Technical Field
The utility model relates to the technical field of aero-engine sealing and storage, in particular to a special support auxiliary mechanism for engine sealing and storage.
Background
When the aviation engine is stored, the following situations are mainly avoided: 1. etching; 2. foreign matter enters the engine; 3. climate and weather changes adversely affect the engine.
For the engine, the engine needs to be opened for maintenance again according to the time of engine sealing and then sealing. For example, the LEAP-1A (A302 NEO) engine may last for up to 90 days (twice a refresh) for no more than 30 days, and up to 180 days (once a refresh) for no more than 90 days.
When the disassembled aviation engine is sealed, cleaning, derusting, paint supplementing, external oil sealing, packaging by adopting an aluminum plastic film wrapper, industrial sheepskin paper packaging and the like, finally sealing the case (nitrogen or dry air with the pressure of 0.3 atmosphere is required to be flushed during sealing the case), and finally placing the case in a warehouse.
The inventor finds that the engine of a helicopter of a certain model is placed in a warehouse in sealing, and the warehouse also keeps a dry environment, but the engine part close to the ground is more easily corroded; and the engine is arranged at a certain height from the ground, so that the engine is not easy to corrode. It is hypothesized that the closer to the ground, the more likely it is to get wet.
At present, the mode of adjusting the engine away from the bottom surface is realized by adopting a boat car or a forklift, and the space of a warehouse is limited, so that the method is very inconvenient. Based on this, a bracket mechanism is designed to assist in engine containment (mainly for lighter weight engines, although similar concepts can be used on heavy duty engines).
