The invention discloses a driving device of a traction-free structure elevator, the cross section of a rail is I-shaped, the rail comprises an upper wing plate, a lower wing plate and a connecting part, the two ends of the connecting part are respectively connected with the middle part of the upper wing plate and the middle part of the lower wing plate, and 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, the force application unit is connected with the execution unit and tightly presses the driving tires on the face, away from the connecting part, of the upper wing plate, the power unit is connected with the driving tires and drives the driving tires 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. And the driving device is guided to run only along the length direction of the track. The driving tires are pressed on the outer side faces of the upper wing plates of the rails, the wheels of the limiting units are pressed between the upper wing plates and the lower wing plates, the height of the rails only needs to be larger than the outer diameter of the wheels of the limiting units, the depth size of a well is reduced, the force application units are of a symmetrical structure, and the tires are evenly pressed.
本发明公开了一种无曳引结构电梯的驱动装置,轨道的横截面为工字型,轨道包括上翼板、下翼板和连接部,连接部的两端分别连接上翼板的中部和下翼板的中部,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,施力单元为对称结构,轮胎受压均。
