The invention provides a double-spiral-wheel-driven elevator. The double-spiral-wheel-driven elevator is provided with a lift car, wherein driving rails are arranged on the left side and the right side of the lift car and fixed to the two sides of an elevator shaft through rail fixing frames, rail supporting assemblies are installed in the middles of the driving rails, a counterweight rail is fixed to one side or the rear side of the elevator shaft through the rail fixing frames, the upper end of a counterweight device is connected with a mooring rope and sequentially passes through a counterweight guide wheel, a lift car guide wheel, a double-spiral-wheel driving device and the lift car, no complex mechanical speed changing device exists, no more parts and no production and machining technology with special requirements exist, the elevator has the incomparable advantages of safety, maintainability, purchase, use and maintenance cost compared with a traction type elevator, the lift car is driven by the double-spiral-wheel driving device to ascend and descend in the elevator shaft, a traction machine wheel in the prior art is not needed, and the phenomenon that the lift car falls due to sudden loss of traction force of the lift car is avoided when an elevator encounters an emergency or a cable is broken.

    本发明提供了双螺旋轮驱动升降电梯,设置有轿厢,在轿厢的左右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,轨道支承组件安装在驱动轨道中间,对重轨道通过轨道固定架固定在电梯井道一侧或后侧,对重装置上端连接缆绳依次经过对重导向轮,轿厢导向轮,双螺旋轮驱动装置,轿厢,没有复杂的机械变速装置,也没有较多的零部件和特殊要求的生产加工工艺,并且具有曳引式电梯无可比拟的安全性,可维护性,购置及使用,维护成本优势,依靠双螺旋轮驱动装置驱动轿厢在电梯井道内升降,不需要传统技术内的曳引机轮,使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坠落。
