[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0029] The core of the utility model provides a kind of petroleum drilling tool thread automatic judge repair device, realize the automatic transmission, scanning and judge repair of drilling tool thread, improve the thread maintenance quality and efficiency, and facilitate the automatic record of thread quality inspection data.

[0030] The utility model provides petroleum drilling tool thread automatic judge repair device, including:

[0031] Drilling tool transmission mechanism is used to convey the drilling tool 01 to be detected along the axial direction and drive the drilling tool 01 to be detected to rotate;

[0032] Drilling tool detection mechanism includes laser detection head 21 for image acquisition to the external thread and shoulder surface of the drilling tool 01 to be detected and horizontal adjusting assembly for adjusting the horizontal position of laser detection head 21, so that it is aligned with the drilling tool 01 to be detected;

[0033] Control device 4, drilling tool transmission mechanism and drilling tool detection mechanism are signal connected with control device 4.

[0034] Among them, drilling tool transmission mechanism is used to convey the drilling tool 01 to be detected along the axial direction, and drive the drilling tool 01 to be detected to rotate, so as to cooperate with laser detection head 21 to carry out 360 ° image acquisition to drilling tool thread and shoulder surface, and drilling tool transmission mechanism is usually set as conveyor belt assembly, conveying roller assembly and the like.

[0035] Drilling tool detection mechanism is used to scan the thread of the drilling tool 01 to be detected, and obtain corresponding graphic information, so that control device 4 analyzes and processes the above-mentioned image information, obtains the thread quality inspection condition information of the drilling tool 01 to be detected, such as the position and length of thread and shoulder surface damage;

[0036] In order to ensure that laser detection head 21 completely collects image information of drilling tool thread and shoulder surface, it is necessary to align laser detection head 21 and the drilling tool 01 to be detected through horizontal adjusting assembly, so that the center of laser detection head 21 is arranged opposite to the axis of the drilling tool 01 to be detected.

[0037] Control device 4 is built-in image processing module, can generate scanning cloud picture to the image information obtained by laser detection head 21 through data processing, and compare it with built-in standard data cloud picture, to judge whether the thread of the drilling tool 01 to be detected is repaired.

[0038] A plurality of drill string thread parameters can be pre-stored in the control device 4. After the specification of the drill string 01 to be detected is input into the control device 4, if the drill string 01 to be detected can match a preset drill string thread parameter, the control device 4 controls the horizontal adjustment assembly to quickly adjust the laser detection head 21 to a preset position for scanning, so as to save the alignment time and improve the detection efficiency.

[0039] If the drill string 01 to be detected is of a special specification that cannot be matched, manual adjustment is required to realize the alignment of the laser detection head 21 and the drill string 01 to be detected.

[0040] In addition, in order to protect the personal safety of the detection personnel, a protective structure such as a protective plate or a protective cover is usually arranged outside the drill string transmission mechanism, and an audible and visual warning is arranged outside the protective structure to remind personnel to keep away and avoid the risk of personal injury, and to provide a good detection environment for drill string thread repair.

[0041] During detection, the drill string transmission mechanism is used to axially convey the drill string 01 to be detected to a position, and the horizontal adjustment assembly is used to arrange the center of the laser detection head 21 opposite the axis of the drill string 01 to be detected, so as to complete the alignment of the laser detection head 21 and the drill string 01 to be detected. Then, the image acquisition of the drill string thread and the shoulder surface 360° is completed by rotating the drill string 01 to cooperate with the laser detection head 21, and then the image information is processed and analyzed by the control device 4, so as to judge whether the thread damage exceeds the allowable range, and then judge whether the thread needs to be repaired.

[0042] In order to conveniently and quickly distinguish whether the drill string needs to be repaired, an automatic spraying assembly can also be arranged. When the control device 4 judges that the thread damage of the drill string 01 to be detected exceeds the allowable range, the automatic spraying assembly is used to automatically spray a corresponding mark on the drill string 01 to be detected.

[0043] In the embodiment, the automatic transmission, scanning and repair of the drill string thread are realized, which not only improves the thread repair quality and efficiency, but also is beneficial to the automatic recording of the thread quality inspection data, and facilitates the traceability of the drill string thread quality inspection.

[0044] On the basis of the above embodiment, the structure of the drill string transmission mechanism is limited. The drill string transmission mechanism comprises a transmission assembly for driving the drill string 01 to be detected to move along the axial direction and a rotating assembly for driving the drill string 01 to be detected to rotate. The transmission assembly comprises a plurality of moving pulleys 11 arranged along the axial direction of the drill string 01 to be detected. The axis of the moving pulley 11 is perpendicular to the axis of the drill string 01 to be detected, and the moving pulley 11 is connected with a moving motor.

