The elevator chain wheel driving device comprises a main body frame, a driving motor and driving rails are arranged in the main body frame, the driving rails are fixed to the two sides of an elevator shaft through rail fixing frames, and a chain wheel rack is installed in the middle of the driving rails; the chain wheel drivers are located on the two sides of the main body frame and elastically connected with the main body frame, driving chain wheels are arranged in the chain wheel drivers, and the driving chain wheels are meshed with the chain wheel racks; wherein the driving motor transmits the rotating torque to the driving chain wheels on the two sides through the transmission shaft, and the driving device obtains the counter-acting force of the chain wheel racks, so that the driving device moves up and down in the driving track. The lift car can run without traction force of a cable, the lift car can be braked only through braking of the driving device, complex elevator safety components are omitted, and under the condition that an elevator encounters an emergency or the cable is broken, the situation that traction force of the lift car is suddenly lost, and the lift car overspeeds and falls is avoided; and the elevator or people taking the elevator are safer.

    升降电梯链轮驱动装置,包括主体框架,主体框架内设有驱动电机,驱动轨道,驱动轨道通过轨道固定架固定在电梯井道两侧,链轮齿条安装在驱动轨道中间;链轮驱动器,链轮驱动器位于主体框架两侧,且与主体框架弹性连接,链轮驱动器内设有主动链轮,主动链轮与链轮齿条的啮合;其中,驱动电机通过传动轴把转动力矩传递到两侧的主动链轮,驱动装置得到链轮齿条的反作用力,使驱动装置沿着驱动轨道内上下运动。实现轿厢不需要缆绳曳引力运行,仅依靠驱动装置的制动就能制停轿厢,省去复杂的电梯安全部件,使得电梯在遇到紧急情况或者缆绳断裂的情况下,避免了导致轿厢的牵引力突然丧失,导致轿厢超速坠落,使得电梯或者乘坐电梯的人更加的安全。
