Description

Technical Field

[0001] This utility model relates to the technical field of weld inspection equipment, specifically a non-destructive testing device for pressure pipeline welds. Background Technology

[0002] In industrial production, pressure pipelines are key equipment for transporting fluid media, and the quality of their welds directly affects the operational safety of the system. If defects such as cracks, porosity, or slag inclusions exist in the welds, they may cause serious accidents such as leaks and explosions. Therefore, accurate and efficient non-destructive testing of pressure pipeline welds is crucial. Currently, ultrasonic testing is widely used in pressure pipeline weld testing due to its advantages such as high sensitivity, strong penetration, and no damage to the human body. The stability and ease of operation of its core component, the ultrasonic probe, directly affect the accuracy of the test results.

[0003] Currently, most pressure pipeline weld non-destructive testing equipment lacks a dedicated storage structure for ultrasonic probes. When the probes are not in use, they are often simply placed next to the testing equipment or in a separate storage box. The detection end of the ultrasonic probe is quite delicate, and direct exposure to the outside can easily cause wear or damage due to bumps and pressure. Especially in complex on-site operating environments, dust, oil and other impurities can adhere to the probe surface, affecting the subsequent coupling effect with the weld and causing the detection signal to be distorted. Utility Model Content

[0004] The purpose of this invention is to provide a non-destructive testing device for pressure pipeline welds, which solves the problem that most non-destructive testing devices for pressure pipeline welds lack a dedicated storage structure for ultrasonic probes. When the probe is not in use, it can only be placed randomly next to the testing equipment or in a separate storage box. The detection end of the ultrasonic probe is relatively delicate, and direct exposure to the outside makes it susceptible to wear or damage due to bumps and squeezing. Especially in complex on-site working environments, dust, oil and other impurities can adhere to the probe surface, affecting the subsequent coupling effect with the weld and causing the detection signal to be distorted.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-destructive testing device for pressure pipeline welds, comprising an ultrasonic probe, a weld non-destructive testing device sleeved on the surface of the connecting end of the ultrasonic probe, a fixed clamping seat provided on the top of the ultrasonic probe, a movable clamping seat provided on the bottom of the ultrasonic probe, a support frame movably connected to the front side of the weld non-destructive testing device, and an opening and closing mechanism movably connected to the surface of the movable clamping seat.

[0006] Preferably, the opening and closing mechanism includes a slide rod, which is slidably connected to both sides of the movable clamp. Mounting plates are fixedly connected to the top and bottom of the slide rod. The rear side of the mounting plates is fixedly connected to the front side of the weld non-destructive testing equipment. A spring is sleeved on the bottom surface of the slide rod. The bottom of the spring is fixedly connected to the surface of the mounting plates, and the top of the spring is fixedly connected to the bottom of the movable clamp. A rotating component is movably connected inside the movable clamp, and the rear side of the rotating component is movably connected to the front side of the weld non-destructive testing equipment.

[0007] Preferably, a limiting block is provided on the right side of the bottom of the rotating component, and the rear side of the limiting block is fixedly connected to the front side of the weld non-destructive testing equipment.

[0008] Preferably, a handle is fixedly connected to the front side of the rotating component, and the handle is located on the front side of the weld non-destructive testing equipment.

[0009] Preferably, a triangular rib is fixedly connected to the bottom of the movable clamp, and the triangular rib is located on the front side of the weld non-destructive testing equipment.

[0010] Preferably, a storage sleeve is fixedly connected to the bottom of the front side of the weld non-destructive testing equipment, and the storage sleeve is located inside the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adds a support frame and other structures to the non-destructive testing equipment for welds. The support frame enhances the overall support stability of the device, enabling more accurate detection of pressure pipeline welds, improving detection efficiency and reliability. The structure is also compact, making it easy to operate and move.

[0012] 2. This utility model achieves a stable connection between the ultrasonic probe and the testing equipment by adding a fixed clamp and a movable clamp to the weld non-destructive testing equipment. When the ultrasonic probe is restricted, it will shake freely. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-4 A pressure pipeline weld non-destructive testing device includes an ultrasonic probe 1, a weld non-destructive testing device 2 is sleeved on the surface of the connecting end of the ultrasonic probe 1, a fixed clamp 3 is provided on the top of the ultrasonic probe 1, a movable clamp 4 is provided on the bottom of the ultrasonic probe 1, a support frame 5 is movably connected to the front side of the weld non-destructive testing device 2, and an opening and closing mechanism is movably connected to the surface of the movable clamp 4.

