Description

Technical Field

[0001] The present invention relates to the technical field of material detection, and in particular to a round rod phased array ultrasonic detection front surface cleaning device and its application. Background Art

[0002] Special steel round bars undergo rigorous quality inspections before leaving the factory. Internal quality is tested using automated ultrasonic testing using a partial water immersion method. During testing, the round bar passes through the ultrasonic testing equipment, and the ultrasonic field rotates around it, forming a spiral scan of the bar. The space between the ultrasonic probe and the round bar is filled with coupling water, through which ultrasonic waves are incident on the round bar. The instrument determines the internal quality of the round bar based on the ultrasonic echo signal from the round bar. The round bar has a black surface and is often covered with surface deposits such as scale and dust. These surface deposits are washed away by water immersion and remain in the ultrasonic testing chamber. Rotating with the coupling water, these deposits can easily lead to missed detections or false alarms. Furthermore, the erosion and fouling of the probe by residues in the coupling water accelerates performance degradation and shortens its life. Furthermore, the accumulation of residues in the ultrasonic chamber can clog components, making disassembly difficult and even damaging them. This is especially true in round-rod phased array ultrasonic testing equipment. Because multiple phased array probes are closely arranged along the axis and evenly spaced circumferentially around the center of the equipment, each probe scans a specific angular area. The curved surface of the ultrasonic probe is part of the cylindrical surface of the ultrasonic cavity. Rotationally coupled water residues can easily deposit on the probe surface, forming scale, damaging the probe's acoustically transparent layer and ultimately the probe wafer. This not only affects testing results, but also shortens the probe's lifespan and increases equipment operating costs.

[0003] In view of this, a surface pre-wetting cleaning device is usually added before ultrasonic testing. There is a circle of nozzles on the inner wall of the device that are evenly distributed in a circular shape and vertically spray the surface of the round rod. However, due to the large number of specifications of round rods, when pre-wetting the surface of round rods with different diameters, the distance between the nozzle and the round rod surface decreases as the diameter of the round rod increases. In addition, the center elevation and water pressure of the device need to be adjusted each time the specifications are changed, which increases the workload.

[0004] In view of this, this application is hereby filed. Summary of the Invention

Therefore, it should not be understood as a limitation on the present invention.

[0039] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0040] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0041] Please refer to Figures 1 to 6 As shown in the drawings, the embodiment provides a round bar phased array ultrasonic testing front surface cleaning device, which comprises a cylinder 100, one end of the cylinder 100 is provided with a mounting part for connecting with an ultrasonic device, and the other end of the cylinder 100 is provided with a first through hole for the round bar to pass through.

[0042] A end cover 101 is arranged outside the first through hole, a second through hole is arranged on the end cover 101, a rubber ring 200 is arranged between the end cover 101 and the cylinder 100, the center of the second through hole and the center of the rubber ring 200 are located on the axis of the cylinder 100, and the inner diameter of the rubber ring 200 is less than or equal to the hole diameter of the first through hole and the second through hole.

[0043] A water inlet pipe 401 and a drain 104 are arranged on the cylinder 100, and two or more nozzles 404 facing the round bar to be cleaned are arranged in the cylinder 100, and the water inlet pipe 401 and the nozzles 404 are connected through a live knot pipe 403.

[0044] In the embodiment, the one end of the cylinder 100 is provided with a mounting part for connecting with the ultrasonic device, and the specific form of the mounting part can be selected according to the needs, and a flange edge 105 can be selected, or a screw hole 103 is arranged to be installed on the ultrasonic device by a bolt 102; the other end of the cylinder 100 is provided with a first through hole, and the hole diameter of the first through hole needs to be greater than the diameter of the round bar so that the round bar can pass through smoothly. The end cover 101 is arranged on the first through hole, and the end cover 101 and the cylinder 100 can be connected through the screw hole 103 and the bolt 102, and the rubber ring 200 is further arranged between the end cover 101 and the cylinder 100, wherein the inner diameter of the rubber ring 200 is matched with the diameter of the round bar, and in general, the inner diameter of the rubber ring 200 can be slightly smaller than the diameter of the round bar, so as to preliminarily clean the surface of the round bar, but if the inner diameter of the rubber ring 200 is too small to match the diameter of the round bar, that is, the diameter of the round bar is too large to pass through the rubber ring 200, then different specifications of the rubber ring 200 need to be replaced according to the situation. In addition, the rubber ring 200 may have problems such as aging and excessive wear of the inner diameter after long-term use, and the rubber ring 200 needs to be replaced according to the situation.

[0045] After initial cleaning by rubber ring 200, the rod to be cleaned enters cylinder 100. Nozzle 404 within cylinder 100 sprays a pressurized water column to further clean the rod's surface. In this embodiment, nozzle 404 and water inlet pipe 401 are connected by a slipknot tube 403. This slipknot tube 403 is used to connect the rotating nozzle 404 and keep it stationary at a set position and angle. When the rod's diameter changes, to maintain the impact force of nozzle 404 on the rod's surface, there's no need to adjust the water pressure or pump. Adjustment is quick and easy, requiring only the degree of curvature of slipknot tube 403 to adjust the position and angle of nozzle 404.

