The invention discloses an elevator guide shoe adding device with a stall protection function and a working method of the elevator guide shoe adding device. The device comprises a beam frame, a vertical guide rail and a composite guide shoe. The composite guide shoe comprises a guide shoe base plate, a guide mechanism and an emergency braking mechanism. The emergency braking mechanism is installed on the guide shoe base plate. The emergency braking mechanism comprises a wedge-shaped pushing plate, a wedge-shaped braking plate, an initial-section pushing mechanism and a tail-section lifting mechanism. The wedge-shaped brake plate is located on the side, close to the vertical guide rail, of the wedge-shaped push plate. The side face, facing the vertical guide rail, of the wedge-shaped push plate is an inclined face inclining downwards. The side face, deviating from the vertical guide rail, of the wedge-shaped brake plate is a downward inclined face. The initial section pushing mechanism with a dead point is matched with the inhaul cable lifting and slope guiding tail section lifting mechanism, the wedge-shaped braking plate is driven to move to the braking position, the wedge-shaped braking plate can be kept in a locked state after being in place, the wedge-shaped braking plate is not prone to being separated from the vertical guide rail, and therefore under the condition that a motor is not required to continuously conduct large-torque output, the braking efficiency is greatly improved. And stable braking force is provided.

    本发明公开了一种具有失速保护功能的加装电梯导靴装置及其工作方法;该装置包括梁架、竖直导轨和复合导靴。复合导靴包括导靴基板、导向机构和紧急制动机构。紧急制动机构安装在导靴基板上。紧急制动机构包括楔形推板、楔形制动板、初段推送机构和末段提拉机构。楔形制动板位于楔形推板靠近竖直导轨的一侧。楔形推板朝向竖直导轨的侧面为倾斜向下的斜面;楔形制动板背离竖直导轨的侧面为倾斜向下的斜面;本发明使用具有死点的初段推送机构与拉索提拉结合斜面导向末段提拉机构配合,带动楔形制动板移动至制动位置,且楔形制动板到位后能够保持锁定状态,不易与竖直导轨脱离,从而在不要求电机持续进行大扭矩输出的情况下,提供稳定的制动力。
