The invention discloses a quickly-mounting type high-speed coaxial intermediate reheat axial exhaust steam turbine. A left bearing seat and a right bearing seat are respectively and fixedly arranged on the upper sides of two ends of a base frame, two ends of rotors are horizontally erected on the left bearing seat and the right bearing seat, a high-pressure inner cylinder is arranged on the outerside of the rotors in a sleeving mode, and an outer cylinder is arranged on the outer side of the high-pressure inner cylinder in a sleeving mode. The right end of the high-pressure inner cylinder extends outwards and is connected with the inner wall of the outer cylinder to divide an inner cavity of the outer cylinder into a left-side high-pressure cavity and a right-side medium-low pressure cavity, and two sets of moving blades are respectively and oppositely arranged on the rotors of the left-side high-pressure cavity and the right-side medium-low pressure cavity. A main steam inlet is formed in the right end of an
