It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0055] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0056] like Figures 1 to 5As shown, this embodiment provides a non-destructive testing device for drill pipes, including a support platform 1, a support structure 2, a detection structure 3, and a flipping drive structure 4. The support structure 2 includes multiple support components 21 spaced apart along a first horizontal direction. Each support component 21 includes a bracket 211 and two support rollers 212. A limiting groove is formed on the bracket 211. The two support rollers 212 are symmetrically arranged around the center of the bracket 211, and each support roller 212 is rotatably mounted on the bracket 211. The drill pipe 100 is placed in the limiting groove and abuts against the support roller 212. The detection structure 3 includes a movable frame 31, an ultrasonic detector 32, and a probe 33. The movable frame 31 is movably mounted on the support platform 1 along the first horizontal direction. The ultrasonic detector 32 is mounted on the movable frame 31. The probe 33 is connected to the ultrasonic detector 32 and movably mounted on the movable frame 31 along the vertical direction. The probe 33 is configured to abut against the drill pipe 100 for flaw detection. By moving the movable frame 31 along the first horizontal direction, the probe 33 can be moved, thereby realizing flaw detection along the extension direction of the drill pipe 100.
[0057] The flipping drive structure 4 includes a first drive mechanism 41 and a friction wheel 42. The first drive mechanism 41 is mounted on the support platform 1, and the friction wheel 42 is rotatably mounted on the support platform 1 and located at the output end of the first drive mechanism 41. The friction wheel 42 abuts against the drill pipe 100. Driven by the first drive mechanism 41, the friction wheel 42 can rotate around its own axis, thereby driving the drill pipe 100 to rotate, realizing the automated flipping of the drill pipe 100 without manual operation, which is more convenient and faster and helps to improve the efficiency of flaw detection of the drill pipe 100.
[0058] Specifically, the number of support components 21 can be set as needed according to the length of the drill pipe 100, and no specific limit is made here.
[0059] For example, in this embodiment, the bracket 211 is U-shaped and the limiting groove opened on the bracket 211 is also U-shaped. The U-shaped setting is beneficial to improving the stability of the drill rod 100 placement.
[0060] For example, the first drive mechanism 41 is a motor commonly used in the art. The ultrasonic detector 32 and the probe 33 are existing devices that have been disclosed in the prior art, and their specific structures and principles are referred to in the prior art, and will not be described again here.
[0061] Optionally, the surface of the friction wheel 42 is provided with a flexible element, and the drill rod 100 abuts against the flexible element, which can increase the friction between the drill rod 100 and the friction wheel 42, ensuring the smooth rotation of the drill rod 100; at the same time, it can also effectively prevent the drill rod 100 from wearing during the rotation process.
[0062] Optionally, the drill pipe non-destructive testing device also includes a transmission structure 5, such as... Figure 2As shown, the transmission structure 5 includes a rack 51, a second drive mechanism 52, and a gear 53. The rack 51 extends along a first horizontal direction and is mounted on the support platform 1. The rack 51 and the support structure 2 are spaced apart along a second horizontal direction, with the first horizontal direction perpendicular to the second horizontal direction. The second drive mechanism 52 is mounted on the movable frame 31, and the gear 53 is located at the output end of the second drive mechanism 52 and meshes with the rack 51. Driven by the second drive mechanism 52, the gear 53 rotates. Combined with the meshing relationship between the gear 53 and the rack 51, the movable frame 31 can be moved along the rack 51, that is, the movable frame 31 can be moved along the first horizontal direction to realize the automated movement of the probe 33 along the outer wall of the drill rod 100. This eliminates the need for manual operation of the probe 33, making it convenient, fast, time-saving, and labor-saving.
[0063] Specifically, the second drive mechanism 52 is a motor commonly used in the art. The fixed end of the second drive mechanism 52 is set on the movable frame 31, and the output end is provided with an output shaft. The output shaft is rotatably mounted on the movable frame 31. The end of the output shaft away from the second drive mechanism 52 extends to the bottom side of the movable frame 31 and is provided with a gear 53.
[0064] Furthermore, continue to refer to Figure 2 The transmission structure 5 also includes a guide assembly 54, which includes a guide member 541 and a pulley 542. The guide member 541 is mounted on the support platform 1 and has a guide groove 5410 extending along a first horizontal direction. A rack 51 is disposed within the guide groove 5410. A limiting groove 5411 is provided on the outer wall of the guide member 541, which also extends along the first horizontal direction. The pulley 542 is disposed on the bottom side of the movable frame 31 and is slidably disposed within the limiting groove 5411. When the movable frame 31 slides along the rack 51, the pulley 542 moves synchronously along the limiting groove 5411 to provide guidance for the sliding of the movable frame 31 and ensure the accuracy of the sliding direction of the movable frame 31. Specifically, in this embodiment, the cross-sectional shape of the guide member 541 is U-shaped.
[0065] Furthermore, the guide member 541 is provided with a limiting groove 5411 on each of its two outer walls along the second horizontal direction, and the bottom side of the movable frame 31 is provided with two pulleys 542, which are slidably disposed in the two limiting grooves 5411 in a one-to-one correspondence, so as to further improve the stability and directional accuracy of the sliding of the movable frame 31.
