The invention provides a self-locking structure of a traction-structure-free elevator driving device, the driving device comprises a self-locking structure, a driving motor and at least two driving wheels, the self-locking structure comprises a center frame, at least one set of force applying pieces and at least one set of supporting arms, the supporting arms are installed on the center frame, and the force applying pieces are arranged on the center frame. At least one supporting arm can rotate relative to the center frame, at least one driving wheel is installed on each set of supporting arms, the force applying pieces are connected with the supporting arms and connected with loads, and under the action of the loads, the supporting arms are driven by the force applying pieces to rotate. The angles of the supporting arms and the center frame are adjusted through rotation of the supporting arms, and the force of the driving wheels installed on the supporting arms for pressing the rail is adjusted. Self-locking can be achieved, the safety of the elevator system is improved, and meanwhile rolling of the driving wheels along the rails is not affected. The force application arm of tire pressure is increased, the stress of the force application piece is reduced, the tilting moment arm of the tire is reduced, and the tilting force borne by the tire is reduced.

    本发明提供了一种无曳引结构电梯驱动装置的自锁结构,所述驱动装置包括自锁结构、驱动电机和至少两个驱动轮,所述自锁结构包括中心架、至少一组施力件和至少一组支撑臂,支撑臂安装在中心架上,至少一个支撑臂相对于中心架可以转动,每组支撑臂上安装有至少一个驱动轮,施力件与支撑臂连接,施力件连接载荷,在载荷的作用下,通过施力件带动支撑臂转动,通过支撑臂的转动调节支撑臂和中心架的角度以及调节安装于支撑臂上的驱动轮压紧轨道的力。本发明可实现自锁,提高了所述电梯系统的安全性,同时不影响驱动轮沿着轨道的滚动。增大了轮胎受压的施力力臂,减小了施力件的受力,减小了轮胎倾翻力矩力臂,减小了轮胎承受的倾翻力。
