Auxiliary device for turning over large cylinders

Abstract

The invention provides an auxiliary device for overturning a large-sized barrel and relates to an auxiliary device for vertically overturning a large-sized pressure vessel. The auxiliary device comprises a bearing baseplate, two arc-shaped overturning structures, a connecting and fixing structure and a lifting structure, wherein the two arc-shaped overturning structures are mounted on two sides of the lower part the bearing baseplate respectively; the connecting and fixing structure is mounted in the middle of the upper part of the bearing baseplate; and the lifting structure is mounted on the bearing baseplate. The auxiliary device provided by the invention has the characteristics of having a novel and compact structure, occupying a small area, being convenient to disassemble, assemble and store, low in cost and suitable for overturning large-sized barrels with similar structures, having high safety and reliability, being capable of being used repeatedly, and the like. Therefore, the auxiliary device is a novel auxiliary device for overturning the large-sized barrels, which integrates economy and practicability.

Description

technical field [0001] The auxiliary device for turning over a large cylinder according to the invention relates to an auxiliary device for vertical turning over of a large pressure vessel. Background technique [0002] After completing the welding task of the body weldment, the outer shell of a large pressure vessel needs to be turned from a horizontal state to a vertical state in order to enter the pit for the next step of internal component installation. Since the overall length of the shell is 16 meters and the total weight is 160 tons, and the two ends of the shell are respectively the plane of the bottom of the cylinder and the plane of the end of the connecting pipe. It is very dangerous to use tools such as lifting lugs and wire ropes to perform aerial flipping. In view of the fact that the shell length is 16 meters, if redesigning a set of common L-shaped cylinder turning brackets for turning over, it not only occupies a large area, but also requires a lot of mater...

AI Technical Summary

Problems solved by technology

It is used to solve the inability of the existing technology to realize the overturning task of the large pressure vessel shell, or to design a common L-shaped whole-body overturning bracket to overturn the 16-meter-long pressure vessel, but there are problems such as large floor space, many consumables, and high cost.
