[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used and play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, they are most used in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about half of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used in process such as heat transfer, mass transfer, reaction, as well as storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fields, such as air compressors, various special compressors and auxiliary machines of refrigeration compressors, coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc. are all pressure vessels.

In this embodiment, the third motor 25 drives the rubber wheel 26 to rotate, and the rubber wheel 26 drives the container to rotate.

[0034] The implementation principle of this embodiment is:

[0035] When it is necessary to load and unload the container, the container is first placed on the top of the roller 6, and then the first motor 14 starts working, and the transmission wheel 15 drives the transmission belt 16 to rotate. When the outer surface of the container contacts the transmission belt 16, the container is lifted by the auxiliary ball 13 on the top of the support plate 12. When the transmission belt 16 is used to drive the container to move on the top of the roller 6, the auxiliary ball 13 will support the internal rotation of the support plate 12, which plays a role in reducing friction. The electric push rod 11 can control the height of the auxiliary ball 13 and the transmission belt 16. After the container moves to the appropriate position, the electric push rod 11 begins to retract, so that the auxiliary ball 13 and the transmission belt 16 are away from the container, and then the container will stay on the top of the roller 6, waiting for wall thickness detection. When the detection is completed, the transmission belt 16 is used to drive the container away from the rubber wheel 26, and then the hydraulic rod 3 begins to retract, forming a height difference between the two rollers 6 to facilitate unloading of the container;

[0036] When the wall thickness is detected, the second motor 18 starts working and drives the threaded rod 19 to rotate. The threaded rod 19 is used in conjunction with the threaded sleeve 20 to drive the lifting block 21 to slide up and down. While the lifting block 21 slides up and down, the limit slider 22 will slide on the outside of the guide rod 23 to play a limiting role. The threaded rod 19 and the threaded sleeve 20 are used in conjunction to control the rubber wheel 26 to fit on the inner wall of the container and fix the container so as to detect the wall thickness of the container. When the single-point detection is completed, the third motor 25 starts working to drive the rubber wheel 26 to rotate. The rubber wheel 26 is used to drive the container to rotate for a fixed stroke so as to perform multi-position detection to ensure that the wall thickness meets the qualified standard. Since the roller 6 is provided at the bottom of the container, it assists the rubber wheel 26 in driving the container to rotate.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] By cooperating with the connecting frame 5, the mounting frame 2 and the roller 6, the container is facilitated to roll. By cooperating with the third motor 25 and the rubber wheel 26, the container is driven to rotate. By the second motor 18, the threaded rod 19 and the lifting block 21, the rubber wheel 26 is controlled to fit the inner wall of the container. By using the above structure, the container can be controlled to rotate during measurement, thereby realizing multi-position measurement and making the detection data more accurate. By cooperating with the hydraulic rod 3, the mounting plate 4 and the connecting frame 5, the roller 6 is driven to rise and fall. By adding the electric push rod 11, the auxiliary ball 13 is driven to rise and fall. By cooperating with the support plate 12 and the auxiliary ball 13, the container is facilitated to slide. By cooperating with the first motor 14, the transmission wheel 15 and the transmission belt 16, the container is driven to slide. By using the above structure, containers can be loaded and unloaded quickly and conveniently, thereby improving work efficiency.
