(EN) Device for nondestructively testing structures by gammagraphy
(ZH) 用于通过伽马射线照相来无损检测结构的装置
Abrégé
(EN) A gammagraphy device (1) is proposed comprising: a housing (3) having a firing orifice (10) allowing ionizing radiation to be transmitted out of the housing (3); a holding hoop (5) intended to tightlyencircle a structure (T) to be analysed; and means for removably fastening the housing (3) to the hoop (5) comprising a plurality of fastening elements (52) for fastening the housing (3) in preset and different angular positions around the hoop (5), the firing orifice (10) being designed to direct the ionizing radiation onto the structure (T) when the structure is tightly encircled by the hoop (5) and the housing (3) is fastened to the hoop (5) by one of the fastening elements.
(ZH) 提出了一种伽马射线照相装置(1),其包括:壳体(3),其具有允许将电离辐射发射到壳体(3)之外的击发孔(10);保持卡箍(5),其旨在紧紧地包围待分析结构(T);以及用于将壳体(3)可移除地紧固到卡箍(5)的装置,其包括用于将壳体(3)紧固在卡箍(5)周围的预设且不同的角位置中的多个紧固元件(52),击发孔(10)设计为当结构由卡箍(5)紧紧地包围且壳体(3)通过一个紧固元件紧固到卡箍(5)时将电离辐射引导到结构(T)上。
