Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic detection devices, and in particular to a pipeline defect ultrasonic detection device. Background Art

[0002] The ultrasonic detection device for pipeline defects is a device that uses ultrasonic technology to detect and evaluate internal defects in pipelines. The ultrasonic detection device is based on the principle of ultrasonic propagation and reflection in materials. When ultrasonic waves propagate in pipeline materials, if they encounter defects (such as cracks, incomplete welds, slag inclusions, etc.) or interfaces, the ultrasonic waves will be reflected, refracted or scattered. By receiving and analyzing these reflected waves, the defect information inside the pipeline can be obtained, such as the size, location and nature of the defects.

[0003] After being put into use, the existing ultrasonic detection device for pipeline defects generally uses a walking trolley to apply coupling agent to the inner wall of the pipeline. However, it is difficult for the walking trolley to enter the interior of a shorter pipeline when applying the coupling agent, which makes the application more difficult. Improvements are needed to address this problem. Summary of the invention

The liquid storage bag is fixedly connected to the middle of the bottom of the lifting and rotating cylinder, the ring tube is fixedly connected to the outside of the liquid storage bag, the connecting hose is fixedly connected to the outside of the ring tube, and the drainage groove is opened in the middle of the sponge block.

[0010] According to the above technical solution, the bottom of the fixed plate is fixedly connected to the top of the electric telescopic rod, the telescopic end of the electric telescopic rod passes through the inner wall of the bottom of the working cylinder, the top of the lifting and rotating cylinder and extends into the lifting and rotating cylinder and is fixedly connected to the top of the lifting plate, so that the electric telescopic rod controls the movement of the lifting plate during work.

[0011] According to the above technical solution, the adjusting rod is rotatably connected to the middle of the first positioning frame at one side away from the second positioning frame, and the pair of adjusting rods of the positioning frame are used for rotational adjustment when the lifting plate moves.

[0012] According to the above technical solution, a sliding groove is provided in the lifting plate, and the lifting plate is slidably connected to the outer wall of the lifting rotating cylinder through the sliding groove, so that the lifting plate can be lifted and lowered on the outer wall of the lifting rotating cylinder.

[0013] According to the above technical solution, the sliding wheels are slidably connected to the front and back inner walls of the guide frame, and the moving block is slidably connected to the inner wall of the guide frame through the sliding wheels, so that the sliding wheels slide on the inner wall of the guide frame.

[0014] According to the above technical solution, a coupling agent is arranged in the liquid storage capsule, and the connecting hose passes through the arc plate and extends into the sponge block, so that the coupling agent in the liquid storage capsule can be introduced into the drainage groove through the annular tube and the connecting hose, and the coupling agent can be absorbed by the drainage groove and evenly spread.

[0015] According to the above technical solution, the detection component also includes telescopic rod one, telescopic rod two, an adjusting box, a connecting pipe, a spring and a scraper plate. The telescopic rod one is fixedly connected to the top of the outer side of the arc plate, the telescopic rod two is fixedly connected to the bottom of the outer side of the arc plate, the adjusting box is fixedly connected between the telescopic rod one and the telescopic rod two, the connecting pipe is fixedly connected to the top and bottom of the adjusting box, the spring is fixedly connected to one side of the adjusting box close to the lifting and rotating cylinder, and the scraper plate is fixedly connected to the other side of the spring.

[0016] According to the above technical solution, the detection component also includes telescopic rod 1, telescopic rod 2 and an adjustment box, wherein telescopic rod 1 is fixedly connected to the top of the outer side of the arc plate, telescopic rod 2 is fixedly connected to the bottom of the outer side of the arc plate, and the adjustment box is fixedly connected between telescopic rod 1 and telescopic rod 2.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the coupling agent needs to be applied to the inner wall of the pipeline, the present invention controls the electric telescopic rod to work, and controls the lifting plate to move downward when the electric telescopic rod is working. When the lifting plate moves downward, the positioning frame 1 on the lifting plate pushes the adjusting rod, and the adjusting rod pushes the positioning frame 2, so that the positioning frame 2 pushes the arc plate, and at the same time, the arc plate drives the sliding rod and the moving block to move, so that the sliding wheel on the moving block slides on the inner wall of the guide frame, and the arc plate can be guided when it moves, so that the arc plate moves toward the outside of the lifting rotating cylinder, and the sponge block on the arc plate contacts the inner wall of the pipeline, and then the driving motor is controlled to work, and the driving motor drives the working cylinder to rotate through the fixed disk when working, and at the same time, when the sponge block contacts the inner wall of the pipeline, the inner wall of the pipeline is rubbed and cleaned, so as to avoid dust and oil stains adhering to the inner wall of the pipeline and causing errors during detection;

