Bearing turntable for steering of large pressure vessel

Abstract

The invention discloses a bearing turntable for steering of a large pressure vessel, which comprises a slewing bearing, the slewing bearing comprises an inner ring and an outer ring, a rolling body is arranged between the inner ring and the outer ring, the inner ring fixes the outer ring and plays a supporting role, and the outer ring rotates on the inner ring. The lower surface of the inner ring is connected with a lower mounting plate, four corners of the bottom surface of the lower mounting plate are respectively provided with a universal wheel, the upper surface of the outer ring is connected with an upper mounting plate, the upper mounting plate is provided with a lifting mechanism, and the lifting mechanism is connected with a saddle of the pressure vessel. The slewing bearing serves as a main component and can bear large axial and radial loads and overturning moment at the same time, the oil duct and the oil nipple are arranged between the inner ring and the outer ring, the lubricating function can be well achieved, smooth rotation between the inner ring and the outer ring is guaranteed, and the universal wheels at the bottom of the device comprise the movable trundle and the fixed trundle, so that the device is convenient to use. The pressure container can move in any direction, and when parking is needed, safety can be well guaranteed.

Description

technical field [0001] The invention relates to a bearing turntable for turning a large pressure vessel. Background technique [0002] A pressure vessel is a closed container that can withstand pressure. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most used ones are in the chemical industry and the petrochemical industry, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the field of chemical industry and petrochemical industry, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fields. [0003] During the process of production and transportation of the pressure vessel, ...

AI Technical Summary

Problems solved by technology

[0003] During the production and transportation of pressure vessels, due to their large volume, it is extremely difficult to turn the pressure vessels during transportation, so there is an urgent need for a device that assists the pressure vessels to turn during transportation.
