Large-diameter heat exchanger inner sleeve assembling and disassembling tool and using method thereof

Abstract

The invention discloses a large-diameter heat exchanger inner sleeve assembling and disassembling tool and a using method thereof and belongs to the field of manufacturing of heat exchangers. The problem that in the prior art, operation is difficult and not safe is solved. The tool, that is the inner sleeve assembling and disassembling tool assembly (2) is composed of a connecting plate (3), a ribplate (4), a reinforcing plate (5), moving lifting lugs (6) and a balance bar (7), wherein the connecting plate (3), the rib plate (4), the reinforcing plate (5) and the balance bar (7) are installedand welded into a whole, and the moving lifting lugs (6) are arranged on the balance bar (7) in a sleeving mode and can move; and bolt holes which formed in the periphery of the connecting plate (3)are matched with bolt holes of an inner sleeve assembly (1). The using method of the tool includes the steps that the moving lifting lugs (6) on the inner sleeve assembling and disassembling tool assembly (2) are connected with a steel wire rope to be connected with a top hoist; the hoist is adopted to parallelly move so as to pull the inner sleeve assembling and disassembling tool assembly (2) into a shell, the connecting plate (3) is in bolt connection with the inner sleeve assembly (1), and thus an inner sleeve is stressed uniformly to go into and come out of the shell; and assembling or disassembling of the inner sleeve is performed. By means of the tool, assembling is easy, operation is simple and convenient, the universality is high, and reutilization can be achieved.

Description

technical field [0001] The invention belongs to the field of heat exchanger manufacturing and relates to the assembly and disassembly of inner sleeves. Background technique [0002] Heat exchanger is one of the widely used unit equipment in chemical industry, petroleum, pharmaceutical and energy industries. In recent years, it adapts to the large-scale complete equipment, and the heat exchanger is also developing to large-scale. Manufacturing and installation put forward higher requirements. The internal parts of large-diameter heat exchangers have complex structures. During the assembly and disassembly process, due to the large diameter of the inner sleeve, the weight is too heavy, and the internal space is limited, there are difficulties in operation, greater danger, and easy damage to the inner sleeve. question.
