Transverse and vertical conversion device and method for overturning cylindrical shell of underwater vehicle

The invention discloses a transverse and vertical conversion device and method for overturning a cylindrical shell of an underwater vehicle, and aims to solve the problems that in the current market, a crane is mostly adopted for assisting in overturning of the cylindrical shell with large caliber and heavy weight, and the cylinder shell can be overturned only by assistance of several persons except the crane. The mode is long in time consumption and needs a large number of workers, and people injury accidents are easily caused by misoperation. The device is purely mechanical, simple in structure, easy to machine and operate, reliable in work, accurate in turning angle and high in mechanical efficiency, has self-locking performance, and is high in turning efficiency, few in needed personnel and high in safety coefficient compared with an existing turning mode. 本发明公开了用于水下航行器圆柱体壳体翻转的横竖转换装置和方法，目前市场上对于大口径，重量重的圆柱体壳体的翻转，多采用航车进行辅助翻转，除了航车外往往还需要几个人协助才能够翻转。这种方式耗时较长、需要人员多、操作不当还容易造成伤人事故。本装置纯机械、结构简单、易加工，易操作、工作可靠，转角准确、机械效率
