Description

TECHNICAL FIELD

[0001] The application relates to the field of ultrasonic detection equipment, in particular to a clamping mechanism of an automatic crawling ultrasonic detector for nickel pipe welds. BACKGROUND

[0002] At present, nickel pipes are widely applied in the fields of chemical industry and energy sources due to excellent corrosion resistance and high-temperature stability, and the weld quality of the nickel pipes directly affects the safety of the pipeline system. Traditional nickel pipe weld detection depends on manual operation of ultrasonic equipment, and the probe position needs to be manually adjusted outside or inside the pipeline, which is high in labor intensity, and it is difficult to ensure detection continuity in long-distance and large-diameter nickel pipes, and the detection is prone to omissions due to operation errors. The clamping mechanism of the existing automatic crawling detection equipment has obvious defects: first, the structure is rigid, and it is difficult to adapt to nickel pipes with different diameters, and the flexibility is insufficient when entering narrow pipelines; second, the support stability is poor, and the probe is prone to poor adhesion to the pipe wall during the crawling process, affecting ultrasonic signal collection; third, the pretreatment function is lack of integration, manual cleaning of the weld area and coating of a coupling agent are needed before detection, which is low in efficiency and uneven in coupling effect, in addition, the positioning accuracy of part of the equipment is insufficient, and the detection position cannot be accurately fed back, which brings difficulties to defect tracing in the later period. These problems make it difficult for the existing equipment to meet the demand for efficient and accurate detection of nickel pipe welds, and therefore, the clamping mechanism of the automatic crawling ultrasonic detector for nickel pipe welds is proposed to solve the above-mentioned problems.

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1. In the initial state, the two electric push rods are in an elongated state, and through the linkage of the rotating head and the connecting rod, each supporting rod can be driven to move closer to each other, so that the device is folded into an elongated "strip-shaped" structure. This design greatly optimizes the smoothness of the device entering the pipe, especially for narrow or long distance pipe scenes. When the device enters the front end of the pipe, the remote control electric push rod is retracted, and the supporting rod is driven to open through the rotating head and the connecting rod, so that the end guide wheel tightly abuts against the inner wall of the pipe, and stable support is realized, laying a foundation for subsequent detection work. Compared with the rigid structure of the traditional device, the folding and self-adaptive support design of the present application significantly improves the applicability in complex pipe environment.

[0016] 2、The servo motor at the front end of the equipment can drive the rotating seat to deflect, so that the front end mounting frame is vertically adjusted, and meanwhile, the guide wheel is driven by the stepping motor to be inclined together with the mounting frame, and the hollow motor drives the rotation of the rotating frame and the supporting rod, so that the overall movement of the equipment in the pipe material can be realized, and different diameters of pipe materials can be flexibly adapted, in the movement process, the wheel hub motor of the fixed bin drives the fixed frame to rotate, so that the light supplementing lamp and the camera rotate synchronously, not only can the inside weld of the pipe material be shot in real time and transmitted to the external receiving equipment, the position of the weld is assisted to be positioned, but also the real-time coordinates of the equipment in the pipeline can be accurately fed back, the problem of "difficult positioning" in the detection of long-length pipelines is effectively solved, the adaptability to different pipe diameters and the detection flexibility are enhanced, compared with the manual positioning or segmented detection mode of the prior art, the efficiency is significantly improved.

[0017] 3、After the equipment reaches the detection position, the guide wheel can be controlled to be transversely arranged first, the shell end air pump is started, and the detection part is cleaned through the pressurized airflow. In this process, the reaction force generated by the air pump suction and air injection makes the shell deflect, and the reset spring on the fixed shaft is matched to realize the swing of the shell, so that the cleaning range is greatly expanded, the interference of impurities on the detection result is avoided, the cleaning effect before detection and the coupling liquid coating effect are optimized, and compared with the traditional manual cleaning or fixed angle cleaning, the cleaning efficiency and cleanliness are significantly improved.

[0018] 4、The application is more innovative in the coupling liquid coating link: the hollow motor adjusts the positions of the front end and the tail end supporting rods, so that the shell is attached to the inner wall of the pipe material; the guide frame drives the moving part to extend out of the slot, and the inclination angle is accurately adjusted under the traction of the magnet, so that the moving part is always directed towards the shell; the pump body draws the coupling liquid through the hose, and the coupling liquid is uniformly sprayed around the weld to be detected through the nozzle by the conduit, at the same time, the hollow motor drives the equipment to rotate, so that the coupling liquid uniformly covers the two sides of the weld, and the shell further smoothes the coupling liquid, so as to provide a stable acoustic impedance transmission environment for ultrasonic detection. Compared with the manual coating or fixed point spraying mode in the prior art, the coupling effect is more uniform, and the problems of waste of coupling agent or insufficient coating are avoided.

