The invention discloses a brake shoe. The brake shoe comprises a brake shoe frame, a brake shoe sheet on the brake shoe frame and an electromagnetic coil for controlling braking of the brake shoe sheet. At least two conductive trigger rods are inserted into the brake shoe frame and the brake shoe sheet, the inner ends of the trigger rods are arranged in the brake shoe sheet, and the outer ends ofthe trigger rods are wrapped with insulating layers and connected with internal wires. The brake shoe also comprises a first external wire and a second external wire which are connected to the two ends of the electromagnetic coil respectively, the internal wire of at least one triggering rod is connected to the first external wire, and the internal wires of the remaining triggering rods are connected to the second external wire. The abrasion condition of the brake shoe sheet can be automatically detected, when the brake shoe sheet is abraded to a certain degree, a detection device is triggered, an elevator safety circuit is disconnected, then an elevator is stopped, and danger is avoided.

    本发明公开了一种制动器闸瓦,包括闸瓦架、设于闸瓦架上的闸瓦片、以及用于控制闸瓦片制动的电磁线圈,闸瓦架与闸瓦片上插装有至少两根导电的触发杆,触发杆的内端设于闸瓦片内,触发杆的外端包裹有绝缘层并连接有内接导线,还包括分别连接于电磁线圈两端第一外接导线与第二外接导线,至少一根触发杆的内接导线连接于第一外接导线,其余触发杆的内接导线连接于第二外接导线。能够自动检测闸瓦片的磨损情况,当闸瓦片磨损到一定程度,触发检测装置,电梯安全回路断开,使电梯停梯,避免发生危险。