[0018] After the inner wall of the pipeline is cleaned by the sponge block, the oil stains adhering to the sponge block are manually cleaned, and then the electric telescopic rod is controlled to work, so that the electric telescopic rod drives the lifting plate to move down to contact the top of the liquid storage bag, and squeezes the liquid storage bag at the same time. When the liquid storage bag is squeezed, the coupling agent in the liquid storage bag flows into the ring pipe and the connecting hose, and flows out through the drainage groove on the sponge block. At the same time, the coupling agent is absorbed by the sponge block, and then the electric telescopic rod is adjusted to move the lifting plate, and the positioning frame on the lifting plate controls the moving distance of the arc plate, so that the sponge block on the arc plate can be inserted into the pipeline, and the driving motor is controlled to work to rotate the sponge block and apply the coupling agent to the inner wall of the pipeline;

[0019] After the electric telescopic rod controls the lifting plate to move downward to squeeze the liquid storage capsule, the device is reversed so that the guide frame is located on the upper side and the handle is located on the lower side. After the electric telescopic rod controls the lifting plate to move and separates the lifting plate from the liquid storage capsule, the elasticity of the liquid storage capsule is restored and negative pressure is generated in the liquid storage capsule. At the same time, under the action of gravity, the sponge block absorbs excessive coupling agent and accumulates it in the drainage groove, which is located outside the connecting hose. At this time, the negative pressure in the liquid storage capsule re-absorbs the coupling agent in the drainage groove into the liquid storage capsule through the connecting hose, avoiding waste of coupling agent during use.

[0020] When testing is needed, the coupling agent is evenly applied to the inner wall of the pipeline through a sponge block, and the detection head is in contact with the inner wall of the pipeline. Then, the ultrasonic flaw detector is turned on so that the detection head can detect the inner wall of the pipeline. The driving motor is controlled so that the driving motor can drive the detection head to rotate, and the device can directly perform testing after the coupling agent is applied;

[0021] Before applying the coupling agent, the inner wall of the pipeline needs to be cleaned, and the lifting plate is controlled to rise so that the lifting plate drives the arc plate to move to the outside of the lifting rotating cylinder when rising. At the same time, the distance between the multiple arc plates on the outside of the lifting rotating cylinder is shortened, so that the telescopic ends on both sides of the telescopic rod one move toward the inside of the telescopic rod one, and the air in the telescopic rod one is filled into the regulating box through the connecting pipe to increase the pressure in the regulating box, and push the spring to stretch, so that the scraper plate is exposed from the regulating box, and when it contacts the inner wall of the pipeline, the driving motor is controlled to work, so that the scraper plate can scrape off the dust and oil adhered to the inner wall of the pipeline, so as to facilitate the cleaning of the inner wall of the pipeline, and at the same time, it is pulled out after cleaning, and its surface is cleaned;

[0022] At the same time, when applying the coupling agent later, the lifting plate moves downward, causing the arc plate to move away from the lifting rotating cylinder. At this time, the telescopic ends on both sides of the telescopic rod 1 extend as the arc plate moves, causing negative pressure in the telescopic rod 1, and sucking the air in the adjustment box into the telescopic rod 1 through the connecting pipe. At this time, the spring elasticity is restored, and the scraper plate is restored to a horizontal state with the outer side of the adjustment box, which will not cause interference when applying the coupling agent later. At the same time, the coupling agent can be evenly distributed, making the coupling agent more evenly applied;

[0023] After the inspection is completed, the lifting plate is controlled to rise, so that the scraper plate is exposed from the adjustment box, and the outer side of the scraper plate contacts the inner wall of the pipe. Then the drive motor is controlled to work, so that the scraper plate can scrape off the remaining coupling agent on the inner wall of the pipe, so that the device can avoid coupling agent residue after use. The coupling agent residue may form microcracks or pores on the surface of the workpiece, reducing the strength and toughness of the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The coupling agent storage assembly 6 includes a liquid storage bag 601, an annular tube 602, a connecting hose 603 and a liquid drainage groove 604. The liquid storage bag 601 is fixedly connected to the middle of the bottom of the lifting and rotating cylinder 404, the annular tube 602 is fixedly connected to the outside of the liquid storage bag 601, the connecting hose 603 is fixedly connected to the outside of the annular tube 602, and the liquid drainage groove 604 is opened in the middle of the sponge block 508.

