Holding clamp type radiation source adjusting support and method

Abstract

The invention provides a holding clamp type radiation source adjusting support. The radiation source adjusting support comprises a support base, an up-and-down movement mechanism, a horizontal movement mechanism, a telescopic arm and a clamping part, wherein the support base is vertically arranged; the up-and-down movement mechanism is detachably and fixedly arranged on the periphery of the support base in a sleeving mode, a plurality of areas of the bottom of the up-and-down movement mechanism horizontally extend outwards to form bearing parts, and multiple areas of the top of the up-and-down movement mechanism horizontally extend outwards to form limiting parts; The horizontal movement mechanism is arranged on the periphery of the up-down movement mechanism in a surrounding mode and can horizontally rotate around the center axis of the horizontal movement mechanism, the horizontal movement mechanism is located among the bearing parts and the limiting parts, and the horizontal movement mechanism is prevented from generating displacement in the vertical direction through the bearing parts and the limiting parts; the first end of the telescopic arm is fixedly connected with the outer wall of the horizontal movement mechanism, and the second end of the telescopic arm can do telescopic movement in the horizontal direction; and the clamping part is arranged at the second end of the telescopic arm and is used for clamping a radiation source. The invention also provides a radiographic detection method.

Description

technical field [0001] The invention relates to the technical field of a ray source fixing device for ray center exposure, in particular to a clamp-type ray source adjustment bracket and method. Background technique [0002] The connection between pressure vessels and pipelines of nuclear power equipment must be welded on site at the installation location, such as the connection between nuclear power plant reactor pressure vessels and main pipelines. Due to the limitations of the welding process and the site environment, the weld seam has become the weak link of the entire pressure vessel and piping system. In order to ensure the safety of the system operation, regular in-service non-destructive testing must be carried out on the weld seam. Radiographic testing is a frequently used in-service non-destructive testing method. Radiographic negatives are usually arranged outside the weld of the pipeline, and the radioactive source is placed inside the weld of the pipeline to pe...
