Description

Technical Field

[0001] The invention relates to the technical field of pipe flaw detection, in particular to a TA22 titanium alloy pipe flaw detection device. Background Art

[0002] Flaw detection of TA22 alloy (titanium alloy) pipes is a key inspection link to ensure their internal quality and performance. To ensure their quality and stability, flaw detection is required when the pipes are produced or after they have been used for a period of time. Pipe flaw detection is mainly used to detect defects such as cracks, pores, inclusions, and lack of fusion.

[0003] The flaw detection device currently used is in the form of a probe wirelessly connected to an instrument. In actual operation, the staff is required to place the probe against the outer wall of the pipeline and slide the probe around the pipeline for detection. This operation method is not only cumbersome, resulting in low detection efficiency, but also the flaw detection process is easily interfered by the external environment, which in turn affects the accuracy of the flaw detection results. Summary of the Invention

[0004] In view of the problems in the prior art that pipe flaw detection efficiency is low and the accuracy of flaw detection results is easily affected, the present invention provides a TA22 titanium alloy pipe flaw detection device.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a TA22 titanium alloy pipe flaw detection device, comprising a probe and a support frame, the support frame is rotatably connected to a convergence roller, the convergence roller is wound with a rubber layer, the rubber layer is provided with a slide groove, and the rubber layer is provided with symmetrically arranged limit grooves;

[0006] The rubber layer is provided with an isolation mechanism for isolating the external air, and the isolation mechanism includes a sealing rubber strip, a first Velcro, a second Velcro and a sealing airbag. There are two sealing rubber strips in total, and the sealing rubber strips are symmetrically fixedly connected to the rubber layer. The first Velcro is fixedly connected to the rubber layer at a position on one side of the slide groove. There are two second Velcros in total, and the second Velcro is symmetrically fixedly connected to the rubber layer at a position on one side of the first Velcro. One end of the sealing airbag is fixedly connected to a ventilation tube.

[0007] Specifically, a handle is fixedly connected to the side wall of the support frame, and the specific shape of the handle is C-shaped. The probes are fixedly connected with symmetrically arranged limit blocks, and the limit grooves are connected to the slide grooves. The probes are located inside the slide grooves, and the limit blocks are slidably connected to the corresponding limit grooves. The limit blocks are made of soft rubber.

[0008] Specifically, the support frame is provided with a limiting mechanism, and the limiting mechanism includes a first guide block and a second guide block. There are two first guide blocks in total, and a movable plate is slidably connected between the first guide blocks. A symmetrically arranged limiting ring is fixedly connected to one side of the movable plate, and a symmetrically arranged spring is fixedly connected to the other side of the movable plate. An extrusion plate is slidably connected to the second guide block.

[0009] Specifically, the first guide block is symmetrically fixedly connected to the support frame, the second guide block is fixedly connected to the side wall of the support frame, the specific shape of the first guide block is T-shaped, the specific shape of the second guide block is T-shaped, the other end of the spring is fixedly connected to the side wall of the support frame, the side wall of the extrusion plate is set in an inclined state, the inclined outer wall of the extrusion plate is abutted against the top corner of the movable plate, the specific shape of the limiting ring is a semi-ring setting, and the inner ring of the limiting ring is made of rubber.

[0010] Specifically, the first Velcro is configured as a hook surface, the second Velcro is configured as a suede surface, one end of the ventilation tube passes through the corresponding sealing rubber strip, and the ventilation tube is in communication with the sealing airbag.

[0011] Beneficial effects of the present invention:

[0012] According to the diameter of the pipe to be inspected, a rubber layer of appropriate length can be accurately released through the convergence roller. Subsequently, the corresponding number of probes can be installed in the rubber layer. Multiple probes can be evenly arranged in the rubber layer, realizing multi-probe synchronous inspection of the outer wall of the pipe, which significantly improves the inspection efficiency. The adjustable length of the rubber layer greatly enhances the applicability of the flaw detection device, making it flexible to adapt to the inspection requirements of different pipe diameters. In addition, the entire flaw detection device has a compact structure and is easy to carry, which provides great convenience for workers in outdoor operations.

[0013] The probe is tightly attached to the outer surface of the pipe through the isolation mechanism, forming a circular scanning path to ensure close contact between the probe and the pipe surface. Since the rubber layer and the isolation mechanism are soft-designed, the probe will not vibrate during the inspection process and has extremely strong stability, allowing the probe to maintain a stable inspection working state and avoid vibration affecting the inspection probe. In addition, external air cannot normally enter the rubber layer, effectively isolating it from external interference such as air, moisture and electromagnetic interference, reducing the degree of probe signal attenuation caused by air coupling, avoiding the influence of external factors on probe flaw detection, and improving the accuracy of defect identification and the accuracy of flaw detection results.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 6 , the present invention provides the following technical solutions:

[0024] Embodiment 1: A TA22 titanium alloy pipe flaw detection device includes a probe 1 and a support frame 2, the support frame 2 is rotatably connected to a focusing roller 3, a rubber layer 4 is rolled up on the focusing roller 3, a slide groove 5 is provided on the rubber layer 4, a symmetrically arranged limit groove 6 is provided on the rubber layer 4, and an isolation mechanism 7 for isolating from external air is provided on the rubber layer 4. The isolation mechanism 7 includes a sealing rubber strip 71, a first Velcro 72, a second Velcro 73 and a sealing airbag 74. There are two sealing rubber strips 71, which are symmetrically fixedly connected to the rubber layer 4, the first Velcro 72 is fixedly connected to the rubber layer 4 at a position on one side of the slide groove 5, and there are two second Velcros 73, which are symmetrically fixedly connected to the rubber layer 4 at a position on one side of the first Velcro 72. One end of the sealing airbag 74 is fixedly connected to a ventilation pipe 75;

[0025] A hand-held handle 8 is fixedly connected to the side wall of the support frame 2. The specific shape of the hand-held handle 8 is C-shaped. The probes 1 are all fixedly connected to symmetrically arranged limit blocks 9. The limit grooves 6 are all in communication with the slide grooves 5. The probes 1 are all located inside the slide grooves 5. The limit blocks 9 are all slidably connected to the corresponding limit grooves 6. The limit blocks 9 are made of soft rubber, the first Velcro 72 is set as a hook surface, and the second Velcro 73 is set as a suede surface. One end of the ventilation tube 75 passes through the corresponding sealing rubber strip 71, and the ventilation tube 75 is in communication with the sealing airbag 74;

[0026] During use, when flaw detection is performed on a pipe of corresponding diameter, a rubber layer 4 of corresponding length can be released through the convergence roller 3, and then the handheld probe 1 can be used to respectively insert the limit blocks 9 on the probe 1 into the corresponding limit grooves 6 through the deformable ability of the rubber layer 4. At this time, the probe 1 is located inside the chute 5. The number of probes 1 to be used is selected according to the diameter of the pipe. After the corresponding probes 1 are installed, the probes 1 can be pushed so that multiple probes 1 are evenly distributed inside the chute 5. The rubber layer 4 can be placed around the outer wall of the pipe to form a ring, and then the first Velcro 72 on the head end of the rubber layer 4 is attached to the two second Velcro 73, as shown in FIG. Figure 4 , the rubber layer 4 is fixed, and the sealing rubber strip 71 on the rubber layer 4 is tightly fitted with the outer wall of the pipe. At this time, the sealing airbag 74 is located at the connection position of the first Velcro 72 and the second Velcro 73. At this time, the vent tube 75 head can be opened, and then the sealing airbag 74 is inflated through the external inflation device. At this time, the gas will flow into the sealing airbag 74 through the vent tube 75. The expansion of the sealing airbag 74 will block the connection between the first Velcro 72 and the second Velcro 73, so that the external air cannot normally enter the chute 5 on the rubber layer 4, and then the vent tube 75 is closed. At this time, the support frame 2 can be held by the handheld handle 8 to rotate. The rotation of the rubber layer 4 on the pipe will drive the probe 1 to detect the outer wall of the pipe, and the same is true for the moving detection of the probe 1.

[0027] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 and includes: a limiting mechanism 10 is provided on the support frame 2, and the limiting mechanism 10 includes a first guide block 101 and a second guide block 102. There are two first guide blocks 101, and a movable plate 103 is slidably connected between the first guide blocks 101. A symmetrically arranged limiting ring 104 is fixedly connected to one side of the movable plate 103, and a symmetrically arranged spring 105 is fixedly connected to the other side of the movable plate 103. An extrusion plate 106 is slidably connected to the second guide block 102. The blocks 101 are symmetrically fixedly connected to the support frame 2, the second guide blocks 102 are fixedly connected to the side walls of the support frame 2, the specific shapes of the first guide blocks 101 are T-shaped, the specific shapes of the second guide blocks 102 are T-shaped, the other ends of the springs 105 are fixedly connected to the side walls of the support frame 2, the side walls of the extrusion plate 106 are inclined, the outer wall of the extrusion plate 106 is inclined and abuts against the top corner of the movable plate 103, the specific shapes of the limiting rings 104 are semi-annular, and the inner rings of the limiting rings 104 are made of rubber;

[0028] When in use, directly press the extrusion plate 106 downward with force, and the extrusion plate 106 moves downward and is guided by the second guide block 102. When the extrusion plate 106 is pressed down, its inclined outer wall will squeeze the movable plate 103, and the movement of the movable plate 103 will stretch the two springs 105. At the same time, the movement of the movable plate 103 will drive the two limit rings 104 to move toward the direction of the gathering roller 3. The movement of the movable plate 103 is guided by the first guide block 101. The limit ring 104 will contact the outer wall of the larger diameter position of the gathering roller 3 during the movement. At this time, the extrusion plate 106 is continuously pressed down, and the movable plate 1 03 will also drive the two limit rings 104 to move continuously. When the limit ring 104 moves, its inner ring will be squeezed against the outer wall of the position with a larger diameter of the focusing roller 3. At this time, the inner ring of the limit ring 104 will be deformed. When the outer wall of the extrusion plate 106 tilts and moves down to a position where it no longer squeezes the moving plate 103, the moving extrusion plate 106 can be stopped. At this time, the positions of the moving plate 103 and the extrusion plate 106 will be fixed due to the deformation of the inner ring of the limit ring 104. The limit ring 104 will also squeeze the focusing roller 3 to prevent the focusing roller 3 from rotating accidentally during the flaw detection process of the probe 1.