[0045] The transmission assembly is used to drive the drill tool 01 to move along the axial direction. Considering that the drill tool 01 to be detected can be several meters long, in order to effectively support and transmit the drill tool 01 to be detected, a plurality of moving pulleys 11 are usually arranged to be uniformly distributed along the axial direction of the drill tool 01 to be detected. In order to avoid the drill tool 01 to be detected from moving radially during the axial movement, the moving pulleys 11 are usually arranged in a V-shaped pulley with high ends and low middle, rather than a cylindrical pulley.

[0046] The moving pulley 11 is connected with a moving motor. The moving motor drives the moving pulley 11 to rotate, and then drives the drill tool 01 to move along the axial direction through the friction between the moving pulley 11 and the drill tool 01 to be detected.

[0047] The rotating assembly is used to drive the drill tool 01 to rotate. In order to meet the rotating needs of the drill tool 01 of different sizes, especially different diameters, the rotating assembly is preferably arranged to include rotating wheel sets arranged at both ends of the drill tool 01 to be detected. The rotating wheel set is provided with two rotating wheels 12 rotating in the same direction. The axis of the rotating wheel 12 is parallel to the axis of the drill tool 01 to be detected. The axes of the two rotating wheels 12 of the same rotating wheel set are symmetrically distributed about the axis of the drill tool 01 to be detected.

[0048] When the rotating wheels 12 of the two rotating wheel sets rotate, the drill tool 01 to be detected can be driven to rotate through friction. The rotating speed of the drill tool 01 to be detected is determined according to the needs of accurate imaging of the laser detection head 21 in actual production, and is usually set to 0.5-3r / min. Then the rotating speed of the rotating wheel 12 and the diameter ratio of the rotating wheel 12 and the drill tool 01 to be detected are determined.

[0049] The two rotating wheels 12 in the same rotating wheel set can be driven by different rotating motors respectively, as long as the synchronous action is met.

[0050] In order to save equipment cost and simplify the structure of the rotating assembly, any rotating wheel 12 in the same rotating wheel set is preferably connected with a rotating motor. The rotating wheel 12 connected with the rotating motor is connected with another rotating wheel 12 through a transmission assembly such as a gear transmission assembly or a synchronous belt assembly. Therefore, when the rotating motor rotates, the rotating motor drives the rotating wheel 12 connected therewith to rotate, and then drives another rotating wheel 12 to rotate through the transmission assembly.

[0051] In order to facilitate the transmission and rotation of the drill tool 01 to be detected, the moving pulley 11 and the rotating wheel 12 are both provided with a transmission support at the bottom. The transmission support is used to lift the drill tool 01 to be detected, so as to avoid the drill tool 01 to be detected from contacting the ground. In order to reduce the height of the drill tool detection mechanism, the drill tool detection mechanism is also installed on the transmission support.

[0052] On the basis of the above-mentioned embodiments, the structure of the horizontal adjusting assembly is limited, the horizontal adjusting assembly comprises an X-axis adjusting assembly arranged along the axial direction of the drill tool 01 to be detected and a Y-axis adjusting assembly arranged along the vertical direction in the horizontal plane of the axial direction of the drill tool 01 to be detected, the laser detection head 21 is connected with the moving end of the X-axis adjusting assembly, and the fixed end of the X-axis adjusting assembly is connected with the moving end of the Y-axis adjusting assembly.

[0053] The adjustment range of the X-axis adjusting assembly is determined according to the entire axial length of the external thread and the shoulder surface of the drill tool 01 to be detected in actual production, so as to ensure that the field of view of the laser detection head 21 can cover the external thread and the shoulder surface of the drill tool 01 to be detected.

[0054] The adjustment range of the Y-axis adjusting assembly needs to be determined according to the diameter range of the drill tool 01 to be detected and the scanning range of the laser detection head 21 in actual production, so as to ensure that the circumferential edge of the drill tool 01 to be detected can fall into the field of view of the laser detection head 21.

[0055] Both the X-axis adjusting assembly and the Y-axis adjusting assembly can be arranged as a guide rail and a sliding block assembly, a ball screw assembly or the like, and the specific type, adjustment range and adjustment accuracy of both are determined according to the actual production requirements, and will not be described here.

[0056] When the X-axis adjusting assembly moves, the moving end thereof can drive the laser detection head 21 to move along the axial direction of the drill tool 01 to be detected, that is, the X-axis direction.

[0057] When the Y-axis adjusting assembly moves, the moving end thereof can drive the X-axis detection assembly to move along the axial direction of the drill tool 01 to be detected in the vertical direction in the horizontal plane, that is, the Y-axis direction, and further drive the laser detection head 21 to move along the Y-axis direction.

