Description

Technical Field

[0001] This invention belongs to the field of flaw detection equipment technology, and in particular relates to a flexible digital X-ray inspection device. Background Technology

[0002] During long-term service, pipeline welds are prone to leakage and breakage risks due to defects, which directly affect the safe operation of equipment. Radiographic testing can penetrate the pipe wall and weld, clearly revealing internal defects such as pores, cracks, and incomplete penetration. It provides a reliable basis for pipeline quality acceptance and in-service safety assessment, and is an important means of inspecting the quality of industrial pipeline welds.

[0003] Existing radiographic testing of pipeline welds mostly employs a double-wall single-image radiographic method. X-rays emitted by the X-ray source penetrate the pipe walls and weld on both sides, and are received and imaged by the detector on the opposite side. This allows for the identification of defects such as porosity, cracks, and incomplete penetration within the weld, providing a basis for pipeline quality acceptance and safety assessment. However, traditional rigid detectors can only perform single-point detection and require multiple adjustments, resulting in low efficiency. While flexible detectors can conform to the curved surface of the pipeline for single-point imaging, their flexible nature makes them susceptible to the influence of weld beads protruding from the weld, causing uneven stress and skewness. This leads to tilting and deflection relative to the pipe wall, resulting in blurred images, distorted defects, and reduced accuracy of interpretation. It can even lead to missed detections or misjudgments, failing to guarantee the reliability of the test results. Summary of the Invention

[0009] Preferably, the limiting component includes a rotating shaft fixed to the end of the take-up shaft, and the rotating shaft is rotatably connected to the end of the hollow box. The rotating shaft has a square groove inside, and a square shaft is slidably connected inside the square groove. A spring is fixed between the square shaft and the square groove. A rotating handle is fixed to the end of the square shaft away from the rotating shaft, and a pressure sleeve sleeved on the outside of the square shaft is fixed to the side wall of the rotating handle.

[0010] Preferably, a torque sensor is fixed to the outer side wall of the hollow box away from the rotating handle, and the rotating end of the torque sensor is connected to the shaft end of the winding shaft. The torque sensor is electrically connected to the receiving host.

[0011] Preferably, the adjustable support unit includes a U-shaped support plate, and the end of the U-shaped support plate slides through the side wall of the mounting block.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-6 As shown, a flexible digital X-ray inspection device includes a mounting block 1, an X-ray source 2, and a receiver 3. The X-ray source 2 is detachably connected to the mounting block 1. The device also includes a flexible receiver 4, which is electrically connected to the receiver 3. The flexible receiver 4 is located at the emission end of the X-ray source 2 and mainly includes a flexible X-ray sensing panel, a scintillation crystal layer, and a photoelectric conversion chip array. The flaw detection X-rays emitted by the X-ray source 2 penetrate the pipe wall and weld seam, and then enter the scintillation crystal layer, converting the invisible X-ray radiation signal into a visible light signal. The visible light signal is transmitted to the photoelectric conversion chip array, completing the conversion of the optical signal into an analog electrical signal. The weak electrical signal is amplified by the signal amplification circuit module and then sent to the analog-to-digital conversion module to convert the analog electrical signal into a digital signal. The receiver 3 uploads the digital signal to a computer for imaging display.

[0021] A flexible protective shell 5 is fixedly fitted onto the outside of the flexible receiver 4, and the receiver host 3 is fixedly connected to the outer wall of the flexible protective shell 5. The outer side of the flexible protective shell 5 has several tooth-like protrusions to increase radial strength and prevent excessive stress during encirclement. It is made of flexible plastic material with an IP67 protection rating. Several evenly distributed slots 6 are fixedly inserted into the inner arc edge of the flexible protective shell 5. Each slot 6 has a stop block 7 fixed at its opening. A movable block 8 is slidably connected inside the slot 6. A push rod 9 is fixed to the surface of the movable block 8. A through hole matching the push rod 9 is opened on the surface of the stop block 7. A ball is provided at the end of the push rod 9 to reduce wear on the end of the push rod 9. The inside of the slot 6 has a corresponding hole matching the movable block 8. 8. Matching electromagnetic pushing mechanism 10. Electromagnetic pushing mechanism 10 includes an electromagnetic component 101 fixed inside the slot block 6. A permanent magnet 102 is fixed at one end of the movable block 8 near the electromagnetic component 101. When the electromagnetic component 101 is energized, it generates a magnetic repulsion force on the permanent magnet 102. The electromagnetic component 101 is electrically connected to the receiver host 3. The slot block 6 is equipped with a ranging component 13. When the receiver host 3 starts the electromagnetic component 101, the current intensity of the electromagnetic component 101 is gradually increased by controlling the sliding rheostat, so that the magnetic repulsion force between the electromagnetic component 101 and the permanent magnet 102 can be gradually increased to adapt to different degrees of deflection. The slot block 6 and the movable block 8 are both made of electromagnetic shielding material to avoid affecting the normal operation of the flexible receiver 4, etc.

