with both ends of the clamping screw 425, respectively.

[0048] When the clamping drive motor 424 rotates, the clamping screw 425 rotates synchronously. Because the threads at both ends of the clamping screw 425 rotate in opposite directions, the two clamping blocks 421 slide towards each other (clamping the oil pipe) or slide away from each other (releasing the oil pipe) in a direction perpendicular to the oil pipe axis under the guidance of the clamping block guide rail 423.

[0049] In this embodiment, the rotary conveying assembly 4 includes two coaxially arranged conveying turntables 41, which are coaxially engaged with the first arc mounting base 1a and the second arc mounting base 1b, respectively. Multiple sets of conveying clamping assemblies 42 are evenly arranged circumferentially on the two conveying turntables 41, and the position of each conveying clamping assembly 42 corresponds one-to-one with the indexing position of each unit on the first arc mounting base 1a and the second arc mounting base 1b. The oil pipe is clamped between the corresponding conveying clamping assemblies 42 on the two conveying turntables 41. During operation, the two conveying turntables 41 synchronously rotate around their own axes, sequentially conveying the oil pipe to the corresponding positions of each unit.

[0050] The first diameter cleaning unit 21 is the diameter pushing end, and the second diameter cleaning unit 22 is the diameter receiving end. The two are arranged opposite each other along the axial direction to work together to complete the diameter detection and high-pressure cleaning of the inner wall of the oil pipe.

[0051] like Figures 3 to 5 As shown, the gauging pusher includes a slide 212 and a forward / reverse module, a hose, a guide assembly 218, a rotating nozzle 214, and a gauging gauge 216 mounted on the slide 212. The slide 212 is slidably mounted on the guide rail of the arc mounting base and is driven by a power unit 211, which can drive the entire gauging pusher to slide along the oil pipe axis to achieve precise alignment or resetting with the oil pipe port.

[0052] The guide assembly 218 guides the hose to move stably along the axial direction of the tubing, preventing the hose from bending or deviating during travel. The guide assembly 218 includes a first guide cylinder and a second guide cylinder. The first guide cylinder is located on the inlet side of the travel wheel assembly 2133, and the second guide cylinder is located on the outlet side of the travel wheel assembly 2133. The center lines of the first and second guide cylinders are coaxial with the center line of the travel wheel assembly 2133. The front end of the hose passes sequentially through the first guide cylinder, the travel wheel assembly 2133, and the second guide cylinder, and connects to the rotating nozzle 214. The rotating nozzle 214 has an external axial support, and the front end of this axial support has an end plug 215. A gauge 216 is detachably mounted on the center of the end plug 215. The rear end of the hose is connected to a high-pressure water source. High-pressure water is delivered to the rotating nozzle 214 through the hose, and the water pressure drives the rotating nozzle 214 to rotate autonomously, creating a high-pressure scouring effect on the inner wall of the tubing.

[0053] The forward and backward module includes a servo motor 2131, a torque clutch 2132, a transmission mechanism, and a set of traveling wheels 2133. The output end of the servo motor 2131 is connected to the transmission mechanism through the torque clutch 2132, and the transmission mechanism is rotatably connected to the set of traveling wheels 2133.

[0054] Specifically, the transmission mechanism includes a synchronous shaft 2134, a driving bevel gear 2135, a driven bevel gear 2136, a main gear 2137, and a secondary gear. The output end of the servo motor 2131 is connected to one end of the synchronous shaft 2134 via a torque clutch 2132. Several driving bevel gears 2135 are fixedly mounted on the synchronous shaft 2134. The travel wheel assembly 2133 includes multiple pairs of driving guide rollers and driven guide rollers, which are located on both sides of the hose conveying path. Each driving guide roller has a driven bevel gear 2136 and a main gear 2137 coaxially fixedly connected, with the driven bevel gear 2136 meshing one-to-one with the driving bevel gear 2135 on the synchronous shaft 2134; each driven guide roller has a secondary gear coaxially fixedly connected, with the main gear 2137 meshing one-to-one with the secondary gear.

[0055] During operation, the servo motor 2131 drives the synchronous shaft 2134 to rotate through the torque clutch 2132. The active bevel gear 2135 on the synchronous shaft 2134 drives the driven bevel gear 2136 and the active guide roller to rotate. The active guide roller drives the driven guide roller to rotate synchronously in the opposite direction through the meshing of the main gear 2137 and the driven gear. The paired active guide roller and driven guide roller clamp the hose and drive the hose to move forward or backward stably along the axial direction.

