The invention discloses a construction hoist. The construction hoist comprises a guide rail, a cage and a motor group, wherein the cage is assembled on the guide rail; the motor group is used for driving the cage to ascend on the guide rail; the output end of the motor group is connected with and drives the cage to ascend on the guide rail; the motor group is connected with an energy storage device used for storing renewable energy generated when descending potential energy drives the motor group to passively operate in the descending process of the cage, and a small power generation device used for providing auxiliary operation energy for the motor group; the energy storage device and the small power generation device are both connected to a charging and discharging control circuit; and the charging and discharging control circuit is connected with the motor group through a frequency converter. Normal operation of the construction hoist can be met without accessing a power grid to supply power to the construction hoist, so that energy consumption is reduced, and the construction hoist is energy-saving and environment-friendly.

    本发明公开了一种施工升降机,包括导轨和吊笼,吊笼装配在导轨上,施工升降机还包括有用以驱动吊笼在导轨上运动上行的电动机组,电动机组的输出端连接并驱动吊笼在导轨上运动上行,电动机组连有用于储存吊笼运动下行过程中下行势能带动电动机组被动运行所产生的再生能源的储能装置以及用于为电动机组提供辅助运转能源的小型发电装置,储能装置和小型发电装置均连接在充放电控制电路上,充放电控制电路通过变频器连接电动机组。无需接入电网进行施工升降机的供电,即可满足施工升降机的正常运行,从而节约能源的消耗,既节能又环保。