[0046] The adjusting rod 510 is rotatably connected to the middle of the positioning frame 1 502 at one side away from the positioning frame 2 509 , and the adjusting rod 510 is rotationally adjusted through the positioning frame 1 502 when the lifting plate 501 moves.

[0047] A sliding groove is provided in the lifting plate 501 , and the lifting plate 501 is slidably connected to the outer wall of the lifting rotating cylinder 404 through the sliding groove, so that the lifting plate 501 can be lifted and lowered on the outer wall of the lifting rotating cylinder 404 .

[0048] The sliding wheel 506 is slidably connected to the front and back inner walls of the guide frame 503 , and the moving block 505 is slidably connected to the inner wall of the guide frame 503 through the sliding wheel 506 , so that the sliding wheel 506 slides on the inner wall of the guide frame 503 .

[0049] The liquid reservoir 601 is provided with coupling agent, and the connecting hose 603 passes through the arc plate 507 and extends into the sponge block 508, so that the coupling agent in the liquid reservoir 601 can be introduced into the drainage groove 604 through the annular tube 602 and the connecting hose 603, and the coupling agent is absorbed by the drainage groove 604 and evenly spread.

[0050] When the coupling agent needs to be applied to the inner wall of the pipeline, the electric telescopic rod 403 is controlled to work, and the lifting plate 501 is controlled to move downward when the electric telescopic rod 403 is working. When the lifting plate 501 moves downward, the positioning frame 1 502 on the lifting plate 501 pushes the adjusting rod 510, and the adjusting rod 510 pushes the positioning frame 2 509, so that the positioning frame 2 509 pushes the arc plate 507, and at the same time, the arc plate 507 drives the sliding rod 504 and the moving block 505 to move, so that the sliding wheel 506 on the moving block 505 moves on the guide frame 5 03 slides on the inner wall, which can guide the arc plate 507 when it moves, so that the arc plate 507 moves toward the outside of the lifting and rotating cylinder 404, and the sponge block 508 on the arc plate 507 contacts the inner wall of the pipe, and then the drive motor 401 is controlled to work, and the drive motor 401 drives the working cylinder 2 to rotate through the fixed plate 3 when working, and at the same time, when the sponge block 508 contacts the inner wall of the pipe, the inner wall of the pipe is rubbed and cleaned to prevent dust and oil from adhering to the inner wall of the pipe and causing errors during detection.

[0051] After the inner wall of the pipeline is cleaned by the sponge block 508, the oil stains adhering to the sponge block 508 are manually cleaned, and then the electric telescopic rod 403 is controlled to work, so that the electric telescopic rod 403 drives the lifting plate 501 to move downward to contact the top of the liquid storage capsule 601, and at the same time squeezes the liquid storage capsule 601. When the liquid storage capsule 601 is squeezed, the coupling agent in the liquid storage capsule 601 flows into the annular tube 602 and the connecting hose 603, and flows out through the drainage groove 604 on the sponge block 508. At the same time, the coupling agent is absorbed by the sponge block 508, and then the electric telescopic rod 403 is adjusted to work to move the lifting plate 501, and the positioning frame 502 on the lifting plate 501 controls the moving distance of the arc plate 507, so that the sponge block 508 on the arc plate 507 can be inserted into the pipeline, and the driving motor 401 is controlled to work to rotate the sponge block 508 and apply the coupling agent to the inner wall of the pipeline.