[0056] like Figure 6 As shown, the tube push end is also equipped with a tube winder 217, which is used to release or retract the tube synchronously with the forward or backward movement of the hose, so as to prevent the hose from getting tangled or excessively bent during the movement.

[0057] like Figure 7 As shown, the gauge receiving end includes a gauge receiving mechanism 221 and a sensor. The gauge receiving mechanism 221 is used to receive the gauge 216 that passes through the other end of the oil pipe. The sensor (such as a proximity switch or photoelectric sensor) is disposed on the gauge receiving mechanism 221 to sense whether the gauge 216 has reached the receiving end.

[0058] The working process of the first diameter cleaning unit 21 and the second diameter cleaning unit 22 is as follows: The gauge pusher slides to align with one end of the oil pipe, and the gauge receiver slides to align with the other end of the oil pipe. The servo motor 2131 rotates forward, driving the travel wheel assembly 2133 to rotate via the torque clutch 2132, synchronous shaft 2134, and bevel gear set. The travel wheel assembly 2133 clamps the hose and drives it forward, causing the rotating nozzle 214 and gauge 216 to pass through the oil pipe. Simultaneously, the pump starts, delivering high-pressure water through the hose to the rotating nozzle 214. The water pressure drives the rotating nozzle 214 to rotate autonomously, simultaneously flushing the inner wall of the oil pipe as the gauge 216 travels. Once the gauge 216 has traveled completely to the other end of the oil pipe, it is received by the gauge receiving mechanism 221. The sensor detects the gauge 216, and the system determines that the gauge detection is complete.

[0059] like Figure 8 As shown, the first thread cleaning unit 31 is an external thread cleaning unit, including a cleaning motor 312, a transmission gear set 313, a high-pressure rotary joint 311, and an external thread cleaning head. The external thread cleaning head includes a brush set 314 and a water spray pipe 315, both of which are evenly distributed along the circumference of the external thread cleaning head. The transmission gear set 313 is fixedly connected to the external thread cleaning head. The high-pressure rotary joint 311 passes through the center of the transmission gear set 313 and the external thread cleaning head, with its rear end stationary and connected to the high-pressure water pipe, and its front end connected to the water spray pipe 315. The cleaning motor 312 drives the external thread cleaning head to rotate through the transmission gear set 313. During operation, high-pressure water enters each water spray pipe 315 through the high-pressure rotary joint 311. While the cleaning head rotates, the rear high-pressure water pipe remains stationary and the water path is continuously open. The high-pressure water is simultaneously sprayed onto the surface of the external thread through each water spray pipe 315. The brush assembly 314 rotates with the external thread cleaning head and cooperates with the water spray pipe 315 to clean the outer wall of the oil pipe.

[0060] The second thread cleaning unit 32 is an internal thread cleaning unit. This internal thread cleaning unit includes an internal thread cleaning head, which is a rotating nozzle with an outer diameter smaller than the inner diameter of the oil pipe, allowing it to extend into the inner hole at the end of the oil pipe. The rear end of the internal thread cleaning head is connected to a high-pressure water pipe. High-pressure water is sprayed out through the nozzle at the front end of the internal thread cleaning head to perform high-pressure rotating jet cleaning of the internal threads.

[0061] The first coarse centering unit 51 and the second coarse centering unit have the same structure, both used for coarse positioning of the tubing end face. For example... Figure 9 As shown, both coarse centering units include a centering housing 511, a moving rod 512, a baffle 513, an oil pipe cover 514, and a spring 515. The centering housing 511 is slidably mounted on the guide rail of the arc mounting base and can move as a whole along the oil pipe axis by a drive mechanism. The moving rod 512 passes through the centering housing 511 and can slide relative to it. The front end of the moving rod 512 extends out of the centering housing 511 and is fixedly connected to the oil pipe cover 514. The rear end of the moving rod 512 is connected to the baffle 513 fixed to the rear end of the centering housing 511 by the spring 515.

[0062] During operation, the coarse alignment unit moves along the guide rail towards the end face of the oil pipe. After the oil pipe cover plate 514 contacts the end face of the oil pipe, the coarse alignment unit continues to move. The moving rod 512 slides backward relative to the alignment housing 511 and compresses the spring 515. The compressed spring 515 generates a gradually increasing axial thrust, which pushes the oil pipe towards the center through the oil pipe cover plate 514. As the coarse alignment units on both sides continue to move, the compression of the spring 515 increases, and the thrust increases accordingly until the thrust on both sides reaches equilibrium, at which point the oil pipe is pushed to the center position, completing the alignment. After positioning is complete, the coarse alignment unit resets.