[0066] Optionally, the detection structure 3 also includes a vertical adjustment component 34, such as... Figure 3As shown, the vertical adjustment assembly 34 includes a stand 341, a third drive mechanism 342, and a fixed base 343. The stand 341 is mounted on the movable frame 31, the third drive mechanism 342 is mounted on the stand 341, and the fixed base 343 is located at the output end of the third drive mechanism 342. The probe 33 is located on the side of the fixed base 343 away from the third drive mechanism 342. Under the drive of the third drive mechanism 342, the fixed base 343 can move vertically to ensure that the probe 33 is in contact with the drill pipe 100, thereby ensuring the smooth progress of flaw detection. Furthermore, this device is applicable to flaw detection of drill pipes 100 of different sizes, thus improving its applicability.
[0067] Specifically, in this embodiment, the support frame 341 includes a vertical rod and a horizontal rod. The vertical rod extends in the vertical direction and is disposed on the movable frame 31, and the horizontal rod extends in the second horizontal direction and is disposed on the vertical rod.
[0068] For example, the third drive mechanism 342 is an electric actuator commonly used in the art.
[0069] Furthermore, the vertical adjustment assembly 34 also includes multiple slide rods 344, which extend vertically. One end of each slide rod 344 slides through the support frame 341, and the other end is connected to the fixed base 343. When the fixed base 343 moves vertically under the drive of the third drive mechanism 342, it simultaneously drives the slide rods 344 to move vertically, thus guiding the movement of the fixed base 343 and preventing it from rotating around the vertical direction.
[0070] Specifically, in this embodiment, two slide rods 344 are provided, and the two slide rods 344 are spaced apart on both sides of the third drive mechanism 342; in other embodiments, the number of slide rods 344 can be set as needed, and no specific limitation is made here.
[0071] Furthermore, each slide rod 344 is provided with an anti-slip part (not shown in the figure) at the end away from the fixing base 343 to prevent the slide rod 344 from slipping off the stand 341. Specifically, the anti-slip part is a fixing block provided at the end of the slide rod 344. The fixing block can be of any shape, as long as the size of the fixing block is larger than the diameter of the slide rod 344.
[0072] Optionally, the vertical adjustment assembly 34 also includes a pressure sensor 345, a slider 346, a controller, and an elastic element 347. For example... Figure 4As shown, the mounting base 343 has a mounting groove on the side facing the probe 33. The pressure sensor 345 is set at the bottom of the mounting groove. The slider 346 is slidably set in the mounting groove in the vertical direction. The probe 33 is set on the side of the slider 346 away from the mounting groove. The controller (not shown in the figure) is connected to the pressure sensor 345 and to the third drive mechanism 342. The controller can control the start and stop of the third drive mechanism 342. The elastic element 347 is connected between the slider 346 and the bottom of the mounting groove. After the probe 33 moves above the drill rod 100, the third drive mechanism 342 drives the fixed base 343 and the probe 33 to move vertically, bringing the probe 33 into contact with the drill rod 100. The third drive mechanism 342 continues to drive the fixed base 343 and the probe 33 to move, causing the slider 346 to slide towards the bottom of the mounting groove, while simultaneously pressing the elastic element 347. When the slider 346 contacts the pressure sensor 345, the pressure sensor 345 can detect the pressure value. After receiving the monitoring value from the pressure sensor 345, the controller stops the drive of the third drive mechanism 342. Under the elastic force of the elastic element 347, the probe 33 can stably abut against the drill rod 100, ensuring a tight fit between the probe 33 and the outer wall of the drill rod 100, thereby improving the reliability of the detection results.
[0073] Specifically, the pressure sensor 345 and the controller are existing devices that have been disclosed in the prior art. Their specific structure and principle are the same as those in the prior art and will not be described in detail here.
[0074] More specifically, in this embodiment, the slider 346 has a contact block corresponding to the pressure sensor 345 on the side facing the bottom of the mounting groove; in other embodiments, the contact block may not be provided.
[0075] For example, in this embodiment, the elastic element 347 is a spring, and two elastic elements 347 are spaced apart; in other embodiments, the elastic element 347 may also be elastic rubber or the like, and the number of elastic elements 347 may be set as needed.
[0076] Optionally, the tilting drive structure 4 also includes a reducer 43, see reference. Figure 5 The reducer 43 is located between the first drive mechanism 41 and the friction wheel 42. According to the inverse relationship between torque and speed, under the condition of constant power, the reducer 43 can reduce the speed while proportionally increasing the torque to ensure that the friction wheel 42 can smoothly rotate the drill rod 100.
[0077] Specifically, the reducer 43 is an existing device that has been disclosed in the prior art. Its specific structure and principle are the same as those in the prior art and will not be described in detail here.
[0078] Optionally, a support 11 is provided on the support platform 1, and the friction wheel 42 is rotatably mounted on the support 11 to improve the stability of the friction wheel 42. Specifically, in this embodiment, the support platform 1 includes a support plate and a support frame. The support plate is mounted on the support frame, and an avoidance hole 12 is provided on the support plate. A fixed plate is provided on the bottom side of the support plate, and the support 11 is mounted on the fixed plate and extends into the avoidance hole 12 to ensure that the friction wheel 42 can abut against the outer wall of the drill rod 100. The reducer 43 and the third drive mechanism 342 are also mounted on the fixed plate, effectively avoiding interference between the flipping drive structure 4 and the drill rod 100, and making the spatial layout more reasonable.
[0079] Specifically, in this embodiment, only one flipping drive structure 4 is provided; in other embodiments, multiple flipping drive structures 4 may be provided at intervals along the extension direction of the drill rod 100 to ensure the smooth flipping of the drill rod 100.
[0080] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
