Description

Technical Field

[0001] The present application belongs to the technical field of ultrasonic nondestructive testing, and specifically relates to a magnetostrictive guided wave detection probe auxiliary device and an application method. Background Art

[0002] Ultrasonic guided waves are a type of mechanical elastic wave that can propagate rapidly along the limited boundary shape of a structural component and is constrained and guided by the boundary shape of the component. Starting from the sensor installation position, it can propagate rapidly in both directions along the pipeline and instantly complete 100% volume scanning and detection of a pipe section from tens to hundreds of meters long. Since the system does not need to be shut down during the detection process, the detection method is simple, fast, and has a high coverage rate, it is increasingly widely used in pipeline detection.

[0003] According to the different waveguide excitation principles, waveguide detection can be divided into several types. Among them, the detection method that uses the magnetostrictive principle to generate ultrasonic waveguides from magnetostrictive tapes can not only detect magnetic metal materials, but also has good detection effects on non-metallic dense sound-conducting materials. During magnetostrictive waveguide detection, first stick the magnetostrictive tape on the surface of the pipeline, and then push the pipeline detection probe with a pulley to walk on the pipe wall at a uniform speed to complete the detection of the entire pipeline. When detecting pipelines with good spatial positions, the above detection process is relatively easy to implement, but when detecting some large pipelines, or pipelines that are very close to the ground, walls, etc., due to spatial limitations, only local pipelines can be detected, and the detection of the entire circumference becomes difficult to implement. Although some existing magnetic crawling robots can automatically complete the detection of the entire circumference, the magnetic crawling robots are relatively expensive, the volume height is relatively large, and they can only be used on metal magnetic pipelines, and are powerless against non-metallic non-magnetic pipelines. Summary of the invention

[0004] In view of this, the present application is committed to providing a magnetostrictive guided wave detection probe auxiliary device and an application method. The magnetostrictive guided wave detection probe auxiliary device is mainly composed of three parts: a probe clamping mechanism, a belt, and a belt driving mechanism. The problem that the magnetostrictive guided wave detection probe is difficult to completely travel around the circumference of a large pipeline with limited space or when the pipeline is very close to the ground, wall, etc. is solved.

[0005] The first aspect of the present application provides a magnetostrictive guided wave detection probe auxiliary device, which includes a belt, a probe clamping mechanism and a belt driving mechanism. The belt is mounted on the belt driving mechanism, and the belt is used to bind the magnetostrictive guided wave detection probe to the circumferential outer wall of the pipeline, so that the magnetostrictive guided wave detection probe is located between the belt and the circumferential outer wall of the pipeline. The probe clamping mechanism is used to cooperate with the magnetostrictive guided wave detection probe.

The passive tensioning module is fixed on the support arm. The support arm is connected to the probe clamping mechanism. The passive tensioning module is used to assist in the tensioning of the belt.

[0011] In a specific embodiment of the present application, a handle and a driven wheel are provided on the passive tensioning module. The handle is used to drive the passive tensioning module to extend when pulled, and to drive the passive tensioning module to automatically retract to its original state after being released. The belt is used to pass through the belt drive mechanism.

[0012] In a specific embodiment of the present application, the belt tensioning mechanism further includes an active tensioning module. The support arm and the active tensioning module are connected to each other via a rotating shaft. The active tensioning module has a built-in force sensor, which is used to sense the tension on the belt and adjust the height of the belt driving mechanism according to the tension on the belt to achieve active control of the belt tension.

[0013] In a specific embodiment of the present application, the belt has multiple length specifications.

[0014] The second aspect of the present application provides an application method of a magnetostrictive waveguide detection probe auxiliary device, the application method comprising: connecting a magnetostrictive waveguide detection probe using a probe clamping mechanism in the magnetostrictive waveguide detection probe auxiliary device provided in an embodiment of the present application; wrapping a belt in the magnetostrictive waveguide detection probe auxiliary device around the outer wall of a pipeline and fastening it; placing the magnetostrictive waveguide detection probe auxiliary device and the magnetostrictive waveguide detection probe against the outer wall of the pipeline, and using a belt to tie the magnetostrictive waveguide detection probe auxiliary device and the magnetostrictive waveguide detection probe to the outer wall of the pipeline. The belt is mounted on a belt drive mechanism; the belt drive mechanism is started to drive the magnetostrictive waveguide detection probe to move along the circumferential outer wall of the pipeline.

