The invention discloses a high-speed hydraulic erecting mechanism based on a synchronous telescopic multi-stage cylinder and an energy accumulator. The high-speed hydraulic erecting mechanism comprises the synchronous telescopic multi-stage cylinder, the energy accumulator, a motor pump set, a switch valve I and a switch valve II; the motor pump set is connected with the energy accumulator and used for charging oil into the energy accumulator and storing energy; the energy accumulator communicates with a rodless cavity of the synchronous telescopic multi-stage cylinder through the switch valveII, and a rod cavity of the synchronous telescopic multi-stage cylinder communicates with an oil tank through the switch valve I; and oil in the energy accumulator enters the rodless cavity of the synchronous telescopic multi-stage cylinder through the switch valve II, oil in the rod cavity of the synchronous telescopic multi-stage cylinder returns to the oil tank through the switch valve I, thesynchronous telescopic multi-stage cylinder stretches out at a high speed, and therefore high-speed hydraulic erection is achieved.
