Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and specifically to an automatic feeding system for a torque force testing device for drilling joints. Background Art

[0002] Offshore drilling operations are completed by offshore drilling platforms or drilling ships. By breaking rocks with a drill bit, a "channel" is formed between the sea surface and the formation, allowing oil to reach the sea surface through this "channel" to complete the exploitation of subsea oil reserves. During the oil drilling process, the top drive (abbreviation for the top drive device) plays an important role and is one of the main power devices in drilling operations. The top drive will drive the drill pipe to rotate, and under a certain drilling pressure, the drill bit will drill through the formation and drill downward. Breaking rocks requires a very large torque. Insufficient torque will directly lead to the inability to drill, delaying the operation time, increasing the operation cost and operation risk. During the formal drilling process, the torque of the top drive cannot be tested. Therefore, before drilling, it is necessary to test the torque that the top drive can provide to check whether it can meet the design standards to ensure the smooth implementation of the drilling operation.

[0003] Traditional torque force testing devices for drilling joints usually rely on manual operation to control the feeding process. This method requires the intervention of operators and is easily affected by the skill level and fatigue degree of the operators, which may lead to errors or inconsistencies in the testing process. Therefore, this application discloses an automatic feeding system for a torque force testing device for drilling joints to meet the testing accuracy during the torque force testing of drilling joints and reduce the influence of manual operation on the test results.

[0016] Compared with the prior art, the present invention provides an automatic feeding system for a torque force testing device for a drilling joint, and has the following beneficial effects:

[0017] 1. The automatic feeding system of the torque force testing device for the drilling joint places the drilling joint to be tested on the first transport plate. By setting the first transport plate to be inclined to one side, the drilling joint to be tested is closely attached to the limit block. At the same time, the output end of the pushing cylinder pushes the driving plate to move. When the driving plate moves, it drives the first synchronous plate and the second synchronous plate to have a relative displacement, so that the lifting plate slides in the through groove on the conveying plate driven by the lifting block. At the same time, both ends of the lifting plate are fixedly connected with limit bumps adapted to the limit grooves, and the bending degree of the lifting plate is the same as that of the conveying plate, so that the lifting plate is closely attached to the conveying plate, and then the drilling joint to be tested can be in contact with the conveying plate. At the same time, when the lifting block moves, it can drive the fixed table to move, so that the connecting arm deflects around the axis of the fixed rod, and then the limit block rotatably connected to the connecting arm moves on the first transport plate. When the limit block completes a single up and down movement on the first transport plate, the drilling joint to be tested closely attached to the limit block on the first transport plate can be individually fed into the conveying plate. Then, under the push of the output end of the pushing cylinder, the pushing plate contacts the drilling joint to be tested, thus completing the detection of the drilling joint to be tested, effectively improving the detection efficiency of the drilling joint, reducing the steps of manual participation in the detection, avoiding the generation of manual errors, and then improving the detection accuracy.

[0018] 2. The automatic feeding system of the torque force testing device for the drilling joint enables the drilling joint to be tested to slide on the conveying plate, so that one end of the drilling joint to be tested contacts the moving plate, and then the fixed arm enters the interior of the drilling joint to be tested. At the same time, when the drilling joint to be tested continuously contacts and squeezes the moving plate, it can cause a relative displacement between the driving rod and the moving plate. While the moving plate moves to one side, the driving rod remains relatively fixed, thus realizing the separation between the moving plate and the moving ring. When the moving plate moves, it can drive the rotating seat to move synchronously, so that the rotating seat drives the fixed arm to deflect around the axis of the deflecting plate. Since the fixed arm is an arc-shaped structure deflecting outward, the fixed arm is closely attached to the inner wall of the drilling joint to be tested, thus realizing the fixing effect on drilling joints of different sizes and effectively improving the applicable range.

[0019] 3. The automatic feeding system of the torque force testing device for the drilling joint drives the connecting plate to move synchronously through the movement of the fixing component. When the connecting plate moves, it can drive the lifting rod to move within the guiding slope. Since the guiding slope is a triangular shape inclined to one side, the height of the lifting rod within the guiding slope gradually decreases. At the same time, when the height of the lifting rod decreases, the synchronous arm deflects around the axis of the connecting rod driven by the rotating rod. Meanwhile, when the synchronous arm deflects, it can drive the connecting plate to deflect simultaneously, thus completing the commutation of the fixing component. At the same time, the drilling joint can enter the drill pipe power tong for detection by sliding the fixing rod on the connecting arm. Compared with the traditional detection method that requires manual handling of the drilling joint to achieve the detection of the drilling joint, it reduces the manual participation and improves the detection accuracy.

[0020] 4. After the detection of the drilling joint by the automatic feeding system of the torque force testing device for the drilling joint, the elastic force of the return spring drives the lifting rod to reset along the guiding slope under the guidance of the guiding rod, thereby realizing the repeated detection of the drilling joint, effectively improving the detection speed and further enhancing the detection efficiency.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an automatic feeding system for a torque force testing device for drilling joints.

