Description

Technical Field

[0001] This utility model relates to the technical field of defect detection devices, specifically to a device for detecting defects on the inner surface of a pipeline. Background Technology

[0002] Pressure pipelines are widely used in industrial fields such as oil, natural gas, chemical, power and urban gas supply. They are key facilities for transporting various fluid media. Because pipelines are exposed to high pressure, high temperature, corrosive media and complex environments for a long time, their surfaces are prone to various defects, such as cracks, corrosion, pits and scratches. If these defects are not detected and repaired in time, they may lead to pipeline leaks, ruptures, or even serious safety accidents, causing casualties and huge economic losses.

[0003] Existing pipe internal surface defect detection devices scan the inner wall of pipes using cameras to detect defects. While this method can detect defects, it requires clamping and fixing the pipe during inspection to ensure stability. To allow the detection head to enter the pipe, one end needs to be manually pushed to avoid gaps between the pipe and the device, leading to incomplete internal inspection and wasting manpower. Furthermore, when inspecting the outer wall of the pipe, the clamping device creates blind spots, resulting in poor inspection performance. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3As shown, a pipe inner surface defect detection device in this embodiment includes a detection platform 3. A vertical plate 2 is installed on one side of the top of the detection platform 3. A motor 1 is installed in the middle of the top of the vertical plate 2. A threaded rod 17 is installed in the middle of the vertical plate 2. A sliding plate 22 is installed on the threaded rod 17. Two limiting slide rails 16 are symmetrically installed on both sides of the threaded rod 17 on the vertical plate 2. A multi-stage telescopic rod 18 is installed on one side wall of the sliding plate 22. A mounting plate 20 is fixed to the telescopic end of the multi-stage telescopic rod 18. Detection heads 19 are installed on the end of the mounting plate 20 away from the multi-stage telescopic rod 18 and at the bottom. An electric slide rail 2 4 is installed in the middle of the top of the detection platform 3. A sliding block on the electric slide rail 2 4 is connected to a limiting plate 6. A motor 2 12 is installed on the side wall of the limiting plate 6 away from the vertical plate 2. The power output end of the motor 2 12 is connected to a rotating shaft 15. A turntable 11 is connected, and a support rod 13 is installed in the middle of the turntable 11. Two hydraulic cylinders 14 are symmetrically arranged on both sides of the top of the support rod 13. The telescopic end of the hydraulic cylinder 14 is connected to a clamping plate 9. A rubber pad 10 is provided on the outer wall of the clamping plate 9. Through the design of the upper limit plate 6 of the electric slide rail 24, after the detection head 19 enters the pipeline, the upper limit plate 6 slides on the electric slide rail 24, realizing the pushing of the upper limit plate 6 on one end of the pipeline and the sliding of the pipeline on the sliding support 21. This avoids the tedious manual pushing. In addition, the hydraulic cylinder 14 drives the clamping plate 9 to move outward, realizing the contact between the rubber pad 10 on the outer wall of the clamping plate 9 and the inner wall of the pipeline. This realizes the limiting of the upper limit plate 6 on different inner walls of the pipeline, which facilitates the device to detect the outer wall of the pipeline and avoids the problem of detection blind spots caused by the clamping device.

[0024] like Figures 1-3 As shown in this embodiment, the top of the testing platform 3 is symmetrically provided with two electric slide rails 8 at both ends of the electric slide rail 2 4. The electric slide rail 8 located on one side is connected to a sliding support 21 through its own sliding block. A vertical rod 5 is provided at the middle of the top of the sliding support 21, and a rubber pad 2 7 is provided on the side wall opposite to the vertical rod 5.

[0025] like Figures 1-3 As shown, in this embodiment, the sliding support 21 is connected to the sliding block screw of the electric slide rail 8, the upright 5 is connected to the sliding support 21 by screws, and the rubber pad 7 is bonded to the upright 5. The sliding support 21 provides support for the bottom of the pipe and facilitates the sliding of the pipe at its upper end. The design of the upright 5 in conjunction with the rubber pad 7 achieves the limitation of the two sides of the pipe.

[0026] like Figures 1-3As shown, in this embodiment, the upright plate 2 is screwed to the detection table 3, the motor 1 is screwed to the upright plate 2, the motor 1 is rotatably connected to the threaded rod 17, and the slide plate 22 is threaded to the threaded rod 17. The motor 1 drives the threaded rod 17 to rotate, realizing the sliding of the threaded rod 17 on the limiting slide rail 16, thereby realizing the adjustment of the height of the slide plate 22, so as to facilitate the detection head 19 to detect the inner wall or the outside of the pipe.

[0027] like Figures 1-3 As shown, in this embodiment, the multi-stage telescopic rod 18 is screwed to the slide plate 22, the mounting plate 20 is screwed to the telescopic end of the multi-stage telescopic rod 18, and the detection head 19 is screwed to the mounting plate 20. The multi-stage telescopic rod 18 drives the detection head 19 to move forward, thereby realizing the identification and detection of defects on the inner wall of the pipeline by the detection head 19.

[0028] like Figures 1-3 As shown, in this embodiment, the electric slide rail 2 4 is screwed to the detection table 3, the limiting plate 6 is screwed to the sliding block of the electric slide rail 2 4, the motor 2 12 is keyed to the rotating shaft 15, and the rotating shaft 15 is screwed to the turntable 11. The design of the electric slide rail 2 4 facilitates the movement of the limiting plate 6 on the electric slide rail 2 4, realizing the sliding of the pipeline on the sliding support 21, so that one end of the pipeline can approach the detection head 19.

[0029] like Figures 1-3 As shown, in this embodiment, the support rod 13 is screwed to the turntable 11, the hydraulic cylinder 14 is screwed to the support rod 13, the telescopic end of the hydraulic cylinder 14 is screwed to the clamping plate 9, and the rubber pad 10 is bonded to the clamping plate 9. The support rod 13 realizes the installation and fixation of the two hydraulic cylinders 14. The hydraulic cylinder 14 drives the clamping plate 9 to move outward, realizing the clamping plate 9 clamping the inner wall of the pipe, which facilitates the rotation groove of the pipe. The design of the rubber pad 10 can effectively increase the friction between the clamping plate 9 and the pipe.

[0030] The specific implementation process of this embodiment is as follows: When using the device, the detection platform 3 needs to be placed and installed in an appropriate position, and the device needs to be connected to an external power supply. When detecting the inner wall of the pipe, the distance between the two sliding supports 21 needs to be adjusted so that the sliding supports 21 can lift and limit the bottom end of the pipe. At the same time, with the design of the two uprights 5, the pipe can be effectively limited on both sides. Then, the motor 1 drives the threaded rod 17 to rotate, realizing the sliding of the threaded rod 17 on the online slide rail, so that the mounting plate 20 of the multi-stage telescopic rod 18 can face the pipe. At the same time, the limiting plate 6 slides on the electric slide rail 2 4, realizing the limitation. The position plate 6 pushes the pipe on the sliding support 21, allowing one end of the pipe to approach the vertical plate 2, so that the multi-stage telescopic rod 18 can perform telescopic detection inside the pipe. When the hydraulic cylinder 14 drives the two clamping plates 9 to move outward, the clamping plates 9 can clamp the inner wall of the pipe. At the same time, the motor 12 drives the turntable 11 on the rotating shaft 15 to rotate, which in turn drives the clamping plates 9 to rotate, thereby realizing the rotation of the pipe. This allows the detection head 19 to fully detect the inner wall of the pipe. At the same time, when detecting the surface of the pipe, the design of the detection head 19 located at the bottom facilitates the identification and detection of the entire surface of the pipe at any time.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