[0058] In the embodiment, the X-axis position and the Y-axis position of the laser detection head 21 are respectively adjusted by the X-axis adjusting assembly and the Y-axis adjusting assembly, so as to accurately adjust the horizontal position of the laser detection head 21, accurately align the laser detection head 21 with the drill tool 01 to be detected, ensure the image acquisition quality, and further ensure the accuracy and quality of the judgment and repair.

[0059] Preferably, the horizontal adjusting assembly further comprises a Z-axis adjusting assembly arranged along the height direction, the X-axis adjusting assembly is connected with the Y-axis adjusting assembly through the Z-axis adjusting assembly, the fixed end of the X-axis adjusting assembly is connected with the moving end of the Z-axis adjusting assembly, and the fixed end of the Z-axis adjusting assembly is connected with the moving end of the Y-axis adjusting assembly.

[0060] The Z-axis adjusting assembly can adjust the height of the laser detection head 21, when the detection accuracy requirement is not high and the detection efficiency is pursued, the Z-axis adjusting assembly can be controlled to raise the laser detection head 21, so as to increase the scanning range of the laser detection head 21 and complete the detection by one-time scanning.

[0061] When the detection accuracy is required to be high, the Z-axis adjusting assembly can be controlled to lower the laser detection head 21, so as to reduce the scanning range of the laser detection head 21, and the to-be-detected drill 01 is scanned in segments by two or more times, so as to improve the scanning accuracy.

[0062] Therefore, the Z-axis adjusting assembly can adjust the height of the laser detection head 21, and further adjust the scanning range of the laser detection head 21, so as to meet the requirements of different detection accuracies and detection efficiencies, and further meet the requirements of judging and repairing the drill of different sizes and specifications.

[0063] Preferably, the X-axis adjusting assembly, the Y-axis adjusting assembly and the Z-axis adjusting assembly have the same structure, and all are guide rail and sliding block assemblies and moving motors, and the extension rods of the moving motors are connected with the sliding blocks of the guide rail and sliding block assemblies.

[0064] Please refer to Figure 1 , the transmission support of the drill transmission mechanism is provided with a Y-axis guide rail of a Y-axis guide rail and sliding block assembly 24 along the Y-axis direction, the main support is slidably arranged on the Y-axis guide rail through a Y-axis sliding block, and the transmission support is provided with a Y-axis moving motor along the Y-axis direction, and the extension rod of the Y-axis moving motor is connected with the main support to drive the main support to slide along the Y-axis guide rail.

[0065] The main support is provided with a Z-axis guide rail of a Z-axis guide rail and sliding block assembly 23 along the height direction, the truss is slidably arranged on the Z-axis guide rail through a Z-axis sliding block, and the main support is provided with a Z-axis moving motor along the Z-axis direction, and the extension rod of the Z-axis moving motor is connected with the truss to drive the truss to move along the Z-axis guide rail.

[0066] The truss is provided with an X-axis guide rail of an X-axis guide rail and sliding block assembly 22 along the X-axis direction, the laser detection head 21 is slidably arranged on the X-axis guide rail through an X-axis sliding block, and the truss is provided with an X-axis moving motor along the X-axis direction, and the extension rod of the X-axis moving motor is connected with the laser detection head 21 to drive the laser detection head 21 to move along the X-axis guide rail.

[0067] On the basis of the above embodiment, in order to detect whether the to-be-detected drill 01 is axially in place, a to-be-in-place detection assembly can also be arranged, the to-be-in-place detection assembly is used for detecting whether the to-be-detected drill 01 is axially in place, and the to-be-in-place detection assembly is signal connected with the control device 4, so that the control device 4 controls the drill transmission mechanism to stop driving the to-be-detected drill 01 to continue to move along the axial direction after the to-be-detected drill 01 is axially in place.

[0068] The to-be-in-place detection assembly can be a to-be-in-place detection sensor, which can be specifically an optical sensor, a proximity switch or the like, when the to-be-detected drill 01 is axially in place, the to-be-in-place detection sensor transmits an axial in-place signal to the control device 4, and the drill transmission mechanism stops driving the to-be-detected drill 01 to continue to move along the axial direction.

[0070] When the drill tool 01 to be detected abuts against the positioning block 3, the drill tool 01 to be detected is axially in position, and the control device 4 controls the positioning block moving assembly to move the positioning block 3 to the working position, so as to avoid the positioning block 3 interfering with the rotation of the drill tool 01 to be detected.

[0071] In order to avoid the positioning block 3 from moving in the moving process, the positioning block 3 can be arranged to slide in a sliding groove of the transmission support, and in order to shorten the moving stroke of the positioning block 3, the positioning block moving assembly is usually arranged as a linear motor arranged along the axial direction of the drill tool 01 to be detected.
