Description
技术领域 technical field
本发明涉及一种支架结构，属于射线探伤领域。 The invention relates to a bracket structure and belongs to the field of radiographic flaw detection.
背景技术 Background technique
X射线检测技术作为工业射线的重要手段，广泛应用于材料测试、食品检测、制造业、医学、军工等方面。X射线无损检测成像技术经历了从传统胶片成像技术、数字存储荧光体成像CR技术（Computer Radiography）和数字摄影成像DR技术(Digital Radiography)的发展过程。工业X射线机机头用于产生X射线，由于其由X射线管、升压线圈、铅皮组成，体型一般做成圆筒状，重量一般达30-50kg。 As an important means of industrial radiation, X-ray inspection technology is widely used in material testing, food testing, manufacturing, medicine, military industry, etc. X-ray nondestructive testing imaging technology has experienced the development process from traditional film imaging technology, digital storage phosphor imaging CR technology (Computer Radiography) and digital photography imaging DR technology (Digital Radiography). The head of an industrial X-ray machine is used to generate X-rays. Since it is composed of an X-ray tube, a booster coil, and a lead skin, it is generally cylindrical in shape and weighs 30-50kg.
随着科学技术的不断进步，依赖于散热技术的不断成熟，原来水冷式DR板改进成风冷式后体积大大减小，做成便携式DR成像板后可广泛运用于工业数字射线透照成像。由于其省略了传统胶片透照技术暗室处理环节，大大提高了工作效率，另外使用DR射线成像可以大大的减少工作人员放射剂量的吸收，且形成的数字文件便于保存和网络传输。 With the continuous advancement of science and technology, relying on the continuous maturity of heat dissipation technology, the original water-cooled DR board is improved to an air-cooled type, and the volume is greatly reduced. After being made into a portable DR imaging board, it can be widely used in industrial digital radiographic imaging. Because it omits the darkroom processing of traditional film transillumination technology, the work efficiency is greatly improved. In addition, the use of DR radiography can greatly reduce the radiation dose absorbed by the staff, and the formed digital files are convenient for storage and network transmission.
但是，由于其自身结构的原因，现在市面上主流的便携式DR板多在3-15kg，且在现场使用过程中，由于其体积大、重量重且具有辐射剂量，透照时摆放会成为一个比较困难的问题。 However, due to its own structure, most of the mainstream portable DR boards on the market now weigh 3-15kg, and during on-site use, due to their large size, heavy weight and radiation dose, placing them during transillumination will become a problem. more difficult question.
卧式GIS设备一般直径较大（一般500-2000mm），高度较高（一般1000-10000mm）（如卧式压力容器、管道、气体绝缘金属封闭开关设备等），且多为三相结构，彼此之间空间狭小，现场X射线探伤不仅位置复杂，且很难实现单次安装之后完成探伤任务。 Horizontal GIS equipment generally has a large diameter (generally 500-2000mm) and a high height (generally 1000-10000mm) (such as horizontal pressure vessels, pipelines, gas-insulated metal-enclosed switchgear, etc.), and most of them are three-phase structures. The space between is narrow, and the location of on-site X-ray flaw detection is not only complicated, but also it is difficult to complete the flaw detection task after a single installation.
卧式(三相)GIS设备进行现场透照时，一般采用支架将射线机机头安装或悬挂到足够高度的方式。由于现场环境复杂，一般透照一次必须使用大量的人力，花费大量的时间，还因高空作业造成了很多安全隐患，危害人身、设备安全。 When horizontal (three-phase) GIS equipment is used for on-site transillumination, brackets are generally used to install or hang the head of the X-ray machine to a sufficient height. Due to the complex on-site environment, a large amount of manpower and time must be used for one transillumination, and many safety hazards are caused by high-altitude operations, which endanger the safety of people and equipment.
