Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, in particular to a measuring device for measuring the tensile performance feedback length of a marine drilling joint after heat treatment. Background Art

[0002] The safety and efficiency of offshore drilling operations place extremely high demands on the quality of joints. Heat-treated joints must be able to withstand high pressure and complex working environments, so it is necessary to ensure that their mechanical properties meet the expected standards. Through tensile performance testing, key indicators such as the strength and ductility of the joint can be evaluated to ensure its reliability and safety in actual use. In offshore drilling operations, the precise length of the joint is a key parameter during installation and connection. Length measuring equipment can ensure that the joint meets the specified size requirements, thereby ensuring the compatibility and reliability of each joint during installation and transportation.

[0003] In the prior art, a Chinese patent document with publication number CN212674003U proposes a length measuring device for a tensile test failure specimen, in which slideways are fixed on both sides of a base plate, and a length positioning block and a width positioning block slide along the length direction of the slideway respectively. When sliding, the length positioning block and the width positioning block are parallel to the length direction and the width direction of the base respectively. The failure specimen is placed on the base plate, and the length positioning block and the width positioning block push the failure specimen to the corner of the base plate from both sides for positioning. The dimensions of each part of the failure specimen can be seen from the ruler by moving the front pointer and the rear pointer along the slideway. However, consistent with the traditional method, the traditional device There is usually a lack of synchronization in the clamping and stretching processes. For example, the process of clamping and fixing the drilling joint is not well coordinated with the stretching operation process. Usually, manual operation is required to clamp and fix the position of the drilling joint and then drive the stretching, which is time-consuming and labor-intensive. In addition, there may be a lack of real-time data collection and feedback mechanism during the stretching process, which makes it impossible for operators to obtain key tensile performance data in time, thereby affecting the accuracy and reliability of the data. Therefore, the present application discloses a length measurement device for measuring the tensile performance feedback of marine drilling joints after heat treatment to meet the coordination of self-clamping of the drill bit during tensile testing of the drilling joint and real-time and accurate data feedback.

The stretching feedback module is located above the extension plate 24. The stretching feedback module is used to measure the tensile performance of the drilling joint. The length measurement module is arranged above the positioning frame 33. The length measurement module is used to measure the length of the drilling joint after stretching. A cooling assembly is arranged on both sides of the interior of the positioning box 2. The cooling assembly is used to cool the stretched drilling joint. A door frame 20 is fixedly installed in the middle of the mounting plate 1. A second positioning wheel 21 is rotatably installed below the door frame 20. One end of the clamping assembly is fixedly connected to a wire rope 22. The other end of the wire rope 22 is fixedly connected to one end of the stretching feedback module.

[0040] Insert the heat-treated drilling joint from the position of the guide block 3 into the through hole 4 and enter the positioning box 2. After the drilling joint enters the positioning box 2, the clamping assembly clamps and positions it to ensure that the drilling joint is firmly fixed in the correct position. Start the driving assembly, and the driving assembly drives the stretching feedback module to pull the wire rope 22. The wire rope 22 is accurately positioned through the door frame 20 and the second positioning wheel 21 to keep the wire rope 22 stable during the stretching process. The driving assembly continues to pull the clamping assembly to start the stretching operation on the drilling joint. During the stretching process, the stretching feedback module detects and records the tensile performance data of the drilling joint in real time. At the same time, the length measurement module starts to work, measures the stretching length of the drilling joint, and displays the result in real time. Among them, the positioning box 2 and the guide block 3 ensure the accurate positioning of the drilling joint in the equipment, so that the subsequent clamping and stretching operations are more accurate and reduce operating errors.