Therefore, the structure of the magnetostrictive waveguide detection probe auxiliary device is smaller, and is not limited by whether the pipeline is magnetic, and is not picky about the material of the pipeline.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] At least one embodiment of the present application provides a magnetostrictive guided wave detection probe auxiliary device, referring to Figure 7 and Figure 8 The magnetostrictive waveguide detection probe auxiliary device is used to be mounted on the magnetostrictive waveguide detection probe 8. Figure 1 and Figure 8As shown, the magnetostrictive guided wave detection probe auxiliary device includes a belt 2, a probe clamping mechanism and a belt driving mechanism. The belt 2 is mounted on the belt driving mechanism, and the belt 2 is used to bind the magnetostrictive guided wave detection probe 8 to the circumferential outer wall of the pipeline 9, so that the magnetostrictive guided wave detection probe 8 is located between the belt 2 and the circumferential outer wall of the pipeline 9. The probe clamping mechanism is used to cooperate with the magnetostrictive guided wave detection probe 8. The belt driving mechanism is used to provide a driving force to drive the magnetostrictive guided wave detection probe 8 on the belt 2 to move in the circumferential direction of the pipeline 9.

[0027] According to the technical solution provided in the embodiment of the present application, the magnetostrictive waveguide detection probe auxiliary device is mainly composed of three parts: a belt 2, a probe clamping mechanism and a belt driving mechanism. The magnetostrictive waveguide detection probe 8 is clamped by the probe clamping mechanism, and the magnetostrictive waveguide detection probe 8 is pressed against the outer wall of the pipeline 9 by the belt 2. Then, the magnetostrictive waveguide detection probe 8 is driven by the belt driving mechanism to move at a uniform speed on the outer wall of the pipeline 9, so that the magnetostrictive waveguide detection probe 8 can be tightly attached to the surface of the pipeline 9 and can move completely and uniformly along the circumference of the pipeline 9, which is not affected by whether the material of the pipeline 9 is ferromagnetic, nor is it limited by the pipe diameter and the size of the space, and no additional intervention is required. The principle structure of the magnetostrictive waveguide detection probe auxiliary device is simple and compact, reliable and easy to implement, and low cost. Compared with manually pushing the probe, the magnetostrictive waveguide detection probe auxiliary device has better speed maintenance and is adaptable to more working conditions; compared with using a magnetic crawling robot probe, the overall height of the magnetostrictive waveguide detection probe auxiliary device equipped with the magnetostrictive waveguide detection probe 8 is equivalent to the height of the magnetostrictive waveguide detection probe 8, and the overall height is low, which does not affect the passability of the magnetostrictive waveguide detection probe 8. Therefore, the structure of the magnetostrictive waveguide detection probe auxiliary device is more compact, and is not limited by whether the pipe 9 is magnetic, and is not picky about the material of the pipe 9.

[0028] The material of the belt 2 can be used as long as it can restrain the magnetostrictive guided wave detection probe 8 on the circumferential outer wall of the pipe 9 and does not affect the movement of the magnetostrictive guided wave detection probe 8. On this basis, the embodiment of the present application does not specifically limit the material of the belt 2. For example, in at least one embodiment of the present application, the belt 2 is a belt-shaped object made of rubber material, and the belt 2 is configured so that the two ends are connected to each other to form a ring. In this way, by setting the belt 2 as a belt-shaped object made of rubber material, the belt 2 has both flexibility and rigidity. After the belt 2 is put on the pipe 9, the magnetostrictive guided wave detection probe 8 and the magnetostrictive guided wave detection probe auxiliary device are installed in the gap between the belt 2 and the pipe 9.

[0029] The probe clamping mechanism only needs to be able to clamp the magnetostrictive waveguide detection probe 8. On this basis, the embodiment of the present application does not specifically limit the structural composition of the probe clamping mechanism. For example, in at least one embodiment of the present application, the probe clamping mechanism is mainly composed of two fastening screws 6 and two clamping bases 7. Figure 2 , Figure 6 and Figure 7 The clamping base 7 is provided with a first through hole 71 for the fastening screw 6 to pass through and a block-shaped protrusion 72 adapted to the second through hole 84 on the magnetostrictive guided wave detection probe 8. In this way, when in use, the block-shaped protrusions 72 of the two clamping bases 7 are inserted into the second through hole 84 on the magnetostrictive guided wave detection probe 8, and then the fastening screw 6 is inserted and fastened, so that the magnetostrictive guided wave detection probe auxiliary device is fixed on the magnetostrictive guided wave detection probe 8.

