Description

Technical Field

[0001] This invention relates to the field of ultrasonic nondestructive testing technology, and in particular to a multi-channel ultrasonic rotating probe. Background Art

[0002] With the continuous advancement of industrial automation, various industries are seeking more efficient and precise means of production and quality control. In particular, on continuous production lines for long and thin metal products such as steel bars and pipes, in order to ensure that product quality meets standards, a series of functional tests must be conducted on steel bars to detect whether there are internal defects or performance deficiencies. Against the backdrop of this functional testing, ultrasonic testing technology is gradually emerging and has become one of the indispensable key technologies.

[0003] Currently, most ultrasonic testing systems use a rotating single-probe design. The probe is placed in a specific position, and ultrasonic signals are emitted towards the object being tested by rotating the probe. When the ultrasonic waves propagate inside the object, if they encounter internal defects such as cracks, pores, or other discontinuous structures, the sound waves will be reflected, refracted, or scattered. The probe will receive the reflected signals and convert them into electrical signals. By analyzing the characteristics of these returned signals, the system can quickly determine whether there are defects inside the object, thus improving the efficiency of the testing.

[0004] Regarding the aforementioned technologies, when performing ultrasonic testing on steel bars, due to their shape and size characteristics, multiple rotational scans are typically required to complete a full circumferential inspection. In actual operation, the steel bars are continuously conveyed on the production line. In this situation, the probe's movement trajectory relative to the steel bar forms a spiral path on the outer side of the bar. This spiral scanning method makes it difficult to achieve full circumferential coverage of the steel bar, resulting in blind spots in the inspection. Furthermore, because the probe cannot uniformly cover the entire surface of the steel bar, internal defects or structural changes are difficult to fully capture, leading to a reduction in inspection accuracy. Summary of the Invention

[0005] To improve the detection accuracy of steel bars, this application provides a multi-channel ultrasonic rotating probe.

[0006] This application provides a multi-channel ultrasonic rotating probe, employing the following technical solution: A multi-channel ultrasonic rotating probe includes a body with a rotating frame rotatably connected to it. An adjustment disc is fixed to the outside of the rotating frame, and several probe seats are evenly distributed circumferentially along the adjustment disc and perpendicular to each other. Each probe seat contains a probe assembly, which is slidably connected to the probe seat along its length. Each probe assembly includes several probes. A detection cavity is formed within the body, with the probes facing each other. A rotating component is located on one side of the body to drive the rotating frame. Flow channel sleeves are located on both sides of the body, forming an annular water flow channel that communicates with the inner wall of the detection cavity. Two water inlet pipes are located at one end of the body, respectively on both sides, and communicate with the water flow channel. Couplers are located at both ends of the rotating frame to provide signals to the probes. Feed inlets are located at both ends of the body, with positioning components at each inlet for positioning a steel rod.

[0007] By adopting the above technical solution, water is supplied to the inlet pipe, and the water flows through the water channel to the detection chamber. The fluidity of the water allows it to quickly fill the gaps in the detection chamber, forming a stable coupling layer. This ensures that the ultrasonic waves emitted by the probe are efficiently transmitted into the steel bar being tested. The positioning component positions the bar, and the rotating component starts the rotating frame, which in turn rotates the probe seat. The probe seat rotates the probe assembly, which in turn rotates the probe assembly. Several probe seats are evenly distributed around the circumference of the adjustment disc and are perpendicular to each other, which expands the detection range. The probe assembly can slide along the length of the probe seat, making it easy to adjust the probe position. The rotation of the probe assembly drives the probe seat to rotate, and the probe is aligned with the detection chamber, allowing the probe to detect the steel bar inside the chamber. During the process of several probes rotating to detect the steel bar, the coupler allows the probe to continuously transmit signals while rotating, without the need for a cable that follows the rotation, ensuring stable signal transmission. This enables several probes to accurately detect the steel bar inside the detection chamber, improving the detection accuracy of the steel bar.