[0042] The heat-treated drilling joint is inserted into the through hole 4 from the position of the guide block 3, and after entering the interior of the positioning box 2, it directly contacts the stop block 10. At this time, the stop block 10 slides along the moving rod 6 and compresses the reset spring 11, driving the clamping plate 9 to clamp the drilling joint. At this time, the driving component pulls the moving rod 6 to move, driving the first linkage rod 7 and the second linkage rod 8 to close the clamping plate 9, and continues to drive the clamping plate 9 to further clamp and fix the drilling joint. The clamping teeth 12 on the clamping plate 9 tightly grasp the drilling joint to ensure that the drilling joint is firmly clamped in the correct position. When the clamping is tightened Only then will the clamping module 5 and the drilling joint be pulled to move together to stretch the drilling joint. The advantage of this is that the drilling joint is clamped by three clamps 9 to ensure the stability and immobility of the drilling joint during the stretching process, and to avoid measurement errors caused by loosening. In addition, the moving rod 6 can flexibly adjust the position of the clamps 9 through the first linkage rod 7 and the second linkage rod 8 to adapt to drilling joints of different sizes. At the same time, a reset spring 11 is provided at the connection between the stop block 10 and the moving rod 6, so that the clamping assembly can automatically reset after being relaxed, so as to facilitate the next operation to be carried out quickly.

[0043] like Figure 2 , Figure 4 , Figure 8 , Fig. 9 As shown, the driving assembly includes a toothed plate 25 slidably mounted on the middle part above the extension plate 24, and a driving box 26 fixedly mounted on one side above the extension plate 24, a rotating rod 27 is arranged on the inner top of the driving box 26, a first gear 29 and a second gear 30 are coaxially mounted on the inner middle part of the driving box 26, a worm 28 meshing with the first gear 29 is fixedly sleeved on one side of the rotating rod 27, the second gear 30 meshes with the toothed plate 25, an adjusting wheel is fixedly connected to the other end of the rotating rod 27, and a stretching feedback module includes a stretching detector 31 fixedly mounted on one side of the toothed plate 25, a stretching detection hook 32 is arranged on the side of the stretching detector 31 away from the driving box 26, and a connecting frame 23 is fixedly connected to the side of the wire rope 22 close to the stretching detector 31, the connecting frame 23 is arranged in an inverted T shape, and the stretching detection hook 32 is connected to the connecting frame 23;

[0044] After the drilling joint is clamped, the rotating rod 27 is manually adjusted by the adjusting wheel to rotate, and the rotating rod 27 drives the worm 28 to rotate and mesh with the first gear 29, further driving the second gear 30, the second gear 30 meshes with the tooth plate 25, and the driving box 26 drives the tooth plate 25 to slide along the extension plate 24, the second gear 30 meshes with the tooth plate 25, and the driving box 26 drives the tooth plate 25 to slide along the extension plate 24.

[0045] The length measuring module includes two fixed blocks 34 fixedly mounted above the positioning frame 33 and two length measuring boxes 36, a connecting rod is fixedly mounted above the two fixed blocks 34, a third positioning wheel 35 is rotatably mounted in the middle of the connecting rod, a slide groove 47 is vertically opened in the middle of the two length measuring boxes 36, a sliding plate 37 is slidably mounted inside the two slide grooves 47, a mounting block 39 is fixedly mounted on the opposite surface of the two sliding plates 37, a positioning rod 40 is fixedly connected between the two mounting blocks 39, a fourth positioning wheel 41 is rotatably mounted in the middle of the positioning rod 40, the wire rope 22 is respectively wound around the third positioning wheel 35 and the fourth positioning wheel 41, and the wire rope 22 is wound around the top of the third positioning wheel 35, the wire rope 22 is wound around the bottom of the fourth positioning wheel 41, and the wire rope between the third positioning wheel 35 and the fourth positioning wheel 41 is arranged in an S shape.

The coefficient is calculated. During the upward movement of the sliding plate 37, the tension spring 43 is compressed by squeezing the deformable metal extrusion sheet 42. When the positioning of the drilling joint is released, the sliding plate 37 can be pushed to reset and wait for the next operation. The sliding plate 37 drives the scale pointer 38 to move along the scale 44, so that the operator can intuitively observe the change of the stretching length, which is convenient for accurately calculating the stretching coefficient. The combination of the extrusion sheet 42 and the tension spring 43 provides a stable elastic feedback, so that the sliding plate 37 can rise smoothly during the stretching process, ensuring the stability and reliability of the measurement results.
