Description
TECHNICAL FIELD
[0001] The application relates to the technical field of pipeline detection equipment, and particularly relates to ultrasonic detection equipment for pipeline welds. BACKGROUND
[0002] In the installation and maintenance of industrial pipelines, the detection of weld quality is an important link to ensure the safe operation of the pipeline system, and traditional pipeline weld detection methods mostly rely on ultrasonic detection technology, which judges whether cracks, pores, slag inclusions and other defects exist in the pipeline weld by emitting ultrasonic signals and receiving reflected waves.
[0003] However, in actual application, especially on some high or hard-to-reach pipelines, current ultrasonic detection equipment is mostly designed as handheld or fixed type, and when the existing ultrasonic detection equipment is used for weld inspection, the operation of the equipment needs the direct contact and operation of the staff and the probe, many pipelines are installed at high positions or hard-to-reach positions, and the staff needs to use ladders or hoisting equipment to perform weld detection, which not only increases the operation difficulty, but also causes the unsafe working environment and increases the risk exposure of the staff
[0004] Therefore, the application provides ultrasonic detection equipment for pipeline welds to solve the above problems. CONTENT OF THE INVENTION
[0005] The application provides ultrasonic detection equipment for pipeline welds, and aims to solve the problem that many pipelines are installed at high positions or hard-to-reach positions, and the staff needs to use ladders or hoisting equipment to perform weld detection, which increases the operation difficulty.
[0006] To achieve the above purpose, the application provides the following technical scheme: ultrasonic detection equipment for pipeline welds, comprising an ultrasonic detector main body and a column handle, a flexible line is installed on the column handle, a probe is installed at one end of the flexible line away from the column handle, a wireless communication module is arranged in the probe, and the probe is connected with the ultrasonic detector main body through the wireless communication module.
[0007] An auxiliary mechanism is arranged on the flexible line, and a handheld rod is arranged at the tail end of the column handle.
[0008] The auxiliary mechanism includes a fixed ring set on the flexible line, a fixed block fixedly installed on the fixed ring, a support block set on the fixed block, a positioning frame fixedly installed on the upper end of the support block, and an electronic infrared sensor detachably installed on the positioning frame. The ultrasonic detector body and the probe in this ultrasonic testing equipment are mainly connected wirelessly, relying on the wireless communication module inside the probe and the wireless receiving unit inside the ultrasonic detector body to reduce the influence of the line and make it easier for staff to perform pipeline testing operations.
[0009] Preferably, a collar is fitted onto the flexible circuit, one end of which is conical. By fitting the collar onto the flexible circuit, the position of the electronic infrared radiation can be freely adjusted.
[0010] Preferably, the collar has several strip grooves, and the fixing ring is threadedly connected to the collar. After the fixing ring is threadedly connected to the collar, the collar ensures that the electronic infrared light remains in position when it is compressed by the strip grooves.
[0011] Preferably, the handheld rod has a telescopic end that is movably inserted into it. The end of the telescopic end away from the handheld rod has a threaded groove. A sleeve is fitted into the threaded groove. The handle is inserted into the inside of the sleeve. The sleeve is threaded into the threaded groove at the front end of the telescopic end, thereby ensuring that the probe is fixed on the telescopic end by the handle and the sleeve. Finally, the operator can hold the handheld rod to inspect the pipeline at a high position.
[0012] Preferably, the inner wall of the handheld lever has a concave circular groove at one end near the telescopic end. Springs are symmetrically distributed inside the telescopic end, and each spring is equipped with a ball bearing for movably engaging with the telescopic end. The ball bearing is adapted to the concave circular groove. When the telescopic end is stretched, the ball bearing is pushed into the concave circular groove by the spring, achieving position locking. The combination of the ball bearing and the spring provides a reliable locking force, preventing the lever from accidentally sliding during high-altitude operations and improving safety.
[0013] This ultrasonic testing equipment allows operators to hold the probe close to the surface of the pipe weld using a handheld lever. Electronic infrared beams project a spot to mark the testing area, and a flexible circuit transmits ultrasonic signals to the main body of the ultrasonic testing instrument for real-time analysis. Meanwhile, a fixing ring and a fixing block ensure the stability of the circuit, a wireless communication module prevents cable tangling, and electronic infrared assists in precise positioning, reducing the false detection rate.

