Description

Technical Field

[0001] This application relates to the field of pipeline weld inspection technology, specifically a portable ultrasonic scanner for inspecting pipeline welds. Background Technology

[0002] Pipelines are widely used in industrial production, from transporting oil and natural gas to transmitting various chemical fluids; they are ubiquitous. Pipeline welds, as critical connections, directly affect the safe operation of the pipeline system. Defects in the welds, under long-term pressure and corrosion, can lead to serious accidents such as leaks and explosions, causing not only huge economic losses but also threatening human lives.

[0003] Ultrasonic testing is a commonly used non-destructive testing method. It utilizes the propagation characteristics of ultrasonic waves in different media. When ultrasonic waves encounter defects inside a weld, they will undergo reflection, refraction, and other phenomena. By analyzing these signals, the location, size, and nature of the defects can be determined.

[0004] Current ultrasonic scanners typically consist of a scanner body and an ultrasonic probe, which is electrically connected to the scanner body via a wire. During transport, people often simply wrap the probe's wire around the scanner, a method with significant drawbacks. Due to the lack of effective fixation, the ultrasonic probe is prone to swinging during transport. This swinging causes constant tension on the wire connection, which over time can loosen, leading to poor connection. This not only affects the normal use of the ultrasonic probe but may also result in inaccurate detection data, delaying the detection and treatment of pipe weld defects.

[0005] Therefore, this application provides a portable ultrasonic scanner for inspecting pipe welds to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a portable ultrasonic inspection scanner for pipe welds, aiming to solve the problems mentioned in the background art, such as the ultrasonic probe being easily shaken during carrying, leading to poor connection.

[0007] To achieve the above objectives, this application provides the following technical solution: a portable ultrasonic inspection scanner for pipe welds, comprising a scanner body and an ultrasonic probe, wherein the ultrasonic probe is connected to the scanner body via a wire.

[0008] For ease of portability, the scanner body is equipped with a fixing mechanism for securing the ultrasonic probe. This mechanism includes a mounting plate on the scanner body, a mounting base fixed to the mounting plate for securing the ultrasonic probe, and a retainer fixed to the mounting base for securing the ultrasonic probe's connector. The ultrasonic probe's wires are wound around the mounting base. When carrying the device, first neatly wind the ultrasonic probe's wires around the mounting base to prevent damage from tangled wires. Then, precisely secure the connector at the end of the ultrasonic probe to the retainer, thus securing the ultrasonic probe to the scanner body. This allows for easy carrying of both components as a single unit. This effectively prevents the ultrasonic probe from swinging during transport due to the lack of a fixing structure, thus preventing poor cable connections and ensuring the testing equipment is always ready for normal use, improving the efficiency and reliability of the testing process.

[0009] Preferably, to ensure the scanner body is stably positioned on the welded pipe during inspection, two sets of magnetic rods are symmetrically fixed to the lower end of the scanner body. Each set of magnetic rods consists of two rods, forming a slot between the two sets. During inspection, the inspector brings the scanner body close to the welded pipe, aligning the slot with the pipe. Because the shape of the slot matches the curvature of the welded pipe surface, the scanner body naturally engages with it. At this point, the two sets of magnetic rods are firmly adhered to the surface of the welded pipe. The matching design of the slot with the curvature of the welded pipe surface achieves initial positioning and installation of the scanner body. The adsorption effect between the two sets of magnetic rods and the welded pipe further enhances the stability of the scanner body, preventing it from easily shaking or slipping during inspection. This ensures that the ultrasonic probe maintains continuous and stable contact with the weld seam of the welded pipe, guaranteeing the accuracy and reliability of the inspection data and reducing inspection errors caused by equipment movement.

[0010] Preferably, to facilitate vertical adjustment of the ultrasonic probe during use, the scanner body is movably equipped with a lifting mechanism for driving the ultrasonic probe's vertical movement. The lifting mechanism includes a guide rail, a slider slidably mounted on the guide rail and fixedly connected to the mounting plate, and a bolt threaded onto the slider and abutting against the guide rail. Before starting the inspection, the inspector removes the guide rail from the scanner body and places it in a suitable position on the welded pipe. Then, the position of the slider on the guide rail is adjusted by rotating the bolt. Rotating the bolt clockwise gradually tightens the bolt, increasing the pressure on the guide rail and enhancing the slider's fixation. Rotating the bolt counterclockwise gradually loosens the bolt, allowing the slider to slide freely on the guide rail. The inspector slowly adjusts the slider's position according to the actual condition of the welded pipe and the inspection requirements until the ultrasonic probe makes good contact with the surface of the welded pipe, then tightens the bolt again to fix the slider's position. Inspectors can flexibly adjust the height of the ultrasonic probe according to the different diameters of the welded pipes, the unevenness of the welded pipe surface, and the specific requirements of the inspection, to ensure that the ultrasonic probe can fit tightly against the surface of the welded pipe and improve the accuracy of the inspection.

[0011] Preferably, to facilitate the installation of the guide rail on the scanner body, a socket compatible with the guide rail is fixedly connected to the bottom of the scanner body, and the guide rail is inserted into the socket. When carrying the device, the guide rail is inserted into the socket and then removed for easy transport; when in use, the guide rail is simply and quickly removed from the socket.

