Problems solved by technology

[0005] 1. The space on the back of the weld is narrow, and artificial cloth cannot be realized
The existing mature automated patching systems are designed based on the principle of magnetic adsorption, while the raw material of the pre-researched parts in the vacuum chamber is ultra-low carbon austenitic stainless steel, which is not magnetically conductive, which limits the application of conventional patching devices
[0006] 2. The size of the pre-study parts in the vacuum chamber is huge, and the efficiency of manual handling of the radiation source for detection is low, and the installation and positioning of the radiation source are difficult. At the same time, manual handling of the radiation source also has the risk of high-altitude operations and the risk of workers being exposed to the radiation environment due to misuse

Embodiment 1

[0028] As an optimization description of the above technical solutions:

[0029] The rollers 31 at the four corners of the bottom of the flaw detection vehicle 3 include two driving wheels on one side of the bottom of the flaw detection vehicle 3 and two driven wheels on the other side of the bottom of the flaw detection vehicle 3. force and steering force. The purpose is that the cooperation between the driving mechanism and the wheel body of the flaw detection vehicle 3 can not only easily realize the driving and steering, but also has the advantage of high synchronization of the four rollers there.

Embodiment 2

[0031] As an optimization description of the above technical solutions:

[0032] Such as Figure 6As shown, the telescopic frame 331 of the cloth mechanism 33 includes four groups of X-shaped brackets, and two groups of X-shaped brackets are correspondingly arranged on two groups of X-shaped brackets of the other two groups, and the contact ends are hinged by pin shafts. The middle part is composed of hinged rods 3311, the bottom side of the two rods 3311 at the same end in the lower two groups of X-shaped brackets are all hinged on the fixing seat 3312, and the top side is slidingly installed on the side wall of the dark bag fixing plate 332 through pins. In the shaped hole, the bottom and other side of the other two rods 3311 at the same end of the lower two groups of X-shaped brackets are connected to the bar-shaped hole of the sliding seat 3313 of the cloth mechanism through the connecting shaft 3312, and the top side is fixed in the dark bag through a pin. On the side wa...

Embodiment 3

[0035] The sensor 21 is signal connected with an audible and visual alarm 22 . The purpose is to conveniently notify the operator that the flaw detection vehicle 3 has reached the set position and start to detect the longitudinal weld, so that the control is more timely and accurate.

Abstract

The invention discloses a CFETR (Chinese fusion engineering testing reactor) vacuum chamber pre-grinding piece longitudinal weld joint automatic flaw detection positioning device. The device comprisesa flaw detection vehicle capable of operating in an interlayer of an outer shell and an inner shell of a vacuum chamber pre-grinding piece; and a radiation source machine is arranged on the inner side of the inner shell. The problem that the interlayer of the inner shell and the outer shell of the CFETR vacuum chamber pre-grinding piece is difficult in sheet distribution is solved, the work riskof workers is lowered, and the flaw detection requirement of the installation site of the vacuum chamber pre-grinding piece is met.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to an automatic flaw detection and positioning device for longitudinal welds of CFETR vacuum chamber pre-study parts. Background technique [0002] "China Fusion Engineering Test Reactor" - CFETR (Chinese Fusion Engineering Testing Reactor) is an important subject to verify key scientific and technical issues of fusion reactors. CFETR is a very complex system consisting of many functional parts, among which the pre-research part of the vacuum chamber is a core part of the fusion reactor, and it is a container part that provides stable plasma operation. Heap unit operation is particularly important. The total height of the CFETR vacuum chamber pre-study parts is about 17m, and the materials are all 316L. It is a large-scale complex contour double-layer D-shaped cross-section structure. The vacuum chamber pre-study parts have extremely high requirements for welds. No...