[0046] After the round rod to be cleaned is rinsed by the nozzle 404 in the barrel 100, it leaves from the other end of the barrel 100 and enters the ultrasonic equipment for ultrasonication.

[0047] In this embodiment, the surface cleaning device before the round rod phased array ultrasonic detection can be installed in the drainage cavity at the end of the existing ultrasonic detection equipment 700, without having to consider increasing space. The disassembly and assembly operations can be carried out offline when the ultrasonic equipment is under maintenance. The operating space is not limited, the operation is simple, easy to use, safe and reliable, low cost, and economical.

[0048] In this embodiment, multiple nozzles 404 are installed within the cylinder 100. The distance between each nozzle 404 and the round rod and the spray angle can be adjusted as needed to achieve the best cleaning effect on the round rod surface. Improving the cleanliness of the coupled water in the ultrasonic cavity ensures the accuracy of ultrasonic testing, while reducing the frequency of ultrasonic cavity cleaning and improving the efficiency of steel detection.

[0049] This embodiment is easy to promote and apply, and can be applied to rotary ultrasonic testing of round rods, rotary ultrasonic testing of round tubes, and pre-wetting cleaning before phased array ultrasonic testing of round tubes. It can also be applied to cleaning surface attachments necessary in other operations on round rods and round tubes.

[0050] In some embodiments, an annular tube 400 communicating with the water inlet pipe 401 is provided in the cylinder 100 . Two or more pipe openings 402 are circumferentially provided on the annular tube 400 . The pipe openings 402 are connected to the inlet end of the slipknot tube 403 .

[0051] An annular tube 400 is provided which is connected to the water inlet pipe 401 , and a pipe opening 402 is provided on the annular tube 400 which is connected to the slipknot tube 403 . The annular tube 400 is used to distribute the flow of the nozzle 404 connected to the slipknot tube 403 . The structure is relatively simple and can save the length of the pipeline.

[0052] In this embodiment, in the initial state, the slipknot tube 403 and the nozzle 404 can be arranged along the radial direction of the annular tube 400. At this time, it can be used to clean round rods with the smallest relative diameter. As the diameter of the round rod to be cleaned increases, the slipknot tube 403 needs to be bent appropriately to shorten the distance between the nozzle 404 and the annular tube 400. At the same time, according to different round rod surface conditions or cleaning needs, the angle of the nozzle 404 can be adjusted. For example, the nozzle 404 can be selected to be perpendicular to the round rod surface or the nozzle 404 can be selected to have a certain angle with the round rod surface.

[0053] In some embodiments, six pipe openings 402 are evenly distributed along the circumference of the annular pipe 400 .

[0054] In some embodiments, when the diameters of the round rods to be cleaned differ greatly, the number of nozzles 402 can be increased; if necessary, the switch of the nozzle 404 can also be controlled in steps. For example, 12 nozzles 402 are distributed on the annular tube 400, and the 12 nozzles 402 are divided into two groups, with 6 in each group, and the nozzles 402 in the two adjacent groups are staggered. When in use: when the diameter of the round rod to be cleaned is small, only one group of nozzles corresponding to 6 nozzles 402 can be opened; when the diameter of the round rod to be cleaned is large, two groups of nozzles corresponding to 12 nozzles 402 can be opened to maintain the cleaning effect.

[0055] In some embodiments, the slipknot tube 403 is spherically connected to the nozzle 402 and the nozzle 404 to facilitate relative rotation between the slipknot tube 403 and the nozzle 402 .

[0056] In some embodiments, an annular tube gasket 500 is disposed in the cylinder 100 , and a groove having a shape and size matching that of the annular tube 400 is disposed on the annular tube gasket 500 .

[0057] The annular tube gasket 500 in this embodiment is interference fit with the cylinder 100 . The annular tube gasket 500 is located between the annular tube 400 and the cylinder 100 , and can limit, buffer and protect the annular tube 400 .

[0058] In some embodiments, a U-shaped cavity is provided between the end cover 101 and the cylinder 100 , the rubber ring 200 is installed in the U-shaped cavity, and a notch communicating with the U-shaped cavity is provided on the end cover 101 .

[0059] The U-shaped cavity in this embodiment is used to install the rubber ring 200, and the notch facilitates the replacement of the rubber ring 200. When the rubber ring 200 needs to be replaced, the rubber ring 200 can be directly pulled out from the notch, and then the replaced rubber ring 200 can be installed from the notch to the U-shaped cavity.

[0060] In this embodiment, the U-shaped cavity needs to be fixed to the rubber ring 200, so the thickness of the U-shaped cavity needs to be adapted to the thickness of the rubber ring 200.

