Turning tooling and use method thereof

Abstract

The invention provides a turning tooling for a nuclear generation IV high-temperature gas-cooled reactor pressure vessel assembly, comprising a bottom support and a turning lifting beam; the bottom support is fixedly connected to the ground, and a rail matching a trunnion of the vessel assembly is arranged at the top of the bottom support; the vessel assembly is supported by placing the trunnion on the rail; the turning lifting beam is fixedly connected to the vessel assembly through a screw hole in one end surface of the vessel assembly; a running hook is fixedly connected to the turning lifting beam, and the external force is applied to the turning lifting beam, so that the turning lifting beam and the vessel assembly are integrally turned around the trunnion. The invention also discloses a use method of the turning tooling. According to the invention, the problem that the vessel assembly cannot be turned over under the conditions of large size, heavy weight and limited plant heightis solved, and the stability and safety of the vessel assembly during turning over are ensured. The turning tooling of the invention has the advantages of simple structure, easy assembly and disassembly, and high practical value.

Description

technical field [0001] The invention relates to a tooling, in particular to a tooling for turning over the pressure vessel components of the fourth-generation nuclear high-temperature gas-cooled reactor. Background technique [0002] The fourth-generation nuclear high-temperature gas-cooled reactor pressure vessel assembly has an overall size of 23m×φ5.7m and a weight of 570 tons. After the container assembly is manufactured, a vertical hydrostatic test is required. During the manufacturing process, the container assembly is in the horizontal position, and before the vertical hydraulic test, it needs to be turned over to the vertical position, and lifted to the deep pit for the hydraulic test for the hydraulic test. [0003] like figure 1 As shown, the container assembly has a cylindrical structure with both ends closed, including a main flange of the cylinder, an upper cylinder, a lower cylinder and a lower head that are coaxial and fixedly connected in sequence. The mai...
