Description

Technical Field

[0001] This utility model relates to the field of weld inspection technology, and in particular to an ultrasonic testing device for inspecting welds in steel structures. Background Technology

[0002] In modern industrial construction, steel structures are widely used in various fields such as architecture, bridges, and machinery manufacturing due to their advantages of high strength and high stability. The quality of the welds in steel structures directly affects the safety and service life of the entire structure. Defects such as cracks, porosity, and lack of fusion in the welds can lead to serious safety accidents.

[0003] Existing ultrasonic testing devices for steel structure weld inspection typically consist of a probe, connecting cables, a main unit, and a support frame. The technical principle involves fixing and supporting the probe using the support frame. During testing, the operator holds the device or places it in a suitable position, ensuring the probe is in close contact with the surface of the steel structure weld. The main unit then controls the probe to emit ultrasonic waves. These waves propagate within the weld, generating reflected waves when they encounter defects. These reflected waves are received by the probe and transmitted to the main unit. The main unit processes and analyzes the signals, ultimately presenting the test results in waveform and other formats to help the inspector assess the weld quality.

[0004] However, in existing technologies, the connection structure between the probe and the device is relatively fixed, and the length of the probe cannot be flexibly adjusted according to actual testing needs. When inspecting steel structure welds at different locations and depths, if the probe length is insufficient, it is difficult to directly contact the weld area to be inspected. The inspector must then compensate for this deficiency indirectly by elevating themselves or adjusting the overall position of the device, which undoubtedly increases the operation time and safety risks. Therefore, an ultrasonic testing device for steel structure weld inspection is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an ultrasonic testing device for inspecting weld seams in steel structures, aiming to improve the problem in the prior art where inspectors need to indirectly compensate for insufficient probe length by raising the device or adjusting its overall position, which increases working time and safety risks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ultrasonic testing device for inspecting welds in steel structures includes a testing device, a connecting pipe fixedly connected to the side wall of the testing device, a fixing pipe fixedly connected to one end of the connecting pipe, and a snap-fit ​​assembly provided on the outer wall of the fixing pipe. The buckle assembly includes a fixing block, the bottom of which is fixedly connected to the outer wall of the fixing tube. A rotating column is fixedly connected inside the fixing block. A button is fixedly connected to one end of the rotating column. The side wall of the button is rotatably connected to the side wall of the fixing block. A limit post is fixedly connected to the bottom of the button. The outer wall of the limit post is slidably connected to the inside of the fixing tube. A spring-loaded component is provided at the bottom of the button.

[0007] As a further description of the above technical solution: The rebound assembly includes a first spring, one end of which is fixedly connected to the bottom of the button, and the other end of which is fixedly connected to the outer wall of the fixing tube.

[0008] As a further description of the above technical solution: The fixed tube has a slidably connected perforated column inside, and the outer wall of the limiting column is slidably connected inside the perforated column.

[0009] As a further description of the above technical solution: One end of the perforated column is fixedly connected to a fixed column, and the fixed column has a sliding groove inside.

[0010] As a further description of the above technical solution: A probe is slidably connected to the outer wall of the chute, and a rotating block is fixedly connected to the outer wall of the probe.

[0011] As a further description of the above technical solution: The side wall of the rotating block is slidably connected to the inside of the groove, and the outer wall of the rotating block is rotatably connected to the inside of the fixed column.

[0012] As a further description of the above technical solution: A hollow column is fixedly connected inside the fixed column, and a ball is slidably connected to the inner wall of the hollow column.

[0013] As a further description of the above technical solution: A second spring is provided on the inner wall of the hollow column. One end of the second spring is fixedly connected to the inside of the hollow column, and the other end of the second spring is fixedly connected to the outer wall of the ball. The outer wall of the ball is slidably connected to the side wall of the rotating block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, pressing the button causes the limiting column to rotate. At the same time, the button is forced to rotate the rotating column inside the fixed block. During the process of the button being forced, the first spring on the side wall is contracted, which causes the outer wall of the limiting column to disengage from the inside of the hole column. This achieves the effect of adjusting the probe length, solving the problem that the testing personnel need to indirectly compensate for the insufficient probe length by raising it or adjusting the overall position of the device, which increases the operation time and safety risks. This improves the practicality of the ultrasonic testing device for steel structure weld inspection.

