Abstract :
The 7000 m deep-ocean rock drill is an important equipment of prospect for ocean mineral resource. It is made up of orientation outfit, turning outfit, pushing outfit, drill tool, framework, control system and safeguard system, etc. The main parameters are accounted, and the basic structure, function, working principle and technical parameters of the 7000 m deep-ocean rock drill are introduced in this paper. The key technical difficulty of drill tool manufacture, tiny landform adaptability, safeguard system, the control of low force when chisel in, the control of weight with whole machine are resolved.
