[0002] A pressure vessel is a closed container that can withstand pressure. It is mainly used to hold gas or liquid and bear a certain pressure. It plays an important role in many fields of industry, civil, military and scientific research. According to its use and working characteristics, pressure vessels can be divided into many types, such as reaction pressure vessels, heat exchange pressure vessels, separation pressure vessels and storage pressure vessels.
[0003] In order to ensure the safe operation of pressure vessels, a series of safety regulations and operating procedures need to be followed, including regular external and internal inspections, leak tests, etc., to ensure the integrity of the pressure vessels. Existing pressure vessels are generally subjected to air tightness tests and inner wall thickness tests after production to determine whether they meet the use standards. Existing pressure vessel thickness tests are generally performed manually, which is troublesome to measure and inconvenient to perform thickness tests on the internal rear end of the pressure vessel.
[0004] To this end, a pressure vessel detection device is proposed. Utility Model Content

[0010] Through the above technical solution, when in use, one of the mounting rods is inserted into the pressure vessel along the inlet of the pressure vessel to be inspected and placed in the pressure vessel, and the other mounting rod is located on the outer surface of the pressure vessel. Then, starting the first servo motor can drive the first threaded rod to rotate, and the rotation of the first threaded rod can drive the two mounting rods to move relative to each other, so as to achieve the effect of relative movement of the two measuring rods. When one end of the two measuring rods contacts the inner surface and the outer surface of the pressure vessel respectively, the reading of the corresponding position of the mounting rod on the scale bar on the side of the mounting block is recorded at this time, that is, the effect of conveniently measuring the inner wall thickness of the pressure vessel can be achieved, and the thickness of the remaining inner wall and the rear end of the pressure vessel can be measured by moving the position of the device.
[0011] Furthermore, the adjustment assembly includes a second servo motor installed on the upper end of the mounting column and a second threaded rod installed on the output end of the second servo motor.