[0063] The first and second wire-removal units 52 have the same structure and are both used to remove the wire protector at the end of the tubing. For example... Figure 13 , Figure 14 As shown, the wire-removing assembly includes a front and rear telescopic motor 521, a telescopic transmission mechanism, a wire-removing rotary motor 522, a rotary transmission gear set, a rotary sleeve 523, and a clamping head 524. The rotary sleeve 523 is supported and mounted on the slide base by a slewing bearing, and the front end of the rotary sleeve 523 is fixedly connected to the clamping head 524.

[0064] The front and rear telescopic motors 521 are connected to the clamping head 524 via a telescopic transmission mechanism (such as a gear pair with a lead screw and nut pair, or a gear and rack mechanism, etc.) to drive the clamping head 524 to extend and retract along the oil pipe axis and to open and close the clamping head. The wire shearing removal rotary motor 522 is connected to the rotary sleeve 523 via a rotary transmission gear set to drive the rotary sleeve 523 to drive the clamping head 524 to rotate around the oil pipe axis.

[0065] During operation, the clamping head 524 first extends to the wire protector position, and the clamping part clamps the wire protector; the wire protector removal rotation motor 522 drives the clamping head 524 to rotate, and unscrews the wire protector from the end of the oil pipe; the front and rear telescopic motors 521 drive the clamping head 524 to retract in the opposite direction, and pull out the wire protector; then the clamping head 524 opens, and the wire protector is removed.

[0066] The first drying unit 54 and the second drying unit have the same structure and are both used to dry the ends of the oil pipes.

[0067] like Figure 10 , Figure 11As shown, the drying unit includes a drying servo motor 541, a hot air blower 542, a gear set 543, a connecting pipe, and a nozzle 544. The hot air blower 542 is connected to the nozzle 544 via the connecting pipe, and is used to generate hot air and deliver it to the nozzle 544. The nozzle 544 is positioned facing the end of the oil pipe, and is used to spray hot air onto the end face or inner wall of the oil pipe. The drying servo motor 541 is driven by the gear set 543 to drive the nozzle 544 to rotate around the end face or inner wall of the oil pipe. During operation, the hot air blower 542 generates hot air, which is delivered to the nozzle 544 via the connecting pipe and sprayed out. At the same time, the drying servo motor 541 drives the nozzle 544 to rotate via the gear set 543, quickly drying the end face and inner wall of the oil pipe.

[0068] The length measuring unit has the same structure as the coarse centering unit, both including a housing that can move as a whole along the oil pipe axis, a moving rod 512, an oil pipe cover plate 514, and a spring 515, and are equipped with a position sensor. During measurement, the two length measuring units move synchronously towards the oil pipe, so that the oil pipe cover plate 514 contacts the two end faces of the oil pipe respectively; the position sensor detects the position of the oil pipe cover plate 514, and the difference in position between the two oil pipe cover plates 514 is the length of the oil pipe. The position sensor can be implemented using existing technologies such as optical grating rulers and laser displacement sensors.

[0069] The first thread detection unit 55 and the second thread detection unit are used to detect the thread status at the end of the tubing. They are configured differently: one is a CCD camera 551, which is set on the skid-mounted structure corresponding to the male thread end of the tubing and is used to acquire images of the male thread end; the other is a laser detection device, which is set on the skid-mounted structure corresponding to the female thread end of the tubing and is used to perform laser measurement on the female thread end.

[0070] Each thread detection unit is equipped with a clamping and rotating mechanism 550, which is set on the corresponding skid-mounted structure to clamp the end of the oil pipe and drive the oil pipe to rotate.

[0071] A linear guide rail 555 is fixedly mounted on the skid-mounted structure. A clamping and rotating mechanism 550 is slidably mounted on the linear guide rail 555 and includes a forward / reverse motor 553, a forward / reverse lead screw 554, a clamping opening / closing motor 556, a clamping opening / closing lead screw 557, a rotary motor 558, a gear transmission pair 559, and two grippers 552. Each gripper 552 is equipped with a rotating roller 560. Figure 21 As shown.

[0072] The output end of the forward / reverse motor 553 is connected to one end of the forward / reverse lead screw 554, and the nut of the forward / reverse lead screw 554 is fixedly connected to the slide of the clamping and rotating mechanism 550. The forward / reverse motor 553 drives the forward / reverse lead screw 554 to rotate, which in turn drives the entire clamping and rotating mechanism 550 to move back and forth along the linear guide rail 555, so that the gripper 552 moves to the threaded position at the end of the oil pipe.

