The invention discloses a traction-free structure elevator with friction driving devices, at least one driving device is arranged, the at least one driving device is located above a suspension device, the driving device is hinged to the suspension device, the driving device comprises a limiting unit, an execution unit, a power unit and a force application unit, the execution unit comprises a plurality of driving tires, and the power unit is connected with the force application unit. The force application unit is connected with the execution unit and tightly presses the driving tire on the face, away from the connecting part, of the upper wing plate, the power unit is connected with the driving tire and drives the driving tire to rotate in the mode of being attached to the upper wing plate, and the force application unit is further connected with the limiting unit and tightly presses the limiting unit on the rail to guide the driving device to only run in the length direction of the rail. The driving device is hinged to the suspension device, the driving tire is pressed on the outer side face of the upper wing plate of the rail, the wheel of the limiting unit is pressed between the upper wing plate and the lower wing plate, the height of the rail only needs to be larger than the outer diameter of the wheel of the limiting unit, the depth size of a well is reduced, and the structure of the driving device is simplified.
本发明公开了一种具有摩擦驱动装置的无曳引结构电梯,驱动装置设有至少一个,至少一个驱动装置位于悬架装置的上方,驱动装置和悬架装置铰接,驱动装置包括限位单元、执行单元、动力单元和施力单元,执行单元包括多个驱动轮胎,施力单元连接执行单元并将驱动轮胎紧压在上翼板的远离连接部的一面,动力单元连接并带动驱动轮胎贴合上翼板转动,施力单元还连接限位单元并将限位单元紧压在轨道上,引导所述驱动装置仅沿着轨道的长度方向运行。本发明驱动装置和悬架装置铰接,将驱动轮胎压紧在轨道上翼板的外侧面,限位单元的轮子压紧在上翼板和下翼板之间,轨道的高度只需要大于限位单元轮子的外径,减小了井道深度尺寸,简化了驱动装置的结构。
