Description

Technical Field

[0001] This utility model belongs to the field of non-destructive testing technology for welds, and particularly relates to a four-wheel magnetic memory detection probe with adjustable sensor. Background Technology

[0002] Welded structures are widely used in important fields related to national economy and people's livelihood, such as petrochemical, energy and power, and aerospace. Welded structures often operate under high temperature, high pressure and high corrosion conditions. If an accident occurs, it will cause great harm to our property and lives. Therefore, the inspection and accurate evaluation of welds are directly related to the safe operation of equipment. Four-wheel magnetic memory probes are used to perform non-destructive testing on welds.

[0003] Current four-wheel magnetic memory probes are mainly used to inspect planar areas, large-diameter container walls, and welds with relatively small reinforcement heights. However, these probes have significant shortcomings in practical applications: First, the design is not suitable for inspecting welds with a reinforcement height of 5mm, making it difficult to meet the requirements of domestic industry standards for weld reinforcement height inspection. Second, the sensor cannot be independently adjusted and cannot flexibly adapt to different workpiece surfaces. When faced with workpieces with complex and diverse surface conditions, the detection accuracy and adaptability are greatly limited. These shortcomings significantly reduce the efficiency and accuracy of the probes in actual inspection work, making it difficult to meet the ever-increasing inspection demands.

[0004] To address this issue, we propose a sensor-adjustable four-wheel magnetic memory detection probe. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art that it is inconvenient to detect welds with a height of 5mm and that it is inconvenient to independently adjust the sensor, and to propose a four-wheel magnetic memory detection probe with adjustable sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sensor-adjustable four-wheel magnetic memory detection probe includes an aluminum alloy shell. A detection probe body is snapped into the interior of the aluminum alloy shell. A detection arc groove is formed on the bottom surface of the detection probe body. Equally spaced limiting baffles are fixedly connected to the left side of the aluminum alloy shell. Equally spaced encapsulation shells are arranged on the left side of the aluminum alloy shell. The sides of the two sets of limiting baffles that are close to each other contact the front and back sides of several encapsulation shells, respectively. A probe sensor is slidably connected inside each encapsulation shell. An electric telescopic rod is fixedly connected to the upper surface of each encapsulation shell. The telescopic ends of several electric telescopic rods are fixedly connected to the upper surfaces of several probe sensors. An extension telescopic rod is fixedly connected to the upper surface of each electric telescopic rod. The end of each extension telescopic rod away from the electric telescopic rod is fixedly connected to the upper surface of the aluminum alloy shell. An adjustment groove is formed on the left side of each encapsulation shell. A fastening bolt is slidably connected inside each adjustment groove. The right ends of several fastening bolts contact the left sides of several probe sensors, respectively.

[0007] Preferably, the output end of the detection probe body is fixedly connected to two sets of extension rods, and each set of extension rods is fixedly connected to a sprocket at one end that is far apart from the other.

[0008] Preferably, each set of sprockets has a chain fitted on its outer surface, and an encoder is fixedly connected to the side of each set of sprockets that is far apart from each other.

[0009] Preferably, a probe communication connector is fixedly connected to the right side of the detection probe body, and the right end of the probe communication connector penetrates through the aluminum alloy shell and extends to the right side of the aluminum alloy shell.

[0010] Preferably, a rotating rod is fixedly connected to the inner wall of the detection probe body. The rotating rod is rotatably connected to the inside of the aluminum alloy shell. Two locking rods are fixedly connected to the outer surface of the rotating rod. The sides of the two locking rods that are close to each other are in contact with the front and back of the aluminum alloy shell, respectively.

[0011] Preferably, the left ends of the two locking diagonal rods are fixedly connected to a compression vertical plate, and a fixing rubber pad is provided on the right side of the compression vertical plate. The left side of each of the encapsulation shells is in contact with the right side of the fixing rubber pad.

[0012] Preferably, the right ends of the two locking diagonal rods are fixedly connected to a horizontal positioning plate, and the internal threads of the horizontal positioning plate are connected to a locking bolt. The bottom end of the locking bolt passes through the horizontal positioning plate and is connected to the internal threads of the aluminum alloy shell.

[0013] Preferably, both ends of the rotating rod away from the aluminum alloy shell are fixedly connected to baffles, and the side of the two baffles that are close to each other are in contact with the side of the two locking rods that are far from each other.