[0035] In a typical embodiment of the present application, as Figures 1-11As shown in the figure, the automatic feeding system of the torque force testing device for drilling joints includes a first support rod 1. At the top of the first support rod 1, a support platform 2 is fixedly connected. At the top of the support platform 2, a drill pipe power tong 3 is fixedly connected. On one side of the drill pipe power tong 3, a driving motor 4 is fixedly connected. The driving motor 4 is used to drive the drill pipe power tong 3 to operate. On one side of the support platform 2, a plurality of groups of second support rods 5 are fixedly connected. At the top of the second support rods 5, a first transport plate 6 and a second transport plate 7 are fixedly connected. A conveying plate 10 is fixedly connected between the first transport plate 6 and the second transport plate 7. Both the first transport plate 6 and the second transport plate 7 are inclined to one side; A limiting plate 8 is fixedly connected to one side of the conveying plate 10. A pushing cylinder 9 is fixedly connected to the limiting plate 8. One end of the pushing cylinder 9 is fixedly connected with a control component. At the bottom of the drill pipe power tong 3, there is a fixed platform 18. The fixed platform 18 and the first support rod 1 are on the same horizontal plane. A fixing component is arranged on the fixed platform 18; One end of the fixing component is fixedly connected with a commutation component; The control component is used to control the quantity of the drilling joints to be tested; The fixing component is used to fix the drilling joints to be tested; The commutation component is used to reverse the drilling joints to be tested so that they enter the drill pipe power tong 3 for detection; By placing the drilling joints to be tested on the conveying plate 10, since both the first transport plate 6 and the second transport plate 7 are inclined to one side, the conveying plate 10 is inclined, which is beneficial to the smooth transportation of the joints. The pushing cylinder 9 is driven by the control component to push the joints to move forward along the conveying plate 10. During this process, the control component is responsible for controlling the quantity of the drilling joints to be tested to ensure that each joint enters the test area in sequence. The commutation component operates to correctly position it into the drill pipe power tong 3. The driving motor 4 activates the drill pipe power tong 3 to conduct torque force testing on the joints. After the testing is completed, the system automatically releases and is ready to receive the next joint, improving the testing efficiency and accuracy, while reducing the intervention of operators, being applicable to various drilling environments and joint types, and improving the applicable range.

[0036] As a preferred implementation manner in this embodiment, refer to the attached Figures 1-6, the control component includes a drive plate 15 fixedly connected to the output end of the push cylinder 9. One side of the drive plate 15 is fixedly connected with a first synchronizing rod 17. The first synchronizing rod 17 communicates with multiple drive plates 15. The drive plate 15 is fixedly connected with a second synchronizing plate 16. The second synchronizing plate 16 is a trapezoid inclined to one side. The conveying plate 10 is a semi-circular structure. Multiple through slots are provided on the conveying plate 10. A lifting block 13 is slidably connected in the through slot. The top of the lifting block 13 is fixedly connected with a lifting plate 12. The lifting plate 12 has the same curvature as the conveying plate 10. One side of the lifting block 13 is fixedly connected with a first synchronizing plate 14. The first synchronizing plate 14 is a trapezoid inclined to one side. The first synchronizing plate 14 is adapted to the second synchronizing plate 16. One end of the lifting block 13 is fixedly connected with a connecting rod. The connecting rod is a telescopic structure. One end of the connecting rod is rotatably connected with a connecting arm 41. One end of the connecting arm 41 is rotatably connected with a fixed rod 42. One end of the fixed rod 42 is fixedly connected inside one side of the limiting plate 8. One end of the connecting arm 41 is rotatably connected with a limiting block 43. A slot adapted to the limiting block 43 is provided on the first conveying plate 6. One side of the limiting block 43 is fixedly connected with a cooperative rod 44. The cooperative rod 44 is used to connect adjacent limiting blocks 43. The output end of the push cylinder 9 is fixedly connected with a push plate 23. The push plate 23 is slidably connected on the conveying plate 10. The drive plate 15 is located at one end of the push plate 23. By placing the drill joint to be detected on the first conveying plate 6, due to the inclined setting of the first conveying plate 6 to one side, the drill joint to be detected is closely attached to the limiting block 43. At the same time, the output end of the push cylinder 9 pushes the drive plate 15 to move. When the drive plate 15 moves, relative displacement occurs between the first synchronizing plate 14 and the second synchronizing plate 16, thereby causing the lifting plate 12 to slide in the through slot on the conveying plate 10 driven by the lifting block 13. At the same time, both ends of the lifting plate 12 are fixedly connected with limiting protrusions adapted to the limiting slots 11, and the lifting plate 12 has the same curvature as the conveying plate 10, so that the lifting plate 12 is closely attached to the conveying plate 10, and further enables the drill joint to be detected to be in contact with the conveying plate 10. At the same time, when the lifting block 13 moves, it can drive the connecting rod to move, thereby causing the connecting arm 41 to deflect around the axis of the connecting rod, and further causing the limiting block 43 rotatably connected to the connecting arm 41 to move on the first conveying plate 6. When the limiting block 43 completes a vertical movement on the first conveying plate 6, the drill joint to be detected closely attached to the limiting block 43 on the first conveying plate 6 can be singly fed into the conveying plate 10. Then, under the push of the output end of the push cylinder 9, the push plate 23 contacts the drill joint to be detected, and the drill joint to be detected is pushed into the drill pipe power tongs 3 for detection, effectively improving the detection efficiency of the drill joint, reducing the steps of manual participation in detection, avoiding the generation of manual errors, and further improving the detection accuracy.