[0030] Specifically, refer to Figure 6 and Figure 7 The fastening screw 6 is mainly composed of a screw 61 and a nut 62, and the magnetostrictive guided wave detection probe 8 is mainly composed of a coil 81, a running wheel 82 and an arch frame 83. The magnetostrictive guided wave detection probe 8 is in the shape of a round arch bridge, and the arch frame 83 is provided with a second through hole 84 and a third through hole 85, the second through hole 84 is larger than the third through hole 85, and the clamping base 7 is provided with a block protrusion 72 adapted to the second through hole 84. Before installing the magnetostrictive guided wave detection probe auxiliary device, first disassemble the probe clamping mechanism, that is, remove the nut 62 of the fastening screw 6, and separate the two clamping bases 7; then install the magnetostrictive guided wave detection probe auxiliary device, that is, pass the screw 61 through the second through hole 84 on the arch frame 83, and insert the block protrusion 72 into the second through hole 84, then install the other clamping base 7, pass the first through hole 71 on the other clamping base 7 on the screw 61, and insert the block protrusion 72 into the second through hole 84 on the other side, then screw the nut 62 onto the screw 61 and tighten it in sequence. After tightening, the installation is completed, and the magnetostrictive guided wave detection probe 8 and the magnetostrictive guided wave detection probe auxiliary device form a whole, so that there will be no loosening, deflection, slippage and other phenomena.

[0031] In at least one embodiment of the present application, the belt drive mechanism includes two drive wheels 1. The two drive wheels 1 have independent speed control, so that the rotation speeds of the two drive wheels 1 are not affected by each other.

[0032] It should be noted that the driving wheel 1 can be driven by a battery, and the battery can be replaced. The driving wheel 1 can be arranged on the support arm 3.

[0033] In at least one embodiment of the present application, the magnetostrictive guided wave detection probe auxiliary device further includes a gyroscope. The gyroscope is used to sense and control the rotation speed of the two driving wheels 1 respectively, so as to ensure that the magnetostrictive guided wave detection probe 8 remains on the same cross-section of the pipeline 9 during its travel. In this way, the magnetostrictive guided wave detection probe 8 is ensured not to deviate during its travel on the outer wall of the pipeline 9 by the built-in gyroscope of the magnetostrictive guided wave detection probe auxiliary device.

[0034] In at least one embodiment of the present application, the magnetostrictive guided wave detection probe auxiliary device further includes a belt tightening mechanism. The belt tightening mechanism is connected to the belt 2 and is used to tighten the belt 2. In this way, tightening the belt 2 by the belt tightening mechanism can be more conducive to the transmission of the belt 2.

[0035] In at least one embodiment of the present application, Figure 1 and Figure 4 As shown, the belt tensioning mechanism includes a support arm 3 and a passive tensioning module 5. The passive tensioning module 5 is fixed on the support arm 3. The support arm 3 is connected to the probe clamping mechanism. The passive tensioning module 5 is used to assist in tightening the belt 2.

[0036] It should be noted that the support arm 3 and the clamping base 7 are connected to each other via a rotating shaft.

[0037] In at least one embodiment of the present application, Figure 3 As shown, the passive tensioning module 5 is provided with a handle 51 and a driven wheel 52. The handle 51 is used to extend the passive tensioning module 5 when it is pulled, and the passive tensioning module 5 automatically shrinks back to its original state after it is released. The belt 2 is used to pass through the driving wheel 1 in the belt drive mechanism. In this way, when the handle 51 is pulled, the passive tensioning module 5 is extended, and when the handle 51 is released, the passive tensioning module 5 automatically shrinks back to its original state. When the magnetostrictive guided wave detection probe auxiliary device is fixed, the belt 2 passes through the driving wheel 1. At this time, the passive tensioning module 5 is pulled again, and the driven wheel 52 is also pressed on the belt 2, so that the belt 2 is tightened multiple times.

[0038] In at least one embodiment of the present application, Figure 1 and Figure 4 As shown, the belt tensioning mechanism also includes an active tensioning module 4. The support arm 3 and the active tensioning module 4 are connected to each other through a rotating shaft. The active tensioning module 4 has a built-in force sensor, which is used to sense the tension on the belt 2 and adjust the height of the belt driving mechanism according to the tension on the belt 2 to achieve active control of the tension of the belt 2. In this way, the active tension control of the active tensioning part can be used to sense the tension on the belt 2 in real time and adjust the height of the driving wheel 1 according to the different tensions on the belt 2.