[0022] The ranging assembly 13 includes an electro-optical ranging probe 131 fixed inside the slot block 6. A reflector block 132 is fixed at one end of the movable block 8 near the electro-optical ranging probe 131. The receiving host 3 controls the corresponding electromagnetic component 101 to work according to the electrical signal fed back by the electro-optical ranging probe 131. The light beam emitted by the electro-optical ranging probe 131 is reflected by the reflector block 132 to the receiving end of the electro-optical ranging probe 131. By calculating the time required for the emitted light beam to reach the received light beam, the distance between the electro-optical ranging probe 131 and the movable block 8 can be measured. An electromagnetic shielding sleeve is fitted on the outside of the electro-optical ranging probe 131 to prevent the electromagnetic component 101 from affecting the normal operation of the electro-optical ranging probe 131.

[0023] The binding unit 11 is installed on the side wall of the mounting block 1, and the mounting block 1 is connected to the flexible protective shell 5 through the binding unit 11. The binding unit 11 includes two hollow boxes 111 fixed to the side wall of the mounting block 1, and the hollow boxes 111 are respectively arranged on both sides of the radiation source 2. A winding shaft 112 is rotatably provided inside the hollow box 111, and a pull strap 113 is wound around the winding shaft 112. The end of the pull strap 113 away from the winding shaft 112 slides through the side of the hollow box 111. Both ends of the flexible protective shell 5 are fixed with connecting straps 114. The end of the pull strap 113 away from the winding shaft 112 is connected to the connecting strap 114 on the same side through a separable buckle 115. The buckle 115 includes a male head and a female head. After the male head is inserted into the female head, the elastic support member on its side wall extends out from the through groove on the side wall of the female head to complete the snapping of the male head and the female head. When separation is required, the elastic support member on the side wall of the male head is pressed into the female head, and then the male head can be pulled out directly.

[0024] A limiting assembly 14 is installed on the take-up shaft 112. The limiting assembly 14 includes a rotating shaft 141 fixed to the end of the take-up shaft 112, and the rotating shaft 141 is rotatably connected to the end of the hollow box 111. A square groove 142 is formed inside the rotating shaft 141, and a square shaft 143 is slidably connected inside the square groove 142. A spring 144 is fixed between the square shaft 143 and the square groove 142. A handle 145 is fixed to the end of the square shaft 143 away from the rotating shaft 141, and a sleeve on the side wall of the handle 145 is fixed to the square shaft 143. The outer pressure sleeve 146 has its end abutting against the end of the hollow box 111. The end of the pressure sleeve 146 is provided with an annular anti-slip protrusion. The end face of the hollow box 111 and the pressure sleeve 146 opposite each other is provided with a matching annular frosted anti-slip surface to ensure that the frictional resistance after the hollow box 111 and the pressure sleeve 146 abut against each other is large enough. Through the contact between the pressure sleeve 146 and the hollow box 111, the handle 145 can be prevented from rotating at will, thereby ensuring the stable winding of the winding shaft 112 and the pull belt 113.

[0025] A torque sensor 15 is fixed to the outer wall of the hollow box 111 at the end away from the handle 145. The rotating end of the torque sensor 15 is connected to the shaft end of the take-up shaft 112. The torque sensor 15 is electrically connected to the receiver 3. The torque sensor 15 can monitor the torque when the take-up shaft 112 rotates. When the torque reaches the set value, it feeds back an electrical signal to the receiver 3. At this time, the rotation of the take-up shaft 112 can be stopped to avoid the pull belt 113 from being over-wound, causing the flexible receiver 4 to be overstretched.