[0037] As a preferred implementation manner in this embodiment, referring to the attached Figure 5 , Figures 7-11 , the fixing component includes a telescopic sleeve 29 fixedly connected to one side of the connecting plate 28. The telescopic sleeve 29 is a telescopic structure. One end of the telescopic sleeve 29 is fixedly connected to a moving plate 30. A driving rod 31 passes through the moving plate 30. One end of the driving rod 31 is fixedly connected to the connecting plate 28. A telescopic spring is fixedly sleeved on the driving rod 31. One end of the telescopic spring is fixedly connected to one side of the connecting plate 28, and the other end of the telescopic spring is fixedly connected to one side of the moving plate 30. One end of the driving rod 31 is fixedly connected to a moving ring 32. A plurality of deflection plates 33 are rotatably connected to the moving ring 32. A fixing arm 34 is rotatably connected to the deflection plate 33. The fixing arm 34 is an arc-shaped structure that deflects outward. The outer side of the fixing arm 34 preferably contacts the inner wall of the drilling joint. One end of the fixing arm 34 is rotatably connected to a rotating seat 35. The rotating seat 35 is fixedly connected to one side of the moving plate 30; One side of the bottom of the lifting rod 22 is fixedly connected to a guiding rod 36. One end of the guiding rod 36 is fixedly connected to the inner wall of one side of the support plate 40. The guiding rod 36 is a telescopic structure. A return spring 37 is fixedly sleeved on the guiding rod 36. One end of the return spring 37 is fixedly connected to one side of the lifting rod 22, and the other end of the return spring 37 is fixedly connected to the inner wall of the support plate 40; By sliding the drilling joint to be detected on the conveying plate 10, one end of the drilling joint to be detected contacts the moving plate 30, so that the fixing arm 34 enters the interior of the drilling joint to be detected. At the same time, when the drilling joint to be detected continuously contacts and presses the moving plate 30, relative displacement can occur between the driving rod 31 and the moving plate 30. While the moving plate 30 moves to one side, the driving rod 31 remains relatively fixed, thereby realizing the separation between the moving plate 30 and the moving ring 32. When the moving plate 30 moves, it can drive the rotating seat 35 to move synchronously, and then the rotating seat 35 drives the fixing arm 34 to deflect around the axis of the deflection plate 33. Since the fixing arm 34 is an arc-shaped structure that deflects outward, the fixing arm 34 is closely attached to the inner wall of the drilling joint to be detected, thereby realizing the fixing effect on drilling joints of different sizes and effectively improving the applicable range.

[0038] As a preferred implementation manner in this embodiment, referring to the attached Figures 7-10, the commutation assembly includes a support plate 40 fixedly connected to the bottom of the fixed platform 18. A group of guiding slopes 38 are fixedly connected to the support plate 40. The guiding slopes 38 are triangular and inclined to one side. A guiding groove 39 is formed in the guiding slopes 38. A lifting rod 22 is slidably connected in the guiding groove 39. The lifting rod 22 penetrates through the bearing plate 21. The bearing plate 21 is fixedly connected to the sliding disk 20. The sliding disk 20 is slidably connected to the sliding track 19. The sliding track 19 is fixedly connected to the fixed platform 18. A group of rotating rods 24 are fixedly connected to the lifting rod 22. A synchronous arm 25 is rotatably sleeved on the rotating rod 24. A group of fixing plates 27 are fixedly connected to the bearing plate 21. A deflecting rod 26 is fixedly connected to the fixing plate 27. The synchronous arm 25 is rotatably connected to the deflecting rod 26. One end of the synchronous arm 25 is fixedly connected to a connecting plate 28; through the movement of the fixing assembly, the connecting plate 28 is driven to move synchronously. When the connecting plate 28 moves, the lifting rod 22 can be driven to move in the guiding slope 38. Since the guiding slope 38 is triangular and inclined to one side, the height of the lifting rod 22 in the guiding slope 38 gradually decreases. At the same time, when the height of the lifting rod 22 decreases, the synchronous arm 25 is driven by the rotating rod 24 to deflect around the axis of the deflecting rod 26. At the same time, when the synchronous arm 25 deflects, the connecting plate 28 can be driven to deflect simultaneously, thereby completing the commutation of the fixing assembly. At the same time, by sliding the sliding disk 20 on the sliding track 19, the drilling joint can enter the drill pipe power tong 3 for detection. Compared with the traditional detection method, it is necessary to manually carry the drilling joint, thereby realizing the detection of the drilling joint, reducing the manual participation, and improving the detection accuracy; at the same time, when the detection of the drilling joint is completed, the elastic force of the return spring 37 drives the lifting rod 22 to reset along the guiding slope 38 under the guidance of the guiding rod 36, so as to realize the repeated detection of the drilling joint, effectively improving the detection speed and further improving the detection efficiency.
