Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas pipeline detection, in particular to a mobile pipeline defect detection device adapted to functions of different pipe diameters. 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] For example, the utility model patent with the authorization announcement number CN219775492U and the authorization announcement date 2023.09.29 discloses a mobile pipeline defect detection device with the function of adapting to different pipe diameters. The patent design uses a pipe diameter matching component to adapt to pipes of different diameters, and uses a driving component to drive the detection component to move, so as to realize all-round defect detection of the pipeline, with more precise detection and accurate location of the defect.
[0004] Although the above patent can adapt to gas pipes of different diameters, the above patent still has the following defects: the device is sleeved on the outside of the gas pipeline and then moves along the gas pipeline. However, a support column is fixed at the bottom of the gas pipeline when the gas pipeline is laid, and the gas pipeline is supported by the support column. The device cannot pass through the support column smoothly. Under the action of the support column, the device cannot continuously detect the gas pipeline. If a detection device is installed on the lower side of each section of the gas pipeline, the overall use cost will increase. Therefore, in view of the above problems, a mobile pipeline defect detection device that is adapted to different pipe diameters is proposed. Utility Model Content

In addition, multiple ultrasonic probes 10 on the shell 1 and the half-toothed ring 9 can be set according to the detection requirements, so that the shell 1 and the ultrasonic probes 10 on the half-toothed ring 9 can detect the four sides of the gas pipeline at the same time, thereby ensuring the integrity and comprehensiveness of the detection. At the same time, the operation panel 2 is electrically connected to the ultrasonic probe 10, and the detection result of the ultrasonic probe 10 will be displayed on the display screen inside the operation panel 2.
[0026] As a further improvement of the utility model, Figure 2 and Figure 3 As shown, the power mechanism includes a motor 16 fixedly connected to the housing 1, and the end of the main shaft of the motor 16 is connected to a gear 15, and the gear 15 is engaged with the semi-toothed ring 9. The semi-toothed ring 9 is automatically rotated on the inner side of the housing 1 by the gear 15, thereby realizing automatic adjustment of the position of the semi-toothed ring 9, without manual adjustment, and is convenient for use by staff.
[0027] As a further improvement of the utility model, Figure 1 As shown, a protective cover 11 is provided on the outer side of the motor 16 and the gear 15 , and the protective cover 11 is fixedly connected to the housing 1 . The protective cover 11 can prevent the motor 16 and the gear 15 from contacting with the staff, thereby preventing the staff from being injured by the motor 16 and the gear 15 .
[0028] As a further improvement of the utility model, Figure 2 and Figure 3As shown, the limiting mechanism includes a connecting plate 13 fixedly connected to the shell 1, an electric telescopic rod 14 is fixedly connected to the inner side of the connecting plate 13, a clamping plate 17 is fixedly connected to the other end of the electric telescopic rod 14, and the clamping plate 17 is in contact with the gear 15.