[0019] 5、After the coupling liquid coating is completed, the ultrasonic probe inside the shell is started, and the weld is detected in 360° under the drive of the hollow motor, and the detection data is transmitted to the external equipment in real time, after the unilateral detection is completed, the structure on the other side of the equipment is adjusted symmetrically, so that the synchronous detection of the other side of the weld can be realized. Compared with the traditional single-direction detection or the mode that needs to adjust the position of the equipment multiple times, the bidirectional symmetric detection design of the application greatly reduces the detection blind area, improves the recognition accuracy of the weld defects (such as cracks and incomplete penetration), improves the comprehensiveness and accuracy of the weld detection, and is more in line with the high-standard detection requirements of industrial pipelines.

[0030] Further, in the specific implementation, in the process of the device moving inside the pipe 109, the wheel hub motor in the middle of the fixed warehouse 104 works, each fixed frame 101 can be driven to rotate by the wheel hub motor, the light supplement lamp 102 and the camera 103 can be rotated inside the pipe 109 by the rotation of the fixed frame 101, so that the inside of the pipe 109 can be imaged by the light supplement lamp 102 and the camera 103 and transmitted to the receiving device in the hands of the outside people, to assist people to determine the weld position inside the pipe 109, and can help people to determine the position of the device inside the pipe outside, which is beneficial to the detection work of long length pipe, the support rod 105 and the guide wheel 106 at the advancing end can be rotated by the hollow motor 108, when the adjustment is completed, the support rod 105 at the tail end can be retracted by the work of the rotating frame 111, then the step motor on the rotating seat 124 at the tail end support rod 105 end part starts to work, so that the mounting bracket 107 can be deflected, so that the guide wheel 106 and the shell 123 can exchange the inside and outside positions, so that the shell 123 can be attached to the inside wall of the pipe 109, then the support rod 105 at the tail end is opened by the rotating frame 111, realizing the stable support of the tail end, at this time, the rotating frame 111 at the advancing end is retracted, then the rotating seat 124 and the mounting bracket 107 are deflected by the motor base 112, after that, the operation of the tail end is repeated, the position of the guide wheel 106 and the shell 123 at the advancing end is adjusted, so that the shell 123 at the advancing end is also attached to the inside wall of the pipe 109.

[0031] The end of the rotating seat 124 is fixedly connected with the mounting rack 107, one side of the mounting rack 107 is provided with the side frame 122, the inner side of the part of the mounting rack 107 away from the rotating seat 124 is rotatably connected with the guide wheel 106, the inner side of the part of the side frame 122 away from the rotating seat 124 is provided with the shell 123, both ends of the shell 123 are fixedly connected with the fixed shaft 125, the fixed shaft 125 is rotatably connected with the side frame 122, the reset torsional spring is arranged between the fixed shaft 125 and the side frame 122, the inner side of the end of the shell 123 away from the rotating seat 124 is provided with the air pump 127, the inner side of the end of the shell 123 close to the rotating seat 124 is provided with the ultrasonic probe 126, and the ultrasonic probe 126 is used for detecting the weld of the pipe 109.

[0032] Further, in specific implementation, people can detect the welding defects of the pipe 109 through the equipment. In the initial state, the electric push rods 110 on both sides are in the elongated state, so that the rotating heads 116 on both sides drive the connecting rods 115 to pull the support rods 105 close to each other, so that the equipment is in a folded state, so that the equipment presents an elongated "strip shape", so that the equipment can more smoothly enter the pipe, in the working process, after people put the equipment into the inside of the front end of the pipe 109, people can remotely start the electric push rod 110, and the electric push rod 110 can drive the rotating heads 116 on both sides to move, and the rotating heads 116 can drive the support rods 105 to open through the connecting rods 115, so that the guide wheels 106 at the ends of the support rods 105 can abut against the inner wall of the pipe 109, and the equipment can be supported in the pipe 109 through the guide wheels 106 on both sides, so as to facilitate the subsequent detection work, in this process, the servo motor in the front end motor seat 112 can drive the rotating seat 124 to deflect, so that the mounting rack 107 of the front end can be vertical, while the tail end remains unchanged, at the same time, the step motor in the rotating seat 124 of the front end can drive the guide wheels 106 and the mounting rack 107 of the front end to deflect, so that the guide wheels 106 of the front end are inclined by an angle, at this time, the hollow motor 108 of the front end starts to work, and the rotating shafts 111 and the support rods 105 of the front end can be driven to rotate through the work of the hollow motor 108, and the equipment can be moved in the pipe 109 through the guide wheels 106 inclined at the ends of the support rods 105 of the front end, so that the equipment can adapt to pipes 109 of different diameters.

