摘要

PURPOSE: A burner boom hydraulic cylinder structure is provided to prevent the corrosion of rods by preventing the rod of a cylinder from being exposed to outside when parking a burner boom. CONSTITUTION: A burner boom hydraulic cylinder structure(100) comprises burner rooms(110,120), a rotating connection unit(130), an outer cylinder(150), and an inner cylinder(170). The burner rooms are connected to one end of the burner boom. The rotating connection unit One end of the burner boom is connected to a drill ship by the rotating connection unit while being rotated.
