Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel inspection, and in particular relates to an operating table for pressure vessel inspection. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses and plays an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most widely used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other process processes, 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 types of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporator liquid coolant storage tanks, etc.) are all pressure vessels.

[0003] In the prior art, there is a pressure vessel inspection placement table with a patent announcement number of CN 213858935 U. The above patent can effectively fix the pressure vessel during inspection, avoid the problem of position change of the pressure vessel during inspection, avoid the impact on inspection efficiency, and reduce safety hazards. However, there are still the following shortcomings in actual use: From a practical point of view, some pressure vessels are large in size and heavy in weight, and it is difficult for workers to place the pressure vessel on the operating table alone. Multiple workers are required to lift it together, which increases the workload and reduces labor efficiency. Moreover, the operating table can only be fixed in a certain place for use, and cannot be moved according to the specific position of the pressure vessel for inspection, which reduces the scope of application of the operating table.

[0004] Therefore, there is a need for an operating table for pressure vessel inspection to solve the problems in the prior art that it is difficult to place a large-volume pressure vessel on the operating table alone and that the pressure vessel cannot be moved according to its specific position.

[0025] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that there are two connecting blocks 505, which are symmetrically arranged front and back.

[0026] By providing the inverted U-shaped plate 509 , the inverted U-shaped plate 509 can be kept balanced during the process of the cylinder 507 driving the inverted U-shaped plate 509 to rise and fall, thereby ensuring the movement stability of the inverted U-shaped plate 509 .

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the rotating shaft 511 is symmetrically connected to the inner two sides of the inverted U-shaped plate 509, the pressing plate 512 is fixedly connected to the side of the rotating shaft 511 close to the pressure vessel body 6, the pressure vessel body 6 is arranged between the two pressing plates 512, the third motor 510 is fixedly connected to the front side of the inverted U-shaped plate 509, and the output end of the third motor 510 is connected to the rotating shaft 511;

[0028] When the cylinder 507 drives the pressure vessel body 6 to move up to a certain height, the third motor 510 is controlled to drive the rotating shaft 511 to rotate, and the rear rotating shaft 511 is driven to rotate by clamping the fixed pressure vessel body 6, so that the pressure vessel body 6 can be rotated ninety degrees and then moved to the top of the operating table 3.

[0029] According to the above working process, it can be known that: through the provided lifting mechanism 5, the pressure vessel body 6 placed on the ground can be lifted, moved to a certain height, rotated ninety degrees, and then moved above the operating table 3, thereby reducing the workload of the staff and improving labor efficiency.

[0033] The present solution has the following working process: when in use, after the universal wheel 102 drives the whole to move to the required position, the first motor 103 is controlled to drive the worm gear 104 to rotate, and the gear 106 is driven to rotate through the transmission shaft 105. Since the gear 106 is meshed and rotated with the rack 109, the fixed column 107 is driven to move downward until the fixed seat 108 contacts the bottom surface, so that the whole is fixed on the ground; then the inverted U-shaped plate 509 is driven downward by the cylinder 507 until the pressure vessel body 6 is inside the two pressure plates 512, and the pressure plates 512 press against the pressure The pressure vessel body 6 is fixed, and then the cylinder 507 is controlled to drive the inverted U-shaped plate 509 to move upward, thereby driving the pressure vessel body 6 to move upward. After moving to a certain height, the third motor 510 is controlled to drive the rotating shaft 511 to rotate, and the rear rotating shaft 511 is driven to rotate by clamping the fixed pressure vessel body 6, so that the pressure vessel body 6 can be rotated ninety degrees, and then the second motor 502 drives the screw rod 503 to rotate, and the connecting plate 506 is driven to move toward the direction of the operating table 3 through the connecting block 505, and the pressure vessel body 6 is moved above the operating table 3.