[0052] After the electric telescopic rod 403 controls the lifting plate 501 to move downward to squeeze the liquid storage capsule 601, the device is reversed so that the guide frame 503 is located on the upper side and the handle 1 is located on the lower side. After the electric telescopic rod 403 controls the lifting plate 501 to move and separates the lifting plate 501 from the liquid storage capsule 601, the elasticity of the liquid storage capsule 601 is restored and negative pressure is generated in the liquid storage capsule 601. At the same time, under the action of gravity, the excess coupling agent absorbed by the sponge block 508 is accumulated in the drainage groove 604 and is located on the outside of the connecting hose 603. At this time, the negative pressure in the liquid storage capsule 601 re-sucks the coupling agent in the drainage groove 604 into the liquid storage capsule 601 through the connecting hose 603, thereby avoiding waste of coupling agent during use.

[0053] The detection component 7 includes an ultrasonic flaw detector 701, a connecting wire 1 702, a conductive slip ring 703, a connecting wire 2 704 and a detection head 705. The ultrasonic flaw detector 701 is fixedly connected to the top of the handle 1, the connecting wire 1 702 is fixedly connected to the bottom of the ultrasonic flaw detector 701, the conductive slip ring 703 is fixedly connected to the top of the outer side of the working cylinder 2, the connecting wire 2 704 is fixedly connected to the conductive slip ring 703, the detection head 705 is fixedly connected to the side of the connecting wire 2 704 away from the conductive slip ring 703, the top of the detection head 705 is fixedly connected to the bottom of the arc plate 507 and the sponge block 508, and the connecting wire 1 702 and the connecting wire 2 704 are electrically connected through the conductive slip ring 703.

[0054] The detection assembly 7 also includes a telescopic rod 1 706, a telescopic rod 2 707 and an adjustment box 708.

[0055] When inspection is required, the sponge block 508 is used to evenly apply coupling agent to the inner wall of the pipeline, and the detection head 705 is in contact with the inner wall of the pipeline. Then, the ultrasonic flaw detector 701 is turned on so that the detection head 705 can perform flaw detection on the inner wall of the pipeline. The driving motor 401 is controlled so that the driving motor 401 can drive the detection head 705 to rotate, so that the device can directly perform inspection work after the coupling agent is applied.

[0056] Before applying the coupling agent, the inner wall of the pipeline needs to be cleaned, and the lifting plate 501 is controlled to rise, so that the lifting plate 501 drives the arc plate 507 to move to the outside of the lifting rotating cylinder 404 when rising, and at the same time, the distance between the multiple arc plates 507 on the outside of the lifting rotating cylinder 404 is shortened, so that the telescopic ends on both sides of the telescopic rod 1 706 move toward the inside of the telescopic rod 1 706, and the air in the telescopic rod 1 706 is filled into the regulating box 708 through the connecting pipe 709, so that the pressure in the regulating box 708 is increased, and the spring 710 is pushed to stretch, so that the scraper plate 711 is exposed from the regulating box 708, and when it contacts the inner wall of the pipeline, the driving motor 401 is controlled to work, so that the scraper plate 711 can scrape off the dust and oil adhered to the inner wall of the pipeline, so as to facilitate the cleaning of the inner wall of the pipeline, and at the same time, it is pulled out after cleaning, and its surface is cleaned;

[0057] At the same time, when applying the coupling agent later, the lifting plate 501 moves downward, so that the arc plate 507 moves away from the lifting rotating cylinder 404. At this time, the telescopic ends on both sides of the telescopic rod 706 extend as the arc plate 507 moves, so that negative pressure is generated in the telescopic rod 706, and the air in the adjustment box 708 is sucked into the telescopic rod 706 through the connecting pipe 709. At this time, the spring 710 elastically recovers and the scraper plate 711 is restored to a horizontal state with the outer side of the adjustment box 708, which will not cause interference when applying the coupling agent later. At the same time, the coupling agent can be evenly distributed, so that the coupling agent is applied more evenly;

[0058] After the detection is completed, the lifting plate 501 is controlled to rise, so that the scraper plate 711 is exposed from the adjustment box 708, and the outer side of the scraper plate 711 contacts the inner wall of the pipe, and then the drive motor 401 is controlled to work, so that the scraper plate 711 can scrape off the coupling agent remaining on the inner wall of the pipe, and stand the pipe vertically. Under the action of centrifugal force and gravity, the scraped coupling agent flows out from the lower side of the pipe along the inner wall of the pipe, so that the device can avoid coupling agent residue after use. The coupling agent residue may form microcracks or pores on the surface of the workpiece, reducing the strength and toughness of the material.
