Description

Technical Field

[0001] The utility model relates to the technical field of metal pipelines, in particular to a small metal pipeline inner wall detection device. Background Art

[0002] After metal pipes are produced, they are usually inspected for cracks to determine whether the pipes are qualified. The factory usually uses penetrant testing to conduct crack inspections.

[0003] However, due to the small inner diameter of some small-sized pipes, it is difficult for workers to spray the inner wall with penetrant. Even after spraying, due to space limitations, it is difficult to thoroughly clean away the excess penetrant and evenly apply the developer to clearly show the defects. Utility Model Content

[0004] The utility model aims to provide a small metal pipe inner wall detection device to solve the above problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A small metal pipe inner wall detection device includes a workbench with a hollow internal structure, a fixed plate is provided on the upper surface of the workbench, and circular holes are provided on the fixed plate and the workbench. A first electric push rod is fixedly installed on the inner bottom wall of the workbench corresponding to the circular hole, and a mounting block is fixedly installed on the movable end of the first electric push rod. A camera and an ultrasonic detector are respectively installed on the top surface and the four sides of the mounting block.

[0007] The beneficial effects of the present invention are as follows: after the pipe to be inspected is vertically placed in correspondence with the circular hole on the workbench, the first electric push rod is activated, thereby driving the mounting block to extend through the circular hole into the interior of the pipe, and a preliminary inspection of the inner wall of the pipe is performed through the camera. When cracks are present, the location and form of obvious defects such as cracks are directly observed and recorded. Then, for areas that are difficult for the camera to observe or parts that require more detailed inspection, an ultrasonic detector is used to further confirm and quantify them. By combining the two inspection methods, a more comprehensive and accurate assessment of the health of the inner wall of the metal pipe can be made. At the same time, the mounting block is relatively small in size and can be easily inserted into the interior of the pipe, making it suitable for small-sized pipe inspection, saving time and effort, and being easy and convenient, effectively avoiding the disadvantage that the existing penetrant inspection method is difficult to apply to small-sized pipe inspection.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, fixing parts are provided on the surfaces of the fixed plate and the opposite side of the workbench; the fixing parts include a fixing ring fixedly installed on the workbench or the fixed plate with the circular hole as the center of the circle, and second electric push rods are fixedly installed on both sides of the fixing ring. The output end of the second electric push rod can move horizontally through the fixing ring and is fixedly installed with a limit ring, and a rubber pad is fixedly installed on the inner wall of the limit ring.

[0010] Furthermore, support columns are fixedly installed on all four sides of the top surface of the workbench, and a top plate is fixedly installed on the other ends of the four support columns. Several third electric push rods are fixedly installed on the upper surface of the top plate, and the movable ends of several third electric push rods are vertically movable through the top plate and fixedly connected to the upper surface of the fixed plate.

[0011] Furthermore, the front of the workbench is an open structure and a mounting frame is detachably mounted on the front, and a dustproof net is fixedly mounted on the inner wall of the mounting frame.

[0012] Furthermore, a battery is fixedly mounted on the inner bottom wall of the workbench and located on one side of the first electric push rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 4As shown, embodiment 1 of the utility model is a small metal pipe inner wall detection device, including a workbench 1 with a hollow structure inside, a fixing plate 2 is provided on the upper surface of the workbench 1, and circular holes 3 are provided on the fixing plate 2 and the workbench 1, and a first electric push rod 4 is fixedly installed on the inner bottom wall of the workbench 1 corresponding to the circular hole 3, and the movable end of the first electric push rod 4 extends into the circular hole 3 below and is fixedly installed with a mounting block 5, and a camera 6 and an ultrasonic detector 7 are respectively installed on the top surface and the surrounding sides of the mounting block 5.

[0021] After the pipe to be inspected is vertically placed in correspondence with the circular hole 3 on the workbench 1, the first electric push rod 4 is activated, thereby driving the mounting block 5 to extend into the interior of the pipe through the circular hole 3. A preliminary inspection of the inner wall of the pipe is performed using the camera 6. When cracks are present, the location and form of obvious defects such as cracks are directly observed and recorded. Then, for areas that are difficult for the camera 6 to observe or parts that require more detailed inspection, an ultrasonic detector 7 is used to further confirm and quantify the areas. By combining the two inspection methods, a more comprehensive and accurate assessment of the health of the inner wall of the metal pipe can be made. At the same time, the mounting block 5 is relatively small and can be easily inserted into the interior of the pipe, making it suitable for small-sized pipe inspection, saving time and effort, and being easy and convenient. This effectively avoids the drawback of existing penetrant inspection methods that are difficult to apply to small-sized pipe inspections.

[0022] Example 2 of the present invention is a small metal pipe inner wall detection device. On the basis of Example 1, a fixing part 8 is provided on the surface of the fixed plate 2 on the opposite side of the workbench 1; the fixing part 8 includes a fixing ring 81 fixedly installed on the workbench 1 or the fixed plate 2 with the circular hole 3 as the center of the circle, and a second electric push rod 82 is fixedly installed on both sides of the fixing ring 81. The output end of the second electric push rod 82 moves horizontally through the fixing ring 81 and is fixedly installed with a limit ring 83, and a rubber pad 84 is fixedly installed on the inner wall of the limit ring 83.

[0023] After the pipe is placed, the second electric push rod 82 is started, thereby driving the limit ring 83 to limit the two ends of the pipe, preventing the pipe from tipping over during inspection; by setting the rubber pad 84, while protecting the surface of the pipe, the limit ring 83 can limit and fix pipes of different sizes due to its own softness.

[0024] Example 3 of the present utility model is a small metal pipe inner wall detection device. On the basis of Example 1 or 2, support columns 9 are fixedly installed on all four sides of the top surface of the workbench 1, and a top plate 10 is fixedly installed on the other ends of the four support columns 9. A plurality of third electric push rods 11 are fixedly installed on the upper surface of the top plate 10, and the movable ends of the plurality of third electric push rods 11 are vertically movable and penetrate the top plate 10 and are fixedly connected to the upper surface of the fixed plate 2.

[0025] By adjusting the third electric push rod 11, detection of pipelines of different lengths can be achieved.

[0026] Embodiment 4 of the present invention is a small metal pipe inner wall detection device. Based on any one of embodiments 1 to 3, the front of the workbench 1 is an open structure and a mounting frame 12 is detachably installed on the front, and a dustproof net 13 is fixedly installed on the inner wall of the mounting frame 12.

[0027] By setting the workbench 1 as an open structure, the inside of the workbench 1 can be ventilated with the outside, thereby dissipating heat from the inside of the workbench 1. By setting the dustproof net 13, external dust is prevented from entering the workbench 1, thereby preventing the operation of the first electric push rod 4 from being affected.

[0028] Embodiment 5 of the present invention is a small metal pipe inner wall detection device. Based on any one of embodiments 1 to 4, a battery 14 is fixedly installed on the inner bottom wall of the workbench 1 and on one side of the first electric push rod 4.