[0033] The middle part of the supporting rod 105 is rotatably connected with a connecting rod 115 near one side of the electric push rod 110, and the end of the connecting rod 115 away from the supporting rod 105 is rotatably connected with a rotating head 116, and the rotating head 116 is rotatably connected to the end of the electric push rod 110. The side of the rotating frame 111 near the fixed bin 104 is provided with a hollow motor 108, and the hollow motor 108 is installed at both ends of the fixed bin 104. The inner side driving part of the hollow motor 108 is fixedly connected with the rotating frame 111.

[0034] Further, in specific implementation, the work of the hollow motor 108 can drive the whole end of the equipment to rotate, so that the coupling liquid can be uniformly coated on the two sides of the weld to be contacted, which is beneficial to the subsequent detection work. During the coating of the coupling liquid, the shell 123 can evenly wipe the contacted coupling liquid, which is beneficial to the subsequent detection work. Then the guide frame 119 and the internal pump body stop working and are retracted. At this time, the ultrasonic probe 126 inside the shell 123 starts to work. During the rotation of the hollow motor 108, the weld inside the pipe 109 is detected, and the detection result is directly transmitted to the receiving device in the hand of the person. When the detection on one side is completed, the above-mentioned action is repeated on the other side of the equipment to realize the detection on the other side of the weld, which is beneficial to the actual use.

[0035] The middle part of the supporting rod 105 is rotatably connected with a connecting rod 115 near one side of the electric push rod 110, and the end of the connecting rod 115 away from the supporting rod 105 is rotatably connected with a rotating head 116, and the rotating head 116 is rotatably connected to the end of the electric push rod 110. The side of the rotating frame 111 near the fixed bin 104 is provided with a hollow motor 108, and the hollow motor 108 is installed at both ends of the fixed bin 104. The inner side driving part of the hollow motor 108 is fixedly connected with the rotating frame 111.

[0036] Further, in specific implementation, after the device reaches the position to be detected, one can first control the guide wheel 106 to directly move horizontally and start the air pump 127 at the side end of the shell 123. Through the operation of the air pump 127, air flow can be directly guided and pressurized to be sprayed out, so as to clean the subsequent position to be detected. In this process, the air suction and paint spraying of the air pump 127 will cause the shell 123 to be deflected. Under the cooperation of the reset spring installed at the shaft part of the fixed shaft 125, the shell 123 will swing when the air is sprayed, so as to further improve the cleaning range of the shell 123, which is beneficial to the subsequent detection work. When the supporting rod 105 is stretched, the guide frame 119 inside the slot 113 will start to work, so that the moving part 114 will be elongated along the guide frame 119. Under the guidance of the oblique cutting surface at the end of the moving part 114, the moving part 114 will be lifted as a whole and "float" out of the slot 113. In this process, when the moving part 114 is elongated, the end of the moving part 114 will enter the influence range of the magnet embedded at the end of the shell 123, so as to drag the end of the moving part 114, so as to adjust the inclination angle of the moving part 114, so that the end of the moving part 114 always faces the shell 123. At this time, the pump body inside the guide frame 119 starts to work. Through the operation of the pump body, the coupling liquid inside the supporting rod 105 can be extracted through the hose 121 and can be transported through the conduit 117, and finally sprayed out through the nozzle 118, so that the part to be contacted with the shell 123 around the weld can be coated with the coupling liquid.

[0037] Working principle:

[0038] In actual use, people can detect the welding defects of the pipe 109 through the device. In the initial state, the electric push rods 110 on both sides are in the elongated state, so that the rotating heads 116 on both sides drive the connecting rods 115 to pull the support rods 105 close to each other, so that the device is in a folded state, and the device assumes an elongated "strip shape", so that the device can more smoothly enter the pipe. After the device is placed into the front end of the pipe 109, people can remotely start the electric push rods 110. Through the work of the electric push rods 110, the rotating heads 116 on both sides can be moved, and through the rotating heads 116, the support rods 105 can be driven to open by the connecting rods 115, so that the guide wheels 106 installed at the ends of the support rods 105 can abut against the inner side wall of the pipe 109. Through the guide wheels 106 on both sides, the device can be supported inside the pipe 109, facilitating subsequent detection work. In this process, the servo motor in the front end motor base 112 can drive the rotating seat 124 to deflect so that the mounting frame 107 at the front end can be upright, while the tail end remains unchanged. At the same time, the step motor in the front end rotating seat 124 can drive the guide wheels 106 and the mounting frame 107 at the front end to deflect, so that the guide wheels 106 at the front end are all inclined at an angle. At this time, the hollow motor 108 at the front end will start to work. Through the work of the hollow motor 108, the rotating shafts 111 and the support rods 105 at the front end can be rotated. Through the guide wheels 106 at the ends of the support rods 105 at the front end, the device can be moved as a whole inside the pipe 109, so that the device can adapt to pipes 109 of different diameters. In the process of moving the device inside the pipe 109, the wheel hub motor in the middle of the fixed bin 104 works. Through the wheel hub motor, the fixed frame 101 can be rotated. Through the rotation of the fixed frame 101, the light supplement lamp 102 and the camera 103 can be rotated inside the pipe 109, so that the inside of the pipe 109 can be imaged by the light supplement lamp 102 and the camera 103, and transmitted to the receiving device in people's hands outside, to help people determine the position of the weld inside the pipe 109, and to help people determine the position of the device inside the pipe. It is beneficial to the detection work of long pipes. After the device reaches the position to be detected, people can first control the guide wheels 106 to be directly transverse, and start the air pump 127 at one end of the housing 123. Through the work of the air pump 127, air flow can be directly guided and pressurized to be sprayed, to clean the subsequent part to be detected. In this process, the suction and paint spraying work of the air pump 127 will make the housing 123 deflect. Under the cooperation of the reset spring installed on the shaft of the fixed shaft 125, the housing 123 will swing when spraying, so as to further improve the cleaning range of the housing 123, which is beneficial to the subsequent detection work. Then, through the hollow motor 108, the support rods 105 and the guide wheels 106 at the front end can be rotated,Thus, the device position can be adjusted according to the weld position. When the adjustment is completed, the tail end support rod 105 can be retracted first by the operation of the rotating frame 111. Then the step motor on the end rotating seat 124 of the tail end support rod 105 can start to work, thereby driving the mounting frame 107 to deflect, so that the guide wheel 106 and the shell 123 can exchange the inside and outside positions, so that the shell 123 can be attached to the inner wall of the pipe 109. Then the tail end support rod 105 is expanded by the rotating frame 111 to realize stable support of the tail end. At this time, the rotating frame 111 at the advancing end is retracted, and the rotating seat 124 and the mounting frame 107 are deflected and reset by the motor seat 112. After that, the operation of the tail end is repeated to adjust the position of the advancing end guide wheel 106 and the shell 123, so that the shell 123 at the advancing end is also attached to the inner wall of the pipe 109. In this process, when the support rod 105 is expanded, the guide frame 119 inside the slot 113 will start to work, so that the moving part 114 will be elongated along the guide frame 119. Under the guidance of the oblique cutting surface at the end of the moving part 114, the moving part 114 and the guide frame 119 will be lifted as a whole and "float" out of the slot 113. In this process, when the moving part 114 is elongated, the end of the moving part 114 will enter the influence range of the magnet embedded at the end of the shell 123, thereby pulling the end of the moving part 114 to adjust the inclination angle of the moving part 114, so that the end of the moving part 114 always faces the shell 123. At this time, the pump body inside the guide frame 119 starts to work. Through the work of the pump body, the coupling liquid inside the support rod 105 can be pumped out through the hose 121 and transported through the conduit 117. Finally, the coupling liquid is sprayed out through the nozzle 118, so that the part to be contacted with the shell 123 around the weld can be coated with the coupling liquid. The work of the hollow motor 108 can drive the whole device to rotate, so that the coupling liquid can be uniformly coated on the two sides of the weld to be contacted, which is beneficial to the subsequent detection work. During the coating of the coupling liquid, the shell 123 can evenly wipe the coupling liquid, which is beneficial to the subsequent detection work. Then the guide frame 119 and the internal pump body stop working and are retracted. At this time, the ultrasonic probe 126 inside the shell 123 starts to work. During the rotation of the hollow motor 108, the weld inside the pipe 109 is detected. The detection result will be directly transmitted to the receiving device in people's hands. When the detection on one side is completed, the detection on the other side can be realized by repeating the above operation, which is beneficial to actual use.