[0023] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This embodiment provides an ultrasonic testing device for pipe welds, such as... Figures 1-7 As shown, the ultrasonic testing device includes an ultrasonic testing instrument body 1 and a handle 2. A flexible line 21 is installed on the handle 2. A probe 22 is installed at the end of the flexible line 21 away from the handle 2. A wireless communication module is installed inside the probe 22. The probe 22 is connected to the ultrasonic testing instrument body 1 through the wireless communication module.
[0025] An auxiliary mechanism 3 is provided on the flexible line 21, and a hand handle 4 is provided at the tail end of the column handle 2;
[0026] The auxiliary mechanism 3 includes a fixing ring 31 set on the flexible line 21, a fixing block 34 fixedly installed on the fixing ring 31, a support block 35 set on the fixing block 34, a positioning frame 36 fixedly installed on the upper end of the support block 35, and an electronic infrared ray 32 detachably installed on the positioning frame 36.
[0027] Specifically, by using the fixing ring 31 in conjunction with the collar 33 fitted on the flexible circuit 21, the electronic infrared ray 32 is installed on the flexible circuit 21, and the electronic infrared ray 32 is kept parallel to the probe 22. Therefore, when the staff raises the probe 22, they can intuitively determine the position pointed to by the red dot emitted by the infrared ray, thereby improving the accuracy of the detection.
[0028] A collar 33 is fitted on the flexible line 21. One end of the collar 33 is conical and has several slots. A fixing ring 31 is threadedly fitted onto the collar 33. After the fixing ring 31 is threadedly fitted onto the collar 33, the collar 33 is fitted onto the collar 33.
[0029] More specifically, the collar 33 can freely adjust the position of the electronic infrared ray 32 by being fitted onto the flexible circuit 21. The conical area at the front end of the collar 33 is made of plastic, which will firmly grip the flexible circuit 21 and remain fixed when squeezed. The collar 33 ensures that the electronic infrared ray 32 remains in position when squeezed by the groove.
[0030] A telescopic end 42 is movably inserted into the hand handle 4. A threaded groove is provided at the end of the telescopic end 42 away from the hand handle 4. A sleeve 41 is fitted into the threaded groove, and the column handle 2 is inserted into the sleeve 41.
[0031] It should be noted that when encountering pipelines at high altitudes that need to be inspected, manually align the column handle 2 with the sleeve 41 and insert it. Then, thread the sleeve 41 into the threaded groove at the front end of the telescopic end 42 to ensure that the probe 22 is fixed on the telescopic end 42 through the column handle 2 and the sleeve 41. Finally, the staff can hold the hand rod 4 to inspect the pipelines at high altitudes.
[0032] The inner wall of the handheld lever 4 has a concave circular groove at one end near the telescopic end 42. Springs 44 are symmetrically distributed inside the telescopic end 42. Each spring 44 is equipped with a ball bearing 43 for movably engaging with the telescopic end 42. The ball bearing 43 is adapted to the concave circular groove.
[0033] It is worth mentioning that when the telescopic end 42 is stretched, the ball 43 is pushed into the concave groove by the spring 44, achieving positioning and locking. Since the concave groove is less than one-third the size of the ball 43, when it is retracted later, it is only necessary to press the telescopic end 42 against the hand handle 4 to compress the ball 43 and squeeze it into the interior of the telescopic end 42. The combination of the ball 43 and the spring 44 provides a reliable locking force, preventing the pole from accidentally sliding during high-altitude operations and improving safety.
[0034] In use, the ultrasonic testing device's main body 1 and probe 22 are primarily connected wirelessly. This relies on the wireless communication module inside the probe 22 and the wireless receiving unit inside the main body 1 to reduce the impact of wiring, making it easier for operators to inspect pipelines. By using a fixing ring 31 and a collar 33 fitted onto the flexible line 21, the electronic infrared ray 32 is mounted on the flexible line 21, and the electronic infrared ray 32 is kept parallel to the probe 22. Therefore, when the operator raises the probe 22, they can directly determine the position pointed to by the red dot emitted by the infrared ray, thereby improving the accuracy of the inspection.
[0035] 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.