[0026] The adjustable distance support unit 12 is installed on the side wall of the mounting block 1. The adjustable distance support unit 12 includes a U-shaped support plate 121, and the end of the U-shaped support plate 121 slides through the side wall of the mounting block 1. Rubber support pads 122 are fixed at both ends of the U-shaped support plate 121. A locking assembly 16 is installed on the side wall of the mounting block 1, and the mounting block 1 is relatively fixed to the U-shaped support plate 121 through the locking assembly 16. The distance between the mounting block 1 and the pipe can be adjusted through the U-shaped support plate 121, so that the distance between the radiation source 2 and the pipe can be adjusted according to the pipe with different diameters. The rubber support pads 122 can increase the tightness of the fit between the U-shaped support plate 121 and the outer wall of the pipe and improve the stability of the U-shaped support plate 121 abutting.

[0027] The locking assembly 16 includes a connecting block 161 fixed to the side wall of the mounting block 1. A stud 162 is fixed to the side wall of the connecting block 161. A strip hole 163 matching the stud 162 is opened on the side wall of the U-shaped support plate 121, and one end of the stud 162 passes through the strip hole 163. A crimp nut 164 is threaded onto the stud 162, and the side wall of the crimp nut 164 abuts against the side wall of the U-shaped support plate 121. After the crimp nut 164 is tightened, the connection strength between the U-shaped support plate 121 and the connecting block 161 can be ensured, and the U-shaped support plate 121 cannot slide freely on the side wall of the mounting block 1, thus ensuring support stability.