[0039] It should be noted that the support arm 3, the clamping base 7 and the active tensioning module 4 bracket are connected to each other through a rotating shaft. When the active tensioning module 4 is extended, the angle between the support arm 3 and the clamping base 7 also increases, and the belt 2 is tightened; when the active tensioning module 4 is contracted, the angle between the support arm 3 and the clamping base 7 decreases, and the belt 2 is loosened. The active tensioning module 4 has a built-in force sensor, which can be extended and contracted in real time according to the tension on the belt 2. The active tensioning modules 4 on both sides are independent of each other when adjusted.

[0040] The number of belts 2 can be one or more, and the embodiment of the present application does not specifically limit this. For example, in at least one embodiment of the present application, the belt 2 has multiple length specifications. In this way, by arranging each set of magnetostrictive guided wave detection probe auxiliary device to be equipped with belts of multiple length specifications, such as Figure 5 As shown, the length of the belt 2 can be adjusted by buckling according to the diameter of the pipe 9, and multiple belts 2 can also be used to form a long combined belt for large pipes.

[0041] At least one embodiment of the present application further provides an application method of a magnetostrictive guided wave detection probe auxiliary device, and the application method of the magnetostrictive guided wave detection probe auxiliary device includes the following steps.

[0042] S1: Connect the magnetostrictive guided wave detection probe 8 using the probe clamping mechanism in the magnetostrictive guided wave detection probe auxiliary device provided in the embodiment of the present application.

[0043] S2: Wrap the belt 2 in the magnetostrictive guided wave detection probe auxiliary device around the outer wall of the pipeline 9 and fasten it.

[0044] S3: The magnetostrictive waveguide detection probe auxiliary device and the magnetostrictive waveguide detection probe 8 are attached to the outer wall of the pipe 9, and the magnetostrictive waveguide detection probe auxiliary device and the magnetostrictive waveguide detection probe 8 are bound to the outer wall of the pipe 9 using the belt 2. The belt 2 is mounted on the belt drive mechanism.

[0045] S4: Start the belt drive mechanism to drive the magnetostrictive guided wave detection probe 8 to move along the circumferential outer wall of the pipeline 9.

[0046] For example, if Figure 6 As shown, when the magnetostrictive waveguide detection probe auxiliary device is used, the magnetostrictive waveguide detection probe auxiliary device is first installed on the magnetostrictive waveguide detection probe 8 (corresponding to step S1). Then, two belts 2 of appropriate length are selected, wrapped around the outer wall of the pipe 9, and adjusted to an appropriate length, and fastened and fixed, as shown in FIG. Figure 8As shown (corresponding to step S2). After the belt 2 is placed, the magnetostrictive guided wave detection probe auxiliary device and the magnetostrictive guided wave detection probe 8 are placed against the outer wall of the pipe 9, and the belt 2 is used to bind them to the outer wall of the pipe 9. The belt 2 is mounted in the groove on the driving wheel 1, and the driven wheel 52 is used to press the belt 2 (corresponding to step S3).

[0047] At this time, the magnetostrictive guided wave detection probe 8 is started for trial operation. Under the action of the belt tensioning mechanism, the height of the two driving wheels 1 is automatically adjusted first, so that the tension on the two belts 2 is kept consistent. After the tension is consistent, the two driving wheels 1 begin to rotate, driving the magnetostrictive guided wave detection probe 8 to move on the outer wall of the pipeline 9 (corresponding to step S4). The magnetostrictive guided wave detection probe auxiliary device has a built-in gyroscope, and the rotation speed of the two driving wheels 1 is controlled by the induction of the gyroscope to ensure that the magnetostrictive guided wave detection probe 8 remains on the same cross-section during the movement, thereby ensuring that the detection coil is always close to the magnetostrictive sheet on the outer wall of the pipeline 9. After one circle, if the movement trajectory of the magnetostrictive guided wave detection probe 8 remains within the expected range, the magnetostrictive guided wave detection probe 8 can be connected to the host to start detection. If the movement trajectory does not remain within the expected range, the position of the belt 2 can be appropriately adjusted until it meets expectations.