[0061] In some embodiments, an auxiliary caliper 800 is further included for assisting in adjusting the position of the nozzle 404, as shown in Figure 7 and Figure 8 .

[0062] The auxiliary caliper 800 includes a radial measuring scale 810 that can be arranged along the diameter direction of the barrel 100, and the two ends of the radial measuring scale 810 are provided with mounting ears 820 that are adapted to the outer surface of the mounting part away from the axis of the barrel 100.

[0063] The radial measuring scale 810 is provided with an axial measuring scale 830 that can move along the radial measuring scale 810.

[0064] When it is necessary to adjust the position of the nozzle 404, the barrel 100 can be detached from the ultrasonic device, and then the auxiliary caliper 800 is mounted on the barrel 100. The mounting ears 820 at the two ends of the measuring scale have a certain curvature and length, and can be respectively adapted to the outer side of the mounting part, such as the flange edge 105, of the barrel 100, thereby playing a limiting role on the auxiliary caliper 800. At the same time, when it is necessary to adjust the nozzle 404 at different positions, the radial measuring scale 810 can also be rotated as needed to adjust the orientation of the radial measuring scale 810. The radial measuring scale 810 is provided with a scale, which can have 0 as the center and gradually increase towards the two ends, thereby facilitating the determination of the distance between the nozzle 404 and the axis of the barrel 100.

[0065] When the diameter of the round bar is too large, and the nozzle 404 needs to be inclined at a certain angle, the readings of the radial measuring scale 810 and the axial measuring scale 830 at the front and back ends of the nozzle 404 can be determined to determine the inclination angle of the nozzle 404.

[0066] In some cases, the nozzle 404 can also need to be arranged at an inclination angle in a direction perpendicular to the radial and axial directions. In this case, the auxiliary caliper 800 can also be provided with a radial measuring scale 810 and a fixed ring that is sleeved on the radial measuring scale 810 and can move along the radial measuring scale 810 but cannot rotate relative to the radial measuring scale 810. The fixed ring is provided with a movable ring that can rotate about the radial measuring scale 810. The movable ring is provided with a second measuring scale that is perpendicular to the radial measuring scale 810. The fixed ring can be provided with a scale, and the movable ring can be provided with an indicating line that indicates the angle through which the movable ring rotates relative to the fixed ring, thereby facilitating the adjustment of the angle of the nozzle 404 in each direction.

[0067] Another embodiment of the present application provides a round bar phased array ultrasonic detection device, as shown in Figures 1 to 8The device shown includes an ultrasonic device and a front surface cleaning device for round rod phased array ultrasonic testing as described in any one of the aforementioned embodiments.

[0068] In this embodiment, the drainage cavity provided by the ultrasonic device can be utilized and extended by the cylinder 100 , so that existing equipment can be utilized and easily modified.

[0069] In some embodiments, a flange edge 105 is provided at one end of the cylinder 100 away from the first through hole, and a pressing member 300 is provided on the ultrasonic device for pressing the flange edge 105 onto the ultrasonic device. The ultrasonic device includes a rod channel, and the rod channel is concentrically arranged with the rubber ring 200.

[0070] In some embodiments, a guide sleeve 600 is further provided between the flange edge 105 and the ultrasonic device. The guide sleeve 600 and the rubber ring 200 are coaxially arranged, and the inner diameters of the guide sleeve 600 and the rubber ring 200 are both adapted to the diameter of the round rod to be detected.

[0071] The position between the barrel 100 and the ultrasonic device is relatively fixed, and when detecting round rods of different diameters, there is no need to adjust the height and position of the barrel 100.

[0072] When using the phased array ultrasonic detection device for round rods in this embodiment, a rubber ring 200 and guide sleeve 600 of appropriate inner diameter are selected based on the specifications of the round rod to be tested. The ultrasonic detection device 700 is moved horizontally to the offline position, the clamping member 300 is loosened, and the barrel 100 is removed. Then, with the help of an auxiliary caliper 800, the position of the slipknot tube 403 and nozzle 404 of the movable nozzle is adjusted to ensure the appropriate distance and angle between the nozzle 404 and the surface of the round rod. The guide sleeves 600 at the inlet and outlet of the ultrasonic detection device 700 are replaced, and the rubber ring 200 at one end of the end cap 101 is replaced. The barrel 100 is reinstalled and fixed to the inlet of the ultrasonic detection device 700, and the water inlet pipe is connected. A solenoid valve automatically activates the water spray before the head of the round rod enters the device. The water spray continues to sweep the surface of the round rod as the round rod passes through, and the water spray automatically shuts off when the tail end of the round rod exits the device. The water spray is discharged from the device cavity through a drain pipe under the barrel 100 into the bottom tank of the ultrasonic device and flows to the filtration circulation device.

[0073] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention.
