Design and analysis of dual purpose tripod wheeled stretcher for Navy and Army

A rescue stretcher is designed for the evacuation of wounded in the ship or on the land. Through the tripod and guide wheel device, it can flexibly operate in the narrow internal channel of the ship, complete the transportation and rescue of the wounded in the internal channel of the ship, and at the same time, the transportation of the wounded on land can realize the wheeled transportation and reduce the physical consumption of stretchers. Cocoon basket structure can effectively locate the wounded body and reduce the secondary injury. In this paper, the design scheme of the stretcher is given, and the Adams motion analysis is carried out. The prototype is built up the gangway model for climbing test, and the stretcher climbing gangway function is realized, and the expected effect is achieved.
