Description

TECHNICAL FIELD

[0001] The utility model relates to an auxiliary device for compressing and shaping a civil aviation aircraft slide bag. BACKGROUND

[0002] The civil aviation aircraft emergency slide / raft is a time-life control component, and the slide must be disassembled for inspection and testing every 3 years or 5 years (the slide of an aircraft exceeding 15 years is disassembled for inspection and testing every year), and then the slide is refolded and packed. The slide / raft material is folded and packed in a packing box. In order to prevent the slide bag material from rebounding and expanding, the slide bag needs to be kept in a compressed state for a period of time before being packed. This step is generally completed in the following way: a pad is laid flat above the slide bag, and 2 to 4 people (different numbers of people are needed for different sizes of slide bags of various aircraft models and different levels of compression difficulty) uniformly compress the slide bag to the target thickness by hammering, pulling or stepping on the pad. The time required to complete the slide bag compression step by hammering, pulling or stepping on the pad is about 0.5 hours. During this operation process, the risk of injury to the workers is relatively high, and the large impact force in the packing process has a potential risk of damaging the high-pressure gas cylinder of the slide / raft, and the operator needs to control the force of hammering, pulling or stepping. Therefore, the existing slide bag compression and shaping method is not only low in efficiency, but also has a high risk. CONTENT OF THE UTILITY MODEL