[0014] In summary, the technical effects and advantages of this utility model are as follows: By using an aluminum alloy shell around the main body of the detection probe, the aluminum alloy shell not only eliminates the risk of magnetic field shielding but also provides excellent protection for the internal sensor, preventing damage from external factors during use and improving the sensor's stability and lifespan. Furthermore, by utilizing the detection arc groove under the main body of the probe, the distance between the bottom arc surface of the probe and the roller is optimized from the original 4mm to 7mm. This optimization allows the probe to successfully complete the on-site detection of weld reinforcement heights of up to 5mm, meeting the requirements of domestic industry standards for weld reinforcement height detection. The probe sensor slides within the encapsulated shell, and the positioning of the probe sensor is achieved by adjusting the fastening bolts within the sliding groove, thus adjusting the spacing to 10mm. The ~15mm free adjustment helps optimize the acquisition range and accuracy of the detection signal, enabling the probe to acquire the magnetic memory signal of the detected area more comprehensively and accurately during the detection process, thus improving the reliability of the detection results. Furthermore, the use of an extension rod to drive the probe sensor up and down allows for independent adjustment of the probe sensor's lifting height. This design allows for flexible adjustment of the distance between the probe sensor and the workpiece surface according to different workpiece surface conditions, ensuring the sensor is always in the optimal detection position. This effectively enhances the probe sensor's adaptability to various complex workpiece surfaces, reducing the significant reduction in efficiency and accuracy in actual detection work and addressing the problem of failing to meet the ever-increasing detection demands.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 A sensor-adjustable four-wheel magnetic memory detection probe includes an aluminum alloy shell 1, with a detection probe body 2 snapped into the interior of the aluminum alloy shell 1. Two sets of extension rods 11 are fixedly connected to the output end of the detection probe body 2, and sprockets 12 are fixedly connected to the ends of the two sets of extension rods 11 that are far apart from each other. By fixing the two sets of extension rods 11 at the output end of the detection probe body 2, the sprockets 12 can be driven to rotate, thereby facilitating the movement of the four-wheel magnetic memory detection probe along the weld seam.

[0019] Each set of sprockets 12 has a chain 13 fitted on its outer surface. An encoder 14 is fixedly connected to the side of each set of sprockets 12 that is far apart from each other. The encoder 14 is a device that encodes and converts signals or data into a signal form that can be used for communication, transmission and storage. The encoder 14 is model HSD35. By using the chain 13 to connect the two sets of sprockets 12 in series, it can effectively avoid the situation where some sprockets 12 slip and cause displacement loss. This allows the encoder 14 to record the motion trajectory and displacement information of the probe more accurately during the detection process, providing more accurate data support for subsequent detection data analysis.

[0020] The bottom surface of the detection probe body 2 is provided with a detection arc groove 3. The right side of the detection probe body 2 is fixedly connected to a probe communication connector 15. The right end of the probe communication connector 15 passes through the aluminum alloy shell 1 and extends to the right side of the aluminum alloy shell 1. Through the probe communication connector 15, the four-wheel magnetic memory detection probe can be conveniently connected to external data, thereby facilitating real-time data transmission and storage.

[0021] A limiting baffle 4 is fixedly connected to the left side of the aluminum alloy shell 1 at equal intervals. Encapsulation shells 5 are arranged at equal intervals on the left side of the aluminum alloy shell 1. The sides of the two sets of limiting baffles 4 that are close to each other are in contact with the front and back sides of several encapsulation shells 5 respectively. A probe sensor 6 is slidably connected inside each encapsulation shell 5. A rotating rod 16 is fixedly connected to the inner wall of the detection probe body 2. The rotating rod 16 is rotatably connected to the inside of the aluminum alloy shell 1. Two locking rods 17 are fixedly connected to the outer surface of the rotating rod 16. The sides of the two locking rods 17 that are close to each other are in contact with the front and back sides of the aluminum alloy shell 1 respectively. The two locking rods 17 can be rotated by the rotating rod 16, thus facilitating the use of the locking structure.

