At the same time, a large amount of wiping paper is needed to repeatedly wipe and clean the reagents sprayed on the pipes (containers) during the inspection process. After the inspection is completed, the used garbage needs to be cleaned and stored; this requires the inspectors to carry a lot of inspection items with them during the inspection.
[0003] The common ways of carrying items currently include: Method 1, putting the inspection items into the pockets of work clothes and carrying them with you, but due to the limited pockets of work clothes, the items carried each time are small or incomplete, which cannot meet the needs of inspection, and too many items in the pockets of work clothes will cause inconvenience in movement, and there are safety risks during the inspection process; Method 2, putting the inspection items in a tool bag and carrying them, although the carrying capacity is large, because the inspection items are all placed in one bag, it is inconvenient to search when using, especially in a small working space, the poor light makes it more difficult to access. When carrying multiple inspection items in the above two ways, when conducting non-destructive testing of high-altitude pipelines (containers), it is necessary to climb a temporary high-altitude frame or a vertical ladder with a guardrail to reach the inspection location, which is neither convenient nor safe during the climbing process, and it is also unsafe when conducting inspections in the high-altitude inspection area.
[0004] Therefore, it is urgent to develop a carrying device that can store or carry multiple inspection items at the same time, and the inspection items can be stored clearly, carried safely and reliably, and taken out conveniently and quickly. Utility Model Content