[0008] Optionally, both sides of the adjusting disk are provided with helical discs, which are rotatably connected to the adjusting disk. The outer edge of the helical disc is provided with gears, and the surface of the helical disc is provided with several helical grooves. Both sides of the probe assembly are fixed with slide rods. The surface of the probe seat is provided with a groove corresponding to the slide rod along the transverse direction. The slide rod is slidably connected to the probe seat along the length of the groove. The slide rod passes through the probe seat and is slidably connected to the helical disc along the length of the helical groove. The adjusting disk is provided with several adjusting wheels, which are evenly distributed around the circumference of the adjusting disk and mesh with the helical discs.

[0009] By adopting the above technical solution, a wrench is used to rotate the adjusting wheel, which in turn drives the gear to rotate, thereby driving the solenoid to rotate. The rotation of the solenoid causes the slide rod to move along the length of the thread groove. The groove limits the slide rod, allowing it to move along its length. The movement of the slide rod drives the probe assembly to move, thus achieving synchronous adjustment of the probe assembly. The movement of the probe assembly drives the movement of the probe, thereby changing the distance between the probe and the steel rod to adapt to different testing needs and improve the flexibility of probe use.

[0010] Optionally, the rotating components include a motor, a belt, and a turntable. The motor is located on one side of the machine body, the turntable is coaxially fixed with the motor output shaft, and the belt is located between the turntable and the rotating frame, and the belt is tactilely connected to both the turntable and the rotating frame.

[0011] By adopting the above technical solution, the motor starts and drives the turntable to rotate. The rotation of the turntable drives the rotating frame to rotate via the belt. The rotation of the rotating frame drives the adjusting plate to rotate. The rotation of the adjusting plate drives the probe seat to rotate. The rotation of the probe seat drives the probe assembly to rotate, which facilitates the probe to perform comprehensive testing on the steel bar and improves the convenience of using the probe.

[0012] Optionally, the positioning component includes a rotating handle, a threaded rod, several rotating blocks, and several guide wheels. The rotating handle is located at the upper end of the machine body. The threaded rod is fixed at one end of the rotating handle and is rotatably connected to the machine body. Several rotating blocks are evenly distributed along the circumference of the machine body and are rotatably connected to the machine body. Any rotating block is hinged to the threaded rod. The guide wheels correspond one-to-one with the rotating blocks and are fixed at one end of the rotating blocks. A hinge rod is provided between two adjacent rotating blocks and is hinged to the rotating blocks.

[0013] By adopting the above technical solution, rotating the handle causes the threaded rod to rotate, which in turn causes the connected rotating block to rotate. Adjacent rotating blocks are connected by hinged rods, enabling all rotating blocks to move synchronously. This, in turn, causes the guide wheels to move synchronously, allowing multiple guide wheels to simultaneously position the target object. This reduces the impact of steel rod jumping on the detection effect during the detection process and improves the stability of probe detection.

[0014] Optionally, an opening is provided on one side of the machine body, and an end cover is provided at the opening. The end cover is hinged to the machine body, and two connecting plates are fixed on the side of the end cover away from the machine body. The two connecting plates are located at both ends of the end cover, and the two connecting plates are bolted to the machine body.

[0015] By adopting the above technical solution, the end cover reduces the probability of dust and other particles entering the machine body through the opening. The opening is designed to facilitate the rotation of the adjustment wheel to adjust the position of the probe. The end cover is connected to the machine body by bolts through the connecting plate, making it easy to open the end cover to adjust the inside of the machine body, thus improving the stability of the device.

[0016] Optionally, the flow channel sleeve is provided with a sealing inner support, and positioning rings are fixed at both ends of the flow channel sleeve, with the positioning rings fitting in close contact with the sealing inner support.

