The invention relates to a fixed-air-gap type permanent magnet eddy-current brake device for an elevator. The device comprises a built-in permanent magnet type linear type eddy current brake and a mechanical magnet adjusting operating mechanism. The built-in permanent magnet type linear type eddy current brake comprises a conductor stator and a built-in permanent magnet promotor; the conductor stator is fixed to an elevator shaft; the permanent magnet promotor is fixed to the outer side of an elevator lift car; an air gap exists between the conductor stator and the permanent magnet promotor; and the relative position between the conductor stator and the permanent magnet promotor is fixed through a guide rail. According to the fixed-air-gap type permanent magnet eddy-current brake device for the elevator provided by the invention, the position of a magnet adjusting plate is adjusted through the mechanical operating mechanism, and the coupling magnetic flux between the permanent magnet promotor and the conductor stator is controlled, so that the brake force of the permanent magnet eddy-current brake device is adjusted. Aiming at the elevator working conditions with different loads, according to the fixed-air-gap type permanent magnet eddy-current brake device for the elevator provided by the invention, through an electric control device, the flexible brake force and the elevatorlift car brake operation speed can be adjusted; and under the circumstance that the elevator is suddenly failed so as to fall at high speed, one-key eddy-current brake can be realized, and the elevator falls at low speed and constant speed so as to fall on the ground stably.

    本发明涉及一种固定气隙型电梯用永磁涡流制动装置,该装置包含一个内置永磁式直线型涡流制动器和一个机械调磁操动机构。内置永磁式直线型涡流制动器包含导体定子和内置式永磁动子;导体定子固定于电梯井,永磁动子固定于电梯轿厢外侧,导体定子与永磁动子之间存在气隙,通过导轨固定两者之间的相对位置。本发明通过机械操动机构调节调磁板位置,控制内置式永磁动子与导体定子之间的耦合磁通量,实现永磁涡流制动器制动力的调节。针对不同载荷的电梯工况,本发明通过电控装置,可以实现灵活的制动力及电梯轿厢制动运行速度调整;在电梯突然故障急速下坠情况下,可以实现一键涡流制动,低速匀速下降,平稳落地。
