Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pressure vessels, in particular to a pressure vessel in-place guiding device. BACKGROUND

[0002] A pressure vessel is a closed container that can withstand pressure. Pressure vessels are used in a wide range of applications, and they play an important role and function in many departments such as industry, civil, military, and many fields of scientific research. Among them, the most used are in the chemical industry and petrochemical industry, and the pressure vessels used in the petrochemical industry account for about 50% of the total number of pressure vessels. In the chemical and petrochemical industries, pressure vessels are mainly used for heat transfer, mass transfer, reaction, and other process, as well as storage and transportation of pressurized gas or liquefied gas. In other industrial and civil fields, they are also widely used, such as air compressors, various special-purpose compressors, and refrigeration compressor auxiliaries (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.).

[0003] The prior art such as application number "202021298944.9" discloses a pressure vessel in-place guiding mechanism, which comprises a working plate, the lower surface of the working plate is fixedly connected with locking universal wheels at four corners, and symmetrically distributed grooves are formed in the working plate. The in-place guiding mechanism is arranged in the groove, which can adjust the height and horizontal position of the ring-shaped limiting plate in time through the adjustment of the rotating motor and the telescopic rod, so that the device can limit and protect the descending pressure vessel, which not only can reduce the error between the landing position of the pressure vessel and the expected position, but also can effectively prevent the pressure vessel from shaking and tilting during the descending process, thereby facilitating the precise positioning and installation of the pressure vessel.

[0004] The above technical scheme adjusts the position of the limiting plate through the setting of the lead screw and the rotating motor, so that the pressure vessel can be directly clamped and fixed. The telescopic rod can adjust the height, so that the pressure vessel can be limited and stabilized during the descending process to avoid shaking and tilting. However, in actual use, after the pressure vessel is clamped and fixed by the limiting plate, it is difficult to ensure that the center point of the pressure vessel is consistent with the center point of the thermal insulation layer of the nuclear island plant. Therefore, after the clamping and fixing is completed, the whole device needs to be moved and adjusted. During the alignment process, it needs to be constantly checked in all directions, mainly relying on the naked eye, so that it is difficult to accurately position it, and it also takes a long time to calibrate.

[0005] The prior art has not yet proposed an effective solution to the problems.

[0006] Therefore, in order to solve the above problems, the application provides a pressure vessel in-place guiding device. SUMMARY
