Embodiment Construction

[0027] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] A positioning connection structure for connecting the follower assembly and the absorber assembly of the control rod drive line of China Advanced Research Reactor. The lower end of the absorber assembly 1 is a square cylindrical structure, and a spring hook 4 is fixed on the inner walls opposite to each other. , the absorber assembly 3 and the follower assembly 1 are positioned and connected by the spring hook 4, such as figure 1 shown. There is an arc-shaped protrusion 18 on the other two opposite inner walls of the lower end of the absorber assembly 1, such as Figure 9 shown.

[0029] Such as figure 2 and image 3 As shown, the spring hook 4 is composed of a spring hook main body 9 and a spring hook body 7 below it, wherein the spring hook body 7 protrudes from the bottom of the absorber assembly 1 . The spring hook body 9 i...

Abstract

The invention belongs to the technical field of nuclear reactors and particularly relates to a positioning connection structure of a follower assembly and an absorber assembly of a control rod driving wire of a nuclear reactor, which comprises a follower assembly and an absorber assembly, spring hooks are fixedly arranged on the opposite inner walls at two sides of the lower end of the absorber assembly, clamping holes matched with the spring hooks are arranged in the opposite inner walls at two sides of the upper end of the follower assembly, and the spring hooks and the clamping holes are matched to realize positioning connection between the follower assembly and the absorber assembly. Each spring hook comprises a main body and a hook body below the main body, the main body of each spring hook is provided with a screw hole, each hook body comprises a protruding block on the inner side as well as an upper claming hook and a lower clamping hook on the outer side, and the upper clamping hook is narrower than the lower clamping hook; and the lower clamping hooks are matched with the clamping holes. In the technical scheme provided by the invention, the follower assembly and the absorber assembly are connected into a whole, and the advantages of compactness for connection, accuracy for positioning, appropriate elastic force, convenience for operation and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactors, and in particular relates to a positioning connection structure of a follower assembly and an absorber assembly of a control rod driving line of a nuclear reactor. Background technique [0002] The China Advanced Research Reactor (CARR) control rod drive line is composed of absorber assembly, follower assembly, square cone, connecting rod, armature and other components from top to bottom, and these components are sequentially connected into a whole. Among them, the following body assembly is an irregular replacement part, and it is operated remotely under water. In the process of installation and disassembly, it is necessary to prevent misinsertion and fall-off of components and ensure safety and accuracy. Therefore, the positioning connection structure between the follower component and the absorber component is required to have high reliability. Contents of the invention [0003] (1...