[0073] The output end of the clamping motor 556 is connected to the clamping screw 557. The clamping screw 557 is a bidirectional screw with both positive and negative threads. The two jaws 552 are threaded to both ends of the clamping screw 557 via screw nuts. The clamping motor 556 drives the clamping screw 557 to rotate, causing the two jaws 552 to move synchronously towards or away from each other, thus clamping or releasing the oil pipe. The rotating rollers 560 mounted on the jaws 552 open and close synchronously with the jaws 552.

[0074] The output end of the rotary motor 558 is connected to the rotary roller 560 via a gear transmission pair 559. When the gripper 552 clamps the oil pipe, the rotary motor 558 drives the rotary roller 560 to rotate via the gear transmission pair 559, and the oil pipe rotates as a whole by the friction between the rotary roller 560 and the outer wall of the oil pipe.

[0075] The lens of the CCD camera 551 (or the laser emitter of the laser detection device) is directed towards the threaded end of the oil pipe. During operation, the clamping and rotating mechanism 550 clamps the oil pipe and rotates it. The CCD camera 551 captures an image of the male threaded end, and the laser detection device performs laser measurement on the female threaded end. The data is simultaneously transmitted to the image processing system. The system uses an image recognition algorithm to determine whether there are impurities on the thread surface, whether the threads are damaged, etc., and combines the laser measurement data to comprehensively determine whether the thread is qualified.

[0076] The first coding unit 56 and the second coding unit have the same structure and are both used to print markings on the surface of the oil pipe. For example... Figure 12 As shown, the marking unit includes a marking servo motor 561, a marking guide rail 562, a marking machine 563, and a lead screw 564. The guide rail is fixedly mounted on a corresponding arc-shaped mounting base, and the marking machine 563 is slidably mounted on the marking guide rail 562. The marking servo motor 561 is connected to the marking machine 563 via the lead screw 564. During operation, the marking servo motor 561 drives the lead screw 564 to rotate, and the lead screw 564 converts the rotational motion into linear motion through the lead screw nut, driving the marking machine 563 to reciprocate along the marking guide rail 562, marking information such as serial number and well entry date on the tubing surface.

[0077] Example 2 This embodiment provides a ground-based integrated single-root treatment method, which is based on the ground-based integrated single-root treatment device described in Embodiment 1. The specific workflow is as follows: S1. Leveling and Alignment: The skid-mounted drive motor 616 drives the skid-mounted drive gear to mesh with the bottom rack 614, which in turn moves the skid-mounted mounting base 615 along the bottom guide rail 612, so that the skid-mounted structures on both sides are moved to a position that is compatible with the length of the oil pipe; the bottom lifting jack 617, in conjunction with the angle sensor, performs overall leveling of the bottom frame 611. S2, Loading: The two oil pipe support frames 717 on the loading side of the two skid-mounted structures are moved to the pipe picking position by the corresponding horizontal push motor 711 and vertical push motor 719 along the corresponding horizontal transport guide rail and vertical transport guide rail 715, respectively, to lift the oil pipe; then the horizontal push motor 711 drives in the opposite direction to move the oil pipe to the transport clamping assembly 42 of the rotary transport assembly 4; the vertical push motor 719 drives the oil pipe support seat 716 to descend and place the oil pipe between the two clamping blocks 421; the clamping drive motor 424 drives the clamping screw 425 to rotate through the clamping gear set 426. Because the threads at both ends of the clamping screw 425 rotate in opposite directions, the two clamping blocks 421 move towards each other under the guidance of the clamping block guide rail 423 to clamp the end of the oil pipe.

[0078] S3. Coarse Alignment Station: The transport turntable 41 rotates around its own axis, delivering the oil pipe to the coarse alignment unit station. The first and second coarse alignment units slide synchronously until they are aligned with the end faces of the oil pipe. The alignment housing 511 moves along the guide rail towards the end face of the oil pipe. After the oil pipe cover plate 514 contacts the end face of the oil pipe, the coarse alignment unit continues to move. The moving rod 512 slides backward relative to the alignment housing 511 and compresses the spring 515. The spring force keeps the oil pipe cover plate 514 in flexible contact with the end face of the oil pipe, ensuring that the end face of the oil pipe reaches the preset positioning reference. After positioning is completed, the coarse alignment unit resets.

[0079] S4, Wire Removal Station: The transport turntable 41 delivers the oil pipe to the wire removal unit station. The first wire removal unit 52 and the second wire removal unit slide synchronously until they are aligned with the end faces of the oil pipe. The clamping head 524 extends and clamps the wire. The wire removal rotary motor 522 drives the clamping head 524 to rotate, removing the wire from the end of the oil pipe. After completion, it is reset.

