Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The frame is the basic structural part of the entire mechanical device, which undertakes the task of loading the entire moving parts. The performance of the frame affects the scanning speed and accuracy of the entire mechanical device.

[0025] A nuclear reactor pressure vessel self-expanding frame structure such as figure 1 , 2 As shown, the structure is composed of a central cylinder 1, a frame assembly 2 and a support foot 8, and the frame assembly 2 and the support foot 8 are installed as a set and then installed together with the central cylinder 1. The central cylinder 1 and the frame assembly 2 are connected by plugging and fastened with bolts 7 .

[0026] The central cylinder 1 is welded by stainless steel, and is mainly composed of a central cylinder, upper and lower cover plates and some supporting ribs. The upper...

Abstract

Belonging to the technical field of non-destructive detection, the invention in particular relates to a nuclear reactor pressure vessel self-expanding frame. The frame consists of: a lower end plug, acentral cylinder body, a frame component and support legs. The frame component and support legs are installed into a complete set, and then the whole set and the central cylinder body are mounted together. The central cylinder body and the frame component are connected by insert connection and are fixed by a bolt. The central cylinder body comprises a central cylinder, an upper cover plate and alower cover plate, and some support rib plates. Four circumferential connection plates are evenly arranged around the central cylinder body for abutment joint of the frame component and the central cylinder body. The structure adopts a hinge design to improve the convenience and flexibility of the frame; the support legs of the frame adopt a telescopic structure, thus reducing the space occupationof the equipment; and the interface design of the central cylinder body makes the connection with an inspection apparatus convenient and reliable.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to an autonomously deployable frame of a nuclear reactor pressure vessel. Background technique [0002] During the operation of nuclear power plants, the reactor pressure vessel is in an environment of high temperature, high pressure, and high radiation. As the operating time increases, the metal properties of the container material will gradually decrease, and metal discontinuity will also occur. Therefore, it is very necessary to control the pressure. Containers are inspected to detect dangerous defects in time, so that they can be dealt with as soon as possible, so as to maintain and ensure the safety of nuclear power facilities, and avoid serious safe operation and nuclear leakage accidents. [0003] The newly developed self-expandable frame overcomes the previous characteristics of large space occupation and inflexibility. On the basis of ensuring th...