[0017] By adopting the above technical solution, the inner sealing support fits with the positioning ring to form an axial compression seal. When the fluid in the flow channel generates pressure, the inner sealing support is squeezed and deformed, further filling the gap between the positioning ring and the flow channel cylinder, reducing water leakage in the detection chamber, and improving the sealing performance and stability of the equipment.

[0018] Optionally, a sealing ring is fixed between the probe holder and the probe assembly to reduce the probability of liquid leakage from the probe holder.

[0019] By adopting the above technical solution, the sealing ring seals the gap between the probe seat and the probe assembly, reducing the probability of water leakage from the probe during the detection process and improving the stability of the equipment.

[0020] Optionally, two mounting plates are fixed on one side of the machine body, with the two mounting plates located at both ends of the machine body respectively. The surface of the mounting plates is provided with a number of threaded holes, which are evenly distributed along the length of the mounting plates.

[0021] By adopting the above technical solution, two mounting plates are located at both ends of the machine body, providing multiple mounting support points for the machine body. Several threaded holes on the surface of the mounting plates are evenly distributed along the length direction, which allows the equipment to be installed in various ways by using bolts to engage with the threaded holes at different positions. This improves the flexibility of equipment installation according to the site space and installation requirements.

[0022] Optionally, a handle is fixed to the side of the machine body near the mounting plate, and the handle is used to move the machine body.

[0023] By adopting the above technical solution, the handle provides the operator with a convenient gripping point. When it is necessary to move the machine, the operator only needs to hold the handle to easily apply force to push or pull the machine, thus improving the convenience of using the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating frame rotates, causing the probe seat to rotate. The probe seat rotates, causing the probe assembly to rotate. The probe assembly rotates, causing the probe seat to rotate. The probe is aligned with the detection cavity, allowing the probe to detect the steel bar inside the detection cavity. During the process of several probes rotating to detect the steel bar, the coupler enables the probe to continuously transmit signals while rotating, without the need for a cable that follows the rotation. This ensures stable transmission of the detection signal, allowing several probes to accurately detect the steel bar inside the detection cavity and improving the detection accuracy of the steel bar. 2. The movement of the slide bar drives the movement of the probe assembly, thereby achieving synchronous adjustment of the probe assembly. The movement of the probe assembly drives the movement of the probe, thereby changing the distance between the probe and the steel rod to adapt to different detection needs and improve the flexibility of probe use. 3. The rotation of the handle drives the threaded rod to rotate, which in turn drives the connected rotating blocks to rotate. Adjacent rotating blocks are connected by hinged rods, enabling all rotating blocks to move synchronously. This, in turn, drives the guide wheels to move synchronously, allowing multiple guide wheels to simultaneously position the target object. This reduces the impact of steel rod jumping on the detection effect during the detection process and improves the stability of the probe detection. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a multi-channel ultrasonic rotating probe. Example

[0032] Reference Figure 1 and Figure 2A multi-channel ultrasonic rotating probe includes a body 1, a rotating frame 11 inside the body 1, and a detection cavity 13 inside the body 1. Flow channel sleeves 12 are provided at both ends of the rotating frame 11. The gap between the flow channel sleeves 12 and the rotating frame 11 forms an annular water flow channel 122, which is connected to the inner wall of the detection cavity 13. Two water inlet pipes 121 are provided at one end of the body 1, located on both sides of the body 1. When a steel bar is functionally tested, water is supplied to the water inlet pipes 121. The water flows along the water inlet pipes 121 to the water flow channel 122, and then through the water flow channel 122 to the detection cavity 13. The water fills the gaps in the detection cavity 13, forming a stable coupling layer to ensure that the ultrasonic waves emitted by the probe 1113 are transmitted into the steel bar under test.

