Embodiment

[0139] An auxiliary turn-over device for a tube bundle assembly of the present invention is applied to the turn-over process of the tube bundle assembly in the production process of the waste heat discharge heat exchanger of the ACP1000 nuclear power project.

[0140] Wherein, in the tube bundle assembly auxiliary turning device adopted in this embodiment, the bottom plate 11 of the main frame is a stainless steel plate, and a short square tube 15 is welded on the lower surface, such as Figure 4 shown.

[0141] Four rectangular tubes 12 are arranged on the upper surface of the bottom plate, and the four rectangular tubes 12 form a cuboid frame on the bottom plate 11 . On the second side and the fourth side of the cuboid frame, a plurality of oblique pipes 13 are welded, and at both ends of the second side and the fourth side, the included angle between the oblique pipe 13 and the rectangular pipe 12 is 90° °, the angle a between the remaining rhombic tubes 13 and the rectang...

Abstract

The invention discloses an auxiliary turnover device for a tube bundle assembly. The device mainly comprises a main frame and a baffle plate supporting assembly. The auxiliary turnover device for thetube bundle assembly is simple in structure, good in safety, convenient to assemble and disassemble and high in flexibility. Turnover operation of the tube bundle assembly can be stably completed before the tube plate and the tube bundle are welded and the purpose of erecting the tube bundle assembly is achieved.

Description

technical field [0001] The invention relates to an auxiliary turning device for the tube bundle assembly when the tube bundle assembly and the shell assembly are vertically assembled during the production and manufacturing process of the shell-and-tube heat exchanger, especially the tube bundle assembly and the shell of the shell-and-tube heat exchanger in the field of nuclear power Auxiliary turn-over device for tube bundle components during component assembly. Background technique [0002] Shell and tube heat exchangers have a wide range of applications, mainly in nuclear power, chemical machinery and other industrial fields. In the manufacturing process of shell-and-tube heat exchangers, especially in the manufacturing process of shell-and-tube heat exchangers in nuclear power projects, the assembly of tube bundle components and shell components is a very important process content, which is very important for the cleanliness of products. And the surface quality of produc...
