The invention discloses a maintenance-free elevator guide wheel, which comprises a guide wheel body, a mounting frame and a rotating shaft. The rotating shaft is mounted on the outer walls of the twosides of the mounting frame through bearing pedestals, and a supporting frame is welded to the outer wall of the top of the mounting frame; a rotary disc is fixed to the outer wall of one end of the rotating shaft through a bolt; a connecting column is welded to the outer wall of one side of the rotary disc; the outer wall of the connecting column is slidably connected with a power rod through a sliding groove; one end of the power rod is slidably connected with a connecting block through a shaft; and a piston column is welded to the outer wall of the top of the connecting block. By arrangingan air nozzle, a piston cylinder and the piston column, impurities on the outer surface of the guide wheel can be removed by airflow generated due to reciprocating motion of the piston column in the piston cylinder, and the abrasion phenomenon caused by the impurities existing between a steel wire rope and the guide wheel body is avoided; and by arranging the connecting column, the power rod and the rotary disc, circular motion can be converted into reciprocating motion while the guide wheel rotates, and power is provided for the piston column.

    本发明公开了免维护型电梯导向轮,包括导向轮主体、安装架和转轴,所述转轴通过轴承座安装于安装架两侧外壁,所述安装架顶部外壁焊接有支撑架;所述转轴一端外壁通过螺栓固定有转盘;所述转盘一侧外壁焊接有连接柱;所述连接柱外壁通过滑槽滑动连接有动力杆;所述动力杆一端通过轴滑动连接有连接块;所述连接块顶部外壁焊接有活塞柱。本发明通过设置气嘴、活塞筒和活塞柱,能够利用活塞柱往复运动于活塞筒内产生的气流清理导向轮外表面的杂质,避免钢丝绳与导向轮主体之间因存在杂质而发生磨损现象;通过设置连接柱、动力杆和转盘,能够在导向轮转动的同时将圆周运动转化为往复运动,为活塞柱提供动力。
