Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic flaw detection, and in particular relates to an ultrasonic detection device for boiler pipelines. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting part defects by using the characteristic that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe into the metal interior, reflected waves are generated when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The location and size of the defects are determined based on these pulse waveforms.

[0003] However, the ultrasonic detection devices for boiler pipes currently on the market cannot meet the use requirements. When detecting boiler pipes installed at a high position, the user cannot hold the flaw detection metal block to detect the boiler pipe, and the flaw detection metal block is easy to collide with the metal hard objects next to the high boiler pipe when the flaw detection metal block approaches the high boiler pipe. Based on the above problems, a boiler pipe ultrasonic detection device is proposed. Summary of the invention

[0004] The object of the present invention is to provide a boiler pipe ultrasonic detection device to solve the problem proposed in the above background technology that when detecting high-position boiler pipes, the flaw detection metal block cannot directly reach the position of the boiler pipe, making it inconvenient to detect and unable to protect the flaw detection metal block.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a boiler pipeline ultrasonic detection device, comprising an ultrasonic detector body, a data cable is installed on the top of the ultrasonic detector body, and a plug is installed at one end of the data cable, a connecting block is installed on one side of the plug, a connecting rod is installed at the bottom of the connecting block, and a universal ball is installed on one side of the connecting block, a universal ball seat is installed on one side of the universal ball, and a flaw detection metal block is installed on one side of the universal ball seat.

[0006] Preferably, the outer wall of the universal ball seat is fixedly connected to a fixing ring by bolts, and the outer wall of the fixing ring is provided with ten damping springs distributed in a ring shape, a protective rubber rod is installed on one side of the damping spring, and a rubber protective ball is installed on one end of the protective rubber rod.

[0007] Preferably, the bottom end of the connecting rod is screwed with the telescopic rod through a thread, and a rust-proof coating is provided on one side of the telescopic rod.

[0008] Preferably, a plug plate is provided on one side of the ultrasonic detector body, and the plug plate is an L-shaped structure.

[0009] Preferably, a mounting plate is installed on the ultrasonic detector body at a position on one side close to the telescopic rod, and a mounting groove is provided inside the mounting plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) The present invention is provided with a connecting rod, a universal ball seat, a universal ball and a telescopic rod. The flaw detection metal block is installed on the universal mechanism, and then the telescopic rod is held to detect the boiler pipeline at a high position. This solves the problem that when detecting the boiler pipeline installed at a high position, the user cannot hold the flaw detection metal block to detect the boiler pipeline. It is convenient for the user to detect the boiler pipeline at a high position, and avoids the problem of the danger caused by the user using a climbing tool to detect the boiler pipeline at a high position. At the same time, the efficiency of detecting the boiler pipeline is improved and the operation difficulty of the staff is reduced.

[0012] (2) The present invention is provided with a fixing ring, a protective rubber rod and a damping spring, and the fixing ring is fixed on the outer wall of the universal ball seat. The protective rubber rod is installed on the fixing ring to form an elastic protective cover with the protective rubber rod to protect the surrounding of the flaw detection metal block. The problem that the flaw detection metal block is easy to collide with the metal hard objects beside the high boiler pipe when the flaw detection metal block is close to the high boiler pipe is solved, the safety of the flaw detection metal block is improved, and the problem that the flaw detection metal block collides with the hard objects during the detection process, causing the ultrasonic detection device to be abnormal, is avoided.

[0021] In order to protect the flaw detection metal block 4, preferably, the outer wall of the universal ball seat 3 is fixedly connected to the fixing ring 12 by bolts, and the outer wall of the fixing ring 12 is provided with ten damping springs 10 distributed in a ring shape, a protective rubber rod 5 is installed on one side of the damping spring 10, and a rubber protective ball 11 is installed on one end of the protective rubber rod 5, and an elastic protective cover is formed by the protective rubber rod 5 to protect the flaw detection metal block 4 all around, thereby improving the safety of the flaw detection metal block 4 and avoiding the problem that the flaw detection metal block 4 collides with hard objects during the detection process, thereby causing abnormalities in the ultrasonic detection device.

[0022] For the convenience of use by users, preferably, the bottom end of the connecting rod 8 is screwed with the telescopic rod 9 through a thread, and one side of the telescopic rod 9 is provided with an anti-rust coating.

[0023] In order to facilitate the user to view the graphics on the ultrasonic detector body 2, preferably, a plug plate 15 is provided on one side of the ultrasonic detector body 2, and the plug plate 15 is an L-shaped structure.

[0024] In order to facilitate the installation of the ultrasonic detector body 2 , preferably, a mounting plate 1 is installed on one side of the ultrasonic detector body 2 close to the telescopic rod 9 , and a mounting groove 14 is provided inside the mounting plate 1 .

[0025] The working principle and use process of the present invention are as follows: the user fully charges the ultrasonic detector. When inspecting a boiler pipe installed at a low position, the user inserts the plug 13 into the connecting block 7. The interior of the connecting block 7 is connected to the access end of the flaw detection metal block 4. At this time, the data cable 6 connects the flaw detection metal block 4 and the ultrasonic detector body 2. The user holds the connecting rod 8 and sticks the flaw detection metal block 4 to the outer surface of the boiler pipe. The ultrasonic energy emitted by the ultrasonic detector body 2 penetrates deep into the boiler pipe, and when entering another section from one section, reflection occurs at the edge of the interface to inspect part defects. When inspecting a boiler pipe installed at a high position, the user takes out the telescopic rod 9, and then connects the connecting rod 8 to the telescopic rod 9 by screwing the connecting rod 8. The ultrasonic detector body 2 is fixed on the telescopic rod 9, and the user lifts the telescopic rod 9 to bring the flaw detection metal block 4 close to the boiler pipe at a high place. In the process of approaching, the protective rubber stick 5 is hit by other pipes and hard objects. At this time, the damping spring 10 will be deformed, and the vibration will be reduced through the damping characteristics. At the same time, the flaw detection metal block 4 is protected and the flaw detection metal block 4 is attached to the surface of the boiler pipe for detection. At the same time, the user moves the telescopic rod 9 to change the position of the flaw detection metal block 4. When the flaw detection metal block 4 moves, the universal ball 16 rotates inside the universal ball seat 3, and the direction is reversed so that the flaw detection metal block 4 is attached to the outer wall of the boiler pipe. After the detection is completed, the ultrasonic detection device is stored.
