Technical Field

[0001] This utility model belongs to the field of defect detection technology, specifically relating to a visual detection device for defects in pressure vessels. Background Technology

[0002] Pressure vessels are generally closed containers that withstand gas or liquid pressure internally or externally and have high safety requirements. They are mainly used for reactions, heat transfer, and mass transfer in production processes, or for storing and transporting gases or liquefied gases under pressure.

[0003] Most existing pressure vessels are cylindrical, and due to long-term exposure to high pressure, their surfaces are prone to dents. Therefore, pressure testing equipment is often needed to detect whether there are dents on the surface of pressure vessels.

[0004] Therefore, a visual inspection device for pressure vessel defects was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a visual inspection device for pressure vessel defects. When inspecting the surface of a pressure vessel, the angle of the inspection head can be adjusted to expand the inspection range, and detected dents can be marked for convenient subsequent processing.

[0008] The detection component includes a limiting plate disposed above the first annular plate, and a detection head is slidably connected to the surface of the limiting plate.

[0009] In a preferred embodiment of the pressure vessel defect visualization detection device of this utility model, a guide column is fixedly connected to the surface of the base plate, the guide column is slidably connected to the connecting plate, a first motor is mounted on the surface of one of the connecting plates, a rotating shaft is fixedly connected to the output shaft of the first motor, a gear is fixedly connected to the surface of the rotating shaft, the rotating shaft is rotatably connected to the connecting plate, a second annular plate is provided on the surface of the first annular plate, a toothed ring is fixedly connected to the surface of the second annular plate, and the toothed ring meshes with the gear.

[0010] As a preferred embodiment of the pressure vessel defect visualization detection device of this utility model, a ring is fixedly connected to the bottom surface of the second annular plate, and an annular groove matching the ring is formed on the surface of the first annular plate.

[0011] In a preferred embodiment of the pressure vessel defect visualization detection device of this utility model, a column and a support plate are fixedly connected to the surface of the second annular plate, and an mounting plate is fixedly connected to the upper end of the column and the support plate, and a limit plate is slidably connected to the surface of the mounting plate.

[0012] As a preferred embodiment of the pressure vessel defect visualization detection device of this utility model, the bottom surface of the limiting plate is fixedly connected to a limiting strip, and the surface of the mounting plate is provided with a sliding groove that matches the limiting strip.

[0013] As a preferred embodiment of the pressure vessel defect visualization detection device of this utility model, a spring pin is installed on the surface of the limiting plate, and a plurality of positioning holes adapted to the spring pin are opened on the surface of the mounting plate.

[0064] Working Principle: The base plate 21 serves as a platform for mounting other components. A cylinder 24 is mounted on the surface of the base plate 21. The extension shaft of the cylinder 24 can extend and retract, and its end is fixedly connected to a connecting plate 23. The extension and retraction of the cylinder 24 can drive the connecting plate 23 to move. A first annular plate 28 is fixedly connected between the two connecting plates 23.

A limiting strip 39 is fixedly connected to the bottom surface of the limiting plate 34. A groove 310 matching the limiting strip 39 is formed on the surface of the mounting plate 33. The cooperation between the limiting strip 39 and the groove 310 further limits the movement direction of the limiting plate 34, ensuring that the limiting plate 34 can only slide along the direction of the groove 310 on the mounting plate 33. A spring pin 311 is mounted on the surface of the limiting plate 34, and several positioning holes 312 that match the spring pin 311 are formed on the surface of the mounting plate 33. The spring pin 311 can be inserted into the positioning holes 312 on the mounting plate 33 to fix the position of the limiting plate 34 on the mounting plate 33. When the position of the limiting plate 34 needs to be adjusted, the spring pin 311 can be pulled out, adjusted, and then inserted into the appropriate positioning hole 312 to achieve flexible adjustment and fixation of the position of the limiting plate 34. With this design, the detection head 35 can flexibly change its distance from the pressure vessel to further adapt to pressure vessels of different shapes. The surface of the limiting plate 34 is equipped with a roller brush 315 through the stand 313, and the roller brush 315 is located below the detection head 35.The roller brush 315 may be used to process areas inspected by the detection head 35, such as cleaning or marking.

The second motor 38 provides power to the roller brush 315, driving it to rotate. A pigment tank 314 is fixedly connected to the surface of the limiting plate 34 below the roller brush 315. The pigment tank 314 is used to store pigment. During rotation, the roller brush 315 can pick up pigment to mark defective areas of the pressure vessel, making the defects visible.
