Monorail crane driving device

A monorail crane driving device belongs to supporting facilities of an underground coal mine production and transportation system, comprises a base, a motor, a speed reducer and a driving wheel, and is characterized in that the motor and the speed reducer are connected with a swing arm and are in transmission through a spline; and the driving wheel is connected with the speed reducer and is drivenby a flat key. The lifting appliance is small in size, the lifting height is correspondingly increased, and the transmission efficiency is improved. 一种单轨吊驱动装置，属于煤矿井下生产运输系统的配套设施，它包括底座、电机、减速机、驱动轮，底座上面安装有电机、减速机，其特征是电机与减速机连接有摆臂，电机与减速机通过花键传动；驱动轮与减速机连接并通过平键传动。本实用新型体积小，相应地增加了起吊高度，提高了传动效率。
