The invention provides an eddy current type brake device which is installed on an elevator car or a balance weight which moves along a guide rail extending in the vertical direction. An eddy current brake device includes a magnet unit and an operating mechanism. The magnet unit includes at least one magnet. The operating mechanism moves the magnet unit between an operating position at which the magnet unit approaches the guide rail to operate the brake and a non-operating position at which the magnet unit is farther from the guide rail than the operating position. The working mechanism has a spring and an actuator. The spring expands and contracts along an expansion and contraction direction, so that the magnet unit moves along the expansion and contraction direction, and the expansion and contraction direction is a direction from the elevator car or the balance weight to the guide rail. The actuator contracts the spring in the expansion/contraction direction.

    本发明提供涡电流式制动装置,其安装于沿着在上下方向上延伸的导轨进行移动的电梯轿厢或者平衡配重。涡电流式制动装置具备磁体单元和工作机构。磁体单元包括至少一个磁体。工作机构使磁体单元在工作位置与非工作位置之间进行移动,工作位置是接近导轨来使制动器工作的位置,非工作位置是与工作位置相比远离导轨的位置。工作机构具有弹簧和致动器。弹簧沿着伸缩方向进行伸缩,使磁体单元在伸缩方向上进行移动,伸缩方向沿着从电梯轿厢或者平衡配重朝向导轨的方向。致动器沿着上述伸缩方向使所述弹簧收缩。