[0015] 2. In this utility model, pressing the probe drives the rotating block on the outer wall to rotate inside the fixed column. Then, after aligning the side wall of the rotating block with the sliding groove, the probe can be pulled out. During this process, the rotating block is subjected to force, which squeezes the retaining ball on the side wall and causes the retaining ball to slide into the hollow column. At the same time, the retaining ball is subjected to force, which compresses the second spring, achieving the effect of quick probe disassembly. This solves the problem that if the probe cannot be quickly disassembled, it must be replaced through complicated steps, which will greatly increase downtime and reduce detection efficiency. This improves the convenience of the ultrasonic testing device for steel structure weld inspection. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5 An embodiment of this utility model is provided: an ultrasonic testing device for steel structure weld inspection, including a testing device 1, a connecting pipe 2 fixedly connected to the side wall of the testing device 1, a fixing pipe 3 fixedly connected to one end of the connecting pipe 2, and a buckle assembly provided on the outer wall of the fixing pipe 3; The snap-fit ​​assembly includes a fixing block 6, a rotating column 7, a button 8, and a limiting column 10. These components work in conjunction with a first spring 9 to perform telescopic locking movements, achieving rapid adjustment of the probe 5 length and automatic locking. This avoids the cumbersome operation of traditional heightening or moving devices. The bottom of the fixing block 6 is fixedly connected to the outer wall of the fixing tube 3. The rotating column 7 is fixedly connected inside the fixing block 6. One end of the rotating column 7 is fixedly connected to a button 8. The side wall of the button 8 is rotatably connected to the side wall of the fixing block 6. The bottom of the button 8 is fixedly connected to a limiting column 10, which is used to insert into the corresponding hole of the hole column 11, thereby achieving precise positioning of the fixing column 4. This significantly improves the controllability of the detection position and the repeatability of the positioning accuracy. The outer wall of the limiting column 10 is slidably connected inside the fixing tube 3. A spring-loaded assembly is provided at the bottom of the button 8. The spring-loaded assembly includes a first spring 9. One end of the first spring 9 is fixedly connected to the bottom of the button 8, and the other end is fixedly connected to the outer wall of the fixing tube 3.

[0020] Reference Figures 6-8A perforated column 11 is slidably connected inside the fixed tube 3. The outer wall of the limiting column 10 is slidably connected inside the perforated column 11. A fixed column 4 is fixedly connected to one end of the perforated column 11. A sliding groove 12 is opened inside the fixed column 4. A probe 5 is slidably connected to the outer wall of the sliding groove 12. A rotating block 13 is fixedly connected to the outer wall of the probe 5. The rotating block 13 slides linearly with the sliding groove 12, achieving the effect of quick disassembly and assembly of the probe 5, simplifying the replacement steps and reducing downtime. The side wall of the rotating block 13 is slidably connected inside the sliding groove 12, and the outer wall of the rotating block 13 is rotatably connected to the fixed column 4. Inside column 4, a hollow column 14 is fixedly connected. A ball 16 is slidably connected to the inner wall of the hollow column 14. A second spring 15 is provided on the inner wall of the hollow column 14. One end of the second spring 15 is fixedly connected to the inside of the hollow column 14, and the other end of the second spring 15 is fixedly connected to the outer wall of the ball 16. The ball 16 and the second spring 15 form an elastic locking structure. When the rotating block 13 reaches the preset position, it automatically locks, which enhances the stability of the probe 5 during operation and is especially suitable for complex detection scenarios. The outer wall of the ball 16 is slidably connected to the side wall of the rotating block 13.

[0021] Working principle: When the length of probe 5 needs to be adjusted, the inspector presses button 8. Button 8 drives the rotating column 7 to rotate inside the fixed block 6, while compressing the first spring 9. At this time, the limiting column 10 fixed at the bottom of button 8 disengages from the hole column 11, releasing the lock on the hole column 11. The inspector can freely slide the fixed column 4 and probe 5 to the required length. After releasing button 8, the first spring 9 rebounds and pushes the limiting column 10 back into the corresponding hole of the hole column 11, completing the locking. This achieves rapid adjustment of the length of probe 5, avoiding the cumbersome operation of raising or moving the device in the traditional method, and significantly improving inspection efficiency and safety. When replacing probe 5, the inspector presses probe 5 to align its rotating block 13 with the slide groove 12. At the same time, the rotating block 13 squeezes the retaining ball 16, which retracts into the hollow column 14 and compresses the second spring 15. Probe 5 can then be easily pulled out or inserted along the slide groove 12. After probe 5 reaches the preset position, the second spring 15 pushes the retaining ball 16 to reset and lock it into the groove of the rotating block 13, achieving a stable fixation. This simplifies the probe 5 replacement process, reduces downtime, and is especially suitable for complex testing scenarios where probe 5 needs to be replaced frequently, further enhancing the practicality and convenience of the device.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