[0028] The operating principle of the present invention is explained as follows: When installing the entire device, separate the male and female heads of the buckle 115 on one side, then loosen the two crimp nuts 164 and move the U-shaped support plate 121. After adjusting the U-shaped support plate 121 to a suitable position, tighten the crimp nuts 164 again. By adjusting the position of the U-shaped support plate 121, the distance between the X-ray source 2 and the pipe weld can be adjusted (the distance between the X-ray source 2 and the pipe weld is usually maintained in the range of 200mm-400mm). Then, abut the rubber support pad 122 of the U-shaped support plate 121 against the outer wall of the pipe and align the X-ray source 2 with the weld. Then, the connecting strap 114 at one end of the detached buckle 115 is wrapped around the pipe, so that the entire flexible protective shell 5 and flexible receiver 4 surround the outside of the pipe. Next, the detached buckle 115 is re-secured. Then, the handle 145 is pulled outward to separate the pressure sleeve 146 from the hollow box 111. The handle 145 is rotated, and the handle 145 drives the winding shaft 112 to rotate through the square shaft 143, square groove 142 and rotating shaft 141. The winding shaft 112 can then wind the pull strap 113, thereby tightening the flexible protective shell 5 through the pull strap 113, buckle 115 and connecting strap 114, so that the flexible receiver 4 is tightly attached to the pipe weld. When the flexible protective shell 5 is pulled tight enough, the resistance to the rotation of the winding shaft 112 increases. At this time, the torque sensor 15 will detect that the torque reaches 10N. When m, the torque sensor 15 will immediately send an electrical signal to the receiver 3, and the receiver 3 will issue a voice prompt. At this time, stop rotating the handle 145 and press the handle 145 back so that the pressure sleeve 146 and the end of the hollow box 111 are back against each other. The friction between the end of the pressure sleeve 146 and the hollow box 111 can prevent the winding shaft 112 from rotating randomly. Then connect the X-ray source 2 and the receiver 3 to the external computer and power supply. At this point, the connection between the entire device and the pipeline is completed. Then, the receiver host 3 is activated, which controls the operation of each photoelectric ranging probe 131. The photoelectric ranging probe 131 emits a ranging beam, which is reflected by the reflector block 132 to the receiving end of the photoelectric ranging probe 131. By calculating the time required from emitting the ranging beam to receiving the reflected beam, the distance between the photoelectric ranging probe 131 and the movable block 8 can be measured. When the flexible receiver 4 is attached to the outside of the pipe weld, if the weld has no excess height and is flush with the outer wall of the pipe, the flexible receiver 4 will be tightly attached to the outer wall of the pipe and the surface of the weld. During the attachment process, the outer wall of the pipe simultaneously abuts against the end of the push rod 9, driving the push rod 9 to retract into the groove block 6, thereby ensuring that the flexible receiver 4 can be tightly attached to the outer wall of the pipe. When the weld has excess height, that is, the surface of the weld bulges outward after forming and is higher than the reference surface of the outer wall of the pipe, After the flexible receiver 4 is attached to the weld, a gap will be formed between the position of the flexible receiver 4 on both sides of the weld and the pipe. At this time, the end of the push rod 9 abuts against the outer wall of the pipe. Under the premise that the weld is formed regularly, the flexible receiver 4 remains horizontal. The gap between the two sides of the weld and the outer wall of the pipe is consistent, and the extension distance of the push rod 9 on both sides is also the same. The detection distance values ​​between the two photoelectric ranging probes 131 and the movable block 8 are equal. However, when there are irregular welding protrusion defects such as weld beads in the weld, the abnormal protrusion of the weld beads will push against the inner side of the flexible receiver 4, causing the flexible receiver 4 to be tilted laterally. After the tilt, the gap between one side of the flexible receiver 4 and the pipe decreases, and the gap on the other side increases. This causes the extension distance of the push rod 9 on one side to decrease, and the extension distance of the push rod 9 on the other side to increase. Ultimately, this causes the detection distance of the photoelectric ranging probe 131 at the corresponding position to deviate. If the distance deviation detected by the two photoelectric ranging probes 131 on opposite sides exceeds 1mm, the receiving host 3 will control the electromagnetic component 101 on the side with the smaller distance to operate, and gradually increase the current intensity flowing into the electromagnetic component 101. When the electromagnetic component 101 is energized, it will generate a magnetic repulsion force on the permanent magnet 102. At this time, because the push rod 9 is abutting against the outer wall of the pipe, the push rod 9 and the movable block 8 cannot move, and the electromagnetic component 101 will also be subjected to magnetic repulsion. Therefore, the electromagnetic component 101 will apply a force to one side of the flexible protective shell 5 away from the pipe through the slot block 6. The push force on the side increases the distance between the photoelectric ranging probe 131 on that side and the movable block 8 on the same side, and reduces the distance between the photoelectric ranging probe 131 on the other side and the movable block 8. When the distance deviation detected by the photoelectric ranging probes 131 on both sides is less than 1mm, the receiver host 3 controls the current intensity entering the electromagnetic component 101 to stop increasing, so that it can maintain the current intensity. This ensures that the two sides of the flexible receiver 4 are kept as balanced as possible, and avoids the flexible receiver 4 from being tilted, which would cause misalignment with the pipe weld and deviation of the X-ray detection optical path, affecting the detection accuracy. When the distance deviation detected by all photoelectric ranging probes 131 is within 1mm, the receiver host 3 issues a voice prompt. At this time, the X-ray source 2 can be activated. The X-ray source 2 emits X-rays that penetrate the pipe wall and weld area. The penetrated X-rays are received by the flexible receiver 4. The flexible receiver 4 converts the collected X-ray sensing signal into a digital electrical signal and transmits it to the receiver host 3. The receiver host 3 then uploads it to the computer, and finally displays the image information through the computer to complete the non-destructive testing of the pipe weld. After the test is completed, the male and female heads of the buckle 115 can be separated, and the entire device can be disassembled and removed from the outside of the pipe. Reference Figure 7-8 , Figure 7 The image shows the weld seam before the flexible receiver 4 was leveled. Figure 8 To obtain weld seam images after leveling the flexible receiver 4 using structures such as the push rod 9, and to compare them... Figure 7 and Figure 8 It can be seen that before the flexible receiver 4 was leveled, some areas had excessively deep shadows and the opposite side was overexposed, resulting in some pore defects not being displayed. Figure 8 The overall display maintains good balance and is well-displayed. Figure 7 Porous defects not visible in the middle.
