A trolley conductor energy storage type construction elevator comprises a power grid, a charger, trolley conductors, a battery pack unit, a direct current converter, an electric control component, a motor, an inverter and a brake, the charger is electrically connected with the power grid, the trolley conductors are electrically connected with the charger, the battery pack unit is electrically connected with the trolley conductors through a brush, the direct current converter is electrically connected with the battery pack unit, the electric control component is electrically connected with the direct current converter, the motor is connected with the electric control component, and the inverter is electrically connected with the motor. When power is on, the trolley conductors are connected with the power grid to drive the construction elevator and charge the battery pack unit; when power is off, the battery pack unit is utilized to drive the construction elevator; the installation of power cables, cable trolleys and cable protectors is reduced, so that the intensity of installation is decreased; meanwhile, the shutdown of the construction elevator as the result of the breakage of the conductors of power cables and the outage of a power station is prevented, consequently, safety risk is decreased, and the production efficiency and usability of the construction elevator are increased; and meanwhile, when the construction elevator goes down, the redundant energy generated by the regenerative braking of the motor can be converted into electricity which can charge the battery pack unit.