[0017] Please see Figure 1-3 The opening and closing mechanism includes a slide rod 61, which is slidably connected to both sides of the movable clamp 4. Mounting plates 62 are fixedly connected to the top and bottom of the slide rod 61. The rear side of the mounting plates 62 is fixedly connected to the front side of the weld non-destructive testing equipment 2. A spring 63 is sleeved on the bottom of the surface of the slide rod 61. The bottom of the spring 63 is fixedly connected to the surface of the mounting plates 62. The top of the spring 63 is fixedly connected to the bottom of the movable clamp 4. A rotating part 64 is movably connected inside the movable clamp 4. The rear side of the rotating part 64 is movably connected to the front side of the weld non-destructive testing equipment 2.

[0018] Furthermore, the sliding rod 61 and the movable clamp 4 enable automatic reset of the movable clamp 4, while the rotating part 64 allows for flexible control of the opening and closing angle of the movable clamp 4, making the installation and removal of the ultrasonic probe 1 more convenient. At the same time, the fixing structure of the sliding rod 61 and the mounting plate 62 ensures the stability of the movement of the movable clamp 4, preventing the detection accuracy from being affected by loosening during the detection process. The overall structure is simple and highly practical, effectively improving the ease of operation of the device.

[0019] Please see Figure 1-3 A limit block 7 is provided on the right side of the bottom of the rotating part 64, and the rear side of the limit block 7 is fixedly connected to the front side of the weld non-destructive testing equipment 2.

[0020] Furthermore, by setting the limit block 7, the excessive rotation of the rotating part 64 can be prevented from causing the opening and closing angle of the movable clamp 4 to be too large, thus avoiding the ultrasonic probe 1 from being dislodged from the detection position or being damaged due to excessive displacement. This ensures the safety and stability of the opening and closing mechanism and further improves the service life and detection reliability of the device.

[0021] Please see Figure 1-3 A handle 8 is fixedly connected to the front side of the rotating part 64, and the handle 8 is located on the front side of the weld non-destructive testing equipment 2.

[0022] Furthermore, by setting the handle 8, the rotation operation of the rotating part 64 can be made more labor-saving and flexible, and it is convenient to quickly adjust the opening and closing state of the movable clamp 4, shortening the installation and debugging time of the ultrasonic probe 1 and improving the preparation efficiency before detection, especially in confined spaces or frequent operation scenarios.

[0023] Please see Figure 1-3 The bottom of the movable clamp 4 is fixedly connected with a triangular rib 9, which is located on the front side of the weld non-destructive testing equipment 2.

[0024] Furthermore, the triangular rib 9 prevents deformation during long-term use or under stress, ensuring the stability of the movable clamp 4 in holding the ultrasonic probe 1, reducing detection errors caused by structural deformation, extending the service life of the device, and improving the overall reliability of the structure.

[0025] Please see Figure 1-2 The bottom front of the weld non-destructive testing equipment 2 is fixedly connected to a storage sleeve 10, which is located inside the support frame 5.

[0026] Furthermore, the storage sleeve 10 can store the support frame 5 when the device is idle or moved, preventing damage to the support frame 5 due to shaking or collision. At the same time, it makes the overall structure of the device more compact, saves storage space, and makes it easier to carry and transport, thus improving the practicality and portability of the device.

[0027] The specific implementation process of this utility model is as follows: When in use, the ultrasonic probe 1 is fixed on the surface of the weld non-destructive testing equipment 2. When the ultrasonic probe 1 is not in use, the detection end of the ultrasonic probe 1 is fixed inside the fixed clamp 3 and the movable clamp 4, and then the connection end of the ultrasonic probe 1 is inserted into the inside of the storage sleeve 10. When the ultrasonic probe 1 and the weld non-destructive testing equipment 2 are needed, pull the connecting end of the ultrasonic probe 1 out from the inside of the storage sleeve 10, and then insert it into the top of the weld non-destructive testing equipment 2. Twist the rotating part 64 to rotate, and the rotating part 64 will drive the movable clamp 4 to move downward. The movable clamp 4 compresses the spring 63, and the distance between the movable clamp 4 and the fixed clamp 3 increases. The ultrasonic probe 1 loses the clamping and fixing of the fixed clamp 3 and the movable clamp 4, and the ultrasonic probe 1 can be removed for work.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
