An elevator parking brake, a method for operating an elevator parking brake, and a control device for an elevator parking brake are provided. An elevator parking brake includes a parking brake frame attachable to an elevator car; a brake pad configured to contact a guide rail that guides the elevator car along the elevator shaft; and an actuation mechanism mounted on the parking brake frame for bringing the brake pad into contact with the guide rail and retracting the brake pad from the guide rail. The actuation mechanism includes a motor, an actuation member, and a conversion mechanism configured to convert rotational motion of the motor into linear motion of the actuation member. The actuation member contacts the brake pad with the guide rail and retracts the brake pad from the guide rail. The switching mechanism further includes a cam mechanism having a cam member driven in rotation by rotational movement of the motor, a drive profile of the cam member being in contact with the actuation member. The drive profile is configured to convert rotational movement of the cam member into linear movement of the actuation member.
提供了电梯驻车制动器、用于操作电梯驻车制动器的方法以及用于电梯驻车制动器的控制装置。电梯驻车制动器包括驻车制动器框架,其可附接到电梯轿厢;制动衬块,配置成与沿电梯竖井引导电梯轿厢的导轨接触;以及致动机构,其安装在驻车制动器框架上,用于使制动衬块与导轨接触并使制动衬块从导轨缩回。致动机构包括马达、致动构件和转换机构,转换机构构造成将马达的旋转运动转换成致动构件的线性运动。致动构件使制动衬块与导轨接触并使制动衬块从导轨缩回。转换机构还包括:凸轮机构,其具有凸轮构件,凸轮构件通过马达的旋转运动而被驱动旋转,凸轮构件的驱动轮廓与致动构件接触。驱动轮廓构造成将凸轮构件的旋转运动转换成致动构件的线性运动。
