The chain wheel driven elevator comprises a lift car, driving rails are arranged on the two sides of the lift car, and the driving rails are fixed to the two sides of an elevator shaft through rail fixing frames. The counterweight rail is fixed on one side of the elevator shaft, and the counterweight rail plays a role in guiding the counterweight device to move up and down; the driving device is arranged at the top of the lift car, and the driving device drives the lift car to move up and down in the lift shaft; wherein the upper end of the driving device is connected with a mooring rope from the counterweight device. Compared with the prior art, the elevator machine room is simple in structure, 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, the lift car can still stop on the track through counter-acting force of the track when an elevator encounters an emergency or under the condition that the cable is broken, and the safety of the elevator is improved. The situation that the cable breaks and loses traction force, and consequently the lift car overspeeds and falls is avoided, and the elevator or people taking the elevator are safer.

    链轮驱动升降电梯,包括轿厢,在轿厢的两侧设置有驱动轨道,驱动轨道通过轨道固定架固定在电梯井道两侧;对重轨道,对重轨道固定在电梯井道一侧,对重轨道为对重装置上下运动起导向作用;驱动装置,在轿厢的顶部设置有驱动装置,驱动装置带动轿厢在电梯井道内上下移动;其中,驱动装置上端与来自对重装置的缆绳相连。本发明电梯机房结构比较简单,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,轿厢仍然可以依靠轨道的反作用力停在轨道上,避免缆绳断裂失去曳引力,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。