[0033] Reference Figure 1 Both ends of the machine body 1 have feed inlets, and each feed inlet is equipped with a positioning element 14. The positioning element 14 includes a rotating handle 141, a threaded rod 142, several rotating blocks 143, and several guide wheels 144. The rotating handle 141 is located at the upper end of the machine body 1. The threaded rod 142 is fixed to one end of the rotating handle 141 and is rotatably connected to the machine body 1. Rotating the rotating handle 141 causes the threaded rod 142 to rotate. The several rotating blocks 143 are evenly distributed around the circumference of the machine body 1 and are rotatably connected to the machine body 1. Any rotating block 143 is hinged to the threaded rod 142. The guide wheels 144 are... Each rotating block 143 corresponds to a guide wheel 144 fixed at one end of the rotating block 143. A hinge rod 145 is provided between two adjacent rotating blocks 143. The hinge rod 145 is hinged to the rotating block 143. The rotation of the threaded rod 142 drives the rotating block 143 connected to it to rotate. Adjacent rotating blocks 143 are connected by the hinge rod 145, so that all rotating blocks 143 can move synchronously, thereby driving the guide wheel 144 to move synchronously. After the steel rod enters the machine body 1, multiple guide wheels 144 simultaneously position the steel rod, reducing the impact of the steel rod jumping on the detection effect during the detection process and improving the stability of the probe 1113 detection.

[0034] Reference Figure 1 and Figure 2 A motor 15 is fixedly mounted on the outside of the machine body 1. A turntable 151 is fixedly mounted on the output shaft of the motor 15. When the motor 15 starts, it drives the turntable 151 to rotate. A belt 152 is provided between the turntable 151 and the rotating frame 11. The belt 152 is tactilely connected to the turntable 151 and the rotating frame 11 respectively. The rotation of the turntable 151 drives the rotating frame 11 to rotate through the belt 152. An adjustment plate 111 is fixedly mounted on the outside of the rotating frame 11. The rotation of the rotating frame 11 drives the adjustment plate 111 to rotate. Several probe seats 1111 are provided in the adjustment plate 111. The probe seats 1111 are evenly distributed around the circumference of the adjustment plate 111 and are perpendicular to each other, thereby expanding the coverage area of ​​the probe 1113.

[0035] Reference Figure 2The adjustment disk 111 rotates, causing the probe seat 1111 to rotate. The probe seat 1111 contains several probe assemblies 1112. The adjustment disk 111 rotates, causing the probe assembly 1112 to rotate. The probe assembly 1112 contains several probes 1113. The rotation of the probe assembly 1112 causes the probes 1113 to rotate. The probe assembly 1112 slides along the length of the probe seat 1111, which facilitates the adjustment of the position of the probes 1113. The probes 1113 are directly opposite the detection chamber 13. The rotation of the probe assembly 1112 causes the probes 1113 to rotate. Couplers 19 are provided at both ends of the rotating frame 11. The several probes 1113 rotate to detect the steel rod. The couplers 19 enable the probes 1113 to continuously transmit signals while rotating, so as to ensure the stable transmission of the detection signal.

[0036] Reference Figure 3 An opening 16 is provided on one side of the body 1. The design of the opening 16 facilitates maintenance and other operations inside the body 1. An end cover 161 is provided at the opening 16. The end cover 161 is hinged to the body 1. The end cover 161 reduces the probability of dust and other particles entering the body 1 from the opening 16. Two connecting plates 162 are fixed on the side of the end cover 1 away from the body 1. The two connecting plates 162 are located at both ends of the end cover 161 and are bolted to the body 1. The end cover 161 is connected to the body 1 through the bolted connection of the connecting plates 162, which also facilitates opening the end cover 161 to adjust the inside of the body 1 and improves the stability of the device.