[0022] Each encapsulation shell 5 has an electric telescopic rod 7 fixedly connected to its upper surface. The telescopic ends of several electric telescopic rods 7 are fixedly connected to the upper surfaces of several probe sensors 6. Each electric telescopic rod 7 has an extension telescopic rod 8 fixedly connected to its upper surface. The end of each extension telescopic rod 8 away from the electric telescopic rod 7 is fixedly connected to the upper surface of the aluminum alloy shell 1. The left ends of two locking diagonal rods 17 are fixedly connected to a pressing vertical plate 18. A fixing rubber pad 19 is provided on the right side of the pressing vertical plate 18. The left side of each encapsulation shell 5 is in contact with the right side of the fixing rubber pad 19. By rotating the two locking diagonal rods 17, the pressing vertical plate 18 pushes the fixing rubber pad 19 closer to the encapsulation shell 5, thereby facilitating the installation, pressing, and positioning of the encapsulation shell 5.

[0023] Each package housing 5 has an adjustment groove 9 on its left side. Each adjustment groove 9 has a fastening bolt 10 slidably connected inside. The right ends of several fastening bolts 10 are respectively in contact with the left side of several probe sensors 6. The right ends of two locking rods 17 are fixedly connected to a horizontal positioning plate 20. The internal threads of the horizontal positioning plate 20 are connected to a locking bolt 22. The bottom end of the locking bolt 22 passes through the horizontal positioning plate 20 and is connected to the internal threads of the aluminum alloy housing 1. By manually twisting the locking bolt 22, the locking bolt 22 can pass through the horizontal positioning plate 20 and be connected to the internal threads of the aluminum alloy housing 1, thereby further facilitating the installation, pressing and positioning of multiple package housings 5 ​​using this locking structure.

[0024] Both ends of the rotating rod 16 away from the aluminum alloy shell 1 are fixedly connected to baffles 21. The side of the two baffles 21 that is close to each other is in contact with the side of the two locking rods 17 that is far from each other. By using the baffles 21, the stability of the two locking rods 17 rotating outside the rotating rod 16 can be improved, thereby improving the locking stability of the locking structure.

[0025] The working principle of this utility model is as follows: In use, the four-wheel magnetic memory detection probe is first connected to a power source. When the adjustable four-wheel magnetic memory detection probe is needed to perform non-destructive testing on the weld, the probe is first manually placed on the upper surface of the weld. The aluminum alloy shell 1 is then manually placed over the outer surface of the probe body 2. The extension and retraction of the telescopic rod 8 allows the encapsulated shell 5, fixed at one end of the telescopic rod 8, and the electric telescopic rod 7 to slide along one side of the aluminum alloy shell 1. This allows multiple encapsulated shells 5 to move along multiple limiting baffles 4. Until multiple encapsulated housings 5 ​​can be moved to a suitable height, the rotating rod 16 is manually rotated so that the two locking rods 17, along with the pressing vertical plate 18 and the horizontal positioning plate 20, can rotate along the rotating rod 16 until the fixing rubber pad 19 fixed on one side of the pressing vertical plate 18 can contact and press against one side of the multiple encapsulated housings 5. Then, by manually twisting the locking bolt 22 inside the horizontal positioning plate 20, the locking bolt 22 can pass through the horizontal positioning plate 20 and be threaded into the inner wall of the aluminum alloy housing 1. Thus, the locking structure can be used to stably press and install multiple encapsulated housings 5. Next, by manually controlling the power supply of the electric telescopic rod 7, the electric telescopic rod 7 can drive the probe sensor 6 to slide along the encapsulation shell 5 until the probe sensor 6 has a suitable height, and the lifting height can be independently adjusted. Then, by manually moving the probe sensor 6 horizontally within the encapsulation shell 5, the distance between the two probe sensors 6 can be freely adjusted to 10~15mm. Furthermore, by manually twisting and adjusting the fastening bolts 10 in the slide groove 9, the probe sensor 6 within the encapsulation shell 5 is squeezed and positioned. After confirmation, the four-wheel magnetic memory detection probe can move along the weld seam. Using the extension rods 11 and sprockets 12 fixed at the output ends on both sides of the detection probe body 2, and using two chains 13 to synchronously roll the two sets of sprockets 12, the situation of displacement loss due to sprocket slippage can be effectively avoided. Furthermore, the encoder 14 records the motion trajectory and displacement information of the four-wheel magnetic memory detection probe, providing more accurate data support for subsequent detection data analysis.