[0080] S5. Diameter Cleaning Station: The transport turntable 41 delivers the oil pipe to the diameter cleaning unit station. The diameter pushing end and diameter receiving end slide to align with the two ends of the oil pipe. The servo motor 2131 of the diameter pushing end drives the travel wheel set 2133 to rotate via the torque clutch 2132, synchronous shaft 2134, and bevel gear set. The travel wheel set 2133 clamps the hose and drives the hose forward. The hose drives the rotating nozzle 214 and the diameter gauge 216 to pass through one end of the oil pipe. At the same time, the pump starts, and high-pressure water is delivered to the rotating nozzle 214 through the hose. The water pressure drives the rotating nozzle 214 to rotate autonomously, simultaneously flushing the inner wall of the oil pipe as the diameter gauge 216 moves. The diameter gauge 216 moves completely to the other end of the oil pipe and is received by the gauge receiving mechanism 221. The sensor detects the diameter gauge 216, and the system determines that the diameter detection is complete. Then, the travel wheel assembly 2133 rotates in reverse, and the hose drives the rotating nozzle 214 to retract, performing a secondary high-pressure cleaning of the inner wall of the oil pipe. After completion, the bore cleaning unit is reset.

[0081] S6, Thread Cleaning Station: The transport turntable 41 delivers the oil pipe to the thread cleaning unit station. The external thread cleaning unit and the internal thread cleaning unit slide to align with the two ends of the oil pipe. The external thread cleaning unit uses a combination of brush and high-pressure water to clean the external threads, while the internal thread cleaning unit uses high-pressure water to rotate and spray clean the internal threads. After completion, they are reset.

[0082] S7. Length Measurement Station: The transport turntable 41 delivers the oil pipe to the length measurement unit station. The two length measurement units on both sides slide synchronously until they are aligned with the end faces of the oil pipe, and the oil pipe cover plates 514 contact the end faces of the oil pipe respectively. The position sensor detects the position of the oil pipe cover plates 514 on both sides, and the difference between the positions of the two sides is the length of the oil pipe. After completion, reset.

[0083] S8. Drying Station: The transport turntable 41 delivers the oil pipe to the drying unit station, and the drying unit slides until it is aligned with the end face of the oil pipe. The hot air blower 542 generates hot air, and the air nozzle 544 rotates to blow the hot air evenly onto the end face and inner wall of the oil pipe for drying. After completion, it is reset.

[0084] S9. Thread Inspection Station: The transport turntable 41 delivers the oil pipe to the thread inspection unit station. The two clamping and rotating mechanisms 550 move forward along the linear guide rail 555, and the grippers 552 move to the threaded end of the oil pipe. The clamping opening and closing motor 556 drives the clamping opening and closing screw 557 to rotate, causing the two grippers 552 to move synchronously towards each other and clamp the end of the oil pipe. The rotating motor 558 drives the rotating roller 560 to rotate, causing the oil pipe to rotate. The CCD camera 551 and the laser detection device inspect the threaded end and output the inspection results. After the inspection is completed, the grippers 552 are released, and the clamping and rotating mechanisms 550 retract and reset.

[0085] S10, Marking Station: The transport turntable 41 delivers the oil pipe to the marking unit station, and the marking machine 563 moves along the marking guide rail 562 to print marks on the surface of the oil pipe. After completion, it resets.

[0086] S11. Unloading: After all pre-processing is completed, the handling clamping assembly 42 is released. The two oil pipe support frames 717 on the unloading side of the two skid-mounted structures are driven by the corresponding horizontal push motor 711 and vertical push motor 719, respectively, to lift the oil pipes from both ends and remove them from the clamping position of the rotating handling assembly 4, and transfer them to the lifting and hoisting device or the next process.

[0087] In this embodiment, the working modes of the rotary conveying assembly 4 include: the conveying turntable 41 can clamp only one oil pipe, and after the oil pipe has completed all pre-processing, it clamps the next oil pipe; the conveying turntable 41 can also clamp multiple oil pipes simultaneously, and for each rotation of a station angle, the oil pipes at each station move forward one station synchronously, with multiple oil pipes being processed in parallel at different stations. When multiple oil pipes are processed in parallel, the oil pipe at the last station completes all pre-processing and moves out, while the first station becomes vacant, and the next oil pipe enters the first station, forming a continuous assembly line operation.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
