The invention discloses a mechanical self-locking pulley for power maintenance. The mechanical self-locking pulley for the power maintenance comprises an internal tooth idler wheel, a pawl assembly, a clamping plate frame and an anti-disengaging hook, the pawl assembly comprises a fixing shaft, symmetrical wing discs and pawls; the fixed shaft is horizontally arranged, the symmetrical wing disc is vertically fixed on the fixed shaft, the tail ends of the two wings are respectively hinged with the pawls, and the two wings are provided with limiting baffle plates at the hinged parts; the inner tooth idler wheel is a cylinder, and the inner wall of the inner tooth idler wheel is provided with limiting teeth in a looping mode; the pawl assembly is concentrically sleeved with the inner tooth idler wheel, and the tail end of a pawl is inserted into the limiting teeth; the clamping plate frame is an inverted-U-shaped frame, two ends of the fixed shaft are connected with the lower parts of two side arms of the clamping plate frame, and two ends of the internal tooth idler wheel are rotatably connected with the lower parts of the two side arms of the clamping plate frame; the anti-disengaging hook is fixed to the upper end of the clamping plate frame. During lifting, the inner tooth idler wheel rotates in the forward direction, the limiting teeth drive the pawls to move normally, after lifting is stopped, the inner tooth idler wheel rotates in the reverse direction, the limiting teeth drive the pawls to be clamped by the limiting blocking pieces of the symmetrical wing discs, the pulleys are locked, and falling is prevented.

    本发明公开了一种电力维修用机械自锁滑轮,包括内齿滚轮、棘爪组件、夹板架和防脱挂钩,棘爪组件包括固定轴、对称翼盘和棘爪;固定轴水平布置,对称翼盘垂直固定于固定轴上,两翼末端分别铰接棘爪,两翼在铰接处设置有限位挡片;内齿滚轮为圆筒体,其内壁设置有成圈设置有限位齿;内齿滚轮同心套置于棘爪组件外,棘爪的末端插入限位齿中;夹板架为倒U形架,固定轴的两端与夹板架的两侧臂下部连接,内齿滚轮的两端与夹板架的两侧臂下部可转动连接;防脱挂钩固定于夹板架的上端。当提升时内齿滚轮正向转动,限位齿拨动棘爪正常活动,停止提升后内齿滚轮逆向转动,限位齿带动棘爪被对称翼盘的限位挡片卡住,将滑轮锁死,防止掉落。