[0012] Preferably, to facilitate stable placement of the guide rail on the welded pipe during weld seam inspection, a magnetic block is fixedly embedded at the lower end of the guide rail. When the guide rail is placed on the welded pipe, the magnetic block at the lower end of the guide rail immediately attracts to the surface of the welded pipe. Even if slight vibrations or external forces are encountered during the inspection process, the magnetic block ensures that the guide rail will not easily shift. The attraction between the magnetic block and the welded pipe ensures that the guide rail is stably placed on the welded pipe during the inspection process. This provides a stable basis for the precise adjustment of the distance between the ultrasonic probe and the welded pipe, ensures the stability of the ultrasonic probe position during the inspection process, and further improves the accuracy and reliability of the inspection data.

[0013] This application utilizes a fixing mechanism to securely mount the ultrasonic probe onto the scanner body, facilitating its transport as a single unit. This effectively prevents the ultrasonic probe from swinging during transport due to the lack of a fixing structure, thus preventing cable connection problems and ensuring the testing equipment is always ready for normal use, thereby improving the efficiency and reliability of the testing process.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] This embodiment provides a portable ultrasonic scanner for inspecting pipe welds, such as... Figure 1-4 As shown, the scanner includes a scanner body 1 and an ultrasonic probe 2, which is connected to the scanner body 1 via a wire.

[0022] For ease of portability, the scanner body 1 is equipped with a fixing mechanism 3 for fixing the ultrasonic probe 2. The fixing mechanism 3 includes a mounting plate 31 on the scanner body 1, a mounting base 32 fixedly mounted on the mounting plate 31 for fixing the ultrasonic probe 2, and a retaining holder 33 fixedly mounted on the mounting base 32 for fixing the connector of the ultrasonic probe 2. The wires of the ultrasonic probe 2 are wound around the mounting base 32. The fixing mechanism 3 allows the ultrasonic probe 2 to be mounted on the scanner body 1, facilitating easy carrying of the ultrasonic probe 2 and the scanner body 1 as a single unit. This prevents the ultrasonic probe 2 from swinging during transport due to the lack of a fixing structure on the scanner body 1, which could cause poor cable connection. During assembly, the ultrasonic probe 2 is fixedly mounted on the mounting base 32. For carrying, the wires of the ultrasonic probe 2 are wound around the mounting base 32, and then the connector at the end of the ultrasonic probe 2 is secured to the retaining holder 33 to complete the fixation of the ultrasonic probe 2 to the scanner body 1. In use, remove the connector from the holder 33, then remove the wire from the mounting base 32. Next, connect the connector to the connector on the scanner body 1. Then, place the mounting plate 31 on the welded pipe, ensuring the ultrasonic probe 2 is in contact with the pipe. Ultrasonic testing of the weld seam can then be performed. During this process, the inspector can clearly see the connection status between the ultrasonic probe 2 and the scanner body 1, facilitating operation. Furthermore, the design of the fixing mechanism 3 makes the equipment more compact and less prone to damage during transport.

[0023] To ensure the scanner body 1 is stably positioned on the welded pipe during inspection, two sets of magnetic rods 11 are symmetrically fixed to the lower end of the scanner body 1. Each set of magnetic rods 11 consists of two rods, forming a slot 12 between the two sets. During inspection, the slot 12 adapts to the curvature of the welded pipe surface, allowing for the positioning and installation of the scanner body 1. Combined with the two sets of magnetic rods 11, this ensures the scanner body 1 is stably positioned on the welded pipe. When the inspector places the scanner body 1 on the welded pipe, the slot 12 quickly aligns with the pipe, providing initial positioning. Subsequently, the magnetic rods 11 adhere tightly to the surface of the welded pipe, ensuring the scanner body 1 remains stable even when the inspector moves the equipment, preventing any shifting and guaranteeing the continuity and accuracy of the inspection.

[0024] To facilitate the vertical adjustment of the ultrasonic probe 2 during use, a lifting mechanism 4 is movably mounted on the scanner body 1 to drive the ultrasonic probe 2 to move up and down. The lifting mechanism 4 includes a guide rail 41, a slider 42 slidably sleeved on the guide rail 41 and fixedly connected to the mounting plate 31, and a bolt 43 threadedly inserted into the slider 42 and abutting against the guide rail 41. During inspection, the guide rail 41 is removed from the scanner body 1 and placed on the welded pipe. The position of the slider 42 on the guide rail 41 is then adjusted using the tightening bolt 43, bringing the ultrasonic probe 2 into contact with the surface of the welded pipe. The structure is simple and easy to adjust. Inspectors can quickly adjust the height of the ultrasonic probe 2 according to the actual condition of the welded pipe.

[0025] To facilitate the installation of the guide rail 41 on the scanner body 1, a socket 5 adapted to the guide rail 41 is fixedly connected to the bottom of the scanner body 1, and the guide rail 41 is inserted into the socket 5. When carrying the device, the guide rail 41 is inserted into the socket 5 and then pulled out for easy carrying; when using the device, the guide rail 41 is removed from the socket 5, which is simple and quick.

[0026] To facilitate the stable placement of the guide rail 41 on the welded pipe during weld seam inspection, a magnetic block 411 is fixedly embedded at the lower end of the guide rail 41. The attraction between the magnetic block 411 and the welded pipe ensures the guide rail 41 is stably positioned on the pipe, thus facilitating the adjustment of the distance between the ultrasonic probe 2 and the welded pipe. During the inspection process, the magnetic block 411 effectively prevents the guide rail 41 from sliding, providing a stable platform for the precise adjustment of the ultrasonic probe 2.

[0027] It should be noted that many of the standard parts used in this invention are available on the market, while non-standard parts can be specially customized. The connection method used in this invention is also a very common method in the mechanical field, which the inventor will not elaborate on here.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