[0037] Reference Figure 4Both sides of the adjusting disk 111 are provided with helical disks 112, which are rotatably connected to the adjusting disk 111. Gears are provided on the outer edge of the helical disks 112. Several adjusting wheels 113 are provided inside the adjusting disk 111, evenly distributed around the circumference of the adjusting disk 111, and mesh with the helical disks 112. By opening the end cover 161 and using a wrench to rotate the adjusting wheels 113 through the opening 16, the rotation of the adjusting wheels 113 drives the adjusting disk 111 to rotate. Several helical grooves 1121 are formed on the surface of the helical disks 112. Slide rods 1115 are fixed on both sides of the probe assembly 1112. The probe seat 1111 has transverse grooves 1114 corresponding to the slide rods 1115 on its surface. 5. The slide rod 1115 is slidably connected to the probe seat 1111 along the length of the slide groove 1114. The slide rod 1115 passes through the probe seat 1111 and is slidably connected to the helical disc 112 along the length of the helical groove 1121. The rotation of the helical disc 112 causes the slide rod 1115 to move along the length of the threaded groove. The slide groove 1114 limits the slide rod 1115, causing the slide rod 1115 to move along the length of the slide rod 1115. The movement of the slide rod 1115 drives the probe assembly 1112 to move, thereby realizing the synchronous adjustment of the probe assembly 1112. The movement of the probe assembly 1112 drives the probe 1113 to move, thereby changing the distance between the probe 1113 and the steel rod to adapt to different detection needs and improve the flexibility of the probe 1113.

[0038] Reference Figure 1 Two mounting plates 17 are fixed on one side of the body 1. The two mounting plates 17 are located at both ends of the body 1. The body 1 provides multiple mounting support points. Several threaded holes 171 are opened on the surface of the mounting plates 17. The threaded holes 171 are evenly distributed along the length of the mounting plates 17. This allows the equipment to be installed in a variety of ways by using bolts to engage with the threaded holes 171 at different positions. This improves the flexibility of equipment installation according to the site space and installation requirements.

[0039] Reference Figure 2 The flow channel cylinder is equipped with a sealing inner support 123, and both ends of the flow channel sleeve 12 are fixed with positioning rings 124. The positioning rings 124 fit with the sealing inner support 123 to form an axial compression seal. When the fluid in the flow channel generates pressure, the sealing inner support 123 is squeezed and deformed, further filling the gap between the positioning rings 124 and the flow channel cylinder, reducing water leakage in the detection chamber 13, and improving the sealing performance and stability of the equipment.

[0040] Reference Figure 2A sealing ring 1116 is fixed between the probe holder 1111 and the probe assembly 1112. During the detection process, the machine body 1 will vibrate. The vibration may cause the gap between the probe holder 1111 and the probe 1113 to widen. The elastic properties of the sealing ring 1116 can absorb the vibration energy, reduce the impact of vibration on the connection part, maintain a good sealing state, reduce the probability of water leakage from the probe 1113 during the detection process, and improve the stability of the equipment.

[0041] Reference Figure 3 A handle 18 is fixed on the side of the machine body 1 near the mounting plate 17. The handle 18 provides an easy gripping point for the operator. When it is necessary to move the machine body 1, the operator can easily apply force by holding the handle 18 to push or pull the machine body 1, thereby improving the convenience of using the equipment.

[0042] The implementation principle of a multi-channel ultrasonic rotating probe according to an embodiment of this application is as follows: When performing functional testing on a steel rod, the positioning component 14 positions the steel rod entering the machine body 1. The end cover 161 is opened, and the adjusting wheel 113 is rotated from the opening 16. The rotation of the adjusting wheel 113 drives the solenoid 112 to rotate. The rotation of the solenoid 112 causes the probe assembly 1112 to slide along the length direction of the probe seat 1111, thereby adjusting the position of the probe 1113. After the adjustment is completed, the motor 15 is started to drive the turntable 151 to rotate. The rotation of the turntable 151 drives the rotating frame 11 to rotate through the belt 152. The rotation of the rotating frame 11 drives the adjusting plate 111 to rotate. The rotation of the adjusting plate 111 drives the probe seat 1111 to rotate. The rotation of the probe seat 1111 drives the probe 1113 to rotate, so that several probes 1113 can simultaneously detect the steel rod, achieving comprehensive coverage detection of the steel rod, reducing blind spots, and improving the detection accuracy of the steel rod.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
